Mold for Manufacturing LED Mounting Substrate

Abstract

A mold for manufacturing an LED mounting substrate includes a first molding die and a second molding die, The second molding die covers the first molding die. The second molding die includes a material holding tank, a pressing part and a material inlet channel. The pressing part is protruded on the material holding tank. The pressing part expands along a direction from the first molding die to the second molding die. The material inlet channel is connected between an outer wall of the second molding die and the material holding tank. The material inlet channel shrinks along a direction from the first molding die to the second molding die.

What is claimed is: 
     
         1 . A mold for manufacturing an LED mounting substrate, comprising:
 a first molding die; and   a second molding die covering the first molding die, wherein the second molding die comprises:
 a material holding tank; 
 a pressing part protruded on the material holding tank, the pressing part expanding along a direction from the first molding die to the second molding die; and 
 a material inlet channel connected between one of outer walls of the second molding die and the material holding tank, the material inlet channel shrinking along a direction from the first molding die to the second molding die. 
   
     
     
         2 . The mold of  claim 1 , wherein a cross section of the pressing part and a cross section of the material inlet channel are both symmetrical about a central line of the outer wall where the material inlet channel is located. 
     
     
         3 . The mold of  claim 1 , wherein the pressing part is symmetrical about a central line of the outer wall where the material inlet channel is located, and a cross section of the material inlet channel is positioned outside the central line and is asymmetrical. 
     
     
         4 . The mold of  claim 3 , wherein a height of the cross section of the material inlet channel decreases along a direction away from the central line of the outer wall where the material inlet channel is located. 
     
     
         5 . The mold of  claim 1 , wherein the pressing part is asymmetrical about a central line of the outer wall where the material inlet channel is located, and the central line of the outer wall where the material inlet channel is located crosses a cross section of the material inlet channel, and the cross section of the material inlet channel is asymmetrical. 
     
     
         6 . The mold of  claim 5 , wherein the material holding tank comprises:
 a first material holding groove; and   a second material holding groove, the pressing part separating the first material holding groove and the second material holding groove, and a volume of the first material holding groove is greater than a volume of the second material holding groove;   wherein a height of an edge of a cross section of the material inlet channel that is closer to the first material holding groove is greater than a height of another edge of the cross section of the material inlet channel that is closer to the second material holding groove.   
     
     
         7 . The mold of  claim 5 , wherein a bottom edge of the material inlet channel is symmetrical about the central line of the outer wall where the material inlet channel is located. 
     
     
         8 . The mold of  claim 1 , wherein the material inlet channel comprises:
 an outer opening positioned outside the second molding die for allowing a material from a material supply to entering the second molding die;   an inner opening positioned inside the second molding die and connected to the material holding tank, so as to allow the material entering the second molding die to get into the material holding tank; and   a passage connecting the inner opening and the outer opening;   wherein a cross-sectional area of the inner opening is greater than a cross-sectional area of the outer opening, and the passage expands along a direction from the outer opening to the inner opening.   
     
     
         9 . The mold of  claim 8 , wherein the passage is symmetrical or asymmetrical about a central line of the outer wall where the material inlet channel is located. 
     
     
         10 . The mold of  claim 1 , wherein a width of a cross section of the material inlet channel is less than or equal to a half of a width of the outer wall. 
     
     
         11 . The mold of  claim 1 , wherein a bottom surface of the material inlet channel and a bottom surface of the pressing part are positioned at the same level, and a height of the material inlet channel is less than or equal to a half of a thickness of the pressing part. 
     
     
         12 . The mold of  claim 1 , wherein the outer walls of the second molding die comprises:
 two opposite long walls; and   two opposite short walls adjoined to the long walls;   wherein the material inlet channel is positioned on one of the opposite short walls or one of the opposite long walls.
