根据本申请的各种实施例，还提供上述可拆卸式鞋楦的制备方法，该制备方法操作简单，成本更低。
一种可拆卸式鞋楦的制备方法，包括以下步骤：制备楦芯：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，分别得到前掌部、后跟部及鞋帮过渡件；装配：将鞋帮过渡件与前掌部、后跟部进行组装；再将分隔片夹在前掌部和后跟部之间，并通过连接组件将前掌部和后跟部连接在一起；将夹持件插设在前掌部和后跟部之间的V型槽中，并通过螺栓与前掌部锁紧，得到楦芯；注塑：将塑胶材料加入注塑机进行加热溶解，将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：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，切削后的鞋楦粗胚露出分隔片，即可得到可拆卸式鞋楦。
在其中一个实施例中，在将夹持件进行装配前，将分隔片夹放置在V型槽中，将夹持件与前掌部及后跟部分隔开。
 有益效果
本申请通过鞋楦拆分为前掌部、后跟部、鞋帮过渡件及楦壳这四部分；鞋帮过渡件与前掌部可拆卸连接，通过鞋帮过渡件的更换来改变鞋楦的鞋型；而楦壳包裹住前掌部、后跟部及鞋帮过渡件，通过楦壳的外形来改变鞋楦的码数，这样既满足不同鞋型和鞋码的需求，同时节约了成本和提高鞋楦的利用率。
其次，在前掌部和后跟部之间设有分隔片，方便在后续切削加工过程中对楦壳进行分离，其断面可通过分隔片进行分离，切面完整，提高鞋楦外形及尺寸的完整性，使制作出来的鞋更舒适、更贴合脚型。
另外，在前掌部和后跟部之间设有夹持件，通过夹持件可以将鞋楦更好地固定在器械上，由于夹持件并非安装在塑料楦壳上，不会对鞋楦的外形造成损坏。
最后，本申请的可拆卸式鞋楦的制备方法工序不复杂，操作简单，且成本较低。

 本发明的实施方式
为了便于理解本发明，下面将对本发明进行更全面的描述。但是，本发明可以以许多不同的形式来实现，并不限于本文所描述的实施例。相反地，提供这些实施例的目的是使对本发明的公开内容的理解更加透彻全面。
除非另有定义，本文所使用的所有的技术和科学术语与属于本发明的技术领域的技术人员通常理解的含义相同。本文中在本发明的说明书中所使用的术语只是为了描述具体的实施例的目的，不是旨在于限制本发明。
请参考图1至图5，为本发明的第一实施例的可拆卸式鞋楦，为高帮鞋鞋楦。通过鞋楦拆分为楦芯（包括前掌部和后跟部）、鞋帮过渡件和楦壳这三部分，鞋帮过渡件与楦芯可拆卸连接，通过更换鞋帮过渡件来改变鞋楦的鞋型；通过楦壳来改变鞋楦的码数，这样既满足不同鞋型和鞋码的需求，同时节约了成本和提高鞋楦的利用率。
具体地，如图1至图5所示，本发明的第一实施例的可拆卸式鞋楦100，包括前掌部10、后跟部20、鞋面过渡件30、后跟过渡件40、楦壳50、分隔片60、连接组件70及夹持件80；前掌部10的下端和后跟部20的下端通过连接组件70连接；前掌部10的上端和后跟部20的上端形成V型槽（未标出），夹持件80插设于V型槽并与前掌部10锁紧；鞋面过渡件30与前掌部10连接；后跟过渡件40与后跟部20连接；分隔片60设置在前掌部10、后跟部20及夹持件80三者之间；楦壳50包裹住前掌部10、后跟部20、鞋面过渡件30及后跟过渡件40；分隔片60将楦壳50分割成若干个部分。
在本实施例中，前掌部10、后跟部20、鞋面过渡件30及后跟过渡件40均由金属制成，具体为铝或铝合金制成；前掌部10、后跟部20、鞋面过渡件30及后跟过渡件40组合形成金属楦芯。而楦壳50由塑料制成。通过将鞋楦设计成内外两层的复合式结构，通过在金属楦芯外包塑料楦壳50，金属楦芯不易损坏，可以反复利用。而塑料楦壳50可加工成不同尺寸的鞋楦，也可以通过热熔方式拆离金属楦芯，其利用成本低，步骤简单。
在本实施例中，前掌部10设有螺纹槽11，螺栓90与螺纹槽11螺纹连接，进而将夹持件80与前掌部10锁紧；另外夹持件80在顶面开设有轴孔81，侧面设有燕尾槽82。机器设备通过该燕尾槽82或轴孔81对夹持件80进行固定，进而实现了鞋楦的固定，由于夹持件80是安装在金属楦芯上，而非塑料楦壳50，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。
如图2所示，连接组件70包括两个弹性件71和两个插销72，两个弹性件71平行设置；前掌部10的内部设有两个独立容置槽（未标出），后跟部20的内部也设有两个独立容置槽（未标出），共合计为四个容置槽；弹性件71的一端插设在前掌部10的容置槽，并通过插销72与前掌部10固定连接；弹性件71的另一端插设在前掌部10的容置槽内，并通过插销72与后跟部20固定连接。弹性件71弯曲成钩状，为供前掌部10和后跟部20提滑动、合拢的阻尼。
如图3所示，鞋面过渡件30的顶端弯曲成卡接部32，卡接部32的下端面叠放于前掌部10的上端面；后跟过渡件40插设于后跟部20的上端面；前掌部10的上端设有第一切面（未标出），后跟部20的上端设有第二切面（未标出），第一切面与第二切面形成V型槽；卡接部32设有第三切面（未标出），第三切面的倾斜角度与第一切面的倾斜角度相同；后跟过渡件40设有第四切面（未标出），第四切面的倾斜角度与第二切面的倾斜角度相同。
后跟部20在其上端面设有第三卡槽22，后跟过渡件40设有第三凸块40，第三凸块40插设于第三卡槽22。
在本实施例中，分隔片60包括第一分隔片61、第二分隔片62及第三分隔片63。
第一分隔片61的下部分夹持在前掌部10与后跟部20之间；第一分隔片61的上部分与第一切面贴紧。具体为：前掌部10在第一切面的螺纹槽11两侧设有第一凸块12；第一分隔片61设有可供两个第一凸块12穿过的穿孔64；第一分隔片61通过该穿孔64与第一凸块12卡接；前掌部10在其上端面设有第一卡槽13，第一分隔片61的顶端弯曲成钩部65，钩部65与第一卡槽13卡接。
第二分隔片62的上部分与第四切面贴紧；第二分隔片62的下部分与第二切面贴紧。具体为：后跟部20自其上端面沿第二切面开设有第一插接槽21；后跟过渡件40其上端面沿第四切面开设有第三插接槽41；第二分隔片62设有第一卡接块66；第一卡接块66插设于第一插接槽21和第三插接槽41内。
前掌部10在其脚面位置设有勾形断面（未标出），前掌部10自上端面沿勾形断面开设有第二插接槽14，鞋面过渡件30设有第二卡接块31，第二卡接块31插设于第二插接槽14。
第三分隔片63与第三切面贴紧。具体为：第三分隔片63设有第二凸块67；鞋面过渡件30的卡接部32在第三切面设有第二卡槽33；第二凸块67插设于第二卡槽33。
第一分隔片61、第二分隔片62及第三分隔片63的外表面均涂覆有不沾层（图未示），这样方便在后续切削加工过程中对塑料楦壳50进行分离，其断面可通过分隔片60进行分离，切面完整，提高鞋楦外形及尺寸的完整性，使制作出来的鞋更舒适、更贴合脚型。在本实施例中，该不沾层为特氟龙层。
当然也可以通过增加分隔片60的数量来实现分离，具体表现为至少两个分隔片60叠放设置在前掌部10和后跟部20之间、前掌部10与夹持件80之间、后跟部20与夹持件80之间、鞋面过渡件30与夹持件80之间、后跟过渡件40与夹持件80之间。

在本实施例中，制备楦芯的步骤为：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，得到前掌部、后跟部、鞋面过渡件及后跟过渡件。
在本实施例中，不粘胶处理的步骤为：在第一分隔片、第二分隔片及第三分隔片的外表面涂覆特氟龙。
在本实施例中，鞋帮过渡件装配的步骤为：将鞋面过渡件和前掌部进行连接，再将后跟过渡件和后跟部进行连接；最后将第一分隔片夹在前掌部和后跟部之间，并通过连接组件将前掌部和后跟部连接在一起。
在本实施例中，夹持件装配的步骤为：将第二分隔片与后跟部及后跟过渡件进行插接，再将第三分隔片与鞋面过渡件进行连接；将夹持件插设在前掌部和后跟部之间的V型槽中，通过螺栓将夹持件与前掌部锁紧，得到楦芯。
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。

请参阅图6及图8所示，为本发明的第二实施例的可拆卸式鞋楦100a，该鞋楦100a为低帮鞋鞋楦。鞋楦100a包括前掌部10a、后跟部20a、鞋面过渡件30a、楦壳50a、分隔片60a、连接组件70a及夹持件80a；前掌部10a的下端和后跟部20a的下端通过连接组件70a连接；前掌部10a的上端和后跟部20a的上端形成V型槽（未标出），夹持件80a插设于V型槽并与前掌部10a锁紧；鞋面过渡件30a与前掌部10a连接；分隔片60a在前掌部10a、后跟部20a及夹持件80a三者之间；楦壳50a包裹住前掌部10a、后跟部20a及鞋面过渡件30a；分隔片60a将楦壳50a分割成若干个部分。
与第一实施例不同的是，本实施例的鞋帮过渡件只有鞋面过渡件30a，且鞋面过渡件30a的上端面与前掌部10a的上端面齐平。
同样地，在本实施例中，前掌部10a、后跟部20a及鞋面过渡件30a均由金属制成，具体为铝或铝合金制成；前掌部10a、后跟部20a及鞋面过渡件30a组合形成金属楦芯。楦壳50a由塑料制成，通过分隔片60a的外表面涂覆有不沾层（图未示），将楦壳50a分离开。
另外，本实施例中的连接组件70a的结构、夹持件80a的结构及其连接方式也与第一实施例相同，连接组件70a包括弹性件71a和插销72a；前掌部10a设有螺纹槽11a，螺栓90a与螺纹槽11a螺纹连接，夹持件80a在顶面开设有轴孔81a，侧面设有燕尾槽82a，具体在此不再赘述。

第一分隔片61a的下部分夹持在前掌部10a与后跟部20a之间；第一分隔片61a的上部分设置在前掌部10a与夹持件80a之间。具体为：前掌部10a在第一切面设有第一凸块12a，第一分隔片61a设有可供第一凸块12a穿过的穿孔64a，第一分隔片61a通过该穿孔64a与第一凸块12a卡接；前掌部10a在其上端面设有第一卡槽13a，第一分隔片61a的顶端弯曲成钩部65a，钩部65a与第一卡槽13a卡接。
第二分隔片62a设置在后跟部20a与夹持件80a之间。具体为：后跟部20a自其上端面沿第二切面开设有第一插接槽21a，第二分隔片62a设有第一卡接块66a，第一卡接块66a插设于第一插接槽21a内。
另外，前掌部10a在其脚面位置设有勾形断面（未标出），前掌部10a自上端面沿勾形断面开设有第二插接槽14a，鞋面过渡件30a设有第二卡接块31a，第二卡接块31a插设于第二插接槽14a。
本实施例的可拆卸式鞋楦的制备方法，包括制备楦芯、不粘胶处理、鞋帮过渡件装配、夹持件装配、注塑、冷却定型、精加工这七个步骤。
在本实施例中，制备楦芯的步骤为：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，得到前掌部、后跟部及鞋面过渡件。

在本实施例中，鞋帮过渡件装配的步骤为：将鞋面过渡件和前掌部进行连接；再将第一分隔片夹在前掌部和后跟部之间；最后通过连接组件将前掌部和后跟部连接在一起。
在本实施例中，夹持件装配的步骤为：将第二分隔片与后跟部进行插接；再将夹持件插设在前掌部和后跟部之间的V型槽中；最后通过螺栓与前掌部锁紧，得到楦芯。
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。
