Analysis Of Relationship Between Shoe Template And Inner Template

The inner model is made up of the front and rear parts, and then extends from the front to the inside and the front of the back. Shoes tongue Inside, before reinforcement... And so on: Antiskid Lane Mouth, roll mouth, shoe eyes, eyelet Reinforcement... And so on.

The shoes must be stable, and the unstable shoes will be judged to be bad products. The instability of the floor is caused by three factors. First, the design is improper; second, improper assembly; third, improper production. Examples of improper design are usually shoe side line errors or shoe side line errors, and the last side line and bottom side line are correct, but they can't match each other, forming a ground error after the bottom matching: an example of improper assembly is that when applying the relevant filling material, the standard of the "side line" caused by the filling material is not considered. The standard side line and bottom side line are changed. The side line of the whole shoe is changed due to the wrong filling material; the improper example is due to improper placement of the bottom into the last, squeezing or skewing, causing improper bottom pressing (poor bottom die or poor base seat) and nail and angle error.

The bottom, the makeup and the iron core are the materials that make up the three in one. The three in one bottom is designed to stabilize the side line of the shoe, so that the radian of the rear part of the shoe will not change due to the load. The side line is changed, so the design of the three in one bottom must be consistent with the side line radii formed by the middle bottom, so that the three in one middle -e_..4a, l line has the accurate radian of the upper (last side line) and the bottom (bottom side line). The structure of the three in one bottom must also be solid without peeling, and the structure of the middle sole will also be different because of the different shoes. For example, the shoes with pre cushioned insoles can be made into one of the middle bottom inserts (exposed to the iron core): the rear active middle sole (3m/m thickness insole) and the shoes with the sole needs can be made, and the structure can be made into a center of iron core. Further The standard last line, which fits the bottom of the side line of the last line, matches the bottom platform of the bottom side line, which is the three necessary design for forming the steady shoes. Any design error of the project is the cause of the instability of the shoes.

The inner template is salty based on the shoe template, so there is an accurate shoe pattern, so that there can be an accurate inner template. When trying to help, it is often found that many of the shoe models will not last. In fact, the large ratio is caused by inaccuracy, inaccuracy or bad structural design.

The inner model is mostly made up of the front and rear parts, and then extends from the front to the inside because of the demand for wear and the joint structure. And so on: extended from behind: anti slip, reverse mouth, roll mouth wrap, shoes eyes, shoes eye reinforcement... And so on.

The main structure is the combination of the front and rear parts. When making the inner template, we must pay attention to the relationship between the inner and outer sides of the upper and the inside, and the elongation difference between the inner material and the shoe upper material. Generally, we choose the inner material, and try to choose a bigger elongation than the upper material, which is better than that of the upper material. It can avoid the internal factors that cause the negative burden of shaping the upper part of the shoe when molding.

The shoe pattern is the role of the outer part, and the inner template must be the role of the inner part. Therefore, when the inner template is taken, it is necessary to understand and make the difference of the width of the inner and outer girth. Generally, the thickness of the leather can be used as the gap between the inner and outer sides. For example, the thickness of the fabric is 2.0m/m thickness, and the width of the shoe is 300m/m (100m/m). The inner template should be set to 298m/m (or 98m/m). If the material in the front and back is different from the material, generally the thin and softer cloth material is used before, then the sample in the front can be added or reduced according to the difference between the inside and outside of the material and working mode. The inner template is taken from the shoe pattern, and the inner template and the shoe template have the relationship between the inside and outside.

Shoes that are usually molded by last molding (shoe last) are combined in a closed way. Shoes must be first inserted into rigid linings so that the hard lining is sealed between the surface and the inside. At this point, it is advisable to use the hot melt adhesive with hot melt characteristics.
