[0024] Combined with the attached Figure 1 , 2 drawing 3, the upper die mechanism 2 and the lower die mechanism 3 are respectively magnetically connected with an upper die core 4 and a lower die core 5. The upper die mechanism 2 and the lower die mechanism 3 both include a connecting member 22, a placing member 23, a magnetic attraction groove 24, and a cylinder 25.

The pipe orifice of the water inlet pipe 26 faces upward, and the pipe orifice of the outlet pipe 27 faces downward. Before diaphragm forming, the coolant is injected into the cooling water tank 21 by connecting the water inlet pipe 26 to cool the upper die core 4 and the lower die core 5 on the side surface of the cooling water tank 21, thereby accelerating the cooling speed of the diaphragm and improving the thickness uniformity and quality of the manufactured speaker diaphragm. After the diaphragm forming is completed, the coolant inside is conveniently discharged through the downward outlet pipe 27.

[0027] Before the diaphragm is formed, connect the water inlet pipe 26 to inject coolant into the cooling water tank 21 to cool the upper die core 4 and the lower die core 5 on the side of the cooling water tank 21, thereby accelerating the cooling speed of the diaphragm, improving the thickness uniformity and quality of the manufactured speaker diaphragm. After the diaphragm forming is completed, the internal coolant can be conveniently discharged through the downward water outlet pipe 27 to avoid excessive water pipe lines affecting the cleanliness of the tabletop. When the die core needs to be replaced, stop the operation, pull out the upper die core 4 or the lower die core 5 to be replaced from the magnetic attraction groove 24, and then take out other die cores from the placement groove 14 and put them into the corresponding magnetic attraction groove 24.
