Abstract:
1. A method of forming a molded product having at least one tapered wall, said method comprising the steps of: moving a mold assembly towards a pallet, the mold assembly comprising: continuing to move said mold assembly toward said pallet to engage the pallet with each movable wall so that the pallet forces each movable wall from said open position to said closed position while rotating and sliding each first attachment point upwardly along its respective slot or channel and while rotating each pivot element end about its respective second attachment point and pivot point; introducing a quantity of moldable material through each open mold cavity top and into each mold cavity while each movable wall remains in the closed position; allowing the introduced moldable material to remain in each mold cavity while each movable wall remains in the closed position and until the introduced moldable material forms a self-sustaining molded product; and moving the mold assembly away from the pallet and self-sustaining molded product so that the self-sustaining molded product remains on the pallet and so that each movable wall moves from the closed position back to the open position while rotating and sliding each first attachment point downwardly along its respective slot or channel and while rotating each pivot element end about its respective second attachment point and pivot point.
