为实现上述目的，本实用新型提供一种双导向的吹瓶机开合模机构，包括模架，所述模架的底部设有相对于所述模架前后滑动的滑架，所述模架内部设有可横向滑动的侧模座，所述模架与所述侧模座之间设有升降的锁模板，所述滑架上加工有多个曲线槽，所述侧模座及所述锁模板具有与所述曲线槽对应的滚轮，所述滑架通过所述曲线槽间接带动所述侧模座及所述锁模板运动，所述侧模座与所述模架之间设有第一滑动机构，所述第一滑动机构为滑块导轨式结构，所述侧模座与所述锁模板之间设有第二滑动机构，所述第二滑动机构包括固定在所述锁模板上的第一导向块、固定在所述侧模座上的第二导向块，所述第一导向块上加工滑道，所述第二导向块具有伸入所述滑道的凸部；
该吹瓶机开合模机构设置了两套滑动机构，改变了现有的侧模座仅仅在底部设置导向的惯有设计方式，使得侧模座的移动更加稳定，合模精度提高。
优选地，所述模架下方设有丝杆滑块组件，由所述丝杆滑块组件驱动所述滑架相对于所述模架做前后滑动；
在上述技术方案中，滑块是与滑架固定连接的，丝杆的驱动源可以选择步进电机或者伺服电机，使得控制精度得到保证。
优选地，所述第一导向块、所述第二导向块各设有三组并在高度方向上等间距分布；
在上述技术方案中，第一导向块、第二导向块的多组设计，有效保证了一定高度的侧模座的稳定性。
