The above description is provided for each component of the mold heating assembly 100 and its composition, and the following description is provided for its operation:

referring to fig. 7, the mold heating assembly 100 is schematically disposed on a forming machine 80 of a shoe outsole, and the forming machine 80 of the shoe outsole is not a main point of the invention and will not be described herein. When the present invention is used, the hook unit 14 of the mold 10 is hooked on a transportation device 90 (as shown in fig. 6) of the forming machine 80 of the shoe outsole, so that the transportation device 90 drives the mold 10 to move.

When a blank (not shown) is to be placed into the mold 10, the trigger 154 of the locking unit 15 is first pulled by an external force to drive the two fastening pieces 153 to pivot by the trigger 154, so that the fastening slot 156 is separated from the fastening post 151, and the second module 12 can be lifted, so that the first module 11 and the second module 12 are in an open position (as shown in fig. 2). Then, the blank to be heat-set can be placed into the setting groove 111 of the first module 11, the second module 12 is pivoted to the closed position, so that the setting protrusion 121 of the second module 12 extends into the setting groove 111 of the first module 11, and then the trigger 154 is reversely pulled, so that the fastening grooves 156 of the two fastening pieces 153 are fastened and locked with the fastening posts 151 of the first module 11, and the first module 11 and the second module 12 are maintained at the closed position (as shown in fig. 3).

The mold 10 is transported to the heater 20 in an open state by the transporting device 90 (as shown in fig. 4), and the cylinder 261 of the power unit 26 is actuated to drive the second housing 22 to approach the first housing 21 until the second housing is closed (as shown in fig. 5).

In this way, the first heating unit 23 in the first housing 21 and the second heating unit in the second housing 22 start to generate infrared rays to heat the mold 10 in a non-contact manner, and since the first module 11 is heated by the first heating unit 23 and the second module 12 is heated by the second heating unit in a double-sided manner, the heating speed is very fast, and the heating and shaping of the blank in the mold 10 can be completed in about 100 seconds. After the heating is completed, the locking unit 15 is operated again to open the first module 11 and the second module 12, so that the completed outsole can be taken out and the blank can be put in again for the next heating operation.

Since the heater 20 heats the mold on both sides in the present invention, the heating efficiency is excellent. The heater 20 is heated in a non-contact manner, and the hollow groove 122 of the second mold block 12 of the mold 10 extending into the shaping protrusion 121 is matched, so that the radiation heat conduction is relatively fast, the operation time can be greatly shortened, and mass production is facilitated.

In addition, although in the above embodiments, the power unit of the heater uses a single cylinder to drive the second housing to move. However, in practice, the power unit may also be two pressure cylinders, which are respectively connected to the first housing and the second housing to respectively drive the first housing and the second housing to perform synchronous operation, so as to shorten the time required by the operation process.

It is to be understood that the described embodiments are merely a few embodiments of the invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
