3. Detachable design
During the use of the mold, some parts are subject to excessive friction and impact, and the wear is large. At this time, only the parts need to be replaced, and the mold can still be used.
In addition, sometimes a new product can be produced by simply changing the working parts. Non-removable not only causes waste of a large number of reusable parts, but also seriously pollutes the environment due to poor disposal of waste.
Therefore, the problem of disassembly must be considered at the beginning of the design.
(1) Select the general structure as much as possible for replacement.
(2) Under the premise of meeting the strength requirements, try to use detachable joints, such as threaded joints, without welding, riveting, etc.
