Abstract

The utility model relates to a core assembly which comprises at least two core groups mutually pieced together, wherein, each core group comprises a plurality of sand cores, the sand cores are mutually pieced together to form a shape of a casting part, a running channel is arranged in at least one sand core in the sand cores of each core group, the sand cores with running channels of the two core groups are arranged in an adjacent manner, and the running channels of the two sand cores are combined to form a gating system of the core group. The core assembly has the advantages of saving the investment of the external mold (metal mold and sand mold) and simple and convenient operation; the gating system is formed by piecing the single cores together without an extra sheath gating system; moreover, the production efficiency can be improved so that a plurality of casing parts can be product in one-time pouring; and the process for pouring the casting parts by using the core assembly is suitable for the demands of development of the modernized manufacturing industry.

Description

Core assembly

Technical field

The utility model relates to the core assembly in the castings production field.

Background technology

In the castings production process, casting process is the emphasis that everybody studied always.Core assembly pouring technology is used for a long time in castings production, and currently used technology has following two kinds:

One, at first a plurality of cores are formed a core group, and be placed in the external mold (metal pattern or sand mold mould), carry out moulding by casting by the running gate system on the external mold, obtain foundry goods, employed core core group is just in order to form the inner cavity segment of foundry goods;

Two, with after core group of a plurality of cores compositions, directly add running gate system, water and outpour single foundry goods.

More than two kinds of technologies, the once-cast process can only form single foundry goods, production efficiency is lower, and production cost is higher.

Along with the continuous development of modern manufacturing industry, the height of product price needs technology content wherein to decide, and under the basis of equivalent technology content, how constantly to reduce production costs becomes the emphasis that people pay close attention to.

The utility model content

The core assembly that provides a kind of production cost lower is provided the purpose of this utility model, uses a plurality of foundry goods of this core assembly pouring, and production efficiency is higher, production cost is lower, and cast is plastic a plurality of foundry goods through single.

For achieving the above object, the technical scheme that the utility model adopted is:

A kind of core assembly, it comprises the core group of at least two mutual amalgamations, each core group comprises a plurality of cores, the mutual amalgamation of a plurality of cores forms the shape of foundry goods, offer running channel in a plurality of cores of each core group at least one, belong to the adjacent setting of core that has running channel on its of two core groups respectively, and the running channel of two cores is combined to form a running gate system of core assembly.

Because the employing of technique scheme, the utility model compared with prior art has the following advantages:

Whole shapes of foundry goods all are assembled into a core group by a plurality of cores and form, need not install the shape that an external mold (metal outer mold, sand mold external mold) with potting syrup drainage forms foundry goods in core group outside again additional, subsequently that these are independent core amalgamation and forms running gate system together in the mosaic.The a plurality of casting process of this core assembly pouring can be saved the investment of external mold (metal pattern, sand mold mould) mould, and it is easy and simple to handle, do not need to add other crust running gate system, only these single core spellings need be lumped together and just form running gate system, can also enhance productivity, once-cast can a plurality of foundry goods of output.The technology of a plurality of foundry goods of this core assembly pouring is applicable to the demand of modernized development of manufacturing.

Fig. 2 is combined into the schematic diagram of running gate system for a plurality of core groups;

Wherein: 1, core group; 2, core; 3, running gate system; 31, running channel; 4, foundry goods; 5, core assembly.

The specific embodiment

Core assembly 5 as shown in Figure 2 comprises the core group 1 of at least two mutual amalgamations.

As shown in Figure 1, each core group 1 comprises a plurality of cores 2, the shape of a plurality of core 2 mutual amalgamations formation foundry goods 4, offer running channel 31 in a plurality of cores 2 of each core group 1 at least one, running channel 31 is positioned at the position, edge of core group 1, belong to the core 2 adjacent settings that have running channel 31 on its of two core groups 1 respectively, and the running channel 31 of two cores 2 is combined to form a running gate system 3 of core assembly 5.Each core group 1 forms a foundry goods 4 through the cast back.

Use the single of above-mentioned core assembly 5 to pour into a mould a plurality of casting process, comprise the steps:

At first, a plurality of cores 2 are formed a core group 1, the shape of a plurality of core 2 mutual amalgamations formation foundry goods 4; Then, a plurality of core groups 1 of amalgamation make the running channel 31 on two adjacent cores 2 be combined to form running gate system 3; At last, by the running gate system 3 that is arranged between the adjacent core group 1 potting syrup is injected each core group 1.

Whole shapes of foundry goods 4 all are assembled into a core group 1 by a plurality of cores 2 and form, need not install an external mold (metal outer mold again additional in core group 1 outside with potting syrup drainage, the sand mold external mold) forms the shape of foundry goods 4, subsequently together with 1 amalgamation of a plurality of independently core group, and form running gate system 3 in the mosaic, running channel 31 is that band is on certain core 2 of core group 1, after single core group 1 assembling is finished, form a running gate system 3 by these two adjacent core 2 amalgamations, running gate system 3 can be communicated with two core groups, three or more core group 1, so just, can once-cast two, three or a plurality of foundry goods 4.。The a plurality of casting process of this core assembly pouring can be saved the investment of external mold (metal pattern, sand mold mould) mould, and it is easy and simple to handle, do not need to add other crust running gate system, only these single core spellings need be lumped together and just form running gate system, can also enhance productivity, once-cast can a plurality of foundry goods of output.The a plurality of casting process of this core assembly pouring are applicable to the demand of modernized development of manufacturing.
