The slide rail 421 is hollow, and its interior is filled with refrigerant to lower the temperature of the last 43 so as to facilitate the shaping of the toe after bending. The arc-shaped design of the utility model can increase the surface area of the slide rail 421 to make the temperature conduction effect better; on the other hand, it can increase the internal evaporation space to increase the effect of the refrigerant; moreover, the circular shape The arc-shaped sliding rail 421 and the sliding groove 431 make the loading and unloading of the last 43 smoother, which is better than the traditional polygonal dovetail groove.

During operation, as shown in Figure 7, the toe cap push plate 32 is pulled out for a certain distance, and then the toe cap (A) softened by heat pressing of the heat pressing device is laid flat on the Toe cap push plate 32 top surface (please also refer to shown in Fig. 9). Push the toe cap push plate 32 in again, then step on the pedal to start the pressing cylinder 11 of the cold pressing device 10, and drive the pressing mechanism 20 to move downward. As previously mentioned, the pressing rod 225 on the pressing mechanism 20 is lower than the pressing die 23, and the distance between the two is about the thickness of the toe leather to be pressed. When the pressing mechanism 20 moves downward, the pressing rod 225 and the pressing die 23 are respectively pressed on the base plate 31 and the surface of the toe cap (A) of the placement mechanism 30 (as shown by the imaginary lines in the figure), and the base plate 31 is pressed down by the pressing rod 225 . At this time, the bottom mold mechanism 40 also rises as shown in FIG. high. At this time, start the switch, so that the push rod 224 inside the joint seat 22 shown in Figure 6 is pressurized and pushed out, so that the die 23 is squeezed inward, that is, the toe cap (A) is pressed tightly on the periphery of the last 43 to shape, And the toe cap (A) is cooled and shaped by the low-temperature last 43.

Both sides of the top surface of the fixing seat 21 of the pressing mechanism 20 are respectively fixed to a seat block 211 , and the top surface of the seat block 211 protrudes upwards with guide rods 212 passing through the protruding seat 112 and the guide seat 111 . The guide rod 212 is fixedly connected with the protruding seat 112 and is guided by the guide seat 111 for lifting. However, in order to adapt to different types or sizes of toe caps, it is necessary to adjust the descending position of the pressing mechanism 20, such as smaller shoes, the height of the toe cap is relatively small, so the pressing mechanism 20 does not need to descend too deeply. In order to achieve the purpose of adjusting the pressing mechanism 20, the utility model is characterized in that the top end of one of the guide rods 212 is set as a threaded part 213, and a stopper 214 is screwed on the threaded part 213. When the bottom edge of the stopper 214 touches the top edge of the guide seat 111 , even if the pressing mechanism 20 is blocked and cannot descend, so when it is desired to form different types of toe caps (A), the height of the stopper 214 can be adjusted by rotation.

Also as shown in Figure 5, in order to allow several structures of the present utility model to adjust the displacement, the bolts are fitted with long grooves between the fixed seat 21 and the joint seat 22 of the pressing mechanism 20, and between the seat block 211 and the fixed seat 21. Connected so that the combination seat 22 and the die 23 can be moved back and forth, left and right, and adjusted. The fixing seat 21 and the top of the pressure rod 225 are also threadedly connected by bolts 226, so as to adjust the protruding distance of the pressure rod 225 to meet the needs of different toe cap thicknesses.
