Plugging air bag vulcanizing equipment

Abstract

The invention discloses plugging air bag vulcanizing equipment. The equipment comprises a support; an end cover inner mold, wherein the rear end face of the end cover inner mold is hinged to the support, a supporting face is arranged on the outer side face of the end cover inner mold, and the thickness of the end cover inner mold in the front-back direction is smaller than the width of the end cover inner mold in the left-right direction; an end cover outer mold arranged on the periphery of the end cover inner mold, wherein the side face, facing the end cover inner mold, of the end cover outer mold is provided with an abutting face, the abutting face is matched with the supporting face in shape, the end cover outer mold is provided with a heating part, and the heating part heats the abutting face; and a pressurizing part which drives the end cover outer mold to be close to the end cover inner mold, so that the distance between the abutting face and the supporting face is reduced. According to the plugging air bag vulcanizing equipment, the opening distance of an opening of a plugging air bag cylinder is reduced, finally, the opening is opened, the cylinder is taken down from the end cover inner mold, and tearing of the bonding position of the cylinder and an end cover is avoided. The plugging air bag vulcanizing equipment can be applied to the field of plugging air bag machining.

Description

technical field [0001] The invention relates to the field of plugged air bag processing, in particular to a plugged air bag vulcanization equipment. Background technique [0002] The plugging air bag is made of high-molecular synthetic materials such as rubber and fiber fabric through high-temperature vulcanization process, and is mainly used for drainage, sewage pipeline repair, and leak detection in closed water test. The existing plugging air bag is cylindrical, and the plugging air bag is composed of a cylindrical body and two end caps, and the cylindrical body and the end caps are bonded together by heat-bonding vulcanization molding process. The existing thermal vulcanization molding process is as follows: the airbag cloth is wound on the outer surface of the cylindrical inner mold to form a cylinder, and an opening extending in the axial direction is left on the side of the cylinder, and the airbag cloth and the inner mold are placed On the pressing heating device, t...

Problems solved by technology

[0003] However, the cylindrical inner mold has a large volume, and it is difficult to take out the inner mold from the opening after the end cap is bonded to the cylindrical body. The distance between the opening and the opening is relatively large, which may easily cause the bonding position between the cylindrical body and the end cap to tear
