Precise forging die capable of achieving automatic side face pressing and vibration reduction

Abstract

The invention discloses a precise forging die capable of achieving automatic side face pressing and vibration reduction. The precise forging die comprises an upper die plate and a lower die plate, forging modules are arranged on the opposite faces of the upper die plate and the lower die plate, a supporting table is arranged at the bottom of the lower die plate, the supporting table is connected with a movable side plate through a limiting sliding assembly, a linkage cavity is formed in the movable side plate, the linkage cavity is slidably connected with an extrusion column, and a sealing assembly is arranged at the end of the extrusion column. A hydraulic device is used for driving an upper cover plate to move downwards, and a starting contact, a linkage rod, a control rod and a matching block are precisely and skillfully arranged on the upper cover plate, so that the forging modules, a central control plate and the upper cover plate can sequentially abut against one another, and therefore, a movable side cover can slowly move to the side walls of the forging modules to be fastened after the forging modules are closed, the movable side plate can move through cooperation of a side edge block and a triangular plate, the fastening force of the movable side cover on the forging modules can be enhanced through the movable side plate, the side face of the die is effectively pressed, and the strength of the die is guaranteed.

Description

technical field [0001] The invention relates to the technical field of mold sealing and fastening, in particular to a precision forging mold capable of side automatic compression and vibration reduction. Background technique [0002] Die forging refers to heating the metal first to become a liquid or softened state. Put it into the mold again, and form it at one time through the closing and closing of the upper and lower molds of the mold, sometimes requiring multiple times. The difference between it and casting is that casting is to pour heated molten metal directly into the model, while die forging also needs to pass the closing and closing of the upper and lower dies, and is subjected to extrusion force during the forming process, so the structure and structure of the die forging The mechanical properties are better than castings. [0003] The forging mold needs to have strong strength. For some special castings, the castings need to be pressurized. When the existing mo...

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the left and right supporting force between the molds is relatively small when the existing molds are used for high-pressure casting, so that after each mold clamping, a systematic operation is required to reinforce the sides of the molds to avoid side effects. The leakage of liquid metal caused accidents, which made the processing efficiency low, and the proposed precision forging die can be automatically compressed and damped on the side
