Description
Technical Field
The utility model relates to a painting mould, especially a self-centering painting mould of high degree of freedom.
Background
In order to improve the painting uniformity of the enameled wire, the enameled wire is painted by adopting a painting mold at present, when the enameled wire is used, paint is coated on the surface of a copper wire through a painting roller, then the copper wire coated with a paint film passes through the painting mold, and redundant paint on the surface of the copper wire is removed by the painting mold, so that the thickness of the paint film on the surface of the copper wire is controlled. However, because there are some angles between the guide rollers on both sides of the painting mold, and the enameled wire can also form multi-directional jumping in the wire routing process, the mold core also needs to have a self-centering function, i.e. the mold can swing freely along with the change of the wire routing direction of the enameled wire, thereby preventing the enameled wire from passing through the mold core at a bent angle and causing the reduction of the uniformity of the paint film.
In order to achieve the effect, the conventional mold core consists of a suspended mold core and a fixed baffle, the middle part of the baffle is provided with a strip hole for the enameled wire to pass through, the mold core is suspended in the air and can freely lift and translate along with the enameled wire when in use, and the baffle blocks one side of the mold core, so that the mold core is prevented from moving in the wire routing direction due to the impact force of the enameled wire. When the mold core is applied to an enameled wire with paint viscosity lower than 1000mPas, the required self-positioning effect can be achieved, but with the increase of the paint viscosity, the impact force exerted on the mold core by the enameled wire when the enameled wire passes through the mold core is gradually increased; when the viscosity of the paint reaches more than 5000mPas, the mold core can be tightly attached to the baffle under the action of impact force and forms larger frictional resistance, so that the tension force generated by the enameled wire after bending is not enough to drive the mold core to move horizontally, and the self-positioning function of the mold fails.
On the other hand, the baffle needs to play a stable blocking function for the mold core when in use, so that the width of the strip hole on the baffle is not too large, and the problem that the mold core penetrates through the strip hole and moves axially due to the fact that the position of the mold core is lost when the mold core moves to the extreme position is solved. The structure enables the mold core to realize a unidirectional self-positioning function only, and the other direction is limited by the width of the long hole and only has a small moving space; thereby further reducing the self-positioning effect of the enameled wire and intensifying the bending or abrasion of the enameled wire.
Therefore, the existing self-positioning mold core for the enameled wire has the problems of poor automatic positioning effect and easy clamping stagnation of the mold core.
