Detailed Implementation

[0026] The present application will be further described in detail below with reference to the accompanying drawings.

[0027] Reference Figure 1 and Figure 3 This application discloses a demolding device for a tire inner tube vulcanizing machine, including a lower mold 110, an upper mold 112 which is lifted and lowered on top of the lower mold 110 by a hydraulic component 111, a demolding assembly 150 is provided inside the lower mold 110, and an annular cover 130 is provided on the outer side of the lower mold 110. Multiple air suction holes 131 are provided on the inner side of the annular cover 130 to absorb the heat and gas generated by the vulcanized tire.

[0028] The tire to be vulcanized is placed on top of the lower mold 110, and the upper mold 112 is raised and lowered under the drive of the hydraulic component 111. The lower mold 110 vulcanizes the tire. After vulcanization, air is drawn in through multiple air suction holes 131 inside the annular cover 130. The heat and gas on the tire surface are drawn in through the multiple air suction holes 131 to achieve the purpose of cooling the tire surface. The demolding component 150 facilitates the demolding of the tire.

[0029] Reference Figure 1 - Figure 4 A fixing plate 120 is fixedly installed on the outer side of the annular cover 130. A fan 133 is fixedly installed on the outer side of the fixing plate 120. An air pipe connector 132 is fixedly installed at the suction end of the fan 133. The outer side of the air pipe connector 132 is fixedly installed with the outer side of the annular cover 130. The air pipe connector 132 is connected to multiple air suction holes 131. An air outlet pipe 134 is fixedly installed at the air outlet end of the fan 133. An air washing box 135 is installed at one end of the air outlet pipe 134. Hydraulic components 111 are installed on the outer walls of both sides of the lower mold part 110. An upper mold part 112 is installed at the top of the two hydraulic components 111 relative to the position of the lower mold part 110. An air bladder part 113 is lifted and installed at the center of the injection groove inside the lower mold part 110. A lifting component is installed at the bottom of the demolding assembly 150. The demolding assembly 150 includes a lifting plate 151. A T-shaped component 152 is supported at the center of the lifting plate 151. A sealing ring is rotatably installed on the top of the T-shaped component 152. 154. A conveying component 156 is vertically connected to the top of the sealing ring 154. Gas flows upward through the end of the T-shaped component 152, through the sealing ring 154 and the inside of the conveying component 156, and enters the airbag part 113. An air pump 159 is connected to one side of the end of the T-shaped component 152 through an air supply pipe. A solenoid valve 158 is provided between the air pump 159 and the air supply pipe of the T-shaped component 152 to control the opening and closing of the gas. A drive motor 153 is provided on the side of the lifting plate 151 opposite to the air pump 159. A gear 155 is connected to the top output shaft of the drive motor 153. The gear 155 meshes with the outer side of the gear ring 157. The lifting assembly includes an electric push rod 140. The top of the electric push rod 140 is connected to the bottom of the demolding assembly 150. Sliding rods 141 are symmetrically arranged on both sides of the electric push rod 140. The sliding rods 141 slide vertically through the inside of the lifting plate 151. The ends of the sliding rods 141 are fixedly connected to the inner wall of the lower mold part 110.

[0030] The tire to be vulcanized is placed on top of the lower mold 110, so that the upper mold 112 cooperates with the lower mold 110 to vulcanize the tire. After vulcanization, the air pump 159 is started, and gas passes through the T-shaped part 152 and enters the conveyor 156. Then, the inner wall of the air bladder part 113 is inflated, forming a full elliptical shape. Subsequently, the electric push rod 140 is started, which drives the lifting plate 151 to rise a short distance, during which the tire separates from the lower mold 110. The drive motor 153 drives the gear 155 to rotate, thereby driving the gear ring 157. The rotation causes the toothed ring 157 to drive the airbag part 113 to rotate, which in turn causes the tire to rotate. At the same time, the blower 133 drives the air pipe connector 132 to draw in air, which in turn draws in air through the multiple air intake holes 131 inside the annular cover 130. The heat and gas on the tire surface are drawn in through the multiple air intake holes 131 and enter the air washing box 135 through the air outlet pipe 134 for subsequent exhaust gas treatment. Finally, the air pump 159 is controlled to extract the gas. After the gas disappears, the airbag part 113 will shrink and deflate, thereby achieving the purpose of demolding.

[0031] The drive motor 153 drives the gear 155 to rotate, and the gear 155 drives the sealing ring 154 to rotate, so that the upper airbag part 113 can rotate, making the annular cover 130 more effective at drawing in heat and gas from the tire surface.

[0032] In summary, the demolding device of the tire inner tube vulcanizing machine disclosed in this application, when in use, places the tire to be vulcanized on top of the lower mold 110, so that the upper mold 112 cooperates with the lower mold 110 to vulcanize the tire. After vulcanization, the air pump 159 is started, and gas passes through the T-shaped part 152 and enters the conveyor 156. Then, the inner wall of the air bladder 113 is inflated, becoming a full elliptical shape. Subsequently, the electric push rod 140 is started, driving the lifting plate 151 to rise a short distance, during which the tire and the lower mold 110 are separated. The drive motor 153 drives the gears. Rotation of 155 drives the gear ring 157 to rotate, which in turn drives the airbag part 113 to rotate, causing the airbag part 113 to rotate the tire. Simultaneously, the blower 133 drives the air pipe connector 132 to draw in air, which in turn draws in air through multiple air intake holes 131 inside the annular cover 130. The heat and gas on the tire surface are drawn in through the multiple air intake holes 131 and enter the air washing box 135 through the air outlet pipe 134 for subsequent exhaust gas treatment. Finally, the air pump 159 is controlled to extract the gas. After the gas disappears, the airbag part 113 shrinks and deflates, thereby achieving the purpose of demolding.
