Description

多层式热熔连接结构鞋子的模具下模及内仁、压缩板结构 技术领域
本发明属于鞋子制造设备技术领域，特别涉及多层式热熔连接结构鞋子的模具下模及内仁、压缩板结构。
背景技术
鞋子，由鞋面与鞋底连接成鞋；鞋底本身又包含耐磨的大底，弹性的中底等等多层结构；在常规状态下，这些多层次的结构均是通过粘接、缝接等工艺进行连接；大底需要与中底粘接，鞋面需要与鞋底粘接；而这些连接工艺不仅需要将两者连接在一起，更需要保证连接层之间具有一定的连接强度，不容易剥离，因此工艺都比较复杂；传统的鞋子粘接工艺，需要经过在粘接表面上处理剂、烘干、刷胶水、烘干、刷胶水、压底、定型、冷却、、、等等沉长的流程；人工成本高，产能低；一套制鞋流程下来，需要20-25位员工，才能有良好的产出(2000双/日)；而在现代化的发展中，人工成本会越来越高，高效、速度、自动化将成为主流的最求；在这种形式下，传统多层次产品的连接结构使得连接工艺复杂，已不再适用未来的发展形式。
因此，申请人发明了一种鞋子的制造方法，在鞋面上设置插接齿，在鞋底上设置连接孔，将鞋面的插接齿插入连接孔中，然后再射出热熔连接体，使热熔连接体与插接齿连接从而将单层或多层结构的鞋底夹持固定在中间形成鞋子；在这一方法中，面对弹性鞋底时，为了避免热熔连接体变形，凹凸不平，需要用到具有压缩板组件的模具，并需要让模具具有将鞋底压缩的功能。
因此申请人提出了一种结构简单，使用方便的模具下模，具有深度调节组件可以自动调节鞋型空间的深度，其与压缩板组件配合可对鞋底进行压缩，使插接齿插入压缩孔中。
本申请背景技术的内容，仅为了更加方便的说明本申请的发明思路，发明缘由，不应将上述所有内容都看成是现有技术的说明。
发明内容
为了克服现有技术存在的不足，
本发明目的之一：提供了多层式热熔连接结构鞋子的模具下模，可以自动调节鞋型空间的深度，与压缩板组件配合可对鞋底进行压缩，并使插接齿插入压缩孔中，适用于通过该下模生产具有弹性鞋底的鞋子。
本发明解决其技术问题所采用的技术方案是：
多层式热熔连接结构鞋子的模具下模，其特征在于：所述下模设有鞋型空间，鞋型空间的底部设有可移动的鞋型空间底板，鞋型空间底板的上下移动用于调整鞋型空间的深度；鞋型空间的中部空间用于置入鞋楦内仁组件，鞋型空间的开口处设有压缩板组件；所述鞋楦内仁组件用于将鞋面与鞋底的插接体可拆装地定位装配至鞋型空间内，并使鞋底远离鞋面的一侧朝向压缩板组件；鞋楦内仁组件的远离压缩板组件的一侧与鞋型空间底板支撑定位，所述鞋楦内仁组件的外侧面与鞋型空间的侧壁滑动配合；所述压缩板组件可开合地固定设置在鞋型空间的开口处；所述压缩板组件包括有用于隔离鞋底与外部定型腔 的压缩板，所述压缩板由多板块拼装而成，拼装缝上设有用于与插接体的插接齿相对应的压缩孔。
上述技术方案中的多层式热熔连接结构鞋子的模具下模，设有鞋型空间，现有技术中的鞋型空间一般是不具有调节深度的功能的，而本申请将鞋型空间的底板，设置成可上下移动的结构，如此便可用于调整鞋型空间的深度；当鞋楦内仁组件放入鞋型空间中时，就可以通过调节鞋型空间的底板的位置，将鞋楦内仁组件向上顶；鞋型空间的开口处可开合地固定设置有压缩板组件，打开压缩板组件，可进行鞋楦内仁组件的取放；在闭合压缩板组件的状态下，向上移动鞋型空间的底板，使鞋型空间变浅，同时使鞋楦内仁组件向上移动，带动鞋底向上运动，而鞋底又被压缩板对应阻挡，这就使得弹性的鞋底被压缩，而鞋面的插接齿对应伸入压缩孔中；该下模，结构简单，使用方便，可以通过调节鞋型空间的深度，使得鞋底可以被压缩板组件压缩，使插接齿可以伸入压缩板中，进行后续的工艺步骤。
本发明目的之二：提供了一种鞋楦内仁组件，该鞋楦内仁组件可作为上述的模具下模内的鞋楦内仁组件，但主要适用于拖鞋的生产。
解决发明目的之二，所采用的技术方案是：

上述技术方案中的一种鞋楦内仁组件，设置有拖鞋内仁，前后两端均设置固定片，对应拖鞋前后两端的缺口，并通过前后两端的固定片固定左右两侧的左固定块和右固定块，使得不规则的鞋面与鞋底的插接体，装配到鞋楦内仁上后，可以通过鞋楦内仁组件形成规则的装配结构与鞋型空间进行装配、定位、限位，以保证插接体的定位精准化，降低装配误差。
本发明目的之三，提供一种压缩板组件，该压缩板组件可应用至上述的模具下模中，可自动化地开合，使用方便。
为解决本发明目的之三，所采用的技术方案是，
一种压缩板组件，其特征在于：所述压缩板组件包括有压缩板块一、压缩板块二、压缩板块三、滑槽座一、滑槽座二、侧部气缸一、侧部气缸二；滑槽座一和滑槽座二分别相对地固定在鞋型空间两端侧壁的上端面；滑槽座一和滑槽座二相对的内侧面上均沿长度方向设有滑槽；压缩板块一和压缩板块二位于滑槽座一和滑槽座二之间，压缩板块一和压缩板块二的两端分别滑动连接在滑槽座一和滑槽座二的滑槽内；侧部气缸一固定在鞋型空间两侧一侧壁的上端，侧部气缸一的推杆连接压缩板块一；侧部气缸二固定在鞋型空间两侧另一侧壁的上端；侧部气缸二的推杆连接压缩板块二；在侧部气缸一和侧部气缸二的作用下，压缩板块一和压缩板块二沿滑槽移动分离或合拢，压缩板块三为自由件，在压缩板块一和压缩板块二合拢的状态下，压缩板块三填入压缩板块一和压缩板块二之间，压缩板块一、压缩板块二和 压缩板块三的拼装为压缩板是可以的，拼装缝上对应插接齿的形状、大小、位置设有与插接齿相对应的压缩孔。
本发明的有益效果是：

本发明还公开了一种鞋楦内仁组件，可应用至上述的下模中，进行拖鞋的生产，设置有拖鞋内仁，前后两端均设置固定片，对应拖鞋前后两端的缺口，并通过前后两端的固定片固定左右两侧的左固定块和右固定块，使得不规则的鞋面与鞋底的插接体，装配到鞋楦内仁上后，可以通过鞋楦内仁组件形成规则的装配结构与鞋型空间进行装配、定位、限位，以保证插接体的定位精准化，降低装配误差。

具体实施方式
现在结合附图对本发明作进一步详细的说明。这些附图均为简化的示意图，仅以示意方式说明本发明的基本结构，因此其仅显示与本发明有关的构成。

在本申请的描述中，需要说明的是，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”应做广义理解，例如，可以是固定连 接，也可以是可拆卸连接，或一体地连接；可以是机械连接，也可以是电连接；可以直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通。对于本领域的普通技术人员而言，可以具体情况理解上述术语在本申请中的具体含义。
下面通过多个实施例，结合整个模具，对本申请的多层式热熔连接结构鞋子的模具下模及其鞋楦内仁组件、压缩组件进行详细的说明。
首先来说明一下本申请所需要生产的鞋子的具体结构，以图1中的鞋子进行示例，无论是什么鞋型，我们都可以将鞋子分为，鞋面1和鞋底2，鞋面1和鞋底2构成了鞋子的主体，传统的制造工艺，主要是将鞋面1与鞋底2粘接或者用针线缝接；而本申请的鞋子生产方法中，加入了热熔连接体3这一构件；经本申请鞋子制造方法制造出来的鞋子，均包含有鞋面1、鞋底2、热熔连接体3；当然鞋面1、鞋底2、热熔连接体3的形状都可以进行各种美观设计，图1中的形状不构成本申请鞋子形状的限制。鞋面1具有插接齿11，鞋底2具有连接孔21。插接齿11插入连接孔21中，鞋面1与鞋底2可形成插接体；然后利用热熔连接体3与插接齿11热熔连接，就可以将单层或多层结构的鞋底2夹在鞋面1与热熔连接体3之间，形成鞋子。
在进行上述的鞋子生产时，需要应用到下述的模具；而本申请具体的是保护下述模具的一种下模及一种鞋楦内仁组件和一种压缩板组件；具体说明如下：
如图2-6所示例出的模具4结构，所述模具4包括有上模、下模；
所述上模组件包括有上模顶板71、上模拉料钉板72、上模水口板73、上模定型腔板74；所述上模定型腔板74设置在上模组件靠近下模组件的一侧；上模定型腔板74位于上模水口板73下侧，上模水口板73位于上模拉料钉板72下侧，上模拉料钉板72位于上模顶板71下侧；上模顶板71上端面设有用于与射出机热熔液体输送管道连通的注射对接口75，上模定型腔板74靠近下模组件的一侧设有定型腔41，定型腔41内设有贯通上模定型腔板74的注射孔，上模水口板73设有注射槽道76，注射孔与注射槽道76连通；注射对接口75贯穿上模顶板71和上模拉料钉板72连通注射槽道76，外部热熔液体经注射对接口75进入注射槽道76经注射孔注射入定型腔41内。
所述下模设有鞋型空间，所述鞋型空间用于放置并固定住鞋面1与鞋底2的插接体，并使鞋底2远离鞋面1的一侧面朝向上模；所述上模靠近下模的一侧设有定型腔41，定型腔41内预设有用于注入热熔液体的注入通道；
合模状态下，插接齿11连通定型腔41或者插接齿11伸入定型腔41的空间中；注入通道注入热熔液体，热熔液体与插接齿11接触，热熔液体根据定型腔41合模状态下的形状冷却定型形成热熔连接体3，热熔连接体3与插接齿11热熔连接。
具体地，在上述描述中的下模，鞋型空间并不具有本申请调节深度的功能；也没有设置压缩板组件42；同时也没有设置鞋楦内仁组件5；在这种原始的模具结构中，将插接体放入鞋型空间时，就需要对鞋型空间进行精确的设计，以便鞋面1与鞋底2的插接体放入其中 后，精确的定位；同时对应不同的鞋型，需要设计不同的下模，不同的鞋型空间；在更换生产的鞋型时，需要整体更换下模，这就非常的不便，也较为浪费成本；因此我们就设计出了鞋楦内仁组件，由插接体与鞋楦内仁组件固定，再将鞋楦内仁组件5与鞋型空间固定，这样在更换鞋型时，只需要设计并更换鞋楦内仁组件5，使用将更加方便，也更加的降低成本；同时由鞋楦内仁组件5与下模的鞋型空间进行定位，也会具有更好的定位精准度，提升生产效率和生产良品率。
具体的，在上述的描述中的下模，同样不具有本申请的压缩板组件42，那么定型腔41与鞋底2直接接触并结合，当鞋底2该侧具有较大的弹性时，射出机射出的热熔液体将直接冲击鞋底2表面，导致鞋底2表面在冲击力下产生形变，在这种形变下，冷却后的热熔连接体3形状也会变形，不再平整；在这种情况下，为了适应具有弹性鞋底的鞋子的生产，需要用到压缩板组件42将弹性鞋底2与定型腔31隔开；同时压缩板组件42还应不妨碍鞋楦内仁的放入与取出，还需要不妨碍热熔连接体冷却后拆卸压缩板组件42，在具有上述功能的同时，本申请所提供的压缩板组件5，还具有自动化开合的功能。
同时，因为在鞋底2与热熔连接体3之间设置了压缩板组件42，那么如果不对鞋底2进行压缩，在将压缩板组件42从鞋底与热熔连接体之间拆卸后，鞋底2就不能紧紧的被热熔连接体3与鞋面1所紧夹，鞋面1与鞋底2的松动会带来不好的穿鞋体验。因此模具还应具有将弹性鞋底2进行压缩的功能，从而使得下模适应具有弹性鞋底2的鞋子的生产，在热熔连接体3冷却后移除压缩板，鞋底2的回弹可 以填充原压缩板组件42所占用的空间，达到鞋底2被鞋面1和热熔连接体3紧紧夹住的效果，使连接稳当。
下面对本申请所要求保护的多层式热熔连接结构鞋子的模具下模进行详细说明：
本申请公开了多层式热熔连接结构鞋子的模具下模，所述下模设有鞋型空间，鞋型空间的底部设有可移动的鞋型空间底板66(即下文的下膜板四66)，鞋型空间底板66的上下移动用于调整鞋型空间的深度；鞋型空间的中部空间用于可拆装地置入鞋楦内仁组件5，鞋型空间的开口处设有压缩板组件42；所述鞋楦内仁组件5用于将鞋面1与鞋底2的插接体可拆装地定位装配至鞋型空间内，并使鞋底2远离鞋面1的一侧朝向压缩板组件42；鞋楦内仁组件5的远离压缩板组件42的一侧与鞋型空间底板66(即下文的下膜板四66)支撑定位，所述鞋楦内仁组件5的外侧面与鞋型空间的侧壁滑动配合；所述压缩板组件42可开合地固定设置在鞋型空间的开口处；所述压缩板组件42包括有与鞋底2相对应设置的压缩板，所述压缩板由多板块拼装而成，拼装缝上设有用于与插接体的插接齿11相对应的压缩孔。
下文中提供的压缩板组件42，为一种可自动化开合的压缩板组件42；但实际上，在某些实施例中，压缩板组件42也可通过手动的可拆装式地固定至下模上；下文的具有自动化的压缩板组件42仅为压缩板组件42在下模中的一种优选的实施例，本申请下模中可使用的压缩板组件42不以此为限。
下文所述的一种鞋楦内仁组件5，也是本申请下模中的一种鞋楦内仁组件5的实施例，不应以此为限，对于不同鞋型的生产，下模的鞋楦内仁组件5也可以是不同的。
下文所述的鞋型空间底板66的传动结构，也仅为一个可行的实施例，还可通过其它的方式使得本申请的鞋型空间底板66具有上下移动的功能；均因属于本申请的保护范畴。
具体地，图2-6所示出的实施例中的模具4，为了更好的对插接体形成定位，发明人设计出了鞋楦内仁组件5，所述鞋楦内仁组件5可拆装地固定在下模上；所述鞋楦内仁组件5，用于在拆卸状态下，将所述鞋面1与鞋底2的插接体可拆装地装配固定在鞋楦内仁组件5上；所述鞋楦内仁组件5，用于在与下模装配的状态下，将插接体间接地固定在下模上。通过将插接体固定在鞋楦内仁组件5上，然后在通过鞋楦内仁组件5与鞋型空间进行定位，使得定位可以更加精确；
当然针对于不同的鞋型所具有的不同的结构特征，鞋楦内仁组件5需要进行相应的适应性变化，比如图1中所需要生产的鞋子是一种拖鞋，且该拖鞋具有前端与后端均为开口结构的结构；那么我们就可以将鞋楦内仁组件5进行以下结构设计，以适配拖鞋的装配结构；
如图6所示，所述鞋楦内仁组件5包括有拖鞋内仁51、左固定块52、右固定块53；拖鞋内仁51用于插入鞋面1与鞋底2的插接体之内，拖鞋内仁51的前后两端设有凸出于插接体的固定片511；左固定块52和右固定块53；对应固定片511均设有配合槽57，固定片511的左右两侧分别设有栓孔，左固定块52对应固定片511左侧的 栓孔设有对应的上下贯通的栓孔，右固定块53；对应固定片511右侧的栓孔设有对应的上下贯通的栓孔；左固定块52和右固定块53；从鞋面1与鞋底2的插接体的左右两侧进行合拢，固定块位于配合槽57内，通过拴柱54插入栓孔将左固定块52和右固定块53；的前后两端分别固定在拖鞋内仁51前后两端的固定片511上，鞋底2的侧面与左固定块52及右固定块53；的内侧面贴合；左固定块52、右固定块53；的外侧壁与下模组件的鞋型空间的内侧壁适配限位。通过对鞋楦内仁组件5的结构设计，使得鞋楦内仁组件5与下模组件可拆装定位，使得鞋子与鞋楦内仁组件5可拆装定位。使定位更加精确化。
在某些实施例中，图6所示例出的所述拖鞋内仁51的前端设有撑头孔，所述拖鞋内仁51的后端设有撑跟孔；所述鞋型空间底板上对应撑头孔设有撑头杆55，对应撑跟孔设有撑跟杆56。当然本申请不以此为限，撑头杆55和撑跟杆56的设置仅为定位支撑的一种实施方式，在实际的模具4设计中，还可以通过其它的方式实现鞋型空间内底面与鞋楦内仁组件5的定位支撑。
在某些实施例中，所述下模包括有下模板一61、下模板二62；、垫脚块一63、垫脚块二64、下模板三65、下模板四66、导向杆621、端部气缸一67、端部气缸二68；垫脚块一63和垫脚块二64的下端面分别相对地固定在下模板一61上表面的两侧，下模板二62；位于垫脚块一63和垫脚块二64之间，并固定在下模板一61的上表面；下模板三65下表面的两侧分别固定在垫脚块一63和垫脚块二64远离下模板一61的上表面；所述下模板二62；设有导向杆621，所述 下模板四66设置在下模板二62；的上侧，所述下模板四66设有用于与导向杆621滑动配合连接的导向孔；端部气缸一67固定在下模板四66的一端，端部气缸二68固定在下模板四66的另一端，端部气缸一67和端部气缸二68的推杆一端均固定在下模板二62上；下模板四66的上表面构成鞋型空间的内底壁，下模板三65为中空结构，垫脚块一63、垫脚块二64以及下模板三65构成鞋型空间的侧壁，下模板三65的中空结构为鞋型空间的开口部；下模板四66通过端部气缸一67和端部气缸二68的推拉、以导向杆621为导向进行上下方向的移动。通过这种结构的设置，可以调节鞋型空间的深度，在于压缩板组件42结构配合时，还能调节对鞋底2的压缩作用力。下模板四66即为鞋型空间底板，可上下移动。
在某些实施例中，所述压缩板组件42包括有压缩板块一421、压缩板块二422、压缩板块三423、滑槽座一424、滑槽座二425、侧部气缸一426、侧部气缸二427；滑槽座一424和滑槽座二425分别相对地固定在鞋型空间两端侧壁的上端面；滑槽座一424和滑槽座二425相对的内侧面上均沿长度方向设有滑槽；压缩板块一421和压缩板块二422位于滑槽座一424和滑槽座二425之间，压缩板块一421和压缩板块二422的两端分别滑动连接在滑槽座一424和滑槽座二425的滑槽内；侧部气缸一426固定在鞋型空间两侧一侧壁的上端，侧部气缸一426的推杆连接压缩板块一421；侧部气缸二427固定在鞋型空间两侧另一侧壁的上端；侧部气缸二427的推杆连接压缩板块二422；在侧部气缸一426和侧部气缸二427的作用下，压缩板块一 421和压缩板块二422沿滑槽移动分离或合拢，压缩板块三423为自由件，在压缩板块一421和压缩板块二422合拢的状态下，压缩板块三423填入压缩板块一421和压缩板块二422之间，压缩板块一421、压缩板块二422和压缩板块三423的拼装为压缩板是可以的，拼装缝上对应插接齿11的形状、大小、位置设有与插接齿11相对应的压缩孔。通过这种设置，就可以实现，压缩板组件开合的机械控制化，提高工业生产的效率。
在某些实施例中，压缩孔呈环形排列，压缩板块三423位于中部，压缩板块一421和压缩板块二422位于两侧；所述压缩板块三423的边缘设有用于合模定位抵顶的第一定位槽4231；所述定型腔41为对应压缩孔设置的环形槽道；所述定型腔41设有定位块412，所述定位块412具有内侧定位端4122，外侧定位端4123，中部定型腔适应部4121；所述定型腔41对应中部定型腔适应部4121设有缺口，所述中部定型腔适应部4121对应位于缺口中将环形槽道补充成一贯通的槽道；合模状态下，所述定型腔41与压缩板组件42结合，内侧定位端抵顶在压缩板块三423的第一定位槽4231中，外侧定位端用于抵顶在压缩板块三423左右两侧的压缩板块一421或压缩板块二422上。提升合模时的定位精度。
以上述依据本发明的理想实施例为启示，通过上述的说明内容，相关工作人员完全可以在不偏离本项发明技术思想的范围内，进行多样的变更以及修改。本项发明的技术性范围并不局限于说明书上的内容，必须要根据权利要求范围来确定其技术性范围。
