[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-6 .

[0031] To address the inconvenience of disassembling and replacing inserts in existing molds, particularly when inserts fail or are damaged, this solution provides a wear-resistant insert for a die-casting mold of new energy vehicle parts. The insert comprises an automotive parts mold 1 and an insert body 3. A movable rod 5 is telescopically connected to the lower end of the automotive parts mold 1, with its rear end inserted into a fixing block 4 fixed to the lower end of the insert body 3. An ejection mechanism 11 is symmetrically arranged at the left and right ends of the automotive parts mold 1, pushing the insert body 3 upwards to remove it from the automotive parts mold 1.

[0032] As shown in the figure, the insert body 3 is fitted into the mounting cavity 2 inside the automotive parts mold 1, and the insert body 3 is made of hard alloy wear-resistant material, which has good wear resistance. Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the hand-held fixing ring 7 pushes the movable plate 6 backward, the movable plate 6 moves in the side plate 8, and the movable plate 6 drives the fixed rod 9 to slide between the side plate 8. At the same time, the movable plate 6 pushes the movable rod 5 to slide in front of the automotive parts mold 1, so that the rear end of the movable rod 5 is inserted into the fixing block 4 fixed at the lower end of the insert body 3, which facilitates the installation and positioning between the insert body 3 and the automotive parts mold 1, and improves the stability of the insert body 3 during use. Then, the fixing cap 10 threaded to the outer surface of the fixing rod 9 is rotated, so that the fixing cap 10 fits tightly against the outer side of the side plate 8, which facilitates the limiting between the fixing rod 9 and the side plate 8, and realizes the fixation between the movable rod 5 and the automotive parts mold 1.

[0033] Furthermore, when it is necessary to disassemble and replace the insert body 3, such as Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, the ejection mechanism 11 consists of an ejection plate 12 placed inside the automotive parts mold 1, a connecting block 13 fitted to the inner side of the ejection plate 12, a crossbar 14 fixedly connected to the outer side of the connecting block 13, a spring 15 sleeved on the outer side of the crossbar 14, and an auxiliary block 16 fixedly connected to the outer side of the crossbar 14. First, the movable rod 5 is moved out of the fixed block 4, releasing the limiting position between the fixed block 4 and the automotive parts mold 1. Then, the auxiliary block 16 is pressed directly towards the side closest to the vertical central axis of the automotive parts mold 1. The auxiliary block 16 pushes the crossbar 14 to slide in the automotive parts mold 1. The springs 15 are compressed, causing them to deform elastically. The crossbar 14 drives the connecting block 13 to move within the automotive parts mold 1. The ejector plate 12 is fitted to the lower end of the insert body 3, and the inner side of the upper end of the ejector plate 12 matches the upper end of the connecting block 13. The crossbar 14, together with the connecting block 13, pushes the ejector plate 12 upward, causing the ejector plate 12 to push the insert body 3 upward from the mounting cavity 2. This facilitates the disassembly and replacement of the insert body 3. In particular, when the insert body 3 malfunctions or fails, it can also be ejected, making the overall disassembly operation relatively convenient.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
