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.

The utility model discloses a full concrete outer wall seam drawing structure, which relates to the field of building construction, and comprises a transverse seam drawing plate and a vertical seam drawing plate, the two ends of the transverse seam drawing plate are respectively provided with a clamping structure which can be matched with each other, and the two sides of the clamping structure are provided with gaps for steel bars to pass through. Kidney-shaped holes are formed in the two sides of the vertical seam pulling plate at intervals in the vertical direction. According to the utility model, the installation of the transverse seam-drawing plates can be conveniently realized by splicing the transverse seam-drawing plates at the bottom ends of the steel bars in sequence, and the sliding blocks arranged in the vertical seam-drawing plates in the sliding manner can well block the gaps of the kidney-shaped holes in the vertical seam-drawing plates, so that the installation difficulty of the vertical seam-drawing plates is effectively reduced.
