[0035] A cooling device and a cooling method according to an embodiment of the present invention will be described with reference to FIGS. R shown in Figure 1 is a cooling device that cools the mold K of a manufacturing device, which pours molten metal or resin into the mold K to create a product shape, using a fluid (e.g., water).

[0036] The fluid (eg, water) passes through the mold K to cool, for example, the molten metal (eg, molten aluminum) inside the mold K. As shown in FIG. 1, the mold 1 has at least a first mold K1 and a second mold K2, and a space 1 is provided between the first mold K1 and the second mold K2. In addition, 2 in Figure 1 indicates a portion where cracks are likely to occur.

[0037] As shown in Figure 2, in a cross-sectional view, the first mold K1 has a first surface 11 which is the side of the molten metal or resin, a second surface 12 which is the surface away from the first surface 11, a third surface 13 which connects one side of the second surface 12 to one side of the first surface 11, and a fourth surface 14 which connects the other side of the second surface 12 to the other side of the first surface 11, with the second surface 12, third surface 13, first surface 11 and fourth surface 14 being positioned in a clockwise direction (see Figure 2).

[0038] Also, 3 shown in FIG. 2 is a first long straight line extending from the second surface 12 to the first surface 11. The hole 4 is a second long hole extending linearly from the second surface 12 to the first surface 11. The slot 2 and the first slot 1 are spaced apart from each other. 5 is linearly inserted from the third surface 13 (or the fourth surface 14) into the inside of the first mold K1. The third slot is connected to the first slot 3 and the second slot 4 . The first slot 3, the second slot 4, and the third slot 5 are formed by, for example, drilling. is formed.

[0039] Also, in Figures 4, 5 and 6, reference numeral 6 denotes a first insertion tube inserted (press-fitted) into the first long hole 3 so as to abut against it, reference numeral 7 denotes a second insertion tube inserted (press-fitted) into the second long hole 4 so as to abut against it, and reference numeral 8 denotes a third insertion tube inserted (press-fitted) into the third long hole 5 so as to abut against it. 5 denotes a sealing member that seals the opening of the outer end of the third insertion tube 8. Since the first insertion tube 6 and the second insertion tube 7 are connected to the third insertion tube 8, the cooling fluid (e.g., water) from the first insertion tube 6 can be guided to the third insertion tube 8 and the second insertion tube 7 to cool the first mold K1.

[0040] Therefore, according to the above-mentioned cooling device R, as shown in FIG. 3, the cooling fluid from the first insertion tube 6 is guided to the third insertion tube 8 and the second insertion tube 7, and the first mold K1 is indirectly cooled via the first, third, and second insertion tubes 6, 8, and 9. Since the cooling fluid is not guided directly to the first mold K1, it is possible to prevent cracks due to rust corrosion of the first mold K1 and defects in the molded product due to the cooling fluid seeping out into the molten metal caused by the cracks. Furthermore, since the cooling fluid is introduced and discharged from the second surface side, the installation of the cooling fluid can be easily performed.

[0041] The above-mentioned cooling device R can be understood as a cooling method for cooling the mold K of a manufacturing device that pours molten metal or resin into the mold K to create a product shape. The mold K has at least a first mold K1 and a second mold K2, as described above. The first mold K1 has a first long hole 3 that is linear from the second surface 12 toward the first surface 11, which is the side of the molten metal or resin, a second long hole 4 that is linear from the second surface 12 toward the first surface 11, and the second long hole 4 and the first long hole 3 are spaced apart from each other and extend linearly from a surface other than the first surface 11 and the second surface 12 (the third surface in this embodiment) toward the inside of the first mold K1 and communicate with the first long hole 3 and the second long hole 4. The cooling method includes a third long hole 5 inserted into the first long hole 3 so as to abut against the first long hole 3, a first insertion tube 6 inserted into the second long hole 4 so as to abut against the first long hole 3, a second insertion tube 7 inserted into the second long hole 4 so as to abut against the second long hole 5, and a sealing member 9 that seals the outer end of the third insertion tube 8, and the first insertion tube 6 and the second insertion tube 7 are connected to the third insertion tube 8, and the cooling fluid from the first insertion tube 6 is guided to the third insertion tube 8 and the second insertion tube 7, thereby cooling the first mold K1.

[0042] According to the above-mentioned cooling method, the cooling fluid from the first insertion tube 6 is guided to the third insertion tube 8 and the second insertion tube 7, and the first mold K1 is indirectly cooled via the first, third and second insertion tubes 6, 8 and 7. The cooling fluid is not guided directly to the first mold K1, so that cracks due to rust corrosion of the first mold K1 and defects in the molded product due to the cooling fluid seeping out into the molten metal caused by the cracks can be prevented. In addition, the inflow and outflow of the cooling fluid is performed from the side of the second surface 12, so that the installation of the cooling fluid can be easily performed (Figures 1 to 9, 12 and 13).

[0043] As shown in Figs. 1, 5 and 6, the first male screw provided at the tip of the first insertion tube 6 The screw 6X is screwed into a first female screw 81 provided on the third insertion tube 8, and a second male screw 7X provided at the tip of the second insertion tube 7 is screwed into a second female screw 82 provided on the third insertion tube 8. Therefore, the first, third and second insertion tubes 6, 8 and 7 can be easily connected from outside the first mold K1. It is possible to form a structure that is difficult to separate.

[0044] 5 and 6, the third insertion tube 8 is an eccentric tube whose outer diameter center and inner diameter center are different and whose wall thickness is also different, and the first female thread 81 and the second female thread 82 are provided in the thicker wall portion of the eccentric tube. Therefore, the first insertion tube 6 and the second insertion tube 7 can be firmly attached to the third insertion tube 8.

[0045] In the above embodiment, the third insertion tube 8 has one passage 8A. In the present invention, as shown in FIG. 7, a plurality of passages may be provided, for example, a first passage 8B, a second passage 8C, and a third passage 8D.

[0046] In the above embodiment, the first male screw provided at the tip of the first insertion tube 6 Although the second male thread 7X is provided at the tip of the second insertion tube 7, a tapered portion as shown in Figs. 8 and 9 may be used instead of the male thread. That is, as shown in Figures 8 and 9, the first tapered portion 6Y provided at the tip of the first insertion tube 6 abuts against the first hole portion 83 provided in the third insertion tube 8, and the second tapered portion 7Y provided at the tip of the second insertion tube 7 abuts against the second hole portion 84 provided in the third insertion tube 8, and the first tapered portion 6Y and the second tapered portion 7Y are tapered in the direction toward the third insertion tube 8. Therefore, the first, third and second insertion tubes 6, 8, 7 can be easily connected from outside the first mold K1, and the first, third and second insertion tubes 6, 8, 7 are less likely to come off the first mold K1. In addition, 6Z and 7Z shown in Figures 8 and 9 are male screws, and the male screws 6Z and 7Z are screwed into female screws (not shown) provided on the first mold K1 and tightened with a wrench (not shown) to firmly abut the first tapered portion 6Y provided at the tip of the first insertion tube 6 against the first hole portion 83, and the second tapered portion 7Y provided at the tip of the second insertion tube 7 against the second hole portion 84, respectively.

[0047] 8 and 9, the third insertion tube 8 is an eccentric tube whose outer diameter center and inner diameter center are different and whose wall thickness is also different, and the first hole 83 and the second hole 84 are provided in the thicker part of the eccentric tube. Therefore, the first insertion tube 6 and the second insertion tube 7 can be firmly attached to the third insertion tube 8.

[0048] Next, a description will be given with reference to Fig. 10. In Fig. 10, the second mold K2 of the mold K is omitted. 100 shown in Fig. 10 is a product in which molten metal or resin is poured into the space between the first mold K1 and a second mold (not shown) and solidified and cooled.

[0049] That is, in the embodiment of FIG. 10, the cooling device R, like the above, cools the die K of the manufacturing device that pours molten metal or resin into the die K to form the product shape. The mold K has at least a first mold K1 and a second mold not shown, and the first mold K1 has at least a first surface 11, a second surface 12, a third surface 13, a fourth surface 14, a fifth surface 15, and a sixth surface 16, where the first surface 11 is the side of the molten metal or resin, and the second surface 12 is the surface away from the first surface 11, and when viewed from the front of the fifth surface 15, the first surface 11 is to the right, the second surface 12 is to the left, the third surface 13 is above, the fourth surface 14 is below, and the sixth surface is on the back. The first insertion tube 6 is inserted (press-fitted) so as to abut against a linear first long hole (not shown) penetrating the fifth surface 15 and the sixth surface 16. The first insertion tube 6 is located closer to the first surface 11 than the second surface 12, and the first mold K1 is cooled by the cooling fluid from the first insertion tube 6.

[0050] The cooling device R of this embodiment is provided with a first linear long hole (not shown) penetrating the fifth surface 15 and the sixth surface 16, and a first insertion tube 6 inserted so as to abut (press-fit) into this first long hole (not shown). The first insertion tube 6 is located closer to the first surface 11 than the second surface 12, and the first mold K1 is cooled by cooling fluid from the first insertion tube 6. Therefore, the first mold K1 is indirectly cooled via the first insertion tube 6, and the cooling fluid is not directly guided to the first mold K1. This makes it possible to prevent cracks due to rust corrosion of the first mold K1 and defects in the molded product due to the cooling fluid leaking into the molten metal caused by the cracks.

[0051] In Figure 10, the first insertion tube 6 is inserted (pressed in) so as to abut against a linear first long hole (not shown) that penetrates the fifth surface 15 and the sixth surface 16. However, in some cases, although not shown, instead, a linear first' long hole (not shown) that penetrates the third surface 13 and the fourth surface 14 may be used, and a first' insertion tube (not shown) may be inserted (pressed in) so as to abut against this first' long hole (not shown), and the first' insertion tube (not shown) may be positioned closer to the first surface 11 than the second surface 12, and the first mold K1 may be cooled by cooling fluid from the first' insertion tube (not shown). According to the cooling device R of this embodiment, it is equipped with a linear first' long hole (not shown) that penetrates the third surface 13 and the fourth surface 14, and a first' insertion tube (not shown) that is inserted so as to abut against this first' long hole (not shown). The first' insertion tube (not shown) is located closer to the first surface 11 than the second surface 122, and the first mold K1 is cooled by cooling fluid from the first' insertion tube (not shown). Therefore, the first mold K1 is indirectly cooled via the first' insertion tube (not shown), and the cooling fluid is not directly guided to the first mold K1. This makes it possible to prevent cracks due to rust corrosion of the first mold K1 and defects in the molded product due to the cooling fluid leaking into the molten metal caused by the cracks.

[0052] Next, a description will be given with reference to Fig. 11. In Fig. 11, the second mold K2 of the mold K is omitted. 100 shown in Fig. 11 is a product in which molten metal or resin is poured into the space between the first mold K1 and a second mold (not shown), solidified, and cooled.

[0053] That is, in the embodiment of FIG. 11, the cooling device R, like the above, cools the die K of the manufacturing device that pours molten metal or resin into the die K to form the product shape. The mold K has at least a first mold K1 and a second mold (not shown). The first mold K1 has at least a first surface 11, a second surface 12, a third surface 13, a fourth surface 14, a fifth surface 15, and a sixth surface 16. The first surface 11 is the side of the molten metal or resin, and the second surface 12 is the surface farther from the first surface 11. When viewed from the front of the fifth surface 15, the first surface 11 is to the right, the second surface 12 is to the left, the third surface 13 is above, and the fourth surface 14 is below. A sixth surface 16 is located on the rear surface, and a first linear long hole (not shown) penetrating the fifth surface 15 and the sixth surface 16, a second linear long hole (not shown) penetrating the fifth surface 15 and the sixth surface 16, the second long hole (not shown) and the first long hole (not shown) are spaced apart, and a first insertion tube 6 is inserted (press-fitted) so as to abut against the first long hole (not shown), and a second insertion tube 7 is inserted (press-fitted) so as to abut against the second long hole (not shown). The first insertion tube 6 and the second insertion tube 7 are located closer to the first surface 11 than the second surface 12, and the first mold K1 is cooled by cooling fluid from the first insertion tube 6 and the second insertion tube 7. This cooling device R includes a first insertion tube 6 inserted so as to abut against a first long hole (not shown), and a second insertion tube 7 inserted so as to abut against a second long hole (not shown), and the first insertion tube 6 and the second insertion tube 7 are located closer to the first surface 11 than the second surface 12, and the first mold K1 is cooled by cooling fluid from the first insertion tube 6 and the second insertion tube 7. Therefore, the first mold K1 is indirectly cooled via the first insertion tube 6 and the second insertion tube 7, and the cooling fluid is not directly guided to the first mold K1. This makes it possible to prevent cracks due to rust corrosion of the first mold K1 and defects in the molded product due to the cooling fluid leaking into the molten metal caused by the cracks.

[0054] In FIG. 11, the first insertion tube 6 and the second insertion tube 7 are inserted (press-fitted) so as to abut against the linear first long hole (not shown) and the linear second long hole (not shown) penetrating the fifth surface 15 and the sixth surface 16. However, in some cases, it is possible to use a different method instead, which is not shown in the drawings. The mold K1 may be provided with a first' linear long hole (not shown) penetrating the third surface 13 and the fourth surface 14, a second' linear long hole (not shown) penetrating the third surface 13 and the fourth surface 14, the second' long hole (not shown) and the first' long hole (not shown) being spaced apart from each other, a first' insertion tube (not shown) inserted (pressed in) so as to abut against the first' long hole (not shown), and a second' insertion tube (not shown) inserted (pressed in) so as to abut against the second' long hole (not shown), and the first' insertion tube (not shown) and the second' insertion tube (not shown) are located closer to the first surface 11 than the second surface 12, and the first mold K1 may be cooled by cooling fluid from the first' insertion tube (not shown) and the second' insertion tube (not shown). Therefore, the first mold K1 is indirectly cooled via the first' insertion tube (not shown) and the second' insertion tube (not shown), and the cooling fluid is not directly guided to the first mold K1, thereby preventing cracks due to rust corrosion of the first mold K1 and defects in the molded product due to the cooling fluid leaking into the molten metal caused by the cracks.

[0055] Next, a description will be given with reference to Figures 14 and 15. In Figures 14 and 15, the second mold K2 of the mold K is omitted. Reference numeral 100 shown in Figure 15 is a product in which molten metal or resin is poured into the space between the first mold K1 and a second mold (not shown), solidified, and cooled.

The first insertion tube 6 is connected to the third insertion tube 8, the third insertion tube 8 is connected to the fifth insertion tube 10, the fifth insertion tube 10 is connected to the fourth insertion tube 9, and the fourth insertion tube 9 is connected to the second insertion tube 7, so that the first mold K1 is cooled by the cooling fluid of the first insertion tube 6, the third insertion tube 8, the fifth insertion tube 10, the fourth insertion tube 9, and the second insertion tube 7. Therefore, the first mold K1 is indirectly cooled via the first insertion tube 6, the third insertion tube 8, the fifth insertion tube 10, the fourth insertion tube 9, and the second insertion tube 7, and the cooling fluid is not directly guided to the first mold K1, thereby preventing cracks due to rust corrosion of the first mold K1 and defects in the molded product due to the cooling fluid leaking into the molten metal caused by the cracks. In the embodiment of Figures 14 and 15, the first insertion tube 6, the third insertion tube 8, the fifth insertion tube 10, the fourth insertion tube 9, and the second insertion tube 7 are provided in a single layer in the horizontal direction, but they may be provided in multiple stages in the vertical direction as shown in Figures 17 and 18.

[0058] That is, in the embodiment of FIG. 20, the cooling device R, like the above, cools the die K of the manufacturing device that pours molten metal or resin into the die K to form the product shape. The mold K has at least a first mold K1 and a second mold (not shown), the first mold K1 has at least a first surface 11, a first' surface 11', a first" surface 11", a second surface 12, a third surface 13, a fourth surface 14, a fifth surface 15, and a sixth surface 16, the first surface 11, the first' surface 11', and the first" surface 11" are the sides of the molten metal or resin, The second surface 12 is the surface farther from the first surface 11 and the first' surface 11'. When viewed from the front of the fifth surface 15, the first surface 11 and the first' surface 11' are located to the right, the second surface 12 is located to the left, the third surface 13 is located above, the fourth surface 14 is located below, and the sixth surface 16 is located on the back. The first surface 11 is located above the first'' surface 11'', and a straight line runs from the second surface 12 to the first' surface 11'. The mold K1 is provided with a first long hole (not shown), a linear second long hole (not shown) extending from the second surface 12 toward the first' surface 11', the second long hole (not shown) and the first long hole (not shown) being spaced apart from each other and extending linearly from the fifth surface 15 (or the sixth surface 16) toward the inside of the first mold K1 and communicating with the first long hole (not shown) and the second long hole (not shown), a first insertion tube 6 inserted (pressed in) so as to abut against the first long hole (not shown), a second insertion tube 7 inserted (pressed in) so as to abut against the second long hole (not shown), a third insertion tube 8 inserted (pressed in) so as to abut against the third long hole (not shown), and a sealing member 9 that seals the outer end of the third insertion tube 8. The first insertion tube 6 and the second insertion tube 7 are connected to the third insertion tube 8, and the cooling fluid from the first insertion tube 6 can be guided to the third insertion tube 8 and the second insertion tube 7 to cool the first mold K1. Therefore, the first mold K1 is indirectly cooled via the first insertion tube 6, the third insertion tube 8, and the second insertion tube 7, and the cooling fluid is not directly guided to the first mold K1, so that it is possible to prevent cracks due to rust corrosion of the first mold K1 and defects in the molded product due to the cooling fluid leaking into the molten metal caused by the cracks. In addition, the first" surface 11" is connected to the first surface 11 and the first' surface 11'.

Therefore, the first mold K1 is indirectly cooled via the first' insertion tube 6', the third' insertion tube 8', and the second' insertion tube 7', and the cooling fluid is not guided directly to the first mold K1. This makes it possible to prevent cracks due to corrosion by rust in the first mold K1 and defects in the molded product due to the cooling fluid leaking into the molten metal caused by the cracks.

[0060] In the embodiment of FIG. 20 described above, there is a first' long hole (not shown) that is linear from the fourth surface 14 to the third surface 13, a second' long hole (not shown) that is linear from the fourth surface 14 to the third surface 13, a third' long hole (not shown) that is linear from the fifth surface 15 or the sixth surface 16 to the inside of the first mold K1 and that communicates with the first' long hole (not shown) and the second' long hole (not shown), a first' insertion tube 6' that is inserted so as to abut against the first' long hole (not shown), a second' insertion tube 7' that is inserted so as to abut against the second' long hole (not shown), and a third' insertion tube 8' that is inserted so as to abut against the third' long hole (not shown). In the present invention, however, this is not limited to the above, and the first' long hole (not shown) may be formed in a straight line from the third surface 13 to the fourth surface 14, or in a straight line from the second surface 12 to the first surface 11, and the second' long hole (not shown) may be formed in a straight line from the third surface 13 to the fourth surface 14, or in a straight line from the second surface 12 to the first surface 11.

In this case, as in the above, the first' insertion tube 6' and the second' insertion tube 7' are connected to the third' insertion tube 8', and the cooling fluid from the first' insertion tube 6' is guided to the third' insertion tube 8' and the second' insertion tube 7' to cool the first mold K1. Therefore, the first mold K1 is indirectly cooled via the first' insertion tube 6', the third' insertion tube 8', and the second' insertion tube 7', and the cooling fluid is not guided directly to the first mold K1. This makes it possible to prevent cracks due to corrosion by rust in the first mold K1 and defects in the molded product due to the cooling fluid leaking into the molten metal caused by the cracks.
