Large drawing and overturning molding box closer

Abstract

The invention belongs to the technical field of casting, relating to a large drawing and overturning molding box closer. A lead rail is mounted on a fixed framework on which a mobile frame is placed and slides horizontally; a limiting baffle is mounted on the right side of the fixed framework for limiting the sliding position of the mobile frame; a hydraulic lifting mechanism is mounted on the mobile frame and is connected with a hydraulic extensible mechanism and can lift and drop the hydraulic extensible mechanism. A mechanical hand is mounted on the hydraulic extensible mechanism for supporting and releasing the molding flask. A rotary motor is mounted on the mechanical hand to control the rotation of the mechanical hand. The invention is controlled by the all-hydraulic system and has good work coordination, safety and reliability and high precision of functional actions such as drawing, overturning and mould closing. The invention has the advantages of greatly simplified operation sequences and high degree of automation, thereby lightening the labor intensity and enhancing the mechanic production capacity and the machining accuracy of casting production line.

Description

technical field [0001] The invention belongs to the technical field of casting, and relates to a device for mold-drawing, turning over and box-closing after molding of a sand box in casting production, in particular to a large-scale mold-lifting and box-closing machine. Background technique [0002] At present, in the process of casting production, with the continuous development of the foundry industry and the continuous improvement of production capacity, the degree of mechanized production of casting is also continuously increased; The box is the technical guarantee for the forming accuracy of the molded box. In the prior art, the precision of the large-scale sand box is low, and the quality of the casting is poor. Due to the limitations of the functions of mechanical equipment, the original manipulator only has the functions of clamping and flipping, and the lifting and transformation are completed by driving in the workshop. In the production process, the working condi...

In the prior art, the precision of the large sand box is low, and the quality of the casting is poor

Due to the limitations of the functions of mechanical equipment, the original manipulator only has the functions of clamping and flipping, and the lifting and transformation are completed by driving in the workshop. In the production process, the working conditions are tense, and it also affects the accuracy of the casting mold.
