Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an insole forming mold, and more particularly to a forming mold for an insole coated with a material that is not easily deformable. BACKGROUND OF THE INVENTION With the continuous improvement of people's living standards, the quality requirements for daily necessities have been improved in order to improve the comfort of the shoe body, and the material shield of the shoe body or the insole is usually improved. Most of the active insoles are made of thermoplastic materials. They are shaped by heat and pressure and do not rebound, such as EVA, PVC, PE cotton, etc. However, due to the physical properties of the above thermoplastic materials, they are often caused by insufficient hardness. The deformation rate, that is, the wear is uncomfortable, the softness is easy to deform; if the non-deformable material is applied as the vertical force surface, and the thermoplastic material is stuck in the shoe as the unstressed side wall, the combination can be economical and Practical, but because the physical properties of the two materials are different, if the non-deformable material is rebounded after being pressed by the conventional mold, the two materials are difficult to be formed at one time, so the mold for molding the insole becomes the industry. The problem that needs to be improved. SUMMARY OF THE INVENTION The present invention is directed to the absence of the above-mentioned conventional technology, and the main object of the present invention is to provide a molding die for an insole coated with a sandwich of a non-deformable material, which can quickly and conveniently mold two different physical materials at one time. A soft insole coated with a layer of non-deformable material.

In order to achieve the above purpose, the utility model takes the following technical solutions:

An insole forming mold comprising an upper mold and a lower mold matched with the upper mold, the upper mold and the lower mold each comprise a mold body, the upper mold comprises an upper main mold, and the upper main mold is provided with the same insole shape The lower mold includes a lower main mold, and the lower main mold is provided with a side mold at a periphery thereof, and a receiving space for the interlayer of the non-deformable material is left between the upper main mold and the lower main mold when the upper mold and the lower mold are pressed together. The utility model is used for preventing the rebound of the interlayer of the non-deformable material; the concave position of the upper main mold cooperates with the side mold of the lower main mold to press the easily deformable material of the insole.

The side mold is extended upwardly and convexly provided with a wire frame higher than the lower main mold surface for quickly positioning the insole, and the wire frame cooperates with the concave position of the upper mold.

The upper main mold and the lower main mold are disposed on the mold body.

Compared with the conventional technology, the utility model has the advantages of the concave position and the lower mold set by the upper mold The side molds are arranged to form a receiving space for accommodating the non-deformable material, so that the upper mold and the lower mold are not pressed, and the deformation of the interlayer of the non-deformable material is not caused by the rebound of the non-deformable material, and the insole is further caught by the wire frame of the lower mold. The non-deformable material interlayer enables the upper and lower molds to effectively position the non-deformable material interlayer quickly before being combined with the pressing, so that two different physical materials can be formed at one time quickly and conveniently, thereby obtaining a sandwich coated with a non-deformable material.

As shown in FIG. 1 , an insole coated with a sandwich of a non-deformable material includes a bottom layer 10 and a fabric layer 20 , and the interlayer 10 and the fabric layer 20 are covered with a sandwich 30 of a non-deformable material. The deformed material may be a latex sponge, a rubber sponge or a polyurethane (PU) sponge which is difficult to mold after heating. The bottom layer is an EVA material of a deformable material, which may be a foot surface of the insole or a bottom surface of the insole.

As shown in Fig. 2, Fig. 3, and Fig. 4, a mold for forming an insole coated with a sandwich of a non-deformable material includes an upper mold 40 and a lower mold 50, wherein:

The upper mold 40 is provided with a mold body 41 which is constituted by an upper main mold 41 which is provided with a recess 43 in the shape of an insole.

The lower mold 50 is also provided with a mold body 51. The mold body 51 is formed by a lower main mold 52. The lower main mold 52 is provided with a side mold 53 at a periphery thereof, and the side mold 53 is extended upwardly and convexly higher than the lower main mold surface. A wire frame 54 for quickly positioning the insole.

The wire frame 54 of the lower main mold 52 cooperates with the concave position 43 of the upper main mold 42 in which the accommodation space of the insole interlayer capable of accommodating the non-deformable material is left to prevent the rebound of the interlayer of the non-deformable material; The side mold 53 and the concave portion 43 of the upper mold are the main portions of the extruded deformable material, wherein the wire frame 54 of the lower mold is mainly used for quickly positioning the insole clip Layer material.

The method for manufacturing the insole by the above-mentioned molding die is as follows: Firstly, the bottom layer 10 of the deformable material, the interlayer 30 of the non-deformable material, and the fabric layer 20 are sequentially laminated, and then directly placed on the lower main mold 52, The wire frame 54 is used to quickly position the non-deformable material interlayer 30 of the insole, and then directly pressed through the upper mold 40, and the bottom layer 10 and the fabric layer of the easily deformable material are pressed by the side mold 53 of the lower mold and the concave edge 43 of the upper mold. 20, the interlayer 30 of the non-deformable material is retained in the accommodating space formed by the side mold 53 of the lower main mold 52 and the concave portion 43 of the upper main mold 42, so that the interlayer of the non-deformable material is left after the mold clamping The space is accommodated without the phenomenon of pressure rebound, so that the interlayer of the non-deformable material is coated between the bottom layer 10 and the fabric layer 20, thereby completing the process of covering the insole with the non-deformable material.

The design of the utility model focuses on forming a accommodating space for accommodating the non-deformable material by the concave position provided by the upper mold and the side mold provided by the lower mold, so that the accommodating space of the non-deformable material interlayer can be prevented from being rebounded due to the accommodating space left after the mold clamping. At the same time, the wire frame of the lower mold is further clamped to the insole material deformation layer, so that the upper and lower molds can effectively position the non-changeable material interlayer quickly before the pressing, so that the two different physical materials can be quickly and conveniently Forming, and in turn, a soft insole coated with a layer of non-deformable material.

The above description is only a preferred embodiment of the molding die of the insole coated with the interlayer of the non-deformable material, and does not limit, modify, or modify the technical scope of the present invention. Within the scope of the technical solution of the present invention.
