Investigation of cooling process by thermovision A very important issue for geometrical shape of seats is proper selection of cooling parameters and cooling posi-tion. This part of research was made to investigate defor-mation of a seat due to different storing position during cooling. Cooling was performed in environment condi-tions. Four cooling positions were investigated. They all are shown on Fig. 12.
The research was aimed to find out which of the position causes the smallest deviation in cold state. Measurement results are shown on the Figs. 13–16. Each of them presents deviations on a view from the top and from the left side.
Basing on these results V free position was chosen for further analysis using thermography.
Temperature distribution with a seat just after opening the mold was shown on Fig. 17 and seat during cooling on Fig. 18. +1.5943 +1.1370 -0.8900 +1.1528 +1.7208 -0.9461 +0.1129 -0.9782 +0.2041 +0.0594 -0.6827 -0.4512 -1.3178 -0.2280 -1.5011 0 -100 -200 -300 -400 100 200 300 400 -800 -600 -400 -200 0 200 400 600 X Y Z +0.4478 -0.1055 +0.8627 +1.2169 -0.1111 +1.3335 -0.3753 -1.2414 -0.9113 +1.6519 +0.9779 -800 -600 -400 -200 0 200 400 600 -1000 -.01704 +0.0228 -0.1982 -0.6822 -0.2172 -0.2221 -1.7043 200 300 400 500 600 100 0 -100 -200 Z X Y 0.0 0.4 0.8 1.2 1.6 2.0 mm -0.4 -0.8 -1.2 -1.6 -2.0 +2.1253 +0.8591 +0.2274 +0.7740 +0.3794 +1.1373 -0.8970 +0.2495 -1.0025 +0.3702 +0.1530 -0.8903 -0.6138 -1.0077 +0.0327 -1.3497 0 -100 -200 -300 -400 100 200 300 400 -800 -600 -400 -200 0 200 400 600 X Y Z +0.4478 -0.1055 +0.8627 +1.2169 -0.1111 +1.3335 -0.2497 -0.9711 -0.7863 +1.8238 +1.1791 -800 -600 -400 -200 0 200 400 600 -1000 +0.0049 +0.0886 -0.1318 -0.5403 -0.2098 -0.2301 -1.5722 200 300 400 500 600 100 0 -100 -200 Z X Y 0.0 0.4 0.8 1.2 1.6 2.0 mm -0.4 -0.8 -1.2 -1.6 -2.0 +2.1253
