Description

Technical Field

[0001] The present application belongs to the technical field of molding equipment, and more specifically, relates to a water transport jacket and a molding machine. Background Art

[0002] Existing multi-station molding machines feature multiple rotating stations. This configuration minimizes the cooling time after molding, thereby improving production efficiency. Multi-station molding machines also enable rapid switching between different production processes for multi-material and / or complex products, enabling continuous and rapid production.

[0003] In actual production, different processes often have different requirements for molding conditions, so it is necessary to make appropriate adjustments to the molding conditions in the mold. The most common adjustment is to adjust the temperature of the mold. For example, when the temperature needs to be increased, the mold is heated; when the temperature in the mold needs to be cooled, a water jacket is set outside the mold to connect the corresponding cooling pipeline to cool the mold.

[0004] Furthermore, during the production process, semi-finished products formed after the previous process often require further processing before they can be processed for secondary molding. For example, during multiple consecutive injection molding processes, the sprue on the semi-finished product formed after the previous injection molding process must be removed before the semi-finished product can proceed to the next molding process. Of course, there are also other situations, such as semi-finished products requiring core pulling before secondary molding. For some semi-finished products with special structures, due to space and precision constraints, they often cannot be processed by automated equipment outside the mold before secondary molding, and the automated equipment must be installed inside the mold. The mold on the multi-station molding machine will rotate continuously during the production process. Pipes are set on the water transport jacket to input the corresponding medium into the mold to control the automated equipment in the mold. Because the water transport jacket is mainly used to input cooling medium into the mold and output the heated cooling medium, different media have different temperature requirements for the use environment. After the different medium delivery channels are integrated and installed on a water transport jacket, the heat conduction effect of the water transport jacket will cause the temperatures of the various media to affect each other, which is not conducive to ensuring the normal use temperature of various media, thereby possibly reducing the use effect or life of the medium, and is not conducive to the long-term stable operation of the molding machine. Summary of the Invention

[0005] One of the purposes of the embodiments of the present application is to provide a water transport jacket, aiming to solve the technical problem in the prior art that different media transported in the water transport jacket have mutual influences, making it difficult to meet process requirements.

[0015] In one embodiment, the rotor comprises at least:

[0016] a first rotating ring, sleeved on the base, the first movable interface being provided on the first rotating ring, and the first conveying groove being provided on the inner peripheral wall of the first rotating ring or the outer peripheral wall of the base;

[0017] The second rotating ring is sleeved on the first fixed sleeve, the second movable interface is arranged on the second rotating ring, and the second conveying groove is opened on the inner peripheral wall of the second rotating ring or the outer peripheral wall of the first fixed sleeve.

[0020] In one embodiment, the water transport jacket further includes a joint structure, which includes a fixed part fixed on the base and a rotating part fixed on the rotor, the rotating part being sleeved on the fixed part and rotatable around the fixed part; the fixed part is provided with a plurality of conductive brushes for conducting with an external power supply device, and the rotating part is provided with a plurality of metal rings for forming an electrical connection with the electrical components in the mold, and the plurality of conductive brushes are in one-to-one contact and conduction with the plurality of metal rings when the rotating part rotates around the fixed part.

[0021] The water transport sleeve provided by the present application has the following advantages: compared with the prior art, the present application provides a first conveying groove on the rotor or base, and a second conveying groove on the rotor or the first fixed sleeve. The annular first conveying groove enables the first flow channel to be connected to the pipeline on the first movable interface in real time, and the annular second conveying groove enables the second flow channel to be connected to the pipeline on the second movable interface in real time. As a result, when the rotor rotates around the stator, the external pipelines connected to the first and second flow channels can be connected to the pipelines provided on the mold (including at least one of the cooling pipeline, air pipeline, and oil pipeline), ensuring the medium transportation between the external pipeline and the mold, and facilitating the transportation of the corresponding medium into the mold during operation of the molding machine. The first fixed sleeve is connected to the base, so that the base and the first fixed sleeve are independent of each other, and the first flow channel and the second flow channel are also independent of each other, which can ensure that the temperatures of the media passing through the first and second flow channels have little effect on each other, reducing the impact on media with different temperature requirements when passing through the stator, thereby improving the use effect of the medium passing through the water transport sleeve and meeting the requirements of the corresponding process.

[0022] The present application also provides a forming machine comprising any of the above-mentioned water transport jackets.

[0023] The molding machine provided by the present application is configured so that when the rotor rotates around the stator, the external pipelines connected to the first and second flow channels can be connected to the pipelines provided on the mold (including at least one of the cooling pipelines, air pipes, and oil pipes), thereby ensuring the medium transportation between the external pipelines and the mold, and facilitating the transportation of the corresponding medium into the mold during operation of the molding machine. The first fixed sleeve is sleeved on the base, and the base and the first fixed sleeve are independent of each other, and the first and second flow channels are also independent of each other, which can ensure that the temperatures of the media passing through the first and second flow channels have almost no mutual influence, reducing the impact of media of different temperatures passing through the stator, thereby improving the use effect of the medium passing through the water transport sleeve and meeting the requirements of the corresponding process;

[0024] At the same time, the relative positions of the stator base, the first fixing sleeve, the second fixing sleeve and the third fixing sleeve in the circumferential direction are not fixed before they are successively sleeved and fixed, or in other words, different fixing sleeves can be rotated circumferentially around the axis of the fixing sleeve for a certain angle when they are sleeved and fixed. In this way, the relative positions of the flow channels (the first flow channel, the second flow channel, the third flow channel and the fourth flow channel) between the fixing sleeves on the stator can be adjusted according to actual needs before the stator is sleeved and fixed. Even if the base, the first fixing sleeve, the second fixing sleeve and the third fixing sleeve have been processed, the relative positions of the flow channels on the different fixing sleeves on the stator can still be adjusted, so as to facilitate better compatibility between the internal installation space of the molding machine and the connection position of the external pipeline, reduce the requirements of the internal space of the molding machine and the external pipeline for the setting position of the stator flow channel, thereby facilitating the installation of the stator, and facilitating the batch production and storage of stator accessories in advance, which is beneficial to saving the production cycle of the entire molding machine.

[0037] In order to illustrate the technical solution described in this application, the following is a detailed description with reference to specific drawings and embodiments.

[0038] Please also refer to Figures 1 to 3 The water transport jacket provided in an embodiment of the present application will now be described. The water transport jacket provided in an embodiment of the present application is used in a multi-station molding machine, which includes a turntable 6 and multiple molds 7 disposed on the turntable 6. The water transport jacket includes a stator 1 and a rotor 2 sleeved on the stator 1. The stator 1 and rotor 2 have smooth, coaxial mating surfaces. The lower end of the rotor 2 is fixedly connected to the turntable 6, allowing the rotor 2 to rotate circumferentially around the stator 1 along with the turntable 6.

[0039] In this embodiment, the stator 1 includes a base 11, and at least one first fixing sleeve 12 is sleeved on the outer peripheral wall of the base 11. Here, the stator 1 can be composed of only the base 11 and the first fixing sleeve 12, or can be composed of the base 11, the first fixing sleeve 12 and at least one other fixing sleeve; when the stator 1 includes at least one other fixing sleeve, the base 11 has the smallest inner diameter, the first fixing sleeve 12 has the second largest inner diameter, and the inner diameter of the other fixing sleeve with the smallest inner diameter is larger than the minimum outer diameter of the first fixing sleeve 12. The inner diameter of each other fixing sleeve is different, and the inner diameter of the fixing sleeve with a larger inner diameter is larger than the minimum outer diameter of the other fixing sleeves with a smaller inner diameter. The base 11, the first fixing sleeve 12 and the at least one other fixing sleeve are nested in sequence according to the size of the inner diameter. The base 11 is provided with a first flow channel 111 , and the first fixing sleeve 12 is provided with a second flow channel 121 . The first flow channel 111 and the second flow channel 121 are independent of each other and are respectively used to connect to external pipelines. External media can be input into the first flow channel 111 or the second flow channel 121 through the external pipelines. Among them, the first flow channel 111 and the second flow channel 121 are both internally hollow turning flow channels, one end of the first flow channel 111 passes through one axial end of the base 11, and the other end of the first flow channel 111 passes through the outer peripheral wall of the base 11 and is arranged adjacent to the end face of the other axial end of the base 11, and one end of the first flow channel 111 has a first fixed interface 112, and the first fixed interface 112 is used to connect an external pipeline; one end of the second flow channel 121 passes through one axial end of the first fixed sleeve 12, and the other end of the second flow channel 121 passes through the outer peripheral wall of the first fixed sleeve 12 and is arranged adjacent to the end face of the other axial end of the first fixed sleeve 12, and one end of the second flow channel 121 has a second fixed interface 122, and the second fixed interface 122 is used to connect an external pipeline.

[0040] The rotor 2 is simultaneously sleeved around the base 11 and the first fixed sleeve 12 and is capable of rotating around both the base 11 and the first fixed sleeve 12. The rotor 2 is provided with a first movable interface 212 and a second movable interface 222 spaced apart along the axial direction. The first movable interface 212 and the second movable interface 222 are respectively used to connect to pipelines (including at least one of a cooling pipeline, an air pipeline, and an oil pipeline) provided on the mold 7. An annular first conveying groove 211 and an annular second conveying groove 221 are formed on the inner circumferential wall of the rotor 2. The first conveying groove 211 and the second conveying groove 221 are spaced apart along the axial direction of the rotor 2. The first conveying groove 211 is circumferentially arranged along the outer circumferential wall of the base 11 and communicates with the end of the first flow channel 111 away from the first fixed interface 112. The second conveying groove 221 is circumferentially arranged along the outer circumferential wall of the first fixed sleeve 12 and communicates with the end of the second flow channel 121 away from the second fixed interface 122. When the rotor 2 rotates around the stator 1, the first flow channel 111 can be connected to the first conveying groove 211 in real time, and the second flow channel 121 can be connected to the second conveying groove 221 in real time, and the first conveying groove 211 is connected to the first movable interface 212, and the second conveying groove 221 is connected to the second movable interface 222, then the external pipeline can be connected to the mold 7 in real time through the first flow channel 111, the first conveying groove 211, the first movable interface 212 and the connecting pipeline (not shown) in sequence, and the external pipeline can also be connected to the mold 7 in real time through the second flow channel 121, the second conveying groove 221, the second movable interface 222 and the connecting pipeline in sequence, and the medium in the external pipeline can enter the mold 7 through the first flow channel 111 or the second flow channel 121 when the molding machine is working.

[0041] In another embodiment, the first conveying groove 211 can also be opened on the outer peripheral wall of the base 11, or the first conveying groove 211 can be opened on the inner peripheral wall of the rotor 2 and the outer peripheral wall of the base 11 at the same time; the second conveying groove 221 can also be opened on the outer peripheral wall of the first fixed sleeve 12, or the second conveying groove 221 can be opened on the inner peripheral wall of the rotor 2 and the outer peripheral wall of the first fixed sleeve 12 at the same time.

[0042] In the embodiment of the present application, a first conveying groove 211 is provided on the rotor 2 or the base 11, and a second conveying groove 221 is provided on the rotor 2 or the first fixed sleeve 12. The annular first conveying groove 211 can enable the first flow channel 111 to be connected to the pipeline on the first movable interface 212 in real time, and the annular second conveying groove 221 can enable the second flow channel 121 to be connected to the pipeline on the second movable interface 222 in real time, so that the rotor 2 rotates around the stator 1 following the turntable 6. The external pipelines connected to the first flow channel 111 and the second flow channel 121 can be connected to the mold 7, ensuring the medium transportation between the external pipeline and the mold 7, which is convenient for the molding machine to transport the corresponding medium into the mold 7. The first fixed sleeve 12 is sleeved onto the base 11, making the base 11 and the first fixed sleeve 12 independent of each other. Accordingly, the first flow channel 111 and the second flow channel 121 are also independent of each other. When the first flow channel 111 and the second flow channel 121 are used to transport media with different temperatures, the base 11 and the first fixed sleeve 12 are independent of each other. This ensures that the temperatures of the media passing through the first flow channel 111 and the second flow channel 121 have little effect on each other, reducing the impact of media with different temperature requirements on passing through the stator 1. This ensures that the temperature change of the media after passing through the stator 1 is within the required range, improving the effectiveness of the media passing through the water transport sleeve, and reducing the impact of temperature on the fluidity and service life of some oil-based media. Furthermore, the base 11 and the first fixed sleeve 12 are sleeved axially during assembly, simplifying the connection relationship of the stator 1 and facilitating the installation and replacement of the stator 1.

[0043] Specifically, the base 11 and the first fixed sleeve 12 are independent of each other and are arranged in a socketed manner, so the base 11 and the first fixed sleeve 12 can be independently arranged and are different fixed sleeves. The flow channel on the same fixed sleeve can be used to transport media with substantially the same temperature. Substantially the same here means that the temperature requirements are the same or similar. For example, the two transported media require room temperature. Although the actual temperatures of the two are different during the transportation process, the difference is not large, and the same fixed sleeve can be used for transportation. Different fixed sleeves can transport the same or different media, so the base 11 and the first fixed sleeve 12 can be used to transport the same or different media. Therefore, the first flow channel 111 and the second flow channel 121 can be used to transport the same or different media. Then, according to specific usage requirements, the materials of the base 11 and the first fixed sleeve 12 can be set to be the same or different according to actual needs. This can save costs and facilitate processing while meeting the requirements of medium transmission. For example, if the first flow channel 111 of the base 11 is used to transport coolant, the base 11 can be made of a material with low thermal conductivity, such as white steel or bakelite. For example, if the second flow channel 121 is used to transport coolant after absorbing heat, the first fixing sleeve 12 can be made of a material with average or high thermal conductivity, and does not have to be the same material as the base 11. Of course, when the first flow channel 111 or the second flow channel 121 is used to transport other media, appropriate materials can be set according to actual needs, which will not be detailed here.

[0044] It should be noted that the external pipeline includes at least one of an air pipe, an oil pipe, a hot water pipe, and a cold water pipe. The first flow channel 111 can be used to connect at least one of the air pipe, the oil pipe, the hot water pipe, and the cold water pipe, and the second flow channel 121 can be used to connect at least one of the air pipe, the oil pipe, the hot water pipe, and the cold water pipe, so as to facilitate the real-time connection between the air pipe, the oil pipe, the hot water pipe, or the cold water pipe and the connecting pipeline to the mold 7. Among them, the access to the air pipe can realize the control of the pneumatic components in the mold 7; the access to the oil pipe can realize the lubrication of the devices in the mold 7 or the hydraulic control of the hydraulic components; the access to the hot water pipe is conducive to the discharge of the cooling liquid with a high temperature formed by the absorption of heat after the mold 7 is cooled; the access to the cold water pipe is conducive to the input of the cooling liquid. The type of external pipeline used to connect the first flow channel 111 and the second flow channel 121 can be set according to the specific needs of the mold 7. For example, when the mold 7 only needs to be cooled, a hot water pipe and a cold water pipe can be connected to the first flow channel 111 and the second flow channel 121 respectively. When the mold 7 needs to be hydraulically and pneumatically controlled, an oil pipe and an air pipe can be connected to the first flow channel 111 and the second flow channel 121 respectively. Of course, there can also be other combinations, which will not be elaborated here.

[0045] Specifically, bearings 8 are provided at the rotational connection between the stator 1 and the rotor 2 to reduce friction between the stator 1 and the rotor 2. In this embodiment, bearings 8 are positioned near the turntable 6 on the rotor 2. In other embodiments, bearings 8 may be positioned in other locations as long as they facilitate the rotational connection between the rotor 2 and the mover. The number and specifications of bearings 8 may also be selected based on actual needs.

[0046] In one embodiment, please refer to Figure 3 and Figure 4The first fixing sleeve 12 is at least sleeved with a second fixing sleeve 13. The first fixing sleeve 12 is arranged between the base 11 and the second fixing sleeve 13. The base 11, the first fixing sleeve 12 and the second fixing sleeve 13 are sleeved in sequence, which simplifies the installation of the stator 1. The second fixing sleeve 13 is provided with a third flow channel 131 for connecting to an external pipeline. The third flow channel 131 is independent of the first flow channel 111 and the second flow channel 121. The external medium can enter the third flow channel 131 through the external pipeline. Among them, the third flow channel 131 is an internally hollow turning flow channel. One end of the third flow channel 131 passes through one axial end of the second fixing sleeve 13, and the other end of the third flow channel 131 passes through the outer peripheral wall of the second fixing sleeve 13 and is arranged near the end face of the other axial end of the second fixing sleeve 13. One end of the third flow channel 131 is connected to a third fixing interface 132, and the third fixing interface 132 is used to connect to an external pipeline. The rotor 2 is sleeved outside the second fixed sleeve 13 and is capable of rotating around the second fixed sleeve 13. The rotor 2 is provided with a third movable interface 232 for connecting to the mold 7 via a connecting pipeline. The first movable interface 212, the second movable interface 222, and the third movable interface 232 are arranged at intervals along the rotor 2. An annular third conveying groove 231 is defined on the inner circumferential wall of the rotor 2. The first conveying groove 211, the second conveying groove 221, and the third conveying groove 231 are spaced apart along the axial direction of the rotor 2. The third conveying groove 231 is circumferentially arranged along the outer circumferential wall of the second fixed sleeve 13 and communicates with the end of the third flow channel 131 away from the third fixed interface 132. When the rotor 2 rotates around the stator 1, the third flow channel 131 can be connected to the third conveying groove 231 in real time, and the third conveying groove 231 is connected to the third movable interface 232. The third movable interface 232 is connected to the pipeline (including at least one of the cooling pipeline, air pipe, and oil pipe) set on the mold 7 through the connecting pipeline. The external pipeline can be connected to the mold 7 in real time through the third flow channel 131, the third conveying groove 231, the third movable interface 232 and the connecting pipeline in sequence, so that the medium in the external pipeline can enter the mold 7 through the third flow channel 131 when the molding machine is working.

[0047] In another embodiment, the third conveying groove 231 is opened on the outer peripheral wall of the second fixed sleeve 13 ; alternatively, the third conveying groove 231 can also be opened on both the inner peripheral wall of the rotor 2 and the outer peripheral wall of the second fixed sleeve 13 .

[0048] Specifically, the third flow channel 131 can be used to connect at least one of an air pipe, an oil pipe, a hot water pipe, and a cold water pipe. The third flow channel 131 is independent of the first flow channel 111 and the second flow channel 121, respectively, to ensure that the temperatures of the media passing through the first flow channel 111, the second flow channel 121, and the third flow channel 131 have almost no mutual influence, reducing the impact on media with different temperature requirements when passing through the stator 1, and ensuring that the temperature change of the media after passing through the stator 1 is within the normal required range. The third flow channel 131 can transport the same or different media as the first flow channel 111 and the second flow channel 121. Depending on the specific transported medium, the material of the second fixed sleeve 13 can be set to be the same or different from that of the base 11 and the first fixed sleeve 12. Under the premise of meeting the medium transmission requirements, it saves costs and facilitates processing.

[0049] In one embodiment, please refer to Figure 3 and Figure 4At least one third fixing sleeve 14 is sleeved onto the outer circumferential wall of the second fixing sleeve 13. The stator 1 then comprises a base 11, a first fixing sleeve 12, a second fixing sleeve 13, and a third fixing sleeve 14, which are sleeved in sequence. During stator assembly, the base 11, first fixing sleeve 12, second fixing sleeve 13, and third fixing sleeve 14 are sleeved in sequence along the axial direction, simplifying the installation of the entire stator 1. The third fixing sleeve 14 defines a fourth flow channel 141 for connecting to an external pipeline. External media can enter the fourth flow channel 141 through the external pipeline. The fourth flow channel 141 is independent of the first flow channel 111, the second flow channel 121, and the third flow channel 131, respectively. This ensures that the temperatures of the media passing through the first flow channel 111, the second flow channel 121, the third flow channel 131, and the fourth flow channel 141 have little to no mutual influence, reducing the impact on media with different temperature requirements when passing through the stator 1 and ensuring that the temperature change of the media after passing through the stator 1 remains within the required range. The fourth flow channel 141 is also configured as an internally hollow, curved flow channel. One end of the fourth flow channel 141 extends through one axial end of the third fixed sleeve 14, while the other end extends through the outer peripheral wall of the third fixed sleeve 14 and is positioned adjacent to the end surface of the other axial end of the third fixed sleeve 14. One end of the fourth flow channel 141 is connected to a fourth fixed interface 142 for connecting to an external pipeline. The rotor 2 is sleeved outside the third fixed sleeve 14 and is rotatable about the third fixed sleeve 14. The rotor 2 is provided with a fourth movable interface 242 for connecting to the mold 7 via a connecting pipeline. The first movable interface 212, the second movable interface 222, the third movable interface 232, and the fourth movable interface 242 are arranged in sequence. An annular fourth conveying groove 241 is provided on the inner circumferential wall of the rotor 2. The first conveying groove 211, the second conveying groove 221, the third conveying groove 231, and the fourth conveying groove 241 are spaced apart in sequence. The fourth conveying groove 241 is circumferentially arranged along the outer circumferential wall of the third fixed sleeve 14, and the fourth conveying groove 241 is connected to the end of the fourth flow channel 141 away from the fourth fixed interface 142. When the rotor 2 rotates around the stator 1, the fourth flow channel 141 can be connected to the fourth conveying groove 241 in real time, and the fourth conveying groove 241 is connected to the fourth movable interface 242. The fourth movable interface 242 is connected to the pipeline provided on the mold 7 (including at least one of a cooling pipeline, an air pipeline, and an oil pipeline) via a connecting pipeline. The external pipeline can then be connected to the mold 7 in real time through the fourth flow channel 141, the fourth conveying groove 241, the fourth movable interface 242, and the connecting pipeline. This allows the medium in the external pipeline to enter the mold 7 through the fourth flow channel 141 when the molding machine is in operation.

[0050] In another embodiment, the fourth conveying groove 241 is formed on the outer peripheral wall of the third fixing sleeve 14 , or the fourth conveying groove 241 is formed on both the inner peripheral wall of the rotor 2 and the outer peripheral wall of the third fixing sleeve 14 .

[0051] Specifically, the fourth flow channel 141 can be used to connect at least one of an air pipe, an oil pipe, a hot water pipe, and a cold water pipe. The fourth flow channel 141 can transport the same or different media as the first flow channel 111, the second flow channel 121, and the third flow channel 131. Depending on the specific medium being transported, the material of the third fixing sleeve 14 can be the same or different from that of the base 11, the first fixing sleeve 12, and the second fixing sleeve 13. This allows for cost savings and ease of processing while ensuring the proper medium transport.

[0052] As described above, the stator 1 includes a base 11, a first fixing sleeve 12, a second fixing sleeve 13, and a third fixing sleeve 14. The four fixing sleeves (i.e., the base 11, the first fixing sleeve 12, the second fixing sleeve 13, and the third fixing sleeve 14) are sequentially connected so that the flow channels (i.e., the first flow channel 111, the second flow channel 121, the third flow channel 131, and the fourth flow channel 141) on the four fixing sleeves (i.e., the base 11, the first fixing sleeve 12, the second fixing sleeve 13, and the third fixing sleeve 14) are mutually independent. This reduces the mutual influence of the temperature of the medium passing through the four fixing sleeves (i.e., the base 11, the first fixing sleeve 12, the second fixing sleeve 13, and the third fixing sleeve 14), improves the efficiency of the water transport sleeve in transporting the medium, so that the medium passing through each flow channel can meet the production requirements of the molding machine, and is also conducive to ensuring the fluidity and service life of some oil media, preventing the fluidity of the oil medium from being affected by excessively low temperature, or preventing the oil medium from being accelerated to decompose and deteriorate due to excessively high temperature, thereby reducing the service effect and service life.

[0053] In actual applications, corresponding fixed sleeves can be set according to specific needs. For example, when two media need to be conveyed, only the base 11 and the first fixed sleeve 12 need to be set; when three media need to be conveyed, the base 11, the first fixed sleeve 12 and the second fixed sleeve 13 can be set; when four media need to be conveyed, the base 11, the first fixed sleeve 12, the second fixed sleeve 13 and the third fixed sleeve 14 can be set in sequence; of course, according to the specific needs of the transport medium, the rotor 2 can also include a fourth fixed sleeve, a fifth fixed sleeve...Mth fixed sleeve, M≥four, at this time the flow channel, the conveying trough and the movable interface can also be set accordingly.

[0054] For details, please refer to Figure 4 and Figure 5The inner circumferential wall of the rotor 2 is recessed with a plurality of annular grooves 3. The grooves 3 are arranged in an annular shape and are respectively distributed on the upper and lower sides of the first conveying groove 211, the second conveying groove 221, the third conveying groove 231, and the fourth conveying groove 241. In other words, the grooves 3 are respectively distributed on the upper and lower sides of the first flow channel 111, the second flow channel 121, the third flow channel 131, and the fourth flow channel 141. An annular sealing ring 31 is embedded in the annular groove 3. The sealing ring 31 is tightly pressed between the inner circumferential wall of the rotor 2 and the outer circumferential wall of the stator 1, thereby preventing the medium in each conveying groove or each flow channel from overflowing.

[0055] In other embodiments, the groove 3 formed on the inner circumferential wall of the rotor 2 may also be provided on the outer circumferential wall of the stator 1; alternatively, a plurality of annular grooves 3 are provided on the outer circumferential wall of the stator 1 and the inner circumferential wall of the rotor 2, and the sealing ring 31 is tightly pressed between the grooves 3 of the rotor 2 and the stator 1, thereby preventing the medium in each conveying trough or each flow channel from overflowing.

[0056] In one embodiment, please refer to Figure 3 and Figure 4 The base 11 and the first fixed sleeve 12 are independent of each other, and a first thermal insulation layer 15 is provided between the base 11 and the first fixed sleeve 12, that is, the first thermal insulation layer 15 is provided at the socket position of the base 11 and the first fixed sleeve 12. The first thermal insulation layer 15 can isolate the heat of the base 11 and the first fixed sleeve 12, thereby realizing heat isolation between the first flow channel 111 and the second flow channel 121, ensuring that the temperature of the medium passing through the base 11 and the first fixed sleeve 12 hardly affects each other, thereby reducing the influence of media with different temperature requirements on passing through the stator 1, thereby facilitating improving the use effect of the medium passing through the water transport sleeve;

[0057] And / or, the first fixing sleeve 12 and the second fixing sleeve 13 are independent of each other, and a second thermal insulation layer 16 is provided at the socketing position of the first fixing sleeve 12 and the second fixing sleeve 13. The second thermal insulation layer 16 isolates the heat of the first fixing sleeve 12 from the first fixing sleeve 12, thereby achieving thermal insulation between the second flow channel 121 and the third flow channel 131. When the second flow channel 121 and the third flow channel 131 are respectively used to transport media of different temperatures, the second thermal insulation layer 16 can ensure that the media in the second flow channel 121 and the third flow channel 131 hardly affect each other.

[0058] And / or, the second fixing sleeve 13 and the third fixing sleeve 14 are independent of each other, and a third thermal insulation layer 17 is provided between the second fixing sleeve 13 and the third fixing sleeve 14. The third thermal insulation layer 17 is provided at the socket position of the second fixing sleeve 13 and the third fixing sleeve 14 to achieve heat insulation between the third flow channel 131 and the fourth flow channel 141, ensuring that the media in the third flow channel 131 and the fourth flow channel 141 have almost no mutual impact.

[0059] As described above, the provision of the first thermal insulation layer 15, the second thermal insulation layer 16, and the third thermal insulation layer 17 strengthens the thermal insulation effect between the base 11, the first fixed sleeve 12, the second fixed sleeve 13, and the third fixed sleeve 14, thereby reducing the mutual influence of the temperature of the medium passing through the flow channels in each fixed sleeve, improving the conveying effect of the water transport sleeve, and ensuring the reliability of the medium entering the mold 7 through the stator 1.

[0060] In one embodiment, please refer to Figure 3 and Figure 4 The base 11, the first fixed sleeve 12, and the second fixed sleeve 13 all have a large diameter section and a small diameter section. The large diameter section and the small diameter section of the first fixed sleeve 12 are connected, and the large diameter section and the small diameter section of the second fixed sleeve 13 are connected. The rotor 2 is simultaneously sleeved on the large diameter section of the base 11, the large diameter section of the first fixed sleeve 12, the large diameter section of the second fixed sleeve 13, and the outer circumference of the third fixed sleeve 14. The large diameter section and the small diameter section of the base 11 are formed with a first step 113, the large diameter section and the small diameter section of the first fixed sleeve 12 are formed with a second step 123, and the large diameter section and the small diameter section of the second fixed sleeve 13 are formed with a third step 133.

[0061] The small-diameter section of the base 11, the small-diameter section of the first fixing sleeve 12, the small-diameter section of the second fixing sleeve 13, and the third fixing sleeve 14 are sequentially sleeved, that is, the first fixing sleeve 12 is sleeved on the small-diameter section of the base 11, the second fixing sleeve 13 is sleeved on the small-diameter section of the first fixing sleeve 12, and the third fixing sleeve 14 is sleeved on the small-diameter section of the second fixing sleeve 13. The large-diameter section of the base 11, the large-diameter section of the first fixing sleeve 12, the large-diameter section of the second fixing sleeve 13, and the third fixing sleeve 14 are sequentially stacked, so that the end surface of the first fixing sleeve 12 abuts against the first step 113 of the base 11, the end surface of the second fixing sleeve 13 abuts against the second step 123 of the first fixing sleeve 12, and the end surface of the third fixing sleeve 14 abuts against the third step 133 of the second fixing sleeve 13.

[0062] In the above, the base 11, the first fixing sleeve 12, the second fixing sleeve 13 and the third fixing sleeve 14 are sequentially sleeved, which facilitates the independent arrangement of each fixing sleeve and simplifies the installation of the stator 1. At the same time, the relative positions of the base 11, the first fixing sleeve 12, the second fixing sleeve 13 and the third fixing sleeve 14 of the stator 1 in the circumferential direction are not fixed before they are sequentially sleeved and fixed. In other words, when different fixing sleeves are sleeved, they can be rotated circumferentially around the axis of the fixing sleeve for a certain angle before being sleeved and fixed. In this way, before the stator 1 is sleeved and fixed, the flow channels (the first flow channel 111, the second flow channel 121, The relative positions of the third flow channel 131 and the fourth flow channel 141) can be adjusted according to actual needs. Even if the base 11, the first fixing sleeve 12, the second fixing sleeve 13 and the third fixing sleeve 14 have been processed, the relative positions of the flow channels on the different fixing sleeves on the stator 1 can still be adjusted, so as to facilitate better compatibility between the internal installation space of the molding machine and the connection position of the external pipeline, reduce the requirements of the internal space of the molding machine and the external pipeline for the setting position of the stator flow channel, thereby facilitating the installation of the stator 1, and facilitating the batch production and storage of the stator 1 accessories in advance, which is beneficial to saving the production cycle of the entire molding machine.

[0063] In one embodiment, the base 11, first fixing sleeve 12, and second fixing sleeve 13 are all configured with a cylindrical large diameter section. Specifically, the large diameter sections of the base 11, the first fixing sleeve 12, and the second fixing sleeve 13 are all cylindrical. The base 11, the first fixing sleeve 12, and the second fixing sleeve 13 are all configured with a T-shaped cross-section, and the third fixing sleeve 14 is cylindrical. Consequently, the interior of the rotor 2 is also configured with a cylindrical through hole, reducing the volume of the rotor 2 formed by the sleeves being joined together. This also facilitates processing and facilitates the rotation of the rotor 2 about the sleeves. The large diameter sections of the base 11, the first fixing sleeve 12, the second fixing sleeve 13, and the third fixing sleeve 14 have the same outer diameter.

[0064] Alternatively, in another embodiment, the large diameter sections of the base 11, the first fixing sleeve 12, and the second fixing sleeve 13 are all trapezoidal cones with outer diameters gradually decreasing from one end to the other. Specifically, the large diameter section of the base 11 is a trapezoidal cone, the large diameter section of the first fixing sleeve 12 is a trapezoidal cone, and the large diameter section of the second fixing sleeve 13 is a trapezoidal cone. The small diameter sections of the base 11, the first fixing sleeve 12, and the second fixing sleeve 13 are all small cones. Through holes are provided on the axes of the trapezoidal cones and the small cones. After the base 11, the first fixing sleeve 12, and the second fixing sleeve 13 are sequentially connected, the large diameter sections are stacked to form a large trapezoidal cone. In this case, the interior of the rotor 2 is also configured with trapezoidal holes with inner diameters gradually decreasing from one end to the other. The inner circumferential wall of the rotor 2 and the outer circumferential wall of the large cone cooperate and slide with each other, allowing the rotor 2 to rotate around the four large diameter sections. In this case, the third fixing sleeve 14 is cylindrical.

[0065] In one embodiment, please refer to Figure 3 and Figure 4 The rotor 2 includes a first rotating ring 21, a second rotating ring 22, a third rotating ring 23, and a fourth rotating ring 24, which are stacked in sequence along the axial direction to facilitate installation of the rotor 2. The first rotating ring 21 is sleeved on the outside of the base 11, specifically, the first rotating ring 21 is sleeved on the large-diameter section of the base 11. A first movable interface 212 is provided on the first rotating ring 21, and a first conveying groove 211 is defined on the inner circumferential wall of the first rotating ring 21 or the outer circumferential wall of the base 11. The second rotating ring 22 is sleeved on the outside of the first fixed sleeve 12, specifically, the second rotating ring 22 is sleeved on the large-diameter section of the first fixed sleeve 12. A second movable interface 222 is provided on the second rotating ring 22, and a second conveying groove 221 is defined on the inner circumferential wall of the second rotating ring 22 or the outer circumferential wall of the first fixed sleeve 12. The third swivel 23 is sleeved on the outside of the second fixed sleeve 13. Specifically, the third swivel 23 is sleeved on the large-diameter section of the second fixed sleeve 13. A third movable interface 232 is provided on the third swivel 23. A third conveying groove 231 is defined on the inner circumferential wall of the third swivel 23 or on the outer circumferential wall of the second fixed sleeve 13. The fourth swivel 24 is sleeved on the outside of the third fixed sleeve 14 and is used to be fixed to the turntable 6. Specifically, the fourth swivel 24 is sleeved on the large-diameter section of the third fixed sleeve 14. A fourth movable interface 242 is provided on the fourth swivel 24. A fourth conveying groove 241 is defined on the inner circumferential wall of the fourth swivel 24 or on the outer circumferential wall of the third fixed sleeve 14.

[0066] A convex ring 243 is convexly provided on the fourth rotating ring 24 , and the convex ring 243 is used to form a fixed connection with the rotating disk 6 .

[0067] In one embodiment, please refer to Figure 3 and Figure 4 The first swivel 21, the second swivel 22, the third swivel 23 and the fourth swivel 24 are arranged at intervals along the axial direction. The first swivel 21 and the second swivel 22 are independent of each other, and a first thermal insulation pad 25 is provided between the first swivel 21 and the second swivel 22. The first thermal insulation pad 25 is used to isolate the first conveying trough 211 and the second conveying trough 221, ensuring that the temperatures of the media passing through the first swivel 21 and the second swivel 22 have almost no mutual influence. In this way, the influence of media with different temperature requirements on the media passing through the rotor 2 can be reduced, thereby facilitating the improvement of the use effect of the media passing through the water transport jacket.

[0068] And / or, the second swivel 22 and the third swivel 23 are independent of each other, and a second thermal insulation pad 26 is provided between the second swivel 22 and the third swivel 23. The second thermal insulation pad 26 is used to isolate the second conveying trough 221 and the third conveying trough 231, ensuring that the temperatures of the media passing through the second swivel 22 and the third swivel 23 have almost no mutual influence. This can reduce the impact on media with different temperature requirements when passing through the rotor 2, thereby facilitating the improvement of the use effect of the medium passing through the water transport jacket.

[0069] And / or, the third rotating ring 23 and the fourth rotating ring 24 are independent of each other, and a third thermal insulation pad 27 is provided between the third rotating ring 23 and the fourth rotating ring 24. The third thermal insulation pad 27 is used to isolate the third conveying trough 231 and the fourth conveying trough 241, ensuring that the temperatures of the media passing through the third rotating ring 23 and the fourth rotating ring 24 have almost no mutual influence. This can reduce the impact on media with different temperature requirements when passing through the rotor 2, thereby facilitating the improvement of the use effect of the medium passing through the water transport jacket.

[0070] Among them, the first thermal insulation pad 25 is spaced apart on the outside of the first thermal insulation layer 15, the second thermal insulation pad 26 is spaced apart on the outside of the second thermal insulation layer 16, and the third thermal insulation pad 27 is spaced apart on the outside of the third thermal insulation layer 17. The combined effect of each thermal insulation pad (i.e., the first thermal insulation pad 25, the second thermal insulation pad 26 and the third thermal insulation pad 27) and each thermal insulation layer (i.e., the first thermal insulation layer 15, the second thermal insulation layer 16 and the third thermal insulation layer 17) can further improve the thermal insulation effect of the water transport jacket, thereby facilitating the transportation of media of different temperatures.

[0071] In other embodiments, the number of rotating rings can also be set according to actual needs. The rotor 2 can be composed of more than two rotating rings. The number of rotating rings corresponds one-to-one to the number of fixed sleeves of the stator 1. Adjacent rotating rings are fixed by bonding with thermal insulation pads, or are fixed by locking with a limiting structure / limiting member to ensure that more than two rotating rings can rotate with the turntable 6 as a whole.

[0072] In other embodiments, the number of thermal insulation pads can also be set according to actual needs, and a thermal insulation pad is set between two adjacent rotating rings.

[0073] In one embodiment, when the first flow channel 111, the second flow channel 121, the third flow channel 131, or the fourth flow channel 141 is used to transport gas or oil to respectively perform pneumatic control or hydraulic control on the mold 7, pressure is usually required for inputting gas or oil. When gas or oil is transported by pressure, the water transport jacket will be affected by the pressure. Excessive or insufficient pressure will affect the use of the water transport jacket and may also cause the medium in the water transport jacket to overflow or external air to enter the water transport jacket. To this end, a booster pump is provided between at least one of the first active interface 212, the second active interface 222, the third active interface 232, and the fourth active interface 242 and the mold 7, that is, a booster pump is provided on the pipeline connecting at least one of the first active interface 212, the second active interface 222, the third active interface 232, and the fourth active interface 242 and the mold 7; and a throttle valve is provided between at least one of the first active interface 212, the second active interface 222, the third active interface 232, and the fourth active interface 242 and the mold 7, that is, a throttle valve is provided on the pipeline connecting at least one of the first active interface 212, the second active interface 222, the third active interface 232, and the fourth active interface 242 and the mold 7. The booster pump can be replaced by a pressure pump or other device for boosting pressure, which can pressurize the gas or oil when it enters the mold 7; the throttle valve can be replaced by a flow limiting valve or other device for limiting pressure and flow, which can limit the pressure and flow of the gas or oil output from the mold 7. The pneumatic and hydraulic components are controlled by controlling the booster pump to pressurize its gas or oil. At the same time, the output gas or oil can be limited in pressure and flow through the throttle valve, thereby ensuring that the air pressure or oil pressure in the mold 7 meets the normal working requirements of the pneumatic and hydraulic components, and at the same time ensuring the normal pressure in the water transport jacket to avoid overflow or infiltration, thereby ensuring the smooth and normal operation of the molding machine.

[0074] In one embodiment, please refer to Figure 2 and Figure 5The water transport jacket also includes a joint structure 4, which comprises a fixed portion 41 secured to the base 11 and a rotating portion 42 secured to the rotor 2. The rotating portion 42 is sleeved around the fixed portion 41 and rotatable about it. A first conductive beam 5 is connected to the fixed portion 41, extending from one axial end of the base 11 and electrically connected to an external power supply. A second conductive beam is connected to the rotating portion 42, which is used to establish an electrical connection with electrical components within the mold 7. As the rotor 2 rotates about the stator 1, the rotating portion 42 rotates about the fixed portion 41. At this time, the second conductive beam rotates simultaneously with the rotating portion 42 and establishes real-time electrical connection with the first conductive beam 5. Furthermore, the second conductive beam is used to electrically connect to electrical components within the mold 7. These components can be configured as at least one of an electric heater, a solenoid valve, and a sensor. The real-time electrical connection between the first conductive beam 5 and the second conductive beam allows electrical connection to be established within the mold 7, if such components are present.

[0075] In one embodiment, please refer to Figure 2 and Figure 5 The fixed portion 41 is provided with a plurality of conductive brushes 411, which are connected to the first conductive bundle 5. The first conductive bundle 5 passes through the base 11 and out of one end of the base 11 to connect to an external power supply device. The rotating portion 42 is provided with a plurality of metal rings 421, which are connected to the second conductive bundle. When the turntable 6 rotates, the rotor 2 rotates around the stator 1. At this time, the rotating portion 42 rotates around the rotating portion 42 along with the rotor 2. At this time, the plurality of metal rings 421 rotate around the plurality of conductive brushes 411 respectively. When the rotating portion 42 rotates around the fixed portion 41, the plurality of conductive metal rings 421 contact and conduct with the plurality of conductive brushes 411 in a one-to-one correspondence. As a result, the plurality of metal rings 421 are respectively connected to the plurality of conductive brushes 411 in real time, facilitating the electrical components in the mold 7 to be connected to the external power supply device. This facilitates the electrical components in the mold 7 to operate in real time when the multi-station molding machine is operating, thereby facilitating continuous and rapid production and ensuring smooth production.

[0076] The present application also provides a forming machine, including a water transport jacket. The water transport jacket adopts the water transport jacket described in the above embodiment. The above embodiment has explained it in detail, and will not be repeated here one by one.

[0077] The molding machine provided in the present application is configured so that when the rotor 2 rotates around the stator 1, the external pipes connected to the first flow channel 111 and the second flow channel 121 can communicate with the mold 7, thereby ensuring the medium transportation between the external pipes and the mold 7, and facilitating the transportation of the corresponding medium into the mold 7 when the molding machine is working. The first fixed sleeve 12 is axially sleeved on the outer peripheral wall of the base 11, so that the base 11 and the first fixed sleeve 12 are independent of each other, and the first flow channel 111 and the second flow channel 121 are also independent of each other, which can ensure that the temperatures of the media passing through the first flow channel 111 and the second flow channel 121 have almost no mutual influence, reducing the impact on media with different temperature requirements when passing through the stator 1, thereby improving the use effect of the medium passing through the water transport sleeve and meeting the requirements of the corresponding process;

[0078] At the same time, the relative positions of the base 11, the first fixing sleeve 12, the second fixing sleeve 13 and the third fixing sleeve 14 of the stator 1 in the circumferential direction are not fixed before they are successively sleeved and fixed, or in other words, when different fixing sleeves are sleeved, they can be rotated circumferentially around the axis of the fixing sleeve for a certain angle before being sleeved and fixed. In this way, before the stator 1 is sleeved and fixed, the relative positions of the flow channels (the first flow channel 111, the second flow channel 121, the third flow channel 131 and the fourth flow channel 141) between the fixing sleeves thereon can be adjusted according to actual needs. Even if the base 11, the first fixing sleeve 12, the second fixing sleeve 13 and the third fixing sleeve 14 have been processed, the relative positions of the flow channels on the different fixing sleeves on the stator 1 can still be adjusted, so as to facilitate better compatibility between the internal installation space of the molding machine and the connection position of the external pipeline, reduce the requirements of the internal space of the molding machine and the external pipeline for the setting position of the stator flow channel, thereby facilitating the installation of the stator 1, and facilitating the batch production and storage of the stator 1 accessories in advance, which is beneficial to saving the production cycle of the entire molding machine.

[0079] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
