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。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。检查井模具要根据其冷却方式和加热方式来确定冷却加热沟槽的形状、位置和加热元件的安装部位。检查井模具要根据其材料、强度计算或者经验数据,来确定模具零件厚度、外形尺寸、外形结构及所有连接、定位、导向件的具体位置,检查井模具要根据其主要成形零件来确定其结构形式。检查井模具要根据各个部分的强度来确定计算出工作的零件尺寸。

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 mass production. 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. zengyingji.37ix.com.cnslglj.37ix.com.cnzengsuji.37ix.com.cnzengsujisl.37ix.com.cnzengliang.37ix.com.cn

zhidaijil.37ix.com.cnThe 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. The shape, position of the cooling and heating groove and the installation position of the heating element should be determined according to the cooling mode and heating mode of the inspection well mould. According to the material, strength calculation or empirical data, the inspecting well mould should determine the thickness, shape size, shape structure and the specific position of all connecting, positioning and guiding parts. The inspecting well mould should determine its structure form according to its main forming parts. The inspecting well mould should determine the size of the working parts according to the strength of each part.
