Description

Technical Field

[0001] This utility model relates to the field of rubber manufacturing technology, specifically to a mold for a rubber impeller stator. Background Technology

[0002] In the rubber manufacturing process, the rubber impeller stator is a key component, and its manufacturing precision and quality have a significant impact on the performance of the final product. Traditional rubber impeller stator molds suffer from insufficient precision and poor cushioning during the molding process, resulting in unstable dimensions, poor surface quality, and even the possibility of producing defective rubber impeller stators.

[0003] According to the published injection mold for producing impellers (publication number: CN106863712B): it includes a mold frame, on which an upper mold and a lower mold are fitted together, and a guide post is provided on the mold frame that passes through the upper mold and the lower mold. A first mold cavity for processing the top cover of the impeller is provided on the mating surface of the upper mold and the lower mold. A fixing post is fixedly provided inside the mold frame. The top of the fixing post contacts the side of the lower mold away from the upper mold, and a second mold cavity for processing the impeller body is provided on the contact surface. An upper auxiliary plate is provided on the side of the upper mold away from the lower mold. A gate for plastic to enter is provided on the upper auxiliary plate. A first runner is provided inside the upper mold that connects the gate and the first mold cavity. A second runner is provided on the lower mold that connects the first runner and the second mold cavity.

[0004] In the aforementioned application, the combination of the upper sub-plate, gate, first runner, and second runner facilitates the injection and molding of plastic to a certain extent. However, the accuracy and buffering effect of the molding process still need to be improved, especially in the manufacturing of products such as rubber impeller stators that have high requirements for dimensional accuracy and surface quality. Therefore, we propose a mold specifically for rubber impeller stators. Utility Model Content

[0005] To overcome the above-mentioned defects, this utility model provides a special mold for rubber impeller stators, which solves the technical problems of poor accuracy and insufficient buffering in the existing mold during molding.

[0006] According to one aspect, at least one embodiment of the present invention provides a mold for a rubber impeller stator, comprising: a processing table, a control panel on the top of the processing table, a lower mold on the top of the processing table, and a pressing device on the top of the processing table.

[0007] The pressing device includes a main support plate, which is fixedly connected to the top of the processing table. A main board is slidably connected through the side of the main support plate. A mounting plate is fixedly connected to the side of the main board. A connecting block is fixedly connected to the side of the mounting plate. A connecting column is fixedly connected to the bottom of the connecting block. A limit block is fixedly connected to the end of the connecting column away from the connecting block. A buffer spring is fixedly connected to the bottom of the connecting block. An upper mold is slidably connected through the circumference of the connecting column. A feeding pipe is fixedly connected to the side of the upper mold. A connecting plate is fixedly connected to the top of the mounting plate. A threaded sleeve is slidably connected through the bottom of the connecting plate. A fixing plate is fixedly connected to the top of the processing table. A motor is fixedly connected to the side of the fixing plate. A threaded rod is fixedly connected to the output shaft of the motor.

[0008] For example, in at least one embodiment of the present invention, a special mold for a rubber impeller stator is provided, which further includes a buffer pad. The bottom of the mounting plate is fixedly connected to the buffer pad, and the bottom of the buffer pad is located on the displacement trajectory of the top of the upper mold. Its function is to buffer and protect the upper mold during the pressing process of the upper mold, avoid rigid collision between the upper mold and the mounting plate, and thus improve the service life of the mold.

[0009] The end of the buffer spring away from the connecting block is fixedly connected to the top of the upper mold. The bottom of the limiting block is located on the displacement trajectory of the bottom of the upper mold. Its function is to limit the upper mold during the pressing process to prevent the upper mold from pressing down too much and damaging the lower mold.

[0010] The circumferential surface of the threaded rod is threadedly connected to the inner wall of the threaded sleeve. The top of the lower mold is located on the displacement trajectory of the bottom of the upper mold. Its function is that the rotation of the threaded rod will drive the threaded sleeve and the connecting plate, mounting plate and other components fixedly connected to it to move up and down.

[0011] Two fixed plates are provided, symmetrically distributed along the vertical central axis of the processing table. Two buffer springs and mounting plates are provided, symmetrically distributed along the vertical central axis of the upper mold. Their function is to improve the stability of the mold during operation, ensure that the upper mold can press down smoothly and accurately align with the lower mold, thereby improving the molding quality and production efficiency of the product.

[0012] The connecting plate has an L-shaped side section, and the lower mold is located directly below the upper mold. Its function is to facilitate the connection between the connecting plate and the motor and other components on the fixed plate, while ensuring that the upper mold can be vertically aligned with the lower mold for pressing operation, thereby improving the accuracy and efficiency of the mold.

[0013] According to another aspect, at least one embodiment of this utility model also provides a mold specifically for rubber impeller stators, comprising: a heat dissipation device, wherein the heat dissipation device is provided on the top of the processing table, the heat dissipation device includes a water pump, the water pump is fixedly connected to the top of the processing table, a pulley one is fixedly connected to the input shaft of the water pump, a pulley two is fixedly connected to the circumferential surface of the threaded rod, a belt is provided on the circumferential surface of the pulley two, the pulley one and the pulley two are connected by belt drive, a water tank is fixedly connected to the side of the processing table, and a heat dissipation pipe is fixedly connected to the top of the water tank. The function of the water pump is to draw coolant from the water tank and circulate it through the heat dissipation pipe for heat dissipation. When the coolant flows within the heat dissipation pipe, it can absorb heat from the mold and the surrounding environment, thereby reducing the mold temperature.

[0014] For example, in at least one embodiment of the present invention, a mold for a rubber impeller stator is provided, which further includes: a water inlet pipe, the top of the water tank is fixedly connected to the water inlet pipe, a water valve is provided on the circumferential surface of the heat dissipation pipe, and a support plate is fixedly connected to the circumferential surface of the heat dissipation pipe. The function of the water inlet pipe is to facilitate the addition of coolant to the water tank, the water valve is provided to facilitate the control of coolant circulation, and the support plate provides support and fixation for the heat dissipation pipe to ensure the stable operation of the heat dissipation pipe.

[0015] The heat dissipation pipe has an S-shaped side cross-section and abuts against the side of the lower mold. The S-shape increases the flow path of the coolant, thereby improving heat dissipation efficiency. As the coolant flows within the heat dissipation pipe, it effectively absorbs and carries away the heat from the lower mold, thus achieving rapid cooling of the mold.

[0016] The bottom of the support plate is fixedly connected to the top of the processing table, and the inside of the water inlet pipe runs through the inside of the water tank. Its function is to ensure that the water inlet pipe can smoothly inject coolant into the water tank. At the same time, the stable fixation of the support plate further ensures the stable operation of the heat dissipation pipe during the heat dissipation process.

[0017] The beneficial effects of the embodiments of this utility model are as follows: 1. In this utility model, the smooth lifting and lowering of the upper mold is achieved through the cooperation of components such as the main support plate, main board, and mounting plate in the pressing device, thereby ensuring the precise positioning and pressing of the rubber impeller stator within the mold. Simultaneously, the inclusion of buffer springs and buffer pads effectively reduces the impact force during the pressing of the upper mold, protecting the mold structure and extending its service life. Furthermore, the cooperation between the threaded rod and threaded sleeve allows the pressing device to precisely control the pressing height of the upper mold, further improving the molding accuracy of the product.

[0018] 2. In this invention, the coordinated operation of components such as the water pump, pulley one, and pulley two in the heat dissipation device achieves the circulation and heat dissipation of the coolant, thereby effectively reducing the temperature of the mold during operation and ensuring the molding quality of the rubber impeller stator. Simultaneously, the S-shaped heat dissipation pipe design not only improves heat dissipation efficiency but also ensures that the coolant can fully absorb and remove heat from the mold, achieving rapid cooling. Furthermore, the inclusion of a water inlet pipe and water valve facilitates the addition and circulation control of the coolant, further enhancing the mold's heat dissipation effect and operational stability.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit its scope.

[0027] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0028] like Figures 1-5 As shown, it illustrates a mold for a rubber impeller stator according to an embodiment of the present invention, including a processing table 1, a control panel 2 on the top of the processing table 1, a lower mold 3 on the top of the processing table 1, and a pressing device 4 on the top of the processing table 1.

[0029] The pressing device 4 includes a main support plate 401, which is fixedly connected to the top of the processing table 1. A main board 402 is slidably connected through the side of the main support plate 401. A mounting plate 403 is fixedly connected to the side of the main board 402. A connecting block 404 is fixedly connected to the side of the mounting plate 403. A connecting column 405 is fixedly connected to the bottom of the connecting block 404. A limit block 406 is fixedly connected to the end of the connecting column 405 away from the connecting block 404. A buffer spring 407 is fixedly connected to the bottom of the connecting block 404. An upper mold 408 is slidably connected through the circumferential surface of the connecting column 405. A feeding pipe 409 is fixedly connected to the side of the upper mold 408. A connecting plate 410 is fixedly connected to the top of the mounting plate 403. A threaded sleeve 411 is slidably connected through the bottom of the connecting plate 410. A fixing plate 412 is fixedly connected to the top of the processing table 1. A motor 413 is fixedly connected to the side of the fixing plate 412. A threaded rod 414 is fixedly connected to the output shaft of the motor 413.

[0030] In some examples, a buffer pad 5 is fixedly connected to the bottom of the mounting plate 403. The bottom of the buffer pad 5 is located on the displacement trajectory of the top of the upper mold 408. Its function is to buffer and protect the upper mold 408 during the pressing process, so as to avoid rigid collision between the upper mold 408 and the mounting plate 403, thereby improving the service life of the mold.

[0031] The end of the buffer spring 407 away from the connecting block 404 is fixedly connected to the top of the upper mold 408. The bottom of the limiting block 406 is located on the displacement trajectory of the bottom of the upper mold 408. Its function is to limit the upper mold 408 during the pressing process to prevent the upper mold 408 from being pressed down too much and damaging the lower mold 3.

[0032] The circumferential surface of the threaded rod 414 is threadedly connected to the inner wall of the threaded sleeve 411. The top of the lower mold 3 is located on the displacement trajectory of the bottom of the upper mold 408. Its function is that the rotation of the threaded rod 414 will drive the threaded sleeve 411 and the connecting plate 410, mounting plate 403 and other components fixedly connected to it to move up and down.

[0033] There are two fixed plates 412, which are symmetrically distributed along the vertical central axis of the processing table 1. There are two buffer springs 407 and two mounting plates 403, which are symmetrical along the vertical central axis of the upper mold 408. Their function is to improve the stability of the mold during operation, ensure that the upper mold 408 can be pressed down smoothly and accurately aligned with the lower mold 3, thereby improving the molding quality and production efficiency of the product.

[0034] The side section of the connecting plate 410 is set to L-shape, and the lower mold 3 is located directly below the upper mold 408. Its function is to facilitate the connection between the connecting plate 410 and components such as the motor 413 on the fixing plate 412, and at the same time ensure that the upper mold 408 can be vertically aligned with the lower mold 3 for pressing operation, thereby improving the accuracy of the mold and the working efficiency.

[0035] For example, such as Figures 1-5 As shown, when the operator starts the motor 413 via the control panel 2, the output shaft of the motor 413 drives the threaded rod 414 to rotate. Since the circumferential surface of the threaded rod 414 is threadedly connected to the inner wall of the threaded sleeve 411, the rotation of the threaded rod 414 drives the threaded sleeve 411 and its fixedly connected components such as the connecting plate 410 and mounting plate 403 to move up and down. During this process, the mounting plate 403 drives the upper mold 408 to move downwards until the upper mold 408 is in close contact with the lower mold 3, completing the forming operation of the rubber impeller stator. The buffer spring 407 and the buffer pad 5 play an important role in buffering and protecting the upper mold 408 during its downward pressing. The buffer spring 407 absorbs the impact force when the upper mold 408 is pressed down, preventing rigid collisions between the upper mold 408 and the mounting plate 403, thereby improving the service life of the mold. The buffer pad 5 further enhances the buffering effect, ensuring that the upper mold 408 can be pressed down smoothly and accurately aligned with the lower mold 3.

[0036] like Figures 1-5 As shown, this invention illustrates a mold for a rubber impeller stator according to another embodiment of the present invention. The mold includes a heat dissipation device 6. The heat dissipation device 6 is mounted on the top of the processing table 1. The heat dissipation device 6 includes a water pump 601, which is fixedly connected to the top of the processing table 1. A pulley 602 is fixedly connected to the input shaft of the water pump 601. A pulley 603 is fixedly connected to the circumferential surface of the threaded rod 414. A belt 604 is mounted on the circumferential surface of the pulley 603. The pulley 602 and pulley 603 are connected by the belt 604. A water tank 605 is fixedly connected to the side of the processing table 1. A heat dissipation pipe 606 is fixedly connected to the top of the water tank 605. The function of the water pump 601 is to draw coolant from the water tank 605 and circulate it through the heat dissipation pipe 606 for heat dissipation. When the coolant flows within the heat dissipation pipe 606, it absorbs heat from the mold 3 and the surrounding environment, thereby reducing the mold temperature.

[0037] In some examples, a water inlet pipe 7 is fixedly connected to the top of the water tank 605, a water valve 8 is provided on the circumferential surface of the heat dissipation pipe 606, and a support plate 9 is fixedly connected to the circumferential surface of the heat dissipation pipe 606. The function of the support plate 9 is to facilitate the addition of coolant to the water tank 605 by the water inlet pipe 7, to facilitate the control of coolant circulation by the water valve 8, and to support and fix the heat dissipation pipe 606 to ensure the stable operation of the heat dissipation pipe 606.

[0038] The heat dissipation pipe 606 has an S-shaped side section. The heat dissipation pipe 606 abuts against the side of the lower mold 3. Its function is to increase the flow path of the coolant, thereby improving the heat dissipation efficiency. When the coolant flows in the heat dissipation pipe 606, it can fully absorb the heat of the lower mold 3 and carry the heat away, thereby achieving rapid cooling of the mold.

[0039] The bottom of the support plate 9 is fixedly connected to the top of the processing table 1. The inside of the water inlet pipe 7 runs through the inside of the water tank 605. Its function is to ensure that the water inlet pipe 7 can smoothly inject coolant into the water tank 605. At the same time, the stable fixation of the support plate 9 further ensures the stable operation of the heat dissipation pipe 606 during the heat dissipation process.

[0040] For example, such as 1~ Figure 5 As shown, when the motor 413 drives the threaded rod 414 to rotate, the pulley 603 will rotate accordingly due to the fixed connection between the pulley 603 and the threaded rod 414. Through the transmission connection of the belt 604, the pulley 602 will rotate synchronously, thereby driving the water pump 601 to work. The water pump 601 draws coolant from the water tank 605 and circulates it through the heat dissipation pipe 606. The heat dissipation pipe 606 is S-shaped, increasing the flow path of the coolant and improving heat dissipation efficiency. When the coolant flows within the heat dissipation pipe 606, it can fully absorb the heat from the lower mold 3, achieving rapid cooling of the mold. Simultaneously, the water valve 8 allows operators to control the circulation of coolant to adapt to different heat dissipation needs.

[0041] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
