Description

Technical Field

[0001] This utility model relates to the field of fastener production technology, and in particular to a continuous forming mold for fastener spring clips. Background Technology

[0002] A fastener spring clip is a mechanical part that uses the elastic deformation of a spring to achieve the functions of connection, fixation, or locking. It is usually made of a metal material with a certain degree of elasticity. Clamping force is generated by the elastic deformation of the spring, such as bending and twisting, to connect two or more parts together. When disassembly is required, the spring can be deformed by external force to release the connection. A fastener spring clip forming mold is a mold used to manufacture fastener spring clips. Through a specific mold structure and forming process, the metal material is processed into the required spring clip shape.

[0003] A search revealed that Chinese Patent CN221289253U discloses a continuous forming mold for fastener spring-loaded hooks. This addresses the issue that traditional molds can only produce a single model of product, requiring different molds to be changed when producing different models of spring-loaded hooks. This mold-changing process is cumbersome and reduces work efficiency. Therefore, by rotating a worm gear to drive the extrusion block, rapid switching of the extrusion block can be achieved. Then, a first reset spring pushes a limit block into the insertion hole and sliding hole, making the extrusion block more stable during the stamping process.

[0004] While the aforementioned continuous forming mold facilitates mold replacement, during the extrusion process of fastener spring-type hooks, long strip metal sheets are typically placed on the lower mold and extruded into multiple spring-type hooks, which are then cut to obtain the hooks. After placing the long strip metal sheet on the lower mold, the sheet is relatively thin, resulting in a small weight and making it prone to tilting and offset. This makes it difficult to align with the mold groove of the lower mold, and consequently, the deflection of the sheet after extrusion can reduce the processing accuracy, leading to unqualified hook processing. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a continuous forming mold for fastener spring clips.

[0007] The anti-deviation component includes a gear, which is fixedly connected to the output end of the stepper motor.

[0008] As a further description of the above technical solution:

[0009] Two mounting rods are fixedly connected to the lower surface of the lower mold. A connecting rod is slidably connected to the outside of the mounting rod. An inner groove is opened inside the connecting rod. Multiple toothed grooves are opened on one side of the connecting rod. The multiple toothed grooves are meshed with gears. A limit rod is fixedly connected to one end of the connecting rod.

[0010] As a further description of the above technical solution:

[0011] The lower mold is provided with a discharge assembly, which includes two fixed shells that are fixedly connected to the two outer sides of the lower mold.

[0012] As a further description of the above technical solution:

[0013] The fixed shell is internally rotatably connected to a bidirectional stud, and the external thread of the bidirectional stud is connected to two moving blocks.

[0014] As a further description of the above technical solution:

[0015] Two of the movable blocks are slidably connected inside the fixed shell, and a rotating rod is hinged to the upper surface of the movable block. One end of each of the two rotating rods is hinged to a supporting shell.

[0016] As a further description of the above technical solution:

[0017] A first stepper motor is fixedly installed on one side of the support shell. A screw is fixedly connected to the output end of the first stepper motor. A push block is threadedly connected to the external thread of the screw. The push block is slidably connected inside the support shell.

[0018] As a further description of the above technical solution:

[0019] One end of the bidirectional stud is fixedly connected to a synchronous pulley, and a synchronous belt is provided on the outside of the two synchronous pulleys.

A second stepper motor is fixedly installed on one side of the protective shell, and one of the synchronous pulleys is fixedly connected to the output end of the second stepper motor.

[0020] This utility model has the following beneficial effects:

[0021] 1. This utility model utilizes the anti-offset component, which uses two mutually close limiting rods to quickly limit the metal pieces placed on multiple mold slots. This allows the placement of offset metal pieces to be corrected under the push of the limiting rods, thereby helping the metal pieces to align with multiple mold slots for processing and reducing the phenomenon of unqualified hook processing and reduced accuracy caused by the offset of the metal pieces.

[0022] 2. This utility model utilizes the setting of the discharge component and the upward-moving support shell to facilitate the pushing of the metal sheet after it has been processed into multiple hooks and is inside the mold groove. This allows the metal sheet to be quickly removed from the mold groove, thereby reducing adhesion between the metal sheet and the mold groove. Furthermore, the movement of the push block facilitates the pushing of the metal sheet above the support shell to one side, which is conducive to the automatic discharge of the metal sheet. This helps to improve the convenience and continuity of hook processing. Attached Figure Description

[0033] As attached Figure 1-7 As shown, one embodiment of this utility model is provided: a continuous forming mold for fastener spring clips, including a lower mold 1. The upper surface of the lower mold 1 is provided with multiple mold grooves 2. Two fixing rods 3 are fixedly connected to both sides of the lower mold 1. A connecting frame 4 is slidably connected to the outside of the fixing rods 3. An upper mold 5 is fixedly connected between the multiple connecting frames 4 to facilitate the positioning of the upper mold 5 and the lower mold 1. Multiple modules 6 are fixedly connected to the lower surface of the upper mold 5. A groove 7 is provided on the lower surface of the lower mold 1. A stepper motor 8 is fixedly installed inside the groove 7. An anti-offset component is provided at the output end of the stepper motor 8.

[0034] The anti-deviation component includes a gear 9, which is fixedly connected to the output end of the stepper motor 8.

[0035] As attached Figure 2 As shown, two mounting rods 10 are fixedly connected to the lower surface of the lower mold 1, and the inner groove 12 is used to limit the connecting rod 11.

[0036] As attached Figure 5 As shown, a connecting rod 11 is slidably connected to the outside of the mounting rod 10. The connecting rod 11 has an inner groove 12 to facilitate the sliding of the mounting rod 10. Multiple toothed grooves 13 are provided on one side of the connecting rod 11. The multiple toothed grooves 13 are meshed with the gear 9 to facilitate the gear 9 to drive the connecting rod 11 to move. A limit rod 14 is fixedly connected to one end of the connecting rod 11 to limit the movement of the connecting rod 11.

[0037] As attached Figure 7As shown, a material discharge assembly is provided on the outside of the lower mold 1. The material discharge assembly includes two fixed shells 15, which are fixedly connected to the two sides of the lower mold 1. A bidirectional stud 16 is rotatably connected inside the fixed shell 15, and the outside is set with threads in opposite directions. Two moving blocks 17 are connected to the external threads of the bidirectional stud 16. The two moving blocks 17 are slidably connected inside the fixed shell 15, so that the fixed shell 15 limits the moving blocks 17. A rotating rod 18 is hinged to the upper surface of the moving block 17. A support shell 19 is hinged to one end of the two rotating rods 18, which facilitates the upward or downward movement of the support shell 19. A first stepper motor 20 is fixedly installed on one side of the support shell 19. A screw 21 is fixedly connected to the output end of the first stepper motor 20. A push block 22 is connected to the external threads of the screw 21, which facilitates the pushing of the metal sheet. The push block 22 is slidably connected inside the support shell 19. A synchronous wheel 23 is fixedly connected to one end of the bidirectional stud 16.

[0038] As attached Figure 6 As shown, a synchronous belt 24 is provided on the outside of the two synchronous pulleys 23 to facilitate the simultaneous rotation of the two bidirectional studs 16 on both sides. A protective shell 26 is fixedly connected to one side of the lower mold 1 to protect the synchronous belt 24. The synchronous belt 24 is located inside the protective shell 26. A second stepper motor 25 is fixedly installed on one side of the protective shell 26, and one of the synchronous pulleys 23 is fixedly connected to the output end of the second stepper motor 25.

[0039] Working principle: In use, after connecting the upper mold 5 to the pressing device, when a metal sheet with a width slightly larger than the width of the lower mold 1 is placed on the lower mold 1 and above the mold groove 2, the two sides of the metal sheet are above the two side support shells 19. The controller starts the stepper motor 8, which drives the gear 9 to rotate. Then, under the action of the gear 9 meshing with the tooth groove 13, the multiple tooth grooves 13 push the two connecting rods 11 closer to each other. Under the action of the inner groove 12, the connecting rods 11 slide outside the mounting rod 10. The connecting rods 11 drive the limiting rod 14 to push the metal sheet, so that the two sides of the metal sheet are pushed by the limiting rod 14, so that the position of the two sides is corrected, making it easier for the metal sheet to align with the mold groove 2 and be in the same direction. Then, under the reverse rotation of the output end of the stepper motor 8, the two limiting rods 14 are indirectly driven to move away from each other quickly. Then the pressing device drives the upper mold 5 and multiple modules 6 to press down, thereby extruding and forming the metal sheet.

[0040] When the metal sheet is being discharged, the second stepper motor 25 is started, and its output end drives the corresponding synchronous wheel 23 to rotate. Under the connection of the synchronous belt 24, the synchronous wheel 23 on the other side rotates, which in turn drives the bidirectional studs 16 on both sides to rotate. This causes the bidirectional studs 16 to push the moving block 17 to slide inside the fixed shell 15, causing the rotating rod 18 to rotate, which in turn pushes the support shell 19 to move upward. When the support shell 19 moves upward, it pushes the metal sheet above it to move upward, which facilitates the demolding of the metal sheet. After demolding, the first stepper motor 20 is started, and its output end drives the screw 21 to rotate. This causes the screw 21 to drive the push block 22 to slide inside the support shell 19, which facilitates pushing the metal sheet to one side, thereby making the metal sheet automatically discharged.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
