[0023] See also Figure 1-3The utility model provides a technical solution: an easy-to-form cover injection mold, including a mold frame, on which a movable mold 3 and a fixed mold 4 are installed, a molding cavity is formed between the fixed mold 4 and the movable mold 3, and is used to injection mold a workpiece body 12; sliders 2 are slidably connected on both sides of the fixed mold 4; a driving member for driving the slider 2 to slide is provided on the mold frame; the driving member includes an inclined guide column 5 slidably connected to the mold frame, and a guide groove 6 adapted to the inclined guide column 5 is opened on the slider 2, and the inclined guide column 5 is slidably connected to the guide groove 6.

[0024] Specifically, the easy-to-form cover body injection mold includes a mold frame, a movable mold 3 and a fixed mold 4 are installed on the mold frame, and a molding cavity is formed between the fixed mold 4 and the movable mold 3, which is used to injection-mold the workpiece body 12. The injection molding method of the fixed mold 4 and the fixed mold 4 is a prior art and will not be described here. Sliders 2 are slidably connected on both sides of the fixed mold 4. Specifically, the number of slides 2 on both sides is set according to the needs of the working environment. A driving member for driving the slide 2 to slide is provided on the mold frame, thereby facilitating the sliding of the slide 2. Specifically, the driving member includes an inclined guide column 5 slidably connected to the mold frame, and a guide groove 6 adapted to the inclined guide column 5 is provided on the slide 2. The inclined guide column 5 is slidably connected to the guide groove 6. At this moment, when the inclined guide column 5 slides inside the guide groove 6, it can drive the slide 2 to slide on the fixed mold 4. Therefore, when using the injection mold, the fixed mold 4 and the movable mold 3 are driven to approach each other, and the slider 2 is driven by the inclined guide column 5 to drive the mold 3 core to adapt to the molding cavity for injection molding the workpiece body 12, thereby improving the working efficiency of the injection mold. After the injection mold completes the injection molding of the workpiece body 12, the inclined guide column 5 slides vertically on the mold frame, which will drive multiple groups of sliders 2 to slide away from the workpiece body 12 to meet the working needs. At the same time, by changing the slider 2 from a whole to multiple groups, the size of the slider 2 and the mold core on the slider 2 can be designed more flexibly.
