Example Embodiment
[0032] Example one:
[0033] 1. According to the overall shape of the mold, select the number, shape and size of the mold waterway.
[0034] Such as figure 2 As shown, the shape of the mold is basically a cylinder, the lower end is a uniform cylinder 1 with a middle diameter of 20 mm; the upper end is a truncated cone 2 with an upper end surface of 13 mm in diameter.
[0035] The mold has only one water inlet and one water outlet, and one water path fully meets the cooling requirements and flow rate, so the number of water paths is selected as one.
[0036] According to the shape of the mold, the cross-sectional shape of the lower water inlet channel 3 and the outlet water channel 4 is selected as a circle, and the diameter is 4mm. The inlet waterway 3 is a spiral rising type, whose purpose is to maximize cooling effect. The outlet waterway 4 descends along the center, avoiding the inlet waterway 3, and leads to the outlet waterway 4 through a turning structure 5.
[0037] Because the...
Example Embodiment
[0048] Embodiment two:
[0049] 1. According to the overall shape of the mold, select the number, shape and size of the mold waterway.
[0050] Such as image 3 As shown, the mold body 10 is a special-shaped structure, and the whole is a deformed rectangular parallelepiped, about 50mm in length and 14mm in width; one side has an independent special-shaped boss 20, about 11mm in length and 9mm in width, and has a waist at the top. The shaped boss 30 has a length of about 12 mm and a width of about 6.5 mm; the diameter of the water inlet 40 and the water outlet 50 is 6 mm.
[0051] The mold has only one water inlet and one water outlet, temporarily choose one waterway.
[0052] According to the shape of the mold, due to the small size of the special-shaped boss 20 and the waist-shaped boss 30, the cross-sectional shape of the first water channel 60 is conventionally selected as a circle with a diameter of 3mm; because the flow rate of the first water channel 60 is significantly smaller...
