[0002] In the electronics manufacturing industry, copper foil is widely used as an important conductive material in various electronic devices. In particular, adhesive-coated copper foil is widely used in the manufacture of flexible circuit boards, lithium-ion batteries and other fields due to its excellent conductivity, adhesion and processing performance. In the punching process of adhesive-coated copper foil, holes are often processed by mold workpieces.

[0003] For example, the patent with publication number CN 220297308 U (a copper foil stamping die): includes a bracket and a copper foil, a lifting component is installed on the bracket, and further includes: a stamping die that can be adjusted according to the position of the opening on the copper foil, the stamping die is disposed on the bracket, the lifting component includes: a box body, the box body is fixedly installed on the top of the bracket, and the hydraulic cylinder is fixedly installed on the inner wall of the box body;

[0004] While the aforementioned existing technology can adjust the position of the stamping block according to the position of the opening on the copper foil, it does so by rotating a screw.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figure 1-4 This utility model provides an embodiment of a mold workpiece suitable for punching copper foil containing adhesive, including an upper mold 1, a lower mold 2 below the upper mold 1, an upper mold cavity 101 inside the upper mold 1, a horizontal plate 9 fixedly installed inside the upper mold cavity 101, an mounting plate 10 below the horizontal plate 9, a punching head 8 fixedly installed below the mounting plate 10, the mounting plate 10 is configured as a U-shaped plate, a fixing bolt 11 is provided inside the mounting plate 10, and an elongated hole 902 is provided inside the horizontal plate 9. The horizontal plate 9 and the mounting plate 10 are fixedly connected by the fixing bolt 11. The U-shaped mounting plate 10 is clipped onto the horizontal plate 9, and the screw of the fixing bolt 11 passes through the elongated hole 902 to fix the horizontal plate 9 and the mounting plate 10. The position of the punching head 8 can be adjusted by sliding the mounting plate 10 by loosening the fixing bolt 11. At the same time, the U-shaped mounting plate 10 also makes it easy to increase or decrease the number of mounting plates 10 with punching heads 8.

[0024] By using a horizontal plate 9 and a mounting plate 10, with an elongated hole 902 on the horizontal plate 9 and the mounting plate 10 securely connected to the horizontal plate 9 by fixing bolts 11, the position adjustment of the punching head 8 becomes flexible, enabling it to meet the opening requirements of different positions and densities on the adhesive-containing copper foil. It also effectively avoids the problem of punching position deviation caused by sliding in the traditional screw adjustment method, ensuring the punching accuracy. At the same time, the U-shaped mounting plate structure design makes it easy to increase or decrease the number of punching heads 8 according to needs without a complicated disassembly and reassembly process, thereby significantly improving the adaptability and practicality of the mold and facilitating the punching processing of adhesive-containing copper foil.

[0025] Furthermore, a lower mold cavity 201 is provided at the upper part of the lower mold 2, a template 13 is provided inside the lower mold cavity 201, a punching hole 1301 is provided inside the template 13, and a slot 202 is provided inside the lower mold 2 along the lower part of the lower mold cavity 201, and the slot 202 is connected to the lower mold cavity 201.

[0026] The design of the punching hole 1301 ensures that the punching head 8 can stably punch the copper foil containing adhesive, while the connection between the slot 202 and the lower die cavity 201 facilitates the discharge of waste, maintains the smoothness of the punching process, and improves the punching efficiency.

[0027] Furthermore, a top plate 3 is provided above the upper mold 1, and a hydraulic cylinder 6 is fixedly installed in the middle above the top plate 3. The hydraulic cylinder 6 is externally connected to an oil pumping device, and the piston rod end of the hydraulic cylinder 6 slides through the top plate 3 and is fixedly connected to the upper mold 1.

[0028] The hydraulic cylinder 6 provides a stable driving force, ensuring that the upper die 1 can move up and down, facilitating the punching of the copper foil containing adhesive.

[0029] Furthermore, guide rods 7 are symmetrically arranged on both sides of the hydraulic cylinder 6, and the lower end of the guide rod 7 slides through the top plate 3 and is fixedly connected to the upper mold 1.

[0030] The guide rod 7 guides the upper die 1, ensuring the stability of the upper die 1 during the descent process and improving the accuracy of the copper foil punching.

[0031] Furthermore, upright plates 12 are symmetrically fixedly installed on both sides below the lower mold 2, and a bottom plate 5 is fixedly installed below the upright plates 12. Support plates 4 are symmetrically fixedly installed on both sides between the top plate 3 and the bottom plate 5.

[0032] The vertical plate and bottom plate symmetrically fixedly installed below the lower die 2, and the support plate structure symmetrically fixedly installed between the top plate and the bottom plate, together form a stable frame for the die workpiece, ensuring the overall stability of the die during the punching process and preventing die damage or reduction in punching accuracy caused by vibration or impact.

[0033] Furthermore, a scale line 901 is provided on the front end surface of the horizontal plate 9.

[0034] The setting of scale line 901 provides operators with an intuitive reference, enabling them to adjust the position of the punch head 8 more accurately, thus increasing its practicality.

[0035] Working principle: During use, the copper foil containing adhesive is placed on the upper and lower molds 2. The upper mold 1 is moved up and down by the piston rod of the hydraulic cylinder 6 driven by the hydraulic cylinder 6, which works with the lower mold 2 to complete the punching of the copper foil containing adhesive. The waste generated by punching is discharged through the slot 202 to keep the punching process smooth. Inside the upper mold 1, the horizontal plate 9 is firmly connected to the mounting plate 10 through the elongated hole 902 and the fixing bolt 11. The punching head 8 below the mounting plate 10 is aligned with the punching hole 1301 of the template 13 in the lower mold 2 to punch. The setting of the scale line 901 provides the operator with a visual reference for position adjustment, which is conducive to the accuracy of the position adjustment of the punching head 8.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
