根据塑件的几何结构特点、和尺寸精度的要求,进行批量生产,而精度高的检查井模具制造困难,需要有特定的工作人员来进行生产制造,不能大批量生产。分型面的位置要利于模具加工、排气、脱模及成型操作,而检查井制品的表面质量也要得到保障。
According to the geometric structure characteristics of plastic parts and the requirements of dimensional accuracy, mass production is carried out. However, it is difficult to manufacture high-precision inspection wells, which requires specific staff to manufacture, and can not be produced in large quantities. The position of parting surface should be beneficial to die processing, exhaust, demoulding and forming operation, and the surface quality of inspection well products should also be guaranteed.
浇注系统包括主浇道、分浇道、浇口形状、位置、大小。排气系统包括排气方法、排气槽位置、大小,检查井模具要选择对应的顶出方式,例如顶杆、顶管、推板、组合式顶出等,来决定侧凹处理方法和抽芯方式。
The gating system includes main runner, sub-runner, gate shape, position and size. The exhaust system includes exhaust method, location and size of exhaust groove. The corresponding ejection modes, such as ejector rod, pipe jacking, push plate and combined ejection, should be selected to determine the side concave treatment method and core pulling method.
