(1) Definici\u00f3n<\/h2>\n

El molde utilizado para fabricar productos de pl\u00e1stico se llama molde de pl\u00e1stico. producir<\/span> Los productos pl\u00e1sticos con tama\u00f1os, formas y propiedades espec\u00edficos, el pl\u00e1stico termoendurecible o termopl\u00e1stico, se calientan a una temperatura determinada y se colocan en una cavidad moldeada, que permanece intacta despu\u00e9s de enfriarse. Este proceso se denomina tecnolog\u00eda de conformado de pl\u00e1sticos.<\/span><\/p>\n

(2)Tipo de tecnolog\u00eda de conformado de pl\u00e1stico<\/h2>\n

La tecnolog\u00eda de conformado de pl\u00e1stico se clasifica principalmente en conformado por compresi\u00f3n, transformaci\u00f3n y conformado por inyecci\u00f3n seg\u00fan el m\u00e9todo de moldeo. Adem\u00e1s, existe el moldeo por soplado hueco, el conformado por espuma y el moldeado por vertido.<\/p>\n

(3)Molde de pl\u00e1stico y su estructura b\u00e1sica<\/h2>\n

La tecnolog\u00eda de conformado de pl\u00e1stico clasifica los moldes de pl\u00e1stico en moldes de compresi\u00f3n, moldes de transferencia, moldes de inyecci\u00f3n, moldes de soplado huecos, moldes de espuma y moldes de vertido.<\/p>\n

Existen muchos tipos de moldes de pl\u00e1stico, pero se componen \u00fanicamente de dos tipos principales: piezas de conformaci\u00f3n y piezas estructurales. A continuaci\u00f3n, se explica la estructura b\u00e1sica de los moldes de pl\u00e1stico con dos ejemplos de estructuras t\u00edpicas.<\/p>\n

\"Molde

1- Placa de sujeci\u00f3n de la mitad superior 2- Placa de crimpado 3- Placa de retenci\u00f3n de la cavidad 4- Poste gu\u00eda 5- N\u00facleo de rosca 6- N\u00facleo 7- Cavidad de la plataforma roscada 8- Refuerzo 9- Placa de sujeci\u00f3n de la mitad inferior 10- V\u00e1stago manual 11- Tubo de impulsi\u00f3n 12- Pasador 13- Tornillo<\/p>\n
