Description

Technical Field

[0001] This invention relates to the field of injection molding machine technology, and more particularly to an injection molding device for bottle cap production. Background Technology

[0002] Bottle caps are devices used to seal bottle openings. They achieve leak-proof and anti-theft functions through structures such as threads, sealing rings, and side sealing rings. Common types include screw caps, easy-open caps, and claw caps, and are widely used in the packaging of beverages, food, pharmaceuticals, and chemical products. Their core functions include maintaining airtightness, preventing contamination, and improving transportation safety. Some smart caps also feature anti-tampering or child-safe opening designs. It should be noted that during bottle cap production, materials are fed through the feed cylinder of an injection molding machine, then the punch and die are combined, and batch injection molding is performed. After injection molding, the mold is opened, allowing multiple bottle caps to be demolded, completing the bottle cap production process.

[0003] However, during the production of bottle caps, problems such as short shots and material shortages can occur due to insufficient injection pressure, speed, or low melt temperature. This can easily result in the bottle cap material not completely filling the mold cavity. However, because the production speed is fast, workers cannot detect these problems in time, resulting in the production of a large number of incomplete or undersized products. This leads to a high product defect rate, which not only affects the production quality of bottle caps but also causes a large amount of material waste. Summary of the Invention

[0004] The purpose of this invention is to provide an injection molding apparatus for bottle cap production, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An injection molding apparatus for bottle cap production includes an injection molding machine tool, on which a feed cylinder, a die, and a punch are mounted. A feed pipe is connected to the feed cylinder and the feed pipe is connected to the injection molding machine tool. A discharge port is provided on the injection molding machine tool.

[0007] It also includes a support and pushing device, which is installed on the injection molding machine tool and is used to push multiple bottle caps into the discharge port; the support and pushing device includes a material carrier plate, which is movably installed on the injection molding machine tool, a pushing cylinder is installed on the injection molding machine tool, a pushing rod is installed on the pushing cylinder, an adapter plate is installed on the pushing rod, and a pushing plate for pushing bottle caps is movably installed on the adapter plate, and an emergency stop switch is installed on the pushing plate, which is electrically connected to the injection molding machine tool;

[0008] The supporting pusher is equipped with a synchronous scraping device, which is used to scrape the surfaces of the die and the punch. The synchronous scraping device includes two scraping seats, both of which are mounted on the pusher plate. Wedge-shaped scrapers are movably mounted on both scraping seats, and the two wedge-shaped scrapers are moved to scrape the surfaces of the die and the punch.

[0009] It also includes a linkage material cutting device, which is installed on the feed cylinder and is used to block the feed cylinder; the linkage material cutting device includes a linkage lifting frame, which is movably installed on the feed cylinder, and a blocking head is installed on the linkage lifting frame, which is used to block the feed cylinder.

[0010] Furthermore, in a preferred embodiment of the present invention, the supporting and pushing device further includes two supporting rods, both of which are installed on the bottom side of the material carrier plate, and two supporting seats are installed on the injection molding machine tool, with the two supporting rods movably installed on the two supporting seats respectively;

[0012] Furthermore, in a preferred embodiment of the present invention, two push rods are installed on the push plate, and both push rods are slidably installed on the adapter plate;

[0013] Two support springs are installed on the pusher plate, and both support springs are mounted on the adapter plate.

[0014] Furthermore, in a preferred embodiment of the present invention, the synchronous scraping device further includes a trigger frame, a pull-down groove is provided on the push plate, the trigger frame is slidably installed in the pull-down groove, and the trigger frame moves down to trigger the emergency stop switch;

[0015] A pull-down spring is installed on the inner wall of the pull-down groove, and the pull-down spring is mounted on the trigger frame.

[0016] Furthermore, in a preferred embodiment of the present invention, a locking frame is slidably mounted on the pusher plate, and a locking slot is provided on the trigger frame, with the locking frame inserted into the locking slot;

[0017] Two support shafts are installed on the pusher plate, and a release lever is rotatably mounted on the support shaft. The release lever rotates to push the locking frame out of the locking slot.

[0018] Furthermore, in a preferred embodiment of the present invention, a drive push bar is movably mounted on one side of each of the two scraping seats, and the drive push bar moves to push the disengagement lever to rotate;

[0019] Multiple connecting push rods are installed on the wedge-shaped scraper, and all of the connecting push rods are mounted on the drive push bar.

[0020] Furthermore, in a preferred embodiment of the present invention, a plurality of compression springs are installed on the wedge-shaped scraper, and the plurality of compression springs are all installed on the inner wall of the scraping seat.

[0021] Furthermore, in a preferred embodiment of the present invention, the linkage material cutting device further includes a linkage adapter frame, which is movably mounted on the injection molding machine tool;

[0022] The linkage lifting frame is installed on the linkage adapter frame. The linkage adapter frame moves downward, driving the blocking head downward through the linkage lifting frame, which is used to block the feed cylinder.

[0023] Furthermore, in a preferred embodiment of the present invention, a lifting groove is provided on one side of the feed cylinder, and the linkage lifting frame is slidably installed in the lifting groove;

[0024] A lifting spring is installed on the inner wall of the lifting slide, and the lifting spring is installed on the linkage lifting frame.

[0025] Furthermore, in a preferred embodiment of the present invention, two limiting sliding holes are provided on the adapter plate, and a limiting slide is slidably installed in each of the two limiting sliding holes. The downward movement of the limiting slide pushes the linkage adapter downward.

[0026] Both sides of the pusher plate are rotatably mounted with adapter push rods, and the two adapter push rods are respectively movably mounted on the two limiting slides;

[0027] Two adapter push shafts are rotatably mounted on the adapter push rod. One adapter push shaft is mounted on the push plate. A downward sliding hole is provided on the limiting slide. The other adapter push shaft is movably mounted in the downward sliding hole.

[0028] The beneficial effects of the injection molding device for bottle cap production proposed in this invention are:

[0029] In this invention, by setting up a feeding device, when the die and punch are separated, if problems such as short shot or material shortage occur when multiple bottle caps fall onto the carrier plate, causing the weight of the bottle caps to be insufficient, the carrier plate cannot move under the feeding plate. At this time, the feeding plate is blocked by the carrier plate, causing the feeding plate to retract. At the same time, the feeding plate drives the emergency stop switch to contact the adapter plate, causing the emergency stop switch to be triggered by the adapter plate, thereby causing the injection molding machine to stop suddenly, avoiding affecting the production quality of subsequent bottle caps.

[0030] Furthermore, in this invention, by setting up a synchronous scraping device, when the pusher plate pushes the material, two scraping seats drive two wedge-shaped scrapers to move and scrape the surfaces of the concave and convex molds to avoid plastic adhesion residue. In addition, if a bottle cap demolding failure occurs, causing the bottle cap to remain on the concave or convex mold, or if plastic that cannot be scraped is encountered, the wedge-shaped scrapers are squeezed and retracted. The wedge-shaped scrapers drive the drive pusher to move through multiple connecting push rods. The drive pusher pushes the release lever to rotate. The release lever rotates on the support shaft, causing the release lever to drive the locking frame to disengage from the locking slot. At this time, under the return force of the pull-down spring, the trigger frame is pulled down and the emergency stop switch is triggered, causing the injection molding machine to stop suddenly, which can also avoid affecting the production quality of subsequent bottle caps.

[0031] Furthermore, in this invention, by setting up a linkage material cutting device, when the pusher plate retracts, it can drive the transfer push rod to rotate, or when the trigger frame moves down, it can also drive the transfer push rod to rotate. The transfer push rod drives the restricting slide to move, so that the restricting slide moves vertically in the restricting slide hole. At the same time, the transfer push shaft slides in the pressing slide hole, and the downward movement of the restricting slide squeezes the linkage transfer frame to move, so that the linkage transfer frame drives the linkage lifting frame to move. The linkage lifting frame drives the blocking head to block the feed cylinder, so as to avoid the problem of continuous feeding and waste of raw materials when there is a problem with injection molding.

[0050] Please refer to the attached instruction manual. Figures 1-11 The present invention provides an injection molding device for bottle cap production, which includes an injection molding machine tool 1, a feed cylinder 2, a die 3 and a punch 4 installed on the injection molding machine tool 1, a feed pipe 6 connected to the feed cylinder 2, the feed pipe 6 being connected to the injection molding machine tool 1, and a discharge port 5 opened on the injection molding machine tool 1.

[0051] Further, please refer to the appendix to the instruction manual. Figures 3-7The present invention provides an injection molding device for bottle cap production, which further includes a support and pusher device 7. The support and pusher device 7 is installed on the injection molding machine tool 1 and is used to push multiple bottle caps into the discharge port 5. Specifically, the support and pusher device 7 includes a material carrier plate 701, which is movably installed on the injection molding machine tool 1. A pusher cylinder 704 is installed on the injection molding machine tool 1, a pusher rod 705 is installed on the pusher cylinder 704, a transition plate 708 is installed on the pusher rod 705, and a pusher plate 706 for pushing bottle caps is movably installed on the transition plate 708. An emergency stop switch 711 is installed on the pusher plate 706 and is electrically connected to the injection molding machine tool 1. It should be noted that in this embodiment of the invention, when the bottle caps are demolded, multiple bottle caps fall onto the carrier plate 701. If the weight of the bottle caps is insufficient, the carrier plate 701 cannot move below the pusher plate 706. At this time, the pusher plate 706 is blocked by the carrier plate 701 when pushing the material, which causes the pusher plate 706 to retract. The pusher plate 706 slides horizontally on the adapter plate 708 through two push rods 709, and the two support springs 710 are subjected to force. At the same time, the pusher plate 706 drives the emergency stop switch 711 to contact the adapter plate 708, so that the emergency stop switch 711 is triggered by the adapter plate 708, thereby causing the injection molding machine tool 1 to stop suddenly, so as to avoid affecting the production quality of subsequent bottle caps.

[0052] More specifically, in this embodiment of the invention, a synchronous scraping device 8 is installed on the feeding device 7. The synchronous scraping device 8 is used to scrape the surfaces of the die 3 and the punch 4. The synchronous scraping device 8 includes two scraping seats 801, both of which are mounted on the feeding plate 706. A wedge-shaped scraper 802 is movably mounted on each of the two scraping seats 801. The two wedge-shaped scrapers 802 move to scrape the surfaces of the die 3 and the punch 4. It should be noted that in this embodiment of the invention, when the feeding plate 706 pushes the material, the two scraping seats 801 drive the two wedge-shaped scrapers 802 to move, scraping the surfaces of the die 3 and the punch 4, thus avoiding plastic adhesion residue that could affect the subsequent production quality of bottle caps.

[0053] More specifically, in this embodiment of the invention, a linkage material cutting device 9 is also included. The linkage material cutting device 9 is installed on the feed cylinder 2 and is used to block the feed cylinder 2. The linkage material cutting device 9 includes a linkage lifting frame 901, which is movably installed on the feed cylinder 2. A blocking head 902 is installed on the linkage lifting frame 901 and is used to block the feed cylinder 2. It should be noted that in this embodiment of the invention, when a problem occurs in injection molding, the linkage lifting frame 901 drives the blocking head 902 to block the feed cylinder 2, thus avoiding the problem of continuous feeding and waste of raw materials when a problem occurs in injection molding.

[0054] Please continue to refer to the instruction manual appendix. Figures 3-7Furthermore, the injection molding device for bottle cap production provided in this embodiment of the invention includes two support rods 702, both of which are mounted on the bottom side of the material carrier plate 701. Two support seats 703 are mounted on the injection molding machine tool 1, and the two support rods 702 are movably mounted on the two support seats 703 respectively.

[0055] Furthermore, a bearing spring 707 is installed on the inner wall of the bearing seat 703, and the bearing spring 707 is mounted on the bearing rod 702. It should be noted that, in this embodiment of the invention, when the die 3 and the punch 4 separate, causing multiple bottle caps to fall onto the material carrier plate 701, the material carrier plate 701 drives the two bearing rods 702 to move within the two bearing seats 703, thereby subjecting the two bearing springs 707 to force.

[0056] More specifically, in this embodiment of the invention, two push-back slide rods 709 are installed on the pusher plate 706, and both push-back slide rods 709 are slidably mounted on the adapter plate 708; two support springs 710 are installed on the pusher plate 706, and both support springs 710 are mounted on the adapter plate 708. It should be noted that, in this embodiment of the invention, when the pusher plate 706 is blocked by the carrier plate 701, the pusher plate 706 retracts, and the pusher plate 706 slides horizontally on the adapter plate 708 via the two push-back slide rods 709, causing the two support springs 710 to be stressed.

[0057] Please refer to the instruction manual attached. Figures 3-6 and Figures 8-10 Furthermore, the injection molding device for bottle cap production provided in this embodiment of the invention includes a synchronous scraping device 8 that also includes a trigger frame 803. A pull-down groove 804 is provided on the push plate 706. The trigger frame 803 is slidably installed in the pull-down groove 804. The trigger frame 803 moves down to trigger the emergency stop switch 711.

[0058] Furthermore, a pull-down spring 805 is installed on the inner wall of the pull-down groove 804, and the pull-down spring 805 is mounted on the trigger frame 803. It should be noted that, in this embodiment of the invention, when the trigger frame 803 automatically unlocks, the pull-down spring 805 pulls the trigger frame 803 downward, thereby triggering the emergency stop switch 711.

[0059] More specifically, in this embodiment of the invention, a locking frame 806 is slidably mounted on the pusher plate 706, and a locking slot 807 is provided on the trigger frame 803, with the locking frame 806 inserted into the locking slot 807. Furthermore, two support shafts 808 are mounted on the pusher plate 706, and a release lever 809 is rotatably mounted on the support shafts 808. The release lever 809 rotates to push the locking frame 806 out of the locking slot 807. It should be noted that in this embodiment of the invention, when the wedge-shaped scraper 802 encounters adhesive, unremovable plastic, it is squeezed back and drives the drive pusher 810 to move, thereby driving the release lever 809 to rotate. The release lever 809 rotates on the support shafts 808, causing the release lever 809 to drive the locking frame 806 out of the locking slot 807, thus achieving the purpose of automatically unlocking the trigger frame 803.

[0060] Please continue to refer to the instruction manual appendix. Figures 3-6 and Figures 8-10 More specifically, in this embodiment of the invention, a drive push bar 810 is movably installed on one side of each of the two scraping seats 801, and the drive push bar 810 moves to push the disengagement lever 809 to rotate.

[0061] Furthermore, multiple connecting push rods 812 are mounted on the wedge-shaped scraper 802, and all of the connecting push rods 812 are mounted on the drive push bar 810. It should be noted that, in this embodiment of the invention, when the wedge-shaped scraper 802 encounters adhesive and unscrapeable plastic, it is squeezed and retracted, which in turn causes the wedge-shaped scraper 802 to drive the drive push bar 810 to move via the multiple connecting push rods 812, thereby driving the disengaged lever 809 to rotate.

[0062] More specifically, in this embodiment of the invention, a plurality of compression springs 811 are installed on the wedge-shaped scraper 802, and the plurality of compression springs 811 are all installed on the inner wall of the scraping seat 801. It should be noted that, in this embodiment of the invention, when the wedge-shaped scraper 802 is compressed, it drives the plurality of compression springs 811 to bear force, and under the supporting force of the plurality of compression springs 811, the two wedge-shaped scrapers 802 can abut against the surfaces of the concave die 3 and the convex die 4, ensuring the scraping effect.

[0063] Please refer to the instruction manual attached. Figures 3-6 and Figure 11Furthermore, the injection molding device for bottle cap production provided in this embodiment of the invention includes a linkage cutting device 9 that further comprises a linkage adapter 905, which is movably mounted on the injection molding machine tool 1. A linkage lifting frame 901 is mounted on the linkage adapter 905, and the linkage adapter 905 moves downward, driving the blocking head 902 downward via the linkage lifting frame 901 to block the feed cylinder 2. It should be noted that in this embodiment of the invention, when the limiting slide 906 is squeezed downward, the linkage adapter 905 is squeezed downward, thereby causing the linkage adapter 905 to drive the blocking head 902 downward via the linkage lifting frame 901, thereby achieving automatic blocking of the feed cylinder 2 by the blocking head 902.

[0064] More specifically, in this embodiment of the invention, a lifting groove 903 is provided on one side of the feed cylinder 2, and a linkage lifting frame 901 is slidably installed in the lifting groove 903; a lifting spring 904 is installed on the inner wall of the lifting groove 903, and the lifting spring 904 is installed on the linkage lifting frame 901. It should be noted that, in this embodiment of the invention, when the linkage lifting frame 901 moves, it slides vertically in the lifting groove 903, causing the lifting spring 904 to be under force. Under the rebound force of the lifting spring 904, it can help the linkage lifting frame 901 drive the blockage head 902 to reset.

[0065] Please continue to refer to the instruction manual appendix. Figures 3-6 and Figure 11 More specifically, in this embodiment of the invention, the adapter plate 708 has two limiting sliding holes 907, and a limiting slide 906 is slidably installed in each of the two limiting sliding holes 907. The limiting slide 906 moves down to push the linkage adapter 905 down; both sides of the pusher plate 706 are rotatably installed with adapter push rods 909, and the two adapter push rods 909 are respectively movably installed on the two limiting slides 906.

[0066] In addition, two adapter push shafts 910 are rotatably mounted on the adapter push rod 909. One adapter push shaft 910 is mounted on the push plate 706, and a downward sliding hole 908 is opened on the limiting slide 906. The other adapter push shaft 910 is movably mounted in the downward sliding hole 908. It should be noted that in this embodiment of the invention, when the pusher plate 706 retracts, it can drive the adapter push rod 909 to rotate, or when the trigger frame 803 moves down, it can also drive the adapter push rod 909 to rotate, so that the adapter push rod 909 rotates on an adapter push shaft 910. The rotation of the adapter push rod 909 drives the limiting slide 906 to move through another adapter push shaft 910, so that the limiting slide 906 moves vertically in the limiting slide hole 907. At the same time, the adapter push shaft 910 slides in the pressing slide hole 908, and the downward movement of the limiting slide 906 squeezes the linkage adapter frame 905 to move, so that the linkage adapter frame 905 drives the linkage lifting frame 901 to move. The linkage lifting frame 901 drives the blocking head 902 to block the feed cylinder 2, thereby achieving the purpose of automatic material cutting off.

[0067] In summary, the working principle of the injection molding device for bottle cap production provided in this embodiment of the invention is as follows:

[0068] When the die 3 and the punch 4 separate, causing multiple bottle caps to fall onto the carrier plate 701, the carrier plate 701 drives the two support rods 702 to move within the two support seats 703, and causes the two support springs 707 to be stressed, causing the carrier plate 701 to move down to below the pusher plate 706. At this time, the pusher cylinder 704 is activated, causing the pusher rod 705 to drive the adapter plate 708 to move. The movement of the adapter plate 708 drives the pusher plate 706 to move through the two pusher slide rods 709. The pusher plate 706 pushes the multiple bottle caps to the discharge port 5 for discharge. It should be noted that if problems such as short shot or material shortage occur, causing the bottle cap weight to be below the standard, the carrier plate 701 cannot move under the pusher plate 706. At this time, the pusher plate 706 is blocked by the carrier plate 701 when pushing the material, causing the pusher plate 706 to retract. The pusher plate 706 slides horizontally on the adapter plate 708 through two pusher slide rods 709, and the two support springs 710 are stressed. At the same time, the pusher plate 706 drives the emergency stop switch 711 to contact the adapter plate 708, so that the emergency stop switch 711 is triggered by the adapter plate 708, thereby causing the injection molding machine tool 1 to stop suddenly, so as to avoid affecting the production quality of the subsequent bottle caps.

[0069] Furthermore, during the material ejection process by the pusher plate 706, two wedge-shaped scrapers 802 are moved by two scraper seats 801 to scrape the surfaces of the die 3 and the punch 4, preventing plastic residue from adhering. It should be noted that if a bottle cap demolding failure occurs, causing the bottle cap to remain on the die 3 or the punch 4, or if unscraped plastic is encountered, the wedge-shaped scrapers 802 are squeezed back, which in turn causes multiple compression springs 811 to be stressed. At the same time, the wedge-shaped scrapers 802 drive the drive push bar 810 to move through multiple connecting push rods 812. The drive push bar 810 pushes the release lever 809 to rotate. The release lever 809 rotates on the support shaft 808, causing the release lever 809 to drive the locking frame 806 to disengage from the locking slot 807. At this time, under the return force of the pull-down spring 805, the trigger frame 803 is pulled down and the emergency stop switch 711 is triggered, causing the injection molding machine 1 to stop suddenly, which can also avoid affecting the production quality of subsequent bottle caps.

[0070] Furthermore, when the pusher plate 706 retracts, it can drive the adapter push rod 909 to rotate, or when the trigger frame 803 moves downward, it can also drive the adapter push rod 909 to rotate. The adapter push rod 909 rotates on an adapter push shaft 910, and the rotation of the adapter push rod 909 drives the movement of the limiting slide 906 through another adapter push shaft 910. The limiting slide 906 moves vertically within the limiting slide hole 907, while the adapter push shaft 910 slides within the pressing slide hole 908. It should be noted that the downward movement of the limiting slide 906 compresses the linkage adapter frame 905 to move, and the linkage adapter frame 905 drives the linkage lifting frame 901 to move. The linkage lifting frame 901 drives the blocking head 902 to block the feed cylinder 2, thereby avoiding the problem of continuous feeding and waste of raw materials when problems occur during injection molding.
