模具被称为“制造业之母”，是制造业中的重要器具，在模具的使用过程中往往需要对模具进行移动，如开合模等，一般都采用液压系统来完成。液压系统的优点是输出力大，但其缺点也很明显，如需要解决液压不足的问题、漏油导致生产环境清洁度不够等。为了解决液压不足的问题，液压系统依赖于油泵的及时补油，现有技术中，例如一种在中国专利文献上公开的“一种液压系统及模具”，其公开号为CN106194867A，同时设置了第一油泵和第二油泵，且第一油泵和第二油泵可同时工作，因此，可以为第一油缸组和第二油缸组提供充足的压力油，使得液压系统工作的可靠性更好。但其缺点是增加了结构的复杂度，且并没有解决生产环境清洁度不够的问题。
除了上述方法外，现有技术中也有通过驱动电机与丝杆进行驱动模具，但是此种方式驱动力小，无法适应一些大型产品的生产工况。

具体实施方式
为使本发明实现的技术手段、创作特征、达成目的与功效易于明白了解，下面结合附图和具体实施方式，进一步阐述本发明是如何实施的。
实施例一，如图1-5所示，一种油电混合开合模具，包括模具与驱动机构，模具包括与传动杆直接连接的下模和与传动杆滑动连接的上模5，且上模5位于下模6和液压缸1之间，驱动机构包括：
液压缸1，液压缸1与模具相连且设置四个，并能够带动模具开合；
丝杆2，丝杆2与液压缸1的活塞杆11螺纹连接，数量与液压缸1对应；

驱动电机3，用于将动力传递给同步带4。
液压缸1包括：
活塞17；
补油通道12，联通活塞17两侧，补油通道12内设置有能够开闭补油通道12的补油阀13。液压缸1的活塞17做功时，可通过补油通道12进行补油，无需外接油泵，简化了结构的同时进一步减少了油液污染；
传动杆15，位于活塞17背向活塞杆11的一侧，内设有空腔且空腔内设置有用于操纵补油阀13移动的阀杆16，阀杆16从传动杆15空腔内穿出，因此能够在传动杆15外控制补油阀13的移动；
输油口14，活塞将液压缸1分为两个腔体，两个腔体均设置有输油口14，输油口14均与外设的油泵相连，通过油泵输出压力油以及补油，使得液压缸1提供更大的驱动力，从而在电机控制的情况下大大提高整体的输出驱动力。
进一步的，补油通道12靠近模具的一侧设置有能容纳补油阀13进出的补油腔121，补油阀13进入补油腔121时补油通道12被打开，补油阀13结构简单，方便制造。
进一步的，补油阀13为哑铃形，两端能够封住补油通道12，补油通道12至少设置两次拐弯，补油阀13中间较细的部分的长度大于补油通道12两次拐弯处之间的距离。此种补油阀13形状使得补油阀13外表与补油通道12的内壁形成过油通道，过油速度更加稳定。
进一步的，阀杆16与补油阀13螺纹连接，补油阀13与补油通道12的横截面为方形，补油阀13无法在补油通道12内转动，阀杆16穿出传动杆15的一端设置有传动齿轮和用于驱动传动齿轮的电机7，通过电机7驱动阀杆16旋转，从而带动补油阀13平移，从而达到 开闭补油通道12的目的。
实施例一的工作原理是，驱动电机3驱动同步带4，同步带4带动多个丝杆2同步转动从而驱动活塞杆11提供开合模的一部分动力，同时，液压缸1通过输油口14补充油泵带来的压力油提供另一部分驱动力，因此能够提高单一液压缸1的驱动力的同时，驱动电机3与丝杆2的结构不污染工作环境，且由于驱动电机3的特性，整个模具的开合过程相比纯液压缸1控制更加精准及时。
实施例二，阀杆16穿出传动杆15的一端连接有气动杆，通过启动杆拉动阀杆16，从而带动补油阀13平移，从而达到开闭补油通道12的目的。其他结构与实施例一相同。
实施例三，阀杆16穿出传动杆15的一端连接有电磁开关，阀杆16靠近电磁开关一侧设置有磁性，通过电磁开闭吸引阀杆16移动，从而带动补油阀13平移，从而达到开闭补油通道12的目的。其他结构与实施例一相同。
实施例四，液压泵上不设置输油口14，其他与实施例一相同，本实施例中的液压泵能够通过补油通道12进行补油，因此省去了油泵设备，液压泵作为驱动力的放大设备，驱动电就作为控制和驱动设备，使得本实施例结构简单，油液污染小，开合模控制精准及时。
实施例五，一种注塑机构，包括实施例一的一种油电混合开合模具，如图1和图5所示，还包括注塑设备8，由于油电混合开合模具输出力大，省去了动力放大结构，使得注塑机整体的结构更加精简，使得注塑设备的位置安排更加灵活。
