EJECTION STRUCTURE CAPABLE OF AVOIDING BOUNCE OF HARD RUBBER STUB BAR

摘要

An ejection structure capable of avoiding bounce of a hard rubber stub bar (7), comprising: a die core (1), a die plate (2), and an ejection plate (3), the top surface of the die core (1) being provided with a banana gate (101), and the banana gate (101) comprising a linear portion (1011) and an arc-shaped portion (1012); an ejection insert (4), the ejection insert (4) slidably passing through the die core (1) in a direction perpendicular to the die core (1), the linear portion (1011) passing by the position of the ejection insert (4), a position on the top surface of the ejection insert (4) corresponding to the linear portion (1011) being recessed to form a first recess (401), and the bottom surface of the first recess (401) being further provided with a columnar cavity (402); and a pin (5), the pin (5) passing through the die plate (2), the upper end of the pin (5) being connected to the ejection insert (4), and the lower end of the pin (5) being fixedly connected to the ejection plate (3). The ejection structure capable of avoiding bounce of a hard rubber stub bar is provided with the columnar cavity on the ejection insert to limit the sub bar, so that bounce of the stub bar can be prevented when the hard rubber stub bar is ejected.
