[0015] Working principle: When the mold is opened, the heating mechanism is moved to other positions. Specifically, the hydraulic cylinder is activated to cause the second mold base to slide on the outer wall of the guide rod and drive the upper mold to move downward and slide into the inner wall of the lower mold for injection molding of the material. During the downward movement of the second mold base, the second mold base drives the second rack to move downward and slide on the inner wall of the rectangular groove. When the second rack moves downward, it causes the first gear meshed with it to rotate and drives the first rotating column to rotate inside the U-shaped frame. Furthermore, the first rack meshed with the first gear moves upward. The first rack moves upward to drive the rectangular cover to move upward and slide on the outer wall of the slide rail. Then, the heating plate is driven by the rectangular cover to move to both sides of the upper mold and the lower mold to make the material reach the molten state. When the mold is opened, at this time, the second rack moves upward, so that the first gear rotates in reverse, which causes the first rack to move downward and drives the rectangular cover to move downward and slide on the outer wall of the slide rail, disengaging from the heating state of the upper mold and the lower mold.

[0016] When the mold is opened and reset, the cooling mechanism is pushed to move and continue to contact the inner top wall of the first mold base to cool the lower mold. Specifically, during the downward movement of the second mold base driving the upper mold, the second mold base will drive the second rack to move downward and slide on the inner wall of the rectangular groove and fit with the upper surface of the abutting block. Then, the abutting block drives the hollow frame to move downward. When the hollow frame moves downward, it drives the sliding column to move downward and slide inside the bottom plate and causes the spring to contract under force. Furthermore, the hollow frame and the spiral cooling pipe are disengaged from the fitting state with the inner top wall of the first mold base. When the mold is opened, at this time, the second mold base moves upward, so that the second rack moves upward, causing the abutting block to no longer be stressed. Then, the spring in the contracted state rebounds and resets to push the hollow frame and the spiral cooling pipe to reset, restoring to the fitting state with the inner wall of the first mold base, and then restoring the cooling state of the lower mold.

[0017] The motor is activated to cause its output end to be rotatably connected to the inside of the bottom plate and drive the first fan blade and the second gear to rotate. The rotation of the second gear drives the second rotating column to rotate inside the bottom plate through the third gear. The rotation of the second rotating column drives the second runner to rotate. The rotation of the second runner drives the first runner to rotate through the belt, so that the third rotating column drives the second fan blade to rotate. Through the rotation of the second gear and the second fan blade, the air inside the first mold base forms a convection, providing good air flow conditions for the cooling process. Through the cooperation of the rotation of the first fan blade and the second fan blade and the spiral cooling pipe, the air flow fully contacts the surface of the lower mold and the molded material, accelerating heat transfer and taking away the heat, thereby reducing the temperature of the lower mold and the material.

[0018] The present invention provides a novel high-toughness polyurethane composite material forming device, which has the following beneficial effects: 1. When the present invention closes the mold, the heating mechanism can move to both sides of the upper mold and the lower mold, ensuring that the curing reaction of the material is consistent at each part in the mold, improving the product quality and performance consistency, reducing defects caused by uneven temperature, and when opening the mold, the heating mechanism moves out to avoid unnecessary heating of the upper mold and the lower mold, maintaining the dimensional stability of the formed product and ensuring the dimensional accuracy of the product.

[0019] 2. During the process of the present invention passing through the spiral cooling pipe, a cold air flow is generated in the air-cooling mechanism to exchange heat with the lower mold. The spiral cooling pipe increases the contact area and contact time between the cooling water and the lower mold. When the cooling water flows in the spiral cooling pipe, the path becomes longer and the flow rate is relatively stable, enabling it to absorb the heat dissipated by the lower mold material more fully.

[0020] 3. When the present invention closes the mold, the cooling mechanism disengages from the lower mold, avoiding cooling interference with the filling and curing molding process of the composite material in the lower mold, providing a good temperature and pressure environment for it. When opening the mold, the cooling mechanism fits and can be reset in time to cool the lower mold and then cool the formed product, optimizing the product performance and dimensional accuracy, being able to quickly cool the product, shortening the cooling time, and helping to improve the overall production efficiency.

[0021] 4. Through the mutual cooperation of the rotation of the first fan blade and the second fan blade and the spiral cooling pipe, the present invention enables the air flow to fully contact the surface of the lower mold and the formed material, accelerating heat transfer and taking away the heat, thereby reducing the temperature of the lower mold and the material.

[0026] Specifically, the hydraulic cylinder 4 is activated to cause the second die holder 5 to drive the upper die 6 to move downward and slide on the inner wall of the lower die 7 to achieve mold clamping. Then, the hydraulic cylinder 4 is activated to cause the second die holder 5 to move upward and drive the upper die 6 to slide out from the inner wall of the lower die 7 to achieve mold opening. The guide rod 2 can play a guiding role in the movement of the second die holder 5. The heating mechanism is used to heat the upper die 6 and the lower die 7 when they are clamped together, so that the material reaches a molten state. The moving mechanism is used to move the heating mechanism to both sides of the upper die 6 and the lower die 7 when they are clamped together, and move the heating mechanism to other positions when the mold is opened. The cooling mechanism is used to cool the lower die 7 in cooperation with the air-cooling mechanism. The air-cooling mechanism is used to allow the air flow to fully contact the first die holder 1, accelerate heat transfer, and take away the heat, thereby reducing the temperature of the lower die 7 and the material.

[0027] Please refer to the appendix Figure 1 - appendix Figure 3 , the heating mechanism includes a slide rail 11, the outer wall of the slide rail 11 is fixedly connected to the outer wall of the first die holder 1, a rectangular cover 12 is slidably connected to the outer wall of the slide rail 11, a heating plate 13 is arranged inside the rectangular cover 12, and a temperature controller 14 is arranged on the outer wall of the rectangular cover 12.

[0028] Specifically, the heating mechanism is used to heat the upper die 6 and the lower die 7 when they are clamped together, so that the material reaches a molten state. During the process of clamping the upper die 6 and the lower die 7 together, it will cause the rectangular cover 12 to move upward and slide on the outer wall of the slide rail 11 and slide to both sides of the second die holder 5 and the lower die 7, so that the material in the lower die 7 reaches a molten state. Among them, the slide rail 11 is used to limit the rectangular cover 12, and at the same time, it can also play a guiding role in the movement of the rectangular cover 12.

[0029] Please refer to the appendix Figure 1 - appendix Figure 3 , the moving mechanism includes a second rack 19, the upper surface of the second rack 19 is fixedly connected to the lower surface of the second die holder 5; the moving mechanism also includes a U-shaped frame 18, the lower surface of the U-shaped frame 18 is fixedly connected to the upper surface of the first die holder 1, a first rotating column 17 is fixedly connected inside the U-shaped frame 18, the outer wall of the first rotating column 17 is rotatably connected to the U-shaped frame 18, and the tooth end of the U-shaped frame 18 is meshed with the tooth end of the second rack 19; the moving mechanism also includes a first rack 15, the tooth end of the first rack 15 is meshed with the tooth end of the first gear 16, and the outer wall of the first rack 15 is fixedly connected to the outer wall of the heating plate 13; Specifically, the function of the moving mechanism is to move the heating mechanism to both sides of the upper mold 6 and the lower mold 7 when the upper mold 6 and the lower mold 7 are closed, and move the heating mechanism to other positions when the mold is opened. Specifically, when the hydraulic cylinder 4 is activated, it causes the second mold base 5 to slide on the outer wall of the guide rod 2 and drives the upper mold 6 to move downward and slide into the inner wall of the lower mold 7 for injection molding of the material. During the downward movement of the second mold base 5, the second mold base 5 drives the second rack 19 to move downward and slide on the inner wall of the rectangular groove 9. When the second rack 19 moves downward, it causes the first gear 16 meshed with it to rotate and drives the first rotating column 17 to rotate inside the U-shaped frame 18. As a result, the first rack 15 meshed with the first gear 16 moves upward. The upward movement of the first rack 15 drives the rectangular cover 12 to move upward and slide on the outer wall of the slide rail 11. Then, the heating plate 13 is driven by the rectangular cover 12 to move to both sides of the upper mold 6 and the lower mold 7 to make the material reach the molten state. When the mold is opened, at this time, the second rack 19 moves upward, which causes the first gear 16 to reverse. As a result, the first rack 15 moves downward and drives the rectangular cover 12 to move downward and slide on the outer wall of the slide rail 11, disengaging from the heating state of the upper mold 6 and the lower mold 7. When the mold is closed, the heating mechanism is located on both sides of the upper mold 6 and the lower mold 7, which can heat the upper mold 6 and the lower mold 7 more evenly. During the forming process of the polyurethane composite material, a higher requirement is placed on the temperature uniformity. This can ensure that the curing reaction of the material in each part of the upper mold 6 and the lower mold 7 proceeds evenly, thereby improving the quality and performance consistency of the product and reducing product defects caused by temperature differences, such as local hardness or softness, uneven shrinkage, etc. When the mold is opened, the heating mechanism is removed, which can prevent the upper mold 6 and the lower mold 7 from being continuously heated unnecessarily after being opened, effectively maintaining the dimensional stability of the formed product, thereby ensuring that the product dimensional accuracy meets the requirements and reducing the product rejection rate caused by dimensional deviation. At the same time, when the mold is opened, the heating mechanism is moved away, reducing the influence of high temperature on the operator during the process of taking out the parts and cleaning, improving the safety and comfort of the working environment, and reducing the risk of the operator being scalded.

[0030] Please refer to the attached Figure 1 - attached Figure 4, the cooling mechanism includes a fixing plate 20, the outer wall of the fixing plate 20 is fixedly connected to the outer wall of the first die base 1, the upper surface of the fixing plate 20 is fixedly connected with a water pump 21, the output end of the water pump 21 is fixedly connected with a second conveying pipe 27, the other end of the second conveying pipe 27 is fixedly connected with a hollow frame 25, a spiral cooling pipe 26 is arranged on the inner wall of the hollow frame 25, a blocking block 28 is fixedly connected to the outer wall of the hollow frame 25, the upper surface of the blocking block 28 is in contact with the lower surface of the second rack 19, the upper surface of the hollow frame 25 is in contact with the inner top wall of the first die base 1, and the outer wall of the spiral cooling pipe 26 is in contact with the inner top wall of the first die base 1; the cooling mechanism further includes a refrigerator 23, the outer wall of the refrigerator 23 is fixedly connected to the outer wall of the first die base 1, one end of a first conveying pipe 24 is fixedly connected to the outer wall of the refrigerator 23, the other end of the first conveying pipe 24 is fixedly connected to the outer wall of the hollow frame 25, one end of a connecting pipe 22 is fixedly connected to the outer wall of the refrigerator 23, the other end of the connecting pipe 22 is fixedly connected to the input end of the water pump 21, the outer wall of the second conveying pipe 27 is fixedly connected inside the first die base 1, and the outer wall of the first conveying pipe 24 is fixedly connected inside the first die base 1.

[0031] Specifically, the function of the cooling mechanism is to cool the lower die 7 in cooperation with the air cooling mechanism. When the water pump 21 is started, the cooled water inside the refrigerator 23 is conveyed to the inside of the hollow frame 25 through the connecting pipe 22 and the second conveying pipe 27. During the process of passing through the spiral cooling pipe 26, heat exchange is carried out between the cold air flow generated by the air cooling mechanism and the lower die 7. The spiral cooling pipe 26 increases the contact area and contact time between the cooling water and the lower die 7. When the cooling water flows inside the spiral cooling pipe 26, the path becomes longer and the flow rate is relatively stable, so that the heat dissipated by the material of the lower die 7 can be absorbed more fully.

[0032] Please refer to Appendix Figure 1 , Appendix Figure 5 and Appendix Figure 6 , the reset mechanism includes a sliding column 30, the outer wall of the sliding column 30 is slidably connected inside the bottom plate 29, a spring 31 is slidably connected to the outer wall of the sliding column 30, one end of the spring 31 is fixedly connected to the upper surface of the bottom plate 29, and the other end of the spring 31 is fixedly connected to the lower surface of the hollow frame 25.

[0033] Specifically, the reset mechanism functions to cause the cooling mechanism to disengage from the inner top wall of the first die base 1 when the upper die 6 and the lower die 7 are closed, and to reset during the mold opening process, pushing the cooling mechanism to move and continue to contact the inner top wall of the first die base 1 to cool the lower die 7. Specifically, during the process of the second die base 5 driving the upper die 6 to move downward, the second die base 5 will drive the second rack 19 to move downward and slide on the inner wall of the rectangular groove 9 and fit with the upper surface of the abutting block 28, thereby causing the abutting block 28 to drive the hollow frame 25 to move downward. When the hollow frame 25 moves downward, it drives the sliding column 30 to move downward and slide inside the bottom plate 29, causing the spring 31 to be compressed. As a result, the hollow frame 25 and the spiral cooling pipe 26 are disengaged from the fitting state with the inner top wall of the first die base 1. When the mold is opened, the second die base 5 moves upward at this time, causing the second rack 19 to move upward, so that the abutting block 28 is no longer stressed. As a result, the spring 31 in the contracted state rebounds and resets, pushing the hollow frame 25 and the spiral cooling pipe 26 to reset and return to the fitting state with the inner wall of the first die base 1, thereby restoring the state of cooling the lower die 7. When the mold is closed, the cooling mechanism disengages from the lower die 7, which can avoid cooling interference with the filling and curing process of the composite material in the lower die 7, providing a good temperature and pressure environment for it. When the mold is opened, the fitting can cool the formed product in time, optimize the product performance and dimensional accuracy, can quickly cool the product, shorten the cooling time, and contribute to improving the overall production efficiency.

[0034] Please refer to the attached Figure 2 - attached Figure 6 As shown in the figure, the air-cooling mechanism includes a motor 32. The output end of the motor 32 is rotatably connected inside the bottom plate 29 and fixedly connected with a second gear 33 and a first fan 34. The tooth end of the second gear 33 is meshed with a third gear 35. The inside of the third gear 35 is fixedly connected with a second rotating column 36. The outer wall of the second rotating column 36 is rotatably connected inside the bottom plate 29. The outer wall of the second rotating column 36 is fixedly connected with a second runner 37. A belt 8 is arranged on the outer wall of the second runner 37. The inner wall of the belt 8 is connected with a first runner 10. The air-cooling mechanism further includes a third rotating column 38. The outer wall of the third rotating column 38 is rotatably connected inside the bottom plate 29. The outer wall of the third rotating column 38 is fixedly connected with a second fan 39. The outer wall of the third rotating column 38 is fixedly connected to the inner wall of the first runner 10.

[0035] Specifically, the start of the motor 32 causes its output end to be rotationally connected inside the bottom plate 29 and drives the first fan 34 and the second gear 33 to rotate. The rotation of the second gear 33 drives the second rotating column 36 to rotate inside the bottom plate 29 through the third gear 35. The rotation of the second rotating column 36 drives the second runner 37 to rotate. The rotation of the second runner 37 drives the first runner 10 to rotate through the belt 8, and then the third rotating column 38 drives the second fan 39 to rotate. Through the rotation of the second gear 33 and the second fan 39, the air inside the first mold base 1 forms a convection, providing good air flow conditions for the cooling process. Through the mutual cooperation of the rotation of the first fan 34 and the second fan 39 and the spiral cooling pipe 26, the air flow is fully contacted with the surface of the lower mold 7 and the molding material, accelerating heat transfer and taking away the heat, thereby reducing the temperature of the lower mold 7 and the material.
