[0033] The present application provides a compression mold 10.

[0034] Please refer to Figure 1 and Figure 2 In an embodiment of the present application, the compression mold 10 includes two mold assemblies 100, the mold assembly 100 includes a first plate 110 and a second plate 120, two second plates 120 are arranged between two first plates 110, and at least one second plate 120 is formed with a cavity 121 and is detachably connected with the adjacent first plate 110.

[0035] Specifically, the compression mold 10 is used for compressing a laminated busbar 20, the laminated busbar 20 is clamped between two mold assemblies 100 and accommodated in the cavity 121, so as to compress a plurality of conductive plates (metal plates 201 such as copper or aluminum) of the laminated busbar 20 together with the insulating material (insulating film 202) according to a specific arrangement to form an integral structure.

[0036] The first plate 110 serves as an outer structure of the compression mold 10, and is used to provide mechanical support and help transmit pressure. The first plate 110 can be made of metal such as aluminum or aluminum alloy, and is processed by a milling machine or a machining center. The first plate 110 has good thermal conductivity, light weight, and easy processing, so that the quality of the hot-pressed product is relatively stable. The two surfaces of the first plate 110 in the thickness direction are flat, and the flatness is less than 0.05 mm. The high flatness of the surface can ensure the close fit between the first plate 110 and the second plate 120, reduce the gap and looseness, and thus improve the stability and reliability of the overall structure; it can ensure that the applied pressure can be evenly distributed, avoid local stress concentration, and reduce the risk of deformation and damage; it can ensure the maximization of the contact surface between the first plate 110 and the second plate 120, improve the heat transfer or conduction efficiency, and thus further improve the stability of the quality of the hot-pressed product.

[0037] The two second plates 120 are arranged between the two first plates 110. The second plate 120 is used to process a cavity 121 conforming to the specific shape of the laminated busbar 20. The laminated busbar 20 is accommodated in the cavity 121, and the precise molding of the laminated busbar 20 can be realized. The second plate 120 can be made of aluminum plate or aluminum alloy and processed by laser cutting. The second plate 120 has low manufacturing cost and short processing cycle.

[0038] At least one second plate 120 is formed with a cavity 121, and the cavity 121 penetrates through the two opposite surfaces of the second plate 120. The second plate 120 formed with the cavity 121 is detachably connected with the adjacent first plate 110. The second plate 120 is convenient to replace, so that the mold assembly 100 has high flexibility. The second plate 120 can be quickly replaced according to different product requirements, so as to adapt to the production requirements of laminated busbars 20 of different specifications or shapes, and reduce the production preparation time and cost. The detachable connection between the first plate 110 and the second plate 120 also improves the convenience of maintenance and part replacement of the mold assembly 100. When the second plate 120 is worn or damaged, it can be directly replaced without replacing the entire compression mold 10, thereby reducing the maintenance cost and improving the utilization rate of the first plate 110.

[0039] The technical scheme of the present application forms at least one second plate 120 with a cavity 121, and detachably connects the second plate 120 with the adjacent first plate 110. The second plate 120 with low manufacturing cost and easy processing can be replaced according to the production requirements of the laminated busbar 20. The flexibility of the compression mold 10 is improved, and the utilization rate of the first plate 110 is also improved, thereby reducing the manufacturing cost of the compression mold 10, greatly shortening the processing cycle of the compression mold 10, and enhancing the response production capacity.

[0040] In an embodiment, please refer to Figure 2The mold assembly 100 further comprises a spacer plate 130 arranged between the first plate 110 and the second plate 120.

[0041] The spacer plate 130 is also detachably connected with the first plate 110 and the second plate 120, and the spacer plate 130, the first plate 110 and the second plate 120 can be replaced. The spacer plate 130 can be made of aluminum plate or aluminum alloy and other metals and processed by laser cutting. The spacer plate 130 has low manufacturing cost and short processing cycle. The spacer plate 130 can make the connection between the first plate 110 and the second plate 120 more convenient. When the second plate 120 needs to be replaced, the spacer plate 130 can be used as an intermediate medium to reduce the direct contact between the first plate 110 and the second plate 120, which not only facilitates the replacement operation, but also reduces the wear of the first plate 110. In addition, the spacer plate 130 can help compensate for the manufacturing tolerance or assembly error between the first plate 110 and the second plate 120, ensuring a tight fit between the two, thereby improving the forming precision and product quality; can play a buffering role in the pressing process, absorb part of the pressure fluctuation, protect the mold from excessive impact force, and help prolong the service life of the mold; by selecting different hardness or thickness of the spacer plate 130 material, the pressure distribution applied on the laminated busbar 20 can be adjusted to make the pressure more uniform, avoiding product defects caused by local overpressure.

[0042] In an embodiment, referring to Figure 2 The two second plates 120 are formed with cavities 121, and each second plate 120 is detachably connected with the adjacent first plate 110.

[0043] The two second plates 120 are formed with cavities 121, and the cavities 121 formed by the two second plates 120 are consistent in shape and size, and the two cavities 121 are mirror image arranged. The laminated busbar 20 is partially accommodated in one of the cavities 121 and partially accommodated in the other cavity 121. Each second plate 120 is detachably connected with the adjacent first plate 110, further improving the flexibility of the pressing mold 10, and the two first plates 110 can be reused, further reducing the manufacturing cost of the pressing mold 10, greatly shortening the processing cycle of the pressing mold 10, and enhancing the response production capacity.

[0044] In other embodiments, one of the second plates 120 is formed with a cavity 121, and the second plate 120 is detachably connected with the adjacent first plate 110; the other second plate 120 is not provided with a cavity 121 and has a complete plane, and the second plate 120 can be detachably connected with the adjacent first plate 110, or fixedly connected with the adjacent first plate 110, or integrally formed with the adjacent first plate 110.

[0045] In an embodiment, referring to Figure 2 The thickness of the first plate 110 is greater than the thickness of the second plate 120.

[0046] The thicker first plate 110 can withstand greater mechanical stress and wear, has a longer service life, can reduce the production demand of the first plate 110, and thus shorten the processing cycle of the press-fit mold 10. In addition, the thicker first plate 110 provides higher structural rigidity and stability, can better withstand the high pressure generated during the press-fit process, reduces the risk of deformation, ensures the accuracy and reliability of the press-fit mold 10 during long-term work; can more effectively transfer heat, ensure uniform distribution of the internal temperature of the entire press-fit mold 10, help to speed up the heating process, shorten the curing time, and reduce the deformation or defects of the laminated busbar 20 caused by uneven temperature; can provide additional safety protection during the press-fit process, prevent mold rupture or failure caused by accidental overload or operation errors, and protect the safety of operators and equipment.

[0047] In an embodiment, referring to Figure 1 and Figure 2 , the mold assembly 100 is provided with a connecting hole 140 penetrating along the thickness direction thereof, and the press-fit mold 10 further comprises a fastener 200 arranged in the connecting hole 140, and the second plate 120 is detachably connected with the adjacent first plate 110 through the fastener 200.

[0048] The connecting hole 140 is partially formed in the first plate 110 and partially formed in the second plate 120. The axis direction of the connecting hole 140 is consistent with the thickness direction of the mold assembly 100. By arranging the fastener 200 (such as a bolt, a nut, etc.) in the connecting hole 140, the second plate 120 and the first plate 110 can be connected to ensure the close fit therebetween and prevent displacement or loosening due to external force during the press-fit process. The use of the fastener 200 makes the disassembly of the second plate 120 simple and fast. When the second plate 120 is damaged or worn, the fastener 200 can be removed to disassemble the first plate 110 and the second plate 120, and the damaged second plate 120 can be directly replaced without replacing the entire mold assembly 100. The detachable connection of the second plate 120 with the adjacent first plate 110 not only improves the stability of the overall structure of the mold assembly 100, but also improves the convenience of replacing the second plate 120.

[0049] In other embodiments, the first plate 110 and the second plate 120 can also be detachably connected by clamping, adhesive or double-sided tape, etc.

[0050] In an embodiment, referring to Figure 5The mold assembly 100 further comprises a spacer plate 130 arranged between the first plate 110 and the second plate 120, the connecting hole 140 comprises a first hole section 141 and a second hole section 142, the first hole section 141 is formed on the first plate 110, the second hole section 142 is formed on the second plate 120 and the spacer plate 130, the fastener 200 comprises a column 210 and a head 220, the column 210 is locked with the first hole section 141, and the head 220 abuts against the edge of the second hole section 142.

[0051] The head 220 is arranged at one end of the column 210, and the diameter of the head 220 is greater than that of the column 210. The column 210 is directly locked with the first hole section 141 of the first plate 110, which ensures that the fastener 200 can be firmly fixed on the thicker first plate 110; the head 220 abuts against the edge of the second hole section 142, i.e. the head 220 abuts against the side of the second plate 120 away from the first plate 110, and presses the second plate 120, so that the first plate 110 and the second plate 120 can be tightly connected, preventing loosening under high pressure or high temperature conditions.

[0052] In other embodiments, the fastener 200 is screwed with the first plate 110 and the second plate 120, respectively.

[0053] In an embodiment, referring to Figure 5 The diameter of the second hole section 142 is greater than that of the first hole section 141, the connection between the first hole section 141 and the second hole section 142 is formed with a first positioning surface 143, the outer peripheral wall of the column 210 is formed with a second positioning surface 211 corresponding to the first positioning surface 143, and the first positioning surface 143 abuts against the second positioning surface 211.

[0054] The abutment between the first positioning surface 143 and the second positioning surface 211 ensures the accurate alignment between the fastener 200 and the connecting hole 140, avoiding the possible deviation or misalignment problem in the installation process, thereby improving the relative position accuracy between the first plate 110 and the second plate 120, and further ensuring the accurate positioning of the cavity 121 of the two mold assemblies 100, and ensuring the yield rate of the laminated busbar 20 after pressing.

[0055] In other embodiments, the first positioning surface 143 is formed on the inner peripheral wall of the first hole section 141, or on the inner peripheral wall of the second hole section 142.

[0056] In an embodiment, referring to Figure 1 and Figure 6 Each mold assembly 100 is further provided with a first avoiding hole 150, the first avoiding hole 150 is arranged corresponding to the connecting hole 140 of the other mold assembly 100, the column 210 is locked in the connecting hole 140, and the head 220 is accommodated in the first avoiding hole 150.

[0057] The first avoiding hole 150 ensures that the head 220 of the fastener 200 will not interfere with other components of the adjacent mold assembly 100, avoiding damage to the mold assembly 100 during the pressing process. The first avoiding hole 150 also ensures accurate alignment between two mold assemblies 100, improving the overall positioning accuracy of the pressing mold 10. The first avoiding hole 150 can pass through the first plate 110, the second plate 120, and the backing plate 130 in the thickness direction of the mold assembly 100, or it can only pass through the second plate 120 and the backing plate 130.

[0059] The cooperation of the guide column 300 and the guide hole 162 can ensure accurate alignment of the two mold assemblies 100 during pressing, avoiding product quality problems caused by positional deviation. Each time the mold is opened and closed, the cooperation of the guide column 300 and the guide hole 162 can ensure that the mold assembly 100 returns to the same position, ensuring the stability and consistency of production. The cooperation of the guide column 300 and the guide hole 162 makes the installation of the mold assembly 100 more intuitive and simple, and the operator only needs to align the guide column 300 with the guide hole 162 to complete the preliminary positioning, reducing the assembly time and difficulty. The guide column 300 can be made of high-strength, wear-resistant materials such as stainless steel or hardened steel.

[0060] In an embodiment, please refer to Figure 1 and Figure 6 One of the mold assemblies 100 is provided with a first mounting hole 161 that passes through its thickness direction, and the first mounting hole 161 is arranged corresponding to the guide hole 162, and the guide column 300 is installed in the first mounting hole 161.

[0061] The first mounting hole 161 passes through the first plate 110, the second plate 120, and the backing plate 130. The guide column 300 is inserted into the first mounting hole 161, and the guide column 300 can be interference fit with the first mounting hole 161, or it can be pressed into the first mounting hole 161. When the guide column 300 breaks, a new guide column 300 can be replaced in the first mounting hole 161 without affecting the use of the first plate 110.

[0062] In other embodiments, the guide column 300 can also be welded or integrally formed with the first plate 110.

[0063] In an embodiment, please refer to Figure 5 A guide sleeve 400 is arranged in the guide hole 162.

[0064] The guide sleeve 400 can be made of wear-resistant and high-temperature-resistant material. The guide sleeve 400 is installed in the guide hole 162 and used for guiding and protecting the guide column 300. The guide sleeve 400 provides more stable support for the guide column 300, prevents deviation during the pressing of the pressing mold 10, ensures uniform distribution of pressure, effectively reduces vibration of the mold during pressing, and improves the forming quality of the laminated busbar 20. The guide sleeve 400 directly contacts the guide column 300, reduces friction between the guide column 300 and the guide hole 162, reduces the possibility of mutual wear, and prolongs the service life.

[0066] The second avoiding hole 171 penetrates the gasket plate 130 and the second plate 120 along the thickness direction of the mold assembly 100. The positioning pin is used for positioning the position of the laminated busbar 20, and also plays a role in positioning the two mold assemblies 100, avoiding product quality problems caused by position deviation. The positioning pin can position the laminated busbar 20 each time the pressing is performed, ensuring the stability and consistency of production and reducing the scrap rate. The positioning pin can be made of steel or other metals.

[0067] In an embodiment, referring to Figure 2 and Figure 3 One of the mold assemblies 100 is provided with a second mounting hole 172, which is correspondingly arranged with the second avoiding hole 171, and the positioning pin is riveted and connected with the second mounting hole 172.

The positioning pin comprises a riveting section and a positioning section. The riveting section is riveted to the second mounting hole 172 on the gasket plate 130 and is in interference fit with the second mounting hole 172. The positioning section is used for penetrating the laminated busbar 20 and being accommodated in the second avoiding hole 171. The riveting and interference fit of the positioning pin with the second mounting hole 172 makes the positioning pin not easy to fall off, break or skew, the service life of the second plate 120 is longer, the positioning connection of the positioning pin is more reliable, the stability of the product is better, and thus the service life of the mold and the quality of the hot-pressed product are improved.

[0069] In other embodiments, the positioning pin is in interference fit with the second mounting hole 172; or the positioning pin is integrally formed with the gasket plate 130.
