Description

Vulcanizing equipment

Technical Field

The utility model relates to the technical field of rubber vulcanization equipment, in particular to vulcanization equipment for a rubber soft joint.

Background

Vulcanization is the last process step, and most importantly, of rubber products, which changes the rubber into a highly elastic or hard crosslinked rubber through a series of complex chemical reactions, thereby obtaining corresponding mechanical and chemical properties of the rubber. Unvulcanized rubber is a linear large-structure molecule, and when the unvulcanized rubber is subjected to external force, the large-structure molecule can displace, and the unvulcanized rubber is particularly obviously deformed. After the rubber is vulcanized, the molecular structure of the rubber can form a net shape, and the movement of macromolecules is limited, so that the vulcanized rubber has better tensile strength and elastic strength than unvulcanized rubber.

The rubber soft joint is a special rubber product (the finished product structure can refer to Chinese appearance patent CN 305496695S), the final molding and vulcanization are completed in the last process, the former process is to sleeve the manufactured cylindrical rubber blanks (with large inner diameters at the upper end and the lower end and small inner diameter in the middle and large difference from the appearance of the finished rubber soft joint) on a vulcanization liner, and the rubber blanks are placed in a mold together, and the subsequent molding and vulcanization are carried out in the mold; because the shape of the rubber blank and the shape of the rubber soft joint are greatly different, the rubber blank is heated in the die in the forming process, and after the rubber blank is softened by heating, the vulcanization liner is inflated, and the vulcanization liner expands the rubber blank and presses the rubber blank to the die for forming.

The traditional manufacturing process is that the mould is provided with four mutually matched moulds, the upper and lower moulds can form a plurality of inner cavity spaces after being butted, and each inner cavity space is used for loading a vulcanization inner container sleeved with a rubber blank; the left block and the right block are used for butt joint and pressing and inflating the vulcanized liner. In order to improve production efficiency, the existing manufacturing process is designed into semi-automatic equipment, when the manufacturing process is specifically performed, a lower die automatically stretches out, a worker transversely places vulcanized inner containers sleeved with rubber blanks on the lower die one by one, after the placement is finished, the lower die retracts, an upper die is pressed down, the upper die and the lower die are clamped to form an inner cavity space, a left die and a right die are extruded towards the middle to be clamped until the upper die and the lower die are aligned with the two ends of the upper die and the lower die, when the left die and the right die are extruded towards the middle, an air needle arranged on the left die and the right die is accurately inserted into a hole of the vulcanized inner container, after the step is completed, the vulcanizing machine starts to work, heats the dies, inflates the vulcanized inner containers after the vulcanized inner containers expand, the rubber blanks are extruded onto the inner walls of the dies, and the appearance of the rubber soft joint is formed.

However, the prior art has technical defects that when the upper and lower molds are clamped and the left and right molds are pressed and clamped towards the middle, air needles arranged on the left and right molds cannot be accurately inserted into holes of the vulcanization liner, so that the air needles are damaged, the production fails, and the rejection rate is increased. Therefore, the applicant designs a novel vulcanizing device which does not need to conduct pin inserting operation on the vulcanizing inner container, avoids damaging the air pin, improves the survival efficiency and reduces the rejection rate.
