    • PROBLEM TO BE SOLVED: To mold a sulfur solidified product by replenishing a sulfur-containing material in a supplementary tank under pressure to the inside of a cavity, as the sulfur-containing material filled in the cavity of the mold body cools and shrinks. SOLUTION: In the cavity of the mold body 1, the inside of the outer mold 6 having a hermetically sealable cavity is heated in a set temperature range above the melting point of sulfur. In the supplementary tank 2, the inside can be hermetically sealed by fitting a lid to the upper end opening part 11 so as to be pressurized to a predetermined pressure and heated in the set temperature range. As the sulfur-containing material fully filling the cavity cools and shrinks in the cavity, the sulfur-containing material accommodated in the supplementary tank 2 is replenished into the cavity by the pressure in the supplementary tank 2. Thereby unnecessary time and labor can be saved, strength necessary as the sulfur solidified product can be enhanced and finished appearance becomes fine with the product value increased.

    • 要解决的问题:通过在填充在模具体的空腔中的含硫材料冷却时,将压力下的辅助罐中的含硫材料补充到空腔的内部来模制硫固化产物, 收缩。 解决方案:在模具体1的空腔中,具有气密密封空腔的外部模具6的内部在高于硫的熔点的设定温度范围内被加热。 在辅助槽2中,通过将盖装配到上端开口部11,将内部加压至规定的压力并在设定温度范围内进行加热,能够使内部密封。 由于完全填充空腔的含硫材料在空腔中冷却和收缩,所以容纳在补充罐2中的含硫材料通过补充罐2中的压力补充到空腔中。由此可以节省不必要的时间和劳动 ,随着硫化固化产物的强度和强度的提高,成品外观变细,产品价值增加。 版权所有(C)2010,JPO&INPIT
