[0005] A further configuration of the present invention is: the safety shoe toe positioning block includes a positioning head and a molding seat, the molding seat is arranged corresponding to the rubber strip molding gap, the safety shoe toe sleeve is arranged on the positioning head, and the rubber strip portion of the safety shoe toe is arranged corresponding 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 sleeve is arranged on the positioning head, a molding gap of the rubber strip adhesion portion is formed between the safety shoe toe and the bottom of the positioning head, and the molding gap of the rubber strip adhesion portion is connected with the rubber strip molding gap.

[0006] A further configuration of the present invention is that a stopper for forming a gap in the rubber strip is provided on the side of the forming seat.

[0007] A further configuration of the present invention is that the injection hole penetrates through the lower die to the top of the positioning head.

[0008] The present invention with the above characteristics: the material is injected from the injection hole, the material flows along the surface of the safety shoe toe positioning block to the rubber strip molding gap and the rubber strip adhesion portion molding gap, a part of the material is molded in the rubber strip adhesion portion molding gap and adheres to the safety shoe toe, and the other part of the material is molded into a rubber strip in the rubber strip molding gap, and the blocking block forms a rubber strip molding gap.

[0009] The beneficial effects of the present invention are as follows: the rubber strip is directly formed on the toe of the safety shoe, thus avoiding the adhesion caused by manual gluing, improving the connection accuracy and strength of the rubber strip, improving the reliability of the connection of the rubber strip, and improving the processing efficiency.

[0010] The present invention is further described in detail below with reference to the accompanying drawings and embodiments. BRIEF DESCRIPTION OF THE DRAWINGS
