Problems solved by technology

However, the position of the pressure plate in the molding machine currently on the market can only be adjusted up and down, and the adjustment operation is relatively cumbersome. Since it is necessary to leave room for operations such as adding sand to the sand box and removing the mold, the pressure plate needs to be s

Abstract

The invention discloses a molding machine comprising a machine body, a work table, a rotary rocking arm, a shaking device, a sand press and a mold lifter. The work table is provided with a working plate and is horizontally arranged. The rotary rocking arm is provided with a pressing plate. The top of the machine body is provided with a rotary shaft, and the rotary rocking arm is fixedly arranged on the rotary shaft and can rotate along the rotation of the rotary shaft. The work table is arranged at one lateral end of the machine body, and the rotary rocking arm drives the pressing plate to be arranged just above the work table during the to-and-for rotation. The molding machine enables the pressing plate to horizontally rotate along the rotary rocking arm; when the molding machine adds sands into a sand tank or lifts the mold, the rotary rocking arm and the pressing plate rotate for the certain angle firstly to make the upper part of the sand tank without hampers, therefore, the pressing plate does not need to be arranged at a higher position; and when a jacking compaction operation is carried out, the pressing plate rotates above the work table and the sand tank.

Description

technical field [0001] The invention belongs to the technical field of molding sand molding, and in particular relates to a molding machine. Background technique [0002] The central link of sand casting is molding, and the core of the molding machine is the solid sand mechanism. The compaction molding machine is a low-speed sand-consolidating mechanism that has been used in production for decades. In fact, the sand mechanism is relatively simple, but the compactness of the compacted sand mold is low and the distribution is uneven; the compaction of the forming platen is conducive to improving The uniformity of the compactness of the sand mold at the top of the model and around it; but in general, the compactness of the sand mold obtained by compaction molding is low, especially the compactness of the sand parting surface is low, and the resulting castings have low dimensional accuracy and surface quality. Difference. [0003] With the development of casting production and...
