Abstract

The present invention relates to the field of powder forming mold technology and discloses a powder metallurgy compressor connecting rod forming mold, comprising an upper template and a lower template. An installation plate is fixedly connected to the side wall of the lower template, and a through-hole groove is opened in the center of the lower template. The present invention addresses the problem that the concave position of the outer wall of the connecting rod increases the demolding resistance. A power mechanism and a buckle mechanism are provided inside the equipment When the template drives the lower mold to slide downwards, the cylinder will not move downwards synchronously due to significant resistance. At this time, the outer wall of the finished product will detach from the top of the lower mold, and the outer wall of the finished product will only be in contact with the top planes of the two cylinders. When the top height of the lower mold moves downwards below the top of the lower template, the finished product will be at the top of the cylinder. With the lateral movement of the feeding cart, the finished product will be pushed away from the outer wall of the cylinder, effectively reducing the demolding resistance of the concave or protruding position inside the mold to the finished product.
