[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0024] Please see Figure 1 - Figure 6This utility model provides a stripping structure for a vulcanizing molding die, including a base plate 1. A stripping assembly 2 is provided on the top of the base plate 1. The stripping assembly 2 includes a lower template 201 forming an annular shape. The lower template 201 is fixedly connected to the top of the base plate 1. A limiting groove 202 is formed on the front of the lower template 201. A limiting block 203 that can slide up and down is slidably connected to the inner wall of the limiting groove 202. An outwardly extending connecting rod 204 is fixedly connected to the front of the limiting block 203. The connecting rod 204 is set perpendicular to the limiting block 203. A support plate 205 is fixedly connected to the front of the lower template 201. The support plate 205 is located below the limiting groove 202. A connecting rod is fixedly connected to the top of the support plate 205. The connecting plate 206 has a movable groove 207 on its top that matches the outer contour of the connecting rod 204. In this embodiment, there are two connecting plates 206, which are spaced apart. A movable shaft 208 is fixedly connected between the two connecting plates 206. A fixing block 209 is movably connected to the side surface of the movable shaft 208. The top of the fixing block 209 is arc-shaped, and a fixing groove 210 matching the connecting rod 204 is provided on one side of the fixing block 209. An adjusting block 211 is fixedly connected to one side of the fixing block 209. An adjusting plate 212 that can slide up and down is also slidably connected in the inner cavity of the lower template 201. The adjusting plate 212 is movably connected to the inner wall of the lower template 201. A damper 213 is fixedly connected to the inner wall of the lower mold plate 201. A spring 214 is sleeved on the side surface of the damper 213. An adjusting plate 212 is fixedly connected to the top of the damper 213. A stripper column 215 is fixedly connected to the top of the adjusting plate 212. A stripper disc 216 is fixedly connected to the top of the stripper column 215. By installing the stripper assembly 2, when the upper mold 12 is pressed into the lower mold 217 during the vulcanization molding production of the material, the stripper disc 216 will be pressed downward, thereby causing the adjusting plate 212 to press the damper 213 and spring 214 at the bottom. At the same time, it will drive the connecting rod 204 on one side of the limit block 203 to move to the bottom. When the connecting rod 204 moves downward, the material will be vulcanized. After contacting the fixing block 209, since the top of the fixing block 209 is an arc-shaped structure, when the fixing block 209 is squeezed, it will rotate on the movable shaft 208 until the connecting rod 204 moves into the fixing groove 210. At this time, the fixing block 209 will move back to its original position, so that the fixing groove 210 can be used to limit the connecting rod 204. After the molded product has cooled down, the adjusting block 211 can be pressed, so that the adjusting plate 212 and the limiting block 203 can move. Under the action of the damper 213 and the spring 214, the stripper disc 216 is pushed upward rapidly, so that the product in the mold hole 218 can be pushed out.

[0025] As one implementation method, such as Figure 2As shown, the lower mold 217 is snapped onto the top of the lower template 201, and the top of the lower mold 217 has a mold hole 218. The stripper disc 216 is movably connected to the inner wall of the mold hole 218.

[0026] As one implementation method, such as Figure 5 and Figure 6 As shown, a cooling assembly 3 is provided on the top of the base plate 1. The cooling assembly 3 includes a support rod 301, which is fixedly connected to the top of the base plate 1. A top plate 302 is fixedly connected to the top of the support rod 301. A water pump 303 is fixedly connected to the top of the top plate 302. One end of the water pump 303 is fixedly connected to a connecting pipe 304. A control valve 305 is fixedly connected to the side surface of the connecting pipe 304. The other end of the connecting pipe 304 is fixedly connected to a cooling tank 306. A water supply pipe 307 is fixedly connected to the top of the water pump 303. The water supply pipe 307 is fixedly connected to the inside of the lower mold 217. A drain pipe 308 is fixedly connected to the other side of the cooling tank 306. The drain pipe 308 is fixedly connected to the inside of the lower mold 217. By installing the cooling assembly 3, after the material is extruded and heated by the upper mold 12, the water in the cooling tank 306 can be transported to the lower mold 217 by the water pump 303. Thus, the cooling speed of the product can be accelerated under the action of the cooling water.

[0027] As one implementation method, such as Figure 6 As shown, the top of the cooling box 306 is provided with a water inlet 309, and a sealing cap 310 is fitted onto the inner wall of the water inlet 309.

[0028] As one implementation method, such as Figure 1 As shown, a control panel 4 is fixedly connected to the front of the cooling box 306, and a display screen 5 is fixedly connected to the front of the control panel 4. By installing the control panel 4, an electrical connection can be made between the control panel 4, the electric push rod 6, and the water pump 303.

[0029] As one implementation method, such as Figure 1 As shown, an electric push rod 6 is fixedly connected to the top of the top plate 302, and an upper template 7 is fixedly connected to the other end of the electric push rod 6. A reinforcing ring 8 is fixedly connected to the top of the upper template 7 and is fixedly connected to the side surface of the electric push rod 6.

[0030] As one implementation method, such as Figure 1 As shown, a connecting block 9 is fixedly connected to one side of the upper template 7. A limiting rod 10 is movably connected inside the connecting block 9. The lower end of the limiting rod 10 is fixedly connected to the top of the base plate 1, and the upper end of the limiting rod 10 is fixedly connected to the bottom of the top plate 302.

[0031] As one implementation method, such as Figure 1As shown, the top of the electric actuator 6 is threaded with a reinforcing bolt 11, which fixes the electric actuator 6 to the top plate 302. The bottom of the upper template 7 is fixedly connected with the upper mold 12.

[0032] The stripping structure of this vulcanizing molding die operates as follows:

[0033] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, during the vulcanization molding process, when the upper mold 12 presses into the lower mold 217, it will press the stripper disc 216 downwards. This causes the adjusting plate 212 to press against the damper 213 and spring 214 at the bottom, simultaneously driving the connecting rod 204 on one side of the limiting block 203 to move to the bottom. When the connecting rod 204 contacts the fixing block 209, because the top of the fixing block 209 has an arc-shaped structure, pressing the fixing block 209 will cause it to rotate on the movable shaft 208 until the connecting rod 204 moves into the fixing groove 210. At this time, the fixing block 209 will move to its original position, so that the fixing groove 210 can limit the connecting rod 204. After the molded product has cooled down, the adjusting block 211 can be pressed, so that the adjusting plate 212 and the limiting block 203 can move. Under the action of the damper 213 and the spring 214, the stripping disc 216 is pushed upward quickly, so that the product in the mold hole 218 can be pushed out. At the same time, the water pump 303 can be used to transport water in the cooling box 306 to the lower mold 217, so that the cooling speed of the product can be accelerated under the action of the cooling water.

[0034] In this invention, by installing a stripping assembly, during the vulcanization molding process, when the upper mold presses into the lower mold, it forces the stripping disc downwards. This causes the adjusting plate to press against the damper and spring at the bottom, simultaneously moving the connecting rod on one side of the limiting block downwards. When the connecting rod contacts the fixed block, the top of the fixed block, being arc-shaped, causes it to rotate on the movable shaft during the pressing process until the connecting rod moves into the fixed groove. At this point, the fixed block returns to its original position, thus using the fixed groove to limit the connecting rod. After the molded product cools, the adjusting block can be pressed, allowing the adjusting plate and the limiting block to move. Under the force of the damper and spring, the stripping disc is quickly pushed upwards, ejecting the product from the mold hole and completing the stripping process. This avoids material being difficult to demold, which would affect production efficiency and improves the practicality of the device.

[0035] By installing a cooling component, after the material is extruded and heated in the upper mold, a water pump can be used to transport water from the cooling tank to the lower mold. This cooling water accelerates the cooling speed of the product, thereby improving production efficiency and enhancing the practicality of the device.
