What conditions should the cooling water design of plastic mold meet?
1、 The edge distance between water conveyance and product material level shall not be less than 10MM generally, and shall be designed between 10MM and 12MM as far as possible; Alloy die is generally 25MM;
2、 The design of water transport margin and insert needle, thimble, ejector sleeve, insert material level margin is as follows:
① The edge distance between the water conveyance edge and the insert pin, thimble, barrel and insert material level of the internal mold less than 200MM shall not be less than 3.5MM:
② For the internal mold larger than 200MM - 400MM, the distance between the water carrying edge and the level of insert pin, thimble, barrel and insert shall not be less than 4MM;
③ For the internal mold larger than 200MM - 400MM, the distance between the water carrying edge and the level of insert pin, thimble, barrel and insert shall not be less than 4MM;
④ For the internal mold larger than 400MM - 600MM, the distance between the water carrying edge and the level of insert pin, thimble, barrel and insert shall not be less than 5MM;
⑤ . For internal formwork larger than 600 mm, the distance between the water carrying edge and the inserted pin, thimble, barrel and insert material level shall not be less than 8 mm;
3、 The water conveyance, gas cap and oil pressure circuit shall not be less than 8MM;
4、 The water carrying edge and the air avoiding edge of the pump mouth shall not be less than 8 mm:
5、 The water conveying edge and internal mold edge shall not be less than 10MM;
6、 Distance design in the same direction of water transportation and water transportation:
① . When two pipe joints are in the same direction, the nearest distance between centers shall not be less than 38MM;
② . When the pipe joint and the throat plug are in the same direction, the nearest distance from the center shall not be less than 25MM;
③ . When two throat plugs are in the same direction, the nearest distance between centers shall not be less than 20MM;
④ . When the area of large mold level is large, the water transportation distance in the same direction is generally taken as 60MM;
7、 The distance between groove edges of water separator rubber ring shall not be less than 2MM; The distance between the laryngeal plugs shall not be less than 5MM;
8、 Generally, no more than 8 spacers are connected in series for each water conveyance circuit (American fisherman customers require no more than 6 spacers connected in series;)
9、 When the insert is designed with cooling water, the nearest distance between the water delivery and the insert material level shall be 5MM; Water delivery and insert edge shall not be less than 3.5mm.
