Abstract

The utility model discloses a forging die. The forging die comprises an upper die and a lower die. The lower die is placed on a base plate, the lower die is provided with a three-stage step hole which gradually becomes thin from top to bottom along the central axis, the base plate is provided with a two-stage step hole which gradually becomes thin from top to bottom along the central axis, a second ejector rod and a first ejector rod are arranged inside a first stage step of the two-stage step hole of the base plate and a third stage step of the three-stage step hole of the lower die respectively, the periphery of the bottom of the lower die is provided with a convex edge outwards, a compression plate is arranged on the lower die in a sleeved mode and the compression plate is pressed on the convex edge of the lower die. Due to the fact that the ejector rods are used for conducting demoulding, production efficiency is high, the amount of equipment staff is small and materials are saved.

Description

A kind of forging mold
Technical field
The utility model relates generally to the forging field, relates in particular to a kind of forging mold.
Background technology
This forging mold of prior art is laterally to forge, and needs heating-jumping-up-pressure side-die forging-side cut-correction 6 procedures, makes now endways closed-die forging into, it is just passable that technique makes heating-die forging into, reduce raw material approximately 20%, production efficiency improves, and the equipment personnel reduce.
The utility model content
The utility model purpose is exactly in order to remedy the defective of prior art, provides that a kind of production efficiency is high, the equipment personnel are few, the forging mold of economical with materials.
The utility model is achieved through the following technical solutions:
A kind of forging mold, it is characterized in that: include upper die and lower die, described counterdie places on the backing plate, described counterdie has from top to bottom three grades of gradually thin stepped holes along the axis, backing plate has from top to bottom gradually thin two-stage stepped hole along the axis, be equipped with respectively push rod two, push rod one in the first order of the two-stage stepped hole of backing plate and in the third level of the stepped hole of counterdie, the outer, bottom of counterdie outwards is provided with the convex edge, is set with a pressing plate on the counterdie and is pressed on the convex edge of counterdie.
Described a kind of forging mold is characterized in that: described pressing plate is provided with a plurality of screwed holes along circumference, and backing plate is provided with and the corresponding screwed hole of the screwed hole of pressing plate, and pressing plate is fixed on counterdie on the backing plate by screw.
Described a kind of forging mold is characterized in that: the protuberance of described patrix is pressed in the first order of stepped hole of counterdie.
Described a kind of forging mold is characterized in that: the diameter of described push rod two is less than the internal diameter of the first order in the two stage steps hole of backing plate, greater than the internal diameter of the second level in the two stage steps hole of backing plate.
The utility model has the advantages that:
The utility model carries out the demoulding by two push rods, and production efficiency is high, the equipment personnel are few, economical with materials.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the top view of backing plate.
Fig. 3 is the top view of pressing plate.
The specific embodiment
As shown in Figure 1, 2, 3, a kind of forging mold, include patrix 1, counterdie 2, counterdie 2 places on the backing plate 6, counterdie 2 has from top to bottom three grades of gradually thin stepped holes along the axis, backing plate 6 has from top to bottom gradually thin two-stage stepped hole along the axis, be equipped with respectively push rod 5, push rod 4 in the first order of the two-stage stepped hole of backing plate 6 and in the third level of the stepped hole of counterdie, the outer, bottom of counterdie 2 outwards is provided with convex edge 8, is set with a pressing plate 4 on the counterdie 2 and is pressed on the convex edge 8 of counterdie 2.
Pressing plate 4 is provided with a plurality of screwed holes along circumference, and backing plate 6 is provided with and the corresponding screwed hole of the screwed hole of pressing plate 4, and pressing plate 4 is fixed on counterdie 2 on the backing plate 6 by screw 7.
The protuberance of patrix 1 is pressed in the first order of stepped hole of counterdie 2.
The diameter of push rod 5 is less than the internal diameter of the first order in the two stage steps hole of backing plate 6, greater than the internal diameter of the second level in the two stage steps hole of backing plate 6.
