Fig. 1 is a kind of two slip twice core pulling slide block mechanism structure composition schematic diagram of the present invention;
Fig. 2 is the present invention a kind of couple of mounting structure figure of slip twice core pulling slide block mechanism on mould.
Detailed description of the invention
Fig. 1, Figure 2 shows that related description figure of the present invention;
A kind of two slip twice core pulling slide block mechanism, comprises latch segment screw 1, latch segment 2, sliding block stop screw 3, wearing plate 4, the spacing hoodle 5 of sliding block, guide pillar 6, sliding block 7, centre tunnel slide block 8, top shoe 9, Angle Pin 10, as shown in Figure 1.
Described sliding block 7, centre tunnel slide block 8, top shoe 9 form combined type tunnel slide block structure, centre tunnel slide block 8 is coordinated with sliding block 7 by horizontal T-slot, top shoe 9 is coordinated with centre tunnel slide block 8 by tilting T-slot, and sliding block 7, centre tunnel slide block 8, top shoe 9 slider head head form product side and take out type forming surface;
The interference of described guide pillar 6 is installed on sliding block 7, and through centre tunnel slide block 8 central hollow position, guide pillar 6 with top shoe 9 for small―gap suture is slidably matched;
Described latch segment 2 is locked inclined-plane and is divided three sections to lock sliding block 7, centre tunnel slide block 8, top shoe 9 respectively;
The sliding stroke of loosing core of described sliding block 7 is controlled by sliding block stop screw 3, the spacing hoodle 5 of sliding block;
Further, for the practical application of mechanism of the present invention is described, as shown in Figure 2, auxiliary mould parts is needed to comprise impression bolster 11, die cavity mold insert 12, core mold insert 13, core fixing plate 14;
Further, for further illustrating motion control situation of the present invention, in Fig. 2, position indicated by K is the position of vertically loosing core of product, a, b, c, d, e, f represent the control point on latch segment 2, a-b section controls the compression of top shoe 9, c-d section controls the compression of centre tunnel slide block 8, and e-f section controls the compression of sliding block 7, and all the other are respectively segmented into auxiliary subsection; G, m, r represent the control point on Angle Pin 10, h is control point in sliding block 7 slanting guide pillar hole, m, n are control point in centre tunnel slide block 8 slanting guide pillar hole, s is control point in top shoe 9 guide pillar hole, t, p are control point on guide pillar 6, o is the spacing hole position on sliding block 7, and q is the spacing installation site of hoodle 5 on core fixing plate 14 of sliding block; .
During real work, as shown in Figure 2, its motion running can be divided into several step:
1) after the first core-pulling die is opened, die cavity is opened, impression bolster 11, core fixing plate 14 are separated, die cavity mold insert 12, core mold insert 13 are separated, latch segment screw 1, latch segment 2, Angle Pin 10 stay in impression bolster 11 side, and control point a, b, c, d, e, f on latch segment 2 are separated with corresponding slide body rapidly; The spacing hoodle 5 of sliding block stop screw 3, wearing plate 4, sliding block, guide pillar 6, sliding block 7, centre tunnel slide block 8, top shoe 9 are followed dynamic model and are moved together, now, in centre tunnel slide block 8 slanting guide pillar hole control point n point first with the control point r point cantact on Angle Pin 10, under the extruding of Angle Pin 10, centre tunnel slide block 8 is moved to the left along the T-slot on sliding block 7; Meanwhile, sliding block 7 is contactless with Angle Pin 10, keeps motionless; Owing to coordinating for gradient T-slot connects between centre tunnel slide block 8 with top shoe 9, the motion of centre tunnel slide block 8 will pull the motion of top shoe 9, but owing to being subject to the restriction of guide pillar 6, top shoe 9 can only move along guide pillar 6 vertical direction; Its movement tendency is that in top shoe 9 guide pillar hole, s point in control point moves from t point in control point guide pillar 6 to p point direction, and progressively complete the place of K shown in Fig. 2 product and vertically to loose core the core_pulling demoulding of position, centre tunnel slide block 8 completes the side core-pulling demoulding of its head;
2) second time is loosed core when control point in centre tunnel slide block 8 slanting guide pillar hole is from after the relative movement of n point becomes m point and r point cantact, in sliding block 7 slanting guide pillar hole, h point in control point starts and the control point g point cantact on Angle Pin 10, now, in top shoe 9 guide pillar hole, s point in control point moves to p point from t point in control point guide pillar 6, and top shoe 9 completes the place of K shown in Fig. 2 product and vertically to loose core the core_pulling demoulding of position; Subsequently, along with the continuation campaign of core fixing plate 14, Angle Pin 10 will drive sliding block 7, centre tunnel slide block 8, top shoe 9 together to left movement, until the spacing hole o point on sliding block 7 moves to the q point position at sliding block spacing hoodle 5 place, thus, complete the side core-pulling action of whole combined type tunnel slide block;
3) when resetting, process is contrary, centre tunnel slide block 8 first pushes back by Angle Pin 10, under the effect of guide pillar 6, top shoe 9 synchronous resets, then sliding block 7 pushes back by Angle Pin 10 together, is finally ensured the reset completely of sliding block 7, centre tunnel slide block 8, top shoe 9 by latch segment 2, whole mould closes, and waits for that next injection cycle starts.
The two slip twice core pulling slide block mechanism of the one adopting technique scheme to provide, when there are core_pulling demoulding needs with horizontal direction and vertical direction in plastic products side simultaneously, synchronous core_pulling demoulding can be carried out with vertical direction in the horizontal direction to it, improve injection moulding production efficiency, reduce production cost; Apparatus design is reasonable, compact conformation, and working stability is safe and reliable, easy-to-use.
Specific embodiment described herein is only to the explanation for example of the present invention's spirit, those skilled in the art can make various amendment or supplement or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present invention or surmount the scope that appended claims defines.
