The module B is kept in the original position, under the action of the first spring 120 and the second spring 121, the anti-scraping layer female die 104 and the anti-scraping layer female die auxiliary part 105 are bounced off, the glue of the anti-scraping layer injection channel 119 automatically breaks away from a recovery basket in the machine, and the injected glue is kept on the male die 103 to form a semi-finished product of the sizing foot-shaped cup, namely an anti-scraping layer sheet body;
b. the module B is horizontally moved through a mechanical arm, the module A and the module C are continuously combined together, the second material injection machine moves to the position of the supporting layer feeding channel 118, and glue of the supporting layer is injected, so that the glue of the supporting layer and the glue of the anti-scraping layer are combined together;
c. after cooling and shaping, a finished product of the foot-shaped cup, namely a heel stabilizing sleeve, is formed, then the module A and the module C are loosened, the support layer female die 106 and the support layer female die first auxiliary part 107 are bounced off under the action of the third spring 122 and the fourth spring 123, the support layer feeding channel 118 is automatically separated and falls into a recovery basket in the machine, and meanwhile, the ejector pin 113 is started and moves forwards to eject the finished product, so that the finished product falls into the finished product basket.
And then translating the module B back to the original position through a robot arm, closing the modules A, B and C, and repeating the steps a, B and C to produce the next finished product.
As a preferable embodiment, after the step (4), the heel stabilizing sleeve is placed in the interlayer of the vamp and the fabric, or the heel is directly attached to the surface of the vamp, and then the shoe with the heel stabilizing sleeve is placed in a mold of a freezing forming machine for heel forming, and the shape of the heel stabilizing sleeve is ensured to be matched with that of the shoe tree.
As a preferable embodiment, in step (2), in order to prevent the shrinkage and deformation of the finished product caused by thermal expansion and contraction after the material of the supporting layer 2 is injected onto the surface of the scratch-resistant layer 1, in order to facilitate the secondary processing, the position where the scratch-resistant layer 1 is combined with the supporting layer 2 is provided with density sizing columns, the diameter of each column is 2MM, the height of each column is consistent with the thickness of the corresponding position of the scratch-resistant layer 1, the distance between each column is more than 10MM, and a plurality of density sizing columns are formed on the connecting part of the scratch-resistant layer 1, and the distance between the density sizing columns is more than 10 MM.
The utility model relates to a processing method of heel stabilizing sleeve of diabetes foot shoes, the method is simple, combines hard material (being supporting layer 2) and softwood material (being anti-scratch layer 1), is fit for the diabetes shoes and uses.
The above embodiments and drawings do not limit the form and style of the present invention, and any suitable changes or modifications made by those skilled in the art should not be considered as departing from the scope of the present invention.
