Abstract
A molding apparatus and method of use thereof. The molding apparatus has a stationary mold base, and at least one moveable mold core rotatable into and out of a facing relationship with the stationary mold base. When the moveable mold core is in its closed position, it cooperates with the stationary mold base to define a mold cavity. The mold base may be shaped so as to aid in forming a part, or to hold a sheet of material onto which molding material is to be deposited so as to encapsulate the part on one or more edges or surface regions. Structure may also be encapsulated onto the surface of the material during the molding operation.
Claims24
An apparatus for encapsulating a sheet of glass including:
- a) a frame member,
- b) a stationary mold base mounted to said frame member and having at least a portion of a mold cavity therein,
- c) a movable top mold core having at least a portion of a mold cavity formed therein, and rotatable about a fixed pivot point between a closed position in a facing relationship with said stationary mold base, and an open position rotated away from said mold base, said portion of said mold cavity in said movable top mold core being adjacent said portion of said mold cavity in said stationary mold base when said movable top mold core is in its closed position,
- d) a movable side mold core having at least a portion of a mold cavity formed therein and moveable between a closed position in a facing relationship with said stationary mold base, and an open position rotated away from said mold base, said portion of said mold cavity in said movable side mold core being adjacent said portion of said mold cavity in both said mold base and said moveable top mold core when said movable side mold core is in its closed position, and at least a portion of said sheet of glass to be encapsulated being contained in the mold cavity formed by said stationary mold base, said moveable top mold core, and said moveable side mold core,
- e) means to rotate said movable top mold core between its open and its closed position,
- f) means to rotate said movable side mold core between its open and its closed position,
- g) means to introduce molding material into the mold cavity formed when said movable mold core is in its closed position, and
- h) control means to control said means to rotate and said means to introduce.
An apparatus for encapsulating a sheet of glass including:
- a) a frame member,
- b) a multi-part mold base mounted to said frame member,
- c) a moveable top mold core having a portion of a mold cavity formed therein and moveable between a closed position in a facing relationship with said multi-part mold base, and an open position rotated away from said mold base, said portion of said mold cavity in said top moveable mold core being adjacent said multi-part mold base when said at least one moveable mold core is in its closed position, and at least a portion of said sheet of glass to be encapsulated being between said stationary mold base and said moveable mold base, and forming a part of said mold cavity,
- d) a moveable side mold core having a portion of a mold cavity formed therein and moveable between a closed position in a facing relationship with said multi-part mold base, and an open position rotated away from said mold base, said portion of said mold cavity in said side moveable mold core being adjacent said multi-part mold base and the portion of said mold cavity formed in said moveable top mold core when said moveable side mold core is in its closed position, and at least a portion of said sheet of glass to be encapsulated being between said stationary mold base and said moveable mold base, and forming a part of said mold cavity,
- e) means to rotate said moveable top mold core between its open and its closed position,
- f) means to rotate said moveable side mold core between its open and its closed position,
- g) means to introduce molding material into the mold cavity formed when said moveable top and side mold cores are in their closed position, and
- h) control means to control said means to rotate and said means to introduce.
