Abstract

PURPOSE:To facilitate the exchange of an individual sheath heater by interposing an inorganic adhesive having high thermal conductivity and brittleness at the time of hardening between a cartridge type heater fitted into a through- hole of a heating member and the through-hole. CONSTITUTION:The cylindrical cartridge type heater (sheath heater) 4 is fitted to be fixed into a heater supporting hole 3C penetrating the heating member (back plate) arranged on both sides of a metallic molds 1 in a mold carrier 2. At the time of fitting this sheath heater 4 into the heater supporting hole 3C, the inorganic adhesive 6 having high thermal conductivity and brittleness at the time of hardening is applied around the outer cylinder of the sheath heater 4 or the adhesive 6 is packed in the supporting hole 3C side to fill the gap between the heater 4 and the heater supporting hole 3C with the adhesive 6. At the time of exchanging the heater 4 due to the disconnection of wire, etc., the inorganic adhesive 6 is broken by giving shock to the end part of the heater body and the fixed state can easily be eliminated.

2. Description of the Related Art In a mold that can be repeatedly used as a mold for casting and solidifying cast metal or molten resin-based material, the temperature distribution in the mold such as the thickness change part is not appropriate. Shrinkage cavities, cracks, and defects such as around the hot water tend to occur. In particular, such a problem is remarkable in the gravity type casting mold.

However, in the above disclosed example, the heater is directly loaded into the heat conductor, and the heat conductor is mounted on the mold.
Therefore, the gap between the heater loading portion and the heater becomes a problem. That is, in general, the coefficient of thermal expansion differs between the heater and the heat conductor. Therefore, if the play between the heater and the heat conductor is increased in consideration of this, the air present in the gap of the play impedes heat conduction. Therefore, there is a possibility that heating will not be performed effectively. Thus, a large amount of electric power is required to reach the set temperature, which not only shortens the life of the heater but is economically unfavorable. On the contrary, if the above-mentioned play is reduced, when the heaters are broken due to mutual deformation, they cannot be removed from the heat conductor, resulting in a forced replacement.
