In C font opening；
The powder case locking cylinder of each powder case automatic locking mechanism acts, and pushes along powder case locking pin 651 and locking guide post
656 respectively axial movements, and then the fixed otic placode of powder case in C font opening is passed through by powder case locking pin 651, realize consolidating for powder case
It is fixed；
Mold is delivered to the surface of resupination framework by manipulator, and drops to the mold mounting side mouth word of resupination framework
On type working face, quick guide-localization is carried out using mold guide holder during decline；After mold is placed on resupination framework,
The piston rod of mold-locked cylinder stretches out, and pushes rotating arm to rotate around the first pin shaft, due in the upper end and rotating arm of safe closing piece
Portion is hinged by the 4th pin shaft, thus also drives safe closing piece mobile, using the limiting section in the middle part of safe closing piece downwardly against lock
The locking head of latch segment is then pressed to the side edge of mold so that latch segment is rotated around the second pin shaft by tight block, so that mold
Locking.
After slush moulding bed is started to work, mold and hopper carry out rotary movement under the drive of resupination framework, and mold is turning
Have the tendency that being detached from resupination framework during dynamic, give one power reversed with compaction direction of compact heap, which is making
When on compact heap, so that compact heap is rotated up around the second pin shaft, then to safe closing piece and hinged with safe closing piece
Rotating arm upper end apply upward power, and since the lower end of rotating arm and rotation arm seat are hinged, and the first pin shaft, third pin
The axis of axis and the 4th pin shaft is generally aligned in the same plane in A, so that safe closing piece is applied to the power of rotating arm and rotation arm seat is held
The power of rotating arm is completely counterbalanced by, and eliminates the trend of mould separating resupination framework, plays the effect of safe locking, it is ensured that mold is not
Resupination framework can be detached from.
In resupination framework switching process, the TPU plastic powders in powder case are introduced into the mold after heating, and amount of powder is just
It is uniformly melted on the surface for the slush mold inner cavity being heated, forms instrument board slush moulding epidermis in mold inner-cavity, then
Resupination framework stops operating, so that mold mounting side is upward, powder installs side downward, by Qiao Fen mechanism by unfused powder
It strikes from mould inner wall, completes slush moulding.
