Abstract
The invention discloses a combined knockout core structural investment pattern die bundling core, comprising a positioning mandrel, a drawing flap, a mould flap, a cramping device and a terminal base.The core is divided into nine flaps whose contact sides are parallel along the axial direction of the mould knockout core according to the mode of the Chinese character of ''Jing'', wherein the four cut surface rectangle flaps at the axial center are positioning mandrel, three cut surface flaps are drawing flaps and two cut surface flaps are mould flaps. The bundling solid core combined by nine flaps participates the investment pattern forming by inserting into the die, and draws out the positioning mandrel, the drawing flap and mould flap in turn during knockout. The combined knockout core structural investment pattern die bundling core avoids the welding procedure for the special form products in batch production by drawing the core in sequence, thus achieving the consistent dimension, high efficiency and low cost.
Description
Technical field
The present invention relates to the compacting tool set of fusible pattern, specifically be meant,, be used for the loose core investment pattern die bundling core of structure of a kind of combined type on the mould of fusible pattern injection in the operation section of prefabricated fusible pattern with in the model casting stainless steel automobile tail gas discharging conversion seat goods.
Background technology
Model casting claims " lost-wax casting " again, normally coat several layers by zircon sand, zirconium English powder, the formulated high temperature resistant ventilative refractory material of Ludox on the fusible pattern surface of wax system, after treating its dry through, molten the going of the fusible pattern of wax system wherein made shell, shell is strengthened through roasting, again to the investment shell intracavity casting molten metal, after liquid cooling fusion is coagulated, remove the method for shell acquisition metal casting goods, because the foundry goods goods that obtain have high dimension precision and surface smoothness, so be called " precision-investment casting " again.First procedure that model casting is produced is a fusible pattern of making goods, and fusible pattern injects pasty state wax mould material with the piston pressurization making die for molding of fusible pattern usually.For the thread a pipe goods fusible pattern of special-shaped feature of big outer fine taper, S shape or spirality in having more, because of its demoulding of can't loosing core, prior art adopts welding to solve more, promptly uses laminar flatiron, can't loose core the demoulding and the connecting portion melting of the fusible pattern made respectively together.Welding is difficult to guarantee the uniformity of foundry goods goods morpheme size in batch process, easy slag inclusion, and production efficiency is low, recruitment cost height, therefore, prior art exists influences the uniformity of foundry goods goods morpheme size and the problems and shortcomings that efficient is low, cost is high.
Summary of the invention
Problems and shortcomings at above-mentioned prior art existence, the present invention take along core loose core axially, by " well " font core is divided into nine lobe bars that are in contact with one another parallel sided, wherein, four cut surface rectangle lobe bars that are positioned at the axle center are positioning core axle, three cut surface lobe bars are for taking out type lobe bar, two cut surface lobe bars are type lobe bar, boundling entity core by these nine lobe bar combinations, insert the moulding that participates in fusible pattern in the mould, extract positioning core axle during the demoulding successively out, take out type lobe bar, the technical scheme of type lobe bar, the investment pattern die bundling core that provides a kind of combined type to loose core structure is intended to by loosing core successively respectively, makes the batch process of special-shaped feature goods fusible pattern, exempt welding sequence, reach consistent size, the efficient height, the purpose that cost is low.
The object of the present invention is achieved like this: the loose core investment pattern die bundling core of structure of combined type, comprise positioning core axle, take out type lobe bar, type lobe bar, banding device, end seat, wherein: described positioning core axle is in the core of being cut apart by " well " font, be positioned at the core axle center, section is the lobe bar of rectangle, upper edge, four face centers axis direction respectively is provided with the guide rail of a projection, and lobe bar tail end center is provided with fixedly blind screwhole; The described type lobe bar of taking out is in the core of being cut apart by " well " font, be positioned at the four sides of positioning core axle, lobe bar with three cut surfaces and a profile is provided with a recessed guide groove with upper edge, the contact-making surface center axis direction of positioning core axle, and lobe bar tail end center is provided with fixedly blind screwhole; Described type lobe bar is clipped in two adjacent smoking between the type lobe bar in the core of being cut apart by " well " font, has the lobe bar of two cut surfaces and a profile, and the tail end center is provided with fixedly blind screwhole; Described banding device is a cylinder open annular member, and opening part is provided with lock ring screw and screw, is placed in the core afterbody of being cut apart by " well " font.Described end seat is for being positioned at the short cylindrical shape member of the core tail end of being cut apart by " well " font, and end face is provided with the round tube hole that cooperates with each lobe bar tail end blind screwhole.
Each member mutual alignment and relation
During boundling, positioning core axle is positioned at the center, each lobe bar is centered around the periphery of positioning core axle by numbering, the guide rail at positioning core axle four sides slides and embeds the corresponding guide groove of taking out type lobe bar, the end seat is fixed on each lobe bar tail end by screw and constitutes the boundling core on its end face, the banding device is inserted in the afterbody of boundling core, by screw with boundling core banding.
Operation principle
During fusible pattern moulding, the boundling core inserts the moulding that participates in fusible pattern in the investment pattern die; During the fusible pattern demoulding, unclamp the screw of end seat earlier, the screw of backing out the banding device again takes off the banding device, extract positioning core axle successively out, take out type lobe bar, type lobe bar, after positioning core axle is extracted out, reserve a circuitous space of loosing core at boundling core center, as long as will be wherein one takes out the type lobe bar suction downwards earlier space of loosing core, extracts out backward along the space of loosing core, at this moment again, whole boundling core just begins to become flexible, circuitous more as stated above extract out one or two take out type lobe bar after, the remaining lobe bar of boundling core just begins " to subside " to the axle center and compiles, and the lobe bar of remainder is directly extracted out to get final product again, then remove the somatotype shell of investment pattern die again, take out the fusible pattern goods.
Above-mentioned, the present invention take along core loose core axially, by " well " font core is divided into nine lobe bars that are in contact with one another parallel sided, wherein, four cut surface rectangle lobe bars that are positioned at the axle center are positioning core axle, three cut surface lobe bars are for taking out type lobe bar, two cut surface lobe bars are type lobe bar, boundling entity core by these nine lobe bar combinations, insert the moulding that participates in fusible pattern in the mould, extract positioning core axle during the demoulding successively out, take out type lobe bar, the technical scheme of type lobe bar overcomes the problems and shortcomings that prior art exists, the loose core investment pattern die bundling core of structure of a kind of combined type that is provided, by loosing core successively respectively, make the batch process of special-shaped feature goods fusible pattern, exempted welding sequence, reached consistent size, the efficient height, the purpose that cost is low.
