Description

Mold for integrally molding injected sole and vamp

[ technical field ] A method for producing a semiconductor device

The utility model relates to a shoemaking field, especially a mould that jets out sole and vamp integrated into one piece.

[ background of the invention ]

The traditional sole manufacturing process generally needs to coat glue on a formed sole and then stick the sole on the inclined plane of the bottom of an upper, and the process is not environment-friendly and is easy to degum.

[ Utility model ] content

The to-be-solved technical problem of the utility model is to provide an environmental protection and can improve production efficiency's a mould that jets out sole and vamp integrated into one piece.

The purpose of the utility model is realized like this:

a mold for integrally molding an injected sole and a vamp comprises a mold base, wherein a mold cavity matched with the sole in shape is arranged at the top of the mold base, an upward convex ring is arranged on the peripheral edge of the mold cavity to abut against the bottom edge of a vamp edge strip, an injection hole for injecting a molten sole material is formed in one side of the mold base, injection holes communicated with the injection holes and used for injecting the molten sole material are formed in the bottom and/or the side of the mold cavity, and a channel for communicating the injection holes with the injection holes is formed in the mold base.

The above structure is adopted in the utility model, the upper of a shoe that will make up the vamp welt is placed on the die cavity, make the bottom edge and the bulge loop looks butt of vamp welt, thereby make to be formed with the shaping space between vamp welt and the die cavity, at this moment through penetrating the machine of glue and to penetrating into melting sole material downthehole, melting sole material jets out to forming die's die cavity through the passageway and jet out the hole on, it is full of to fill up in the shaping space that melting sole material will be formed between vamp welt and die cavity, can be with sole integrated into one piece in the bottom vamp of vamp welt and upper of a shoe after melting sole material cools off, the sole manufacturing process that the application this mould goes on is simple and convenient, need not the rubber coating, the environmental protection is durable, and production machining.

According to the mold for integrally molding the injection sole and the vamp, the limiting boss for limiting the circumferential outer side of the vamp welt is arranged on the circumferential outer side of the convex ring, so that the vamp welt is effectively positioned.

The mold for integrally molding the shoe sole and the shoe upper further comprises two movable cover plates which are movably arranged on two sides of the top of the mold base, and inclined planes used for pressing the shoe upper edge strips on the convex rings are arranged on the inner sides of the two movable cover plates, so that the shoe upper edge strips are effectively prevented from shifting in the processing process.

fig. 5 is a schematic view of the structure of the finished product after the sole is formed by using the utility model.

[ detailed description ] embodiments

A mold for integrally molding an injected sole and a vamp comprises a mold base 1, wherein a mold cavity 2 matched with the sole in shape is arranged at the top of the mold base 1, an upward convex ring 3 is arranged on the mold cavity 2 along the circumferential edge of the mold cavity for abutting against the bottom edge of the vamp edge strip 200, an injection hole 4 for injecting a molten sole material is arranged at one side of the mold base 1, an injection hole 5 communicated with the injection hole 4 and used for injecting the molten sole material is arranged at the bottom and/or the side of the mold cavity 2, and a channel 45 for communicating the injection hole 4 with the injection hole 5 is arranged in the mold base 1.

For effectively fixing the position of the vamp welt 200, the circumferential outer side of the convex ring 3 is provided with a limiting boss 6 for limiting the circumferential outer side of the vamp welt 200.

In order to effectively prevent the displacement of the upper welt 200 in the processing process, the mold for injecting the shoe sole and the shoe upper into a whole further comprises two movable cover plates 7 which are movably covered on two sides of the top of the mold base 1, and the inner sides of the two movable cover plates 7 are provided with inclined planes 71 which are used for pressing the upper welt on the convex rings 3.

In the application of the utility model, the process for forming the sole comprises the following steps in sequence:

a: stitching, sewing vamp welt 200 to the bottom edge of upper 100;

b: positioning, namely placing the upper 100 sewn with the upper welt 200 on the cavity 2 of the forming mold through a last, and enabling the bottom and the side part of the upper welt 200 to be respectively abutted against the convex ring 3 and the boss 6 of the forming mold, so that a forming space is formed between the upper welt 200 and the cavity 2;

c: clamping, namely covering two cover plates 7 of the forming die on the top of the die holder 1, and enabling inclined planes 71 on the inner sides of the two cover plates 7 to tightly press the vamp welts 200 on the convex rings 3;

d: injecting a melted sole material into an injection hole 4 of a forming mold through an injection molding machine, and injecting the melted sole material onto a cavity 2 of the forming mold through a channel 45 and an injection hole 5 until the melted sole material fills a forming space formed between the upper edge strip 200 and the cavity 2 (the melted sole material can be a foamed rubber synthetic material, TPU, PVC, TR, PR or TPR, etc.);

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

f: and (4) demolding, namely taking the cover plate 7 out of two sides of the top of the die holder 1, and then taking the shoe with the formed sole out of the forming die through a last.

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