Description of drawings
Fig. 1 is an overall structure schematic diagram of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As shown in the figure: crucible 12 is set on smelting furnace 13, and the opening part of crucible 12 is coated with sealed crucible lid 9, and it is provided with intake valve 10 with the inner space sealing of crucible 12 on crucible 12, can fill shape, pressurize and exhaust thus.Sealed crucible lid 9 is provided with stalk 8, these stalk 8 lower ending openings see through sealed crucible lid 9 and insert in the crucible 12, crucible cover 9 tops are provided with the vacuum (-tight) housing 3 of sealing, be provided with pressing mold frame 6 in the vacuum (-tight) housing 3, casting pattern 7 is installed on the pressing mold frame 6, stalk 8 upper end open are positioned at vacuum (-tight) housing 3 and match with casting pattern 7, and vacuum (-tight) housing 3 is connected with lowering or hoisting gear 1, are provided with the vacuum pumping valve 4 and vacuum-breaking valve 2 of its inner space of control on vacuum (-tight) housing 3.
Vacuum (-tight) housing 3 is provided with vacuum, pressure, the vacuum contact table 14 with temperature, the pressure contact table 15 and temperature contact table 16 of surveying its inner space, casting pattern 7 opening part buckle closures have air permeable plate 19, thermo detector 17 on the sealed crucible lid 9, the inner space of crucible 12 is inserted in the inner of this thermo detector 17, be provided with air bleeding valve 20 on sealed crucible lid 9, vacuum (-tight) housing 3 is provided with air bleeding valve 5.Lowering or hoisting gear 1 is arranged on the frame 18 of vacuum (-tight) housing 3 tops.Casting pattern 7 bottom surfaces are provided with casting gate, and the casting cavity in the casting pattern 7 is communicated with casting gate, vacuum (-tight) housing 3 inner spaces, and stalk 8 upper end open are connected with this casting gate.To having pipe bending cylinder 21, the piston rod end of pipe bending cylinder 21 is provided with limiting plate 22 on the pressing mold frame 6 directly over the casting pattern 7, and this limiting plate 22 is high up in the air to be arranged on position directly over the air permeable plate 19.
