Cast imbedding lifting lug casting pipe

Abstract

The invention provides a cast imbedding lifting lug casting pipe, wherein a lifting lug casting pipe is cast in a casting body. The cast imbedding lifting lug casting pipe is characterized in that the lifting lug casting pipe is provided with a groove at the outer wall of the casting body, the depth of the groove is 0.5-5mm, and the included angle is 0-60 degrees; and the inside surface of the included angle of the groove and the contact surface of the casting body are two parallel surfaces. When the cast imbedding lifting lug casting pipe is used, since the lifting lug casting pipe is provided with a groove at the outer wall of the casting body, the lifting lug casting pipe can be cleared by slightly knocking without damaging the body of the casting, the depth of the groove is 0.5-5mm and the included angle is 0-60 degrees, thus facilitating knocking; and since the inside surface of the included angle of the groove and the contact surface of the casting body are two parallel surfaces, namely the lifting lug casting pipe after knocking forms a plane on the surface of the casting body, no mark is left after knocking. The cast imbedding lifting lug casting pipe is easy to clean, so that the working efficiency for cleaning casting is improved, and the quality of the casting is ensured. The cast imbedding lifting lug casting pipe has the characteristics of being low in production cost, simple in structure, convenient to install, firm, safe and reliable.

Description

technical field [0001] The invention relates to an easy-to-clean cast-in standard part for full-form casting, in particular to a cast-in tube for full-form casting and lost-foam casting inlaid casting lugs. Background technique [0002] Inlay casting (casting) of standard parts has been widely used in full mold casting production. However, when casting standard castings, due to the consideration of the support and stability of the molding sand, there are always redundant parts in the length or width direction of the castings that need to be cast out at the same time. There are often cutting and cleaning interferences in the structure of the castings, and oxygen-acetylene is used for cleaning. Fire burning, cutting, removal and grinding will result in increased cleaning workload, uneven end faces of standard parts, time-consuming and laborious, and even damage to the casting body, and poor appearance quality of the castings. Contents of the invention [0003] In order to s...

However, when casting standard castings, due to the consideration of the support and stability of the molding sand, there are always redundant parts in the length or width direction of the castings that need to be cast out at the same time. There are often cutting and cleaning interferences in the structure of the castings, and oxygen-acetylene is used for cleaning. Hot burning, cutting, removal and grinding will lead to increased cleaning workload, uneven end faces of standard parts, time-consuming and laborious, and even damage to the casting body, and the problem of poor appearance quality of the castings
