Molds are tools used to make molded articles. Among them, the injection mold is a processing tool used in the mass production of some complex shapes. Specifically, it refers to injecting the melted material into the mold cavity by high pressure, and after cooling and solidifying, a molded product is obtained.
模具一般采用延长冷却时间的方式或是在型芯中制有更多的冷却水路来提高冷却效果,即:在注塑模具的型腔和型芯中都会设置冷却水路,通过在冷却水路中流入冷却水对塑料件进行快速冷却定型。但是,目前的冷却水路通常为单独的冷却水路,即:在模具的上下模板上分别设置降温水路,或者通过喷头等喷淋进行辅助降温冷却,其不但造成多水路互不连通的问题,而且,冷却时,水路复杂且冷却效果差,存在水流难以收集的问题。The mold generally adopts the method of prolonging the cooling time or making more cooling water channels in the core to improve the cooling effect.
