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.

Examples

Referring to fig. 1-2, the electric head mold rotating mechanism provided in this embodiment includes a swing frame 1, a rotating mechanism 2, and a swing frame driving mechanism 3, wherein the swing frame 1 is a U-shaped structure and is formed by fixedly connecting a swing frame bottom plate 11, a swing frame front support plate 12, and a swing frame rear support plate 13. Rotary mechanism 2 includes first steering wheel 21, driving gear 22 and driven gear 23 all are located the top of swing support bottom plate 11, and first steering wheel 21 is located the below of swing support bottom plate 11, head die 10 is fixed on driven gear 23, and fixed mode can adopt the fix with screw, convenient dismantlement, it has the hole to open on the swing support bottom plate 11, can let first steering wheel 21's output be connected with driving gear 22, driving gear 22 and driven gear 23 meshing. The rotating mechanism 2 can drive the head die 10 to rotate left and right.

The single rotating mechanism 2 can only rotate the head die 10 left and right, and cannot rotate the head die 10 at other positions, and therefore, the electric head die rotating mechanism of the present embodiment further includes the swing frame driving mechanism 3. The swing bracket driving mechanism 3 is connected with the swing bracket 1 to drive the swing bracket 1 to swing within a range of (90 degrees to 90 degrees). The swing bracket driving mechanism 3 of the embodiment is implemented by using a second steering engine 30. In order to further realize the connection between the second steering engine 30 and the swing bracket 1, the electric head die rotating mechanism of the embodiment further comprises a first connecting piece 4, the first connecting piece 4 is fixed on the front support plate 12 of the swing bracket, the first connecting piece 4 is provided with a shaft end, the shaft end penetrates through the front support plate 12 of the swing bracket, and the output end of the second steering engine 30 is connected with the shaft end of the first connecting piece 4.

Further, in order to fix and support the swing bracket 1, the rotating mechanism 2, and the swing bracket driving mechanism 3, the electric head die rotating mechanism of the present embodiment further includes a main bracket 5, wherein the main bracket 5 also adopts a U-shaped structure and is formed by fixedly connecting a main bracket bottom plate 51, a main bracket front support plate 52, and a main bracket rear support plate 53. In order to connect the main support 5 and the swing support 1, the electric head die rotating mechanism of the present embodiment further includes a second connecting member 6, the second connecting member 6 is fixed on the swing support rear support plate 13 and also has a shaft end, the shaft end of the first connecting member 4 can penetrate through the main support front support plate 52, and the shaft end of the second connecting member 6 can penetrate through the main support rear support plate 53.
