Abstract

The utility model provides a hydraulic tyre vulcanizing machine. A bearing ring of a paralleling machine is fixedly arranged on a lower cross beam. A bearing plate and the bearing ring can slide relatively; a fixing rod is connected with the bearing plate with a lower cross beam; a lower heat insulation mat and a lower heat plate are fixedly arranged on the bearing plate. An upper heat plate and an upper heat insulation mat are fixedly arranged on an upper supporting plate, whereas, an upper tire mold and a lower tire mold are fixedly connected with the upper heat plate and the lower heat plate; moreover, the bottom of a guide post is fixedly connected with the upper supporting plate, while top of the guide post is positioned in the perforation hole of the upper cross beam. The left and the right of the upper supporting plate are fixedly connected with a lifting oil cylinder and are driven by the lifting oil cylinder to ascend and descend. When mould is closed, the forcing cylinder at the top of the guide post forces the guide post to make the upper and the lower tire molds generate the required mold locking force. After finishing vulcanization, an operation mechanism drives the forcing cylinder to separate away the working place. The guide post passes through the upper cross beam to ascend and open the mould. The machine has the advantages of ensuing the same axle degree and parallel degree of the upper and the lower heat plates; so the utility model is capable of greatly reducing the influence of the heat plates to the forcing cylinder and decreasing the sealing aging and the fault of oil leakage; moreover, as a single cylinder conducts the closing pressurizing, the utility model promises even pressurizing force, simple structure and reliable performance as well as low cost and long service life.
