Refrigerator door inner container punching die positioning structure

Abstract

The invention relates to the technical field of refrigerator inner container forming, and discloses a refrigerator door inner container punching die positioning structure which comprises a feeding positioning mechanism. The feeding positioning mechanism comprises a base, and a lifting guide column is arranged at the top of the base. According to the refrigerator door inner container punching die positioning structure, a punching belt wheel drives a primary cam and a secondary cam to rotate, the primary cam drives a primary sliding plate to move downwards, the primary sliding plate drives a primary punching frame to move downwards, the primary punching frame drives a shaping die to move downwards, the shaping die conducts primary punching forming on a plate, the secondary cam drives a secondary sliding plate to move downwards, the secondary sliding plate drives a secondary punching frame to move downwards, the secondary punching frame drives a secondary die and a rotating sleeve to move downwards, and the rotating sleeve makes contact with a limiting rod, so that the effects that secondary stamping forming is achieved, the pulling stress of the plate is reduced, the plate is prevented from being broken, the plate can be rapidly stamped and formed, and a formed inner container is automatically separated from the die are achieved.

Description

technical field [0001] The invention relates to the technical field of refrigerator liner molding, in particular to a positioning structure for a punching die for a refrigerator door liner. Background technique [0002] The inner liner of the refrigerator door cooperates with each other to ensure that the temperature of the refrigerator will not be lost and the cooling effect of the refrigerator is ensured. , The liner needs to be made of steel, which makes the liner unable to be processed by ordinary processing methods, and stamping has become its preferred processing method. However, in the stamping process, it is often encountered that the feeding speed is slow, and manual participation is more, which is easy to cause stamping errors. During the stamping and forming process of the plate, the plate is broken and the product is difficult to leave the mold, etc., causing great damage to the manufacturer. loss. [0003] Therefore, in view of these problems, we need a positi...
