Title:
VERTICAL SEPARATION-TYPE HYDRAULIC TILT POUR CASTING MACHINE, AND TILT POUR CASTING METHOD
Document Type and Number:
WIPO Patent Application WO/2022/119005
Kind Code:
A1
Abstract:
The present invention relates to a vertical separation-type hydraulic tilt pour casting machine, and a tilt pour casting method using same. More specifically, a feeder is formed in a die that is separated into an upper die and a lower die, and the feeder can be pressurized by a hydraulic device to manufacture a cast product having little variation in quality without the need for compensation due to the contraction of molten metal. According to an embodiment of the present invention, provided is a vertical separation-type hydraulic tilt pour casting machine characterized by comprising: a tilt pouring device that tilts a tilt pour casting die at a certain speed so as to inject molten metal into a cavity; and a pressurizing device for pressurizing the feeder. The pressurizing device includes: a feeder cover formed to accommodate the outer circumferential surface of the feeder of the tilt pour casting die and fixed to the tilt pour casting die to form a certain sealed space that includes the feeder; and a piston that is accommodated inside the feeder cover and pressurizes the feeder inside the sealed space formed by fixing the feeder cover to the tilt pour casting die. The machine further includes a hydraulic device which removes an injection cup after injecting the molten metal into the cavity by driving the tilt pouring device, and which is controlled so that the feeder is pressurized with the piston after the feed cover is fixed to the tilt pour casting die so as to accommodate the feeder, wherein the hydraulic device applies pressure to the feeder cover and the piston. The pressure applied to the molten metal by the piston is greater than the pressure applied to the tilt pour casting die by the feeder cover.
