Description

Technical Field

[0001] The invention relates to the field of safety shoe processing equipment, in particular to a safety shoe forming mold. Background Art

[0002] At present, the toe cap of a safety shoe made of plastic is usually made by placing a heated and softened sheet on a molding module, and then manually bending and deforming the sheet along the shape of the molding module to obtain a molded rough blank of the safety shoe toe cap. The manual processing method has low processing efficiency, and there are errors in the specifications of the molded safety shoe toe cap, resulting in a high rate of product failure. Summary of the invention

[0003] The technical problem to be solved by the present invention is to address the deficiencies of the above-mentioned prior art. Provided is a safety shoe toe molding die, which is used to mold the safety shoe toe, and has high molding efficiency and qualified rate.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a safety shoe toe molding mold, comprising an upper mold and a lower mold base, characterized in that: the lower mold base is provided with a lower mold, the upper mold is detachably provided with at least one molding die head, the lower mold is provided with an adaptive molding cavity corresponding to the molding die head, the lower mold is connected to the molding cavity and a placement cavity is provided on the end face of the lower mold facing the upper mold, a sheet positioning plate is provided in the placement cavity, the sheet positioning plate is provided with a sheet placement groove corresponding to the molding cavity, and a demolding device is provided at the bottom of the molding cavity.

[0005] The present invention with the above characteristics: the sheet is placed in the sheet placement groove, and the sheet is extruded and formed in the forming cavity by the pressing forming die head of the upper mold and the lower mold. According to the number of the forming die heads, multiple safety shoe toe rough blanks can be formed at one time.

[0006] A further configuration of the present invention is that the molding die includes a die base and a die provided on the die base, a top arc surface is provided on one side of the top of the die that matches with the inner arc surface of the upper end of the safety shoe toe, and a stopper is provided on the side of the die opposite to the top arc surface that matches with the arc-shaped opening at the bottom of the safety shoe toe, and the upper die is provided with an installation groove that is tightly plugged into and adapted to the die base.

[0007] The present invention having the above characteristics: each part of the die head is corresponding to the toe of the safety shoe.

[0008] A further configuration of the present invention is that the demoulding device comprises a movable block, the movable block is provided with a spring, the spring is fixedly connected to the lower die base, the lower die corresponds to the molding cavity and is provided with a movable groove connected to the molding cavity, and the movable block is movably arranged in the movable groove.

[0009] The present invention with the above characteristics: during molding, the spring is compressed, the movable block abuts against the lower die seat to form a supporting force, which is convenient for molding and extrusion. After molding is completed, the spring is reset, and the interactive block moves in the movable groove to push the molded safety shoe toe out of the molding cavity.

[0010] A further configuration of the present invention is that the sheet placement groove includes a straight side and an arc-shaped side, and the straight side and the stopper are on the same side.

[0011] The present invention having the above characteristics can facilitate the positioning of the sheet material.

[0012] A further configuration of the present invention is that: the die head is provided with air holes, and the installation groove is connected to an air outlet groove.

[0013] A further configuration of the present invention is that the sheet positioning plate is tightly arranged in the placement cavity by fixing screws.

[0014] The present invention with the above characteristics ensures that there is no gap between the sheet positioning plate and the placement cavity, thereby preventing the sheet from overflowing from the gap when being squeezed.

[0015] A further configuration of the present invention is that the bottom edge of the molding cavity and the opening of the molding cavity are both chamfered.

[0016] The present invention has the above-mentioned characteristics: the chamfer arrangement makes the sheet material more gentle during extrusion, thus avoiding damage to the sheet material due to right angles.

[0017] A further configuration of the present invention is that: the movable block is provided with an ejector pin corresponding to the air hole.

[0018] The present invention has the above-mentioned features: the ejector cooperates with the air hole to drill a through hole on the toe of the safety shoe, so as to prevent the toe of the safety shoe from being attached to the die head due to air pressure, and facilitate demoulding.

[0019] The beneficial effects of the present invention are: the toe cap of the safety shoe is formed by the mold, and the forming efficiency and the qualified rate are high.

[0020] The present invention is further described in detail below with reference to the accompanying drawings and embodiments. BRIEF DESCRIPTION OF THE DRAWINGS
