Title:
MOLDING MACHINE AND SPRAYING DEVICE
Document Type and Number:
Japanese Patent JP2023073623
Kind Code:
A
Abstract:
To provide a molding machine capable of improving precision in the control of a mold temperature.SOLUTION: A die cast machine 1 repeats a molding cycle MC and comprises: a machine body 3; a cooling part 13; and a control device 5. The machine body 3 performs mold closing, injection and mold opening in each molding cycle in order. The cooling part 13 cools a mold 101 in each molding cycle. The control device 5 controls the cooling part 13 based on a signal from a temperature sensor 59 detecting the temperature of the mold 101. The cooling part 13 comprises a spraying device 15 performing spraying toward the mold 101 before mold closing in each molding cycle. The control device 5 controls the operation of the cooling part 13 based on a temperature difference between a first temperature D1 detected by the temperature sensor 59 before spraying and a second temperature D2 detected by the temperature sensor 59 after spraying in the molding cycle in which the first temperature D1 was detected.SELECTED DRAWING: Figure 1
