AI Technical Summary
After being heated to high temperatures, the pressure ring forging is prone to sticking to the lower mold and is difficult to remove.
A composite mold tooling for making pressure ring forging blanks was designed. By coordinating the movement of the push rod and the lifting rod, a gap is created in the inner wall of the pressure ring forging. The elastic force of the spring is used to support the pressure ring forging with the inner support plate, so that it can be loosened from the mold.
It effectively prevents the pressure ring forging from sticking to the mold at high temperatures, making it easy to remove.
