Pressing mechanism for molded sand compacting equipment

Abstract

The invention discloses a compacting mechanism for molding sand compaction equipment, which comprises a frame, a hydraulic telescopic rod is arranged at both ends above the frame, a support plate is provided at the upper end of the hydraulic telescopic rod, and a compacting mechanism is provided under the support plate. A percussion mechanism fixed on the support plate is arranged above the pressing mechanism; the percussion mechanism includes a screw rod arranged horizontally above the support plate, the screw rod is connected with a rotating motor, and guide columns are respectively provided on both sides of the screw rod. The screw rod is provided with a slide block matched with the guide column, the two ends above the slide block are respectively provided with a stepping motor and a striking rod, and the output shaft of the stepping motor is provided with an eccentric wheel matched with the striking rod; The lower end of the striking rod is provided with a striking plate located under the supporting plate, and a shock absorbing pad is arranged under the striking plate, and a return spring located between the striking plate and the supporting plate is set on the striking rod. The invention has the characteristics of improving production efficiency, reducing labor intensity of workers and improving compaction effect.

Description

technical field [0001] The invention relates to a molding sand compacting device, in particular to a compacting mechanism for molding sand compacting equipment. Background technique [0002] In the field of mechanical casting, it is necessary to use molding sand for molding. During the molding process, manual beating is usually required to realize the compaction of the molding sand. This method is not only time-consuming and laborious, but also has low production efficiency, and the compaction effect is not ideal. The product quality levels are uneven. Contents of the invention [0003] The object of the present invention is to provide a compacting mechanism for molding sand compacting equipment. The invention has the characteristics of improving production efficiency, reducing labor intensity of workers and improving compaction effect. [0004] The technical scheme of the present invention: a compacting mechanism for molding sand compaction equipment, including a frame,...
