Mold for production of metal C-shaped sealing ring

Abstract

The invention discloses a mold for production of a metal C-shaped sealing ring, and relates to the technical field of processing of molds. The mold comprises a fixed mold holder plate, a moving mold holder plate, a fixed mold assembly and a moving mold assembly, wherein the fixed mold assembly comprises a first mold plate and a second mold plate; the bottom surfaces of the first mold plate and second mold plate are in slide fit with the top surface of the fixed mold holder plate; the surfaces of the first mold plate and second mold plate are respectively provided with an arc-shaped groove opening. The mold has the advantages that under the cooperation function of an electric push rod, an extruding block, a slide column, a slope, a penetrating groove opening, a slide ring, an extruding casing, an extruding ring and the arc-shaped groove openings, one part of an annular blank is extruded into a concave structure; under the cooperation function of a pull spring and a motor, the other positions of the annular blank are extruded again; by arranging the first mold plate, the second mold plate and a telescopic rod, the processed blank can be conveniently placed and fetched, so as to solvethe problems of failure in one-time forming and inconvenience in placing and fetching in the existing mold for the production of the metal C-shaped sealing ring.

Description

technical field [0001] The invention belongs to the technical field of mold processing, in particular to a mold for producing a metal C-shaped sealing ring. Background technique [0002] Mold processing refers to the processing of forming and billet tools, and also includes shearing dies and die-cutting dies. Usually, the die is composed of an upper die and a lower die. The steel plate is placed between the upper and lower dies. The forming of the material is realized under the action. When the press is opened, the workpiece determined by the shape of the mold will be obtained or the corresponding waste will be removed. The workpieces as small as electronic connectors and as large as automobile dashboards can be molded and molded. The process includes: cutting die, punching die, composite die, extrusion die, four slide rail die, progressive die, stamping die and die-cutting die, etc. [0003] The inner side of the traditional metal C-shaped sealing ring is concave, which ca...

Problems solved by technology

[0004] The object of the present invention is to provide a mold for the production of metal C-shaped sealing rings, through electric push rods, extrusion blocks, sliding columns, slopes, through notches, sliding rings, extrusion shells, extrusion rings and arc-shaped notches The combined use of the ring blank is used to extrude a part of the ring blank into a concave structure, and the other position of the ring blank is squeezed again through the cooperation of the tension spring and the motor. The processing of the blank is facilitated by the first template, the second template and the telescopic rod. Unloading and retrieving materials, which solves the problem that the existing metal C-shaped sealing ring production mold cannot be formed at one time and is not convenient for discharging and retrieving materials.
