Technical Field

[0001] The utility model relates to the technical field of hot presses, in particular to a hot press with a demoulding function. Background Technique

[0002] With the development of economy and the progress of technology, wood-based panels are more and more widely used in people's daily life. Now there are many composite boards and plywoods, which are bonded with glue during the manufacturing process. Then the glued boards are placed between the hot pressing plates of the hot press, and the transmission mechanism drives the distance between the hot pressing plates to decrease, applying pressure to the boards. The functions of the hot pressing plates are, firstly, to pressurize the wet boards to be pressed to remove a certain amount of moisture, and secondly, to heat the wet boards by using the heat circulation channels in the hot pressing plates to dry them to meet the process requirements. Publication No.: CN213830492U discloses a hot press for processing plates with adjustable temperature, including an operation board, a top of the operation board is fixedly connected with an operation frame, a top of the inner cavity of the operation frame is fixedly connected with a hydraulic cylinder, an output end of the hydraulic cylinder is fixedly connected with a mounting plate, a bottom of the mounting plate is fixedly connected with an upper hot pressing plate, and a surface of the operation board is fixedly connected with a lower hot pressing plate that cooperates with the upper hot pressing plate. By the operation board, a PID controller, a PLC controller, a hydraulic cylinder, a first infrared temperature sensor, an upper hot pressing plate, a lower hot pressing plate, a second infrared temperature sensor and heating resistance wires, the device can achieve the function of adjustable temperature, solving the problem that the existing hot presses in the market do not have the function of adjustable temperature, and it is easy to have the phenomenon of too high or too low temperature during the hot pressing process, which affects the processing efficiency and quality, and is not conducive to the operation of users. However, during the use of the above technology, when the hot pressing of the board is completed, the board may adhere to the workbench due to the glue extruded from the board, and the worker cannot remove the board from the workbench and needs to rely on tools, resulting in low work efficiency and affecting the production efficiency.

[0024] Embodiment 1

[0025] Please refer to Figures 1-6 , the present utility model provides a technical solution: a hot press with a demoulding function, including a workbench 1, a support frame 2, and a hot pressing plate 3. The support frame 2 is fixedly connected to the surface of the workbench 1. A cylinder 4 is fixedly connected to the surface of the support frame 2. The output end of the cylinder 4 is fixedly connected to a connecting plate 5. A hot pressing plate 3 is fixedly connected to the surface of the connecting plate 5. A U-shaped bracket 6 is fixedly connected to the lower surface of the workbench 1. A first electric push rod 7 is fixedly connected to the surface of the U-shaped bracket 6. The output end of the first electric push rod 7 is fixedly connected to a support rod 8. Both ends of the support rod 8 are fixedly connected to a top rod 9. The other end of the top rod 9 is fixedly connected to a long rod 10. A groove 14 is formed on the surface of the workbench 1. The long rod 10 is slidably connected to the groove 14. The top rod 9 is slidably connected to the workbench 1. A first sliding groove 25 is formed on the surface of the long rod 10. A pull rod 11 is slidably connected to the inside of the first sliding groove 25. A handle 12 is fixedly connected to the surface of the pull rod 11. Here, it is convenient for workers to take out the plate from between the hot pressing plate 3 and the workbench 1, and it is convenient for workers to carry and move the plate. There are two groups of long rods 10, and the two groups of long rods 10 are symmetrically distributed in the middle of the surface of the workbench 1. Here, it can make the force on the plate when it is separated from the surface of the workbench 1 uniform, and avoid tilting due to uneven force when the plate is lifted. A cylindrical sleeve 13 is sleeved on the surface of the handle 12. The material of the cylindrical sleeve 13 is natural rubber material. Here, it can improve the feel of the worker holding the handle 12, and at the same time can reduce the harm to the human body when the worker accidentally hits the handle 12. A first round hole 22 is formed on the surface of the connecting plate 5. First threaded holes 23 are symmetrically formed in the middle of the surface of the hot pressing plate 3. A bolt 24 is inserted into the inside of the first round hole 22. The bolt 24 is rotatably connected to the inside of the first threaded hole 23. Here, it is convenient to disassemble and install the hot pressing plate 3, and at the same time can complete the rapid replacement of the hot pressing plate 3, and avoid the problem that the hot press cannot continue to be used due to the failure of the hot pressing function of the hot pressing plate 3.

[0026] Embodiment 2

[0027] Please refer to Figures 1-6, on both sides of the middle of the surface of the support frame 2, second round holes 19 are symmetrically opened. A guide rod 20 is slidably connected inside the second round holes 19. At both ends of the upper surface of the hot pressing plate 3, second threaded holes 21 are opened. One end of the guide rod 20 is rotatably connected inside the second threaded holes 21. This can play a role in limiting and guiding the hot pressing plate 3 to prevent the hot pressing plate 3 from shaking when moving up and down. At both ends of the upper surface of the workbench 1, second sliding grooves 15 are opened. On one side surface of the second sliding grooves 15, a second electric push rod 16 is fixedly connected. The output end of the second electric push rod 16 is fixedly connected with a slider 17. The upper end of the slider 17 is fixedly connected with a blocking rod 18. This can clamp and fix the plate to prevent the plate from shaking and displacing during the hot pressing process. At the same time, the offset of the plate can be corrected by the relative movement of the two blocking rods 18, so that the plate can be centered and directly below the hot pressing plate 3.

[0028] Working principle: During use, first place the plate on the surface of the workbench 1, and then start the two second electric push rods 16 at the same time. The output end of the second electric push rod 16 pushes the slider 17 to slide inside the second sliding groove 15. While the slider 17 slides, the blocking rod 18 will move along with the slider 17 and gradually reach both sides of the plate, realizing the clamping and fixing of the plate to prevent the plate from shaking and displacing during the hot pressing process. At the same time, the offset of the plate is corrected by the relative movement of the two blocking rods 18, so that the plate can be centered and directly below the hot pressing plate 3. Then start the cylinder 4. The output end of the cylinder 4 pushes the hot pressing plate 3 to move downward and hot press the plate. At the same time, the guide rod 20 also moves along with the hot pressing plate 3. When the hot pressing work is completed, under the action of the cylinder 4, the hot pressing plate 3 moves away from the plate. Then start the first electric push rod 7. The output end of the first electric push rod 7 pushes the support rod 8 to move upward. At the same time, the ejector rods 9 fixedly connected to both ends of the support rod 8 push the long rod 10 to move upward from inside the groove 14, jacking up the plate from the surface of the workbench 1. Then hold the handle 12 and pull the pull rod 11 outwards. While the pull rod 11 slides outwards inside the first sliding groove 25, the plate is pulled out from between the hot pressing plate 3 and the workbench 1, realizing that when the plate is hot pressed, the plate is jacked up to separate it from the workbench 1, preventing the glue extruded from the plate during the hot pressing process from causing the plate to adhere to the surface of the workbench 1. By setting the pull rod 11, the plate can be quickly pulled out from between the hot pressing plate 3 and the workbench 1, facilitating the worker to carry and move the plate.
