A device for integrally forming a stereoscopic vamp pattern

Abstract

A device for integrally forming a stereoscopic vamp pattern is disclosed. The device includes at least one forming mold and at least one vacuum apparatus connected to each forming mold through a pipeline. Each forming mold includes a mold base, a ceramic template and a hot-pressing seat. The device utilizes a characteristic that the ceramic material of the ceramic template itself has multiple pores and gas permeability to form uniform suction force on the ceramic surface during a vacuumizing process so that a vamp material is uniformly adsorbed to the surface of the ceramic template, thus allowing the stereoscopic pattern formed from the vamp material to be more uniform. In addition, the device has an advantage that finer and variable stereoscopic patterns can be manufactured simply by utilizing the ceramic material.

Description

technical field [0001] The invention relates to an equipment for forming surface lines of shoe uppers, in particular to a three-dimensional line forming equipment for sheet material uppers with foam layers. Background technique [0002] At present, the surface embossing manufacturing methods for shoe upper materials, such as artificial leather, include rolling method, heat transfer printing method and vacuum embossing method; the rolling method is to use a roller with a predetermined pattern on the surface to press the sheet, In order to print a predetermined pattern on the surface of the upper material, however, most of the surface patterns printed by the rolling method are continuous repeating patterns, and their styles are relatively dull, and can only be used for the transfer of coarse textures. It can't meet the diversified needs of shoe uppers in the current market. In addition, the extrusion force of the roller is relatively large. If it is used for foamed artificial ...

[0002] At present, the surface embossing manufacturing methods for shoe upper materials, such as artificial leather, include rolling method, heat transfer printing method and vacuum embossing method; the rolling method is to use a roller with a predetermined pattern on the surface to press the sheet, In order to print a predetermined pattern on the surface of the upper material, however, most of the surface patterns printed by the rolling method are continuous repeating patterns, and their styles are relatively dull, and can only be used for the transfer of coarse textures. It can't meet the diversified needs of shoe uppers in the current market. In addition, the extrusion force of the roller is relatively large. If it is used for foamed artificial leather, it is easy to damage the material structure, making the material hard and thin, which is not easy. ideal

[0003] The hot press transfer method is mainly to set a mold that can fit up and down, and set a pattern template in the mold, put the upper material in the mold, and then heat and pressurize properly, then it can be shaped like a pattern template. However, high-temperature pressing can easily change the structure of the material, and it also has the disadvantage of making the material hard and thin, and it is not suitable for foamed artificial leather.

[0004] The vacuum embossing method is to set a pattern template and use a negative pressure vacuum suction method to make the shoe upper material adsorb on the surface of the pattern template, and use the vacuum suction to transfer the pattern of the pattern template to the shoe upper material. Avoid material hardening and thickness reduction due to rolling and hot pressing, but the pattern pattern used must be provided with many small and evenly distributed ventilation holes on the top surface of the pattern area, and penetrate to the vacuum suction equipment The connected air channels make the manufacture and processing of pattern templates more troublesome, and if the ventilation holes are set too large or the vacuum suction is too large, it is easy to transfer the traces of the ventilation holes on the shoe surface, which is not ideal
