Description
Technical Field
The utility model relates to a plastic mold, specifically speaking are water-cooled plug cooling device.
Background
The water-cooled core rod of the existing plastic die is mostly formed by combining a left core rod and a right core rod, and because the left core rod and the right core rod have a gap when being combined, the phenomenon of leakage of cooling water can often occur, the cooling water can possibly flow into an extrusion cavity to influence the extrusion quality, and the flowing speed of the cooling water in the core rod can be reduced, so that the product quality during cooling and shaping is influenced, when the leakage is serious, the maintenance needs to be disassembled, the maintenance work is complex, and the workload is large.
Disclosure of Invention
The utility model aims at providing a novel structure, sealing performance is good, leak-free, reliable operation, the good water-cooled plug cooling device of cooling effect.
In order to achieve the purpose, the utility model comprises a sleeve, a left core rod, a water inlet pipe, a support plate, a right core rod, a water outlet pipe, a large O-shaped sealing ring, a small O-shaped sealing ring, a screw, a blocking plate and a positioning pin, wherein the upper part of the left core rod is provided with a horizontally placed water inlet hole, the lower part of the left core rod is provided with a horizontally placed water outlet hole, the left part of the left core rod is provided with an annular groove, the middle part of the left core rod is provided with a step hole, the left end of the water inlet hole is communicated with the left end of the water outlet hole through the annular groove, the left core rod is arranged in the sleeve, the blocking plate is welded at the left end of the left core rod and is arranged in the sleeve, the right core rod is arranged at the right end of the sleeve through the screw and the positioning pin, the large O-shaped sealing ring and the small O-shaped sealing, the water outlet pipe is connected and arranged in a threaded hole at the lower part of the right core rod through threads.
The utility model discloses because big O shape sealing washer and little O shape sealing washer are equipped with between left plug and the right plug, like this, the air pressure that has formed an inclosed space and at this inclosed space between big O shape sealing washer and little O shape sealing washer can be great, alright prevent effectively that the cooling water from leaking the emergence of phenomenon. The utility model discloses novel structure, sealing performance is good, does not have the leakage, and the reliable operation, the cooling effect is good.
