The present disclosure will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
Fig. 1 is a schematic structural view of some embodiments of a cylindrical article including a circular arc structure of the present disclosure. Fig. 1 includes a first segment 11, a second segment 12, a third segment 13, and a circular arc chamfer 14.
Fig. 2 is a cross-sectional view of the cylindrical article including the circular arc structure shown in fig. 1 at A-A'.

Wherein the first section may be located at one end of the cylindrical article including the circular arc structure. The left end of the cylindrical article comprising a circular arc structure as shown in fig. 1. The second section may be located at the other end of the cylindrical article including the circular arc structure. For example, the right end of a cylindrical article including a circular arc structure as shown in fig. 1. The outer diameter dimensions and the length of the first section and the second section are not limited.
Alternatively, the outer diameter dimensions of the first and second sections may be the same. Wherein the outer diameter of the first and second sections may range from 6.62 to 6.82 millimeters. For example, the outer diameter is 6.72 mm and the tolerance requirement may be + -0.1 mm.
Alternatively, the lengths of the first and second sections may be the same. Wherein the length of the first section and the second section may range from 9.5 to 10.5 mm. For example, a length of 10 mm, the tolerance requirement may be + -0.1 mm.
In some embodiments, the third section may be located intermediate the first section and the second section. The third section and the first section may be transitioned by a circular arc chamfer 14. The third section and the second section may be transitioned by a circular arc chamfer 14. Here, the dimensions of the circular arc chamfer are not limited. Therefore, the cylindrical article can be conveniently fixed inside the structure, and the stability of the cylindrical article inside the structure is improved.
Alternatively, the radius of the circular arc chamfer may be 0.36 mm.
Optionally, the outer diameter of each of the first section and the second section may be larger than the outer diameter of the third section. For example, the outside diameter of the third section may range from 5.95 to 6.05 millimeters. Wherein the outer diameter is 6 mm and the tolerance requirement can be + -0.05 mm. Therefore, the cylindrical object can be fixed inside the structure on the outer side face of the third section, limiting and fixing can be performed through the arc structure, and the stability of the cylindrical object inside the structure is improved.
In some embodiments, the first section, the second section, and the third section may be injection molded in one piece by a cavity insert in a mold. The cavity insert may be an insert of an article cavity. The cavity insert may comprise at least one article cavity. The shape of the cavity insert is not limited. For example, the cavity insert may have a square or cylindrical shape. The article cavity may be a cavity for filling a plastic melt injected by an injection molding machine to injection mold a cylindrical article comprising a circular arc structure. The shape of the article cavity is the same as the shape of the article. The number of article cavities that the cavity insert may include is not limited. For example, the cavity insert may include 4 article cavities. Therefore, when the circular arc structure of the cylindrical article is injection molded, the cylindrical article can be molded in one step through the article cavity, and demolding is not required through the sliding block mechanism, so that the mold structure and the manufacturing process are simplified.
Alternatively, the length of the cylindrical article including the circular arc structure may range from 31 to 32 mm. For example, the length may be 31.5 millimeters and the tolerance requirement may be + -0.5 millimeters.
Alternatively, the cylindrical article including the circular arc structure may include a through hole. The through hole may be a through hole penetrating both ends of the cylindrical article including the circular arc structure. The shape of the through hole is not limited. For example, the through hole may be a square through hole. Thereby, the cylindrical article may also be provided as a connection in the interior of the structure.
Alternatively, the through hole may be a cylindrical through hole penetrating through both ends of the cylindrical article including the circular arc structure. Wherein the diameter of the through hole ranges from 3.25 to 3.45 mm. For example, a diameter of 3.35 mm, the tolerance may be + -0.1 mm.
In order to meet the use requirement, the production process also needs to make technological requirements on the central shafts of the two. The coaxiality error of the through hole and the outer cylindrical surface of the cylindrical object comprising the circular arc structure can be 0.1 millimeter.
When the cylindrical article including the circular arc structure includes the through hole, the cylindrical article including the through hole and the circular arc structure may be injection molded once by being engaged with the article cavity in the mold through the cavity insert pin in the production process. Wherein the shape and size of the cavity insert pin are the same as the shape and size of the through hole. One end of the cavity needle can be arranged in the article cavity, and the other end of the cavity needle is fixed on the rear die plate. Therefore, when the cylindrical article comprising the circular arc structure comprises the through hole, the slide block mechanism is not needed for core pulling, so that the die structure and the manufacturing process can be simplified.
