具体实施方式
为了使本申请的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本申请进行进一步地详细说明。应当理解，此处所描述的具体实施例仅用以解释本申请，并不用于限定本申请。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
在本申请的描述中，需要理解的是，术语“中心”、“纵向”、“横向”、“长度”、“宽度”、“厚度”、“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”、“内”、“外”、顺时针”、“逆时针”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本申请和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本申请的限制。此外，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个所述特征。在本申请的描述中，“多个”的含义是两个或两个以上，除非另有明确具体的限定。
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，也可以是电连接或可以相互通讯；可以是直接相连，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或两个元件的相互作用关系。对于本领域的普通技术人员而言，可以根据具体情况理解上述术语在本申请中的具体含义。
在本申请中，除非另有明确的规定和限定，第一特征在第二特征之“上”或之“下”可以包括第一和第二特征直接接触，也可以包括第一和第二特征不是直接接触而是通过它们之间的另外的特征接触。而且，第一特征在第二特征“之上”、“上方”和“上面”包括第一特征在第二特征正上方和斜上方，或仅仅表示第一特征水平高度高于第二特征。第一特征在第二特征“之下”、“下方”和“下面”包括第一特征在第二特征正上方和斜上方，或仅仅表示第一特征水平高度小于第二特征。
本申请提供一种镜筒元件，镜筒元件包括主体部和多个浇口槽，主体部包括相对的第一端面和第二端面，镜筒元件设有贯穿第一端面和第二端面的收容孔，主体部的外侧具有成型面，在注塑成型时成型面用于与成型模具的分型面相接；多个浇口槽设于成型面，多个浇口槽用于分别对应于成型模具的浇注口。
如此，通过成型模具的浇注口向浇口槽射入成型材料，以获得镜筒元件，由于浇口槽位于成型面，当成型模具的公模和母模相分离时，同时分离镜筒元件及浇口槽处的成型材料的流道废料，相较于传统制作工艺：浇口材设于镜筒元件的外环面，成型模具的公模和母模相分离后，还需要进行浇口剪切处理，本申请节省了浇口槽处剪切处理的流程，节约了成本，提高成型生产的自动化和生产效率。
下文的公开提供了许多不同的实施方式或例子用来实现本申请的不同结构。为了简化本 申请的公开，下文中对特定例子的部件和设置进行描述。当然，它们仅仅为示例，并且目的不在于限制本申请。此外，本申请可以在不同例子中重复参考数字和/或参考字母，这种重复是为了简化和清楚的目的，其本身不指示所讨论各种实施方式和/或设置之间的关系。此外，本申请提供了的各种特定的工艺和材料的例子，但是本领域普通技术人员可以意识到其他工艺的应用和/或其他材料的使用。
请参见图1，图1是本申请第一实施例的一种镜筒元件100的示意图。
本实施例中，镜筒元件100为一镜筒，其可应用于电子装置中，例如手机、电脑等，也可应用于摄像模组中，例如相机。
镜筒元件100为一体成型的结构，其包括主体部10和多个浇口槽20，主体部10包括相对的第一端面12和第二端面14，主体部10设有贯穿第一端面12和第二端面14的收容孔16，主体部10的外侧具有成型面18，在注塑成型时成型面18用于与成型模具的分型面相接。多个浇口槽20设于成型面18，多个浇口槽20用于分别对应于成型模具的浇注口。
请参见图2，多个浇口槽20环绕镜筒元件100的中心轴均匀分布。
本实施例中，镜筒元件100包括四个浇口槽20，四个浇口槽20以镜筒元件100的中心轴为轴两两对称设置。
在其他实施例中，浇口槽20的数量可为多个，例如，两个、三个、五个、六个、或大于六个，保证多个浇口槽20设于成型面18上且环绕镜筒元件100的中心轴均匀分布即可，如此通过多个均匀分布的浇口槽20，使注塑成型时镜筒元件100的应力分布更为对称且平衡，有利于提升镜筒元件100均匀度和稳定性，以提升镜筒元件100的成型良率。
请参见图3，第一端面12具有第一开口122，第二端面14具有第二开口142，第一开口122和第二开口142分别位于收容孔16的相对两端，第一开口122的尺寸小于第二开口142的尺寸，如此，便于镜筒的收容孔16收容及固定镜片。
请再次参见图1至图3，第一开口122和第二开口142均为圆形，而在其他实施例中，第一开口122和第二开口142的形状可以依据实际需求设定，例如，方形、三角形、椭圆性等。
进一步地，主体部10内侧壁设有多个收容部11，每个收容部11都用于收容镜片。
本实施例中，每个收容部11为环状槽，多个收容部11从第一开口122到第二开口142方向呈阶梯状。
请参见图4，浇口槽20具有入浇口22，入浇口22与第一端面12之间的距离小于入浇口22与第二端面14之间的距离。如此，使注塑成型的镜筒元件100的结构更加均匀。
进一步地，在一实施例中，第一开口122的开口方向和入浇口22的开口方向之间的夹角可为锐角，如此，便于注塑成型时成型材料的注入。可以理解，在其他实施例中，第一开口122的开口方向可与入浇口22的开口方向平行。
请参见图5，本申请提供一种成型模具200，用于成型镜筒元件100。
成型模具200包括第一模板210和第二模板220，第二模板220和第一模板210相对设置，第二模板220具有分型面222，分型面222用于与镜筒元件100的成型面18相接。
分型面222设有多个浇注口224，每个浇注口224与镜筒元件100的浇口槽20对应设置。
如此，通过成型模具200的第一模板210和第二模板220合模以制作镜筒元件100，通过第一模板210和第二模板220分模以实现镜筒元件100与浇口槽20处的流道废物分离。
请同时参见图5和图6，第二模板220包括相连通的疏通道226和注浇道228，每个注浇道228具有浇注口224，疏通道226的延伸方向与镜筒元件100的中心轴之间的夹角小于注浇道228的延伸方向与镜筒元件100的中心轴之间的夹角。如此，通过疏通道226和注浇道228设置两个不同的角度，以节省成型模具200占用的空间。
本实施例中，第一模板210和第二模板220包括多个板状模板拼合而成，而在其他实施例中，第一模板210和第二模板220可均为一体成型结构。第一模板210和第二模板220可通过卡扣或榫卯结构可拆卸相连接。
进一步地，请参见图7，第一开口122处具有一入子300，通过疏通道226和注浇道228设置两个不同的角度，以便于将入子300镶入第一开口122。
本实施例中，疏通道226的延伸方向与镜筒元件100的中心轴平行，注浇道228的延伸方向与镜筒元件100的中心轴之间的夹角为α，其中α为锐角。可以理解地，疏通道226的延伸方向与镜筒元件100的中心轴和注浇道228的延伸方向与镜筒元件100的中心轴之间的夹角可以依据实际需求设定不同的角度，可以使疏通道226的延伸方向与镜筒元件100的中心轴小于注浇道228的延伸方向与镜筒元件100的中心轴之间的夹角，以使疏通道226和注浇道228向镜筒元件100的中心轴靠拢，以减少疏通道226和注浇道228占用的空间。当然，也可以使疏通道226的延伸方向与镜筒元件100的中心轴大于注浇道228的延伸方向与镜筒元件100的中心轴之间的夹角，以控制成型材料在疏通道226和注浇道228内的传输速度。
请参见图8，图8是本申请第二实施例的一种镜筒元件100的示意图。
本实施例中，镜筒元件100为镜片压圈，应用于镜筒元件模组中，用于将镜片固定于镜筒中。
请同时参见图8至图13，与第一实施例相似，镜筒元件100包括主体部10和多个浇口槽20，主体部10包括相对的第一端面12和第二端面14，主体部10设有贯穿第一端面12和第二端面14的收容孔16，主体部10的外侧具有成型面18，多个浇口槽20设于成型面18，不同之处在于：
请参见图10，第一开口122的尺寸大于第二开口142的尺寸且二者均为圆形，所述主体部10的外侧壁设有如图8所示的连接部13，连接部13与一镜筒的内侧壁相连接，第二端面14设有如图10所示的抵持部15，抵持部15与镜筒内的镜片相抵持，以将镜片固定于镜筒中。如此，镜片压圈呈圆环状且与大多镜片镜筒的内侧壁形状相适配，便于将镜片固定于镜筒且不影响穿过镜片的光线。
在一实施例中，连接部13通过胶水或卡槽与镜筒的内侧壁相连接。
在一实施例中，抵持部15的形状与镜片的外周面形状相适配，例如，若镜片的外周面为平面，则抵持部与第二端面14为同一平面，若镜片的外周面为凸面或凹面，则抵持部15的形状为与镜片的外周面相适配的凹部或凸部。
本实施例中，镜筒元件100包括两个浇口槽20，可以理解，浇口槽20的数量可以依据实际需求调整。
进一步地，入浇口22部分位于第一端面12，以便于后期分离镜筒元件100与浇口槽20处的成型材料的流道废料。
进一步地，疏通道226的延伸方向与镜筒元件100的中心轴之间的夹角与注浇道228的延伸方向与镜筒元件100的中心轴之间的夹角均为锐角且疏通道226的延伸方向与镜筒元件100的中心轴之间的夹角β小于注浇道228的延伸方向与镜筒元件100的中心轴之间的夹角α，其中α和β均为锐角。
本申请同时提供一种摄像模组(图未示)，摄像模组包括如上述实施例所述的镜筒元件100。
本申请同时提供一种电子设备(图未示)，包括如上述实施例所述的摄像模组。
如此，通过成型模具200的浇注口224向浇口槽20射入成型材料，以获得镜筒元件100，由于浇口槽20位于成型面18，当成型模具200的第一模板210和第二模板220分模时，同时分离镜筒元件100及浇口槽20处的成型材料的废料，节省了浇口槽20处剪切处理的流程，节约了成本，提高镜筒元件100成型生产的自动化程度和生产效率，提升摄像模组和电子设备的良率和生产效率。
对于本领域技术人员而言，显然本申请不限于上述示范性实施例的细节，而且在不背离本申请的精神或基本特征的情况下，能够以其他的具体形式实现本申请。因此，无论从哪一点来看，均应将实施例看作是示范性的，而且是非限制性的，本申请的范围由所附权利要求而不是上述说明限定，因此旨在将落在权利要求的等同要件的含义和范围内的所有变化涵括在本申请内。
以上实施例仅用以说明本申请的技术方案而非限制，尽管参照较佳实施例对本申请进行了详细说明，本领域的普通技术人员应当理解，可以对本申请的技术方案进行修改或等同替换，而不脱离本申请技术方案的精神和范围。
