This utility model provides a mold for flanging one end of the inclined vertical edge of an automobile door sill downwards. It includes an upper mold assembly, a lower mold assembly, and a connecting rod. The upper mold assembly is connected to a stamping device via the connecting rod. The product part is positioned using a locating pin in the lower mold assembly. The product part is fixed and pressed by a clamping mechanism in the upper mold assembly and a lower mold base in the lower mold assembly. During downward movement, the inclined wedge in the upper mold assembly moves to the left due to the force distribution from the inclined surface of the abutment block and the function of the slide rail assembly. The left inclined surface of the inclined wedge contacts the right inclined surface of the flanging upper mold. As the stamping device continues to move downwards, the inclined wedge moves to the lower left under the action of the inclined surface of the right inclined wedge abutment block, pressing the flanging upper mold to move to the lower left. During this movement, the shape of the rear end face of the flanging upper mold acts on the flanging of the product part, completing the flanging with the cooperation of the front end face of the flanging lower mold. This utility model broadens the application range of stamping dies and improves production efficiency.

The application provides a coating liquid system for improving the durability of gold and silver threads and an application thereof, and comprises a foaming type primer liquid used for foaming a coating; a atomizing type transition coating liquid used for atomizing the coating; and a long-acting protection type coating liquid, wherein the long-acting protection type coating liquid at least comprises a compound type high molecular resin emulsion, a mesoporous silica loaded with benzotriazole and an epoxy group modified barium sulfate, and the compound type high molecular resin emulsion is a compound mixed solution of a carboxyl acrylate emulsion, N-hydroxymethyl acrylamide, polyvinyl alcohol and a polyurethane emulsion. The compound mixed solution can solve the protection problem of the exposed cross section after slitting without affecting the size precision, production efficiency and decoration performance of the gold and silver threads.
