What conditions should be met for the cooling water design of plastic mold processing
1. The water transport margin and product material margin are generally not less than 10MM, and should be designed between 10MM-12MM as much as possible; the alloy mold is generally 25MM;
Second, the water delivery margin and the margin settings of the insert needle, thimble, cylinder, insert material are as follows:
①, the inner mold below 200MM, the water delivery margin and the margin of the needle, thimble, cylinder, insert material level are not less than 3.5MM:
②, the inner mold of more than 200MM-400MM, the water delivery margin and the margin of the insert pin, thimble, Secretary tube, insert material level are not less than 4MM;
③, the inner mold of more than 200MM-400MM, the margin of the water transport and the margin of the insert pin, thimble, secretary tube, insert material level are not less than 4MM;
④, the inner mold of more than 400MM-600MM, the water delivery margin and the margin of the insert pin, thimble, secretary tube, insert material level are not less than 5MM;
⑤, the inner mold of more than 600MM, the water delivery margin and the margin of the inserting needle, thimble, secretary tube and insert material level are not less than 8MM;
3. The water transport, gas cap and oil pressure circuit are not less than 8MM;
Fourth, the water transport side and the mouth side of the mouth are not less than 8MM:
Fifth, the water transport side and the inner mold side are not less than 10MM;
Sixth, the distance design of water transportation and water transportation in the same direction:
① When the two pipe joints are in the same direction, the closest distance of the center is not less than 38MM;
② When the pipe joint and the throat plug are in the same direction, the shortest distance from the center is not less than 25MM;
③ When the two laryngeal plugs are in the same direction, the closest distance between the centers is not less than 20MM;
④ When the large mold material area is large, the water transport distance in the same direction, the center distance is generally 60MM;
Seven, the edge of the rubber ring of the water barrier is not less than 2MM; the throat plug and the throat plug are not less than 5MM;
8. Generally, no more than 8 spacers are connected in series for each water transportation circuit, (American fisherman customers require no more than 6 spacers in series;)
Nine, when designing the cooling water of the insert, the closest distance between the transport water and the material level of the insert should be 5MM;
