Description

TECHNICAL FIELD

[0001] The utility model relates to a shell punching mould technical field especially relates to a general type shell punch, shell concave die and shell mould. BACKGROUND

[0002] Lithium ion batteries are widely used in portable electronic devices such as mobile phones, digital cameras and laptop computers due to their high specific energy, long cycle life and long storage time. They are also widely used in electric vehicles, electric bicycles and electric tools.

[0003] In the production process of lithium ion polymer soft package batteries, the punch structure formed on the surface of the aluminum plastic film is manufactured by a shell punching mould through a stamping process.

[0004] Currently, the traditional method commonly used in the industry is to customize a set of shell punching mould for each battery model to ensure that aluminum plastic films with different size punch structures can be produced to form a shell for packaging the battery cell.

[0065] Embodiment one

[0066] In view of the defects of the prior art, the present applicant, based on many years of rich practical experience and professional knowledge in designing and manufacturing such products, and with the use of theory, actively researches and innovates, in the hope of creating a technology that can solve the defects in the prior art. After continuous research, design, and repeated trial of samples and improvement, the present utility model is finally created, which has practical value.

[0067] Please refer to Figures 1-2 The utility model embodiment provides a general type shell punch, including punch base plate 1 and punch mold core 2, wherein,

[0068] The punch base plate 1 includes punch base plate body 11 and punch base block 12.

[0069] The punch base substrate body 11 is provided with a first installation cavity 13;

[0070] The punch base block 12 is movably arranged in the first installation cavity 13 to form a first through hole 14 in cooperation with the first installation cavity 13; when the punch base block 12 moves relative to the punch base substrate body 11, the size of the first through hole 14 changes.

[0071] The first through hole 14 is provided with the punch mold core 2.

[0072] It should be noted that, compared with the traditional integral design, one of the great innovations of the present embodiment is that the punch base substrate 1 component is divided into two independent but mutually cooperative parts, namely the punch base substrate body 11 and the punch base block 12, and the structural mechanism of the movable punch base block 12 in the first installation cavity 13 is creatively introduced. This design makes it possible for the operator to quickly and accurately adjust the size of the first through channel 14 by adjusting the relative position between the punch base block 12 and the punch base substrate body 11, so as to perfectly adapt to punch mold cores 2 of various sizes when the production demand changes and different sizes of punch mold cores 2 are needed to manufacture different sizes of impact pits. This improvement not only significantly improves the versatility and flexibility of the mold, but also effectively reduces the cost of frequent mold replacement, further shortens the development cycle of the mold, and has immeasurable positive impact on the production efficiency and market promotion of soft package batteries.

[0073] Please refer again to Figures 1-2 In an embodiment of the present embodiment, the universal shell punch further comprises a first distance adjusting screw 3.

[0074] The punch base block 12 is movably arranged in the first installation cavity 13 through the first distance adjusting screw 3.

[0075] It should be noted that the punch base block 12 realizes flexible and stable movement in the first installation cavity 13 with the help of the first distance adjusting screw 3. The first distance adjusting screw 3 is designed ingeniously and accurately, which not only ensures that the punch base block 12 can smoothly move along the preset path when needed to change the size of the first through channel 14, but also firmly locks the position of the punch base block 12 when necessary to ensure the stability and accuracy of the mold during the stamping process.

[0076] This design not only enhances the versatility and flexibility of the mold, but also ensures the stability and durability of the mold during long-term use. By simply rotating the first distance screw 3, the operator can quickly and accurately adjust the position of the male die base block 12, thereby adapting to different sizes of male die cores, greatly improving production efficiency and mold utilization, and also bringing more convenience and cost advantages to the production of soft-pack batteries.

[0077] In one embodiment of the present embodiment, the male die base plate body 11 and the male die base block 12 are both provided with screw holes for the first distance screw 3 to pass through.

[0078] It should be noted that this design allows the first distance screw 3 to pass from one side of the male die base plate body 11 and pass through the screw hole on the male die base block 12, and finally be fixed on the other side by a nut or other fastener. Through such an installation method, the first distance screw 3 not only plays a connecting and fixing role, but more importantly, it becomes a key tool for adjusting the position of the male die base block 12 in the first mounting cavity 13.

[0079] When it is necessary to adjust the position of the male die base block 12 to adapt to different sizes of male die cores, the operator can simply loosen or tighten the first distance screw 3, causing it to rotate or move within the screw hole, thereby causing the male die base block 12 to displace accordingly within the first mounting cavity 13. Once the desired size adjustment is achieved, the first distance screw 3 can be tightened again to ensure the stability and accuracy of the male die base block 12 during the stamping process.

[0080] This design not only improves the versatility and flexibility of the mold, but also ensures the stability and durability of the mold during long-term use, providing strong technical support for the efficient production of soft-pack batteries.

[0081] In one embodiment of the present embodiment, the design of the male die base block 12 presents a high degree of flexibility and diversity. Specifically, the number of male die base blocks 12 is set to at least one, which means that the number of male die base blocks 12 can be flexibly selected according to actual production needs to meet the manufacturing requirements of different sizes and shapes of stamping pits. More advanced is that the shapes of these male die base blocks 12 can be the same or different, which provides great flexibility and customization space for mold design.

[0082] At the same time, the design of the first mounting cavity 13 also corresponds to it, and the number is also set to at least one to accommodate and support the corresponding number of male die base blocks 12. This design allows the mold to quickly and easily replace or adjust the male die base block 12 during different production stages or for different production needs, thereby achieving quick adaptation and efficient utilization of the mold.

[0083] In a further design, at least one punch base block 12 is provided with a second through-hole 15. This hole is designed to accommodate and secure the punch core 2, ensuring its stability during the stamping process and achieving the desired stamping effect.

[0084] With this design, when different sizes or shapes of stamping pits need to be manufactured, the operator can simply replace or adjust the punch base block 12 and the second through-hole 15 that matches it, and then insert the punch core 2 of the corresponding size. This process is not only fast and easy, but also greatly improves the versatility and production efficiency of the mold, bringing significant convenience and cost advantage to the production of soft-pack batteries.

[0085] Please refer to Figures 1-2 again, and in conjunction with Figures 3-4 In one embodiment of the present embodiment, the number of punch cores 2 is set to at least one, which provides great convenience for customized production of the mold. More importantly, these punch cores 2 can be the same or different in shape, as shown in Figure 3 and Figure 4 They each present a unique geometric shape to meet the manufacturing needs of stamping pits of different sizes and shapes.

[0086] This design not only improves the versatility of the mold, allowing the same mold to adapt to a variety of different production needs, but also greatly enriches the shape and size options of the stamping pit, providing more possibilities and creative space for the design and production of soft-pack batteries.

[0087] In actual operation, the operator can select the punch core 2 with the appropriate shape and size according to the specific production needs and insert it into the first through-hole 14 and the second through-hole 15 on the punch base block 12.

[0088] In summary, the design of the punch core 2 in the present embodiment not only improves the versatility and production efficiency of the mold, but also brings significant convenience and cost advantage to the production of soft-pack batteries, while also setting a new benchmark for the mold design industry.

[0089] Figure 5 is a structural schematic diagram of an aluminum-plastic film stamped by the universal shell-punching punch. In this schematic diagram, the stamping pits formed on the aluminum-plastic film after precise stamping can be clearly observed. The shape, size, and arrangement of these stamping pits strictly follow the production requirements, demonstrating the high precision and flexibility of the universal shell-punching punch in the manufacturing process.

[0090] Notably, due to the split design and adjustable screw mechanism of the universal shell-punching punch, the mold can easily adapt to punch cores of different sizes and shapes, achieving customized stamping of the punch on the aluminum-plastic film. This design not only improves production efficiency and reduces mold cost, but also brings unprecedented flexibility and diversity to the production of soft-pack batteries.

[0091] Through the display of Figure 5 , the excellent performance of the universal shell-punching punch in the aluminum-plastic film stamping process can be intuitively felt, as well as its positive impact on the production of soft-pack batteries. This innovative design will undoubtedly promote the further development of soft-pack battery manufacturing technology, injecting new vitality into the technological progress and product upgrading of the industry.

[0092] Although the terms punch, core, mounting cavity, etc. are used more in this application, the possibility of using other terms is not excluded. The use of these terms is only to facilitate the description and explanation of the essence of the utility model; any additional limitation is contrary to the spirit of the utility model.

[0093] The universal shell-punching punch provided by the embodiment of the utility model, including punch base plate and punch core, through the punch base plate of originally integral design is improved to split design, namely including punch base plate ontology and punch base block, then design punch base block movably set in first mounting cavity of punch base plate ontology, make punch base block can form first through hole that can be provided punch core to wear with first mounting cavity cooperation, when need to use punch core of different size, to manufacture punch pit of different size, only need to use relative activity of punch base block and punch base plate ontology, change the size of first through hole can adapt to punch core of different size, realized the purpose of mold universal, not only can save the cost of mold opening, but also shorten the mold opening cycle, be favorable to the production and popularization of soft-pack battery.
