Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, specifically to an ejector structure for sheet metal processing. Background Technology

[0002] Sheet metal processing is a metal processing technology mainly used to produce various sheet metal products. It usually refers to parts or products made by processing thin metal sheets through cold working methods (such as shearing, stamping, bending, welding, etc.). Common sheet metal materials include carbon steel, stainless steel, galvanized steel, aluminum sheet, etc.

[0003] Stamping refers to the process of using stamping equipment and dies to plastically deform or separate sheet metal under pressure, thereby obtaining parts with specific shapes, dimensions, and properties. It is widely used in industries such as automobiles, home appliances, and electronics. After stamping, the sheet metal parts deform and come into close contact with the die, making demolding difficult. Existing technologies incorporate an ejector structure to push the sheet metal parts upwards from the bottom of the lower die. However, in practical use, because the sheet metal parts are in close contact with the die, the forced ejection process may cause wear on the inner surface of the lower die. This wear will further increase the difficulty of demolding, indicating room for technological improvement. Utility Model Content

[0004] This invention aims to solve the aforementioned technical problem that the inner surface of the lower mold may be worn during the forced ejection process, and provides an ejection structure for sheet metal processing.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: an ejection structure for sheet metal processing, including an operating table, the operating table being hollow inside, a detachable lower mold being provided on the operating table, the base plate of the lower mold being movable up and down; an L-shaped mounting frame with a longitudinal section is provided on the upper part of the operating table and near the rear end, and an upper mold is movable below the mounting frame; further comprising:

[0006] Auxiliary release component one; located in front of the operating table, including a coolant tank; the left and right sides of the coolant tank are respectively connected to an outlet pipe and an inlet pipe that can communicate with the operating table; the coolant tank is equipped with a pump connected to the inlet pipe;

[0007] Auxiliary release component two; located in front of the operating table, including a release agent tank; a hollow rod is rotatably provided at the upper end of the release agent tank, and a nozzle is provided at the end of the hollow rod away from the release agent tank; a hose is provided inside the release agent tank, one end of the hose is connected to pump two, and the other end is connected to the nozzle.

[0008] Furthermore, the operating table is provided with a mounting groove, which can accommodate the lower end of the mold. The lower mold is installed on the mounting groove by bolts. The mounting groove is provided with a number of electric push rods, and the output end of the electric push rods contacts the bottom surface of the lower mold.

[0009] Furthermore, the operating table is equipped with a cylinder, the output end of which extends to the bottom of the mounting frame and is connected to the upper mold.

[0010] Furthermore, a base plate is provided under the operating table.

[0011] Furthermore, the upper end of the release agent box is provided with a circular groove, and a bearing that can be connected to the hollow rod is provided in the circular groove.

[0012] Furthermore, both the coolant tank and the mold release agent tank are equipped with liquid inlets.

[0013] The advantages of this utility model compared with the prior art are as follows:

[0014] The operating platform used for installing the lower mold is hollow inside and can circulate coolant to cool the lower mold, thereby reducing the heat generated by the sheet metal parts due to high-speed impact and friction. The cooling also reduces the friction between the sheet metal parts and the inner side of the lower mold, thus reducing the impact on the inner side of the lower mold during subsequent removal.

[0015] Before stamping, a release agent can be sprayed onto the inner side of the lower die to further reduce the frictional contact between the sheet metal part and the lower die after deformation, making it easier to eject. Attached Figure Description

When it is removed, the bottom plate of the lower mold 2 can be pushed upward by the operation of the electric push rod 13. It is worth mentioning that the lower side of the lower mold 2 is designed with an L-shaped longitudinal section, which limits the bottom plate of the lower mold 2 and prevents it from falling.
