Liquid silicone injection machine and method of use

Abstract

This invention relates to the field of glue dispensing pump technology, and discloses a liquid silicone injection molding machine and its usage method. The injection molding machine includes a base, lifting rod, hydraulic rod, pressure plate, connecting pipe, three-way valve, and agitation section, cleaning section, and extrusion spraying section. The agitation section automatically starts an electric rod by pushing a trigger switch downwards via a T-ring, which drives the motor and agitator to extend into the glue tank. The agitator and glue disc rotate and stir the liquid silicone, preventing layering and localized solidification. The cleaning section is quickly installed by inserting a rod into a support rod. Rotating the T-ring drives a rotating sleeve to rotate around the flange, and a cotton brush and scraper clean the pressure plate and flange. The extrusion spraying section uses a corrugated bladder to spray the solvent through guide channels and liquid channels onto the cleaning surface, combined with mechanical scraping for synergistic cleaning. This invention improves cleaning efficiency, reduces residual silicone rate, shortens equipment maintenance time, and significantly improves injection quality and production efficiency.

Description

Technical Field

[0001] This invention relates to the field of glue pump technology, specifically to a liquid silicone injection machine and its usage method. Background Technology

[0002] A liquid silicone injection molding machine is a specialized device used to extrude and transport liquid silicone from a barrel to molding equipment. Traditional liquid silicone injection molding machines typically use a pressure plate to extrude the liquid silicone from the barrel into the injection line. However, there are still problems that urgently need to be solved in actual production processes.

[0003] Conventional liquid silicone injection molding machines lack the function of stirring the silicone in the barrel during injection, resulting in stratification, sedimentation, or localized solidification of the liquid silicone during stagnant operation. Uneven component ratios affect product quality. At the same time, residual silicone on the pressure plate and flange requires manual cleaning, which is time-consuming, labor-intensive, and incomplete. After the residual silicone solidifies, it affects the sealing performance and injection stability. Existing simple scrapers have problems such as interfering with the movement of the pressure plate and poor cleaning effect, which seriously affect injection quality, equipment maintenance efficiency, and production continuity. Summary of the Invention

[0004] This invention provides a liquid silicone injection machine and its usage method, which integrates stirring and automatic cleaning functions. Before injection, the silicone in the rubber tank is automatically stirred to ensure uniformity, and after injection, the pressure plate and flange are automatically and efficiently cleaned, reducing manual intervention and improving injection quality and equipment maintenance efficiency.

[0005] To solve the above-mentioned technical problems, the technical solution of the present invention is as follows:

[0017] The motor is fixed to the telescopic end of the electric rod and located inside the sleeve.

[0018] The heat dissipation vent is cut through the sleeve and pressure plate;

[0019] The mixing components are located below the motor and are sealed through the pressure plate.

[0020] Furthermore, the mixing component includes:

[0021] The shaft is movably mounted through the lower end of the sleeve and is connected to the drive end of the motor;

[0024] The stirring plates are symmetrically fixed on the outside of the shaft and located inside the groove;

[0025] The rubber disc is fixed to the lower end of the stirring plate and is sealed to the pressure plate in the groove.

[0026] Furthermore, the connecting element includes:

[0027] The swivel sleeve is rotatably connected to the outside of the flange via a bearing;

[0028] Guide grooves are symmetrically formed on the outer side of the sleeve;

[0029] The T-ring is located on the outside of the sleeve and is guided and connected to the guide groove for vertical movement;

[0030] The support rod is connected to the outside of the support plate.

[0031] Furthermore, the scraping element includes:

[0032] The socket is located at the end of the support rod;

[0033] The insertion rod has one end inserted into the inside of the socket;

[0034] The arc plate is fitted onto the outside of the pressure plate and connected to the other end of the insertion rod;

[0035] An angled plate is attached to the end of an arc plate by a fixing component and extends to the inside of the flange.

[0036] The cotton brush is fixed to the side of the arc plate and the curved plate near the pressure plate;

[0037] The scraper is fixed to the side of the arc plate and curved plate near the pressure plate and is adjacent to the cotton brush.

[0038] Furthermore, the adjusting component includes:

[0039] A through groove is created, penetrating one side and the front of the T-ring;

[0040] Push plate, with a through-slot front panel;

[0041] The pressure plate is located inside the through groove and is connected to the push plate;

[0042] The bolts are threaded through the T-ring and extend into the inside of the groove.

[0043] A rubber pad is fixed to the lower end of the bolt to compress and fix the push plate.

[0044] Furthermore, the storage and supply component includes:

[0045] The corrugated bag is fixed to the support plate;

[0046] A one-way valve is installed through the lower end of the bellows.

[0047] A threaded cap, with threads extending through the upper end of the bellows.

[0048] Furthermore, the spray guide includes:

[0049] The support rod has a through-hole guide channel, which is connected to a one-way valve;

[0050] The first connector is fixed to one end of the insertion rod and is inserted into the guide channel;

[0051] Liquid channels are located inside the arc plates and bend plates;

[0052] Perforations are made on the side of the curved plate and bent plate near the pressure plate;

[0053] The bent plate is connected to the arc plate via a second joint.

[0054] Secondly, a method of using a liquid silicone injection molding machine includes:

[0055] The container of liquid silicone is brought into contact with the roller. The roller is rotated by pushing the container, which moves the container onto the base and below the pressure plate, while ensuring that the center of the container is aligned with the center of the pressure plate.

[0056] The lifting rod is extended, which drives the hydraulic rod, connecting block, connecting rod, flange, and pressure plate to move upward through the crossbar and bracket. The space between the pressure plate and the base is adjusted to match the height of the rubber barrel. Then, the hydraulic rod is extended, and the hydraulic rod pushes the connecting block downward under the support of the bracket. The connecting block drives the connecting rod to move downward. The connecting rod drives the pressure plate downward through the flange and extends into the rubber barrel to cooperate.

[0057] As the hydraulic rod continues to extend, the pressure plate, after engaging with the rubber barrel, squeezes the liquid silicone downwards. The liquid silicone is squeezed into the inside of the flange and passes through the flange into the connecting pipe, then through the connecting pipe into the three-way valve, and finally through the three-way valve into the pipeline for injecting and delivering liquid silicone, and then supplied to the equipment using silicone along the pipeline.

[0058] Push the T-ring downwards. Under the action of external force, the T-ring overcomes the friction between the guide groove and the guide block and pushes the guide block downwards. The guide block and the T-ring move downwards along the guide groove. The T-ring moves downwards and squeezes the switch, causing the switch to be pressed and triggered. After the switch is triggered, it controls the electric rod to extend. The electric rod, supported by the sleeve, uses the telescopic end to push the motor downwards. At the same time, the motor starts and uses the drive end to drive the shaft to rotate.

[0059] Driven by the electric rod, the motor pushes the shaft downward along the sleeve, which in turn pushes the agitator downward. The agitator moves the rubber disc downward and inserts it into the liquid silicone in the rubber container. At the same time, the motor drives the agitator to rotate through the shaft, which in turn rotates the rubber disc, thus stirring the liquid silicone and preventing it from solidifying due to prolonged standing.

[0060] After the silicone injection is completed, the hydraulic rod is controlled to retract. The hydraulic rod uses its telescopic end to move upward through the connecting block, connecting rod and flange to pull the pressure plate out of the rubber barrel. The rubber barrel is removed from the base. The insert rod and the support rod are inserted. The insert rod drives the first joint connected to it to connect with the guide channel. The insert rod drives the arc plate to be set on the outside of the pressure plate. The bent plate uses the second joint connected to its lower end to connect with the arc plate to ensure that the bent plate extends to the inside of the flange. The bent plate and the arc plate are fixedly connected by the fixing parts, so that the cotton brush and scraper are in contact with the inner wall of the flange and the pressure plate.

[0061] Unscrew the threaded cap using the threaded action, inject the solvent into the inside of the bellows from the threaded cap for storage, and then reinstall the threaded cap using the threaded action after injection; loosen the bolts to separate the rubber pad from the push plate, releasing the fixing effect on the push plate, and push the push plate towards the flange. The push plate pushes the pressure plate away from the flange center along the through groove. At the same time, rotate the sleeve to rotate the pressure plate together through the T-ring, so that the pressure plate rotates to the top of the bellows. Then tighten the bolts and use the rubber pad to press and fix the push plate, so that the pressure plate is fixed at the corresponding position above the bellows.

[0062] The T-ring is pushed, and under the action of external force, the T-ring pushes the sleeve to rotate around the flange as the center through the guide block. During the rotation of the sleeve, the support plate rotates together with it. The support plate rotates together with the support rod. The support rod rotates together with the insertion rod around the flange as the center. The insertion rod drives the arc plate to rotate outside the pressure plate. The arc plate drives the bending plate to rotate together through the fixed component. The bending plate and the arc plate drive the cotton brush and scraper to rotate together. During the rotation, the scraper and cotton brush clean the adhesive material adhering to the lower end of the pressure plate and the inner wall of the flange.

[0063] Push the T-ring downwards along the guide groove. The T-ring drives the pressure plate downwards together. During the downward movement, the pressure plate squeezes and folds the bellows. During the squeezing process, the bellows uses pressure to squeeze the solvent stored inside through the one-way valve into the guide channel. The solvent flows along the guide channel into the first connector and through the first connector into the inside of the insert rod. The solvent flows through the insert rod into the liquid channel. After filling the liquid channel, it is sprayed out through the perforation onto the lower end of the pressure plate and the inner wall of the flange. The solvent, in conjunction with the cotton brush and scraper, cleans the adhesive on the lower end face of the pressure plate and the inner wall of the flange, improving the cleaning effect and preventing the adhesive from solidifying on the lower end face of the pressure plate and the inner wall of the flange after a long period of shutdown.

[0064] The above-described solution of the present invention has at least the following beneficial effects:

[0065] By integrating trigger-activated stirring and rotary spray cleaning functions, the system achieves unified operation of silicone uniform stirring and automatic equipment cleaning. The stirring unit utilizes a T-ring to push a trigger switch downwards, automatically activating an electric lever to drive the motor and stirring components into the silicone tank. The stirring plate and disc rotate to stir the liquid silicone, preventing stratification and localized solidification. The cleaning unit is quickly installed via a plug-in rod and support rod. Rotating the T-ring drives the rotating sleeve to rotate around the flange, while a cotton brush and scraper clean the pressure plate and flange. The extrusion spray unit uses a corrugated bladder to spray the solvent through guide channels and liquid channels onto the cleaning surface, working in conjunction with mechanical scraping for enhanced cleaning efficiency and effectiveness, shortening equipment maintenance time, and significantly improving injection quality and production efficiency.

[0080] Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the invention and to fully convey the scope of the invention to those skilled in the art.

[0081] like Figures 1 to 11 As shown, an embodiment of the present invention provides a liquid silicone injection machine, including a base 1 and a lifting rod 4 fixed on the base 1. A crossbar 5 is fixed to the telescopic end of the lifting rod 4. A hydraulic rod 7 is connected to the crossbar 5. A connecting rod 9 is connected to the lower end of the hydraulic rod 7. A flange 10 is connected to the lower end of the connecting rod 9. A pressure plate 11 is connected to the lower end of the flange 10. A connecting pipe 12 is connected to the outside of the flange 10 and communicates with the pressure plate 11. A three-way valve 13 is connected to the upper end of the connecting pipe 12 for connecting the pipeline for injecting liquid silicone for injection. The machine also includes:

[0082] The agitation part is located on the outside of the flange 10 and is rotated and sealed through the pressure plate 11. It includes a trigger element located on the outside of the flange 10 and an agitator element that can be raised and lowered through the pressure plate 11. The agitator element is electrically connected to the trigger element and is rotated and raised and sealed with the pressure plate 11.

[0083] The cleaning and scraping part is rotatably disposed on the outside of the flange 10 and on the outside of the pressure plate 11, and is detachably connected to the agitation part. It includes a connecting member rotatably disposed on the outside of the flange 10 and connected to the trigger member, and a scraping member sleeved on the outside of the pressure plate 11 and extending to the inside of the flange 10, and the scraping member is inserted into the connecting member.

[0084] The extrusion spray section is provided on the cleaning section and the agitation section. It includes an adjustment part that passes through the triggering part, a storage and supply part that is provided on the connecting rotating part, and a spray guide part that passes through the scraping part.

[0085] Specifically, a controller 2 is fixed on the base 1, and rollers 3 are inlaid and rotatably connected to both sides of the base 1. The rollers 3 are located below the pressure plate 11. A bracket 6 is connected below the crossbar 5. The bracket 6 is located outside the hydraulic rod 7. A connecting block 8 is connected to the telescopic end of the hydraulic rod 7. The lower end of the connecting block 8 is connected to the connecting rod 9.

[0086] In practical application, the base 1 provides stable support for the controller 2 and the lifting rod 4. The controller 2 can control the operation of all electrical components of the injection molding machine under the operation of the operator. The roller 3 can rotate under the push of external force. The base 1 provides a support space for the rubber barrel. The rubber barrel can rub against the roller 3 under the action of external force, thereby pushing the roller 3 to rotate, so that the rubber barrel can be moved to the base 1 more easily. The lifting rod 4 provides support for the crossbar 5. The crossbar 5 provides support for the bracket 6, so that the bracket 6 can stably support the hydraulic rod 7. The hydraulic rod 7 can support and push the connecting block 8 with the telescopic end. The connecting block 8 can provide support for the connecting rod 9. The connecting rod 9 can provide support for the flange 10 with the fixed component. The flange 10 can provide support for the pressure plate 11. The pressure plate 11 and the flange 10 can provide a channel for the liquid silicone in the rubber barrel to flow into the connecting pipe 12. The connecting pipe 12 can provide a channel for the silicone to enter the three-way valve 13.

[0087] The operator can connect the injection pipeline for delivering liquid silicone to the three-way valve 13 as needed, and adjust the opening of the three-way valve 13 as required. Then, the operator can control the extension of the lifting rod 4, allowing it to use its telescopic end to drive the hydraulic rod 7, connecting block 8, connecting rod 9, flange 10, and pressure plate 11 upwards via the crossbar 5 and bracket 6. This adjusts the space between the pressure plate 11 and the base 1. Next, the silicone barrel is brought into contact with the roller 3, and the silicone barrel pushes the roller 3 to rotate, moving the silicone barrel onto the base 1 and placing it below the pressure plate 11. Simultaneously, the center of the silicone barrel is aligned with the center of the pressure plate 11. Afterwards, adjustments can be made as needed. The hydraulic rod 7 needs to be extended to push the connecting block 8 downwards under the support of the bracket 6. The connecting block 8 then moves the connecting rod 9 downwards, which in turn moves the pressure plate 11 downwards through the flange 10. The pressure plate 11 then extends into the rubber barrel to engage with the rubber barrel. The hydraulic rod 7 can be extended as needed so that the pressure plate 11 can squeeze the liquid silicone in the rubber barrel downwards after engaging with it. The liquid silicone is squeezed into the inside of the flange 10, passes through the flange 10, enters the connecting pipe 12, and then passes through the connecting pipe 12 into the three-way valve 13. Subsequently, it passes through the three-way valve 13 into the injection delivery pipeline for liquid silicone, and is supplied to the equipment using silicone along this pipeline.

[0088] In a preferred embodiment of the present invention, the trigger includes:

[0089] T-ring 17 is located on the outside of flange 10;

[0090] Support plate 29 is located on one side of flange 10 and below T-ring 17;

[0091] Switch 47 is fixed on support plate 29.

[0092] Specifically, flange 10 provides stable support for support plate 29, support plate 29 provides support for switch 47, T-ring 17 can move up and down along guide groove 15 with guide block 16 under the action of external force, and T-ring 17 can squeeze and trigger switch 47 under the action of external force. Switch 47 is electrically connected to motor 40 and electric rod 39, so that after being triggered, it controls electric rod 39 to extend and starts motor 40 to rotate. When the external force on switch 47 disappears, it will rebound, thereby controlling electric rod 39 to retract and reset, and stopping motor 40 from running.

[0093] The mixing components include:

[0094] Sleeve 38 is installed above the pressure plate 11;

[0095] The electric pole 39 is fixedly installed at the upper end of the through sleeve 38;

[0096] Motor 40 is fixed to the telescopic end of electric rod 39 and located inside sleeve 38;

[0097] Heat dissipation vent 41, through sleeve 38 and pressure plate 11 are provided;

[0098] The mixing component is located below the motor 40 and is sealed through the pressure plate 11.

[0099] Specifically, the pressure plate 11 provides stable support for the sleeve 38, the sleeve 38 provides lifting space for the telescopic ends of the motor 40 and the electric rod 39, and the sleeve 38 provides stable support for the electric rod 39 under the support of the pressure plate 11. The electric rod 39 provides support for the motor 40. The pressure plate 11 and the sleeve 38 provide space for the heat dissipation vent 41, which provides a channel for the heat generated by the motor 40 during operation, facilitating heat dissipation.

[0100] The mixing components include:

[0101] The shaft 42 is movably disposed through the lower end of the sleeve 38 and is connected to the drive end of the motor 40;

[0102] The multi-layer sealing ring 43 is fixed to the inner side of the sleeve 38 and fits against the outer side of the shaft 42;

[0103] The groove 44 is formed on the lower end face of the pressure plate 11 and is connected to the sleeve 38;

[0104] The stirring plate 45 is symmetrically fixed on the outside of the shaft 42 and located inside the groove 44;

[0105] The rubber disc 46 is fixed to the lower end of the stirring plate 45 and is sealed to the pressure plate 11 in the groove 44.

[0106] Specifically, the motor 40 provides support for the shaft 42 and drives the shaft 42 to rotate; the sleeve 38 provides stable support for the multi-layer sealing ring 43; the multi-layer sealing ring 43 is made of rubber and can fit against the shaft 42 using its elasticity to achieve a sealing effect; the pressure plate 11 provides opening space for the groove 44; the groove 44 provides storage space for the stirring plate 45 and the rubber disc 46; the rubber disc 46 can fit against the pressure plate 11 using its elasticity to achieve a sealing effect.

[0107] In practical application, the operator can push the T-ring 17 downwards as needed, allowing it to overcome the friction between the guide groove 15 and the guide block 16 under external force. This allows the guide block 16 and the T-ring 17 to move downwards along the guide groove 15, enabling the T-ring 17 to press and trigger the switch 47. Once triggered, the switch 47 will extend the electric rod 39, which, supported by the sleeve 38, will push the motor 40 downwards via its telescopic end. Simultaneously, the motor 40 will start and drive the shaft 42 to rotate via its drive end. The motor 40 will then push downwards along the sleeve 38 under the push of the electric rod 39. The moving shaft 42 moves, causing it to push the stirring plate 45 downwards. The stirring plate 45 then moves the glue disc 46 downwards, allowing both the glue disc 46 and the stirring plate 45 to extend into the liquid silicone in the glue container. Simultaneously, the motor 40 drives the stirring plate 45 to rotate via the shaft 42, which in turn drives the glue disc 46 to rotate. This allows the stirring plate 45 and the glue disc 46 to use rotational power to stir the liquid silicone, preventing it from solidifying due to prolonged standing. Furthermore, the downward movement of the T-ring 17 triggers the switch 47, extending its operating stroke and greatly reducing the possibility of accidental activation. This also prevents the motor 40 and the electric lever 39 from accidentally activating and affecting the glue dispensing process.

[0108] In a preferred embodiment of the present invention, the connecting member includes:

[0109] The sleeve 14 is rotatably connected to the outside of the flange 10 via a bearing;

[0110] Guide grooves 15 are symmetrically opened on the outer side of the sleeve 14;

[0111] T-ring 17 is located on the outside of sleeve 14 and is guided and connected to guide groove 15 for lifting and lowering movement;

[0112] Support rod 18 is connected to the outside of support plate 29.

[0113] Specifically, a guide block 16 is provided on the inner side of the guide groove 15, and the guide block 16 is connected to the inner side of the T-ring 17. The flange 10 can provide rotational support for the sleeve 14 through the bearing. The sleeve 14 can provide opening space for the guide groove 15. The guide groove 15 can provide a guiding function for the lifting and moving of the guide block 16. The T-ring 17 can push the guide block 16 to move up and down along the guide groove 15 under the action of external force. The sleeve 14 can provide support for the support plate 29. The support plate 29 can provide stable support for the support rod 18. The support plate 29 and the support rod 18 can rotate together with the sleeve 38.

[0114] Scratching components include:

[0115] The socket 20 is located at the end of the support rod 18;

[0116] The insertion rod 21 has one end inserted into the inside of the socket 20;

[0117] Arc plate 23 is sleeved on the outside of pressure plate 11 and connected to the other end of insertion rod 21;

[0118] The bent plate 28 is connected to the end of the arc plate 23 by a fixing component and extends to the inside of the flange 10;

[0119] Cotton brush 26 is fixed to the side of the arc plate 23 and the curved plate 28 near the pressure plate 11;

[0120] The scraper 27 is fixed to the side of the arc plate 23 and the curved plate 28 near the pressure plate 11 and is adjacent to the cotton brush 26.

[0121] Specifically, the support rod 18 provides space for the insertion port 20, the insertion port 20 provides space for the insertion rod 21, and together with the support rod 18, it provides support for the insertion rod 21. The insertion rod 21 provides support for the arc plate 23, and the arc plate 23 provides support for the bent plate 28 using a fixing component. The bent plate 28 and the arc plate 23 can stably support the cotton brush 26 and the scraper 27. The cotton brush 26 can wipe the adhesive material adhering to the lower end face of the pressure plate 11 under the action of external force, while the scraper 27 can scrape off the adhesive material on the lower end face of the pressure plate 11, making the adhesive material cleaner. The lower end of the bent plate 28 is connected to a second connector 48.

[0122] In practical application, when the operator needs to use the pressure plate 11 to squeeze and inject glue into the glue barrel, the fixed parts connected to the arc plate 23 and the bent plate 28 need to be removed first, and the bent plate 28 needs to be separated from the arc plate 23. Then, the arc plate 23 is pulled away from the center of the pressure plate 11, so that the arc plate 23 drives the insertion rod 21 and the first connector 22 to move together, so that the first connector 22 connected to the insertion rod 21 is separated from the guide 19, and the insertion rod 21 is separated from the support rod 18, thereby disassembling the arc plate 23 and the bent plate 28, and then driving the cotton brush 26 and the scraper 27 to be disassembled together. After that, the hydraulic rod 7 is controlled to extend and the pressure plate 11 is inserted into the glue barrel to squeeze and inject glue.

[0123] After the silicone injection is completed, the operator can control the hydraulic rod 7 to retract, causing the hydraulic rod 7 to extend upwards via the connecting block 8, connecting rod 9, and flange 10, pulling the pressure plate 11 out of the rubber barrel and removing the rubber barrel from the base 1. Then, the insert rod 21 is inserted into the support rod 18, simultaneously causing the first connector 22 connected to it to connect with the guide channel 19. This allows the insert rod 21 to move the arc plate 23 to the outside of the pressure plate 11. Finally, the curved plate 28 is connected to the arc plate 23 via the second connector 48 connected to its lower end (e.g., ...). Figure 12As shown), the bent plate 28 extends to the inside of the flange 10, and the bent plate 28 and the arc plate 23 are fixedly connected by fixing components, so that the cotton brush 26 and the scraper 27 can contact and fit with the inner wall of the flange 10 and the pressure plate 11. Then, the operator can push the T-ring 17 as needed, so that the T-ring 17 pushes the sleeve 14 to rotate around the flange 10 under the action of external force through the guide block 16. The center of the flange 10 and the center of the pressure plate 11 are on the same center line, so that the sleeve 14 can drive the support plate 29 to rotate together during the rotation, so that the support plate 29 drives the support rod 1 When the support rod 18 rotates together with the flange 10, the insertion rod 21 will rotate around the flange 10. The insertion rod 21 will then rotate the arc plate 23 on the outside of the pressure plate 11. The pressure plate 11 will rotate the bending plate 28 through the fixed component. This allows the bending plate 28 and the arc plate 23 to rotate the cotton brush 26 and the scraper 27 together. During the rotation, the scraper 27 and the cotton brush 26 can clean the adhesive material adhering to the lower end of the pressure plate 11 and the inner wall of the flange 10, preventing the adhesive material from solidifying on the lower end face of the pressure plate 11 and the inner wall of the flange 10 after a long period of shutdown, thus improving the cleaning effect and efficiency.

[0124] In a preferred embodiment of the present invention, the adjusting component includes:

[0125] The through groove 33 is opened through one side and the front of the T-ring 17;

[0126] Push plate 34, through the front of through slot 33;

[0127] The pressure plate 35 is located inside the through groove 33 and is connected to the push plate 34;

[0128] Bolt 36, threaded through T-ring 17 and extending to the inside of through groove 33;

[0129] The rubber pad 37 is fixed to the lower end of the bolt 36 to compress and fix the push plate 34.

[0130] Specifically, the T-ring 17 provides space for the through groove 33, which provides a through channel for the pressure plate 35 and the push plate 34, and provides storage space for the pressure plate 35. It also provides threaded support for the bolt 36 using the thread action. The bolt 36 provides support for the rubber pad 37, and the bolt 36 can move up and down using the thread action with the T-ring 17, and can also move the rubber pad 37 up and down together. The rubber pad 37 is made of rubber and can use friction to press and fix the position of the push plate 34 under the action of external force.

[0131] Storage and supply parts include:

[0132] The corrugated bag 30 is fixed on the support plate 29;

[0133] A one-way valve 31 is installed through the lower end of the bellows bladder 30;

[0134] The threaded cap 32 is provided with threads that penetrate the upper end of the bellows bladder 30.

[0135] Specifically, the support plate 29 provides stable support for the bellows 30, the bellows 30 provides storage space for the solvent, and the bellows 30 can be squeezed and folded under external force, and will rebound and reset when the external force is removed. The one-way valve 31 is a valve type, which can open the channel under the pressure inside the bellows 30, and can only provide a channel for the solvent in the bellows 30 to enter the guide channel 19.

[0136] The nozzle guide includes:

[0137] The support rod 18 has a through-hole guide 19, which is connected to the one-way valve 31.

[0138] The first connector 22 is fixed to one end of the insertion rod 21 and is inserted into the guide channel 19;

[0139] Liquid channel 24 is formed inside the arc plate 23 and the curved plate 28;

[0140] Perforation 25 is provided on the side of the curved plate 23 and the bent plate 28 near the pressure plate 11;

[0141] The bent plate 28 is connected to the arc plate 23 via the second joint 48.

[0142] Specifically, the guide channel 19 provides a channel for the solvent to enter the first connector 22, the first connector 22 provides a channel for the solvent in the guide channel 19 to enter the liquid channel 24 in the arc plate 23, the second connector 48 provides a channel for the solvent in the arc plate 23 to enter the liquid channel 24 in the curved plate 28, and the perforation 25 provides a channel for the solvent in the liquid channel 24 to be sprayed to the outside. The perforation 25 is located between the cotton brush 26 and the scraper 27.

[0143] In practical application, before using the cotton brush 26 and scraper 27, the operator can unscrew the threaded cap 32 using the threaded action and inject the solvent into the inside of the bellows bladder 30 through the threaded cap 32 for storage. The bellows bladder 30 is made of transparent rubber, which allows for easy observation of the liquid level. After injection, the threaded cap 32 is reinstalled using the threaded action. When using the cotton brush 26 and scraper 27, the operator can loosen the bolt 36 as needed, causing the bolt 36 to separate the rubber pad 37 from the push plate 34, thus releasing the fixing effect on the push plate 34. Then, the push plate 34 is pushed towards the flange 10, causing the push plate 34 to push the pressure plate 35 away from the center of the flange 10 along the through groove 33. At the same time, the rotating sleeve 14 rotates the pressure plate 35 through the T-ring 17, causing the pressure plate 35 to rotate to the top of the bellows bladder 30. Then, the operator can tighten the bolt 36 and use the rubber pad 37 to press and fix the push plate 34. This allows the pressure plate 35 to be fixed at the corresponding position above the bellows 30. Then, the operator can push the T-ring 17 downwards along the guide groove 15, causing the T-ring 17 to move the pressure plate 35 downwards together. During the downward movement, the pressure plate 35 can squeeze the bellows 30 to fold, allowing the bellows 30 to use pressure to squeeze the solvent stored inside through the one-way valve 31 into the guide channel 19. The solvent will then flow along the guide channel 19 into the first connector 22 and pass through the first connector 22 into the inside of the insert rod 21. The insert rod 21 has an internal hollow structure, allowing the solvent to flow through the insert rod 21 into the liquid channel 24. After filling the liquid channel 24, it will be sprayed out through the perforation 25 onto the lower end of the pressure plate 11 and the inner wall of the flange 10. This allows the solvent, in conjunction with the cotton brush 26 and the scraper 27, to clean the adhesive adhering to the lower end face of the pressure plate 11 and the inner wall of the flange 10, improving the cleaning effect.

[0144] As a preferred embodiment of the present invention, a method of using a liquid silicone injection molding machine includes:

[0145] The rubber barrel containing liquid silicone is brought into contact with the roller 3. The roller 3 is rotated by pushing the rubber barrel, so that the rubber barrel is moved to the base 1 and below the pressure plate 11, while ensuring that the center of the rubber barrel is aligned with the center of the pressure plate 11.

[0146] The lifting rod 4 is extended, which drives the hydraulic rod 7, connecting block 8, connecting rod 9, flange 10 and pressure plate 11 to move upward through the crossbar 5 and bracket 6. The space between the pressure plate 11 and the base 1 is adjusted to match the height of the rubber barrel. Then, the hydraulic rod 7 is extended, and the hydraulic rod 7 pushes the connecting block 8 downward under the support of the bracket 6. The connecting block 8 drives the connecting rod 9 to move downward. The connecting rod 9 drives the pressure plate 11 to move downward through the flange 10 and extend into the rubber barrel to cooperate.

[0147] As the hydraulic rod 7 continues to extend, the pressure plate 11, after engaging with the rubber barrel, squeezes the liquid silicone in the rubber barrel downwards. The liquid silicone is squeezed into the inside of the flange 10 and passes through the flange 10 into the connecting pipe 12, then through the connecting pipe 12 into the three-way valve 13, and finally through the three-way valve 13 into the pipeline for injecting and conveying liquid silicone, and is supplied to the equipment using silicone along the pipeline.

[0148] Pushing T-ring 17 downwards, T-ring 17 overcomes the friction between guide groove 15 and guide block 16 under the action of external force and pushes guide block 16 downwards. Guide block 16 and T-ring 17 move downwards along guide groove 15. T-ring 17 moves downwards and squeezes switch 47, causing switch 47 to be pressed and triggered. After switch 47 is triggered, it controls electric rod 39 to extend. Electric rod 39, supported by sleeve 38, uses telescopic end to push motor 40 downwards. At the same time, motor 40 starts and uses drive end to drive shaft 42 to rotate.

[0149] Under the push of the electric rod 39, the motor 40 pushes the shaft 42 downward along the sleeve 38. The shaft 42 pushes the stirring plate 45 downward. The stirring plate 45 drives the glue disc 46 to move downward together and extend into the liquid silicone in the glue container. At the same time, the motor 40 drives the stirring plate 45 to rotate through the shaft 42 via the drive end. The stirring plate 45 drives the glue disc 46 to rotate together, stirring the liquid silicone and preventing the liquid silicone from solidifying due to prolonged standing.

[0150] After the silicone injection is completed, the hydraulic rod 7 is controlled to retract. The hydraulic rod 7 uses its telescopic end to drive the pressure plate 11 to be pulled out of the rubber barrel through the connecting block 8, connecting rod 9 and flange 10. The rubber barrel is removed from the base 1. The insert rod 21 is inserted into the support rod 18. The insert rod 21 drives the first connector 22 connected to it to be inserted into the guide 19. The insert rod 21 drives the arc plate 23 to be set on the outside of the pressure plate 11. The bent plate 28 uses the second connector 48 connected to its lower end to be inserted into the arc plate 23 to ensure that the bent plate 28 extends to the inside of the flange 10. The bent plate 28 and the arc plate 23 are fixedly connected by the fixing component, so that the cotton brush 26 and scraper 27 are in contact with the inner wall of the flange 10 and the pressure plate 11.

[0151] Using the threaded action, unscrew the threaded cap 32 and inject the solvent into the inside of the bellows 30 for storage. After injection, use the threaded action to reinstall the threaded cap 32. Loosen the bolt 36 to separate the rubber pad 37 from the push plate 34, releasing the fixing effect on the push plate 34. Push the push plate 34 towards the flange 10. The push plate 34 pushes the pressure plate 35 along the through groove 33 to move away from the center of the flange 10. At the same time, rotate the sleeve 14 to rotate the pressure plate 35 together through the T-ring 17, so that the pressure plate 35 rotates to the top of the bellows 30. Then tighten the bolt 36 and use the rubber pad 37 to press and fix the push plate 34, so that the pressure plate 35 is fixed at the corresponding position above the bellows 30.

[0152] The T-ring 17 is pushed, and under the action of external force, the T-ring 17 pushes the sleeve 14 to rotate around the flange 10 through the guide block 16. During the rotation, the sleeve 14 drives the support plate 29 to rotate together, the support plate 29 drives the support rod 18 to rotate together, the support rod 18 drives the insertion rod 21 to rotate around the flange 10, the insertion rod 21 drives the arc plate 23 to rotate outside the pressure plate 11, the arc plate 23 drives the bending plate 28 to rotate together through the fixed component, the bending plate 28 and the arc plate 23 drive the cotton brush 26 and the scraper 27 to rotate together, and the scraper 27 and the cotton brush 26 clean the adhesive material adhering to the lower end of the pressure plate 11 and the inner wall of the flange 10 during the rotation.

[0153] The T-ring 17 is pushed downward along the guide groove 15. The T-ring 17 drives the pressure plate 35 to move downward together. During the downward movement, the pressure plate 35 squeezes the bellows 30 to fold. During the squeezing process, the bellows 30 uses pressure to squeeze the solvent stored inside through the one-way valve 31 into the guide channel 19. The solvent flows along the guide channel 19 into the first connector 22 and through the first connector 22 into the inside of the insert rod 21. The solvent flows through the insert rod 21 into the liquid channel 24. After filling the liquid channel 24, it is sprayed through the perforation 25 onto the lower end of the pressure plate 11 and the inner wall of the flange 10. The solvent, in conjunction with the cotton brush 26 and the scraper 27, cleans the adhesive on the lower end face of the pressure plate 11 and the inner wall of the flange 10, improving the cleaning effect and preventing the adhesive from solidifying on the lower end face of the pressure plate 11 and the inner wall of the flange 10 after a long period of shutdown.

[0154] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.

The roller is rotated by pushing the container, which moves the container onto the base and below the pressure plate, while ensuring that the center of the container is aligned with the center of the pressure plate. The lifting rod is extended, which drives the hydraulic rod, connecting block, connecting rod, flange, and pressure plate to move upward through the crossbar and bracket, adjusting the space between the pressure plate and the base to match the height of the rubber barrel; then the hydraulic rod is extended, and the hydraulic rod pushes the connecting block downward under the support of the bracket, the connecting block drives the connecting rod to move downward, and the connecting rod drives the pressure plate downward through the flange and extends into the rubber barrel to cooperate; As the hydraulic rod continues to extend, the pressure plate, after engaging with the rubber barrel, squeezes the liquid silicone downwards. The liquid silicone is squeezed into the inside of the flange and passes through the flange into the connecting pipe, then through the connecting pipe into the three-way valve, and finally through the three-way valve into the pipeline for injecting and delivering liquid silicone, and then supplied to the equipment using silicone along the pipeline. Push the T-ring downwards. Under the action of external force, the T-ring overcomes the friction between the guide groove and the guide block and pushes the guide block downwards. The guide block and the T-ring move downwards along the guide groove. The T-ring moves downwards and squeezes the switch, causing the switch to be pressed and triggered. After the switch is triggered, it controls the electric rod to extend. The electric rod, supported by the sleeve, uses the telescopic end to push the motor downwards. At the same time, the motor starts and uses the drive end to drive the shaft to rotate. Driven by the electric rod, the motor pushes the shaft downward along the sleeve, which in turn pushes the agitator downward. The agitator moves the rubber disc downward and inserts it into the liquid silicone in the rubber container. At the same time, the motor drives the agitator to rotate through the shaft, which in turn rotates the rubber disc, thus stirring the liquid silicone and preventing it from solidifying due to prolonged standing. After the silicone injection is completed, the hydraulic rod is controlled to retract. The hydraulic rod uses its telescopic end to move upward through the connecting block, connecting rod and flange to pull the pressure plate out of the rubber barrel. The rubber barrel is removed from the base. The insert rod and the support rod are inserted. The insert rod drives the first joint connected to it to connect with the guide channel. The insert rod drives the arc plate to be set on the outside of the pressure plate. The bent plate uses the second joint connected to its lower end to connect with the arc plate to ensure that the bent plate extends to the inside of the flange. The bent plate and the arc plate are fixedly connected by the fixing parts, so that the cotton brush and scraper are in contact with the inner wall of the flange and the pressure plate. Unscrew the threaded cap using the threaded action, inject the solvent into the inside of the bellows from the threaded cap for storage, and then reinstall the threaded cap using the threaded action after injection; loosen the bolts to separate the rubber pad from the push plate, releasing the fixing effect on the push plate, and push the push plate towards the flange. The push plate pushes the pressure plate away from the flange center along the through groove. At the same time, rotate the sleeve to rotate the pressure plate together through the T-ring, so that the pressure plate rotates to the top of the bellows. Then tighten the bolts and use the rubber pad to press and fix the push plate, so that the pressure plate is fixed at the corresponding position above the bellows. The T-ring is pushed, and under the action of external force, the T-ring pushes the sleeve to rotate around the flange as the center through the guide block. During the rotation of the sleeve, the support plate rotates together with it. The support plate rotates together with the support rod. The support rod rotates together with the insertion rod around the flange as the center. The insertion rod drives the arc plate to rotate outside the pressure plate. The arc plate drives the bending plate to rotate together through the fixed component. The bending plate and the arc plate drive the cotton brush and scraper to rotate together. During the rotation, the scraper and cotton brush clean the adhesive material adhering to the lower end of the pressure plate and the inner wall of the flange. Push the T-ring downwards along the guide groove. The T-ring drives the pressure plate downwards together. During the downward movement, the pressure plate squeezes and folds the bellows. During the squeezing process, the bellows uses pressure to squeeze the solvent stored inside through the one-way valve into the guide channel. The solvent flows along the guide channel into the first connector and through the first connector into the inside of the insert rod. The solvent flows through the insert rod into the liquid channel. After filling the liquid channel, it is sprayed out through the perforation onto the lower end of the pressure plate and the inner wall of the flange.
