Abstract
The invention belongs to the field of casting, and in particular, relates to a casting process for positioning by peripheral sand core positioning reference pieces. The casting process comprises the steps of mold manufacturing, modeling, core manufacturing, mold closing, casting, shakeout, cleaning, shot blasting and rust prevention; and in the mold manufacturing process, a model is connected with a baseplate, and multiple peripheral sand core positioning reference pieces are arranged in the edge position, contacted with the baseplate, of the model. The casting process forms the periphery of a casting mold by cores, wherein the cores at the periphery of the casting mold are peripheral sand cores; and the method guarantees the position accuracy of the peripheral cores so as to guarantee the machining precision.
Description
Technical field
The invention belongs to casting field, be specifically related to a kind of casting technique using peripheral core positioning datum sheet location.
Background technology
Cast more complicated, during the foundry goods of very irregular, can face and produce bigger cavity with model, put into the fuse (peripheral core) made afterwards near cavity wall, form the scheme of final die cavity afterwards.And fuse lower end, periphery easily positions, and fuse particular location cannot determine, and it is all the face of strike-ofing outside peripheral fuse, size is forbidden, processing is based on digital control processing now, profile takes three direction black skins as machining benchmark, often due to peripheral core assembly is forbidden to cause machining benchmark to offset, thus affects Mechanical processing of casting size offset.
Summary of the invention
Defect in view of above-mentioned prior art, the concrete scheme that the present invention uses is a kind of casting technique using peripheral core positioning datum sheet location, including molding, moulding, make core, mould assembly, cast, knockout, cleaning, ball blast and antirust, in its patternmaking process, being connected with base plate by model, model and the marginal position of contacts baseplate arrange some peripheral core positioning datum sheets.
The model with some peripheral core positioning datum sheets is extracted during described moulding, put into peripheral core afterwards, the groove stayed on molding sand according to peripheral core positioning datum sheets some in patternmaking process, the peripheral core position dimension of inspection is stretched the most accurate with cotton rope, if peripheral core will definitely not adjusted by line, then peripheral core back side back-up sand is fixed.
Periphery core positioning datum sheet is preferably perpendicular to base plate arrange, and is perpendicular to the side of model.
The described position by peripheral core positioning datum sheet setting determines according to the size of peripheral core to be produced.
Using the casting technique model of peripheral core positioning datum sheet location, its model is connected with base plate, and model and the marginal position of contacts baseplate arrange some peripheral core positioning datum sheets.The position of the most described peripheral core positioning datum sheet determines according to the size of peripheral core to be produced.
Preferably peripheral core positioning datum sheet is vertical with the side of model, the most vertical with described base plate.
Beneficial effects of the present invention: the present invention is by the molecular casting technique of core for casting mold surrounding, wherein the fuse of casting mold surrounding is referred to as peripheral core, and the method ensure that the positional accuracy of peripheral core, thus ensure that machining accuracy.

Detailed description of the invention
The present invention is by the molecular casting technique of core for casting mold surrounding, wherein the fuse of casting mold surrounding is referred to as peripheral core, this casting as shown in Figure 6 is more complicated, during the foundry goods of very irregular, typically first produce bigger cavity with model, put into the fuse (peripheral core) made afterwards near cavity wall, form final die cavity afterwards.
Use the casting technique of peripheral core positioning datum sheet location, including molding, moulding, make core, mould assembly, cast, knockout, cleaning, ball blast and antirust, in its patternmaking process, being connected with base plate 4 by model 5, the marginal position that model 5 contacts with base plate 4 inserts some peripheral core positioning datum sheets 6.
The model 5 with some peripheral core positioning datum sheets 6 is extracted during described moulding, put into peripheral core 1 afterwards, the groove stayed on molding sand according to peripheral core positioning datum sheets 6 some in patternmaking process, the peripheral core position dimension of inspection is stretched the most accurate with cotton rope, if peripheral core will definitely not adjusted by line, then peripheral core back side back-up sand is fixed.
Preferably peripheral core positioning datum sheet 6 is inserted perpendicularly into the side of model 4.
Described the position that peripheral core positioning datum sheet 6 inserts is determined according to the size of peripheral core 1 to be produced.
Using the casting technique model of peripheral core positioning datum sheet location, its model 5 is connected with base plate 4, and the marginal position that model 5 contacts with base plate 4 arranges some peripheral core positioning datum sheets 6.The position of the most described peripheral core positioning datum sheet 6 determines according to the size of peripheral core 1 to be produced.
Preferably peripheral core positioning datum sheet 6 is vertical with the side of model 5, the most vertical with described base plate 4.
Feature of the present invention is to make outline spacer the most peripheral core positioning datum sheet 6 in peripheral core 1 top box face on the base plate 4 of model 5, positioning datum sheet 6 is directly extracted during moulding, peripheral core 1 position dimension of inspection is stretched with cotton rope the most accurate after lower core, if core will definitely not adjusted by line, then the back-up sand of the core back side is fixed, the method ensure that the positional accuracy of peripheral core, thus ensure that machining accuracy.It addition, base plate 4 is connected with model 5 so that model is more easy to take out.The present invention also can process the die cavity that moulding as shown in Figures 2 and 3 is complicated.
