Description

Technical Field

[0001] This utility model relates to the field of multi-station mold technology, specifically a multi-station quick-switching mold structure. Background Technology

[0002] Stamping is a pressure processing method that uses a stamping die mounted on a press to apply pressure to a material at room temperature, causing it to separate or undergo plastic deformation, thereby obtaining the desired workpiece. A stamping die is a special piece of equipment used in cold stamping to process materials into parts.

[0003] General stamping dies are suitable for rapid and large-volume production of one type of workpiece. However, for the production of small batches of stamped workpieces, due to the limitations of space and the number of stamping machines, it is necessary to disassemble the current stamping die after completing the stamping production of one type of workpiece and then replace it with a stamping die for the next type of workpiece. Since traditional dies have the problems of single workstation and inconvenient switching, frequent stopping of stamping operations to disassemble and assemble dies will greatly reduce the production efficiency of stamped workpieces.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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] Please see Figures 1-3 This utility model discloses a multi-station quick-change mold structure, including a support frame 1 and a rotating shaft 2 movably mounted on the support frame 1. Multiple upper molds 4 are mounted on the rotating shaft 2 via a first connecting member 3, and lower molds 5 corresponding to the upper molds 4 are also mounted on the rotating shaft 2 via a second connecting member. The support frame 1 is also provided with a driving component for moving the upper molds 4 downwards, and a support component for supporting the lower molds 5.

[0021] Specifically, a drive motor 6 is fixedly connected to the support frame 1, a drive gear 7 is fixedly sleeved on the output shaft of the drive motor 6, and a driven gear 8 is fixedly sleeved on the rotating shaft 2, with the drive gear 7 meshing with the driven gear 8.

[0022] In this embodiment, the rotation of the rotating shaft 2 can be achieved by the driving gear 7 and the driven gear 8, thereby enabling the switching of different combinations of upper die 4 and lower die 5 to the work station and realizing different modes of stamping.

[0023] Specifically, the first connecting member is fixedly sleeved on the surface of the rotating shaft 2, and the first connecting member 3 is fixedly connected to the first extension member 20 by connecting screws. The first extension member 20 is movably connected to the fixing member 9, and the fixing member 9 can move up and down relative to the first extension member 20. The fixing member 9 is fixedly connected to the upper mold 4.

[0024] In this embodiment, the first extension 20 can be disassembled by removing the connecting screws, so that different combinations of upper mold 4 and lower mold 5 can be replaced as needed.

[0025] Specifically, a guide rod 10 is fixedly connected to the surface of the first extension member 20, the fixing member 9 is movably sleeved on the surface of the guide rod 10, a return spring 11 is sleeved on the surface of the guide rod 10, one end of the return spring 11 is connected to the fixing member 9, and the other end of the return spring 11 is connected to the first extension member 20.

[0026] In this embodiment, during the downward movement of the upper mold 4, the guide rod 10 can play a guiding and limiting role, while the reset spring 11 can automatically reset the upper mold 4 upward when the drive cylinder 12 retracts.

[0027] Specifically, the driving component includes a driving cylinder 12, and a connector 13 is fixedly connected to the output shaft of the driving cylinder 12. A connector groove 14 is provided on the top of the fixing component 9.

[0028] In this embodiment, the fastener 9 can be limited by the connector 13 and the connector slot 14, thereby preventing the rotating shaft 2 from rotating and preventing deviation during stamping.

[0029] Specifically, the second connector 15 is fixedly sleeved on the surface of the rotating shaft 2, and the surface of the second connector 15 is connected to the second extension 16 by fastening screws. The second extension is fixedly connected to the lower mold 5.

[0030] In this embodiment, similarly, different combinations of upper mold 4 and lower mold 5 can be replaced by removing the fastening screws.

[0031] Specifically, the support component includes a support platform 17 and an electric push rod 18. The output shaft of the electric push rod 18 is fixedly connected to the support platform 17. The bottom of the lower mold 5 is provided with a groove 19, and the size of the support platform 17 is adapted to the size of the groove 19.

[0032] In this embodiment, the support platform 17 can limit the lower mold 5 through the groove 19 to prevent movement, and at the same time, it can also support the lower mold 5 to prevent the second extension 16 from deforming when the upper mold 4 is squeezed.

[0033] The working principle and usage process of this utility model are as follows: When in use, select the combination of upper mold 4 and lower mold 5 as needed, control the drive motor 6 to rotate, thereby causing the rotating shaft 2 to rotate through the drive gear 7 and driven gear 8, so that the upper mold 4 and lower mold 5 move to the central axis position of the drive cylinder 12 and the support platform 17.

[0034] Then, the drive motor 6 brakes, and the output shaft of the drive cylinder 12 drives the connector 13 to move downward, engaging with the connector slot 14 on the top of the fixing part 9, further achieving braking and limiting. At the same time, the output shaft of the electric push rod 18 moves the support platform 17 upward, causing the support platform 17 to insert into the groove 19, achieving support and limiting for the lower die 5. Then, the object to be stamped is placed on the lower die 5, and the output shaft of the drive cylinder 12 compresses the fixing part 9 through the connector 13, causing the return spring 11 to deform, the upper die 4 compresses the object, and the corresponding lower die 5 achieves stamping.

[0035] In summary, this multi-station quick-change mold structure uses a drive motor 6 and gear transmission to rotate the rotating shaft 2, enabling rapid switching between different combinations of upper mold 4 and lower mold 5 for stamping. The detachable first connecting piece 3, connecting screws, second connecting piece 15, and fastening screws facilitate mold combination replacement, solving the problems of single-station operation and inconvenient switching in traditional molds, thus improving mold usage flexibility. The guide rod 10 and return spring 11 ensure stable movement and automatic reset of the upper mold 4; the plug-in piece 13 and plug-in slot 14 and groove 19 structure provide precise positioning to prevent stamping deviation; the support component composed of the support platform 17 and electric push rod 18 prevents mold deformation, ensuring stamping accuracy and mold lifespan.
