Wherein the mold temperature has an effect on the molding cycle in which the cooling time is about 80% of the molding cycle. The cooling water path design principle mainly comprises rapid cooling and uniform cooling.
Traditional cooling water route adopts a straight tube shape water route for linear type injection mold cooling water route to through setting up the water proof piece in the middle of the water route, thereby separate into two cavities in a straight tube, in order to advance water and go out hydrologic cycle, because advance water and go out water and all go on in a straight tube, so the diameter in this straight tube shape water route is thicker.
And current some products, because of the structure restriction has the longer and intensive structure of rib, current cooling water route can't extend to this part, leads to the cooling water route to glue the position far away from the rib is longer and intensive, can't carry out good cooling to this part. The rib of the mould is too deep in the injection moulding production process, the cooling effect is poor, and the drawing mould is seriously deformed when the product is demoulded.
