Description

TECHNICAL FIELD

[0001] The application relates to the technical field of rubber vulcanization equipment, in particular to an intelligent temperature control rubber vulcanization and forming integrated device. BACKGROUND

[0002] Rubber vulcanization is a key process in the production of rubber products. Through heating and pressing, the chain molecules of rubber are crosslinked to obtain the required physical properties such as elasticity, strength and durability. Traditional rubber vulcanization forming usually uses a flat vulcanization machine, which has a basic structure including a fixed lower mold plate and an upper mold plate that is lifted and lowered by hydraulic or mechanical drive. During operation, the preformed rubber semi-finished product (material to be processed) is placed in the mold cavity of the lower mold plate by manual or simple auxiliary tools, and then the mold is closed for heating and pressing vulcanization. After vulcanization is completed, the mold is opened and the product is manually taken out.

[0003] With the development of industrial automation, in order to improve production efficiency, some vulcanization equipment with automatic feeding or taking mechanism appears. For example, some equipment sets a linear feeding track on one side of the vulcanization machine to push the material into the mold; some use mechanical arms for feeding and discharging. However, these improved schemes still have many limitations: production efficiency and flexibility are insufficient: most of the automation schemes are still designed around a single upper and lower mold plate, or use a linear arrangement of multiple stations, and the production cycle is limited by the sequence of mold closing, vulcanization, mold opening and material taking. It cannot realize overlapping operation, and the production capacity is limited. The connection between feeding, positioning, vulcanization and material taking processes is not close enough. The accurate positioning of the material in the mold depends on the guidance of the mold itself or simple mechanical limiting, and lacks an active and feedback positioning correction mechanism. Especially when dealing with complex shaped rubber parts with central holes or specific positioning holes, positioning deviation may cause product flash, uneven thickness or even scrap. Therefore, a new intelligent temperature control rubber vulcanization and forming integrated device has become a problem that needs to be solved by those skilled in the art SUMMARY
