Description

Technical Field

[0001] The utility model relates to the technical field of plastic barrel processing, in particular to a plastic barrel processing cooling device. Background Art

[0002] Plastic barrels are mostly made of polyethylene, polypropylene and other plastics through blow molding and injection molding. Plastic barrels are mostly used for the storage and transportation of various liquids. They have good properties for special hazardous goods packaging. They are not easy to break, rust-proof, and lightweight. They are also oil-resistant and highly corrosion-resistant. They are mostly used for hazardous goods packaging that requires heat preservation, moisture-proof, pressure-resistant, and corrosion-resistant. In the process of processing plastic barrels, plastic barrels are usually injection molded. When injection molding plastic barrels, they need to be cooled. When cooling plastic barrels, plastic barrel processing cooling devices need to be used.

[0003] In the prior art, there are the following problems:

[0004] After injection molding of a conventional plastic barrel, the barrel needs to be cooled to solidify the barrel. The existing cooling device introduces a coolant into the mold to cool the plastic barrel after injection molding. However, when the existing cooling device introduces the coolant into the mold, it is not convenient for the coolant to flow around the plastic barrel, and it is not convenient to cool the inside and outside of the plastic barrel after injection molding simultaneously, so the cooling effect is relatively general. At the same time, after the coolant cools the plastic barrel, the coolant absorbs heat, resulting in a high temperature of the coolant, which is not convenient for cooling the coolant and recycling the coolant.
