Specific embodiment

The embodiments of the present invention are described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning Same or similar element or element with the same or similar functions are indicated to same or similar label eventually.Below by ginseng The embodiment for examining attached drawing description is exemplary, and is only used for explaining the utility model, and should not be understood as to the utility model Limitation.

As shown in Figure 1-3, a kind of type core point device for cooling that the present embodiment proposes, it includes type core 1, is equipped with inside type core 1 Type chamber 11, the bottom of type core 1 are equipped with internal screw thread in type chamber 11, and type core 1 has been connected through a screw thread with the cold pipe 2 of externally threaded point, It is equipped with the first lumen 21 inside the cold pipe 2 of point, the first lumen 21 is connected with type chamber 11, further, type core 1 and the cold pipe 2 of point It is coaxially set.

The other end of the cold pipe 2 of point is connected with connector 3, advantageous, and in order to facilitate processing, putting cold pipe 2 and connector 3 can be one Bodyization production, connector 3 are equipped with water inlet 31 and water outlet 32, and water inlet pipe 6 is equipped at water inlet 31, advantageous, water inlet pipe 6 with Type chamber 11 is coaxially set, and the diameter ratio of the diameter of water inlet pipe 6 and the first lumen 21 is 1:2-3, water inlet pipe 6 and extraneous high pressure Water pipe is connected, and guarantees that water velocity is fast using high-pressure water pipe, to improve cooling effect；Water inlet pipe 6 passes through the first lumen 21 The top position of type chamber 11 is extended to, water outlet 32 is connected with the first lumen 21.It can thus be seen that by using One lumen 21 is drained, and 21 diameter of the first lumen is bigger than 6 diameter of water inlet pipe, and it is aquatic because recycling to efficiently solve outlet pipeline The problem of being blocked at scale；In addition, also in type core 1 and point water pipe 2 water can be arranged completely after shut-down cycles water Out, it does not remain, it is very convenient, it kills two birds with one stone.

The lower section of type core 1 is additionally provided with type core extension device 4, and type core extension device 4 is set on a little cold pipe 2, in order to prolong to type core Long part 4 is limited, and position-limit mechanism is equipped with below type core extension device 4, advantageous, and position-limit mechanism can be nut 5, in Dian Shui External screw thread also is provided on 2 outer wall of pipe, nut is threadedly attached on a water pipe 2.Further, type core extension device 4 is straight Diameter is equal with the diameter of type core 1.By being equipped with type core extension device 4 and nut 5, extended pattern core 1 on the one hand can be convenient Length meets different use demands, on the other hand, by the setting of nut 5, also strengthens type core 1 and puts the connection of water pipe 2 Stability, it is vdiverse in function, it is simple and practical.

Specific use process is as follows:

When in use, water inlet pipe 6 is connected with extraneous high-pressure water pipe, cooling water reaches up to type chamber 11 along water inlet pipe 6 Top position at spray, cooling water directly contacts with type chamber 11 and absorbs heat, and rate of heat exchange is exceedingly fast, and absorbs the cold of heat But water flows to 32 position of water outlet along the first lumen 21, is discharged through water outlet 32.In the process, constantly have again new cold But water is flowed into from water inlet 31, in this way, cooling water ceaselessly circulates in water inlet pipe 6 and the first lumen 21, it is cold in type chamber 11 But water remains stable heat exchanger effectiveness, and the cooling velocity of type core 1 is exceedingly fast, thus real in the utility model energy short time Now to the fast cooling of type core 1, casting demoulding deformation is prevented, shortens the molding cycle of product, product is avoided quality problems occur, Increase substantially product qualification rate.

While there has been shown and described that the embodiments of the present invention, it will be understood by those skilled in the art that: These embodiments can be carried out with a variety of variations, modification, replacement in the case where not departing from the principles of the present invention and objective And modification, the scope of the utility model are defined by the claims and their equivalents.
