[0003] Currently, during the stamping process, the insulating sheets at both ends of the battery are prone to adhere to the cutter head. This situation not only affects the continuity of production, but may also cause the insulating sheets to be damaged or deformed due to the demolding operation of the mechanical ejector, thereby affecting the quality of the product and the convenience of subsequent use. Therefore, improvement is needed. Utility Model Content

Although this can demould the insulating sheets, the insulating sheets will be lifted up by the cutter head, making it inconvenient to carry out continuous work.
[0005] In view of this, the utility model provides an automatic demoulding structure for a stamping die for an insulating sheet, comprising a die plate, a plurality of cutter heads being fixedly mounted on the bottom of the die plate, and the die plate being provided with a synchronous demoulding component and an anti-slip component;

Several of the sliding rods are slidably connected at the four corners of the mold plate, the fixed plate is fixedly installed at one end of the top of the sliding rod, the pressure plate is fixedly installed at one end of the bottom of the sliding rod, the synchronous return spring is sleeved on the outside of the sliding rod, several of the cutting edges are opened in the middle of the pressure plate, and one end of several of the ejector rods is fixedly installed at the bottom of the fixed plate.
[0007] Optionally, one end of the synchronous return spring is against the bottom surface of the mold plate, and the other end of the synchronous return spring is against the top surface of the pressure plate.
[0008] Optionally, the diameter of the blade entry is larger than the diameter of the blade head, and the blade entry is sleeved on the outside of the blade head, and the bottom height of the blade entry is 0.3-0.4 cm lower than the bottom height of the blade head.

Specifically, when the die plate drives the cutter head to press down for stamping, the insulating sheet raw material with a self-adhesive layer is punched out to the size of the battery end face. At the same time as the knife is lifted, the pressure plate and the push rod press down the stamped insulating sheet under the action of a synchronous return spring, so that the insulating sheet is separated from the cutter head and remains on the long strip of the insulating sheet raw material with the self-adhesive layer, and can continue to move forward with the long strip of raw material, so that Fang Boyi can continuously stamp the raw material of the insulating sheet, greatly improving work efficiency.

[0023] The following is an explanation and description of the technical solutions of the embodiments of the present invention in conjunction with the drawings of the embodiments of the present invention, but the following embodiments are only preferred embodiments of the present invention and are not exhaustive. Based on the embodiments in the embodiments, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention.
[0024] The following describes in detail an automatic demoulding structure of a stamping die for an insulating sheet according to an embodiment of the present invention with reference to the accompanying drawings.
[0025] Example 1
[0026] For easier understanding, see Figures 1 to 4 The utility model provides an embodiment of an automatic demoulding structure of a stamping die for an insulating sheet, comprising a die plate 1, a plurality of cutter heads 2 fixedly mounted on the bottom of the die plate 1, and a synchronous demoulding component and an anti-slip component provided on the die plate 1;
[0027] The synchronous demoulding assembly includes several slide bars 301, a fixed plate 302, a pressure plate 303, a synchronous return spring 304, several knife inlets 305 and several ejector rods 306. Several slide bars 301 are slidably connected to the four corners of the mold plate 1, the fixed plate 302 is fixedly installed at the top end of the slide bar 301, the pressure plate 303 is fixedly installed at the bottom end of the slide bar 301, the synchronous return spring 304 is sleeved on the outside of the slide bar 301, several knife inlets 305 are opened in the middle of the pressure plate 303, and several ejector rods 306 are installed. One end of a push rod 306 is fixedly installed on the bottom of the fixed plate 302, one end of the synchronous return spring 304 is against the bottom surface of the mold plate 1, and the other end of the synchronous return spring 304 is against the top surface of the pressure plate 303. The diameter of the cutting edge 305 is larger than the diameter of the cutter head 2, and the cutting edge 305 is sleeved on the outside of the cutter head 2. The bottom height of the cutting edge 305 is 0.3-0.4 cm lower than the bottom height of the cutter head 2. One end of the push rod 306 is sleeved on the inside of the cutter head 2, and the diameter of the push rod 306 matches the inner diameter of the cutter head 2.
[0028] It should be noted that by providing a pressure plate 303 and a push rod 306, while the knife is lifted after stamping, the pressure plate 303 and the push rod 306 press down the stamped insulating sheet under the elastic force of the synchronous return spring 304, so that the insulating sheet is separated from the knife head 2 and remains on the long strip of insulating sheet raw material with the self-adhesive layer. The stamped insulating sheet can continue to move forward with the long strip of raw material, so that Fang Boyi can continuously stamp the raw material of the insulating sheet, greatly improving work efficiency.
[0029] Example 2
[0030] In some embodiments, as Figure 4 As shown, the anti-slip component includes a panel 401 and several anti-slip particles 402. The panel 401 is fixedly connected to the bottom of the pressure plate 303, and the several anti-slip particles 402 are fixedly connected to the bottom of the panel 401. The panel 401 and the anti-slip particles 402 are both made of rubber, and the bottom height of the top rod 306 is the same as the bottom height of the panel 401.
[0031] It should be noted that by setting the panel 401 and the anti-slip particles 402, the panel 401 made of rubber material will press the raw material, and the anti-slip particles 402 will increase the friction coefficient between the mold and the raw material, preventing the raw material from being pulled during stamping and causing displacement, thereby ensuring the quality of the stamped insulating sheet. The purpose of the bottom height of the top rod 306 being the same as the bottom height of the panel 401 is to ensure that the top rod 306 can simultaneously leave the insulating sheet together with the panel 401 when resetting, ensuring that the insulating sheet can stay in its original position normally to ensure the continuity of work.
[0032] Working principle: When in use, the rolled insulating sheet raw material with a self-adhesive layer is unfolded and placed under the stamping die. The raw material is unrolled and dragged one end of the raw material by hand or machine to unfold it forward. At the same time, the die plate 1 is used to drive the cutter head 2 to press down for stamping. The panel 401 made of rubber material will press the raw material, and the anti-slip particles 402 will increase the friction coefficient between the die and the raw material to prevent the raw material from being pulled during stamping. The insulating sheet raw material with a self-adhesive layer can be punched out to the size of the battery end face. After stamping, when the knife is lifted, the pressing plate 303 and the push rod 306 press down the stamped insulating sheet under the elastic force of the synchronous return spring 304, so that the insulating sheet is separated from the cutter head 2 and remains on the long strip of the insulating sheet raw material with the self-adhesive layer. The stamped insulating sheet can continue to move forward with the long strip of raw material, so that Fang Boyi can continuously stamp the raw material of the insulating sheet, greatly improving work efficiency.
[0033] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
