Castings are obtained, casting quality and productive temp have been seriously affected.
Fig. 1 a and Fig. 1 b is please referred to, robot arm casting is the critical component of robot, the shell of robot arm casting
1 ' of core sand core is 50~100 mesh using precoated sand, having a size of 1083.04 × 357.6 × 220.2mm.1 ' of shell core sand core includes circle
11 ' of shaped housing section and 12 ' of shallow shell portion being square being connected with its right end, one is previous on the right side wall of 12 ' of shallow shell portion
13 ' of rotary table portion there are two being arranged afterwards, from size, the 1 ' volume of shell core sand core is larger, and 1 ' length of shell core sand core is more than
1000mm, shell core sand core are easily deformed, it is difficult to be obtained qualified shell core sand core, be caused manufacturing scrap rate higher, labor intensity
Greatly, at high cost using precoated sand.It therefore, how to be to endeavour to solve in person by large-scale shell core sand core anti-deformation tool design method
The problem of
Utility model content
The purpose of the utility model is to overcome the defects of the prior art, provide a kind of shell core sand core anti-deformation tool, structure
Simply, easy to make, cost is relatively low, reduces shell core sand core deformation scrappage, improves shell core sand core and produce qualification rate.
Realize above-mentioned purpose technical solution be: a kind of shell core sand core anti-deformation tool, including bottom plate, left riser, in erect
Plate, right riser and four support columns, in which:
The left riser and right riser are oppositely arranged, and the bottom plate blocks the lower end between the left riser and right riser
Opening, the bottom of the middle riser is fixed on the bottom plate, and the middle riser is between the left riser and right riser；
The top of the left riser offers the first support slot；

The top of the right riser is opened up there are two third support slot, and described two third support slots are set in tandem
It sets；
Four support columns in square matrix be arranged on the bottom plate, and four support columns be located at the middle riser with
Between right riser.
A kind of above-mentioned shell core sand core anti-deformation tool, wherein the shell core sand core include cylindrical casing portion and and its
The connected shallow shell portion being square of right end, there are two rotary table portions for setting in tandem on the right side wall in the shallow shell portion；
The cylindrical casing portion is connected in the first support slot of the left riser；
The junction in the cylindrical casing portion and shallow shell portion is connected in the second support slot of the middle riser；
Described two rotary table portions are connected to correspondingly in described two third support slots；
The tip contact of the lower end in the shallow shell portion and four support columns is arranged.
The shell core sand core anti-deformation tool of the utility model, structure is simple, and easy to make, cost is relatively low, reduces shell core
Sand core deforms scrappage, improves shell core sand core and produces qualification rate.

Specific embodiment
In order to make those skilled in the art be better understood when the technical solution of the utility model, below with reference to attached
Its specific embodiment is described in detail in figure:
Please refer to Fig. 2 and Fig. 3, the most preferred embodiment of the utility model, a kind of shell core sand core anti-deformation tool, including bottom plate
1, left riser 2, middle riser 3, right riser 4 and four support columns 5.
Left riser 2 and right riser 4 are oppositely arranged, and bottom plate 1 blocks the lower ending opening between left riser 2 and right riser 4, in
The bottom of riser 3 is fixed on bottom plate 1, and middle riser 3 is between left riser 2 and right riser 4；The top of left riser 2 opens up
There is the first support slot 21；The top of middle riser 3 offers the second support slot 31；The top of right riser 4 is opened up there are two third branch
