A box-dividing molding machine

Abstract

The invention relates to the technical field of sand mold casting, and concretely relates to a box division molding machine. The box division molding machine comprises a sandbox, a lower box molding device, an upper box molding device, a walk device and a push device, and the sandbox is a rectangular box body; the lower box molding device and the upper box molding device are positioned in the sandbox, the lower box molding device is positioned at the left side of the sandbox, and the upper box molding device is positioned at the right side of the sandbox; the walk device is positioned above the sandbox, the upper ends of the walk device and the lower box molding device are connected with the upper end of the upper box molding device, and the walk device is used for moving the lower box molding device and the upper box molding device; and the push device is positioned just behind the lower box molding device, and the push device is used for sending box closed sand mold to a conveyer belt and allowing the box closed sand mold to enter a next process. The box division molding machine adopting a manual coal beating machine principle realizes automatic production of box division castings, and also has the advantages of simple structure, low manufacturing cost and high production efficiency.

Description

technical field [0001] The invention relates to the technical field of sand casting, in particular to a box-dividing molding machine. Background technique [0002] The central link of sand casting is molding, and the core of the molding machine is the solid sand mechanism. The compaction molding machine is a low-speed sand-consolidating mechanism with decades of history in production. In fact, the sand mechanism is relatively simple, but the compaction of the sand mold obtained by compaction is low and unevenly distributed; the compaction of the forming platen is conducive to improving the model. The uniformity of the compactness of the top and surrounding sand molds; but in general, the compactness of the sand molds obtained by compaction molding is low, especially the compactness of the sand mold parting surface is low, the resulting castings have low dimensional accuracy and poor surface quality. [0003] Clay sand metal casting is a commonly used molding method of sand ...

Problems solved by technology

However, the linked sand box walking mechanism of a fully automatic molding machine disclosed in this patent determines that it cannot load a lot of casting sand, and it is very cumbersome to add foundry sand to the linked sand box from time to time, and because The casting sand is heavy, which causes serious wear and tear on the walking mechanism of the linked sand box; a fully automatic molding machine disclosed in this patent uses more oil cylinders, and the quality of the oil cylinders is relatively heavy, and once the pipeline connecting the oil cylinders is damaged, Very easy to cause pollution
