FUNDAMENTALS OF OPTIMIZED MOLD COOLING SYSTEM DESIGN FOR INJECTION MOLDS

摘要

Mold cooling has evolved, just like mold machining has required faster machining, new mold cooling components are increasing efficiency of required mold cooling. Advancements through the years as specialized material selections for cooling components, conformal cooling inserts, and back again to components utilizing standard machining practices. There are new mold cooling components used to reduce machining time by reducing mold component lengths and therefore shortening plate thickness. Historically mold cooling was designed to circulate water or cooling medium through the mold base plates primarily and not necessarily within the cavities or cores. This practice usually required many different levels of cooling lines and thicker mold plate assemblies. The newer advancements create a circulation that is now optimized within mold plates and specialized within the cavities and cores to reduce mold heights.
