Abstract
The present invention relates to a sand core box, particularly to a sand core box for casting an aluminum alloy gas inlet pipe. The sand core box comprises a first sand core and a second sand core, wherein the second sand core is provided with a concave groove, and the concave groove is provided with an insert block. According to the sand core box, the insert block is arranged on a position corresponding to the sand core box to achieve second sand core change, such that a blind riser can be arranged on a thick and large position on the local during aluminum alloy gas inlet pipe casting; and a size of the insert block is corresponding to a size of the blind riser, and a material of the insert block and a material of a core box cavity main body are the same so as to compensate hot state metals, solve a shrinkage porosity problem on the position, improve cast blank quality, reduce gas inlet pipe waste products caused by cast shrinkage porosity defects, reduce a cast waste product rate to about 3% from the original 9.0%, reduce sand cost, improve cast quality, and reduce mass loss.
Description
Technical field
The present invention relates to core box, especially a kind of core box that is used for the Birmasil air inlet pipe.
Background technology
What the air inlet pipe of engine adopted mostly is the permanent mold casting of 90 ° of quiescent pouring machines, what adopt is aluminum alloy material, the air inlet pipe internal structure is by the core moulding, and core is a cold core process, and this air inlet pipe integral wall is thin, complex structure, the aluminum liquid filling type condition is poor during cast, there is thermal center in the thick general goal of foundry goods partial structurtes, do not form the feeding passage, cause shrinkage porosite, statistics is produced 15000 in batches, shrinkage porosite percent defective 9.0%.
Summary of the invention
The objective of the invention is to solve the weak point that above-mentioned prior art exists, provide a kind of reasonable in design, the rate of reducing the number of rejects and seconds, the core box that is used for the Birmasil air inlet pipe that improves the quality of products.
The present invention is achieved by the following technical solutions:
A kind of core box that is used for the Birmasil air inlet pipe, its special character are to comprise on first core 1 and second core, 2, the second cores 2 and have groove 3, be equipped with on the groove 3 and insert 4.
The present invention is used for the core box of Birmasil air inlet pipe, by install the change of realization of inserting additional at the core box opposite position to second core, when the Birmasil air inlet pipe, will thick general goal increase a blind riser like this in the part, the size of inserting is corresponding with the blind riser size, the material of inserting is consistent with core box die cavity body material, so just can compensate hot metal, solve shrinkage porosite problem herein, improved the quality of cast blank, reduced the waste product of the air inlet pipe finished product that causes because of the foundry goods shrinkage defect, the casting wasted product rate is reduced to about 3% by original about 9.0%, and has reduced the cost of sand, improve the quality of foundry goods, reduced mass loss.
Description of drawings
Fig. 1: the present invention is used for the core box structural representation of Birmasil air inlet pipe;
Fig. 2: the second sand core structure schematic diagram of the present invention;
Fig. 3: insert structure schematic diagram of the present invention;
Among the figure: 1, first core, 2, second core, 3, groove, 4, insert.
The specific embodiment
Below provide the specific embodiment of the present invention with reference to the accompanying drawings, be used for formation of the present invention is described in further detail.
Present embodiment is used for the core box of Birmasil air inlet pipe, comprises on first core 1 and second core, 2, the second cores 2 having groove 3, is equipped with on the groove 3 and inserts 4.
The blind riser of aluminium alloy air inlet pipe is by first core and the second core combination forming, and first core and second core adopt silica sand or regeneration silica sand cold core process to make, and the silica sand order is counted 50-100; Realize change to second core by installing additional at the core box opposite position to insert, the size of inserting is corresponding with the blind riser size, and the material of inserting is consistent with core box die cavity body material.
Present embodiment is used for the core box of Birmasil air inlet pipe, by install the change of realization of inserting additional at the core box opposite position to second core, when the Birmasil air inlet pipe, will thick general goal increase a blind riser like this in the part, the size of inserting is corresponding with the blind riser size, the material of inserting is consistent with core box die cavity body material, so just can compensate hot metal, solve shrinkage porosite problem herein, improved the quality of cast blank, reduced the waste product of the air inlet pipe finished product that causes because of the foundry goods shrinkage defect, the casting wasted product rate is reduced to about 3% by original about 9.0%, and has reduced the cost of sand, improve the quality of foundry goods, reduced mass loss.
The unspecified content of the present invention is prior art, and those skilled in the art can obtain to inspire from present embodiment and prior art, is out of shape to obtain other embodiment.Therefore, protection scope of the present invention should be determined according to the protection domain of claim.
Claims (1)
1. a core box that is used for the Birmasil air inlet pipe is characterized in that comprising first core (1) and second core (2), has groove (3) on second core (2), and groove is equipped with insert (4) on (3).
