Technical Field

[0001] The utility model relates to the technical field of nickel mesh mold connecting die heads, in particular to a novel nickel mesh mold connecting die head device. Background Art

[0002] At present, there are various influencing factors in the production of nickel mesh. Therefore, precision molds are one of the essential main tools in the production of injection molding nickel mesh. The design of precision molds determines the quality of nickel mesh and the yield rate. In other words, whether high-quality and low-cost precision nickel mesh can be processed depends on the mold.

[0003] The existing nickel mesh mold and die head are connected by a screw. This connection structure causes a gap between the mold contact surface diameter and the fit between the screw and the wire sleeve when the mold and the die head are in the high temperature environment of the plating tank. As the wear of the two gradually increases, the torque exceeds the strength limit of the screw, causing the screw to break, thereby reducing the connection strength and service life of the mold and the die head. Utility Model Content

[0006] Further, one side of the first flange is provided with a plurality of positioning slots arranged in a circular array, one side of the second flange is provided with a plurality of positioning pins arranged in a circular array, the plurality of positioning pins are arranged alternately with the plurality of bolt holes, the plurality of positioning slots are arranged alternately with the plurality of bolt holes, and the positioning pins are inserted into the positioning slots.

[0007] Furthermore, the positioning pin is a rectangular column.

[0008] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0009] The utility model has the following beneficial effects:

[0010] When installing the connecting die head at one end of the mold, the first flange connected to the die head and the second flange connected to the mold are docked, and then the first flange and the second flange are connected and fixed by multiple bolt and nut connectors to complete the connection between the mold and the die head. Then, the mold and the die head are connected by the first flange, the second flange and multiple bolt and nut connectors to improve the stability of the mold in the plating tank and the de-gripping frame, ensure the stability and firmness of the connection between the mold and the die head, avoid loosening and falling off of the connection, and improve the service life of the mold and the stability of the connection with the die head.
