Mold Module Design(2)

2. Guide post and guide sleeve unit

There are two types of guide posts and guide sleeve units for the guide methods and accessories of the mold:
(A). Outer guide type (mold seat type or main guide),
(B). Inner guide type (or auxiliary guide) lead). In addition to the requirements of precision molds, there is a high demand for the use of external guides and internal guides.
(1) External guide type: generally used for molds that do not require high precision, and most of them are sold as a unit with the mold base. The main function is to match the blade parts when the mold is installed on the punch, and there is almost no stamping process. Dynamic precision maintains the effect.
(2) Internal guide type: Due to the development of mold processing machines, it is rapidly popularized. The main function is not only the abutment of the blades when the die is installed on the punching machine, but also the dynamic precision maintenance effect in the punching process.
(3) Combined use of external guide and internal guide: a pair of molds use external guide and internal guide at the same time.

3. Punch and die unit (round)

(1) Punch unit: According to its shape (shoulder type and straight type), length and convenience of maintenance, the circular punch unit should be used with the pressing plate guide sleeve unit.
(2) Die unit: The circular die unit is also called the die guide sleeve unit, and its forms are monolithic and separate. According to the production quantity, service life and rationality of products or chips, the The combination series are:
(A). Use the template to directly process the shape of the die,
(B). The escape part with two bevels,
(C). Whether to use the back plate,
(D). The shape of the irregular die must be There is a rotation prevention design.
