Embodiment Construction

[0007] As shown in the figure, the mold frame 1 is a sand mold frame, and a seamless steel pipe 2 is arranged in the sand mold frame 1 according to the position of the oil passage of the casting.

[0008] When in use, the seamless steel pipe 2 is pretreated and then cast, so that the seamless steel pipe 2 remains intact in the casting to form an oil passage of the casting, which solves the problem of oil leakage from the oil passage.

Abstract

The invention discloses a seamless pipe casting model frame which is composed of a sand mold of the casting model frame. The seamless pipe casting model is characterized in that a pipe is buried in the sand mold of the casting model frame. The seamless pipe casting model has the advantages that the pipe is buried in the sand mold of the casing model frame; the sand mold goes to pieces when a cast is cast, the pipe is kept in the cast, a cast oil path is formed, and the original oil leakage phenomenon is overcome.

Description

technical field [0001] The invention relates to a seamless steel pipe casting mold frame, in particular to a seamless steel pipe casting mold frame capable of seamlessly connecting products to steel pipes. Background technique [0002] At present, the casting mold frame on the market is processed with deep holes on the mold frame as the heating oil circuit of the casting. Due to the large volume and thickness of the mold frame, there are different degrees of loose defects, resulting in oil leakage and low pass rate of castings. Contents of the invention [0003] The main task of the present invention is to provide a seamless steel pipe casting mold frame, in particular to a seamless steel pipe casting mold frame capable of seamlessly connecting products to steel pipes. [0004] In order to solve the above technical problems, a seamless steel pipe casting mold frame of the present invention is composed of a sand mold of the casting mold frame, and is characterized in that s...
