Description

Technical Field

[0001] The utility model relates to a field, in particular to a split-type vent plug. Background Art

[0002] Vent plugs are used to vent lost foam during the foaming process or to seal the venting process after foaming. Existing vent plugs are typically one-piece cylindrical rubber plugs. Their production process requires first injection molding the rubber plug as a whole, and then punching holes in the rubber plug. However, punching holes in the rubber plug requires the use of a dedicated punching tool, and the force must be controlled. Too little force will result in an insufficient hole diameter, while too much force will damage the rubber plug. Furthermore, after punching, the hole must be cleaned with a scraper or vacuum cleaner to prevent debris from clogging the hole and affecting the performance. Therefore, the traditional vent plug punching process is very cumbersome, has low production efficiency, and is prone to damage. Utility Model Content
