Abstract

一种注射或模压鞋专用小后掌,其第一层为支撑层,与内底连接,周边比第二层小5~6mm,第二层为增强层,第三层为连接层,增强层、连接层两层或其中一层设有豁口,该小后掌钉合后,第一层与内底、帮角有缝隙。注胶时,与帮脚之间的缝隙填入胶料,周边的豁口同时充入胶料,于是形成主体网状胶联体,从而增加了后跟胶体与小后掌的胶联,也减少了开胶现象。

Description

一种注射或模压鞋专用小后掌
技术领域
本发明涉及鞋加工领域,尤其涉及一种注射或模压鞋专用小后掌。
背景技术
注射鞋或模压鞋用传统小后掌如图1所示边缘圆滑,与内底、后跟及帮脚结合面有限,连接不牢,导致很易开胶。
发明内容
本发明的目的就是为了克服现有技术的不足,提供一种注射或模压鞋专用小后掌,减少鞋开胶现象。
本发明的目的是以下述方式实现的:
一种注射或模压鞋专用小后掌,该小后掌垂直方向上分为三层,第一层为支撑层,与内底连接,周边比第二层小5~6mm,第二层为增强层,第三层为连接层,增强层、连接层两层或其中一层设有豁口。
所述增强层或连接层设有豁口。
所述豁口位于增强层或连接层后跟部以及两侧等距距边部位。
所述豁口为“月牙”形。
所述增强层与连接层周边大小相同。
所述小后掌是由各层用钉钉合成一体。
本发明的小后掌钉合后,第一层与内底、帮角有缝隙,胶料注入填入缝隙同时,豁口也充入胶料,于是在后掌与内底、帮脚、后跟之间形成主体网状胶联体,从而增加了后跟胶体与小后掌的胶联,减少了开胶现象。
附图说明
图1传统小后掌示意图;
图2是本发明小后掌示意图;
其中,1是第一层即支撑层;2是第二层即增强层;三是第三层即连接层;4是豁口。
具体实施方式
一种注射或模压鞋专用小后掌,如图2所示,垂直方向上分为三层,第一层为支撑层1,与内底连接,周边比第二层小5~6mm,第二层为增强层2,第三层为连接层3,增强层2与连接层3设有“月牙”形豁口4,该小后掌钉合后,第一层1与内底、帮角有缝隙,这样便于胶料注入,与小后掌、帮脚、内底成一体,周边的“月牙”豁口4在注射或模压时也同时注入胶料。
需要指出的是,豁口4的形状不限于“月牙”形,可位于增强层或连接层。
所述增强层与连接层周边大小相同。
该专利小后掌用生产中的边角废料套裁而成,然后各层用钉钉合成一体,这样一是可以方便豁口加工,二是可以大大节约材料。
传统用小后掌如图1所示,边缘光滑,本发明的小后掌与传统小后掌相比,由于第一层与内底、帮脚有缝隙,及专门设置的豁口4,增大了注入胶料后胶联的结合面积,且增强层或连接层存在的豁口注入胶料后,使小后掌与后跟形成扣合连接,连接更加牢固,对开胶现象有极大的改善作用。
以上所述的仅是本发明的优选实施方式,应当指出,对于本领域的技术人员来说,在不脱离本发明整体构思前提下,还可以作出若干改变和改进,这些也应该视为本发明的保护范围。
