Sealing ring is provided between the core endoporus upper end.
Further, the port position of the half_split block lower end correspondence circle set plastic is provided with screw thread mold insert, the Hough
Guide pillar is provided between block and the core fixing plate.
Using above-mentioned technical proposal, due to directly releasing circle set plastic, the frustum of push rod using the center push rod with frustum
Generatrix direction processes air drain；It ensure that the normal quick mold filling of plastic melt；Go out when also avoiding releasing between circle set plastic and core
Existing vacuum causes to release difficulty, compared with the structure of common support (hot block adds supporting plate) plus push rod (or push pedal), and mould is thick
Degree reduces 40%；The mould features compact structure, reliable operation.
