Piston liquid die forging casting machine

Abstract

The invention provides a piston liquid die forging casting machine which comprises a lathe bed, a top die mechanism, an outer die mechanism, outer dies, pin hole pressing heads, a chassis, an ejection mechanism and a die locking mechanism, wherein the lathe bed comprises a first workbench; the top die mechanism is connected with the lathe bed through guide columns and is positioned above the lathe bed; the outer die mechanism is mounted above the first workbench; the outer dies and the pin hole pressing heads are arranged in a matched mode, are arranged above the first workbench and are connected with the outer die mechanism; the chassis is mounted above the first workbench and is positioned between the outer dies on the left side and the right side; the ejection mechanism is mounted below the first workbench; and the die locking mechanism comprises an upper die locking mechanism and a lower die locking mechanism which are respectively distributed on the upper side and the lower side of the first workbench. According to the technical scheme, the problems that an aluminum piston liquid die forging die cannot be split left and right and a female die needs to be installed on each casting are solved, the working efficiency is improved, meanwhile, the labor intensity is reduced, multidirectional pressurization of the aluminum piston castings is achieved, the structures of all the parts of the castings are compact, and the pressure of a main cylinder is reduced.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a piston liquid die forging and casting machine. Background technique [0002] As the core component of the engine, the piston is subjected to harsh working conditions such as high temperature and high pressure in the engine. As vehicles, construction machinery, and military equipment have higher and higher requirements for power systems, the performance indicators such as engine power density and explosion pressure continue to increase, and the operating conditions of pistons are becoming more and more harsh. It is necessary to continuously develop new processes, New equipment and other technologies are used to improve the thermal load and mechanical load capacity of the piston. At the same time, in order to meet the lightweight requirements, the aluminum piston is the first choice. The liquid die forging process combines the advantages of casting and forging. Appl...

Problems solved by technology

[0003] Casting aluminum pistons by liquid die forging technology is an important application direction. However, the existing liquid die forging equipment is generally a four-column hydraulic press. The equipment structure limits the mold design to the method of inserting a die inside the overall outer mold. Each product It is necessary to repeatedly install the die, the labor intensity of the workers is high, and the efficiency is low. Only the main cylinder can be used to pressurize, and the pressure is high, resulting in a low mold life.
