Aluminum magnesium alloy counter-gravity casting and forming mould for auto parts production

Abstract

The invention discloses an aluminum magnesium alloy counter-gravity casting and forming mould for auto parts production. The aluminum magnesium alloy counter-gravity casting and forming mould for autoparts production comprises a bottom plate, wherein hydraulic telescopic rods are fixedly connected to four corners of the top part of the bottom plate; and an outer shell is fixedly connected to themiddle of the top part of the bottom plate. According to the aluminum magnesium alloy counter-gravity casting and forming mould for auto parts production, through the hydraulic telescopic rods, a lower mould and an upper mould are pressed and closed favorably; through an electric telescopic rod, a bearing plate and a top block, the lower mould can be taken out favorably; through threaded support rods, support rod holes and baffle rings, the lower mould can be fixed favorably; through a clamped sealing ring and an annular clamping groove, the sealability of the lower mould and the upper mould is further improved; through the outer shell, a water suction pump, a corner water outlet pipe and a corner water suction pipe, a casting piece can be cooled favorably; through an air suction pump, a corner air pipe, a fixing ring, a corner valve pipe and a flexible pipe, the additional resistance is adjusted; through an upper mould groove, screw hole blocks and bolts, the upper mould is fixed; andmeanwhile, through the threaded support rods and bolts, the lower mould and the upper mould are replaced, so that different casting pieces can be conveniently processed.

Description

technical field [0001] The invention relates to the technical field of auto parts production, in particular to an aluminum-magnesium alloy anti-gravity casting mold for auto parts production. Background technique [0002] Anti-gravity casting is a method that makes metal fill the mold from bottom to top against gravity and other resistances under the action of pressure, and obtain castings under pressure. Anti-gravity casting technology refers to the driving force and The direction of gravity is opposite, and the molten metal flows in the opposite direction of gravity. In anti-gravity casting, the molten metal is actually filled under the combined action of gravity and the external driving force. Due to the existence of the external driving force, the casting reduces shrinkage and porosity. Casting defects such as pinholes and pinholes are widely used in the production of auto parts made of aluminum-magnesium alloys. However, the existing casting molds have low cooling effic...
