[0002] The forming of rubber vulcanization airbags is a common production process for rubber products.

[0003] The main steps of this process include: First, prepare the required rubber materials and airbag molds; then, put the rubber materials into the molds and carry out vulcanization treatment by heating, pressurizing and other means.

[0004] During the vulcanization process, cross-linking reactions occur among rubber molecules, significantly improving their physical and chemical properties, such as increased strength, enhanced elasticity, and improved aging resistance.

[0040] The oil cylinder 4 is used to drive the upper pressing template. The synchronous driving mechanism 5 is used to drive the lower pressing template 13. The synchronous driving mechanism and the oil cylinder act synchronously to drive the upper pressing template and the lower pressing template to move towards or away from each other. When the upper pressing template and the lower pressing template move towards each other, the mold closing action is completed, and pressure is applied to the vulcanizing hot plate and the preheated plastic materials laid thereon; conversely, when the upper pressing template and the lower pressing template move away from each other, the mold opening action is completed.

[0041] As a preferred embodiment, guide holes are respectively formed at both ends of the upper pressing template. The guide posts 11 are slidably arranged in the guide holes. The oil cylinder 4 is connected to the upper pressing template.

[0042] Specifically, the oil cylinder is arranged upside down. The oil cylinder has a fixed end and a telescopic end. The fixed end of the oil cylinder is fixedly arranged on the frame, and the telescopic end of the oil cylinder is connected to the upper pressing template. The telescopic end of the oil cylinder extends out to push the upper pressing template downward along the axial direction of the guiding column to move downward.

[0044] As a preferred embodiment, the synchronous driving mechanism 5 includes: a moving seat 51, a gear disc 52, a rack 53, a cylinder 54, and a bull's-eye bearing 55.

[0045] Among them, the number of moving seats 51 is two. A third sliding groove is formed in the upper part of the base 1. The two moving seats 51 are slidably arranged in the third sliding groove. The two moving seats 51 are respectively movably supported on the guiding end faces 130.

[0049] For the rubber vulcanization airbag forming device of the present utility model, first lay the raw material plastic of the rubber vulcanization airbag on the preheating hot plate to preheat and keep warm the plastic in advance. After the plastic is preheated, pull out the preheating hot plate horizontally, and then lay the plastic on the vulcanizing hot plate.
