SIMULACIÓN DE UN MOLDE DE RESPUESTA TÉRMICA RÁPIDA CON SISTEMA DE ENFRIAMIENTO CONFORMADO MEDIANTE FEM (SIMULATION OF A RAPID THERMAL RESPONSE MOLD WITH CONFORMED COOLING SYSTEM BY FEM)
Resumen
Resumen
En el presente estudio se analiza un molde de respuesta térmica rápida mediante el estudio de campos acoplados, sabiendo que el tiempo de ciclo depende en gran medida del tiempo de enfriamiento, se diseñan y evalúan canales conformados rectangulares utilizando análisis de elementos finitos y análisis térmico de transferencia de calor. Se propone un diseño de sistema de enfriamiento de canales conformados y se analiza térmicamente en dos pasos de carga. Por último, se realiza la evaluación estructural obteniendo los esfuerzos de Von Mises mediante campos acoplados y se observó la reducción del tiempo de calentamiento, así como la reducción del porcentaje de tiempo de enfriamiento del porcentaje total del ciclo, manteniendo los esfuerzos debajo de 500 MPa lo que prolonga la vida útil de los insertos del molde.

Abstract
In this paper, a rapid thermal response mold is analyzed by studying coupled fields, knowing that the time depends largely on the cooling time, rectangular conformal channels are designed and evaluated through finite element analysis and thermal transfer heat analysis. A cooling system design of conformal channels is proposed and thermally analyzed in two load steps. Finally, the structural evaluation is carried out, obtaining the Von Mises Stress through coupled fields and it was observed the heating time is reduced, as well as the reduction of cooling time percent of the total cycle time keeping below 500 MPa that the useful life of the mold inserts.
Keywords: Thermal Analysis, Rapid Thermal Respond Mold (MRTR), Injection Mold, Cycle time.
