Description

Technical field

[0001] The invention relates to an injection molding machine, in particular to a linear high-speed single-cylinder injection mechanism for an injection molding machine, belonging to the field of plastic machinery. Background technique

[0002] The injection mechanism is a device used by the injection molding machine to heat and plasticize the thermoplastic material and squeeze the plasticized material into the molding die. The injection mechanism of the current injection molding machine mostly adopts a double-cylinder injection structure. Two injection cylinders are symmetrically arranged between the injection front plate and the injection rear plate. The oil motor is installed on the outer wall of the injection rear plate, making the base of the injection mechanism very long. , Takes up a lot of space. In particular, the double oil cylinder consumes a lot of fuel during injection, and requires high precision to achieve the balance of the injection movement on bo...
