Description

Technical Field

[0002] Metal powder injection molding (MIM) technology is a new near-net molding technology. It is a product of the mutual penetration and intersection of multiple disciplines such as plastic injection molding technology, polymer chemistry, powder metallurgy technology and metal materials science. It can use molds to inject molded blanks and quickly manufacture high-density, high-precision, high-strength, three-dimensional complex-shaped structural parts through sintering. Especially some small parts with complex shapes that are difficult to process or difficult to process using machining and other process methods can be easily completed by MIM technology, and it has the advantages of low cost, high efficiency, good consistency, etc., and it is easy to form mass production. It is known as "the most popular component molding technology today". The metal powder injection molding process includes mixing, injection molding, degreasing, sintering and shaping processes. Shaping is to grind and shape the burrs and uneven corners on the surface of MIM parts. At present, some MIM parts with complex structures are mostly polished by a grinder equipped with a grinding stone. When the grinder is finished, the MIM workpiece will be mixed with the grinding stone. At this time, the grinding stone needs to be separated from the MIM part.

Then, use a rubber spatula to manually pour the mixture into the separation feed box 260. The mixture can slide obliquely downward on the separation feed box 260. The grinding stone is not sucked onto the first belt 330 by the first magnet 320, and the grinding stone will fall on the first separation box 270. The product on the mixture will be absorbed by the first magnet 320 on the first transmission wheel 310 on the first belt 330 for transmission. The function of the first blocking belt 340 is to prevent the product from falling out from the side. The large product that is not absorbed on the second belt 440 falls into the second separation box 350, completing the separation of the first product. The remaining small product is sucked onto the second belt 440 by the second magnet 420, and then falls into the third separation box 450, completing the secondary separation.
