Transversal perforating die for inner layer of the refrigerator door

Abstract

The invention discloses a transverse punching die for a refrigerator door liner, which comprises an upper moulding board and a lower moulding board which are matched mutually to fix the refrigerator door liner. A punching mechanism is arranged on the upper moulding board, and the punching mechanism consists of a press plate arranged on the upper part of the upper moulding board and a plurality ofpunching units connected with the press plate. Each punching unit comprises a sliding chute block, a slide block, a connecting slide block, a press plate and a connecting rod, wherein the sliding chute block is fixed on the bottom of the upper moulding board; the slide block is slidingly arranged on the sliding chute block and is provided with a punching pin; and the connecting rod can transfer the lengthwise movement of the press plate into the transverse movement of the slide block. Because of adopting the design of the slide block and the connecting rod, the punching die has the advantagesof simple integral structure, fewer parts and components, low manufacture and maintenance cost, and convenient assembly and operation in use, can reduce work hours and workload of workers and can improve the production efficiency.

Description

technical field [0001] The invention relates to a horizontal punching die for a refrigerator door liner. Background technique [0002] At present, since there is no special horizontal punching die for the refrigerator door liner, the processing of the side holes of the refrigerator door liner is done in multiple times by using multiple conventional punching dies. The process is cumbersome, resulting in low processing efficiency. At the same time, the existing conventional punching dies for processing the side holes of the refrigerator door liner are not only complex in structure, but also often require hydraulic or pneumatic equipment to drive and operate, and the manufacturing and maintenance costs are also high. Contents of the invention [0003] The purpose of the present invention is to provide a horizontal punching die for refrigerator door panels, which is specially used for processing the side holes of refrigerator door panels, and has a simple structure and low man...

Problems solved by technology

[0002] At present, there is no special horizontal punching die for the refrigerator door liner, so the processing of the side holes of the refrigerator door liner is completed in multiple times by using multiple conventional punching dies. The process is cumbersome, resulting in low processing efficiency.

At the same time, the existing conventional punching dies used to process the side holes of the refrigerator door liner are not only complex in structure, but also often require hydraulic or pneumatic equipment to drive the operation, and the manufacturing and maintenance costs are also high.
