Description

Technical Field

[0001] The utility model belongs to the technical field of advanced manufacturing and automation, and particularly relates to an automatic piece picking and cutting device based on MIM technology. Background Art

[0002] Metal powder injection molding technology, referred to as MIM technology, is a new type of powder metallurgy near-net-shape molding technology formed by introducing modern plastic injection molding technology into the field of powder metallurgy. Its basic process is: first, the solid powder and the organic binder are evenly mixed, and after granulation, they are injected into the mold cavity by an injection molding machine under the heated plastic state for curing and forming, and then the binder in the formed blank is removed by chemical or thermal decomposition methods, and finally the final product is obtained by sintering and densification. Compared with traditional processes, it has the characteristics of high precision, uniform organization, excellent performance, and low production cost. Its products are widely used in industrial fields such as electronic information engineering, biomedical equipment, office equipment, automobiles, machinery, hardware, sports equipment, watch industry, weapons and aerospace.

[0003] In order to improve production efficiency, multi-cavity injection molds are usually used in the injection molding process, so that multiple products can be produced simultaneously in one injection molding process. However, in order to reduce costs, traditional multi-cavity injection molds basically do not use in-mold hot cutting technology, that is, after multiple products are injection molded, there is a connecting part between the products, which needs to be separated through a subsequent cutting process. The existing production equipment separates the removal and cutting of products, and the two processes are completed by different equipment, which is inefficient, and the two different groups of equipment increase the equipment cost to a certain extent. Therefore, the present application provides an automatic removal and cutting device to realize the removal and cutting of products from the injection mold, which effectively improves work efficiency and reduces equipment costs.
