Description

Technical Field

[0001] This invention relates to an injection molding system structure, and more particularly to a four-sided rotating dual-color intelligent mold molding system and method. Background Technology

[0002] With the continuous development of plastic injection molding technology, mold design is also gradually moving towards high efficiency, intelligence, and precision. Traditional injection molds often rely on sequential actions at a single station, which limits production efficiency and molding quality. This is especially true in the molding process of two-color or multi-component materials. For example, in the production of a two-color anti-counterfeiting bottle cap using two immiscible plastic raw materials, PP and HDPE, both materials are centrally injected. PP is a transparent card, allowing subsequent processes to add image recognition technology inside the product through the transparent material, preventing the contents from contacting the image, avoiding contamination from surface laser coding, ensuring food safety, upgrading product traceability, and raising the product's technological barriers. In contrast, traditional production uses a snap-fit ​​structure to achieve the original two-piece assembly method, which suffers from long operation cycles, low efficiency, and unstable product quality.

[0003] To overcome these problems, the market demand for intelligent molding systems with multi-station synchronous operation is increasing. However, existing technologies have not yet realized a system that can synchronously superimpose molding requirements from different stations. In particular, there are still many technical bottlenecks in precision molding with multiple cavities and multiple stations. Summary of the Invention

[0004] The purpose of this invention is to provide a four-sided rotating dual-color intelligent mold forming system and method, which has higher production efficiency and more precise molding quality compared with traditional molds, and can realize synchronous superposition of actions between multiple workstations to adapt to more complex injection molding needs.

[0005] This invention provides the following technical solution:

[0006] A four-sided rotating dual-color intelligent mold forming system and method includes a central cubic rotating center body and four sets of tooling evenly distributed around the periphery of the cubic rotating center body. The four sets of tooling are driven by the cubic rotating center body to rotate synchronously in 90° increments, enabling alternating operations at the first-color injection station, cooling station, second-color injection station, and ejection station. At the first-color and second-color injection stations, a motorized injection mold and a stationary injection mold are arranged. The motorized injection mold and the cubic rotating center body move linearly under the drive of their respective linear reciprocating drive components. After the cubic rotating center body completes its rotation, the motorized injection mold and the stationary injection mold are aligned with the two sets of tooling. The alignment of the motorized injection mold with the tooling forms the mold cavity for the first-color injection of the product, and the alignment of the stationary injection mold with the tooling forms the mold cavity for the second-color injection of the product.

[0007] In the production of two-color anti-counterfeiting packaging bottle caps, the first color is transparent PP material, and the second color is HDPE material. Four sets of tooling rotate sequentially through four stations: the first-color injection station, the cooling station, the second-color injection station, and the ejection station. At the first-color injection station, after the injection molding machine aligns with the tooling, the injection plastic enters the injection cavity formed by the injection molding machine and the tooling to injection mold the PP transparent card. Then, the cubic rotation center continues to rotate through the tooling, driving the injection-molded PP transparent card to the cooling station. The PP transparent card is cooled at the cooling station. When the tooling with the PP transparent card is rotated to the second color injection station, it is aligned with the fixed mold of the injection molding machine. The HDPE injection plastic enters the injection cavity formed by the fixed mold and the tooling to perform injection molding of the second color cap. Finally, the injection-molded two-color anti-counterfeiting packaging cap is rotated to the ejection station by the cubic rotating center to complete the ejection operation. At this point, one production cycle of the product can be completed. After rotating another 90°, the next production cycle of the product can begin.

[0008] Thus, during product production, each station can operate in parallel, transforming the original sequential actions into synchronous superposition. This means that different stations can simultaneously perform injection molding, cooling, and product ejection operations, shortening the molding cycle and increasing efficiency by about 3 times, thereby achieving the goal of efficient and intelligent molding of the system.

[0009] Preferably, each tooling set is equipped with 48 molding cavities arranged in a matrix. The moving mold and the fixed mold of the injection molding machine have alignment cavities that correspond one-to-one with the 48 molding cavities. Thus, 48 ​​sets of products can be processed each time, realizing full utilization of equipment efficiency and doubling of production capacity.

[0010] Preferably, each tooling unit is equipped with an independent water-cooling channel, oil-push channel, and air-push channel. The cubic rotating center body is equipped with a water flow pipe, an oil flow pipe, and an air flow pipe. When the tooling unit rotates to the cooling position, the water flow circulates in the tooling unit at the corresponding cooling position through the water flow pipe and the water-cooling channel. When the tooling unit rotates to the ejection position, the oil flow circulates in the tooling unit at the corresponding ejection position through the oil flow pipe and the oil-push channel to perform the hydraulic cylinder pushing or retracting operation cycle. The air flow circulates in the tooling unit at the corresponding ejection position through the air flow pipe and the air-push channel to perform the air-blowing ejection and unloading operation.

[0011] Thus, the introduction of water can achieve cooling circulation, while the introduction of oil and air can provide the ejection operation required during injection molding production, such as oil pushing or air blowing. Furthermore, the independent cooling and exhaust channels corresponding to the molding cavity of each tooling can form a modular design to reduce maintenance difficulty and improve mold life.

[0012] Preferably, the end of the cubic rotation center body is further provided with a set of water-oil-gas integrated plates. The integrated plates contain integrated water pipes, integrated oil pipes, and integrated gas pipes corresponding to the interfaces of the water pipes, oil pipes, and gas pipes. The integrated water pipes, integrated oil pipes, and integrated gas pipes extend to the center end of the integrated plates and are further provided with water flow interfaces, oil flow interfaces, and gas flow interfaces that exit the integrated plates. These interfaces are located at different radii of rotation of the cubic rotation center body. At the bottom of the water-oil-gas integrated board, a set of water-oil-gas separation integrated blocks are also installed. The water-oil-gas separation integrated blocks are divided into water chambers, oil chambers and gas chambers. When the tooling rotates to the cooling position, the water chamber is connected to the water cooling channel of the tooling that has rotated to the cooling position to perform injection cooling of the product at the cooling position. When the tooling rotates to the ejection position, the oil chamber and gas chamber are connected to the oil flow pipe and air flow pipe that have rotated to the ejection position, respectively, to perform the working cycle of oil cylinder pushing or contracting and the ejection and unloading operation of air blowing.

[0013] At this point, when the cubic rotating center body is driven to rotate by the turntable, the water-oil-gas separation integrated block, which is externally connected to water, oil, and gas pipelines, can be in a positioning state. The water, oil, and gas pipelines are connected to the water, oil, and gas chambers that have been rotated to their positions. That is, when one set of fixtures rotates to the cooling station, the water chamber is connected to the water flow pipe of the corresponding cooling station, thus enabling the water flow. At the same time, another set of fixtures at the ejection station can achieve the corresponding oil and gas flow because the oil and gas chambers are connected to the oil and gas flow pipes of the corresponding ejection station. During this process, the water, gas, and oil lines are isolated from each other and can correspond to their respective stations. Therefore, during the 90° incremental rotation, the integration of water, gas, and oil lines can be better realized, avoiding pipeline redundancy.

[0014] Preferably, the linear reciprocating drive includes a set of support plates for supporting the injection molding machine's moving mold or the cubic rotating center body. The support plates are slidably mounted on the guide rail and driven by the linear drive group to perform linear reciprocating motion. Thus, during each 90° rotation transition, the injection molding machine's moving mold and the cubic rotating center body can be driven by their respective linear drive groups to perform linear motion, thereby achieving a rotatable gap between the cubic rotating center body and the injection molding machine's moving mold and the fixed mold of the injection molding machine. Then, after rotation, the injection molding machine's moving mold and the cubic rotating center body move in the opposite direction, realizing the alignment of the injection molding machine's moving mold and the fixed mold of the injection molding machine with the two sets of tooling to form the injection mold cavity.

[0015] Preferably, the linear reciprocating drive of the cubic rotation center further includes a turntable for driving the cubic rotation center to rotate. The turntable is provided with an external gear ring around its periphery. A drive motor is also provided on the support plate. The drive end of the drive motor is driven and connected to the external gear ring. A through hole is provided at the center of the turntable and the support plate for the water-oil-gas separation integrated block to pass through. The turntable is rotated and placed on the support plate.

[0016] Preferably, the linear drive assembly includes a linear rack mounted on the bottom of the support plate and a set of drive motors for meshing with the linear rack.

[0017] A four-sided rotating two-color intelligent mold forming method, based on the aforementioned four-sided rotating two-color intelligent mold forming system, includes the following steps:

[0018] S1: Initially, the four sets of tooling for the cubic rotation center body are sequentially aligned at the first color injection station, the cooling station, the second color injection station, and the ejection station;

[0019] S2: Then, the injection molding machine's moving mold and the cubic rotating center body are driven to make linear motion by the linear reciprocating drive component, so that a gap is formed between the injection molding machine's moving mold and the injection molding machine's fixed mold and the cubic rotating center body, which allows the cubic rotating center body to rotate.

[0020] S3: The injection molding machine's moving mold and cubic rotating center are driven in reverse, aligning the moving mold and the fixed mold with the two sets of tooling on opposite sides. At the first color injection station, the moving mold aligns with the tooling, and PP injection molding material is injected into the corresponding mold cavity for injection molding of the first color PP transparent card. After injection molding, the operation of S2 is repeated, and then the cubic rotating center is rotated 90°. The molded PP transparent card is then rotated to the cooling station for cooling. After both the first color injection station and the cooling station are completed, the operation of S2 is repeated again, and the cubic rotating center is rotated another 90°. The cooled PP transparent card is then rotated to the second color injection station. The injection molding machine's moving mold and cubic rotating center are then driven in reverse again, aligning the moving mold and the fixed mold with the two sets of tooling on opposite sides. At the second color injection station... At the injection molding station, the injection molding machine's fixed mold and tooling are aligned; HDPE injection molding material is injected into the corresponding mold cavity to mold the second-color cap. The first-color PP transparent card and the second-color cap are combined to form the finished two-color anti-counterfeiting packaging bottle cap. After the operations at the second-color injection molding station, the first-color injection molding station, and the cooling station are all completed, the operation S2 is repeated, and the cubic rotation center is rotated another 90°. The molded two-color anti-counterfeiting packaging bottle cap is then rotated to the ejection station for ejection from the tooling. This completes one production cycle of the two-color anti-counterfeiting packaging bottle cap. After the operations at the ejection station, the second-color injection molding station, the first-color injection molding station, and the cooling station are all completed, the operation S2 is repeated, and the cubic rotation center is rotated another 90° to continue the next production cycle of the two-color anti-counterfeiting packaging bottle cap.

[0021] The beneficial effects of this invention are:

[0022] This invention provides a four-sided rotating dual-color intelligent mold forming system and method, which, compared with traditional molds, has higher production efficiency, more precise molding quality, and can achieve synchronous superposition of actions between multiple workstations, adapting to more complex injection molding needs. The core component, the cubic rotating center body, has an integrated design of water, air, and oil circuits. Because this part needs to rotate directionally during operation, it serves as an umbilical part connecting the mold and the water, air, and oil circuits of the injection molding machine. This solves the design problem of such core components of rotating molds, enabling the exhaust and cooling efficiency and heat conduction efficiency of each side to reach a balance of 98%, achieving an industry-leading level.

[0023] In the production of dual-color anti-counterfeiting packaging bottle caps according to this invention, the first color is transparent PP material, and the second color is HDPE material. Four sets of tooling rotate sequentially through four stations: the first-color injection station, the cooling station, the second-color injection station, and the ejection station. At the first-color injection station, after the injection molding machine aligns with the tooling, the injection molding material enters the injection mold cavity formed by the injection molding machine and the tooling to perform injection molding of the PP transparent card. Then, the cubic rotation center continues to rotate through the tooling, driving the injection-molded PP transparent card to the cooling station, where the PP transparent card is cooled. When the tooling that has formed the PP transparent card continues to rotate to the second-color injection station, it... The injection molding machine aligns the fixed mold, and the HDPE injection plastic enters the injection cavity formed by the fixed mold and tooling for the injection molding of the second-color cap. Finally, the injection-molded two-color anti-counterfeiting packaging cap is rotated to the ejection station by the cubic rotating center to complete the ejection operation. This completes one production cycle of the product. After another 90° rotation, the next product production cycle begins. Thus, during product production, each station can operate in parallel, transforming the original sequential operation into synchronous superposition. That is, different stations can simultaneously perform injection, cooling, and product ejection operations, shortening the molding cycle and increasing efficiency by about 3 times, thereby achieving the goal of efficient and intelligent molding of the system.

[0039] Example 1

[0040] like Figure 1-12 As shown, a four-sided rotating dual-color intelligent mold forming system, in this embodiment, includes a central cubic rotating center body 1 and four sets of tooling evenly distributed around the periphery of the cubic rotating center body 1. The four sets of tooling are driven by the cubic rotating center body 1 to rotate synchronously in increments of 90° at equal intervals, so as to realize the alternating operation of the first color injection station 2, cooling station 3, second color injection station 4, and ejection station 5 in sequence. An injection molding machine motor 6 and an injection molding machine stationary mold 7 are also arranged at the first color injection station 2 and the second color injection station 4. The injection molding machine motor 6 and the cubic rotating center body 1 move linearly under the drive of their respective linear reciprocating drive components, so that after the cubic rotating center body 1 has rotated, the injection molding machine motor 6 and the injection molding machine stationary mold 7 are aligned with the two sets of tooling respectively. The alignment of the injection molding machine motor 6 with the tooling forms the mold cavity for the first color injection of the product, and the alignment of the injection molding machine stationary mold 7 with the tooling forms the mold cavity for the second color injection of the product.

[0041] In the production of two-color anti-counterfeiting packaging bottle caps, the first color is transparent PP material, and the second color is HDPE material. Four sets of tooling rotate sequentially through four stations: the first-color injection molding station 2, the cooling station 3, the second-color injection molding station 4, and the ejection station 5. At the first-color injection molding station 2, after the injection molding machine 6 aligns with the tooling, the injection plastic enters the injection mold cavity formed by the injection molding machine 6 and the tooling to perform injection molding of the PP transparent card 19. Then, the cubic rotation center 1 continues to rotate through the tooling, driving the injection-molded PP transparent card 19 to rotate to the cooling station 3. The PP transparent card 19 is cooled at the cooling station 3. When the tooling with the PP transparent card 19 is rotated to the second color injection station 4, it is aligned with the fixed mold 7 of the injection molding machine. The HDPE injection plastic enters the injection mold cavity formed by the fixed mold 7 and the tooling to perform injection molding of the second color cap 20. Finally, the injection-molded two-color anti-counterfeiting packaging cap is rotated to the ejection station 5 by the cubic rotating center body 1 to complete the ejection operation. Thus, one production cycle of the product can be completed. After rotating an additional 90°, the next production cycle of the product can begin.

[0042] Thus, during product production, each station can operate in parallel, transforming the original sequential actions into synchronous superposition. This means that different stations can simultaneously perform injection molding, cooling, and product ejection operations, shortening the molding cycle and increasing efficiency by about 3 times, thereby achieving the goal of efficient and intelligent molding of the system.

[0043] Each tooling set has 48 molding cavities 8 arranged in a matrix. The injection molding machine's moving mold 6 and the injection molding machine's stationary mold 7 have alignment cavities that correspond one-to-one with the 48 molding cavities 8. Thus, 48 ​​sets of products can be processed each time, realizing full utilization of equipment efficiency and doubling of production capacity.

[0044] Each tooling unit is equipped with independent water cooling channels, oil pushing channels, and air pushing channels. The cubic rotating center body 1 is equipped with water flow pipes, oil flow pipes, and air flow pipes. When the tooling unit rotates to the cooling station 3, the water flow circulates in the tooling unit at the corresponding cooling station 3 through the water flow pipes and water cooling channels. When the tooling unit rotates to the ejection station 5, the oil flow circulates in the tooling unit at the corresponding ejection station 5 through the oil flow pipes and oil pushing channels to perform the oil cylinder pushing or retracting operation cycle. The air flow circulates in the tooling unit at the corresponding ejection station 5 through the air flow pipes and air pushing channels to perform the air blowing ejection and unloading operation.

[0045] Thus, the introduction of water can achieve cooling circulation, while the introduction of oil and air can provide the ejection operation required during injection molding production, and the independent cooling and exhaust channels corresponding to the molding cavity 8 of each tooling can also form a modular design to reduce maintenance difficulty and improve mold life.

[0046] The end of the cubic rotating center body 1 is also provided with a set of water-oil-gas integrated plates 9. The integrated plates 9 contain integrated water pipes 91, integrated oil pipes 92, and integrated gas pipes 93 corresponding to the interfaces of the water pipe, oil pipe, and gas pipe. The integrated water pipes 91, integrated oil pipes 92, and integrated gas pipes 93 extend to the center end of the integrated plates 9 and are further provided with water flow interfaces 94, oil flow interfaces 95, and gas flow interfaces 96 (e.g., ...) that pass through the integrated plates 9. Figure 7 As shown, the integrated water pipe 91, integrated oil pipe 92, and integrated air pipe 93, as well as the water flow interface 94, oil flow interface 95, and air flow interface 96, are distinguished by circles of different diameters (the diameters of the integrated water pipe 91, integrated oil pipe 92, and integrated air pipe 93 decrease sequentially). The water flow interface 94, oil flow interface 95, and air flow interface 96 correspond to different radii of rotation of the cubic rotation center body 1. A set of water-oil-gas separators is also connected and installed at the bottom of the integrated water-oil-gas circuit plate 9. The integrated water-oil-gas separation block 10 is divided into water chamber 11, oil chamber 12 and gas chamber 13. When the tooling rotates to the cooling station 3, the water chamber 11 is connected to the water cooling channel of the tooling rotated to the cooling station 3 to perform injection cooling of the product at the cooling station 3. When the tooling rotates to the ejection station 5, the oil chamber 12 and gas chamber 13 are connected to the oil flow pipe and air flow pipe of the ejection station 5 respectively to perform the working cycle of oil cylinder pushing or contraction and air blowing ejection and unloading operation.

[0047] At this point, when the cubic rotating center 1 is driven to rotate by the turntable 17, the water-oil-gas separation integrated block 10, which is externally connected to water, oil, and gas pipelines, can be in a positioning state. The water, oil, and gas pipelines are connected to the water chamber 11, oil chamber 12, and gas chamber 13 that have been rotated to their positions. That is, when one set of fixtures rotates to the cooling station 3, the water chamber 11 is connected to the water flow pipe of the corresponding cooling station 3, so the water path can be opened. At the same time, another set of fixtures is located at the ejection station 5. Since the oil chamber 12 and gas chamber 13 are connected to the oil flow pipe and air flow pipe of the corresponding ejection station 5, the corresponding oil and gas paths can be opened. During this process, the water, gas, and oil paths are isolated from each other and can correspond to their respective stations. Therefore, in the 90° incremental rotation, the integration of water, gas, and oil paths can be better realized, and the redundancy of pipelines can be avoided.

[0048] The linear reciprocating drive includes a set of support plates 14 for supporting the injection molding machine mold 6 or the cubic rotation center 1. The support plates 14 are slidably mounted on the guide rail 15 and are driven by the linear drive group to perform linear reciprocating motion. Thus, during each 90° rotation transition, the injection molding machine mold 6 and the cubic rotation center 1 can be driven by their respective linear drive groups to perform linear motion, so as to achieve a rotatable gap between the cubic rotation center 1, the injection molding machine mold 6, and the injection molding machine fixed mold 7. Then, after rotation, the injection molding machine mold 6 and the cubic rotation center 1 move in the opposite direction, so as to achieve the alignment of the injection molding machine mold 6 and the injection molding machine fixed mold 7 with the two sets of tooling to form the injection cavity.

[0049] The linear reciprocating drive of the cubic rotation center 1 also includes a turntable 17 for driving the cubic rotation center 1 to rotate. The turntable 17 is provided with an external gear ring 16 around its periphery. A drive motor is also provided on the support plate 14. The drive end of the drive motor is drivenly connected to the external gear ring 16. A through hole 18 is provided at the center of the turntable 17 and the support plate 14 for the water-oil-gas separation integrated block 10 to pass through. The turntable 17 is rotatably placed on the support plate 14.

[0050] The linear drive assembly includes a linear rack mounted on the bottom of the support plate 14 and a set of drive motors for meshing with the linear rack.

[0054] S2: Then, the injection molding machine 6 and the cubic rotation center 1 are driven to make linear motion by the linear reciprocating drive component, so that a gap is formed between the injection molding machine 6 and the injection molding machine fixed mold 7 and the cubic rotation center 1, which allows the cubic rotation center 1 to rotate.

[0055] S3: The injection molding machine 6 and the cubic rotation center 1 are driven in reverse, so that the injection molding machine 6 and the fixed mold 7 are aligned with the two sets of tooling on the opposite sides. At the first color injection station 2, the injection molding machine 6 is aligned with the tooling, and PP injection molding material is injected into the corresponding mold cavity for injection molding of the first color PP transparent card 19. After injection molding is completed, the operation of S2 is repeated, and then the cubic rotation center 1 is rotated 90°. The molded PP transparent card 19 is then rotated to the cooling station 3 for cooling. After the operation of the first color injection station 2 and the cooling station 3 is completed, the operation of S2 is repeated again, and the cubic rotation center 1 is rotated another 90°. The cooled PP transparent card 19 is then rotated to the second color injection station 4, and then the injection molding machine 6 and the cubic rotation center 1 are driven in reverse again, so that the injection molding machine 6 and the fixed mold 7 are aligned with the two sets of tooling on the opposite sides. At the two-color injection molding station 4, the injection molding machine's fixed mold 7 is aligned with the tooling. HDPE injection molding material is injected into the corresponding mold cavity to form the second-color cap 20. The first-color PP transparent card 19 and the second-color cap 20 are combined to form the finished two-color anti-counterfeiting packaging bottle cap. After the operations at the second-color injection molding station 4, the first-color injection molding station 2, and the cooling station 3 are completed, the operation S2 is repeated, and the cubic rotation center 1 is rotated another 90°. The finished two-color anti-counterfeiting packaging bottle cap is then rotated to the ejection station 5 for ejection and removal from the tooling. This completes one production cycle of the finished two-color anti-counterfeiting packaging bottle cap.

Each set of tooling is equipped with independent water cooling channels, oil pushing channels, and air pushing channels. The cubic rotating center body is equipped with water flow pipes, oil flow pipes, and air flow pipes. When the tooling rotates to the cooling position, the water flows through the water flow pipes and water cooling channels to circulate in the tooling at the corresponding cooling position. When the tooling rotates to the ejection position, the oil flows through the oil flow pipes and oil pushing channels to circulate in the tooling at the corresponding ejection position for the operation cycle of oil cylinder pushing or retraction. The air flow flows through the air flow pipes and air pushing channels to perform air blowing ejection and unloading operations in the tooling at the corresponding ejection position. At the end of the cubic rotation center body, a set of integrated water-oil-gas circuit plates is also provided. Within these integrated plates, integrated water pipes, integrated oil pipes, and integrated gas pipes are arranged, corresponding to the interfaces of water pipes, oil pipes, and gas pipes. Extending to the center end of the integrated water-oil-gas circuit plates, the integrated water pipes, integrated oil pipes, and integrated gas pipes are further provided with water flow interfaces, oil flow interfaces, and gas flow interfaces that exit the integrated plates. These interfaces are located at different radii of rotation of the cubic rotation center body. At the bottom of the oil-gas circuit integrated board, a set of water-oil-gas separation integrated blocks are also installed. The water-oil-gas separation integrated blocks are divided into water chambers, oil chambers and gas chambers. When the tooling rotates to the cooling position, the water chamber is connected to the water cooling channel of the tooling that has rotated to the cooling position to cool the injection molding of the product at the cooling position. When the tooling rotates to the ejection position, the oil chamber and gas chamber are connected to the oil flow pipe and air flow pipe that have rotated to the ejection position, respectively, to perform the working cycle of oil cylinder pushing or contracting and the ejection and unloading operation of air blowing.

6. A method for forming a four-sided rotating two-color intelligent mold, based on the four-sided rotating two-color intelligent mold forming system according to any one of claims 1-5, characterized in that, Includes the following steps: S1: Initially, the four sets of tooling for the cubic rotation center body are sequentially aligned at the first color injection station, the cooling station, the second color injection station, and the ejection station; S2: Then, the injection molding machine's moving mold and the cubic rotating center body are driven to make linear motion by the linear reciprocating drive component, so that a gap is formed between the injection molding machine's moving mold and the injection molding machine's fixed mold and the cubic rotating center body, which allows the cubic rotating center body to rotate. S3: The injection molding machine's moving mold and cubic rotating center are driven in reverse, aligning the moving mold and the fixed mold with the two sets of tooling on opposite sides. At the first color injection station, the moving mold aligns with the tooling, and PP injection molding material is injected into the corresponding mold cavity for injection molding of the first color PP transparent card. After injection molding, the operation of S2 is repeated, and then the cubic rotating center is rotated 90°. The molded PP transparent card is then rotated to the cooling station for cooling. After both the first color injection station and the cooling station are completed, the operation of S2 is repeated again, and the cubic rotating center is rotated another 90°. The cooled PP transparent card is then rotated to the second color injection station. The injection molding machine's moving mold and cubic rotating center are then driven in reverse again, aligning the moving mold and the fixed mold with the two sets of tooling on opposite sides. At the second color injection station... At the injection molding station, the injection molding machine's fixed mold and tooling are aligned; HDPE injection molding material is injected into the corresponding mold cavity to mold the second-color cap. The first-color PP transparent card and the second-color cap are combined to form the finished two-color anti-counterfeiting packaging bottle cap. After the operations at the second-color injection molding station, the first-color injection molding station, and the cooling station are all completed, the operation S2 is repeated, and the cubic rotation center is rotated another 90°. The molded two-color anti-counterfeiting packaging bottle cap is then rotated to the ejection station for ejection from the tooling. This completes one production cycle of the two-color anti-counterfeiting packaging bottle cap. After the operations at the ejection station, the second-color injection molding station, the first-color injection molding station, and the cooling station are all completed, the operation S2 is repeated, and the cubic rotation center is rotated another 90° to continue the next production cycle of the two-color anti-counterfeiting packaging bottle cap.
