Description

Technical Field

[0001] The utility model belongs to the technical field of sole moulds, in particular to a sole forming mould. Background Art

[0002] The sole usually includes all the materials that make up the bottom, such as the outsole, midsole and heel. It should be wear-resistant, water-resistant, oil-resistant, heat-resistant, pressure-resistant, impact-resistant, elastic, easy to fit the foot shape, not easy to deform after being shaped, etc. At the same time, it should have a braking effect when walking so as not to slip and be easy to stop, etc. Therefore, the sole plays a vital role in the performance of the shoe. In the production process of the sole, most of the injection molding process is used for production and processing. The sole molding mold is the mold used when the sole is obtained by injection molding, blow molding, extrusion, die casting or forging molding, smelting, stamping, stretching and other methods.

[0003] In existing sole molding molds, the upper and lower molds of the shoe mold are mostly fitted in a flat or curved shape. After long-term opening and closing, the connection between the upper and lower molds becomes loose, which easily causes displacement and misalignment between the upper and lower molds, resulting in problems such as uneven thickness, misalignment and deformation in the sole molding. The quality of the sole molding is unstable and the qualified rate of the finished product is low. Utility Model Content

[0004] The utility model aims to provide a sole forming mold in view of the above problems existing in the prior art.

[0005] The purpose of the utility model can be achieved by the following technical solutions: a sole forming mold, comprising a shoe mold upper mold and a shoe mold lower mold, wherein the fitting surfaces between the shoe mold upper mold and the shoe mold lower mold are mutually matched with each other in a wave shape when the shoe mold upper mold and the shoe mold lower mold are mutually matched, and the wave-shaped fitting surface comprises an upper mold fitting surface at the bottom of the shoe mold upper mold and a lower mold fitting surface at the top of the shoe mold lower mold when the wave-shaped fitting surface is opened; a sole convex mold is formed at the center of the upper mold fitting surface, and a sole concave mold is formed at the center of the lower mold fitting surface, and the sole convex mold and the sole concave mold are matched with each other;

[0006] The upper mold fitting surface is provided with a plurality of upper mold residual material grooves on both sides of the sole convex mold, and the lower mold fitting surface is provided with a plurality of lower mold residual material grooves on both sides of the sole concave mold. The upper mold residual material grooves correspond to the lower mold residual material grooves, and together form a plurality of residual material openings on both sides of the fitting surface when the upper mold and the lower mold of the shoe mold are closed.

[0007] In the above-mentioned sole forming mold, an upper mold handle is installed on the outer side wall of the shoe mold upper mold on the side facing the user, and a heat insulation sleeve is provided on the upper mold handle.

[0008] In the above-mentioned sole forming mold, an injection port is provided on the outer side wall of the lower mold of the shoe mold, and the injection port is communicated with the sole concave mold.

[0009] In the above-mentioned sole forming mold, the shoe mold upper mold and the shoe mold lower mold are connected in a 180° openable and closable manner through a shoe mold hinge.

[0010] Compared with the prior art, the sole molding mold provided by the utility model designs the fitting surface between the upper mold and the lower mold of the shoe mold into a wave shape that matches each other, so that it is not easy for the upper and lower molds to be displaced after closing, thereby ensuring the stability and standardization of the sole production quality; by opening a residual material port at the fitting surface, it is convenient for the excess injection molding material to overflow evenly, thereby ensuring the integrity of the sole molding.

DETAILED DESCRIPTION

[0014] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0015] like Figure 1 to Figure 2 As shown, the shoe sole forming mold comprises a shoe mold upper mold 100 and a shoe mold lower mold 200, and the shoe mold upper mold 100 and the shoe mold lower mold 200 correspond to each other. The side of the shoe sole forming mold facing the user when in use is defined as the front side, and the side facing away from the user is defined as the rear side. A sole convex mold 110 is formed at the bottom center of the shoe mold upper mold 100, and a sole concave mold 210 is formed at the top center of the shoe mold lower mold 200, and the sole convex mold 110 and the sole concave mold 210 correspond to each other.

[0016] like Figure 2 As shown, the shoe mold upper mold 100 and the shoe mold lower mold 200 can achieve a 180° opening and closing connection through the shoe mold hinge 140 on the rear side. An injection port 240 is opened on the outer wall of the shoe mold lower mold 200 below the shoe mold hinge 140. The injection port 240 is connected to the sole die 210. When the sole is formed, the injection molding machine injects the injection material into the cavity formed between the sole convex mold 110 and the sole die 210 through the injection port 240.

[0017] When the shoe mold upper mold 100 and the shoe mold lower mold 200 are closed to each other, the fitting surface between the two presents a mutually matching wave shape, which presents a wave crest at the heel forming part and a wave trough at the toe forming part. The wave-shaped fitting surface makes it difficult for the shoe mold upper mold 100 and the shoe mold lower mold 200 to be displaced after closing, thereby ensuring the stability and standardization of the sole production quality. A plurality of residual material openings 230 are provided on both sides of the wave-shaped fitting surface when the shoe mold upper mold 100 and the shoe mold lower mold 200 are closed.

[0018] like Figure 1 As shown, in the state where the shoe mold upper mold 100 and the shoe mold lower mold 200 are opened to each other, the wave-shaped fitting surface includes the upper mold fitting surface 120 at the bottom of the shoe mold upper mold 100 and the lower mold fitting surface 220 at the top of the shoe mold lower mold 200. The upper mold fitting surface 120 is arranged around the shoe sole convex mold 110, and a plurality of upper mold residual material grooves 121 are opened on the upper mold fitting surface 120 on both sides of the shoe sole convex mold 110; the lower mold fitting surface 220 is arranged around the shoe sole concave mold 210, and a plurality of lower mold residual material grooves 221 are opened on the lower mold fitting surface 220 on both sides of the shoe sole concave mold 210, and the upper mold residual material grooves 121 correspond to the lower mold residual material grooves 221, and together form a plurality of residual material openings 230 when closed. The opening of the residual material openings 230 facilitates the even overflow of the excess injection molding material from both sides of the mold during the sole molding process, thereby ensuring the integrity of the sole molding.

[0019] To further explain, an upper mold handle 130 is installed on the outer side wall of the front side of the shoe mold upper mold 100, which is convenient for the user to open and close the upper and lower molds before and after the sole is formed. An insulating sleeve 131 is provided on the upper mold handle 130. Since the sole forming temperature is relatively high, the insulating sleeve 131 can effectively prevent the user from being scalded.

[0020] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0021] Although various terms are used more frequently in this article, the possibility of using other terms is not excluded. These terms are used only to more conveniently describe and explain the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
