欠点があった。Generally speaking, mold cooling for mold casting is done internally by drilling a cooling hole in the mold and pouring water or oil into it, or by spraying water or the like from the outside. An external cooling method was used, and the mold temperature was adjusted by adjusting the amount of water or oil. However, with the former internal cooling method, the adjustable range is rough, and depending on the part and mold shape, supercooling may exceed 7x.
j) In many cases, it could not be used, and as a result, the occurrence of galling, cracking, internal defects, etc. due to heating became a problem. On the other hand, in the latter cooling method, which sprays water from the outside, the spraying time and the time required to remove the water remaining on the split surface extend the cycle, and the water that cannot be completely removed becomes surface defects and internal defects, resulting in poor quality. The disadvantage is that it cannot be stabilized.

First, the switching valve 13 is opened by operating the timer 12, and water is allowed to flow from the branch pipe 5b to the cooling hole 4 of the lower mold 3. Next, after a predetermined period of time has elapsed, the p-switching valve 9 is opened by the operation of the timer 8, and the above procedure is carried out by adjusting the operating times of the timers 8 and 12. Then, when the timer 12 is stopped and the timer 8 is activated, the switching pulp 13 is closed and the switching pulp 9 is opened.As a result, only water flows from the branch pipe 5b to the cooling hole 4 of the lower mold 3. Since it is supplied, the mold can be rapidly cooled.

Both the switching pulp 9 and the switching valve 13 are in an open state, whereby water is sent from the branch pipe 5b and air is sent from the branch pipe 5C, and the water and air are mixed at the confluence section 5C and then flow into the cooling hole. 4, thereby making it possible to slowly cool the mold. Further, when the timer 8 is stopped and the timer 12 is activated, the switching pulp 9 is closed and the switching pulp 13 is opened, so that air is supplied to the cooling hole 4 only from the branch pipe 5a [7] Ru. Thereby, water in the cooling hole 4 can be removed, and cooling can be stopped at a predetermined temperature. Note that the operating times of the timers 8 and 12 may be set in consideration of the cavity shape, cooling position, etc.

奏するものである。In addition, in the above-mentioned embodiment, the case where water was used as the refrigerant was explained, but the refrigerant is not limited to water (of course, oil may also be used). [Effects of the Invention] As explained above, According to the mold fine adjustment cooling method according to the present invention, water (oil), air, or a mixture of water (oil) and air are used as the medium for cooling the mold, and each of them is time-controlled. This makes it possible to finely adjust the mold temperature. With this trap, it is possible to easily cool the required cooling position of the mold, which was difficult in the past, and the cycle lengthening due to external cooling etc. is eliminated, and the operating rate can be improved. Furthermore, by being able to adequately control the mold temperature, quality stability can be ensured, thereby reducing the defective rate. Furthermore, conventionally excessive cooling has given the mold a large thermal amplitude, but since this can be reduced, the life of the mold can be extended, which brings about various effects.
