Radial tire molding curing bladder molding device

Abstract

The invention discloses a radial tire molding curing bladder molding device. The device comprises a base, a body, supporting columns, an upper workbench, a lower workbench, an upper core ejector mechanism, a lower core ejector mechanism, a lifting cylinder and a hydraulic oil cylinder, the upper core ejector mechanism is arranged on the body, the ejector head at the bottom of the upper core ejector mechanism is adapted to the bladder ejector port of the upper workbench, the lower core ejector mechanism is arranged on the base, the ejector head at the top of the lower core ejector mechanism is adapted to the bladder ejector port of the lower workbench, the top end of the weightlifting rod of the lifting cylinder is connected with the upper workbench, and the weightlifting member of the hydraulic oil cylinder is connected with the lower workbench. A technical problem of the division of the device working operation is solved by the radial tire molding curing bladder molding device. The radial tire molding curing bladder molding device has the advantages of effective reduction of the loss of the hydraulic oil cylinder, prolongation of the service life, die locking time reduction, reduction of the time for the rubber scorching in the die locking process, rubber safety ensure, production cost reduction, and production efficiency improvement.

Description

[0001] technical field [0002] The invention relates to a vulcanization bladder molding equipment, in particular to a radial tire molding type vulcanization bladder molding equipment. Background technique [0003] Generally, pneumatic rubber tires are obtained by molding and curing partially qualitative green (unvulcanized) tires in a molding press. In the rubber tire molding and curing process, an inflatable bladder filled with a fluid at an appropriate temperature is used to press the green tire outward against the inner surface of the vulcanizer mold. With this method, the green tire is set against the outer mold surface that defines the tire's tread pattern and sidewall configuration. Tires are molded and vulcanized under defined temperature and pressure conditions. In this process, the role of the curing bladder is particularly important. [0004] At present, the commonly used bladder vulcanizers at home and abroad have complex structures. The ejection cylinder adop...

Problems solved by technology

[0004] At present, the commonly used capsule vulcanizing machine at home and abroad has a complex structure. The ejection cylinder adopts one stroke, and the airbag chamber is used for cooling. The efficiency is low, the cost is high, the maintenance is difficult, the use is cumbersome, the energy consumption is large, and the product quality is low.

With the development of the rubber product industry, this type of equipment is far from meeting the needs of development
