A Sand Adding Molding Method of a Mobile Rain Sand Adder

Abstract

The invention relates to a movable type deluge sand adding device and a sand-adding modeling method. The sand adding device comprises a sand storage box, a drive travelling mechanism arranged on the top part of the sand storage box, a drawing flashboard arranged on the bottom part of the sand storage box, and an air cylinder for driving the drawing flashboard to move in a reciprocating way. A plurality of sand leakage holes are distributed in a base plate of the sand storage box; the drawing flashboard is arranged on the bottom face of the base plate of the sand storage box; and sand passing holes corresponding to the sand leakage holes on the base plate are distributed in the flashboard. According to the movable type deluge sand adding device and the sand-adding modeling method provided by the invention, the number of working stations in a traditional modeling process is reduced, the number of sand storage hoppers and swing tables is reduced, the equipment structure of a modeling production line is simplified, and the equipment cost is greatly reduced. The sand adding device provided by the invention can move between a modeling station and a laminating station in a reciprocating way and works alternatively, so that not only is a limited space on the production line fully utilized, but also the production efficiency is greatly improved.

Description

technical field [0001] The invention relates to a sand adding device and a sand adding method, in particular to a mobile rain shower sand adding device and a sand adding molding method. Background technique [0002] In the lost foam casting process, the molding process has always been one of the key points and difficulties in the lost foam casting process. The process is to add bottom sand to the sand box at the bottom sand station, vibrate the bottom sand and then pour it into the sand box. Put the model in the box, and then send it to the modeling station for operations such as sand filling and vibration, and finally cover the film and add surface sand. The entire production line needs to be equipped with bottom sand storage hopper, bottom sand vibrating table, molding sand storage hopper and molding station vibrating table. The equipment investment is high, the cost is high, the entire molding process is not continuous, and the efficiency is low. Moreover, at the molding...
