This manual gluing method is costly, inefficient, and lacks precision. Furthermore, the glue connection method is not robust enough, resulting in unreliable adhesion of the rubber strip. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to address the shortcomings of the existing technology.

[0004] A mold for forming a rubber strip and the toe of a safety shoe is provided. The rubber strip is directly formed onto the toe of the safety shoe, avoiding manual glue application and adhesion, improving the accuracy and strength of the rubber strip connection, improving the reliability of the rubber strip connection, and improving processing efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mold for forming a rubber strip on the toe of a safety shoe, characterized in that: it includes an upper mold, a rubber strip forming mold, and a lower mold; the lower mold has at least one safety shoe toe positioning block on one end face facing the upper mold; the safety shoe toe positioning block can fit onto the toe of a safety shoe; the rubber strip forming mold is provided corresponding to the rubber strip adhesion part of the safety shoe toe; the rubber strip forming mold has a rubber strip forming cavity corresponding to the safety shoe toe positioning block; a rubber strip forming gap is provided between the rubber strip forming cavity and the safety shoe toe positioning block; the upper mold has a receiving cavity corresponding to the safety shoe toe positioning block that can accommodate the toe of the safety shoe; the lower mold has a through injection hole; the material injected through the injection hole flows to the rubber strip forming gap.

[0006] A further feature of this invention is that the safety shoe toe positioning block includes a positioning head and a molding seat. The molding seat is positioned to correspond to the forming gap of the rubber strip. The safety shoe toe is fitted onto the positioning head, and the rubber strip portion of the safety shoe toe is positioned to correspond to the molding seat. The bottom diameter of the molding seat is larger than the bottom diameter of the positioning head. When the safety shoe toe is fitted onto the positioning head, a forming gap for the rubber strip bonding portion is formed between the safety shoe toe and the bottom of the positioning head. The forming gap for the rubber strip bonding portion is connected to the forming gap of the rubber strip.

[0007] A further feature of this invention is that the side of the molding seat is provided with a stop block for forming a notch in the adhesive strip.

[0008] A further feature of this invention is that the injection hole extends through the lower mold to the top of the positioning head.

[0009] The utility model discloses the following beneficial effects: the glue strip is directly formed on the toe of the safety shoes, avoiding manual gluing and adhesion, improving the connection precision and strength of the glue strip, improving the reliability of the glue strip connection, and improving the processing efficiency.

[0010] The utility model discloses the following beneficial effects: the glue strip is directly formed on the toe of the safety shoes, avoiding manual gluing and adhesion, improving the connection precision and strength of the glue strip, improving the reliability of the glue strip connection, and improving the processing efficiency.

[0011] The utility model discloses the following beneficial effects: the glue strip is directly formed on the toe of the safety shoes, avoiding manual gluing and adhesion, improving the connection precision and strength of the glue strip, improving the reliability of the glue strip connection, and improving the processing efficiency.
