Abstract
The utility model relates to the piston rod cooling heat insulation structural in a kind of injection-blow molding machine, be installed between injection-blow molding machine piston rod and injection mould, described cooling heat insulation structural comprises transition connecting plate, offer some through holes in described transition connecting plate inside, between described through hole, pass into cooling water by cross current.After have employed said structure, by the cooling-down effect of transition connecting plate, the heat that injection mould passes to piston rod can be completely cut off, ensure that the temperature of piston rod is in normal range (NR), extends the service life of cylinder seal part, increase the cycle of maintenance, increase work efficiency, reduce production cost.
Description
Technical field
The utility model relates to the injection-blow molding machine in injection molding technology field, especially relates to the piston rod cooling heat insulation structural in a kind of injection-blow molding machine.
Background technology
It is former important in Injection Industry that note blows blow moulding machine, mainly by plasticized screw, the raw material of plasticizing note is blown to in-mold molding hollow product, existing injection mould in use, because the temperature of machine injection mould and mold hot cast gate and plastic melt combination machine barrel in article of manufacture process is all more than 220 degree, high temperature is transmitted on piston rod by injection mould, cause cylinder seal part high temperature ageing and leakage of oil makes machine stop production to overhaul, affect production efficiency, improve the cost that dispatches from the factory of product.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of piston rod cooling heat insulation structural that can ensure in the injection-blow molding machine that heat can not be transmitted on piston rod.
The technical scheme in the invention for solving the technical problem is: the piston rod cooling heat insulation structural in a kind of injection-blow molding machine, be installed between injection-blow molding machine piston rod and injection mould, described cooling heat insulation structural comprises transition connecting plate, offer some through holes in described transition connecting plate inside, between described through hole, pass into cooling water by cross current.
Concrete further, in order to make effect of heat insulation more obvious, between described transition connecting plate and injection mould, be provided with thermal insulation board.
Concrete further, described transition connecting plate surface is coated with graphite linings.
Concrete further, described transition connecting plate is provided with radiator fan.
Concrete further, described transition connecting plate surface is cellular.
The beneficial effects of the utility model are: after have employed said structure, by the cooling-down effect of transition connecting plate, the heat that injection mould passes to piston rod can be completely cut off, ensure that the temperature of piston rod is in normal range (NR), extend the service life of cylinder seal part, increase the cycle of maintenance, increase work efficiency, reduce production cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is A-A direction of the present utility model plan structure schematic diagram.
In figure: 1, piston rod; 2, injection mould; 3, transition connecting plate; 4, thermal insulation board; 5, water pipe.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is explained in detail.
Piston rod cooling heat insulation structural as depicted in figs. 1 and 2 in a kind of injection-blow molding machine, be installed between injection-blow molding machine piston rod 1 and injection mould 2, described cooling heat insulation structural comprises transition connecting plate 3, offer some through holes in described transition connecting plate 3 inside, be communicated with by water pipe 5 between described through hole and pass into cooling water; Thermal insulation board 4 is provided with between described transition connecting plate 3 and injection mould 2.
In order to increase radiating effect, described transition connecting plate 3 surface is coated with graphite linings, and graphite linings is conducive to the heat radiation of transition connecting plate 3; Described transition connecting plate 3 is provided with radiator fan, and radiator fan can accelerate the flowing of the superficial air of transition connecting plate 3, improves radiating effect; Described transition connecting plate 3 surface is cellular, adds the surface area that transition connecting plate 3 contacts with air, thus can quick heat radiating.
It is emphasized that above is better implementation column of the present utility model, every above embodiment is done according to technical spirit of the present utility model any simple modification, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
