Through-hole is provided through inside and outside the lost foam pattern surface, which is characterized in that pottery is coaxially detachably installed in the through-hole
Porcelain tube, the ceramic tube both ends are sealed using resin sand, and the ceramic tube both ends are respectively and fixedly installed to the lost foam pattern
In molding sand in the molding sand of inner cavity and on the outside of lost foam pattern, sand removal mechanism, the sand removal mechanism are provided in the ceramic tube
Including the shaft being coaxially disposed with ceramic tube, the partially circumferentially spiral that the shaft is located at the ceramic tube inside is provided with leaf
Piece, described shaft one end reach the molding sand on the outside of ceramic tube and positioned at lost foam pattern and core box across the resin sand
In, the ceramic tube inside is filled with quartz sand.
In this way, ceramic tube can better high temperature resistant, resistance to deformation, expand with heat and contract with cold deflection for metal tube compared with
It is small, it can preferably be subjected to the high temperature of molten iron and wash away, can preferably guarantee the size in hole.At ceramic tube both ends, resin is set
Sand, central filler quartz sand can preferably improve the colleague of the intensity of ceramic tube, prevent molten iron from flowing into ceramic tube inside, keep away
Exempt from iron clamp sand in hole.It is provided with sand removal mechanism, in use, rotating shaft, will turn the direction axially adjacent to lost foam pattern center
It pushes, penetrates resin sand, then take molding sand out of lost foam pattern inner cavity using rotating vane, can preferably make in inner cavity
Molding sand loosen, facilitate sand removal.Present apparatus structure is simple, it is ensured that the quality in hole avoids burning into sand.
As optimization, one end that the shaft is located on the outside of the ceramic tube is vertically fixedly installed with turntable, the turntable
It is fixedly mounted in the molding sand between lost foam pattern and core box.
In this way, removing core box after the completion of casting, rotary turnplate facilitates sand removal to operate so that shaft rotates.
As optimization, the ceramic tube lateral surface is painted with cast paint.
In this way, the quality of elongated hole can be improved preferably.
As optimization, seal washer is provided between the ceramic tube peripheral surface and through hole wall.
Enter inner cavity in this way, can preferably avoid pouring molten iron.
As optimization, cooling device is provided on the outside of the core box.
In this way, can preferably cool down to core box, facilitate molding.
As optimization, the cooling device includes cooling water circulating pipe, and the cooling water circulating pipe ring-wound exists
On the outside of core box.
In this way, cooling water circulating pipe is arranged, structure is simple, easy to use.
In conclusion the utility model, which has, can preferably cast elongated hole, sand removal is convenient, and structure is simple, user
Just the advantages of.
