Patent ID: 8182260

Claim:
A mold for forming a molded product having at least one tapered wall, said mold comprising: a frame; and at least one mold cavity, said at least one mold cavity having a plurality of cavity walls defining the sides of said mold cavity, and said at least one mold cavity having an open top through which moldable material can be introduced into said mold cavity; wherein at least one of the plurality of cavity walls is a movable wall, the movable wall comprising: a stationary element attached to said frame, said stationary element having a groove; a pivot element having first and second pivot points horizontally disposed with respect to one another only along a substantially straight horizontal line extending therebetween, which is parallel to a main surface of a pallet and perpendicular to a vertical sectional plane of the mold when the mold is in a closed position, said pivot element being rotatably attached to said stationary element via said first pivot point; and a movable element having a planar product forming surface, said movable element being slidably and rotatably attached to the groove of said stationary element and said movable element being rotatably attached to said pivot element via said second pivot point, such that said movable element is capable of moving between a first position and a second position, wherein said first pivot point is directly connected to said stationary element, wherein said mold moves toward the pallet such that the pallet directly contacts and engages said movable element and forces said movable element from the first position to the second position, and wherein said mold permits demolding of the molded product when said mold moves vertically away from said pallet, and the vertical and horizontal movement of the movable element from the second position into the first position is delayed due to the slidable and rotatable connections of the movable element.
