[0026] like Figures 1-4 As shown, electric push rods 10 are fixedly installed on both sides of the stamping table 1. The transmission end of the electric push rod 10 extends into the interior of the placement groove 2. A snap-fit ​​plate 11 is fixedly installed on the transmission end of the electric push rod 10. The snap-fit ​​plate 11 is adapted to the snap-fit ​​groove 4 and is movably connected to the snap-fit ​​groove 4. Support guide rods 12 are fixedly installed at the four corners of the top of the stamping table 1. A slider 13 is movably installed on the outer end of the support guide rod 12. The slider 13 is located at the four corners of the connecting plate 5 and is fixedly connected to the connecting plate 5. A top plate 14 is fixedly installed on the top of the support guide rod 12. A hydraulic cylinder 15 is fixedly installed on the top of the top plate 14. The transmission end of the hydraulic cylinder 15 extends... At the bottom of the top plate 14, the transmission end of the hydraulic cylinder 15 is fixedly connected to the connecting plate 5. Bolts 16 are movably installed on both sides of the connecting plate 8. The bolts 16 extend to the inner end of the connecting slide rod 6. Several demolding rods 17 are evenly fixedly installed at the bottom of the lower mold 3. A demolding template 18 is fixedly installed at the top of the demolding rod 17. The demolding template 18 is movably connected to the inner wall of the lower mold 3. A water channel 19 is opened on one side of the placement groove 2.

[0027] Working principle: First, when producing refrigerator sheet metal parts, the operator can change the appropriate lower mold 3 and upper mold 7 according to the refrigerator model. The lower mold 3 is placed in the placement slot 2 of the stamping table 1. The electric push rod 10 pushes the snap-fit ​​plate 11 into the snap-fit ​​slots 4 on both sides of the lower mold 3 to clamp and fix it. The connecting groove 9 of the connecting plate 8 on the upper mold 7 is aligned with the connecting slide rod 6. Then, the bolts 16 are used to fix the connection. After installation, the operator puts the material into the lower mold 3, and the hydraulic cylinder 15 pushes... The moving connecting plate 5 and the upper mold 7 move down to stamp the sheet metal material. During the stamping process, the stability of the moving connecting plate 5 and the upper mold 7 is ensured by the action of the slider 13 and the support guide rod 12, avoiding the problem of mold offset during the stamping process. After the stamping is completed, the extrusion pressure disappears. Under the action of the demolding rod 17 and the demolding plate 18, the demolding can be assisted to push out the sheet metal part. When cleaning the stamping table 1 later, the wastewater from the cleaning flows into the water collection tank 22 through the water channel 19 and the water collection frame 20, which facilitates the collection of wastewater.
