Title: Combustion safety device
Inventor: KUMAZAWA KATSUYOSHI
IPC: F23N5/24
Filed: 1980-06-23
Abstract: PURPOSE:To prevent the carbon monoxide poisoning accident due to incomplete combustion by a method wherein, in case of oxygen shortage, a detecting element produces a large output enough to close a safety valve through a control circuit. CONSTITUTION:At the start of combustion, the flame and combustion exhaust gas is directed toward the open part formed by a guide duct 2 and a crown plate 5 and the detecting element 3 produces a very small signal due to its contact with the air in the atmosphere. Utilizing the signal, the ignition is confirmed through a control circuit 7. On the other hand, in case of oxygen shortage, the flame extends to raise the temperature near the crown plate 5 and the crown plate 5 closes the open part at the upper part of the guide duct 2 by the action of a bimetal 6 todirect the flame in the guide duct 2 to burn downward. At this time, being covered with the high temperature exhaust gas and unburnt gas, the detecting element 3 produces enough electromotive force to close the safety valve 8 through the control circuit 7, thereby preventing the accident due to oxygen shortage.

Then at the time of performance of injection molding of a multi-color molded article composed of a primary molded article 30 and secondary molded article 31 by moving the core 13 backward under a mold clamping state caused by straight pressure and applying secondary injection to the cavity 10 generated there, mold clamping force at the time of backward movement of the core 13 is depressurized to secondary mold clamping pressure which is lower than primary mold clamping pressure, and then the secondary injection is performed by boosting up the mold clamping force to tertiary mold clamping pressure which is higher than the secondary mold clamping pressure. With this construction, as the backward movement of the core 13 under a mold clamping state is performed by depressurizing the mold clamping force, sliding resistance of the core 13 is reduced, movement of the core is performed smoothly and galling becomes hard to occur.
