The utility model discloses a can the very fast separation of the merciful and peaceful base of messenger's activity mould just prevent that the two friction is impaired.

Description

A kind of diel

Technical field

The utility model relates to technical field of mold, particularly relates to a kind of diel for punching press auto panel.

Background technology

On automobile stamping production line, fast far away than hydraulic type stamping machine of the drawing velocity of mechanical type stamping machine, this just needs movable mould core can be separated faster with the base of patrix, but quick separating can make mutual friction between the two between existing movable mould core and base, especially the two degree of wear can be made to strengthen when high-speed friction, guide plate by the face that the two contacted respectively being provided with equal number in prior art reduces the two friction, but guide plate can make separating rate slow down contacting with each other in process, is unsuitable for automated production.

Utility model content

In view of this, the purpose of this utility model is to propose a kind of diel, and movable mould core can be made comparatively fast to be separated with base.

For reaching this object, the utility model by the following technical solutions:

A kind of diel, comprise the movable mould core and base that are connected with patrix respectively, the below of described movable mould core and the top of base are installed with wedge slide respectively, and the wedge slide on described movable mould core is relative with the wedge slide on base and establish;

The hypotenuse of described wedge slide and the angle α of horizontal plane are 35 °-50 °, and described movable mould core and base move toward one another are separated after driving the wedge slide on described movable mould core to contact with each other with the hypotenuse of the wedge slide on base.

In the utility model one embodiment, the hypotenuse of described wedge slide and the angle α of horizontal plane are 45 °.

In the utility model one embodiment, described wedge slide and movable mould core are connected by screw.

In the utility model one embodiment, described wedge slide is provided with counter sink.

The utility model beneficial effect:

By arranging wedge slide in the bottom of movable mould core and the top of base in the utility model, movable mould core and the mutual friction of base phase can be prevented and make the two wear and tear, and the angle [alpha] of wedge slide is 35 °-50 °, movable mould core and base can be made to be separated faster or to fold.

Detailed description of the invention

In order to make those skilled in the art understand the technical solution of the utility model better, further illustrate the technical solution of the utility model below in conjunction with accompanying drawing by detailed description of the invention.

Please refer to Fig. 1, Fig. 1 is the structural representation of the diel movable mould core that provides of the utility model and base.

Present embodiments provide for a kind of diel, comprise the movable mould core 1 and base 2 that are connected with patrix respectively, movable mould core 1 can be made to be separated faster with base 2, and the two does not have wearing and tearing, the below of described movable mould core 1 and the top of base 2 are installed with wedge slide 3 respectively, and the wedge slide 3 on described movable mould core 1 is relative with the wedge slide 3 on base 2 and establish;

More specifically, the hypotenuse of described wedge slide 3 and the angle α of horizontal plane are 35 °-50 °, when angle α between the hypotenuse of wedge slide 3 and horizontal plane is within the scope of this, the two separating rate is very fast compared with other angles, described movable mould core 1 and base 2 move toward one another, be separated after driving the wedge slide 3 on described movable mould core 1 to contact with each other with the hypotenuse of the wedge slide 3 on base 2, when movable mould core 1 works with base, movable mould core 1 along with patrix to the below in figure then to the forward in figure, because movable mould core 1 and the wedge slide 3 on base 2 are arranged in opposite directions, and then two the hypotenuse of relative wedge slide 3 can contact with each other, movable mould core 1 can be made to be separated fast with base 2 or to fold.

Please composition graphs 2, Fig. 2 be the structural representation of the wedge slide of the diel that the utility model provides further.

More specifically, in present embodiment, the hypotenuse of described wedge slide 3 and the angle α of horizontal plane are 45 °.Preferably, wedge slide 3 described in present embodiment and movable mould core 1 are connected by screw.And described wedge slide 3 is provided with when counter sink 4 can ensure that wedge slide 3 contacts with each other like this and can not scratches because of the screw spilt and make movable mould core and base be worn.

Note, above display and describe general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not by the restriction of above-mentioned embodiment; what describe in above-mentioned embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications; these changes and improvements all fall within the scope of claimed the utility model, and claimed scope of the present utility model is defined by appending claims and equivalent thereof.
