Problems solved by technology

Although the casting machine is equipped with two stations to improve production efficiency, it only places two independent single-mode casting structures on a workbench, and there is no mutual cooperation between the two single-modes, so the floor space is still relatively large

Abstract

The invention discloses a double-mould turnover casting machine for casting a piston, and the machine comprises a rack and a workbench, wherein a through hole is arranged at the centre of the workbench, the workbench is arranged on the central support of the rack via a rotary shaft, and a turnover oil cylinder is arranged below one end of the workbench; an external mould mechanism is arranged on the workbench, a central core mechanism is arranged below the workbench, and a top mould mechanism is arranged above the workbench; and a manipulator and an electric control device are further arranged on the rack. The double-mould turnover casting machine disclosed by the invention is reasonable in structure, small in floor area, low in cost, simple and convenient in operation, fast in replacement for fixtures and moulds, stable in running, convenient in maintenance, low in fault rate, and high in the yield of the cast piston; and the double-mould turnover casting machine has the advantages of being small in floor area, high in production efficiency, stable in process parameter, stable in product quality and the like compared with a single-working-position casting machine.

Description

technical field [0001] The invention relates to casting special equipment, in particular to a casting machine for casting piston blanks. Background technique [0002] The working environment of the foundry industry is relatively harsh, and the degree of automation is also at a low level. Especially, the working environment temperature of the workshop for casting pistons can be as high as 40°C, and the labor intensity is extremely high. When producing engine pistons, most of them use the mold casting process to produce blanks. First, the mold for casting pistons is placed on the casting machine, and then the casting operation is carried out. The mold used for casting the piston includes a top mold, a lower drawing mold, a left outer mold and a right outer mold, and the left outer mold and the right outer mold are symmetrically arranged to form the outer circle of the piston after being closed. Casting machines can be divided into single-mode casting machines and multi-mode ...
