Description

Technical Field

[0001] The utility model relates to the technical field of die-cutting molds, in particular to a battery pole piece forming die-cutting mold convenient for replacing templates. Background Art

[0002] A battery pole piece refers to a thin metal plate in a secondary battery and a battery pack, which is used for manufacturing positive and negative electrodes. When producing and processing a battery pole piece, a die-cutting mold is usually used to form the battery pole piece, and the battery pole piece can be subjected to a punching and forming process through the mutual cooperation between a punching cutter and a fixed template.

[0003] During the use of the existing die-cutting mold, the material is usually formed and punched through the shearing force between a fixed die core (forming template) and a punching cutter. After long-term use, the inner edge of the template is usually worn, which affects the quality of the edge of the punched product. When disassembling the template, since the fixed die core is usually an integral structure with the lower template, it is not convenient to replace it, and only the whole can be replaced, which increases the overall production and processing cost. Therefore, we propose a battery pole piece forming die-cutting mold convenient for replacing templates. Summary of the Utility Model

[0004] In view of the above problems, the utility model provides a battery pole piece forming die-cutting mold convenient for replacing templates, which can solve the problems existing in the above background art.

Guide columns are symmetrically arranged on the top of the connecting bottom block. An upper template is sleeved on the top of the guide columns. Positioning columns are symmetrically arranged on the top of the connecting bottom block. A fixed template is sleeved on the outer side of the surface of the positioning columns. One end of the fixed template is fixedly connected with a fixed connecting block. A fixed through hole is formed inside the fixed template.

[0007] In a further technical solution, a positioning jack is formed on the outer side of the lower template. A connecting and positioning mechanism is fixedly connected to the outer side of the bottom end of the fixed connecting block.

[0008] In a further technical solution, a fixed slot is formed on the outer side of the lower template. A connecting plug is arranged inside the fixed connecting block.

[0009] In a further technical solution, the outer side of the surface of the positioning column fits with the inner side of the fixed through hole, and the inner side of the fixed connecting block fits with the outer sides of the lower template and the connecting bottom block.

[0010] In a further technical solution, the cross-sectional shapes of the fixed slot and the connecting plug are T-shaped, and the inner side of the fixed slot is in mutual fit with the outer side of the surface of the connecting plug.

[0011] In a further technical solution, the connection positioning mechanism includes a fixed connecting plate, a connecting sleeve is fixedly connected to the surface of the fixed connecting plate, a movable plug rod is movably connected inside the connecting sleeve, a stress sleeve is fixedly sleeved on the outer side of the surface of the movable plug rod, a stress spring is fixedly connected between one side of the stress sleeve and one end inside the connecting sleeve, and a connecting pull plate is fixedly connected to one end of the movable plug rod.

[0012] In a further technical solution, a pressure-receiving inclined surface is provided at the other end of the movable plug rod, and the outer side of the surface of the other end of the movable plug rod is in mutual fit with the inner side of the positioning jack.

[0013] The beneficial effects of the present utility model are as follows:

[0014] Through the mutual cooperation between the positioning column and the fixed through hole, the fixed template can be used at the top of the connecting bottom block. Moving the fixed connecting block can drive the fixed template to move quickly, so that the fixed template is separated from the outer side of the surface of the positioning column, and thus the fixed template can be disassembled and replaced quickly, with convenient operation.

[0015] Through the mutual cooperation between the positioning jack and the connection positioning mechanism, the stability of the fixed connecting block can be improved, and thus the use stability of the fixed template can be ensured, so that the fixed template can be used stably, and it can be avoided that when extruding materials during use, the viscosity of the materials drives the fixed template to move upward, with convenient operation.

[0024] As Figures 1-5 shown, a battery pole piece forming die cutting die that is convenient for replacing templates includes a lower template 1. A connection bottom block 2 is provided at the top of the lower template 1. Guide posts 4 are symmetrically provided at the top of the connection bottom block 2. An upper template 5 is sleeved on the top of the guide posts 4. Positioning posts 6 are symmetrically provided at the top of the connection bottom block 2. A fixed template 7 is sleeved on the outer side of the surface of the positioning posts 6. One end of the fixed template 7 is fixedly connected with a fixed connection block 8. A fixed through hole 9 is opened inside the fixed template 7.

[0025] The working principle of the above technical solution is as follows:

[0026] During use, when it is necessary to disassemble and replace the fixed template 7, the fixed connection block 8 is moved upward, so that the fixed template 7 is disengaged from the outer side of the surface of the positioning posts 6, so that the fixed template 7 can be quickly disassembled and replaced, with a simple structure and convenient and fast operation.

[0027] In another embodiment, as Figure 3 shown, a positioning jack 10 is opened on the outer side of the lower template 1, and a connection and positioning mechanism 11 is fixedly connected to the outer side of the bottom end of the fixed connection block 8.

[0028] When it is convenient for the positioning jack 10 and the connection and positioning mechanism 11 to cooperate, the fixed connection block 8 can be stably used, and further the fixed template 7 can be stably used, avoiding the fixed template 7 being driven to move upward between the lower template 1 and the upper template 5 when the mold is split under the adhesion of the material.

[0029] In another embodiment, as Figure 3 and Figure 4 shown, a fixed slot 12 is opened on the outer side of the lower template 1, and a connection plug 13 is provided inside the fixed connection block 8.

[0030] When the positioning template 7 and the fixed connection block 8 are installed and used, the connecting plug 13 can be inserted into the inner side of the fixed slot 12, thereby improving the connection stability.

[0031] In another embodiment, as Figure 1 and Figure 3 shown, the outer surface of the positioning post 6 is in mutual fit with the inner side of the fixed through hole 9, and the inner side of the fixed connection block 8 is in mutual fit with the outer sides of the lower template 1 and the connection bottom block 2.

[0032] It is convenient for the positioning template 7 to be stably sleeved on the outer surface of the positioning post 6 under the action of the fixed through hole 9, and at the same time, the inner side of the fixed connection block 8 can be stably located on the outer sides of the lower template 1 and the connection bottom block 2.

[0033] In another embodiment, as Figure 3 and Figure 4 shown, the cross-sectional shapes of the fixed slot 12 and the connecting plug 13 are T-shaped, and the inner side of the fixed slot 12 is in mutual fit with the outer surface of the connecting plug 13.

[0034] It is convenient for the connecting plug 13 to be stably inserted into the inner side of the fixed slot 12 for connection use.

[0035] In another embodiment, as Figure 5 shown, the connection positioning mechanism 11 includes a fixed connection plate 14, a connection sleeve 15 is fixedly connected to the surface of the fixed connection plate 14, a movable insertion rod 16 is movably connected inside the connection sleeve 15, a force-bearing collar 17 is fixedly sleeved on the outer surface of the movable insertion rod 16, a force-bearing spring 18 is fixedly connected between one side of the force-bearing collar 17 and one end inside the connection sleeve 15, and a connection pull plate 19 is fixedly connected to one end of the movable insertion rod 16.

[0036] It is convenient to pull the connection pull plate 19 to drive the movable insertion rod 16 and the force-bearing collar 17 to move. While compressing the force-bearing spring 18, one end of the movable insertion rod 16 can be withdrawn from the inner side of the positioning jack 10, so as to quickly perform the adjustment operation.

[0037] In another embodiment, as Figure 4 shown, a pressure-receiving inclined surface 20 is provided at the other end of the movable insertion rod 16, and the outer surface of the other end of the movable insertion rod 16 is in mutual fit with the inner side of the positioning jack 10.

[0038] When installing the fixed connection block 8, it is convenient to move from top to bottom, so that the pressure-receiving inclined surface 20 can be squeezed between the top edge of the lower template 1, and the movable insertion rod 16 can automatically contract into the connection sleeve 15, so as to automatically perform the adjustment, and the operation is convenient.

[0039] Working principle of the utility model: During use, when it is necessary to disassemble and replace the fixed template 7, pull the connecting pull plate 19, drive the movable insertion rod 16 and the force-bearing collar 17 to move, compress the force-bearing spring 18, and at the same time, one end of the movable insertion rod 16 can be withdrawn from the inside of the positioning jack 10. Then, move the fixed connection block 8 upward, so that the connecting insertion block 13 can be withdrawn from the inside of the fixed slot 12, and at the same time, the fixed template 7 can be separated from the outer surface of the positioning column 6, thus quickly disassembling and replacing the fixed template 7. When installing the fixed template 7, move the fixed template 7 downward, drive the fixed connection block 8 and the connection positioning mechanism 11 to move, so that the fixed template 7 can be sleeved on the outer surface of the positioning column 6, and the connecting insertion block 13 can be inserted into the inside of the fixed slot 12. At the same time, the top edge of the lower template 1 will squeeze the pressure-receiving inclined surface 20, so that the movable insertion rod 16 can automatically contract into the inside of the connecting sleeve 15, drive the force-bearing collar 17 to move. When the connecting insertion block 13 is completely inserted into the inside of the fixed slot 12, the force-bearing collar 17 can drive the movable insertion rod 16 to reset under the action of the force-bearing spring 18, so that the movable insertion rod 16 automatically inserts into the inside of the positioning jack 10, thereby achieving connection and fixation, and the operation is convenient and fast.

[0040] The above embodiments only represent the specific implementation manners of the utility model, and the description is relatively specific and detailed, but it should not be construed as a limitation on the patent scope of the utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the utility model.
