[0023] The outer wall of the other end of the threaded rod 28 is installed with a worm wheel 26, and the outer walls of both sides of one end of the upper mold 11 are installed with knobs 12, and one end of the knob 12 is connected to a worm 27, and a meshing transmission structure is formed between the worm 27 and the worm wheel 26;

[0024] Specifically, Figure 1 , Figure 4 and Figure 5 As shown, when this structure is used, the worm 27 is rotated by rotating the knobs 12 on both sides, and the threaded rod 28 is rotated at the same time through the engagement of the worm 27 and the worm wheel 26.

[0030] Working principle: When using this device, firstly, the pneumatic telescopic rod 13 is used to press the upper mold 11 onto the lower mold 4, and at the same time, the positioning block 6 is positioned in the positioning groove 14, and then the molten metal enters the mold groove 15 through the molten metal hole 9, and is heated by the heating plate 10 to prevent the molten metal from cooling down.

[0033] Step 2: The high temperature of the melt is absorbed by the heat conducting rod 17, and then the high temperature is transferred to the heat conducting plate 20, and the fan 21 blows the ice cubes in the ice cube box 19, and the formed cold air blows to the heat conducting plate 20 to quickly cool down the melt in the mold cavity 15, thereby quickly cooling down the melt into shape;

[0034] Step 3: The water that absorbs heat after spraying is drawn into the circulation box 1 through the circulation pump 2, and then enters the refrigerator 22 for refrigeration through the input pump 23. The refrigerated water then enters the cold water tank 18 to realize the cold water circulation in the cold water tank 18.

[0035] The second innovation point implementation steps:

[0036] The worm 27 is rotated by rotating the knobs 12 on both sides, and the worm 27 is meshed with the worm wheel 26 to rotate the threaded rod 28 at the same time. The threads cooperate to move the clamping rod 24 to the side away from the clamping slot 25, and then the pressing module 7 can be removed for replacement, which is convenient for replacing different pressing modules 7, thereby processing locks with different patterns.
