Abstract
PURPOSE:To make the bridge material in a mold to be heated by two steps and its effective defoamation and bridge formation to be conducted by controlling the air flow in the gap between a hollow shaft in an oil bath and a mold put in the hollow shaft. CONSTITUTION:In a heating bath 1 with heating oil 4 is installed a hollow shaft which provides a plug 10 with an air inlet 10a at the bottom and to an inserting hole 11a of a fixture 11 with an air outlet 11b arranged on the top of the hollow shaft is inserted a mold 12 with a bridge material 14. First of all, the mold 12 begins to to be heated hanging itself in the hollow shaft in order not to touch its plug 13 with the plug 10 of the shaft 8 and is made to be cooled in order of the air inlet 10a, the gap between the shaft 10 and the mode 12, the air outlet 11b. Then the full defoamation of the bridge material 14 is made to be carried out by heating the mold 12 at a little lower temperature (1st step of increasing temperature). Then the mold 12 is pushed into the lower part, the air is prevented from flowing by touching the plug 10 with the plug 13 and the bridge material 14 is made to be bridged by rapid heating up to higher temperature (2nd step of increasing temperature).
