Through the above scheme, after the hinge processing is completed, automatic unloading can be achieved, which is convenient for processing and use. It can be understood that the above scheme can realize automatic unloading after the hinge processing is completed.

[0021] In this embodiment, the bottom plate 101 is used to install and fix the mold.

[0022] Among them, the fixed mold 102 is fixedly connected to the base plate 101 and is located on the base plate 101, the movable mold 103 cooperates with the fixed mold 102 and is located above the fixed mold 102, a guide groove 107 is provided on the movable mold 103, the mounting plate 104 is fixedly connected to the movable mold 103 and is located on the side of the movable mold 103 away from the fixed mold 102, the cylinder 105 is fixedly connected to the mounting plate 104 and is located on the mounting plate 104, the moving block 106 is slidably matched with the movable mold 103, and is connected to the output end of the cylinder 105, and is located at the lower left side of the movable mold 103, and the mounting assembly is arranged on both sides of the upper left side of the movable mold 103. The fixed mold 102 is mounted on the base plate 101 by bolts, and the bolts are installed from bottom to top and are countersunk. A molding cavity is arranged on the fixed mold 102, and the working part on the movable mold 103 can cooperate with the molding cavity. A guide groove 107 is arranged on the movable mold 103 to facilitate the sliding of the guide sliding part of the movable block 106. The semicircular inner curved surface on the movable block 106 can be slidably matched with the working part of the movable mold 103. The mounting plate 104 is mounted on the movable mold 103 by locating pins and bolts. The cylinder 105 is mounted on the mounting plate 104 by bolts. The connecting part at the bottom of the movable block 106 is mounted on the output end of the cylinder 105 by bolts, and the bolts are countersunk.
