Abstract
The utility model provides a kind of heavy castings sandbox, the expansion of casting process middle case can be solved, the technical issues of leading to connection component flexural deformation, can not fix upper box and lower box, influence casting.It includes upper box, lower box and connection component, it is characterised in that：Connection component includes the top board and lower platen of screw rod, nut and strip, top board, lower platen are divided on the upside of upper box and are set on the downside of lower box and along the width/height direction of babinet, top board and lower platen both ends are respectively equipped with the slot hole extended along its length, and screw rod both ends pass through nut check after extending through top board and the corresponding slot hole of lower platen.
Description
Technical field
The utility model is related to sand casting fields, and in particular to a kind of heavy castings sandbox.
Background technology
In sand casting field, traditional casting generally comprises upper box, lower box and connection component, the company with sandbox
Connected components include being divided into upper box side, the upper connecting base of lower box side, lower connecting base and screw bolt and nut, upper company
Joint chair and lower connecting base be mutually paired after by bolt, nut check.Since during casting, casting easily occurs outside
It is the phenomenon that expansion, particularly evident in the production process of heavy castings, lead to upper connecting base, lower connecting base flexural deformation, cause
Bolt can not run through upper connecting base and lower connecting base is perforated accordingly, i.e., can not fix upper box and lower box, influence to use.
Utility model content
In view of the above-mentioned problems, the utility model provides a kind of heavy castings sandbox, can solve to cast in casting process
Part expands, the technical issues of leading to connection component flexural deformation, can not fix upper box and lower box, influence casting quality.
Its technical solution is such, including upper box, lower box and connection component, it is characterised in that：The connection
Component includes the top board and lower platen of screw rod, nut and strip, and the top board, the lower platen are divided into the top box
It is set on the upside of body and on the downside of the lower box and along the width/height direction of babinet, the top board and the lower platen two
End is respectively equipped with the slot hole extended along its length, and the screw rod both ends extend through the top board and the lower platen is corresponding
Slot hole after pass through nut check.
Further, buffer gear is further included, the buffer gear includes top plate and buffer cell, and the top plate passes through
Equally distributed buffer cell is supported on the upside of the upper box.
Further, the buffer cell includes a pair of symmetrically arranged arc shape pressing plate, the arc shape pressing plate it is upper,
Lower both ends are fixedly connected respectively with the top plate, the upper box.
Further, the connection component is equipped with two groups, and is symmetrically distributed in babinet both sides.
Further, it is provided with gasket between the nut and the top board/lower platen.
Further, the section of the top board and the lower platen is undercut shape structure, the top board both sides
The upper surface of top plate described in longitudinal bracing portion compresses, the cross-brace part of the lower platen and the lower face of the lower box
Fitting.
The utility model clamps sandbox body by top board, lower platen, can improve clamping effect, substantially reduces because of casting
Top board, lower platen flexural deformation caused by the expansion of process medium casting, meanwhile, top board and lower platen both ends are respectively equipped with along length
The slot hole of direction extension is spent, on the one hand can avoid causing hole position that can not be aligned because of top board, pushing plate benging, it is ensured that sandbox
Effective clamping of body, on the other hand, during casting expands, expansive force meeting lead-screw is moved along slot hole, reduces screw rod
Flexural deformation.
Description of the drawings
Fig. 1 is the main structure diagram of the utility model.
Fig. 2 is the overlooking the structure diagram of the utility model.
Specific embodiment
A kind of heavy castings sandbox, as shown in Figure 1 and Figure 2, including upper box 1, lower box 2 and connection component, top box
Body 1 and 2 both sides of lower box pass through upper positioning seat 7, lower positioning seat 8 and positioning pin（It is not shown）Cooperation positioning, connection group
Part is equipped with two groups, and is symmetrically distributed in sandbox body both sides, and connection component includes 3 and of top board of screw rod 5, nut 6 and strip
Lower platen 4, top board 3, lower platen 4 are divided into 1 upside of upper box and 2 downside of lower box and along the width/height sides of babinet
To setting, top board 3 and 4 both ends of lower platen are respectively equipped with the slot hole 12 extended along its length, and 5 both ends of screw rod extend through
It is locked after 4 corresponding slot hole 12 of pressing plate 3 and lower platen by nut 6, pad is provided between 3/ lower platen 4 of nut 6 and top board
Piece.
It further includes buffer gear, and buffer gear includes top plate 9 and buffer cell, and top plate 9 passes through equally distributed buffering
Unit supports are in 1 upside of upper box；Buffer cell includes a pair of symmetrically arranged arc shape pressing plate 10,11, arc shape pressing plate 10,
11 upper/lower terminal is fixedly connected respectively with top plate 9, upper box 1, the setting of buffer gear, can be passed through when babinet expands
Buffer cell deforms energy-absorbing, reduces top board, lower platen flexural deformation, while buffer cell releases energy after casting, promotes case
Body deformation recovery.
The section of top board 3 and lower platen 4 be undercut shape structure, the longitudinal bracing portion compresses top of 3 both sides of top board
The upper surface of plate, the cross-brace part of lower platen 4 are bonded with the lower face of lower box 2.
