[0022] Refer to Figures 1-3 , a TV shell mold convenient for demolding, comprising: a mold body 1, rotating structures are respectively installed on two side wall surfaces of the mold body 1, a bracket structure is installed on the front wall surfaces of the two rotating structures, a power structure is installed on the rear wall surface of the mold body 1, a transmission structure is installed between the rotating structure and the power structure, an atomizing structure is installed inside the bracket structure, and a conveying structure is installed at the tail of the atomizing structure; the rotating structure includes: a rotating support plate 2, a rotating shaft 3 and a rotating seat 4; the rotating support plate 2 is installed on the side wall surface of the mold body 1, the rotating seat 4 is movably sleeved on the rotating support plate 2 through the rotating shaft 3, the power structure includes: a limit support plate 5 and a power motor 6; the limit support plate 5 is installed on the rear wall surface of the mold body 1, the power motor 6 is installed on the front wall surface of the limit support plate 5, the transmission structure includes: a driving gear 7 and a driven gear 8; the driving gear 7 is installed on the driving end of the power motor 6, the driven gear 8 is installed on the upper wall surface of the rotating shaft 3, and the driven gear 8 meshes with the driving gear 7. The driven gear 8 is a non-complete gear of 90 degrees, and the driving gear 7 can drive the driven gear 8 to rotate 90 degrees through one week of engagement. Driven by the power of the power structure, the transmission structure can drive the rotating structure to rotate 90 degrees, so as to facilitate the replacement of the demolding position and the avoidance position of the structure and facilitate the spraying of the demolding agent.

[0023] Specifically, the bracket structure includes: a right-angle bracket 9 and a nozzle bracket 10; the right-angle bracket 9 is installed on the front wall surface of the rotating seat 4, and the nozzle bracket 10 is installed at the tail of the right-angle bracket 9. The nozzle bracket 10 is provided with a number of holes, which can support the atomization structure and the conveying structure, facilitating the transportation of the release agent by the two.

[0024] Specifically, the atomization structure includes: a number of atomizing nozzles 11 and a nozzle connecting pipe 12; the number of atomizing nozzles 11 are respectively installed in the holes of the nozzle bracket 10, and the nozzle connecting pipe 12 is installed at the tail of the number of atomizing nozzles 11. The conveying structure includes: a conveying hose 13, a pipe bracket 14 and a solenoid valve 15; the pipe bracket 14 is installed outside the right-angle bracket 9, the conveying hose 13 is installed inside the pipe bracket 14, and one end of the conveying hose 13 is connected to the nozzle connecting pipe 12. The solenoid valve 15 is installed outside the conveying hose 13. The conveying structure can transport the release agent from the container to the atomization structure, and then under the external pressure, the release agent can be sprayed out from the atomization structure, so that the release agent is evenly sprayed inside the mold body 1.

[0025] Working principle: First, install the mold body 1 on the injection molding machine, and at the same time connect the release agent container with pressure to the conveying hose 13. Then the operator provides energy for the electrical appliances in the present invention with an external AC power supply. When the injection molding machine is opened and the mold body 1 is in the open mold state, the power motor 6 drives the driving gear 7 to rotate, and drives the driven gear 8 to rotate through meshing. When the driving gear 7 rotates one week, it drives the driven gear 8 to rotate 90 degrees, that is, drives the rotating shaft 3 to rotate 90 degrees. At the same time, the rotating shaft 3 drives the rotating seat 4, the right-angle bracket 9 and the nozzle bracket 10 to rotate 90 degrees. At this time, the nozzle bracket 10 and the number of atomizing nozzles 11 face the inside of the mold body 1. At the same time, the solenoid valve 15 is opened, and the release agent passes through the conveying hose 13 and the nozzle connecting pipe 12, and finally the release agent is sprayed into the inside of the mold body 1 through the number of atomizing nozzles 11. When a layer of release agent adheres to the inner wall of the mold body 1, the power motor 6 drives the driving gear 7 to rotate in the reverse direction, and drives the driven gear 8 to rotate through meshing. When the driving gear 7 rotates one week in the reverse direction, it drives the driven gear 8 to rotate 90 degrees in the reverse direction, that is, drives the rotating shaft 3 to rotate 90 degrees in the reverse direction. At the same time, the rotating shaft 3 drives the rotating seat 4, the right-angle bracket 9 and the nozzle bracket 10 to rotate 90 degrees in the reverse direction. At this time, the injection molding machine can be closed to drive the mold body 1 to be buckled. When the injection is completed and the mold is opened again, under the action of the release agent, the internal TV shell injection molding is very easy to fall off.

[0026] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
