Abstract
Description
Technical Field
[0001] This utility model relates to the field of mold equipment technology, and in particular to a mold for producing automotive inserts. Background Technology
[0002] Stamping dies are used in cold stamping processes to apply pressure to sheet metal, causing it to separate or plastically deform, thereby obtaining the desired parts. Dies are required in the production of automotive inserts.
[0003] Patent CN213436627U discloses a stamping die for automotive sheet metal production, including a lower die plate. A lower mold is fixedly connected to the upper middle part of the lower die plate. A fixed seat and a side plate are fixedly connected from the inside to the outside of the upper part of the lower die plate. A sliding groove with front and back symmetrical is opened at the upper part of the side plate. A guide groove with front and back symmetrical is opened inside the sliding groove. A guide block is slidably connected in the guide groove. A sliding rod is fixedly connected between the guide block and another guide block. An upper die and a first spring with left and right symmetrical is fixedly connected from the inside to the lower part of the upper die plate. A pressure plate is fixedly connected to the lower end of the first spring and another first spring.
[0004] In the above case, the upper and lower molds are installed in the device using bolts. When the upper mold plate is pressed down, it causes the first spring and the pressure plate to descend, limiting the material's position. However, there is no structure to limit the first spring, causing it to sway around during contraction, making it unable to hold the pressure plate down. Furthermore, the device uses bolts to fix the upper and lower molds, making it cumbersome for operators to change different molds, thus reducing the device's practicality.
[0005] Therefore, this utility model provides a mold for producing automotive inserts to meet the requirements. Utility Model Content
[0006] The purpose of this utility model is to provide a mold for producing automotive inserts, so as to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a mold for producing automotive inserts, comprising a base plate, a lower mold for producing automotive inserts slidably connected to the center of the top of the base plate, side pillars fixedly connected to all four sides of the top of the base plate, support pillars slidably connected to the top of the side pillars, a common top plate fixedly connected to the top of the four support pillars, a pressure ring fixedly connected to the top of the top plate, a drive gear rotatably connected to the center of the top of the top of the top plate, a plurality of locking rods slidably connected inside the pressure ring, a threaded rod fixedly connected to the end of each locking rod near the drive gear, and a fixed connection between the top of the top plate and the inner side of the pressure ring. Several limiting seats are provided, with an inner threaded ring rotatably connected to the inner side of each limiting seat. A threaded rod is threadedly connected to the inner side of the corresponding inner threaded ring. A gear ring is fixedly connected to the outer side of each inner threaded ring, and the gear ring meshes with a drive gear at a right angle. An upper mold is slidably connected to the bottom of the top plate. The upper mold includes several connecting rods at the top positions that are adapted to the locking rods. The locking rods are locked inside the connecting rods. Fixed seats are fixedly connected to all four sides of the top plate. A sliding rod is slidably connected to the bottom of each fixed seat. The bottom of the four sliding rods is fixedly connected to the same pressure frame. A first spring is fixedly connected to the top of the inner cavity of the fixed seat, and the bottom of the first spring is fixedly connected to the sliding rod.
[0008] In a preferred embodiment, the drive gear is located at the center of the pressure ring, and a throttle is fixedly connected to the top of the drive gear, with the height of the throttle being lower than that of the pressure ring.
[0009] In a preferred embodiment, the number of clamping rods is three, which are arranged in a ring inside the pressure ring, and the connecting rod has a hole inside that is adapted to the clamping rod.
[0010] In a preferred embodiment, the number of limiting seats is three, which are distributed in a ring inside the pressure ring and are positioned to match the threaded rod.
[0011] In a preferred embodiment, the internal thread ring includes a rotating ring rotatably connected inside the limiting seat, and the toothed ring is located on one side of the rotating ring.
[0012] In a preferred embodiment, the height of the top of both the connecting rod and the fixed seat is lower than the height of the top of the pressure ring.
[0013] In a preferred embodiment, a second spring is fixedly connected to the bottom end of the inner cavity of the side column, and the bottom end of the second spring is fixedly connected to the slide rod.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] This utility model, by setting a limiting seat, internal threaded rings, gear rings, threaded rods, and locking rods, allows the device to be inserted into the upper mold via a connecting rod. Through the cooperation of the drive gear and gear rings, the three internal threaded rings are driven synchronously, and the three threaded rods drive the locking rods to move under the limitation of the pressure rings and engage with the connecting rods, thereby fixing the upper mold and facilitating quick assembly and disassembly of the upper mold. Combined with the sliding connection between the upper and lower molds, the device facilitates mold replacement and improves work efficiency.
[0016] This utility model, by setting a fixed seat, a sliding rod, a first spring, and a pressure frame, allows the sliding rod to slide inside the fixed seat and compress the first spring when the pressure frame presses down on the board. This prevents the sliding rod and the first spring from causing the pressure frame to shake, thus ensuring the stability of the pressure frame. Furthermore, the frame shape design of the pressure frame facilitates fixing the board around its perimeter, further ensuring the stability of the board. Attached Figure Description

[0022] The present invention will be further described below with reference to the embodiments.
[0023] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention; the conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the concept of the present invention are all within the scope of protection claimed by the present invention.
[0024] Please see Figures 1-4This utility model provides a mold for producing automotive inserts, including a base plate 1. A lower mold 17 for producing automotive inserts is slidably connected to the center of the top of the base plate 1. Side pillars 2 are fixedly connected to all four sides of the top of the base plate 1. Support pillars 3 are slidably connected to the top of the side pillars 2. The top of the four support pillars 3 is fixedly connected to the same top plate 4. A pressure ring 5 is fixedly connected to the top of the top plate 4. A drive gear 6 is rotatably connected to the center of the top of the top of the top plate 4. An upper mold 18 is slidably connected to the bottom of the top plate 4. Fixed seats 13 are fixedly connected to all four sides of the top plate 4. A sliding rod 14 is slidably connected to the bottom of the fixed seat 13. The bottom of the four sliding rods 14 is fixedly connected to the same pressure frame 16. A first spring 15 is fixedly connected to the top of the inner cavity of the fixed seat 13. The bottom of the first spring 15 is fixedly connected to the sliding rod 14. A second spring is fixedly connected to the bottom of the inner cavity of the side pillars 2. The bottom of the second spring is fixedly connected to the sliding rod 14.
[0025] The sheet metal is placed on the lower mold 17. The pressing ring 5 is pressed down by the stamping machine, which causes the top plate 4 to drive the support column 3 to descend. When the pressing frame 16 contacts the sheet metal, it presses the slide rod 14 upward. The slide rod 14 slides in the fixed seat 13 and presses the first spring 15. The first spring 15 generates a rebound force, which pushes the pressing frame 16 to press the sheet metal. Then the upper mold 18 continues to descend until the sheet metal is pressed into shape.
[0026] When the pressure frame 16 presses down and contacts the sheet material, the slide bar 14 will slide smoothly within the preset slide of the fixed seat 13. This design not only ensures the linear movement of the pressure frame 16 when pressure is applied, but also effectively avoids shaking or displacement that may be caused by external force. The frame design of the pressure frame 16 can tightly press the four sides of the sheet material, effectively preventing the sheet material from moving laterally or warping during the pressing process. This design not only improves the positioning accuracy of the sheet material, but also ensures the dimensional stability and shape accuracy of the insert during the molding process.
[0027] Please see Figures 1-4The pressure ring 5 has several sliding connecting rods 7 inside. A threaded rod 8 is fixedly connected to one end of each connecting rod 7 near the drive gear 6. Several limiting seats 9 are fixedly connected to the top of the top plate 4 inside the pressure ring 5. An internal threaded ring 10 is rotatably connected to the inner side of each limiting seat 9. The threaded rod 8 is threaded to the inner side of the corresponding internal threaded ring 10. A gear ring 11 is fixedly connected to the outer side of the internal threaded ring 10, and the gear ring 11 meshes with the drive gear 6 at a right angle. The upper mold 18 includes several connecting rods 12 at the top that are adapted to the connecting rods 7. The connecting rods 7 are engaged inside the connecting rods 12. Gear 6 is located at the center of pressure ring 5. A handle is fixedly connected to the top of drive gear 6. The height of the handle is lower than that of pressure ring 5. There are three locking rods 7, which are distributed in a ring inside the pressure ring 5. The connecting rod 12 has a hole inside that fits the locking rod 7. There are three limiting seats 9, which are distributed in a ring inside the pressure ring 5 and are positioned to match the threaded rod 8. The inner thread ring 10 includes a rotating ring that is rotatably connected inside the limiting seat 9. The gear ring 11 is located on one side of the rotating ring. The height of the top of the connecting rod 12 and the fixed seat 13 is lower than the height of the top of the pressure ring 5.
[0028] When it is necessary to change the mold, the lower mold 17 is directly removed and replaced. Then, the handle of the drive gear 6 is turned. Through its meshing with the gear ring 11, the three gear rings 11 drive the inner thread ring 10 to rotate synchronously under the limit of the limit seat 9. This causes the threaded rod 8 to drive the clamping rod 7 to move towards the inside of the pressure ring 5 until the clamping rod 7 disengages from the connecting rod 12. The upper mold 18 is then removed, the new one is inserted, and then it is fixed by the drive gear 6.
[0029] Because the inner threaded ring 10 and the threaded rod 8 are connected by threads, the threaded rod 8 will move linearly along its axis as the inner threaded ring 10 rotates. This movement is cleverly restricted inside the pressure ring 5, ensuring that the clamping rod 7 can slide stably and orderly on the preset path. As the threaded rod 8 is pushed forward, the clamping rod 7 gradually approaches and finally engages in the hole inside the connecting rod 12. This process not only achieves a firm fixation of the upper mold 18, but also ensures that the mold will not shift or shake during the pressure process, thereby ensuring the accuracy and quality of the insert product. Combined with the sliding connection of the upper and lower molds 17, the device not only achieves quick disassembly and assembly and firm fixation of the upper mold 18 and the lower mold 17, but also greatly improves work efficiency and production flexibility.
[0030] The working principle and usage process of this utility model are as follows: The sheet metal is placed on the lower mold 17. The pressing ring 5 is pressed down by the stamping machine, which causes the top plate 4 to drive the support column 3 to descend. When the pressing frame 16 contacts the sheet metal, it presses the slide rod 14 upward. The slide rod 14 slides in the fixed seat 13 and presses the first spring 15. The first spring 15 generates a rebound force, which pushes the pressing frame 16 to press the sheet metal. Then the upper mold 18 continues to descend until the sheet metal is pressed into shape. When it is necessary to change the mold, the lower mold 17 is directly removed and replaced. Then the handle of the drive gear 6 is turned. Through its meshing with the gear ring 11, the three gear rings 11 drive the inner thread ring 10 to rotate synchronously under the limit of the limit seat 9. This causes the threaded rod 8 to drive the clamping rod 7 to move towards the inside of the pressing ring 5 until the clamping rod 7 disengages from the connecting rod 12. The upper mold 18 is removed, the new one is inserted, and then it is fixed by the drive gear 6.
