The utility model content
The technical problems to be solved in the utility model is to provide a kind of cooling water channel structure of bottle blowing bed die, water channel evenly distributes along the curve of bottle pawl lobe groove, so that cooling water carries out cooling to bed die equably, reduce cool time, and then reduce the consumption of the energy and enhance productivity, avoid simultaneously affecting product quality because of the inequality of being heated.
the cooling water channel structure of bottle blowing bed die described in the utility model, comprise the end core that is provided with bottle bottom shape groove, with core print seat of the close-fitting end, the bottom of end core, end core and end core print seat are provided with cooling water channel, described cooling water channel comprises water inlet and the delivery port that is arranged on end core print seat, be arranged at the center water channel of end core centre bottom, the center water channel is connected with water inlet, end core tilt arrange and with the even close branch water route of the bottom curve of groove, be provided with water annulus on end core or end core print seat, water annulus is connected with delivery port, the loop that also has connected component water route and water annulus.
the cooling water channel structure of bottle blowing bed die described in the utility model, have the groove consistent with the bottle bottom shape on end core, end core and end core print seat are provided with cooling water channel, cooling water channel comprises water inlet, the center water channel, the branch water route, the loop, water annulus, and delivery port, cooling water flows into the center water channel from water inlet, therefrom the edema with the heart involved road branches to each road branch water route again, the quantity in branch water route is looked the shape setting of different bottles, consistent with bottle pawl lobe number, the branch water route is to be obliquely installed, and mutually evenly close with the curve of groove, the cooling water that flows out from the branch water route flows into water annulus through the loop, flow out from delivery port at last.The cooling water channel structure of described bottle blowing bed die, the branch water route is obliquely installed and is mutually evenly close with the curve of groove, the bottle embryo that can process blowing equably carries out cooling, avoid the heat concentration of local, need to consume the more energy and time, and the defective that produces because of the inequality of being heated at the bottom of avoiding bottle; Cooling water flows into loop and water annulus through the branch water route, take full advantage of the water source and bed die is proceeded cooling, accelerates cooling velocity, enhances productivity.
