The Basic Requirements Of Plastic Mold Cooling Water Design
May 21, 2018

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

Second, the margins of transporting water and inserting pins, ejector pins, division cylinders and inserts are designed as follows:

    1, 200MM inner mold, water edge and insert pin, ejector pin, division tube, insert material margin not less than 3.5MM:

    2, more than 200MM - 400MM of the inner model, the edge of water transport and studs, thimble, Division tube, inserts material bit margin of not less than 4MM;

    3, greater than 200MM - 400MM of the inner mold, transport water margins and studs, thimble, Division tube, insert material margins not less than 4MM; 6 j# M; v5 E-s. ^. p9 n! d

    4, more than 400MM - 600MM inner mold, water edge and insert pin, ejector pin, division tube, insert material margin not less than 5MM; & B, H6 K M3 l'c# n, ]

    5, more than 600MM above the inner mold, water edge and insert pin, ejector pin, Division tube, insert material margins not less than 8MM;

Third, water and gas top, hydraulic circuit is not less than 8MM; 7 r # X3 p" A7 C2 T0 R g $ |

Four, transport water edge and pry mouth to avoid the edge of not less than 8MM: V6 \7 [: k2 E ( F* z( t# n

Fifth, transport water edge and inner mold edge is not less than 10MM;

Six, transport water and transport water in the same direction distance design:

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

   2. When the pipe joint and the gudgeon are in the same direction, the closest distance to the center is not less than 25mm;

  3. When the two throats are in the same direction, the distance between centers is not less than 20mm;

  4, large mold material bit area is larger, the same direction to transport water distance, the center distance is generally taken 60MM;

7. The distance between the aprons of the baffle plate is not less than 2mm; between the glottal plug and the glottal plug is not less than 5mm;

8. In general, no more than 8 septums are to be connected in series for each water transport circuit. (America's customers require no more than 6 septa in series;)

Nine, the insert design cooling water, transport water and insert material position to maintain the closest distance 5MM; transport water and insert edge not less than 3.5MM6 A2 v
