Description

Technical Field

[0001] The utility model relates to the technical field of rubber tire processing equipment, in particular to a rubber tire rapid thermoforming machine. Background Art

[0002] Rubber tires are circular elastic rubber products that roll on the ground and are installed on various vehicles or machines. They are usually installed on metal rims, can support the vehicle body, buffer external impacts, achieve contact with the road surface and ensure the driving performance of the vehicle. Rubber tires usually require the use of special hot forming equipment during the vulcanization process.

[0003] Before forming a rubber tire, hot melt rubber needs to be added into the mold and pressurized. As the upper mold squeezes the lower mold, rubber will seep out from the mold closing position. In addition, the existing device lacks an integrated structure that can remove the seeped rubber, which makes it easy for excess material to adhere to the molded rubber tire, thereby reducing the quality of the finished rubber tire. For this reason, we provide a rubber tire rapid thermoforming machine. Utility Model Content

It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0024] Embodiment 1:

[0025] Please combine Figure 1-3 A rubber tire rapid thermoforming machine according to this embodiment includes:

[0026] A processing table 1, a lower mold 2 is fixedly connected to the center of the top of the processing table 1, an upper mold 3 is arranged above the lower mold 2, a counterweight 4 is symmetrically fixedly connected to the top of the upper mold 3, a bracket is fixedly connected to the processing table 1, a hydraulic cylinder 5 is fixedly connected to the top of the bracket, the centers of the lower mold 2 and the upper mold 3 are on the same vertical line, which can ensure the accurate mold closing between the upper mold 3 and the lower mold 2;

[0027] The overflow glue removal component includes a connecting plate 101, the top of the connecting plate 101 is fixedly connected to the telescopic end of the hydraulic cylinder 5, the bottom of the connecting plate 101 is rotatably connected to a hollow tube 102, the inside of the hollow tube 102 is movably connected to a vertical rod 103, and the bottom end of the vertical rod 103 extends to the outside of the hollow tube 102, the outer fixed sleeve of the hollow tube 102 is provided with a connecting piece 104, the outer movable sleeve of the vertical rod 103 is provided with a connecting piece 2 105, and a connecting frame 106 is provided on the upper side of the processing table 1, and the connecting frame 106 is slidably connected to the connecting piece 104 and fixed to the connecting piece 2 105 Connection, a scraper 107 is fixedly connected to the connecting frame 106, and after the mold is closed, the scraper 107 contacts the edges of the upper mold 3 and the lower mold 2 at the same time, and limiting rings 111 are arranged on both sides of the connecting piece 105, and the limiting rings 111 are fixedly connected to the vertical rod 103, which can prevent the connecting piece 105 from vertically sliding outside the vertical rod 103, and the top of the connecting frame 106 is fixedly connected to the limiting plate, which can prevent the connecting frame 106 from detaching from the connecting piece 1 104, and the top of the vertical rod 103 is also fixedly connected to an anti-detachment ring 112, which can prevent the vertical rod 103 from detaching from the hollow tube 102.

[0028] The overflow glue removal kit also includes:

[0029] The T-shaped connector 108 is fixedly connected to the top center of the vertical rod 103, and both ends of the T-shaped connector 108 are movably connected with balls 109. The inner wall of the hollow tube 102 is provided with a spiral groove 110 corresponding to the position of the ball 109.

[0030] The implementation principle of a rubber tire rapid thermoforming machine in the embodiment of the present application is as follows: first, hot melt rubber is added into the lower mold 2, and then the hydraulic cylinder 5 is started to drive the upper mold 3 to move vertically downward. When the upper mold 3 contacts the lower mold 2, the weight of the counterweight block 4 is used to extrude and mold the hot melt rubber. The counterweight block 4 can improve the uniformity of the pressure applied by the upper mold 3 to the lower mold 2, thereby ensuring the molding quality of the rubber tire, and the counterweight block 4 can be replaced according to the pressure required during molding, thereby improving the application range of the device.

The hollow tube 102 rotates, and the rotation of the connecting piece 104 drives the connecting piece 104 to rotate. The movable cooperation between the connecting piece 105 and the vertical rod 103 and the fixed connection between the connecting piece 105 and the connecting frame 106 make the connecting piece 104 drive the connecting frame 106 to rotate. The rotation of the connecting frame 106 drives the scraper 107 to rotate, so that the excess glue overflowing from the mold closing position of the upper mold 3 and the lower mold 2 can be scraped off, thereby effectively avoiding the problem of reducing the quality of the finished product of the rubber tire due to the difficulty in removing the rubber seeping out during processing. At the same time, the sliding cooperation between the connecting frame 106 and the connecting piece 104 is utilized, so that the connecting frame 106 will not affect the downward movement of the hollow tube 102 when rotating. Finally, the hydraulic cylinder 5 is started to drive the upper mold 3 to reset and take out the molded rubber tire.
