Description
Technical field
It the utility model is related to technical field of mold, more particularly to a kind of injection mold with secondary ejecting mechanism.
Background technology
In injection mold, in general shaping plastic only need to the once ejection action can demoulding, but special for shape
Product, it is necessary to product could successfully be departed from using secondary ejecting mechanism, conventional secondary ejecting mechanism has：（1）Splayed
Flap secondary ejecting mechanism, Angle Pin sliding block for secondary ejecting mechanism etc.；Such ejecting mechanism is complicated, and processing and manufacturing is difficult,
Size adjusting inconvenience is ejected, and its motion process has differential, and the scope used is also restrained.（2）The U-shaped secondary top of limit frame
Go out mechanism, drag hook secondary ejecting mechanism etc., though ejection is cumbersome without differential process, manufacture and adjustment ejection size.So
Traditional secondary ejecting mechanism, what is had is complicated, and manufacture is difficult；Although what is had is simple in construction, adjustment is inconvenient；Some machines
Structure is occurred with differential form during Double-ejection, it is difficult to meet the demands such as the simple and convenient of Making mold, strong applicability.
Utility model content
In order to overcome many disadvantages and deficiency of above-mentioned traditional secondary ejecting mechanism, the utility model provides a kind of structure letter
Single, the injection mold of convenient processing and manufacture is suitable to reach oblique top by controlling effective promotion stroke of the pushing block to push rod fixed block
The purpose that profit departs from from product, and do not produce movement interference with Double-ejection.
In order to solve the above technical problems, the utility model provides a kind of injection mold with secondary ejecting mechanism, bag
Mold base bottom plate is included, described mold base bottom plate is provided with pushing block guide rod, and pushing block guide rod is provided with pushing block, described pushing block respectively
Push rod fixed block is connected between inner side, is fixed on the outside of described pushing block on Ejector Retainer Plate, on described Ejector Retainer Plate on
Side is thimble panel, and the top of described pushing block guide rod is provided with B plates, push rod is fixed with described push rod fixed block, described
Push rod at the top of rear mold mold insert is installed, oblique top is installed, described oblique top bottom is provided with oblique top on described rear mold mold insert
Wear-resistant block.
As a preferable technical scheme of the present utility model, described pushing block guide rod curves inwardly in bottom, and
And it is oppositely arranged.
As a preferable technical scheme of the present utility model, KO is provided between described Ejector Retainer Plate and mold base bottom plate
Mold insert.
The one or more technical schemes provided in the embodiment of the present application, have at least the following technical effects or advantages：
The utility model mold movement is simple in construction, and shaped article is convenient in demoulding, and improves the Forming Quality of product, simultaneously
Mould structure is simplified, reduces Making mold difficulty and processing cost.

Embodiment
In order to be better understood from above-mentioned technical proposal, below in conjunction with Figure of description and specific embodiment to upper
Technical scheme is stated to be described in detail.
As Figure 1-Figure 4, a kind of injection mold with secondary ejecting mechanism described in the present embodiment, including mold base bottom
Plate 4, described mold base bottom plate 4 are provided with pushing block guide rod 6,8, and pushing block guide rod 6,8 is provided with pushing block 5,9 respectively, described
Pushing block 5,9 is connected with push rod fixed block 7 between inner side, and the outside of described pushing block 5,9 is fixed on Ejector Retainer Plate 3, described
Upside is thimble panel 2 on Ejector Retainer Plate 3, and the top of described pushing block guide rod 6,8 is provided with B plates 1, described push rod fixed block
Push rod 10,14 is fixed with 7, the top of described push rod 10,14 is provided with rear mold mold insert 12, pacified on described rear mold mold insert 12
Equipped with oblique top 11, the described bottom of oblique top 11 is provided with oblique top wear-resistant block 13.
Wherein, in the present embodiment, described pushing block guide rod 6,8 curves inwardly in bottom, and is oppositely arranged.
Wherein, in the present embodiment, KO mold inserts 15 are provided between described Ejector Retainer Plate 3 and mold base bottom plate 4.
Its operation principle is：
After mould die sinking, which acts, to be completed, rear mold ejecting mechanism present position is as shown in Fig. 2 K.O mold inserts（Such as Fig. 3 institutes
Show）Ejector retainner plate is promoted to move forward so that pushing block 5,9（As shown in Figure 2）Push rod is promoted to fix under the guide effect of guide rod 6
Block 7 travels forward, while mould mold insert 12 travels forward before the promotion of push rod 10,14, before oblique top wear-resistant block is fixed on mould mold insert 12,
Oblique top 11 is withstood to move obliquely, when pushing block 5,9 is moved at a, b two, pushing block no longer produces thrust to push rod fixed block 7,
Now oblique top 11 smoothly spins off from product, and ejector retainner plate continues to press on Double-ejection thimble and moved forward, when up to
To it is as shown in Figure 4 when, product is deviate from from mould completely.
It is described above, only it is preferred embodiment of the present utility model, not the utility model is made any formal
Limitation, although the utility model is disclosed above with preferred embodiment, but be not limited to the utility model, it is any ripe
Professional and technical personnel is known, is not being departed from the range of technical solutions of the utility model, when in the technology using the disclosure above
Hold the equivalent embodiment made a little change or be modified to equivalent variations, as long as being without departing from technical solutions of the utility model
Hold, any simple modification, equivalent change and modification made according to the technical essence of the utility model to above example, still
Belong in the range of technical solutions of the utility model.
