Embodiment 1

[0040] A waterproof shoe cover, including a shoe upper made of waterproof fabric, the sole is directly injection-molded on the upper edge by an injection molding machine, and the formed shoe sole and shoe upper are firmly bonded by using the temperature and pressure of the melt during injection molding Together.

[0041] The processing method of the waterproof shoe cover comprises the following steps:

[0042] S1. Set the finished upper on the inner mold of the injection mold, and close the outer mold; the inner mold is the inner core of the sole injection mold (ie, the mold core) that matches the upper; the inner mold and the closed outer mold form the sole together shaped injection cavity;

[0043] S2. The mold locking mechanism of the injection molding machine locks the inner mold and the outer mold of S1, and then injection molding, using the temperature and pressure of the melt glue during injection molding to firmly bond the molded sole and upper together.

[0044] In ...

Embodiment 2

[0047] Referring to Example 1, the difference from Example 1 is that the pressing boss 4 of Example 1 is changed to a pressing pin 6, and injection molding is performed twice, as image 3 and Figure 4 shown. During one injection molding, the pressing pin 6 is pressed into the cavity, forcing the vamp 2 to be close to the mold core 7. After the injection molding is completed, the pressing pin 6 returns to its original position, and the gap of the pressing pin is filled by the secondary injection molding. image 3 and Figure 4 6 injection molding ports 8 are shown schematically, Figure 4 The middle arrow indicates the injection direction.

Embodiment 3

[0049] Referring to Example 2, the difference from Example 2 is that Example 2 is changed to two-color injection molding, and plastics of different colors are used to fill the space between the pressing pins, and the mold is designed at the same time, such as the bottom mold is a two-color bottom mold, so that the sole presents a two-color effect , Greatly enhance the taste and grade of the product.

Abstract

The invention discloses a waterproof shoe cover and a processing method thereof. The processing method comprises the following steps: sleeving an injection molding inner mold by a manufactured vamp, and further combining with an outer mold, wherein the inner mold is a shoe injection molding inner core matched with the vamp; forming an injection molding cavity of a shape of a shoe by the inner moldand the combined outer mold; further fixing the inner mold and the outer mold, performing injection molding, and solidly adhering the molded shoe to the vamp through adhesive temperatures and pressure of injection molding, so as to obtain the waterproof shoe cover. By adopting the processing method, both the production efficiency is improved, and the product quality is improved, and product typescan be expanded and enriched.

Description

technical field [0001] The invention relates to the field of shoe covers and processing thereof, in particular to a waterproof shoe cover and a processing method thereof. Background technique [0002] Waterproof shoe cover is a kind of plastic product similar to the combination of rain rubber shoes and disposable plastic shoe cover. The style and structure refer to the plastic products of boots. It can be worn outside the shoes in rainy and snowy weather, which can play the role of waterproof and mud-proof, which is convenient. Wearable and easy to store and carry. Structurally speaking, shoe covers can be divided into two parts: the upper and the sole. Usually the structure and pattern of the sole are relatively fixed, while the upper is designed in various styles. The current process is to prepare the sole and upper first, and then pass high frequency The machine welds the two together. like figure 1 As shown, this is most of the preparation methods currently used in th...
