Embodiment 1

[0043] see figure 1 , a sole in-mold pressing process, comprising the following steps:

[0044] S1. Unfold the embedded gasket 4, and tear off the protective film attached at the lower end, and dip the side of the torn protective film in water. This process lasts for 2 seconds, and then place the embedded gasket 4 into the installation groove within 3;

[0045] S2. Repeatedly press the embedded gasket 4, the number of times of pressing is 10-15 times, this process needs to be completed within 15 seconds, and then the entire shoe sole 2 and the embedded gasket 4 are placed in the processing mold 1, and the entire processing mold 1 is combined mold;

[0046] S3. Clamp the entire processing mold 1 with a clamp, and continuously heat the processing mold 1. The heating temperature is maintained at 190° C., and the film pressing time is 450 seconds.

[0047] see Figure 2-5 , the sole 2 is embedded in the processing mold 1, the upper end of the sole 2 is dug with a mounting slot...

Abstract

The invention discloses a shoe sole in-mold pressing process and belongs to the technical field of shoe sole processing. The shoe sole in-mold pressing process can realize the contact between a pre-dissolving plug and water to promote the pre-dissolving plug to be gradually dissolved, so a hot melt adhesive solution in an outer protective cladding is released from an exchange hole, and the hot melt adhesive solution in the outer protective cladding is released from the exchange hole and is filled between a mounting groove and an outer protective cladding a large amount of heat can be generated by means of contact and reaction of the reducing iron powder and part of air, on one hand, flowing efficiency of the hot melt adhesive liquid can be improved by means of the heat so that the hot melt adhesive liquid can be released more uniformly, and on the other hand, with the help of ferric oxide produced in the reaction process, under the mutual attraction effect, the whole connecting guide rope and the reducing iron powder are curled up into a ball, outflow efficiency of the hot melt adhesive liquid is further improved, and meanwhile the connecting strength between the embedded gasket and the shoe sole is improved.

Description

technical field [0001] The invention relates to the technical field of shoe sole processing, and more specifically, relates to an in-mold pressing process for shoe soles. Background technique [0002] Shoes have a long history of development. About 5,000 years ago in the Yangshao culture period, the most primitive shoes made of animal skins appeared. Shoes are a tool for people to protect their feet from injury. To make the feet uncomfortable or injured, fur shoes were invented, and the shoes have developed to the present, and they have formed what they are now, and shoes of various styles and functions can be seen everywhere. [0003] To identify the quality of shoes, we need to focus on both appearance and internal indicators. Since internal indicators often need the help of testing instruments, for a consumer, it is more practical to identify the quality of shoes from the appearance. In terms of appearance, the quality of shoes is mainly judged by the quality and workma...
