Description

A mold for integral molding of shoe sole and shoe upper

【Technical field】

The utility model relates to the field of shoemaking, in particular to a mold for integrally molding a shoe sole and a shoe upper.

【Background technique】

The traditional shoe sole manufacturing process generally requires applying glue on the formed shoe sole, and then sticking the shoe sole on the inclined surface of the bottom of the shoe upper, which is not environmentally friendly and easy to degumming.

【Content of utility model】

The technical problem to be solved by the utility model is to provide a mold that is environmentally friendly and can improve production efficiency by injecting the sole and the shoe upper into one piece.

The purpose of this utility model is achieved in this way:

A mold for injecting soles and shoe uppers into one piece, including a mold base, the top of the mold base is provided with a cavity that matches the shape of the sole, and the cavity is provided with an upwardly protruding edge along its circumferential edge. The convex ring is used for abutting the bottom edge of the upper along the strip, one side of the mold base is provided with an injection hole for the molten sole material to be injected into, and the bottom and/or side of the cavity is provided with the The injection holes communicate with each other and are used for injection of molten shoe sole material, and the mold base is provided with a channel connecting the injection holes and the injection holes.

The utility model adopts the above-mentioned structure, and the shoe upper with the welt of the upper sewn is placed on the cavity, so that the bottom edge of the welt of the upper is abutted with the convex ring, so that there is formed between the welt of the upper and the cavity. In the molding space, the molten sole material is injected into the injection hole by the glue injection machine, and the molten sole material is injected into the cavity of the molding die through the channel and the injection hole, until the molten sole material will be formed on the upper welt and the mold. The molding space between the cavities is filled. When the molten sole material cools, the sole can be integrally formed on the welt of the upper and the bottom upper of the upper. The sole manufacturing process using this mold is simple and convenient, no need to apply glue, and is environmentally friendly and durable. , but also to improve production and processing efficiency.

The above-mentioned mold for integral molding of the sole and the upper, the circumferential outer side of the convex ring is provided with a limiting boss for limiting the circumferential outer side of the upper along the strip, so as to effectively prevent the upper Position along the bar.

The above-mentioned mold for integral molding of the sole and the upper of the shoe also includes two movable cover plates arranged on both sides of the top of the mold base. The strip is pressed against the inclined surface on the convex ring, thereby effectively preventing the upper welt from shifting during the processing.

【Detailed ways】

A mold for injecting soles and shoe uppers into one piece, including a mold base 1, the top of the mold base 1 is provided with a cavity 2 that matches the shape of the sole, and the cavity 2 is provided with upwardly convex along its circumferential edge. The convex ring 3 is used for abutting the bottom edge of the upper welt 200, one side of the mold base 1 is provided with an injection hole 4 for injecting molten sole material, and the bottom and/or side of the cavity 2 is provided with The injection holes 4 communicate with each other and are used for injection holes 5 for the molten shoe sole material to be injected. The mold base 1 is provided with a channel 45 which communicates the injection holes 4 with the injection holes 5 .

In order to effectively position the welt 200 of the shoe upper, the outer circumferential side of the convex ring 3 is provided with a limiting boss 6 for limiting the outer side of the upper welt 200 in the circumferential direction.

In order to effectively prevent the upper welt 200 from being displaced during the processing, the above-mentioned mold for integrally molding the sole and the upper also includes two movable covers 7 arranged on both sides of the top of the mold base 1. The inner side of the movable cover plate 7 is provided with an inclined surface 71 for pressing the welt of the shoe upper against the convex ring 3 .

In the process of applying the present utility model to carry out sole molding, the following steps are included in sequence:

A: Car thread, sew the upper welt 200 on the bottom edge of the upper 100;

B: Positioning, the shoe upper 100 sewn with the upper welt 200 is placed on the cavity 2 of the forming mold through the last, and the bottom and side parts of the shoe upper welt 200 are respectively connected with the convex ring 3 of the forming die Abutting with the boss 6, so that a molding space is formed between the upper welt 200 and the cavity 2;

C: clamping, the two cover plates 7 of the molding die are covered on the top of the die base 1, and the inclined surfaces 71 on the inner sides of the two cover plates 7 press the upper welt 200 on the convex ring 3;

D: inject the sole, inject the molten sole material into the injection hole 4 of the molding die through the glue injection machine, and inject the molten sole material to the cavity 2 of the molding die through the channel 45 and the injection hole 5, until the molten sole material will form Fill the molding space between the upper welt 200 and the cavity 2 (the molten sole material can be foamed rubber synthetic material, TPU, PVC, TR, PR or TPR, etc.);

E: cooling and forming, standing to cool the molten sole material, and integrally forming the upper welt 200 and the bottom upper of the upper 100 (cooling time is 2 minutes to 30 minutes);

F: Demoulding, take out the cover plate 7 from the top and both sides of the mold base 1, and then take out the shoe with the sole formed from the forming mold through the last.

In order to improve the compressive strength of the sole, in the sewing step, the upper welt 200 is sewn on the shoe upper 100 and the TPU frame 300 is sewn on the inner side of the upper welt 200 .
