Description

Technical Field

[0001] The utility model relates to the technical field of vulcanization equipment, in particular to a rapid connection device between a mold and a vulcanizer. Background Art

[0002] At present, the connection between the vulcanizer and the mold is usually realized by screws. Specifically, connection slots or connection screw holes are designed on the lower mold, and corresponding installation holes and T-nuts are reserved on the lower steam chamber of the vulcanizer. The screw passes through the connection slot or connection screw hole and is threadedly connected with the T-nut, so that the lower mold can be fixed on the lower steam chamber of the vulcanizer. In the actual production process, the operator needs to stand on the operation platform or the vulcanizer and use a tool wrench to install or disassemble the screw and the T-nut. This not only has a large labor intensity and a great potential safety hazard, but also the problem that the screw is easy to loosen after being tightened easily occurs.
