[0031] like Figure 1 , Figure 3 , Figure 5 , Figure 7 As shown, an embodiment of the present application provides an injection mold for a vehicle reading light panel, comprising a first fixed plate 1, a fixed mold 2, a movable mold 3, an ejection mechanism 4 and a second fixed plate 5 which are arranged in sequence, the fixed mold 2 is provided with a fixed mold core, the fixed mold core is provided with a profiling groove at one end close to the movable mold 3, the movable mold 3 is provided with a movable mold core 31, the movable mold core 31 is provided with a profiling protrusion 311, and profiling components 100 are respectively provided on the fixed mold core and the movable mold core 31, the profiling component 100 extends into the profiling groove and the profiling protrusion 311 and forms a molding cavity with the profiling groove and the profiling protrusion 311.
[0032] like Figure 2 , Figure 8 As shown, the fixed mold 2 and the fixed mold core are provided with a casting mechanism 6 connected with the molding cavity, and the ejection mechanism 4 is used to eject the panel 10 in the molding cavity out of the mold.
[0033] like Figure 3 As shown, a plurality of clamping components 7 for fixing the movable mold core 31 and the fixed mold core are fixedly arranged on the fixed mold 2 and the movable mold 3.
[0034] The profiling assembly 100 includes a plurality of No. 1 profiling blocks 101 adapted to the forming cavity and a plurality of No. 2 profiling blocks 102 adapted to the forming cavity.

Five clamping components 7 are respectively provided on the outer sides of the movable mold core 31 and the fixed mold core, and the clamping components 7 are respectively fixedly mounted between the movable mold 3 and the fixed mold 2 and abut against one side of the movable mold core 31 and the fixed mold core to fix the movable mold core 31 and the fixed mold core.
[0036] During the injection molding process, the driving mechanism drives the fixed mold 2 and the movable mold 3 to close, so that multiple No. 1 profiling blocks 101 and multiple No. 2 profiling blocks 102 are pressed onto the molding cavity to form a complete casting system and molding cavity, and the heated and melted plastic material flows from the casting mechanism 6 into the molding cavity. After cooling and solidification, the driving mechanism drives the fixed mold 2 and the movable mold 3 to separate, and the ejection mechanism 4 is driven to eject the injection molded panel 10 from the injection mold for demolding, and finally the unloading mechanism removes the panel 10.

When the fixed mold 2 and the movable mold 3 are pressed together, the clamping block 002 of the second profiling block 102 drives the second profiling block 102 to move along the sliding groove 001 of the fixed block 103, so that the second profiling block 102 is firmly pressed on the molding cavity. This arrangement facilitates the second profiling block 102 to be firmly pressed on the molding cavity, which is conducive to improving the precision of the injection molding process of the injection mold.
