[0033] Reference Figure 2-7As shown, the utility model discloses a forming mold for a filter element part, including a panel 10, an upper movable mold 20, a lower fixed mold 30, a backing plate 40, an ejector plate 50 and a bottom plate 60 from top to bottom, the upper movable mold 20 is embedded with an upper mold core 201, a circular groove 2011 is opened at the bottom of the upper mold core 201, an upper core 2012 is arranged in the circular groove 2011, a lower mold core 301 is embedded in the lower fixed mold 30, the lower mold core 301 is opened with a forming hole, a sleeve 3011 is detachably embedded in the forming hole, a lower core 401 is arranged on the backing plate 40, the lower core 401 is opened with a lower forming groove 4011, and the side wall of the lower forming groove 4011 is circumferentially opened. There are a plurality of first strip grooves 4012, and the sleeve 3011 covers the lower core 401. Specifically, when the mold is closed, the upper mold core 201 and the lower mold core 301 are closed, and the upper core 2012 is placed in the lower molding groove 4011 of the lower core 401. The core is used to form the fixing hole 704 in the middle of the base 701. The outer wall of the upper core 2012 is in contact with the inner wall of the lower molding groove 4011, and the upper core 2012 is circumferentially opened with a plurality of inclined second strip grooves 2013. The first strip grooves 4012 correspond one-to-one to the second strip grooves 2013, and are used to form the ribs 702 that are close to the side away from the base 701. In this embodiment, the first strip groove 4012 includes 8 ribs 702 for molding the filter element part 70, and the circular groove 2011 covers the lower core 401 and the upper end of the sleeve 3011, and is used for molding the base 701 of the filter element part 70, that is, the molding of the filter element part 70.
