Because the market demand for molds and mold products is very different, there are many types, and there are great changes in shape, size, material, structure, etc., so high requirements are placed on the production of molds and products. , and how to effectively control the size of plastic precision injection molds is the first problem we must solve.

1. First of all, it is necessary to have a full understanding of the user's technical requirements in terms of structure, material, hardness, and precision of plastic injection molds, including whether the shrinkage of the formed plastic parts is correct, whether the three-dimensional shape of the product is complete, and whether the processing is reasonable.

2. For the parts that have an impact on the appearance, such as shrinkage holes, flow marks, mold drafts, weld lines and cracks, injection products should be fully considered.

3. On the premise of not affecting the function and pattern of injection products, simplify the processing method of plastic precision injection molds as much as possible.

4. Whether the selection of the parting surface is appropriate, and whether the mold processing, molding appearance and deburring of the molding parts are cautious.

5. Whether the ejection method of the plastic precision injection mold is appropriate, whether the ejector, ejector, ejector sleeve, etc. are used or other methods, and whether the position of the ejector and the ejector is appropriate.

6. Whether the core-pulling mechanism on the side of the plastic precision injection mold is appropriate, and whether the action is flexible and reliable, it should be ensured that there is no sticking phenomenon.

7. What method of mold temperature control is suitable for plastic products, what structure annular system is used for coolant, whether the size, number, and location of coolant holes are appropriate, etc.

8. The gate form, the size of the forehearth and the feed port, and whether the gate location and size are appropriate.

9. The influence of heat treatment deformation of various components and mold cores and whether the selection of standard parts is appropriate.

10. Whether the injection volume, injection pressure and clamping force of the injection molding machine are sufficient, whether the injection port R and the size of the gate sleeve match.
