This utility model discloses a pet supplies injection mold with anti-overflow design. This utility model relates to the field of plastic processing and molding technology. The utility model includes: a support frame, the inner wall of which is fixedly connected to an anti-overflow device; by combining the anti-overflow device and the demolding device, and through precise cylinder control, the pressure of the molding die can be adjusted in real time according to the characteristics of different pet supplies raw materials and the requirements of the injection molding process, effectively preventing molten material from overflowing into the mold gap. Simultaneously, the overflow port on the inner wall of the molding die can collect any small amount of overflowing material, preventing overflow from contaminating the inside of the mold. Combined with the guide structure of the cross and limiting groove, the molding die maintains stable operation during the extrusion of raw materials, reducing component wear caused by shaking or deviation. The demolding device adopts a combination design of a mold body, a bidirectional screw, and a sliding rod. By rotating the bidirectional screw, the mold body can slide symmetrically along the dovetail groove on the inner wall of the support frame, achieving rapid and stable demolding.
