Rapid butt joint device for step forming runner

Abstract

The invention provides a rapid butt joint device for a step forming runner. The rapid butt joint device comprises a male connector assembly and a female connector assembly. The male connector assemblyand the female connector assembly each comprise a body, a movable core, a stop core, a filter screen, an elastic piece, a sealing ring and the like. One sides of the male and female joint assembliesare connected with a water source or an internal runner of a thermal forming mold. The male connector assembly is inserted into the female connector assembly to complete initial butt joint, the male connector assembly and the female connector assembly are in butt joint in place through a gear wrench, and a stop pin is inserted. After butt joint is completed, the movable cores in a male connector and a female connector are opened, fluid at the water source flows into the runner of the thermal forming mold through the butt joint device, and thermal forming mold cooling operation is conducted. The rapid butt joint device for the step forming runner has excellent sealing performance, and no fluid leaks in the whole butt joint process of the device; the filter screens are arranged inside, the production cooling effect can be guaranteed, and the service life of a mold and water circulation equipment is prolonged; and rapid and easy butt joint can be achieved through the gear wrench installedon the device, and the device is fixed through the stop pin after butt joint is completed and can be prevented from loosening.

Description

technical field [0001] The invention relates to the technical field of cooling systems for thermoforming molds, in particular to a rapid docking device for realizing fast docking in a flow channel environment with high water pressure, large flow rate and fast flow rate, preventing fluid leakage and purifying fluid. Background technique [0002] At present, the traditional butt joint method of the runner of the thermoforming mold is: the waterway switch assembly is used in conjunction with the quick-change male and female joint assemblies. When disassembling the mold in this way, the water switch needs to be turned off first, which is complicated to operate; there is no filtering device inside, which cannot filter impurities in the fluid, which has a great impact on the cooling effect and the life of the mold. In this docking method, when the male and female joint components are disassembled, residual fluid will leak from the connection between the quick-change joint and the ...
