[0002] Water cups are common drinking tools in people's daily lives. They are lightweight, low-cost, and suitable for various occasions. Water cups are manufactured using injection molding molds, which are molds used for plastic injection molding. Injection molding can mold complex shapes, highly precise dimensions, or plastic products with inserts in a single process. Injection molding is a molding method with advantages including fast production speed, high efficiency, and automated operation. It can produce products with a wide variety of colors, complex shapes, and sizes with precise dimensions. Specifically, it involves injecting molten plastic under high pressure into a mold cavity using an injection molding machine, which then cools and solidifies to obtain a cup. However, currently, when using injection molding molds, the cup cannot be quickly removed from the mold after injection molding; workers need to manually remove the cup from the mold, resulting in low work efficiency.

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0019] like Figure 1-3 As shown, a water cup injection molding mold includes a worktable 1. Support columns 101 are fixedly installed on the upper surface of the worktable 1 near the four corners. A rectangular top plate 2 is fixedly installed on the upper surface of the support columns 101. Electric cylinders 3 are fixedly installed on the lower surface of the rectangular top plate 2 near both ends. An upper mold 301 is fixedly installed at the output end of the electric cylinder 3. A feed nozzle 302 is installed on the upper surface of the upper mold 301. A lower mold 4 is fixedly installed on the upper surface of the worktable 1. A demolding structure 5 is provided inside the worktable 1.
[0020] The demolding structure 5 includes a protective cover 501, a servo motor 502, a transmission rod 503, a first bearing 504, a first bevel gear 505, a rectangular groove 506, a second bevel gear 507, a second bearing 508, a threaded rod 509, a first groove 510, a rectangular slider 511, a lifting column 512, a rectangular slide 513, a rectangular hole 514, a circular groove 515, and a circular top plate 516; a rectangular groove 506 is provided inside the worktable 1, and a first bearing 504 is fixedly installed on the front surface of the rectangular groove 506. A transmission rod 503 is movably mounted on the inner surface of bearing 504; a protective cover 501 is fixedly mounted on the front surface of the worktable 1, and a servo motor 502 is fixedly mounted inside the protective cover 501. The rotating part of the servo motor 502 is fixedly connected to the transmission rod 503; a first bevel gear 505 is fixedly mounted on the rear surface of the transmission rod 503; a second bearing 508 is fixedly mounted in the middle of the upper surface of the rectangular groove 506, and a threaded rod 509 is movably mounted on the inner surface of the second bearing 508; the threaded rod 509... A second bevel gear 507 is fixedly installed at the lower end of the 9th column, which meshes with a first bevel gear 505. A lifting column 512 is threaded onto the outer surface of the threaded rod 509. A first groove 510 is opened in the middle of the upper surface of the worktable 1. Rectangular sliding grooves 513 are opened on both ends of the first groove 510. A rectangular slider 511 is slidably installed on the inner surface of the rectangular sliding groove 513. Rectangular sliders 511 are fixedly installed at the lower ends of both ends of the lifting column 512. A circular dome is fixedly installed on the upper surface of the lifting column 512. Plate 516 and lower mold 4 have a rectangular hole 514 in the middle of their lower surface and a circular groove 515 on their inner bottom surface. When demolding is required after injection molding, the servo motor 502 inside the protective cover 501 is activated, causing the lifting column 512 to drive the rectangular sliders 511 fixedly mounted at the lower ends of both ends to slide upwards within the rectangular groove 513. This causes the lifting column 512 to move the circular top plate 516 fixedly mounted on the upper surface upwards, ejecting the water cup from the lower mold 4, thus improving work efficiency. The electric cylinder 3 and servo motor 502 are electrically connected to an external power supply via corresponding control switches. Both the electric cylinder 3 and servo motor 502 are existing technologies; their specific structures, working principles, and electrical connections are not detailed here.
[0021] It should be noted that this utility model is a water cup injection molding mold. When demolding is required after injection molding, the servo motor 502 inside the protective cover 501 is activated, causing the rotating part of the servo motor 502 to drive the transmission rod 503 to rotate on the inner surface of the first bearing 504. This, in turn, drives the first bevel gear 505 fixedly installed on the rear surface of the transmission rod 503 to rotate. Because the first bevel gear 505 meshes with the second bevel gear 507, it drives the threaded rod 509 to rotate on the inner surface of the second bearing 508. This causes the lifting column 512 threaded on the outer surface of the threaded rod 509 to drive the rectangular slider 511 fixedly installed at the lower ends of both ends to slide upward in the rectangular slide groove 513. This causes the lifting column 512 to drive the circular top plate 516 fixedly installed on the upper surface to move upward, thus ejecting the water cup from the lower mold 4 and improving work efficiency.
