Description

A kind of pulley with multiple grooves of making is cast the die for making core in loam core for groove
Technical field
The utility model relates to a kind of mould of making pulley with multiple grooves loam core, and specifically a kind of pulley with multiple grooves of making is cast the die for making core in loam core for groove.
Background technology
At present, there are two kinds of belt wheel casting channel process: a kind of belt wheel/dish loam core casting channel process that is scale is not used has been produced groove blank, and another kind is common belt wheel/dish slotless casting, and notch position is solid.
Pulley with multiple grooves/dish blank loam core casting channel process that existing not scale is used has two kinds:
The first: opposite opened (two) loam core casting channel process (piecing together containing four, six), independent loam core by two semicircles of the hollow of opposite opened Mold Making, before being filled into die cavity, must be combined into monoblock type loam core, two semicircle notch joints must be repaired, and the depth of parallelism of having proofreaied and correct cylindricity and notch just can be inserted die cavity and waits for cast molding.
The second: stacked loam core casting channel process, by single slot-die, make single slotted vane shape monoblock type hollow loam core.Press exterior mold design groove number, sheet loam core is inserted to die cavity layer by layer.Insert the front thickness that must check, revise every loam core, while inserting, need to adjust the depth of parallelism and the cylindricity in every loam core, effectively cast molding.
The loam core casting channel process reason that scale is not used of above two kinds of pulley with multiple grooves/dishes, is because of operations such as the repairing that needs to carry out loam core in actual production process, integration, adjustment, uses the phenomenons such as the notch that solves loam core is out of shape, reactor core is crooked.Cylindricity, axiality and the depth of parallelism of the larger loam core of diameter of foundry goods in die cavity is more difficult to resolve certainly.
Because the foundry goods with above two kinds of loam cores casting groove method is produced cannot meet the specification requirement of metalworking, without better mode, solve technique difficult point again at present, therefore in actual production manufacture process, most belt wheel/dish blank manufacturing firm all adopts the forging type of slotless blank to meet the specification requirement of metalworking.But this manufacture method waste is surprising.
Summary of the invention
The defect of making for above multiple-grooved loam core casting channel process, the utility model proposes a kind of mould in loam core for pulley with multiple grooves casting groove of making, the loam core that this mould is produced is monoblock type loam core, it has solved the extremely complicated difficult problem of multiple-grooved loam core moulding, can effectively control the depth of parallelism between the perpendicularity of loam core notch and axiality and groove, it is first placed on coremaking dish on collection mould bases, then in coremaking dish, place gang of cavities loose piece, pressing mold lid is put at loose piece center, pass through screw rod, nut is connected with collection mould bases central vertical, insert again core sand, put shaping lid, can be made into monoblock type loam core.
For reaching above object, the utility model has adopted following technical scheme: a kind of pulley with multiple grooves of making is cast the die for making core in loam core for groove, comprise collection mould bases, coremaking dish, gang of cavities loose piece, shaping lid, handle, described coremaking dish seat is located on collection mould bases, the external diameter of collection mould bases projection and the internal diameter of coremaking disk chassis fasten, described gang of cavities loose piece is some, be combined into annular, be fastened in the inner chamber of coremaking dish, the stupefied pressing mold lid that is provided with of gang of cavities loose piece internal diameter, before coremaking, pressing mold lid passes through screw rod, nut is connected (while getting core, separating) with collection mould bases, the described coremaking face of trying to get to the heart of a matter is provided with step, form groove with the external diameter of collection mould bases projection, gang of cavities loose piece inner circle waist and cylindrical base match with the external diameter of projection of collection mould bases and the groove that coremaking is tried to get to the heart of a matter on face respectively, on coremaking dish inwall, be vertically provided with protruding semicylinder, top is provided with shaping lid, shaping hd top face is provided with handle.
Gang of cavities loose piece described in the utility model is 4, is divided into two groups, and one group comprises relative short string piece, and another group comprises relative long-chord piece, and described short string piece is trapezoidal from outside to inside, and cylindrical chord length is shorter than inner circle chord length; Described long-chord piece inwall is inner concavity; Described handle is symmetricly set on locating straight of shaping hd top face; The utility model is also provided with boss and moves back template, and the height that described boss moves back template maintains an equal level mutually with the step that coremaking is tried to get to the heart of a matter on face.
Adopt after above technical scheme, the monoblock type loam core of the utility model made, not only operation is simple with it, to go production to have groove belt wheel, also possess that the notch depth of parallelism is good, external form cylindricity is good, axiality is good simultaneously, without pattern draft, advantage that bulk deformation amount is little, reach the specification requirement of metalworking completely, remove from the repairing in loam core and adjustment simultaneously.
