Mould for spheroidal graphite iron casting

Abstract

The invention discloses a mould for a spheroidal graphite iron casting. The mould for the spheroidal graphite iron casting comprises a mould main body, a processing box and a support column. The top of the mould main body is fixedly connected with the processing box. The bottom of the processing box is fixedly connected with the support column. The middle portion of one side in the processing boxis connected with a feeding channel in a penetrated mode. The middle portion of the top in the processing box is fixedly connected with a graphite treatment box. The middle portion of the other side in the processing box is fixedly connected with a spheroidizing agent treatment box. A top cover is connected to the top of the processing box in an embedded mode and can be dismantled to clean the interior of the mould main body and eliminate a failure of an internal device conveniently. An extraction fan facilitates to draw fresh air from the outside into the mould main body and discharge internal exhaust gas of the casting. A cooling box makes the casting in the forming mould be cooled quickly and improves the quality of the casting greatly. The mould for the spheroidal graphite iron castingis convenient to use, has high security, is suitable for the technical field of spheroidal graphite iron, and has broad prospects for development in the future.

Description

technical field [0001] The invention relates to the technical field of ductile iron castings, in particular to a mold for ductile iron castings. Background technique [0002] Ductile iron is a high-strength cast iron material developed in the 1950s. Its comprehensive performance is close to that of steel. It is based on its excellent performance that it has been successfully used to cast some complex stress, strength, toughness, and durability. For parts with high abrasiveness requirements, nodular cast iron has rapidly developed into a widely used cast iron material second only to gray cast iron. The so-called "substituting iron for steel" mainly refers to nodular cast iron. Spheroidal graphite cast iron is obtained through spheroidization and inoculation treatment, which effectively improves the mechanical properties of cast iron, especially improves plasticity and toughness, thereby obtaining higher strength than carbon steel. [0003] However, the existing ductile iron ...
