Abstract

The invention relates to an injection mould with an auxiliary guide column. The injection mould comprises an A plate, a B plate, an A plate fixing assembly and a B plate fixing assembly, wherein the A plate is fixedly arranged on the A plate fixing assembly and the B plate is fixedly arranged on the B plate fixing assembly; when the mould is closed, the A plate is aligned to the B plate; the injection mould further comprises a guide column assembly; the guide column assembly is arranged in the A plate fixing assembly. Compared with the prior art, the injection mould with the auxiliary guide column has the advantages of high stability, high production efficiency, low maintenance cost and the like.

Description

A kind of injection mold with auxiliary guide pillar
Technical field
The present invention relates to a kind of injection mold, especially relate to a kind of injection mold with auxiliary guide pillar.
Background technology
At present, three template dies connect the important spare part of cover half A plate, water gap plate, I-shaped plate, for guide pillar, guide pin bushing, guide pillar, guide pin bushing are being played the part of considerable role in each secondary mould, for horizontal injection mould, guide pillar is cantilever beam, in engineering mechanics, say: cantilever beam just had very large sinking tendency originally, under the long-time load operation of A plate, 1., water gap plate can not draw away can make guide pillar, water gap plate be easy to certain distortion occurs, be mainly reflected in and in some three large-scale template die mould with pin point gate, just have following problem points:; 2., stub bar can not be got out; 3., manipulator gets not discharge head, causes after matched moulds, the material in runner damages and shortens the service life of mould again to mould, has affected production output, has increased the maintenance cost of mould.
Summary of the invention
Object of the present invention is exactly to provide in order to overcome the defect of above-mentioned prior art existence the injection mold with auxiliary guide pillar that a kind of stability is high, production efficiency is high, maintenance cost is low.
Object of the present invention can be achieved through the following technical solutions:
A kind of injection mold with auxiliary guide pillar, comprise A plate, B plate, A plate fixation kit and B plate fixation kit, described A plate is fixed on A plate fixation kit, described B plate is fixed on B plate fixation kit, during matched moulds, described A plate is aimed at B plate, it is characterized in that, described injection mold also comprises guide pillar assembly, and this guide pillar assembly is located in A plate fixation kit.
Described A plate fixation kit comprises I-shaped plate and water gap plate, and described water gap plate is fixed on I-shaped plate, and described A plate is fixed on water gap plate.
Described guide pillar assembly is provided with four.
Each guide pillar assembly comprises guide pillars and bushes, and described guide pillar is embedded in guide pin bushing through after I-shaped plate, and described guide pin bushing is located on water gap plate.
Between described guide pillar and guide pin bushing, be provided with gap.
Described B plate fixation kit comprises base plate, square iron, end needle plate and face needle plate, and described square iron, end needle plate are all fixed on base plate, and described face needle plate is fixed on end needle plate.
Compared with prior art, the present invention has the following advantages:
Four guide pillars that are fixed on I-shaped plate are short, and deformation coefficient is very little, the monolateral empty avoiding 0.3mm of guide pillar and guide pin bushing, reduce the friction between guide pillar and guide pin bushing, stripper plate has just more easily pulled open, and has improved the stability of mould, production output has also improved thereupon, has also reduced mold repair expense simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is Figure 1A portion partial enlarged drawing.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
Embodiment
As shown in Figure 1 and Figure 2, a kind of injection mold with auxiliary guide pillar, comprise A plate 3, B plate 4, A plate fixation kit and B plate fixation kit, described A plate 3 is fixed on A plate fixation kit, described B plate 4 is fixed on B plate fixation kit, and during matched moulds, described A plate 3 is aimed at B plate 4, described injection mold also comprises guide pillar assembly, and this guide pillar assembly is located in A plate fixation kit.Described A plate fixation kit comprises I-shaped plate 1 and water gap plate 2, and described water gap plate 2 is fixed on I-shaped plate 1, and described A plate 3 is fixed on water gap plate 2.
Described guide pillar assembly is provided with four.Each guide pillar assembly comprises guide pillar 9 and guide pin bushing 10, and described guide pillar 9 is embedded in guide pin bushing 10 through after I-shaped plate 1, and described guide pin bushing 10 is located on water gap plate 2, and described guide pillar 9 and the material of guide pin bushing 10 are SUJ2, and hardness is HRC60 ± 2.Between described guide pillar 9 and guide pin bushing 10, be provided with gap.Described B plate fixation kit comprises base plate 8, square iron 5, end needle plate 7 and face needle plate 6, and described square iron 5, end needle plate 7 are all fixed on base plate 8, and described face needle plate 6 is fixed on end needle plate 7.
In mould production process, injection moulding machine mould open drives A plate 3 by shutter, and A plate 3, after certain position, drives water gap plate 2 by guide pillar 9 again, and stub bar is thrown off.
