Abstract
The utility model provides an aluminum bronze porcelain bushing flange centrifugation casting mold in order to solve the problems that rolling press fractures appear on the existing aluminum bronze porcelain bushing flange and the existing aluminum bronze porcelain bushing flange has many defects. The aluminum bronze porcelain bushing flange centrifugation casting mold is composed of an inner mold, an outer mold, a cushion plate, a gasket and a cover plate, and the inner mold is composed of a front inner mold and a rear inner mold. The aluminum bronze porcelain bushing flange centrifugation casting mold is characterized in that a multi-stage cylindrical structure is adopted on the outer mold; a pin hole is formed in an opening of the outer mold, and is used for fixing the cover plate; the front inner mold is tightly pressed by the cover plate; the rear mold is pressed by the front inner mold; the cushion plate is pressed by the rear inner mold; the gasket is pressed by the cushion plate; the gasket is clamped in the cylindrical diameter changing position of the outer mold; the shape of an aluminum bronze porcelain bushing flange is formed in the space formed by the front inner mold, the rear inner mold and the cushion plate. Due to the structure, the mold solves the problem that rolling press fractures appear on the aluminum bronze porcelain bushing flange, is flexibly produced because the height of the gasket is adjustable and has a guiding significance for actual production.
Description
Technical field
The utility model relates to the machine casting field, especially a kind of aluminium bronze insulator flange centrifugal casting mould.
Background technology
Aluminium bronze is the alloy that 20 beginnings of the century just began one's study, grows up, still, because intensity and toughness that it has high corrosion resisting property and can compare favourably with steel, thereby obtained rapidly development, become now and used widely copper alloy of the utmost point.The insulator flange is 300 and the critical component of 600MW steam turbine generator.The cylindrical portions may wall thickness is 3mm after the part processing, then with the porcelain vase roll extrusion together.And occur the situation of roll extrusion fracture when the present condition of production and processing, assembling, and more, the product quality of the product defects of aluminium bronze class material foundry goods was difficult to guarantee in the past.
Summary of the invention
Roll extrusion fracture and the many problems of defective appear in order to solve present aluminium bronze insulator flange, the utility model provides a kind of aluminium bronze insulator flange centrifugal casting mould, not only can solve the situation that the roll extrusion fracture appears in aluminium bronze insulator flange, and make simply, have actual directive significance.
Described a kind of aluminium bronze insulator flange centrifugal casting mould, formed by internal mold, external mold, backing plate, packing ring and cover plate, and internal mold is comprised of front internal mold and rear internal mold, it is characterized in that: external mold adopts multistage cylinder type, and be provided with pin hole at the external mold aperture position, be used for fixing cover plate with pin; Cover plate connects the front internal mold of tight crimping, internal mold after the front internal mold crimping, rear internal mold crimping backing plate, backing plate crimping packing ring; Packing ring is stuck in the reducing place of external mold column type; In the space of front internal mold, rear internal mold and backing plate, form the shape of aluminium bronze insulator flange.
The beneficial effects of the utility model are: not only solved the situation of roll extrusion fracture, and washer height is adjustable, so that produce flexibly, actual production is had directive significance.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further detailed.
Fig. 1 is the structure chart of aluminium bronze insulator flange centrifugal casting mould.
Wherein, 1. external mold; 2. pin; 3. front internal mold; 4. rear internal mold; 5. backing plate; 6. packing ring; 7. foundry goods; 8. cover plate.
The specific embodiment
Described a kind of aluminium bronze insulator flange centrifugal casting mould, its structure is: be comprised of internal mold, external mold 1, backing plate 5, packing ring 6 and cover plate 8, and internal mold is comprised of front internal mold 3 and rear internal mold 4, external mold 1 adopts multistage cylinder type, and be provided with pin hole at the external mold aperture position, be used for fixing cover plate 8 with pin 2; Cover plate 8 connects the front internal mold 3 of tight crimping, internal mold 4 after front internal mold 3 crimping, rear interior 4 mold pressing connection pad plates 5, backing plate 5 crimping packing rings 6; Packing ring 6 is stuck in the reducing place of external mold 1 column type; In the space of front internal mold 3, rear internal mold 4 and backing plate 5, form the shape of aluminium bronze insulator flange.
Aluminium bronze insulator flange centrifugal casting mould casting technique is: the roughing technique → Technology for Heating Processing of cleaning procedure → casting process → foundry goods.Wherein, for the cooling velocity that improves foundry goods and the utilization rate of metal, adopt the spun casting explained hereafter.Strengthening aluminium alloy refining degasification, improving in the situation of aluminium alloy degree of purity, centrifugal casting can be strengthened the cooling of aluminium alloy, simultaneously under the effect of centrifugal force field, makes oxide slag inclusion in the aluminium alloy float on the inner surface of foundry goods, realizes the foundry goods directional solidification.
