Pull rod lock mode hydraulic tyre vulcanizer

Abstract

The invention discloses a hydraulic tire curing press with a pull rod locking module. The invention consists of a frame consisting of a lower beam and a supporting part, an upper beam, an upper and lower thermal plate, an opening and closing die cylinder, a central structure and a pressurized structure. The upper beam is driven by the opening and closing die cylinder and has freedom of moving fromthe top to the bottom. An upper die and a lower die are directly arranged between the upper thermal plate and the lower thermal plate and are respectively fixed connected with the upper beam and thelower beam. The pressurized structure consists of a pulling rod, a pressurized splint and a pressurized cylinder. The pulling rod is evenly arranged corresponding to the axle wire of in the tire module. The upper terminal of each pulling rod is fixedly connected with the upper beam and the lower terminal of each pulling rod is fixedly connected with the pressurized plate traveling through the lower beam; the pressurized cylinder is fixed on the bottom of the lower beam and the piston terminal of the cylinder is fixedly connected with the pressurized plate; the pulling rod is arranged with a locking die structure and an adjusting die structure. The invention increases the working precision and reducing the manufacturing cost, at the same time, the invention also has the advantages of avoiding the problem of oil leaking and contamination, being convenient for the cylinder maintenance, simplifying the forcing chain of the locking die force and reducing the manufacturing cost of the curingpress.

Description

technical field [0001] The invention relates to a tire vulcanizing equipment, in particular to a hydraulic tire vulcanizing machine in a pull bar lock mode. Background technique [0002] The vulcanization of automobile tires has been popularized and applied since the 1950s, and the mechanical vulcanizer is generally used at first. The high requirements also put forward higher and higher requirements for the working precision of the vulcanizing machine. Therefore, the hydraulic vulcanizing press with higher working precision has gradually replaced the traditional mechanical vulcanizing press. [0003] Existing hydraulic tire vulcanizing machines include two types of frame structure and column structure, the difference mainly lies in that the main support structure adopts a fixed beam type frame or a column. Taking the hydraulic tire vulcanizing machine with frame structure as an example, a common structure includes frame body, upper beam, mold opening and closing cylinder, u...

Problems solved by technology

However, in order to realize the upward pressure of the lower mold, the lower mold in the lower structure of the pressurized cylinder cannot be directly fixed with the support structure, but is floating. Due to the existence of the gap, it is inevitable that the alignment during mold closing Decrease in accuracy; Secondly, the location of the pressurized cylinder greatly increases the maintenance difficulty and cost of the pressurized cylinder
