The purpose of this utility model is realized by following technical scheme:
A kind of core box of dual channel integral sand core comprises: quiet mould, dynamic model, the inside of quiet mould and dynamic model are respectively equipped with a large turbine runner die cavity, little turbine runner die cavity, and are respectively equipped with and penetrate Sha Kou on large turbine runner die cavity, little turbine runner die cavity; It is characterized in that: these quiet mould both sides respectively are equipped with a cylinder, and two cylinders are connected with the piece of taking out separately respectively; Be placed with several loose pieces on the tongue position of eddy current, quiet mould, the mutual correspondence of dynamic model snap together and form an one-piece core box.
Described take out on piece respectively be equipped with several be used for controlling height take out the piece baffle plate, and the both sides cylinder with take out the horizontal direction that piece is connected on, several limited blocks respectively are installed.
Described several loose piece is fixing by the core print location, location of a rectangle respectively.
The beneficial effects of the utility model: the utility model is owing to adopting technique scheme, and it first puts into several loose pieces in quiet mould in the coremaking process, and through matched moulds, penetrate sand, curing, upset and fall the operation process of sand; During die sinking, under the drive of cylinder, first both sides are taken out piece and extract out; After die sinking, ejecting the dual channel integral sand core, then take out core, then, more several loose pieces are taken out successively, just complete the coremaking process of a dual channel integral sand core; Not only save artificial core assembly operation process, improved the intensity of production efficiency and integral sand core; And, make core be difficult for producing distortion when molten iron is poured into a mould, guaranteed the dimensional accuracy of product.
