Utility model content
In view of the above-mentioned problems, the utility model provides a kind of type core positioning support structure of front axle housing body sand mo(u)ld, energy
Solve the bending deformation that 1.8m is easy to happen up and down direction with upper core by the casting that both ends positioning support is cast, casting product
The poor technical problem of matter.
Its technical solution be it is such, a kind of type core positioning support structure of front axle housing body sand mo(u)ld, sand mo(u)ld includes on sand mold
Mould, sand mold lower die and type core, it is characterised in that: the type core positioning support structure includes two groups of location structures and two groups of support knots
Structure, location structure described in two groups are respectively arranged at the front and rear sides of sand mold upper mold, sand mold lower die and type core centre position；Two groups of branch
Support structure is set to sand mold upper mold, sand mold lower die and type core left and right ends.
Further, the location structure includes being set to the first locating convex block in sand mold lower die along position, being set to
Second locating convex block of type core middle part bit width direction two sides, locating piece, the third positioning for being set to locating piece upper and lower ends
Convex block is set to the first locating slot under sand mold upper mold along position, is set to sand mold upper mold middle part bit width direction two sides
Second locating slot, the third locating slot for being set to the second positioning block bottom are set to sand mold lower die middle part bit width direction two
4th locating slot of side, first locating convex block, the third locating convex block vertically extend, second convex
Block extends along the longitudinal direction, first locating slot, second locating slot and the third locating slot downwardly facing opening, and described
Four locating slots are upwardly opening；
The support construction includes the support column for being set to type core left and right ends, is set to the upper of sand mold upper mold left and right ends
Support slot and the lower support slot for being set to sand mold lower die left and right ends；
After the sand mold upper mold, the sand mold lower die, type core and locating piece assembling, the first locating convex block inserting
In in the first locating slot, in the second locating slot, two thirds are positioned for second locating convex block, locating piece split from top to bottom
Convex block is plugged in third locating slot, in the 4th locating slot respectively；The support column is plugged in support slot and lower support slot split
Groove body in.
Further, the support column is cylinder, and the upper support slot, the lower support slot are semi-cylindrical.
Further, second locating slot is located at length direction two sides and is respectively equipped with the first locating convex block.
The structure that the utility model is supported by using interfix and left and right ends, can effectively reduce casting in upper and lower
The bending in direction, it is ensured that casting quality；Specifically, sand mold upper mold and sand mold lower die pass through the first locating slot, first between the two
Locating convex block cooperation positioning, it is fixed by the second locating slot, locating piece, third between sand mold upper mold, sand mold lower die and type core three
Position convex block and the cooperation positioning of third locating slot；The both ends of type core pass through upper support slot, the sand mold of support column Yu sand mold upper mold respectively
The lower support slot of lower die supports；And then realize effective support of the positioning split and type core of three.
Detailed description of the invention
Fig. 1 is the decomposition texture schematic diagram of the utility model.
