[0018] In order to make the technical means, creative features, objectives and functions achieved by the present invention clearer and easier to understand, the technical solutions in the present invention are further described below with reference to the accompanying drawings and embodiments.
[0019] See also Figures 1 to 3As shown, a refrigerator hinge stamping die comprises: a base 1, a lower die 2, a column 3, a horizontal plate 4, a hydraulic cylinder 5 and an upper die 6; the lower die 2 is fixed on the base 1, and columns 3 are vertically provided at both ends of the upper surface of the base 1, and a horizontal plate 4 is connected between the top ends of the two columns 3. The hydraulic cylinder 5 is arranged on the horizontal plate 4, and the hydraulic rod of the hydraulic cylinder 5 is downwardly connected to the upper die 6, and a discharge port 21 is provided at both ends of the lower die 2, and a side groove is provided at both ends of the base 1, and a connecting port 11 connected to the discharge port 21 is provided above the side groove, and a collection box 7 with an upper opening is provided in the side groove, and a handle 71 is provided on the upper part of one end of the collection box 7, and a protruding plate 72 is provided at the lower part, and a fixing rod 8 for fixing the protruding plate 72 is provided on the side wall of the base 1.
[0020] A tool for trimming is provided on the upper mold 6, and its structure can be set with reference to the existing technology. The tool is not drawn in the figure. The hydraulic cylinder 5 drives the upper mold 6 to move downward, and a discharge port 21 is provided on the lower mold 2, and a collection box 7 is provided on the base 1. A connecting port 11 is also provided on the base 1, so that the waste after cutting falls from the discharge port 21 and enters the collection box 7 through the connecting port 11 for collection, which is convenient for centralized processing and does not require workers to clear them one by one, saving time and effort.
[0021] Furthermore, if Figure 2 and Figure 3 The figure shows the specific configuration of the fixing rod 8. The side wall of the base 1 is provided with a fixing block 9, which has a cavity 91 therein.
