[0020] The die-casting die of the lock shell can simultaneously obtain two products during die-casting, and the production efficiency of the products is ensured.

[0021] The die-casting die of the lock shell further comprises an inclined guide rod 10 and a moving block 20, the inclined guide rod 10 is obliquely arranged, one end of the inclined guide rod 10 is fixed on the upper die plate 1, the other end can penetrate through the moving block 20, and the moving block 20 is fixed on the outer side of the slide block 8.

[0022] The die-casting die of the lock shell further comprises a limiting block 30, the limiting block 30 is fixed below the upper die plate 1, the inner side of the limiting block 30 is provided with a first inclined surface, the outer side of the moving block 20 is provided with a second inclined surface, the limiting block 30 is located on the outer side of the inclined guide rod 10, and the first inclined surface can be matched with the second inclined surface.

[0023] Specifically, when the mold is closed, the upper die plate 1 drives the inclined guide rod 10 to move downward, the inclined guide rod 10 is inserted into the moving block 20, so that the moving block 20 is moved to one side of the cavity under the pushing action of the inclined guide rod 10; when the moving block 20 moves, the sliding block 8 is driven to move to one side of the cavity, and the mold closing of the sliding block 8 is realized. When the upper die plate 1 moves downward, the limiting block 30 moves downward, the first inclined surface of the limiting block 30 is tightly attached to the second inclined surface of the moving block 20, so that when the sliding block 8 is closed in place, the moving block 20 can be further pressed by the limiting block 30, so as to avoid the movement of the sliding block 8 during die casting. Conversely, when the product is finished, the upper die plate 1 moves upward, the inclined guide rod 10 moves upward, the limiting effect of the limiting block 30 on the moving block 20 is removed, the moving block 20 moves outward under the action of the inclined guide rod 10, the mold opening of the sliding block 8 is realized, and the sliding block 8 is separated from the product and the ladle.
