Abstract
A sprue device for an injection mold includes a first part and a second part. The sprue device is sealed and water-cooled so as to reduce overall molding time. The connecting section defines spiral grooves. The second part includes a chassis and an extension from the chassis. The chassis is defined with a through hole, and two gates communicated with the through hole respectively. The spiral grooves mate with the wall of the mounting hole to form a spiral runner. The gates, the through hole, and the spiral runner communicate with each other. An injection mold using the sprue device is also described.
