Abstract
The present invention is the understructure that a kind of suction pouring room promotes high temperature resistance, and casting interior due to suction is the container placed casting mold and establish vacuum state, and inhaling room under casting is the nearest part of distance high-temperature molten iron, under prolonged high-temperature baking, easily deforms desoldering.It will now inhale and cast the high temperature resistant iron casting molding of lower room, and cast out radial reinforcing rib in bottom, and load heat-barrier material in the space of each reinforcing rib, heating surface is greatly decreased, while improving non-deformability, and enable to inhale casting room long period steady operation.
Description
Technical field
Foundary industry anti-gravity pouring inhales the understructure of the raising high temperature resistance of casting room.
Background technique
Casting and forming has been important moulding technique in machine-building, and anti-gravity pouring has in foundry engieering
A kind of very moulding process of specific function.To such as thin-wall part, thickness, which differs greatly, etc. good mold-filling capacity, one
A little special dimensions are increasingly taken seriously.
The necessary condition of anti-gravity pouring is exactly that casting mold has under vacuum conditions, utilize external metallization liquid level and type
Intracavitary pressure difference, by the pressure of atmosphere by molten metal top push-in type chamber.Therefore, the suction that casting mold must be placed at and the external world seals
Casting is indoor, the sprue of type chamber be connected to stalk stalk stretch out inhale casting it is outdoor immerse downwards in molten metal absorption molten metal into
Enter type chamber.
It inhales casting room and is generally divided into upper layer and lower layer, upper layer is to inhale casting chamber cap, opens lid in order to place casting mold, lower layer is support
Disk is the bridge for playing connection function of casting mold and stalk installation.
Leafing molten metal is nearest under suction casting room, is often toasted by high-temperature liquid metal, the equipment especially produced in batches, inhales casting
Room lower layer is general to connect use with molten metal crucible, can only remove above crucible when repairing or replacing stalk.It inhales
Zhu Shi lower layer is welded with heat-resisting steels, is all easily deformed and is damaged by 1000 ° or more high-temperature bakings, plate and weld seam for a long time,
Making the sealing for inhaling casting room upper and lower level and sealing of a mould positioning, all often failure makes production be affected.
Summary of the invention
The present invention uses heat-resisting cast iron or heat resisting cast steel casting and forming, casts out radiation shape reinforcing rib in plane, anti-to improve
Thermal distortion forces, then it is laid with heat-barrier material in bottom, the room Shi Xizhu lower layer separates with high-temperature liquid metal, to reduce radiation and conduction heat
The influence of amount.
Radiation is cast out the technical scheme is that casting out using heat-resisting cast iron and in room, inhaling the bottom for casting lower room under suction casting room
Shape reinforcing rib loads heat-barrier material in each space of reinforcing rib, is installed with annular pressing plate by screw in the middle part of lower room and rise liquid
Pipe, stalk and suction cast plane between lower room and are lined with heat insulation sealing gasket piece.
Remarkable result of the invention is to inhale room under casting room to use heat-resisting cast iron casting and forming, without weld seam and light sheet structure
Part, small not easy to crack by temperature time variance shape, casting stalk is inhaled in installation can keep sealing, and the service life also extends, using a period of time, as long as
Stalk is replaced, inhales and casts lower room energy long period steady operation.

Specific embodiment
Suction pouring room promotes the lower cell structure of high temperature resistance, casts out room 1 under suction casting room using heat-resisting cast iron, casts inhaling
The bottom of room 1 under room is cast with radial reinforcing rib 8, heat-barrier material 5 is loaded in each space of reinforcing rib 8, in lower room 1
Portion's annular pressing plate 3 and the fixed stalk 2 of screw 4, stalk 2 and suction, which are cast, is lined with gasket seal 6 between lower room 1.
Claims (1)
1. suction pouring room promotes the lower cell structure of high temperature resistance, it is characterized in that: room under suction casting room is cast out using heat-resisting cast iron,
It inhales the casting bottom room Xia Shi and is cast with radial reinforcing rib, load heat-barrier material in each space of reinforcing rib, use ring in the middle part of lower room
Shape pressing plate is equipped with stalk by screw, and stalk and suction, which are cast, is lined with heat insulation sealing gasket between lower room.
