1. First of all, it is necessary to fully understand the technical requirements of the mold structure, material, hardness, precision and other aspects of the user, including whether the shrinkage of the formed plastic material is correct, whether the 3D dimensional modeling of the product is complete, and reasonable processing analysis.
2. The shrinkage cavity, flow mark, mold inclination, weld line and crack of the injection molding products are fully considered.
3. On the premise of not hindering the function and pattern of the injection parts, the processing method of the mold should be simplified as much as possible.
4. Whether the parting surface is suitable or not, the die processing, forming appearance and deburring of forming parts should be carefully selected.
5. Whether the pushing method is appropriate, whether the push rod, discharge plate, pushing sleeve or other methods are adopted, and whether the position of push rod and discharge plate is appropriate.
6. The side core pulling mechanism should be flexible and reliable.
7. Which method of temperature control is more suitable for plastic products, which structure circulation system is used for temperature control oil, temperature control water and coolant, and whether the size, number and location of coolant holes are appropriate.
8. The gate form, the size of the channel and the feed gate, the gate position and size are appropriate.
9. The influence of heat treatment deformation of various modules and die cores and whether the selection of standard parts is appropriate.
10. Whether the injection quantity, injection pressure and clamping force of injection molding machine are sufficient, whether the nozzle R and the hole diameter of gate sleeve match properly.
And so on these aspects of comprehensive analysis preparation, from the initial stage of product parts should be strictly controlled.
