In an embodiment of the above improved hot mold cooling structure in the prior art, the working plate 1 and the cooling back plate 2 are of a split structure.
In one embodiment of the prior art, the working plate 1 and the cooling back plate 2 are an integral structure.
The present embodiment differs from the prior art in the specific connection manner of the cooling medium feeding line and the cooling medium discharging line, specifically:
the cooling medium feeding pipeline comprises a first connecting pipe 4, a compressed air feeding pipe 6 and a circulating water feeding pipe 7, one end of the first connecting pipe 4 is connected with a cooling medium inlet of the cooling back plate 2, the other end of the first connecting pipe 4 is connected with the compressed air feeding pipe 6 and the circulating water feeding pipe 7, a first control valve 13 is arranged on a passage through which the compressed air feeding pipe 6 is communicated with the first connecting pipe 4, and a second control valve 14 is arranged on a passage through which the circulating water feeding pipe 7 is communicated with the first connecting pipe 4.
The cooling medium sending pipeline comprises a second connecting pipe 10, one end of the second connecting pipe 10 is connected with a cooling medium outlet of the cooling back plate 2, the other end of the first connecting pipe 4 is used as a water return end to be connected with a circulating water source, a third control valve 15 is arranged between the second connecting pipe 10 and the circulating water source, a compressed gas discharge pipe 12 is communicated with a position, closer to the cooling medium outlet of the cooling back plate 2 than the third control valve 15, on the second connecting pipe 10, and a fourth control valve 16 is arranged on the compressed gas discharge pipe 12.
The improved hot mold cooling structure provided in this embodiment can facilitate switching between compressed air and circulating water, and specifically, as can be seen from fig. 1, the cooling pipeline of this embodiment is provided with a set on the hot mold body, wherein the cooling medium feeding pipeline is located on the lower side of the cooling back plate 2, and the cooling medium discharging pipeline is located on the upper side of the cooling back plate 2, when switching to the compressed air operation mode, only the second control valve 14 and the third control valve 15 need to be in a closed state, and the first control valve 13 and the fourth control valve 16 are in an open state, so that compressed air can be fed from the compressed air feeding inlet 8, reach the first connecting pipe 4 through the compressed air feeding pipe 6, then enter the inlet on the lower side of the cooling back plate 2 from the first connecting pipe 4, and travel in the cooling passage in the cooling back plate 2 to carry heat generated during hot mold casting, and then exit from the outlet on the upper side of the cooling back plate 2 to the second connecting pipe 10, and since the third control valve 15 is in a closed state, the fourth control valve 16 is in an open state, air carrying heat can be discharged from the compressed air discharge pipe 12 (directly into the environment or discharged to another environment).
When the circulating water working mode is switched, only the second control valve 14 and the third control valve 15 need to be in an open state, and the first control valve 13 and the fourth control valve 16 are in a closed state, so that circulating water can enter from the circulating water inlet 9, reach the first connecting pipe 4 through the circulating water feeding pipe 7, then enter the inlet on the lower side of the cooling back plate 2 from the first connecting pipe 4, and move in the cooling passage in the cooling back plate 2 to bring heat generated during hot mold casting, and exit from the outlet on the upper side of the cooling back plate 2 to enter the second connecting pipe 10, because the third control valve 15 is in an open state, the fourth control valve 16 is in a closed state, and heated circulating water carrying heat can return to a circulating water source (a water tower or a water tank) through the circulating water return port 11.

Example 2
When different parts of the hot mold need different cooling speeds, for example, in directional solidification, the hot mold needs different cooling speeds from bottom to top, one of the existing means is to arrange cooling medium channels with different apertures and/or coverage rates from bottom to top on the cooling back plate of the hot mold, the heat exchange in cooling is adjusted by the self structure of the cooling channel, and the other is to adjust the heat exchange in cooling by adjusting the pressure and/or flow of the cooling medium, both of which have disadvantages. This embodiment provides another improved thermal die cooling structure on the basis of embodiment 1, thereby enabling the combined use of different cooling media according to the cooling needs of different parts of the thermal die.
As shown in fig. 2, the cooling back plate 2 in this embodiment at least comprises a first back plate portion 2-1 and a second back plate portion 2-2 from bottom to top, and the first back plate portion 2-1 and the second back plate portion 2-2 have respective cooling passages therein. In this embodiment, the height of the first back plate portion 2-1 is preferably greater than the height of the second back plate portion 2-2, which is more suitable for the control principle of directional solidification of an ingot (or a casting).
In this embodiment, the first backplate portion 2-1 and the second backplate portion 2-2 each have a set of cooling lines as described in embodiment 1. Specifically, of the cooling lines provided in the first back plate portion 2-1, the same cooling medium feed line as in embodiment 1 is provided on the lower side of the first back plate portion 2-1, and the same cooling medium discharge line as in embodiment 1 is provided on the upper side of the first back plate portion 2-1; of the cooling pipes provided in the second back plate portion 2-2, the same cooling medium feed pipe as in embodiment 1 is provided on the lower side of the second back plate portion 2-2, and the same cooling medium feed pipe as in embodiment 1 is provided on the upper side of the second back plate portion 2-2.

It should be noted that, in this embodiment, it is only a better means than the prior art to combine and use different cooling media according to the cooling requirements of different parts of the hot mold, and the means is not necessarily used alone, but other means in the prior art may be combined and used, for example, a means of combining the aforementioned cooling back plate of the hot mold with cooling medium channels having different apertures and/or coverage rates from bottom to top, or a means of regulating and controlling the pressure and/or flow rate of the cooling medium, and the like.
Similarly, although fig. 2 illustrates that the cooling back plate 2 includes a first back plate portion 2-1 and a second back plate portion 2-2 from bottom to top, this is not limited in number, and a third, a fourth or even more back plate portions may be further extended, and respective cooling passages are also provided in the back plate portions and the cooling pipes described in this embodiment are installed, which will not be described again.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
