Vibration device for molding machine

Abstract

The invention relates to the technical field of sand casting, in particular to a vibrating device for a molding machine, including a workbench and a vibrating device. The workbench is placed horizontally, and a hollow protrusion is arranged on the lower surface of the workbench; the vibrate device It includes four brackets, a vibrating body and five eccentric motors. The four brackets are arranged symmetrically in front, rear, left, and right centers, and horizontal bars are arranged between the front and rear brackets; the vibrating body includes a spring and two spring fixing plates. The two ends of the above-mentioned spring are respectively fixed on two spring fixing plates, and the number of vibrating bodies is five, of which four vibrating bodies are located above the brackets, and the four vibrating bodies are symmetrically installed inside the four brackets, and the remaining one vibrates The body is fixed above the horizontal bar; the five eccentric motors are respectively mounted on unfixed spring fixing plates. The invention provides a vibration device of a molding machine, which can vibrate with multiple degrees of freedom, the vibration is more uniform and efficient, and the noise generated during the working process is relatively small.

Description

technical field [0001] The invention relates to the technical field of sand casting, in particular to a vibration device for 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 with decades of history in production. In fact, the sand mechanism is relatively simple, but the compaction of the sand mold obtained by compaction is low and unevenly distributed; the compaction of the forming platen is conducive to improving the model. The uniformity of the compactness of the top and surrounding sand molds; but in general, the compactness of the sand molds obtained by compaction molding is low, especially the compactness of the sand mold parting surface is low, the resulting castings have low dimensional accuracy and poor surface quality. [0003] Clay sand metal casting is a commonly used molding metho...
