[0033] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0034] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0035] like Figure 1 , 2 As shown in Figures 3 and 4, this application provides a frame-type hot-press rubber molding machine with waste heat recycling capability, including a device body 1. The device body 1 has four sets of guide columns 15 fixedly connected inside. The device body 1 has a movable plate 10 inside, which is sleeved on the outside of the four sets of guide columns 15. A storage compartment 25 is opened on one side inside the device body 1. The storage compartment 25 has a transmission component inside, which is used to drive the cutting of product scraps. The transmission component includes a rotating shaft 20 rotatably connected to both sides inside the storage compartment 25.

[0036] A cutting plate 16 is fixedly connected to the outside of the rotating shaft 20, and multiple sets of cutting blades are installed on one side of the cutting plate 16;

[0037] Gear 19 is fixedly connected to one end of the outer side of the rotating shaft 20;

[0038] A second sliding groove 24 is provided at the bottom of the storage compartment 25. A matching rack 18 is slidably connected inside the second sliding groove 24. The bottom of the front surface of the rack 18 meshes with the gear 19.

[0039] A connecting plate 17 is fixedly connected to the top of the front surface of the rack 18, and one end of the connecting plate 17 is fixedly connected to one end of the movable plate 10.

[0040] The front surface of the rack 18 is provided with a first sliding groove 21, and a matching slider 22 is slidably connected inside the first sliding groove 21. The front surface of the slider 22 is fixedly connected with a limiting tooth plate 23 that matches the gear 19.

[0041] In this embodiment, when the hot pressing is completed, the control moving plate 10 moves upward, and the connecting plate 17 moves synchronously, causing the moving template 4 to separate from the fixed template 3. After the moving plate 10 moves upward a certain distance, the rack 18 will begin to mesh with the gear 19. The rotation of the gear 19 will synchronously cause the rotating shaft 20 to rotate, thereby causing the cutting plate 16 to flip to cut the scraps of the molded product. When the device needs to be hot pressed again, the control moving plate 10 moves downward, causing the cutting plate 16 to reset. After the rack 18 moves downward a certain distance, the limiting tooth plate 23 will begin to lock the gear 19 and limit its position. As the moving plate 10 continues to move downward, the slider 22 will move in the first sliding groove 21. Due to the gravity of the slider 22, the limiting tooth plate 23 will lock the gear 19 and limit its position at all times during the continuous movement of the moving plate 10. This design can realize convenient cutting of scraps of the molded product after hot pressing, thereby reducing manual labor.

[0042] like Figure 1 , 2 As shown in Figure 5, a hydraulic cylinder 12 is installed on the top of the main body 1 of the device. The output end of the hydraulic cylinder 12 is fixedly connected to the top of the moving plate 10. A control box 2 is fixedly connected to one side of the main body 1 of the device. The control box 2 is electrically connected to the hydraulic cylinder 12.

[0043] The bottom of the movable plate 10 and the bottom of the device body 1 are both fixedly connected to heating plates 11. The bottom of one set of heating plates 11 is fixedly connected to a movable template 4, and the top of the other set of heating plates 11 is fixedly connected to a fixed template 3. Cooling water channels 28 are opened inside both the movable template 4 and the fixed template 3.

[0044] In this embodiment, the user controls the extension and retraction of the output end of the hydraulic cylinder 12 through the control box 2, thereby controlling the movement of the moving plate 10. During hot pressing, the device heats the fixed platen 3 and the moving platen 4 by activating two sets of electric heating plates 11, thereby indirectly heating the rubber raw material.

[0045] like Figure 1 , 2 As shown in Figures 5, 6, and 7, a second communicating shell 27 connected to the cooling water channel 28 is fixedly connected to one side of the moving template 4, and a first communicating shell 26 connected to the cooling water channel 28 is fixedly connected to one side of the fixed template 3.

[0046] The bottom of the second connecting shell 27 is fixedly connected to a connecting shell 32 that communicates with it. A spring 30 is installed at the bottom of the inner part of the connecting shell 32. A sealing plate 31 that matches the inner cavity of the connecting shell 32 is fixedly connected to the end of the spring 30. An insertion hole 29 is opened at the bottom of the connecting shell 32. An insertion shell 34 that communicates with the top of the first connecting shell 26 is fixedly connected to it. The insertion shell 34 matches the insertion hole 29. Water inlet holes 33 that communicate with the inner cavity of the insertion shell 34 are opened on both sides of the insertion shell 34.

[0047] A second water pipe 8 connected to the cooling water channel 28 is fixedly connected to the other side of the movable template 4, and a third water pipe 9 connected to the cooling water channel 28 is fixedly connected to the other side of the fixed template 3.

[0048] A water tank 5 is fixedly connected to one side of the bottom of the main body 1 of the device. A transport pump 6 is installed on one side of the water tank 5. A preheating box 13 is fixedly connected to one side of the main body 1 of the device. A raw material barrel 14 is slidably connected to the top of the preheating box 13. The end of the second water pipe 8 is fixedly connected to the top of the preheating box 13 and is in communication with it. The end of the third water pipe 9 is fixedly connected to one side of the water tank 5 and is in communication with it. One end of the transport pump 6 is fixedly connected to a first water pipe 7 that is in communication with it. The end of the first water pipe 7 is fixedly connected to the bottom side of the preheating box 13 and is in communication with it.

[0049] In this embodiment, when the fixed template 3 and the moving template 4 are closed, the insert shell 34 on the first connecting shell 26 will be inserted into the connecting shell 32 at the bottom of the second connecting shell 27 through the insert hole 29. At the same time, the spring 30 will extend, so that the sealing plate 31 will no longer block the inner cavity of the connecting shell 32, thereby connecting the cooling water channel 28 inside the fixed template 3 and the moving template 4. The water tank 5 will be supplied with cooling water through the third water pipe 9 to the fixed template 3. After passing through the moving template 4, the heated cooling water will be transported to the preheating box 13 through the second water pipe 8, so that the heated cooling water will preheat the raw material in the raw material barrel 14, thereby reducing the heat required when hot pressing the rubber raw material. The preheated cooling water will be transported back to the water tank 5 through the first water pipe 7. The entire water circulation process is powered by the transport pump 6. When the fixed template 3 and the moving template 4 are separated, the spring 30 will reset, so that the sealing plate 31 will block the inner cavity of the connecting shell 32 again to avoid water leakage. This design can realize the water circulation and waste heat recycling of the device.

[0050] Working principle: After the hot pressing is completed, when the control moving plate 10 moves upward, the connecting plate 17 will move synchronously, causing the moving template 4 to separate from the fixed template 3. After the moving plate 10 moves upward a certain distance, the rack 18 will begin to mesh with the gear 19. The rotation of the gear 19 will synchronously cause the rotating shaft 20 to rotate, thereby causing the cutting plate 16 to flip to cut the scraps of the shaped product. When the device needs to be hot pressed again, the control moving plate 10 moves downward, causing the cutting plate 16 to reset. When the rack 18 moves downward... After a certain distance, the limiting tooth plate 23 will begin to lock the gear 19 and limit its movement. As the moving plate 10 continues to move downward, the slider 22 will move in the first sliding groove 21. When the fixed template 3 and the moving template 4 are closed, the insert shell 34 on the first connecting shell 26 will be inserted into the connecting shell 32 at the bottom of the second connecting shell 27 through the insert hole 29. At the same time, the spring 30 will extend, so that the sealing plate 31 will no longer block the inner cavity of the connecting shell 32, thereby connecting the cooling water channel 28 inside the fixed template 3 and the moving template 4.

[0051] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
