Specific embodiment

It is described further referring to embodiment of the Fig. 3 to Fig. 6 to the utility model product periphery full chamfering mold.

A kind of full chamfering mold in product periphery, including upper mold 1 and lower die 2, the lower die 2 include lower die chamfering workpiece 21 With 22 are taken off in lower die, 22 are taken off in lower die and is located in lower die chamfering workpiece 21 and is slidably connected, the upper mold 1 includes upper mold chamfering work 12 are taken off in part 11 and upper mold, are taken off 12 in upper mold and are located in upper mold chamfering workpiece 11 and are slidably connected, the upper mold chamfering workpiece 11 Demoulding cylinder 6 is connected separately with lower die chamfering workpiece 21, and 21 periphery of lower die chamfering workpiece is provided with and several horizontal can move Dynamic limited block 8, the limited block 8 is connected with positioning cylinder 7, is taken off on 22 in the lower die and offer several suction holes, described Air intake duct 23 is equipped in suction hole.

As shown in Figure 3 and Figure 4, wherein upper mold chamfering workpiece 11 and the one side close to each other of lower die chamfering workpiece 21 have it is default Chamfering 5 further includes cover half 9 and dynamic model 10, and the lower die chamfering workpiece 21 is fixed on cover half 9, the upper mold chamfering workpiece 11 It is fixed on dynamic model 10,12 is taken off in upper mold and is contradicted on dynamic model 10,22 are taken off in lower die and is contradicted on cover half 9, wherein in lower die The demoulding cylinder 6 of de- 22 connection is arranged on cover half 9, is arranged on dynamic model 10 with the demoulding cylinder 6 that 12 connect is taken off in upper mold.

As shown in Figures 3 and 4,12 are taken off before 4 chamfering of product, in upper mold to contradict on dynamic model 10, and 12 are taken off in upper mold and is made The default chamfering 5 of mould chamfering workpiece 11 is exposed, and the demoulding cylinder 6 that 22 connections are taken off in lower die will take off 22 and jack up upwards in lower die, makes De- 22 upper surface is not less than the top surface of lower die chamfering workpiece 21 in lower die, as shown in Figure 4；Product 4, which is placed in lower die, takes off 22 On, start positioning cylinder 7, positioning cylinder 7 makes limited block 8 push product 4 to designated position, then passes through air intake duct 23 for product 4 are firmly adsorbed in lower die de- 22 surfaces (air intake duct 23 connects exhaust fan or other negative pressure generation mechanisms), at this time under dynamic model 10 It moves, upper mold 1 comes into contact with product 4 and squeezes, while will contracting under the action of extruding with the 22 demoulding cylinders 6 connecting are taken off in lower die It returning, limited block 8 at 21 edge of lower die chamfering workpiece is separate during this, and 11 folding processes of workpiece of upper mold chamfering are without hindrance, and The edge of upper mold chamfering workpiece 11 can be thickened to enhance its intensity, avoid causing to step down because of the obstruction of limited block 8, such as be schemed 22 are taken off shown in 5 and Fig. 6, in lower die to move down until to cover half 9 is contradicted, final upper mold chamfering workpiece 11 connects with lower die chamfering workpiece 21 The full chamfer process of upper and lower surface is completed at touching, 4 edge of product under punching press due to presetting the effect of chamfering 5；Dynamic model 10 leaves fixed Mould 9 will take off 22 by demoulding cylinder 6 and jack up with product 4, directly takes out product 4 in lower die.

Vacuum chamber 93 is provided with below the cover half 9, the air intake duct 23 is connected in vacuum chamber 93, and on vacuum chamber 93 Offer suction mouth.

22 are taken off in lower die during move up and down, air intake duct 23 is able to carry out telescopic moving, not will cause obstruction, together When can prevent gas leakage.

The above is only the preferred embodiment of the utility model, and the protection scope of the utility model is not limited merely to Above-described embodiment, technical solution belonging to the idea of the present invention belong to the protection scope of the utility model.It should refer to Out, for those skilled in the art, it is without departing from the principle of the utility model it is several improvement and Retouching, these improvements and modifications also should be regarded as the protection scope of the utility model.
