A multi-station automatic shell-making machine for coated sand

Abstract

The invention discloses a precoated sand multi-station full-automatic shell manufacturing machine and relates to casting equipment. The precoated sand multi-station full-automatic shell manufacturingmachine comprises a rotating machine seat, shell manufacturing machine bodies, an air supply device and an electricity supply device. The rotating machine seat comprises a base, a rotating platform and a gear motor. The multiple shell manufacturing machine bodies are arranged on the rotating platform. The air supply device comprises a support arranged in the center of the rotating platform. A rotatable air connector is arranged on the support and is connected with a ring-shaped air pipe. The ring-shaped air pipe communicates with the shell manufacturing machine bodies. The electricity supply device comprises an anode bar and a cathode cylinder which are arranged above the air supply device in the center of the rotating platform. The anode bar and the cathode cylinder are arranged on a power support. The anode bar is sleeved with the cathode cylinder, each of the anode bar and the cathode cylinder is connected with a ring-shaped electrode, the ring-shaped electrode is sleeved with multiple carbon brush rings, and the carbon brush rings and the shell manufacturing machine bodies are connected through wires. A heat insulation layer is arranged on the outer face of a shell manufacturing machine die, and four to eight shell manufacturing machine stations are arranged on the rotating platform. The precoated sand multi-station full-automatic shell manufacturing machine has the beneficial effects that the shell manufacturing machine can conduct automatic sand filling, position changing, heating and shell demounting.

Description

technical field [0001] The invention relates to the technical field of casting equipment, in particular to a multi-station fully automatic shell-making machine for coated sand. Background technique [0002] At present, the coated sand casting process has been widely used in the industry, but the production efficiency is not high in specific applications.
