[0061] The present invention will be further described below with reference to the accompanying drawings.

[0062] Stamping equipment is a type of processing equipment that can process materials into parts. By applying pressure to the material on a stamping die, it causes deformation and completes the shaping process, thereby obtaining the desired part. With the diversification of products and the updating of models, the number of stamping dies corresponding to the same product also increases. For example, the position of the compressor on the chassis inside an air conditioner varies depending on the requirements of the internal structure of the air conditioner, resulting in multiple models of the corresponding chassis. The shape of the ribs on the chassis also varies depending on the model. Therefore, in order to meet the processing requirements of different models of the same product, multiple sets of stamping dies need to be made. This not only increases production costs but also increases the number of die changes and the time spent in production.

[0063] Example 1

[0064] like Figures 1-3As shown, to solve the above-mentioned technical problems, this utility model embodiment provides a mold structure, including a lower mold assembly 10, a positioning assembly 20, and an upper mold assembly 30; the lower mold assembly 10 includes a lower main body 110 and a lower mold rib insert 120, the lower mold rib insert 120 being detachably disposed on the lower main body 110; the positioning assembly 20 is movably disposed on the lower mold assembly 10, and the positioning assembly 20 is configured to be able to position the workpiece to be stamped and move relative to the lower mold assembly 10 in the height direction; the upper mold... Component 30 includes an upper main body 310 and an upper die pressing rib insert 320. The upper die pressing rib insert 320 is detachably disposed on the upper main body 310. The upper main body 310 is configured to move along the height direction so that the upper die pressing rib insert 320 and the corresponding lower die pressing rib insert 120 can press the workpiece to be stamped. The positioning component 20 is provided with positioning holes 210, which correspond one-to-one with the lower die pressing rib inserts 120 so that the corresponding lower die pressing rib inserts 120 can pass through.

[0065] As can be seen from the above, by detachably setting the lower mold rib insert 120 to the lower main body 110 and the upper mold rib insert 320 to the upper main body 310, users can quickly replace the rib inserts according to the product model to adapt to different processing requirements without replacing the entire mold. Compared with traditional molds that are designed for a single model, this utility model allows for the replacement of the upper mold rib insert 320 and the lower mold rib insert 120 according to the product model, thereby adjusting the position and shape of the mold core and realizing the reuse of the mold. This not only improves the versatility and utilization rate of the mold, but also reduces production costs, increases production efficiency, and achieves compatibility with multiple product models. By setting a positioning component 20 that can move along the height direction relative to the lower die assembly 10, not only can the part to be stamped be placed, but it can also play a stripping role to ensure smooth demolding. In addition, the positioning component 20 plays a positioning role for the part to be stamped, and the movable connection between the positioning component 20 and the lower die assembly 10 allows the user to quickly replace the positioning component 20 according to the product model to adapt to different processing requirements. It ensures that the positioning hole 210 corresponds one-to-one with the lower die pressure rib insert 120, so that the positioning component 20 can adapt to different die core positions, thereby improving the flexibility of the positioning component 20 and the versatility of the mold.

[0066] It should be noted that, as Figure 1 As shown, the height direction is parallel to the Z direction; the upper mold rib insert 320 and the lower mold rib insert 120 correspond one-to-one.

[0067] It should also be noted that the part to be stamped is the chassis 1 of an air conditioning compressor. The chassis 1 has multiple bolt holes 2, which are evenly spaced around the same center point, and each bolt hole 2 is near a pressure rib. The bolt holes 2 and pressure ribs are obtained by stamping the machined holes on the part to be stamped using an upper die pressure rib insert 320 and a corresponding lower die pressure rib insert 120. The number of bolt holes 2 is the same as the number of lower die pressure rib inserts 120. Furthermore, for different models of chassis 1, the positions of the bolt holes 2, the positions of the pressure ribs, and the shapes of the pressure ribs are different. By changing the upper die pressure rib insert 320 and the lower die pressure rib insert 120, stamping different models of chassis 1 can be completed. For example, as... Figure 18 As shown, there are three bolt holes 2, and there are also three upper mold pressing rib inserts 320 installed on the upper main body 310 and three lower mold pressing rib inserts 120 installed on the lower main body 110.

[0068] Example 2

[0069] like Figures 1-3 As shown, the mold structure includes a lower mold assembly 10, a positioning assembly 20, and an upper mold assembly 30. The lower mold assembly 10 includes a lower main body 110 and a lower mold rib insert 120, which is detachably disposed on the lower main body 110. The positioning assembly 20 is movably disposed on the lower mold assembly 10 and is configured to position the workpiece to be stamped and move relative to the lower mold assembly 10 in the height direction. The upper mold assembly 30 includes an upper main body 310 and an upper mold rib insert 320, which is detachably disposed on the upper main body 310 and is configured to move in the height direction so that the upper mold rib insert 320 and the corresponding lower mold rib insert 120 stamp the workpiece to be stamped. The positioning assembly 20 is provided with positioning holes 210, which correspond one-to-one with the lower mold rib inserts 120, so that the corresponding lower mold rib inserts 120 can pass through.

[0070] As can be seen from the above, by detachably setting the lower mold rib insert 120 to the lower main body 110 and the upper mold rib insert 320 to the upper main body 310, users can quickly replace the rib inserts according to the product model to adapt to different processing requirements without replacing the entire mold. Compared with traditional molds that are designed for a single model, this utility model allows for the replacement of the upper mold rib insert 320 and the lower mold rib insert 120 according to the product model, thereby adjusting the position and shape of the mold core and realizing the reuse of the mold. This not only improves the versatility and utilization rate of the mold, but also reduces production costs, increases production efficiency, and achieves compatibility with multiple product models. By setting a positioning component 20 that can move along the height direction relative to the lower die assembly 10, not only can the part to be stamped be placed, but it can also play a stripping role to ensure smooth demolding. In addition, the positioning component 20 plays a positioning role for the part to be stamped, and the movable connection between the positioning component 20 and the lower die assembly 10 allows the user to quickly replace the positioning component 20 according to the product model to adapt to different processing requirements. It ensures that the positioning hole 210 corresponds one-to-one with the lower die pressure rib insert 120, so that the positioning component 20 can adapt to different die core positions, thereby improving the flexibility of the positioning component 20 and the versatility of the mold.

[0071] It should be noted that, as Figure 1 As shown, the height direction is parallel to the Z direction; the upper mold rib insert 320 and the lower mold rib insert 120 correspond one-to-one.

[0072] It should also be noted that the part to be stamped is the chassis 1 of an air conditioning compressor. The chassis 1 has multiple bolt holes 2, which are evenly spaced around the same center point, and each bolt hole 2 is near a pressure rib. The bolt holes 2 and pressure ribs are obtained by stamping the machined holes on the part to be stamped using an upper die pressure rib insert 320 and a corresponding lower die pressure rib insert 120. The number of bolt holes 2 is the same as the number of lower die pressure rib inserts 120. Furthermore, for different models of chassis 1, the positions of the bolt holes 2, the positions of the pressure ribs, and the shapes of the pressure ribs are different. By changing the upper die pressure rib insert 320 and the lower die pressure rib insert 120, stamping different models of chassis 1 can be completed. For example, as... Figure 18 As shown, there are three bolt holes 2, and there are also three upper mold pressing rib inserts 320 installed on the upper main body 310 and three lower mold pressing rib inserts 120 installed on the lower main body 110.

[0073] In some embodiments, the positioning component 20 includes a positioning plate 220 and a lower elastic member 230; the positioning plate 220 is shaped to fit the part to be stamped; one end of the lower elastic member 230 is connected to the lower main body 110 and the other end is connected to the positioning plate 220; wherein, the positioning hole 210 is provided on the positioning plate 220.

[0074] The positioning plate 220, by matching the shape of the part to be stamped, plays a positioning role, allowing the part to be stamped to be quickly positioned and placed, ensuring that the machining holes on the part to be stamped are aligned with the upper die rib insert 320 and the lower die rib insert 120, thereby ensuring the accuracy of the stamping position; in addition, the positioning plate 220 can be replaced according to different models of the part to be stamped, so that the positioning plate 220 can be adapted to different models of the part to be stamped, achieving compatibility of multiple machine products. During stamping, the upper main body 310 drives the upper die rib insert 320 to move downward, cooperating with the lower die rib insert 120 and applying pressure. Under the action of pressure, the workpiece to be stamped on the positioning plate 220 is stamped, and at the same time, the positioning plate 220 moves downward, and the lower elastic member 230 is compressed to store elastic force. After stamping is completed, the upper main body 310 drives the upper die rib insert 320 to move upward, away from the lower die rib insert 120. The positioning plate 220 moves upward under the action of elastic force, and the workpiece to be stamped moves with the positioning plate 220, thereby realizing stripping.

[0075] It should be noted that the lower elastic element 230 includes, but is not limited to, a spring; in addition, the number of lower spring elements can be multiple.

[0076] It should also be noted that, for different models of parts to be stamped, corresponding positioning plates 220 are machined, and positioning holes 210 corresponding to the machining holes are opened on the positioning plates 220, thereby ensuring that the positioning plates 220 can adapt to different models of parts to be stamped and fit the corresponding shape of the parts to be stamped; that is, the number and position of the positioning holes 210 are determined by the number and position of the machining holes of the corresponding parts to be stamped; for example, Figure 18 As shown, the part to be stamped has three machining holes arranged at equal intervals around the same center in the circumferential direction. The positioning plate 220 also has three positioning holes 210 arranged at equal intervals around the same center in the circumferential direction. The three positioning holes 210 correspond one-to-one with the three machining holes.

[0077] Example 3

[0078] like Figures 1-3As shown, the mold structure includes a lower mold assembly 10, a positioning assembly 20, and an upper mold assembly 30. The lower mold assembly 10 includes a lower main body 110 and a lower mold rib insert 120, which is detachably disposed on the lower main body 110. The positioning assembly 20 is movably disposed on the lower mold assembly 10 and is configured to position the workpiece to be stamped and move relative to the lower mold assembly 10 in the height direction. The upper mold assembly 30 includes an upper main body 310 and an upper mold rib insert 320, which is detachably disposed on the upper main body 310 and is configured to move in the height direction so that the upper mold rib insert 320 and the corresponding lower mold rib insert 120 stamp the workpiece to be stamped. The positioning assembly 20 is provided with positioning holes 210, which correspond one-to-one with the lower mold rib inserts 120, so that the corresponding lower mold rib inserts 120 can pass through.

[0079] As can be seen from the above, by detachably setting the lower mold rib insert 120 to the lower main body 110 and the upper mold rib insert 320 to the upper main body 310, users can quickly replace the rib inserts according to the product model to adapt to different processing requirements without replacing the entire mold. Compared with traditional molds that are designed for a single model, this utility model allows for the replacement of the upper mold rib insert 320 and the lower mold rib insert 120 according to the product model, thereby adjusting the position and shape of the mold core and realizing the reuse of the mold. This not only improves the versatility and utilization rate of the mold, but also reduces production costs, increases production efficiency, and achieves compatibility with multiple product models. By setting a positioning component 20 that can move along the height direction relative to the lower die assembly 10, not only can the part to be stamped be placed, but it can also play a stripping role to ensure smooth demolding. In addition, the positioning component 20 plays a positioning role for the part to be stamped, and the movable connection between the positioning component 20 and the lower die assembly 10 allows the user to quickly replace the positioning component 20 according to the product model to adapt to different processing requirements. It ensures that the positioning hole 210 corresponds one-to-one with the lower die pressure rib insert 120, so that the positioning component 20 can adapt to different die core positions, thereby improving the flexibility of the positioning component 20 and the versatility of the mold.

[0080] It should be noted that, as Figure 1 As shown, the height direction is parallel to the Z direction; the upper mold rib insert 320 and the lower mold rib insert 120 correspond one-to-one.

[0081] It should also be noted that the part to be stamped is the chassis 1 of an air conditioning compressor. The chassis 1 has multiple bolt holes 2, which are evenly spaced around the same center point, and each bolt hole 2 is near a pressure rib. The bolt holes 2 and pressure ribs are obtained by stamping the machined holes on the part to be stamped using an upper die pressure rib insert 320 and a corresponding lower die pressure rib insert 120. The number of bolt holes 2 is the same as the number of lower die pressure rib inserts 120. Furthermore, for different models of chassis 1, the positions of the bolt holes 2, the positions of the pressure ribs, and the shapes of the pressure ribs are different. By changing the upper die pressure rib insert 320 and the lower die pressure rib insert 120, stamping different models of chassis 1 can be completed. For example, as... Figure 18 As shown, there are three bolt holes 2, and there are also three upper mold pressing rib inserts 320 installed on the upper main body 310 and three lower mold pressing rib inserts 120 installed on the lower main body 110.

[0082] In some embodiments, the positioning component 20 includes a positioning plate 220 and a lower elastic member 230; the positioning plate 220 is shaped to fit the part to be stamped; one end of the lower elastic member 230 is connected to the lower main body 110 and the other end is connected to the positioning plate 220; wherein, the positioning hole 210 is provided on the positioning plate 220.

[0083] The positioning plate 220, by matching the shape of the part to be stamped, plays a positioning role, allowing the part to be stamped to be quickly positioned and placed, ensuring that the machining holes on the part to be stamped are aligned with the upper die rib insert 320 and the lower die rib insert 120, thereby ensuring the accuracy of the stamping position; in addition, the positioning plate 220 can be replaced according to different models of the part to be stamped, so that the positioning plate 220 can be adapted to different models of the part to be stamped, achieving compatibility of multiple machine products. During stamping, the upper main body 310 drives the upper die rib insert 320 to move downward, cooperating with the lower die rib insert 120 and applying pressure. Under the action of pressure, the workpiece to be stamped on the positioning plate 220 is stamped, and at the same time, the positioning plate 220 moves downward, and the lower elastic member 230 is compressed to store elastic force. After stamping is completed, the upper main body 310 drives the upper die rib insert 320 to move upward, away from the lower die rib insert 120. The positioning plate 220 moves upward under the action of elastic force, and the workpiece to be stamped moves with the positioning plate 220, thereby realizing stripping.

[0084] It should be noted that the lower elastic element 230 includes, but is not limited to, a spring; in addition, the number of lower spring elements can be multiple.

[0085] It should also be noted that, for different models of parts to be stamped, corresponding positioning plates 220 are machined, and positioning holes 210 corresponding to the machining holes are opened on the positioning plates 220, thereby ensuring that the positioning plates 220 can adapt to different models of parts to be stamped and fit the corresponding shape of the parts to be stamped; that is, the number and position of the positioning holes 210 are determined by the number and position of the machining holes of the corresponding parts to be stamped; for example, Figure 18 As shown, the part to be stamped has three machining holes arranged at equal intervals around the same center in the circumferential direction. The positioning plate 220 also has three positioning holes 210 arranged at equal intervals around the same center in the circumferential direction. The three positioning holes 210 correspond one-to-one with the three machining holes.

[0086] like Figure 1 ,like Figures 6-11 As shown, in some embodiments, a first annular groove 1201 is provided on the outer wall of the lower mold pressing rib insert 120, and the lower mold assembly 10 also includes a lower mold pressing block 130, wherein the lower mold pressing block 130 abuts against the first annular groove 1201, and the lower mold pressing block 130 is connected to the lower main body 110 by fasteners.

[0087] By setting the lower die pressure block 130 and fasteners, the lower die pressure rib insert 120 can be detachably installed on the lower die assembly 10, realizing the quick installation and replacement of the lower die pressure rib insert 120, improving the replacement speed and production efficiency; when it is necessary to stamp different models of products, it is only necessary to disassemble and install the lower die pressure block 130 and fasteners to replace the lower die pressure rib insert 120 at the corresponding position.

[0088] It should be noted that the fasteners include, but are not limited to, screws. In addition, there can be multiple lower die pressing blocks 130, which are arranged at equal intervals around the first annular groove 1201 in the circumferential direction; the lower body part 110 is also provided with multiple threaded holes, which correspond one-to-one with the multiple lower die pressing blocks 130, and the threaded holes are threadedly connected to the fasteners.

[0089] like Figure 1 ,like Figures 12-17 As shown, in some embodiments, a second annular groove 3201 is provided on the outer wall of the upper mold rib insert 320, and the upper mold assembly 30 also includes an upper mold pressing block 330, wherein the upper mold pressing block 330 abuts against the second annular groove 3201, and the upper mold pressing block 330 is connected to the lower main body 110 by fasteners.

[0090] By setting the upper die pressure block 330 and fasteners, the upper die pressure rib insert 320 can be detachably installed on the upper die assembly 30, realizing the quick installation and replacement of the upper die pressure rib insert 320, improving the replacement speed and production efficiency; when it is necessary to stamp different models of products, it is only necessary to disassemble and install the upper die pressure block 330 and fasteners to replace the upper die pressure rib insert 320 at the corresponding position.

[0091] It should be noted that there can be multiple upper mold pressure blocks 330, and multiple upper mold pressure blocks 330 are arranged at equal intervals around the second annular groove 3201 in the circumferential direction; multiple upper threaded holes are provided on the upper main body 310, and the multiple upper threaded holes correspond one-to-one with the multiple upper mold pressure blocks 330, and the upper threaded holes are threadedly connected to the fasteners.

[0092] Example 4

[0093] like Figures 1-3 As shown, the mold structure includes a lower mold assembly 10, a positioning assembly 20, and an upper mold assembly 30. The lower mold assembly 10 includes a lower main body 110 and a lower mold rib insert 120, which is detachably disposed on the lower main body 110. The positioning assembly 20 is movably disposed on the lower mold assembly 10 and is configured to position the workpiece to be stamped and move relative to the lower mold assembly 10 in the height direction. The upper mold assembly 30 includes an upper main body 310 and an upper mold rib insert 320, which is detachably disposed on the upper main body 310 and is configured to move in the height direction so that the upper mold rib insert 320 and the corresponding lower mold rib insert 120 stamp the workpiece to be stamped. The positioning assembly 20 is provided with positioning holes 210, which correspond one-to-one with the lower mold rib inserts 120, so that the corresponding lower mold rib inserts 120 can pass through.

[0094] As can be seen from the above, by detachably setting the lower mold rib insert 120 to the lower main body 110 and the upper mold rib insert 320 to the upper main body 310, users can quickly replace the rib inserts according to the product model to adapt to different processing requirements without replacing the entire mold. Compared with traditional molds that are designed for a single model, this utility model allows for the replacement of the upper mold rib insert 320 and the lower mold rib insert 120 according to the product model, thereby adjusting the position and shape of the mold core and realizing the reuse of the mold. This not only improves the versatility and utilization rate of the mold, but also reduces production costs, increases production efficiency, and achieves compatibility with multiple product models. By setting a positioning component 20 that can move along the height direction relative to the lower die assembly 10, not only can the part to be stamped be placed, but it can also play a stripping role, ensuring smooth demolding. In addition, the positioning component 20 plays a positioning role for the part to be stamped, and the movable connection between the positioning component 20 and the lower die assembly 10 allows the user to quickly replace the positioning component 20 according to the product model to adapt to different processing requirements, ensuring that the positioning hole 210 corresponds one-to-one with the lower die pressure rib insert 120, thereby improving the flexibility of the positioning component 20 and the versatility of the mold.

[0095] It should be noted that, as Figure 1 As shown, the height direction is parallel to the Z direction; the upper mold rib insert 320 and the lower mold rib insert 120 correspond one-to-one.

[0096] It should also be noted that the part to be stamped is the chassis 1 of an air conditioning compressor. The chassis 1 has multiple bolt holes 2, which are evenly spaced around the same center point, and each bolt hole 2 is near a pressure rib. The bolt holes 2 and pressure ribs are obtained by stamping the machined holes on the part to be stamped using an upper die pressure rib insert 320 and a corresponding lower die pressure rib insert 120. The number of bolt holes 2 is the same as the number of lower die pressure rib inserts 120. Furthermore, for different models of chassis 1, the positions of the bolt holes 2, the positions of the pressure ribs, and the shapes of the pressure ribs are different. By changing the upper die pressure rib insert 320 and the lower die pressure rib insert 120, stamping different models of chassis 1 can be completed. For example, as... Figure 18 As shown, there are three bolt holes 2, and there are also three upper mold pressing rib inserts 320 installed on the upper main body 310 and three lower mold pressing rib inserts 120 installed on the lower main body 110.

[0097] In some embodiments, the positioning component 20 includes a positioning plate 220 and a lower elastic member 230; the positioning plate 220 is shaped to fit the part to be stamped; one end of the lower elastic member 230 is connected to the lower main body 110 and the other end is connected to the positioning plate 220; wherein, the positioning hole 210 is provided on the positioning plate 220.

[0098] The positioning plate 220, by matching the shape of the part to be stamped, plays a positioning role, allowing the part to be stamped to be quickly positioned and placed, ensuring that the machining holes on the part to be stamped are aligned with the upper die rib insert 320 and the lower die rib insert 120, thereby ensuring the accuracy of the stamping position; in addition, the positioning plate 220 can be replaced according to different models of the part to be stamped, so that the positioning plate 220 can be adapted to different models of the part to be stamped, achieving compatibility of multiple machine products. During stamping, the upper main body 310 drives the upper die rib insert 320 to move downward, cooperating with the lower die rib insert 120 and applying pressure. Under the action of pressure, the workpiece to be stamped on the positioning plate 220 is stamped, and at the same time, the positioning plate 220 moves downward, and the lower elastic member 230 is compressed to store elastic force. After stamping is completed, the upper main body 310 drives the upper die rib insert 320 to move upward, away from the lower die rib insert 120. The positioning plate 220 moves upward under the action of elastic force, and the workpiece to be stamped moves with the positioning plate 220, thereby realizing stripping.

[0099] It should be noted that the lower elastic element 230 includes, but is not limited to, a spring; in addition, the number of lower spring elements can be multiple.

[0100] It should also be noted that, for different models of parts to be stamped, corresponding positioning plates 220 are machined, and positioning holes 210 corresponding to the machining holes are opened on the positioning plates 220, thereby ensuring that the positioning plates 220 can adapt to different models of parts to be stamped and fit the corresponding shape of the parts to be stamped; that is, the number and position of the positioning holes 210 are determined by the number and position of the machining holes of the corresponding parts to be stamped; for example, Figure 18 As shown, the part to be stamped has three machining holes arranged at equal intervals around the same center in the circumferential direction. The positioning plate 220 also has three positioning holes 210 arranged at equal intervals around the same center in the circumferential direction. The three positioning holes 210 correspond one-to-one with the three machining holes.

[0101] like Figure 1 ,like Figures 6-11 As shown, in some embodiments, a first annular groove 1201 is provided on the outer wall of the lower mold pressing rib insert 120, and the lower mold assembly 10 also includes a lower mold pressing block 130, wherein the lower mold pressing block 130 abuts against the first annular groove 1201, and the lower mold pressing block 130 is connected to the lower main body 110 by fasteners.

[0102] By setting the lower die pressure block 130 and fasteners, the lower die pressure rib insert 120 can be detachably installed on the lower die assembly 10, realizing the quick installation and replacement of the lower die pressure rib insert 120, improving the replacement speed and production efficiency; when it is necessary to stamp different models of products, it is only necessary to disassemble and install the lower die pressure block 130 and fasteners to replace the lower die pressure rib insert 120 at the corresponding position.

[0103] It should be noted that the fasteners include, but are not limited to, screws. In addition, there can be multiple lower die pressing blocks 130, which are arranged at equal intervals around the first annular groove 1201 in the circumferential direction; the lower body part 110 is also provided with multiple threaded holes, which correspond one-to-one with the multiple lower die pressing blocks 130, and the threaded holes are threadedly connected to the fasteners.

[0104] like Figure 1 ,like Figures 12-17 As shown, in some embodiments, a second annular groove 3201 is provided on the outer wall of the upper mold rib insert 320, and the upper mold assembly 30 also includes an upper mold pressing block 330, wherein the upper mold pressing block 330 abuts against the second annular groove 3201, and the upper mold pressing block 330 is connected to the lower main body 110 by fasteners.

[0105] By setting the upper die pressure block 330 and fasteners, the upper die pressure rib insert 320 can be detachably installed on the upper die assembly 30, realizing the quick installation and replacement of the upper die pressure rib insert 320, improving the replacement speed and production efficiency; when it is necessary to stamp different models of products, it is only necessary to disassemble and install the upper die pressure block 330 and fasteners to replace the upper die pressure rib insert 320 at the corresponding position.

[0106] It should be noted that there can be multiple upper mold pressure blocks 330, and multiple upper mold pressure blocks 330 are arranged at equal intervals around the second annular groove 3201 in the circumferential direction; multiple upper threaded holes are provided on the upper main body 310, and the multiple upper threaded holes correspond one-to-one with the multiple upper mold pressure blocks 330, and the upper threaded holes are threadedly connected to the fasteners.

[0107] like Figure 4 As shown, in some embodiments, the lower main body 110 is provided with a plurality of lower mounting holes, and the lower die pressing rib insert 120 is disposed in the lower mounting holes; the upper main body 310 is provided with a plurality of upper mounting holes, and the upper die pressing rib insert 320 is disposed in the upper mounting holes; wherein, the lower die pressing rib insert 120 and the upper die pressing rib insert 320 correspond one-to-one with the processing hole positions of the workpiece to be stamped.

[0108] By providing multiple mounting holes for the lower mold rib insert 120, the lower mold rib insert 120 can be installed by selecting the corresponding lower mounting hole according to the position of the machined hole, thus eliminating the need to replace the mold and further improving the versatility of the mold structure and production efficiency. Similarly, by providing multiple mounting holes for the upper mold rib insert 320, the upper mold rib insert 320 can be installed by selecting the corresponding upper mounting hole according to the position of the machined hole, thus eliminating the need to replace the mold and further improving the versatility of the mold structure and production efficiency.

[0109] It should be noted that, taking into account the machining hole positions of different models of workpieces to be processed, upper mounting holes and lower mounting holes can be respectively set at corresponding positions on the upper main body 310 and lower main body 110, thereby ensuring that the installation positions of the upper die rib insert 320 and the lower die rib insert 120 correspond to the machining hole positions; in addition, the number of upper mounting holes can be greater than the number of upper die rib inserts 320, and the number of lower mounting holes can be greater than the number of lower die rib inserts 120, which are determined according to the position layout of the machining hole positions of different models of workpieces to be stamped, as well as the number of machining hole positions on each workpiece to be stamped;

[0110] For example, the layout of the machining holes of different models of stamping parts is that six machining holes are arranged at equal intervals around the same center. Therefore, six upper mounting holes are provided on the upper main body 310 at equal intervals around the same center, and six lower mounting holes are provided on the lower main body 110 at equal intervals around the same center.

[0111] For example, the combined layout of machining holes for different types of stamped parts is such that three machining holes P are arranged circumferentially at equal intervals around the same center O, with a distance R1 between machining hole P and center O; another three machining holes Q are arranged circumferentially at equal intervals around the same center O, with a distance R2 between machining hole Q and center O, where R1 is less than R2; and the three machining holes P and three machining holes Q are staggered. Therefore, if... Figure 5 As shown, the upper body 310 is provided with first upper mounting holes 3101 corresponding to three machining hole positions P and second upper mounting holes 3107 corresponding to three machining hole positions Q, respectively. Figure 4 As shown, a first lower mounting hole 1101 corresponding to each of the three machining hole positions P and a second lower mounting hole 1106 corresponding to each of the three machining hole positions Q are provided on the lower main body 110.

[0112] For example, when the part to be stamped is the chassis 1 of an air conditioning compressor, R1 is 75mm and R2 is 88mm; Figure 18 As shown, the chassis 1 has three machining holes P. According to the position of the machining holes P on the chassis 1, the corresponding three first upper mounting holes 3101 are selected to install the upper molded rib insert 320, and the three first lower mounting holes 1101 are selected to install the lower molded rib insert 120.

[0113] like Figure 1 , Figures 6-11As shown, in some embodiments, the lower die pressing rib insert 120 includes a lower die pressing rib inlet 1202 and a lower die cutting edge inlet 1203; the lower die pressing rib inlet 1202 is disposed in the lower mounting hole, and the first annular groove 1201 is disposed on the outer wall of the lower die pressing rib inlet; the lower die cutting edge inlet 1203 is disposed in the lower die pressing rib inlet 1202; wherein, the top of the lower die pressing rib inlet is provided with a pressing rib boss 1205, and the pressing rib boss 1205 surrounds the lower die cutting edge inlet 1203.

[0114] like Figure 1 , Figures 12-17 As shown, in some embodiments, the upper die pressing rib insert 320 includes an upper die pressing rib insert 3202 and an upper die punch 3203; the upper die pressing rib insert 3202 is disposed in the upper mounting hole, and the second annular groove 3201 is disposed on the outer wall of the upper die pressing rib insert; the upper die punch 3203 is movably disposed in the upper die pressing rib insert 3202; wherein, the bottom of the upper die pressing rib insert is provided with a pressing rib groove 3205, the pressing rib groove 3205 surrounds the upper die punch 3203, the pressing rib groove 3205 cooperates with the pressing rib boss 1205 to press the part to be pressed; the upper die punch 3203 cooperates with the lower die cutting edge insert 1203 to punch holes in the part to be pressed.

[0115] The pressing groove 3205 and the pressing boss 1205 cooperate to press the part to be stamped. The upper die punch 3203 and the lower die cutter insert 1203 cooperate to punch the part to be stamped, so that the pressing and punching of the product can be carried out simultaneously, further improving production efficiency.

[0116] It should be noted that the upper die punch 3203 and the lower die cutting edge insert 1203 work together to punch a round hole.

[0117] It should also be noted that, such as Figure 1 As shown, the upper die pressing rib insert 3202 is provided with a punch hole, and the upper main body 310 is provided with a through hole. The through hole and the punch hole are connected to form a fixing hole. The upper die punch 3203 is located in the fixing hole. The upper die punch 3203 is connected to the upper die base 3102 through a set screw, which facilitates the quick replacement of the upper die punch 3203.

[0118] Example 5

[0119] like Figures 1-3As shown, the mold structure includes a lower mold assembly 10, a positioning assembly 20, and an upper mold assembly 30. The lower mold assembly 10 includes a lower main body 110 and a lower mold rib insert 120, which is detachably disposed on the lower main body 110. The positioning assembly 20 is movably disposed on the lower mold assembly 10 and is configured to position the workpiece to be stamped and move relative to the lower mold assembly 10 in the height direction. The upper mold assembly 30 includes an upper main body 310 and an upper mold rib insert 320, which is detachably disposed on the upper main body 310 and is configured to move in the height direction so that the upper mold rib insert 320 and the corresponding lower mold rib insert 120 stamp the workpiece to be stamped. The positioning assembly 20 is provided with positioning holes 210, which correspond one-to-one with the lower mold rib inserts 120, so that the corresponding lower mold rib inserts 120 can pass through.

[0120] As can be seen from the above, by detachably setting the lower mold rib insert 120 to the lower main body 110 and the upper mold rib insert 320 to the upper main body 310, users can quickly replace the rib inserts according to the product model to adapt to different processing requirements without replacing the entire mold. Compared with traditional molds that are designed for a single model, this utility model allows for the replacement of the upper mold rib insert 320 and the lower mold rib insert 120 according to the product model, thereby adjusting the position and shape of the mold core and realizing the reuse of the mold. This not only improves the versatility and utilization rate of the mold, but also reduces production costs, increases production efficiency, and achieves compatibility with multiple product models. By setting a positioning component 20 that can move along the height direction relative to the lower die assembly 10, not only can the part to be stamped be placed, but it can also play a stripping role to ensure smooth demolding. In addition, the positioning component 20 plays a positioning role for the part to be stamped, and the movable connection between the positioning component 20 and the lower die assembly 10 allows the user to quickly replace the positioning component 20 according to the product model to adapt to different processing requirements. It ensures that the positioning hole 210 corresponds one-to-one with the lower die pressure rib insert 120, so that the positioning component 20 can adapt to different die core positions, thereby improving the flexibility of the positioning component 20 and the versatility of the mold.

[0121] It should be noted that, as Figure 1 As shown, the height direction is parallel to the Z direction.

[0122] It should also be noted that the part to be stamped is the chassis 1 of an air conditioning compressor. The chassis 1 has multiple bolt holes 2, which are evenly spaced around the same center point, and each bolt hole 2 is near a pressure rib. The bolt holes 2 and pressure ribs are obtained by stamping the machined holes on the part to be stamped using an upper die pressure rib insert 320 and a corresponding lower die pressure rib insert 120. The number of bolt holes 2 is the same as the number of lower die pressure rib inserts 120. Furthermore, for different models of chassis 1, the positions of the bolt holes 2, the positions of the pressure ribs, and the shapes of the pressure ribs are different. By changing the upper die pressure rib insert 320 and the lower die pressure rib insert 120, stamping different models of chassis 1 can be completed. For example, as... Figure 18 As shown, there are three bolt holes 2, and there are also three upper mold pressing rib inserts 320 installed on the upper main body 310 and three lower mold pressing rib inserts 120 installed on the lower main body 110.

[0123] In some embodiments, the positioning component 20 includes a positioning plate 220 and a lower elastic member 230; the positioning plate 220 is shaped to fit the part to be stamped; one end of the lower elastic member 230 is connected to the lower main body 110 and the other end is connected to the positioning plate 220; wherein, the positioning hole 210 is provided on the positioning plate 220.

[0124] The positioning plate 220, by matching the shape of the part to be stamped, plays a positioning role, allowing the part to be stamped to be quickly positioned and placed, ensuring that the machining holes on the part to be stamped are aligned with the upper die rib insert 320 and the lower die rib insert 120, thereby ensuring the accuracy of the stamping position; in addition, the positioning plate 220 can be replaced according to different models of the part to be stamped, so that the positioning plate 220 can be adapted to different models of the part to be stamped, achieving compatibility of multiple machine products. During stamping, the upper main body 310 drives the upper die rib insert 320 to move downward, cooperating with the lower die rib insert 120 and applying pressure. Under the action of pressure, the workpiece to be stamped on the positioning plate 220 is stamped, and at the same time, the positioning plate 220 moves downward, and the lower elastic member 230 is compressed to store elastic force. After stamping is completed, the upper main body 310 drives the upper die rib insert 320 to move upward, away from the lower die rib insert 120. The positioning plate 220 moves upward under the action of elastic force, and the workpiece to be stamped moves with the positioning plate 220, thereby realizing stripping.

[0125] It should be noted that the lower elastic element 230 includes, but is not limited to, a spring; in addition, the number of lower spring elements can be multiple.

[0126] It should also be noted that, for different models of parts to be stamped, corresponding positioning plates 220 are machined, and positioning holes 210 corresponding to the machining holes are opened on the positioning plates 220, thereby ensuring that the positioning plates 220 can adapt to different models of parts to be stamped and fit the corresponding shape of the parts to be stamped; that is, the number and position of the positioning holes 210 are determined by the number and position of the machining holes of the corresponding parts to be stamped; for example, Figure 18 As shown, the part to be stamped has three machining holes arranged at equal intervals around the same center in the circumferential direction. The positioning plate 220 also has three positioning holes 210 arranged at equal intervals around the same center in the circumferential direction. The three positioning holes 210 correspond one-to-one with the three machining holes.

[0127] like Figure 1 ,like Figures 6-11 As shown, in some embodiments, a first annular groove 1201 is provided on the outer wall of the lower mold pressing rib insert 120, and the lower mold assembly 10 also includes a lower mold pressing block 130, wherein the lower mold pressing block 130 abuts against the first annular groove 1201, and the lower mold pressing block 130 is connected to the lower main body 110 by fasteners.

[0129] It should be noted that the fasteners include, but are not limited to, screws. In addition, there can be multiple lower die pressing blocks 130, which are arranged at equal intervals around the first annular groove 1201 in the circumferential direction; the lower body part 110 is also provided with multiple threaded holes, which correspond one-to-one with the multiple lower die pressing blocks 130, and the threaded holes are threadedly connected to the fasteners.

[0134] By providing multiple mounting holes for the lower mold rib insert 120, the lower mold rib insert 120 can be installed by selecting the corresponding lower mounting hole according to the position of the machined hole, thus eliminating the need to replace the mold and further improving the versatility of the mold structure and production efficiency. Similarly, by providing multiple mounting holes for the upper mold rib insert 320, the upper mold rib insert 320 can be installed by selecting the corresponding upper mounting hole according to the position of the machined hole, thus eliminating the need to replace the mold and further improving the versatility of the mold structure and production efficiency.

[0135] It should be noted that, taking into account the machining hole positions of different models of workpieces to be processed, upper mounting holes and lower mounting holes can be respectively set at corresponding positions on the upper main body 310 and lower main body 110, thereby ensuring that the installation positions of the upper die rib insert 320 and the lower die rib insert 120 correspond to the machining hole positions; in addition, the number of upper mounting holes can be greater than the number of upper die rib inserts 320, and the number of lower mounting holes can be greater than the number of lower die rib inserts 120, which are determined according to the position layout of the machining hole positions of different models of workpieces to be stamped, as well as the number of machining hole positions on each workpiece to be stamped;

[0136] For example, the layout of the machining holes of different models of stamping parts is that six machining holes are arranged at equal intervals around the same center. Therefore, six upper mounting holes are provided on the upper main body 310 at equal intervals around the same center, and six lower mounting holes are provided on the lower main body 110 at equal intervals around the same center.

[0137] For example, the combined layout of machining holes for different types of stamped parts is such that three machining holes P are arranged circumferentially at equal intervals around the same center O, with a distance R1 between machining hole P and center O; another three machining holes Q are arranged circumferentially at equal intervals around the same center O, with a distance R2 between machining hole Q and center O, where R1 is less than R2; and the three machining holes P and three machining holes Q are staggered. Therefore, if... Figure 5 As shown, the upper body 310 is provided with first upper mounting holes 3101 corresponding to three machining hole positions P and second upper mounting holes 3107 corresponding to three machining hole positions Q, respectively. Figure 4 As shown, a first lower mounting hole 1101 corresponding to each of the three machining hole positions P and a second lower mounting hole 1106 corresponding to each of the three machining hole positions Q are provided on the lower main body 110.

According to the position of the machining holes P on the chassis 1, the corresponding three first upper mounting holes 3101 are selected to install the upper molded rib insert 320, and the three first lower mounting holes 1101 are selected to install the lower molded rib insert 120.
