Upper die locking and closing mechanism for large die frame

Abstract

The invention discloses an upper die locking and closing mechanism for a large die frame. The mechanism comprises an upper die frame, a lower die frame and an upper die, wherein the upper die is fixedto the upper die frame through an upper die fixing block and an upper die locking assembly; a die closing locking assembly is arranged at the front end of the upper die frame; a die closing fitting assembly, which is a transversely-arranged cylindrical structure, is arranged on the lower die frame; when the upper die is to be mounted, the upper die is primarily fixed through the upper die fixingblock, and then two wedge-shaped blocks fit a dovetail groove in the upper die to further lock the upper die; the operation is simple; the lower die can be conveniently mounted and dismounted; in addition, the structure is stable, and the upper die is prevented from separating; when in die closing, a lower hoisting arm is driven to lift through a lifting driving cylinder on an upper hoisting arm,and an upper overturning cover fits the die closing fitting part and is controlled to overturn through an upper overturning motor, thus finishing the die closing action; the die closing process is automatically carried out without manual operation, so that the processing efficiency is improved, and the die closing stability is ensured.

Description

technical field [0001] The invention relates to an upper mold locking and clamping mechanism of a large mold frame. Background technique [0002] The mold base is the support mechanism of the mould, and it is an indispensable tool for modern industrial production; among them, the mold base for automobile tool processing is a large mold base, which is used to support the mold for manufacturing automobile products, and control the mold closing and opening; the existing Most of the automotive tool processing mold bases are relatively simple, and the molds are welded on the mold base and cannot be replaced; the mold base generally only has the function of opening and closing, the degree of automation is low, the operation is inconvenient, and it is not conducive to improving the processing efficiency, and the accuracy is poor. Cause the defective product rate to be higher; Therefore, now need to design a kind of large-scale automobile tool formwork for above-mentioned deficiency...

[0002] The mold base is the support mechanism of the mould, and it is an indispensable tool for modern industrial production; among them, the mold base for automobile tool processing is a large mold base, which is used to support the mold for manufacturing automobile products, and control the mold closing and opening; the existing Most of the automotive tool processing mold bases are relatively simple, and the molds are welded on the mold base and cannot be replaced; the mold base generally only has the function of opening and closing, the degree of automation is low, the operation is inconvenient, and it is not conducive to improving the processing efficiency, and the accuracy is poor. This leads to a high rate of defective products; therefore, it is now necessary to design a large-scale automotive tool mold base for the above-mentioned shortcomings, and to design its upper mold locking mold clamping mechanism
