Detailed Description
As shown in fig. 1 and 2, the independent detachable shoe last comprises a base 1 and a shoe last 10, wherein a mounting seat 2 and a locking power source 4 are arranged on the base 1, a left locking block 5 and a right locking block 5 are connected to the mounting seat 2, the middle part of the locking block 5 is hinged to the mounting seat 2, as shown in fig. 3, a locking hook part 50 is arranged on the inner side of the upper end of the locking block 5, a stress inclined surface 51 is arranged on the inner side of the lower end of the locking block 5, a top block 6 in transmission connection with the locking power source 4 is arranged between the two locking blocks 5, the top block 6 is provided with an action inclined surface 61, the action inclined surface 61 of the top block 6 can act on the stress inclined surface 51 of the locking block 5, the lower end of the locking block 5 is hinged to one end of a connecting arm 9, and the other end of the connecting arm 9 is hinged to the top block 6; as shown in fig. 1, the last 10 is connected to the connection block 8, the side surface of the connection block 8 has a locking groove 80, and the locking hook 50 of the locking block 5 can be locked in the locking groove 80 of the connection block 8.
The working principle of the independently detachable shoe tree is as follows: as shown in FIG. 1, a shoe last 10 is connected to the connecting block 8, and the vamp is sleeved on the shoe last 10; when the shoe upper is required to be pulled, the connecting block 8 is placed between the left locking block 5 and the right locking block 5, the locking power source 4 drives the top block 6 to move upwards, the action inclined plane 61 of the top block 6 acts on the stress inclined plane 51 of the locking block 5, the top block 6 rotates, the lower end of the top block 6 moves outwards, the upper end of the top block 6 moves inwards, the locking hook part 50 at the upper end of the locking block 5 is clamped in the locking groove 80 of the connecting block 8 to lock the connecting block 8, and the last 10 is fixed to carry out the shoe upper pulling process; when the shoe upper is required to be clamped, the locking power source 4 drives the top block 6 to move downwards, the top block 6 drives the top block 6 to rotate through the connecting arm 9, the lower end of the top block 6 moves towards the inner side, and the upper end of the top block 6 moves towards the outer side, so that the locking hook part 50 at the upper end of the locking block 5 comes out of the locking groove 80 of the connecting block 8, the connecting block 8 is not locked any more, the shoe last 10 can be taken down, and the shoe last 10 is shorter, so that the shoe upper can be taken to the shoe upper clamping machine for front shoe upper clamping and rear shoe upper clamping.
Through the structure, the problems of the tightening of the edge of the bottom of the vamp and the shoe last clamping operation in the shoe manufacturing process can be solved, the quality and the precision of the injection molding of the sole are improved, and the manufacturing process is simplified. This positively affects the productivity and product quality of the shoe manufacturing industry.
In order to facilitate the rapid positioning of the connecting block 8, the utility model is provided with two positioning rods 7 on the mounting seat 2, and the connecting block 8 is provided with two positioning holes for respectively allowing the two positioning rods 7 to enter. When placing last 10, as long as with two locating holes on connecting block 8 with two locating lever 7 on mount pad 2 align, let two locating lever 7 enter into two locating holes respectively, just so can make the placing position of connecting block 8 confirm down to be favorable to placing fast of last 10.
In order to prevent the last 10 from shaking when the locking block 5 is in the locked state, the utility model installs the spring pin 3 on the mounting seat 2, and as shown in fig. 3, the top block 6 is provided with a pin hole 60, and when the locking block 5 is in the locked state, the spring pin 3 can be pinned into the pin hole 60 of the top block 6. The stability of the last 10 during locking can be further improved through the action of the spring pin 3, and the stable performance of the pull-up side is ensured; even if the locking power source 4 fails, the locking block 5 does not loosen.
The locking power source 4 may be a motor or a cylinder, and when the locking power source 4 is a cylinder, a piston rod 40 of the cylinder is connected with the top block 6. The top block 6 can be driven to move up and down by ventilation and deflation of the air cylinder.
For easy connection with the shoe machine, the base 1 of the present utility model has extension edges 11 on both sides. When the shoe last 10 is connected, the shoe last 10 can be downward, the base 1 can be upward, and then the base 1 can be inserted into the connecting groove of the shoe machine by means of its two extending edges 11, so that it can be used for injection moulding shoe soles.
Finally, it should be noted that the inner end of the locking groove 80 of the connecting block 8 is provided with an inner recess 81, as shown in fig. 4, and the inner end of the locking hook 50 of the locking block 5 can be embedded into the inner recess 81. When the cylinder is out of air, the shoe last 10 vibrates, the inner end of the locking hook part 50 of the locking block 5 is sunk inwards, and the effect that the shoe last cannot loosen due to vibration is achieved.
