Problems solved by technology

Most of the existing vibration pouring platforms use vibration motor as the vibration source. The disadvantage of the vibration motor is that it can only vibrate from one direction, resulting in incomplete vibration. Therefore, we propose a new type of casting mold vibration forming platform.

Abstract

The invention discloses a vibration forming platform for a casting mold. The platform comprises a platform base. A vibration box is arranged on the upper surface of the platform base, the vibration box is internally filled with a sand-water mixed solution, a plurality of air springs and supporting springs are fixedly connected between the vibration box and the platform base, the bottom end of theouter surface of the vibration box is fixedly connected to a tension spring, and the bottom of the tension spring is fixedly connected to the platform base. According to the vibration forming platformfor the casting mold, by arranging the inner wall of the vibration box and a plurality of vibrators on the inner bottom wall, a mold immersed into the sand-water mixed solution receives a vibration force transferred by the sand-water mixed solution as a medium all around, so that vibration is more thorough and air bubbles in the mold can collide and are discharged from a sprue gate of the mold. By arranging a heating sheet, the sand-water mixed solution in the mold is heated to prevent molten iron in the mold from being cooled quickly, so that the surface of a cooled and formed casting is smoother, and the casting quality is improved.

Description

technical field [0001] The invention relates to the technical field of casting forming equipment, in particular to a casting mold vibration forming platform. Background technique [0002] In lost foam casting, in general, there are many factors that affect the quality of the finished casting, such as the structure, shape, size of the lost foam casting itself, and the influence of the molding and pouring process in the casting process. Among them, after many castings are poured and formed, there are many pores and cracks on the surface. A large part of the reason is that the molten iron mold has been in a static state after pouring, resulting in internal air bubbles that cannot be released, pouring is incomplete, and pores appear. [0003] Therefore, after injecting the molten iron, we need to vibrate the mold to a certain extent to release the air bubbles inside, so that the molten iron can penetrate into every corner of the mold. Most of the existing vibration pouring plat...
