The foregoing is an introduction to the various components of the mold heating group 100 and their composition methods provided by a preferred embodiment of the present invention, and then the characteristics of its use are described as follows:

Please refer to FIG. 7, a schematic diagram of the mold heating group 100 being set on a shoe outsole forming machine 80. The shoe outsole forming machine 80 is not the focus of the present invention and will not be described here. When the present invention is in use, the hook unit 14 of the mold 10 is hooked on a transport device 90 of the shoe outsole molding machine 80 (as shown in Figure 6), so that the transport device 90 drives the mold 10 moves.

When the blank (not shown in the figure) is to be put into the mold 10, the lever 154 of the locking unit 15 is first pulled by an external force, and the lever 154 drives the two clasps 153 to pivot to make the buckle The slot 156 is separated from the buckle post 151, so that the second module 12 can be opened, so that the first module 11 and the second module 12 are in an open position (as shown in FIG. 2). Then, the blank material to be heated and shaped can be put into the shaping groove 111 of the first module 11, and then the second module 12 can be pivoted to the closed position, so that the shaping protrusion 121 of the second module 12 Extend into the shaping groove 111 of the first module 11, and then pull the lever 154 in the opposite direction, so that the buckle grooves 156 of the two clasps 153 and the buckle posts 151 on the first module 11 engage The buckle is locked to maintain the first module 11 and the second module 12 in the closed position (as shown in Figure 3).

Then the mold 10 is transported by the transport device 90 to the heater 20 in the open state (as shown in Figure 4), and the pressure cylinder 26 of the power unit 26 1 Actuates to drive the second cover 22 to approach the first cover 21 until the contact is closed (as shown in Figure 5).

In this way, the first heating unit 23 in the first housing 21 and the second heating unit in the second housing 22 will start to generate infrared rays to heat the mold 10 in a non-contact manner. The heating of the first module 11 by the first heating unit 23 and the heating of the second module 12 by the second heating unit is a double-sided heating. Therefore, the heating speed is quite fast, and the heating can be completed in about 100 seconds. Heating and shaping of the inner blank of the mold 10. After the heating is completed, the locking unit 15 is actuated again to start the first module 11 and the second module 12, and the completed shoe sole can be taken out, and the blank material can be put into the next heating operation.

Since the heater 20 heats the mold on both sides in the present invention, its heating efficiency is very good. The heater 20 adopts non-contact heating, and cooperates with the hollowed-out groove 122 on the second module 12 of the mold 10 that penetrates into the shaped convex portion 121, so that the radiant heat conduction is quite fast and can be greatly reduced. The time of operation is convenient for mass production.

In addition, although in the above embodiment, the power unit of the heater adopts a single cylinder to drive the second cover to move. However, in fact, the power unit can also be two pressure cylinders, which are respectively connected with the first cover and the second cover, so as to drive the first cover and the second cover to perform synchronous actions, so as to shorten the operation. The time frame required for the process.
