The following core mode that comprehensive each factory at present adopts compares:

1, core scheme under the manipulator: the precision height of following core, sandbox and integral core coremaking need not the location, but need the frock of a large amount of stoolings and bigger equipment investment.

2, mechanical automation lower core device: the efficient height, can realize the integrated production of on line of molding and core making, but the mutually accurate detent mechanism of modeling process and coremaking is required sternly to need bigger investment and stooling device.

3, manual core down: need easy suspender to realize core process down, but precision is low, needs manual assist location, benefit is low.Fuse and sand mold are fragile.

Summary of the invention

The utility model provides a kind of integral core lower core device in order to solve the problems referred to above that the following core mode of integral core bolster, bogie side frame exists in the prior art.

The utility model adopts following technical scheme to realize:

The integral core lower core device, it is characterized in that it comprises that two ends are fixed on the Heng Liang on the sandbox, Heng Liang top is provided with suspension ring, the Heng Liang bottom is symmetrical arranged four upper sliding sleeves with its center, the interior setting of upper sliding sleeve is its bearing pin that moves up and down relatively, two bearing pins of weighing apparatus beam symmetry connect by connecting rod relatively, and clamping device is installed at the connecting rod middle part.Connect by lower supporting plate between the connecting rod.The Heng Liang two ends connect perpendicular bracing frame, and perpendicular base plate is established in the bracing frame lower end, and the base plate inboard is provided with supporting rod seat, and the plate outer side setting can insert in the alignment pin of sandbox.

Described clamping device comprises outer claw and the interior claw that is hinged on the lower supporting plate, and inside and outside claw upper end connects by hinged switch.Can be used for bolster.

Described clamping device comprises the positioning body that can insert in the core body hole, and the positioning body bottom is provided with movable bayonet lock switch.Can be used for bogie side frame.

The utlity model has following beneficial effect:

1, improve the production operation efficiency of core down, following core operation was less than 10 minutes 1 casees;

2, reduce handwork improves product to damaging of core interior presentation quality;

3, the frock of a large amount of minimizing stoolings and transhipment time, simplify core process down;

4, realize the on line production operation that moulding and system integral core are produced, save the operation place;

5, reach the machinery purpose of core down.

The utility model can use in the following core process of at present production integral core bolster, bogie side frame, has the characteristics of simple in structure, easy to operate, small investment, instant effect, has tangible economic benefit.The moulding production process is adopted in location of the present utility model, the unification of cabinet production process is decided to be benchmark, guaranteed the following core precision of integral core, satisfied drawing and relevant integral core manufacturing requirements, can generally promote the use of in the following core process of the integral core bolster of producing other model, bogie side frame and use.
