Conditions for cooling water for 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;
2, 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;
4. the water transport side and the mouth side of the mouth are not less than 8MM:
5. the water transport side and the inner mold side are not less than 10MM;
6. 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;
7.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;)
9, 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;
