Plate
transfer process occurs during the machining and assembly of mold, both
for the cavity and mold base plate, especially for the plate with a
weight greater than 20 kg, threaded hole necessary to facilitate the
transfer process. cause may be in a mold plate having a various of
machining processes with different types of machines. Base on position
of hole the type of lifting bolts can divided became two, perpendicular
to face, and parallel with face of plate.
perpendicular to face
beside
transfer process, lifting bolts also important for lift out cavity
insert from mold base, flat wide plate usually use magnet to lift from
one machine to another machine or station, but if shape of plate doesn’t
flat it need bolts hole to attach eye bolts, then use crane that
connected to eye bolts for lifting the mold base plate or cavity plate.
Parallel with mold face.
Especially
for mold base, this hole must available because transfer mold base
usually use eye bolt that connected to crane, for mold base plate that
use horizontal machining also use this hole to connected with crane,
picture below shown mold base with metric bolt hole and eye bolts ready
for transfer with crane
