Abstract

This invention relates to the field of computer casing injection molding technology, particularly to an automated feeding device for laptop casing injection molding. The device includes a screw injection molding machine with multiple dryers on one side. A batching mechanism is located at the rear of one of the dryers. The batching mechanism has multiple storage chambers, each rotatably connected to a stirring assembly. Suction pipes are connected to the storage chambers, and an adjusting assembly is located between two suction pipes. The adjusting assembly includes a guide rail, the bottom of which is fixedly connected to the top surface of the batching mechanism. Multiple movable blocks are slidably connected to the guide rail. Multiple first cylinders are mounted on the top surface of the batching mechanism, and push blocks are fixedly connected to the piston rods of the first cylinders. This device facilitates the categorized storage of different types and proportions of injection molding raw materials, allows for convenient switching of raw material suction paths, reduces material mixing, and improves the continuity and efficiency of multi-material feeding, drying, and delivery, thus meeting the diverse injection molding production needs of laptop casings.
