Abstract

The utility model provides a sand core molding structure. The sand core molding structure comprises a lower sand box, a side sand core and an upper flat plate, wherein a lower sand mould is arranged in the lower sand box, and the side sand core is arranged in the lower sand mould. The upper flat plate is provided with a pouring hole, and the side sand core and the lower sand mould are integrated.

Description

The core modeling structure
Technical field:
The utility model relates to a kind of core modeling structure.
Background technology:
The modeling structure of core can directly have influence on the moulding operation, and the unreasonable meeting of structure causes final products to have various defectives, needs subsequent handling to handle, and is cumbersome.Such as; Traditional modeling structure mainly is made up of cope 8, drag box 1, during moulding, and the first sand molding that in drag box 1, descends; Accomplish the making of sand mold 3 down after the demoulding; Then drag box 1 upset is lowered to limit core 2, in cope 8, makes sand mold 9 at last, will go up sand mold 3, get final product after sand mold 9 mould assembling down.But in this structure, in following core 2, be difficult to guarantee all can have the gap usually between limit core 2 and the following sand mold 3 through cope 8, drag box 1 matched moulds; Behind casting complete, these gaps can form the defective of overlap, burr on foundry goods, influence the fineness of cast(ing) surface; But also need workman's operation of polishing; The subsequent operation of product is cumbersome, and working strength of workers is bigger, inefficiency.
The utility model content:
For solving above-mentioned technical problem, the utility model provides a kind of core modeling structure of reducing product defects, enhancing productivity of helping.
The technical scheme of the utility model is, a kind of core modeling structure with following structure is provided, and it comprises drag box, limit core; Be provided with down sand mold in the drag box, the limit core is positioned at sand mold down, and it also comprises upper flat plate; Upper flat plate is provided with plug hole, and the limit core is an one with following sand mold.
After adopting said structure, the utlity model has following advantage:
Cancel original cope, when moulding, on casting template, place drag box earlier, put into the limit core then; Add molding sand, use moulding machine to carry out vibration molding, after molding sand compresses, molding; So just can limit core and following sand mold be combined together, can avoid the appearance in gap, can effectively avoid defectives such as overlap, burr, need not follow-up operations such as polishing; Help enhancing productivity, replace original cope, can reduce the material of going up sand mold by upper flat plate; The use amount of molding sand is less, helps reducing production costs and environmental protection, and upper flat plate operation room list is reliable simultaneously.
Description of drawings:
Fig. 1 is the sketch map of prior art medium sand core sand moulding structure;
Fig. 2 is the sketch map of the utility model core modeling structure;
The specific embodiment:
Below in conjunction with accompanying drawing and specific embodiment the utility model is described further.
Comparison diagram 1, Fig. 2 can know, the utility model core modeling structure, and it comprises drag box 1, limit core 2; Be provided with down in the drag box 1 in 3 times sand molds 3 of sand mold and comprise sprue 6 and die cavity 7;, limit core 2 is positioned at sand mold 3 down, and it also comprises upper flat plate 4; Upper flat plate 4 is provided with plug hole 5, and limit core 2 is an one with following sand mold 3.Behind upper flat plate 4 and drag box 1 matched moulds, plug hole 5 docks with sprue 6.After adopting this structure, when making down sand mold 3, directly limit core 2 is put into earlier in the drag box 1, treat down that sand mold 3 compresses moulding after, limit core 2 and following sand mold 3 are combined together, just can avoid the gap occurring between limit core 2 and the following sand mold 3.
