回程位置

In the top drawing the ejector pin is in the rear position, and it is held back by push-back pins.

夹持回程皮带带芯钢丝绳，位置尽量靠近需要更换的滚筒。注意：对于爬坡或下坡皮带来说，您可使用多个皮带夹，可牢靠夹持皮带防止夹持不牢靠遭成打滑。将皮带夹进行牢靠锚接固定，也可直接将其直接固定到输送机支架的坚固部件上或其它可靠的锚接锁链上。具体参考输送机设计图纸。

Thus, when the mould is in the process of being closed, the push-back pins strike the fixed mould plate and progressively return the ejector plate assembly to the rear position.

因此，当模具闭合的时候，回程杆撞击定模板，逐渐地把顶料板组合退回到后面的位置。

When a mould is fitted to a machine which incorporates a hydraulic actuating system, providing the ejector rod is positively coupled to the hydraulic ram, the return of the ejector plate assembly follows automatically.

可是，甚至于在这种情况下，许多设计者仍喜欢装一个回程杆系统，作为一个安全部件，以确保顶料系统完全回复到早先注射阶段的位置。
