Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary devices for injection-blowing equipment, in particular to an auxiliary cooling device for plastic injection-blowing products. Background Art

[0002] Injection blow molding is a plastic product processing technology. Its principle is to blow the heated and melted plastic into the mold through high-pressure air, and then quickly cool it into shape. The plastic products manufactured by this method are of high quality and thin walls. It is suitable for manufacturing hollow containers such as bottles and barrels. Injection blow molding devices are widely used in various plastic mold manufacturing fields.

[0003] During the use of the injection blow molding machine, a cooling device is usually used to assist in cooling the processed plastic. For example, patent No. CN210940403U discloses a cooling device for an injection blow molding machine that is easy to install. The cooling device is fixedly installed above the injection blow molding machine mold, and the fan blades are driven by a driving motor to rotate, and the cold air generated by the condensation plate is blown downward to cool the top of the injection blow molding machine mold. Although the cooling speed of the plastic product in the mold is accelerated to a certain extent, since the mold is usually in a closed form, the cooling effect of only blowing from the top is poor, and the fan blades of the device are ordinary blades, the wind force and wind pressure during blowing are insufficient, and the cooling efficiency is low.

The auxiliary blades rotate in the same direction as the main blades. The airflow generated by the auxiliary blades flows toward the main blades along the air duct, and flows outward together with the airflow generated by the main blades, thereby increasing the wind pressure and air volume of the fan body, thereby improving the cooling efficiency.
