蒸汽直接加热模具型腔的温度控制系统的研究
Research of Mould Temperature Control System for Heating the Mold Cavity Directly by Steam
摘要
Abstract
The surface quality of injection molding parts relates to the followup processing and product life. In or der to eliminate the defects and distorsion of the surface, the method of mould temperature control for directly heat ing the mold cavity by steam is presented, and the corresponding equipment was developed. This device is made of two subsystemswater steam purifying system and air cleansing system, it works in the way: the high temperature and pressure steam is passed into mold cavity to heat the surface of mold cavity , then the hot air is put into the mold cavity for clearing away the residual condensed water Programmable logic controller (PLC) is used to con trol the order and duration of the steam and the hot air, until the surface temperature reach the desired temperature. In this method,the metal of mould cores are heated for depth of only 1 mm ~ 2 mm form mold surface, so it only needs the very shorter warmup time and less electricity. The flow ability of meolten plastic, the temperature and pressure of the of its front are very high in this heating way, so the distorsion and the surface defects of the injection molding parts can be eliminated.关键词
