[0023] The working principle of the insole mold of this utility model is as follows: First, the user selects the most suitable arch pad 20 from various specifications of arch pads 123 that fit the arch adjustment groove 123 according to the shape and height of the inner arch 1210 of their own foot, and detachably installs it into the arch adjustment groove 123 on the inner arch 1210 to complete the pre-adjustment of the mold; then, the preheated customized insole is placed on the insole forming part 12 of the mold assembly 10, so that the forefoot of the insole corresponds to the forefoot part 120, the arch corresponds to the arch part 121 (including the arch pad 20 of the inner arch 1210 and the outer arch 1211), and the heel corresponds to the heel part 122; then, the user steps on the customized insole, at which time the thermoplastic part of the insole deforms under force and gradually fits the forefoot part of the insole forming part 12. 120. The shape of the arch section 121 (including the installed arch pad 20) and the heel section 122; After the customized insole cools and sets, remove the arch pad 20 and take out the molded insole from the mold base 11; At this time, the arch section 121 of the insole forms a support structure that matches the user's inner arch 1210 due to the arch adjustment groove 123 and the arch pad 20. The outer arch 1211 also maintains the shape that matches the molded part. The forefoot section 120 and the heel section 122 also fit the corresponding parts of the mold, and finally a customized insole that matches the user's foot characteristics is obtained; By replacing the arch pad 20 of different specifications, the support height and curvature of the inner arch section 121 of the insole can be flexibly adjusted to adapt to the needs of different inner arch types 1210.

[0024] Compared to existing technologies, the insole mold of this utility model features a detachable arch support 20 structure, which allows for rapid replacement and adjustment, improving production efficiency and shortening the production time of customized insoles. Users can choose the most suitable arch support 20 from various specifications based on the shape and height of their inner arch 1210, ensuring that the arch portion 121 of the insole accurately matches the user's foot characteristics, providing optimal support and comfort. This applies not only to the inner arch 1210, but also to the outer arch 1211, forefoot portion 120, and heel portion 1210. 2. It also matches the molded parts to ensure that all parts of the insole can provide appropriate support, reducing foot pressure and fatigue; users can select and install the arch support 20 according to their own needs to complete the pre-adjustment of the mold; this process is simple and quick, without the need for professional tools or complicated operations; after the user steps on the preheated insole, the insole cools and sets in a short time, which is convenient and quick; the standardized structure of the mold base 11 and the insole molded parts 12 makes the production process more standardized and consistent, reducing quality problems caused by mold differences.

[0025] Please refer to Figure 1The insole mold also includes a positioning through hole 30 on the arch adjustment groove 123 and a positioning pin 40 on the arch pad 20; the positioning pin 40 is configured to cooperate with the positioning through hole 30.

The structure of the heel outer edge groove 51 and the arch outer edge groove 52 makes the edges of the insole at the heel 122 and arch 121 smoother, avoiding sharp corners. This not only makes the insole look more beautiful, but also improves wearing comfort and reduces the rubbing caused by protruding corners. The connection structure between the heel outer edge groove 51 and the arch outer edge groove 52 makes the edge transition natural, forming a smooth curve, making the entire edge of the insole look more coordinated and professional. By setting rounded corner grooves at the heel 122, outer arch 1211 and inner arch 1210, stress concentration in these areas can be reduced, improving the structural strength and durability of the insole. Sharp edges can easily become stress concentration points, leading to wear and damage to the insole during long-term use. Rounded edges reduce the risk of cracking when the insole is subjected to external impact, especially in the heel area 122 and arch area 121, where these areas bear significant pressure during walking; therefore, the rounded corner grooves are particularly important. The structure of the rounded corner grooves 50 makes it easier to remove the molded insole from the mold after cooling and setting. The rounded edges reduce friction between the insole and the mold, reducing resistance during demolding. During demolding, the rounded edges minimize damage to the insole, ensuring its integrity and quality.
