Description

Technical Field

[0001] The present application relates to the technical field of plastic film blowing molds, in particular to an IBC film bubble internal cooling film blowing mold. Background Art

[0002] Films made of polyvinyl chloride, polyethylene, polypropylene, polystyrene and other resins are used for packaging and as coating layers. Plastic packaging and plastic packaging products occupy an increasingly larger share in the market, especially composite plastic flexible packaging, which has been widely used in food, medicine, chemical and other fields, among which food packaging accounts for the largest proportion, such as beverage packaging, quick-frozen food packaging, steamed food packaging, fast food packaging, etc. These products have brought great convenience to people's lives.

[0003] In current blown film molds, general cooling is achieved through air holes inside the mold and air rings installed above the mold. However, when the product needs to increase production, the low cooling efficiency of the air ring can easily lead to stagnation, discoloration, and burning, which can lead to a decline in product quality.

[0008] Preferably, in the above-mentioned IBC film bubble internal cold blown film mold, the air inlet channel is connected to the bottom end of the cavity.

[0009] Preferably, in the above-mentioned IBC film bubble internal cold blown film mold, the number of the air inlet flow channels is the same as the number of the air outlet flow channels.

[0010] Preferably, in the above-mentioned IBC film bubble internal cooling blown film mold, the first air duct and the second air duct are coaxially arranged.

[0011] Compared with the prior art, the advantages of the utility model are:

[0012] The external gas and the gas in the air inlet channel form a cycle after passing through the cavity, the through hole, the first air duct, the diverter and the air outlet channel, thereby improving the cooling efficiency, reducing the excessive temperature caused by increasing the production capacity, thereby reducing the occurrence of stagnation, discoloration and burning, thereby improving work efficiency and improving the qualified rate of finished products.
