Description
Technical field
The utility model relates to casting field more particularly to a kind of split type sand cores of engineering machinery rear cover casting.
Background technique
Common engineering machinery rear cover is formed using the mode of casting, and casting its inner cavity of sand core is complex, wherein wrapping
A large amount of raised block is contained, multiple macropores communicated with the outside world, general between sandbox shell there are also multiple locating pieces by sandbox
The cavity of formation is divided into two, and in addition to this there are also sand cores, these all increase difficulty to the design of sand core.Work traditional at present
The assembly of sand core process of journey machinery rear cover is more, needs to use many loose piece and sand core, and this traditional sand core structure lacks
Point is: need to open core box and more loose pieces more, production process is complicated, and it is time-consuming and laborious, increase cost；In addition, general
Engineering machinery rear cover uses monolithic construction, causes to there are a large amount of burrs and is difficult to subsequent processing.Therefore it needs
Want that one kind can be positioned quickly and sand using amount is few, high-efficient sand core realizes the production of engineering machinery rear cover.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of split type sand cores of engineering machinery rear cover casting, can
Solve to pour in mold that sand using amount is big, sand core is more in general engineering machinery rear cover, loose piece mostly with it is at high cost, and use monoblock type
The problem of structure causes burr to be excessively difficult to.
In order to solve the above technical problems, the technical solution of the utility model are as follows: a kind of engineering machinery rear cover casting fission
Formula sand core, innovative point are: including sand core seat, sand mold, sand core group and sand core group link block；The sand mold is arranged in sand core seat
On, one end of sand core group is connected with sand core group link block, and the other end of sand core group is connected with sand core seat, the side of the sand core group
It is connected with sand mold；
The sand core seat L-shaped plate structure is provided with the sand core for accommodating sand core group end on the bottom edge of the sand core seat
Locating slot is organized, the sand mold locating slot for accommodating sand mold end is provided on the side of the sand core seat；
The sand core group includes that a pair is symmetrically arranged with sand core block, and the sand core block includes half arc lower section sand core block, flat
Flat-shaped interlude sand core block and cylindric upper section sand core block；One end of the half arc lower section sand core block is connected to sand core seat
On sand core group locating slot, the both ends of the flat interlude sand core block are connected to the another of half arc lower section sand core block
The one end at end and cylindric upper section sand core block, the other end of the cylindric upper section sand core block are connected on sand core group link block；
The sand core group link block is provided with the holding tank with cylindric upper section sand core block one end fits；The flat interlude sand
Pellet is extended outward sand core item, and the sand core end is connected with sand mold.
Further, the angle that the sand core item extends from the flat interlude sand core block of sand core group is 90 degree.
Utility model has the advantages that
1) by casting of the combination as engineering machinery rear cover between sand core group and sand mold in the utility model, in
The sand core structure of empty formula, so that sand core is more light, and reduces sand using amount, cost waits until to reduce, and selects reasonable parting position
It sets, the minimum number of assembly of sand core is made in the case where reducing and using loose piece, simplifies the production of engineering machinery rear cover
Journey；The burr of the split type structure of use, the engineering machinery rear cover for casting out is few, is convenient for subsequent processing.
Detailed description of the invention
Utility model will be further described in detail below with reference to the attached drawings and specific embodiments.
Fig. 1 is a kind of structural front view of the split type sand core of engineering machinery rear cover casting of the utility model.
