Description

Technical Field

[0001] The utility model relates to the technical field of battery production and processing, in particular to a battery lead block forging die. Background Art

[0002] A battery is a device that can convert chemical energy into electrical energy, also known as a secondary battery or lead-acid battery. After discharge, the battery can be recharged to regenerate the internal active materials, store electrical energy as chemical energy, and convert chemical energy into electrical energy again when needed. Battery lead blocks are an important component of batteries and are the electrode material of lead-acid batteries. Their main function is to convert chemical energy into electrical energy and provide a steady current to the device when needed. In the process of manufacturing battery lead blocks, the lead block material is placed in a mold and forged by pressurization and heating to form the desired shape and size.

[0003] Common battery lead block forging dies are usually composed of upper dies, lower dies, cavities, gates, mold frames, and heating and cooling systems. First, lead liquid is poured into the cavity through the gate, and the mold frame fixes the upper and lower dies, and the heating and cooling system controls the temperature of the mold to ensure that the lead block can be evenly treated during the heating and cooling process. This is the common battery lead block forging die structure and usage. Traditional battery lead block forging dies cool the mold in air and use the natural convection of air to take away the heat. This method is simple and easy, but the cooling speed is slow. Some battery lead block forging dies spray liquid or air on the mold surface by adding nozzles or fans around the mold to speed up the cooling of the mold. However, in this way, since the heat emitted by the lead liquid is in the mold cavity and radiates from the inside to the outside, the effect of cooling the mold only by cooling the mold externally is low, and the cooling of the mold cannot be further accelerated. For this reason, a battery lead block forging die is proposed. Utility Model Content

[0004] 1. Technical issues to be solved

[0005] In view of the deficiencies in the prior art, the utility model provides a battery lead block forging die to solve the above-mentioned technical problem that the cooling of the die cannot be further accelerated.

[0006] (II) Technical solution

[0007] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a battery lead block forging die, comprising:

[0008] A mold body, and an upper mold base and a lower mold base constituting the mold body, and blocking plates are added at corresponding positions of the front of the upper mold base and the lower mold base;

[0009] The positive guide groove is arranged at the upper part of the inner cavity of the upper die seat and the lower part of the inner cavity of the lower die seat, and the positive guide groove is designed as an S shape. The liquid outlet ends of the positive guide groove extend outward through the inner walls of the upper die seat and the lower die seat and are connected to the corresponding blocking plate.

[0010] The side guide grooves are arranged on both sides of the inner cavity of the upper die seat and the lower die seat, and the side guide grooves are all designed in an S shape as a whole, and are connected with the corresponding positive guide grooves. The liquid inlet ends of the side guide grooves extend outward through the inner walls of the upper die seat and the lower die seat, and are connected with the corresponding blocking plates. The heat absorbing medium is injected into the side guide grooves through the liquid inlet ends, and flows into the connected positive guide grooves, and then the heat absorbing medium that absorbs heat is discharged from the liquid outlet end through the positive guide grooves, and cooperates with the nozzles set outside, so that the mold body can be cooled synchronously inside and outside, further accelerating the cooling speed of the mold.

[0011] Preferably, positioning plates are longitudinally installed around the outer sides of the bottom of the upper die seat, and positioning grooves are longitudinally opened around the outer sides of the top of the lower die seat, and the positioning plates correspond to the positioning grooves. The positioning plates of the upper die seat are inserted into the positioning grooves of the lower die seat, which, on the one hand, ensures that the lead liquid will not leak; on the other hand, avoids misalignment when the upper die seat and the lower die seat are connected.

[0012] Preferably, an inner connecting seat is added at the center of the inner cavity of the upper mold base and the lower mold base, and the outer sides of the inner connecting seat are tightly fitted with the inner walls of the upper mold base and the lower mold base, and the corresponding parts of the inner connecting seat are longitudinally opened with a molding cavity. The inner connecting seat can be connected to the inner cavity of the corresponding upper mold base and the lower mold base, and the lead liquid is cooled and formed through the molding cavity. After long-term use or when molding lead blocks of different shapes, the inner connecting seat can be replaced. On the one hand, lead blocks of different shapes can be molded in the same mold body, which is convenient for operation and use; on the other hand, when it is damaged after long-term use, only the inner connecting seat can be replaced, which greatly reduces the cost of use.

[0013] Preferably, the upper die seat, the lower die seat and the inner connecting seat are all provided with limiting grooves at the center of the front and back surfaces, and the inner cavities of the limiting grooves are vertically inserted with limiting columns. The limiting columns fix the inner connecting seat inside the upper die seat and the lower die seat through the limiting grooves to connect them.

[0014] Preferably, connecting columns are laterally added at the upper and lower parts of the front center of the upper die seat and the lower die seat, and the surface center positions of the connecting columns are connected to the front faces of the corresponding limiting columns. The connecting columns drive the limiting columns to translate on the upper die seat and the lower die seat.

[0015] Preferably, bidirectional screws are vertically added to both sides of the upper die seat and the lower die seat, and sliding blocks are sleeved on the front and rear ends of the surface center of the bidirectional screws and connected to the connecting columns. The rear ends of the bidirectional screws are coaxially connected to rotating wheels, and fixing holes are evenly opened on the front of the rotating wheels, and fixing rods are inserted into the corresponding fixing holes. The rotating wheel drives the bidirectional screws to rotate, and the sliding blocks drive the corresponding connecting columns and limiting columns to move toward each other. After the rotation is completed, the fixing rods are inserted into the corresponding fixing holes of the rotating wheels and connected to the corresponding structures. On the one hand, the rotating wheel can be prevented from driving the bidirectional screws to rotate; on the other hand, it is convenient to drive the connecting columns and limiting columns and the upper die seat and the lower die seat to separate, and the inner connecting seat can be taken out and placed.
