 本发明的实施方式
以下是本发明的具体实施例并结合附图，对本发明的技术方案作进一步的描述，但本发明并不限于这些实施例。
如图1-4所示，一种侧冲顶废料模具结构，包括从上到下依次设置的上模座1、上垫板2、固定板3和下模座4，模座4上方设有垫板10，上模座1的下方设有竖直设置的第一驱动冲头5，其与垫板10上设置的滑块驱动块12相配合，通过第一驱动冲头5驱动滑块驱动块12水平移动，带动与滑块驱动块12连接的滑块11水平移动，进而带动滑块11上安装的顶杆冲头13水平移动，顶杆冲头13穿设于侧冲冲头17内，在滑块11的带动下穿过侧冲冲头17，实现对刀口19上冲裁的产品22的废料的顶出；上垫板2的下方设有竖直设置的侧冲驱动冲头6、第二驱动冲头7和第三驱动冲头8，垫板10上滑动设有侧冲滑块15、侧冲滑块驱动块16、侧冲脱料板18和挡块20，其中，侧冲驱动冲头6与侧冲滑块驱动块16相配合，第二驱动冲头7与侧冲脱料板18相配合，第三驱动冲头8与挡块20相配合，通过上垫板2驱动第二驱动冲头7和第三驱动冲头8下行，使得侧冲脱料板18和挡块20相向移动，侧冲脱料板18和挡块20同时向刀口19的位置移动，夹住刀口19上的待加工的产品22的两侧，侧冲驱动冲头6驱动侧冲滑块驱动块16向刀口19的位置移动，带动侧冲滑块15同步移动，进而带动侧冲滑块15上安装的侧冲冲头17向刀口19的位置移动，实现对刀口19上的待加工的产品22的侧冲；垫板10上方设有滑块座，滑块11、滑块驱动块12、侧冲滑块15、侧冲滑块驱动块16、侧冲脱料板18和挡块20均滑动设置于垫板10上方的滑块座内，保证滑块11、滑块驱动块12、侧冲滑块15、侧冲滑块驱动块16、侧冲脱料板18和挡块20能够实现水平移动。
本申请中，滑块驱动块12的靠近第一驱动冲头5的侧边设有V形斜面，第一驱动冲头5的下端设有与滑块驱动块12的V形斜面相配合的V形斜面。当冲床带动模具向下运动进行合模时，第一驱动冲头5向下运动，第一驱动冲头5的下端V形斜面不接触滑块驱动块12上的V形斜面，滑块驱动块12保持不动，进而不会驱动滑块11及其上设置的顶杆冲头13发生水平移动，因此合模时顶杆冲头13保持不运动；当冲床带动模具向上运动进行开模时，上模座1驱动第一驱动冲头5移动到设定位置时，第一驱动冲头5上的V形斜面与滑块驱动块12上的V形斜面贴合，推动滑块驱动块12向刀口19的位置方向移动，带动滑块11上安装的顶杆冲头13向着刀口19的位置移动，使得顶杆冲头13能够从侧冲冲头17内穿出，实现顶出刀口3上产品22冲裁产生的废料；同时，第一驱动冲头5与上模座1连接，其为单独驱动结构，能够达到一种刚性脱料的目的，能有效的改善因废料落料不顺而导致的堵料的问题，能够加强刀口19的结构强度，更好的进行侧冲作业。
本申请中，侧冲驱动冲头6下端的斜面与侧冲滑块驱动块16上端的斜面相配合，实现侧冲驱动冲头6驱动侧冲滑块驱动块16水平移动，实现驱动侧冲冲头17刺入待冲裁的产品22上，完成侧冲；第二驱动冲头7下端的斜面与侧冲脱料板18上端的斜面相配合，第三驱动冲头8下端的斜面与挡块20上端的斜面相配合，通过第二驱动冲头7和第三驱动冲头8实现驱动侧冲脱料板18和挡块20同步相向移动，实现对刀口19上的待加工的产品22的夹持固定；同时，挡块20能够顶住待加工的产品22，可抵消侧冲冲头17侧冲时产生的侧冲力，增加侧冲的稳定性，提高产品22的加工质量。
本申请中，垫板10上设有第一靠块14，第一靠块14设置于滑块11和侧冲滑块驱动块16之间；滑块11与第一靠块14、侧冲滑块驱动块16与第一靠块14之间均设有用于复位的氮气弹簧；侧冲脱料板18与侧冲滑块15之间活动连接有拉杆，侧冲冲头17穿设于侧冲脱料板18内。通过第一靠块14的设置，便于用于复位的氮气弹簧的固定，进而能够实现开模后滑块11和侧冲滑块15的复位；而侧冲滑块15与侧冲脱料板18之间连接的拉杆，在侧冲滑块15复位的同时，能够拉动侧冲脱料板18同步移动，实现侧冲脱料板18的复位。而侧冲冲头17穿过侧冲脱料板18，可实现对待加工的产品22的侧冲。
本申请中，挡块20的远离刀口19的一侧设有第二靠块21，第二靠块21设置于垫板10上，挡块20与第二靠块21之间设有用于复位的氮气弹簧，第二靠块21用于氮气弹簧的安装固定，实现挡块20在开模后的复位。
本申请中，固定板3的下方设有压料块9，压料块9设置于刀口19的正上方且与刀口19相配合，通过压料块9的设置，实现对待加工的产品22的顶部的压紧，保证待加工的产品22的在合模时固定牢固。
本申请中，该侧冲顶废料模具结构的工作流程为：1）待加工的产品22通过送料机和定位针送入到刀口19处。
2）合模时，通过固定于上固定板3上的压料块9对待加工的产品22的顶部进行压紧。
3）压力机驱动上垫板2下行，第二驱动冲头7和第三驱动冲头8随着上垫板2的下行，分别同步驱动侧冲脱料板18和挡块20相向移动并压紧待加工的产品22的两侧。
4）侧冲驱动冲头6在上垫板2的作用下下行，驱动侧冲滑块驱动块16向着刀口19的位置方向移动，带动侧冲滑块15同步移动，进而带动侧冲冲头17在侧冲脱料板18内运动，刺入待加工的产品22内，完成侧冲。
5）开模时，上垫板2带动侧冲驱动冲头6、第二驱动冲头7和第三驱动冲头8上行，侧冲滑块驱动块16在氮气弹簧的作用下先行复位，带动侧冲滑块15及侧冲冲头17复位，进而实现脱料。
6）挡块20在氮气弹簧的作用下复位，同时侧冲脱料板18在侧冲滑块15的作用下同步移动复位，实现释放产品22。
7）第一驱动冲头5在上模座1的作用下上行，第一驱动冲头5上的V形斜面与滑块驱动块12上的V形斜面贴合，带动滑块驱动块12水平向着刀口19的方向移动，带动滑块11水平移动，实现带动顶杆冲头13在侧冲冲头17内移动，穿过侧冲冲头17，顶出刀口19上产品22冲裁后产生的废料。
8）当产品22被取出后，进行下一次冲裁合模，随着上模座1的下行，第一驱动冲头5随着上模座1下行，第一驱动冲头5上的V形斜面下行与滑块驱动块12上的V形斜面分离，滑块驱动块12在氮气弹簧的作用下水平向着远离刀口19的方向移动，实现滑块驱动块12的复位，带着滑块11及顶杆冲头13复位，从而使顶杆冲头13退回侧冲冲头17内，远离刀口19，进行下一次冲裁。
