A kind of integrally formed shock-absorbing sole or sole accessory and its production mold and production method

Abstract

The invention discloses an integrated damping sole or sole accessory which comprises an outsole, at least one damping material layer and a TPU film wrapping layer, wherein the damping material layer is pasted on the top surface of the outsole; the TPU film wrapping layer wraps the side surface of the outsole, the top surface of the outsole, the side surface of the damping material layer and the top surface of the damping material layer; the outsole, the damping material layer and the TPU film wrapping layer are integrated; and the thickness of the damping material layer is greater than that of the outsole. The outsole and damping layer of the sole are integrated in the same die, a few processes are adopted, the flow is simple, and the production cost is greatly reduced. The invention also discloses a production die of the integrated damping sole or sole accessory, wherein the die is provided with an outsole cavity and an insole cavity and can realize once casting molding of the sole; and moreover, the die is simple in structure and convenient to maintain. The invention further discloses a production method of the integrated damping sole or sole accessory, which is simple in flow, convenient to operate and efficient and safe.

Description

technical field [0001] The invention relates to the technical field of shoe accessories production, in particular to an integrally formed shock-absorbing shoe sole or shoe sole accessory, a manufacturing mold and a production method thereof. Background technique [0002] Shoes can protect people's feet well, especially, shoes can reduce or avoid the shock force that people walk or run, and avoid spinal nerves from being injured. In shoes, the sole is a key component for shock absorption. Therefore, the structure and manufacturing method of the sole are particularly important. [0003] The applicant applied for a patent in 2014: a PU elastic environmental protection shoe sole and its production method and production mold (application number: 201410277439.9). Etc. However, in the production process of the sole, at first it is necessary to utilize the large bottom mold to produce the large bottom, then the surface of the large bottom is roughened, and the adhesive is coated; ...

AI Technical Summary

Problems solved by technology

In other words, the production of the outsole and midsole needs to be carried out in different molds. To achieve the bonding of the outsole and the midsole, it is necessary to increase the process of grinding the outsole, applying treatment water, applying glue, heating and laminating. , the process is numerous, which greatly increases the production cost

[0004] In addition, I also applied for a transparent perfusion spring shock absorber in 2014 (application number: 2014208249446). This patent uses GEL gel molding shock absorber, but GEL is easy to deform, the material is brittle and easy to tear, and cannot be combined with shoes. Material bonding and other defects, in order to solve this problem, the patent uses a vacuum suction film process to attach a layer of TPU film on the surface of the GEL shock absorber. However, there is still a gap on the top of the shock absorber that is not wrapped by the TPU film. When the shock absorber is under pressure, the GEL is easy to squeeze out, which is easy to cause delamination

Moreover, the shock absorber is only molded with a single shock-absorbing material, which is not wear-resistant, and cannot directly contact and rub against the ground
