It is cavity between mould and cover half, when injection molding is needed dynamic model and cover half being affixed, squeezed the raw material of molten state using injection (mo(u)lding) machine
Enter in cavity, then mold cooled down again, molten state raw material cools down therewith, and gradually solidifies, ultimately form with it is identical
Workpiece.
Current injection mold generally uses water cooling, in mold periphery setting for cold water by pipeline, when needing cooling,
Cold water is passed through into pipeline, the heat in mold passes sequentially through mold, pipe side wall enters in water, and the temperature of mold reduces, mould
Material temperature in tool reduces and is progressively solidified into type.From the hot water being discharged in pipeline need to be sent into other storage device into
Row cooling, so needing to be laid with the water inlet pipe and outlet pipe being connected to every lathe in workshop, the pipeline in workshop is various,
Also it can increase the risk of pipeline fault while occupying workshop space.Secondly, pipeline is generally pylindrical, cylindrical pipe and mould
The contact area of tool is smaller, and the speed in the water in heat transfer to pipeline on mold is slower, can also cooling velocity be made to reduce.
Invention content
The purpose of the present invention is to provide a kind of water cooling injection moldings for the number of tubes that reduction workshop is connected to extraneous water inlet pipe
Mold.
In order to achieve the above objectives, the technical scheme is that：A kind of water cooling injection mold, including rack, more it is L-shaped
