摘要
热流道系统是塑胶模具和产设备中的重要组成部分,配合使用于各种不同类型的塑胶零件成型,其工作原理是在注射模内装上分流板及热嘴,利用加热和温度控制的原理,使模具的流道部分保持熔融状态,制品的浇口如同直接接触到注塑机的射嘴一样,那么成品在脱模时就不会拖着一条或多条胶口。一套完整的热流道系统是由平衡式分流板、热嘴、高精度温度控制器组成。伴随着模具行业的发展,热流道系统也日益发展起来。本文详细介绍模具热流道系统应用与选择注意点。
Heat runner system plays an important role in plastic molds and production equipments, and it is in cooperation used for variety of plastic parts molding. Its working principle is that fitting on shunting plate and heat spout in injection mold,by means of the principle of heating and temperature control, keeps mold's runner segment fusing, as if the gate of plastic were directly in contact with the heat spout of an injection molding machine, which leads not to drag one or several plastic sprue when final products demold. A full set of heat runner system is made up of a balancing shunting plate,a heat spout and a high precision temperature controller.With development of mold industry,heat runner system is increasingly developing too.This paper particularly introduces the notices of application and selection of mold's heat runner system.
