Abstract
The invention discloses a device and a method for realizing magnesium alloy injection molding. The device comprises an injection molding machine and a molding mold, wherein the injection molding machine comprises a screw rod injection mechanism, a hopper, a long nozzle, a movable mold fixing plate and a fixed mold fixing plate; and the molding mold comprises a movable mold frame, a movable mold core, a fixed mold frame and a fixed mold core. The device is characterized in that a feed port is formed in the center of the fixed mold core; two opening ends of the feed port are respectively communicated with a cavity and an injection end of the long nozzle; and a cooling sleeve is sleeved at the injection end of the long nozzle. Semi-solid magnesium alloy materials are creatively and directly fed into the feed port in the center of the fixed mold core by the long nozzle to enter the cavity without adopting a runner mode for feeding, so that the device has such advantages as simple structure, few wastes, low material loss, good product quality and short molding period, is safe and environment-friendly in production, and is prominent in promotion of wide application of a magnesium alloy injection molding technology in the industrial field.
Description
technical field [0001] The invention relates to a device and method for realizing magnesium alloy injection molding, and belongs to the technical field of magnesium alloy forming processing. Background technique [0002] Magnesium alloy is a low-density alloy. Compared with other pure metal materials or alloy materials, even compared with aluminum alloy, magnesium alloy is lighter in weight. At the same time, magnesium alloy also has strong vibration absorption and impact resistance. Therefore, under the requirements of quality and environmental protection, magnesium alloys are used to make automobile dashboard skeletons, seats, steering column parts, steering wheel cores, gearbox housings, and engine mounts. The shells and internal parts of etc. and electronic products have become the mainstream trend. Magnesium alloy products have begun to be used in transportation, aerospace, military products, daily necessities and other fields. Therefore, the forming and processing tech...
