Embodiment Construction
[0017] The present invention is a brush-free glue-free molding process for uppers and soles, and its process includes: molding of soles → injection of PU → insertion of uppers → cooling and molding.
[0018] The specific operation of the process is as follows: thicken the midsole and put it into the mold, and then spread a layer of flannelette covered with a hot-melt adhesive film on the bottom surface to form it together to complete the sole forming process, that is, the formed sole; The final sole is put into the mold cavity; then polyurethane rubber (ie PU) is injected into the inner cavity of the sole;
[0019] When the mold is working, the mold temperature: the heating temperature is 170-175 degrees, the cooling temperature is 20-25 degrees, the molding time: heating for 420-600 seconds, cooling for 450-620 seconds, that is, the mold passes through the setting machine at 170-175 degrees from normal temperature After the table is heated for 420-600 seconds, it is transferr...

The invention provides an upper and sole brush-coating-free forming technology. The upper and sole brush-coating-free forming technology comprises the following specific operation steps that firstly, an insole is roughed and put into a mold, then a layer of lint with the bottom face covered with a hot-melting glue film is laid and integrally formed, and a formed sole is obtained; secondly, the formed sole is put into a mold cavity; thirdly, polyurethane elastomer rubber is injected into an inner core concave cavity of the sole; fourthly, an upper sleeved with a last is put in, cooled and shaped; fifthly, a scrap is trimmed off, and a finished shoe is obtained. The upper and sole brush-coating-free forming technology can solve the existing problems of complex procedures, a large labor amount, a long process and a low yield due to brush coating binding, and can also avoid potential safety hazards, caused by using chemical glue liquid, of a production environment.
Description
[0001] 【Technical field】 [0002] The invention belongs to the technical field of shoemaking, and in particular relates to a brush-free glue forming process for uppers and soles. [0003] 【Background technique】 [0004] In the field of shoemaking, in the traditional shoemaking process, the molding of the upper surface and the bottom sole (generally referred to as the midsole), that is, the molding of the upper sole, is usually completed by the glue brushing process, which is complicated. , large amount of labor, long process, low output, and also involves glue potions, there are environmental safety hazards. [0005] Therefore, practitioners eagerly expect to develop a new bottom forming process, which can solve the existing problems of using glue for lamination, and can avoid safety hazards in the production environment. [0006] 【Content of invention】 [0007] The technical problem to be solved by the present invention is to provide a brush-free glue-free molding process fo...
