A Mold Opening Mechanism with Mechanical Gain

Abstract

A mold opening mechanism with mechanical gain, including a base, a static mold mounting plate arranged on the base, a dynamic mold mounting plate matched with the static mold mounting plate, and used to drive the dynamic mold mounting plate to move back and forth to realize opening / closing The transmission mechanism of the mold action; the transmission mechanism includes a screw, a nut set outside the screw, a connecting rod, and a hand wheel mounted on the end of the screw, and the connecting rod is articulated between the movable mold mounting plate and the nut. Compared with the prior art, the present invention overcomes the phenomenon of wrong shape and model damage that are easy to occur when opening and closing the mold manually. The present invention has simple structure, low manufacturing cost and wide application range; adopts screw drive, and the movement of the mechanism is accurate and reliable. The mold clamping force is large, which will not cause the mold to bulge and run out of fire; the operation is convenient, and the mold opening and closing process can be realized only by turning the hand wheel, reducing labor intensity. The invention prolongs the service life of the mold. The operation time of opening and closing the mold is short, which improves the production efficiency of the product.

Description

technical field [0001] The invention relates to a mold opening mechanism with mechanical gain. Background technique [0002] In many auto parts manufacturing enterprises, there are many casting manual molds, which are used for single-piece small batch production or casting production of products with small volume and weight. The opening and closing process of the traditional manual mold is completed by the casting worker manually opening and closing the dynamic and static mold, which is labor-intensive, low in production efficiency, and the process of opening and closing the mold is unstable; It is easy to bulge and run out during the pouring process, and the mold clamp is easy to be deformed and damaged after long-term use, and needs to be replaced frequently. Part of the process, such as pouring, mold closing, and mold opening, cannot be controlled accurately and reliably like machining, and can only be controlled by the operator's experience, so it is easy to cause low c...

Problems solved by technology

The opening and closing process of the traditional manual mold is completed by the foundry worker manually opening and closing the dynamic and static mold, which is labor intensive, low in production efficiency, and the process of opening and closing the mold is unstable; It is easy to bulge and run out during the pouring process, and the mold clamp is easy to deform and damage after long-term use, and needs to be replaced frequently

Some processes, such as pouring, mold closing, and mold opening, cannot be controlled accurately and reliably like mechanical processing, and can only be grasped by the operator's experience, so it is easy to cause low casting yield and unstable product quality
