Abstract
The utility model relates to a sand box of disappearance model sand cover half, the utility model aims to provide a gentlier, easily make, be convenient for the adjustment full mold sand box. Including the cope body, sand box body bottom surface sets up bleed -off passage, the outside vacuum exhaust tube of bleed -off passage intercommunication sand box along long limit, through horizontal exhaust tube intercommunication, set up the aspirating hole that supplies to take out the air in the molding sand on the horizontal exhaust tube pipe wall between the bleed -off passage, still set up vertical exhaust tube on the bleed -off passage, the axial vertical of vertical exhaust tube sets up the aspirating hole that supplies to take out the air in the molding sand in the inside bottom surface of sand box body on the vertical exhaust tube pipe wall. The utility model discloses lead to a full mold sand box and through setting up bleed -off passage, horizontal exhaust tube and vertical exhaust tube in that the sand box is inside, can reform transform the demand of bleeding of the different products of easy adaptation in a flexible way to the sand box, simultaneously greatly reduced the manufacturing cost of sand box to whole sand box can its quality of greatly reduced when reaching the operation requirement.
Description
Technical field
This utility model is related to a kind of evaporative pattern sandbox, and in particular to a kind of sandbox for evaporative pattern molding sand cover half.
Background technology
Technology of EPC is that casting dimension shape similar foam type bonding is combined into model cluster, brushes fire resisting and applies
After material drying, vibration molding in dry sand is embedded in, cast under negative pressure makes model gasify, liquefaction metal replacement bubbles model position
Put, obtain and bubbles model identical metal casting after molten metal cooling.
In prior art, when the sandbox for containing molding sand usually utilizes casting method with the vanishing pattern casting workpiece, need to use
To dispellable mould casting sandbox.Existing sandbox mostly is five facing sand casees of rectangular shape, including internal layer and the double-deck knot of outer layer
Structure, is formed pumping cavity, has aspirating hole, in consolidation molding sand, taken out by the level of outer layer on inner layer wall between internal layer and outer layer
Trachea carries out evacuation by cavity is evacuated.But this kind of sandbox weight is big, is not easy to carry out pumping adjustment according to concrete model.
Utility model content
Main purpose of the present utility model is to provide a kind of lighter, easily fabricated, evaporative pattern sandbox for being conveniently adjusted.
For achieving the above object, the technical solution adopted in the utility model is：A kind of evaporative pattern sandbox, including sandbox sheet
Body, described sandbox body are the rectangular box body of opened upper end, and the sandbox body bottom surface arranges interior empty pumping along long side
Passage, the bleed-off passage lead to the vacuum exhaust pipe outside logical sandbox；By being arranged at sandbox sheet between the bleed-off passage
Horizontal exhaust tube connection in body inner bottom surface, arranges the pumping for extracting the air in molding sand out on the level pumping tube wall
Hole；Also set up vertical exhaust tube on the bleed-off passage, vertical exhaust tube is axially perpendicular to sandbox body interior bottom surface, vertically
Aspirating hole for extracting the air in molding sand out is set on pumping tube wall.
Further, described vertical exhaust tube is four, is arranged on the corner of sandbox body interior bottom surface, described to take out
Trachea top mouth of pipe cover seal, the mouthpiece cover are fixed on sandbox body interior side.
Further, this side outer wall top of described sandbox is provided with main reinforcing ring, and the main reinforcing ring is straight-flanked ring
Arrange around four side walls of sandbox main body, main reinforcing ring cross section is straight-flanked ring.
Further, described main reinforcing ring is provided for hanging the main box handle of sandbox with respect to both sides centre position.
Further, this side outer wall bottom of the sandbox be provided with auxiliary box ring described in main reinforcing ring surround for straight-flanked ring
Four side walls of sandbox main body are arranged, and main reinforcing ring cross section is straight-flanked ring.
Further, the auxiliary reinforcing ring is each with respect on both sides arranges two auxiliary boxes for being used for hanging and stirring sandbox
Described two auxiliary boxes are the center line with regard to the additional strong ring side symmetrical.
This utility model leads to a kind of evaporative pattern sandbox by arranging bleed-off passage, horizontal exhaust tube and vertically inside the sandbox
Exhaust tube, flexibly can carry out transforming the pumping demand for easily adapting to different product to sandbox, while greatly reducing the system of sandbox
This is caused, and whole sandbox can substantially reduce its quality while use requirement is reached.
