Description

Technical Field

[0001] This invention relates to the field of stamping die technology, and in particular to an automotive stamping die with an auxiliary ejection mechanism. Background Technology

[0002] Automotive parts, as the foundation of the automotive industry, are a necessary factor supporting its continued healthy development. Stamping equipment is used in the processing of automotive parts to form them. After stamping, the parts need to be removed from the stamping die, a process known as unpacking. Existing automotive stamping dies sometimes use manual unpacking, and sometimes use springs or other methods to push the parts upwards. These methods have the following drawbacks in practical use:

[0003] 1. Manual unloading poses certain safety hazards, and the unloading process is slow, which greatly reduces the efficiency of automotive stamping.

[0004] 2. Using springs or similar methods to eject automotive parts upwards is ineffective. Repeated compression and release of the springs can cause deformation, affecting the ejection process. Furthermore, the function is limited; it can only eject parts upwards but cannot remove them from the stamping die. The parts still need to be removed manually or with other equipment, which is inconvenient. Summary of the Invention

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0009] As a preferred embodiment of the automotive stamping die with auxiliary ejection mechanism described in this invention, the rack plate is fixedly connected to the inner wall of the movable cavity, the gear disk meshes with the rack plate, the gear disk rotates in contact with the movable cavity, and the round rod slides in contact with the slide groove.

[0010] As a preferred embodiment of the automotive stamping die with auxiliary ejection mechanism described in this invention, the lifting mechanism includes a lifting seat disposed on the upper end of the lower stamping die base, and two electric telescopic rods symmetrically disposed on the lower end of the lifting seat. The electric telescopic rods are fixedly connected to the lifting seat and are embedded in the lower stamping die base.

The lifting seat is disposed between two vertical plates, and the lower end of the lifting seat is fixedly connected with a positioning plate. The positioning plate is inserted into the positioning groove, and the positioning plate is slidably connected to the positioning groove.

[0012] As a preferred embodiment of the automotive stamping die with auxiliary ejection mechanism described in this invention, the positioning mechanism includes an L-shaped insert plate disposed in a through slot, a slider disposed on the side of the L-shaped insert plate, and a positioning spring disposed on the side of the slider. The L-shaped insert plate passes through the through slot and is slidably connected to the through slot. The bent end of the L-shaped insert plate is disposed below the extrusion plate, and the lower end of the extrusion plate is configured as a slope.

[0013] As a preferred embodiment of the automotive stamping die with auxiliary ejection mechanism described in this invention, both the slider and the positioning spring are disposed in the groove, and the slider is slidably connected to the groove.

[0016] The beneficial effects of this invention are:

[0017] 1.

[0018] 2. When the lifting seat moves upward, it drives the positioning mechanism to move upward. When the L-shaped insert plate in the positioning mechanism contacts the extrusion plate, the extrusion plate pushes the L-shaped insert plate to slide along the through groove, so that one end of the L-shaped insert plate moves out of the slot. At this time, the lifting seat continues to move upward, so that the clamping plate is inserted into the clamping groove of the transmission cylinder. When the lifting seat continues to move upward, the transmission cylinder drives the gear plate to roll upward along the rack plate, so that the concave rotating frame flips upward. The concave rotating frame drives the automotive stamping part to flip upward through the docking seat, so that the flipping angle of the concave rotating frame is close to or equal to 180 degrees, thereby separating the automotive stamping part from the docking seat, and then completing the unloading and transfer of the automotive stamping part. The automotive stamping part is moved out of the stamping die base and then flipped and transferred away from the top of the stamping die base. The whole process is completed automatically, with a high degree of automation and high efficiency, which greatly improves the stamping efficiency of automotive parts. Attached Figure Description

[0027] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figures 1 to 6This invention provides a technical solution: an automotive stamping die with an auxiliary ejection mechanism, comprising a lower stamping die base 1 and an upper stamping die base 12. The upper stamping die base 12 is positioned directly above the lower stamping die base 1. Symmetrical mating grooves 11 are formed in the upper cavity of the lower stamping die base 1, and a positioning groove 13 is formed from top to bottom at the upper end of the lower stamping die base 1. Vertical plates 2 are symmetrically fixedly connected to the upper end of the lower stamping die base 1. A movable cavity 21 is formed through the upper end of the vertical plates 2 from top to bottom. Sliding grooves 22 are symmetrically formed on both sides of the vertical plates 2, and are vertically arranged from top to bottom. Extrusion plates 23 are welded to the relatively distant sides of the two vertical plates 2. An installation is performed within the movable cavity 21. The device includes a rotary transmission mechanism, a lifting mechanism mounted on the lower stamping die holder 1, a positioning mechanism symmetrically mounted on the upper end of the lifting mechanism, and a flipping mechanism mounted above the lifting mechanism. The flipping mechanism includes a concave rotating frame 6, with docking seats 7 symmetrically fixedly connected to both ends of the concave rotating frame 6. The docking seats 7 are movably engaged with the docking groove 11. The upper end of the docking seats 7 has a mold groove that matches the mold cavity. The mold groove on the docking seats 7 and the mold cavity on the lower stamping die holder 1 form a complete mold cavity for an automotive part. The docking seats 7 can be matched according to the model of the automotive part. A stamping part collection box or conveyor belt is mounted on the side of the lower stamping die holder 1 to collect the automotive stamping parts.

[0029] Please refer to this carefully. Figure 3 The rotary transmission mechanism includes a rack plate 24 disposed in the movable cavity 21, a gear disk 3 disposed on the side of the rack plate 24, a round rod 31 disposed on the side of the gear disk 3, and a clamping plate 32 disposed at one end of the round rod 31. The round rod 31 passes through the gear disk 3 and is fixedly connected to the gear disk 3. One end of the round rod 31 passes through the slide groove 22 and is fixedly connected to the clamping plate 32.

[0030] The rack plate 24 is fixedly connected to the inner wall of the movable cavity 21. The gear disk 3 meshes with the rack plate 24 and rotates in contact with the movable cavity 21. The round rod 31 slides in contact with the slide groove 22. When the round rod 31 slides up and down along the slide groove 22, the round rod 31 drives the gear disk 3 to roll up and down along the rack plate 24. At the same time, the gear disk 3 drives the round rod 31 to rotate, and the round rod 31 drives the clamping plate 32 to rotate.

[0031] Please refer to this carefully. Figure 5 and Figure 6 The lifting mechanism includes a lifting seat 4 located on the upper end of the lower die holder 1 and two electric telescopic rods 43 symmetrically located on the lower end of the lifting seat 4. The electric telescopic rods 43 are fixedly connected to the lifting seat 4 and embedded in the lower die holder 1. The electric telescopic rods 43 are fixedly connected to the lower die holder 1 and are detachable. The lifting seat 4 moves up and down by extending and retracting the electric telescopic rods 43.

[0032] The upper end of the lifting seat 4 is symmetrically provided with protruding blocks. The sides of the two protruding blocks are provided with through grooves 41, and the sides of the through grooves 41 are provided with grooves 42. The lifting seat 4 is set between two vertical plates 2. The lower end of the lifting seat 4 is fixedly connected to a positioning plate 44. The positioning plate 44 is inserted into the positioning groove 13 and is slidably connected to the positioning groove 13. When the lifting seat 4 moves up and down, it drives the positioning plate 44 to move up and down. The positioning plate 44 slides up and down along the positioning groove 13. Through the cooperation of the electric telescopic rod 43 and the positioning plate 44, the lifting seat 4 can move up and down stably.

[0033] The positioning mechanism includes an L-shaped insert plate 5 disposed in the through groove 41, a slider 51 disposed on the side of the L-shaped insert plate 5, and a positioning spring 52 disposed on the side of the slider 51. The L-shaped insert plate 5 passes through the through groove 41 and is slidably connected to the through groove 41. The bent end of the L-shaped insert plate 5 is disposed below the extrusion plate 23, and the lower end of the extrusion plate 23 is set as a slope.

[0034] Both slider 51 and positioning spring 52 are disposed in groove 42, and slider 51 is slidably connected to groove 42. One end of positioning spring 52 is inserted into the inner wall of groove 42, and the other end of positioning spring 52 is inserted into slider 51. Positioning spring 52 applies elastic force to slider 51. When lifting seat 4 moves upward, lifting seat 4 drives positioning mechanism to move upward. When L-shaped insert 5 contacts extrusion plate 23, extrusion plate 23 pushes the bent end of L-shaped insert 5 to move outward, so that L-shaped insert 5 slides outward along through groove 41. Slider 51 is fixedly connected to L-shaped insert 5. When L-shaped insert 5 slides outward, it drives slider 51 to slide along groove 42, so that slider 51 squeezes positioning spring 52.

[0035] The flipping mechanism includes a concave rotating frame 6 disposed on the upper end of the lifting seat 4, and transmission cylinders 62 disposed on both sides of the concave rotating frame 6. Slots 61 are symmetrically opened on both sides of the concave rotating frame 6, and slots 63 are opened on the cylindrical surfaces of the two transmission cylinders 62.

[0036] Please refer to Figure 2 and Figure 3The concave rotating frame 6 is hinged to the lifting seat 4. Both ends of the concave rotating frame 6 are movably engaged with the upper end of the stamping die base 1. One end of the L-shaped insert plate 5 is inserted into the slot 61. The transmission cylinder 62 is positioned below the clamping plate 32. The concave rotating frame 6 is fixed by the L-shaped insert plate 5 being engaged with the slot 61 in the positioning mechanism. When the L-shaped insert plate 5 separates from the slot 61, the concave rotating frame 6 can flip upwards. The lifting seat 4 continues to move upwards, causing the clamping plate 32 to engage in the slot 63 of the transmission cylinder 62. As the lifting seat 4 continues to move upwards, the sides of the concave rotating frame 6... The transmission cylinder 62 drives the clamping plate 32 to move upward. The clamping plate 32 drives the gear disk 3 to move upward through the round rod 31. When the gear disk 3 moves upward, it rolls along the rack plate 24. The gear disk 3 drives the clamping plate 32 to rotate through the round rod 31. The clamping plate 32 drives the transmission cylinder 62 to rotate. The transmission cylinder 62 drives the concave rotating frame 6 to flip upward. The concave rotating frame 6 drives the automotive stamping part to flip upward through the docking seat 7, so that the flipping angle of the concave rotating frame 6 is close to or equal to 180 degrees, thereby separating the automotive stamping part from the docking seat 7, and thus completing the unloading and transfer of the automotive stamping part.

[0037] Working principle: When the stamped automotive parts need to be unloaded, the inner rod of the electric telescopic rod 43 extends upward, pushing the lifting seat 4 upward. The lifting seat 4 drives the positioning plate 44 to slide upward along the positioning groove 13, causing the lifting seat 4 to drive the flipping mechanism to move upward stably. At the same time, the lifting seat 4 drives the two positioning mechanisms to move upward, and the flipping mechanism drives the two docking seats 7 to move upward. The docking seats 7 drive the automotive stamped parts upward, separating the automotive stamped parts from the mold cavity of the stamping lower die holder 1. When the L-shaped insert plate 5 in the positioning mechanism contacts the extrusion plate 23, the extrusion plate 23 pushes the L-shaped insert plate 5 to slide along the through groove 41, causing one end of the L-shaped insert plate 5 to exit the slot. As the L-shaped insert 5 moves out of the groove 42, the slider 51 slides along the groove 42, and the slider 51 presses the positioning spring 52. At this time, the lifting seat 4 continues to move upward, causing the clamping plate 32 to engage in the slot 63 of the transmission cylinder 62. When the lifting seat 4 continues to move upward, the transmission cylinders 62 on both sides of the concave rotating frame 6 drive the clamping plate 32 to move upward. The clamping plate 32 drives the gear disk 3 to move upward through the round rod 31. When the gear disk 3 moves upward, it rolls along the rack plate 24. The gear disk 3 drives the clamping plate 32 to rotate through the round rod 31. The clamping plate 32 drives the transmission cylinder 62 to rotate. The transmission cylinder 62 drives the concave rotating frame 6 to flip upward. The concave rotating frame 6 drives the automotive stamping part to rotate through the docking seat 7. The concave rotating frame 6 is flipped upwards, causing its rotation angle to approach or equal to 180 degrees, thereby separating the automotive stamping part from the mating seat 7. This completes the unloading and transfer of the automotive stamping part, moving it out of the stamping die 1 and then flipping it away from above the stamping die 1. The entire process is automated, highly efficient, and significantly improves the stamping efficiency of automotive parts. Then, the electric telescopic rod 43 retracts, causing the lifting seat 4 to move downwards. The lifting seat 4 then moves the flipping mechanism downwards, and the transmission cylinder 62 in the flipping mechanism drives the gear disc 3 to roll downwards along the rack plate 24, thus rotating the concave rotating frame 6 to the lifting position. At the upper end of seat 4, when the concave rotating frame 6 is parallel to the lifting seat 4, the lifting seat 4 continues to move downward, thereby separating the clamping plate 32 from the clamping groove 63 of the transmission cylinder 62. At this time, the lifting seat 4 continues to move downward. When the L-shaped insert plate 5 separates from the extrusion plate 23, under the action of the positioning spring 52, the slider 51 slides back. The slider 51 drives the L-shaped insert plate 5 to move, so that one end of the L-shaped insert plate 5 is inserted into the slot 61, fixing the concave rotating frame 6 and the lifting seat 4. The lifting seat 4 continues to move downward until the concave rotating frame 6 drives the docking seat 7 to be inserted into the docking groove 11, thereby stopping the lifting seat 4 from moving downward. At this time, the feeding of the stamping lower die seat 1 can continue the stamping operation.
