Problems solved by technology

However, during the injection and glue pumping of this invention, the components such as the storage servo motor and the headstock move back and forth following the roller screw assembly. During the injection and glue pumping process, due to the excessive weight of the moving parts, the injection startup time is increased. , reducing the injection performance of the injection molding machine

Abstract

The invention discloses an electric injection device for an injection molding machine. The electric injection device comprises a screw rod which is arranged in an injection front plate in a penetrating manner and a pin roller screw rod pair, wherein the pin roller screw rod pair comprises a nut and a pin roller screw rod arranged in an injection tail plate in the penetrating manner. The electric injection device is characterized in that the tail of an injection movable plate is fixedly connected with the nut; the injection movable plate is internally and rotatably provided with a pressure transmission shaft; the front end of the pressure transmission shaft is connected with a spline shaft; the other end of the spline shaft is connected with the screw rod; an injection middle plate is internally and rotatably provided with a transmission shaft; the transmission shaft is internally sleeved with a spline sleeve; a spline pair is composed of the spline sleeve and the spline shaft. With the adoption of the spline pair, the weight of a movement part in the injection process is lightened and the injection performance of the injection molding machine is improved.

Description

technical field [0001] The invention relates to an injection device, in particular to an electric injection device for an injection molding machine. Background technique [0002] Injection molding machine is the main molding equipment for making thermoplastics or thermosetting plastics into various shapes of plastic products using plastic molding molds. Among them, the injection system of the injection molding machine is one of the most important components of the injection molding machine. In a cycle of the injection molding machine, the injection system can heat and plasticize a certain amount of plastic within a specified time, and then under a certain pressure and At high speed, the molten plastic is injected into the mold cavity by the screw. During the injection process of the injection molding machine, the power transmission device in the injection system needs to complete the injection, glue pumping and melting actions. [0003] For this reason, the Chinese inventi...
