Manufacturing method of environmentally-friendly insole, environmentally-friendly insole and mold for manufacturing environmentally-friendly insole

The invention relates to a method for manufacturing an environmentally-friendly insole, an environmentally-friendly insole and a mold for manufacturing an environmentally-friendly insole.

Conventional insoles or soles are typically formed by injecting plastic into a mold. However, soles made of pure plastic are generally too stiff to make the wearing feel less comfortable, and the overall weight of the insole is too heavy to cause a burden on the user when walking.

In general, in order to improve comfort, cushioning or shock absorbing components, such as cushions, are often added to the insole. However, if the cushion is placed on the insole, the fixing is not easy and the overall weight is still heavy. Therefore, another type of manufacturing method is adopted. The cushioning material is placed in the mold, and the plastic is injected into the center to wrap the cushioning material, thereby improving the positioning effect of the cushioning material and reducing the weight of the insole.

However, when the plastic is injected, it will push the cushioning material to move in the mold. Therefore, the position of the cushioning material is difficult to be precise and uniform, so that it is difficult to position the cushioning material on the heel portion, and in addition, the plastic is in contact with the cushioning material. It is easy to have plastic overflow or unevenness, and it is easy to cause the buffer material to be skewed.

The main object of the present invention is to provide a method for manufacturing an environmentally-friendly insole and a An environmentally-friendly insole that allows the heel cushioning material to be positioned accurately and avoids flashing.

In order to achieve the above object, the present invention provides a method for manufacturing an environmentally-friendly insole comprising the following steps:

Preparing a mold: the mold enclosure defines a receiving space, the top of the mold protrudes toward the receiving space with a convex portion, and the mold has at least one feeding opening for the outside to communicate with the receiving space; and a leather layer is disposed: A leather layer is disposed at the bottom of the accommodating space, and the convex portion contacts the leather layer.

Injection: a plastic is injected into the accommodating space through the inlet, and the plastic material comprises plastic and plant fibers, and the plastic fills the portion of the accommodating space except the convex portion.

Molding: heating the mold to solidify the plastic and bonding the leather layers to each other, the solidified plastic forms a cushion layer, the cushion layer is formed with a through hole, the position and shape of the receiving hole and the convex portion of the mold Correspondingly, one end opening of the receiving hole is closed by the leather layer.

A buffer material is disposed: a buffer material corresponding to the shape of the receiving hole is disposed in the receiving hole.

A shoe outsole is disposed: a sole of the shoe is disposed to a side of the cushion body facing away from the leather layer, and the outsole covers the receiving hole and the cushioning material.

The invention also provides an environmentally-friendly insole comprising a cushion layer, a leather layer, a cushioning material and a shoe outsole.

The body layer is made of a plastic and has a first surface and a second surface. The plastic material comprises plastic and plant fibers, and the body layer has a capacity extending through the first surface and the second surface. Positioning the hole; the leather layer is simultaneously bonded to the body layer when the body layer is formed The first surface of the accommodating hole is shielded from the first surface; the buffer material is disposed in the accommodating hole corresponding to the accommodating hole; the sole of the shoe is disposed to the second surface of the cushion layer The receiving hole is shielded from the cushioning material and closed.

The invention further provides a mold for manufacturing an environmentally-friendly insole, comprising a bottom block, a middle block and a top block.

The central block of the middle block is hollowed out to form an accommodating space, and a leather layer is disposed between the bottom block and the middle block; the top block, the middle block and the bottom block are sequentially stacked and pivoted to each other, the top block a convex portion is protruded from a side facing the middle block, and when a leather layer is placed between the bottom block and the middle block and the top block, the middle block and the bottom block are stacked on each other, the convex portion contacts the leather Floor.

Thereby, the accommodating hole of the invention can ensure the position of the buffer material is accurate, avoid flashing, and simplify the process, and avoid the deterioration or damage of the cushioning material when the cushioning material is formed together with the plastic.
