在本实施例中，第五连杆 19 的另一端通过第七轴 21 铰接在第二摆臂 18 的另一端上，第六连杆 20 的另一端也通过第七轴 21 铰接在第二摆臂 18 的另一端上。第五连杆 19 的一端通过第八轴 22 铰接在第一模架 3 上，第六连杆 20 的一端通过第九轴 23 铰接在第二模架 4 上，第八轴 22 和第九轴 23 呈轴对称分布的中心线经过第一轴 2 。第七轴 21 、第八轴 22 、第九轴 23 均沿竖直方向分布。
通过第二轴 6 绕自身轴心线方向的转动，带动第二摆臂 18 跟随第二轴 6 转动。第二摆臂 18 的一端固定的套设于第二轴 6 上。
第二摆臂 18 的另一端转动远离第一轴 2 时（即第二轴 6 顺时针转动时），通过第五连杆 19 和第六连杆 20 带动第一模架 3 和第二模架 4 转动开模。
第二摆臂 18 的另一端转动靠近第一轴 2 时（即第二轴 6 逆时针转动时），通过第五连杆 19 和第六连杆 20 带动第一模架 3 和第二模架 4 转动合模。
以下具体阐述下本实施例的工作过程：
合模时：
第一摆臂 7 沿靠近底模模架 5 的方向转动，通过连杆机构带动第五轴 12 沿靠近底模模架 5 的方向运动，使角度 a 增大，此时底模模架 5 上升；
此时，第二摆臂 18 的另一端转动靠近第一轴 2 （即第二轴 6 逆时针转动），通过第五连杆 19 和第六连杆 20 带动第一模架 3 和第二模架 4 转动合模。
开模时：
第一摆臂 7 沿远离底模模架 5 的方向转动，通过连杆机构带动第五轴 12 沿远离底模模架 5 的方向运动，使角度 a 减小，此时底模模架 5 下降；
此时，第二摆臂 18 的另一端转动远离第一轴 2 （即第二轴 6 顺时针转动），通过第五连杆 19 和第六连杆 20 带动第一模架 3 和第二模架 4 转动开模。
上述实施例只为说明本发明的技术构思及特点，其目的在于让熟悉此项技术的人士能够了解本发明的内容并据以实施，并不能以此限制本发明的保护范围。凡根据本发明精神实质所作的等效变化或修饰，都应涵盖在本发明的保护范围之内。
