Description

Technical Field

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

[0002] A hot press forming machine is a piece of equipment used for processing materials such as plastics and rubber. It mainly compresses and shapes materials by heating and pressurizing. Its main components include a press, a heating system, and a control system. The press provides the necessary pressure, the heating system is responsible for heating the material, and the control system is responsible for controlling the entire heating and pressing process.

[0003] A patent, CN210387039U, discloses a hot pressing forming machine for die-casting mid-plates of mobile phones. The machine includes a heating chamber with multiple guide rods fixedly connected to its upper sidewall. The ends of the guide rods away from the heating chamber are fixedly connected to the same mounting plate. A telescopic cylinder is fixedly connected to the upper sidewall of the mounting plate, and a through hole is provided on the lower sidewall. The output shaft of the telescopic cylinder passes through the mounting plate via the through hole. A pressure plate seat is fixedly connected to the output shaft of the telescopic cylinder. Multiple guide holes corresponding to the guide rods are provided on the upper sidewall of the pressure plate seat. This invention reduces the wear rate of the guide rods and pressure plate seat, improves the service life of the hot pressing forming machine, and allows adjustment of the machine's height according to the operator's height, effectively improving the user comfort.

[0004] However, in the existing technology, the workpiece is generally placed and picked up manually during hot pressing. Since the pressure plate is located directly below the pressure plate, and the surface temperature of the pressure plate is high after use, there is a risk of burns when the user picks up the workpiece, which poses a certain danger.

[0005] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

[0006] The purpose of this utility model is to provide a hot pressing shaping machine that can effectively solve the above-mentioned technical problems.

[0007] To achieve the purpose of this utility model, the following technical solution is adopted:

[0008] A hot press shaping machine includes: a base, a hydraulic cylinder fixedly mounted on the base, a hot press assembly fixedly mounted on the output end of the hydraulic cylinder, a hot press platform slidably mounted on the base, a push assembly for easy handling of the shaped workpiece, and a cooling assembly for accelerating heat dissipation from the surface of the shaped workpiece.

[0009] The pushing component includes: a first rack fixedly mounted on the hot pressing component, a gear shaft meshing with the first rack, a U-shaped frame rotatably connected to the gear shaft, with the bottom of the U-shaped frame fixedly mounted on the surface of the base, a gear fixedly mounted on the gear shaft, and a second rack meshing with the gear, with one end of the second rack fixedly mounted on the surface of the hot pressing platform.

[0010] Furthermore, guide blocks are slidably mounted on the surfaces of both the first and second racks, and one side of the guide block is fixedly mounted on the surface of the U-shaped frame.

[0011] Furthermore, the surface of the base is provided with a through groove, and the through groove is located directly below the adjacent first rack.

[0012] Furthermore, the cooling assembly includes: a fixing member fixedly mounted on the base, a movable member slidably mounted on the fixing member, and the movable member being fixedly connected to the surface of the hot pressing platform, and an air guide member communicating with the movable member.

[0013] Furthermore, several air blowing heads are fixedly installed at equal intervals on the surface of the air guide.

[0014] Compared with the prior art, the present invention has the following advantages: When the workpiece is hot-pressed and shaped, with the cooperation of the pushing component, the hot-pressing component and the hot-pressing platform, when the hot-pressing component moves down, the hot-pressing platform automatically moves to directly below the hot-pressing component to hot-press and shape the workpiece. When the hot-pressing component moves up, the hot-pressing platform automatically moves from below the hot-pressing component to the workpiece pick-up and drop area, preventing the hot-pressed and shaped workpiece from being located below the hot-pressing component. Also, because the surface temperature of the hot-pressing component is high, there is a risk of burns when the user picks up the workpiece. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0023] like Figures 1 to 4 As shown, the present invention provides a hot pressing shaping machine, comprising: a base 1, a hydraulic cylinder 2 fixedly mounted on the base 1, a hot pressing assembly 3 fixedly mounted on the output end of the hydraulic cylinder 2, a hot pressing platform 4 slidably mounted on the base 1, a pushing assembly 5 for facilitating the handling of the shaped workpiece, and a cooling assembly 6 for accelerating heat dissipation from the surface of the shaped workpiece.

[0024] It should be noted that the hot pressing assembly includes a heating system, a control system, and a hot pressing plate. The heating system is responsible for heating the material, while the control system is responsible for controlling the entire heating and pressing process. This is existing technology and will not be elaborated further.

[0025] The pushing component 5 includes: a first rack 501 fixedly mounted on the hot pressing component 3; a gear shaft 502 meshing with the first rack 501; a U-shaped frame 503 rotatably connected to the gear shaft 502, with the bottom of the U-shaped frame 503 fixedly mounted on the surface of the base 1; a gear 504 fixedly mounted on the gear shaft 502; and a second rack 505 meshing with the gear 504, with one end of the second rack 505 fixedly mounted on the surface of the hot pressing platform 4.

[0026] When hot-pressing the workpiece, the workpiece is first placed on the hot-pressing platform 4 in the workpiece handling area. The hydraulic cylinder 2 is then activated, pushing the hot-pressing assembly 3 downwards from its output end. At this time, the two symmetrical first racks 501 at the bottom of the hot-pressing assembly 3 move downwards and mesh with the gear shaft 502, causing the gear shaft 502 to rotate. Simultaneously, the gear 504 fixed to the surface of the gear shaft 502 meshes with the second rack 505, causing the second rack 505 to pull the hot-pressing platform 4 downwards from the hot-pressing assembly 3. After the hot-pressing assembly 3 has moved into position, the second rack 505 moves the hot-pressing platform 4 directly below the hot-pressing assembly 3. After the workpiece is shaped, the output end of the hydraulic cylinder 2 drives the hot pressing assembly 3 to move upward. At this time, the first rack 501 meshes with the gear shaft 502 again, and the gear shaft 502 flips, so that the U-shaped frame 503 fixed on the gear shaft 502 meshes with the second rack 505, thereby causing the second rack 505 to push the hot pressing platform 4 from below the hot pressing assembly 3 to the workpiece pick-up and drop area. On the one hand, it realizes the automatic pushing and pushing of the workpiece, and on the other hand, it prevents the workpiece after hot pressing from being located below the hot pressing assembly 3. Since the surface temperature of the hot pressing assembly 3 is high, there is a risk of burns when the user picks up the workpiece.

[0027] It should be added that guide blocks are slidably mounted on the surfaces of both the first rack 501 and the second rack 505, and one side of the guide block is fixedly mounted on the surface of the U-shaped frame 503. By setting the guide blocks, the stability of the movement of the first rack 501 and the second rack 505 is improved during the movement.

[0028] It should be noted that the surface of the base 1 is provided with a through groove, and the through groove is located directly below the adjacent first rack 501. By setting the through groove, the first rack 501 is prevented from colliding with the surface of the base 1 during downward movement, thus affecting its use.

[0029] The cooling assembly 6 includes: a fixing member 601 fixedly installed on the base 1, a movable member 602 slidably installed on the fixing member 601, and the movable member 602 is fixedly connected to the surface of the hot pressing platform 4, and an air guide member 603 is connected to the movable member 602.

[0030] As a further extension of this application, after hot pressing and shaping, the surface temperature of the workpiece is high, and it is necessary to wait for the surface temperature of the workpiece to drop before it can be removed or placed, while natural cooling efficiency is low.

[0031] Therefore, when the second rack 505 moves the hot pressing platform 4 to the workpiece pick-up and drop area, the fixed part 601 squeezes the air inside the moving part 602, so that the air is blown onto the surface of the workpiece through the air guide 603, thereby accelerating the air flow around the workpiece and further accelerating the heat dissipation of the workpiece.

[0032] It should be added that several air blowing heads are fixedly installed at equal intervals on the surface of the air guide 603. By setting several air blowing heads, air can be blown evenly on the surface of the workpiece after hot pressing and shaping, thereby accelerating the air flow on the surface of the workpiece and improving the heat dissipation efficiency.

[0033] Working Principle: Upon power connection, during hot pressing of the workpiece, the workpiece is first placed on the hot pressing platform 4 in the workpiece placement area. Hydraulic cylinder 2 is activated, pushing the hot pressing assembly 3 downwards from its output end. At this time, the two symmetrical first racks 501 at the bottom of the hot pressing assembly 3 move downwards and mesh with the gear shaft 502, causing the gear shaft 502 to rotate. Simultaneously, the gear 504 fixed to the surface of the gear shaft 502 meshes with the second rack 505, causing the second rack 505 to pull the hot pressing platform 4 downwards from the hot pressing assembly 3. After the hot pressing assembly 3 has moved into position, the second rack 505 moves the hot pressing platform 4 directly below the hot pressing assembly 3 to press the workpiece. After the workpiece is shaped, the output end of the hydraulic cylinder 2 drives the hot pressing assembly 3 to move upward. At this time, the first rack 501 meshes with the gear shaft 502 again, and the gear shaft 502 flips, so that the U-shaped frame 503 fixed on the gear shaft 502 meshes with the second rack 505, thereby causing the second rack 505 to push the hot pressing platform 4 from below the hot pressing assembly 3 to the workpiece pick-up and drop area. When the second rack 505 drives the hot pressing platform 4 to move to the workpiece pick-up and drop area, the fixed part 601 squeezes the air inside the moving part 602, so that the air is blown onto the surface of the workpiece through the air guide 603 to accelerate the air flow around the workpiece, thereby accelerating the heat dissipation of the workpiece.

[0034] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art.
