Light-emitting member and its forming mold
View Patent ↗A forming mold of a light-emitting member includes a frame, an upper mold and a lower mold, and the frame is provided with carriers, pins and supporting portions. The upper and lower molds match with each other to provide a forming space for the base of the light-emitting member. The forming space contains the carriers and a part of the supporting portions. One or more projections are disposed at the position where the brinks of the upper and lower molds contact the supporting portions. After injection molding, the burrs formed by a plastic material along the supporting portions can be concealed in the recesses that are formed corresponding to each of the projections, thereby reducing the influence of the burrs on the external size of the base.
1. A light-emitting member at least comprising:
a frame which is provided with two carriers that are not connected each other, pins that are extended from each of the carriers, and supporting portions that are not connected with each of the carriers; and
a base which envelops the carriers and a part of the supporting portions and is formed with a window to expose the carriers, one or more recesses being disposed at the position where the brinks of the base contact the supporting portions.
2. The light-emitting member in accordance with claim 1 , wherein the recessed depth of the recesses is not beyond the range of the window.
3. The light-emitting member in accordance with claim 1 , wherein the base is provided with an upper mold portion and a lower mold portion.
4. The light-emitting member in accordance with claim 3 , wherein the window is disposed on the upper mold portion.
5. The light-emitting member in accordance with claim 3 , wherein the upper mold portion is provided with a first recess, the lower mold portion is provided with a second recess, and the first and second recesses are located on the same plane.
6. The light-emitting member in accordance with claim 3 , wherein the upper and lower mold portions are injection molded by upper and lower molds.
7. The light-emitting member in accordance with claim 6 , wherein the upper and lower molds match with each other to provide a forming space with a shape corresponding to that of the base, and the lower mold is provided with a gate in fluid communication with the forming space.
8. The light-emitting member in accordance with claim 7 , wherein the upper and lower molds are provided at the position where the brinks of the forming space contact the supporting portions with corresponding to the recesses.
9. The light-emitting member and its forming mold in accordance with claim 8 , wherein the projections of the upper and lower molds are located on the same plane.
10. A forming mold of a light-emitting member at least comprising:
a frame which is provided with two carriers that are not connected with each other, pins that are extended from each of the carriers, and supporting portions that are not connected with each of the carriers; and
an upper mold and a lower mold which match with each other to provide a forming space that contains the carriers and a part of the supporting portions, one or more recesses being disposed at the position where the brinks of the upper and lower molds contact the supporting portions.
11. The forming mold of a light-emitting member in accordance with claim 10 , wherein the upper mold is provided with a window-forming portion that penetrates into the carriers.
12. The forming mold of a light-emitting member in accordance with claim 11 , wherein the depth of the projections is not beyond the range of the window-forming portion.
13. The forming mold of a light-emitting member in accordance with claim 10 , wherein the projections of the upper and lower molds are located on the same plane.
14. The forming mold of a light-emitting member in accordance with claim 10 , wherein the lower mold is provided with a gate in fluid communication with the forming space.
15. The forming mold of a light-emitting member in accordance with claim 10 , wherein the base of the light-emitting member is formed in the forming space after injection molding.
16. The forming mold of a light-emitting member in accordance with claim 15 , wherein recesses corresponding to the projections are disposed at the position where the brinks of the base contact the supporting portions.
