A shoe last holding device for clamping a shoe last including two spaced-apart clamped portions includes a base seat unit, a driving unit, and a clamping unit. The driving unit includes a pushing member movable relative to the base seat unit. The clamping unit includes two spaced-apart clamping elements pivotally mounted to the base seat unit. Each clamping element includes a force transmission end abutting against the pushing member and a clamping end opposite to the force transmission end. The pushing member is disposed between and movable toward and away from the clamping elements to drive the clamping elements to convert between a releasing state and a clamping state where the clamping ends engage the clamped portions, respectively.

A method for automatically pulling a shoe upper onto a last using a robot which includes a robot controller, a robot arm controlled automatically by the robot controller, and a gripper which is moved by the robot arm and which is designed to hold a shoe upper.

A toe-cap molding machine has a body, a clamping device and a shoe-tree mount. The body has a base panel, a connecting mount, a clamping cylinder and a shoe-tree cylinder. The clamping device is detachably connected to the body and has two quick-release groups and a mold group. The quick-release groups are securely mounted on the assembling panel, and each has a quick-release mount, a clamping mount and a first spring. The quick-release mount has a releasing hole, a holding pin and a mounting recess. The clamping mount is pressably connected to the quick-release mount and has an engaging block, an elongated hole and an engaging head. The mold group is connected to the quick-release groups and the assembling panel and has two guiding shaft, a limiting panel, two second springs and a clamping mold. The shoe-tree mount is detachably connected to the shoe-tree cylinder below the clamping device.
