Battery case mould also comprises that mold insert 8 and purt chew 9; The upper end of mold insert 8 is successively through the first die cavity 41, the second die cavity 31 and the 3rd die cavity 22, chews 9 lower end in contact with purt, and the lower end of mold insert 8 is fixed on base plate 5.
Battery case mould also comprises guide pillar 10, and one end of guide pillar 10 is fixed on base plate 5, and the other end of guide pillar 10 is successively through the corresponding guide pillar perforation arranging on push pedal 3, A plate 2 and panel 1.
Battery case mould also comprises push pedal limited block 11, and push pedal limited block 11 is provided with accommodating position 111, and accommodating position 111 can be concave groove, can be also cavity.One end of push pedal limited block 11 is screwed on fixed head 4, is called stiff end.One end of push pedal 3 is provided with boss 33, and boss 33 can be free to slide in accommodating position 111, in the time of the upper end in contact of boss 33 and push pedal limited block 11, and the distance that restriction push pedal 3 and fixed head 4 are opened.
Battery case mould also comprises A plate limited block (not occurring in figure), the distance that A plate limited block is opened for limiting A plate 2 and push pedal 3.
Battery case mould is in the time of matched moulds state, and panel 1, A plate 2, push pedal 3, fixed head 4 and base plate 5 stack gradually, and the first drag hook 71 links closely mutually with the second drag hook 72.
The battery case mould of describing based on the present embodiment, the die sinking mode of the battery case mould of specific descriptions the present embodiment.
1. die sinking for the first time (the auxiliary front mould bullet piece of drag hook and spring ejects)
As shown in Figure 6, when mould is opened, front mould bullet piece 6 part under the active force of front mould bullet piece spring 61 and the first drag hook 71 and the second drag hook 72 skids off A plate 2, and then drives product section to skid off A plate 2.
Front mould bullet piece 6 easily causes the product cannot the demoulding while inefficacy, the present embodiment adopt the first drag hook 71, the second drag hook 72 and front mould bullet piece spring 61 together auxiliary front mould bullet piece 6 skid off A plate 2.When mould is opened, because the first drag hook 71 and the second drag hook 72 are in the state of linking closely, the active force of the second drag hook 72 to the first drag hook 71 and the active force of front mould bullet piece spring 61, front mould bullet piece 6 is to the direction motion of push pedal 3, because front mould bullet piece 6 moves along the bevel direction of groove 21, the first drag hook 71 is also along with front mould bullet piece 6 is to diagonal crossing, and the second drag hook 72 is vertical direction motion always, when the first drag hook 71 moves to certain distance, in the groove 7211 that boss 711 arranges from the second drag hook plate 721, deviate from, realize the first drag hook 71 and the second drag hook 72 departs from.When front mould bullet piece 6 is spacing by front mould bullet piece limited block 63, the first drag hook 71 and the second drag hook 72 depart from completely.
2. die sinking for the second time
In the time of die sinking for the first time, front mould bullet piece 6 is by front mould bullet piece spring 61, the first drag hook 71 and the auxiliary A plate 2 that ejects of the second drag hook 72, in the time that front mould bullet piece 6 is spacing by front mould bullet piece limited block 63, the first drag hook 71 and the second drag hook 72 depart from completely, now, push pedal 3, fixed head 4, base plate 5, the second drag hook 72 continue to move downward together with mold insert 8 and product, until spacing out between A plate 2 and push pedal 3 equals setpoint distance, wherein, setpoint distance refers to the distance that the A plate limited block (not shown) between A plate 2 and push pedal 3 limits, as shown in Figure 7.
3. die sinking for the third time (product taking-up)
After die sinking for the second time, base plate 5, fixed head 4, the second drag hook 72 continues to move downward together with mold insert 8, the drag hook perforation 32 that the upper end of the second drag hook 72 arranges from push pedal 3, deviate from, simultaneously, because the upper port of mold insert 8 is less than the lower port of product, when die sinking for the third time, product is stayed above push pedal 3, mold insert 8 is deviate from and is rested in the second die cavity 31 that push pedal 3 arranges from product, in the time of push pedal 3 boss 33 of one end setting and the upper end in contact of push pedal limited block 11, illustrate that the distance that push pedal 3 and fixed head 4 pull open equals the distance that push pedal limited block 11 limits, product and mold insert 8 depart from completely, as shown in Figure 8.
The battery case mould of describing based on the present embodiment, the clamping system of the battery case mould of specific descriptions the present embodiment.
1. matched moulds (A plate and push pedal are affixed) for the first time
When matched moulds, panel 1 moves downward together with A plate 2 for the first time, until front mould bullet piece 6 is attached in push pedal 3, front mould bullet piece 6 resets, as shown in Figure 9.
2. matched moulds for the second time
Continue matched moulds, the perforation 33 that the upper end of the second drag hook 72 arranges through push pedal 3, arrives the accommodating position 64 of drag hook that front mould bullet piece 6 arranges, the first drag hook 71 and the second drag hook 72 are collided, under the effect of clamp force, impel the second drag hook 72 to slide to mold center, as shown in figure 10.
3. matched moulds (push pedal and fixed head are affixed) for the second time
Continue matched moulds, the second drag hook 72 is got back to original position under the active force of the second drag hook spring 723, and the first drag hook 71 and the second drag hook 72 link closely, and matched moulds completes, as shown in figure 11.
Above content is in conjunction with concrete embodiment further description made for the present invention, can not assert that specific embodiment of the invention is confined to these explanations.For general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace.
