The design of this device aims to improve production efficiency, ensure the dimensional accuracy and surface quality of the guide plate. The waste generated during the stamping process will be automatically collected to reduce material waste. Finally, the completed guide plate is used in the slide rail system of the refrigerator drawer to help the drawer open and close smoothly and provide stable support;

[0003] After retrieval, the Chinese patent with the publication number of CN220805107U discloses a stamping device for a refrigerator drawer guide plate.

[0014] (III) Beneficial effects

[0015] The utility model provides a stamping device for a refrigerator drawer guide plate. It has the following beneficial effects:

[0016] (1) The workbench supports the mold and provides a stable foundation during the stamping process of the stamping module. After stamping is completed, the stamping module moves upward and is accurately positioned by the limit rod, thus avoiding excessive movement of the module. Start the motor outside the fixed plate, and the motor drives the bidirectional threaded rod to rotate. The rotation of the bidirectional threaded rod causes the connecting blocks at both ends to move in the opposite direction. At the same time, the connecting blocks, through the cooperation of the positioning block and the positioning rod, accurately guide the movement path. When the connecting block moves, it pushes the limiting block I at the top. The movement of the limiting block I further pushes the bottom end of the rotating rod upward. Since the length of the rotating rod is fixed, this movement causes its top end to be pushed upward, and at the same time, it pushes the ejector plate upward. The ejector plate ejects the stamped refrigerator drawer guide plate from the mold by pushing upward. This series of actions solves the problem of removing the refrigerator drawer guide plate after stamping through precise mechanical cooperation, realizes fast and stable discharging, improves production efficiency, and reduces manual intervention and potential operation errors.

[0017] (2) The function of the roller is to smoothly feed the semi-finished product of the refrigerator drawer guide plate along the groove plate into the mold and perform precise positioning, thereby preventing deviation during processing. The groove plate guides the semi-finished product into the mold to ensure its correct placement at the processing position. The telescopic rod and the spring act together on the pressing block. The spring provides the necessary elastic support, and the telescopic rod is responsible for adjusting the pressure of the pressing block, so that the pressing block can firmly press on the semi-finished product. Such a cooperation avoids the warping or movement of the semi-finished product during the stamping process, ensures the accuracy of processing. Through the coordinated work of these components, the positioning and fixing problems during the entire stamping process are solved, thereby improving the consistency and processing accuracy of the product, and finally realizing an efficient and stable production effect.

Specific implementation mode

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0024] Please refer to Figures 1-4 , the present invention provides a technical solution:

[0025] Embodiment 1: A stamping device for a refrigerator drawer guide plate, including a workbench 1, a mold 2 is fixedly connected to the top of the workbench 1, a pair of fixed plates 3 are fixedly connected to the bottom of the workbench 1, and a motor 4 is fixedly connected to the outer wall of one of the fixed plates 3. The output end of the motor 4 is fixedly connected to a bidirectional threaded rod 5. At the same time, the bidirectional threaded rod 5 is rotatably connected between the two fixed plates 3. Both ends of the bidirectional threaded rod 5 are threadedly connected with connecting blocks 6. The top of each connecting block 6 is fixedly connected with a first limiting block 9. One end of a rotating rod 10 is rotatably connected inside each first limiting block 9. The other end of the rotating rod 10 is rotatably connected to a second limiting block 11. The upper surface of the second limiting block 11 is fixedly connected with an ejector plate 12. At the same time, the ejector plate 12 penetrates through the workbench 1 and is slidably connected inside the mold 2. A support frame 13 is arranged outside the workbench 1. A hydraulic cylinder 17 is fixedly connected to the top of the support frame 13. The output end of the hydraulic cylinder 17 is fixedly connected to a stamping module 18. At the same time, the stamping module 18 corresponds to the mold 2. A pair of positioning rods 8 are fixedly connected between the two fixed plates 3. Positioning blocks 7 are fixedly connected to both side walls of each connecting block 6. The positioning blocks 7 are slidably connected to the outer walls of the positioning rods 8. A pair of limiting rods 22 are fixedly connected to the top of the stamping module 18. The limiting rods 22 are slidably connected inside the support frame 13.

[0026] After stamping is completed, the stamping module 18 moves upward and is positioned by the limit rod 22. The motor 4 outside the fixed plate 3 is started, and the motor 4 drives the bidirectional threaded rod 5 to rotate. The rotation of the bidirectional threaded rod 5 causes the connecting blocks 6 at both ends to move in opposite directions. During the movement of the connecting blocks 6, they cooperate with the positioning blocks 7 on the positioning rods 8. When the connecting blocks 6 move, they push the top limit block 9 and cause the limit block 9 to move, thereby driving the bottom end of the rotating rod 10 to move upward. Since the length of the rotating rod 10 is fixed, when its bottom end moves inward, the top end will push upward. This action pushes the ejector plate 12 and makes it move upward, thereby ejecting the stamped refrigerator drawer guide plate from the mold 2. This process realizes rapid discharging and significantly improves work efficiency.

[0027] Embodiment 2: The difference between this embodiment and Embodiment 1 is that a number of struts 14 are fixedly connected to the top of the workbench 1, and a roller 15 is rotatably connected to the top of each strut 14. At the same time, a groove plate 16 is fixedly connected inside the support frame 13, and the groove plate 16 and the roller 15 are on the same horizontal plane. Both bottom sides of the stamping module 18 are fixedly connected with telescopic rods 19, and the other end of the telescopic rod 19 is fixedly connected with a pressing block 21. A spring 20 is fixedly connected between the stamping module 18 and the pressing block 21, and the spring 20 is sleeved on the outer wall of the telescopic rod 19. A cross plate 23 is fixedly connected to the inner side wall of the support frame 13, a chute 26 is opened inside the cross plate 23, and an electric push rod 1 is fixedly connected to the inner wall of the support frame 13. The output end of the electric push rod 1 is fixedly connected with a connecting frame 25, and the connecting frame 25 is slidably connected in the chute 26. The outer wall of the bottom end of the connecting frame 25 is fixedly connected with an electric push rod 27, and the output end of the electric push rod 27 penetrates through the connecting frame 25 and is fixedly connected with a push plate 28.

[0028] The semi-finished product of the refrigerator drawer guide plate is pushed into the top of the mold 2 through the groove plate 16 and accurately positioned along the rollers 15 to ensure that there is no deviation during the processing. The hydraulic cylinder 17 on the support frame 13 is started to push the stamping module 18 downward. During this process, the stamping module 18 applies a downward pressure to the semi-finished product through the pressing blocks 21 on both sides, and the spring 20 on the telescopic rod 19 provides additional elastic support to stabilize the pressing block 21 and prevent the semi-finished product from warping during stamping, and can effectively position the semi-finished product accurately. When stamping is completed, the electric push rods 27 on both sides are started to move the push plate 28 and clamp the refrigerator drawer guide plate. The electric push rod 1 is started to push the connecting frame 25 outward. The combination of these actions enables the refrigerator drawer guide plate to be smoothly moved out of the equipment to complete the entire processing process.

[0029] Working principle: When workers need to manufacture the refrigerator drawer guide plate, first, the semi-finished refrigerator drawer guide plate is pushed into the top of the mold 2 through the groove plate 16 and is positioned and corrected along the rollers 15 to prevent deviation during processing. At this time, the hydraulic cylinder 17 at the top of the support frame 13 is started. Under the action of the hydraulic cylinder 17, the stamping module 18 is pushed downward to cooperate with the groove in the mold 2 to stamp the semi-finished refrigerator drawer guide plate into shape. At the same time, when the stamping module 18 stamps, it will press down the semi-finished refrigerator drawer guide plate through the pressing blocks 21 on both sides, and cooperate with the elastic force of the spring 20 on the telescopic rod 19 to make the pressing blocks 21 fix more firmly, preventing the situation of warping edges during stamping. Through their cooperation, the effective positioning of the semi-finished refrigerator drawer guide plate is realized. At this time, after stamping, the stamping module 18 moves upward and is limited by the limiting rod 22. Then, the motor 4 outside the fixed plate 3 is started. Under the action of the motor 4, the bidirectional threaded rod 5 rotates. When the bidirectional threaded rod 5 rotates, the connecting blocks 6 at both ends move in the opposite direction. The connecting blocks 6 are limited on the positioning rod 8 by the positioning blocks 7 during movement. The movement of the connecting blocks 6 drives the movement of the limiting block one 9 at the top, and the movement of the limiting block one 9 drives the movement of the bottom end of the rotating rod 10. Since the length of the rotating rod 10 remains unchanged, when the bottom end of the rotating rod 10 moves inward, the top end of the rotating rod 10 will push upward, and at the same time, the ejector plate 12 is pushed upward to eject the stamped refrigerator drawer guide plate from the mold 2, thus realizing the rapid discharging of the refrigerator drawer guide plate and improving the work efficiency. After the refrigerator drawer guide plate is ejected, by starting the electric push rods two 27 on both sides, under the action of the electric push rods two 27, the push plates 28 are pushed to move. The two push plates 28 will squeeze the refrigerator drawer guide plate, and cooperate with the start of the electric push rod one 24 to push the connecting frame 25 outward, thereby moving the refrigerator drawer guide plate out of the equipment.
