Description

Injection Water Cup Mould Plastic Mould

   Because the product's cup mouth does not allow any burrs, the product's demoulding form is very important. There are generally three forms: scraper demoulding, blowing demoulding, and middle ejection. I have tried two methods of scraper demoulding and air blow demoulding before. After long-term use, the effect is not very good. Although the scraper demoulding is simple, but the mold mouth will appear burrs after using the mold for a period of time. Blowing and demoulding is also feasible, but in cooperation with the robot, there will be a difference in rhythm due to changes in air pressure, which makes the robot often alarm, so the middle ejection method is adopted

The dimensional accuracy of plastic parts refers to the degree of conformity between the dimensions of the plastic parts obtained after molding and the dimensions in the drawings. Generally speaking, the dimensional accuracy of plastic parts depends on the range of plastic shrinkage caused by the material and process conditions, the accuracy of mold manufacturing, the degree of wear of cavity cores, and process control factors. And some structural features of the mold affect the dimensional accuracy of the plastic parts to a considerable extent. Therefore, the precision of plastic parts should be selected as low as possible.

Plastic products are increasingly popular in industry because of their advantages of small density and light weight, and there is a trend of "placing steel with plastic". Plastic molds can meet the processing requirements and usage requirements of plastics, and can well reduce the production cost of plastic products. The quality of plastic depends on the correct structure of the mold and the correct shape of the molded parts of the mold, and the precise size and low surface roughness to ensure.
