Title:
MOLDING MACHINE AND SPRAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/090262
Kind Code:
A1
Abstract:
A die casting machine 1 repeats a molding cycle MC, and has a machine body 3, a cooling unit 13, and a control device 5. The machine body 3 performs mold closing, injection, and mold opening in each molding cycle in sequence. The cooling unit 13 cools a die 101 in each molding cycle. The control device 5 controls the cooling unit 13 on the basis of a signal from a temperature sensor 59 for detecting the temperature of the die 101. The cooling unit 13 includes a spray device 15 for spraying toward the die 101 before mold closing in each molding cycle. The control device 5 controls the operation of the cooling unit 13 on the basis of the temperature difference between a first temperature D1 detected by the temperature sensor 59 before the spraying and a second temperature D2 detected by the temperature sensor 59 after the spraying in the molding cycle in which the first temperature D1 was detected.
