详细描述
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
参照图1，图1示出了本公开实施例中的一种石英容器制造方法的步骤流程图，该方法可以应用于石英容器的制造，可以包括：
步骤101，在模具的轴线与水平面成第一夹角、以及模具绕轴线以第一转速旋转的情况下，通过成型件使原材料在顶部筒体的内壁上形成第一坯体。
本实施例中，提供模具、成型件及原材料，通过模具与成型件的配合，使原材料在模具的内壁上形成容器坯体。模具包括相连接的顶部筒体和模具底部。如图2所示，图2示出了本公开实施例中的一种模具的结构示意图，模具包括顶部筒体201和模具底部202，顶部筒体201的一端与模具底部202固定连接，顶部筒体201远离模具底部202的另一端设置有开口，顶部筒体201和模具底部202组成一端开口的模具。
其中，模具安装在成型装置中，成型装置包括倾斜机构和转动机构，倾斜机构用于调整模具的倾斜角度，转动机构用于驱动模具饶轴线转动。成型装置的具体结构可参考现有技术，本实施例对此不做限制。
在石英容器的制造过程中，首先可以通过倾斜机构使模具呈倾斜状态，如图3所示，图3示出了本公开实施例中的一种模具的倾斜示意图，通过倾斜机构可以使模具的轴线203与水平面204之间成第一夹角205，第一夹角205例如可以为50度、60度和70度，第一夹角的具体值可以根据需求设置，本实施例对此不做限制。同时，可以通过转动机构驱动模具转动，使模具绕轴线203以第一转速转动，第一转速例如可以为60转每分钟、65转每分钟和70转每分钟，第一转速的具体值可以根据需求设置，本实施例对此不做限制。
本实施例中，在模具的轴线与水平面成第一夹角、以及模具绕轴线以第一转速旋转的情况下，可以通过加料装置向模具内加入原材料，如将原材料 石英砂加入至顶部筒体201的内壁上。其中，向模具内加入原材料的过程，以及原材料的组成成分可以根据需求设置，本实施例对此不做限制。
参照图4，图4示出了本公开实施例中的一种成型件的结构示意图，成型件包括第一构件401、第二构件402和定位件403，第一构件401的一端与第二构件402的第一端连接，定位件403安装在第二构件402的第二端。相应的，模具的底部(即模具底部202的底部)可以设置定位孔，在加入原材料之后，保持第一夹角不变、模具以第一转速转动，定位件403与定位孔配合，在模具的转动过程中，通过成型件使原材料在顶部筒体201的内壁上形成第一坯体。通过成型件使原材料在顶部筒体的内壁上形成第一坯体的过程可参考现有技术，本实施例对此不做限制。
步骤102，在轴线与水平面成第二夹角、以及模具绕轴线以第二转速旋转的情况下，通过成型件使原材料在模具底部的内壁上形成第二坯体。
本实施例中，在形成第一坯体之后，可以通过倾斜机构使模具的轴线203与水平面204成第二夹角，并通过转动机构使模具绕轴线以第二转速转动。第二夹角例如可以为80度、85度和90度，第二转速例如可以为50转每分钟或55转每分钟，第二夹角和第二转速的具体值可以根据需求设置，本实施例对此不做限制。
参考步骤101，在模具以第二转速转动过程中，成型件与模具配合，使剩余的原材料在模具底部202的内壁上形成第二坯体。通过成型件在模具底部的内壁上形成第二坯体的过程可参考现有技术，本实施例对此不做限制。
步骤103，通过第一坯体和第二坯体组成的容器坯体制造得到石英容器。
本实施例中，第一坯体和第二坯体组成容器坯体，在形成容器坯体之后，可以将成型装置移至熔制室，控制熔制室的真空度，通过石墨电极产生的高温电弧对容器坯体进行熔制，得到容器毛坯。在得到容器毛坯后，对容器毛坯进行切割和清洗得到石英容器。具体通过容器坯体制造得到石英容器的过程可参考现有技术，本实施例对此不做限制。
本公开实施例中，模具包括相连接的顶部筒体和模具底部，在容器坯体形成过程中，在模具与水平面成第一夹角、模具以第一转速转动时，使原材料在顶部筒体的内壁上形成第一坯体，在模具与水平面成第二夹角、模具以 第二转速转动时，使原材料在模具底部的内壁上形成第二坯体，通过第一坯体和第二坯体组成的容器坯体制造得到石英容器，可以避免原材料在重力作用下向模具底部的中心位置滑落，提高容器坯体成型率，进而提高石英容器的制造效率。
参照图5，图5示出了本公开实施例中的另一种石英容器制造方法的步骤流程图，该方法可以应用于石英容器的制造，可以包括：
步骤501，在模具的轴线与水平面成第一夹角、以及模具绕轴线以第一转速旋转的情况下，向模具中加入第一原料，通过成型件使第一原料在顶部筒体的内壁上形成第一坯体。
本实施例中，可分步向模具内加入原材料，原材料包括形成第一坯体所用的第一原料，以及形成第二坯体所用的第二原料。具体的，在模具的轴线与水平面成第一夹角、以及模具绕轴线以第一转速旋转的情况下，可以只向顶部筒体201的内壁加入第一原料，通过第一原料形成第一坯体。具体形成第一坯体的过程可参考上述举例，本实施例对此不做赘述。
可选的，第一夹角大于等于45度、且小于等于75度，以及第一转速大于等于60转每分钟、且小于等于75转每分钟。
结合上述举例，可以调节倾斜机构，使第一夹角大于等于45度、且小于等于75度，第一夹角例如45度、50度、60度、70度和75度，以及调节转动机构，使第一转速大于等于60转每分钟、且小于等于75转每分钟，第一转速例如60转每分钟、65转每分钟、68转每分钟和70转每分钟。在第一坯体的形成过程中，模具倾斜至第一夹角，并以第二转速转动，可以避免原材料(第一原料)在重力作用下向模具底部的中心位置滑落，提高容器坯体成型率，进而提高石英容器的制造效率。
在实际应用中，当模具底部为如图2所示的锥形体时，在形成第一坯体的过程中，模具内的原材料在重力作用下容易向锥形体的底部滑落，难以形成第一坯体，使得第一坯体的成型率较低。调节第一夹角位于45度至75度之间，以及调节第一转速位于60转每分钟至75转每分钟之间，可以避免原材料向锥形体的底部滑落，提高第一坯体的成型率。
步骤502，在模具的轴线与水平面成第二夹角、以及模具绕轴线以第二 转速旋转的情况下，向模具中加入第二原料，通过成型件使第二原料在模具底部的内壁上形成第二坯体。
本实施例中，在形成第一坯体，调节倾斜机构，使模具的轴线与水平面成第二夹角、以及调节转动机构，使模具绕轴线以第二转速旋转的情况下，可以向模具内加入第二原料，如直接将第二原料加入至模具底部202的内壁上。在模具的转动过程中，通过成型件使第二原料在模具底部的内壁上形成第二坯体。
可选的，第二夹角大于第一夹角，第二转速大于等于50转每分钟、且小于等于60转每分钟。
本实施例中，在形成第二坯体的过程中，可以调节模具，使第二夹角大于第一夹角，第二转速位于50转每分钟至60转每分钟之间，例如调节第二转速为50转每分钟、55转每分钟、60转每分钟，可以避免原材料向锥形体的底部滑落。
步骤503，通过第一坯体和第二坯体组成的容器坯体制造得到石英容器。
本公开实施例中，在石英容器的坯体形成过程中，设置第一夹角大于等于45度、且小于等于75度，以及设置第一转速大于等于60转每分钟、且小于等于75转每分钟，在第一坯体的形成过程中，模具倾斜至第一夹角，并以第二转速转动，可以避免原材料在重力作用下向模具底部的中心位置滑落，提高容器坯体成型率，进而提高石英容器的制造效率。同时，在形成第一坯体时，只加入形成第一坯体所用的第一原料，可以避免加入过多的原材料，降低原材料的重量，防止原材料向底部滑落，从而提高第一坯体的稳定性。
需要说明的是，对于方法实施例，为了简单描述，故将其都表述为一系列的动作组合，但是本领域技术人员应该知悉，本申请实施例并不受所描述的动作顺序的限制，因为依据本申请实施例，某些步骤可以采用其他顺序或者同时进行。其次，本领域技术人员也应该知悉，说明书中所描述的实施例均属于优选实施例，所涉及的动作并不一定都是本申请实施例所必须的。
参照图2，本实施例提供一种模具，模具的底部为锥形体。

结合上述举例，当模具的底部为锥形体时，在石英容器制造过程中，可以在顶部筒体201的内壁上形成圆筒形状的第一坯体，以及在锥形体202的内壁上形成锥形筒状的第二坯体，从而可以制造得到具有锥形筒状的底部的石英容器。模具的使用方法可参考上述举例，本实施例对此不做赘述。
可选的，顶部筒体的内壁与锥形体的内壁采用圆弧过渡连接、且锥形体底部的内侧为圆弧曲面。
如图2所示，顶部筒体201的内壁和模具底部202的内壁之间可以设置有圆弧连接段207，使顶部筒体201的内壁与模具底部202的内壁采用圆弧过渡连接。当顶部筒体201的内壁和模具底部202的内壁通过圆弧过渡连接时，制造得到的石英容器的侧壁内侧和底部内侧之间的连接位置为圆弧状，当石英容器的侧壁内侧和底部内侧采用圆弧过渡时，可以降低硅料与石英容器内壁的摩擦力度，延长容器的使用期限。
如图2所示，锥形体202的底部的内侧可以为圆弧曲面208，使锥形体202的底部的内侧为圆弧状，从而可以使制造得到的石英容器的底部为圆弧曲面。在石英容器的使用过程中，当石英容器的底部为圆弧曲面时，可以增大石英容器底部的受力面积，提高石英容器的稳定性，并且圆弧曲面可以避免石英容器的底部与其他物体硬接触，提高石英容器的耐用性。实际使用时，也可以将锥形体的外壁设置为圆弧状，以提高模具的稳定性。
可选的，锥形体底部的内侧可以为球面或椭球面。
本实施例中，锥形体底部的内侧可以为球面或椭球面，球面或椭球面可以进一步增大模具内壁的面积，从而增加制造得到的石英容器的底部的面积，提高石英容器的稳定性。
可选的，模具上可以间隔设置多个真空孔206。结合图3所示，真空孔206可以绕轴线203，均匀的设置在顶部筒体201和模具底部202上，真空 孔的具体结构和使用方法可参考现有技术，本实施例对此不做限制。
本实施例中，模具的底部为锥形体，通过具有锥形体的模具，可以制造得到具有锥形体状的底部的石英容器。
参照图4，本实施例提供一种成型件，成型件包括第一构件、第二构件和定位件。
如图4所示，第一构件401的一端与第二构件402的第一端连接，定位件403安装于第二构件402的第二端。定位件403与锥形体202的底部配合，以使第一构件401与顶部筒体201的内壁配合，成型得到第一坯体，以及使第二构件402与锥形体202的内壁配合，成型得到锥形筒状的第二坯体。

结合上述举例，定位件403用于与锥形体202配合，第一构件与第二构件的连接处成一定角度，通过第一构件401在顶部筒体201的内壁上形成第一坯体，通过第二构件402在锥形体202的内壁上形成第二坯体。同时，可以使第二构件402靠近锥形体的一侧为直线或平面，从而可以使第二构件402成型得到的第二坯体为锥形筒状的坯体。第一构件、第二构件和定位件的具体结构和形状可以根据需求设置，只需可以使得第二构件成型得到的第二坯体为锥形筒状的坯体即可。成型件和模具配合，形成第一坯体和第二坯体的过程可参考上述举例，本实施例对此不做赘述。
示例的，第一构件401靠近顶部筒体201的一侧形成有第一直壁，第二构件402靠近锥形体202的一侧形成有第二直壁，第一直壁与第二直壁相交、且成预设夹角。
例如图4所示，第一构件401和第二构件402均为圆柱体，第一构件401的轴线和第二构件402的轴线相交、且成预设角度，第一构件401靠近 顶部筒体201的一侧为直线(第一直壁)，第二构件402靠近锥形体202的一侧也为直线(第二直壁)。在石英容器的制造过程中，模具旋转，在第二构件402的作用下，可以使模具内的原材料在锥形体202的内壁上成型得到第二坯体。预设角度的大小可以根据需求设置，本实施对此不做限制。
可选的，第二构件的第二端设置有圆弧段，圆弧段与模具配合，使第二坯体的底部为圆弧曲面。
结合上述举例，第二构件402的第二端可以设置有圆弧段4021，圆弧段4021与锥形体202的内壁配合，使得成型得到的第二坯体的底部为圆弧曲面，进一步的可以使制造得到的石英容器的底部为圆弧曲面，当石英容器的底部为圆弧曲面时，可以增加石英容器的底部的受力面积，提高石英容器的稳定性，并且圆弧曲面可以避免石英容器的底部与其他物体硬接触，提高石英容器的耐用性。
