Description

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

End pole is one of critical piece of battery, and end pole is that the cone being provided with otic placode by one end is formed, and casts form by alloy lead.Existing one end polar pole die, the technical scheme of this end polar pole die is: include the fixing die body being provided with boss and the mobile die body be sleeved on the described boss of described fixing die body, described fixing die body is provided with a die cavity, the running channel that described mobile die body is provided with a die cavity and 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 communicated with described die cavity; Locating fork and the locating piece of moving-limiting motif position is provided with in described mobile die body side.This end polar pole die in use has following deficiency: 1, demoulding difficulty, because the cavity portion of end pole otic placode is located on fixing die body, first casting plate to be removed during the demoulding, more mobile die body is taken out, the end pole cast could be taken out, labour intensity is large; 2, limit 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 fixing die body place, therefore, in mobile die body, be provided with the running channel be communicated with sprue gate, during cast, add the consumption of raw alloy lead, improve the production cost of battery.

Summary of the invention

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

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

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

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

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

1. stripping operation is simple and convenient, because fixing die body, fixing backform, mobile die body and casting plate are hinged by jointed shaft, the cam handle on casting plate is pulled during the demoulding, driven casting plate to move to the outside of mobile die body by the rotation of cam, cut off cast gate below, then pull the handle of mobile die body, mobile die body is moved laterally, just can open die cavity, take out the end pole cast.

2. a mould can cast out multiple end pole at every turn, and production efficiency is high.

3. die cavity is located at fixing backform and mobile die body place, and sprue gate is directly communicated with die cavity, eliminates running channel, decreases the consumption of raw alloy lead, reduces the production cost of battery.

Detailed description of the invention

Below in conjunction with accompanying drawing embodiment, the invention will be further described:

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 fixing die body 4, mobile die body 5 and casting plate 2, is all connected with flap in one end of fixing die body 4, mobile die body 5 and casting plate 2; Mobile die body 5 is positioned at the side of fixing die body 4, and the flap of mobile die body 5 is inserted in the flap of fixing die body 4; Above fixing die body 4, be placed with the fixing backform 3 that one end is connected with flap, casting plate 2 is placed on the top of fixing backform 3 and mobile die body 5; Casting plate 2, fixing backform 3, fixing die body 4 and mobile die body 5 are undertaken hinged by jointed shaft 1.The die cavity that the fixing die body 4 of the present embodiment all has 6 both sides corresponding with mobile die body 5, casting plate 2 has 6 sprue gates, and fixing backform 3 is communicated with the sprue gate of casting plate 2 at the die cavity of matched moulds state with fixing die body 4 and mobile die body 5.Fixing backform 3, fixing die body 4 are all connected with handle with mobile die body 5 at the other end relative with jointed shaft 1.By hinge, the cam 6 with cam handle 7 controlling mobile die body 5 anglec of rotation is housed in mobile die body 5 side in the bottom of casting plate 2.Because fixing die body, fixing backform, mobile die body and casting plate are hinged by jointed shaft, the cam handle on casting plate is pulled during the demoulding, driven casting plate to move to the outside of mobile die body by the rotation of cam, cut off cast gate below, pull the handle of mobile die body again, mobile die body is moved laterally, just can open die cavity, take out the end pole cast.The die cavity of end pole otic placode is located at fixing backform and mobile die body place, and sprue gate is directly communicated with die cavity, eliminates running channel, decreases the consumption of raw alloy lead, reduces the production cost of battery.A mould can cast out 6 end poles at every turn, and production efficiency is high.

During work, first the handle on mobile die body is pulled, die body, fixing backform and mobile die body matched moulds will be fixed, pull the cam handle be connected with casting plate to make cam forward arc surface to be close to position outside mobile die body, to make the die cavity central alignment after the sprue gate on casting plate and corresponding fixing die body, fixing backform and mobile die body matched moulds.Then the sprue gate of plumbous liquid on casting plate is poured into die cavity, after cooling, pull cam handle, driven by the rotation of cam the outside of casting plate along horizontal direction to mobile die body to move, cut off cast gate below.Pull the handle on mobile die body, open die cavity, take out the end pole cast.
