The fixed mold plate 4 is provided with four-side mounting grooves 13 on the fixed mold side and a center mounting groove 14 on the fixed mold side, a four-side insert 15 on the fixed mold side is provided in the four-side mounting grooves 13 on the fixed mold side, and a center insert 16 on the fixed mold side is provided in the center mounting groove 14 on the fixed mold side. The movable mold plate 10 is provided with four-side mounting grooves 17 on the movable mold side and a center mounting groove 18 on the movable mold side, a four-side insert (19) on the movable mold side is provided in the four-side mounting grooves 17 on the movable mold side, and a center insert 20 on the movable mold side is provided in the center mounting groove 18 on the movable mold side.
[0018] Furthermore, upper flow grooves 23 are respectively provided at the lower parts of the four side inserts 15 and the central insert 16 on the fixed mold side, or the lower parts of the four side inserts 15 and the central insert 16 on the fixed mold side are flat.
[0019] Furthermore, the upper portions of the movable mold side four-side inserts 19 and the movable mold side central insert 20 are respectively provided with lower flow grooves 24, or the upper portions of the fixed mold side four-side inserts 15 and the fixed mold side central insert 16 are flat.
[0020] The beneficial effects of the insert interchange device of the plastic partition injection mold of the utility model are as follows: the fixed mold plate 4 is located at the connection between the outer ring mold cavity 11 and the transverse mold cavity 21 and the longitudinal mold cavity 22, and the mold side four-side mounting grooves 13 are set, and the fixed mold side four-side inserts 15 are set in the fixed mold side four-side mounting grooves 13; the fixed mold plate 4 is located at the intersection of the transverse mold cavity 21 and the longitudinal mold cavity 22, and the mold side center mounting groove 14 is set, and the fixed mold side center insert 16 is set in the fixed mold side center mounting groove 14; the movable mold plate 10 is located at the intersection of the outer ring mold cavity 11 and the transverse mold cavity 21 and the longitudinal mold cavity 22 (the fixed mold plate 4 and the movable mold plate 10 are respectively opened). The outer ring mold cavity 11 and the transverse mold cavity 21 and the longitudinal mold cavity 22, the upper and lower mold cavities correspond to each other to form a complete mold cavity) are connected to the movable mold side four-side mounting groove 17, and the movable mold side four-side inserts 19 are arranged in the movable mold side four-side mounting groove 17. The movable mold side center mounting groove 18 is opened at the intersection of the transverse mold cavity 21 and the longitudinal mold cavity 22 of the movable mold plate 10, and the movable mold side center insert 20 is arranged in the movable mold side center mounting groove 18. When the square-shaped plastic partition 100 is to be manufactured, the fixed mold side four-side inserts 15 and the fixed mold side center insert 16 are replaced with a flat structure at the bottom, and the movable mold side four-side inserts 19 and the movable mold side center insert The upper part of the block 20 is also replaced with a flat structure.
