The reasonable planning of automobile injection mold is the condition to ensure the smooth production of plastic products. Therefore, in order to avoid unnecessary waste of time and trouble during mass production, it is necessary to pay patience to adjust and control various processing conditions, find out the temperature and pressure conditions, and formulate standard automobile injection mold test procedures, which can be used to establish daily operation methods. As a planner who has been engaged in mold planning for many years, under the condition of fully understanding customers' products, what aspects should be included in order to fully control all links of mold planning?
1. First of all, we should fully understand the skill requirements of users in many aspects such as die structure, material, hardness and accuracy, including whether the shortening rate of formed plastic materials is correct, whether the 3D standard shape of the product is intact, and conduct reasonable processing and analysis.
2. Fully consider the shrinkage cavity, flow mark, mold pulling inclination, welding line, crack and other places that have an impact on the appearance of injection products.
3. Simplify the processing method of the mold as much as possible without hindering the product function and picture shape of the injection molded parts.
4. Whether the selection of parting surface is appropriate, careful selection should be made for die processing, forming appearance and deburring of formed parts.
5. Whether the pushing method is appropriate, whether the push rod, unloading plate, pushing sleeve and other methods are still other methods, and whether the orientation of the push rod and unloading plate is appropriate.
6. Whether the selection of core pulling arrangement on the surrounding surface is suitable, the action is flexible and reliable, and there should be no jamming.
7. What method is easy to use for temperature control, which structure is more suitable for plastic products, which structure is used for temperature control oil, temperature control water and coolant, and whether the size, quantity and orientation of coolant holes are appropriate.
8. Whether the gate mode, the size of material channel and feed port, and the gate orientation and size are appropriate.
9. The influence of heat treatment deformation of various modules and mold cores and whether the selection of standard parts is suitable.
10. Whether the injection quantity, injection pressure and clamping force of injection forming machinery are sufficient, and whether the nozzle R and gate sleeve aperture are suitable
