To the woman's shoe that has the shoelace, add man-hour, need place the fixed clamp in of shoelace bottom in shoes insole and shoes outsole. In addition, the plastic middle sole of the existing women's shoes is made of a single material, and the oxidation resistance and the mechanical property of the plastic middle sole are weaker and need to be improved.

Disclosure of Invention

Aiming at the defects in the prior art, the invention aims to provide the plastic insole for the women's shoes, which has the advantages of oxidation resistance and capability of adjusting the proportions of various mixtures in the insole according to actual conditions.

In order to achieve the purpose, the invention provides the following technical scheme: the processing method of the plastic insole of the women's shoes comprises a specially-made mold, wherein the specially-made mold comprises a first bottom mold, a first injection hole is formed in the upper section of the first bottom mold, a second bottom mold is clamped with the first bottom mold, the second bottom mold comprises hollow columns, a side wall of the first bottom mold is integrally connected with a placing block with an opening, a guide rod is integrally connected to the outer side of the second bottom mold, the guide rod extrudes the inside of the placing block, each hollow column is respectively communicated with a first injection pipe, a sliding groove for sliding the first injection pipe is formed in the inner side of the first bottom mold, the bottom of the sliding groove is extruded by the first injection pipe, when the first bottom mold is clamped with the second bottom mold, the first bottom mold is provided with second injection holes which are in one-to-one correspondence and communication with a plurality of first injection pipes, a clamping groove is formed in the upper end of the first bottom mold, and the first bottom mold is hinged to the opening, the second bottom die is rotationally connected with a bending plate, one end of the bending plate, which is far away from the second bottom die, is integrally connected with a semicircular block, the first bottom die is provided with a semicircular groove for clamping the semicircular block,

the processing method of the plastic insole of the women's shoes comprises the following steps:

the method comprises the following steps: prefabricating a special mold, clamping the second bottom mold into the first bottom mold, and injecting plastic into the first injection hole under the conditions of 180-;

step two: injecting one or more of rubber, EVA and TPR into the second injection hole at the temperature of 180-200 ℃;

step three: taking out the second bottom die under the conditions of 180-;

step four: taking another prefabricated special mold, stacking the special mold at the opening of the first bottom mold which is prepared in the third step to obtain a single-layer mixed structure, repeating the first step, the second step and the third step to obtain a double-layer mixed structure,

step five: step four can be repeated for a plurality of times according to the multilayer mixed structure to be obtained;

step six: dismantling the first bottom die and the second bottom die in the fifth step, and placing under the pressure of 0.4PMa for 60min until the volume is not changed any more;

step seven: and taking out the product obtained in the sixth step, and spraying the titanium alloy in multiple directions.

Through adopting above-mentioned technical scheme, when not inserting the metal sheet, articulated slab seals the card and enters the groove, plays isolated effect. The invention takes the plastic as a main body, has the advantages of environmental protection, difficult folding and lightness of the plastic sole, one or more of rubber, EVA and TPR is distributed in the inner part, other materials can be utilized to make up the defects of the plastic, and the size of the hollow column of the second plastic can be prefabricated according to the requirement and is suitable for different requirements, so the proportion relation between the plastic and other components can be changed, the aim of balance is achieved, and the mixed use has higher use value and higher mechanical performance. In-process toward downthehole notes liquid of first filling hole and second injection, let first die block and second die block rock each other easily, consequently rotatory bending plate drives the semicircle piece and rotates, and then lets the semicircle piece card go into the semicircular groove to realize the fixed connection between first die block and the second die block, guarantee the normal clear of follow-up procedure. When the semicircle block card goes into the semicircle orifice in, the bottom of first die block will be extruded to hollow post to let second die block and first die block constitute confined space, follow first filling hole and pour into the raw materials after, form rudiment, also can restrict the raw materials outflow second die block in the second die block simultaneously, form two relative confined spaces.
