Abstract

The utility model discloses an insert-type tilting pin withdrawing structure, which is used for molding a product with barbs or ribs. The ribs are positioned in the withdrawing directions of the barbs; the withdrawing structure is arranged on a mold; the mold is provided with a male mold core; the withdrawing structure comprises an insert and an inclined pin, wherein the insert is fixedly arranged in the male mold core; a rib molding part for molding the ribs is arranged at one end of the insert; a stroke groove is formed in the other end of the insert; the inclined pin is provided with a movable end part; the movable end part is movably arranged in the stroke groove; one side of the movable end part extends and is provided with a barb molding part; the barb molding part is arranged outside the stroke groove. When the mold is opened, the movable end part of the inclined pin moves in the stroke groove of the insert; the barb forming part of the inclined pin is withdrawn out of the barbs gradually; meanwhile, the top of the barb molding part of the inclined pin pushes the product until the ribs are completely separated from the rib molding part, so that the barbs and the ribs can be withdrawn to take out the product.

Description

Insert type finger cam withdrawing structure

[technical field]

The utility model relates to a kind of exit structure, particularly relates to a kind of insert type finger cam withdrawing structure.

[background technology]

On many plastic cement products, all can there is barb, in using mould to carry out moulding, just need to design corresponding structure it is exited.Conventionally can use for example have an inclined pin structure.

Refer to Fig. 1, Fig. 1 illustrates the structural representation into a kind of product.As shown in the figure, described product 10 has barb 11 and rib 12.

Please, again in conjunction with consulting Fig. 2, Fig. 2 illustrates the sectional structure schematic diagram into another visual angle of Fig. 1 product.If use taper pin to exit barb 11 for this product 10, the direction exiting at taper pin can have rib 12, and it cannot be exited.

In view of this, be necessary to develop a kind of insert type finger cam withdrawing structure in fact, to address the above problem.

[summary of the invention]

Therefore, the purpose of this utility model is to provide a kind of insert type finger cam withdrawing structure, solves the product with barb and rib, and described rib is positioned on barb exit axis, the problem that adopts traditional inclined pin structure to exit.

In order to achieve the above object, the insert type finger cam withdrawing structure that the utility model provides, moulding has the product of barb and rib, described rib is positioned on barb exit axis, described exit structure is located in mould, and described mould has male die core, and this exit structure comprises:

Mold insert, is fixed in described male die core, and one end of described mold insert has rib forming part, the other end of rib described in moulding and has stroke groove;

Taper pin, has movable end, and described movable end is movable to be located in described stroke groove, and described movable end one side extension is provided with barb forming part, and described barb forming part is located at outside described stroke groove.

Optionally, described insert type finger cam withdrawing structure is four groups, respectively barb and the rib of shaped article surrounding.

Optionally, the height of described stroke groove be more than or equal to the height of described rib and the first safe clearance and.

Optionally, described the first safe clearance is 2 millimeters.

Optionally, in the time of matched moulds, the beeline between described barb forming part and described rib be more than or equal to described barb protrusion height and the second safe clearance and.

Optionally, described the second safe clearance is 2 millimeters.

Compared to prior art, utilize insert type finger cam withdrawing structure of the present utility model, in the time of die sinking, the movable end of described taper pin moves in the described stroke groove of described mold insert, and the described barb forming part of described taper pin exits described barb gradually; Meanwhile, the top of the described barb forming part of described taper pin promotes described product, until described rib departs from described rib forming part completely; And then can reach exiting of described barb and rib, take out described product.

[specific embodiment]

Incorporated by reference to consulting Fig. 1-Fig. 6, Fig. 3 illustrates as structural representation, Fig. 4 of insert type finger cam withdrawing structure one preferred embodiment of the present utility model illustrate as combination schematic diagram, Fig. 5 of mold insert in Fig. 3 and taper pin illustrate and illustrates the matched moulds state sectional structure schematic diagram into insert type finger cam withdrawing structure one preferred embodiment of the present utility model for decomposition texture schematic diagram, Fig. 6 of Fig. 4.

In order to achieve the above object, the insert type finger cam withdrawing structure that the utility model provides, moulding has the product 10 of barb 11 and rib 12, described rib 12 is positioned on barb 11 exit axis, described exit structure is located in mould, and described mould has male die core 20, and this exit structure comprises:

Mold insert 30, is fixed in described male die core 20, and one end of described mold insert 30 has rib forming part 31, the other end of rib 12 described in moulding and has stroke groove 32;

Taper pin 40, has movable end 41, and described movable end 41 is movable to be located in described stroke groove 32, and described movable end 41 1 sides extensions are provided with barb forming part 42, and described barb forming part 42 is located at outside described stroke groove 32.

Wherein, described product 10 can have barb 11 and rib 12 for surrounding, and described insert type finger cam withdrawing structure should be four groups mutually, respectively barb 11 and the rib 12 of shaped article 10 surroundings.

Wherein, the height (described rib 12 is highly for example 20 millimeters) that the height of described stroke groove 32 is more than or equal to described rib 12 and the first safe clearance (described the first safe clearance is for example 2 millimeters) and.

Wherein, in the time of matched moulds, the beeline between described barb forming part 42 and described rib 12 be more than or equal to described barb 11 protrusion heights and the second safe clearance (described the second safe clearance is for example 2 millimeters) and.

Please, again in conjunction with consulting Fig. 7, Fig. 7 illustrates the die opening state sectional structure schematic diagram into insert type finger cam withdrawing structure one preferred embodiment of the present utility model.

Utilize insert type finger cam withdrawing structure of the present utility model, in the time of die sinking, the movable end 41 of described taper pin 40 is in the interior motion of described stroke groove 32 of described mold insert 30, and the described barb forming part 42 of described taper pin 40 exits described barb 11 gradually; Meanwhile, the top of the described barb forming part 42 of described taper pin 40 promotes described product 10, until described rib 12 departs from described rib forming part 31 completely; And then can reach exiting of described barb 11 and rib 12, take out described product 10.Visible, this structure can be reached rib 12 described in the product 10(with barb 11 and rib 12 and be positioned on barb 11 exit axis) the problem that exits.
