Abstract
The present invention discloses a kind of anti-drawing-die of mould and enters minor structure, which has the male die core and mother module core of shaped article, and the product side has hole post, it is characterised in that the anti-drawing-die, which enters minor structure, to be included：Enter pilot trench, in the male die core, it is described enter pilot trench side there is hanging platform groove；Activity enters son, movable to enter described in pilot trench, and the activity enters sub- top and matches somebody with somebody hole post described in synthesis type, and the activity, which enters sub- bottom, has hanging platform, and the height of the hanging platform is less than the height of the hanging platform groove.During die sinking, the product drives the activity to enter son and moves together by sticking to mould power, and since the activity at this time enters son without being separated between product, when ejection is only the mucous membrane power overcome between the product and the male die core, drawing-die will not be caused, thimble will not push up white.Continue to mold, then the activity enters the hanging platform of son and is limited to the hanging platform groove, stop motion, and the product may proceed to eject, and the activity enters sub to be gradually disengaged with the hole post.
Description
【Technical field】
The present invention relates to a kind of anti-drawing-die to enter minor structure, and in particular to a kind of anti-drawing-die of mould enters minor structure.
【Background technology】
Referring to Fig. 1, Fig. 1 is a kind of schematic cross-sectional view of product.Product 100 as shown in the figure, its side have
Hole post 101.Because the hole post 101 can be molded the hole post 101 with being molded its forming surface bonding, being difficult to depart from
Forming surface cannot be arranged on mother module core, and must be arranged in male die core, but use thimble to be easy to cause when ejecting the product 100
Drawing-die, easily top is white for thimble.
Referring again to Fig. 2, Fig. 2 is schematically shown as the molding die schematic cross-sectional view of product shown in Fig. 1.The mould has
The male die core 103 and mother module core 104 of the product 100 are molded, the male die core 103, which also has, is molded 100 hole post of product
101 outer peripheral portions, also have in the male die core into pilot trench 102, it is described enter pilot trench 102 in have into son 105, it is described enter son
105 tops have the bore section for being molded the hole post 101.When ejecting the product 100, due to the hole post of the product 100
101 can also have very big sticking to mould power, therefore meeting drawing-die during ejection, be easy to cause thimble（It is not shown）Top is white.
In view of this, it is really necessary to provide a kind of anti-drawing-die of mould to enter minor structure, to solve the above problems.
【The content of the invention】
It is therefore an object of the present invention to the anti-drawing-die for providing a kind of mould enters minor structure, solve the prior art for
The product of hole post is molded using mould, during die sinking the problem of easy drawing-die.
In order to achieve the above object, the anti-drawing-die of mould of the invention enters minor structure, which has the public affairs of shaped article
Mode and mother module core, which, which enters minor structure, includes：
Enter pilot trench, in the male die core, it is described enter pilot trench side there is hanging platform groove；
Activity enters son, and movable to enter described in pilot trench, the activity, which enters sub- bottom, has hanging platform, the height of the hanging platform
Height of the degree less than the hanging platform groove.
Optionally, the activity enter it is sub with it is described enter pilot trench wall between friction coefficient it is small.
Compared to the prior art, the anti-drawing-die of mould of the invention enters minor structure, and during die sinking, the product relies on sticking to mould power
Drive the activity to enter son to move together, since the activity at this time enters son without separating between product, when ejection is only
Overcome the mucous membrane power between the product and the male die core, drawing-die will not be caused, thimble will not push up white.Continue to mold, then institute
State activity and enter the hanging platform of son and be limited to the hanging platform groove, stop motion, and the product may proceed to eject, and the activity enters
The sub hole post with the product is gradually disengaged.
【Brief description of the drawings】
Fig. 1 is a kind of schematic cross-sectional view of product.
Fig. 2 is schematically shown as the molding die schematic cross-sectional view of product shown in Fig. 1.
The anti-drawing-die that Fig. 3 is schematically shown as the mould of the present invention enters one preferred embodiment of minor structure molding status architecture schematic diagram.
The anti-drawing-die that Fig. 4 is schematically shown as the mould of the present invention enters one preferred embodiment the first die opening state structural representation of minor structure
Figure.
The anti-drawing-die that Fig. 5 is schematically shown as the mould of the present invention enters one preferred embodiment of minor structure the and die opening state structural representation
Figure.
【Embodiment】
Referring to Fig. 3, the anti-drawing-die that Fig. 3 is schematically shown as the mould of the present invention enters one preferred embodiment of minor structure molding state knot
Structure schematic diagram.
In order to achieve the above object, the anti-drawing-die of mould of the invention enters minor structure, which has shaped article 207
Male die core 201 and mother module core 202,207 side of product have hole post 208, which, which enters minor structure, includes：
Enter pilot trench 203, in the male die core 201, it is described enter 203 side of pilot trench there is hanging platform groove 204；
Activity enters son 205, movable to enter described in pilot trench 203, and the activity enters sub 205 tops with described in synthesis type
Hole post 208, the activity, which enters sub 205 bottoms, has hanging platform 206, and the height of the hanging platform 206 is less than the height of the hanging platform groove 204
Degree.
Wherein, the activity enter son 205 and it is described enter pilot trench 203 wall between friction coefficient it is small so that
It is described state activity enter son 205 and it is described enter pilot trench 203 between mutually move smooth, avoid hindering the product 207.
Please in conjunction with refering to Fig. 4, the anti-drawing-die that Fig. 4 is schematically shown as the mould of the present invention enters one preferred embodiment first of minor structure
Die opening state structure diagram.
During die sinking, the product 207 drives the activity to enter son 205 and moves together by sticking to mould power, due to described at this time
Activity enters son 205 without being separated between product 207, when ejection be only overcome the product 207 and the male die core 201 it
Between mucous membrane power, drawing-die, thimble will not be caused（It is not shown）It will not push up white.
Referring to Fig. 5, the anti-drawing-die that Fig. 5 is schematically shown as the mould of the present invention enters one preferred embodiment of minor structure the and molds shape
State structure diagram.
Continuing to mold, then the activity enters the hanging platform 206 of son 205 and is limited to the hanging platform groove 204, stop motion,
And the product 207 may proceed to eject, the activity enters son 205 and the hole post 208 of the product 207 is gradually disengaged.
