Technical Field

[0001] The present invention relates to the technical field related to hinge molding, and in particular to a lightweight hinge integrated molding device and a molding process. Background Art

[0002] A hinge, also known as a hinge, is a mechanical device used to connect two solids and allow relative rotation between them. A hinge can be composed of movable components or foldable materials. Hinges are mainly installed on doors and windows, while hinges are more often installed on cabinets. They are mainly divided into stainless steel hinges and iron hinges according to the material classification. When producing lightweight hinges, integrated molding equipment is required for auxiliary processing.

[0003] There are many types of existing integrated molding equipment, but there are still certain shortcomings in operation. During production, the raw materials are molded by stamping, but the efficiency is low during use. In order to solve the above-mentioned defects, reference can be made to a hinge stamping and curling molding device disclosed in the prior art (application number CN202322000551.5, Chinese patent published on 2024-01-26). The molding device enables the first stamping seat and the second stamping seat to be stamped simultaneously through a stamping platform, making the overall structure of the equipment simpler; at the same time, it also simplifies the operation. Two processes can be completed by operating the stamping platform once, thereby speeding up its work efficiency. At the same time, reference can also be made to a hinge molding device disclosed in the prior art (application number CN201921207173.5, Chinese patent published on 2020-05-08). The molding device places one end of the hinge to be pre-bent on the V-groove, moves the upper die seat downward, and allows the extrusion die to extrude Hinge, bend the hinge; after the pre-bending is completed, put the hinge into the forming mold for forming, and the end of the hinge away from the forming mold is clamped by the auxiliary plate; the hinge can be quickly pre-bent using the above-mentioned hinge forming device, and the structure is simple and the operation is convenient. It is suitable for hinges of different lengths and diameters. Compared with the traditional manual forming method, the production efficiency is higher; and a kind of automobile hinge stamping die and the automobile hinge disclosed in the prior art (application number CN202420321539.6, Chinese patent with publication date of 2024-10-01) can be referred to. The stamping die presses the hinge body through the forming bottom plate, and the forming bottom plate is convenient to slide in the limiting groove through the limiting block, the mounting plate is supported by the telescopic rod, the clamping assembly is installed through the mounting plate, the mounting plate is buffered by the buffer spring, and the pressure detector is installed through the mounting base. The pressure on the mounting plate is detected by the pressure detector, thereby effectively preventing damage to the forming plate and the hinge.

The knocking block 83 forms a knocking structure with the convex block of the vibration block 9 through the rotation of the rotating rod 81; the demoulding mechanism includes a movable horizontal plate 11 fixed to the bottom of the threaded connector 10, and a wedge block 12 is also fixed to the front end of the movable horizontal plate 11. The inclined surface of the wedge block 12 fits the bottom inclined surface of the matching block 13. The top of the matching block 13 is fixed with a push rod 14. The top of the push rod 14 slides inside the stamping fixed mold 4. The bottom of the matching block 13 is fixed with The guide rod 15, the bottom of the guide rod 15 is slidably set inside the fixed cylinder 17 through the connecting spring 16; the movable cross plate 11 is slidably set inside the forming frame 1, and the matching block 13 forms a sliding structure with the inside of the forming frame 1 through the movement of the wedge block 12; the wedge block 12, the matching block 13, the push rod 14, the guide rod 15, the connecting spring 16 and the fixed cylinder 17 are symmetrically distributed in two groups about the vertical center line of the movable cross plate 11, and the bottom outer side of the fixed cylinder 17 is fixed inside the forming frame 1.
