A sand mold rail casting device

Abstract

The invention discloses a rail-type pouring device for sand casting molds, which includes a bottom rail, a positioning rail and a pouring car. The pouring car moves linearly on the bottom rail through rollers at the bottom. The positioning device on the position on the bottom rail, the positioning device and the positioning rail cooperate to achieve the positioning function; the pouring car is composed of a car bottom plate, rollers and push rods. The orbital pouring device for sand mold casting adopts a double-layer internal vacuum insulation structure rotating cylinder to place the pouring container filled with molten iron, which can keep the molten iron warm to the greatest extent and avoid the temperature loss of molten iron during pouring. At the same time, the device adopts winding mechanism and traction The rope is used to pull the rotating cylinder to tilt to facilitate the pouring of molten iron. It is poured into the sand mold through the telescopic groove block and pouring telescopic groove block. The phenomenon of excessive molten iron overflowing and wasting.

Description

technical field [0001] The invention relates to the technical field of foundry equipment, in particular to a sand mold rail-type pouring device. Background technique [0002] Sand casting refers to the casting method that produces castings in sand molds. Steel, iron and most non-ferrous alloy castings can be obtained by sand casting. Because the molding materials used in sand casting are cheap and easy to obtain, the casting mold is easy to manufacture, and it can adapt to the single-piece production, batch production and mass production of castings. It has been the basic process in casting production for a long time. [0003] The characteristic of sand casting is that often a ladle of molten iron needs to be poured into many sand molds, so the molten iron in the ladle needs to be poured one by one. During this process, the ladle is often not easy to move, so we can only use a manual container to hold the ladle. The molten iron is then poured into molds. Many existing met...

Problems solved by technology

Many existing methods are to manually take the container to hold the molten iron and then pour it into the mold. If the casting requires less molten iron, the pouring personnel need to move frequently, which will waste a lot of manpower. Security risks
