The invention relates to the technical field of foaming forming, in particular to a polyurethane insulation board foaming system. The system comprises a constant-temperature cylinder; a spiral placing frame is mounted in the constant-temperature cylinder; a flowing grid plate is arranged in the spiral placing frame; a discharging port located in the top and a feeding port located in the bottom are formed in the outer wall of the constant-temperature cylinder; the flowing grid plate extends out from the discharging port and enters the constant-temperature cylinder again from the bottom of the constant-temperature cylinder through the feeding port; a rotating shaft is horizontally inserted into the outer wall of the bottom of the constant-temperature cylinder; and a driving wheel for driving the flowing grid plate to flow is mounted at one end of the rotating shaft. The foamed mold is placed in the constant-temperature cylinder to be rapidly cured, the production efficiency can be improved by setting a proper temperature, the mold is gradually moved out through the flowing grid plate which operates at a slow speed in a spiral placing frame, the curing time can be ensured, the requirement for the storage space can also be remarkably reduced, and the product quality and the working efficiency are improved.
Description
technical field [0001] The invention relates to the technical field of foam molding, in particular to a foaming system of a polyurethane thermal insulation board. Background technique [0002] In the foam molding process or foamed polymer material, a cellular or porous structure is formed through the addition and reaction of physical or chemical blowing agents. The basic steps of foam molding are the formation of nuclei, the growth or expansion of nuclei, and the stabilization of nuclei. Under given temperature and pressure conditions, the solubility of the gas decreases, so that it reaches a saturated state, so that the excess gas is removed and bubbles are formed, thereby realizing nucleation. [0003] In the foam molding process, after the raw materials are injected into the mold, it needs to be matured for a period of time. During the curing process, the temperature and pressure of the environment need to be reasonably controlled. Generally, it needs to be matured in th...
