Automatic horizontal extrusion device for clay sand molding

Abstract

The invention relates to the technical field of horizontal clay sand molding machines, and discloses an automatic horizontal extrusion device for clay sand molding. The automatic horizontal extrusion device for clay sand molding comprises a machine shell, wherein a balance rod is slidingly connected with the interior of the machine shell, a telescopic rod is arranged at the bottom of the balance rod, first magnetic blocks are fixedly connected with two ends of the balance rod, second magnetic blocks are arranged at the upper portions of the first magnetic blocks, surfaces of the second magnetic blocks are fixedly connected with first stop blocks, and a corresponding rotating wheel is arranged at the end, away from the balance rod, of each first stop block. According to the automatic horizontal extrusion device for clay sand molding, rollers drive first long rods to slide in the machine shell through connecting rods, thus the first long rods extrude a material into a container, when movable contacts on surfaces of control rods are in contact with fixed contacts, a conveying pump stops working, and an electrorheological fluid solution becomes solid, so that the rollers extrude second stop blocks through extension blocks, clay sand is extruded by third long rods in a horizontal direction, and thus a horizontal extrusion effect is achieved.

Description

technical field [0001] The invention relates to the technical field of clay sand horizontal molding machines, in particular to an automatic horizontal extrusion device for clay sand molding. Background technique [0002] With the continuous development of social and economic conditions, clay sand is widely used in the field of casting, which can improve the wet strength and shape performance, so it is deeply concerned and loved by manufacturers, thus driving the clay sand in the market economy. At the same time, it also drives the research and development of clay sand related equipment, including the molding machine for enveloping clay sand. [0003] At present, there are many types of clay sand molding machines on the market. Generally, they lack horizontal extrusion, and usually squeeze the sand box up and down, resulting in soft sand materials on both sides of the level, which may cause the clay sand to collapse. At the same time, there is no reminder device. By remindin...
