Abstract
A kind of large aluminum alloy casts nacelle metalloid shell combination core mold, it is characterized in that：Upper core core mould positions including mould under mould locating groove, fixed crust, upper core under mould, upper core under upper core with mould under upper core and the concavo-convex positioning of crust, crust bumps, eight pieces of moulds, upper core box mold, upper core box mold and upper core mold and the concavo-convex positioning of crust, fixed crust uses concavo-convex location fit, inner mould is divided into eight pieces of moulds according to loose piece withdrawing pattern direction, and is positioned by mould locating groove under upper core and fixed crust.The advantages of this is practical new is that combined core box is reduced due to operation difficulty caused by core height, strengthen the intensity and die life of core, reduce mold design difficulty, when easy to operation to loose piece and core corner part moulding control, using irony alignment pin strictly control core both horizontally and vertically on cooperation.
Description
Technical field
Casting technology field is the utility model is related to, particularly a kind of large aluminum alloy casting nacelle metalloid shell combination
Core mold.
Background technology
Nacelle metalloid housing is cast as a kind of novel large aluminium alloy, its inner-cavity structure is complicated, loose piece is more, internal
Size requirement is strict, difficult using one-piece core box mold design, the operation difficulty increase of loose piece and corner part, easily causes chi
The problems such as very little deviation.And integral sand core easily causes core deformation and damage because centre has a big chunk hollow part.
The content of the invention
The purpose of this utility model is to provide one kind and can guarantee that sand core strength, improves the dimensional accuracy of internal labyrinth,
It is easy to mold design and the large aluminum alloy of production operation to cast nacelle metalloid shell combination core mold.
The utility model is achieved in that it includes upper core core mould and lower core core mould, under upper core
Mould and the concavo-convex positioning of crust, the concavo-convex positioning of crust under mould locating groove, fixed crust, upper core under mould, upper core, eight
Block mould, upper core mold, upper core mold and crust are concavo-convex to be positioned, triangular structure alignment pin, lower core mold,
Mould, internal loose piece, cutting loose piece, core and sand mold positioning, lower core mold position with mould under lower core under lower core,
Core and sand mold positioning position with lower core mold, jack positioning 17 and alignment pin, it is characterized in that：Upper core core mould bag
Include mould and mould and crust under upper core under mould under core, mould locating groove under upper core, fixed crust, upper core
Bumps positioning, the concavo-convex positioning of crust, eight pieces of moulds, upper core box mold, upper core box mold and upper core mold and crust
Bumps positioning, fixed crust use concavo-convex location fit, and inner mould is divided into eight pieces of moulds according to loose piece withdrawing pattern direction, and by upper
Mould locating groove and fixed crust position under core.
The advantages of this is practical new is that combined core box is reduced due to operation difficulty caused by core height, strengthens core
Intensity and die life, mold design difficulty is reduced, moulding control when easy to operation to loose piece and core corner part,
Using irony alignment pin strictly control core both horizontally and vertically on cooperation.
Brief description of the drawings：
Accompanying drawing is integrated below to be further described the utility model：
Fig. 1 is the upper core mold structural representation of large aluminum alloy casting nacelle metalloid shell combination core mold；
