Description

TECHNICAL FIELD

[0001] The application relates to the technical field of injection molding, in particular to an intelligent tray chip embedded injection molding device. BACKGROUND

[0002] The intelligent tray chip embedded injection molding device is a key production equipment specially developed for intelligent factories, and is mainly used for manufacturing high-load and corrosion-resistant intelligent logistics trays with embedded chips. Compared with the traditional chip assembly method, the device fundamentally solves the stability problem of chip application. If the chip is attached to the surface of the tray, the chip is completely exposed and is directly worn out by collision and friction during logistics handling. If the chip is embedded in the tray without being integrally formed with the tray, the gap is easy to enter water, dust or corrosive substances, causing the chip to short circuit and the signal to be interrupted, so that the functions of goods tracking and inventory management cannot be stably realized. In the injection molding process, the device precisely controls the injection molding parameters through customized molds, stably embeds the specially designed chip in the tray, uniformly wraps the chip with high-performance molten plastic, forms an integrated structure seamlessly connecting the chip and the tray, and relies on the selected high-mechanical-property and corrosion-resistant plastic raw materials and the optimized tray structure design to ensure that the produced tray is heavy and corrosion-resistant and can be stably used in complex environments. The intelligent tray produced by the device can realize goods tracking and intelligent inventory management through the chip, and can be connected to the factory logistics system to provide efficient support for the factory logistics link, and is an important equipment for building a modern intelligent logistics system.

[0003] In the prior art, during the chip embedding injection molding operation of the intelligent tray, the chip is first accurately placed in the preset position of the injection molding mold and fixed, then high-temperature molten plastic is injected into the mold, the plastic uniformly wraps the chip, and after the plastic cools and solidifies, the chip and the tray form a seamless integrated structure, and the chip is completely embedded in the tray. In this process, since the molten plastic has fluidity, it is easy to deviate from the preset position, causing the chip to be close to the surface of the tray, and the molded tray is easy to expose the chip due to friction and collision in use, thereby causing a chain of functional failure problems. In view of this, an intelligent tray chip embedded injection molding device is proposed. SUMMARY

[0015] Compared with the prior art, the present application has the following advantages:

[0016] 1、The present application changes the traditional tray chip embedding method, first closes the mold by the movable mold and the fixed mold to form a mold cavity with the shape of the main body of the tray, then injects molten plastic into the mold cavity, until the flowing molten plastic fills the mold cavity to form a static state, then drives the first chuck and the second chuck of the core feeding clamping assembly to clamp the plastic column by the driving assembly, and drives the plastic sleeve to pass through the core cavity head inner cavity to enter the mold cavity of the fixed mold, clamps the plastic column by the first chuck and the second chuck, makes the plastic sleeve in a suspended state in the molten plastic, that is, the main body of the chip in the inner cavity of the plastic sleeve is in a stable suspended state, until it is cooled and formed, the plastic sleeve and the plastic in the mold cavity form an integral whole, and finally the plastic column protruding from the side wall of the main body of the tray is cut off by the punching assembly, in this process, the molten plastic is first injected into the mold cavity, and then the chip is inserted into the static molten plastic to form a stable suspended state, effectively avoiding the interference of the flowing molten plastic on the position of the chip, solving the problem that the chip is easy to deviate from the preset position in the injection molding process.

[0017] 2、The chip is inserted into the molten plastic in the static state, first inserted into the chip feeding channel through the sending core cavity head of the driving assembly, in this process, the driving frame slides forward along the slide rail, on the one hand, it can drive the opening and closing positioning assembly to move forward synchronously, and make the first positioning cover and the second positioning cover move in opposite directions to form a separated state, providing space for the forward movement of the core feeding clamping assembly, on the other hand, the gear two on the inner side wall of the wheel frame rotates forward on the top of the fixed tooth plate, drives the transmission tooth plate to move forward along the slide frame at a faster speed, the transmission tooth plate pushes the push plate forward through the movable column of the end head, in this process, the core feeding clamping assembly can clamp the plastic column of the plastic sleeve, and drive the clamped plastic sleeve to move forward until the first clamp, the second clamp and the plastic sleeve enter the inner cavity of the sending core cavity head of the driving assembly and stop, at this time, the inner cavity of the sending core cavity head is blocked by the first clamp and the second clamp in the combined state and the plastic sleeve, forming a closed state, further, the sending core cavity head in the closed state is located in the chip feeding channel, so that the chip feeding channel forms a closed state, in this state, the molten plastic is injected into the cavity of the mold in the mold closing state, which can prevent the molten plastic from overflowing from the chip feeding channel, after the molten plastic fills the cavity, a static state is formed, then the sending core cavity head of the driving assembly is completely inserted into the chip feeding channel, the first clamp and the second clamp in the combined state are completely inserted into the inner cavity of the sending core cavity head, at the same time, the plastic sleeve enters the cavity and melts into the static molten plastic, at this time, the inner cavity of the sending core cavity head is still blocked by the first clamp and the second clamp, that is, the chip feeding channel still maintains a closed state, preventing the plastic sleeve from easily overflowing from the chip feeding channel during the insertion into the static molten plastic, realizing the effect that the chip feeding channel is closed throughout the process and the insertion operation can be realized, solving the problem of easy overflow of molten plastic during the injection of molten plastic into the cavity and the insertion of the chip into the static molten plastic.

[0018] 3、The driving assembly is designed, the sliding speed of the transmission tooth plate on the slide frame is superimposed with the displacement speed caused by the rotation of gear two, so that the transmission tooth plate moves forward at a faster speed, realizing the effect that the core feeding clamping assembly can complete the clamping action of the plastic column of the plastic sleeve and quickly drive the plastic sleeve to move forward to the inner cavity of the sending core cavity head during the forward movement of the driving frame, this design can ensure that the core feeding clamping assembly has accurately delivered the plastic sleeve to the specified closed position before the sending core cavity head is initially inserted into the chip feeding channel and the molten plastic is injected into the cavity, avoiding the problem of plastic sleeve delivery lag caused by insufficient transmission speed, which in turn causes the molten plastic to overflow from the chip feeding channel during injection, at the same time, it also saves the accurate timing for subsequent insertion of the chip into the static molten plastic, ensuring that the chip can be embedded in time after the molten plastic is completely static, further strengthening the stability of the chip position, effectively solving the problems of molten plastic overflow and easy deviation of the chip embedding timing.

[0051] In the initial state, the first positioning cover 701 and the second positioning cover 702 are in the merged state, receiving the plastic sleeve 10 falling from the material guide pipe 606 and positioning it; when the driving frame 904 slides forward along the slide rail one 902, it can drive the opening and closing positioning assembly 7 to move forward synchronously, the driving column 708 at the bottom of the sliding plate 707 slides forward along the guide groove 704 at the top of the guide block 703, the driving column 708 first slides in the straight groove of the guide groove 704, in this process, the opening and closing positioning assembly 7 does not change, providing time for the core feeding and clamping assembly 8 to clamp, when the core feeding and clamping assembly 8 clamps and fixes the plastic column 11 of the plastic sleeve 10, the driving column 708 enters the curved groove of the guide groove 704, affected by the curve of the curved groove, it can drive the sliding plate 707 to move along the slide rail two 910, thereby making the adjusting toothed plate 706 drive the gear three 705 meshing therewith to rotate, the gear three 705 drives the meshing gear four 709 and the coaxial gear five 710 to rotate synchronously, since the first toothed plate 711 of the first positioning cover 701 and the second toothed plate 712 of the second positioning cover 702 are respectively meshed with the gear five 710, and they slide along different guide rods 914, the rotation of the gear five 710 will drive the first toothed plate 711 and the second toothed plate 712 to move in opposite directions, making the first positioning cover 701 and the second positioning cover 702 move in opposite directions to form the separated state, after separation, when the driving frame 904 continues to slide forward along the slide rail one 902, the driving column 708 again slides into the straight groove from the curved groove of the guide groove 704, keeping the first positioning cover 701 and the second positioning cover 702 in the separated state, providing space for the core feeding and clamping assembly 8 to move forward.

[0052] As another embodiment of the present application, the core feeding and clamping assembly 8 further comprises a movable frame 803 slidingly arranged on the guide slide rail five 915, the first clamp head 801 and the second clamp head 802 are respectively slidingly arranged in the inner cavity of the movable frame 803; wherein the side wall of the movable frame 803 is rotationally arranged with a screw rod 804, the circumferential outer wall of the screw rod 804 is arranged with two opposite screw threads, the screw rod 804 is threadedly connected with the first clamp head 801 through one of the screw threads and is threadedly connected with the second clamp head 802 through the other opposite screw thread; through the rotation of the screw rod 804, the first clamp head 801 and the second clamp head 802 can be driven to move oppositely or opposingly in the inner cavity of the movable frame 803. The end of the screw rod 804 is connected with a gear six 805, the side wall of the movable frame 803 is connected with a plurality of guide cylinders 806, a push-pull rod 807 is slidingly arranged in the inner cavity of the guide cylinder 806, the push-pull rod 807 is connected with a linkage tooth plate 809 through a limiting plate 808, the linkage tooth plate 809 is meshingly connected with the gear six 805; wherein a spring 810 is arranged between the guide cylinder 806 and the limiting plate 808, the spring 810 is sleeved on the circumferential outer wall of the push-pull rod 807, the end of the push-pull rod 807 is connected with a pull frame 811, the side wall of the pull frame 811 is movably penetrated with a movable column 812, one end of the movable column 812 is connected with a push plate 813 and the other end is connected with the end of the transmission tooth plate 909, the push plate 813 is arranged between the pull frame 811 and the movable frame 803.

[0053] In the initial state, the first clamp head 801 and the second clamp head 802 are in the open state, and the spring 810 is in the compressed state; when the transmission tooth plate 909 of the driving assembly 9 slides forward along the slide frame 908, the transmission tooth plate 909 pushes the push plate 813 to move forward through the end of the movable column 812, at this time, the push plate 813 loses the limiting effect on the pull frame 811, the elastic force of the spring 810 is released, driving the pull frame 811, the push-pull rod 807 and the linkage tooth plate 809 to move forward; in this process, the linkage tooth plate 809 can drive the gear six 805 to rotate, and further drive the screw rod 804 to rotate; because the circumferential outer wall of the screw rod 804 is provided with two opposite screw threads and is respectively threadedly connected with the first clamp head 801 and the second clamp head 802, the rotation of the screw rod 804 will drive the first clamp head 801 and the second clamp head 802 to oppositely move in the inner cavity of the movable frame 803, until they accurately clamp the plastic column 11 of the plastic sleeve 10; after clamping is completed, as the driving frame 904 continues to slide forward along the slide rail one 902, the transmission tooth plate 909 moves forward quickly, the push plate 813 is pushed to move forward quickly, the push plate 813 pushes the side wall of the movable frame 803, driving the movable frame 803 to move forward along the guide slide rail five 915, and further driving the clamped plastic sleeve 10 to move forward; at this time, the driving column 708 of the opening and closing positioning assembly 7 enters the curved slot of the guide slot 704, driving the first positioning cover 701 and the second positioning cover 702 to oppositely move to form a separated state, providing space for the forward movement of the core feeding and clamping assembly 8.

[0054] In the process of inserting a chip into molten plastic in a static state, the present invention first inserts the chip into the channel 403 through the chip feeding head 901 of the drive component 9, such as... Figure 16 As shown, during this process, the drive frame 904 slides forward along the slide rail 902. On the one hand, it can drive the opening and closing positioning assembly 7 to move forward synchronously, and cause the first positioning cover 701 and the second positioning cover 702 to move in opposite directions to form a separated state, providing space for the core feeding clamping assembly 8 to move forward. On the other hand, it can drive the transmission gear plate 909 to move forward along the slide 908 at a faster speed through the forward rotation of the gear 906 on the inner wall of the wheel frame 905 on the top of the fixed gear plate 903. The transmission gear plate 909 pushes the push plate 813 forward through the movable column 812 at the end. During this process, the core feeding clamping assembly 8 can clamp the plastic column 11 of the plastic sleeve 10 and drive the clamped plastic sleeve 10 to move forward. The process continues until the first chuck 801, the second chuck 802, and the plastic sleeve 10 enter the inner cavity of the chip feeding head 901 of the drive assembly 9 and stops. At this time, the inner cavity of the chip feeding head 901 is blocked by the first chuck 801 and the second chuck 802 in their combined state, and the plastic sleeve 10, forming a closed state. Furthermore, the closed chip feeding head 901 is located within the chip feeding channel 403, making the chip feeding channel 403 a closed state. In this state, injecting molten plastic into the cavities of the moving mold 3 and the fixed mold 4 in their closed state can prevent the molten plastic from overflowing from the chip feeding channel 403. After the molten plastic fills the cavity and forms a stationary state, the chip feeding head 901 of the drive assembly 9 is then fully inserted into the chip feeding channel 403. Figure 17 As shown, the first chuck 801 and the second chuck 802, which are in a combined state, are fully inserted into the inner cavity of the chip feeding head 901. At the same time, the plastic sleeve 10 enters the cavity and merges into the static molten plastic. At this time, the inner cavity of the chip feeding head 901 is still blocked by the first chuck 801 and the second chuck 802, that is, the chip feeding channel 403 remains closed. This prevents the molten plastic from easily overflowing from the chip feeding channel 403 during the insertion of the plastic sleeve 10 into the static molten plastic. This achieves the effect that the chip feeding channel 403 is closed throughout the entire process and the insertion operation can still be realized. This solves the problem that the molten plastic is easy to overflow during the process of injecting molten plastic into the cavity and during the process of inserting the chip into the static molten plastic.

[0055] The application also realizes the effect that the core feeding and clamping assembly 8 can complete the clamping action on the plastic column 11 of the plastic sleeve 10 during the forward movement of the driving frame 904, and quickly drives the plastic sleeve 10 to move forward to the inner cavity of the core feeding cavity head 901, by designing the driving assembly 9, using the displacement speed caused by the rotation of the gear two 906 superimposed on the sliding speed of the transmission tooth plate 909 on the sliding frame 908, so that the transmission tooth plate 909 moves forward at a faster speed. This design can ensure that the core feeding and clamping assembly 8 has accurately delivered the plastic sleeve 10 to the specified closed position before the core feeding cavity head 901 is initially inserted into the chip feeding channel 403 and the molten plastic is injected into the mold cavity, avoiding the problem of plastic sleeve 10 delivery lag caused by insufficient transmission speed, and further causing the molten plastic to overflow from the chip feeding channel 403 when injected. At the same time, it also saves the precise timing for subsequent insertion of the chip into the static molten plastic, ensuring that the chip can be embedded in time after the molten plastic is completely static, further strengthening the stability of the chip position, and effectively solving the problems of molten plastic overflow and deviation of chip embedding timing.

[0056] As another embodiment of the application, a plurality of semicircular grooves 814 are formed in the inner side wall of the first chuck 801, and a plurality of grooves with the same structure as the semicircular grooves 814 are formed in the inner side wall of the second chuck 802. The semicircular grooves 814 of the first chuck 801 and the semicircular grooves 814 of the second chuck 802 can be combined to form a cylindrical slot structure for clamping and fixing the plastic column 11 of the side wall of the plastic sleeve 10. A plurality of correction plates 815 are integrally formed on the inner side wall of the first chuck 801, and the plurality of correction plates 815 are arranged in a symmetrical structure in the vertical direction on both sides of the slot of the semicircular groove 814. The side wall of the semicircular groove 814 is provided as a beveled structure, and every two vertically symmetrical correction plates 815 are arranged in an open structure. An insertion groove 816 is formed between every two horizontally arranged correction plates 815. The inner side wall of the second chuck 802 is provided with the same structure as the inner side wall of the first chuck 801. The plurality of correction plates 815 of the second chuck 802 are arranged in a staggered manner with the plurality of correction plates 815 of the first chuck 801, and the correction plates 815 of the second chuck 802 are inserted and matched with the insertion grooves 816 of the first chuck 801.

[0057] It is worth mentioning that when the core clamping assembly 8 clamps the plastic column 11 of the plastic sleeve 10, when the screw rod 804 is driven to rotate by the gear six 805, because the screw rod 804 is threadedly connected with the first clamp 801 and the second clamp 802 in opposite directions, it will drive the two clamps to move towards each other in the inner cavity of the movable frame 803. During the movement, the correction plate 815 arranged vertically and symmetrically on the inner side wall of the first clamp 801 in an open shape will first contact the plastic column 11, and the open structure will preliminarily guide and correct the plastic column 11 which may have a positional deviation. At the same time, the inclined surface structure of the side wall of the semicircular groove 814 further assists the plastic column 11 to slide accurately into the groove. As the two clamps continue to approach, the correction plate 815 on the inner side wall of the second clamp 802 has the same structure as that of the first clamp 801, which will form an interlaced fit with the correction plate 815 of the first clamp 801. The correction plate 815 of the second clamp 802 will be inserted into the insertion slot 816 between the horizontal correction plates 815 of the first clamp 801, realizing the close connection of the correction structures of the two clamps and avoiding the deviation of the plastic column 11 caused by the clamping gap. Finally, the semicircular grooves 814 of the first clamp 801 and the second clamp 802 completely merge to form a cylindrical slot structure, firmly clamping and fixing the plastic column 11 on the side wall of the plastic sleeve 10, providing a reliable clamping basis for stably feeding the plastic sleeve 10 and the internal chip main body 2 into the cavity of the fixed mold 4, and ensuring that the chip will not deviate in position due to loose clamping during feeding.
