[0011] In order to enable those skilled in the art to better understand the technical solution of the utility model, the preferred implementation scheme of the utility model is described below in conjunction with specific embodiments, but it should be understood that these descriptions are only for further illustrating the features and advantages of the utility model, rather than limiting the patent requirements of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the utility model.

[0012] The utility model is further described below in conjunction with the accompanying drawings and preferred embodiments.

[0013] Example 1

[0014] See also Figures 1 to 5 As shown, the present embodiment involves a plastic wheel frame mold of a slider-insert combination, comprising a lower mold 1 and an upper mold 2 arranged above the lower mold, a molding cavity is provided between the lower mold 1 and the upper mold 2, a part of which is opened on the upper mold and the other end of which is opened on the lower mold, an upper insert 3 connected to the upper mold 2 and a lower insert 4 connected to the lower mold 1 are provided in the molding cavity, a semi-cylindrical protrusion 5 with a molding shaft hole is provided on the lower insert 4, and the axis of the semi-cylindrical protrusion 5 is horizontally extended left and right, and side sliders 6 for horizontal left and right movement are respectively provided on the left and right sides of the lower insert 4, and the side sliders 6 are slidably connected to the lower mold 1, and a side molding block 7 is provided on the end of any side slider 6 facing the other side slider 6, and an axis hole molding column 8 is provided on the side molding block 7 and is coaxially arranged with the semi-cylindrical protrusion 5, and the axis hole molding column 8 is against one side of the semi-cylindrical protrusion 5.

[0015] In this embodiment, after the mold is installed on the injection molding machine, the side slider 6 needs to be connected to an external power source, which can be the tension provided by a spring, a cylinder or an oil cylinder, so that the side slider 6 can be moved outward in the mold opening state.

[0016] When the upper mold 2 moves upward, the product is exposed, and the side slider 6 moves outward until the side forming block 7 is separated from the product, and the shaft hole forming column 8 inserted into the product is pulled out axially to form shaft holes at both ends, and the structure formed by the semi-cylindrical protrusion 5 is connected to the outside world, and the shaft holes formed at both ends are combined to form the entire shaft hole structure. Such a mold can also make the top surface of the demoulded plastic wheel frame body 100 into a smooth surface without burrs formed by parting.
