[0017] 1. The ejection type injection molding device for bottle cap production, when the power assembly is running, can drive the storage wheel to rotate clockwise, so that the pull rope is gradually rolled into the wheel groove of the storage wheel. As the pull rope is rolled, the ejection plate will move downward through the linkage of the fixed plate and the ejection rod.

When the bottle cap is completed, the power assembly will run again, but at this time it drives the storage wheel to rotate counterclockwise, causing the pull rope to gradually loosen, thereby releasing the downward pulling force on the ejection plate. At this time, the elastic force accumulated by the compression spring due to the previous stretching begins to play a role, pulling the fixed plate, and the ejection plate will move upward through the transmission of the ejection rod. This upward movement can eject the newly produced bottle cap from the molding cavity, which is convenient for subsequent collection and processing, and is convenient for large-scale injection molding production of bottle caps, reducing costs.

[0018] 3. The ejection injection molding device for bottle cap production uses a dual-axis motor to drive the first support rod to rotate, which in turn drives the second bevel gear through the first bevel gear, and then drives the second support rod to rotate. Since the storage wheel is fixedly sleeved on the second support rod, it can drive the storage wheel to rotate. Through the rotation of the storage wheel, the drawstring can be wound and released. When the storage wheel rotates clockwise, the drawstring is wound into the wheel groove of the storage wheel, thereby driving the ejector plate to move downward; when the storage wheel rotates counterclockwise, the drawstring gradually loosens, causing the ejector plate to move upward under the elastic force of the compression spring, which simplifies the operation process and improves production efficiency.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1-6 , an ejection type injection molding device for bottle cap production, comprising a fixed mold 1 and a movable mold 9, a first module 2 is fixedly connected to the top of the fixed mold 1, a plurality of molding cavities 3 are arranged on the first module 2, a fixed groove 4 is opened on the side of the first module 2, a power assembly 5 is arranged on the fixed groove 4, and a ejection assembly 6 is connected to the power assembly 5;

[0029] The material ejecting assembly 6 includes a storage wheel 601, which is connected to the material ejecting assembly 6. A pull rope 602 is fixedly wound in the wheel groove of the storage wheel 601. A fixing plate 603 is fixedly connected to the top of the pull rope 602. A compression spring 606 is fixedly connected to the top of the fixing plate 603. The top of the compression spring 606 is fixedly connected to the inner top wall of the fixing groove 4.

[0030] The top of the fixed plate 603 is fixedly connected with a push rod 604, the top of the push rod 604 penetrates the fixed mold 1 and extends to the inside of the molding cavity 3, and the top of the push rod 604 is fixedly connected with a push plate 605. When the power assembly 5 is running, it can drive the storage wheel 601 to rotate clockwise, so that the pull rope 602 is gradually rolled into the wheel groove of the storage wheel 601. As the pull rope 602 is rolled up, the push plate 605 will move downward through the linkage of the fixed plate 603 and the push rod 604. In this process, the compression spring 606 is gradually stretched until the push plate 605 is flush with the molding cavity 3, ensuring the flatness of the molding cavity 3 and providing a good working environment for the subsequent bottle cap injection molding production. When the bottle cap is completed by injection molding, the power assembly 5 will run again, but this time it will drive the storage wheel 601 to rotate counterclockwise, causing the pull rope 602 to gradually loosen, thereby releasing the downward pulling force on the ejector plate 605. At this time, the elastic force accumulated by the compression spring 606 due to the previous stretching begins to play a role, pulling the fixed plate 603. Through the transmission of the ejector rod 604, the ejector plate 605 will move upward. This upward movement can eject the newly produced bottle cap from the molding cavity 3, which is convenient for subsequent collection and processing, and is convenient for large-scale injection molding production of bottle caps, thereby reducing costs.

[0031] The inner bottom wall of the molding cavity 3 is provided with a receiving groove 7, and the ejector plate 605 is located inside the receiving groove 7, and the size of the receiving groove 7 is equal to the size of the ejector plate 605. The bottom of the receiving groove 7 is provided with a through hole 8, and the outer surface of the ejector rod 604 is slidably connected to the inner bottom wall of the through hole 8.

[0032] The power assembly 5 includes a dual-axis motor 501 and two second support rods 504. The bottom of the dual-axis motor 501 is fixedly connected to the inner bottom wall of the fixed groove 4. The output ends on both sides of the dual-axis motor 501 are fixedly connected to the first support rod 502. Both ends of the first support rod 502 are fixedly connected to the first bevel gear 503. The two second support rods 504 are symmetrically rotatably connected to the two sides inside the fixed groove 4. The storage wheel 601 is fixedly sleeved on the outer surface of the second support rod 504. One end of the second support rod 504 is fixedly connected to the second bevel gear 505. The teeth of the second bevel gear 505 are meshed with the teeth of the first bevel gear 503. The operation of the dual-axis motor 501 drives the first support rod 502 to rotate, and drives the second bevel gear 505 through the first bevel gear 503, thereby driving the second support rod 504 to rotate. Since the storage wheel 601 is fixedly sleeved on the second support rod 504, it can drive the storage wheel 601 to rotate. Through the rotation of the storage wheel 601, the winding and releasing operations of the pull rope 602 can be realized. When the storage wheel 601 rotates clockwise, the pull rope 602 is wound into the wheel groove of the storage wheel 601, thereby driving the ejection plate 605 to move downward; when the storage wheel 601 rotates counterclockwise, the pull rope 602 gradually loosens, so that the ejection plate 605 moves upward under the elastic force of the compression spring 606, which simplifies the operation process and improves production efficiency.

[0033] The middle of the bottom of the movable mold 9 is fixedly connected to a second module 10, and the bottom of the second module 10 is fixedly connected to multiple molding blocks 11 at equal intervals, and the multiple molding blocks 11 correspond to the multiple molding cavities 3. Positioning plates 12 are fixedly connected to both sides of the bottom of the movable mold 9, and positioning grooves are provided on both sides of the top of the fixed mold 1, and the positioning plates 12 correspond to the positioning grooves. Positioning rods 13 are fixedly connected to the four corners of the bottom of the movable mold 9, and positioning holes 14 are provided at the four corners of the top of the fixed mold 1, and the positioning rods 13 correspond to the positioning holes 14.

[0034] When in use, the dual-axis motor 501 drives the first support rod 502 to rotate, and drives the second bevel gear 505 through the first bevel gear 503, thereby driving the second support rod 504 to rotate. Since the storage wheel 601 is fixedly sleeved on the second support rod 504, the storage wheel 601 can be driven to rotate;

[0035] When the storage wheel 601 rotates clockwise, the pull rope 602 is gradually rolled into the wheel groove of the storage wheel 601. As the pull rope 602 is rolled up, the ejection plate 605 moves downward through the linkage of the fixed plate 603 and the ejection rod 604. During this process, the compression spring 606 is gradually stretched until the ejection plate 605 is flush with the molding cavity 3, ensuring the flatness of the molding cavity 3 and providing a good working environment for the subsequent bottle cap injection molding production.

[0036] When the bottle cap is completed by injection molding, the power assembly 5 will run again, but this time it will drive the storage wheel 601 to rotate counterclockwise, causing the pull rope 602 to gradually loosen, thereby releasing the downward pulling force on the ejector plate 605. At this time, the elastic force accumulated by the compression spring 606 due to the previous stretching begins to play a role, pulling the fixed plate 603. Through the transmission of the ejector rod 604, the ejector plate 605 will move upward. This upward movement can eject the newly produced bottle cap from the molding cavity 3, which is convenient for subsequent collection and processing, and is convenient for large-scale injection molding production of bottle caps, thereby reducing costs.
