Description

Technical Field

[0001] The utility model relates to the technical field of heat dissipation of a heating furnace core shaft, in particular to a heat dissipation fin of a heating furnace core shaft support. Background Art

[0002] The heating furnace device in the rotary automatic bottle blowing machine is a key auxiliary machine of the main machine. The preform needs to be heated and softened before it can be blown into a bottle shape. Modern manufacturers use lamps to heat, and the required heating temperature is very high, but the temperature of the upper part of the support ring on the top of the preform cannot be too hot, otherwise the bottle mouth will deform after blowing. In the past, the mandrel head inserted into the mouth of the preform by the heating furnace was mostly made of stainless steel, which had poor heat dissipation. Overheating would cause damage to the head of the preform. In response to this, we designed an aluminum mandrel support heat sink for the preform head to dissipate heat. Utility Model Content
