The number of described loose piece is 2, and the axis along dip mold inner ring is symmetrical, at the not crossbeam position of easy-formation of salt core, on Design of Dies, adopt loose piece structure, in the time of the depanning of salt core, one, loose piece and salt core are ejected, and after earth pressure release, loose piece are taken off again, and have successfully solved the problem rupturing after the depanning that such special-shaped salt core causes because of density unevenness.
Described dip mold inner ring is provided with the loose piece all-moving surface of the process mirror finish processing corresponding with loose piece, and to ensure that loose piece can be ejected with salt core smoothly, and loose piece does not move up under pressure.
The angle of described loose piece all-moving surface and plumb line place plane is 10 °.
Between described dip mold inner ring and described top die, be connected with dismountable the first alignment pin that prevents that both from relatively rotating or horizontally slipping.
Utilize above-mentioned cross beam type salt core compacting tool set, the utility model also provide a kind of salt core its be the salt core of being manufactured by salt core compacting tool set described in above-mentioned any one, this salt core is cross beam type shape.
The beneficial effects of the utility model are:
1 Design of Dies adopts control with changed scale cavity structure, salt core easy-formation position adopt 1:(1+0.7) mold cavity volume ratio, and adopt 1:(1+0.8 at the weaker easily broken position of salt core) mold cavity volume ratio, in the time of compacting, increase the intensity at the easily broken position of salt core, reduced salt core compacting percent defective.
Mold cavity volume automatic ration for 2 salt adding amounts, without weighing, can realize the moulding of salt core pressing one-time, has saved forming cutter manufacturing procedure, and pressing pressure is 13～15MPa, can accurately ensure salt core height, has reduced energy resource consumption.
3 at the salt core crossbeam position that easy-formation is not difficult to depanning, on Design of Dies, adopt loose piece structure, loose piece all-moving surface adopts mirror finish processing, to ensure that loose piece can be ejected with salt core smoothly, and loose piece does not move up under pressure, in the time of the depanning of salt core, one, loose piece and salt core are ejected, after earth pressure release, again loose piece is taken off, successfully solved the problem rupturing after the depanning that such special-shaped salt core causes because of density unevenness.
