High-rigidity frame bed body for aluminum piston blank casting machine

Abstract

The invention discloses a high-rigidity frame bed body for an aluminum piston blank casting machine. The high-rigidity frame bed body comprises a frame bed body, an outer mold opening and closing device and a top mold opening and closing device; the outer mold opening and closing device and the top mold opening and closing device are installed on the frame bed body; the outer mold opening and closing device transversely drives an outer mold to be opened and closed; the top mold opening and closing device vertically drives a top mold to be opened and closed; the outer mold opening and closing device is composed of two outer mold oil cylinders symmetrically fixed on the left and right sides of the frame bed body; each outer mold oil cylinder is connected with a half of the outer mold; and the outer mold oil cylinders drive the left and right half outer molds to carry out horizontal motion to be relatively opened or separated from each other. The high-rigidity frame bed body has the beneficial effects that aiming to the characteristics of high pressure and high mold closing force of a high-strength and high-pressure aluminum piston blank casting machine; the high-rigidity frame bed body capable of ensuring high-strength and high-pressure aluminum piston casting production is innovatively put forward; and in addition, the welding stress is removed through shot blasting and annealing after the bed body is welded, and the processing stressed is removed through annealing after roughing, so that the use requirements are better met.

Description

technical field [0001] The invention belongs to the field of aluminum piston blank casting equipment, and relates to a high-rigidity frame bed for an aluminum piston blank casting machine. Background technique [0002] The high-strength and high-pressure aluminum piston is formed by placing a prefabricated part in the combustion chamber of the piston head, and extruding high-temperature liquid aluminum liquid into the prefabricated part under pressure to strengthen the head of the piston combustion chamber. The piston explosion pressure can reach 23MPa, which can well meet the requirements of high explosion pressure and high-power engines of major automobile companies and engine factories. [0003] The high-strength and high-pressure aluminum piston casting machine is a special casting equipment for producing high-strength and high-pressure aluminum piston blanks, which is different from the traditional gravity casting aluminum piston casting machine. The hydraulic system o...
