Balance type tire vulcanizing machine

Abstract

The invention provides a balance type tire vulcanizing machine. The balance type tire vulcanizing machine comprises a base, a cross beam, long guide pillars, a pull rod, a top beam, a mold opening andclosing oil cylinder, a pressurizing oil cylinder and a mold locking mechanism; two tire vulcanizing stations are arranged on the base and share the cross beam; and the cross beam moves up and down along two long guide pillars arranged on the front sides and the rear sides of the middles of the two vulcanizing stations. The die opening and closing oil cylinder is arranged on the top beam at the upper part of the cross beam, and no other parts need to be arranged between the two stations, so that the two stations are capable of being approached to the greatest extent, and the occupied space ofthe balance type tire vulcanizing machine is greatly reduced; with the decrease of the span between the two stations, the sizes of structural parts such as the cross beam are reduced, the rigidity isobviously improved, and the quality of vulcanized tires is obviously improved; and the mold locking mechanism cooperates with long guide pillars or the pull rod to act through multiple ring grooves,and compared with single clamping groove mold locking in a traditional mold locking mechanism, the depths of the ring grooves on the long guide pillars or the pull rod can be reduced and the outer diameter sizes of the long guide pillars or the pull rod can also be correspondingly reduced, so that the manufacturing cost is reduced and the mold locking reliability is improved.

Description

technical field [0001] The invention relates to tire vulcanizing equipment, in particular to a balance type tire vulcanizing machine. Background technique [0002] The traditional tire vulcanizing machine is a fixed frame type. Generally, a set of molds is installed in one vulcanizing machine. Its structure is stable, but it takes up a lot of space, the structure of the device is heavy, and it is difficult to maintain. [0003] Generally, two sets of molds are installed on one machine, and a mold opening and closing cylinder is installed at the center of the two molds. The structure is more compact and can effectively save space. In the patent document with the notification number CN100572021C, a hydraulic tire vulcanizing machine with column clamp lock mode is disclosed, which includes a base, a liftable upper beam, a column for mold opening and closing and bearing clamping force, and a mold opening and closing Oil cylinder, pressurized oil cylinder, and lower supporting p...

Problems solved by technology

In the patent document with the notification number CN100572021C, a hydraulic tire vulcanizing machine with column clamping plate lock mode is disclosed, which includes a base, a liftable upper beam, a column for mold opening and closing and bearing clamping force, and an opening and closing mold. Oil cylinder, pressurized oil cylinder, and lower supporting plate, among which the mold opening and closing cylinder is set on the base and is at the center of the two molds. Since the two molds share a mold opening and closing cylinder, in order to meet its bearing capacity, it is necessary to choose a larger cylinder. , that is, the distance between the two molds is increased, which brings two disadvantages: one is that the vulcanizer occupies a larger area, and the other is that the upper beam will become longer, and the bending deflection will become larger, so the upper beam needs to be reinforced structure, the weight will increase accordingly

[0004] In the tire vulcanizing machine, the center mechanism is an important part for manipulating the bladder. The center mechanism is installed in the hot plate mechanism of the tire vulcanizer. The center mechanism needs regular maintenance. During maintenance, the connecting pipeline on the center mechanism is usually removed. Hoisting from above the hot plate, due to the complex connection pipeline on the central mechanism, the disassembly is cumbersome, the maintenance time is long, and the equipment is shut down for a long time
