Safety

Post by DBWhirldge » Fri Nov 02, 2018 3:46 pm

We just did an in house safety audit of our plastics department.
The main thing they found was the setup men were connecting water hoses to the bottom of a mold while it was suspended by the overhead crane. The mold was high enough that hey could get under the mold to see what they were doing. We have done this for years and never had a problem. Our safety committee would like for us to find a way to attach the hoses without needing to be under a suspended load.

We are thinking of building a stand to support the mold that will allow access to the bottom of the mold.
Does any body have an idea or a better solution?

We began to recess the quick connects on the bottom of our molds so the quick connector couple was at least a 1/16" below the bottom surface of the mold.
We could leave the quick connects in the mold and still set the tool down on the floor or in racking.

I never like to stand under a suspended load! Plumb the mold to a common manifold on the side or top of the mold. Allows for faster mold changes and also maintains water line conformity from run to run.

We do the same, and in addition, we have a set of mold stands (think saw horses capable of carrying 6T) in the mold shop to facilitate installation and removal of the water pipes that are to the bottom of the mold. The mold stands are on spring-loaded casters so they're easily moved into position but feet are engaged to the floor when the stand is under load.

Bruce,

We complete the installation of the mold before attaching the water lines. Both halves of the mold are clamped to the platens and the mold is opened and closed to make sure the tool is secure. The mold is then closed before the water lines are connected. By doing this while the mold is closed it insures that the water lines are clear of each other when the mold is closed. It is still necessary to be under the mold but only when it is securely clamped to the press.
