Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings.

[0025] like Figures 1-4 As shown, a fully automatic demolding mechanism for multi-hole conical plastic yarn tubes includes an upper injection mold 1 and a lower injection mold 2. A positioning and fixing template 3 and a lifting plate 4 are provided between the upper injection mold 1 and the lower injection mold 2. A plurality of conical plastic yarn tube forming inner cylinders 5 are provided on the lower injection mold 2. A sliding shrinking demolding forming component 6 is provided between the lifting plate 4 and the upper injection mold 1. The sliding shrinking demolding forming component 6 is positioned and shaped to match the conical plastic yarn tube forming inner cylinders 5. An injection diverter 7 is provided above the upper injection mold 1.

[0026] In this embodiment, before injection molding, the upper injection mold 1 and the lower injection mold 2 are brought close together, so that the positioning and fixing template 3 and the lifting plate 4 are in contact. The sliding shrink-type demolding molding component 6 and the conical plastic yarn tube forming inner cylinder 5 are closed to form a complete cavity. The molten material is injected into multiple cavities through the injection molding diverter 7. After injection molding is completed, the mold is opened, the positioning and fixing template 3 and the lifting plate 4 are separated, so that the sliding shrink-type demolding molding component 6 and the conical plastic yarn tube forming inner cylinder 5 are far apart. During the upward movement of the sliding shrink-type demolding molding component 6, the interior of the sliding shrink-type demolding molding component 6 unfolds, and the molded plastic part is released from the sliding shrink-type demolding molding component 6. There is no need for manual demolding. The demolding can be completed automatically after the mold is opened. The degree of automation is high and the labor intensity is greatly reduced.

[0027] Combination Figures 1-4 As shown, the sliding shrink-type demolding molding component 6 includes several fixed outer cylinders 8 disposed between the lifting plate 4 and the injection upper mold 1. The fixed outer cylinders 8 are provided with six molding auxiliary blocks 9 that slide and cooperate with the fixed outer cylinders 8. The molding auxiliary blocks 9 correspond to the positions of the conical plastic yarn tube molding inner cylinder 5 and are matched in shape.

[0028] Specifically, during the injection molding process, the six molding auxiliary blocks 9 are in a contracted state, which cooperates with the conical plastic yarn tube molding inner cylinder 5 to form a complete cavity for injection molding. After injection molding is completed, the mold is opened, and the six molding auxiliary blocks 9 slide down to unfold, so that the molded plastic part is separated from the six molding auxiliary blocks 9. There is no need for manual demolding. Fully automatic demolding can be completed after the mold is opened. The degree of automation is high and the intensity of manual labor is greatly reduced.

[0029] Six forming auxiliary blocks 9 are arranged in a ring array along the center point of the fixed outer cylinder 8, and the inner side of the six forming auxiliary blocks 9 is provided with several hole and groove forming protrusions 10.

[0030] In this embodiment, the hole-groove forming protrusion 10 can simultaneously form the hole structure of the conical plastic yarn tube during the injection molding process, eliminating the need for secondary processing and shortening the process.

[0031] Combination Figure 3 , Figure 4 As shown, the forming auxiliary block 9 is connected to the fixed outer cylinder 8 by a sliding connector 11.

[0032] In this embodiment, during the injection molding and mold opening process, the molding auxiliary block 9 can slide through the sliding connector 11 to achieve shrinking or unfolding.

[0033] The sliding connector 11 includes a sliding insert 12 disposed between the molding auxiliary block 9 and the fixed outer cylinder 8. The fixed outer cylinder 8 has six sliding grooves 13. One side of the sliding insert 12 is fixedly connected to the molding auxiliary block 9, and the other side is slidably engaged with the sliding groove 13.

[0034] In this embodiment, during the injection molding and mold opening process, the molding auxiliary block 9 can slide between the sliding insert 12 and the slide groove 13 to achieve the action of shrinking or unfolding.

[0035] Combination Figure 4 As shown, the lifting plate 4 is provided with a plurality of alignment through holes 14, and the alignment through holes 14 correspond to the positions of the conical plastic yarn tube forming inner cylinder 5.

[0036] In this embodiment, the alignment through hole 14 is used to align the conical plastic yarn tube forming inner cylinder 5.

[0037] The positioning and fixing template 3 is provided with several alignment protrusions 15. When the conical plastic yarn tube forming inner cylinder 5 is closed, it can pass through the alignment protrusions 15 and the alignment through holes 14 in sequence.

[0038] In this embodiment, during mold closing, the alignment protrusion 15 and the alignment through hole 14 cooperate to achieve precise mold closing.

[0039] Combination Figures 1-3 As shown, the injection molding manifold 7 includes an injection molding main plate and an injection molding manifold 16 disposed above the injection molding upper mold 1.

[0040] In this embodiment, during injection molding, the molten material is separated by the injection molding main plate and the injection molding manifold 16 and enters multiple cavities.

[0041] Combination Figures 1-3 As shown, a plurality of lifting slide rods 17 are provided between the positioning and fixing template 3 and the lifting plate 4. The lifting slide rods 17 are provided with anti-disengagement buckles 18 at both ends. The anti-disengagement buckle 18 located at the bottom of the lifting slide rod 17 abuts against the bottom of the positioning and fixing template 3, and the anti-disengagement buckle 18 located at the top of the lifting slide rod 17 abuts against the top of the lifting plate 4.

[0042] In this embodiment, during the mold opening process, the positioning and fixing template 3 and the lifting plate 4 can slide together with the lifting slide rod 17. The anti-disengagement buckle 18 can prevent the positioning and fixing template 3 and the lifting plate 4 from falling off during the mold opening process, thus playing the role of anti-disengagement and fixing.

[0043] Combination Figures 1-3 As shown, several telescopic sliding rods 19 are provided between the lifting plate 4 and the upper injection mold 1.

[0044] In this embodiment, during the mold opening process, the lifting plate 4 and the upper injection mold 1 can slide together with the telescopic slide rod 19.

[0045] The working principle of this utility model is as follows:

[0046] Before injection molding, the upper injection mold 1 and lower injection mold 2 are brought close together, so that the positioning and fixing template 3 and the lifting plate 4 are in contact. The six molding auxiliary blocks 9 and the conical plastic yarn tube forming inner cylinder 5 are closed to form a complete cavity. The molten material is separated through the injection main plate and the injection diversion plate 16 and enters multiple cavities. After injection molding is completed, the mold is opened, the positioning and fixing template 3 and the lifting plate 4 are disengaged, so that the fixed outer cylinder 8 and the conical plastic yarn tube forming inner cylinder 5 are separated. As the fixed outer cylinder 8 moves upward, the six molding auxiliary blocks 9 slide downward and unfold, releasing the molded plastic part from the six molding auxiliary blocks 9. No manual demolding is required. Fully automatic demolding can be completed after the mold is opened. The degree of automation is high, which greatly reduces the intensity of manual labor.

[0047] The groove forming protrusion 10 can simultaneously form the hole structure of the tapered plastic yarn tube during injection molding, eliminating the need for secondary processing and shortening the process.

[0048] During injection molding and mold opening, the molding auxiliary block 9 can slide between the sliding insert 12 and the slide groove 13 to achieve shrinking or unfolding.

[0049] The alignment through hole 14 is used to align the conical plastic yarn tube forming inner cylinder 5. During mold closing, the alignment protrusion 15 cooperates with the alignment through hole 14 to achieve precise mold closing.

[0050] During the mold opening process, the positioning and fixing template 3 and the lifting plate 4 can slide together with the lifting slide rod 17. The anti-disengagement buckle 18 can prevent the positioning and fixing template 3 and the lifting plate 4 from falling off during the mold opening process, and play the role of anti-disengagement and fixing. The lifting plate 4 can slide together with the injection upper mold 1 with the telescopic slide rod 19.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model.
