Improved die with automatic stripping function

Abstract

The invention discloses an improved die with an automatic stripping function. The improved die with the automatic stripping function comprises an upper frame body and a lower frame body arranged below the upper frame body. A pressing plate, an upper die body and a lifting push rod are arranged in the upper frame body. Oblique-surface pushing and pressing columns which extend downwards are fixedly arranged on the two sides of the pressing plate correspondingly. A lower die body which is opposite to the upper die body is arranged at the top of the lower frame body. Through holes are formed in the positions, opposite to the lower portions of the oblique-surface pushing and pressing columns, in the lower frame body. Sliding grooves are formed in the portion, between the through holes, in the lower frame body in a bilaterally symmetrical mode. A partition plate which is fixedly connected with the lower frame body is arranged between the sliding grooves. A through hole which penetrates through the wall of the lower frame body and communicates with the bottom of the interior of the lower die body is formed in the top of each sliding groove, and an oblique-surface stripping block is arranged in the through hole. A sliding guide groove is formed in the bottom of each sliding groove, a sliding block is slidably arranged in each sliding groove, an ejection spring is arranged between each sliding block and the partition plate, and an oblique-surface sliding groove is formed in the top of each sliding block. The improved die with the automatic stripping function is simple in structure, and automatic stripping can be achieved after punching is completed; and the manufacturing cost is low, and maintenance is convenient.

Description

technical field [0001] The invention relates to the technical field of molds, in particular to an improved automatic stripping mold. Background technique [0002] Stamping processing in mechanical processing occupies an important position in the processing industry of the national economy. The stamping process is adopted, which has the advantages of high precision, high efficiency, good quality, material saving and low cost. Stamping die is an indispensable process equipment for stamping production, and it is a technology-intensive product. The quality, production efficiency and production cost of stamping parts are directly related to the design and manufacture of molds. When the contact area between the upper and lower dies and the parts of the existing stamping die is relatively large, it is easy for the parts to stick to the die and not easy to fall off. Manual detachment is required, the operation is dangerous and the processing efficiency of the parts is low. In addi...

AI Technical Summary

Problems solved by technology

When the contact area between the upper and lower dies and the parts of the existing stamping die is relatively large, it is easy for the parts to stick to the die and not easy to fall off. Manual detachment is required, the operation is dangerous and the processing efficiency of the parts is low. In addition, the existing The automatic stripping mold needs to use a separate stripping mechanism for stripping work, which has problems such as low work efficiency, high manufacturing cost, and high maintenance cost.
