Description

Technical field [0001] The invention relates to the field of injection machine design, in particular to a single-cylinder injection device. Background technique [0002] Injection molding machine is also known as injection molding machine or injection machine. It is the main molding equipment for making thermoplastic or thermosetting plastics into various shapes of plastic products using molding dies. A key component of the injection molding machine is its injection mechanism. [0003] The injection mechanism of a traditional injection molding machine is generally only equipped with an injection piston. The forward or backward movement of a single injection piston is used to realize the injection and ejection actions. During the injection process, the injection piston moves backward at a slower speed and lacks The guiding device is prone to deviation or other failures, which affects the normal operation of the equipment. Summary of the invention [0004] The purpose of the presen...
