If a cylinder ejector must be used, incorporate a proximity safety switch and use non-ferrous materials where it enters the die, or it must be of positive return design.
如果必须使用汽缸，使用一个移接近的安全开关，并在其进入模具的部分使用不含铁的材料，或者在设计上它能合理的返回。
The jacking work bar of the ejector can return by itself with convenience to feed next blank hence the assistant time decreased and work efficiency improved.
模具采用自动返回顶料器，减少了辅助时间，提高了工作效率。
