Embodiment 1

[0016] The present invention comprises the following steps:

[0017] a. Put the inner hole of the Φ40mm steel pipe 5 into the dry sand 6;

[0018] b. Put the steel pipe 5 filled with dry sand into the mold cavity 4, and fix it in the surrounding sand mold 3 and sand core 1;

[0019] C. After completing the process, combine the boxes, and combine the upper and lower sand boxes of the casting sand mold 3, so that the upper sand box and the lower sand box are firmly combined;

[0020] d. Pouring the molten iron into the sand mold cavity 4 of the upper and lower sand boxes, and when the molten iron is injected into the cavity 4 and cooled, a casting is formed;

[0021] e. Clean out the dry sand 6 in the steel pipe 5, because at this time the steel pipe 5 is fused with the casting to form the inner wall of the casting hole, thereby casting a curved casting hole.

Embodiment 2

[0023] The steps of this embodiment are the same as those of Embodiment 1, except that the diameter of the steel pipe 5 is Φ25mm.

Embodiment 3

[0025] The steps of this embodiment are the same as those of Embodiment 1, except that the diameter of the steel pipe 5 is Φ10mm.

Abstract

The present invention relates to casting method, and is especially tube imbedding casting process to form bent cast hole. The process includes the following steps: setting steel tube filled with dry sand inside mold cavity and fixing in sand core; closing the mold and pouring molten iron into the mold cavity to form the casting; and eliminating dry sand from the steel tube. The process is simple and effective.

Description

technical field [0001] The present invention relates to a kind of traditional casting method, more specifically relates to a kind of buried pipe casting curved casting hole method. Background technique [0002] At present, in the field of casting, the diameter of the sand casting hole is still controlled above Φ40mm due to the influence of various factors such as the strength of the sand core. Due to the traditional sand casting method, it is difficult to cast holes with a diameter smaller than Φ40mm, especially some It is even more impossible to have a curved casting hole smaller than Φ40mm, and it cannot be realized by cold working, so it cannot meet the design requirements and affect the overall performance of the part. Contents of the invention [0003] The technical problem to be solved by the present invention is: to overcome the defects of traditional sand molds such as small diameter, insufficient strength, easy sand sticking, etc., to provide a buried pipe casting...
