[0023] See also Figure 1 , 2 6. A support assembly 2 is provided at the bottom of the lower mold 101, and the support assembly 2 includes a support seat 201 fixed on the bottom of the lower mold 101, a bottom plate 202 is fixedly connected to the bottom of the support seat 201, and a plurality of support columns 203 are fixedly connected to the top of the bottom plate 202. By providing support seats 201 at both ends and the middle part of the bottom plate 202, the two ends and the middle part of the lower mold 101 can be supported, and a plurality of support columns 203 are fixedly connected to the top of the bottom plate 202, so that the support columns 203 evenly support the bottom of the lower mold 101, so that the support columns 203 support the lower mold 101 more evenly, thereby avoiding damage caused by uneven force on the bottom of the lower mold 101, thereby effectively keeping the lower mold 101 level.
[0024] See also Figure 6 , 7 The top of the support column 203 fits with the bottom of the lower mold 101, and the first fixing hole 204 is opened inside the bottom plate 202 and the support column 203. The outer wall of the movable plate 306 is penetrated by a sleeve hole 311. By opening the first fixing hole 204 at the bottom of the support column 203 and the lower mold 101, high-strength bolts are installed and fixed to the lower mold 101 from the bottom of the bottom plate 202 through the first fixing hole 204, so that the lower mold 101 is fixed to the top of the support column 203, which can effectively enable the support column 203 to support the lower mold 101, and the outer wall of the movable plate 306 is opened with a sleeve hole 311 compatible with the support column 203, so that the movable plate 306 slides on the outer wall of the support column 203 through the sleeve hole 311 when moving up and down, thereby preventing the support column 203 from affecting the movement of the movable plate 306.
[0025] See also Figure 2 , 7A second mounting groove 6 is provided at the top of the movable plate 306, and a limiting rod 4 is inserted into the movable plate 306 through the second mounting groove 6. A sliding groove 5 adapted to the limiting rod 4 is provided on the inner side wall of the lower mold 101. The second mounting groove 6 provided at the top of the movable plate 306 is adapted to the bottom of the limiting rod 4, so that the limiting rod 4 can be inserted into the second mounting groove 6, and the limiting rod 4 can be fixed by bolts. The sliding groove 5 provided inside the lower mold 101 is adapted to the limiting rod 4, so that the limiting rod 4 can be inserted into the sliding groove 5, and then the movable plate 306 and the lower mold 101 can be limited to avoid the movable plate 306 from being offset, so that the movable plate 306 can be stably moved, and then the rubber protective device 9 can be effectively demolded.
[0026] See also Figure 1 , 5 6. A heating chamber 7 is opened inside the lower mold 101, and a cover plate 8 is fixedly connected to the outer side wall of the lower mold 101. By opening the heating chamber 7 inside the lower mold 101 and connecting high-temperature steam inside the heating chamber 7, the high-temperature steam heats the inside of the lower mold 101 inside the heating chamber 7, so that the rubber material inside the molding groove 106 can be melted, thereby forming a rubber protective device 9 inside the molding groove 106. The heating chamber 7 can be shielded by the cover plate 8 to prevent leakage of high-temperature steam, so that the high-temperature steam can effectively heat the lower mold 101 inside the heating chamber 7, which can accelerate the melting of the rubber material and thereby improve the manufacturing speed of the rubber protective device 9.
[0027] Working principle: See also Figure 1-7 When the device is in use, the support seat 201 and the support column 203 are fixedly connected to the bottom of the lower mold 101, so that the support seat 201 and the support column 203 can evenly support the bottom of the lower mold 101 to avoid uneven force on the lower mold 101. The upper mold 102 is driven upward by the press to put the rubber into the molding groove 106, and then the upper mold 102 is squeezed on the top of the lower mold 101 by the press, and hot steam is passed into the heating chamber 7. One end of the heating chamber 7 is fixed by the cover plate 8 to avoid leakage of hot steam, so that the rubber is heated under high temperature and high pressure. Under the action, the rubber melts and forms a rubber protective device 9 inside the molding groove 106. After the rubber protective device 9 is made, the upper mold 102 is driven by the press to move upward and separate from the lower mold 101. The hydraulic cylinder 304 fixed on the outer wall of the lower mold 101 drives the movable plate 306 to move on the outer wall of the support column 203, so that the movable plate 306 drives the ejector rod 309 to be ejected inside the plug pin 103, so that the rubber protective device 9 formed inside the molding groove 106 can be ejected under the drive of the ejector rod 309, so that the rubber protective device 9 can be quickly demolded.
