复合式鞋楦及其制备方法
相关申请的交叉引用。
本申请要求于2021 年8月3日提交中国专利局、申请号为“202110887533.6”、发明名称为“复合式鞋楦及其制备方法”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及制鞋技术领域，特别是涉及复合式鞋楦及其制备方法。
 背景技术
鞋楦是鞋的母体，是鞋的成型模具。鞋楦不仅决定鞋造型和式样，更决定着鞋是否合脚，能否起到保护脚的作用。目前鞋楦的制作通过机械加工而成，强度稳定可重复使用，但是目前针对一个鞋码和鞋型指定特定的鞋楦，鞋楦的精度要求高，对鞋型要求越高的产品，对鞋楦的精度和外形要求越高，加工的精度和难道越高，成本越高，但是人们审美的趋势变化很块，鞋楦更新换代也很快，这就造成了大量鞋楦的更新换代，成本增加。
 技术问题
传统技术中的鞋楦都是由塑料注塑而成，要回收利用的过程复杂，且成本代价高；另外鞋楦在注塑过程中，将前鞋楦与跟鞋楦进行微小移动和脱离过程中，机械手的金属部分会与鞋楦直接接触，如此会对鞋楦造成损坏。
 技术解决方案
根据本申请的各种实施例，提供一种复合式鞋楦，提高了鞋楦的重复利用率，且其成本更低。
一种复合式鞋楦，包括鞋楦和夹持件，所述鞋楦包括铝楦芯和塑料楦壳；所述铝楦芯设有上端面，所述塑料楦壳通过注塑包裹住所述铝楦芯除上端面的所有区域；所述夹持件可拆卸安装在所述铝楦芯的上端面。
在其中一个实施例中，所述鞋楦为整体楦、开盖楦或者两截楦中的一种。
在其中一个实施例中，所述铝楦芯设有至少一个定位孔。
在其中一个实施例中，当所述鞋楦为两截楦时，所述两截楦的铝楦芯包括前楦体、后楦体、活动组件、弹性件、连接片及插销；所述连接片的两端通过插销分别与所述前楦体及所述后楦体固定连接；所述弹性件弯曲成钩状，弹性件的一端勾住所述连接片，弹性件的另一端通过插销与所述后楦体固定连接。
在其中一个实施例中，所述连接片支撑所述前楦体和所述后楦体的相对滑动、合拢，所述弹性件为滑动、合拢提供阻尼。
在其中一个实施例中，所述夹持件贯穿设有第一轴孔，所述后楦体贯穿设有与第一轴孔相匹配的第一螺丝孔，所述前楦体设有与第一螺丝孔相匹配的第二螺丝孔；螺栓依次穿过第一轴孔、第一螺丝孔及第二螺丝孔，螺栓将所述夹持件与所述前楦体和所述后楦体锁紧。
在其中一个实施例中，所述第一轴孔倾斜设置，所述第二螺丝孔的倾斜角度、所述第一螺丝孔倾斜角度及第一轴孔的倾斜角度相同。
在其中一个实施例中，所述夹持件在第一轴孔的两侧贯穿设有两个竖向平行的第二轴孔。
在其中一个实施例中，所述夹持件的顶部两侧面设有燕尾槽。
根据本申请的各种实施例，还提供上述复合式鞋楦的制备方法，该制备方法操作简单，成本更低。
一种复合式鞋楦的制备方法，包括以下步骤：制备铝楦芯：将铝或铝合金加热融成铝液，再将铝液倒入压铸机的内芯模具，通过水冷模式将铝液在模具凝固后出模，得到铝楦芯；注塑：将塑胶材料加入注塑机进行加热溶解，将铝楦芯放入到注塑机的模具中进行注塑包裹；冷却定型：对注塑完成的模具进行冷却，使得模具内的塑料定型，定型后的鞋楦脱模后进行二次冷却，得到鞋楦粗胚；精加工：将夹持件与鞋楦粗胚进行组装，通过夹持件将鞋楦粗胚装设在刻楦机上，对鞋楦粗胚外表面的塑胶进行切削精加工，即可得到复合式鞋楦。
在其中一个实施例中，当制备的铝楦芯为两截楦时，在注塑前，对两截楦进行装配。
在其中一个实施例中，在对鞋楦粗胚外表面的塑胶进行切削精加工之后，根据两截楦的分界线对鞋楦粗胚外表面的塑胶进行切割，最后得到复合式两截楦。
 有益效果
本申请的复合式鞋楦设计为内外两层的复合式结构，通过在铝楦芯外包塑料楦壳，铝楦芯不易损坏，可以反复利用。塑料楦壳可加工成不同尺寸的鞋楦，也可以通过热熔方式拆离铝楦芯，其利用成本低，步骤简单。通过在铝楦芯的上端面可拆卸连接有夹持件，通过夹持件可以将鞋楦更好地固定在器械上，由于夹持件是安装在铝楦芯上而非塑料楦壳，不会对鞋楦造成损坏。
本申请的复合式鞋楦的制备方法工序不复杂，操作简单，且成本较低。

请参考图1至图2，为本发明的第一实施例的复合式鞋楦，为整体鞋楦。将鞋楦设计成内外两层的复合式结构，通过在铝楦芯外包塑料楦壳，铝楦芯不易损坏，可以反复利用；而塑料楦壳可加工成不同尺寸的鞋楦，也可以通过热熔方式拆离铝楦芯，其利用成本低，步骤简单；再通过在铝楦芯的上端面可拆卸连接有夹持件，通过夹持件可以将鞋楦更好地固定在器械上，由于夹持件是安装在铝楦芯上，而非塑料楦壳，不会对鞋楦造成损坏。
具体地，如图1至图2所示，本发明的第一实施例的复合式鞋楦100，包括铝楦芯10、塑料楦壳20及夹持件40；铝楦芯10设有定位孔13，塑料楦壳20通过注塑包裹住铝楦芯10除上端面的所有区域，当铝楦芯10放入注塑机时，通过定位孔13与注塑模具固定，从而实现塑料楦壳20与铝楦芯10的精确注塑成型；夹持件40可拆卸安装在铝楦芯10的上端面，夹持件40内部贯穿设有第一轴孔42，第一轴孔42垂直设置，只需将螺栓30穿过第一轴孔42与铝楦芯10连接，从而将夹持件40与铝楦芯10锁紧。这种连接方式既节省了夹持件40的制作成本，也方便了安装。
定位孔13的数量为至少一个，在本实施例中，定位孔13的数量为两个。
同样，第一轴孔42的数量为至少一个，在本实施例中，第一轴孔42的数量为两个。
在本实施例中，夹持件40的顶部两侧面设有燕尾槽41，机器设备通过该燕尾槽41对夹持件40进行夹持固定，进而实现了鞋楦的固定，这种间接夹持方式可以减少移动或夹持过程中对鞋楦带来的损害，刻楦机的机械手可以夹住与夹持件40两侧，燕尾槽41与之卡接更为牢固。
本实施例的复合式鞋楦的制备方法，包括制备铝楦芯、注塑、冷却定型及精加工四个步骤。
在本实施例中，制备铝楦芯的步骤为：将铝或铝合金加热到650度~700度，融成铝液，再将铝液倒入压铸机的内芯模具，通过水冷模式将铝液在模具凝固60秒后出模，得到铝楦芯。
在本实施例中，注塑的步骤为：首先将注塑机进行开机预热，将塑胶材料PE加入注塑机进行加热溶解2小时；将铝楦芯放入到注塑机的模具中，当模头温度达到180度~200度，进行注塑包裹。
在本实施例中，冷却定型的步骤为：对注塑完成的模具进行2分钟的冷水冷却，使得模具内的塑料定型，定型后的鞋楦脱模后放入冷水或温水中进行二次冷却，得到鞋楦粗胚。
在本实施例中，精加工的步骤为：将夹持件与鞋楦粗胚进行组装，通过夹持件将鞋楦粗胚装设在刻楦机上，对鞋楦粗胚外表面的塑胶进行切削精加工，即可得到复合式鞋楦。
请参阅图8，为本发明的第二实施例的复合式鞋楦100a，该鞋楦100a为两截楦。鞋楦100a包括铝楦芯10a、塑料楦壳20a及夹持件40a；铝楦芯10a包括前楦体11、后楦体12、弹性件14、连接片15及插销16；连接片15的两端通过插销16分别与前楦体11及后楦体12固定连接；弹性件14弯曲成钩状，弹性件14的一端勾住连接片15，另一端通过插销16与后楦体12固定连接；连接片15支撑前楦体11和后楦体12的相对滑动、合拢，弹性件14提供前楦体11和后楦体12滑动、合拢的阻尼。
在本实施例中，前楦体11的后部与后楦体12的前部具有相互吻合的断面（未标示），断面呈阶梯状。通过阶梯状的断面来限位，可以有效防止前楦体11和后楦体12上下错位，并且能匹配前楦体11与后楦体12快速装配定位，提高了制鞋效率。
在本实施例中，前楦体11内部设有一个第一定位孔110，,后楦体12的内部也设有一个第二定位孔120，塑料楦壳20a通过注塑方式包裹住前楦体11和后楦体12。当然，第一定位孔110及有第二定位孔120的数量也可以进行调整为多个。
在本实施例中，夹持件40a内部贯穿设有第一轴孔42a，后楦体12贯穿设有与第一轴孔42a相匹配的第一螺丝孔17，前楦体11设有与第一螺丝孔相匹配的第二螺丝孔18；螺栓30依次穿过第一轴孔42、第一螺丝孔17和第二螺丝孔18，将夹持件40a、前楦体11和后楦体12三者锁紧。
在本实施例中，第一轴孔42a倾斜设置，第二螺丝孔18的倾斜角度、第一螺丝孔17倾斜角度和第一轴孔42a的倾斜角度相同。
虽然鞋楦是两截式结构，但是夹持件40a无需因此而分割成两块。只需要在前楦体11和后楦体12开设有连通的第一螺丝孔17和第二螺丝孔18，通过螺栓30依次穿过第一轴孔42、第一螺丝孔17和第二螺丝孔18，将夹持件40a、前楦体11和后楦体12三者锁紧。这种连接方式既节省了夹持件40a的制作成本，也方便了安装。
在本实例中夹持件40a在第一轴孔42a的两侧贯穿设有两个竖向平行的第二轴孔43，机器设备通过第二轴孔43与夹持件40a连接；进而实现了鞋楦的固定，这种间接夹持方式可以减少移动或夹持过程中对鞋楦带来的损害。
本实施例的复合式鞋楦的制备方法，包括制备铝楦芯、注塑、冷却定型、精加工及切割五个步骤。
在本实施例中，制备铝楦芯的步骤为：将铝或铝合金加热到650度~700度，融成铝液，再将铝液倒入压铸机的内芯模具，通过水冷模式将铝液在模具凝固60秒后出模，得到前楦体和后楦体；通过活动组件将前楦体和后楦体进行组装，获得铝楦芯。
在本实施例中，注塑的步骤为：首先将注塑机进行开机预热，将塑胶材料PE加入注塑机进行加热溶解2小时；将铝楦芯放入到注塑机的模具中，当模头温度达到180度~200度，进行注塑包裹。
在本实施例中，冷却定型的步骤为：对注塑完成的模具进行2分钟的冷水冷却，使得模具内的塑料定型，定型后的鞋楦脱模后放入冷水或温水中进行二次冷却，得到鞋楦粗胚。
在本实施例中，精加工的步骤为：将夹持件与鞋楦粗胚进行组装，通过夹持件将鞋楦粗胚装设在刻楦机上，对鞋楦粗胚外表面的塑胶进行切削精加工，即可得到加工后的鞋楦。
在本实施例中，切割的步骤为：根据前楦体和后楦体的分界线对加工后的鞋楦外表面的塑胶进行切割，最后得到复合式鞋楦。
请参阅图6，为本发明的第三实施例的复合式鞋楦100b，该鞋楦100b为整体楦，其包括铝楦芯10b、塑料楦壳20b及夹持件40b；铝楦芯10b设有上端面，铝楦芯10b除上端面以外的区域包裹有塑料楦壳20b，夹持件40b可拆卸安装在铝楦芯10b的上端面。
在本实施例中，夹持件40b开设有第一轴孔42b和第二轴孔43b，只需将螺栓（图未示）穿过第一轴孔42b与铝楦芯10b连接，从而将夹持件40b与铝楦芯10b锁紧。这种连接方式既节省了夹持件40b的制作成本，也方便了安装；机器设备通过第二轴孔43b与夹持件40b连接；进而实现了鞋楦的固定，这种间接夹持方式可以减少移动或夹持过程中对鞋楦带来的损害。
制备本实施例的复合式鞋楦的方案与第一实施例的方法相同，在此不再进行赘述。
本发明的复合式鞋楦的第四实施例，鞋楦为两截楦。鞋楦包括铝楦芯、塑料楦壳及夹持件；铝楦芯设有上端面，铝楦芯除上端面以外的区域包裹有塑料楦壳，夹持件可拆卸安装在铝楦芯的上端面。
在本实施例中，夹持件顶端的两侧面设有燕尾槽，机器设备通过该燕尾槽对夹持件进行夹持固定，进而实现了鞋楦的固定，这种间接夹持方式可以减少移动或夹持过程中对鞋楦带来的损害。
制备本实施例的复合式鞋楦的方案与第二实施例的方法相同，在此不再进行赘述。
在以上实施例中，铝楦芯除了可以采用铝制成，还可以采用铝合金或其它轻质量金属制成；而作为连接紧固作用的螺栓，也可以通过螺钉或铆钉代替，螺栓穿过夹持件后与铝楦芯螺纹连接。
以上所述实施例仅表达了本发明的一种实施方式，其描述较为具体和详细，但并不能因此而理解为对发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。因此，本发明专利的保护范围应以所附权利要求为准。
