Then, by turning on the first electromagnet 64, the bottom mold in the brake drum casting mold can be magnetically limited, thereby preventing the bottom mold in the brake drum casting mold from moving upward.

[0032] See Figure 1 、 Figure 4 and Figure 5 The traction assembly 7 includes a gantry 71 arranged on the top surface of the base 1 and located just above the notch 3. The inner cavity of the gantry 71 is provided with an adsorption portion. Guide columns 76 are provided on both sides of the top surface of the adsorption portion.

The two guide columns 76 can be connected to the telescopic ends of the two second electric push rods 78 through the crossbeam 77 and can penetrate the guide holes 75 to install and fix the positioning plate 72. Then, through the extension and contraction of the two second electric push rods 78, the positioning plate 72 can be driven to rise and fall synchronously through the crossbeam 77 and the guide columns 76. Since the top surface of the positioning plate 72 is provided with a plurality of stepped holes 73 distributed in a rectangular array, and each stepped hole 73 is provided with a second electromagnet 74 in the inner cavity, the second electric push rod 78 can be retracted to The position of the positioning plate 72 is adjusted so that the bottom end of the positioning plate 72 can be fitted with the top surface of the top mold in the brake drum casting mold, and by turning on the second electromagnet 74, it can be adsorbed on the top surface of the top mold in the brake drum casting mold, and then the second electric push rod 78 is extended, so that the positioning plate 72 can be driven to move upward, and then the top mold can be lifted synchronously, and then the top mold and the bottom mold can be separated, which is convenient for the staff to take out the cast brake drum.
