Description

Technical Field

[0001] The utility model relates to the technical field of mold exhaust plugs, in particular to a low-pressure strip exhaust plug with an easy-to-install exhaust structure that can be used multiple times. Background Art

[0002] At present, most low-pressure mold exhaust plugs use conventional strip exhaust plugs or conventional M-shaped exhaust columns or conventional exhaust needles or conventional exhaust needle wire-cut exhaust groove exhaust needles;

[0003] 1. When a conventional strip exhaust plug is knocked into the exhaust hole of the mold, the exhaust gap is easily squeezed together, causing the exhaust gap to be blocked or deformed, causing the exhaust gap to become larger. It is easy to enter aluminum during production and is disposable; 2. When a conventional M-shaped exhaust column is used to knock the exhaust plug, it is difficult to knock it in when the mold is cold if the exhaust plug hole is small, causing the exhaust gap to be squeezed together, affecting the exhaust effect. When the mold is cold, the exhaust plug hole is slightly larger and knocked in. After production, it is easy to fall out when the mold temperature is high, causing aluminum to enter the exhaust plug hole, affecting production; Utility Model Content
