  • Patent number: 9186722
    Abstract: Provided is a tilt type gravity molding device which requires no riser, prevents increase in length of a sprue runner, suppresses occurrence of clogging of a molten metal, and facilitates temperature control of the molten metal. The tilt type gravity molding device includes: a mold having defined therein a product forming space for forming a molded product, and configured to receive a molten metal from a pouring gate; a ladle including: a storing section capable of storing the molten metal therein; and a plate-like opening/closing body abutting on the mold, and having an injection port capable of being aligned with the pouring gate; and a gas supplying section for supply gas into the product forming space. The ladle is slidably mounted to the mold, and is slidable between an opening state in which the injection port is aligned with the pouring gate, and a closing state in which the plate-like opening/closing body closes the pouring gate.

  • Publication number: 20120325424
    Abstract: To eliminate the need for a riser and for reduction in tilt speed and to enable molten metal contained in a mold to be pressurized by gas appropriately, a tilt type gravity molding device including a mold which can tilt between a fallen position and a standing position raised approximately 90 degrees from the fallen position, a pouring gate mold in which a pouring gate guiding the molten metal to a cavity of a molded article is formed, and a bowl-like member which stores the molten metal and pours the molten metal into the pouring gate in accordance with tilt of the mold includes closing means which is provided between the pouring gate and the cavity and can open and close the pouring gate, a gas inlet 9 which is provided at an upper portion of the mold at the standing position, prevents the molten metal from flowing out of the mold, and allows only gas to pass therethrough, and gas supplying means which allows high-pressure gas to be supplied to the gas inlet.
