冷却水孔中心线与型腔壁之间的距离应为冷却水道直径的1至2倍（通常为12

The distance between the center line of the cooling water hole and the cavity wall should be 1 to 2 times the diameter of the cooling water channel (typically 12mm to 15mm), and the center distance between the cooling water channels is about 3 to 5 times the diameter of the water hole . The diameter of the water channel usually exceeds 8 mm. The distance from the cooling water hole to the cavity surface should be as equal as possible. If the wall thickness of the plastic part is uniform, any distance between the cooling water holes and the surface of the cavity should be as equal as possible. If the wall thickness of the plastic part is uneven, the cooling effect should be increased. Strengthen cooling at the gate. <br>The cooling water channel should not pass through the insert or its connection to prevent water overflow. <br>Avoid designing cooling water holes at the joints of plastic parts. The position of the water inlet and outlet pipe joints should be located on the same side of the mold as possible, usually on the back of the injection molding machine. Open the cooling water channel on the mold, and the circulating water immediately cools the mold.

The distance between the center line of the cooling water hole and the cavity wall shall be 1 to 2 times the diameter of the cooling watercourse (usually 12mm to 15mm) and the center distance between the cooling water passages shall be approximately 3 to 5 times the diameter of the water hole. Water passages usually have diameters of more than 8 mm. The distance from the cooling water hole to the surface of the cavity should be as equal as possible. If the wall thickness of the plastic piece is uniform, any distance between the cooling water hole and the cavity surface should be as equal as possible, and if the wall thickness of the plastic part is uneven, the cooling effect should be increased. The gate should be cooled.<br>Cooling water passages should not pass through the panels or their connections to prevent water spillage.<br>Cooling water holes should be avoided at the seams of the plastic parts. The position of the water outlet connection in and out should be located on the same side of the mold as far as possible, usually on the back of the injection moulding machine. Open the cooling watercourse on the mold and the circulating water immediately cools the mold.

The distance between the center line of the cooling water hole and the cavity wall shall be 1 to 2 times the diameter of the cooling water channel (usually 12mm to 15mm), and the center distance between the cooling water channels shall be about 3 to 5 times the diameter of the water hole. The diameter of the water passage is usually more than 8 mm. The distance from the cooling water hole to the surface of the cavity should be as equal as possible. If the wall thickness of the plastic part is uniform, any distance between the cooling water hole and the surface of the cavity shall be equal as much as possible. If the wall thickness of the plastic part is uneven, the cooling effect shall be increased.
