The glue scraping bottom cover mold is a functional mold specifically designed for sealants. The formed bottom cover is equipped with an internal glue scraping tooth structure, which can sort out the shape of the glue strip during the extrusion of the sealant, enhancing the convenience of construction. The mold, based on the complex and irregular structure of the rubber scraping bottom cover, adopts a precise multi-parting surface design to ensure that the rubber scraping teeth, sealing rings and other detailed parts are formed completely. The cavity is processed by electrical discharge machining and polishing to ensure a stable glue scraping effect. The mold is made of P20S die steel, which can withstand the high shear force during the formation of the glue-scraping structure and has excellent comprehensive mechanical properties. The cooling waterway is specially arranged for the irregular parts of the rubber scraper teeth, ensuring uniform cooling and avoiding deformation of the rubber scraper teeth caused by shrinkage differences. This mold can be customized with the density and Angle of the glue scraping teeth to adapt to sealants of different viscosities.
