Problems solved by technology

[0004] The disadvantages of the above-mentioned prior art are: the die head is heated by means of a heating plate arranged on the side of the die head, resulting in a slow heat conduction rate (after starting up, the working temperature can only be reached after heating for more than 4 hours, and the mold can only be turned off after 4 hours of equilibrium. head heat penetration) and low heat conduction efficiency, so the energy consumption is high, which is not conducive to energy saving

Abstract

The invention relates to a high-heat-conduction-speed energy-saving spinning die head used for a spinning box. The die head comprises a pair of die head bodies symmetrical in structure, and a plurality of segments of square waveform heat conduction oil channels are distributed in the inner walls of the die head bodies; a liquid inlet hole and a liquid outlet hole of each square waveform heat conduction oil channel are connected with a heat conduction oil inlet pipe and a heat conduction oil outlet pipe respectively. According to the spinning die head used for the spinning box, the multiple segments of square waveform heat conduction oil channels are distributed in the inner walls of the die head bodies, the die head bodies are directly heated through heat conduction oil, and therefore the die head used for the spinning box has the advantages of being high in heat conduction speed and heat conduction efficiency and capable of saving energy. The short square waveform heat conduction oil channels are suitable for guaranteeing that all the heat conduction oil inlet holes and all the heat conduction oil outlet holes are consistent basically in flow velocity, and therefore it is guaranteed that the die head is even in bulk temperature, and the production quality of products is improved.
