Abstract

The invention discloses a manufacturing method for machine tool castings. The manufacturing method comprises the following steps that region division is performed according to structures of the product castings, and metal molds in corresponding shapes are prepared according to the region division; expandable polystyrene resin beads are cured, and the cured expandable polystyrene resin beads are filled into mold cavities of the corresponding metal molds to obtain a plurality of foam models in different shapes; the multiple foam models are spliced into corresponding casting models according to the structures of the product castings; planes are scraped by using molding sand to obtain molding sand surfaces, then alcohol paint is brushed on the molding sand surfaces, and then putting into the casting models is performed; a sand box is vacuumized by using a vacuum pump, and sand grains are bonded together by virtue of the difference between the atmospheric pressure and the pressure in the casting models; and molten metal is poured until foam patterns in the sand box are gasified and disappear to form the castings. By means of the manufacturing method for the machine tool castings, the casting quality is improved, and the casting manufacturing period is shortened.

Description

Technical field [0001] The present invention relates to the field of casting equipment, and more particularly to a method of manufacturing a machine tool casting. Background technique [0002] Most of the large machine tools are specific products designed for specific customers. It is generally small batch, and their supporting parts are generally large, weight, due to cost factors, product designers tend to reduce the lumen in the castings The design is more complicated, but the quality effect of the castings prepared in this manner is poor, in view of the present invention proposes a casting casting. Inventive content [0003] It is an object of the present invention to provide a method of manufacturing a machine casting, aiming to solve the technical problem of the preparation of the quality effect of the prior art. [0004] In order to achieve the above object, the method of manufacturing a machine tool casting employed, including the following steps: regional division accor...
