Description

Technical Field

[0001] The utility model relates to the technical field of plastic bottle cap processing, in particular to an injection molding device for processing plastic bottle caps. Background Art

[0002] Bottle caps are used to seal bottles. Depending on their functions, there are bottle caps of different shapes and different operating methods. For example, mineral water bottle caps are round and are screwed on, can bottle caps are ring-shaped and are pulled on, and canned meat bottle caps have no fixed shape. Bottle caps are an important part of food and beverage packaging, and are also the first place where consumers come into contact with the product. When producing plastic caps, the commonly used process is injection molding, and injection molding equipment is used.

[0003] After the existing injection molds are stacked on each other, the injection pipe can feed the material into the mold cavity, allowing the hot melt to cool and form. The molding material can be automatically removed or manually removed after the mold is separated. However, due to the high temperature, some molding materials are prone to sticking and adsorbing to the inside of the mold, making subsequent material removal inconvenient and affecting efficiency. For this reason, we propose an injection molding equipment for plastic bottle cap processing. Utility Model Content

[0006] Preferably, when the left mold is docked with the right mold through the docking groove, the molding cavity inside the left mold cooperates with the molding seat on one side of the right mold to form an injection cavity.

[0007] Preferably, a linkage piece is provided inside the built-in groove, and the driving rod and the ejecting rod are fixedly connected and matched through the linkage piece. A support spring connected to the linkage piece is provided inside the built-in groove.

[0008] Preferably, when the left mold is docked and assembled with the right mold, the driving rod is located inside the built-in groove in a telescopic storage state under the extrusion of the left mold, and the same applies to the ejecting rod and the driving rod.

[0010] The utility model provides an injection molding device for processing plastic bottle caps. It has the following beneficial effects:

[0011] 1. An injection molding device for processing plastic bottle caps. In this article, after the left mold is driven by an external feeding device to dock with the right mold, the molding cavity inside the left mold and the molding seat on one side of the right mold form an injection molding cavity. At this time, after the injection tube feeds the material in the external injection molding device, the hot melt material can be introduced into the molding cavity for injection molding. When the left mold first contacts and docks with the right mold, the driving rod inside the first limiting hole will extend and retract into the built-in groove under the extrusion of the left mold. At the same time, the driving rod can drive the ejecting rod to move accordingly through the linkage part, so that the ejecting rod is retracted into the built-in groove. After the injection molding, when the left mold is separated from the right mold, the ejecting rod can be reset and rebounded by the support spring on one side of the linkage part. At this time, the ejecting rod can automatically eject the bottle cap formed outside the molding seat when it pops out, thereby achieving the effect of improving the material taking efficiency.

[0012] 2. This is an injection molding device for processing plastic bottle caps. The molding cavities are located on the surface of the docking groove and are distributed in batches at equal intervals. After the left mold is docked with the right mold, multiple groups of molding seats can adapt to and correspond to multiple groups of molding cavities. In this way, when the multiple groups of injection molding tubes are feeding, the bottle caps can be batch injection molded, thereby achieving the effect of improving the bottle cap processing efficiency.

The interior of the molding seat 4 is penetrated by an injection tube 6 for feeding, and the other end of the injection tube 6 penetrates the interior of the right mold 2 and is connected with the external feeding equipment. The interior of the right mold 2 is provided with a built-in groove 7, and one side of the right mold 2 is provided with a first limiting hole 8 penetrating the built-in groove 7. The end of the molding seat 4 is provided with a second limiting hole 9 penetrating the built-in groove 7. The interior of the first limiting hole 8 is slidingly provided with a driving rod 10, and the interior of the second limiting hole 9 is slidingly provided with a ejecting rod 11 for ejecting the molding cover. The interior of the built-in groove 7 is provided with a linkage part 12, and the driving rod 10 and the ejecting rod 11 are fixedly connected and cooperated by the linkage part 12. The interior of the built-in groove 7 is provided with a support spring 13 supported and connected to the linkage part 12.

[0023] Furthermore, when the left mold 1 is docked with the right mold 2 through the docking groove 3 , the molding cavity 5 inside the left mold 1 cooperates with the molding seat 4 on one side of the right mold 2 to form an injection cavity.

[0024] Furthermore, when the left mold 1 is docked and assembled with the right mold 2 , the driving rod 10 is located inside the built-in groove 7 in a telescopic storage state under the extrusion of the left mold 1 , and the ejecting rod 11 is in the same manner as the driving rod 10 .

[0026] The working principle of this utility model:

[0027] After the left mold 1 is driven by an external feeding device to dock with the right mold 2, the molding cavity 5 inside the left mold 1 and the molding seat 4 on one side of the right mold 2 form an injection cavity. At this time, after the injection tube 6 is fed by the external injection molding device, the hot melt can be introduced into the molding cavity 5 for injection molding. When the left mold 1 first contacts and docks with the right mold 2, the driving rod 10 inside the first limiting hole 8 will be extended and retracted into the built-in groove 7 under the extrusion of the left mold 1. At the same time, the driving rod 10 can drive the ejector rod 11 to move accordingly through the linkage 12, so that the ejector rod 11 is retracted. In the built-in groove 7, after the plastic is injected and molded, when the left mold 1 and the right mold 2 are separated, the ejector rod 11 can be reset and rebounded through the support spring 13 on one side of the linkage part 12. At this time, the ejector rod 11 can automatically eject the bottle cap formed on the outside of the molding seat 4 when it pops out, thereby improving the material taking efficiency. The molding cavity 5 is located on the surface of the docking groove 3 and is distributed in batches and equidistantly. After the left mold 1 is docked with the right mold 2, multiple groups of molding seats 4 can adapt to and correspond to multiple groups of molding cavities 5. In this way, the multiple groups of injection molding tubes 6 can perform batch injection molding on the bottle caps when feeding.
