Description

Technical Field

[0001] The utility model relates to the technical field of mold manufacturing, and more specifically, the utility model relates to a new positioning mechanism for a double-cavity mold. Background Art

[0002] Workpiece positioning refers to the process of obtaining a correct machining position of a workpiece in a machine tool or fixture. This is a key step to ensure that the workpiece can be accurately and stably fixed at a predetermined position during the machining process to guarantee the machining accuracy and quality. During the manufacturing and use of a double-cavity mold, the positioning mechanism plays a crucial role, which is directly related to the machining accuracy, service life and production cost of the mold.

[0003] When the mold positioning mechanism is actually used, when fixing the car door sheet metal to the positioning mechanism, it is necessary to align the car door sheet metal with the bayonet of the positioning mechanism and then perform positioning. Since the aligned opening is small, inaccurate alignment may occur, resulting in shaking of the car door sheet metal during installation, reducing the work efficiency. Summary of the Utility Model

[0004] In order to overcome the above-mentioned defects of the prior art, the utility model provides a new positioning mechanism for a double-cavity mold to solve the problems raised in the above background art.

One side of the two second springs is fixedly connected to a second clamping block.

[0009] By adopting the above technical solution: The force exerted by the two balance frames on the two second pressing blocks downward can be more uniform. At the same time, during the upward movement of the pressing rod, the two bottom blocks, the first pressing block, and the second pressing block can be quickly separated through the second springs and the second clamping blocks, which is convenient for removing the assembled car door sheet metal from the positioning device.

[0010] As a further description of the above technical solution: A movable seat is fixedly connected to the top of the sliding plate. A support arm is movably connected to the outside of the movable seat. A pressing rod is fixedly connected to the outside of the support arm. A limiting sliding rod is fixedly connected to the inside of the support arm. A counterweight block is fixedly connected to one end of the support arm. A movable block is fixedly connected to the bottom of the support arm. A telescopic rod is fixedly connected to the bottom of the movable block.

[0011] By adopting the above technical solution: The rotation of the support arm and the pressing rod can be made labor-saving through the counterweight block and the telescopic rod. At the same time, the movable seat guides both sides of the support arm stably, making the up-and-down rotation of the support arm more stable.

[0012] The technical effects and advantages of the present utility model:

[0013] By setting the positioning mechanism, compared with the prior art, during the positioning of the car door sheet metal, a certain distance is maintained between the bottom block, the first pressing block, and the second pressing block through the sleeve, enabling the car door sheet metal to be quickly aligned with the positioning mechanism for fixation, improving the stability of the installation of the car door sheet metal.

[0014] By setting the movable seat, the support arm, the pressing rod, the limiting sliding rod, the counterweight block, the movable block, and the telescopic rod, compared with the prior art, during the downward pressing of the pressing rod on the positioning mechanism, the support arm can be easily opened through the telescopic rod and the counterweight block, and the positioning mechanism can be easily opened to remove the car door sheet metal. At the same time, the limiting sliding rod makes the up-and-down rotation of the support arm more stable, the operation becomes more convenient, and the manual physical energy consumption is reduced.

Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] The embodiment of the present application discloses a new double-chamber mold positioning mechanism, including a bottom plate 1. Two limit strips 2 are fixedly connected to the upper surface of the bottom plate 1. A first fixed block 3 is fixedly connected to one side of the bottom plate 1. A hydraulic rod 4 is installed on one side of the first fixed block 3. A first clamping block 5 is fixedly connected to one side of the hydraulic rod 4. A positioning mechanism is provided on the top of the bottom plate 1; the positioning mechanism includes a sliding plate 6. The outer side of the sliding plate 6 is movably connected to one side of the two limit strips 2. Two bottom blocks 7 are fixedly connected to the top of the sliding plate 6. The two bottom blocks 7 are symmetrically arranged on the upper surface of the sliding plate 6. A first pressing block 8 is arranged on the top of the bottom block 7. A second pressing block 9 is arranged on the top of the first pressing block 8. Two fixing plates 10 are fixedly connected to the top of the second pressing block 9. The two fixing plates 10 are symmetrically arranged on the top of the second pressing block 9. A sleeve 11 is fixedly connected to the bottom of the fixing plate 10. Two limit rings 12 are fixedly connected to the outer side of the sleeve 11. A first spring 13 is installed inside the sleeve 11. The bottom of the first spring 13 is movably connected to a pushing column 14. Driven by the corresponding first spring 13 and pushing column 14, the two bottom blocks 7, the first pressing block 8 and the second pressing block 9 cause the sleeve 11 to lift the first pressing block 8 and the second pressing block 9 upward through the two limit rings 12, facilitating the edge of the car door sheet metal to be clamped into the positioning mechanism and improving the installation efficiency of the car door sheet metal and the positioning mechanism.

[0024] Refer to Figure 5 As shown, balance frames 15 are fixedly connected to the tops of both second pressing blocks 9. Two fixing blocks II 16 are fixedly connected to the upper surface of the balance frame 15. Two second springs 17 are arranged inside the fixing blocks II 16. A second clamping block 18 is fixedly connected to one side of the two second springs 17. The balance frame 15 can evenly apply the downward pressing force to the top of the second pressing block 9, so that the two second pressing blocks 9, the first pressing block 8 and the bottom block 7 can maintain a stable clamping force, making the positioning of the car door sheet metal more stable.

[0025] Refer to Figure 6 As shown, a movable seat 19 is fixedly connected to the top of the sliding plate 6. A support arm 20 is movably connected to the outside of the movable seat 19. A pressing rod 21 is fixedly connected to the outside of the support arm 20. A limiting slide rod 22 is fixedly connected to the inside of the support arm 20. A counterweight block 23 is fixedly connected to one end of the support arm 20. A movable block 24 is fixedly connected to the bottom of the support arm 20. A telescopic rod 25 is fixedly connected to the bottom of the movable block 24. When the telescopic rod 25 pulls the support arm 20 to rotate outside the movable seat 19 through the movable block 24, the rotational force of the support arm 20 is balanced by the counterweight block 23, making it easier for the support arm 20 to move up and down.

[0026] Working principle of the utility model: Before installing the sealing strip and steel strip on the car door sheet metal, the car door sheet metal needs to be fixed on the positioning mechanism first. The telescopic rod 25 contracts downward and drives the support arm 20 to rotate around the axis of the movable seat 19 through the movable block 24. The support arm 20 rotates smoothly inside the movable seat 19 through the limiting slide rod 22. With the cooperation of the counterweight block 23 and the telescopic rod 25, the front end of the support arm 20 can drive the pressing rod 21 to move upward. At the same time, under the pushing of the push column 14 and the first spring 13 at the top, the multiple fixing plates 10 and sleeves 11 respectively push the first pressing block 8 and the second pressing block 9 upward, so that the bottom block 7, the first pressing block 8 and the second pressing block 9 can be quickly separated, facilitating the edge of the car door sheet metal to be clamped between the bottom block 7, the first pressing block 8 and the second pressing block 9;

[0027] Then, the telescopic rod 25 pushes the support arm 20 and the pressing rod 21 to rotate downward, so that the pressing rod 21 can press downward on the top of the balance frame 15. The outside of the pressing rod 21 is clamped with the two second clamping blocks 18 on the tops of the two balance frames 15, so that the pressing rod 21 can remain stable during the process of pressing the balance frame 15 downward, making the bottom block 7, the first pressing block 8 and the second pressing block 9 keep closely attached, and enabling the car door sheet metal to be stably fixed, facilitating the subsequent installation of the sealing strip and steel strip.
