The invention discloses a polymeric housed explosion-resistant glue feeding-resistant forming die. The forming die comprises a die frame, a die cavity, a channel, a glue injection aperture, an insulating cylinder and a lining, the die cavity, the channel and the glue injection aperture are communicated, the lining is placed in the insulating cylinder and is cooperated with the insulating cylinder for usage, the polymeric housed explosion-resistant glue feeding-resistant forming die also comprises a protective sleeve, a telescoping apparatus, a left push rod and a right push rod, the protective sleeve is arranged at left end of the lining, the telescoping apparatus is arranged at right end of the lining, the insulating cylinder is arranged between the protective sleeve and the telescoping apparatus, the left push rod is arranged at the die frame of the left end of the die cavity, and the right push rod is arranged at the die frame of the right end of the die cavity. According to the invention, the polymeric housed explosion-resistant glue feeding-resistant forming die has the advantages of simple structure and convenient operation, generation of explosion phenomenon at end part of the insulating cylinder can be effectively avoided, qualified rate of the product is increased, penetration of the rubber compound in the insulating cylinder can be effectively avoided, optimum application amount of the silicone rubber can be fined according to the glue-spilling amount in a glue-spilling groove, so that the product qualified rate can be increased, and material amount for production can be saved.
