Abstract

The utility model provides a die core cooling device which comprises a first water pipe connector, a first pipeline, a second pipeline, a third pipeline and a second water pipe connector which are connected in sequence; wherein the first water pipe connector, the first pipeline, the third pipeline and the second water pipe connector are arranged in a die plate, and the second pipeline is arrangedin the die core. The die core cooling device is characterized in that the second pipeline is a spiral pipeline. The die core cooling device has the advantages of large cooling area and uniform cooling.

Description

Mold core cooling device

Technical field

The utility model relates to a kind of mold core cooling device, is used for the product temperature control relatively more responsive to mold temperature, belongs to mould temperature control technology field.

Background technology

Mould because the heat transmission of high temperature plastic cement fully can cause the mold temperature instability inadequately if cool off, causes the product size instability in injection moulding process.As shown in Figure 1, be traditional mold core cooling device schematic diagram, described mold core cooling device comprises first water pipe head 2 that connects successively, first pipeline 6, second pipeline 7, the 3rd pipeline 8 and second water pipe head 3, wherein, first water pipe head 2, first pipeline 6, the 3rd pipeline 8 and second water pipe head 3 are located in the template 4, second pipeline 7 is located in the core rod 1, second pipeline 7 is divided into inlet pipeline and outlet pipeline by water diversing sheet 5, water enters from first water pipe head 2, enter inlet pipeline through first pipeline 6, enter the 3rd pipeline 8 from the outlet pipeline outflow, derive, finish the core rod cooling from second water pipe head 3.Because the distance moved in core rod 1 of water route is long, the water temperature when core rod 1 enters and goes out just has bigger difference when the water route like this.And, can't take away enough heats because such water route is smaller to the film-cooled heat of core rod, and so just can't keep the temperature stabilization of core rod, and then cause the product size instability, can't carry out ordinary production.

Summary of the invention

The purpose of this utility model provides the stable control of a kind of energy mold temperature, guarantees the stable mold core cooling device of product size.

In order to achieve the above object, the technical solution of the utility model provides a kind of mold core cooling device, comprise first water pipe head, first pipeline, second pipeline, the 3rd pipeline and second water pipe head that connect successively, first water pipe head, first pipeline, the 3rd pipeline and second water pipe head are located in the template, second pipeline is located in the core rod, it is characterized in that described second pipeline is a spirality pipeline.

The utility model has the advantages that film-cooled heat is big, cooling evenly.

Description of drawings

Fig. 1 is traditional mold core cooling device schematic diagram;

Fig. 2 is a mold core cooling device schematic diagram of the present utility model.

The specific embodiment

Specify the utility model below in conjunction with embodiment.

Embodiment

As shown in Figure 2, be mold core cooling device schematic diagram of the present utility model, described mold core cooling device is made up of first water pipe head 2, first pipeline 6, second pipeline 9, the 3rd pipeline 8 and second water pipe head 3.First water pipe head 2, first pipeline 6, the 3rd pipeline 8 and second water pipe head 3 are located in the template 4, and second pipeline 7 is located in the core rod 1, and described second pipeline 9 is a spirality pipeline, adopt fortune water spiral part to make.

Water enters from first water pipe head 2, enters second pipeline 9 through first pipeline 6, flows out from second pipeline 9 to enter the 3rd pipeline 8, derives from second water pipe head 3, finishes the core rod cooling.

Because the water route evenly made progress when moving in core rod 1, so the temperature in core rod also can compare evenly.And the film-cooled heat of doing like this in core rod just can take away more heat more greatly, just can keep the temperature stabilization of core rod to the full extent, the stablizing of maintenance core rod, thus make mould can carry out ordinary production.

Claims

1, a kind of mold core cooling device, comprise first water pipe head (2), first pipeline (6), second pipeline (9), the 3rd pipeline (8) and second water pipe head (3) that connect successively, first water pipe head (2), first pipeline (6), the 3rd pipeline (8) and second water pipe head (3) are located in the template (4), second pipeline (7) is located in the core rod (1), it is characterized in that described second pipeline (9) is a spirality pipeline.
