Detailed Description

The present invention is described in detail below with reference to the attached drawings:

as shown in fig. 1, 2, 3 and 4, the cast-weld mold for the automatic cast-weld machine comprises a horizontally arranged main mold 1, a first connecting component 2 and a second connecting component 3 which are sequentially extended and connected from the left side and the right side of the main mold 1, so that the shape is similar to a U shape, the main mold 1 is small in immersion volume when immersed in a lead liquid tank of the automatic cast-weld machine, the stirring of the lead liquid is less, and the generation of lead slag is reduced. The main mold 1 includes three cast-on beams 11 extending in the longitudinal direction in the left-right direction and parallel to each other, and main beams 12 provided orthogonal to the ends of the cast-on beams 11 and connecting the cast-on beams 11 to form the main mold 1 of the frame structure. In this embodiment, two paired forming grooves 13 for storage battery cluster cast welding are disposed on the upper surface of each cast-weld beam 11 at left and right intervals, so that the structure in this embodiment can be used to cast-weld 6 batteries (2 × 3 or other rectangular matrix distribution in other preferred embodiments) at one time, and in this embodiment, in order to ensure the strength, a beam body slightly narrower than the main beam 12 is disposed between the two groups of forming grooves 13 on one cast-weld beam 11, and a connecting ridge 14 is disposed between the cast-weld beams 11. The connecting ridges 14 in this embodiment are formed in a fishbone-like distribution extending obliquely outward from the middle of the main mold 1, so that a uniform distribution of structural strength from the center to the outside can be achieved. When cast-weld, the main mold 1 is immersed in lead liquid in advance for preheating, when the batteries run to the upper part (a plurality of batteries can be automatically transported and moved by using a turnover plate with a plurality of containing structures), the main mold 1 is lifted from the lead liquid pool under the action of an external driving device until only the lead liquid is contained in the forming groove 13, and then, the tabs of the batteries are downwards inserted into the forming groove 13 through the driving of an automatic cast-weld machine for cast-weld, so that a batch of high-efficiency automatic cast-weld can be realized. Through setting up the girder at the both ends of cast joint roof beam 11 for when following first coupling assembling 2, second coupling assembling 3 of connection, actions such as reduction welding, spiro union have caused the deformation of cast joint roof beam 11, because be used for the synchronous welding of big battery in batches, structure, spatial position homogeneity between each cast joint roof beam 11 have obtained the assurance through girder 12.

In this embodiment, the main mold 1 includes a first flow channel 15 located in each cast-on beam 11 and penetrating along the length direction thereof, the first flow channel 15 and the lower second flow channel 21 and third flow channel 33 are used for passing a cooling liquid, and after the battery tab is inserted into the forming groove 13 and cast-welded by the molten lead, the cast-on structure is cooled and shaped by injecting the cooling liquid into the flow channels.

In this embodiment, the first connecting assembly 2 is an L-shaped bent pipe extending upward from the left and right sides of the main mold 1, and has three bent pipes corresponding to the left and right sides of the three cast-weld beams 11, a second flow passage 21 is provided in the first connecting assembly 2 along the extending direction thereof, and the end of the second flow passage 21 corresponds to the end of the first flow passage 15 and is connected in a sealing manner by welding or sealing screw threads to prevent leakage.

In this embodiment, the second flow channel 21 is provided with a flared flow guiding portion 22 at the end connected to the first flow channel 15, and the flow guiding portion 22 is located such that the flow cross-sectional area of the first flow channel 15 is larger than that of the second flow channel 21 and has relatively continuous transition, so that the coolant has relatively small and relatively stable flow velocity and flow state at the first flow channel 15, thereby having better cooling effect.

In this embodiment, the second connecting assembly 3 includes the connecting plate 31 of flat structure, the connecting pipe 32, be equipped with the third runner 33 of one end sealing connection second runner 21 in the connecting pipe 32, the outside coolant liquid circulating device (like circulating water pump) is connected to the third runner 33 other end, connecting plate 31 rigid coupling is in the connecting pipe 32 top, the connecting plate 31 is used for connecting outside drive arrangement (like the cylinder), be equipped with the open via hole of symmetry on the connecting plate 31 in this embodiment, can connect the piston rod of cylinder with the elastic mode of slight deformation, thereby realize the removal in the above-mentioned cast joint action under the drive of cylinder.

In this embodiment, the connecting tube 32 is externally provided with a connecting block 34 and connected with the connecting block to form an L-shaped bent structure (refer to fig. 2). The connecting blocks 34 are parts of an integrated structure, and one connecting block 34 is integrally connected with three connecting pipes 32 corresponding to the first connecting assembly 2 through sealing screw threads or welding and is upwards screwed and connected to the connecting plate 31. The hole in the connecting piece 34 in this embodiment and the hole in the connecting tube 32 together constitute a third flow passage. The integrated connecting block 34 structure enables the first connecting assemblies 2 and the connecting pipes 32 of multiple structures to be connected through an integrated structure, so that the limitation of the freedom of movement in the extending direction of the first connecting assemblies and the connecting pipes is better, namely, the mounting structure is more stable, and the problems that the shaking, the deformation and the like affect the production quality are effectively reduced.

In this embodiment, the upper surface of the cast-on beam 11 is a smooth and integral plane convenient for cleaning by scraping lead, and the inner wall of the first flow channel 15 in the cast-on beam 11 has the same thickness from the lower surface of the cast-on beam 11, i.e. the portion below the upper surface has the same wall thickness. Because the die is immersed in the lead liquid pool before cast welding and the lower half part of the die is immersed in the lead liquid pool to keep a certain cast welding temperature during cast welding, the battery pole lug is fully melted to realize high-quality cast welding. Therefore, the heat conducting capacity of the part immersed in the lead liquid pool is basically the same through the structure with the same wall thickness, and under the working condition of synchronous cast welding of a plurality of batteries, the external parameters of cast welding forming of each battery are stable through the basically synchronous heat conducting capacity, the output quality is good, and the stability is high. At the same time, the above-mentioned connecting ridges 14 connected between the respective cast-on beams 11 also provide the function of conducting heat between the cast-on beams 11 to make the temperature uniform between the different cast-on beams 11.

In this embodiment, the cast-on-beam 11 has a reinforcing ridge 16 on its lower surface along its extending direction, thereby reducing the deformation of its thin uniform-thickness structure under the action of high-heat molten lead, and improving structural strength, stability and output quality.

In this embodiment, the positioning holes 17 are formed in the upper surface of the main beam 12 for positioning the turnover plate for installing the battery, and the positioning holes 17 are formed in the main beam 12 so that the positioning holes 17 do not affect the cast-weld beams 11 during processing and positioning.
