Abstract

This invention relates to the field of plastic bottle manufacturing technology, specifically to a plastic bottle with a built-in identification chip, a manufacturing apparatus, and a manufacturing method. The plastic bottle includes a bottle body and a cap. The cap includes a first injection molding block and a second injection molding block. The first injection molding block has a threaded portion, a removable portion with an easy-tear edge, and a top cover portion. The top cover portion has a mounting groove for placing the chip. The second injection molding block seals the mounting groove, thereby securely encapsulating the chip. The manufacturing apparatus includes mold A and mold B arranged opposite each other. Through the coordinated action of the first pushing portion, the second pushing portion, and the adjusting component in the molds, after the bottle cap body with the mounting groove is formed by the first mold closing injection molding, the chip is placed in. During the second mold closing injection molding, the mounting groove is isolated by the blocking portion, and the second injection molding block is formed. This achieves non-adhesive encapsulation of the chip and the plastic bottle cap, thereby facilitating the effective separation of the plastic bottle cap and the chip, and reducing the difficulty and cost of recycling the plastic bottle cap.

Description

Technical Field

[0001] This invention relates to the field of plastic bottle production technology, specifically to a plastic bottle with a built-in identification chip, a production device, and a production method thereof. Background Technology

[0002] Manufacturers combat counterfeit and substandard products by adding QR codes and barcodes to medicine bottles and outer packaging, but these markings are easily erased or scratched off.

[0003] Chinese patent application number CN202010501287.1 discloses an anti-counterfeiting bottle cap and a bottle, belonging to the field of anti-counterfeiting technology. The anti-counterfeiting bottle cap includes: an outer cap, including an outer cap plate, the inner side of which is provided with a button protrusion; an inner cap, which is fitted inside the outer cap, the inner cap including an inner cap plate and an inner cap side plate, the inner cap plate and the inner cap side plate forming a first receiving cavity, the opening of the first receiving cavity facing the outer cap plate; and a communication chip located in the first receiving cavity, the communication chip having a trigger switch; when the outer cap rotates in a first clockwise direction, the button protrusion can rotate to above the trigger switch and squeeze the trigger switch, so that the communication chip is turned on.

[0004] Although the relevant patented technologies can improve the recognition effect of products by installing communication chips, there are still some technical problems that need to be solved in practical applications.

[0005] Specifically, in the current field of anti-counterfeiting technology for pharmaceutical and health product packaging, especially in the design of anti-counterfeiting bottle caps based on communication chips, two main types of key technical problems restrict their large-scale application and sustainable development. First, at the structural and manufacturing process level, most existing technologies employ a scheme where multiple discrete components, such as outer and inner caps, are assembled to fix the communication chip. This multi-component design not only increases mold development and parts production costs but also introduces additional assembly processes such as chip alignment and fixing, leading to a more complex production process and reduced efficiency, making it difficult to effectively control overall manufacturing costs. Second, at the end-of-life recycling stage, because the communication chip (often containing non-plastic materials such as metal antennas and silicon-based chips) is integrated with the plastic bottle cap through injection molding or tight assembly, forming a complex composite material structure, it is difficult to effectively separate it using conventional physical sorting methods after disposal. This not only increases the difficulty and cost of recycling the plastic bottle cap but may also negatively impact the purity and performance of the recycled plastic. Summary of the Invention

[0006] The purpose of this invention is to provide a plastic bottle with a built-in identification chip, a production device and a production method thereof, in order to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: A plastic bottle with a built-in identification chip includes a bottle body and a bottle cap, wherein the bottle cap includes a first injection molding block and a second injection molding block; The first injection molding block includes a threaded portion, a disassembly portion is provided at the top of the threaded portion, a top cover portion is provided above the disassembly portion, and a chip placement groove is provided on the top cover portion; The second injection block is located on the side of the placement groove to seal the placement groove.

[0009] The present invention provides a production apparatus for plastic bottles with a built-in identification chip, comprising an A mold and a B mold arranged opposite to each other, wherein the A mold includes A1, A2, A3 and A4 templates installed in sequence; The A1 template is provided with arrayed main body forming grooves, and a first pushing part is provided on the outside of the main body forming grooves; The A2 template has an array of axially sliding second pushing parts, and the second pushing parts are provided with flow holes. The B mold is provided with a demolding component, and the demolding component is provided with an adjusting component. When the A mold and the B mold are closed, the demolding component and the main molding groove form the molding chamber of the bottle cap. When the bottle cap is injection molded, both the first pushing part and the second pushing part are in the second position, and the second pushing part abuts against the first pushing part to form a chip placement groove; During the secondary injection molding of the bottle cap, both the first and second pushing parts are in the first position, with the end of the second pushing part overlapping the outer peripheral wall of the bottle cap, and the injection liquid enters the molding chamber through the flow hole.

[0010] Preferably, the A2 template is provided with an injection hole that communicates with the molding chamber, and the A3 template is provided on the outside of the A2 template. The A3 template is provided with a flow channel and an injection channel that communicate with the flow hole and the injection hole, respectively.

[0011] Preferably, an array of first pushing members are provided between the A3 template and the A4 template. The first pushing members are used to push the A1, A2, and A3 templates to separate from the A4 template. The A4 template is provided with an injection head opposite to the flow channel and the injection channel.

[0012] Preferably, the B mold includes B1, B2, and B3 templates installed sequentially; The B1 template is provided with an array of pushers, and a second pusher is provided between the B1 template and the B2 template. The second pusher is used to push the B1 template and the B2 template to separate. An installation space is provided between the B2 template and the B3 template, and the demolding component is located inside the installation space.

[0013] Preferably, the demolding component includes mating blocks arranged in an array inside mold B, and the mating blocks are provided with adjusting components inside; The outer side of the mating block is provided with a rotating unit, which is rotatably connected to mold B. The end of the rotating unit facing the main forming groove is provided with an annular thread head.

[0014] Preferably, the adjusting member includes protrusions arrayed on the mating block, and a blocking portion with the same width as the first pushing portion is provided on the outer side of the protrusions, and a positioning portion is provided in the area enclosed by the protrusions and the blocking portion; The protrusion, blocking part and positioning part can slide axially on the mating block through their respective driving elements; When the protrusion, blocking part, and positioning part are in the first position, the end of the mating block is flat; when the protrusion, blocking part, and positioning part are in the second position, all three abut against the first pushing part; when the blocking part is in the third position, the blocking part seals the mounting groove.

[0015] This invention provides a method for manufacturing plastic bottles with built-in identification chips, the specific steps of which are as follows: S100, One-time mold closing: Using an external drive device, mold A and mold B are forced to close, so that the demolding part and the main body forming groove together form the forming chamber of the bottle cap; in this state, the first pushing part is in the second position, and the second pushing part and the adjusting part are both in contact with the first pushing part; S200, One-time injection molding: Melt is injected into the molding chamber through the injection head and the injection channel, thereby forming a first injection block in the molding chamber; wherein, the disassembly part of the first injection block is composed of a protrusion, a positioning part, a blocking part and a first pushing part; S300, One-time mold parting: First, control the second pushing part to return to the first position, and at the same time, make the first pushing part to the third position. Then, control mold A and mold B to perform mold parting operation. S400, Chip Placement: With the help of an external device, the identification chip is precisely placed at the location of the first push unit; S500, Secondary mold closing: Drive mold A and mold B to close again to ensure that the placement groove corresponds to the position of the first pusher; then, use the first pusher to push the chip into the placement groove and fix the chip by the positioning part; after this operation is completed, the first pusher returns to the first position, and the blocking part extends to the third position to seal the placement groove. S600, Secondary Injection: The injection head injects melt again into the molding cavity through the flow channel, thereby forming a second injection block in the molding cavity; due to the isolation effect of the blocking part, the melt will not flow into the interior of the placement tank; S700, Secondary Mold Separation: Controls the separation of mold A and mold B, and the demolding component demolds the formed bottle cap.

[0016] Preferably, when the first pushing part retracts to the third position, there is a placement area for placing the chip between the first pushing part and the A1 template.

[0017] The technical effects and advantages of this invention are as follows: 1. In this invention, the chip is placed in a pre-reserved slot inside the bottle cap using a non-adhesive method and sealed by a second injection molding block, ensuring that the chip is not bonded to the bottle cap body, thus facilitating subsequent chip recycling. When the chip needs to be recycled, simply tear open the disassembly part of the bottle cap along the specially designed easy-tear edge to remove the chip completely, avoiding the separation difficulties caused by traditional integrated injection molding structures, and promoting the recycling and environmentally friendly disposal of electronic components.

[0018] 2. The present invention provides a first pushing member. During the first mold closing, the first pushing member in the second position serves as an intermediate carrier to form a placement groove during the molding of the first injection molded part. During the first mold opening, the first pushing member in the third position forms a placement area for placing the chip between it and the sliding groove, which facilitates the placement of the chip. During the second mold closing, the chip is pushed into the placement groove by the extension action of the first pushing member. Through the cooperation of the positioning part and the blocking part, the chip and the bottle cap are non-adhesively installed. Attached Figure Description

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0022] Example 1 Reference Figures 1 to 2 As shown, the present invention provides a plastic bottle with a built-in identity recognition chip, including a bottle body and a bottle cap 1. The bottle cap 1 includes a first injection molding block 101 and a second injection molding block 102. The first injection molding block 101 and the second injection molding block 102 can be injection molded using the same or different melts.

[0023] The first injection molding block 101 includes a threaded portion 1011, a disassembly portion 1012 is provided at the top of the threaded portion 1011, a top cover portion 1013 is provided above the disassembly portion 1012, and a mounting groove 1014 for mounting the chip 6 is provided on the top cover portion 1013; the second injection molding block 102 is located on the side of the mounting groove 1014 to seal the mounting groove 1014.

[0024] After the first injection molding block 101 is formed, the chip 6 is placed in the placement groove 1014. Then, the side area of ​​the placement groove 1014 is sealed by the injection molding machine to confine the chip 6 inside the placement groove 1014. It should be noted that the chip 6 is only located inside the placement groove 1014, and is not adhered to the first injection molding block 101 or the second injection molding block 102.

[0025] Reference Figures 1 to 2 As shown, the disassembly part 1012 includes a partition, on which there is a blocking hole 10123 of the same width as the mounting groove 1014. The outer side of the blocking hole 10123 is provided with an array of recessed holes 10121. The blocking hole 10123 and the recessed holes 10121 together form an easy-tear edge on the partition. The area enclosed by the blocking hole 10123 and the recessed holes 10121 is provided with a positioning hole 10122 for positioning the chip 6.

[0026] When chip 6 needs to be recycled, it can be removed by simply tearing the easy-tear edge formed by the blocking hole 10123 and the concave hole 10121. Since chip 6 is placed in the placement slot 1014 instead of being stuck to the bottle cap 1, the inconvenience of recycling chip 6 is avoided.

[0027] Example 2 Existing technologies for producing plastic bottle caps with built-in identification chips mostly employ a solution of assembling multiple discrete components, such as an outer cap and an inner cap, to secure the communication chip. This multi-component design not only increases mold development and parts production costs but also introduces additional assembly processes such as chip alignment and fixing, leading to a more complex production process, reduced efficiency, and difficulty in effectively controlling overall manufacturing costs. Secondly, regarding recycling at the end of the product's lifecycle, because the communication chip and the plastic bottle cap are integrated through injection molding or tight assembly, forming a complex composite material structure, it is difficult to effectively separate them using conventional physical sorting methods after disposal. Therefore, this invention provides a production apparatus for manufacturing plastic bottles with built-in identification chips.

[0028] Reference Figures 1 to 10 As shown, the present invention provides a production apparatus for producing plastic bottles with built-in identification chip 6, including an A mold 2 and a B mold 3 arranged opposite to each other. The A mold 2 includes an A1 template 201, an A2 template 202, an A3 template 203, and an A4 template 204 installed in sequence.

[0029] The A1 template 201 is provided with arrayed main body forming grooves 205. The outer side of the main body forming groove 205 is provided with a sliding groove. The inner side of the sliding groove is provided with a first pushing part 206, which includes a movable plate and an elastic element.

[0030] The first pushing part 206 extends into the main body forming groove 205 at an arc-shaped end, which is the same as the arc of the outer peripheral wall of the bottle cap 1. The outer side of the A1 template 201 is provided with evenly distributed A1 air channels, which are connected to the sliding groove. By precisely controlling the flow rate of air extraction and delivery into the sliding groove from the external air supply device, the movement distance of the movable plate can be controlled. Besides using gas to drive the first pushing part 206, hydraulic or other methods can also be used to drive the first pushing part 206 to move within the sliding groove. Controlling the movement of the movable plate through external equipment is existing technology and will not be elaborated further here.

[0031] The A2 template 202 has an array of movable chambers opposite to the main molding groove 205. Each movable chamber has a second pushing part 207, which includes a movable block and a spring. The movable block has a flow hole 208 through which the melt enters the molding chamber.

[0032] The outer side of the A2 template 202 is provided with evenly distributed A2 air channels, which are connected to the movable chamber. By precisely controlling the flow rate of air extraction and delivery into the movable chamber from the external air supply device, the movement distance of the movable block can be controlled. In addition to the gas-driven movement of the second pusher 207, hydraulic or other methods can also be used to drive the second pusher 207 to move within the movable chamber. Controlling the movement of the movable block through external devices is prior art and will not be elaborated further here.

[0033] Reference Figure 4 As shown, template A2 202 is provided with a liquid injection hole 209 that communicates with the molding chamber. Template A3 203 is provided on the outside of template A2 202. Template A3 203 is provided with a flow channel 210 and a liquid injection channel 211 that communicate with the flow hole 208 and the liquid injection hole 209, respectively.

[0034] Reference Figure 4 As shown, an array of first pushers 212 are provided between template A3 203 and template A4 204. The first pushers 212 are used to push template A1 201, template A2 202, template A3 203 and template A4 204 to separate. Template A4 204 is provided with an injection head opposite to the flow channel 210 and the liquid injection channel 211.

[0035] The first pusher 212 pushes the A1 template 201, A2 template 202, A3 template 203 and A4 template 204 to separate them, thereby exposing the flow channel 210 and the liquid injection channel 211 on the A3 template 203, which makes it easier to clean up the waste generated during the injection molding of the bottle cap 1.

[0036] Reference Figures 5 to 6 As shown, mold B3 includes B1 template 301, B2 template 302, and B3 template 303 installed sequentially.

[0037] The B1 template 301 is provided with an array of pushers 304, and a second pusher 305 is provided between the B1 template 301 and the B2 template 302. The second pusher 305 is used to push the B1 template 301 and the B2 template 302 to separate. The second pusher 305 pushes the B1 template 301 and the B2 template 302 to separate them, so that the pusher 304 on the B1 template 301 pushes the formed bottle cap 1 off.

[0038] An installation space is provided between template B2 302 and template B3 303. A demolding component 4 is provided inside the installation space to form the thread of the threaded part 1011.

[0039] Reference Figures 5 to 8 As shown, the demolding component 4 includes mating blocks 403 arranged in an array inside the mold B 3, and an adjusting component 5 is provided inside the mating block 403; the adjusting component 5 is used to form an easy-tear edge and to seal the already formed placement groove 1014.

[0040] A rotating unit 401 is provided on the outer side of the mating block 403. The rotating unit 401 is rotatably connected to the B mold 3. The end of the rotating unit 401 facing the main body forming groove 205 is provided with an annular thread head 402.

[0041] Reference Figures 5 to 7 As shown, the rotating unit 401 includes an array of driven gears, which are rotatably connected to mold B 3. The driven gears are driven by a driving wheel located in the installation space, and a drive motor is located outside the driving wheel. A connecting cylinder is located in the middle of the driven gear, and the end of the connecting cylinder away from the driven gear is connected to an annular threaded head 402. A mating block 403 is located inside the connecting cylinder and is fixedly connected to mold B 3.

[0042] Reference Figures 7 to 8 As shown, the adjusting member 5 includes protrusions 501 arrayed on the mating block 403, and a blocking part 503 of the same width as the first pushing part 206 is provided on the outer side of the protrusions 501. A positioning part 502 is provided in the area enclosed by the protrusions 501 and the blocking part 503. The protrusion 501, the blocking part 503 and the positioning part 502 correspond to the recess 10121, the blocking hole 10123 and the positioning hole 10122 of the disassembly part 1012, respectively.

[0043] The protrusion 501, the blocking part 503 and the positioning part 502 can slide axially on the mating block 403 through their respective driving elements; Reference Figure 6 As shown, template 303 B3 is provided with mating holes corresponding to the protrusion 501, the blocking part 503 and the positioning part 502 respectively. External driving elements can drive the corresponding parts to slide axially on the mating block 403 through the corresponding mating holes. Setting driving elements to drive the parts set in the mating block 403 to move is the prior art, and will not be described in detail here.

[0044] It should be noted that in this embodiment, when the bottle cap 1 is injection molded for the first time, both the first pushing part 206 and the second pushing part 207 are in the second position, and the second pushing part 207 abuts against the first pushing part 206 to form the placement groove 1014 of the chip 6; when the bottle cap 1 is injection molded for the second time, both the first pushing part 206 and the second pushing part 207 are in the first position, and the end of the second pushing part 207 coincides with the outer peripheral wall of the bottle cap 1, and the injection liquid enters the molding chamber through the flow hole 208.

[0045] It should be noted that when the protrusion 501, the blocking part 503 and the positioning part 502 are in the first position, the end of the mating block 403 is flat; when the protrusion 501, the blocking part 503 and the positioning part 502 are in the second position, all three abut against the first pushing part 206; when the blocking part 503 is in the third position, the blocking part 503 blocks the mounting groove 1014.

[0046] In the initial state, the first pushing part 206 is in the first position, that is, the end of the first pushing part 206 coincides with the main body forming groove 205; the second pushing part 207 is in the first position, and its end away from the first pushing part 206 is in contact with the liquid outlet end of the flow channel; the adjusting parts 5 are all in the first position, that is, the ends of the protrusion 501, the positioning part 502, and the blocking part 503 near the first pushing part 206 are all flush with the end of the mating block 403, as detailed in the reference. Figure 9 As shown.

[0047] In use, the external drive device is first used to cause mold A 2 and mold B 3 to close, so that the demolding part 4 and the main molding groove 205 together form the molding chamber of the bottle cap 1.

[0048] After the mold is closed, the first pushing part 206 is first moved to the second position by an external air supply device, that is, the end of the first pushing part 206 extends into the molding cavity, so as to form the placement groove 1014 on the first injection block 101 in the subsequent injection molding process. After the first pushing part 206 moves to the second position, the air supply device connected to the movable cavity is activated to drive the second pushing part 207 to move to the second position, that is, the end of the second pushing part 207 near the first pushing part 206 abuts against the outer surface of the first pushing part 206, so as to form a secondary injection hole connected to the placement groove 1014 in the first injection molding. As the second pushing part 207 moves to the second position, the external driving element drives the adjusting part 5 to move to the second position through the corresponding mating hole. That is, the end of the protrusion 501, the positioning part 502 and the blocking part 503 near the first pushing part 206 abuts against the outer surface of the second pushing part 207 so as to form the recess 10121, the positioning hole 10122 and the blocking hole 10123 on the disassembly part 1012 during one injection molding.

[0049] It is important to note that although the first pushing part 206, the second pushing part 207, and the adjusting part 5 all move to their respective second positions during a single injection molding process, in actual application, they move in a specific order. Specifically, the first pushing part 206 moves to its second position first, followed by the second pushing parts 207 and the adjusting part 5 located on either side of the first pushing part 206. This avoids the first pushing part 206 from "collision" with the mold due to a disordered moving sequence.

[0050] After the positions of the first pushing part 206, the second pushing part 207, and the adjusting member 5 are adjusted, the injection head is controlled to inject melt into the injection channel 211. The melt enters the interior of the molding cavity through the injection channel 211 and the injection hole 209, and forms the first injection block 101 in the molding cavity. Specifically, after the melt enters the molding cavity through the injection hole 209, it gradually fills the molding cavity. However, due to the influence of the positions of the first pushing part 206, the second pushing part 207, and the adjusting member 5, the melt cannot fill the positions of the three parts. As a result, during one injection, the position of the first pushing part 206 will form a placement groove 1014, the position of the second pushing part 207 will form a secondary injection hole, and the position of the adjusting member 5 will form a disassembly part 1012.

[0051] It should be noted that in this embodiment, the width of the first pushing part 206 and the blocking part 503 is smaller than the diameter of the main body molding groove 205, so that after the melt enters the molding chamber, the first pushing part 206 and the blocking part 503 will not completely block the flow of the melt in the molding chamber.

[0052] It should be noted that in this embodiment, mold A 2 is equipped with a cooling device (not shown in the figure) to cool and shape the melt inside the molding cavity. Setting a cooling device to accelerate the cooling and shaping of the injection molded part is prior art and will not be described in detail here.

[0053] The complete molding of the melt inside the molding chamber (first injection block 101) is determined by setting a time or other detection method. After the first injection block 101 is molded, the second pushing part 207 is driven back to the first position by the operation of the air supply device connected to the movable chamber, that is, the end of the second pushing part 207 away from the first pushing part 206 abuts against the flow hole 208. Then, the first pushing part 206 is driven to the third position by the operation of the air supply device connected to the sliding groove, that is, the end of the first pushing part 206 retracts into the sliding groove, and the first pushing part 206 and the sliding groove form the placement area for placing the chip 6.

[0054] It should be noted that in this embodiment, after the first injection block 101 is formed, the adjusting component 5 can also be driven to return to the initial state by an external driving element.

[0055] After both the first pushing part 206 and the second pushing part 207 disengage from the first injection block 101, the mold A 2 and the mold B 3 are controlled to perform a mold separation operation. At this time, due to the restriction of the threaded part 1011 on the first injection block 101, the first injection block 101 will remain on the demolding part 4 of the mold B 3. After completing one mold separation, the identification chip 6 is accurately placed in the placement area of ​​the chip 6 formed by the first pushing part 206 and the sliding groove using an external device such as a robotic arm.

[0056] It should be noted that in this embodiment, the height of the placement area is greater than or equal to the height of the chip 6, and the thickness of the sliding groove is adapted to the thickness of the chip 6 so that the first pushing part 206 pushes the chip 6 into the placement groove 1014.

[0057] After the chip 6 is placed, the mold A 2 and mold B 3 are closed again (secondary mold closing). After the secondary mold closing is completed, the pusher is first controlled to push the chip 6 in the placement area into the placement groove 1014. Then, the external drive element connected to the positioning part 502 is controlled to move so that the positioning part 502 extends further towards the mold A 2. That is, the end of the positioning part 502 extends into the placement groove 1014 and abuts against the chip 6. The chip 6 is fixed by the squeezing of the positioning part 502.

[0058] After chip 6 is fixed, the first pushing part 206 returns to the first position, that is, the arc-shaped end of the first pushing part 206 coincides with the outer diameter of the main body molding groove 205. Then, the external driving element connected to the blocking part 503 is controlled to operate, so that the blocking part 503 extends into the interior of the placement groove 1014, thereby sealing the placement groove 1014.

[0059] The injection head injects molten material into the flow channel 210. The molten material enters the molding cavity through the flow channel 210 and the flow hole 208, and then enters the placement groove 1014 through the secondary injection hole on the first injection body. Since the placement groove 1014 is blocked by the blocking part 503, the molten material can only enter the side area of ​​the placement groove 1014 and solidify in the side area to form the second injection block 102. This allows the second injection block 102 to block the placement groove 1014, thereby achieving non-adhesive mounting of the chip 6 inside the placement groove 1014.

[0060] After the second injection molding block 102 is formed, mold A 2 and mold B 3 are separated (secondary mold separation). After the mold separation is completed, the bottle cap 1 is demolded, and the waste generated from injection molding is processed. Specifically: For mold A 2: After mold A 2 and mold B 3 complete the second mold separation, control the first pusher 212 to extend so as to realize the separation operation of mold A3 template 203 and mold A4 template 204, so that the waste material between mold A3 template 203 and mold A4 template 204 (injection waste in flow channel 210 and injection channel 211) can be discharged so that the staff can clean it.

[0061] For mold B 3: After molds A 2 and B 3 complete the secondary mold separation, the drive rotation unit 401 and the second pusher 305 move synchronously to achieve the demolding of the bottle cap 1. Specifically: the drive rotation unit 401 rotates to drive the annular threaded head 402 to rotate synchronously, so as to unlock the threaded part 1011 from the annular threaded head 402; the drive second pusher 305 is used to separate the B1 template 301 and the B2 template 302. It is worth noting that the rotation speed of the rotation unit 401 needs to establish a communication connection with the elongation rate of the second pusher 305 to avoid damage to the threaded part 1011 caused by the difference in their operating speeds. The communication connection is existing technology and will not be elaborated further here.

[0062] It should be noted that a micro-protrusion can be provided on the inner ring of the pusher 304 facing the A mold 2. After the A mold 2 and the B mold 3 are closed, the micro-protrusion is located in the molding cavity, thereby forming a stop part in the first injection block 101, thus avoiding the problem of the bottle cap 1 rotating synchronously during the rotation of the annular thread head 402.

[0063] After demolding, all parts return to their initial state, ready for the next injection molding operation.

[0064] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
