Sand box fixing device of molding sand pressing equipment

Abstract

The invention discloses a sand box fixing device of molding sand pressing equipment. The sand box fixing device comprises a rack, wherein a fixed die of a quadrilateral structure is arranged above therack, fixed pressing plates are respectively arranged on four inner side walls of the fixed die, guide posts are arranged between the fixed pressing plates and the inner side walls of the fixed die,and compression springs sleeve the guide posts; electromagnets are respectively arranged on the inner side walls of the fixed die, and iron blocks which correspond to the electromagnets are arranged on the inner side walls of the fixed pressing plates; rubber layers are arranged on the outer side surfaces of the fixed pressing plates, and friction grains are formed on the surfaces of the rubber layers; and a sand box moving mechanism is arranged at the bottom in the fixed die. The sand box fixing device has the characteristics that the sand box clamping quality can be effectively increased, the compaction effect can be improved, and the molding sand compaction efficiency can be improved.

Description

technical field [0001] The invention relates to a molding sand processing device, in particular to a sand box fixing device of molding sand pressing equipment. Background technique [0002] In the field of mechanical casting, it is necessary to use molding sand for molding. In this process, a compacting device is usually required for compacting operations. The positions of the existing compacting head and the fixing device of the sand box are fixed, and the sand box is fixed every time. The placement position will be affected by manpower, and the relative position between the placement position of the flask and the compaction head may deviate, which will affect the compaction effect of the molding sand. Moreover, the use of the existing fixing device will cause the sand box to shift during the compaction process, which will affect the quality and efficiency of compaction. Contents of the invention [0003] The object of the present invention is to provide a flask fixing d...
