Description

Technical Field

[0001] The utility model relates to a movable roller type casting machine, belonging to the technical field of casting machines. Background Art

[0002] Iron mold sand-coated casting is one of the important casting processes in modern industry. The casting mold is formed by covering the inner cavity of the metal mold with a thin layer of coated sand, so the casting mold has good rigidity, dense structure and stable size. A variety of related equipment has been developed in the industry for removing castings. For example, the Chinese utility model patent with authorization announcement number CN105108113B discloses a box dividing, ejector and casting machine, and specifically discloses a main frame, a lifting cylinder, a guide rod support, an ejector plate frame, a roller frame, an ejector plate, a cross brace, a casting push cylinder, a push plate, multiple guide rods, multiple rollers and multiple upper box hooks. The main frame includes a base, a column and an upper beam. The lifting cylinder and the guide rod support are both on the base. There are multiple guide rods in the guide rod support. The ejector plate frame, the lifting cylinder piston end and the guide rod flange end are all fixed on the roller frame. The ejector plate is fixed on the ejector plate frame. There are multiple ejectors on the ejector plate. There are multiple rollers on the roller frame. The cross brace is fixedly connected to the column. The casting push cylinder is mounted on the cross brace. There is a push plate at the head end of the casting push cylinder. The upper box hook is fixed to the lower bottom surface of the upper beam. This solution separates the upper sand box from the lower sand box, uses an ejector to push out the residual sand and castings, and then uses a push plate to push them out of the equipment. This allows the residual sand to scatter around the equipment, and the castings to collide with each other when they fall, which may cause deformation of the castings. Utility Model Content
