What are the factors that affect the precision mold processing structure?

1. Cavity layout. According to the geometric characteristics of plastic parts, dimensional accuracy requirements, batch size, ease of mold making, mold cost, etc. to determine the number of cavity and its arrangement.

2. Determine the parting surface. The location of the parting surface should be conducive to mold processing, venting, stripping and forming operations, and the surface quality of plastic parts.

3. Determine the gating system (shape, position, size of the main sprue, branch runner, and gate) and the exhaust system (exhaust method, exhaust slot location, size).

4. Select the ejector method (jack, pipe jacking, push plate, combined ejector) to determine the undercut handling method and core withdrawal method.

5. Determine the cooling, heating method, heating and cooling groove shape, position, and heating element mounting location.

6. According to the mold material, strength calculation or empirical data, determine the mold parts thickness and dimensions, shape structure and all connections, positioning, guide position.

7. Determine the structure of the main molded parts and structural parts.

8. Consider the strength of various parts of the mold and calculate the working dimensions of the molded parts.

If these problems are solved, the structure of the mold will naturally be solved. At this point, you should start sketching the mold structure to prepare for the formal drawing.
