Abstract
The invention discloses a mould for casting an aluminum-coated magnesium alloy composite material. The mould comprises a mould seat (1), a movable inserter (2) and a lateral clamping mechanism (3), wherein the mould seat consists of a bottom plate (7) and lateral plates (4), (5) and (6) which are connected by virtue of fastening bolts; the lateral plates (4) and (5) are provided with grooves and are in clearance fit with the movable inserter (2); the lateral plates (4) and (6) are provided with screwed holes and are connected with the lateral clamping mechanism; and the lateral clamping mechanism consists of a clamp plate and a screw pull rod which are connected with each other. By adopting the mould for casting the aluminum-coated magnesium alloy composite material, excellent attachment of the bottom and peripheral sides of an aluminum-coated box with the mould can be realized, uniform heat radiation of a composite cast ingot is realized, and burning through is effectively prevent. Furthermore, the mould has the advantages of low processing accuracy requirement for the appearance size of the aluminum-coated box, convenience for ingot detachment and the like.
Description
Technical field
The invention belongs to Mould Machining and technical field of material, relate to casting aluminum-clad magnesium alloy composite material mould, for the preparation of stratiform aluminum-clad magnesium alloy composite material ingot casting.
Background technology
Magnesium alloy is the structural metallic materials of present density minimum, have high specific strength, high ratio modulus and the superior performance advantages such as damping vibration attenuation characteristic, but the corrosion resisting property of most commercial magnesium alloys is all relatively poor, aluminium alloy is then natural to have formed dense oxide-film, corrosion resisting property is good, has simultaneously self-repair function.Therefore adopt aluminum alloy plate materials to be coated on Mg alloy surface and then can prepare the laminar composite that has simultaneously magnesium alloy and aluminium alloy capability advantage concurrently.The preparation technology of present domestic aluminum-coated magnesium alloy laminar composite mainly concentrates on hot rolling, diffusion connection aspect, successfully prepared magnesium/aluminium lamination shape composite such as the written application diffusion connecting process of Tan of Beijing Institute of Technology, Southwestern University uses hot-roll annealing technique and has succeeded in developing Al/AZ31/Al aluminum-clad magnesium plate and strip [CN 101804710 A] etc., but existing aluminum-clad magnesium alloy composite material technology of preparing remains at lumber recovery the deficiencies such as low, process parameter control difficulty.
Because the crystallization temperature of magnesium metal and aluminium approaches, can obtain the composite ingot of aluminium/metallurgical interface combination by the liquid magnesium alloy of cast melting in the aluminium box, this just requires aluminium box and mold cavity to fit tightly, so that the heat that discharges during the magnesium alloy crystallization in time conducts in the mould, therefore traditional metal die can't satisfy this requirement.
Summary of the invention
The present invention is directed to the deficiency that above-mentioned prior art exists, provide a kind of and can realize outer alclad box bottom surface and the good applying of side and mould all around, the Homogeneouslly-radiating of realization composite ingot effectively prevents the casting aluminum-clad magnesium alloy composite material mould that burns.
Casting aluminum-clad magnesium alloy composite material mould of the present invention comprises mold base, active plugboard and side-clamping mechanism.
Described mold base is connected to form the square structure of an end face opening and a lateral opening through fastening bolt by base plate and three side plates; Wherein correspondence is processed with vertical groove on the relative two sides side plate, and active plugboard inserts in wherein, the closed side opening; Be processed with screwed hole on the side plate that wherein two sides links to each other, be separately installed with a side-clamping mechanism; Described side-clamping mechanism is connected to form by clamping plate and screw putter, and clamping plate is arranged in mold base, and is parallel with the side plate of a side separately respectively, and screw putter is contained in the screwed hole on the side plate of a side separately.
Screw putter is contained in the screwed hole on the side plate.
In addition, also be connected with guide post on the clamping plate of described side-clamping mechanism, corresponding have pilot hole at side plate, and described guide post passes pilot hole, and clamping plate is led.
Mold base of the present invention, active plugboard and side-clamping mechanism adopt good iron-based or the acid bronze alloy of thermal conductivity, and the size of described mould is determined by the appearance and size of aluminum-coated magnesium alloy composite cast ingot.
Adopt the present invention to cast the aluminum-coated magnesium alloy composite cast ingot mould, can realize outer alclad box bottom surface and the good applying of side and mould all around, make the Homogeneouslly-radiating of composite ingot, effectively prevent from burning.In addition, the appearance and size requirement on machining accuracy of the external alclad box of the present invention is low, the ingot casting convenient disassembly.
