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
