Abstract
A plaster model seal outer cover for low-pressure casting of an impeller comprises an upper-layer supporting cover and a lower-layer supporting cover. The upper-layer supporting cover is in the shape of a funnel, a plaster model is arranged in the upper-layer supporting cover, the lower-layer supporting cover is in the shape of a cylinder, an annular groove is formed in the bottom surface of the upper-layer supporting cover, the upper end of the lower-layer supporting cover is provided with an annular boss, the annular boss at the upper end of the lower-layer supporting cover can be imbedded into the annular groove in the upper-layer supporting cover, the lower-layer supporting cover and the upper-layer supporting cover are fixed through a plurality of bolts, a cushioning chamber is formed between the lower-layer supporting cover and the upper-layer supporting cover, and a cushioning spring is arranged in the cushioning chamber. The plaster model seal outer cover has the advantages of being simple in structure, convenient to operate, good in cushioning effect and the like and can effectively avoid mutual movement of the plaster model and the upper-layer supporting cover during compression die assembly, and therefore plaster model cracking tendency is reduced greatly.
Description
Technical field
The utility model belongs to the aluminum alloy low-pressure casting field, particularly relates to a kind of impeller low pressure casting gypsum mould hermetically sealed case.
Background technology
Domestic in the supercharger impeller low pressure casting, for the crackle that reduces gypsum mould in pressurization destroys, the method that employing adds protective sleeve in the gypsum mould outside supports gypsum mould, in order to avoid gypsum mould is destroyed by pressure break, at present, protective sleeve commonly used is the version of integral type, clamping pressure to chill above gypsum mould does not cushion, sometimes gypsum mould is easily produced to the pressure break tendency larger, Given this, the hermetically sealed case of our design adopts double-decker, adopt spring buffer between upper and lower two-layer support, reduce the impact of mold clamping force to gypsum mould, reduce the shell ratio of splitting of gypsum mould.
The utility model content
The purpose of this utility model is exactly defect and the deficiency existed for overcoming above-mentioned prior art, and provide a kind of simple in structure, easy to operate impeller low pressure casting gypsum mould hermetically sealed case, this overcoat adopts double-decker, adopt spring buffer between upper and lower two-layer support, reduce the impact of mold clamping force to gypsum mould, reduce the shell ratio of splitting of gypsum mould, be applicable to the supercharger impeller low pressure casting, the crackle that reduces gypsum mould in pressurization destroys.
The technical scheme adopted is:
A kind of impeller low pressure casting gypsum mould hermetically sealed case, comprise upper strata support set and lower layer support cover, it is characterized in that described upper strata support set is funnel-form, be equiped with plaster cast in it, lower layer support Tao Wei garden tubular, the bottom surface of upper strata support set is provided with annular groove, the upper end of lower layer support cover has annular boss, the annular boss of lower layer support set upper side can be inserted in the annular groove of upper strata support set, the lower layer support cover is fixed by a plurality of bolts with the upper strata support set, between lower layer support cover and upper strata support set, cushion chamber is arranged, be equiped with buffer spring in cushion chamber.
The utlity model has the advantages such as simple in structure, easy to operate, good buffer effect, in the time of can effectively avoiding adding press-fitting mould, the mutual motion that gypsum mould and upper strata support set exist, split the shell tendency thereby greatly reduced gypsum mould.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Refer to Fig. 1, a kind of impeller low pressure casting gypsum mould hermetically sealed case of the present invention, comprise upper strata support set 1 and lower layer support cover 2, upper strata support set 1 is funnel-form, be equiped with plaster cast 4 in it, lower layer support cover 2 is the garden tubular, the bottom surface of upper strata support set 1 is provided with annular groove 6, the upper end of lower layer support cover has annular boss 7, the annular boss 7 of lower layer support set upper side can be inserted in the annular groove 6 of upper strata support set, lower layer support cover 2 is fixedly connected with by bolt 8 with upper strata support set 1, between lower layer support cover 2 and upper strata support set 1, cushion chamber 5 is arranged, be equiped with buffer spring 3 in cushion chamber 5.
