Detailed Description

The technical solution of the present invention will be described clearly and completely with reference to the accompanying drawings, and obviously, the described embodiments are some, but not all embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

Furthermore, the technical features mentioned in the different embodiments of the invention described below can be combined with each other as long as they do not conflict with each other.

As shown in FIG. 1, the outer end faces of the seven convex columns indicated by A in the figure have flatness requirements. It is difficult to meet the required requirements by the traditional processing technology and design scheme, and the mass production in the later period is unstable. There is therefore a need for a mold capable of adjusting flatness.

As shown in fig. 2, the mold enables flatness adjustment. A mould cavity 2 is arranged in the mould. The cavity 2 is provided with a plurality of die holes 1 (positions indicated by circles B).

As shown in fig. 3, fig. 3 is an enlarged view at B in fig. 2. The die orifice 1 extends inwardly from the bottom surface of the die cavity 2. The die holes 1 correspond to the studs indicated by a in fig. 1, i.e. the studs indicated by a in fig. 1 are formed in the die holes 1. The die hole 1 is provided with an internal thread (not shown) through which a rotary body 3 is coupled.

As shown in fig. 4, the rotary bodies 3 are disposed in the die holes 1 shown in fig. 3, and the rotary bodies 3 are disposed in one-to-one correspondence with the die holes 1. The outer periphery of the rotary body 3 is provided with an external thread 32. The external thread 32 is combined with the internal thread in the die hole 1 so that the position of the screw body 3 can be adjusted when the screw body 3 is rotated.

The part of the rotary body 3 facing the cavity 2 is provided with an adjusting plane 31, and the adjusting plane 31 corresponds to the outer end surface of the convex column indicated by a in fig. 1. Thus, when it is found that the flatness of the outer end surface of the stud shown in a in fig. 1 is not satisfactory, the flatness can be adjusted by adjusting the position of the rotary body 3.

As shown in fig. 4, the rotating body 3 is further provided with a wrench butt-joint hole 33 which is a hexagon socket, and the wrench butt-joint hole 33 is used for butt-joint with a wrench, so that the rotating body 3 can be conveniently rotated by the wrench.

The rotary body 3 is also provided with a positioning rod 34, and the positioning rod 34 can be used for being inserted with an embedded part which is preset to be embedded into an injection molding product, so that the position of the embedded part can be more accurately positioned.

As shown in fig. 1 and 3, a runner 4 is connected between the die holes 1, and ribs are formed in the runner 4, so that the strength of the product can be enhanced.

In summary, the matching between the mold hole 1 and the rotary body 3 makes it possible to adjust the position of the adjustment plane 31 by rotating the rotary body 3 when the product is molded and if the flatness of the outer end surfaces of the plurality of protruding columns on the product does not meet the requirement, so that the flatness of the outer end surfaces of the protruding columns in the injection molding product meets the requirement.

The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and to implement the present invention, so as not to limit the protection scope of the present invention, and all equivalent changes or modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
