Description

Technical Field

[0001] The utility model relates to the field of molds, in particular to a clip nut riveting forming 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. In short, molds are tools used to make molded objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the object by changing the physical state of the molded material. It is known as the "mother of industry".

[0003] In the prior art, clip nuts are generally divided into one-piece clip nuts and combined clip nuts. The one-piece clip nuts can be directly processed and formed by a mold, while the combined clip nuts are composed of a clip and a nut.

[0023] First, insert the positioning block 15 installed on the bottom surface of the side mold 14 into the positioning groove 13 opened on the right side of the top surface of the L-shaped bottom mold 10, so that the side mold 14 is positioned and installed on the right side of the top surface of the L-shaped bottom mold 10, and the bottom surface of the semicircular concave mold cavity 12 and the semicircular concave mold cavity 12 on the right side of the top surface of the L-shaped bottom mold 10 are combined to form a circular cavity hole. Then, the U-shaped clip 20 that has completed the punching process and has not been formed is placed on the top surface of the L-shaped bottom mold 10, and the first hydraulic cylinder 5 installed on the top surface of the shell 1 is turned on. The first hydraulic cylinder 5 will drive the output end to drive the T-shaped upper die 6 to move downward, and the rear end wall of the lateral part of the T-shaped upper die 6 is installed The first slider 7 installed will slide in the first slide groove 3 opened on the inner rear end wall of the shell 1. When the vertical part of the T-shaped upper die 6 is pressed down to the top surface of the plate-like member, the plate-like member will enter the U-shaped die groove 11 opened on the top surface of the L-shaped bottom die 10 after being squeezed, and will be pressed into a U-shaped U-shaped clip 20 under the action of the vertical part of the T-shaped upper die 6. Subsequently, the nut 22 for riveting connection is placed from the right side of the L-shaped bottom die 10 into the cavity hole formed by the bottom surface of the side die 14 and the semicircular concave die cavity 12 opened on the right side of the bottom surface of the L-shaped bottom die 10. Then, the second hydraulic cylinder 16 installed on the right side wall of the shell 1 is turned on, and the second The hydraulic cylinder 16 will push the movable plate 17 to move to the left on the inner bottom surface of the housing 1, and the second slider 18 installed on the bottom surface of the movable plate 17 will slide in the second slide groove 4 opened on the inner bottom surface of the housing 1 during the movement, until the riveting column 19 installed on the left side wall of the movable plate 17 enters the cavity hole and squeezes the nut 22 inside, so that the riveting part on the left side of the nut 22 passes through the reserved hole opened on the U-shaped clip 20, and after being squeezed to a certain extent, the riveting part on the left side of the nut 22 will be resisted by the stop block 9 installed in the groove 8 opened on the right side of the T-shaped upper die 6. At this time, under the continuous squeezing force, the riveting part on the left side of the nut 22 will The nut 22 is deformed and embedded into the embedding groove 21 on the right side of the nut 22, so that the nut 22 can be riveted and fixed on the U-shaped clip 20. Finally, the first hydraulic cylinder 5 and the second hydraulic cylinder 16 are started again to drive the T-shaped upper die 6 and the movable plate 17 back to their original positions, and then the side die 14 is removed from the top surface of the L-shaped bottom die 10, and then the formed clip nut can be taken out. Therefore, the clip nut can be formed in one time by the riveting forming mechanism 2 using the pressing and riveting connection method, and there is no need to fix the nut 22 on the U-shaped clip 20 by welding. The operation is simple and convenient, and the processing efficiency of the combined clip nut is improved.
