Cooling and shaping process, and finally, the finished shoe semi-finished product is removed from the shoe last.

However, the existing overall shoe upper shaping method and equipment have the following deficiencies:

1. Since the shoe last is an integral shoe last, one shoe last corresponds to only one size. Therefore, if you need to produce shoes of different sizes, you need to prepare shoe lasts of multiple corresponding sizes.

2. Since the shoe last is an integral shoe last, the semi-finished shoe is less likely to be put on and removed from the integral shoe last, which is not conducive to the shoe upper shaping process.

In view of this, the main purpose of the present invention is to provide a last setting machine suitable for overall shoe uppers. The last group of the last setting machine includes a last head and a rear part that can be moved relatively. The relative displacement of the head of the last and the rear part changes the total length of the last set, so that the last of the last setting machine can be applied to shoes of various sizes, and the semi-finished shoes can be easily fitted to the last and from the last. Remove the shoe last.

In order to achieve the above-mentioned purpose, the integral shoe upper last setting machine of the present invention includes: A base; and A shoe last set, the shoe last set includes a back heel and a last head, the back heel and the last head can be relatively close to and far away from the base connected to the base.
