Lost-foam casting forming machine

Abstract

The invention belongs to the technical field of forming machines, and particularly relates to a lost-foam casting forming machine. The lost-foam casting forming machine comprises a first sliding plate, a second sliding plate, a first sliding groove, a first electric push rod and a connecting column; a first supporting column is connected to the upper end of a base; a supporting table is connected with the upper end of the first supporting column; the upper end of the supporting table is connected with a second supporting column; the upper end of the second supporting column is connected with a top plate; a hydraulic cylinder is connected to the upper end of the top plate; the lower end of a piston rod of the hydraulic cylinder is connected with an upper die; the first sliding groove is formed in the upper end of the supporting table; the first sliding plate and the second sliding plate are in sliding connection with the first sliding groove, and the first sliding plate and the second sliding plate are fixedly connected with a lower die; one end of the first electric push rod is fixedly connected into a groove formed in one end of the supporting table, and the other end of the first electric push rod is fixedly connected with the first sliding plate; and the connecting column is fixedly connected between the first sliding plate and the second sliding plate. According to the lost-foam casting forming machine, the non-working time of a forming machine is reduced as much as possible in the process of not causing the damage of an expendable pattern, and the efficiency of the forming machine is improved.

Description

technical field [0001] The invention belongs to the technical field of molding machines, in particular to a moldless casting molding machine. Background technique [0002] Formless casting is first made into a foam plastic model (manually, mechanically) according to the process, coated with a special paint, dried, placed in a special sand box, filled with dry sand, compacted by three-dimensional vibration, cast in a vacuum state, and the model is air-filled. The mold disappears, the molten metal replaces the model, and the same casting as the foam plastic model is reproduced; the production process of the moldless casting has less pollution, and the casting precision is higher, and in the step of making the foam plastic model, a molding machine is usually used Cast foam into shape. [0003] For example, a Chinese patent with application number CN201610221856.0 discloses a rotatable vertical forming machine for lost foam casting, including: block lower die; the fixed bracke...
