Description

Technical Field

[0001] The utility model relates to the technical field of injection molding machines, in particular to a pedal type sliding door driving mechanism. Background Art

[0002] With the rapid development of automobile electrification, intelligence and lightweight, electric sliding doors are becoming more and more common in automobiles. Electric sliding doors are easy to operate and can greatly improve the comfort and convenience of users. The sliding door is driven by a driving device to slide to open and close the door. The driving device is generally installed on the pedal. During the preparation process, the pedal needs to be injection molded by an injection molding machine. The working principle of the injection molding machine is similar to that of a syringe for injection. It uses the thrust of the screw (or plunger) to inject the plasticized molten state (i.e., viscous flow state) plastic into the closed mold cavity, and obtains the product after solidification and finalization.
