Abstract

The invention discloses an all-electric ejecting-type super-speed injection molding machine which mainly comprises a mold closing mechanism, an injecting device and a rack. The injecting device comprises a nozzle, a machine cylinder, a heating ring, a screw, a feeding hopper, a hopper seat, a mobile device, a draw bar, a plastifying device, an injecting seat, an ejecting device and an ejecting seat. The nozzle, the machine cylinder, the screw, the hopper seat and the plastifying device are connected with the injecting seat sequentially in an axis aligning way. The ejecting device comprises an electromagnetic ejector and an ejecting sliding block. The tail end of the ejector is fixed on the ejecting seat and is capable of performing relative motion on an ejecting platform along with the injecting device. The ejecting sliding block slides on the electromagnetic ejector and one end of the ejecting sliding block is connected with the injecting seat. During injection, the ejecting sliding block is driven to move forwards by the electromagnetic ejector, so that the injecting seat is driven to move forward and the screw is driven to inject forwards finally. The injection molding rack has the advantages of high responsiveness, saving energy, protecting environment and the like. Thus, the problems of high energy consumption and difficulty in increasing speed of hydraulic-type super-speed injection molding machines are solved. The mechanical mechanism becomes simple and the assembly difficulty is reduced.

Description

technical field [0001] The invention relates to an injection molding machine, which belongs to the field of polymer material molding machinery. Background technique [0002] Injection molding is an important method of plastic molding. It can not only produce products with complex structures, but also has high precision, beautiful shape, high production efficiency, and wide market demand. In recent years, with the improvement of polymer material processing and molding technology, high-precision, ultra-thin plastic products have been widely used in 3C products, medical equipment, automobiles, optical components and other fields. In order to meet the molding requirements of ultra-light, ultra-thin and ultra-precision plastic products, the development of all-electric injection molding equipment with ultra-high injection speed and high injection pressure has become the focus of the plastic machine industry. [0003] Generally speaking, injection molding with an injection speed o...
