系統１ＩＩＪ ｌをしている。(Conventional technology) In light alloy die casting, synthetic resin injection molding, etc., if the mold temperature is low, wrinkles will occur, and if it is too high, it will cause seizing, galling, etc., so the mold temperature is low. When the mold temperature changes, it is necessary to quickly raise the temperature (by heating, and when the temperature is high, use powerful cooling to lower the temperature. Therefore, conventionally, (1) the amount of cooling medium such as cooling water is controlled according to changes in mold temperature) (2) If the temperature is low, use the heating system; if the temperature is high, use the cooling system.

る。(Problems to be Solved by the Invention) However, the method (1) of controlling the cooling medium portion has the following problems. In other words, if the amount of cooling medium is reduced when the mold temperature is low, there will be areas where the cooling medium does not circulate, resulting in localized overheating areas that will cause product defects such as seizure and galling, and even cause the mold to deteriorate. There is also a possibility of damage.

どの問題点がある。If the number of cooling passages is reduced to prevent the above problem, the amount of cooling medium will be insufficient when the mold temperature is high, resulting in insufficient cooling capacity, requiring external cooling, and reducing cycle time (cooling circulation). In addition, the two-system control method (2) above has a heating system in addition to the cooling system, which increases costs, complicates control, and requires dangerous work to handle high-temperature heating media. It is very difficult to provide passages for two systems, one for the cooling system and one for the heating system, in the same mold due to space constraints, and there are problems such as that one or both of them may be insufficient.

する。Next, a method of controlling the temperature of the mold using the temperature control I8 configured as described above will be explained. In this embodiment, the regulating valve 11 is adjusted to control the discharge amount in proportion to the temperature difference within a predetermined temperature range, and is fully closed (flow rate 0) below that range.
Therefore, it should be adjusted so that anything above that range will be heard. When the temperature of the mold 1 is lower than the above temperature range, the temperature of the discharged cooling water is detected and the regulating valve 11 is fully opened, and all the discharged cooling water is supplied via the piping 14 to the primary side of the i[9]. It is returned to the mold 1 and circulates within the mold 1. Since the temperature of the cooling water is higher on the discharge side than on the supply side, as the cooling water circulates, the temperature of the cooling water increases and the M4 of the mold 1 is accelerated. According to this method, cooling water is supplied m
Since a constant current is always supplied without reducing the amount of water, even if there is a cooling passage 2a with a large piping resistance above the mold 1, sufficient cooling water can be supplied. If the temperature of the mold 1 becomes too high, the temperature on the first outlet side of the cooling water also exceeds the predetermined temperature range, and the regulating valve 1
1 is closed, and all the cooling water supplied through the pipe 13 is discharged. As a result, the mold 1 is supplied with low-temperature cooling water from the supply source 7, making it possible to lower the temperature of the mold 1 to an appropriate range more quickly. Adjustment valve 11
In the middle between fully open and fully open, some of the coolant that is discharged is circulated due to the temperature, and it works to bring the engine to a parallel state more quickly.
別の実施例としては、排出された冷却水の一定の温度を
基準として、仝閉と全開を切り換えるようにすることも
できる。As another example, it is also possible to switch between closed and fully opened based on a constant temperature of the discharged cooling water.

When necessary, the temperature control method returns and circulates the discharged cooling medium to the primary side of the supply device according to the temperature, and the 5A setting makes it possible to sufficiently cool and heat the mold with a simple configuration. Become. In other words, when the mold temperature is low, it is possible to raise the temperature of the mold more quickly,
Moreover, local heating due to lack of cooling medium does not occur.
