Pressing-shaping method for manufacturing circular cooling base for being embedded with fins and mold used in the method

Abstract

A pressing-shaping method for manufacturing a circular cooling base for being embedded with fins and a mold used in the method are disclosed. The method includes providing a blank ingot that has a first surface, a second surface, and a lateral circular surface encircling the rims of the first and second surfaces. The method further includes using a mold to press the blank ingot to cause the first surface of the blank ingot to indent inward to form a groove, and to cause a plurality of clipping grooves to be formed on the lateral circular surface of the blank ingot through extrusion. As a result, the blank ingot is shaped into the circular cooling base for being embedded with fins.

1 . A pressing-shaping method for manufacturing a circular cooling base for being embedded with fins, the method comprising:
 a) providing a blank ingot that has a first surface, a second surface, and a lateral circular surface encircling the rims of the first and second surfaces; and   b) using a mold to press the blank ingot to cause the first surface of the blank ingot to indent inward to form a groove, and to cause a plurality of clipping grooves to be formed on the lateral circular surface of the blank ingot through extrusion;   wherein after steps a) and b) the blank ingot is shaped into the circular cooling base for being embedded with fins.   
     
     
         2 . The method of  claim 1 , wherein the blank ingot provided in step a) is a solid cylinder. 
     
     
         3 . The method of  claim 1 , wherein the blank ingot provided in step a) is an aluminum blank ingot. 
     
     
         4 . The method of  claim 1 , wherein step b) further causes the second surface of the blank ingot to form a plane. 
     
     
         5 . The method of  claim 1 , further comprising:
 after step b), embedding a plurality of fins onto the clipping grooves.   
     
     
         6 . The method of  claim 5 , further comprising:
 assembling a circular lid to the bottom edges of the fins.   
     
     
         7 . A mold for being used in the pressing-shaping method of  claim 1 , the mold comprising:
 a male mold, extruded with a groove shaping part for causing the first surface of the blank ingot to form the groove; and   a female mold for working in coordination with the male mold, the female mold being indented with a mold cave space, the inner wall of the mold cave space being indented with a plurality of circularly arranged teeth, the circularly arranged teeth being for causing the lateral circular surface of the blank ingot to form the clipping grooves.   
     
     
         8 . The mold of  claim 7 , wherein on the inner wall of the mold cave space of the female mold, a clipping arm shaping part is formed on each of the two sides of each of the teeth. 
     
     
         9 . The mold of  claim 8 , wherein the teeth and a plurality of separation teeth are formed alternately on the inner wall of the mold cave space of the female mold. 
     
     
         10 . The mold of  claim 7 , wherein the teeth and a plurality of separation teeth are formed alternately on the inner wall of the mold cave space of the female mold.
