Description

Technical Field

[0001] This utility model relates to the field of mold frame, specifically a mold frame with an improved central guide pillar structure. Background Technology

[0002] Improving the mold base structure of the central guide pillar usually involves optimizing the guiding device in the mold base, especially the central guide pillar. Such improvements may include, but are not limited to, improvements in the material, size, shape of the guide pillar, and its matching method with the guide sleeve. The purpose of optimization is to ensure that the mold can maintain a high degree of stability and precision during the stamping process, thereby improving production efficiency and product quality. Most existing mold bases only serve to support and fix the mold, and cannot greatly improve the casting speed or reduce the workload of the workers, and the operation is complicated.

[0003] To address the aforementioned issues, Chinese Patent Publication No. CN213701714U discloses an improved plastic mold frame with a central guide pillar structure. By rotating the handle in the lifting device, the rotating rod and the first and second bevel gears are driven to rotate, thereby causing the threaded rod to rotate and the threaded block to move up and down, which in turn pushes the third connecting rod to move the top block up and down. This reduces the workload of workers, improves work efficiency, increases economic benefits, and increases production.

[0004] While the comparative patent solves the problems of not being able to significantly increase casting speed, reduce the workload of workers, and being complex to operate, the device requires manual rotation of the handle in the lifting device to push the third connecting rod to move the top block up and down, which causes considerable trouble for workers.

[0005] Regarding the aforementioned technologies, this device has the drawback that it requires manual rotation of the handle in the lifting device to push the third connecting rod and move the top block up and down, which causes considerable inconvenience to the workers. Utility Model Content

A top seat 11 is fixedly connected to the top of the second mold 22, and a fixing plate 8 is fixedly sleeved on the outer wall of the second mold 22. A guide post 3 is fixedly connected to the top of the base 1, and a connecting plate 4 is slidably sleeved on the outer wall of the guide post 3. A second spring 23 is fixedly connected to the bottom of the connecting plate 4, and the bottom of the second spring 23 is fixedly connected to the top of the base 1. A spring base 5 is fixedly connected to the top of the connecting plate 4, and a compression spring 6 is fixedly connected to the top of the spring base 5. A spring top seat 7 is fixedly connected to the top of the compression spring 6.

[0027] One end of the connecting plate 4 is fixedly connected to the limiting plate 12, the top of the base 1 is fixedly connected to the fixed platform 13, the top of the fixed platform 13 is fixedly connected to the motor 14, the output end of the motor 14 is fixedly connected to the rotating rod 15 through the coupling, and one end of the rotating rod 15 is fixedly connected to the rotating disk 16.

[0028] The top of the spring top seat 7 is fixedly connected to the bottom of the fixed plate 8, and the compression spring 6 is slidably sleeved with the guide post 3. At this time, the compression spring 6 is in a stretched state, and the second mold 22 will have an upward force.

[0029] The top of the fixed plate 8 is provided with a through groove 9, and the guide post 3 is fixedly sleeved with the through groove 9. When the connecting plate 4 moves upward, it can drive the fixed plate 8 to move upward through the compression spring 6, thereby realizing the opening of the second mold 22.

[0030] The limiting plate 12 has an "L" shaped structure, and one end of the rotating rod 15 is fixedly connected to the eccentric part of the rotating disk 16. When the motor 14 is started, the motor 14 will drive the rotating disk 16 to rotate through the rotating rod 15. After the rotating disk 16 has rotated half a turn, the second spring 23 is in a compressed state, and then the connecting plate 4 will move upward.

[0031] During use, the motor 14 is started, and the motor 14 drives the rotating disk 16 to rotate through the rotating rod 15. After the rotating disk 16 has rotated half a turn, the second spring 23 is compressed, and the connecting plate 4 moves upward through the elastic force of the fixing plate 8, which in turn drives the fixing plate 8 to move upward, which in turn drives the second mold 22 to move, so that the second mold 22 can be opened. Thus, the device does not require manual operation by the staff throughout the process.

[0032] Example 2

[0033] Reference Figures 1-3In the second embodiment of this utility model, the top of the first mold 10 is provided with a mold groove 17, the inner wall of the mold groove 17 is slidably connected with a lifting magnetic plate 18, and the top of the lifting magnetic plate 18 is fixedly connected with a sealing plate 19. When the rotating disk 16 no longer plays a limiting role on the limiting plate 12, the limiting plate 12 will drive the connecting plate 4 to move upward.

[0034] The outer wall of the sealing plate 19 is slidably connected to the inner wall of the mold groove 17. A channel 20 is provided on the top of the connecting plate 4. A magnetic ring 21 is fixedly connected to the inner wall of the channel 20. The inner wall of the magnetic ring 21 is slidably connected to the outer wall of the first mold 10. The magnetic ring 21 and the lifting magnetic plate 18 attract each other. Because the magnetic ring 21 and the lifting magnetic plate 18 attract each other, the connecting plate 4 can drive the magnetic ring 21 to move upward through the lifting magnetic plate 18 when it moves. As a result, the sealing plate 19 can move upward. When the second mold 22 moves upward to open the mold, the sealing plate 19 can drive the workpiece to move upward, which makes it easier to demold the workpiece.

[0035] During use, the magnetic ring 21 and the lifting magnetic plate 18 attract each other. When the connecting plate 4 moves, the magnetic ring 21 can be driven to move upward through the lifting magnetic plate 18. Consequently, the sealing plate 19 can move upward. When the second mold 22 moves upward to open the mold, the sealing plate 19 can drive the workpiece to move upward, making it easier to demold the workpiece.
