AI Technical Summary

Technical Problem

The transverse side hole design of existing injection molds results in the large size of the mold and the long stroke of the road. The product is unevenly subjected to force before ejection, which is prone to deformation.

Method used

Design an injection mold that can be ejected in a secondary transverse direction. Through the coordination of the upper mold cavity and the lower mold cavity, combined with the mold core, oil cylinder, push plate and push rod, the integration of the line position and the ejection structure is achieved. Reduce extra-long stroke on the side.

Benefits of technology

The overall size of the mold is miniaturized, mass production is used with a smaller machine, and the excessively long stroke on the side is avoided, ensuring that the product is subjected to uniform stress during the ejection process and reducing the risk of deformation.
