AI Technical Summary
In existing injection molding machines, the outlet of the injection main pipe is connected to the feed port of the lower mold, which makes the lower mold unable to move. After the product cools and solidifies, it sticks tightly to the inner wall of the lower mold, making demolding difficult and causing uneven stress on the product, which is easy to damage.
The top plate is slidably connected inside the lower mold, and a sleeve is fitted at the end of the injection main pipe. The feed port of the top plate is connected to the sleeve, and the product is ejected through the top plate, making the product easy to demold.
The design of the top plate and sleeve simplifies the demolding process, reduces the risk of product damage, and improves the convenience and uniformity of demolding.
