Abstract
The present invention relates to the field of blow molding, and particularly to a blow molding cooling method for a blow molding machine. The method is characterized in that: compressed air is introduced to the interior of a cavity to carry out blow molding while cooling water is sprayed; and after the cooling water is vaporized inside the cavity, an exhaust duct is opened to exhaust the steam, such that the cavity can be rapidly cooled. The method of the present invention has characteristics of good cooling effect and high production efficiency.
Description
Technical field
The present invention relates to the blow molding field, especially a kind of blow moulding machine blow molding cooling means.
Background technology
At present in the blow-moulding process of blow moulding machine, what be blown into to mold cavity inside all is compressed air, and the inner cooling of die cavity relies on compressed-air actuated flowing to cool off, because the cooling effect of air is limited, has influenced the production efficiency of blow moulding machine.
Summary of the invention
In order to address the above problem, the invention provides a kind of blow moulding machine blow molding cooling means, this method good cooling results, production efficiency is high.
Technical scheme of the present invention is: a kind of blow moulding machine blow molding cooling means is characterized in that: in the blowing of the inner feeding of die cavity compressed air, spray into cooling water; When cooling water behind the die cavity interior evaporation, carry out exhaust steam and make die cavity cool off fast thereby open the exhaust passage again.
Useful technique effect of the present invention: production technology of the present invention is in the process of blow molding, in the blowing of the inner feeding of die cavity compressed air, sprays into cooling water; Because the heat of vaporization of water is more than 100 times of air; So, be used in particular for the inner cooling of parison cooling effect and increase substantially the cooling water that sprays into; In cyclic process, take away great amount of heat, be discharged to the parison outside.Also increase substantially simultaneously production efficiency.
Description of drawings
Fig. 1 is the device structure sketch map of the embodiment of the invention.
The specific embodiment
Further specify the specific embodiment of the invention below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of blow moulding machine blow molding of embodiment of the invention cooling means is inserted air blowing blow needle 3 in the die cavity 2 of blow mold 1, when die cavity 2 feeds compressed air blowing, spray into cooling water through air blowing blow needle 3; When cooling water behind the die cavity interior evaporation, carry out exhaust steam and make die cavity cool off fast thereby open the exhaust passage again.
The above; It only is the preferred embodiment of this invention; Be not that any pro forma restriction is done in invention, every foundation technical spirit of the present invention all still belongs in the scope of the present invention any simple modification, equivalent variations and modification that above embodiment did.
Claims (1)
1. a blow moulding machine blow molding cooling means is characterized in that: in the blowing of the inner feeding of die cavity compressed air, spray into cooling water; When cooling water behind the die cavity interior evaporation, carry out exhaust steam and make die cavity cool off fast thereby open the exhaust passage again.
