Problems solved by technology

Usually, the bottom layer of a good-quality heel top is required to have good wear resistance and a certain degree of flexibility. During use, the nail bar and the top skin fall off, but the heel top skin produced by the injection molding machine currently used is integrally injection-molded, and it is difficult to make the heel top skin reach the wear resistance and flexibility of the lower layer due to the integral injection molding of the heel top skin. The upper layer has the performance requirements of better hardness and strength
Simultaneously, the heel skin that adopts this injection molding method is usually one color, nothing new, it is difficult to increase the interest of female friends

Embodiment 1

[0027] Embodiment 1: The present invention is a kind of heel top leather engraving processing method, and the steps are as follows:

[0028] 1). The top skin nail caps 31 are pre-buried in the heel top skin mold cavity at a certain distance, and two or more mixtures of different strengths, hardnesses, and colors are poured in successively. Enter in the mold cavity, make the heel top blank, the heel top blank can be a single blank 4 that is larger than the size of the finished heel top 6,7, or a whole piece of blank plate 5;

[0029] 2). The mold used can be as follows image 3 As shown, there are several open heel tops single cavity 1 arranged neatly arranged at certain intervals. The bottom of the cavity 1 is provided with a perforation, the nail rod 32 passes through the perforation, and the nail cap 31 is pre-embedded in the single cavity 1;

[0030] 3). The mold used can be as follows figure 1 As shown, an integral mold cavity 2 with a large area and an open mouth is pr...

Embodiment 2

[0035] Embodiment two: if adopt the mode of injection molding, 1). The top skin nail cap 31 is pre-buried in the heel top skin mold cavity at a certain interval, adopts the mode of injection molding successively, respectively puts two or more different Strength and hardness, and the mixture of different colors are injected into the mold cavity to make the heel top blank. The heel top blank can be a single blank 4 that is larger in size than the finished heel top 6, 7, or it can be A whole piece of blank plate 5;

[0036] 2). Two or more mixed raw materials are used, and each mixed raw material is first liquefied and processed in a reactor at high temperature, and then input into the barrel of the injection molding machine;

[0037] 3). Through the engraving method of the numerical control machine tool, the engraving knife engraves the heel top 6 and 7 of the required size and specifications on the single blank 4 of the heel top or the whole blank plate 5 around the top nail. ...

Abstract

The invention relates to a method for engraving heel lifts. The method comprises the following steps of: pre-embedding the heads of lift nails into a heel-lift die cavity at certain intervals; respectively successively injecting or filling two or more types of mixtures different in strength, hardness and color into the die cavity by adopting two or more injection molding machines or filling machines so as to manufacture a single blank or a whole piece of blank plate; and then, engraving lifts into required shapes and sizes by using an engraving machine. The hardness and strength of a manufactured heel lift are good, and the heel lift can be articulated with a lift nail more firmly so as to prevent the heel lift from separating from the lift nail; the bottom layer of the heel lift is made of materials which are good in anticorrosive performance and flexibility, thereby improving the abrasion resistance and comfortableness of the heel lift; and through adding pigments of different colors, heel lifts with multiple types of different color combinations can be produced, thereby increasing the aesthetic property of the heel lift, enriching heel products and satisfying the favors of women. When a small batch of many types of heel lifts are produced, the method does not need to adopt many molds; and when a large batch of heel lifts are produced, the number of molds can be increased.

Description

technical field [0001] The invention relates to the field of shoe material processing, in particular to a method for carving and processing shoe heels. Background technique [0002] The heel skin is a layer of wear-resistant skin that can be removed and replaced to prevent wear and tear on the heel of women's high-heeled shoes. Its structure is composed of a nail rod and a wear-resistant skin. In the sky skin, during production, a set of molds makes multiple heel skin mold cavities. Before injection molding, the end of the nail rod with the nail cap piece is pre-placed in the sky skin mold cavity, and then the injection molding machine is aligned with the mold. The water inlet is injection molded, and the mold cavity of the sky skin is filled with plastic liquid and then solidified. Usually, the bottom layer of a good-quality heel top is required to have good wear resistance and a certain degree of flexibility. During use, the nail bar and the top skin fall off, but the he...
