Problems solved by technology

At present, the preparation technology of aluminum-clad magnesium alloy layered composite materials in China mainly focuses on hot rolling and diffusion bonding. Al/AZ31/Al-clad aluminum-magnesium strip [CN 101804710 A] has been successfully developed in the process, but the existing technology for preparing aluminum-magnesium alloy composite materials still has shortcomings such as low yield and difficult control of process parameters.

Example Embodiment

[0012] Such as figure 1 As shown, the mold includes a mold base 1, a movable insert plate 2, and a side clamping mechanism 3. The mold base 1 is connected by a bottom plate 7 and three-sided side plates 4, 5, and 6 through fastening bolts to form a square structure with a top surface opening and one side opening. The two opposite side plates 4 and 5 are correspondingly processed with vertical grooves, and the movable inserting plate 2 is inserted therein to close the side openings. Threaded holes are machined on the side plates 4 and 6 connected on both sides, and a side clamping mechanism 3 is installed respectively. The side clamping mechanism 3 is composed of a clamping plate 8 (or 9) and a threaded push rod 11. The clamping plate 8 (or 9) is located in the mold base 1, and the threaded push rod 11 is mounted on the threads of the side plates 4 and 6. In the hole. A guide rod 10 is also connected to the clamping plate, correspondingly there are guide holes on the side plat...

Abstract

The invention discloses a die for casting an aluminum-clad magnesium alloy composite material, which comprises a die seat (1), a movable insert plate (2) and a side surface clamping mechanism (3). The die seat is formed by connecting a baseplate (7) with side plates (4), (5) and (6) through fastening bolts. Grooves are processed on the side plates (4) and (5), which are in clearance fit with the movable insert plate (2), threaded holes are processed on the side plates (4) and (6), which are connected with the side surface clamping mechanism, and the side surface clamping mechanism is formed by connecting a clamping plate with a threaded push rod. By adopting the die for casting an aluminum-clad magnesium alloy composite cast ingot, the bottom surface and the peripheral side surfaces of an aluminum-clad box are well jointed with the die, uniform heat radiation of the composite cast ingot is realized, and burning through can be effectively prevented. In addition, the requirement on processing precision of dimension of the aluminum-clad box is low, and the cast ingot is convenient to detach and the like.

Description

technical field [0001] The invention belongs to the technical field of mold processing and material preparation, and relates to a mold for casting an aluminum-magnesium alloy composite material, which is used for preparing an ingot of a layered aluminum-magnesium alloy composite material. Background technique [0002] Magnesium alloy is currently the metal structure material with the smallest density, which has performance advantages such as high specific strength, high specific modulus, and superior damping and vibration reduction characteristics. However, most commercial magnesium alloys have poor corrosion resistance, while aluminum alloys have poor corrosion resistance. A relatively dense oxide film is naturally formed, which has excellent corrosion resistance and self-healing function. Therefore, the layered composite material with both the performance advantages of magnesium alloy and aluminum alloy can be prepared by coating the surface of magnesium alloy with aluminu...
