What Are the Ways to Install Mold Clamps?

Replacement or addition of a mold clamp needs bolt and nuts to turn about 0.5 to 1 for perfect installation.

Different kinds of attachments are reliable with only a single bolt. Excessive replacement of bolt is not necessary.

Firstly, check the quick-change mold clamps and bolts size of the previous or current injection molding machines, then install a new set of mold clamps.

On the second turn, lose the nuts of the clamping unit, displace the previous quick-change mold clamps and the bolts present in the clamping system.

After that, install the new mold clamps with the clamping units such as nuts and bolts for locking correctly. Use the wrench to press or tight the nuts and bolts.

In the final step, clean the machine properly and test the new clamping molds to see if the process performs well or not.

What Is the Purpose of Mold Clamps?

Yushine’s mold clamp is a type of auxiliary attachment in the mold processing system.

The vital role which a mold clamp plays is to make the workpiece not vibrate and shift during the processing of an injection mold machine.

The mold clamp is good at shoeing the correctness of the molded workpiece and provides a perfect finish.

Mold clamp quality has a significant effect on the quality delivery of the molded product. Yushine’s forged die mold clamp has greater strength, little volume, and easy and effective functioning.

Mold clamps fix the iron plates. The iron plate assembles on the hole of the shaft. When setting the mold clamp with the screws, the movement of the rod decreases.

What do you about the Manufacturing Process of Mold Clamps?

Yushine is leading in the marketplace for manufacturing mold clamps with high quality that result in quality mold products. The process of manufacturing mold clamp is as follow:

Mold clamps get forged from medium carbon steel (#45 medium); such material increases the mold clamps hardness up to 30HRC.

High temperature and intense forging by air hammer are the methods to produce mold clamps. The milling machine is helpful in making the surface plane. Scratches also get plain by milling machining.

The mold clamps are flat, reaching 0.02MM. Heat treatment makes their hardness more up to 35HRC to 40 HRC.

Various filaments overlap, copper foils assemble on one or every side of the filament, and after that, heat treatment applies to them to obtain a stack of mold clamps.

In this way, the surface of a mold clamp becomes blue or black and is corrosion-free. There are no chances of rusting with the blue or black surface of mold clamps.

What do you know about Mold Clamp Forming Oil?

The structure of a mold clamp consists of polypropylene resins and forming oil. Water-soluble and volatile stamping oil is synthetic water-soluble oil.

This stamping oil is beneficial in lubricating the mold clamps in plastic molding operations like pressing, pulling, and ejection.

This water-soluble and volatile-forming oil is applicable in high-strength operations. It is essential in plastic forming machines.

This oil is a mixture of additives such as oil additives, rust inhibitors, and others with good process power and hydrophilic nature.

Water-soluble and volatile forming oil is suitable for making metal sheets such as stainless steel sheets, silicon steel sheets, carbon steel, and non-ferrous metals.

So, the forming oil is useful in providing good lubrication to the mold clamps and protects them from various agents.

What do you know about the Clamping Precautions of Mold Clamps?

Be safe! Any clamping activity can be so dangerous for you. Yushine’s mold clamps fixation requires specific measures which need to follow to avoid any danger.

The precautions of mold clamps are as follow:

Appropriate size and quantity of mold clamp are necessary for the plastic processing machines to hold them tight in place.

Use a required size washer and bolts with a mold clamp. Before buying and using washers and bolts, match them with the mold clamps, whether they fit perfectly or not.

Daily check the nuts, bolts, washers, platen threads, and mold clamps to avoid cracking and bending. If the crack or bending occurs, replace them with new ones.

Daily inspect the fixation of the mold clamps. If mold clamps become loose, then re-tight them to avoid any hazard.

Try to use closed-toe mold clamps instead of open-toe mold clamps as they are more solid and hard.

Place the bolts near the mold clamps to provide high strength and rigidity.

Inspect the female platen threads and make sure bolts penetrate the platen threads one and one-half of the diameter.

What Is a Clamping Pressure of Mold Clamp? Why is it Important?

Several factors are essential to obtain excellent output from the plastic processing injection molding machines when setting the engine, most notably the clamping pressure of the mold clamp.

Clamping Pressure

It is a pressure that helps to position the mold near the injection molding machine. Clamping pressure is also a measurement of a force that holds the mold clamps.

For this reason, the clamping pressure needs to be high to perform a better operation and to avoid the early opening of mold clamps by the force of the injection.

If the pressure is not high, mold clamps will open early and causes a sparkle on the nearby parts.

Importance of Clamping Pressure

Clamping pressure is the variable that is quite helpful in measuring the capacity of the injection molding machine to get good results.

Clamping pressure has a great effect on the output product, and it also affects the costs and cycles of the product.

Clamping pressure is essential in the sense that if the mold is not tight enough, then the plastic will come out of the mold resulting in parting lines.

What do you know about the Clamping Rules of Mold Clamp?

Yushine’s mold clamps require some rules that help mold clamps last longer and maintain mold clamp hardness. The regulations for clamping are as follow:

  • Always use a piece of wood (scrap) between the wooden parts and mold clamp jaws to avoid damage to other components.
  • The load on the mold clamps needs to apply from the vertical side to avoid any damage. The vertical load is easy to distribute to the nearby parts.
  • Ensure using two mold clamps simultaneously to stop the movement or rotation of the mold.
  • Avoid over-tightening of the mold clamps as it causes damage to the clamps.

What Are the Ways to Calculate Clamping Force of the Mold clamps?

As you know, clamping force is the force on the mold by the clamping system in a plastic injection molding machine.

Clamping force needs to oppose the pressure, which results in the opening of the mold. Usually, the force rate is in terms of tons.

The clamping force needed highly depends upon the chamber pressure on the inner side of the mold and the specified area.

Material and the depths of the material affect the calculation of a clamping force.

What do you know about Adjustable-Type Mold Clamp?

Yushine’s step block clamps are well-known due to adjustable supporting blocks at the end of the mold clamps while clamping the workpiece. Adjustable-type step blocks come in a pair form, and each pair consists of two clamps.

The adjustable-type step block clamps act as a base for the mold clamps, which is helpful in correctly positioning the workpiece.

A combination of two-step adjustable clamps of variable sizes provides support below one step strap clamp.

Adjustable-type mold clamps need to position near enough to avoid bending of the workpieces. The slots, sides of the table, and base need to be free from all the dirt or debris.

Adjustable-type mold clamps must not be too long or short that result in danger or ineffective working. Adjustable-type mold clamps should come in a lubricated (oil or grease) form.

What Are the Specifications of Adjustable-Type Clamp Models?

Yushine’s adjustable-type mold clamps range in various models such as M12, M16, and M20. M16 and M20 models also come in rigid nature, and the color of these models is blue.

What Are the Applications of Injection Molding?

Injection molding is reliable where a continuous manufacturing process is going on. The injection molding process is applicable in various ranges such as:

  • In bottle tops
  • In wire spools
  • In toys industries
  • In making combs
  • In making musical gadgets
  • In storage tanks
  • For small tables
  • In automotive components

However, the injection molding process is excellent in producing high-quality plastic products.

If the injection machine is unable to set correctly or the clamping system is loose, the quality of the molded product can suffer a lot.

What do you know about Injection Molding?

Injection molding is a process to get molded products as output by providing heat to the plastic molten parts into the molds. After injection of material, the cooling or solidification process begins to get the desired shapes.

Injection molding is very helpful in the excessive production of plastic material. It resembles the process of injecting liquid with the help of a syringe. It is the main reason for naming it as injection molding.

Injection molding consists of an injection unit and the clamping unit, which contains mold clamps for proper fixture so that material will not come out when an extreme inward pressure results.

Process of Injection Molding

This process begins when a resin granule goes into the hopper, which is the inlet of the material. The resin granules get warm and liquefy into the cylinder.

The material gets forged with the help of a nozzle into the channels and then into the mold cavity.

After cooling and solidifying the plastic material, the mold opens, and the molded element get out of the mold.

Make sure the melted material distributes equally among the molds.

Injection molding is good at producing high-quality products by taking care of material of resin, the functioning of the molds, and the temperature and velocity of the injection machine.

Relation between Mold Clamps and Processing

Yushine’s mold clamps link with the injection machine clamping unit. Mold clamps help fix the parts tightly and do not let them bend. The bending of the elements may disturb the quality of the desired product.

Mold clamps in the clamping unit of the injection machine stop the vibration and oscillation of the workpiece at the time of processing.

What Is the Function of the Clamping Unit of the Injection Molding Machine?

The injection molding machine consists of two units named as injection unit and the clamping unit.

The function of the Yushine’s clamping unit is to open and close the mold or a die and to eject the products.

The clamping unit of the system further contains two forms labeled as toggle type and hydraulic type.

The clamping unit helps keep the mold lock against the pressure, which occurs when plastic moves towards the closed mold through injection pressure.

Hydraulic Clamp System

The benefit of this system is to regulate clamp pressure. It reduces the amount of energy consumed and friction produced.

A mobile platen attaches with the RAM of the hydraulic cylinder. The hydraulic cylinder consists of an inlet and outlet valve for oil lubrication.

The hydraulic cylinder has RAM on the inlet and outlet section, whose opening results in forward and backward motion of RAM coils and causes the movement of hardening plates of the machine.

This clamping system of the injection molding machine helps to control the mold clamps easily. It requires low maintenance.

Toggle Clamp System

The benefit of the toggle mold clamp is that it does not open automatically. The downside of this clamp system is that it often causes wear and damage to the nearby parts when remaining unchecked.

The toggle clamping system possesses two shafts linked at a fixed point. The end of the one shaft attaches with the stationary platen, and the other end of the shaft connects to a movable platen.

This type of clamping system performs with low power and cost. It is the optimistic plan of the mold.

The negative side is that this clamping of the mold becomes complex and challenging. It also requires a lot of maintenance.

What do you know about the Advantages of a Mold Clamp?

Yushine’s Injection mold clamps are available in a wide range of high-precision mold clamping. The advantages of mold clamps are as follow:

  • Mold clamp can be attached and replaced in no time (0.5 to 4.5 seconds)
  • Energy is not often required during the clamping process
  • The mold clamp plate does not require maintenance. It results in longevity
  • Clamp force distributes evenly on the near parts of the mold clamp and does not result in damage to the other part

How to Speed Up Mold Changes with the Help of Mold Clamp??

A quick mold change solution means another material is available to go into the next section, the automation is all set, and the mold clamps are ideally in place.

When a quick mold change system takes place, then the mold clamps in the exact previous area.

Yushine’s mold clamps have various changing solutions, which firstly make sure the proper processing of plastic injection molds or dies.

When a quick mold change occurs, properly fix the mold clamps to avoid any damage or sparkle to gain improved quality products.

Improved mold clamp fixation increases the safety of the mold. The mold runs smoothly and quickly in and out of the plastic injection machine during the mold change.

Check the automation system for the proper running of mold/die (material). If the mold does not clamp in an appropriate way, the plastic injection molding machine will face difficulty in functioning.

Mold change can also speed up with the help of automated clamps in the operator in a fraction of time which reduces the labor cost.
