The top-feeding assembly 22 is located on the outside of the protrusion 21. A lubricating oil supply pipe 211 is provided inside the protrusion 21. Several oil outlets 212 are provided on both sides of the lubricating oil supply pipe 211. A lubricating oil replenishment assembly 3 is provided on one side of the lower die 2. The axis of the oil outlet end of the lubricating oil replenishment assembly 3 is aligned with the axis of the lubricating oil supply pipe 211. The top-feeding assembly 22 includes a mounting rod 221, a top-feeding block 222, and a reset rod 223. One end of the mounting rod 221 and the reset rod 223 are fixedly mounted inside the mounting base plate 20. The other end of the mounting rod 221 and the reset rod 223 are movably connected to the lower end of the top-feeding block 222. A reset spring 224 is movably sleeved on the outside of the other end of the reset rod 223.

[0023] The specific settings and functions of this embodiment are described below. After the upper mold presses down to stamp and shape the raw material on the lower mold 2, the return spring 224 in the ejector assembly 22 releases its elasticity, driving the ejector block 222 to move upward. The ejector block 222 lifts the stamped part, realizing the unloading operation. After multiple unloading operations, the oil outlet in the lubricating oil replenishment assembly 3 extends into the lubricating oil supply pipe 211 and begins to supply lubricating oil. The lubricating oil flows out from the oil outlet 212, lubricating the gap between the protrusion 21 and the ejector block 222, avoiding jamming between the protrusion 21 and the ejector block 222 due to lack of lubricating oil, and improving the stability and smoothness of normal demolding of the mold.

[0024] Example 2: Figure 1 - Figure 4 As shown, the appliance base beam forming mold of this utility model includes a mounting base 1. A lower mold 2 is fixedly mounted on the upper end of the mounting base 1. The lower mold 2 includes a mounting base plate 20, a protrusion 21, and a top-ejector assembly 22. The top-ejector assembly 22 is located on the outside of the protrusion 21. A lubricating oil supply pipe 211 is provided inside the protrusion 21. Several oil outlets 212 are respectively provided on both sides of the lubricating oil supply pipe 211. A lubricating oil replenishment assembly 3 is provided on one side of the lower mold 2. The axis of the oil outlet end of the lubricating oil replenishment assembly 3 is aligned with the axis of the lubricating oil supply pipe 211. The linear lubricating oil replenishment assembly 3 includes an adjustment frame 31, a dual-pipe oil supply unit 32, and an electric telescopic rod. The dual-pipe oil supply unit 32 is slidably connected to one side of the adjustment frame 31, and the drive end of the electric telescopic rod is fixedly connected to one side of the dual-pipe oil supply unit 32.

The slide rail 324 is fixedly installed on one side of the adjustment frame 31.

[0025] The overall effect of this embodiment is that after the oil supply is completed, the electric telescopic rod resets and drives the dual-pipe oiler 32 to move away from the lower mold 2. The oil supply pipe 321 in the dual-pipe oiler 32 slides out from the inside of the lubricating oil supply pipe 211, without affecting the subsequent stamping operation. Furthermore, the lubricating oil replenishment component 3 is set on the outside of the mold, reducing the difficulty of mold production and facilitating the daily maintenance and cleaning of the lubricating oil replenishment component 3.

[0026] The usage and working principle of this device are as follows: After the upper mold presses down to stamp and shape the raw material on the lower mold 2, the return spring 224 in the ejector assembly 22 releases its elasticity, driving the ejector block 222 to move upward. The ejector block 222 lifts the stamped part, realizing the unloading operation. After multiple unloading operations, the oil outlet in the lubricating oil replenishment assembly 3 extends into the lubricating oil supply pipe 211 and begins to supply lubricating oil. The lubricating oil flows out from the oil outlet 212, lubricating the gap between the protrusion 21 and the ejector block 222. After the oil supply is completed, the electric telescopic rod resets, driving the double-pipe oil supply device 32 to move away from the lower mold 2. The oil supply pipe 321 in the double-pipe oil supply device 32 slides out from the inside of the lubricating oil supply pipe 211.

[0027] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
