[0027] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0028] The embodiment provides a technical solution:

[0029] Please refer to Figures 1-6As shown, the injection mold facilitating waste cleaning includes a lower mold assembly 1, the lower mold assembly 1 includes a base 10, a sliding groove 100 is arranged at the base 10, a notch 102 is arranged at the front side wall of the sliding groove 100; the front side of the notch 102 is fixedly connected with a hollow shell 12; a movable plate 13 is slidingly arranged at the sliding groove 100, a collecting groove 130 for collecting waste is arranged at one side of the top of the movable plate 13, a plurality of gear grooves 131 are arranged at the front end face of the movable plate 13; a gear 15 is rotatably arranged in the inner cavity of the shell 12, the gear 15 is engaged with the gear groove 131, a motor 16 for driving the gear 15 to rotate is arranged at the top of the shell 12; the top of the base 10 is fixedly connected with a lower mold base 11, a plurality of mold cavities 110 are arranged at the top of the lower mold base 11 and are communicated with the sliding groove 100; an upper mold assembly 2 is arranged above the lower mold assembly 1, the upper mold assembly 2 includes a top base 20, the bottom of the top base 20 is fixedly connected with an upper mold base 21, a plurality of male molds 22 are fixedly arranged at the bottom of the upper mold base 21, an injection runner 220 is arranged at each male mold 22 and penetrates the top base 20.

[0030] In the embodiment, the rear side wall of the sliding groove 100 is fixedly connected with a guide rail 101, and the rear end face of the movable plate 13 is provided with a guide groove 132 slidingly connected with the guide rail 101. The arrangement of the guide rail 101 and the guide groove 132 increases the stability and smoothness of the horizontal movement of the movable plate 13, and ensures the stable use of the movable plate 13.

[0031] In the embodiment, the cross-sectional shape of the collecting groove 130 is rectangular, and the depth of the collecting groove 130 is 2-4 cm. The preferred depth of the collecting groove 130 is 3 cm, which facilitates the collection of waste falling in the mold cavity 110 through the collecting groove 130.

[0032] In the embodiment, the left and right ends of the movable plate 13 are fixedly connected with limit plates 14, and the movable plate 13 and the limit plates 14 are fixedly connected by bolts. The arrangement of the limit plates 14 plays a limiting role in the horizontal movement of the movable plate 13, which can avoid the disengagement of the movable plate 13 from the sliding groove 100.

[0033] In the embodiment, the cross-sectional shape of the notch 102 is rectangular, and the gear 15 penetrates the notch 102. The rectangular notch 102 is conducive to the penetration of the gear 15, thereby avoiding the influence of the notch 102 on the smooth rotation of the gear 15.

[0034] In the embodiment, the mold cavities 110 and the male molds 22 are arranged in a matrix, and the mold cavities 110 and the corresponding male molds 22 are located on the same vertical axis. This design facilitates the insertion of the male molds 22 into the mold cavities 110 to cooperate with the mold cavities 110 for injection molding.

[0035] In the embodiment, the guide rods 17 are fixedly connected to the top of the base 10 by bolts, and the guide rods 17 are slidably connected to the top seat 20. The guide rods 17 increase the stability and smoothness of the lifting movement of the top seat 20, and ensure the use stability of the top seat 20.

[0036] It should be noted that the bottom of the cavity 110 is in close contact with the top of the movable plate 13, and when the injection molding operation is performed, the molten material falls into the cavity 110 on the top of the movable plate 13, so the movable plate 13 does not affect the molding of the product. In addition, when part of the waste adheres to the cavity 110, the user can use a brush to clean it so that the waste falls into the collecting groove 130.

[0037] It should be noted that the motor 16 involved in the embodiment is a conventional technology, and will not be described here.

[0038] In specific use, the user first connects the power supply of the motor 16, and the motor 16 starts to work. The output shaft of the motor 16 rotates to drive the gear 15 to rotate. Since the gear 15 is engaged with the tooth groove 131, the rotation of the gear 15 drives the horizontal movement of the movable plate 13. At this time, the guide groove 132 slides along the guide rail 101. When the collecting groove 130 moves below the plurality of cavities 110, and the right end of the limiting plate 14 abuts against the base 10, the user stops the power supply of the motor 16. At this time, under the action of gravity, the waste in the cavity 110 falls into the cavity 110.

[0039] The basic principle, main features and advantages of the present application are shown and described above. It should be understood by those skilled in the art that the present application is not limited by the above embodiments, and the above embodiments and descriptions in the specification are only preferred examples of the present application and do not limit the present application. Without departing from the spirit and scope of the present application, the present application can also have various changes and improvements, and these changes and improvements all fall within the scope of the claimed present application. The scope of protection of the present application is defined by the appended claims and their equivalents.
