Description

Technical Field

[0001] This utility model relates to the field of mica board processing, and in particular to a hot press lifting platform. Background Technology

[0002] Mica board is an insulating and refractory material made primarily of mica. Due to the unique physical and chemical properties of mica (high insulation, high temperature resistance, and breakdown resistance), it is widely used in fields with stringent requirements for insulation and high temperature resistance, such as electrical, electronic, and aerospace industries.

[0003] A hot press is a device that uses high temperature and pressure to cause physical or chemical changes in materials, thereby achieving functions such as bonding, pressing, and molding.

[0004] However, most lifting platforms use fixed pressure plates or simple bolt fastening, making it difficult to adaptively adjust according to the size and thickness of the sheet material. During processing, the sheet material is prone to loosening and displacement, which not only leads to uneven hot pressing and affects the forming quality of the sheet material, but may also cause problems such as sheet material deformation and cracking, increasing the scrap rate, wasting raw materials, and increasing production costs. Therefore, a hot press lifting platform is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a hot press lifting platform, which aims to improve the situation in the prior art where the sheet material is prone to loosening and displacement during processing. This not only leads to uneven hot pressing and affects the forming quality of the sheet material, but may also cause the sheet material to deform.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a hot press lifting platform, including a base, a movable plate in contact with the surface of the base, a lifting assembly provided on the inner wall of the bottom end of the base, two sets of brackets fixedly connected to the rear end of the base, a circular roller fixedly connected between the two sets of brackets, a placement plate slidably connected to the surface of the movable plate, a positioning assembly provided on the front end surface of the placement plate, a sliding rod elastically connected to the inner wall of the placement plate by a limiting spring, and a lower pressure plate fixedly connected to the top end of the outer wall of the sliding rod;

[0007] The positioning component includes an L-block, the surface of which is fixedly connected to a handle, and the inner sidewall of the handle is elastically connected to an insert block via a return spring.

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

[0009] The lifting assembly includes a rotating block, the rotating block's rotation center shaft is fixedly connected to a bidirectional threaded rod, the surface of the bidirectional threaded rod is threaded with two sets of threaded seats, and the upper surface of the threaded seats is hinged with a hinge rod.

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

[0011] The lifting assembly includes a rotating block, the rotating block's rotation center shaft is fixedly connected to a bidirectional threaded rod, the surface of the bidirectional threaded rod is threaded with two sets of threaded seats, and the upper surface of the threaded seats is hinged with a hinge rod.

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

[0013] The sliding rod is slidably connected to the inner wall at the top of the placement plate, and the surface of the lower pressure plate is provided with an inner arc surface, which is in contact with the outer arc surface of the roller.

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

[0015] The L-block is fixedly connected to the center of the outer sidewall of the placement plate, and the insert block is slidably connected to the inner wall of the L-block.

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

[0017] The front surface of the movable plate has two sets of slots, and the end of the insert block is inserted into the inner wall of the slot.

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

[0019] One end of the reset spring is fixedly connected to the inner side wall of the handle, and the other end of the reset spring is fixedly connected to the outer wall of the insert.

[0020] As a further description of the above technical solution:

[0021] The rotating block is rotatably connected to the surface at the bottom of the base, the bidirectional threaded rod is rotatably connected to the inner side wall of the base, the threaded seat is slidably connected to the inner side wall of the base, and the end of the hinge rod away from the threaded seat is hinged to the bottom end of the outer wall of the moving plate.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, when the moving plate rises, the lower pressure plate contacts the circular roller. The pressure applied by the circular roller pushes the lower pressure plate to overcome the elastic force of the limiting spring and descend, firmly pressing the mica plate onto the placement plate. This elastic pressing method not only automatically adjusts the pressing force according to the thickness of the plate, ensuring that the plate will not loosen or shift during the hot pressing process, but also avoids damage to the plate caused by rigid pressing, effectively improving the quality and yield of hot pressing processing, and ensuring the processing accuracy and integrity of the plate.

[0024] 2. In this utility model, the placement plate composed of two sets of plates can achieve quick switching. After a mica plate is processed, simply pull the handle to release the fixing of the insert block and the slot, and the placement plate can be slid horizontally to move the unprocessed plate to the processing position. After fixing it again, processing can continue. This design reduces downtime for changing materials.

[0025] 3. In this utility model, the rotating block drives the bidirectional threaded rod to rotate, and the two sets of threaded seats move closer or further apart under the action of the reverse threads, driving the moving plate to rise and fall smoothly through the hinge rod. This structure is not only easy to operate, but also enables precise height adjustment, meeting the height requirements of the plate at different processing stages of the hot press.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figures 1-3 This utility model provides an embodiment of a hot press lifting platform, including a base 1, a movable plate 3 in contact with the surface of the base 1, a lifting assembly 2 on the inner wall of the bottom end of the base 1, two sets of brackets 6 fixedly connected to the rear end of the base 1, and a circular roller 7 fixedly connected between the two sets of brackets 6, allowing the circular roller 7 to be placed as a whole through the two sets of brackets 6. A placement plate 4 is slidably connected to the surface of the movable plate 3, and the placement plate 4 is composed of two sets of plates, so that after one set of mica plates is processed, the two sets of mica plates can be switched for hot pressing through the lateral sliding of the placement plate 4, thereby improving the overall processing efficiency. A positioning assembly 5 is provided on the front end surface of the placement plate 4, and a sliding assembly 5 is elastically connected to the inner wall of the placement plate 4 by a limiting spring 10. One end of the sliding rod 9 and the limiting spring 10 are fixedly connected to the bottom end of the outer wall of the sliding rod 9, and the other end of the limiting spring 10 is fixedly connected to the bottom end of the inner wall of the placement plate 4. The function of the limiting spring 10 is to automatically reset the position of the sliding rod 9 after it has moved. The top end of the outer wall of the sliding rod 9 is fixedly connected to the lower pressure plate 8. The sliding rod 9 is slidably connected to the inner wall of the top end of the placement plate 4. The surface of the lower pressure plate 8 has an inner arc surface. The inner arc surface of the lower pressure plate 8 is in contact with the outer arc surface of the roller 7. The contact between the two causes the moving plate 3 to drive the placement plate 4 to rise synchronously when it rises. At the same time, the contact between the roller 7 and the lower pressure plate 8 pushes the lower pressure plate 8 to drive the sliding rod 9 to descend on the inner wall of the placement plate 4, thereby pressing the mica plate placed on its surface.

[0035] Reference Figure 2 and Figure 4 The positioning component 5 includes an L-block 51, which is fixedly connected to the center of the outer sidewall of the placement plate 4. When the L-block 51 moves, it will drive the placement plate 4 to move synchronously. The insert 54 passes through and is slidably connected to the inner wall of the L-block 51. A handle 52 is fixedly connected to the surface of the L-block 51. The insert 54 is elastically connected to the inner sidewall of the handle 52 through a return spring 53. One end of the return spring 53 is fixedly connected to the inner sidewall of the handle 52, and the other end of the return spring 53 is fixedly connected to the outer wall of the insert 54. The function of the return spring 53 is to automatically reset the position of the insert 54 after it is pulled outward. Two sets of slots are opened on the front surface of the moving plate 3. The end of the insert 54 is inserted into the inner wall of the slot. The insertion between the two allows the placement plate 4 to be moved on the surface of the moving plate 3 to adjust and fix the position of the two sets of mica plates after they have moved.

[0036] Reference Figure 1 and Figure 5The lifting assembly 2 includes a rotating block 21. A bidirectional threaded rod 22 is fixedly connected to the rotation center shaft of the rotating block 21. Two sets of threaded seats 23 are threadedly connected to the surface of the bidirectional threaded rod 22. The inner side of the threaded seat 23 is provided with an internal thread groove, and the surface of the bidirectional threaded rod 22 is provided with two sets of external thread grooves with opposite directions of rotation. By rotating the bidirectional threaded rod 22, the two sets of threaded seats 23 can be brought closer together or moved away from each other on their surfaces. A hinge rod 24 is hinged to the upper surface of the threaded seat 23. The rotating block 21 is rotatably connected to the surface of the bottom end of the base 1. The bidirectional threaded rod 22 is rotatably connected to the inner side wall of the base 1. The threaded seat 23 is slidably connected to the inner side wall of the base 1. The end of the hinge rod 24 away from the threaded seat 23 is hinged to the bottom end of the outer wall of the moving plate 3. When the threaded seat 23 moves in a threaded manner, it will push the hinge rod 24 to move up and down, thereby adjusting the overall height of the moving plate 3, thereby adjusting the position of the mica plate.

[0037] Working principle: When the rotating block 21 is rotated, the bidirectional threaded rod 22 rotates synchronously. Since the threads turn in opposite directions, the two sets of threaded seats 23 will move closer or further apart on the surface of the bidirectional threaded rod 22.

[0038] A hinge rod 24 is hinged to the upper surface of the threaded seat 23. The end of the hinge rod 24 away from the threaded seat 23 is hinged to the bottom end of the outer wall of the moving plate 3. When the threaded seat 23 moves threadedly on the bidirectional threaded rod 22, it pushes the hinge rod 24 to move up and down, thereby changing the overall height of the moving plate 3. As the moving plate 3 rises and falls, the positions of the placement plate 4 and the mica plate placed on its surface are also adjusted accordingly to meet the height requirements of the plate material at different processing stages of the hot press. At the same time, when the moving plate 3 is under the action of the lifting assembly 2... When rising, the placement plate 4 rises synchronously. As the placement plate 4 rises, the lower pressure plate 8 contacts the circular roller 7. The circular roller 7 exerts downward pressure on the lower pressure plate 8, pushing the lower pressure plate 8 to overcome the elastic force of the limit spring 10, and causing the sliding rod 9 to descend on the inner wall of the placement plate 4. The lower pressure plate 8 presses the mica plate placed on its surface tightly onto the placement plate 4, ensuring that the mica plate remains stable during the hot pressing process and avoiding the impact of loosening on the processing quality. When the moving plate 3 descends, the limit spring 10 pushes the sliding rod 9 and the lower pressure plate 8 to reset, releasing the mica plate.

[0039] The placement plate 4 consists of two sets of mica sheets. After one set of mica sheets is processed on the hot press, the handle 52 in the positioning component 5 is pulled to disengage the insert 54 from the slot of the moving plate 3, thus releasing the fixed state of the placement plate 4. At this time, the placement plate 4 can be slid laterally to move the other set of unprocessed mica sheets to the hot press processing position. After adjusting the position, the handle 52 is released, and the insert 54 is reinserted into the slot under the action of the return spring 53 to fix the placement plate 4. The new mica sheet can then be hot-pressed. In this way, the two sets of mica sheets can be quickly switched, reducing waiting time and improving the overall processing efficiency.

[0040] 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. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
