Description

Technical Field

[0001] The utility model relates to the technical field of nail receiving mechanisms, in particular to a nail receiving mechanism for nailing and pressing blocks. Background Art

[0002] The in-mold nail embedding device can effectively avoid the positioning accuracy deviation caused by the traditional method of first injecting the mold and then melting the screw, the easy scratching and damage of the plastic parts during turnover, and the labor-consuming problems. It improves the combination accuracy between the screw and the plastic part. The screw and the plastic part are integrally formed, and the joint is not easy to crack, which ensures the product processing quality and saves manpower.

[0003] Patent [CN219405154U] is specifically an in-mold nail embedding device, which positions and supports the screws by setting a nail support mechanism. The nail support mechanism consists of a nail support plate and a nail support column fixedly set on the nail support plate for carrying the screws, that is, one end of the screw with an opening is inverted on the outside of the protrusion set on the top end face of the nail support column, and then the screw is installed inside the mold through a nail embedding mechanism corresponding to the nail support mechanism. However, in this process, the screws are easily separated from the protrusions, resulting in the nail support column and the protrusions set at the nail support column being unable to stably support the screws.

[0004] The main reason for the above problems is that the size of the protrusion on the top end face of the nail column is fixed. When the opening at one end of the screw is a cross or a hexagon, that is, the shape of the screw opening is not equal to the shape of the protrusion, the contact between the protrusion and the screw is incomplete. In addition, for different types of screws, the depth of the opening at one end is also different. When the opening depth at one end of the screw is greater than the height of the protrusion, the contact between the protrusion and the screw is also incomplete. When the nail embedding mechanism moves toward the nail column, it will generate external thrust on the screw, which may easily cause the screw to separate from the nail column under the action of external force. In response to the above problems, we propose a nail bearing mechanism for nailing and pressing blocks. Utility Model Content
