Vibration table for spheroidal graphite cast iron casting molding

Abstract

The invention discloses a vibration table for spheroidal graphite cast iron casting molding and belongs to the field of spheroidal graphite cast iron. The vibration table comprises a bottom plate, wherein a plurality of second guide columns are mounted in the middle of the upper part of the bottom plate, third springs are mounted outside the second guide columns, a second shock absorbing plate isfixedly connected above the third springs, a plurality of first guide columns are fixedly connected above the second shock absorbing plate, second springs are mounted outside the first guide columns,a first shock absorbing plate is fixedly connected above the second springs, a casting box is fixedly connected above the first shock absorbing plate, a collecting box is mounted outside the casting box, and a plurality of hole plugs are mounted at the bottom of the collecting box. By arranging the second and third shock absorbing springs, a shock-absorbing and buffering role is played when a pressing plate extrudes resin sand in the casting box, so that the vibration table is good in shock absorption and is unlikely to damage equipment. The vibration table is simple in structure, good in shock absorbing effect and high in practicality and is worth being applied and popularized.

Description

technical field [0001] The invention relates to the field of ductile iron castings, in particular to a vibrating table for modeling ductile iron castings. Background technique [0002] Ductile cast 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 wear resistance. For parts with high performance requirements, nodular cast iron has rapidly developed into a cast iron material that is second only to gray cast iron and is widely used. Ductile cast iron needs to use a vibrating table during the casting process. [0003] The existing Chinese patent application publication number CN110788284A discloses a vibrating table for ductile iron casting molding, including a bottom plate and a table body; The left and right sides of the box are fixedly connected to the table body through e...

Problems solved by technology

[0004] Although the above-mentioned invention can squeeze the resin sand inside the box body to make it compact, when the pressure plate squeezes the box body, it cannot play a good shock absorption effect, and it is easy to damage the equipment. Sputtering is easy to occur when it is used, it will pollute the workbench and it is not easy to clean
