Description

Technical Field

[0001] The present application relates to the field of mold technology, and in particular to a demoulding device for an automobile plate mold. Background Art

[0002] Molds are various molds and tools used in industrial production to obtain the desired products by injection molding, blow molding, extrusion, die casting or forging molding, smelting, stamping and other methods. It mainly realizes the processing of the shape of the object by changing the physical state of the molded material, and is known as the "mother of industry". Molds are widely used in blanking, die forging, cold heading, extrusion, powder metallurgy pressing, pressure casting, and compression molding or injection molding of engineering plastics, rubber, ceramics and other products.

[0003] The existing Chinese patent with announcement number CN206953487U discloses a demoulding device for the rear panel mold of an electric vehicle, which is used for a plastic mold and includes a first ejector pin, a second ejector pin and an inclined ejector pin arranged on one side of the cavity. The inclined ejector pin is in a "V" shape, and includes a first bevel and a second bevel. The first bevel and the second bevel are provided with protrusions on the inner sides of the upper ends, and the surfaces of the protrusions are provided with structures for forming screw hole parts. The outer sides of the first bevel and the outer sides of the second bevel are movably connected to the inner sides of the first ejector pin and the inner sides of the second ejector pin, respectively, and the top ends of the first bevel and the second bevel are flush with the top ends of the first ejector pin and the second ejector pin, respectively. The utility model adopts a structural design in which a "V"-shaped inclined ejector pin is movably connected to the inner sides of two ejector pins, which effectively enhances the driving force for the inclined ejector pin to separate from the product, ensures the smooth completion of demoulding of the screw hole part, avoids the phenomenon of interference between multiple inclined ejectors, and facilitates the demoulding of the screw hole part.

[0004] However, the above-mentioned demoulding device has the following disadvantages: the device is provided with a "V"-shaped inclined ejector to ensure demoulding of the screw hole, but requires strong power during the ejection process of the automobile plate. Insufficient power will lead to incomplete demoulding, which is likely to affect the subsequent processing efficiency. At the same time, after the automobile plate is pressed, the mold cannot be cooled quickly, which is likely to affect the service life of the mold in the long run.

[0005] Therefore, we propose an automobile panel mold demoulding device to solve this problem.
