[0002] The sealing ring is a key component for controlling fluid or gas leakage and is widely used in machinery, automobiles, chemicals and other fields. It has good sealing performance, stable friction coefficient, corrosion resistance and wear resistance, simple structure, easy use, maintenance and replacement, and can ensure the reliability and performance of the equipment. When the sealing ring is processed and molded, an injection molding embedded full hot runner sealing ring mold is required.

[0003] When using the existing injection molding embedded full hot runner sealing ring mold, the raw materials (melted rubber or plastic) for processing the sealing ring need to be poured into the mold. When adding the raw materials, the existing sealing ring mold mostly uses a nozzle to add the raw materials into the mold cavity. When using the nozzle to add the raw materials, the raw material output is not uniform enough, and the raw materials in the sealing ring mold cavity are not flat. At the same time, it is not convenient to clean out the excess raw materials on the mold, resulting in the raw materials in the mold cavity are not neat and flat, which in turn affects the quality of the injection molding embedded full hot runner sealing ring finished product. For this reason, we propose an injection molding embedded full hot runner sealing ring mold and a method for using it. Summary of the invention

[0011] Preferably, the feeding unit includes a delivery pump, which is located on the rear outer wall of the storage box, and the feed port of the delivery pump is connected to a feed pipe, the bottom end of the feed pipe is connected to the inner cavity of the storage box, the discharge port of the delivery pump is installed with a discharge hose, and the bottom end of the discharge hose is connected to the inner cavity of the discharge tray, and the top of the storage box is provided with a feeding pipe for connection.

[0012] Preferably, the cleaning assembly includes a reduction motor, which is located on the rear outer wall of the lower mold. A cavity is opened on the left side of the inner cavity of the lower mold. The output end of the reduction motor is connected to a screw, and the bottom end of the screw is rotatably connected to the inner wall of the cavity through a bearing. A threaded block is threadedly connected to the screw. A through hole connecting to the cavity is opened on the left side wall of the feed chute, and a connecting slider is slidably connected in the through hole, and the two ends of the connecting slider are respectively connected to the threaded block and the feed plate.

[0015] Preferably, a sealing cap is threadedly connected to the feeding tube, a filter screen is installed on the inner wall of the feeding tube, and the filter screen is movably connected to the inner wall of the feeding tube by means of a snap connection.

[0016] S1: First, fit the workbench onto the work surface, and install the sealing ring mold at the working position with the help of four sets of bolts vertically connected to the threaded mounting holes in the four sets of ear plates. Then, add the melted rubber or plastic for processing the sealing ring into the storage box through the feeding pipe. Then, the controller controls the two sets of electric push rods to work synchronously, so that the upper mold descends and fits onto the upper surface of the lower mold. At this time, the smoothing plates and scraping push plates at both ends are located at both ends of the upper mold.

[0017] S2: The controller controls the servo motor to work, and the work of the servo motor drives the rotating gear on the rotating shaft to rotate. Since the rotating gear is meshed and connected with the lifting gear plate, the lifting gear plate drives the discharge tray to move downward, so that the multiple groups of connected discharge covers at the bottom of the discharge tray are attached to the upper surface of the lower mold, and then the conveying pump is started. The work of the conveying pump makes the feed pipe generate suction, and the melted rubber or plastic in the storage box is conveyed to the discharge tray through the discharge hose.

After the conveying is completed, the servo motor reverses, the conveying pump stops working, and the discharge tray moves up to the upper part of the inner cavity of the upper mold;

[0018] S3: The controller is used to control the stepper motor to work. The stepper motor can drive the bidirectional screw to rotate. After the two sets of threaded seats connected to the bidirectional screw thread are limited by the sliding of the fixed rod and the slide seat, the slide seat slides in the through groove. The two sets of slide seats drive the two sets of smoothing plates and scraper push plates to move in relative directions through the fixed parts. The scraper push plates scrape off the excess melted rubber or plastic on the lower mold and push it into the discharge trough. The two sets of smoothing plates are attached to the top wall of the lower mold.

[0019] S4: After the melted rubber or plastic in the cavity of the multiple sealing rings on the lower mold is cooled and formed, the controller controls the two sets of electric push rods to work synchronously to move the upper mold upward and separate from the lower mold, so that the sealing rings with full hot runners embedded in the injection molding can be taken out;

[0020] S5: When it is necessary to clean the excess melted rubber or plastic in the feed chute, the controller controls the reduction motor on the cleaning component. The reduction motor can drive the screw to rotate. After the threaded block connected to the screw thread passes through the through-port and the sliding limit of the connecting slider, the feed plate can be driven to move back and forth on the inner wall of the feed chute, so as to quickly clean the melted rubber or plastic in the feed chute.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. The present invention works by means of a servo motor, which can drive the rotating gear on the rotating shaft to rotate. Since the rotating gear is meshed and connected with the lifting tooth plate, the lifting tooth plate drives the unloading tray to move downward, so that multiple groups of connected unloading covers at the bottom of the unloading tray are attached to the upper surface of the lower mold. The melted rubber or plastic in the storage box is transported to the unloading tray through the unloading hose through the feeding unit, and the melted rubber or plastic is evenly transported to the sealing ring mold cavity by multiple groups of unloading through holes, so that the raw materials for processing the sealing ring are evenly fed. The operation of the machine can drive the bidirectional screw to rotate. After the two sets of threaded seats connected with the bidirectional screw threads pass through the sliding limit of the fixed rod and the slide seat, the slide seat slides in the through groove. The two sets of slide seats drive the two sets of caressing plates and scraper push plates to move in relative directions through the fixed parts. The scraper push plate scrapes off the excess melted rubber or plastic on the lower mold and pushes it into the unloading trough, ensuring the cleanliness of the raw materials on the processed sealing ring. The caressing plate blocks the raw materials in the sealing ring cavity, improving the quality of the finished product of the injection molding embedded full hot runner sealing ring;

[0023] 2. The work of the reduction motor on the cleaning component can drive the screw to rotate. After the threaded block connected to the screw thread passes through the sliding limit of the through-port and the connecting slider, the unloading plate can be driven to move back and forth on the inner wall of the unloading trough, which can quickly clean the excess melted rubber or plastic in the unloading trough and can be recycled for a second time, saving costs and eliminating the need for manual cleaning, thereby improving work efficiency.

[0048] An injection molding mold with a fully hot runner seal ring and a method of using the mold include the following steps:

[0049] S1: First, the workbench 1 is attached to the workbench surface, and the sealing ring mold is installed in the working position by means of four sets of bolts and vertically connected to the threaded mounting holes 3 in the four sets of ear plates 2. The electrical ends of each electrical device are electrically connected to the external power supply and the electrical ends of the controller 8, and then the melted rubber or plastic for processing the sealing ring is added to the storage box 14 through the feeding pipe 15. Then, the controller 8 controls the two sets of electric push rods 7 to work synchronously, so that the upper mold 5 is lowered and attached to the upper surface of the lower mold 4. At this time, the smoothing plate 901 and the scraping push plate 902 at both ends are located at both ends of the upper mold 5;

[0050] S2: The controller 8 controls the servo motor 17 to work, and the work of the servo motor 17 drives the rotating gear 25 on the rotating shaft to rotate. Since the rotating gear 25 is meshed and connected with the lifting gear plate 18, the lifting gear plate 18 drives the unloading tray 22 to move downward, so that the multiple groups of connected unloading covers 23 at the bottom of the unloading tray 22 are attached to the upper surface of the lower mold 4, and then the delivery pump 19 is started. The work of the delivery pump 19 makes the feed pipe 21 generate suction, and the melted rubber or plastic in the storage box 14 is delivered to the unloading tray 22 through the discharge hose 20. The multiple groups of discharge through holes 24 evenly deliver the melted rubber or plastic to the sealing ring mold cavity 11, ensuring the uniformity of the raw material feeding. After the delivery is completed, the servo motor 17 reverses, the delivery pump 19 stops working, and the unloading tray 22 moves up to the upper part of the inner cavity of the upper mold 5;

[0051] S3: The controller 8 is used to control the stepper motor 903 to work. The work of the stepper motor 903 can drive the bidirectional screw 904 to rotate. After the two groups of threaded seats 905 threadedly connected to the bidirectional screw 904 are limited by the sliding of the fixed rod 906 and the slide 907, the slide 907 slides in the through groove 908. The two groups of slides 907 drive the two groups of smoothing plates 901 and the scraping and pushing plates 902 to move in relative directions through the fixing parts 909. The scraping and pushing plates 902 scrape off the excess melted rubber or plastic on the lower mold 4 and push it into the discharge trough 12. The two groups of smoothing plates 901 are attached to the top wall of the lower mold 4 to ensure the cleanliness of the raw materials on the processed sealing ring. The smoothing plates 901 shield the raw materials in the multiple groups of sealing ring cavities 11, thereby improving the quality of the finished products of the injection molded embedded full hot runner sealing rings.

[0052] S4: After the melted rubber or plastic in the multiple sealing ring cavities 11 on the lower mold 4 is cooled and formed, the controller 8 controls the two sets of electric push rods 7 to work synchronously to move the upper mold 5 upward and separate from the lower mold 4, so that the injection molded sealing ring with embedded full hot runner can be taken out;

[0053] S5: When it is necessary to clean the excess melted rubber or plastic in the discharge chute 12, the controller 8 controls the reduction motor 131 on the cleaning component 13. The operation of the reduction motor 131 can drive the screw 132 to rotate. After the threaded block 133 threadedly connected to the screw 132 passes through the through-port 134 and the sliding limit of the connecting slider 135, the discharge plate 136 can be driven to move back and forth on the inner wall of the discharge chute 12, so that the melted rubber or plastic in the discharge chute 12 can be quickly cleaned.

[0054] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.

6. The method for using the injection molding mold with embedded full hot runner sealing ring according to claim 5, characterized in that: The method comprises the following steps: S1: First, the workbench (1) is fitted on the workbench surface, and the sealing ring mold is installed in the working position by means of four sets of bolts and vertically connected to the threaded mounting holes (3) in the four sets of ear plates (2). Then, the melted rubber or plastic for processing the sealing ring is added into the storage box (14) through the feeding pipe (15). Then, the controller (8) controls the two sets of electric push rods (7) to work synchronously, so that the upper mold (5) is lowered and fitted on the upper surface of the lower mold (4). At this time, the smoothing plates (901) and the scraping push plates (902) at both ends are located at both ends of the upper mold (5); S2: The controller (8) controls the servo motor (17) to operate. The operation of the servo motor (17) drives the rotating gear (25) on the rotating shaft to rotate. Since the rotating gear (25) is meshed and connected with the lifting gear plate (18), the lifting gear plate (18) drives the unloading tray (22) to move downward, so that the multiple groups of interconnected unloading covers (23) at the bottom of the unloading tray (22) are attached to the upper surface of the lower mold (4). Then, the delivery pump (19) is started. The operation of the delivery pump (19) causes the feed pipe (21) to generate suction, and the melted rubber or plastic in the storage box (14) is transported to the unloading tray (22) through the discharge hose (20). The multiple groups of discharge through holes (24) evenly transport the melted rubber or plastic to the sealing ring mold cavity (11). After the transportation is completed, the servo motor (17) is reversed, the delivery pump (19) stops working, and the unloading tray (22) moves upward to the upper part of the inner cavity of the upper mold (5); S3: The stepper motor (903) is controlled to work by the controller (8). The work of the stepper motor (903) can drive the bidirectional screw (904) to rotate. After the two sets of threaded seats (905) threadedly connected to the bidirectional screw (904) are limited by the sliding of the fixed rod (906) and the slide seat (907), the slide seat (907) slides in the through groove (908). The two sets of slide seats (907) drive the two sets of smoothing plates (901) and the scraping and pushing plates (902) to move in relative directions through the fixing member (909). The scraping and pushing plates (902) scrape off the excess melted rubber or plastic on the lower mold (4) and push it into the lower material trough (12). The two sets of smoothing plates (901) are attached to the top wall of the lower mold (4); S4: After the melted rubber or plastic in the multiple sealing ring cavities (11) on the lower mold (4) is cooled and formed, the controller (8) controls the two sets of electric push rods (7) to work synchronously so that the upper mold (5) moves upward and separates from the lower mold (4), so that the sealing ring with the full hot runner embedded in the injection molding can be taken out; S5: When it is necessary to clean the excess melted rubber or plastic in the feed chute (12), the controller (8) controls the reduction motor (131) on the cleaning component (13). The reduction motor (131) can drive the screw (132) to rotate. After the threaded block (133) threadedly connected to the screw (132) passes through the through opening (134) and the sliding limit of the connecting slider (135), the feed plate (136) can be driven to move back and forth on the inner wall of the feed chute (12), so that the melted rubber or plastic in the feed chute (12) can be quickly cleaned.
