Description

Technical Field

[0001] This utility model relates to the field of production mold technology, and in particular to a production mold for an easy-to-clean condiment bottle cap. Background Technology

[0002] As a core component of food packaging, the development of production molds for condiment bottle caps directly affects the product's sealing performance, ease of opening, and appearance quality. Traditional molds mostly adopt injection molding processes, using food-grade plastics such as polypropylene and polyethylene as raw materials, and achieve mass production through two-plate or three-plate mold structures. With the increasing demand for functionality in the consumer market, mold design needs to have multiple composite functions, often using hot runner systems to reduce waste rate, and combining software simulation to optimize gate design.

[0003] In the prior art, after long-term use, production molds need to be disassembled for cleaning and maintenance in order to ensure the accuracy of mold forming. However, molds are often fixed to the moving mechanism with bolts, and disassembly and assembly require a lot of time, which increases the difficulty of cleaning and maintaining the molds for workers and makes the maintenance efficiency of the molds relatively low. Therefore, in order to solve the above problems, this utility model proposes a production mold for easy-to-clean condiment bottle caps. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a production mold for easy-to-clean condiment bottle caps. By using an electromagnet and spring to adjust the limiting block and the groove, the mold plate can be quickly disassembled and assembled, making it easier and faster for workers to clean the device. Compared with the connection and fixation by bolts, it reduces the time spent on maintenance and disassembly, improves the maintenance efficiency of the mold, and ensures the durability of the equipment.

[0005] This utility model provides the following technical solution: a production mold for easy-to-clean condiment bottle caps, including a base, a fixing plate one fixedly installed on the upper part of the base, a fixing plate two fixedly installed on the upper part of the base and directly to the right of the fixing plate one, guide rods evenly fixedly installed between the fixing plate one and the fixing plate two, the number of guide rods being four, a sliding plate movably sleeved on the guide rod, a sliding groove opened on the left side of the sliding plate, the number of sliding grooves being two and symmetrically distributed vertically, a cavity opened on the right side of the sliding groove, an electromagnet fixedly installed in the right side of the cavity, springs fixedly installed in the cavity on both sides before and after the electromagnet, and a movable plate fixedly installed at the extension end of the spring. A metal sheet is fixedly installed on the right side of the movable plate, and a limit block is fixedly installed on the left side of the movable plate. The limit block is movably connected to the slide groove. A mold plate is provided on the left side of the movable plate, and two ribs are fixedly installed on the right side of the mold plate. Each rib is fitted with a slide groove, and a groove is formed on the right side of the rib. The groove engages with the limit block. Two handrails are fixedly installed on the front of the mold plate and are symmetrically distributed vertically. The engagement between the limit block and the groove is adjusted by an electromagnet and a spring, enabling quick assembly and disassembly of the mold plate. This makes cleaning the device easier and faster for workers, reduces the time spent on maintenance and disassembly, improves the efficiency of mold maintenance, and ensures the durability of the equipment.

[0006] Preferably, the mold plate has an air cavity inside, and mold grooves are evenly distributed on the right side of the mold plate. A Teflon anti-stick layer is sprayed in the mold grooves. Pipes are evenly distributed in the mold plate, and the number of pipes is the same as the number of mold grooves. The left and right ends of the pipes are fixedly connected to the mold grooves and the air cavity, respectively. The Teflon anti-stick layer sprayed in the mold grooves reduces the adhesion between the injection molding material and the mold, preventing the material from adhering to the mold grooves, which is beneficial for subsequent bottle cap demolding.

[0007] Preferably, an air nozzle is fixedly installed at the connection between the first pipe and the mold groove, an air pump is fixedly installed on the right side of the sliding plate, and a second pipe is opened in the sliding plate. The right end of the second pipe is fixedly connected to the air pump, and the left end of the second pipe fits into the right side of the air chamber. When the air pump is started, air is injected into the air chamber through the second pipe. The airflow passes through the first pipe and is discharged into the mold groove through the air nozzle, so that the airflow blows out the formed bottle cap. Compared with using a push rod to push out the bottle cap, this avoids the bottle cap sticking to the ejection mechanism.

[0008] Preferably, an injection molding plate is fixedly installed on the right side of the fixing plate, and injection ports are evenly distributed on the right side of the injection molding plate. The injection ports correspond to the mold grooves. Connecting blocks are evenly fixedly installed on the side of the injection molding plate, and the number of connecting blocks is four. Grooves are evenly distributed on the side of the mold plate, and the number of grooves is four, each of which fits into the connecting blocks. By utilizing the fit between the connecting blocks and the grooves, the mold plate and the injection molding plate are made to fit tightly, which helps to improve the accuracy of the overlap between the mold plate and the injection molding plate and prevents the injection ports from shifting from the mold grooves.

[0009] Preferably, a collection groove is provided on the upper part of the base and located at the lower right of the injection molding plate. A ramp is provided in the collection groove. A fixing block is fixedly installed on the left side of the fixing plate. The upper and lower parts of the fixing block are evenly connected to hydraulic rods through shafts. There are six hydraulic rods. After the bottle cap is demolded, it falls into the collection groove. The bottle cap slides out through the ramp provided in the collection groove, making it easy for the staff to take out the molded bottle cap.

[0010] Preferably, the left side of the fixed plate two, located on both sides of the fixed block, is evenly and movably connected to push rod one via shafts. There are six push rods one in total. The middle part of push rod one is movably connected to the telescopic end of the hydraulic rod via shaft. The left end of push rod one is movably connected to push rod two via shafts. There are eight push rod two in total. The left end of push rod two is movably connected to the sliding plate via shafts. The push rod one rotates by flexibly extending and retracting the telescopic end of the hydraulic rod. Push rod one pushes the sliding plate to move on the guide rod through the connection of push rod two, which facilitates the fitting and separation of the mold.

[0011] Compared with the prior art, the advantages of this utility model are as follows:

[0012] 1. By energizing the electromagnet, the moving plate moves the limiting block, breaking the engagement between the limiting block and the first groove. The sliding groove engages with the rib, and pulling the handle allows the mold plate to be removed from the sliding plate for easy cleaning. During installation, the inclined design on the limiting block causes the rib to slide in the sliding groove, squeezing the limiting block inside. The elastic potential energy of the spring causes the first groove to re-engage with the limiting block, enabling quick assembly and disassembly of the mold plate. This makes cleaning the device easier and faster for workers. Compared to bolted connections, this significantly reduces the time spent on maintenance and disassembly, improving maintenance efficiency for condiment bottle cap molds and ensuring equipment durability.

[0013] 2. The Teflon anti-stick layer sprayed in the mold groove reduces the adhesion between the injection molding material and the mold, preventing the material from sticking to the mold groove and facilitating subsequent cap demolding. The fit between the connecting block and the second groove improves the accuracy of the alignment between the mold plate and the injection plate, preventing the injection port from shifting from the mold groove. The air pump generates airflow to blow out the cap, preventing it from sticking to the ejection mechanism and avoiding the need for manual removal of the cap from the ejector rod. The cap falls into the collection groove and slides out through the ramp in the collection groove, making it easy for workers to remove the molded cap. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-6A production mold for easy-to-clean condiment bottle caps includes a base 1, a fixing plate 2 fixedly installed on the upper part of the base 1, a fixing plate 3 fixedly installed on the upper part of the base 1 and directly to the right of the fixing plate 2, guide rods 4 evenly fixed between the fixing plate 2 and the fixing plate 3, four guide rods 4 in total, sliding plates 5 movably sleeved on the guide rods 4, sliding plates 5 having two grooves 6 on the left side, symmetrically distributed vertically, and a cavity 7 on the right side of the grooves 6, an electromagnet 8 fixedly installed on the right side of the cavity 7, with electromagnets 8 located on the front and rear sides of the cavity 7 respectively. A spring 9 is fixedly installed, and a movable plate 10 is fixedly installed at the telescopic end of the spring 9. An iron sheet 11 is fixedly installed on the right side of the movable plate 10, and a limit block 12 is fixedly installed on the left side of the movable plate 10. The limit block 12 is movably connected to the slide groove 6. A mold plate 13 is provided on the left side of the sliding plate 5, and two ribs 14 are fixedly installed on the right side of the mold plate 13. Each rib 14 fits into the slide groove 6. A groove 15 is opened on the right side of the rib 14, and the groove 15 engages with the limit block 12. A handrail 16 is fixedly installed on the front of the mold plate 13. There are two handrails 16, which are symmetrically distributed vertically. When cleaning and maintenance of the mold plate 13 is required, the electromagnet 8 is energized to attract the iron sheet 11. The iron sheet 11 drives the moving plate 10 to move to the right, causing the limiting block 12 to move into the cavity 7, thus disengaging the locking between the limiting block 12 and the groove 15. The spring 9 is compressed, generating elastic potential energy. By utilizing the engagement between the slide groove 6 and the rib 14, the handle 16 can be pulled to remove the mold plate 13 from the sliding plate 5, facilitating the cleaning of the mold plate 13 and the mold groove 18 on it. Then, the electromagnet 8 is de-energized, and the elastic potential energy of the spring 9 causes the moving plate 10 to move the limiting block 12. During resetting and installation, the inclined design on the limiting block 12 allows the rib 14 to slide in the slide groove 6, squeezing the limiting block 12 into the interior of 7. When the groove 15 aligns with the limiting block 12, the elastic potential energy of the spring 9 is used to re-engage the groove 15 with the limiting block 12, thereby fixing the mold plate 13. This enables quick disassembly and assembly of the mold plate 13, making it easier and faster for workers to clean the device. Compared with bolted connections, this effectively reduces the time spent on maintenance and disassembly, improves the maintenance efficiency of the condiment bottle cap mold, and ensures the durability of the equipment.

[0023] An air cavity 17 is provided inside the mold plate 13. Mold grooves 18 are evenly distributed on the right side of the mold plate 13. A Teflon anti-stick layer is sprayed into the mold grooves 18. Pipes 19 are evenly distributed in the mold plate 13, and the number of pipes 19 is the same as that of the mold grooves 18. The left and right ends of pipes 19 are fixedly connected to the mold grooves 18 and the air cavity 17, respectively. An air nozzle 20 is fixedly installed at the connection between pipes 19 and the mold grooves 18. An air pump 21 is fixedly installed on the right side of the sliding plate 5. A second pipe 22 is provided in the sliding plate 5. The right end of pipe 22 is fixedly connected to the air pump 21, and the left end of pipe 22 fits into the right side of the air cavity 17. The Teflon anti-stick layer sprayed in the mold grooves 18 reduces the adhesion between the injection molding material and the mold, preventing the material from adhering to the mold grooves 18. In the middle, which is conducive to the subsequent demolding of bottle caps, an injection plate 23 is fixedly installed on the right side of the fixing plate 1 2. The injection plate 23 has injection ports 24 evenly opened on the right side, which correspond to the mold groove 18. Connecting blocks 25 are evenly fixedly installed on the side of the injection plate 23, and there are four connecting blocks 25. The side of the mold plate 13 has four grooves 26 evenly opened, which are respectively matched with the connecting blocks 25. A collection groove 27 is opened on the upper part of the base 1 and located on the lower right side of the injection plate 23. A ramp is provided in the collection groove 27. A fixing block 28 is fixedly installed on the left side of the fixing plate 23. The upper and lower parts of the fixing block 28 are evenly connected to hydraulic rods 29 through shafts, and there are six hydraulic rods 29. The left side of the fixing plate 23 and located on the upper and lower parts of the fixing block 28 are fixedly installed on the left side. Six push rods 30 are evenly connected to the side via shafts. The middle of each push rod 30 is movably connected to the telescopic end of the hydraulic rod 29 via a shaft. Eight push rods 31 are movably connected to the left end of each push rod 30 via a shaft. The left end of each push rod 31 is movably connected to the sliding plate 5 via a shaft. When the hydraulic rod 29 is activated, its telescopic end extends, causing the push rods 30 to rotate. The push rods 30, through the connection of the push rods 31, push the sliding plate 5 to move to the left on the guide rod 4. The sliding plate 5 moves the mold plate 13. By utilizing the fit between the connecting block 25 and the groove 26, the mold plate 13 and the injection plate 23 are made to fit tightly, which helps to improve the accuracy of the alignment between the mold plate 13 and the injection plate 23 and prevents the injection port 24 from aligning with the mold groove 18. When a deviation occurs, the injection is performed into the mold groove 18 through the injection port 24 on the injection plate 23. Due to the small opening on the air nozzle 20, the injection liquid will not enter the pipe 19 due to its own fluidity. After the injection is completed and cooled, the extension end of the hydraulic rod 29 retracts, causing the sliding plate 5 to drive the mold plate 13 back to its original position. The air pump 21 is started and air is supplied to the air chamber 17 through the second pipe 22. The airflow passes through the first pipe 19 and is discharged into the mold groove 18 from the air nozzle 20, causing the airflow to blow out the formed bottle cap. Compared with using the ejector rod to push out the bottle cap, this can prevent the bottle cap from sticking to the ejector mechanism and avoid the need to manually pull the bottle cap off the ejector rod. The bottle cap falls into the collection groove 27 and slides out through the ramp in the collection groove 27, making it easy for the staff to take out the formed bottle cap.

[0024] Working principle: The hydraulic rod 29 is activated, extending its telescopic end and rotating the push rod 30. The push rod 30, connected to the second push rod 31, pushes the sliding plate 5 to the left on the guide rod 4. The sliding plate 5 moves the mold plate 13. Utilizing the engagement of the connecting block 25 and the second groove 26, the mold plate 13 and the injection plate 23 overlap and adhere tightly. Injection is performed into the mold groove 18 through the injection port 24 on the injection plate 23. Due to the small opening on the air nozzle 20, the injection liquid, due to its own fluidity, will not enter the first pipe 19. After injection is completed and cooled, the telescopic end of the hydraulic rod 29 retracts, causing the sliding plate 5 to move the mold plate 13 back to its original position. The air pump 21 is activated, and air is pumped into the air chamber 17 through the second pipe 22. The airflow passes through the first pipe 19 and exits into the mold groove 18 through the air nozzle 20. Combined with the Teflon anti-stick layer sprayed in the mold groove 18, the airflow blows out the formed bottle cap. The bottle cap falls into the collection tank 27 and passes through the collection tank 28. When the ramp in section 7 slides out, and the mold plate 13 needs to be cleaned and maintained, the electromagnet 8 is energized to attract the iron sheet 11. The iron sheet 11 drives the moving plate 10 to move to the right, so that the limiting block 12 moves into the cavity 7, breaking the engagement between the limiting block 12 and the groove 15. The spring 9 is compressed and generates elastic potential energy. By using the groove 6 to engage with the rib 14, the handle 16 can be pulled to remove the mold plate 13 from the sliding plate 5, making it convenient to clean the mold plate 13 and the mold groove 18 on it. Then, the electromagnet 8 is de-energized, and the elastic potential energy of the spring 9 causes the moving plate 10 to drive the limiting block 12 to reset. During installation, the ramp design on the limiting block 12 allows the rib 14 to slide in the groove 6 and squeeze the limiting block 12 into the cavity 7. When the groove 15 aligns with the limiting block 12, the elastic potential energy of the spring 9 causes the groove 15 to re-engage with the limiting block 12, thus fixing the mold plate 13.
