Technical Field

[0001] The utility model relates to the technical field of injection molding machines, in particular to a glue injection limiting device for an injection molding machine. Background Art

[0002] The injection molding machine's shot limiter is a device used to restrict the machine's forward or backward movement, limiting its forward and backward movement along the same path to ensure accurate docking with the mold's injection port during each injection, thereby ensuring product quality and stability. This device typically consists of a threaded column and a guide mechanism. The stability of the threaded column and guide mechanism directly affects the accuracy of the injection molding machine's shot.

[0003] The traditional injection molding machine's injection limit device is prone to dust on the guide mechanism or threaded column after long-term use.
