Trolley tilting mechanism for static pressure molding line

Abstract

The invention discloses a trolley tilting mechanism for a static pressure molding line. The trolley tilting mechanism comprises a foundation base, a tilting base is mounted on one side of the foundation base in a hinged mode, a limiting base is mounted on the upper portion of one side of the tilting base, a limiting roller is mounted on the upper portion of the other side of the tilting base, and two trolley rails arranged side by side are mounted on the tilting base. The trolley tilting mechanism for the static pressure molding line has the positive effects that inclined casting of a sand box is realized, the casting defects of insufficient casting, shrinkage porosity, shrinkage cavity, sand inclusion and the like in the traditional horizontal casting can be overcome, the yield is improved, and the production efficiency and the production quality of the static pressure molding line are ensured; and an oil cylinder is adopted in a tilting driving device for driving, the stability of a sand box trolley can be guaranteed while equipment completes the tilting action, the phenomena of sliding, skewing and the like of the sand box trolley on the tilting base can be avoided, the equipment structure is simplified, and the tilting positioning operation is more coherent, simpler, more convenient and more reliable.

Description

technical field [0001] The invention relates to the technical field of static pressure molding equipment, in particular to a tilting mechanism of a static pressure molding line trolley. Background technique [0002] Static pressure molding is to pre-compact the molding sand through air pre-compacting, and then perform final compaction on the molding sand through the hydraulic pressure head. The pressure of the multi-contact pressure head is provided by hydraulic pressure, and the pressure is fixed, so it is called static pressure molding. , the molding method can make the compactness of the molding sand high, and is suitable for casting molding with a high degree of automation and complicated processes. At present, the pouring method of the static pressure molding line is horizontal pouring, but in the casting process of thin-walled castings, horizontal pouring is prone to casting defects such as insufficient pouring, shrinkage porosity, shrinkage cavities, and sand inclusio...

AI Technical Summary

Problems solved by technology

At present, the pouring method of the static pressure molding line is horizontal pouring, but in the casting process of thin-walled castings, horizontal pouring is prone to casting defects such as insufficient pouring, shrinkage porosity, shrinkage cavities, and sand inclusions, and the yield is low. Seriously affect the production efficiency and production quality, and bring different degrees of trouble to the production of the static pressure molding line
