Abstract

The invention discloses a horizontal sand-ejecting and parting clay-bonded sand automatic moulding machine. The upper sand box and lower sand box are both provided with a vertically-installed horizontally-ejecting type sand-ejecting cylinder. The damage to the moulding machine during the overturning process of the moulding sand box is avoided. The upper sand box and the lower sand box are both provided with a hydraulic servo high-frequency vibration oil cylinder. The upper sand box sand-ejecting cylinder and the lower sand box sand-ejecting cylinder are both designed to be a middle-hinged swing mechanism. The sand ejecting opening of the sand-ejecting cylinder and the corresponding sand inlet in the sand box can be precisely, stably, and reliably combined or separated by controlling the swing cylinders of the upper sand box and the lower sand box.

Description

technical field [0001] The invention relates to casting molding equipment, in particular to a fully automatic molding machine for clay sand with horizontal sand injection and horizontal parting. It is mainly used in the production of wet physical hardening clay sand molds for casting. [0002] A fully automatic high-speed horizontal parting molding machine equipped with double-shot sand cylinders and adopting proportional and servo-hydraulic control technology. Background technique [0003] Metal casting molding with clay sand is one of the main production methods of mechanical parts blanks. It is widely used in the machinery manufacturing industry and occupies an important position. Among them, the production of clay sand sand mold is one of the key links in the casting production process. The quality of sand mold production is directly related to the product quality and yield of castings. At present, wet physical hardening clay sand molding is the most widely used domesti...
