A continuous circulating operation of plastic pipe mold cooling device

Abstract

The invention discloses a plastic pipe mould cooling device capable of carrying out continuous circulating operation. The plastic pipe mould cooling device capable of carrying out continuous circulating operation comprises at least two plastic pipe moulds, wherein each plastic pipe mould comprises at least two mould bodies which carry out circulating operation along annular rails, the mould bodies on the plastic pipe moulds are correspondingly arranged in a one-to-one mode, a cooling water cavity is arranged inside each mould body, and each cooling water cavity is communicated with a cooling water movement pipeline. Due to the fact that water inlets and water outlets of the plastic pipe moulds are connected with cooling water circulating pipelines in a one-to-one mode through water feeding pipelines and water discharging pipelines, a cooling water circulating channel is a totally-closed pipeline, leakage cannot easily happen, and the fault rate is low; due to the fact that operation of the cooling water feeding pipelines, the cooling water discharging pipelines and operation of rotation pipeline converters are in continuous same-direction movement, movement impact is low, and the service life is long; due to the fact that a drive system is in gear drive and chain wheel and chain drive, the drive ratio is constant, the same power source is used by the drive system and is used for drive of the plastic pipe moulds, and elimination of malfunctions is ensured. The plastic pipe mould cooling device capable of carrying out continuous circulating operation has the advantages of being high in cooling efficiency, stable and reliable in operation, and capable of carrying out high-speed and high-efficiency operation.

Description

technical field [0001] The invention relates to a cooling medium (water, oil, etc.) circulation device for plastic pipe moulds. [0002] Generally speaking, the utility model relates to a plastic pipe mold cooling device which operates in continuous circulation. Background technique [0003] At present, the cooling water circulation pipeline of the plastic pipe mold used for continuous circulation operation is divided into two types according to the structure. One is that the water inlet and return pipes are fixed, and the cooling water is continuously injected from the top of the mold into the cooling water chamber of the plastic pipe mold in continuous circulation through the water inlet pipe, and then discharged from the bottom of the plastic pipe mold, flows into the recovery tank, and then flows through the return pipe. Return to the water tank to complete a cycle. The disadvantage of this kind of cooling is that because the cooling water circulation pipeline is an op...

Problems solved by technology

The disadvantage of this kind of cooling is that the reciprocating movement of the inlet and return pipes produces impact, which makes the equipment unable to operate continuously and stably, and the impact becomes more obvious as the speed increases, and the disadvantages become more prominent, which seriously affects the high-speed and efficient operation of the equipment.
