Abstract: The present invention relates to a casting die device and a casting method used to obtain a cast product in which an inner bore, at least one end of which is open, is formed. The casting die device has a core pin for forming the inner bore in the cast product, and a vibration-transmitting member for transmitting vibrations from a vibrator of a micro-vibration machine to the core pin. When casting is being performed, vibrations from the vibrator are imparted to the core pin by way of the vibration-transmitting member. The vibrations also propagate to sites surrounding the core pin, in molten metal that has been poured into a cavity.

Abstract: A casting die device and a casting method. The casting die device has a core pin for forming an inner hole in a casted article. The core pin is a hollow body, and a pressurizing pin is inserted into a hollow inner part of the core pin. Vibrations from a vibrator of a micro vibration machine are imparted to the pressurizing pin via a vibration transmission member. The vibrations further propagate to the core pin from the pressurizing pin, and then propagate to the area surrounding the core pin in a molten metal that has been poured into a cavity.

Abstract: A squeeze pin circuit is installed to a direction switching valve. The direction switching valve is configured to switch a direction of hydraulic pressure to a core cylinder. The squeeze pin circuit is configured to drive a squeeze pin. The squeeze pin is configured to partially pressurize molten metal filled in a cavity. The squeeze pin circuit includes a squeeze pin cylinder and a flow rate adjusting unit. The squeeze pin cylinder is coupled to the direction switching valve to drive the squeeze pin. The flow rate adjusting unit is installed on a hydraulic pressure path. The hydraulic pressure path couples the direction switching valve to a head side of the squeeze pin cylinder. The flow rate adjusting unit is configured to ensure pressure compensation and temperature compensation.

Abstract: In a method for applying a powder state mold lubricant onto a die-casting mold, a movable mother die and a stationary mother die are clamped to define a mold cavity with a movable insert die and a stationary insert die, in which a plunger tip slidably arranged within a sleeve opens a molten material supply hole, and communication between the sleeve and the mold cavity is blocked. A pressure within the mold cavity is reduced by opening a powder suction passage opening into the mold cavity and establishing communication between a powder discharge passage communicated with a powder storage source and a molten material supply passage opening to the mold cavity. The powder state mold lubricant is directly within the powder storage source into the mold cavity via the molten material supply passage for applying the powder state mold lubricant on the mold surface of the mold cavity.

Abstract: An application method of a powder mold lubricant for a vacuum die-casting mold can effectively apply the powder mold lubricant onto a mold surface of the mold cavity with supplying the powder mold lubricant in small amount, can avoid liquefying of the power mold lubricant to degrade quality of a product, and can avoid loss in cycle time in a vacuum die-casting operation.
