Validación CAE, Moldeo por inyección, Rediseño y reparación de inserciones

Resumen

Las reparaciones y rediseños de piezas de moldeo por inyección de plástico generalmente son un proceso corto y directo que consiste en inspección, modelado y evaluación. El presente trabajo implementa una metodología para el rediseño y reparación de piezas moldeadas por inyección basada en el proceso frontal de desarrollo de conceptos. La metodología propuesta ayuda en la validación mediante Ingeniería Asistida por Computador (CAE) en la etapa de diseño mediante software CAD, asegurando la calidad de la reparación. Además, el desarrollo rediseñado se ha realizado de la mejor manera para obtener una mejor refrigeración, robustez o fluidez plástica. En esta investigación se implementa la metodología propuesta en un Sistema Hot Runner. Además, se realizó una simulación numérica para tres casos para evaluar la transferencia de calor y los tiempos de enfriamiento, encontrando las principales diferencias en la transferencia de calor debido a los canales rectangulares perforados o fresados, minimizando el tiempo para alcanzar la temperatura de eyección y las temperaturas del molde/pieza.
