Detailed Description
Referring to fig. 1, a first embodiment of a device for rapidly removing a mold from a shoe inner cavity according to the present invention comprises a flexible bag 1 filled with particles 2, wherein the top end of the flexible bag 1 is connected to a vacuum pump 6 through an exhaust tube 8, a three-way valve 3 is connected in series to the exhaust tube 8, a first end and a second end of the three-way valve 3 are connected in series to the exhaust tube 8, and a third end of the three-way valve 3 is connected to the atmosphere. A filter screen 7 is arranged at the joint of the telescopic bag 1 and the exhaust pipe 8 to prevent the particles 2 in the bag from entering the three-way valve and the vacuum pump.
The flexible bag 1 of this embodiment is one, and its natural shape is similar to the shape of the shoe inner cavity 4.
The flexible bag 1 is made of plastic or rubber (such as silica gel), can be flexibly deformed, and has a thickness of 0.5-0.8 mm. The particles 2 are glass beads with the particle size of less than 3mm (preferably 0.4-0.6 mm) or particles of other hard materials, including metal, sand, plastic, graphite, millet and mung bean (one or more of them are mixed). The shape of the particles 2 is preferably spherical, but may be any shape thereof. The granules 2 can slide relatively in the telescopic bag 1, and the telescopic bag 1 can deform under the extrusion of the granules.
The working process of the device (namely the rapid taking method of the shoe inner cavity) is as follows:
opening the three-way valve 3 to communicate the inside of the flexible bag 1 with the outside atmosphere, wherein the flexible bag 1 is in a random deformation state; the telescopic bag is plugged into the shoe inner cavity 4, and the folds of the upper 5 are arranged, so that the upper 5 is unfolded and straightened; compacting the telescopic bag 1 (compacting the particles 2 inwards) to ensure that the space of the shoe inner cavity 4 is filled with the particles 2 in the telescopic bag 1; the three-way valve 3 is rotated to isolate the atmosphere and is communicated with a vacuum pump 6; opening the vacuum pump 6, pumping out air in the telescopic bag 1 (the vacuum degree value is based on the principle that the particles 2 in the telescopic bag can be fixed and can not slide, and the corresponding vacuum degree value can be obtained through a conventional test, generally, the vacuum degree value is low), under the external atmospheric pressure, the telescopic bag 1 is uniformly pressed towards the glass beads 2 in the bag under the action of negative pressure, the particles 2 are tightly held together, the friction force among the particles 2 is increased, the particles cannot move mutually, and under the supporting action of the particles 2, the shape of the telescopic bag 1 is fixed; the three-way valve 3 is closed, the exhaust pipe 8 is closed, the vacuum degree in the telescopic bag 1 is kept, the appearance of the telescopic bag 1 cannot change any more, and the shoe inner cavity 4 model is manufactured. After the model is taken out, the size of the model can be measured manually or by an electronic scanner, so that the size and the shape of the inner cavity of the shoe can be obtained. After the model is measured and scanned, the three-way valve 3 is opened (communicated with the atmosphere), the flexible bag 1 enters air to be softened, and the model can be continuously taken for use.
Referring to fig. 2, a second embodiment of the device for rapidly removing a mold from a shoe inner cavity according to the present invention is different from the previous embodiment in that the collapsible bag 1 of the previous embodiment is divided into a front collapsible bag 11 and a rear collapsible bag 12, the front collapsible bag 11 has a natural shape similar to the front shape of the shoe inner cavity 4, the rear collapsible bag 12 has a natural shape similar to the rear shape of the shoe inner cavity 4, and the front collapsible bag 11 and the rear collapsible bag 12 form an integrated shoe inner cavity 4. The top ends of the front telescopic bag 11 and the rear telescopic bag 12 are respectively connected with the vacuum pump 6 through an exhaust tube 8, and a three-way valve 3 and a three-way valve 9 are respectively arranged on the two exhaust tubes 8. The three-way valve 3 and a third end of a three-way valve 9 are also open to the atmosphere.
This embodiment is particularly suitable for shoes with small openings and high uppers. The working process is as follows:
and opening the three-way valve 3 to enable the front telescopic bag 11 to enter air, plugging the front telescopic bag 11 into the front part of the shoe inner cavity 4, and finishing the folds of the shoe upper 5 to enable the shoe upper 5 to be unfolded and straightened. The front collapsible bag 11 is compacted to fill the front space of the shoe cavity 4. The three-way valve 3 is rotated to isolate air and is communicated with the vacuum pump, the vacuum pump 6 is opened to pump out the air in the front telescopic bag 11, the shape of the front telescopic bag 11 is fixed, the three-way valve 3 is closed to keep the vacuum degree in the front telescopic bag 11, and the shape of the front telescopic bag 11 can not change. The shaping of the front part of the shoe inner cavity 4 is completed.
Then, according to the above process, the rear portion of the shoe cavity 4 is shaped by the rear portion collapsible bag 12.
And finally, taking out the shaped front telescopic bag 11, namely the silica gel bag 11, and the shaped rear telescopic bag 12, and splicing the shaped front telescopic bag 11 and the shaped rear telescopic bag according to the original positions to obtain a complete shoe inner cavity model.
