定させることが一般によく行われている。(Prior art) Conventionally, when casting a product using a die-casting machine, from the viewpoint of improving the quality of the product and preventing seizure, a mold release agent is applied to a spray device after the product is removed from the mold. It is common practice to stabilize the mold temperature of the mold by spraying the remolding surfaces of the fixed and movable molds that make up the mold upon activation.

々の設定温度に復帰させることが望ましい。(Problem 8 to be solved by the invention) Generally, the mold temperature of a mold is not uniform over the entire molding surface of both the fixed mold and the movable mold, and in reality,
Since there are temperature differences in each part depending on the shape of the remolding surface, that is, the shape of the product, the mold temperature at each part of the remolding surface of the fixed mold and movable mold lowered by the spraying of the mold release agent is lowered to the set temperature. Return time varies. On the other hand, from the perspective of improving the efficiency of casting cycle time,
When starting the next casting, it is desirable that the mold temperatures at each part of the remolding surfaces of the fixed mold and movable mold be returned to their respective set temperatures quickly and within a certain period of time.

復帰させることができない。However, in the spray device of the above-mentioned publication example, only one temperature sensor is provided to detect the mold temperature of the mold, and therefore, the mold release for the entire mold is performed based on the mold temperature of a specific area of the mold. Since only the spraying time of the agent is set, the mold temperature at each part of the remolding surfaces of the fixed mold and the movable mold cannot be returned to their respective set temperatures quickly and within a certain period of time.

ることは否めない。Therefore, by providing as many temperature sensors as the number of spray nozzles that spray the mold release agent, the mold temperature at each part of the remolding surface of the fixed mold and the movable mold can be individually detected. Based on the mold temperature of each part, the spraying time of the mold release agent from each spray nozzle can be individually set so that the mold temperature of each part of the remolding surface returns to its set temperature quickly and within a certain period of time. Conceivable. but,
In this case, it is undeniable that a large number of temperature sensors are required, and that the structure of mounting each of the temperature sensors to the mold becomes complicated.

However, it was discovered that the mold temperature of each part of the remolding surface has the characteristic of increasing and decreasing in proportion to the temperature of other temperature regions,
By taking appropriate measures to effectively utilize this mold temperature change characteristic, it is not necessary to attach a large number of temperature sensors to the mold, and each part of the remolding surface of the fixed mold and movable mold can be The objective is to quickly return the mold temperature to the set temperature within a certain period of time.

The temperature is compared with standard temperature distribution data set in advance by dividing each product into multiple temperature ranges, and if the mold temperature is higher than the temperature in the specified temperature range of the standard temperature distribution data, multiple sprays are Among the nozzles, the mold release agent spraying time of the spray nozzle corresponding to the above-mentioned specific temperature range is lengthened according to the temperature difference, and the mold release agent spraying time of the spray nozzle corresponding to other temperature ranges is increased in proportion to this temperature difference. On the other hand, if the mold temperature is lower than the temperature in the specific temperature range of the reference temperature distribution data, the mold release agent spraying time of the spray nozzle corresponding to the specific temperature range among the above spray nozzles is adjusted to the temperature difference. The release agent spray time of the spray nozzle corresponding to the other temperature ranges is controlled to be shortened accordingly, and in proportion to this temperature difference, the mold release agent spray time of the spray nozzle corresponding to the other temperature range is shortened. Therefore, it is not necessary to attach a large number of temperature sensors to the mold, and the mold temperature at each part of the molding surface of the mold can be quickly returned to each set temperature within a certain period of time.
