Embodiment Construction

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

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...
