Abstract
The utility model discloses a kind of semiclosed inner lock buckle molds of weld yoke forging, it mainly include upper die and lower die, preceding bridge portion, rear axle portion, lock, damping ditch, design has preceding bridge portion and rear axle portion in upper mold, preceding bridge portion and rear axle portion outer fix design lock, lower part of upper die matching design lower die, lower die increases in ear's die joint position has resistance ditch to slow down material outflow type chamber.The utility model can effectively reduce mismatch quality problems, improve stock utilization；Specifically, forging mismatch amount controls within 0.5mm from 1.0mm, and forging stock utilization is increased to 89% from 80%；Not only it had saved material drop originally, but also mismatch can be prevented.
Description
Technical field
The utility model relates to the fields of mold, and in particular to a kind of semiclosed inner lock buckle mold of weld yoke forging.
Background technique
The existing upper and lower mold of weld yoke forging is open architecture, this open architecture mold mainly due to equipment precision and
, on the one hand there are the biggish quality problems of mismatch, separately in bearing type die set guide pin and the factors such as guide sleeve cooperation precision influence and mold installation
One side stock utilization is lower.
Utility model content
The purpose of the utility model is to overcome the shortcomings of the prior art, and it is semiclosed to provide a kind of weld yoke forging
Inner lock buckle mold.
The purpose of this utility model is completed by following technical solution: this semiclosed inner lock buckle of weld yoke forging
Mold mainly includes upper die and lower die, preceding bridge portion, rear axle portion, lock, damping ditch, and design has preceding bridge portion and rear axle portion in upper mold,
Preceding bridge portion and rear axle portion outer fix design lock, and the lower die inner shape cooperates shackle designs.Lower part of upper die cooperation is set
In respect of lower die, lower die increases in ear's die joint position has resistance ditch to slow down material outflow type chamber.
There was only 0.2-0.3mm in gap after the upper die and lower die molding.
The utility model has the following beneficial effects:
1, the utility model can effectively reduce mismatch quality problems, improve stock utilization；Specifically, forging mismatch amount
From 1.0mm control within 0.5mm, forging stock utilization is increased to 89% from 80%；Increase in ear's die joint position and hinders
Power ditch slows down material outflow type chamber, so that semiclosed inner lock buckle mold be made not only to reach section material drop originally, but also can prevent the mesh of mismatch
's.
2, the utility model is designed in front and rear sides bridge portion outer fix and is latched, and the gap after upper/lower die molding only has
0.2-0.3mm, for upper and lower mould cavity positions because of the effect of lock, relative position only allows 0.2-0.3mm during forging in this way
Offset, thus make mismatch amount control within 0.5mm.

Description of symbols: upper mold 1, lower die 2, preceding bridge portion 3, rear axle portion 4, lock 5, damping ditch 6.
Specific embodiment
Detailed introduction is done to the utility model below in conjunction with attached drawing:
Embodiment: as shown in the picture, this semiclosed inner lock buckle mold of weld yoke forging, mainly include upper mold 1, lower die 2,
Preceding bridge portion 3, lock 5, damps ditch 6 at rear axle portion 4, and design has preceding bridge portion 3 and rear axle portion 4, preceding bridge portion 3 and rear axle portion 4 in upper mold 1
Outer fix designs lock 5, and 1 lower section matching design lower die 2 of upper mold, lower die 2 increases in ear's die joint position resistance ditch
6, slow down material outflow type chamber, to not only reach section material drop originally, but also the purpose of mismatch can be prevented.
There was only 0.2-0.3mm, in this way upper mold 1 and lower die during forging in gap after the upper mold 1 and lower die 2 mold
Because of the effect of lock 5, relative position only allows the offset of 0.2-0.3mm, makes the control of mismatch amount within 0.5mm cavity positions.
2 inner shape of lower die cooperation lock, 5 design.
It is understood that it will be understood by those skilled in the art that the technical solution of the utility model and utility model structure
Think of is subject to equivalent substitution or change all and should belong to the protection scope of the utility model the attached claims.
