压铸模中,使铸件脱出模具一般采用顶出机构的动力来实现。但是碰到型腔较深而壁薄的压铸件我们采用型芯固定在定模上,开模时用抽芯机构的办法,先将压铸件强行克服型芯的包紧力,使铸件体停留在动模上,然后通过推出机构使铸件出型腔。但在某些情况下,上述办法不太适宜。 Die casting, casting out of the mold generally use the power of the ejection mechanism to achieve. But encountered deep and thin-walled cavity die-casting we use the core fixed in the fixed mold, the mode of core-pulling mechanism used when the first cast to force to overcome the tightness of the core, the casting body to stay In the dynamic mode, and then through the introduction of institutions casting a cavity. However, in some cases, this approach is not appropriate.
