What factors will affect the structure of precision mould processing?
With the development of science and technology and the wide application of precision mould, what are the factors that affect the structure of precision mould processing
1. Determine the parting surface.The position of the parting surface should be conducive to mold processing, exhaust, demoulding and molding operation, plastic surface quality.
2. Cavity layout.According to the geometric structure of plastic parts, dimensional accuracy requirements, volume size, difficult to manufacture mold, mold cost, etc.
3. Determine the shape, location and size of the pouring system (main runner, runner and gate) and the exhaust system (method of exhaust, position and size of vent).
4. Select the jacking method (jacking rod, jacking pipe, pushing plate and combined jacking), and decide the side concave treatment method and core pulling method.
5. Determine the shape, location and installation location of the heating and cooling groove.
6. According to the mold material, strength calculation or empirical data, determine the mold part thickness and external dimension, external structure and the position of all connecting, positioning and guiding parts.
7. Determine the structural form of main molded parts and structural parts.
8. Taking into account the strength of each part of the mold, calculate the working size of the formed part.
If these problems can be solved, the mold structure can be successfully solved.At this time, we should start to sketch the mold structure and prepare for the formal drawing.
