Rubber member molding die

Abstract

A rubber part forming die, comprising an upper die plate, a lower die plate, a cavity provided on the upper die plate and a core provided on the lower die plate, the rubber part forming die further comprising an integrated exhaust cooling module, the annular main exhaust channel is provided on the side wall of the core, located at 0.5-1.5mm below the product parting surface, a plurality of auxiliary exhaust micro-holes extend from the forming surface of the core and are in communication with the annular main exhaust channel, the cooling channel is arranged around the inside of the core, and part of the pipe wall shares the bottom wall of the annular main exhaust channel to form a heat exchange wall, the vacuum extraction interface is arranged on the side of the lower die plate and is in communication with the annular main exhaust channel through a vertical air guide channel, the auxiliary micro-holes are responsible for capturing deep isolated air bubbles, the main exhaust channel is responsible for collecting and guiding, and the vacuum system creates a negative pressure environment in the initial stage, solving the common problems of air trapping and local overheating.
