Description

Microwave-permeable mold structure

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

General shoe components, such as midsoles or outsoles, can be glued together using an adhesive. The traditional method is to increase the temperature of the component by using an oven or the like to achieve a sufficient temperature for the adhesive. However, the traditional heat source method has Lack of efficiency, etc.

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

For this reason, the industry has developed a shoe manufacturing mold suitable for microwave energy. As shown in Figures 1 and 2, the mold 90 is made of a material that cannot be penetrated by microwaves, and a cavity is formed at the center of the mold 90 91, the shoe parts to be processed are placed in the cavity 91, and the outer surface of the mold 90 has a window 92 through which microwaves can pass, and the window 92 communicates with the cavity 91, so that microwave energy can only enter through the window 92 Inside the cavity 91 and reflecting in the cavity 91 to achieve the effect of heating;

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, which causes the processing effect to be poor and the heating unevenness is missing. Therefore, 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 parts to be uniformly heated during the heating process and improve the yield of the finished product.
