[0031] Reference Figure 1-Figure 4The high-precision injection mold for a large sailboat cover of the present embodiment comprises a core plate 1 and a cavity plate 2 with multiple product molding surfaces. The cavity plate 2 is provided with multiple guide posts 21, and the multiple guide posts 21 are respectively provided with plug-in slots 211. The multiple guide posts 21 are not coaxial with the corresponding plug-in slots 211. The core plate 1 is provided with multiple guide slots 11 that can be plugged and matched with the multiple guide posts 21, and the axial cross-sections of the multiple plug-in slots 211 are respectively arranged in polygonal shapes, and the axial cross-sections of the multiple plug-in slots 211 are different. The multiple guide slots 11 are provided with plug-in rods 111 that can be plugged and matched with the plug-in slots 211. When the mold is in the mold-closing state, the multiple guide posts 21 are respectively plugged and matched with the corresponding guide slots 11, and the multiple plug-in rods 111 are respectively plugged and matched with the corresponding plug-in slots 211.

[0032] Reference Figure 1-Figure 4 After the mold is closed, the core plate 1 and the cavity plate 2 are guided during the mold closing process by plugging and matching the multiple guide columns 21 and the corresponding guide grooves 11, and the plugging grooves 211 in the guide columns 21 are plugged and matched with the plugging rods 111 in the guide grooves 11, and the core plate 1 and the cavity plate 2 are positioned after the mold is closed, thereby reducing the possibility of position deviation of the core plate 1 and the cavity plate 2 after the mold is closed, so as to reduce the possibility of different wall thicknesses and groove 51 positions of multiple sailboat covers 5 after injection molding. By making the axial cross-sections of multiple plug slots 211 and plug rods 111 into polygons, the core plate 1 and the cavity plate 2 are guided during the mold closing process, and the core plate 1 and the cavity plate 2 are positioned after the mold closing, thereby reducing the possibility of deterioration of the core plate 1 and the cavity plate 2 after the mold closing. By making the axial cross-sections of the plug slots 211 and the plug rods 111 different, it plays an anti-mistake role and reduces the possibility of the core plate 1 or the cavity plate 2 being in the wrong direction when the mold is installed on the injection molding machine.

A spring 232 is provided in the abutment groove 23. The two ends of the spring 232 abut on the abutment groove 23 and the abutment block 231 respectively. The spring 232 always drives the abutment block 231 to slide toward the side of the core plate 1. When the mold is in the mold closing state, the spring 232 drives the abutment block 231 toward the side of the core plate 1, and makes the guide rod 31 toward the side of the core plate 1, so that the ejector plate 3 fixedly connected to the guide rod 31 moves toward the side away from the core plate 1, so that the ejector plate 3 is reset, reducing the possibility that the ejector plate 3 is not reset to the right position, so as to improve the quality of the finished product.

The cavity plate 2 is provided with an inclusion groove 22 that can cooperate with the plurality of side-drawing blocks 41. When the mold is in a mold-closing state, the plurality of side-drawing blocks 41 are respectively matched with the corresponding inclusion groove 22. Through the cooperation between the side-drawing block 41 and the inclusion groove 22, the side-drawing block 41 after mold closing is positioned, and the possibility of deviation in the position of the side-drawing block 41 after mold closing is reduced, so as to reduce the possibility of deviation in the partial dimensions of the plurality of sailboat covers 5 after injection molding.
