Abstract
The invention discloses a mold insert-type angle pin release structure. A mold is used for molding a product with a barb and ribs and the barb is located along the barb release direction. The mold insert-type angle pin release structure is arranged in the mold. The mold comprises a main mold core. The mold insert-type angle pin release structure comprises a mold insert which is fixed in the main mold core and has one end with a rib molding part for molding the rib and the other end with a stroke groove, and an angle pin which is provided with a movable end part movably arranged in the stroke groove, wherein one side of the movable end part extends to form a barb molding part arranged outside the stroke groove. In mold opening, the movable end part of the angle pin moves in the stroke groove of the mold insert, the barb molding part of the angle pin gradually releases the barb, the top end of the barb molding part of the angle pin pushes the product until all the ribs are completely separated from the rib molding parts so that barb and rib release is realized and the product can be taken out of the mold.
Description
[technical field]
The present invention relates to a kind of exit structure, particularly relate to a kind of insert type finger cam withdrawing structure.
[background technology]
All can there is barb in many plastic cement products, use mould carry out shaping in just need to design corresponding structure it exited.Usually can use such as have 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 combine again and consult Fig. 2, Fig. 2 illustrates the sectional structure schematic diagram at another visual angle into Fig. 1 product.If use taper pin to exit barb 11 for this product 10, rib 12 can be had in the direction that taper pin exits, it cannot be exited.
In view of this, be necessary to develop a kind of insert type finger cam withdrawing structure, to solve the problem in fact.
[summary of the invention]
Therefore, the object of this invention is to provide a kind of insert type finger cam withdrawing structure, solve the product with barb and rib, described rib is positioned on barb exit axis, adopts the problem that traditional inclined pin structure cannot exit.
In order to achieve the above object, insert type finger cam withdrawing structure provided by the invention, the shaping product with barb and rib, described rib is positioned on barb exit axis, and 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 the rib forming part of shaping described rib, the other end has stroke groove;
Taper pin, has movable end, and described movable end is movable to be located in described stroke groove, and the extension of described movable end side 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, the barb of difference shaped article surrounding and rib.
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 first safe clearance is 2 millimeters.
Optionally, when 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 second safe clearance is 2 millimeters.
Compared to prior art, utilize insert type finger cam withdrawing structure of the present invention, when 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 exiting of described barb and rib can be reached, take out described product.
