Detailed Description

In order to make the aforementioned and other features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.

As shown in fig. 1-2, the present embodiment provides a double-layer sole forming mold, which includes an upper mold 1, a lower mold 2, and an upper and lower driving assembly 3.

The upper die 1 comprises a first boss 12 and a connecting plate 11, the connecting plate 11 is connected to the upper surface of the first boss 12, the connecting plate 11 is provided with 4 guide holes 13 distributed in a matrix, and the horizontal section shape of the first boss 12 is the same as that of the sole.

The upper surface of the lower die 2 is provided with a forming groove 21, the horizontal section of the forming groove 21 is the same as that of the sole, the forming groove 21 comprises a first cavity 211 and a second cavity 212, the first cavity 211 is positioned at the bottom of the forming groove 21, the second cavity 212 is positioned above the first cavity 211, the sum of the heights of the first cavity 211 and the second cavity 212 is smaller than the depth of the forming groove 21, a feeding channel 26 and a feeding hole 27 are formed in the lower die 2 and positioned on the side wall of the lower die 2, the feeding channel 26 is communicated with the second cavity 212, the upper surface of the lower die 2 is provided with 4 guide posts 22 distributed in a matrix manner, 4 guide holes 13 are matched with 4 guide posts 22, and the guide holes 13 and the guide posts 22 are matched so that the up-down movement of the upper die 1 is more stable. 3 in the lower mould 2 set up cooling channel 23 along the width direction of lower mould 2 equidistant, and vertical cross-section cooling channel 23 encircles the setting along the cell wall of shaping groove 21, sets up the cooling effect like this better.
