Devices and methods for dynamic pixel molding
View Patent ↗Systems and methods for reusable molding devices in accordance with embodiments of the invention are disclosed. In one embodiment, a reusable molding device is provided comprising: an array comprising a plurality of pixel pins, which are arranged to form a two-dimensional plane and which are each linearly movable to create an impression of a surface of an object, a first pixel guide plate, a second pixel guide plate, a first clamp pressure plate, a second clamp pressure plate, a first clamp screw, wherein the first clamp screw moves the first clamp pressure plate towards the first side of the array, a second clamp screw which moves the second clamp pressure plate towards the second side of the array, a pressure clamp frame enclosing the first and second pixel guide plates and the first and second clamp pressure plates, and a top pressure plate, which includes an injection entrance bore.
1. A reusable molding device for producing three-dimensional (3D) molds, the reusable molding device comprising:
an array comprising a plurality of pixel pins, and wherein each one of the plurality of pixel pins is linearly movable to create an impression of a surface of an object;
a first pixel guide plate connected to the array, wherein the first pixel guide plate provides support to a first side of the array; and
a first clamp pressure plate configured to apply pressure to the array, wherein the first clamp pressure plate is located opposite to the first pixel guide plate;
a second pixel guide plate connected to the array, wherein the second pixel guide plate supports a second side of the array;
a second clamp pressure plate configured to apply pressure to the array, wherein the second clamp pressure plate is opposite the second pixel guide plate; and
a pressure clamp frame enclosing the first and second pixel guide plates and the first and second clamp pressure plates.
2. The reusable molding device of claim 1 further comprising a first clamp screw connected to the first clamp pressure plate, wherein the first clamp screw moves the first clamp pressure plate towards the first side of the array and moves away from the first side of the array.
3. The reusable molding device of claim 1 further comprising a second clamp screw connected to the second clamp pressure plate, wherein the second clamp screw moves the second clamp pressure plate towards the second side of the array and moves away from the second side of the array.
4. The reusable molding device of claim 1 further comprising a top pressure plate.
5. The reusable molding device of claim 4 , wherein the top pressure plate encloses a mold volume, wherein the mold volume is a negative space in the array created by the impression of the surface of the object.
6. The reusable molding device of claim 5 , wherein the top pressure plate includes an injection entrance bore through which to pour in a molding material.
7. The reusable molding device of claim 6 , wherein the array and the top pressure plate are separated by a mold volume diaphragm.
8. The reusable molding device of claim 7 , wherein the mold volume diaphragm is a layer that separates the molding material injected into the mold volume from the plurality of pixel pins.
9. The reusable molding device of claim 4 , wherein the top pressure plate is removable.
10. The reusable molding device of claim 1 , wherein each pixel pin of the plurality of pixel pins is a prism to fit tightly next to its surrounding pixel pins.
11. The reusable molding device of claim 1 , wherein each pixel pin of the plurality of pixel pins is of varying sizes to fit tightly next to its surrounding pixel pins.
12. The reusable molding device of claim 1 further comprising a first pressure release stop pin connected to the first clamp pressure plate.
13. The reusable molding device of claim 12 , wherein the first pressure release stop pin sets an amount of pressure released by the first clamp pressure plate on the array.
14. The reusable molding device of claim 1 further comprising a second pressure release stop pin connected to the second clamp pressure plate.
15. The reusable molding device of claim 14 , wherein the second pressure release stop pin sets an amount of pressure released by the second clamp pressure plate on the array.
16. The reusable molding device of claim 1 , further comprising a clamp guide block for controlling the linear movement of the first clamp pressure plate and the second clamp pressure plate.
17. The reusable molding device of claim 1 , wherein the plurality of pixel pins is arranged to form a two-dimensional plane.
