Description

Technical Field

[0001] The present invention relates to the technical field of intelligent manufacturing equipment industry, and specifically to an automated intelligent injection molding machine and an injection molding method for a feeder card. Background Art

[0002] In modern industrial production, intelligent injection molding machines, with their high efficiency and automation, have become key equipment in the plastics processing industry. Feeder cards, crucial components for securing and supporting feeder lines in fields like power and communications, have a direct impact on the installation and operational stability of related systems. The industry is continuously striving to optimize the structure and operating methods of injection molding machines to improve overall processing efficiency.

[0003] Chinese patent CN118418373B discloses an intelligent injection molding machine, which uses the force of driving the mold to open and close after injection molding as a power source to drive the pickup block to absorb the injection molded product and move the product with it, and then uses another driving force to control the pickup block to move the product to the unloading position for unloading.

[0004] When applied to feeder card production, the aforementioned device is time-consuming to control the pick-up block to attract and move the feeder card after injection molding, due to its delicate structure. Furthermore, due to the smooth surface and small size of the feeder card, the suction-based demolding method is prone to mold failure. If the suction force is insufficient or the product adheres to the mold, it cannot be successfully removed. This not only affects production continuity but also reduces overall processing efficiency, making it difficult to meet the needs of large-scale, high-efficiency feeder card production.

[0052] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0053] Example 1

[0054] See also Figure 1 、 Figure 2 and Figure 3 The present invention provides an automated intelligent injection molding machine, comprising a machine platform 1, a support frame 2, a lifting drive frame 3 and an injection molding device 4, wherein the support frame 2 is fixedly mounted on the machine platform 1, the lifting drive frame 3 is vertically lifted and lowered on the support frame 2, the injection molding device 4 is fixedly mounted on the lifting drive frame 3, a pressing plate 5 is mounted on the injection molding device 4, an upper mold 51 is mounted on the pressing plate 5, a rotating frame 6 is rotatably mounted on the machine platform 1, support platforms 7 are provided on both sides of the rotating frame 6, a lower mold 71 is mounted on the support platform 7, and connecting shafts 72 are fixedly mounted on both ends of the support platform 7, the connecting shafts 72 are rotatably connected to the rotating frame 6, a control mechanism 8 is provided on the rotating frame 6, and the control mechanism 8 includes an anti-rotation limiting mechanism 81, a pushing component 82 and a flipping component 83;

[0055] The anti-rotation limiting mechanism 81 includes a sliding baffle 811, which is slidably mounted on the rotating frame 6, and the upper surface of the sliding baffle 811 is in sliding contact with the lower surface of the support table 7. When the rotating frame 6 rotates so that the support table 7 moves away from the pressing plate 5, the sliding baffle 811 moves toward the rotation axis of the rotating frame 6 to the other side of the connecting shaft 72, thereby allowing the support table 7 to flip toward the outside of the machine platform 1.

[0056] When the support platform 7 is away from the pressing plate 5 , the ejection assembly 82 ejects the formed product from the inside of the lower mold 71 , and the flip assembly 83 pushes the support platform 7 to rotate, so that the upper surface of the support platform 7 flips toward the outside of the machine 1 .

[0057] As can be seen from the above, the automated intelligent injection molding machine realizes efficient connection of product injection molding, demoulding and taking out by setting up a rotating frame 6, a support table 7, a control mechanism 8, an injection molding device 4, an upper mold 51 and a lower mold 71. At the same time, through the setting of the rotating frame 6, the two lower molds 71 ​​are used alternately in the device. When one lower mold 71 is performing injection molding, the other lower mold 71 performs the taking out operation. When the automatic taking out function of the device fails, manual taking out can be performed to ensure the success rate of taking out and avoid obstacles to subsequent repeated processing after the failure of automatic taking out. The anti-rotation limit mechanism 81 limits the flipping of the support table 7 during the injection molding process to ensure the stability of the mold position and the injection molding accuracy. After the injection molding is completed, the anti-rotation limit mechanism 81 releases the restriction on the support table 7, and the ejection component 82 and the flipping component 83 work together to eject and unload the molded product from the lower mold 71. Compared with the traditional injection molding machine, it effectively reduces the time for taking out, avoids the problem of demoulding failure, and significantly improves the overall processing efficiency.

[0058] After the injection molding is completed, the rotating frame 6 rotates to cooperate with the control mechanism 8, which can move the support platform 7 where the molded feeder card is located away from the pressure plate 5, and automatically complete the ejection of the feeder card and the flipping and unloading of the support platform 7. Compared with the traditional adsorption-type pickup, the pickup time is greatly shortened, and the probability of demoulding failure can be reduced. It significantly improves the processing efficiency and production continuity of plastic products such as feeder cards.

[0059] When using the device, the plastic raw material is placed into the injection molding device 4, and the injection molding device 4 is started to preheat it;

[0060] The lifting drive frame 3 is operated to descend on the support frame 2, driving the injection molding device 4 and the upper mold 51 to move downward, so that the upper mold 51 and the lower mold 71 are closed, and the molten plastic is injected into the mold through the injection molding device 4;

[0061] After the injection molding is completed, the lifting drive frame 3 is operated to move upward on the support frame 2 to separate the upper mold 51 and the lower mold 71, and then the rotating frame 6 is controlled to rotate. During the rotation process, the lower mold 71 containing the molded product moves away from the upper mold 51, and the sliding baffle 811 moves to release the restriction on the support platform 7. The ejection assembly 82 ejects the product, and the flip assembly 83 flips the support platform 7 to make the product fall to the outside of the machine 1. At the same time, the lower mold 71 on the other support platform 7 moves to the bottom of the upper mold 51, ready for the next round of injection molding.

[0062] Example 2

[0063] like Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 As shown, the difference between this embodiment and the above embodiment is that the anti-rotation limit mechanism 81 also includes a limit rod 812 and a limit rail 813, the limit rod 812 is fixedly installed on the lower surface of the sliding baffle 811, and the limit rail 813 is fixedly installed on the machine 1, the inner side wall of the limit rail 813 is in sliding contact with the limit rod 812, and the limit rail 813 is set as a heart-shaped rail.

[0064] As can be seen from the above, the limiting track 813 of the heart-shaped track cooperates with the limiting rod 812 to control the moving trajectory of the sliding baffle 811. After the injection molding is completed, the rotating frame 6 rotates, and the limiting rod 812 moves along the limiting track 813 of the heart-shaped track, driving the sliding baffle 811 to move toward the rotation axis of the rotating frame 6 to the other side of the connecting shaft 72, thereby releasing the restriction of the sliding baffle 811 on the support platform 7, so that the support platform 7 can be tilted and flipped to one side.

[0065] The anti-rotation limiting mechanism 81 also includes a reset component 814, which includes a fixed block 8141, a sliding reset spring 8142 and a guide slide rod 8143. The fixed block 8141 is fixedly installed at both ends of the sliding baffle 811, and the two side walls of the rotating frame 6 are fixedly installed with connecting blocks 61. The two ends of the sliding reset spring 8142 are respectively fixedly connected to the fixed block 8141 and the connecting block 61. The guide slide rod 8143 is fixedly installed on the fixed block 8141, and the guide slide rod 8143 is slidably connected to the connecting block 61.

[0066] As can be seen from the above, the reset assembly 814 can ensure that the sliding baffle 811 is automatically reset after the unloading operation is completed. When the rotating frame 6 rotates to make the support platform 7 move to the bottom of the pressure plate 5, under the elastic tension of the sliding reset spring 8142, the fixed block 8141 drives the sliding baffle 811 to move and reset along the guide slide bar 8143, and re-supports and restricts the lower surface of the support platform 7 to prevent the support platform 7 from shaking and flipping during the injection molding process, thereby ensuring the stability of the upper mold 51 and the lower mold 71 during injection molding, and thus ensuring the injection molding accuracy of the product. The guide slide bar 8143 plays a guiding role in the reset process to ensure that the sliding baffle 811 resets smoothly.

[0067] A lap groove 73 is formed at one end of the bottom of the support platform 7 , and lap blocks 62 are fixedly mounted on both ends of the rotating frame 6 , and the lap blocks 62 are adapted to overlap with the lap groove 73 .

[0068] As can be seen from the above, by setting the overlapping groove 73 and the overlapping block 62, due to the adaptive overlapping of the overlapping block 62 and the overlapping groove 73, during the injection molding process, the support platform 7 can be effectively prevented from rotating and shaking in the opposite direction, ensuring that the position of the lower mold 71 is fixed.

[0069] Example 3

[0070] like Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 and Figure 11 As shown, the difference between this embodiment and the above embodiment is that a mounting cavity 74 is provided inside the support platform 7, and an ejection hole 711 is provided at the bottom of the lower mold 71, and the ejection hole 711 is communicated with the cavity of the lower mold 71; the ejection assembly 82 includes a push rod 821, a rotating screw 822, a lifting plate 823, a driven gear 824, an arc-shaped rack 825 and an ejection return spring 826, the push rod 821 slides through the inner top wall of the mounting cavity 74 and extends to the top of the support platform 7, and the upper end of the push rod 821 extends to the inside of the ejection hole 711, the rotating screw 822 is rotatably installed at the bottom of the support platform 7, and its The upper end passes through the lower surface of the support platform 7 and extends to the interior of the mounting cavity 74. The lifting plate 823 is slidably installed in the interior of the mounting cavity 74, and the lifting plate 823 is threadedly connected to the rotating screw 822. The push rod 821 is fixedly installed on the lifting plate 823. The driven gear 824 is arranged below the support platform 7, and the driven gear 824 is fixedly installed on the rotating screw 822. The arc-shaped rack 825 is fixedly installed on the machine table 1, and the arc-shaped rack 825 is adapted to mesh with the driven gear 824. The two ends of the push-up reset spring 826 are respectively fixedly connected to the inner bottom wall of the mounting cavity 74 and the lower surface of the lifting plate 823.

[0071] As can be seen from the above, when the rotating frame 6 rotates and the support platform 7 with the molded product is away from the pressing plate 5, the driven gear 824 approaches the arc rack 825 and meshes with the arc rack 825 to rotate, driving the rotating screw 822 to rotate. Since the lifting plate 823 is slidably installed in the installation cavity 74 and is threadedly connected to the rotating screw 822, the rotation of the rotating screw 822 will cause the lifting plate 823 to rise, thereby pushing the push rod 821 fixed on the lifting plate 823 to pass through the ejection hole 711, ejecting the molded product in the cavity of the lower mold 71, and pushing the return spring 826 After the driven gear 824 is disengaged from the arc-shaped rack 825, a reset force is provided, so that the lifting plate 823 and the push rod 821 automatically fall back after completing the ejection action, preparing for the next ejection; at the same time, in this embodiment, the lower end of the push rod 821 extends from the lower surface of the lifting plate 823 and cooperates with the ejection reset spring 826, so that after the reset is completed, the upper end of the push rod 821 is flush with the upper surface of the ejection hole 711, and the ejection reset spring 826 will not be excessively squeezed by the internal pressure during the injection molding process, thereby avoiding the appearance of excess cylindrical blocks on the molded feeder card.

[0072] The flip assembly 83 includes a lower rotating seat 831, an upper rotating seat 832 and an elastic rotating rod 833. The lower rotating seat 831 is fixedly installed on the side of the sliding baffle 811, and the upper rotating seat 832 is fixedly installed on the bottom of the support platform 7. The two ends of the elastic rotating rod 833 are respectively rotatably connected to the lower rotating seat 831 and the upper rotating seat 832.

[0073] It can be seen from the above that when the sliding baffle 811 moves toward the rotation axis of the rotating frame 6, before the sliding baffle 811 moves to the other side of the connecting shaft 72, the sliding baffle 811 can prevent the support platform 7 from rotating. By setting the elastic rotating rod 833, the elastic rotating rod 833 is compressed and deformed at this stage. After the sliding baffle 811 moves to the other side of the connecting shaft 72, the elastic force accumulated in the elastic rotating rod 833 is released, causing the support platform 7 to rotate faster, thereby causing the feeder card that is still attached to the surface of the lower mold 71 after the ejection component 82 is ejected to bounce up, thereby avoiding the friction between the feeder card and the lower mold 71 from hindering the feeder card from falling.

[0074] A guide rod 21 and a lifting cylinder 22 are fixedly mounted on the support frame 2 . The lifting drive frame 3 is slidably mounted on the guide rod 21 . The driving end of the lifting cylinder 22 is fixedly connected to the lifting drive frame 3 .

[0075] As can be seen from the above, the cooperation between the guide rod 21 and the lifting cylinder 22 realizes the stable vertical lifting of the lifting drive frame 3. The driving end of the lifting cylinder 22 pushes the lifting drive frame 3 to move up and down on the guide rod 21, thereby driving the injection molding equipment 4, the pressure plate 5 and the upper mold 51 to rise and fall synchronously.

[0076] Example 4

[0077] like Figure 5 、 Figure 10 、 Figure 12 and Figure 13 As shown, the difference between this embodiment and the above embodiment is that the injection molding equipment 4 includes a barrel 41, a loading bin 42, a pushing mechanism 43 and an injection head 44. The injection head 44 is fixedly mounted on the output end of the barrel 41. The barrel 41, the loading bin 42 and the pushing mechanism 43 are all fixedly mounted on the lifting drive frame 3. The loading bin 42 is used to transport materials into the barrel 41, and the pushing mechanism 43 is used to stir and mix the materials and make the materials ejected from the injection head 44.

[0078] As can be seen from the above, through the arrangement of the feeding bin 42, the barrel 41, the pushing mechanism 43 and the injection head 44, the complete process of conveying, melting, stirring and injection molding of the plastic raw materials is realized. The feeding bin 42 conveys the plastic raw materials into the barrel 41, the barrel 41 heats and melts the raw materials, and the pushing mechanism 43 stirs and mixes the molten material in the barrel 41 to ensure the uniformity and plasticization quality of the material, and then the evenly mixed molten material is injected into the mold cavity through the injection head 44.

[0079] A vertical guide rod 52 is fixedly installed on the pressure plate 5, and the vertical guide rod 52 is slidingly connected to the support frame 2, and a stopper 53 is fixedly installed on the vertical guide rod 52. A sleeve 411 is fixedly installed on the outer wall of the barrel 41, and the stopper 53 is slidingly connected to the inner wall of the sleeve 411, and the diameter of the stopper 53 is larger than the diameter of the bottom opening of the sleeve 411. A support spring 54 is fixedly installed between the upper end of the vertical guide rod 52 and the inner top of the sleeve 411.

[0080] As can be seen from the above, when the lifting drive frame 3 drives the injection molding equipment 4 and the pressure plate 5 to rise and fall, the vertical guide rod 52 slides on the support frame 2 to play a guiding role, ensuring the accuracy of the lifting of the pressure plate 5 and the upper mold 51. Through the cooperation of the stopper 53 and the sleeve 411, when the barrel 41 rises, the sleeve 411 pulls up the stopper 53 to rise, avoiding the support spring 54 from continuously pulling the pressure plate 5. In this embodiment, when the barrel 41 rises, the weight of the pressure plate 5 and the upper mold 51 causes the support spring 54 to be stretched under force. When the bottom wall contacts the stop block 53, the support spring 54 will no longer be subjected to a greater tensile force. Therefore, during the mold opening process, the lifting cylinder 22 pushes the barrel 41 to rise. After the barrel 41 rises a certain distance, the upper mold 51 rises accordingly under the pull of the sleeve 411. That is, after the mold is opened, there is a gap between the injection head 44 and the injection port of the upper mold 51, and the two will not be close to each other for a long time. In addition, during the mold closing process, the support spring 54 can provide a buffering force to avoid wear or deformation due to rigid collision when the upper mold 51 and the lower mold 71 are closed.

[0081] The support frame 2 includes three vertical rods 23 and a top plate 24 distributed in a circular array with the central axis of the barrel 41 as the axis. The top plate 24 is fixedly connected to the machine table 1 through the vertical rods 23. A drive motor 9 is fixedly installed on the machine table 1. A drive gear 91 is fixedly installed on the driving end of the drive motor 9. A driven gear ring 92 is fixedly installed on the lower surface of the rotating frame 6. The driven gear ring 92 and the drive gear 91 are meshed and connected. The rotating frame 6 is rotatably installed on one of the vertical rods 23, and the driven gear ring 92 is sleeved on the outside of the vertical rod 23; the pressure plate 5 is slidably installed on the vertical rod 23.

[0082] As can be seen from the above, after the driving motor 9 is started, the driving gear 91 drives the driven gear ring 92 to rotate, thereby driving the rotating frame 6 to rotate, and by setting the pressing plate 5 and the vertical rod 23 in sliding connection, the upper mold 51 is raised.

[0083] Stability of movement

[0084] Example 5

[0085] See also Figure 1 - Figure 13 The present invention also discloses an injection molding method for a feeder card, which comprises the following specific steps:

[0086] Put the plastic raw material into the injection molding device 4, and start the injection molding device 4 to preheat the plastic raw material;

[0087] The lifting drive frame 3 is operated to descend on the support frame 2, driving the injection molding device 4 and the upper mold 51 to move downward, so that the upper mold 51 and the lower mold 71 are closed, and the molten plastic is injected into the mold through the injection molding device 4;

[0088] After the injection molding is completed, the lifting drive frame 3 is operated to move upward on the support frame 2 to separate the upper mold 51 and the lower mold 71, and then the rotating frame 6 is controlled to rotate. During the rotation process, the lower mold 71 containing the molded product moves away from the upper mold 51, and the sliding baffle 811 moves to release the restriction on the support platform 7. The ejection assembly 82 ejects the product, and the flip assembly 83 flips the support platform 7 to make the product fall to the outside of the machine 1. At the same time, the lower mold 71 on the other support platform 7 moves to the bottom of the upper mold 51, ready for the next round of injection molding.

[0089] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
