Description

Technical Field

[0001] The present invention relates to the technical field of injection molding equipment, and particularly to an injection molding equipment for nylon zipper production and its working method. Background Technique

[0002] The injection molding equipment for nylon zipper production is mainly an injection molding machine, especially a vertical injection molding machine, which is suitable for the molding of small and precise products, such as zipper heads. This type of injection molding machine can heat plastics, apply high pressure to the molten plastics, and make them inject and fill the mold cavity, thereby producing various components of nylon zippers.

[0003] When the existing nylon zipper injection molding equipment is in use, although it shapes the nylon zipper, the demolding effect of the traditional injection molding equipment is not good, resulting in the situation of sticking to the mold when taking out the injection-molded nylon zipper, and it is not convenient to collect the demolded nylon zipper. As a result, after the nylon zipper is demolded, workers need to manually collect the shaped nylon zipper, which reduces the working efficiency of the equipment. At the same time, the amount of material pouring cannot be controlled, resulting in a large amount of material remaining in the funnel when the conveying device is in use, thus causing blockage to the equipment, and it is not convenient to clean the mold after demolding, resulting in residues remaining when shaping the next group of nylon zippers, thereby reducing the production effect of the equipment. For this reason, an injection molding equipment for nylon zipper production and its working method are introduced. Summary of the Invention

[0014] As a preferred technical solution of the present invention: It includes the following steps: S1: When the injection molding equipment body is performing operations, a signal is sent through the controller, prompting the power output shaft of the double-rotor motor to start rotating after receiving the signal. During the rotation of the power output shaft of the double-rotor motor, it will drive the conveying device to operate, and then the materials inside the storage tank are conveyed out through the conveying device. After the materials are conveyed to the inner wall of the support shell, the support shell guides the materials to move from its inner wall to the inner wall of the funnel. Then, the feed pipe and the material conveying pipe work together to convey the materials on the inner wall of the funnel to the inner wall of the heating device for heating. Finally, after the first hydraulic device receives the signal, it drives the feed pipe, the heating device, and the upper mold to move, so that the upper mold fits tightly with the lower mold, thereby shaping the nylon zipper. S2: When the power output shaft of the double-rotor motor rotates, it will drive the rotating shaft to rotate accordingly, and then prompt the first rotating rod to start rotating. During the rotation of the first rotating rod, it will apply pressure to the first limiting rod and the pressing rod, pushing the screw rod to move along the inner wall of the threaded housing. As the screw rod moves on the inner wall of the threaded housing, it will drive the threaded housing to rotate in the inner wall of the rotating groove. At the same time, the meshing transmission of the gear and the rack ensures that when the threaded housing rotates, it can drive the rack and the connecting block to move on the outer wall of the second limiting rod. During the movement of the rack, it will further push the connecting rod and the baffle, causing the baffle to reciprocate at the material outlet support shell, thereby limiting the materials placed inside the support shell to prevent them from continuously flowing into the inner wall of the funnel. S3: After the nylon zipper is injection molded, the first hydraulic device drives the upper mold to move upward, and at the same time, the second hydraulic device prompts the lower mold to move downward. During the downward movement of the lower mold, it will slide on the outer wall of the sliding rod and further drive the top plate to move downward. When the top plate and the sliding rod are moving, they will apply pressure to the first pushing plate, so that it presses the nylon zipper inside the lower mold, thereby pushing the nylon zipper out of the slot of the lower mold and realizing the demolding of the injection-molded nylon zipper. S4: During the demolding process of the injection-molded nylon zipper, the lower mold moves downward driven by the second hydraulic device, causing the lower mold to drive the connecting plate and the extension plate to move synchronously during the movement. Subsequently, the extension plate guides the rotating plate and the limiting column to rotate along the inner wall of the placement groove. During this process, the rotation of the rotating plate drives the pressing plate to rotate, thereby causing the pressing plate to apply pressure to the second connecting column when rotating. The second connecting column under pressure pushes the sliding block to move inside the fixed rod, and the movement of the sliding block drives the second pushing plate to move. The second pushing plate pushes the demolded nylon zipper during the movement, and while pushing, releases the limit on the second spring and releases its elastic potential energy. The accelerated movement of the second spring further pushes the second pushing plate, thereby pushing the nylon zipper from the outer wall of the inclined plate to the inner wall of the collection box for collection; S5: During the rotation of the power output shaft of the dual-rotor motor, it drives the rotating column to rotate, thereby causing the fan blades to rotate accordingly. When the fan blades rotate, they generate wind, and this wind is transmitted through the inner wall of the first air delivery pipe to the inner wall of the second air delivery pipe. The second air delivery pipe compresses the transmitted wind to ensure that when the wind is delivered to the inner wall of the air outlet, it can more effectively clean the residues remaining on the top of the lower mold.

[0015] The present invention has the following beneficial effects: 1. For the injection molding equipment and its working method for nylon zipper production, when the dual-rotor motor rotates, it drives the rotating shaft and the rotating column to rotate simultaneously. When a set of power output shafts of the dual-rotor motor rotates, it drives the rotating shaft to rotate, causing the rotating shaft to drive the first rotating rod to rotate. When the first rotating rod rotates, it drives the first limiting rod and the pressing rod to apply pressure to the lead screw, causing the lead screw to move inside the threaded housing. When the lead screw moves inside the threaded housing, it drives the threaded housing to rotate inside the rotating groove, and the gear meshes with the rack for transmission, causing the threaded housing to drive the rack and the connecting block to move on the outer wall of the second limiting rod. When the rack moves, it drives the connecting rod and the baffle to move, causing the baffle to reciprocate at the material outlet of the support shell to limit the material placed inside the support shell so that it does not continuously flow into the inner wall of the funnel and cause blockage. Then, the other set of power output shafts of the dual-rotor motor drives the rotating column to rotate, causing the rotating column to drive the fan blades to rotate when rotating. When the fan blades rotate, they generate wind, and the wind generated by the fan blades is transmitted from the inner wall of the first air delivery pipe to the inner wall of the second air delivery pipe. The second air delivery pipe squeezes the transmitted wind, so that when the second air delivery pipe delivers the wind to the inner wall of the air outlet, it can better clean the residues remaining on the top of the lower mold, thereby improving the working efficiency of the injection molding equipment body.

[0016] 2. The injection molding equipment for nylon zipper production and its working method. After the nylon zipper is injection molded, the upper mold is driven upward by the first hydraulic device, and the lower mold is driven downward by the second hydraulic device. When the lower mold moves downward, it moves on the outer wall of the sliding rod and also drives the top plate downward. When the top plate and the sliding rod move, they drive the push plate one to press the nylon zipper inside the lower mold, so that the nylon zipper is removed from the slot of the lower mold to demold the injection-molded nylon zipper. At the same time, when the second hydraulic device drives the lower mold to move downward, the lower mold drives the connecting plate and the extension plate to move when moving. The extension plate drives the rotating plate and the limiting column to rotate on the inner wall of the placement groove. When the rotating plate rotates, it drives the pressure plate to rotate. When the pressure plate rotates, it drives the extension plate to press the connecting column two. After the connecting column two is subjected to pressure, it drives the sliding block to move inside the fixed rod. When the sliding block moves, it drives the push plate two to move. When the push plate two moves, it pushes the nylon zipper on the top of the lower mold after demolding. And when the push plate two pushes the nylon zipper, the limit on the second spring is cancelled, so that the elastic potential energy of the second spring is released. The elastic force of the second spring accelerates to drive the push plate two to push the nylon zipper, and the pushed nylon zipper moves from the outer wall of the inclined plate to the inner wall of the collection box for collection.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

The rotation of the power output shaft of the double-rotor motor 14 drives the operation of the conveying device 13, thereby promoting the conveying device 13 to convey the materials in the storage tank 12. The materials are conveyed by the conveying device 13 to the inner wall of the support shell 15, and the support shell 15 guides the materials to transfer from its inner wall to the inner wall of the funnel 8. Subsequently, the feed pipe 5 and the material conveying pipe 7 cooperate to convey the materials on the inner wall of the funnel 8 to the inner wall of the heating device 18 for heating treatment. After receiving the signal, the hydraulic device 6 drives the feed pipe 5, the heating device 18 and the upper mold 19 to move, so that the upper mold 19 is closely attached to the lower mold 22, and then the heated materials are conveyed to the slots of the upper mold 19 and the lower mold 22 for shaping, thereby injecting the nylon zipper.

[0021] In a preferred embodiment: The blocking component 16 includes a rotating shaft 1601. One end of a rotating rod 1602 is fixedly assembled on the outer wall of the rotating shaft 1601.

When the rotating rod 1602 rotates, it will apply pressure to the limiting rod 1603 and the pressing rod 1604, pushing the lead screw 1605 to move along the inner wall of the threaded housing 1610. As the lead screw 1605 moves along the inner wall of the threaded housing 1610, it will drive the threaded housing 1610 to rotate in the inner wall of the rotating groove 1609. At the same time, the meshing transmission between the gear 1611 and the rack 1612 ensures that when the threaded housing 1610 rotates, it can drive the rack 1612 and the connecting block 1615 to move on the outer wall of the limiting rod 1608. During the movement of the rack 1612, it will further push the connecting rod 1613 and the baffle 1614, causing the baffle 1614 to perform a reciprocating motion at the blanking port support shell 15. This reciprocating motion realizes the limitation of the material inside the support shell 15, thereby reducing the blanking amount of the material and effectively avoiding the blockage phenomenon during the operation of the equipment.

[0022] In a preferred embodiment: The cleaning component 17 includes a rotating column 1701. Blades 1702 are fixedly assembled on the outer wall of the rotating column 1701.

The fan blade 1702 generates wind during rotation, and the wind is transmitted to the inner wall of the second air delivery pipe 1704 through the inner wall of the first air delivery pipe 1703. The second air delivery pipe 1704 compresses the transmitted wind to enhance the wind force, and finally conveys the wind to the inner wall of the air outlet 1705, thereby effectively removing the dirt remaining on the top of the lower mold 22.

During the downward movement of the lower mold 22, it slides on the outer wall of the sliding rod 2313 and drives the top plate 2310 to move downward. When the top plate 2310 and the sliding rod 2313 move, they apply pressure to the first pushing plate 2314, thereby pushing the nylon zipper out of the slot of the lower mold 22 for demolding the injection-molded nylon zipper. When the top plate 2310 continues to move downward, it applies pressure to the installation block 2311, and then the installation block 2311 applies pressure to the second pressure-receiving rod 2309. After the second pressure-receiving rod 2309 is subjected to pressure, it pushes the blocking rod 2308 to apply pressure to the moving block 2307. After the moving block 2307 is subjected to pressure, it slides on the inner wall of the moving groove 2306 and drives the limiting block 2303 to move downward. When the moving block 2307 moves to the end of the moving groove 2306, it applies additional pressure to the second pressure-receiving rod 2309, causing the second pressure-receiving rod 2309 to drive the top plate 2310 to apply pressure to the sliding rod 2313 and causing the first pushing plate 2314 to apply pressure to the nylon zipper inside the lower mold 22, thereby achieving a good demolding effect.

The inner wall of the fixing rod 2410 is slidably connected to a sliding block 2411. The inner wall of the sliding block 2411 is rotatably connected to a second connecting column 2412. The top of the sliding block 241 is fixedly assembled with a second pushing plate 2413. One end of the outer wall of the second pushing plate 2413 is fixedly assembled with one end of a third connecting column 2414. The other end of the third connecting column 2414 is fixedly assembled with a second spring 2415; In the above structure, the lower die 22 is driven by the second hydraulic device 21 to move downward, so that the lower die 22 drives the connecting plate 2401 and the extension plate 2403 to move synchronously during the movement. Subsequently, the extension plate 2403 drives the rotating plate 2404 and the limiting post 2406 to rotate on the inner wall of the placing groove 3. During this process, when the rotating plate 2404 rotates, it will further drive the pressing plate 2407 to rotate, resulting in the pressing plate 2407 applying pressure to the second connecting column 2412 during the rotation. Affected by this pressure, the second connecting column 2412 will push the sliding block 2411 to move on the inner wall of the fixing rod 2410. Furthermore, when the sliding block 2411 moves, it will drive the second pushing plate 2413 to move. The second pushing plate 2413 will push the nylon zipper after demolding on the top of the lower die 22 during the movement, and will release the limit on the second spring 2415 during the pushing process, thereby releasing the elastic potential energy of the second spring 2415. The accelerated movement of the second spring 2415 further pushes the second pushing plate 2413 to push the nylon zipper. The pushed nylon zipper moves from the outer wall of the inclined plate 20 to the inner wall of the collecting box 10 for collection. After the nylon zipper is collected, a signal is sent by the controller 2, so that the second hydraulic device 21 receives the signal and pushes the lower die 22 to move upward. During the upward movement of the lower die 22, it drives the connecting plate 2401 and the extension plate 2403 to move upward synchronously. Furthermore, the extension plate 2403 drives the limiting post 2406, the rotating plate 2404 and the pressing plate 2407 to rotate in the reverse direction. When the pressing plate 2407 rotates in the reverse direction, it will apply pressure to the extension plate 2409, thereby pushing the sliding block 2411 to retract. After the sliding block 2411 retracts, it will drive the second pushing plate 2413 to retract, ensuring that the second pushing plate 2413 moves out from the top of the lower die 22, and preventing the collecting assembly 24 from being damaged during the operation of the equipment.

At the same time, the extension plate 2403 is used to connect the connecting plate 2401, the rotating plate 2404 and the pressing plate 2407, so that when the connecting plate 2401 moves, it will drive the rotating plate 2404 and the pressing plate 2407 to operate. The second spring 2415 is limited by the placement groove 3 and the third connecting column 2414, so that the second spring 2415 will not break away when releasing elastic potential energy. The materials inside the funnel 8 are conveyed through the feed pipe 5 and the conveying pipe 7.

[0029] In a preferred embodiment: The following steps are included: S1: When the injection molding equipment body 1 is performing an operation, a signal is sent through the controller 2, prompting the power output shaft of the double-rotor motor 14 to start rotating after receiving the signal. During the rotation of the power output shaft of the double-rotor motor 14, the conveying device 13 is driven to operate, and then the materials inside the storage tank 12 are conveyed out through the conveying device 13. After the materials are conveyed to the inner wall of the support shell 15, the support shell 15 guides the materials to move from its inner wall to the inner wall of the funnel 8. Then, the feed pipe 5 and the conveying pipe 7 work together to convey the materials on the inner wall of the funnel 8 to the inner wall of the heating device 18 for heating. Finally, after receiving the signal, the first hydraulic device 6 drives the feed pipe 5, the heating device 18 and the upper mold 19 to move, so that the upper mold 19 is closely attached to the lower mold 22, thereby shaping the nylon zipper; S2: When the power output shaft of the dual-rotor motor 14 rotates, it drives the rotating shaft 1601 to rotate accordingly, and then causes the first rotating rod 1602 to start rotating. During the rotation of the first rotating rod 1602, it applies pressure to the first limiting rod 1603 and the pressing rod 1604, pushing the lead screw 1605 to move along the inner wall of the threaded housing 1610. As the lead screw 1605 moves along the inner wall of the threaded housing 1610, it drives the threaded housing 1610 to rotate within the inner wall of the rotating groove 1609. At the same time, the meshing transmission between the gear 1611 and the rack 1612 ensures that when the threaded housing 1610 rotates, it can drive the rack 1612 and the connecting block 1615 to move on the outer wall of the second limiting rod 1608. During the movement of the rack 1612, it further pushes the connecting rod 1613 and the baffle 1614, causing the baffle 1614 to perform reciprocating motion at the material discharge port support housing 15, thereby limiting the material placed inside the support housing 15 to prevent it from continuously flowing into the inner wall of the funnel 8; S3: After the nylon zipper is injection-molded, the hydraulic device one 6 drives the upper mold 19 to move upward, and at the same time, the hydraulic device two 21 causes the lower mold 22 to move downward. During the downward movement of the lower mold 22, it slides on the outer wall of the sliding rod 2313 and further drives the top plate 2310 to move downward. When the top plate 2310 and the sliding rod 2313 move, they apply pressure to the first pushing plate 2314, causing it to apply pressure to the nylon zipper inside the lower mold 22, thereby pushing the nylon zipper out of the slot of the lower mold 22 to achieve the demolding of the injection-molded nylon zipper; S4: During the demolding process of the injection-molded nylon zipper, the hydraulic device two 21 drives the lower mold 22 to move downward, causing the lower mold 22 to drive the connecting plate 2401 and the extension plate 2403 to move synchronously during the movement. Subsequently, the extension plate 2403 guides the rotating plate 2404 and the limiting column 2406 to rotate along the inner wall of the placement groove 3. During this process, the rotation of the rotating plate 2404 drives the pressure-applying plate 2407 to rotate, and then causes the pressure-applying plate 2407 to apply pressure to the second connecting column 2412 when rotating. The second connecting column 2412 under pressure pushes the sliding block 2411 to move within the inner wall of the fixed rod 2410, and the movement of the sliding block 2411 drives the second pushing plate 2413 to move. The second pushing plate 2413 pushes the demolded nylon zipper during the movement and releases the elastic potential energy of the second spring 2415 by removing the limit on it while pushing. The accelerated movement of the second spring 2415 further pushes the second pushing plate 2413, thereby pushing the nylon zipper from the outer wall of the inclined plate 20 to the inner wall of the collection box 10 for collection; S5: During the rotation of the power output shaft of the dual-rotor motor 14, the rotating column 1701 is driven to rotate, thereby causing the fan blade 1702 to rotate accordingly. When the fan blade 1702 rotates, wind is generated. This wind is transmitted through the inner wall of the first air delivery pipe 1703 to the inner wall of the second air delivery pipe 1704. The second air delivery pipe 1704 compresses the transmitted wind to ensure that when the wind is delivered to the inner wall of the air outlet 1705, the residue remaining on the top of the lower mold 22 can be cleaned more effectively.

10. The working method of an injection molding device for nylon zipper production according to claim 9, characterized in that: It includes the following steps: S1: When the injection molding equipment body (1) is performing operations, a signal is sent through the controller (2), prompting the power output shaft of the dual-rotor motor (14) to start rotating after receiving the signal. During the rotation of the power output shaft of the dual-rotor motor (14), it drives the operation of the delivery device (13). Then, the material inside the storage tank (12) is delivered through the delivery device (13). After the material is delivered to the inner wall of the support shell (15), the support shell (15) guides the material to move from its inner wall to the inner wall of the funnel (8). Then, the feed pipe (5) and the material delivery pipe (7) work together to deliver the material on the inner wall of the funnel (8) to the inner wall of the heating device (18) for heating. Finally, after the first hydraulic device (6) receives the signal, it drives the feed pipe (5), the heating device (18) and the upper mold (19) to move, so that the upper mold (19) is closely attached to the lower mold (22), thereby shaping the nylon zipper. S2: When the power output shaft of the dual-rotor motor (14) rotates, it drives the rotating shaft (1601) to rotate accordingly, and then causes the first rotating rod (1602) to start rotating. During the rotation of the first rotating rod (1602), it exerts pressure on the first limiting rod (1603) and the pressing rod (1604), pushing the lead screw (1605) to move along the inner wall of the threaded housing (1610). As the lead screw (1605) moves on the inner wall of the threaded housing (1610), it drives the threaded housing (1610) to rotate within the inner wall of the rotating groove (1609). At the same time, the meshing transmission between the gear (1611) and the rack (1612) ensures that when the threaded housing (1610) rotates, it can drive the rack (1612) and the connecting block (1615) to move on the outer wall of the second limiting rod (1608). During the movement of the rack (1612), it further pushes the connecting rod (1613) and the baffle (1614), causing the baffle (1614) to perform reciprocating motion at the material discharge port support housing (15), thereby limiting the material placed inside the support housing (15) and preventing it from continuously flowing into the inner wall of the funnel (8); S3: After the nylon zipper is injection-molded, the hydraulic device one (6) drives the upper mold (19) to move upward, and at the same time, the hydraulic device two (21) causes the lower mold (22) to move downward. During the downward movement of the lower mold (22), it slides on the outer wall of the sliding rod (2313) and further drives the top plate (2310) to move downward. When the top plate (2310) and the sliding rod (2313) move, they exert pressure on the first pushing plate (2314), causing it to exert pressure on the nylon zipper inside the lower mold (22), thereby pushing the nylon zipper out of the slot of the lower mold (22) and realizing the demolding of the injection-molded nylon zipper; S4: During the demolding process of the injection-molded nylon zipper, the hydraulic device two (21) drives the lower mold (22) to move downward, causing the lower mold (22) to drive the connecting plate (2401) and the extension plate (2403) to move synchronously during the movement. Subsequently, the extension plate (2403) guides the rotating plate (2404) and the limiting column (2406) to rotate along the inner wall of the placement groove (3). During this process, the rotation of the rotating plate (2404) drives the pressure-applying plate (2407) to rotate, and further causes the pressure-applying plate (2407) to exert pressure on the second connecting column (2412) when rotating. The second connecting column (2412) under pressure pushes the sliding block (2411) to move inside the fixed rod (2410), and the movement of the sliding block (2411) drives the second pushing plate (2413) to move. The second pushing plate (2413) pushes the demolded nylon zipper during the movement and releases the elastic potential energy of the second spring (2415) by removing the limit on it at the same time. The accelerated movement of the second spring (2415) further pushes the second pushing plate (2413), thereby pushing the nylon zipper from the outer wall of the inclined plate (20) to the inner wall of the collection box (10) for collection; S5: During the rotation of the power output shaft of the dual-rotor motor (14), the rotating column (1701) will be driven to rotate, which in turn causes the fan blade (1702) to rotate accordingly. When the fan blade (1702) rotates, wind power is generated. This wind power is transmitted through the inner wall of the first air delivery pipe (1703) to the inner wall of the second air delivery pipe (1704). The second air delivery pipe (1704) compresses the transmitted wind to ensure that when the wind is delivered to the inner wall of the air outlet (1705), the residue remaining on the top of the lower mold (22) can be cleaned more effectively.
