Description

 The production process of injection molding mold for injection molded breathing shoes, midsole for even injection molded breathing shoes and continuous injection molded breathing shoes Technical field

 The invention relates to an injection mold for a pair of injection-molded breathing ventilation shoes, and an injection molding breathing The midsole of the ventilation shoes and the production process of the injection-molded breathing shoes.

Background technique

Traditional shoes such as leather shoes, sports shoes, and later polyurethane-assisted injection molded shoes generally include an upper, an insole, a midsole or an outsole, and the midsole may be an outsole or an outsole and a middle. The combination of the bottom, the upper and the midsole are connected to form a body. The midsole of the polyurethane-integrated injection shoe is stitched to the upper and placed on a special mold to make the polyurethane (PU) The foamed material is foamed into the mold to form a shoe body. However, due to the compact structure of the shoes on the market, the inner cavity of the shoe tends to form a relatively closed space when worn, and the air in the inner cavity of the shoe can hardly be exchanged with the outside air, especially the part in which the foot and the shoe are closely adhered, such as The gas flow in the soles and other parts is even worse, so that the sweat and heat from the feet can not be removed from the shoes in time, forming a damp, stuffy inner environment, which not only makes people feel very uncomfortable, but also is very suitable for certain microorganisms (such as fungi). The reproduction is easy to cause 'foot odor' and various foot diseases, which brings a lot of inconvenience to people's lives. Even the situation of helping injection shoes is particularly serious. The key to solving the above problems is to try to make the air in the shoes flow and exchange with the outside air. Therefore, people have subsequently developed a variety of new health shoes such as wicking shoes, breathing shoes, and ventilating shoes that have the function of exchanging the inner cavity of the shoe with the outside air. The basic structure of such shoes usually includes the upper, the insole and the midsole; the production process of such a pair of shoes is to bond or sew the upper and the outsole to form the body of the shoe; but now the breathable shoes Generally, the sole is made of a mold according to a pre-designed style. (ie midsole) At the same time, the airbag storage chamber, the exhaust passage and the conduit slot are formed, and the airbag and the conduit are respectively installed in the airbag storage cavity and the conduit groove, and then the upper is glued or stitched to form the shoe body. The manufacturing method of the polyurethane integrated injection molding health shoes is generally formed by injection molding to form the middle and the air guiding groove and the ventilation groove and the pressing hole for the airbag protruding at the heel, with special equipment or tools in front of the inner bottom. The sole of the foot punches out the venting through hole and then connects the midsole with the upper through the folder or the pull bag and fixes it on the die, and then sutures or bonds the airbag on the bottom surface of the midsole, and then carries The midsole of the airbag is connected to the upper by means of a clip or a bag and is fixed on the die. The duct on the air inlet of the airbag is embedded in the air guiding groove, and the air inlet check valve is arranged in the duct and connected by a duct. The air chamber and the air bag, the intake check valve is placed in the catheter, and is fixed in the forefoot of the midsole, and the sewn upper and the midsole are placed on the hoe of the injection mold together with the airbag or the air chamber. , will polyurethane ( PU The foaming liquid is injected into the mold, and the mold is closed. After the mold is cured, the mold is removed, the shoes are trimmed, the edges are trimmed, the appearance is processed, and a one-way air outlet valve is installed at the corresponding position of the shoe, the inner bottom is placed, and the shoe is sprayed. Decoration, code, and final packaging. According to the above introduction, the production of various specifications of the existing various types of breathing shoes needs to be planned first, and the corresponding molds are prepared, and the market situation is difficult to foresee, so it may lead to the backlog of ordinary shoes of a certain specification. The breathing shoes of this specification are out of stock, or vice versa, the style changes are also limited, which makes the production plan difficult, cannot be flexibly adapted to the market conditions, and the mold investment is huge. As shown 1 shows that the injection mold for the injection molded breathable shoes consists of the left and right upper wall molds. The stitched upper and the midsole are placed on the hoe of the injection mold together with the airbag or air chamber. ) The foaming liquid is injected into the mold, and the mold is closed, and after being solidified, the mold is opened and the pair of shoes are removed, and the polyurethane (PU) is injected during the injection process. The foaming liquid will block the air outlet end of the airbag in the breathing shoes, and can only wait for the manual re-drilling process after the mold is opened, and the production process is more complicated.
