A casting process of solid lost foam for bed castings of large horizontal machining centers

Abstract

The invention discloses a technology for casting a large horizontal machining center lathe body casting by using a full-mold lost foam. The technological process comprises the following steps that thelathe body lost foam is manufactured; flow path drying is performed on the lathe body lost foam; modeling is performed on the lost foam of the lathe body; and pouring is performed on the lost foam ofthe lathe body to form the lathe body casting. The technology has the advantages that a lost foam parting method is adopted, the lost foam is divided into a lathe body lost foam base body and a lathebody lost foam loose piece, the lathe body lost foam base body and the lathe body lost foam loose piece correspondingly undergo flow coating and then are fixed together for drying, in the modeling process, the casting technology that the lathe body lost foam base body is firstly compacted and filled with molding sand, then the lathe body lost foam loose piece is put on, and filling sand is performed continuously is adopted, so that the operation of adopting the lost foam for production of the large horizontal machining center lathe body casting becomes a reality.

Description

technical field [0001] The invention relates to a casting process of a bed of a machine tool, in particular to a casting process of a solid lost foam casting of a bed of a large horizontal machining center. Background technique [0002] Because the bed castings of large horizontal machining centers have the following characteristics: 1), the structure and shape are complex: a total of 4 guide rails in the horizontal and vertical heights, 2 cutting grooves, along the direction of the parallel guide rails, the large end of the bed has 3-4 layers Inner cavity; 2), large outline size: length * width * height = (2.5-3.3m) * (1.5-2.4m) * (0.9-1.2m); 3), heavy single weight: 4-9T; therefore In the current casting process, the process of using furan resin sand solid lost foam is very difficult to produce, and the relevant written information on successful production is rare. Contents of the invention [0003] The object of the present invention is to provide a casting process of ...
