Description

Technical Field

[0001] The invention relates to the technical field of casting production lines, in particular to a sand mold pressing device and a horizontal boxless casting production line thereof. Background Art

[0002] With the gradual promotion of horizontal boxless casting production lines in the foundry industry, technical difficulties such as how to compact the casting sand mold before pouring and remove the casing and weight after pouring, how to promptly and effectively remove the residual sand on the sand mold trolley surface, and how to effectively remove the residual sand attached to the casing and weight, are hindering the further development of casting production.

[0003] The horizontal flaskless casting production line uses multiple sand mold trolleys to carry the casting sand molds and arrange them on the track to push them forward one by one. During the production process, due to the continuous operation of the sand mold trolleys and the limited space, the residual sand accumulated on the sand mold trolleys is difficult to remove, which directly affects the accurate placement of the sand mold on the sand mold trolley and seriously affects the normal production of the horizontal flaskless casting production line.

[0004] In the production of horizontal boxless casting production line, in order to prevent the sand mold from lifting and misalignment during the pouring process, a sleeve box is used to lock the upper and lower sand molds before pouring to prevent the upper and lower sand molds from misalignment; at the same time, a pressure iron is used to compact the upper part of the sand mold, which can effectively avoid lifting during the pouring process. However, during the pouring process, it is inevitable that some residual sand will firmly adhere to the inner wall of the sleeve box and the compacting surface of the pressure iron, which is difficult to remove. The subsequent use of the pressure iron and sleeve box directly affects the compaction effect of the sand mold, which seriously affects the normal operation of the horizontal boxless casting production line and restricts production.

[0005] In order to solve the problems of sand mold compaction and sand mold trolley cleaning on some horizontal boxless casting production lines, technicians have set up independent device mechanisms for placing the box and iron pressure, cleaning the sand mold trolley, and offline sand mold. This technical solution occupies a large space, has high investment costs, is cumbersome to operate, and is inconvenient to operate and produce. For example, a sand mold box sand cleaning mechanism disclosed in Chinese patent CN208895135U includes a sand cleaning frame, a reciprocating arm, a cleaning brush for cleaning the inner wall of the box removed from the sand mold, and a reciprocating drive structure for driving the reciprocating arm to move. The reciprocating arm and the reciprocating drive structure are both arranged on the sand cleaning frame, and the cleaning brush is arranged on the reciprocating arm through a cleaning brush lifting structure.
