AI Technical Summary
In the pre-embedded injection molding process, the embossed nut is prone to slide on the mold insert, resulting in a gap with the rubber surface. After the injection molding is completed, the central hole is blocked and the bolt cannot be inserted, resulting in product scrapping.
Design a copper nut with a figure-shaped piece of copper, with hexagonal flange, threaded hole and annular cushion slot on the nut body, and there are convex rings and twills on the outside. By setting the ring-shaped cushion slot and the side telescopic part of the insert in the threaded hole, the fixing nut is ensured. Its position is stable, and a convex ring is provided on the outside to enhance the resistance to torsion and tensile.
It effectively avoids the movement of the nut during the mold clamping process, improves the yield of the injection molded products, ensures smooth connection of the screw, and improves the stability and quality of the product.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fasteners, in particular to an eight-shaped copper nut. Background Art
[0002] Embedded injection molding is a process that first places the embossed nut on the mold pin and then performs injection molding. After the injection molding is completed, the embossed nut is fully wrapped by plastic to achieve the matching of the embossed nut and the product. However, when the mold is moved and closed, the embossed nut is easy to slide on the pin, causing a gap between the embossed nut and the rubber surface. After the injection molding is completed, the center hole of the embossed nut is blocked by plastic and the bolt cannot be inserted, causing the injection molded product to be scrapped.
[0003] Based on the above technical problems, the present application proposes an eight-shaped copper nut. Utility Model Content
[0004] The purpose of the utility model is to provide a copper nut with an eight-shaped pattern to solve the technical problems mentioned in the background technology. The purpose of the utility model is achieved through the following technical solutions:
[0005] The utility model discloses an eight-shaped copper nut, comprising a nut body, one end of which is provided with a hexagonal flange, a threaded hole is penetrated through the inner center of the nut body, an annular groove is provided in the threaded hole, and the annular groove is located at one end close to the hexagonal flange.
[0006] Furthermore, a convex ring is arranged on the outer side of the nut body, and a diagonal pattern is arranged on the outer side of the convex ring.
[0007] Furthermore, the convex ring includes a first convex ring and a second convex ring, the first convex ring and the second convex ring are arranged at an interval, the first convex ring is provided with a first twill, the second convex ring is provided with a second twill, and the first twill and the second twill are distributed in an eight-shaped shape.
[0008] Furthermore, a third convex ring is arranged on the outer side of the nut body, the third convex ring is located at one end of the nut body away from the hexagonal flange, and the third convex ring is conical.
[0009] Furthermore, there are at least two third protruding rings.
[0010] The technical solution provided in the embodiments of the present application has at least the following technical effects or advantages:
[0011] An annular groove is provided in the threaded hole, and the nut is fixed by engaging the telescopic part on the side of the insert pin with the annular groove, thereby preventing the nut from moving during the mold closing process and not affecting the connection of the screw, thereby improving the yield rate of the injection molded product. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the drawings and specific implementation methods of the specification. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0017] like Figure 1 , Figure 2 The illustrated eight-shaped copper nut comprises a nut body 1, which is a cylindrical structure, and a hexagonal flange 2 is fixed to the upper end of the nut body 1, and the hexagonal flange 2 and the nut body 1 are an integral structure. A threaded hole 3 is formed through the inner center of the nut body 1, and an annular groove 31 is formed on the hole wall of the threaded hole 3, and the annular groove 31 is located at one end of the threaded hole 3 close to the hexagonal flange 2.
[0018] By setting an annular groove 31 in the threaded hole 3, a retractable telescopic part (such as a ball head telescopic pin, etc.) can be installed on the side of the insert pin and engage with the annular groove 31 to achieve fixation of the nut and the insert pin, while not affecting the bolt from being screwed into the threaded hole 3.
[0019] like Figure 1 , Figure 2As shown, the outer side of the nut body 1 is integrally formed with a first convex ring 4 and a second convex ring 5, and the first convex ring 4 and the second convex ring 5 are arranged at intervals, so that plastic can flow between the first convex ring 4 and the second convex ring 5 during injection molding, thereby increasing the stability of the connection between the nut body 1 and the injection molded product. Among them, the first convex ring 4 is pressed with a first twill 41, and the second convex ring 5 is pressed with a second twill 51, and the first twill 41 and the second twill 51 are distributed in an eight-shaped shape, thereby improving the torsion and tensile resistance of the nut body 1.
[0020] like Figure 1 , Figure 2 As shown, two third convex rings 6 are integrally formed on the outer side of the nut body 1, and the third convex rings 6 are located at the bottom end of the nut body 1. The third convex rings 6 are inverted cones, and the conical surface of the third convex rings 6 is 60° with the axis of the nut body 1. The provision of the third convex rings 6 can further improve the tensile performance of the nut body 1.
[0021] In the description of the present utility model, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present utility model and simplifying the description. Unless otherwise stated, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction.
