Abstract

The utility model provides an angle pin withdrawing mechanism mounted in a die core of a die. The die core comprises a female die core and a male die core, wherein, a slide block insert is arranged in the male die core; a slide block guiding block inclining at a certain angle from top to bottom in a direction far away from the male die core is arranged on a female die plate. The angle pin withdrawing mechanism comprises a slide block, a guide pin, an angle pin seat and an angle pin, wherein, one end of the slide block is movably connected with the slide block guiding block; the guide pin is mounted in the female die core through an elastic piece; a through hole is formed on the angle pin seat; one end of the angle pin seat is mounted at the other end of the slide block in a manner that the guide pin passes through the through hole, and the other end of the angle pin seat is connected with the slide block insert through the elastic piece; and one end of the angle pin is connected to the angle pin seat. After the adoption of the angle pin withdrawing mechanism, the problem that barbed products cannot be produced because the stroke in the angle pin withdrawing direction is not enough is solved.

Description

A kind of taper pin drawing-out mechanism

Technical field

The utility model relates to the processing fixture, specifically a kind of taper pin drawing-out mechanism of processing overhead kick type product.

Background technology

At present, the slide block of mould is mainly used in the subsidiary products moulding, and overhead kick is arranged on product, and overhead kick wherein partly needs taper pin to withdraw from, if the exit axis stroke is not enough, withdraws from this taper pin formula structure, can bump against other shapes on the product; Therefore, can require to change the shape of product usually.

The utility model content

Because above-mentioned problem, the purpose of this utility model is to overcome the deficiencies in the prior art and defective, provides a kind of and can not produce interference with overhead structure and other shape and structures product

The utility model discloses a kind of taper pin drawing-out mechanism, it is installed in the die of mould, this die comprises mother module core and male model benevolence, wherein, be provided with slide block in the male model benevolence and go into son, be provided with from top to bottom to the SLIDE GUIDE that tilts to have certain angle away from described male model benevolence direction, wherein in described caster, this taper pin drawing-out mechanism comprises: slide block, and an end links to each other in movable ground mode with described SLIDE GUIDE; Guide finger is installed in the described mother module core by elastic component; Offer the taper pin seat of through hole, the mode that the one end passes guide finger with through hole is installed on the other end of slide block, and the other end is gone into son by elastic component and described slide block and linked to each other; Taper pin, an end are connected on the described taper pin seat.

More excellent, this taper pin drawing-out mechanism also comprises: block, be fixed on the described male model benevolence in the mode of the other end that is placed on described SLIDE GUIDE.

More excellent, described elastic component is a spring.

Compared with prior art, the utility model has solved the problem that can't process overhead kick type product inadequately because of taper pin exit axis stroke.

The specific embodiment

For describing technology contents of the present utility model, structural feature in detail, illustrated in detail below in conjunction with embodiment and conjunction with figs..

See also Fig. 1 and Fig. 2, the structural representation during for the utility model matched moulds.A kind of taper pin drawing-out mechanism, it is installed in the die of mould, this die comprises mother module core 1 and male model benevolence (figure does not show), wherein, be provided with slide block in the male model benevolence and go into son 21, be provided with from top to bottom to the SLIDE GUIDE 11 that tilts to have certain angle away from described male model benevolence direction, wherein in described mother module core 1, this taper pin drawing-out mechanism comprises: slide block 22, one ends link to each other in movable ground mode with described SLIDE GUIDE 11; Guide finger 23 is installed in the described mother module core 1 by spring 3; Offer the taper pin seat 24 of through hole 241, the mode that the one end passes guide finger 23 with through hole 241 is installed on the other end of slide block 22, and the other end is gone into son 21 by spring 3 and described slide block and linked to each other; Taper pin 25, one ends are connected on the described taper pin seat 24; Block 26 is fixed on the described male model benevolence in the mode of the other end that is placed on described SLIDE GUIDE 11.

See also Fig. 3 and Fig. 4, be the utility model die opening state structural representation for the moment.When plastic cement products 4 behind in-mold molding, during die sinking, described slide block 22 is done the below motion left away from described mother module core 1 under the pulling of described SLIDE GUIDE 11, withdraw from thereby drive in the overhead kick structure of described taper pin 25 by described product 4.

See also Fig. 5, the cross-sectional view during for the complete die opening state of the utility model.At this moment, described slide block 22 can stop motion under the effect of described block 26.Finally, make described product 4 by breaking away from fully in the mould.

The above is preferred embodiment of the present utility model only, is not to be used for limiting practical range of the present utility model; Every equivalence of doing according to the utility model changes and revises, and is all covered by claim of the present utility model.
