A lifting device 9 is fixedly connected to the bottom of the inner wall of box 2. A fixing mechanism 10 is fitted and fixedly connected to the lower mold 3. First slide rails 11 are fixedly connected to both sides of the inner wall of the support frame 1. Electric sliders 12 are slidably connected to the inner wall of the first slide rails 11. A support plate 13 is fixedly connected to one side of the electric slider 12. The fixed ends of first hydraulic rods 14 are fixedly connected to the top diagonal of the support plate 13. The fixed ends of second hydraulic rods 15 are fixedly connected to the top of the support plate 13. The movable end of the first hydraulic rod 14 passes through the support plate 13 and is fixedly connected to a clamping box 16. A positioning device is fitted and fixedly connected to the clamping box 16. Plate 20, a feeding pipe 21 is connected to one side of the clamping box 16, and sliding openings 17 are provided on both sides of the clamping box 16. A clamping mechanism 18 is fixedly connected to one side of the clamping box 16. The movable end of the second hydraulic rod 15 passes through the clamping box 16 and is fixedly connected to the upper mold 19. The clamping mechanism 18 includes a U-shaped frame 181. A dual-axis drive motor 182 is fixedly connected to the inner wall of the U-shaped frame 181. Threaded transmission rods 183 are fixedly connected to the drive shafts at both ends of the dual-axis drive motor 182. The end of the threaded transmission rod 183 away from the dual-axis drive motor 182 is rotatably connected to the inner wall of the U-shaped frame 181. A first sliding block 184 is fitted onto and threadedly connected to 83. An L-shaped connecting rod 185 is fixedly connected to the side of the first sliding block 184 away from the U-shaped frame 181. A first connecting rod 186 is fixedly connected to the end of the L-shaped connecting rod 185 away from the first sliding block 184. A second connecting rod 187 is fixedly connected to the end of the first connecting rod 186 away from the L-shaped connecting rod 185. A clamping plate 188 is fixedly connected to the end of the second connecting rod 187 away from the first connecting rod 186. The U-shaped frame 181 is fixedly connected to one side of the clamping box 16. The side of the clamping plate 188 is slidably connected to the inner wall of the sliding opening 17.

[0018] In use, the clamping box 16 is moved to the top of the housing by activating the electric slider 12. Then, the first hydraulic rod 14 is activated, and the movable end of the first hydraulic rod 14 extends, causing the clamping box 16 to move downwards until it covers the housing and stops moving. Then, the dual-axis drive motor 182 is activated, and the drive shafts at both ends of the dual-axis drive motor 182 rotate, causing the threaded transmission rod 183 to rotate. The rotation of the threaded transmission rod 183 causes the first sliding block 184 to move towards the center of the housing. The movement of the first sliding block 184 causes the L-shaped connecting rod 185 to move. The movement of the L-shaped connecting rod 185 causes the first connecting rod 186 to move. The movement of the first connecting rod 186 causes the second connecting rod 187 to move. The movement of the second connecting rod 187 causes the clamping plate 188 to move until it clamps the housing. The holding plate 188 firmly clamps the box body, and then the electric slider 12 moves the clamping box 16 and the clamped box body to above the lower mold 3. Next, the second hydraulic rod 15 is activated, and the movable end of the second hydraulic rod 15 extends, driving the upper mold 19 to move downward until the box body is moved above the lower mold 3. Then, the dual-axis drive motor 182 is activated in reverse, so that the holding plate 188 releases the box body, allowing the box body to enter the lower mold 3. Then, the second hydraulic rod 15 is activated again, and the second hydraulic rod 15 extends, driving the upper mold 19 to close with the lower mold 3. The foaming thickness above the box body can be controlled by controlling the extension of the second hydraulic rod 15 to meet the needs of different processes. The automated feeding reduces the labor intensity of manual handling, thereby improving work efficiency.

[0019] For the second embodiment, please refer to... Figures 1-7 Based on the first embodiment, the present invention provides a technical solution: the positioning plate 20 includes a first annular fixing plate 201, an annular sealing insert plate 202 is fixedly connected to the bottom of the first annular fixing plate 201, and a threaded hole 203 is opened on the side of the annular sealing insert plate 202. The fixing mechanism 10 includes a second annular fixing plate 101, a positioning groove 102 is opened on the top of the second annular fixing plate 101, and a fixing screw 103 is evenly threaded through and threaded to the side of the second annular fixing plate 101. A fixing handle 104 is fixedly connected to the end of the fixing screw 103 away from the second annular fixing plate 101. The second annular fixing plate 101 is sleeved and fixedly connected to the lower mold 3. The inner wall of the positioning groove 102 is slidably connected to the side of the annular sealing insert plate 202, and the side of the fixing screw 103 is threadedly connected to the inner wall of the threaded hole 203.

[0020] During use, as the upper mold 19 and lower mold 3 are closed, the clamping box 16 moves downward, causing the annular sealing plate 202 to be inserted into the positioning groove 102 to complete the initial positioning. When the annular sealing plate 202 is fully inserted into the positioning groove 102 and the upper mold 19 and lower mold 3 are closed, the fixing handle 104 is rotated. The rotation of the fixing handle 104 causes the fixing screw 103 to rotate, thereby allowing the fixing screw 103 to enter the threaded hole 203. As the fixing handle 104 continues to rotate, when the fixing handle 104 rotates to fit against the side of the second annular fixing plate 101, the operation of firmly fixing the annular sealing plate 202 is completed. This avoids the leakage of foam material after the foaming material expands and overflows, affecting the sealing performance and foaming quality of the mold. It ensures the stability of the mold during the foaming process, effectively prevents the leakage of foam material, and thus improves the overall quality of the product.

[0021] Third embodiment, please refer to Figures 1-9 Based on the second embodiment, the present invention provides a technical solution: the exhaust box 8 includes an annular box body 81, a sealing plate 82 is uniformly and slidably connected through the top of the annular box body 81, a trigger rod 83 is fixedly connected to the top of the sealing plate 82, a first spring 84 is fixedly connected to the bottom of the sealing plate 82, one end of the first spring 84 away from the sealing plate 82 is fixedly connected to the bottom of the inner wall of the annular box body 81, an annular cold water pipe 85 is fixedly connected to the top of the inner wall of the annular box body 81, the side of the annular box body 81 is slidably connected to the inner wall of the annular groove 7, and the bottom of the annular box body 81 is connected to the suction pipe 6.

[0022] During use, when foaming begins inside the mold, gas and heat are generated. As foaming continues, the volume expands, pushing the sealing plate 82 and trigger rod 83 downwards. The downward movement of the trigger rod 83 causes the sealing plate 82 to move downwards, thereby opening the vent at the top of the annular box 81. Simultaneously, the first spring 84 is compressed, causing it to undergo elastic deformation. The interior of the mold and the interior of the annular box 81 are connected, allowing gas to enter the interior of the annular box 81. The gas is then drawn out of the device by the suction pump 5 through the suction pipe 6, thus achieving automatic venting. Meanwhile, the continuously flowing cooling water in the annular cold water pipe 85 absorbs the heat generated by foaming, keeping the internal temperature of the mold within a suitable range and preventing excessive temperature from affecting the foaming quality. At the same time, when the material is removed, the first spring 84 returns to its elastic deformation, and the sealing plate 82 returns to its initial position under the elastic force of the first spring 84, thereby resealing the vent at the top of the annular box 81. This prevents waste caused by overflow when unfoamed foaming material is poured in again, effectively improving the stability of the foaming process and product quality.

[0023] For the fourth embodiment, please refer to [link / reference]. Figures 1-10Based on the third embodiment, the present invention provides a technical solution: the lifting device 9 includes a second slide rail 91, a second sliding block 92 is slidably connected to the inner wall of the slide rail 91, a wedge-shaped base 93 is fixedly connected to the top of the second sliding block 92, a wedge block 94 is slidably connected to the inclined sliding surface of the wedge-shaped base 93, the movable end of a dual-axis hydraulic rod 95 is fixedly connected to the side of the wedge base 93, two sets of wedge-shaped bases 93 are provided and symmetrically distributed on both sides of the dual-axis hydraulic rod 95, a second spring 96 is fixedly connected to the top of the wedge block 94, a lifting rod 97 is fixedly connected to the part of the top of the wedge block 94 located inside the second spring 96, two sets of second slide rails 91 are provided and symmetrically fixedly connected to the bottom of the inner wall of the base box 2, the end of the second spring 96 away from the wedge block 94 is fixedly connected to the bottom of the lower mold 3, and the lifting rod 97 passes through the bottom of the lower mold 3 and is fixedly connected to the bottom of the annular box 81.

[0024] In use, when it is necessary to remove the foamed material from the mold, the dual-axis hydraulic rod 95 is activated. The movable end of the dual-axis hydraulic rod 95 extends, causing the wedge-shaped base 93 to move to both sides. The movement of the wedge base 93 causes the wedge block 94 to slide on its inclined sliding surface. At the same time, the lifting rod 97 passes through the bottom of the lower mold 3 and is fixedly connected to the bottom of the annular groove 7. During the sliding process of the wedge block 94, the second spring 96 is compressed, and the lifting rod 97 moves upward steadily. The upward movement of the lifting rod 97 causes the annular groove 7 to move upward, which in turn causes the material to move upward, thereby lifting the foamed material out of the mold, making it convenient for workers to remove the material and improving work efficiency.

[0025] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.
