Abstract

The invention discloses an injection molding machine and an electric injection device thereof. The injection molding machine comprises a base, a pull rod set and a driving mechanism, wherein lead screw assemblies are driven by second belt wheels so as to force an injection seat to displace in the axial direction of the pull rod set; and a second synchronous belt is arranged on two adjacent secondhubs in a meshed mode. According to the injection molding machine and the electric injection device thereof, the injection speed is improved by adopting a double-motor double-screw driving mode, and the synchronism of double lead screws is improved by meshing the second synchronous belt with the two second belt wheels, so that the stability in the displacement process of the injection seat is improved, better injection quality can be achieved at higher injection speed, and meanwhile extrusion abrasion between the lead screws and the injection seat is reduced, and the service life of the deviceis prolonged.

Description

technical field [0001] The invention relates to the technical field of injection molding equipment, in particular to an injection molding machine and an electric injection device thereof. Background technique [0002] Injection molding machine is a molding equipment that uses plastic molding molds to make thermoplastic or thermosetting plastics into plastic products of various shapes. The injection system is one of the most important components of the injection molding machine. Its function is to heat and plasticize a certain amount of plastic within a specified time in a cycle of the injection molding machine. Molten plastic is injected into the mold cavity by a screw. [0003] The injection system has electric and hydraulic types according to the driving mode. Electric injection devices are currently widely used because of their better controllability and injection accuracy. During the working process of the electric injection device, the servo motor drives the lead scre...
