Novel carriage hinge and mold and method for manufacturing novel carriage hinge

Abstract

The invention provides a novel carriage hinge. The novel carriage hinge comprises an upper hinge and a lower hinge, wherein the upper hinge is in an inner coiling ear structure which is molded integrally by steel plates in a cold coiling mode; the upper hinge and the lower hinge are connected by a pin shaft arranged in a through hole and a coiling ear hole in a penetrating manner. A mold for manufacturing the novel carriage hinge comprises a rib reinforcement mold, a molding mold and a cylindrical mold core. A method for manufacturing the novel carriage hinge comprises the following steps: (1) compressing a reinforcement rib and molding a coiling ear hole part in the side of an inner side plate; (2) molding the coiling ear hole; (3) molding a supporting plate; (4) shearing; and (5) welding. The novel carriage hinge has the advantages of scientific design, capability of releasing the internal width of a carriage and simple and firm structure. The mold for manufacturing the novel carriage hinge has the advantages of simple structure and convenience and accuracy in molding; the method for manufacturing the novel carriage hinge has the advantages of being reasonable in steps and efficient to operate.

Description

technical field [0001] The present invention relates to a hinge, in particular to a new compartment hinge, and also relates to a mold for making the hinge and a method for making the hinge. Background technique [0002] With the development of the logistics industry, more and more attention has been paid to efficient logistics. Many goods are directly loaded on pallets, which is convenient for forklifts to load and unload goods, saving a lot of time. However, the conventional size of the pallet is between 1.1m and 1.2m, and for a semi-trailer with a normal external width of 2500mm, because the installation of the baffles on both sides is affected by the traditional hinge structure, the width of the inner control box is actually between 2310mm and 2330mm During the period, it is usually encountered that two pallets cannot be placed side by side, which greatly affects the efficiency of loading and unloading goods, and the scope of application is greatly reduced.
