Injection molding mechanism convenient for demolding

The utility model relates to the field of plastic products, in particular to an injection molding mechanism convenient for demolding, which comprises a fixed base, a fixed block is mounted in the middle of the top end of the fixed base, positioning mechanisms are arranged on both sides of the top end of the fixed block, and demolding mechanisms are mounted on both sides of the bottom end of the fixed block. And the demolding mechanism comprises fixing grooves, the fixing grooves are formed in the two sides of the top end of the fixing block, and first pneumatic telescopic rods are installed in the fixing grooves. According to the injection molding mechanism convenient to demold, the ejector block can be pushed out through the arrangement of the first pneumatic telescopic rod, due to the fact that a through groove is blocked by materials during injection molding, the formed materials are ejected out through the fact that the materials continuously bear upward pushing of the first pneumatic telescopic rod and e
