Description

Technical Field

[0001] The present application relates to the field of injection molding technology, and in particular to a gate shearing device for injection molded parts. Background Art

[0002] Injection molding is a process in which heated molten material is injected into the mold cavity through the runner and gate, and the material is removed from the mold after cooling and solidification, forming an injection molded product with a certain shape and structure. Usually, after the injection molded product is ejected from the mold, a gate connected to the injection molded part body remains in the runner of the injection port. Since the existence of the gate will affect the normal use of the injection molded part, it needs to be cut off.

[0003] Announcement No. CN217752577U discloses a gate shearing device for automobile interior injection molding parts. A driving device is arranged on the entire device, and the output end of the driver is used to drive the threaded rod to rotate. The movable plate moves left and right on the outer surface of the threaded rod. At the same time, the movable plate moves on the outside of the limit rod to limit the position of the movable plate to avoid position deviation of the movable plate. When used in conjunction with a processing device, the shearing can be adjusted according to the position of the waste of automobile interior injection molding parts. It has a wide range of applications and is economical and applicable.

[0004] However, there are some defects in the above scheme: when shearing the clamped injection molded part in the above scheme, in order to align the shearing position, the cutting blade needs to be controlled to move horizontally forward, backward, left and right, and then move down for shearing, which greatly affects the shearing efficiency.
