Edge be provided with the locating piece cooperated with locating slot.
Further technical scheme is, described locating slot is identical with the quantity of locating piece, and the quantity of described locating slot is
Four, four locating slots are evenly distributed on the edge below case lid, and four locating pieces are evenly distributed on above metal adventitia
On edge.
Further technical scheme is, the quantity of described rising head is four, and four rising heads are evenly distributed on resin sand
Core is on the circumference that the center of circle is formed
Further technical scheme is, described locating piece is fixedly mounted on metal adventitia by pin.
Further technical scheme is, described metal adventitia lower end is provided with reinforcement.
The technical program first passes through locating slot and locating piece are set, by locating slot and the cooperation of locating piece, at case
When lid and metal adventitia lid, case lid and metal adventitia are played positioning action, simultaneously by pin for being fixed by locating piece
And be positioned on metal adventitia, for protecting resin sand core to be not damaged by and being prone to, core is made by arranging case lid simultaneously
Type, finally by arranging rising head, rising head, for extracting after sand mold is pre-formed, rises and pours molten steel and top rough casting molten steel
Feeding effect in cooling procedure, has observation die cavity situation and the effect of aerofluxus simultaneously.
Compared with prior art, the beneficial effects of the utility model are:
After the metal die producing employing this utility model offer of high-temperature alloy furnace tube cone end blank, due to metal die
Chilling action, be conducive to boring the directional solidification of end blank, after core, cone end inner chamber and the allowance of cylindrical
Being effectively controlled, product yield is greatly improved, the product being machined into, and all reaches after performance detection and Non-Destructive Testing
The technology requirement of product and standard.In addition, the Metal mould material of selection is universal, low price, it is easy to reduces and produces into
This.
