The invention relates to an online cooling device for a packaging bag film and a mounting method of the online cooling device. The online cooling device for the packaging bag film can cool the packaging bag film online efficiently in a high-quality mode and can be suitable for high-speed production and energy-saving production. A cooling bin is arranged at the upper end of a bottom frame, an air inlet is formed in one side of the cooling bin, and an air outlet is formed in the other side; an air outlet of an air cooler communicates with the air inlet of the cooling bin through a pipeline; a first packaging bag film through hole is formed in the front surface of the cooling bin; a second packaging bag film through hole is formed in the back surface of the cooling bin; multiple supporting roller assemblies are arranged in a bin body of the cooling bin; and the hole bottom surface of the first packaging bag film through hole is lower than the uppermost ends of the supporting roller surfaces in the supporting roller assemblies. The online cooling device has the advantages that firstly, the device adopts the cooling bin for cooling, so that the packaging bag film can be cooled online efficiently in the high-quality mode, and the device can be suitable for high-speed production and energy-saving production; and secondly, a mold lifter and a fixed block are arranged in the device, sothat the assembling and disassembling convenience of the cooling bin is improved.

Disclosed is a cooling structure of a beryllium copper sliding block. The cooling structure of the beryllium copper sliding block comprises a sliding block body and a beryllium copper insert, wherein the beryllium copper insert is arranged on the sliding block body. A cooling main water pipe and a cooling main gas pipe are arranged inside the sliding block body, and a cooling auxiliary water pipe and a cooling auxiliary gas pipe are arranged inside the sliding block body and the beryllium copper insert. One end of the cooling auxiliary water pipe is located in the sliding block body and communicated with the cooling main water pipe. The other end of the cooling auxiliary water pipe is located inside the beryllium copper insert and not provided with an outlet. The cooling auxiliary gas pipe penetrates through the cooling main water pipe and the cooling auxiliary water pipe. The end, penetrating out of the cooling main water pipe, of the cooling auxiliary gas pipe is located in the sliding block body and communicated with the cooling main gas pipe, and the end, penetrating out of the cooling auxiliary water pipe, of the cooling auxiliary gas pipe is located in the beryllium copper insert and communicated with a gas valve arranged on the beryllium copper insert. The cooling structure of the beryllium copper sliding block meets the requirement of injection molding products for cooling heat exchange in the curing molding process, improves the cooling effect of a beryllium copper sliding block insert and guarantees the cooling quality of a head molding part of the beryllium copper sliding block insert.
