造装置。[Claims for Utility Model Registration] 1. A device base 1 for heating and melting the cast metal in a swingably held crucible 12 with a gas burner in the atmosphere, and on which this melting part is placed.
1. A small precision pressure casting device for pouring the molten metal under pressure into a mold hermetically sealed with air or inert gas, characterized by having the following structural requirements. (A) Holds a boat-shaped crucible horizontally, has a heating window 16 for blowing a gas flame onto the crucible from the outside, and a pouring hole 28A facing the sprue 12H of the crucible, and horizontally on the device base. A cylindrical melting chamber 13 is provided which is pivotally supported so as to be swingable, and after the metal in the crucible is completely melted, the melting chamber is swung at a predetermined angle α to invert the crucible held vertically with its sprue facing down. A rocking melting section 22 in which a rocking lever mechanism 20 and a pressurizing operation rod 34 for operating a pressurized gas introduction mechanism 26 when the melting chamber swings are integrally provided in the melting chamber. (a) A sealing member 32 that slidably engages with the melting chamber is provided on the periphery of the melting chamber via the device base, and when the melting chamber is swung by a predetermined angle by the sealing member,
A melting process that forms a closing part 43 that seals the heating window and airtightly connects the melting chamber melting hole 28A to the melting hole 28B provided in the sealing member and the base portion melting hole 28C. A room air sealing section 24 and a pressurized gas introduction mechanism operated by the pressurizing operation rod of the oscillating melting section are provided, and an introduction hole 46 for air or inert gas introduced by this mechanism is provided. Pressure pouring part 23 communicates with the pouring hole of the hermetically sealed part of the melting chamber. 2 Enlarge the swinging angle of the swinging melting part by the required angle δ,
In addition to the three-step operation of heating, pouring, and pressurizing,
2. The compact precision pressure casting apparatus according to claim 1, wherein during pressurization immediately after pouring the molten metal, the molten metal pouring hole in the base body is hermetically closed and sealed by the sealing member and the melting chamber outer circumferential wall 33.
