| titleOfInvention | Underwater ultrasonic transducer urethane molding method |
| abstract | (57) [Abstract] [Purpose] In a submersible ultrasonic transducer using a cylindrical piezoelectric device, a secondary urethane mold is attached instead of the positioning pin for the primary mold that is attached to the primary urethane mold. As a result, a secondary urethane mold can be formed, and an excellent underwater ultrasonic wave transmitter / receiver urethane molding method that does not require pretreatment such as degreasing work is obtained. [Structure] Transducer 1 in the center of the primary urethane mold A Are mounted and positioned by a stop pin 10 having a concave tip. Inject urethane from the inlet A1 to 1 Next, urethane molds 7 and 8 are formed. A secondary urethane mold B is attached instead of the stop pin 10. Inlet A Urethane is injected from 2 to form a secondary urethane mold 9. The primary and secondary urethane mold types A and B are removed, and the piezoelectric element 3 is urethane molded to form an underwater ultrasonic transducer. |
