河北检查井模具厂

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..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
