The utility model has the advantages of easy in fabrication technology of the die, low cost, convenient operation, reposeful die and high accuracy of the died product.

Description

The smart casting of integral turbine die mould metal block horizontally taking type mould apparatus

The utility model relates to a kind of no surplus precision casting mold, the smart casting of particularly a kind of integral turbine die mould metal block horizontally taking type mould apparatus.

The turbine product is because its blade has " distortion " in various degree, and the movable block that then relates to the essence casting die mould of blade-section moulding can not be along conplane a certain direction removing from mould.Usually the loose piece that adopts soluble material to make at home is as the urea loose piece.The spiral mould apparatus of employing that America and Europe etc. are state-owned.Above-mentioned two kinds of methods all are based on the certain methods that the metal movable block can not the horizontally taking type removing from mould be done something against one's will.These methods part that all comes with some shortcomings.Adopt the urea movable block, the one, can not guarantee required precision; The 2nd, had more the operation of dissolving the urea movable block together undoubtedly again.As for spiral mould apparatus,, with regard to manufacturing process, increased difficulty undoubtedly because the removing from mould track of its movable block is a helical curve rather than a simple straight line.In addition, this device must design corresponding servicing unit, and then the manufacturing cost of die mould can increase greatly.

The purpose of this utility model is to design a kind of easy device that is applicable to block cast turbine die mould metal block removing from mould to simplify the die mould manufacturing process, is convenient to press the operation of wax operation, reduces the die mould manufacturing cost.

The purpose of this utility model is achieved through the following technical solutions: the smart casting of a kind of integral turbine die mould metal block horizontally taking type mould apparatus, it comprises the die mould die bed, it is characterized in that on die bed, having a ring shaped slot, be evenly equipped with and inserting that the turbo blade number equates at cannelure, the upper surface of inserting is the plane that the adjacent in twos exhaust limit of turbo blade forms, on inserting, have gathering sill, on inserting, be evenly equipped with the movable block that equates with the number of inserting, the bottom end face of this movable block overlaps with the upper surface of inserting, be provided with the guide finger that movable block is moved in the upper edge gathering sill direction of inserting in the bottom of movable block, the two sides shape of the movable block two sides shape with turbo blade respectively is identical, and corresponding two sides is a male and female face.

The utility model compared with prior art, its remarkable advantage is: the utility model is a horizontally taking type, and the horizontally taking type device is a kind of easy device, thereby the technology difficulty that die mould is made is little, also need not other auxiliary mould apparatus, corresponding die mould casting cost just can reduce greatly.The horizontally taking type device also is convenient to operation, and in addition along the gathering sill operation, then the loose piece removing from mould is more steady smoothly.This loose piece can guarantee high-precision requirement owing to be that metal is made.

The utility model is described in further detail below in conjunction with drawings and Examples:

Fig. 1 is a die bed part section structural representation.

Fig. 2 is the plan structure schematic diagram of inserting.

Fig. 3 is the cross-sectional view of inserting.

Fig. 4 is the movable block structural representation.

Fig. 5 is the movable block cross-sectional view.

Fig. 6 is the utility model fit structure schematic diagram.

Embodiment: design a die mould die bed 1, have a ring shaped slot 2 that has a tapering on the die bed 1.Design some (identical) and insert 3, be distributed in the cannelure 2 with the number of blade.3 upper surfaces of inserting are the plane that the adjacent in twos exhaust limit of turbo blade forms, and two outline lines, two the exhaust limits adjacent in twos with turbo blade of 3 the upper surface of inserting coincide.Insert and have gathering sill 4 on 3.Design some movable blocks 5, the bottom end face of movable block 5 is identical with 3 the upper surface of inserting.Movable block 5 bottoms have guide pin hole, and the direction operation of the movable block 5 of guide finger 6 at the upper edge gathering sill 4 of inserting is housed, and can guarantee that movable block is along the optimum orientation removing from mould.Die bed 1, insert 3, the assembly relation of major part such as movable block 5 can always scheme referring to die mould.
