Preforms transporting system
In the exit of the heating oven, the heated preforms will be picked by the star wheels.
Then, the heated preforms will be clipped by a mechanical clip (smaller cylinder with jaw normally), and then be transported to the mold.
The preforms clips should be cleaned regularly.
The mechanical clip should be checked regularly to see of any of them are damaged or deformed.
Molds opening & closing system
1. Opening & closing arm. It is used for opening and closing the mold rack to open an close the two parts of the molds.
Check regularly to see of the arm is not fixed tight.
Lubricate the necessary connection part, and make good protection. Lubricant oil or butter are fine.
2. Cam guide. There are two sets of cam sticks which are used for lock or unlock the mold rack. A big cylinder is used there to set up the suitable location of the mold rack and then open and closet the mold rack.
The rotary axis should be lubricated regularly .
The drive bearings should be lubricated regularly.
Check the buffer device for the opening and closing device.
Check all connections and joints to make sure they are fixed tightly.
3. When the mold is closed and locked, there will be around 0.25-0.35mm gaps between the two parts of the mold. The blowing process will close that gap by the blowing pressure by a compensation way. Then, the pressure will be the same in both internal and external parts.
all necessary parts should be lubricated, such as the mold, the mold rack, the transporting stick, the buffer device, the guide rail etc.
