Abstract

The utility model discloses a mold-drawing-preventing insert core structure of a mold. The mold comprises a male mold core and a female mold core for molding a product, wherein a bore column is arranged on one side of the product. The mold-drawing-preventing insert core structure is characterized by comprising an insert core groove and a movable insert core, wherein the insert core groove is formed in the male mold core; a hanging table groove is formed in one side of the insert core groove; the movable insert core is movably arranged in the insert core groove; the bore column is molded at the top end of the movable insert core cooperatively; a hanging table is arranged at the bottom end of the movable insert core; the height of the hanging table is smaller than that of the hanging table groove. During mold opening, the product drives the movable insert core to move together by virtue of mold sticking force; the movable insert core does not need to be separated from the product, and the mold sticking force between the product and the male mold core is only overcome during ejection, so that mold drawing cannot be caused, and an ejector pin cannot generate an ejector mark. If the mold opening is continued, the hanging table of the movable insert core is limited by the hanging table groove; if the movement is stopped, the product is continued to be ejected, and the movable insert core is gradually separated from the bore column.

Description

The anti-drawing-die of mould enters minor structure

[technical field]

The utility model relates to a kind of anti-drawing-die and enters minor structure, and the anti-drawing-die that is specifically related to a kind of mould enters minor structure.

[background technology]

Refer to Fig. 1, the sectional structure schematic diagram that Fig. 1 is a kind of product.Product 100 as shown in the figure, one side has hole post 101.Because described hole post 101 can be bonding with its forming surface of moulding, be difficult to depart from, so the forming surface of hole post 101 can not be located at mother module core described in moulding, and must be located in male die core, but while adopting thimble to eject described product 100, easily causing drawing-die, thimble easily top is white.

Referring again to Fig. 2, Fig. 2 illustrates the mould sectional structure schematic diagram into product shown in Fig. 1.Described mould has male die core 103 and the mother module core 104 of product 100 described in moulding, described male die core 103 also has product 100 hole post 101 outer peripheral portions described in moulding, in described male die core, also have into pilot trench 102, describedly enter in pilot trench 102 to have into son 105, described in enter the interior bore portion that sub 105 tops have hole post 101 described in moulding.While ejecting described product 100, because the hole post 101 of described product 100 also can have very large sticking to mould power, can drawing-die while therefore ejecting, easily cause thimble (not shown) top white.

In view of this, be necessary to provide a kind of anti-drawing-die of mould to enter minor structure in fact, to address the above problem.

[summary of the invention]

Therefore, the anti-drawing-die that the purpose of this utility model is to provide a kind of mould enters minor structure, solves prior art and adopts mould to carry out moulding, the problem of easy drawing-die during die sinking for the product with Kong Zhu.

In order to achieve the above object, the anti-drawing-die of mould of the present utility model enters minor structure, and this mould has male die core and the mother module core of shaped article, and described product one side has Kong Zhu, and this anti-drawing-die enters minor structure and comprises:

Enter pilot trench, be located in described male die core, described in enter pilot trench one side and there is hanging platform groove;

Activity enters son, enters in pilot trench described in movable being located at, and described activity enters sub-top and coordinates Kong Zhu described in moulding, and described activity enters sub-bottom and has hanging platform, and the height of described hanging platform is less than the height of described hanging platform groove.

Optionally, described activity enter son and described in the coefficient of friction that enters between pilot trench wall little.

Compared to prior art, the anti-drawing-die of mould of the present utility model enters minor structure, during die sinking, described product relies on sticking to mould power to drive described activity to enter son and moves together, due to now described activity enter son without with product between separated, while ejecting, be only the mucous membrane power overcoming between described product and described male die core, can not cause drawing-die, thimble can not push up white.Continue die sinking, the described hanging platform that described activity enters son is limited to described hanging platform groove, stop motion, and described product can continue to eject, it is separated gradually with the described Kong Zhu of described product that described activity enters son.

[accompanying drawing explanation]

Fig. 1 is a kind of sectional structure schematic diagram of product.

Fig. 2 illustrates the mould sectional structure schematic diagram into product shown in Fig. 1.

The anti-drawing-die that Fig. 3 illustrates as mould of the present utility model enters minor structure one preferred embodiment matched moulds status architecture schematic diagram.

The anti-drawing-die that Fig. 4 illustrates as mould of the present utility model enters minor structure one preferred embodiment the first die opening state structural representation.

The anti-drawing-die that Fig. 5 illustrates as mould of the present utility model enters minor structure one preferred embodiment the second die opening state structural representation.

[specific embodiment]

Refer to Fig. 3, the anti-drawing-die that Fig. 3 illustrates as mould of the present utility model enters minor structure one preferred embodiment matched moulds status architecture schematic diagram.

In order to achieve the above object, the anti-drawing-die of mould of the present utility model enters minor structure, and this mould has male die core 201 and the mother module core 202 of shaped article 207, and described product 207 1 sides have hole post 208, and this anti-drawing-die enters minor structure and comprises:

Enter pilot trench 203, be located in described male die core 201, described in enter pilot trench 203 1 sides and there is hanging platform groove 204;

Activity enters son 205, enters in pilot trench 203 described in movable being located at, and described activity enters sub 205 tops and coordinates hole post 208 described in moulding, and described activity enters sub 205 bottoms and has hanging platform 206, and the height of described hanging platform 206 is less than the height of described hanging platform groove 204.

Wherein, described activity enter son 205 with described in the coefficient of friction that enters between the wall of pilot trench 203 little, thereby can so that described in state activity enter son 205 with described in enter that 203 of pilot trench are mutual to move smooth and easyly, avoid hindering described product 207.

Please, again in conjunction with consulting Fig. 4, the anti-drawing-die that Fig. 4 illustrates as mould of the present utility model enters minor structure one preferred embodiment the first die opening state structural representation.

During die sinking, described product 207 relies on sticking to mould power to drive described activity to enter son 205 motion together, due to now described activity enter son 205 without with product 207 between separated, while ejecting, be only the mucous membrane power overcoming between described product 207 and described male die core 201, can not cause drawing-die, thimble (not shown) can not pushed up white.

Refer to Fig. 5, the anti-drawing-die that Fig. 5 illustrates as mould of the present utility model enters minor structure one preferred embodiment the second die opening state structural representation.

Continue die sinking, the described hanging platform 206 that described activity enters son 205 is limited to described hanging platform groove 204, stop motion, and described product 207 can continue to eject, it is separated gradually with the described hole post 208 of described product 207 that described activity enters son 205.
