Utility model content
The technical problems to be solved in the utility model there is provided a kind of JAV mould improving pump cover molding effect.
The technical solution of the utility model is as follows:
A kind of pump cover JAV mould, comprise moving clamping plate, fixed clamping plate and two leads, described moving clamping plate is above fixed clamping plate, two described leads are arranged at the upper face diagonal angle of fixed clamping plate, the diagonal angle, position of the corresponding lead of the lower face of described moving clamping plate is provided with two fairleads, described lead and fairlead are socketed and are slidably matched, backing plate is installed with at the upper face of described fixed clamping plate, fixed head is installed with at the upper face of described backing plate, groove is provided with at the middle part of described fixed head, die pad is provided with in described groove, the lower end of described die pad is provided with multiple limit spring, the upper end of multiple described limit spring is all connected and fixed with die pad, lower end is all connected and fixed with the bottom land of fixed head central slot, the upper face of this die pad is also provided with four alignment pins, the angle of adjacent two described alignment pins is 90 °, forming punching head is equipped with at the middle part of described die pad, the bottom of described forming punching head is also connected and fixed with the bottom land of fixed head central slot, the upper surface of described forming punching head flushes with the upper surface of die pad, the lower face of described moving clamping plate is provided with profiled sheeting, and described profiled sheeting is provided with the forming cavity suitable with forming punching head, is provided with suitable pilot hole in the position of corresponding four alignment pins of the lower face of described moving clamping plate.
Adopt above structure, arrange limit spring in the lower end of die pad, die pad is flushed with the upper surface of forming punching head, is convenient to blowing smooth, the alignment pin of setting can locate workpiece, can avoid offseting and ensure the consistent of machining deformation in molding process; Limit spring also can effective restrained stretching length, due to the elastic recoil power effect of limit spring itself, to stretch and buckling strength all can be more even, effectively can prevent drawing crack, wrinkling phenomenon, in addition, under the effect of elastic force, the velocity of displacement in mold pressing process also can be more even, during stretching the varied in thickness of material also can evenly, shaping complete after, work piece can eject by die pad under the screen resilience effect of limit spring, and feeding is convenient, improve processing safety
In order to the bending place destressing at the bottom of pump cover lid, prevent drawing crack or wrinkling, as preferably, the outer of described forming punching head upper surface is fillet structure, and arc radius is 10mm.
In order to give the bending place destressing of pump cover cover rim, prevent drawing crack or wrinkling, as preferably, the forming cavity accent in the middle part of described profiled sheeting is fillet structure, and arc radius is 5mm.
In order to make workpiece uniform force and unanimously shaping, as preferably, described moving clamping plate, fixed clamping plate, backing plate, the center of fixed head, die pad, forming punching head and profiled sheeting is on same straight line.
Beneficial effect: the utility model adds limit spring and alignment pin, make the stretching of Product processing evenly, bend effective, effectively can avoid drawing crack, wrinkling or shaping uneven phenomenon, put, feeding is convenient, production efficiency is high, and security is good.

Fig. 3 is the structural representation of alignment pin.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As Fig. 1, shown in Fig. 2 and Fig. 3, the utility model is by moving clamping plate, the compositions such as fixed clamping plate and two leads 1, described moving clamping plate is above fixed clamping plate, two described leads 1 are arranged at the upper face diagonal angle of fixed clamping plate, the diagonal angle, position of the corresponding lead 1 of the lower face of described moving clamping plate is provided with two fairleads 2, described lead 1 is socketed with fairlead 2 and is slidably matched, backing plate 3 is installed with at the upper face of described fixed clamping plate, fixed head 4 is installed with at the upper face of described backing plate 3, groove is provided with at the middle part of described fixed head 4, die pad 5 is provided with in described groove, the lower end of described die pad 5 is provided with multiple limit spring 7, the upper end of multiple described limit spring 7 is all connected and fixed with die pad 5, lower end is all connected and fixed with the bottom land of fixed head 4 central slot, the upper face of this die pad 5 is also provided with four alignment pins 8, the angle of adjacent two described alignment pins 8 is 90 °, forming punching head 6 is equipped with at the middle part of described die pad 5, the outer of described forming punching head 6 upper surface is fillet structure, arc radius is 10mm.The bottom of described forming punching head 6 is also connected and fixed with the bottom land of fixed head 4 central slot, and the upper surface of described forming punching head 6 flushes with the upper surface of die pad 5; The lower face of described moving clamping plate is provided with profiled sheeting 9, described profiled sheeting 9 is provided with the forming cavity suitable with forming punching head 6, forming cavity accent in the middle part of described profiled sheeting 9 is fillet structure, arc radius is 5mm, is provided with suitable pilot hole in the position of corresponding four alignment pins 8 of the lower face of described moving clamping plate.
