Circular cooling device for EPS forming machine

Abstract

The invention discloses a circular cooling device for an EPS forming machine, and relates to the technical field of EPS forming machines. Multiple water driving mechanisms are mounted on the inner wall of the upper side of a drying room; axial flow fans are mounted at output ends of the water driving mechanisms; a turbine impeller converts the flowing potential energy of hot water to mechanical energy of self rotation, so that more heat can be dissipated into the drying room in the process, the temperature in the drying room is increased, and EPS foamed models in the drying room are dried; multiple annular bodies are fixedly inserted in an external cavity, so that air formed by the axial flow fans is blown to the EPS foamed models in the drying room after penetrating through the annular bodies, and the drying effect of the EPS foamed models is improved; and as the heat of the hot water is quickly dissipated, cooling water is injected into a water storage tank again through a reflux pipe after heat dissipation, and the cooling water in the water storage tank is injected into a foaming molding machine for cooling the foaming molding machine to enable the hot water and the cooling water to form a circulation.

Description

technical field [0001] The invention relates to the technical field of EPS molding machines, in particular to a circulating cooling device for EPS molding machines. Background technique [0002] When using lost foam casting to produce aluminum alloy products, it is necessary to use a foam molding machine to shape and press EPS (expandable polystyrene) foamed plastic particles into an EPS foam model, and use a foam molding machine to shape and press the EPS foam model Periodic heating, cooling, reheating, and recooling cycles are required. Heating generally adopts electric heating system or steam heating system to heat the forming mold, and cooling generally adopts water cooling device to take away the heat in the forming mold. When cooling in the prior art, the cooling water has a higher temperature, and the heat in the cooling water is generally direct Discharged into the air, not able to rational use. [0003] In the Chinese patent with the authorized announcement number...

Problems solved by technology

[0004] But above-mentioned technical scheme also has following shortcoming: above-mentioned heating device just adopts hot water radiator, so heat dissipation effect is unsatisfactory, and heat dissipation efficiency is slow, thereby makes hot water difficult to become cooling water effectively, has weakened cooling water.
