What conditions need to be met for the design of plastic mold cooling water

First, the water transport margin and product material margin are generally not less than 10MM, as much as possible between 10MM-12MM; alloy mold is generally 25MM;  

Second, the water transport margin and the setting margin of the pins, thimbles, barrels, and inserts are as follows:

① For inner molds below 200MM, the water transport margin and the setting margin of pins, thimbles, barrels and inserts shall not be less than 3.5MM:

② For inner molds larger than 200MM-400MM, the water transport margin and the setting margin of pins, thimbles, barrels, and inserts should not be less than 4MM;

③ For internal molds larger than 200MM-400MM, the margin of water transport and the margin of the setting pins, thimbles, barrels and inserts shall not be less than 4MM

④ For inner molds larger than 400MM-600MM, the margin of water transport and the margin of setting pins, thimbles, barrels, and inserts shall not be less than 5MM

⑤ For inner molds larger than 600MM, the water transport margin and the setting margin of the pins, thimbles, barrels, and inserts shall not be less than 8MM;

3.The water transport and gas cap, and the hydraulic circuit shall not be less than 8MM;


Fourth, the water transport side and the pouting side to avoid the air are not less than 8MM: 5.The

water transport side and the inner mold side are not less than 10MM;

Design of distance between water and water in the same direction:

① When the two pipe joints are in the same direction, the closest distance between the centers is not less than 38MM;

② When the pipe joint and the throat plug are in the same direction, the closest distance to the center is not less than 25MM;

③ When the two throat plugs are in the same direction, the closest distance between the centers is not less than 20MM;

④, large die area is larger fill level, carrying water from the same direction, from the center and generally 60MM;

seven, not less than 2MM between the impermeable sheet gasket grooves edges; not less than 5MM between glottal and glottal;

eight , Each transport water circuit generally no more than eight spacers in series, (U.S. fishing Aberdeen customer no more than six spacers in series;)

nine, when the insert design of the cooling water, and the water transport material insert bit nearest distance keeping 5MM ; Water transport and insert side is not less than 3.5MM.
