Description

Technical Field

[0001] The present application relates to the field of injection molds, and in particular to a mold for efficiently producing plastic cups. Background Art

[0002] Injection molds are tools used to produce plastic products and give them precise structure and dimensions. Injection molding is a process used for mass production of complex parts. Specifically, the process involves injecting heated, molten plastic into a mold cavity under high pressure using an injection molding machine. After cooling and solidification, the resulting molded product is formed.

[0003] For example, the utility model patent with authorization announcement number CN215703389U discloses a plastic cup injection mold, including a base, four guide rods fixedly connected to the top outer wall of the base, the outer walls of the four guide rods are slidably connected to the same horizontal plate, the bottom outer wall of the horizontal plate is fixedly connected to a collection tray, the bottom end of the collection tray is fixedly connected to two injection pipes, the top outer wall of the base is provided with a first injection cavity and a second injection cavity, and the two injection pipes are respectively located directly above the first injection cavity and the second injection cavity, the top ends of the four guide rods are fixedly connected to the same top plate, and the top outer wall of the top plate is fixedly connected to a storage box and a pumping pump. The utility model is provided with a first injection cavity, a second injection cavity, a collection tray and two injection pipes, and an appropriate amount of injection material is injected into the storage box. The pumping pump is started to transport the material to the collection tray through the feed pipe and the guide hose, and then the hydraulic cylinder is started to push the horizontal plate downward, and the horizontal plate drives the collection tray and the injection pipe to move downward.

[0004] The above-mentioned plastic cup injection mold can simultaneously inject plastic cups of different specifications with high efficiency. However, when it is necessary to inject plastic cups of other specifications, the shapes of the first injection cavity and the second injection cavity need to be changed to produce the corresponding plastic cups. Therefore, the base needs to be replaced. Replacing the base requires disassembling and installing the guide rod, cross plate and corresponding injection equipment at the same time, which is rather troublesome and needs to be improved. Utility Model Content

[0024] By adopting the above technical solution, when installing the upper mold base, align the mounting holes on the upper mold base with the support columns. When the four support columns are all accommodated in the mounting holes and pressed against the hole walls of the mounting holes, the upper mold base is supported on the support columns, and the installation is completed. At this time, the first groove block and the second groove block are accommodated on the corresponding limit seats, and the injection channel is located above the receiving groove.
