Abstract

The invention discloses an automatic feeding and screening device for casting sand and a use method, and belongs to the technical field of casting. The device comprises a screening bin and a screw feeder, a grinding barrel is arranged at the top of the screening bin, a screen is fixedly installed inside the screening bin, a vibration motor is fixedly installed at the bottom of the screening bin, afirst discharging pipe is arranged at one end of the screening bin, a fixing plate is fixedly installed on one side of the grinding barrel, a gear motor and a first bearing seat are installed on thefixing plate, a first movable shaft is movably installed on the first bearing seat, a first synchronization wheel is installed at the top of the first movable shaft, a top plate is installed at the top of the grinding barrel, a second bearing seat is installed on the middle part of the top plate, and a second movable shaft is movably installed on the second bearing seat. According to the device, the agglomerated casting sand can be crushed, so that the occurrence that the massive casting sand rolls down into a coarse slag bin is avoided, the waste of the casting sand is reduced, and the cost of casting is reduced.

Description

technical field [0001] The invention belongs to the technical field of casting, and in particular relates to an automatic feeding and screening device for casting molding sand and a use method thereof. Background technique [0002] Casting is a relatively early metal thermal processing technology mastered by humans. It has a history of about 6,000 years. Casting is a method of casting liquid metal into a casting cavity that adapts to the shape of the part. The method of obtaining parts or blanks. The material to be cast is mostly solid but heated to liquid metal, and the material of the mold can be sand, metal or even ceramics. According to different requirements, the method used will be different. Sand is It is an extremely important mold material in the foundry industry. The molding sand can be divided into surface sand, filling sand and single sand, etc. The surface sand is a layer of molding sand that is close to the casting, and the quality requirements are high; the fi...
