Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of injection molding machines, and particularly relates to an injection mold for a PE nozzle cover. Background Art
[0002] The PE nozzle cover is a lid widely used on various packaging containers. Its core material is polyethylene (PE). With its own characteristics and practical design, it occupies an important position in the packaging field. From the perspective of material characteristics, PE is a common thermoplastic plastic with good flexibility, chemical stability, and processing performance. The nozzle cover made of it is relatively soft in texture, easy to operate when opening and closing, and not prone to breakage or damage. At the same time, the PE material has stable chemical properties and has a certain tolerance to most chemical substances such as acids, alkalis, and salts, which can effectively protect the items in the container from being eroded by external chemical substances and ensure the quality and safety of the items.
[0003] Currently, the production of PE nozzle covers is completed by injection molding using an injection molding machine. In order to facilitate the collection work, a collection box is placed at the end face of the inclined plate. After the PE nozzle covers fall from the mold, they fall into the discharge cavity and then are guided into the collection box through the inclined plate in the discharge cavity. However, when the collection box is full of PE nozzle covers, the PE nozzle covers will fall to the ground, causing pollution and damage to the PE nozzle covers. Summary of the Invention

Detailed implementation mode
[0032] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below with reference to the accompanying drawings and embodiments.
[0033] As Figures 1-8 shown, an injection mold for a PE nozzle cover of the present invention includes a machine body 1. A working box 11 is provided on the upper side of the machine body 1. A moving mold 12 and a fixed mold 13 are provided in the working box 11. A driving mechanism extending into the working box 11 and connected to the moving mold 12 is provided on the left side of the machine body 1. An injection mechanism 14 connected to the fixed mold 13 is provided on the right side of the machine body 1. A discharge cavity 2 communicating with the inside of the working box 11 is provided on the front surface of the machine body 1. An inclined plate 21 is provided below the discharge cavity 2. A mounting plate 22 is provided on one side of the inclined plate 21 facing the opening of the discharge cavity 2. The upper surface of the mounting plate 22 is flush with the upper surface of the inclined plate 21. A collection box 23 matching the position of the mounting plate 22 is provided on the front side of the machine body 1. An upward-opening mounting groove 24 is provided above the mounting plate 22. A support plate 25 sliding up and down is provided in the mounting groove 24. The support plate 25 is provided with a triggering mechanism connected to the collection box 23.
[0034] The staff places the collection box 23 in front of the discharge cavity 2 and matching the position of the mounting plate 22. When the driving mechanism starts to work, it pushes the moving mold 12 to slide towards the fixed mold 13 until the moving mold 12 and the fixed mold 13 are completely buckled. At this time, the injection mechanism 14 injects plastic solution between the moving mold 13 and the fixed mold 12, and cools and forms between the moving mold 13 and the fixed mold 12. When the PE nozzle cover is cooled and formed, the moving mold 13 is separated from the fixed mold 12 under the action of the driving mechanism. At this time, the PE nozzle cover is separated from the moving mold 13. The PE nozzle cover falls downward under the action of gravity, and the PE nozzle cover falls on the upper surface of the inclined plate 21. The PE nozzle cover slides downward along the inclined surface of the inclined plate 21 until the PE nozzle cover passes through the mounting plate 22 and falls into the collection box 23;
[0035] When it is necessary to replace the collection box 23, after separating the collection box 23 filled with PE nozzle caps from the machine body 1, since the collection box 23 is separated from the machine body 1, the trigger mechanism drives the support plate 25 to move upward and extend out of the installation groove 24. Therefore, after the collection box 23 is separated from the machine body 1, the support plate 25 extends upward out of the installation groove 24 to block the lower end face of the inclined plate 21. With such a design, after the support plate 25 blocks, the PE nozzle caps will accumulate on the upper end face of the inclined plate 21 under the blocking action of the support plate 25. With such a design, when there is no collection box 23 on the front side of the machine body 1, the PE nozzle caps will remain in the discharge cavity 2 and will not fall to the ground. When there is again a collection box 23 located on the front side of the machine body 1 and the collection box 23 is in a position matching that of the inclined plate 21, under the action of the trigger mechanism, the support plate 25 is driven to move downward again and fall into the installation groove 24, and the PE nozzle caps on the inclined plate 21 will fall into the new collection box 23.
[0036] The trigger mechanism includes a magnetic push plate 3 slidably assembled back and forth under the mounting plate 22. A first magnet block 31 with a magnetic polarity opposite to that of the magnetic push plate 3 is provided on the outer surface of the collection box 23. A connecting line 32 is provided on the lower side of the support plate 25. The lower side of the connecting line 32 passes through the mounting plate 22 and is connected to the magnetic push plate 3. Limiting grooves 321 are provided on the inner walls of both sides of the installation groove 24. Limiting rods 322 are provided in both of the two limiting grooves 321. Limiting blocks 323 sleeved on the outer surfaces of the limiting rods 322 are provided at both ends of the support plate 25. A first spring 324 sleeved on the outer surface of the limiting rod 322 is provided under the limiting block 323.
[0037] When the collection box 23 is located on the front side of the machine body 1 and is in a position matching that of the mounting plate 22 and the inclined plate 21, the position of the first magnet block 31 on the outer surface of the collection box 23 matches the position of the magnetic push plate 3. Since the first magnet block 31 and the magnetic push plate 3 have opposite magnetic polarities, the magnetic push plate 3 is thus pushed to move inward into the discharge cavity 2. The magnetic push plate 3 drives the support plate 25 to move downward in the installation groove 24 through the connecting line 32 and drives the first spring 324 to be compressed downward. The support plate 25 drives the limiting block 323 to move downward relative to the limiting rod 322. When the position of the collection box 23 is separated from the position of the machine body 1, the position of the first magnet block 31 is staggered from the position of the magnetic push plate 3. At this time, under the action of the stretching of the first springs 324 on both sides, the limiting block 323 is driven to move upward, thereby driving the support plate 25 to move upward and reset in the installation groove 24. The support plate 25 drives the magnetic push plate 3 to reset in position under the drive of the connecting line 32.
[0038] On both the left and right sides of the magnetic push plate 3, there are sliding rods 33. The left and right sides of the magnetic push plate 3 are sleeved on the outer surface of the sliding rods 33 on the same side. One end of the sliding rod 33 is connected to the inner wall of the discharge cavity 2, and a stop block 34 is provided at one end of the sliding rod 33 facing the collection box 23. The magnetic push plate 3 can slide relative to the outer surface of the sliding rod 33, and the sliding rod 33 can limit the magnetic push plate 3 to ensure the stability of the sliding of the magnetic push plate 3. The design of the stop block 34 can prevent the magnetic push plate 3 from detaching from the sliding rod 33.
[0039] Below the mounting plate 22, there is a wire wheel 35 that matches the connecting wire 32. The design of the wire wheel 35 can guide the connecting wire 32.
[0040] Inside the support plate 25, there is an inner cavity 4. A sliding part 41 is slidably assembled in the front and back of the inner cavity 4. A through groove 42 is provided on the upper inner wall of the inner cavity 4. Above the sliding part 41, there is a connecting part 43 passing through the through groove 42, and several shunt parts 44 are provided above the connecting part 43.
[0041] The design of several shunt parts 44 can shunt the PE nozzle caps sliding down on the upper surface of the inclined plate 21, preventing the PE nozzle caps from falling from the inclined plate 21 only from one position and accumulating at one position in the collection box 23, and preventing the PE nozzle caps from accumulating and overflowing from one position in the collection box 23 and falling on the ground. Therefore, several shunt parts 44 can shunt the PE nozzle caps to evenly fall into the collection box 23. When the sliding part 41 slides in the inner cavity 4, it can drive several shunt parts 44 to start sliding through the connecting part 43, and the shunt parts 44 start to slide above the mounting plate 22, which can further guide the shunt parts 44 to shunt the PE nozzle caps.
[0042] In the inner cavity 4, there is a limiting rod 45. The sliding part 41 is sleeved on the outer surface of the limiting rod 45. On the left side of the sliding part 41, there is a second spring 46 sleeved on the outer surface of the limiting rod 45. At one end of the sliding part 41 away from the second spring 46, there is a second magnet block 47, and on the inner wall of the inner cavity 4, there is an electromagnet 48 with a magnetic polarity opposite to that of the second magnet block 47.
[0043] When the electromagnet 48 starts to work, it generates magnetism. Since the magnetism generated by the electromagnet 48 is opposite to that of the second magnet block 47, after the electromagnet 48 starts to work, it pushes the second magnet block 47 to start moving away from the electromagnet 48. Therefore, it can drive the sliding part 41 to start moving, and the sliding part 41 drives several shunt parts 44 to start moving, and the second spring 46 starts to compress. When the electromagnet 48 stops working, under the action of the extension of the second spring 46, it drives the sliding part 41 to slide back to its original position, and the sliding part 41 drives several shunt parts 44 to slide back to their original positions. Therefore, when the electromagnet 48 works intermittently, it can drive several shunt parts 44 to start sliding, further improving the shunting effect on the PE nozzle caps.
[0044] A notch 5 is provided on the lower side of the machine body 1. A fixing block 51 that can extend into the notch 5 is provided on the outer surface of the collection box 23. A stepped hole 52 is provided on the inner wall of the notch 5. A third spring 53 is provided in the stepped hole 52. One end of the third spring 53 is provided with a T-shaped locking member 54 that can extend out of the stepped hole 52. A locking hole 55 that matches the T-shaped locking member 54 is provided on the outer surface of the fixing block 51.
[0045] When the position of the collection box 23 matches the position of the mounting plate 22, the fixing block 51 is located in the notch 5. Under the action of the expansion of the third spring 53, the T-shaped locking member 54 is kept locked in the locking hole 55, and the fixing block 51 can be limited. Therefore, the collection box 23 can be fixed on the outside of the machine body 1 and will not move easily. When it is necessary to separate the collection box 23 from the machine body 1, the staff pulls the T-shaped locking member 54 into the stepped hole 52, driving the third spring 53 to be compressed until the T-shaped locking member 54 moves out of the locking hole 55. Therefore, the limit on the fixing block 51 can be cancelled, ensuring that the collection box 23 is separated from the machine body 1. When it is necessary to connect a new collection box 23 to the machine body 1, similarly, the T-shaped locking member 54 can be pulled into the stepped hole 52. After the fixing block 51 extends into the notch 5, the pulling on the T-shaped locking member 54 is released. Under the action of the expansion of the third spring 53, the T-shaped locking member 54 is driven to extend out of the stepped hole 52 and locked in the locking hole 55, completing the limit on the fixing block 51.
[0046] A sliding groove 6 is provided on one side of the machine body 1. A slider 61 is slidably assembled left and right in the sliding groove 6. A connecting hole 62 is provided between the inner wall of the sliding groove 6 and the stepped hole 52. A pull wire 63 is provided on the outer surface of the slider 61. One end of the pull wire 63 passes through the connecting hole 62 and is connected to the T-shaped locking member 54.
[0047] When the staff slides the slider 61 to one side, the T-shaped locking member 54 is pulled into the stepped hole 52 through the pull wire 63. After releasing the slider 61, the pulling on the T-shaped locking member 54 is cancelled.
[0048] A pulling block 64 is provided on the outside of the slider 61. The design of the pulling block 64 facilitates the staff to pull the slider 61.

Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present invention should still be covered by the claims of the present invention.
