Detailed Description
As shown in fig. 2, 5-8, the utility model relates to a bury injection mold's demoulding structure, including fixed die plate 1, movable mould board 2, movable mould inserts slider 3, ejector pin 4, slide rail 5, interior core-pulling son 6, roof 7 and movable mould bedplate 8.
The fixed die plate 1 and the movable die plate 2 are arranged oppositely, the lower part of the movable die insert sliding block 3 is movably sleeved in a movable sliding block groove 11 of the movable die plate 1, the lower end of the movable die insert sliding block 3 abuts against the upper end 4 of the ejector rod, the lower end of the ejector rod 4 is fixed on a top plate 7, the top plate 7 is arranged between the movable die plate 2 and a movable die base plate 8, the upper part of the movable die insert sliding block 3 extends into the die cavity, the upper part of the movable die insert sliding block 3 is provided with a fixing hole or a groove 31 for inserting the insert 100, the inner end gap of the inner core puller 6 penetrates through the movable die insert sliding block 3 and then extends into the die cavity, the outer end of the inner core puller 6 is connected to a sliding rail 5 in a sliding mode, and the sliding rail 5 is fixed on the movable die plate 2. In this embodiment, the slide rail 5 is provided with a T-shaped groove 51, and the upper end of the T-shaped groove 51 is open; the outer end of the inner core puller 6 is a T-shaped block 61, the T-shaped block 61 at the outer end of the inner core puller 6 is slidably connected in a T-shaped groove 51 of the slide rail 5, and the T-shaped groove 51 is obliquely arranged (as shown in FIG. 7).
