Title: Insert molding tool
Inventor: KUWATA SHUSUKE
IPC: B29C33/22
Filed: 1985-07-19
Abstract: PURPOSE:To prevent a molding tool from being damaged owing to the poor insertion of an insert work by a method wherein a detector for the poor insertion of an insert work is equipped on the intermediate plate of a movable retainer plate so as to detect the poor insertion of the insert work under the condition that the mold clamping is once stopped in the state, in which only the weight of the intermediate plate of its own is applied to a retainer plate. CONSTITUTION:Firstly, after the opening of a mold, an insert work 12 is inserted in the core 8 of a retainer plate 3. Secondly, the mold clamping action is done until only the weight of a movable retainer plate 2 of its own is applied to the retainer plate 3. At this time point, the mold clamping action is once stopped so as to judge whether the parting is completed or not through the actuation of a detector for the poor insertion of an insert work 15. If the detector for the poor insertion of an insert work 15 is not depressed and is not brought into actuation, the insertion of the insert work is judged to be poor and a mold is open in order to correct the inserted state of the insert work. If the detector for the poor insertion of an insert work is depressed and is brought into actuation, the insertion of the insert work is judged to be complete and a low pressure mold clamping action is performed. When a detector for the completion of the mold clamping 9 is brought into actuation, the mold clamping is judged to be complete and a high pressure mold clamping is performed and resin is injected to fill the mold. After the injected resin is cooled for the predetermined period of time, the mold is open and an insert molded part is ejected with an ejector pin 13.

Abstract: PURPOSE:To prevent any overflashing and underflashing of an electron gun by holding the maximum value of emission currents developed during the flashing, and displaying the maximum value by reading the value. CONSTITUTION:A flashing voltage 2 is applied to an electric-field discharging electron gun 1, thereby making a flashing current If to flow. At this point,  thermions are developed on the surface of a tip 5, thereby making an emission current Ie to flow.

Thus generated frequency signal is transmitted to a frequency-voltage converter 11, which is located in back of the converter 9, by means of a photosignal transmitter 10, and the voltage signal sent from the converter is held by a hold circuit 12. After that, the voltage held by the circuit 12 is displayed on a display part 7 after being amplified with an amplifier 13. Consequently, the strength of the flashing can be read quentitatively, and any overflashing and underflashing, which may be caused by conventionally used perceptive judgement, can be prevented.
