Description

Technical Field

[0001] This invention relates to the field of blow molding technology, and more particularly to a blow-molded container with a high barrier layer and a method thereof. Background Technology

[0002] During blow molding, plastic is placed in a blow molding container, and air is injected into the middle of the plastic. The plastic expands in the mold to form the desired shape.

[0003] In existing blow-molded containers, multiple high-barrier mold covers are separated by lever rotation. The distance between the top and bottom of the multiple high-barrier mold covers is inconsistent, which makes it impossible to quickly disassemble the bottom of the multiple high-barrier mold covers, resulting in low disassembly efficiency. Therefore, there is a need to provide a blow-molded container with a high-barrier layer and its method. Summary of the Invention

[0004] The purpose of this invention is to solve the problem in the prior art where multiple high-barrier mold covers are separated by lever rotation, resulting in inconsistent separation distances between the top and bottom of the multiple high-barrier mold covers, making it impossible to quickly disassemble the bottom of the multiple high-barrier mold covers and causing low disassembly efficiency. Therefore, this invention proposes a blow-molded container with a high-barrier layer and its method.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a blow-molded container with a high-barrier layer and a method thereof, comprising multiple vertical rods and a servo motor fixed in the middle by a support rod, a threaded column fixed at the top of the servo motor, a top plate fixed at the top of the multiple vertical rods, multiple support frames fixed at the bottom of the top plate, a limit plate fixed between two support frames, a straight opening in the top plate, a threaded ring threaded onto the threaded column, a lifting plate fixed on the threaded ring, multiple support rods fixed at the top of the lifting plate, a support frame fixed at the top of the multiple support rods, multiple limit rings nested and fixed on the support frame, a fixed rod movably placed in the straight opening of the top plate, a sliding plate fixed at the bottom of the fixed rod, a sliding port provided in the opening of the sliding plate, multiple connecting rods fixed on the side of the fixed rod, and a high-barrier mold cover fixed on the side of the fixed rod through the connecting rods.

[0006] In a further preferred embodiment, a small bearing is nested and fixed on the protruding column, a threaded rod is movably passed through the middle of the rotating column and the protruding column, and rolling cylinders are threadedly sleeved at both ends of the threaded rod, with multiple rolling balls movably embedded at the ends of the rolling cylinders.

[0007] More preferably, a small bearing is nested and fixed on the protruding column, and a threaded rod is integrally formed at one end of each protruding column. A rolling cylinder is threadedly sleeved at the end of the threaded rod, and multiple rolling balls are movably embedded at the end of the rolling cylinder.

[0008] More preferably, the angle between the upper and lower parts of the sliding opening and the horizontal plane is 45°, the length of the upper part of the sliding opening is half the length of the lower part, and the middle of the sliding opening is perpendicular to the horizontal plane.

[0009] More preferably, the fixing rod is integrally formed with a support plate on the side of the bottom of the middle support frame of the two support frames, and the limiting block, the parallel plate and the support plate are kept parallel to each other.

[0010] More preferably, the support frame passes through the sliding openings of the four sliding plates, with two limiting rings abutting against the sides of the sliding plates respectively, and the four sliding plates surrounding the top of the lifting plate.

[0011] More preferably, the small bearing is nested inside the rolling cylinder, the protruding column is located in the middle of the rolling cylinder, and the rolling ball abuts against the side of the support frame.

[0012] More preferably, the parallel plate is located at the bottom of the limiting block, and the rotating column, protruding column, threaded rod, small bearing and rolling cylinder are axially coaxially arranged, with the rotating column located below the parallel plate.

[0013] A method for blow molding a container with a high barrier layer, characterized in that,

[0014] Step 1: Place the plastic into the middle of four high-barrier mold covers, then inject air into the plastic. The plastic expands outward and adheres to the inner wall of the four high-barrier mold covers. Subsequently, the plastic cools and solidifies to form the desired shape.

[0015] Step 2: The servo motor drives the threaded column to rotate. The threaded column rotates in the middle of the threaded ring, causing the threaded ring, lifting plate, support rod and support frame to move downward. The support frame moves in the sliding port. The limit block abuts against the top of the parallel plate to prevent the fixed rod from rotating and moving horizontally. The support frame opens up the sliding plate, fixed rod, connecting rod and high barrier mold cover.

[0016] Step 3: The support frame moves to the vertical part of the sliding opening, and then the support frame enters the lower part of the sliding opening. The support frame retracts the four sliding plates, causing the high-barrier mold cover, the fixing rod and the sliding plates to rotate around the rotating column. The four high-barrier mold covers tilt and open, and then the plastic of the molding thickness is taken out from the middle of the multiple high-barrier mold covers.

[0017] The beneficial effects of this invention are:

[0018] The support frame moves downwards through the sliding openings of the four sliding plates, opening them up and causing the four high-barrier mold covers to separate synchronously. This ensures that the movement distance of each position of the high-barrier mold cover is consistent with that of the plastic, as shown in the instruction manual. Figure 7 As shown, this allows for rapid separation of the high-barrier mold cover from the plastic at various locations, offering the advantage of quick separation.

[0019] The support frame moves downwards through the sliding openings of the four sliding plates. When the support frame enters the lower part of the sliding opening, it retracts the sliding plates, causing the sliding plates, fixed rods, and high-barrier mold cover to rotate around the rotating column. The high-barrier mold cover tilts, causing its top to quickly separate, as shown in the attached instruction manual. Figure 8 As shown, multiple high-barrier mold covers are separated at equal intervals and then quickly disassembled by levers, which has the advantage of high separation efficiency.

[0020] The limiting block moves at the top of the parallel plate, so that when the support frame is in the upper part of the sliding opening, the limiting block abuts against the top of the parallel plate, preventing the sliding plate, fixed rod, and high-barrier mold cover from rotating during translation. This allows the sliding plate, fixed rod, and high-barrier mold cover to translate and separate. Subsequently, when the support frame enters the lower part of the sliding opening, the limiting block separates from the parallel plate, allowing the sliding plate, fixed rod, and high-barrier mold cover to rotate. The top of the high-barrier mold cover separates quickly. The high-barrier mold cover first translates and then tilts, ensuring that the plastic is evenly stressed at each position when separating from multiple high-barrier mold covers, ensuring the quality of the molded plastic. The high-barrier mold cover is then quickly separated by levers, facilitating the falling of the plastic. Attached Figure Description

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0031] Reference Figures 1 to 8 A blow-molded container with a high barrier layer and its method are disclosed, comprising multiple vertical rods 1 and a servo motor 2 fixed in the middle by a support rod. A threaded column 3 is fixed to the power output end of the servo motor 2. A top plate 4 is fixed to the top of the multiple vertical rods 1. Multiple support frames 5 are fixed to the bottom of the top plate 4. A limit plate 6 is fixed between two support frames 5. A straight opening 17 is provided in the top plate 4. A threaded ring 7 is threaded onto the threaded column 3. A lifting plate 8 is fixed to the threaded ring 7. Multiple support rods 9 are fixed to the top of the lifting plate 8. A support frame 10 is fixed to the top of the multiple support rods 9. Multiple limit rings 11 are nested and fixed on the support frame 10. A fixed rod 13 is movably placed in the straight opening 17 of the top plate 4. A sliding plate 12 is fixed to the bottom of the fixed rod 13. A sliding port 16 is provided in the sliding plate 12. Multiple connecting rods 14 are fixed to the side of the fixed rod 13. A high barrier mold cover 15 is fixed to the side of the fixed rod 13 through the connecting rods 14.

[0032] Preferably, a parallel plate 19 is fixed to the inner side of the support frame 5, and limit blocks 18 are fixed to both sides of the fixing rod 13. A rotating column 20 is movably passed through the fixing rod 13. Both ends of the rotating column 20 are integrally formed with protruding columns 21. Small bearings 23 are nested and fixed on the protruding columns 21. A threaded rod 22 is movably passed through the middle of the rotating column 20 and the protruding columns 21. Rolling cylinders 24 are threadedly connected to both ends of the threaded rod 22. Multiple rolling balls 25 are movably embedded at the ends of the rolling cylinders 24.

[0033] In practice, the limiting block 18 moves at the top of the parallel plate 19, so that when the support frame 10 is in the upper part of the sliding port 16, the limiting block 18 abuts against the top of the parallel plate 19, preventing the sliding plate 12, the fixing rod 13 and the high-barrier mold cover 15 from rotating during translation, so that the sliding plate 12, the fixing rod 13 and the high-barrier mold cover 15 can be separated. Then, when the support frame 10 enters the lower part of the sliding port 16, the limiting block 18 separates from the parallel plate 19, and the sliding plate 12, the fixing rod 13 and the high-barrier mold cover 15 can rotate. The top of the high-barrier mold cover 15 separates quickly. The high-barrier mold cover 15 first translates and then tilts to ensure that the plastic is evenly stressed at each position when it separates from the multiple high-barrier mold covers 15, ensuring the quality of the molded plastic. The high-barrier mold cover 15 is quickly separated by levers to facilitate the falling of the plastic.

[0034] Preferably, the angle between the upper and lower parts of the sliding opening 16 and the horizontal plane is 45°, the length of the upper part of the sliding opening 16 is half the length of the lower part, and the middle of the sliding opening 16 is perpendicular to the horizontal plane.

[0035] In practice, the support frame 10 moves downward within the sliding openings 16 of the four sliding plates 12, thus opening the four sliding plates 12 and causing the four high-barrier mold covers 15 to separate synchronously. This ensures that the movement distance of each position of the high-barrier mold cover 15 is consistent with that of the plastic, as shown in the attached instruction manual. Figure 7 As shown, this allows for rapid separation of the high-barrier mold cover 15 from the plastic at various locations.

[0036] Preferably, the fixing rod 13 is located on the side of the bottom of the middle support frame 5 of the two support frames 5, and the limiting block 18, the parallel plate 19 and the support plate are kept parallel. The support frame 10 passes through the sliding opening 16 of the four sliding plates 12, and the two limiting rings 11 abut against the two sides of the sliding plate 12 respectively. The four sliding plates 12 surround the top of the lifting plate 8.

[0037] In practice, the support frame 10 moves downward through the sliding openings 16 of the four sliding plates 12. When the support frame 10 enters the lower part of the sliding openings 16, it retracts the sliding plates 12, causing the sliding plates 12, the fixing rod 13, and the high-barrier mold cover 15 to rotate around the rotating column 20. The high-barrier mold cover 15 tilts, causing its top to quickly separate as shown in the attached instruction manual. Figure 8 As shown, multiple high-barrier mold covers 15 are separated at equal intervals and then quickly disassembled by levers.

[0038] Preferably, the small bearing 23 is nested inside the rolling cylinder 24, the protruding post 21 is located in the middle of the rolling cylinder 24, the rolling ball 25 abuts against the side of the support frame 5, and the rolling ball 25 abuts against the end of the rolling cylinder 24 to prevent the rolling cylinder 24 from rubbing against the side of the support frame 5. The rolling ball 25 rolls at the end of the rolling cylinder 24, which can reduce friction and make the rolling cylinder 24 roll smoothly on the side of the support frame 5.

[0039] Preferably, the parallel plate 19 is located at the bottom of the limiting block 18, and the rotating column 20, the protruding column 21, the threaded rod 22, the small bearing 23 and the rolling cylinder 24 are arranged coaxially. The rotating column 20 is located below the parallel plate 19, and the protruding column 21 rotates in the middle of the small bearing 23, so that the rolling cylinder 24 rotates well at the end of the rotating column 20. The small bearing 23 reduces friction between the rolling cylinder 24 and the protruding column 21, so that the rolling cylinder 24 rolls on the support plate at the bottom of the support frame 5.

[0040] A method for blow molding a container with a high barrier layer, the first step of which is to place plastic into the middle of four high barrier mold covers 15, then inject air into the plastic, causing the plastic to expand outward and adhere to the inner wall of the four high barrier mold covers 15, and then the plastic cools and solidifies to form the desired shape.

[0041] Step 2: Servo motor 2 drives threaded column 3 to rotate. Threaded column 3 rotates in the middle of threaded ring 7, causing threaded ring 7, lifting plate 8, support rod 9 and support frame 10 to move downward. Support frame 10 moves in sliding port 16. Limit block 18 abuts against the top of parallel plate 19 to prevent fixed rod 13 from rotating and moving horizontally. Support frame 10 opens up sliding plate 12, fixed rod 13, connecting rod 14 and high barrier mold cover 15.

[0042] Step 3: The support frame 10 moves to the vertical part of the sliding port 16, and then the support frame 10 enters the lower part of the sliding port 16. The support frame 10 retracts the four sliding plates 12, so that the high barrier mold cover 15, the fixing rod 13 and the sliding plate 12 rotate around the rotating column 20. The four high barrier mold covers 15 tilt and open, and then the plastic of the molding thickness is taken out from the middle of the multiple high barrier mold covers 15.

[0043] In this invention, during use, firstly, plastic is placed between four high-barrier mold covers 15. Secondly, the servo motor 2 drives the threaded column 3 to rotate. The threaded column 3 rotates in the middle of the threaded ring 7, causing the threaded ring 7 and the lifting plate 9 to move upwards at the end of the threaded column 3. The support frame 10 moves upwards in the sliding opening 16 of the sliding plate 12. The support frame 10 spreads the four sliding plates 12, causing the sliding plates 12, the fixing rod 13, and the high-barrier mold covers 15 to rotate around the rotating column 20. The high-barrier mold covers 15 then retract to maintain parallelism, as per the attached instruction manual. Figure 7As shown, the support frame 10 then continues to move upward in the sliding port 16, the limiting block 18 abuts against the top of the parallel plate 19 in parallel, the support frame 10 retracts the sliding plate 12, the sliding plate 12, the fixing rod 13 and the high-barrier mold cover 15 move horizontally, the four high-barrier mold covers 15 move horizontally synchronously, the four high-barrier mold covers 15 remain parallel during the process of approaching, the four high-barrier mold covers 15 cover the plastic, then air is injected into the plastic, the plastic expands and stretches to stick to the inner wall of the four high-barrier mold covers 15, after the plastic cools and forms the required shape, finally the servo motor 2 drives the threaded column 3 to rotate in the opposite direction, the four high-barrier mold covers 15 separate from the plastic.

[0044] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
