Description

Technical Field

[0001] The invention relates to the field of rubber tire production equipment, in particular to a tire vulcanization device. Background Art

[0002] Existing tire vulcanization equipment generally includes a heated upper mold and a lower mold, the lower mold is placed horizontally, and the upper mold can be raised and lowered in the vertical direction relative to the lower mold. When the tire is vulcanized, the tire is placed in the lower mold, the upper mold descends and closes with the lower mold, the upper mold and the lower mold heat and vulcanize the tire, and after the vulcanization is completed, the upper mold rises and the tire is taken out. However, when the tire is processed in the existing vulcanization equipment, it is inconvenient to take and put, and it is easily interfered by the upper mold. Moreover, after the upper mold and the lower mold are closed, the upper mold must be pressed down by a hydraulic device arranged above the upper mold, and the hydraulic device limits the working space and lighting environment. When vulcanizing the inner tube, because the inner tube has an air nozzle structure, the air nozzle needs to be inflated while vulcanizing. After the inner tube is placed in the lower mold of the existing vulcanization device, the lower mold is difficult to observe, and it is very inconvenient to do the inner tube alignment and the action of connecting the air nozzle.

[0008] Preferably, the table can be raised and lowered obliquely relative to the base. The table can be lowered before the upper cover is opened and flipped up, so that the ring body can rotate to move the protrusion out of the slot of the arm. After the protrusion moves into the slot, the table can rise to press the upper mold and the lower mold.

[0009] Preferably, it also includes a mold closing cylinder and a locking cylinder, one end of the mold closing cylinder is hinged to the base and the other end is hinged to the upper cover, one end of the locking cylinder is hinged to the upper cover and the other end is hinged to the ring body.
