Description
Technical field
The present invention relates to technical field of mold, particularly relate to a kind of from ejection die.
Background technology
The dust seal of button, suspension drag link and the waterproof need of sealing and dustproof of rocking arm junction bulb on automobile
Hat shape dust cover to be used.Above-mentioned dust cover is as preventing dust and muddy water entrance button interior and suspension joint
Internal guard member, once inefficacy can aggravate the electronic product damage of button interior and cause suspending joint life
Rust, brings hidden danger for traffic safety.This type of dust cover structure is simple, it is desirable to production cost is relatively low.Existing skill
In art, the mould of use, when goods take out, needs special ejecting mechanism to eject, and causes producing effect
Rate is the highest, affects the control of production cost.
Summary of the invention
In order to solve technical problem present in background technology, the present invention proposes a kind of from ejection die, its
Production efficiency is high, and product takes out easily.
The present invention propose one from ejection die, be used for being molded dust cover, including cope match-plate pattern, middle template,
Lower bolster, backing plate, core rod and arm-tie, core rod is arranged in middle template, cope match-plate pattern, middle template, lower bolster
The die cavity being correspondingly arranged is collectively forming multiple die cavity, and each die cavity includes multiple submodule chamber and a cast chamber,
Each submodule chamber all connect with cast chamber, and cast chamber has sprue gate, under backing plate is positioned at below lower bolster and is close
Template one side have accommodate arm-tie groove, arm-tie is positioned in above-mentioned groove, core rod by multiple corresponding to submodule
The submodule core composition in chamber, core rod forms dust cover forming cavity with die cavity, and submodule core has push rod, above-mentioned push rod
One end is resisted against on arm-tie, and the other end is against cope match-plate pattern and runs through lower bolster.
Preferably, the quantity of each die cavity neutron die cavity is six, and six hexagonal distributions of sub-die cavity are enclosed
Around cast chamber.
In the present invention, sizing material is poured into cast chamber by sprue gate, owing to submodule chamber is connected with cast chamber,
Such that it is able to realize pouring in multiple submodule chamber by sizing material, production efficiency is high；When, after rubber vulcanization, producing
During product take out, owing to core rod is made up of the submodule core corresponding to submodule chamber, submodule core can be the most only
The vertical motion carrying out vertical direction, meanwhile, submodule core has push rod, pulls out arm-tie, such that it is able to eject son
Core rod, the most only need to make middle template decline, and just can easily be taken out by product, and depanning efficiency is high.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation from ejection die that the present invention proposes；
Fig. 2 is a kind of sectional view from ejection die that the present invention proposes.
Detailed description of the invention
As depicted in figs. 1 and 2, Fig. 1 is a kind of structural representation from ejection die that the present invention proposes；
Fig. 2 is a kind of sectional view from ejection die that the present invention proposes.
See figures.1.and.2, the present invention propose one from ejection die, be used for being molded dust cover, including on
Template 1, middle template 2, lower bolster 3, backing plate 6, core rod and arm-tie 5, core rod is arranged in middle template 2,
The die cavity that cope match-plate pattern 1, middle template 2, lower bolster 3 are correspondingly arranged is collectively forming multiple die cavity, each die cavity bag
Include 6 sub-die cavitys 8 and a cast sub-hexagonal distribution of die cavity 8 in 7,6, chamber around pouring into a mould chamber 7, respectively
Submodule chamber 8 all connects with cast chamber 7, and cast chamber 7 has sprue gate, and backing plate 6 is positioned at below lower bolster 3
And near lower bolster 3 one side have accommodate arm-tie 5 groove, arm-tie 5 is positioned in above-mentioned groove, core rod by
Multiple submodule cores 4 corresponding to submodule chamber 8 form, and core rod forms dust cover forming cavity, submodule core 4 with die cavity
Having push rod, above-mentioned push rod one end is resisted against on arm-tie 5, and the other end is against cope match-plate pattern 1 and runs through lower bolster 3.
In the present embodiment, sizing material is poured into cast chamber 7 by sprue gate, due to submodule chamber 8 and cast chamber 7
Being connected, such that it is able to realize pouring in multiple submodule chamber 8 by sizing material, production efficiency is high；Work as rubber vulcanization
After, during product is taken out, owing to core rod is made up of the submodule core 4 corresponding to submodule chamber 8, son
Core rod 4 can carry out the motion of vertical direction independently of one another, and meanwhile, submodule core 4 has push rod, and pull-out is drawn
Plate 5, such that it is able to eject submodule core 4, the most only need to make middle template 2 decline, and just can easily be taken out by product,
Depanning efficiency is high.
The above, the only present invention preferably detailed description of the invention, but protection scope of the present invention not office
Being limited to this, any those familiar with the art is in the technical scope that the invention discloses, according to this
The technical scheme of invention and inventive concept thereof in addition equivalent or change, all should contain the protection in the present invention
Within the scope of.
