Description

Technical Field

[0001] This utility model relates to the technical field of rubber flat vulcanizing machines, specifically a fully automatic mold-opening rubber flat vulcanizing machine. Background Technology

[0002] Flat vulcanization is one of the basic processes in rubber product processing. Flat vulcanizing machines are suitable for vulcanizing various rubber products and are advanced hot-pressing equipment for molding various thermosetting plastics. Their main function is to provide the pressure and temperature required for vulcanization. Rubber flat vulcanizing machines are typically equipped with an automatic mold opening system, which can automatically open and close the mold without manual intervention.

[0003] The existing technology has the following shortcomings: In the existing technology, the "Fully Automatic Rubber Flat Vulcanizing Machine with Mold Opening" with application number 202122492070.1 "includes a vulcanizing machine body, the vulcanizing machine body includes a base plate, a mounting seat is provided on one side of the top of the base plate, guide rods are provided at the four corners of the top of the mounting seat, a limiting plate is provided on the top of the outer side of the guide rods, a mold body is provided between the limiting plate and the mounting seat, a hydraulic cylinder is provided at the center of the top of the limiting plate, and mold opening auxiliary structures that can realize the automatic mold opening of the vulcanizing machine are provided on both sides along the length direction between the limiting plate and the mold body, and an ejection structure that can facilitate the removal of rubber products by the staff is provided inside the mounting seat";

Furthermore, the aforementioned equipment inevitably generates harmful gases during the hot pressing process of rubber products, and these devices typically lack the ability to purify the generated gases. Direct emission of untreated gases can easily cause air pollution around the equipment, thus the environmental friendliness of the equipment could be further improved. Utility Model Content

[0039] The working principle and usage process of this utility model are as follows: The operator first checks whether the relevant components are installed in the correct position. When the mold needs to be replaced, the four sets of positioning blocks 805 are rotated in sequence to move them away from the limiting plate 802 and align them with the positions of the magnet blocks 806 on the base 3. Due to the magnetic attraction between the positioning blocks 805 and the magnet blocks 806 on the base 3, the position of the positioning blocks 805 is fixed. The upper mold 4 and the lower mold 5 are moved outward to make the limiting plate 802 disengage from the mounting groove 803, thus completing the disassembly of the upper mold 4 and the lower mold 5. The above operation is performed in reverse to complete the installation of the mold to be replaced. At this time, the positioning blocks 805 are in contact with the limiting plate 802, which can limit and fix the limiting plate 802. Due to the magnetic attraction between the positioning blocks 805 and the magnet blocks 806 on the limiting plate 802, the positioning blocks 805 will not rotate arbitrarily, and the mold is fixed. The disassembly and assembly of the mold are relatively convenient. This structure can facilitate the quick replacement of the mold and thus adapt to the production of rubber products of different shapes (sizes).

[0040] When using the equipment, the required curing time for the rubber is selected through the control panel of the control box 2. The rubber to be processed is placed on top of the lower mold 5. The heating components on the base 3 can heat the upper mold 4 and the lower mold 5. The electric push rod 6 runs to press the upper mold 4 down and perform curing work on the rubber to be processed. After the time selected by the control panel is completed, the electric push rod 6 runs to lift the upper mold 4 up, which can automatically complete the mold opening work. During this process, the suction fan 16 runs to finally generate suction at the bottom of the suction plate 9. The gas generated in the processing box 1 will be transported to the cavity 10 through several sets of through holes 11, and finally transported to the clean air box 15 through the air supply pipe 14. The activated carbon in the clean air box 15 can purify the gas. The treated gas will finally be discharged through the exhaust pipe 17. Several sets of dispersed through holes 11 can increase the suction coverage of the suction plate 9. This structure can purify the gas generated in the processing and further improve the environmental protection of the equipment.

[0041] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
