Abstract
The invention discloses an automatic ejection die used for forming a dust shield. The automatic ejection die includes an upper die plate, a middle die plate, a lower die plate, a base plate, a die core and a pulling plate, the die core is arranged on the middle die plate, cavities arranged corresponding to the upper die plate, the middle die plate and the lower die plate form a plurality of die cavities, each of the die cavities comprises a plurality of subsidiary die cavities and a casting cavity, each of the subsidiary die cavities is connected with the casting cavity, the casting cavity has a sprue gate, the base plate is positioned below the lower die plate, one surface of the base plate close to the lower die plate is provided with a groove for accommodating the pulling plate, the pulling plate is positioned in the groove, the die core is composed of subsidiary die cores corresponding to the subsidiary die cavities, the die core and the die cavity form a dust shield molding cavity, each of the subsidiary die cores has an ejection rod, one end of the ejection rod depends on the pulling plate, and the other end of the ejection rod depends on the upper die plate and penetrates through the lower die plate. The automatic ejection die has the advantages of high production efficiency, and easy removal of a product molded in the die.
Description
Technical field
The present invention relates to technical field of mold, particularly relate to a kind of from ejection die.
Background technology
On automobile, the dust seal of button, suspension drag link and the sealing and dustproof waterproof of rocking arm junction bulb need to use hat shape dust cover.Above-mentioned dust cover is as the guard member preventing dust and muddy water from entering button interior and suspension joint inside, once the electronic product that inefficacy can aggravate button interior damages and causes suspension joint to be got rusty, for traffic safety brings hidden danger.This type of dust cover structure is simple, requires that production cost is lower.In prior art, the mould of use, when goods take out, needs special ejecting mechanism to eject, and causes production efficiency not high, affects the control of production cost.
Summary of the invention
In order to solve the technical problem existed in background technology, the present invention proposes one from ejection die, its production efficiency is high, and product takes out easily.
The one that the present invention proposes is from ejection die, for shaping dust cover, comprise 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, the die cavity that lower bolster correspondence is arranged forms multiple die cavity jointly, each die cavity comprises multiple submodule chamber and a cast chamber, each submodule chamber is all communicated with cast chamber, cast chamber has sprue gate, backing plate to be positioned at below lower bolster and to have near lower bolster one side the groove holding arm-tie, arm-tie is arranged in above-mentioned groove, core rod is made up of multiple submodule core corresponding to submodule chamber, core rod and die cavity form dust cover forming cavity, submodule core has push rod, above-mentioned push rod one end is resisted against on arm-tie, the other end is against cope match-plate pattern and run through lower bolster.
Preferably, the quantity of each die cavity neutron die cavity is six, and six sub-die cavitys are that hexagon distribution is around cast chamber.
In the present invention, sizing material is poured into cast chamber by sprue gate, because submodule chamber is connected with cast chamber, thus can realize being poured into by sizing material in multiple submodule chamber, production efficiency is high; When after rubber vulcanization, in the process that product is taken out, because core rod is made up of the submodule core corresponding to submodule chamber, submodule core can carry out the motion of vertical direction independently of one another, simultaneously, submodule core has push rod, pull-out arm-tie, thus submodule core can be ejected, now only middle template need be made to decline, just can easily be taken out by product, 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 one that the present invention proposes is from ejection die, for shaping dust cover, comprise cope match-plate pattern 1, middle template 2, lower bolster 3, backing plate 6, core rod and arm-tie 5, core rod is arranged in middle template 2, cope match-plate pattern 1, middle template 2, the die cavity that lower bolster 3 correspondence is arranged forms multiple die cavity jointly, each die cavity comprises 6 sub-die cavitys 8 and a cast chamber 7, 6 sub-die cavitys 8 distribute around cast chamber 7 in hexagon, each submodule chamber 8 is all communicated with cast chamber 7, cast chamber 7 has sprue gate, backing plate 6 to be positioned at below lower bolster 3 and to have near lower bolster 3 one side the groove holding arm-tie 5, arm-tie 5 is arranged in above-mentioned groove, core rod is made up of multiple submodule core 4 corresponding to submodule chamber 8, core rod and die cavity form dust cover forming cavity, submodule core 4 has push rod, above-mentioned push rod one end is resisted against on arm-tie 5, the other end is against cope match-plate pattern 1 and run through lower bolster 3.
In the present embodiment, sizing material is poured into cast chamber 7 by sprue gate, because submodule chamber 8 is connected with cast chamber 7, thus can realize being poured into by sizing material in multiple submodule chamber 8, production efficiency is high; When after rubber vulcanization, in the process that product is taken out, because core rod is made up of the submodule core 4 corresponding to submodule chamber 8, submodule core 4 can carry out the motion of vertical direction independently of one another, simultaneously, submodule core 4 has push rod, pull-out arm-tie 5, thus submodule core 4 can be ejected, now only middle template 2 need be made to decline, just can easily be taken out by product, depanning efficiency is high.
The above; be only the present invention's preferably detailed description of the invention; but protection scope of the present invention is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to according to technical scheme of the present invention and inventive concept thereof and replace or change, all should be encompassed within protection scope of the present invention.
