  • the injection molding material is easy to obtain, which greatly reduces product costs.
  • the plate racket formed by injection molding will not deform or delaminate when it comes into contact with water.

(三)有益效果
本发明提供了一种注塑一体成型的板式球拍。与现有技术相比，具备以下有益效果：
1、通过拍面部填充腔以及拍柄部中空结构的设置，保障注塑一体成型的板式球拍整体重量符合运动的需求，解决了注塑一体成型的板式球拍在使用过程中克量较重的问题。
2、注塑一体成型的板式球拍的拍柄部和拍面部由注塑工艺注塑一 体而成，可以大大提高生产效率和产品的一致性，而且注塑材料取材便捷，大大降低了产品成本，注塑一体成型的板式球拍，遇水不会出现变形和分层的问题，同时拍面部内部位于整个球拍中心轴线上的主轴筋将球拍均匀一分为二，位于主轴筋两侧的支撑筋与主轴筋相互交叉，和主轴筋起到了支撑拍面部的作用，而且，形成若干互不相通的独立填充腔，与拍柄部中空结构共同作用下，大幅降低球拍的重量，避免因球拍太重而影响运动成绩的发挥。支撑筋对称排列在球拍中心轴线的两侧，形成若干个填充腔对称排列在球拍中心轴线的两侧，能够有效保证球拍的平衡度。
3、球拍拍面部的整体厚度有限，像乒乓球拍的拍面部本体一般不超过10mm，所以，在球拍成型过程中，注塑模具用于形成填充腔的抽芯是一块长而簿的材料，像乒乓球拍拍面的窄面尺寸可以达到150mm，模具抽芯材料在注塑过程中容易出现变形而无法实现批量生产。因此，在拍面部内部、位于球拍中心轴线上设一主轴筋，该主轴筋与支撑筋垂直相交，有利于提升拍面部的强度。同时，位于球拍中心轴线上的主轴筋，将拍面部内部一分为二，使注塑模具的抽芯杆长度缩短一半以上，以保证注塑工艺的实现。填充腔对称排列在主轴筋两侧，可以缩短填充腔的深度，使模具结构容易实现，同时，保证球拍的重心位于球拍的中心轴线上，使球拍保持平衡而不失衡。主轴筋与支撑筋垂直相交，有利于简化模具结构，提高模具的使用寿命。
4、填充腔在内部填充发泡材料，在支撑筋、主轴筋、拍面面板和发泡材料的支撑下保证拍面部结构强度前提下，拍面部中空的填充腔结构和拍柄部的中空结构能够大幅降低注塑一体成型的板式球拍整体重量。发泡材料注入拍面部的填充腔内填充其中，以及拍柄部的中空结构内填充中空结构，不但保障球拍整体重量符合运动的需求，而且对注塑一体成型的板式球拍起到支撑，可以使球拍在不大幅增加克重的情况下，提升球拍的厚实感，使球拍有避震效果。
5、球拍重心位置是靠近拍柄部还是远离拍柄部，可以在产品设计 时进行设定，可以事先对球拍的重心位置做适当调整。如果增加靠近手柄主轴筋段落的粗度，可以提高靠近手柄段落主轴筋的克重，球拍的重心更靠近手柄；如果把远离手柄主轴筋段落的粗度加粗，那么，远离手柄主轴筋的克重加重，球拍的重心相对会向远离手柄段转移；同样的道理，可以在产品设计时，增加位于球拍中心轴线上的主轴筋各段落的支撑筋的分布密度，和或主轴筋各段落的支撑筋的粗细来实现对球拍的重心位置设定；进一步，可以在产品设计时，变化位于球拍中心轴线上的主轴筋各段落的球拍拍面填充腔上下拍面的壁厚，来实现对球拍的重心位置的设定，以满足不同的运动习惯。
6、用于封闭填充腔开口的是一封条组件，该封条组件是一注塑一次性成型的保护带，该保护带有二个面，其中一个面是平整的，另一面上有多个凸块。这些凸块的位置和尺寸正好与可设定重心位置的球拍上填空腔开口的位置和尺寸吻合。当封条组件上的各个凸块分别被嵌入各自对应的填充腔后，封条组件保护带的平整一面正好贴合在所述球拍的周边。进一步，封条组件的保护带的边沿超出所述球拍的边沿，并且齐拍面上的胶皮表面，以使球拍表面的海绵层及胶皮层的侧面也受到封条组件保护带的保护。
7、在本设置方式注塑一体成型的板式球拍是中空设置，球拍的克重得到控制，在球拍面的表面，贴上相应的海绵，再在海绵上贴合胶皮，可以进一步提升本设置方式乒乓球拍的击球效果。
8、本设置方式可广泛应用于乒乓球拍、海滩拍或板式网球拍等注塑一体成型的板式球拍。
9、为了实现垂直于中心轴线上的重心位置设定，可以两侧重心的不位于本设置方式注塑一体成型的板式球式的主轴筋二侧的支撑筋的数量
10、在本设置方式注塑一体成型的乒乓球拍是中空设置，在球拍完成注塑一体成型后，球拍两拍面贴上相应的海绵和胶皮后，如果还需要对球拍重心作微调，还可以在拍柄的中空结构中，和或在拍面不 同的填充腔内，填充不同密度的发泡胶来实现。
11、在本设置方式注塑一体成型的板式球拍，所述拍面部与所述的拍柄部之间通过至少一根拍杆连接。

具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，对本发明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发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，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，都属于本发明保护的范围。
为了更好的理解上述技术方案，下面将结合说明书附图以及具体的实施方式对上述技术方案进行详细的说明。
实施例1：
如图1-图15所示，一种注塑一体成型的板式球拍，包括拍面部1和拍柄部2，拍面部1内设有多个独立的填充腔6，填充腔6的一端封闭，另一端开放，开放端有一封条组件9将其封闭，拍柄部2有一个独立的中空结构7，中空结构7一端封闭，另一端开放，中空结构7的开放端远离拍面部1，中空结构7的开放端的端口有一盖子3将其封闭。
在本实施例中，盖子3和拍柄部2的中空结构7开放端开口可采用粘剂、插接、过盈结构或卡扣方式。
当盖子3采用插接方式时，具体的盖子3上设有插接块，插接块过盈插接到发泡材料注入的中空结构7中，盖子3便可封闭中空结构7的开放端的端口。
在本实施例中，所述拍柄部2的中空结构7中注入发泡胶填充其中。
在本实施例中，拍面部1内通过若干支撑筋5形成相互独立的填充腔6，相互独立的填充腔6互不相通，支撑筋5有三种设置方式：第 一种是垂直于拍柄部2方向设置在可填充腔内，如图2所示，第二种是平行于拍柄部2方向设置在可填充腔内，如图3所示。
其中，横向设置(垂直于拍柄部2)的支撑筋5，更适合横拍式乒乓球拍。竖向设置(平行于拍柄部2)的支撑筋5，更适用于直拍式乒乓球拍，如此设置的原因主要是考虑直拍和横拍用拍习惯不同，其与拍把反向的端面接触桌面机会增加，在拍面受到桌面冲击时，多条支撑筋5会支撑拍面部1。
本实施例中，注塑一体成型的板式球拍可为乒乓球拍、海滩拍或板式网球拍等注塑一体成型的板式球拍。
在本实施例中，所述拍面部1内相互独立的填充腔6内，注入发泡胶填充其中。
在本实施例中，拍柄部2的表面进行二次注塑成型，表面形成一软质高分子薄层。
在本实施例中，所述拍柄部2的表面所形成的软质高分子薄层的材质为TPR和或TPE。
在本实施例中，在拍面部1的肩部，即手指拿捏位置的表面二次注塑成型，即在肩部处表面形成一软质高分子薄层，软质高分子薄层的材质为TPR和或TPE。
在本实施例中，拍面部1表面原本设置胶皮的胶皮设置区域也二次注塑，形成软质塑料层，以代替胶皮，软质塑料层可采用TPR、TPE、PVC(或其它材质)等软质层。
在本实施例中，第三种是在第一种基础上加上一根竖向主轴筋4，具体如图8所示，第三种相较于第一种结构强度更高，且拍面部1和拍柄部2通过注塑一体成型，拍面部1内部的主轴筋4沿球拍中心轴线将拍面部1内部均匀地一分为二，因为主轴筋4沿球拍中心轴线设置，引起主轴筋4的两侧以球拍中心轴线为中心线对称，所述拍面部1内部多个独立的填充腔通过主轴筋4和若干支撑筋5分隔而成，若干支撑筋5沿球拍中心轴延伸方向间距排列，且支撑筋5的两端以球拍 中心轴为中心线对称设置，支撑筋5的两端分别延伸至拍面部1的侧壁上，继而支撑筋5的两端沿主轴筋4呈轴对称设置。
在本实施例中，位于主轴筋4不同段落上的支撑筋5密度可以根据球拍的重心位置要求进行设定，如图8所示，以实现球拍重心是靠近拍柄部2还是远离拍柄部2，以适应选手不同的使用习惯。
在本实施例中，主轴筋4各段落的粗细也可根据重心位置要求进行设定，如图9和图10所示，以实现球拍重心是靠近拍柄部2还是远离拍柄部2，以适应选手不同的使用习惯。如图9由远离拍柄部2的一端到靠近拍柄部2的一端的粗度逐渐增大。如图10所示由靠近拍柄部2的一端到远离拍柄部2的一端的粗度逐渐增大。
在本实施例中，位于主轴筋4不同段落上的拍面部1的拍面壁厚根据重心位置要求进行设定，实现球拍重心是靠近拍柄部2还是远离拍柄部2，以适应选手不同的使用习惯。
在本实施例中，如图11-图12所示，用于封闭填充腔6开口8的是一封条组件9，该封条组件9是一次注塑成型的保护带11，该保护带11的外侧面为平整面，保护带11的内侧面设有若干凸块10，凸块10的位置和尺寸正好与填空腔6的开口8的位置和尺寸吻合，当封条组件9上的各个凸块10分别被嵌入各自对应的填充腔6的开口8后，保护带11外侧面正好贴合在拍面部1的周边。
在本实施例中，拍面部1的拍面依次设有海绵层和胶皮层。
在本实施例中，封条组件9的保护带11的边沿超出拍面部1的边沿，并且与拍面部1拍面上的胶皮层表面齐平，以使拍面部1的海绵层及胶皮层的侧面也受到保护带11的保护。
在使用的过程中，打开保护带11即可向拍面部1的填充腔6内注入发泡材料，注入完后封闭保护带11即可，发泡材料能够增加拍面部1的厚实感，部分吸收球拍击球时产生的震动，从而提高拍面的击球弹性，避免震动消耗拍面击打球体的动能，降低球体飞行距离和精度。本注塑一体成型的板式球拍中的拍面部1和拍柄部2由注塑工艺一次 注塑而成，因此不会出现木制球拍遇水易变形的问题以及板面出现分层的问题。本申请中拍面部1和拍柄部2为中空设置，能够显著降低注塑一体成型的板式球拍整体重量，解决了传统球拍较重的问题。
