Description

Technical Field

[0001] The utility model relates to the technical field of feeding materials for injection molding machines, in particular to an auxiliary feeding device for injection molding machines. Background Art

[0002] Injection molding machine is a common plastic processing equipment. It forms products of desired shapes and sizes by injecting molten plastic into the mold. The plastic raw materials are evenly mixed and plasticized during the heating process to form a molten state. The molten plastic is fed into the mold through a high-pressure pump and a barrel, and then the plastic is injected into the mold through a syringe. After the mold is closed, the plastic cools and solidifies in the mold, and then the mold is opened to take out the product. The barrel is generally installed on the top of the injection molding machine. When working, the material is usually poured into the feeding barrel;

[0003] The feeding method in the prior art is usually to pour the material directly into the feeding barrel. If the material is agglomerated, these agglomerates may block the feeding barrel or affect the fluidity of the plastic during processing. During the injection molding process, the agglomerated material is difficult to be effectively melted and dispersed, which will result in incomplete molding of the plastic product or unsatisfactory surface quality.

[0004] In order to solve the above problems, the present application proposes an auxiliary feeding device for an injection molding machine. Utility Model Content
