Plastic mould cooling water should be designed to meet the conditions of nine:

A water margin and product level margins generally not less than 10MM, as far as possible in the design of 10MM - 12MM alloy die 25MM in general;
Two, the water margin and inserting needle, thimble, division tube, insert material design margins are as follows:
The internal model, below 200MM, the water margin and inserting needle, thimble, division tube, insert material margin of not less than 3.5MM:
In the model, more than 200MM - 400MM, the water margin and inserting needle, thimble, division tube, insert material margin of not less than 4MM;
In the model, more than 200MM - 400MM, the water margin and inserting needle, thimble, division tube, insert material margin of not less than 4MM;
In the model, more than 400MM - 600MM, the water margin and inserting needle, thimble, division tube, insert material margin of not less than 5MM;
5, more than 600MM model, the water margin and inserting needle, thimble, division tube, insert material margin of not less than 8MM;
Three, water and gas cap, hydraulic circuit is not less than 8MM;
Four, water transport and avoid the empty side sprue is not less than 8MM:
Five, the edge of the water and the inner mold is not less than 10MM;
Six, the same direction of water transport and water design:
Two pipe joints in the same direction, the center of the nearest distance is not less than 38MM;
Second, the pipe joint and a throat the same direction, the nearest center distance of not less than 25MM;
In two, the same throat direction, nearest to the center distance is not less than 20MM;
The material, large mode area is large, the same direction of water transport distance, center distance is 60MM;
Not less than seven 2MM, the water film between the rubber ring grooves of edge; less than 5MM between the plug and plug;
Eight, each water loop is not more than 8 septa (Aberdeen fishing series, customers are not more than 6 U.S. septa series;)
Nine, insert design of cooling water, water transport and insert material recently distance 5MM; water transport and insert edge is not less than 3.5MM.
