Description

Technical Field

[0001] The utility model relates to the technical field of shoe material molds, in particular to a forming mold for a double-layer sole. Background Art

[0002] At present, when soles are produced, the sole materials such as cast polyurethane elastomer or thermoplastic polyurethane elastomer are generally injected into the sole molding mold through an injection molding machine. After a period of aging, the mold is opened to produce the sole. At present, most of the soles are single-layer sole molds. When producing double-layer soles, they are usually produced in layers and then the two layers of soles are pasted together, thereby reducing the production efficiency of the double-layer soles.

[0003] Moreover, the existing sole molds cannot adjust the thickness of the soles. When producing double-layer soles, users sometimes set functional components between the two layers of soles, such as arch support plates, heel elastic blocks, etc. Different functional components have different shapes, and the sole shape needs to be pre-designed. The existing multi-layer sole molds do not have the conditions for adjusting the shape, which reduces their practicality. Utility Model Content

DETAILED DESCRIPTION

[0017] The utility model is further described below in conjunction with the accompanying drawings:

[0018] like Figures 1 to 3As shown, the present embodiment provides a forming mold for a double-layer sole, comprising a first movable mold 1, a second movable mold 2 and a fixed mold 3 which are arranged in sequence from top to bottom, the first movable mold 1 is provided with a first runner 101, the fixed mold 3 is provided with a second runner 301, a replaceable forming plate 201 is provided in the middle of the second movable mold 2, the top of the forming plate 201 and the first movable mold 1 form a first forming cavity, the bottom of the forming plate 201 and the fixed mold 3 form a second forming cavity, a mounting ring 202 is fixed to the outer periphery of the forming plate 201, a horizontal positioning hole 203 is opened on the side wall of the mounting ring 202, the second movable mold 2 is provided with a through hole 204 aligned with the positioning hole 203, corresponding through holes 204 and positioning holes 203 are penetrated with positioning strips 205, the forming mold for the double-layer sole of the present embodiment has high versatility and can form multi-layer soles of different thicknesses and shapes.

[0019] In this embodiment, a mounting hole is provided in the middle of the second movable mold 2, a limiting step 206 is provided in the mounting hole, the mounting ring 202 is placed on the limiting step 206, and the through hole 204 is opened on the limiting step 206. By inserting or removing the positioning strip 205, the molding plate 201 can be fixed or disassembled.

[0020] In this embodiment, the first movable mold 1 and the second movable mold 2 are movably installed above the fixed mold 3 in the vertical direction. A plurality of guide pillars 302 are provided on the top of the fixed mold 3. The first movable mold 1 is slidably fitted on the guide pillars 302. The second movable mold 2 is slidably fitted on the guide pillars 302 through a horizontal moving mechanism.
