Description

Shoe mold structure and its application method

The present invention relates to a mold, and more particularly to a mold for a shoe component.

The present invention also relates to a method of using the above-mentioned shoe mold structure.

General shoe components, such as midsoles or outsoles, can be bonded together with adhesives. The traditional method is to increase the temperature of the components by using ovens, etc., so that the adhesives can obtain sufficient temperature. However, using traditional heat sources The method has defects such as low efficiency;

For this reason, microwave heating has appeared in the industry, and the shoe parts to be processed are all made of foaming materials, such as EVA (ethylene-vinyl acetate copolymer), etc. The conventional microwave heating method is to make the microwave penetrate the mold directly Heating the shoe parts. Although the direct heating of the shoe parts by the microwave penetrating the mold is helpful for the combination of the shoe components, it is still prone to the problem of uneven heating. In addition, the microwave will make the upper or the shoe larger. The sole produces qualitative change and deterioration to affect the quality of the shoe body. For this reason, a shoe mold structure and its use method that can overcome the above-mentioned problems are needed.

The invention provides a shoe mold structure, the main purpose of which is to effectively combine the shoe outsole and the upper body, and avoid qualitative change and deterioration of the shoe outsole and the upper body.

The present invention also provides a method for using the above shoe mold structure.

In order to achieve the aforementioned object, the shoe mold structure of the present invention includes:

A mold body has an opposite first end and a second end, the extension direction between the first end and the second end is a longitudinal direction, and the mold body has a mold cavity in addition, and the mold cavity is formed from the The second end is concave, and the mold system is composed of a bottom wall and a plurality of side walls, each side wall defines a first side section, a second side section and a third side section connected in sequence along the longitudinal direction, The second side section is located between the first side section and the third side section, the first side section is closer to the first end than the third side section, and the third side section is closer to the first side section than the first side section the second end, the second side section has a receiving groove; and

A heating unit is arranged in the accommodating tank, and the heating unit is used for providing heat energy.

The present invention also provides a method for using the above-mentioned shoe mold structure, including:

A step of inserting the upper body, providing the mold body and an upper body, placing the upper body upside down into the mold cavity, the upper body having a sole;

A step of inserting foams, placing multiple foams into the mold cavity and placing them on the bottom of the shoe;

A step of inserting a shoe outsole, placing a shoe outsole into the mold cavity, and placing the shoe outsole on the foams, and the foams are located between the shoe upper and the shoe outsole ;

A mold closing step, closing the mold cavity of the mold body; and

In a heating step, the foam body is heated independently through the heating unit to form a shoe midsole, and the shoe upper body and the shoe outsole are connected through the shoe midsole.

It can be seen from the above that the shoe mold structure of the present invention mainly defines the side wall as the first side section, the second side section and the third side section, so that the position of the second side section corresponds to the foam body, and on the second side The accommodating groove is opened in the section, and the heating unit is arranged in the accommodating groove, so that the heating unit can heat the foam body independently, so as to avoid qualitative change and deterioration of the shoe outsole and the vamp body.

The present invention relates to a shoe mold structure, please refer to Fig. 1, including:
