Description

Microwave-permeable mold structure and its use method

The present invention relates to a mold that cooperates with microwave energy and is used for components of footwear articles, and particularly relates to a mold structure that is transparent to microwaves.

The present invention also relates to a method of using the aforementioned microwave-permeable mold structure.

General shoe components, such as midsoles or outsoles, can be glued together with adhesives. The traditional method is to increase the temperature of the components by ovens, etc., so that the adhesive can obtain sufficient temperature. However, the use of traditional heat sources has Inefficiency and other defects;

Therefore, microwave heating has emerged in the industry. However, the shoe components to be processed are all made of foamed materials, such as EVA (polyethylene vinyl acetate). The aforementioned materials will expand after being heated by microwaves, causing the inside of the mold to expand. Therefore, if the microwave directly penetrates the mold to heat the shoe components, the pressure inside the mold will be large enough to open the mold, causing many subsequent problems;

Therefore, the industry has developed a shoe manufacturing mold suitable for microwave energy. As shown in Figures 1 and 2, the aforementioned mold 90 is made of a material that is impenetrable to microwaves, and a cavity is formed in the center of the mold 90 91. The shoe component to be processed is placed in the cavity 91, and the outer surface of the mold 90 has a window 92 that allows microwaves to penetrate, and the window 92 is connected to the cavity 91, so that the microwave energy can only enter through the window 92 Inside the cavity 91 and reflected inside the cavity 91 to achieve the heating effect;

However, the conventional shoe-making mold only allows microwave energy to enter the cavity 91 through the window 92, so that the shoe components cannot receive the microwave energy uniformly, resulting in poor processing effects and uneven heating. For this reason, a kind of Microwave-permeable mold structure.

The present invention provides a microwave-permeable mold structure, the main purpose of which is to enable shoe components to be heated evenly during the heating process and to improve the yield of the finished product.
