Claims

[Scope of Claim for Utility Model Registration] 1. An airtight chamber body 1 for melting and casting, a lid body 2 that covers the upper end opening of the airtight chamber body 1 so as to be openable and closable, and approximately the lower half inside the airtight chamber body 1. A heating device 4 which is equipped in a section and holds a melting crucible 3 so as to be freely inserted and removed from above, an upper end of the heating device 4, and the lid 2.
A mold 5 held between the mold 5, a pressurized gas injection means 6 for pressurizing the inside of the airtight chamber body 1 and the mold 5 from the mouth 51 side, and an upper bottom portion 52 of the mold 5.
The mold 5 passes through a conduit 21 formed in the lid body 2.
A vacuum pressure casting machine comprising a depressurizing means 7 for suctioning and depressurizing the inside, and an inverting means 8 for inverting the airtight chamber main body 1. 2 The pressurized gas injection means 6 is connected to the delay relay 63
, 64, and is adapted to operate with a certain delay after the airtight chamber main body 1 is reversed in accordance with the properties of the melted material. 3. The reversing means 8 includes a horizontal rotating shaft 81 fixed to the outside of the airtight chamber body 1, and an operating handle 84 connected to the base end of the rotating shaft 81 via gears 82, 83. , the operating handle 84 is rotated 90
By rotating the airtight chamber body 1 180°
The casting machine according to claim 1, which is a utility model and is adapted to be reversed. 4 The upper end of the heating device 4 has a communication hole 41 in the center.
A connecting plate 41 having a diameter of 1 is placed on the lower end of the mold 5, and a communicating hole 531 is provided at the center of the mold 5.
Ventilation slot 532 for centrifugal pressurization connected to 1
A mold receiving plate 53 having the above-mentioned communication hole 4 is provided.
The upper end locking collar 3 of the melting crucible 3 is attached to the periphery of the melting crucible 3.
1 is locked, and the connecting plate 41 and mold receiving plate 53 are joined together to connect and hold the heating device 4 and the mold 5 vertically within the airtight chamber main body 1, thereby making the crucible 3 and the mold 5 coaxial. Scope of claims for utility model registration that maintains consistency
Casting machine described in section.
