[0020] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings of the embodiments of the present application. Obviously, the described embodiments are some of the embodiments of the present application but not all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0021] The technical solutions of the embodiments of the present application will be described in detail below in conjunction with the drawings.

[0022] The utility model discloses a mould structure of preventing bruising and pulling injury, like Figures 1-3As shown in the drawings, the upper die 1 is provided with at least four mounting holes 3, and the upper die 2 is provided with holes corresponding to the at least four mounting holes 3 on the side close to the upper die 1. The mounting holes 3 are provided with fixing structures for limiting the vertical position of the upper die 2 relative to the upper die 1.

[0023] It should be noted that the fixing structure is fixed with the upper die and does not exist in the connection relationship with the upper die, and the fixing structure is abutted on the bottom wall of the mounting hole 3 through the protective sleeve 5 or other extended structure, so that the upper die 2 and the upper die 1 are tightly attached, and the position relationship in the vertical direction is limited, and at the same time, the protective sleeve 5 or other extended structure is a wear-resistant structure to improve the service life of the die.
