具体实施方式
需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。下面将参考附图并结合实施例来详细说明本申请。
如图1至图7所示，本申请的实施例一提供了一种滑块，该滑块包括内衬组件10和注塑层20，内衬组件10包括内衬本体11和撑销12，内衬本体11具有凹槽111，撑销12安装在凹槽111的槽口处，撑销12位于槽口的中部以将凹槽111分为用于注塑定位的第一定位区1111和第二定位区1112。注塑层20通过注塑附着于内衬本体11上，并在注塑时通过第一定位区1111和第二定位区1112进行定位。其中，撑销12压装在凹槽111的槽口。
采用本实施例提供的滑块，通过将撑销12压装在凹槽111的槽口内，撑销12的两端分别与凹槽111的内壁贴合连接，这样便于对撑销12进行安装，不需要在凹槽111的槽口处设置有定位槽，更不需要在撑销12上设置与定位槽配合的结构，简化了撑销12和内衬本体11的制造工艺，降低了滑块的加工难度。因此，通过本实施例提供的技术方案能够解决现有技术中的滑块存在撑销的加工难度较为复杂的技术问题。本实施例对连接后的内衬本体与撑销12再进行注塑工艺，无需在注塑的过程中形成撑销导槽(如图9中的现有技术中的滑块结构)，提高了滑块的整体强度，避免撑销12在使用过程中脱落。
具体地，可以将撑销12与凹槽111的内壁焊接，以提高撑销12的设置稳定性。
需要说明的是，此处的撑销12位于槽口的中部并不是指撑销12位于槽口的正中间的位置处，而是指撑销12可以在槽口的正中间或与槽口正中间具有一定距离范围的位置处，以便于将凹槽111分割为第一定位区1111和第二定位区1112。
如图8所示，注塑模具30包括第一模具31和第二模具32。第二模具32上设置有第一定位凸起321和第二定位凸起322，第一定位凸起321和第二定位凸起322间隔设置，第一定位凸起321位于第一定位区1111内，第二定位凸起322位于第二定位区1112内，撑销12卡设在第一定位凸起321和第二定位凸起322之间，以便于对内衬组件10进行定位，便于顺利进行注塑，提高了注塑的稳定性。同时，采用这样的结构设置，不需要在内衬本体11上设置有用于定位的定位凸起或定位槽或定位孔等定位结构，不会对内衬本体11的结构强度造成影响， 有效保证了内衬本体11的耐压强度。具体地，在注塑模具30上还设置有第一流道301和第二流道302，以通过第一流道301和第二流道302完成注塑层20的注塑。
在本实施例中，内衬本体11包括基板112以及与基板112连接的连接板113，连接板113围成凹槽111，基板112围绕凹槽111的槽口的周缘设置。注塑层20包括相互连接的第一注塑部21和第二注塑部22，第一注塑部21用于注塑在连接板113上并位于凹槽111的外侧，第二注塑部22用于注塑在基板112上并包裹基板112设置。采用这样的结构设置，在注塑时，一部分注塑流体流入至连接板113处并位于凹槽111的外侧以形成第一注塑部21，另一部分注塑流体流入至基板112的上方和下方以包裹基板112设置。采用这样的注塑结构，能够便于优化内衬本体11和注塑层20的连接方式，便于使得注塑层20稳定地设置注塑在内衬本体11上。
具体地，将内衬组件10安装在注塑模具上时，基板112的两个板面均与注塑模具间隔设置，以便于使得注塑流体能够顺利包裹基板112设置，优化注塑层20的注塑结构。
在本实施例中，撑销12靠近凹槽111的槽口的一侧与基板112的底面间隔设置，撑销12靠近凹槽111的槽口的一侧位于槽口内。采用这样的结构设置，能够避免在注塑时注塑流体不流入至凹槽111内部。
在本实施例中，基板112具有相对设置的第一板面和第二板面，第一板面和第二板面与凹槽111的外壁连接，基板112上设置有注塑连通孔1121，注塑连通孔1121贯通第一板面和第二板面设置。采用这样的结构设置，能够便于在注塑时使得注塑流体能够通过注塑连通孔1121顺利流入至第一板面和第二板面处，从而便于通过注塑流体对基板112进行包裹，提高注塑的均匀性。
具体地，撑销12靠近槽口的一侧与第二板面之间的距离为H，其中，0.2mm≤H≤0.8mm。通过将H设置在上述范围内，这样能够避免H值过大避免撑销12高度过高影响不同管的连通性能，也避免了H值过小导致注塑流体流入至凹槽111内部的情况。
具体地，撑销12靠近槽口的一侧可以设置为平面。采用这样的结构设置，能够便于在注塑时对撑销12进行定位。
具体地，撑销12远离槽口的一侧可以设置为弧面。采用这样的结构设置，能够便于减小对流体的流阻。
在一个实施例中，撑销12可以为柱体结构，柱体结构的截面为多边形面或圆形。采用这样的结构设置，便于进行加工制造。
在另一实施例中，撑销12可以为圆柱，方便制造加工，同时圆柱的弧形结构也便于降低流体的阻力。
具体地，撑销12与凹槽111的内壁采用氩弧焊或激光焊进行焊接，以提高撑销12的设置稳定性。
具体地，本实施例中的内衬本体11由金属材料制成，注塑层20由非金属材料制成，通过金属材料的内衬本体11有利于保证结构的耐压强度。
在本实施例中，内衬本体11可以采用冲裁拉伸加工而成，内衬本体11上不需要设置用于注塑定位的定位通孔结构。撑销12可以采用异形棒冲裁加工而成。
本实施例中的滑块的加工过程为：首先分别加工内衬本体11和撑销12；随后，将撑销12压装在内衬本体11的凹槽111内，并在撑销12的两端与凹槽111的内壁进行焊接以形成内衬组件10；最后，将内衬组件10放入至注塑模具中，合模进行注塑，以得到滑块。
本申请的实施例二提供了一种四通阀，包括上述实施例提供的滑块。本实施例中的滑块与四通阀的阀座进行配合，以带动阀座相对于阀体来回移动以实现冷媒流动方向的切换。
从以上的描述中，可以看出，本申请上述的实施例实现了如下技术效果：内衬本体耐压强度大，加工简单，连接稳定。
需要注意的是，这里所使用的术语仅是为了描述具体实施方式，而非意图限制根据本申请的示例性实施方式。如在这里所使用的，除非上下文另外明确指出，否则单数形式也意图包括复数形式，此外，还应当理解的是，当在本说明书中使用术语“包含”和/或“包括”时，其指明存在特征、步骤、操作、器件、组件和/或它们的组合。
除非另外具体说明，否则在这些实施例中阐述的部件和步骤的相对布置、数字表达式和数值不限制本申请的范围。同时，应当明白，为了便于描述，附图中所示出的各个部分的尺寸并不是按照实际的比例关系绘制的。对于相关领域普通技术人员已知的技术、方法和设备可能不作详细讨论，但在适当情况下，所述技术、方法和设备应当被视为授权说明书的一部分。在这里示出和讨论的所有示例中，任何具体值应被解释为仅仅是示例性的，而不是作为限制。因此，示例性实施例的其它示例可以具有不同的值。应注意到：相似的标号和字母在下面的附图中表示类似项，因此，一旦某一项在一个附图中被定义，则在随后的附图中不需要对其进行进一步讨论。
在本申请的描述中，需要理解的是，方位词如“前、后、上、下、左、右”、“横向、竖向、垂直、水平”和“顶、底”等所指示的方位或位置关系通常是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，在未作相反说明的情况下，这些方位词并不指示和暗示所指的装置或元件必须具有特定的方位或者以特定的方位构造和操作，因此不能理解为对本申请保护范围的限制；方位词“内、外”是指相对于各部件本身的轮廓的内外。
为了便于描述，在这里可以使用空间相对术语，如“在……之上”、“在……上方”、“在……上表面”、“上面的”等，用来描述如在图中所示的一个器件或特征与其他器件或特征的空间位置关系。应当理解的是，空间相对术语旨在包含除了器件在图中所描述的方位之外的在使用或操作中的不同方位。例如，如果附图中的器件被倒置，则描述为“在其他器件或构造上方”或“在其他器件或构造之上”的器件之后将被定位为“在其他器件或构造下方”或“在其他器件或构造之下”。因而，示例性术语“在……上方”可以包括“在……上方”和“在…… 下方”两种方位。该器件也可以其他不同方式定位(旋转90度或处于其他方位)，并且对这里所使用的空间相对描述作出相应解释。
此外，需要说明的是，使用“第一”、“第二”等词语来限定零部件，仅仅是为了便于对相应零部件进行区别，如没有另行声明，上述词语并没有特殊含义，因此不能理解为对本申请保护范围的限制。
以上所述仅为本申请的优选实施例而已，并不用于限制本申请，对于本领域的技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本申请的保护范围之内。
