Description

The end polar pole die

Technical field

The present invention relates to battery manufacturing technology field, especially a kind of casting device for battery metal polar plate or analog.

Background technology

The end pole is one of critical piece of battery, and the end pole is to be made of the cone that an end is provided with otic placode, forms with plumbous casting of alloy.Existing a kind of end polar pole die, the technical scheme of this end polar pole die is: include the mobile die body on the fixedly die body that is provided with boss and the described boss that is sleeved on described fixedly die body, described fixedly die body is provided with a die cavity, and described mobile die body is provided with a die cavity and the running channel that is connected with described die cavity; The top of described mobile die body is provided with casting plate, and described casting plate is provided with a sprue gate that communicates with described die cavity; Be provided with locating fork and the locating piece of moving-limiting motif position in described mobile die body one side.This end polar pole die in use has following deficiency: 1, demoulding difficulty, because the die cavity of end pole otic placode partly is located at fixedly on the die body, to first casting plate be removed during the demoulding, again with mobile die body taking-up, could take out by the end pole that casting is good, labour intensity is large; 2, limited production capacity, each mould can only cast out an end pole at every turn, and production efficiency is low; 3, because the die cavity of end pole otic placode is located at fixedly die body place, therefore, be provided with the running channel that is communicated with the sprue gate in the mobile die body, increased the consumption of raw alloy lead during cast, improved the production cost of battery.

Summary of the invention

Technical problem to be solved by this invention provides a kind of end polar pole die, and this end polar pole die can solve demoulding difficulty and the low problem of production efficiency of prior art.

In order to address the above problem, the technical solution used in the present invention is: this end polar pole die includes fixedly die body and mobile die body and casting plate, and described fixedly die body and described mobile die body and described casting plate are equipped with flap; Described mobile die body is positioned at a side of described fixedly die body, and the described flap of described mobile die body is inserted in the described flap of described fixedly die body; The top of described fixedly die body is provided with the fixedly backform with flap, and described casting plate is located at the top of described fixedly backform and described mobile die body; Described casting plate, described fixedly backform, described fixedly die body and described mobile die body are hinged by jointed shaft; Described fixedly die body and described mobile die body are equipped with a plurality of die cavities, and described casting plate is provided with a plurality of sprue gates, and described fixedly backform and described fixedly die body and described mobile die body are communicated with the sprue gate of described casting plate at the described die cavity of matched moulds state.

In the technical scheme of above-mentioned end polar pole die, technical scheme can also be more specifically: the cam with cam handle that is provided with the described mobile die body anglec of rotation of control in the bottom of described casting plate in described mobile die body one side.

Further, described casting plate, described fixedly backform, described fixedly die body and described mobile die body are equipped with handle.

Owing to having adopted technique scheme, the present invention compared with prior art has following beneficial effect:

1. stripping operation is simple and convenient, since fixedly die body, fixedly backform, mobile die body and casting plate are hinged by jointed shaft, pull the cam handle on the casting plate during demoulding, rotation by cam drives casting plate to the outer side shifting of mobile die body, cut off following cast gate, pull again the handle of mobile die body, make mobile die body mobile laterally, just can open die cavity, take out the good end pole of casting.

2. a mould can cast out a plurality of end poles at every turn, and production efficiency is high.

3. die cavity is located at fixedly backform and mobile die body place, and the sprue gate directly is communicated with die cavity, has cancelled running channel, has reduced the consumption of raw alloy lead, has reduced the production cost of battery.

The specific embodiment

The invention will be further described below in conjunction with accompanying drawing embodiment:

Be the end pole of battery as shown in Figure 1 and Figure 2.End polar pole die as shown in Figure 3, Figure 4 includes fixedly die body 4, mobile die body 5 and casting plate 2, all is connected with flap at a fixing end of die body 4, mobile die body 5 and casting plate 2; Mobile die body 5 is positioned at a fixedly side of die body 4, and the flap of mobile die body 5 is inserted in the flap of fixing die body 4; Be placed with the fixedly backform 3 that an end is connected with flap above fixing die body 4, casting plate 2 is placed on the fixedly top of backform 3 and mobile die body 5; Casting plate 2, fixedly backform 3, fixedly die body 4 and mobile die body 5 are undertaken hinged by jointed shaft 1.The fixedly die body 4 of the present embodiment all has 6 die cavities that both sides are corresponding with mobile die body 5, and 6 sprue gates are arranged on the casting plate 2, fixedly backform 3 and fixedly die body 4 and mobile die body 5 are communicated with the sprue gate of casting plate 2 at the die cavity of matched moulds state.Fixedly backform 3, fixedly die body 4 and mobile die body 5 all are connected with handle at the other end relative with jointed shaft 1.The cam 6 with cam handle 7 of mobile die body 5 anglecs of rotation of control is housed by hinge in mobile die body 5 one sides in the bottom of casting plate 2.Since fixedly die body, fixedly backform, mobile die body and casting plate are hinged by jointed shaft, pull the cam handle on the casting plate during demoulding, rotation by cam drives casting plate to the outer side shifting of mobile die body, cast gate below cutting off, pull again the handle of mobile die body, make mobile die body mobile laterally, just can open die cavity, take out the good end pole of casting.The die cavity of end pole otic placode is located at fixedly backform and mobile die body place, and the sprue gate directly is communicated with die cavity, has cancelled running channel, has reduced the consumption of raw alloy lead, has reduced the production cost of battery.A mould can cast out 6 end poles at every turn, and production efficiency is high.

During work, at first pull the handle on the mobile die body, fixedly die body, fixedly backform and mobile die body matched moulds, pull the cam handle that is connected with casting plate and make cam forward the position that arc surface is close to the mobile die body outside to, make sprue gate on the casting plate and corresponding fixedly die body, the fixing die cavity central alignment behind backform and the mobile die body matched moulds.Then the sprue gate of plumbous liquid on casting plate poured into die cavity, after cooling, pull cam handle, the rotation by cam drives the outer side shifting of casting plate along horizontal direction to mobile die body, the cast gate below cutting off.Pull the handle on the mobile die body, open die cavity, take out the good end pole of casting.
