Abstract

The utility model provides a mechanism for releasing a steel cable cramp from a forging mould, which is composed of an upper mould, a lower mould, a lower mold base and a pushing column of the material releasing mechanism. The utility model has the following characteristics: the bottom of four column cavities in the cavities of the upper mould is respectively provided with a vertical through hole; a top rod in each through hole protrudes from the lower mould bottom; four top rods are positioned at a top tray in a bottom block of the lower mould; the lower surface of the top tray is provided with the material releasing column; the top tray is in a cylinder disc body shape.

Description

A kind of steel wire clamp forge mould knock-out gear

The utility model relates to a kind of mould emptier of forge mould, especially a kind of steel wire clamp forge mould knock-out gear.

Existing steel wire clamp forge mould knock-out gear is that the axis position that the liftout post directly withstands on die cavity ejects forging, the knock-out gear of this structure, and it is yielding to have a forging, the problem that four column material of forging are not full and mould damages easily.

The purpose of this utility model is exactly at the existing in prior technology problem, and forging can not be out of shape when a kind of depanning is provided, and four column shapes of forging are complete, and die life long steel wire clamp forge mould knock-out gear technical scheme.

For clearly demonstrating the technical characterstic of this programme, below by a specific embodiment, and in conjunction with its accompanying drawing, the utility model is elaborated.

Description of drawings:

Fig. 1 is the sectional structure schematic diagram of the utility model embodiment;

Fig. 2 is that the A-A of Fig. 1 is to schematic diagram;

Fig. 3 is that the B-B of Fig. 1 is to cross-sectional schematic.

By accompanying drawing as can be seen; the steel wire clamp forge mould knock-out gear of this programme is the liftout post 7 that patrix 2, counterdie 5, die shoe 1 and unloading mechanism are arranged; the characteristics of this programme are that the bottom surface in four post chambeies 4 in counterdie 5 die cavitys respectively has a vertical through hole; in each through hole, there is push rod 3 to stretch out the bottom surface of counterdie 5; four push rods 3 are located in taking over a business on 8 in the counterdie 5 bottom cushion blocks 6; take over a business 8 following then be the liftout post 7 of unloading mechanism, it is described that to take over a business 8 then be a cylinder plate body.

According to the description of such scheme as can be known since the bottom surface in four the post chambeies of this programme in die cavity each A vertical through hole is arranged, and push rod is arranged in each through hole, so the forging material of four columns of forging is forging The time be not subjected to air drag, therefore, the complete forging material of four columns of forging shape after forging is full to be enriched. And When forging demoulding, four push rods be withstand on die cavity four post chambeies below, that is to say, push rod The position is that therefore, the thrust that push rod makes progress when the demoulding just in time acts on below the post chamber of the most difficult demoulding Be difficult under the post chamber of the demoulding, and four push rods are upwards to push away simultaneously under the effect of taking over a business, so four Forging in the post chamber is the thrust that is subjected to simultaneously push rod, and therefore, forging can not produce distortion when the demoulding. And moving up and down of taking over a business is to lean on the liftout post of unloading mechanism to provide, and is again to move in cushion block, takes over a business Generally can not produce irregular movement. In addition, push rod is subjected to when forging below four post chambeies The pressure minimum that arrives, therefore, the jogger hole on the counterdie can not be out of shape by the pressure when forging, so big Prolonged greatly the life-span of mould. This shows that the utility model is to have essence compared with prior art The property characteristics and progressive, its implementation result also is apparent.

Claims

1. steel wire clamp forge mould knock-out gear; mainly contain the liftout post (7) of patrix (2), counterdie (5), die shoe (1) and unloading mechanism; respectively there is a vertical through hole bottom surface that it is characterized in that four the post chambeies (4) in counterdie (5) die cavity; in each through hole, there is push rod (3) to stretch out the bottom surface of counterdie (5); four push rods (3) are located in taking over a business on (8) in counterdie (5) the bottom cushion block (6), and taking over a business the following of (8) then is liftout post (7).

2. steel wire clamp forge mould knock-out gear according to claim 1 is characterized in that described to take over a business (8) be a cylinder plate body.
