Specific embodiment

As described below is only the preferred embodiment of the utility model, is not defined to the scope of the utility model.

Embodiment: as shown in attached drawing 1,2,3 and attached drawing 4, a kind of subregion cooling device of cast-on strap mold, including Liquid feeding mold block 1, is arranged in the liquid feeding mold block 1 and is used to form the molding die block 2 of busbar connector, setting it is described at In type mold block 2 and for synchronizing the first cooling cooling unit 3, and setting to lead liquid in the molding die block 2 It goes up and is used to carry out the second independently cooling cooling unit 4 to the single busbar connector forming process.

In the present embodiment, the cooling tool of the subregion is there are two types of effect, first be in the liquid feeding mold block 1 toward it is described at It in type mold block 2 when injection lead liquid, is separate from due to two kinds, so the liquid feeding mold block 1 and the molding die Between block 2, control can be independently cooled down between the different molding die blocks 2, mutual temperature interference situation is small, reaches It is to have multiple notches for cast-on strap on the single molding die block 2 to the effect of subregion, accurate temperature control, second, Corresponding second cooling unit 4 in multiple positions can carry out the single notch independent cooling, be finally reached temperature symbol The purpose of each different busbar connector requirements is closed, guarantee busbar connector is in cast welding well together with tab welding.

The molding die block 2 includes mold block main body 201, is arranged in the mold block main body 201 and is used for cast welding The front end forming tank 202 of busbar connector plate body is formed, and is connected with the front end forming tank 202 and converges for cast welding molding The rear end forming tank 203 of organ timbering body, first cooling unit 3 setting are described in 202 lower position of front end forming tank Second cooling unit 4 is positioned close at 203 position of rear end forming tank.

In the present embodiment, the lead liquid depth in the rear end forming tank 203 is greater than the front end forming tank 202, and two Requirement of the person for cooling temperature and cooling duration be all it is different, this can pass through corresponding first cooling unit 3 and second cooling unit 4 realize, and different busbar connector forming tank, can the different positive and negative anodes tab of inserting thickness, this When welding institute's calorific requirement it is also different, this just need second cooling unit 4 below the busbar connector forming tank carry out solely Vertical cooling settings, i.e., cast welding temperature requirement is low in the busbar connector forming tank, then intensity of cooling improves, otherwise temperature requirement is high, Intensity of cooling is then reduced, it is final to guarantee that cast welding everywhere is stablized, it will not lead to the problem of that the welding is not firm and tab fusing.

Second cooling unit 4 includes the water cooling tank 401 being arranged on 2 lower surface of molding die block, setting Envelope block 402 on the water cooling tank 401, and the water inlet 403 and water outlet 404 that are arranged on the envelope block 402.

In the present embodiment, second cooling unit 4 is for targetedly cooling down cast welding in the rear end forming tank 203 Temperature when busbar connector cylinder is formed, water is sprayed from the water inlet 403, is beaten on each side in the water cooling tank 401, Water-cooled cooling is formed, to reach the specific required cast welding temperature in the position.

Second cooling unit 4 further includes setting up and being used for from 401 inner top surface of water cooling tank described in cooling The middle part cooling bath 405 of the busbar connector cylinder in rear end forming tank 203.Second cooling unit 4 further includes from described 401 inner top surface of water cooling tank sets up and is used to cool down the side of the busbar connector cylinder in the rear end forming tank 203 Cooling bath 406.Several described side cooling baths 406 are spaced setting on 401 inner top surface of water cooling tank, and the side is cold But the groove depth of slot 406 is greater than the middle part cooling bath 405.The side cooling bath 406 be arranged far from the front end at At 202 1 side position of type groove.

In the present embodiment, the middle part cooling bath 405 is directed at the rear end forming tank 203, and the side cooling bath 406 are located at 203 side of rear end forming tank, deep compared with the former and measure more, the two combination, and to guarantee cooling effect, water is from described Water inlet 403 enters, and can effectively be sprayed on the middle part cooling bath 405 and the side cooling bath 406, reaches basic cold But effect.

The independent connection inlet pipeline of the water inlet 403 of different second cooling units 4.First cooling unit 3 include the water cooling channel 301 being arranged on the molding die block 2, and 301 both ends of water cooling channel are arranged in Pipe connectors 302.The thermometer hole 5 for hygrosensor to be arranged is additionally provided on the molding die block 2.

In the present embodiment, water flowing in the water cooling channel 301, based on synchronous cooling mode, be mainly used for cold The busbar connector block in the front end forming tank 202, and the remittance at 301 water inlet position of water cooling channel Stream row's cast welding slot, water temperature is relatively low at this time, and 3 intensity of cooling of the first cooling unit is larger therefore described at the position Second cooling unit 4 can reduce intensity of cooling, and at 301 water outlet position of the water cooling channel, and water temperature is relatively Height, 203 position of rear end forming tank at this need to improve intensity of cooling, guarantee cooling under the premise of cast welding requires identical The consistency of intensity.

On the other hand, when the positive and negative anodes tab for needing cast welding different on the entire molding die block 2, different intermediate use When bilateral type busbar connector and the single type side busbar connector for being used to form binding post, needed for each busbar cast welding slot With regard to different, this just needs early period and different temperatures has been determined temperature, and is supervised in real time under the measurement of the thermometer hole 5 Control is whole, to guarantee the cooling effect of independent, subregion, so that the cast welding slot that different temperatures requires can stablize cast welding, avoids out The problem of existing cast welding intensity is inadequate or the excessively high tab of temperature melts, this is that whole cooled cast welded mold is not achieved.

The embodiments of the present invention is explained in detail above in conjunction with attached drawing, but the utility model is not limited to State embodiment, within the scope of knowledge possessed by those of ordinary skill in the art, can also do not depart from it is practical Various modifications are made under the premise of novel objective.These are all without creative modification, as long as in the power of the utility model All by the protection of Patent Law in sharp claimed range.
