The guide post and guide sleeve unit of the mold?

There are two types of mold guide methods and accessories: guide posts and guide sleeve units: (A). Outer guide type (mold base type or main guide), (B). Inner guide type (or auxiliary) lead). In addition to meet the requirements of precision molds, there is a high demand for the use of both external and internal guidance.
(1) External guide type: Generally used for molds that do not require high precision, most of them are sold as a unit with the mold base. The main function is that the blades are aligned when the mold is installed on the punching machine. There is almost no stamping process. Dynamic accuracy retention effect.
(2) Inner-guided type: Due to the development of mold processing machines, it is rapidly popularized. The main function is not only the alignment of the blades when the mold is installed on the punching machine, but also the dynamic accuracy maintenance effect in the stamping process.
(3) External guidance and internal guidance combined use type: a pair of molds simultaneously use external guidance and internal guidance devices.
