Fig. 1 is the use sketch map I of the back-off shaping stripper apparatus of the utility model injection mold;
Fig. 2 is the use sketch map II of the back-off shaping stripper apparatus of the utility model injection mold.
The specific embodiment
As shown in Figure 1, injection mold is wrapped and is provided with bottom plate 1, parallels 2, male model plate 3, male model benevolence 4 and back-off shaping stripper apparatus.Parallels 2 is fixedly connected on the bottom plate 1, flexibly connects and be positioned at the top of parallels 2 between male model plate 3 and the parallels 2.Back-off shaping stripper apparatus is positioned at parallels 2 middle parts, and male model benevolence 4 is positioned at male model plate 3 and is fixedly connected with male model plate 3.Back-off shaping stripper apparatus comprises liftout plate and push rod.Liftout plate is made up of upper ejector plate 5 and following liftout plate 6, is fixedly connected through screw between upper ejector plate 5 and the following liftout plate 6.Push rod comprises push rod 7 and angled-lift splits 8 two parts.
Like Fig. 1, shown in 2, push rod 7 is straight strip, and an end is provided with flange, the other end is the T font; Push rod 7 is the diameter of this end of T font less than the diameter of shaft.Upper ejector plate 5 is provided with the T shape through hole of the flange end profile of corresponding push rod 7, and push rod 7 passes this through hole, and flange place one side receives upper ejector plate 5 restrictions, opposite side to receive down liftout plate 6 restrictions, and push rod 7 is fixed on the liftout plate the most at last.Be provided with T shape through hole in the male model plate 3, an end of angled-lift splits 8 is positioned at this big end of this through-hole diameter, and this end of T font of push rod 7 is injected at this big end of this through-hole diameter after passing this little end of the diameter of this through hole.The other end of angled-lift splits 8 is positioned at male model benevolence 4 and closely is connected with male model benevolence 4.Angled-lift splits 8 is provided with one-sided convexity at this end, and this convexity and angled-lift splits 8 main bodys are skewed.Angled-lift splits 8 is obliquely installed in male model benevolence 4, and is protruding fair with male model benevolence 4 surfaces.This end that angled-lift splits 8 is positioned at male model plate 3 is provided with T font hole, and this end of T font of push rod 7 is installed in the T font hole, and then flexibly connects between push rod 7 and the angled-lift splits 8.
During work, liftout plate moves upward, and then promotes the push rod motion.Push rod 7 vertically is arranged on the liftout plate, so push rod 7 is done motion straight up with liftout plate.Angled-lift splits 8 is after the promotion that receives push rod 7, and it moves along male model benevolence 4 obliquely, and the convexity of the other end breaks away from the injection moulding workspace on direction obliquely, releases die cavity to the notes spare of injection formed.Because angled-lift splits 8 is run through in the T font hole of angled-lift splits 8, therefore have the width identical with angled-lift splits 8, this end that push rod 7 is the T font when angled-lift splits 8 moves obliquely like this will move relative to angled-lift splits 8, still is positioned at T font hole.The effect of push rod 7 is to make on the stress point of angled-lift splits 8 to move, and has shortened the length of angled-lift splits 8; Otherwise under the assistance that does not have push rod 7, the length of angled-lift splits 8 needs lengthening, and the T shape through hole on the male model plate 3 promptly is used for the cavity that angled-lift splits 8 moves and will extends, and has so occupied very large space.And push rod 7 has been arranged, and angled-lift splits 8 length can shorten, and male model plate 3 is provided with the cavity of being convenient to angled-lift splits 8 motions can be shortened.
