Injection molding machine automatic material selection system and its control system for automotive interior parts

Abstract

The injection molding machine automatic selection feeding system and its control system for automotive interior parts overcome the inability to automatically select raw materials in the prior art, the refueling process takes too long, the efficiency is low, and refueling errors are prone to occur, resulting in product failure. Scrapping, a problem that affects output and quality, is characterized by multiple dry material tanks connected to small material tanks of multiple injection molding machines through distribution valves and feed lines, and mold ID codes are installed at the mold installation end of each injection molding machine Plugs and jig ID coded plugs, PLC control system checks whether the injection molding machine and the drying material tank are short of materials and loads them through patrolling; the beneficial effect is to realize the flexibility of the feeding method, and to realize automatic selection of raw materials, reducing It eliminates human operation, effectively prevents the occurrence of wrong raw material selection for injection molding machines, realizes continuous production and monitoring functions, improves product production efficiency and product quality, has flexible feeding methods, saves energy and reduces consumption, and saves time for a single refueling. efficient.

Description

technical field [0001] The invention belongs to the technical field of industrial automation, and in particular relates to an automatic material selection system and a control system for an injection molding machine used for automotive interior parts. Background technique [0002] Injection molding machines are molding equipment that make thermoplastics or thermosetting plastics into plastic products of various shapes. The production process of plastic products is as follows: feed the raw materials into the barrel, and after the raw materials are dried, they are sent to the injection molding machine for melting and plasticization, and high pressure is applied to the molten plastic to make it inject and fill the mold cavity. In the existing technology, in the case of multiple injection molding machines, each injection molding machine is equipped with a barrel. The disadvantage of this structure is that after the raw materials in the barrel are used up, manual feeding is requi...

Problems solved by technology

However, according to the operating process disclosed in the utility model specification, the utility model is not automatically selected to supply materials from the drying dehumidifier to the photoelectric suction hopper of the injection molding machine. It needs to be preset manually, and the automation level is still relatively low. There will be errors in material selection, resulting in product scrapping

[0005] Specifically in the injection molding production of automotive interior parts, the automatic feeding system of injection molding machines in the current technology includes 4 dry material tanks and 4 injection molding machines. When feeding materials to the injection molding machines, each dry material tank is supplied to each The small material tank of each injection molding machine is used for feeding, that is, the feeding station of the injection molding machine in the prior art uses one dry material tank corresponding to one injection molding machine, and each dry material tank supplies material to the small material tank of each injection molding machine , the existing problem is;

[0008] This invention simply says that it uses PLC to control automatic feeding, which is not only convenient to operate, but also has the advantage of large processing capacity, but this invention only briefly introduces the general content, there is no clear and complete description of the content of the invention, and there is no specific disclosure of PLC. The control system does not have the function of automatically selecting the feeding material
