Description

Technical Field

[0001] This utility model relates to the field of mold technology, and more specifically, to a cold stamping mold. Background Technology

[0002] In the production of heat dissipation holes for most stamped products, as customers demand an increasing number of heat dissipation holes, in order to avoid insufficient punching strength of the mold due to the close spacing of the heat dissipation holes, several processes are opened for processing the same heat dissipation hole position during the front-end mold design.

[0003] During the stamping process of heat dissipation holes in sheet metal, cold stamping dies are difficult to adapt to the actual use situation. The upper die needs to be changed constantly, and it is difficult to switch different stamping areas with a single die to achieve stamping processing. This results in poor adjustability and poor applicability of the die stamping process. Utility Model Content

[0004] To overcome the aforementioned deficiencies of the prior art, this utility model provides the following technical solution: a cold stamping die, comprising a main die, multiple main punches, and a support plate. The multiple main punches are fixed to the lower surface of the main die, and the support plate is fixed to the upper surface of the main die. Switching components are provided on both sides of the main die. Each switching component includes a support frame disposed on one side of the main die, which is fixedly connected to the support plate. A linkage electric cylinder is fixedly connected inside the support frame, and a push rod is fixedly connected to the output end of the linkage electric cylinder. The switching component also includes a secondary die, multiple secondary punches, and a bottom die. The secondary die is fixed to the bottom end of the push rod, and the multiple secondary punches are fixed to the lower surface of the secondary die. The bottom die is located below the main punches.

[0005] Preferably, both auxiliary molds are slidably connected to the main mold, and the two auxiliary molds are symmetrically arranged about the main mold. The lower surface of the main mold and the lower surface of the auxiliary mold are at the same horizontal line, and the outer walls of both the main mold and the auxiliary mold are smooth surfaces.

[0006] A support plate is fixedly connected to the lower surface of the bottom mold, a reinforcing plate is fixedly installed on the lower surface of the support plate, and multiple supports are fixedly connected to the lower surface of the reinforcing plate. A pressure plate is fixedly connected to the upper surface of the support plate, and both support frames are fixedly connected to the pressure plate. Multiple pressure columns are fixedly installed on the upper surface of the pressure plate, and a stamping plate is installed at the top of each pressure column. The multiple pressure columns are fixedly connected to the stamping plate.

[0007] When using this technology, for applications requiring overall punching, the main die and two auxiliary dies are positioned on the same parallel plane. Multiple main punches on the lower surface of the main die and multiple auxiliary punches on the lower surfaces of the two auxiliary dies achieve large-area punching coverage. For medium-area punching, the linkage electric cylinder drives the push rod upwards and retracts, causing the auxiliary dies to move multiple auxiliary punches upwards. The main punches on the lower surface of the main die and the auxiliary punches on the lower surface of the left auxiliary die then perform the punching. For applications requiring minimal area punching, two linkage electric cylinders are activated, and two push rods respectively drive the two auxiliary dies upwards, with the two auxiliary dies moving upwards synchronously.

[0008] Preferably, a fixed post is fixedly connected to one side of the support frame, and a region switching component is provided at one end of the fixed post. The region switching component includes a branch electric cylinder fixedly installed at one end of the fixed post. A retraction rod is fixedly installed at the output end of the branch electric cylinder, and a branch pressure plate is fixedly installed at the bottom end of the retraction rod. Multiple branch punches are fixedly connected to the lower surface of the branch pressure plate. The branch pressure plate has a rectangular cross-sectional shape, and the branch electric cylinder is used to push the retraction rod downward.

[0009] When this technology is in use, the support frame provides support to the fixed column, the branch electric cylinder drives the retraction rod to move upward and retract, the retraction rod drives the branch pressure plate to move upward and retract, and the branch pressure plate drives multiple branch punches to move upward.

[0010] The technical effects and advantages of this utility model are as follows:

[0011] 1. This utility model adopts a switching component, which selects the main mold and two auxiliary molds to be on the same parallel plane. When a medium area punching is required, the linkage electric cylinder drives the push rod to move upward and retract. At the same time, the push rod drives the auxiliary mold to move upward. Multiple main punches on the lower surface of the main mold and multiple auxiliary punches on the lower surface of the left auxiliary mold perform punching. When the smallest area is required, the two linkage electric cylinders are activated, and the two auxiliary molds move upward synchronously. In this way, only the multiple main punches on the lower surface of the main mold are used for punching. One mold can achieve multi-area and multi-region switching, and the switching applicability is wider.

[0012] 2. This utility model adopts a fixed column to support the branch electric cylinder. The retraction rod drives the branch pressure plate to move up and retract, and the branch punch can move up and retract, reducing the stamping area and realizing stamping processing of different shapes.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] As attached Figure 1 - Appendix Figure 5 The present invention relates to a cold stamping die, which is equipped with a switching component. The switching component enables the use of multiple areas and regions in a single die, thus broadening its applicability. The specific structural configuration of the switching component is as follows.

[0021] In this embodiment, as shown in the appendix Figure 1 - Appendix Figure 2 As shown, multiple main punches 2 are fixed to the lower surface of the main mold 1, and a support plate 3 is fixed to the upper surface of the main mold 1. Switching components are provided on both sides of the main mold 1. The switching components include a support frame 4 set on one side of the main mold 1, which is fixedly connected to the support plate 3. A linkage electric cylinder 8 is fixedly connected inside the support frame 4, and a push rod 5 is fixedly connected to the output end of the linkage electric cylinder 8. The switching components also include a secondary mold 6, multiple secondary punches 7, and a bottom mold 9. The secondary mold 6 is fixed to the bottom end of the push rod 5, and the multiple secondary punches 7 are fixed to the lower surface of the secondary mold 6. The bottom mold 9 is located below the main punches 2. Both secondary molds 6 are slidably connected to the main mold 1. The two secondary molds 6 are symmetrically arranged about the main mold 1. The lower surface of the main mold 1 and the lower surface of the secondary mold 6 are at the same horizontal line, and the outer walls of the main mold 1 and the secondary mold 6 are smooth surfaces.

[0022] In this embodiment, as shown in the appendix Figure 1 - Appendix Figure 4 As shown, a support plate 10 is fixedly connected to the lower surface of the bottom mold 9, and a reinforcing plate 11 is fixedly installed on the lower surface of the support plate 10. Multiple supports 12 are fixedly connected to the lower surface of the reinforcing plate 11 so that the multiple supports 12 can support the reinforcing plate 11. The reinforcing plate 11 supports the support plate 10, increasing the stability of the support plate 10. A pressure plate 13 is fixedly connected to the upper surface of the support plate 3, and both support frames 4 are fixedly connected to the pressure plate 13. Multiple pressure columns 14 are fixedly installed on the upper surface of the pressure plate 13, and a stamping plate 15 is installed at the top of the pressure column 14.

[0023] In this embodiment, when the cold stamping die is used for overall punching, the main die 1 and the two auxiliary dies 6 are placed on the same parallel plane. This allows the multiple main punches 2 on the lower surface of the main die 1 and the multiple auxiliary punches 7 on the lower surfaces of the two auxiliary dies 6 to achieve large-area punching. When medium-area punching is required, the support frame 4 is supported by the support plate 3, and the support frame 4 supports the linkage electric cylinder 8. The linkage electric cylinder 8 drives the push rod 5 to move upward and retract. At the same time, the push rod 5 drives the auxiliary die 6 to move upward, and the auxiliary die 6 drives the multiple auxiliary punches 7 to move upward. In this way, the multiple main punches 2 on the lower surface of the main die 1 and the multiple auxiliary punches 7 on the lower surface of the left auxiliary die 6 perform stamping. When the minimum area is required, the two linkage electric cylinders 8 are activated. The two linkage electric cylinders 8 drive the two push rods 5 to move upward and retract respectively. The two push rods 5 drive the two auxiliary molds 6 to move upward respectively. The two auxiliary molds 6 move upward synchronously. In this way, only the multiple main punches 2 on the lower surface of the main mold 1 are used for stamping. This allows different stamping areas to be selected according to actual needs, realizing the multi-purpose use of the model.

[0024] During stamping, the stamping plate 15 is fixed on the stamping end of the stamping equipment. The stamping plate 15 stamps the pressure column 14, the pressure column 14 drives the pressure plate 13 to stamp, the pressure plate 13 drives the support plate 3 to make the main mold 1 stamp, the main mold 1 drives multiple main punches 2 to stamp, and multiple supports 12 support the reinforcing plate 11. The reinforcing plate 11 supports the support plate 10, the support plate 10 supports the bottom mold 9, and the bottom mold 9 can support the lower surface of the stamped part.

[0025] In this embodiment, as shown in the appendix Figure 2 - Appendix Figure 5As shown, a fixed column 16 is fixedly connected to one side of the support frame 4, and a region switching assembly is provided at one end of the fixed column 16.

Multiple branch punches 20 are fixedly connected to the lower surface of the branch pressure plate 19. The branch pressure plate 19 has a rectangular cross-sectional shape, and the branch electric cylinder 17 is used to push the retraction rod 18 downward.

[0026] When this technology is in use, the support frame 4 provides support force to the fixed column 16, the fixed column 16 supports the branch electric cylinder 17, the branch electric cylinder 17 drives the retraction rod 18 to move upward and retract, the retraction rod 18 drives the branch pressure plate 19 to move upward and retract, the branch pressure plate 19 drives multiple branch punches 20 to move upward, and the branch punches 20 can move upward and retract.
