[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-3 The present embodiment provides a technical solution: a lacquer porcelain jewelry mold, comprising a fixed frame 2, a roller frame 3 is arranged on the outer side of the fixed frame 2, a bottom mold 6 is arranged on the inner side of the fixed frame 2, a lower ball groove 7 is arranged on the bottom mold 6, an upper mold 5 is arranged on the upper side of the bottom mold 6, an upper ball groove 9 is arranged on the lower side of the upper mold 5, a central axis 11 is arranged at the center of the inner side of the upper ball groove 9, an electric push rod 12 is arranged on the lower side of the bottom mold 6, a rotating shaft 14 is arranged on the outer side of the bottom mold 6, and a connecting plate 4 is welded on one side of the roller frame 3.

[0020] like Figure 1-3As shown, the rotating shaft 14 causes the bottom mold 6 to rotate around the fixed frame 2, and then the electric push rod 12 pushes the bottom mold 6 to flip upward, so that the spherical ceramic body in the lower ball groove 7 is easy to demold, and the central axis 11 can penetrate the inside of the spherical ceramic body to form a through hole, which is convenient for the production of lacquer porcelain bracelet balls, simplifies the production steps, and improves production efficiency.

[0021] A cylinder fixing plate 8 is arranged at the center of the upper side surface of the upper mold 5 , and a rubber wheel 13 is arranged on the inner side of the roller frame 3 .

[0022] like Figure 1-3 As shown, the cylinder fixing plate 8 is convenient for fixing the upper mold 5 and the cylinder, so that the cylinder can push the upper mold 5 to move up and down, and the rubber wheel 13 can make the fixing frame 2 move along the guide rail 1, so that the fixing frame 2 and the bottom mold 6 move to the lower side of the upper mold 5, so as to facilitate extrusion to form the lacquer porcelain bracelet ball.

[0023] Limiting protrusions 10 are arranged at the four corners of the upper side of the fixing frame 2 , and a guide rail 1 is arranged at the lower side of the rubber wheel 13 .

[0024] like Figure 1-3 As shown, the limiting protrusion 10 can limit the closing of the upper mold 5 to ensure that the upper mold 5 and the bottom mold 6 are closed accurately and the mold quality is guaranteed.

[0025] The roller frame 3 is welded to the fixing frame 2, the bottom mold 6 is connected to the fixing frame 2 via a rotating shaft 14, and the lower end of the electric push rod 12 is connected to the fixing frame 2 via a bearing.

[0028] The central shaft 11 and the upper mold 5 are an integral structure.

[0029] The working principle of a lacquer porcelain jewelry mold provided by the utility model is as follows: Figure 1-Figure 3As shown, when in use, the fixing frame 2 is connected to the conveying chain through the connecting plate 4. After the embryo raw material is dripped into the lower ball groove 7, the fixing frame 2 is moved to the lower side of the upper mold 5 along the guide rail 1 through the rubber wheel 13. A limiter is set on the inner bottom side of the guide rail 1 corresponding to the position of the upper mold 5, so that the fixing frame 2 and the bottom mold 6 can be accurately moved to the lower side of the upper mold 5. The hydraulic cylinder can push the upper mold 5 to move downward, so that the upper mold 5 and the bottom mold 6 are closed, and then the embryo is squeezed into a lacquer porcelain bracelet ball with a through hole on the inside, simplifying the production steps of the bracelet ball, and then improving the production efficiency. After extrusion molding, the fixing frame 2 continues to move to the subsequent processing equipment, and the electric push rod 12 can push the bottom mold 6 to rotate around the rotating shaft 14, so that the bottom mold 6 is flipped upward, so that the embryo in the lower ball groove 7 is released from the bottom mold 6, which is convenient for subsequent production.
