The so-called parting surface is to open the mold and take out the surface of the product. The choice of fractal surface is also the mold design, which is affected by many factors such as product shape, appearance, wall thickness, dimensional accuracy, and the number of holes. Whether the selection of the parting surface of the mold is reasonable is related to the life of the mold, the structure of the mold and the molding of the plastic parts, which are all very important links.
1. It is beneficial to the processing and manufacture of plastic mold inserts, inner molds or other molding parts. Conducive to plastic mold matching.
2. The parting surface of the plastic mold should be as simple as possible without skipping too much. If there are too many steps, not only the processing of injection mold parts is difficult, but also the difficulty of clamping the mold will be greatly increased.
3. It is beneficial to ensure the surface quality of plastic products, or to eliminate the bad defects of plastic products during the injection molding process. For example, different parting surfaces may lead to inconsistent wiring positions of injection molded products, especially the assembly requirements of electronic plastic molds are high.
4. In many cases, different parting surfaces may cause great changes in mold structure. Therefore, when selecting the parting surface of a plastic mold, the product requirements should be met, and the parting surface of the mold structure should be optimized first.
5. It is beneficial to the molding of plastic products, which is the most basic requirement. If the selection of the classification surface of the plastic mold is unreasonable, it may cause the plastic product to be inverted and unable to be formed.
