RETAINING MOLD FOR PRODUCING ELECTRONIC PART SEALING ELEMENT AND PRODUCTION OF ELECTRONIC PART SEALING ELEMENT USING THE SAME

摘要

PURPOSE:To obtain a retaining mold hard to deform at the time of the curing of a thermosetting resin sealing material and used many times as compared with a prior art one by forming the retaining mold for producing an electronic part sealing element from a thermoplastic norbornene resin. CONSTITUTION:A retaining mold 1 for producing an electronic part sealing element is formed from a thermoplastic norbornene resin and used in the molding of the seal part of the electronic part sealing element and, usually, a plurality of sealing injection parts are provided so as to be capable of obtaining a plurality of the electronic part sealing elements by one retaining mold 1. In the retaining mold 1 shown in a drawing, five sealing material injection parts 2 are arranged in one row but these injection parts 2 may be arranged in two or more rows. The sealing material is injection into the space of each of the sealing material injection parts 2 of the retaining mold 1 in such a state that an electronic part is arranged in each of the injection parts 2 so as not to come into contact with the inner wall thereof and cured to seal the electronic part.
