Technical Field

The present invention relates to a method for manufacturing a dual-material midsole of a cushioning component, and more particularly, to a method for manufacturing a midsole of a lightweight cushioning component with dual hardness.

Background

The shoes not only protect the feet, but also have the function of making the user feel comfortable. The existing shoes have more exquisite effects, so that midsoles with excellent elasticity, pressure resistance, proper hardness and low density can be arranged in the shoe pieces.

However, the existing midsole still has the following disadvantages: one is a single hardness and is uncomfortable for the user. Secondly, if comfort is pursued, the elasticity is insufficient. Third, if elasticity is pursued, comfort is insufficient. And fourthly, if the comfort and the elasticity are met, the weight is heavier.

Disclosure of Invention

In view of the above-mentioned disadvantages, the present invention provides a method for manufacturing a dual-material midsole of a cushion assembly, which provides two different hardness to the midsole to enhance the comfort and elasticity and reduce the weight of the midsole.

In order to achieve the above objects, the present invention provides a method for manufacturing a dual-material midsole of a cushioning element, comprising the steps of:

providing a second material for a substrate in a mold, and covering the mold with a second upper cover after the second material enters the mold; and

molding, namely feeding the mold covered with the second upper cover into an oven, and heating the mold covered with the second upper cover at a second preset temperature for a second reaction time to foam and form the second material, and combining the second material with the substrate to form a semi-finished product; after the heating is completed, the mold covered with the second upper cover leaves the oven, and the second upper cover and the mold are separated from each other.

In one embodiment, a step of providing a first material is provided to the mold, and after the first material enters the mold, the mold is closed with a first upper cover.

In one embodiment, a zeroth molding step, the mold covered with the first upper cover enters the oven, the oven heats the mold covered with the first upper cover at a first predetermined temperature for a first reaction time to form the first material into the substrate, after the heating is completed, the mold covered with the first upper cover leaves the oven, and the first upper cover and the mold are separated from each other.

In summary, the midsole process of the cushioning component of the present invention forms midsoles of two different materials, so that the midsole of the present invention has the characteristics of light weight and dual hardness. The midsole with double hardness can provide better comfort and elasticity for users.

Detailed Description

Referring to fig. 1, the present invention provides a method for manufacturing a dual-material midsole of a cushioning component, which comprises the steps of:

step S1, a first material is provided. A first material is provided to a mold. After the first material enters the mold, the mold is closed by a first upper cover.

And step S2, forming for the zeroth time. The mold covered with the first upper cover enters an oven, and the oven heats the mold covered with the first upper cover at a first preset temperature for a first reaction time so as to form the first material into a substrate. The first predetermined temperature is 100 + -5 deg.C. The first reaction time was 90. + -. 30 minutes. After the aforementioned heating is completed, the mold covered with the first upper cover leaves the oven, and the first upper cover and the mold are separated from each other. The first material is a mixture of a raw material A and a raw material B of polyether polyol, a catalyst, a hardening agent, an antioxidant and a pigment. If the amount of the polyether polyol is 1 unit, the amount of the catalyst is 0.05-0.1 unit, the amount of the hardener is 0.005-0.05 unit, the amount of the antioxidant is 0.02-0.05 unit, and the amount of the pigment is 0-0.05 unit. The units of measurement may be units of weight or units of volume. For example, the weight units may be kilograms, grams, or pounds, and the volume units may be liters, milliliters, or cubic meters. The temperature of the raw material A and the raw material B is 35 +/-10 ℃. The first raw material is located in the first charging bucket. The ratio of the raw material A to the raw material B is 1: 0.1 to 0.5. The raw material B is polyisocyanate or polyurea ester liquid, ethyl acetate and butyl acetate. The polyurea ester solution was 1 measurement unit. Ethyl acetate is 0.3 to 1 measurement units. Butyl acetate is in the range of 0.3 to 1 measurement units.

Step S3, a second material is provided. A second material is provided to the substrate in the mold. And after the second material enters the mold, covering the mold by a second upper cover. The second material is a foamed material. The second material is expanded polystyrene or plastic Polyurethane (TPU).

And step S4, molding. And the mold covered with the second upper cover enters an oven, and the oven heats the mold covered with the second upper cover at a second preset temperature for a second reaction time so that the second material is foamed and formed and is combined with the substrate to form a semi-finished product. The second predetermined temperature is 100 + -5 deg.C. The second reaction time was 10. + -.5 minutes. After the aforementioned heating is completed, the mold covered with the second upper cover leaves the oven, and the second upper cover and the mold are separated from each other.

And step S5, demolding. And taking the semi-finished product out of the mold.

And step S6, trimming. And (3) trimming the semi-finished product, namely removing redundant burrs of the semi-finished product.

And step S7, soaking. The trimmed semi-finished product is put into a soaking liquid to perform a soaking process at a preset soaking temperature for a preset soaking time. The predetermined soaking temperature is 30 + -5 deg.C. The predetermined soaking time is 24 hours. The soaking liquid is the mixture of polyurea ester liquid, ethyl acetate and butyl acetate. The polyurea ester solution was 1 measurement unit. Ethyl acetate is 0.3 to 1 measurement units. Butyl acetate is in the range of 0.3 to 1 measurement units.

And step S8, finishing. And finishing the soaked semi-finished product to form a finished product.

In summary, the method for manufacturing the midsole of the present invention forms two midsoles made of different materials, so that the midsole of the present invention has the characteristics of light weight and double hardness. The midsole with double hardness can provide better comfort and elasticity for users.

The embodiments described above are intended to illustrate the features and effects of the invention, but not to limit the scope of the invention, and any equivalent changes and modifications made by the disclosure of the present invention may be covered by the claims below without departing from the spirit and scope of the invention.
