Abstract
The utility model relates to the field of manufacturing of automobile plastic fuel tanks, in particular to an improved blow molding cooling device for a blow molding machine. The improved blow molding cooling device for the blow molding machine is characterized in that the device comprises a plastic blowing mould and a high pressure cooling water valve. And an air inlet blow injector and an air outlet blow injector are inserted in the cavity of the plastic blowing mould, the tail end of the air inlet blow injector is provided with a compressed air inlet and a water inlet, the water inlet is connected with the high pressure cooling water valve, and the high pressure cooling water valve is connected with a high pressure water pump. The high pressure cooling water valve is opened when compressed air is blown into the internal portion of a parison, the high pressure pump presses the high pressure water into the internal portion of the parison to cool, the switching on or off of the high pressure cooling water valve is provided with a time control, when the time is reached, the injection can be stopped, and the cooling water injected into the parison is discharged out of the parison through the air outlet blow injector together with the circulation of the compressed air. The improved blow molding cooling device for the blow molding machine is high in blow molding cooling effect.
Description
Technical field
The utility model relates to the automobile plastic fuel tank and makes field, especially modified blow moulding machine blow molding cooling device.
Background technology
In the blow-moulding process of blow moulding machine, what be blown into to mold cavity inside all is compressed air at present, and the cooling of die cavity inside relies on compressed-air actuated flowing to cool off, because the cooling effect of air is limited, has affected the production efficiency of blow moulding machine.
Summary of the invention
In order to address the above problem, the utility model provides preferably modified blow moulding machine blow molding cooling device of a kind of cooling effect.
The technical solution of the utility model is: modified blow moulding machine blow molding cooling device, its difference is: it comprises blow mold, the high-pressure cooling water valve, be inserted with the air inlet blow needle in the die cavity of described blow mold, the exhaust blow needle, the tail end of air inlet blow needle has a compressed air inlet and a water inlet, described water inlet and high-pressure cooling water valve link, high-pressure cooling water valve and high-pressure hydraulic pump link, the high-pressure cooling water valve is opened to the inner blowing compressed air of parison the time, high-pressure hydraulic pump is pressed into parison inside with water under high pressure and cools off, the switch band of high-pressure cooling water valve is controlled if having time, injecting time reaches and stops to spray, and sprays into the cooling water of parison along with compressed-air actuated circulation is discharged to outside the parison together from the exhaust blow needle.
Useful technique effect of the present utility model: the utility model is in the process of blow molding, when die cavity inside passes into compressed air blowing, spray into cooling water, because the heat of vaporization of water is more than 100 times of air, so, cooling effect increases substantially, and (particularly internal cooling) also increases substantially production efficiency simultaneously.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
Further specify the utility model specific embodiment below in conjunction with accompanying drawing.
As shown in Figure 1, the utility model embodiment modified blow moulding machine blow molding cooling device, it comprises blow mold 1, high-pressure cooling water valve 6, be inserted with air inlet blow needle 4 in the die cavity 2 of described blow mold 1, exhaust blow needle 3, the tail end of air inlet blow needle 4 has a compressed air inlet 5 and a water inlet, described water inlet and high-pressure cooling water valve 6 link, high-pressure cooling water valve 6 and high-pressure hydraulic pump 7 link, high-pressure cooling water valve 6 is opened to the inner blowing compressed air of parison the time, high-pressure hydraulic pump 7 is pressed into parison inside with water under high pressure and cools off, the switch band of high-pressure cooling water valve 6 is controlled if having time, injecting time reaches and stops to spray, and sprays into the cooling water of parison along with compressed-air actuated circulation is discharged to outside the parison together from exhaust blow needle 3.
The above, it only is the preferred embodiment of this utility model, be not that utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of the present utility model any simple modification, equivalent variations and modification that above embodiment does.
