Detailed implementation manners

[0022] The present utility model will be further described below with reference to the accompanying drawings:

[0023] As Figures 1-6 shown, this embodiment provides a rubber vulcanizing machine for automatic sheet discharging, including an equipment bottom plate 1, guide posts 2 and a vulcanization heating seat 3. The guide posts 2 are fixedly installed on both sides of the top of the equipment bottom plate 1, and the vulcanization heating seat 3 is slidably installed on the guide posts 2. Hydraulic telescopic rods 4 are fixedly installed on both sides of the top of the equipment bottom plate 1, and one end of each hydraulic telescopic rod 4 is connected to the bottom of the vulcanization heating seat 3. A U-shaped mounting plate 5 is fixedly installed on the top of the equipment bottom plate 1. A strip-shaped chute 6 is provided on the inner side wall of the U-shaped mounting plate 5, and a sliding block 7 is slidably clamped in the strip-shaped chute 6. Since the sliding block 7 is fixedly connected to the lower die base 8, the lower die base 8 can slide in the strip-shaped chute 6 through the sliding block 7. The lower die base 8 is installed on the outer side wall of the sliding block 7, and an upper die base 9 is provided on the top of the lower die base 8. Sliding columns 10 are installed at the four corners of the bottom of the upper die base 9, through holes are provided at the four corners of the lower die base 8, a discharging assembly 11 is provided at the bottom of the lower die base 8, a lifting assembly 12 is provided on the top of the equipment bottom plate 1, linkage rods 13 are installed on the outer side walls on both sides of the upper die base 9, and an upper die opening and closing assembly 14 is provided on the top of both ends of the U-shaped mounting plate 5.

[0024] One end of the sliding column 10 passes through the through hole. Under the action of the through hole, the phenomenon of offset can be prevented when the sliding column 10 and the upper die base 9 are displaced.

[0025] An electric telescopic rod 15 is fixedly installed on the outer side wall of the U-shaped mounting plate 5. One end of the electric telescopic rod 15 is fixedly connected to the outer side wall of the lower die base 8. After the electric telescopic rod 15 works, it can drive the lower die base 8 to displace. Since the upper die base 9 is arranged on the lower die base 8 through the sliding column 10, when the lower die base 8 displaces, it can drive the upper die base 9 to displace synchronously.

[0026] The discharging assembly 11 includes a circular ejector rod 1101. A circular hole is provided on the lower die base 8. The circular ejector rod 1101 is arranged in the circular hole. A connecting plate 1102 is installed at the bottom of the circular ejector rod 1101. A return spring 1103 is fixedly installed at the top of the connecting plate 1102. One end of the return spring 1103 is connected to the bottom of the lower die base 8. Triangular plates 1104 are symmetrically installed at the bottom of the connecting plate 1102. When the triangular plates 1104 do not contact the rotating wheels 1202, under the action of the return spring 1103, the connecting plate 1102, the triangular plates 1104 and the circular ejector rod 1101 can be reset to their original positions.

[0027] The jacking assembly 12 includes a U-shaped mounting bracket 1201. The U-shaped mounting bracket 1201 is fixedly installed on both sides of the top of the equipment bottom plate 1. A rotating wheel 1202 is rotatably installed on the U-shaped mounting bracket 1201. After the triangular plates 1104 contact the rotating wheels 1202, the triangular plates 1104 can displace on the rotating wheels 1202.

[0028] The upper die opening and closing assembly 14 includes an inclined rod 1401. The inclined rod 1401 is fixedly installed on the top of both ends of the U-shaped mounting plate 5. The linkage rod 13 is located above the inclined rod 1401. A strengthening support rod 1402 is installed on the outer side wall of the inclined rod 1401. One end of the strengthening support rod 1402 is fixedly connected to the U-shaped mounting plate 5. When the linkage rod 13 displaces on the inclined rod 1401, the height of the linkage rod 13 will change. Therefore, when the height of the linkage rod 13 increases, it can drive the upper die base 9 and the sliding column 10 to rise. If the linkage rod 13 displaces in the opposite direction, the sliding column 10 and the upper die base 9 can be lowered.

[0029] When the utility model is in use, the user can first pull the upper die holder 9 upward. When the upper die holder 9 is pulled upward, the sliding column 10 can be driven to rise. After that, the user can place the rubber product into the lower die holder 8. After the placement is completed, the user can make the electric telescopic rod 15 work to drive the lower die holder 8 to displace towards the vulcanization heating seat 3, thereby driving the upper die holder 9 to displace. When the lower die holder 8 displaces, the sliding block 7 can slide in the strip-shaped chute 6 until the lower die holder 8 and the lower die holder 8 displace to the bottom of the vulcanization heating seat 3. Then the user can make the hydraulic telescopic rod 4 work to drive the vulcanization heating seat 3 to descend on the guide post 2 until the vulcanization heating seat 3 is attached to the upper die holder 9. The vulcanization heating seat 3 can vulcanize the rubber product in the upper die holder 9 and the lower die holder 8. After the rubber product is vulcanized, the user drives the upper die holder 9 and the lower die holder 8 to move to the side away from the vulcanization heating seat 3 again through the electric telescopic rod 15. When the upper die holder 9 and the lower die holder 8 move, the linkage rod 13 on the upper die holder 9 moves on the inclined rod 1401. When the linkage rod 13 continues to move, the linkage rod 13 can drive the upper die holder 9 and the sliding column 10 to rise. At this time, the triangular plate 1104 at the bottom of the lower die holder 8 can move on the pulley. When the triangular plate 1104 continues to move, it can drive the connecting plate 1102 and the circular ejector rod 1101 to rise, so that the circular ejector rod 1101 can eject the rubber product in the lower die holder 8, achieving the purpose of automatic discharging, and the practicability is strong.
