[Prior art] As shown in Figures 1, 2, and 3, the method for manufacturing a foamed material with a large number of through-holes 'is to first heat and press an unfoamed substrate to make it a foamed substrate 1'. The foamed substrate 10 is then placed in a mold 20 to be molded into a molded foamed substrate 11. The mold 20 has a top mold 21 and a bottom mold 22 provided with a plurality of opposite convex columns 211 and 221. Therefore, the molded foamed substrate 11 has a plurality of top blind holes 12 formed from a top surface 101 toward a bottom surface 102, and a plurality of bottom blind holes 13 formed from the bottom surface 102 toward the top surface 101.

Although the above manufacturing method can produce the first foamed material 14 having the through-holes 120 and the second foamed material 15 with the through-holes 130, the first foamed material 14 and the second foam can be continued. The material 15 is made into an insole (not shown), but the following defects still exist in practice: 1. The above manufacturing method can only obtain the first foamed material 14 having the through-holes 12 and the through-hole 13. Only the second foamed material 15 is lacking. 1230118 2. The third foamed material 16 produced after the Xian operation has no practical value and is often discarded. There is a lack of wasteful materials. …,-Because the foaming rate is not-, the perforations 120 and 13G obtained by each foaming are incorrectly set, and the perforations of the left and right insoles cannot be uniformly and uniformly missing. 4.
