[0002] With the rapid development of the automobile industry, different models with high and low configurations have emerged for each brand of automobile. In order to save the development cost of molds, more and more automobile manufacturers require the use of switching mechanisms during the mold development stage, that is, a set of molds can produce two types of parts through the switching of the switching mechanism. For example, in the common cases of the roof with or without a sunroof, and whether the rear door has a spoiler.

[0003] Usually, the driving of the mold switching mechanism is completed by a cylinder, and the switching mechanism is usually placed in the upper mold. At present, whether the upper mold slider of domestic machine tools has a gas source is not consistent, and the upper mold gas source is not necessarily stable. Even for the upper mold sliders with a gas source, many automobile manufacturers do not prefer to connect the upper mold gas source.

[0004] In order to ensure the stability of the two states of the switching mechanism, a self-locking device is usually set in the mold. At present, the commonly used self-locking form in the mold is the bead type, but this method is not stable, and the switching mechanism may accidentally fall off during the stamping process, resulting in the omission of some working contents of the stamping parts, wasting time in troubleshooting and rectification, and affecting production efficiency.
