Some key points in die design of rifeng pipe joint

We make pipe mould for Japan has nearly 100 sets, because the mold cavity of stitching is more, high demand for product appearance, the following is the company's engineering department summary of pipe fittings mold design certificate when some of the main points, dear colleagues, please read careful study.

1. Cavity layout. According to the geometric structure characteristics of plastic parts, size precision requirements, batch size, mold manufacturing difficulties, mold cost and other factors to determine the number of cavity and its arrangement.
2. Determine the parting surface. The position of the parting surface should be conducive to mold processing, exhaust, demoulding and molding operations, surface quality of plastic parts, etc.
3. Determine the casting system (shape, position and size of the main runner, runner and gate) and the exhaust system (method of exhaust, location and size of the vent).
4. Select the jacking method (jacking rod, jacking tube, pushing plate and combined jacking), and determine the side concave treatment method and core pulling method.
5. Determine the cooling and heating modes, the shape and position of the heating and cooling groove, and the installation position of the heating element.
6. According to mold material, strength calculation or empirical data, determine the thickness and dimension of mold parts, the shape and structure, and the position of all connecting, locating and guiding parts.
7. Determine the structural form of the main molding parts and structural parts.
8. Calculate the working dimensions of the molding parts considering the strength of each part of the mould.
