Description

Technical Field

[0001] This utility model relates to the field of vacuum hot press technology, and more specifically, to a vacuum hot press. Background Technology

[0002] A vacuum hot press is a high-end piece of equipment used for precision forming and machining. Its core structure includes an upper and lower mold, a temperature control device, a vacuum unit, and a pressure actuator. This equipment has important applications in many high-tech fields such as electronics, automotive manufacturing, and aerospace. Particularly in chip processing, the chip to be processed is placed inside the mold, and through heating and vacuuming processes, it achieves a tight bond between the interfaces under high pressure, thereby achieving the preset shape and microstructure requirements. The existing vacuum hot press still has the following problems when in use: Currently, even after processing and mold opening, operators still need to directly insert their arms into the high-temperature vacuum chamber to handle products using existing hot presses. Because the hot press platen and molding components are typically very hot, contact with the hot surfaces or products poses a significant risk of burns. The existing material handling method clearly provides insufficient labor protection for operators and presents considerable hidden dangers. Furthermore, in actual operation, vacuum hot presses simply place the material to be pressed flat on the hot press platen without taking effective positioning or securing measures. When the vacuuming process begins or the hydraulic system is activated to apply pressure, mechanical vibrations and airflow disturbances easily occur inside the equipment, causing slight shaking of the hot press platen, resulting in material displacement or misalignment, directly affecting molding accuracy and product quality.

[0003] In view of this, we propose a vacuum hot press. Utility Model Content

[0021] Please see Figures 1-6 A vacuum hot press includes a base 1, a control panel 2 fixedly connected to the base 1, an emergency stop button 3 installed on the base 1, a vacuum chamber 4 fixedly connected to the upper side of the base 1, a sealing door 5 hinged to the vacuum chamber 4, four guide columns 6 fixedly connected inside the vacuum chamber 4, a top plate 7 fixedly connected to the top of the four guide columns 6, a first hot press plate 8 fixedly connected to the lower side of the top plate 7, a movable plate 9 slidably connected to the four guide columns 6, a second hot press plate 10 fixedly connected to the upper side of the movable plate 9, a hydraulic cylinder 11 embedded between the base 1 and the vacuum chamber 4, the telescopic end of the hydraulic cylinder 11 fixedly connected to the movable plate 9, a sliding plate 12 slidably connected to the upper side of the second hot press plate 10, guide plates 13 fixedly connected to both sides of the sliding plate 12, the guide plates 13 slidably connected to the first hot press plate 8, and the movable plate 9 having a driving structure and a centering structure; the width of the first hot press plate 8 is smaller than the width of the second hot press plate 10.

[0022] Please see Figure 4 and Figure 5 The drive structure includes two fixed seats 14, which are respectively fixed to both sides of the hot press plate 10. A connecting piece 15 is fixed to the guide plate 13, and a sliding rod 16 is fixed to the connecting piece 15. The sliding rod 16 is slidably connected to the adjacent fixed seat 14. A rack 17 is fixed to the sliding rod 16. A motor 18 is fixed to the moving plate 9. The motor 18 is electrically connected to the control panel 2. A gear 19 is fixed to the output shaft of the motor 18. The gear 19 meshes with the rack 17.

[0023] Please see Figure 4 and Figure 6 The central structure includes two uprights 20, which are fixed to the movable plate 9 and located on both sides of the hot press plate 10. The uprights 20 are provided with sliding grooves, and two sliders 21 are slidably connected in the sliding grooves of the uprights 20. A telescopic frame 22 is hinged between the two sliders 21. The telescopic part of the telescopic frame 22 is slidably connected to a pressing plate 23, which is located on the upper side of the sliding plate 12. An electric push rod 24 is embedded in the uprights 20. The electric push rod 24 is electrically connected to the control panel 2. The telescopic end of the electric push rod 24 is fixedly connected to the connecting shaft in the middle of the telescopic frame 22 through a connecting block.

[0024] The working principle of this utility model: In use, open the sealing door 5, and then control the motor 18 through the control panel 2. The output shaft of the motor 18 drives the rack 17 to move through the gear 19. The rack 17 drives the sliding rod 16 to move forward along the fixed seat 14. The sliding rod 16 drives the guide plate 13 to move forward through the connector 15. The two guide plates 13 drive the sliding plate 12 to move forward along the hot press plate 10. The sliding plate 12 extends out of the vacuum chamber 4. Then, place the material to be hot-pressed on the sliding plate 12. Then, through the control panel 2, rotate the output shafts of the two motors 18 in opposite directions, so that the sliding plate 12 drives the hot-pressed material to move into the vacuum chamber 4 until the sliding plate 12 returns to its original position.

[0025] Then, close the sealing door 5, and use the vacuum pump to create a vacuum in the vacuum chamber 4. Control the hydraulic cylinder 11 via the control panel 2 to bring the second hot press plate 10 and the first hot press plate 8 closer together. When the second hot press plate 10 and the first hot press plate 8 are about to contact each other, activate the two electric push rods 24 via the control panel 2. The telescopic ends of the electric push rods 24 extend outward, causing the telescopic frame 22 to extend. The extrusion plate 23 slides along the upper side of the sliding plate 12. The two extrusion plates 23 correct the position of the hot-pressed material. After the correction is completed, control the telescopic ends of the two electric push rods 24 to reset, and the two extrusion plates 23 reset to their initial positions without affecting the contact between the second hot press plate 10 and the first hot press plate 8.

[0026] When the hot press plate 10 and the hot press plate 8 have finished hot pressing the material, the extension end of the control hydraulic cylinder 11 drives the moving plate to reset, and then the sealing door 5 is opened. Then the above operation is repeated. The sliding plate 12 drives the hot-pressed material to move outward, so that it is not necessary to reach into the vacuum box 4 to take out the material, thereby preventing burns from the hot press plate 8 and the hot press plate 10.

[0027] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
