[0002] A digital video converter box (STB), often called a set-top box or set-top box, is a device that connects a television set to an external signal source. It converts compressed digital signals into video content and displays it on the television. The production of a set-top box typically requires injection molding of its outer casing.
[0003] When using existing set-top box injection molds, the molded set-top box is typically ejected from the mold cavity using a mold ejector pin, and then manually removed by a worker. However, this method of removing the material places the set-top box between the bottom and top molds of the mold, a relatively narrow space. This repetitive removal process by the worker can easily cause the set-top box to collide with the mold, thus affecting the quality of some set-top boxes. Therefore, an injection mold for set-top box production is proposed. Utility Model Content

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.
[0020] The utility model provides a technical solution: Figures 1 to 4 As shown, in this embodiment, an injection mold for producing a set-top box includes a bottom mold 1, a top mold 2 is arranged above the bottom mold 1, and a material picking mechanism acting on the set-top box is arranged between the bottom mold 1 and the top mold 2. The material picking mechanism consists of a horizontal adjustment component, a placement plate 5 and a vertical adjustment component. The fixed end of the horizontal adjustment component is fixedly connected to the bottom mold 1, and the fixed end of the vertical adjustment component is fixedly installed on the driving end of the horizontal adjustment component. The placement plate 5 is fixedly connected to the driving end of the vertical adjustment component.
[0021] The upper surface of the placement plate 5 is frosted.
[0022] Such an arrangement can increase the friction between the placement plate 5 and the set-top box, thereby preventing the set-top box from sliding off the placement plate 5 .
[0023] Among them, the horizontal adjustment component consists of a guide plate 3, a movable plate 4, a first motor 6, a first screw 7 and a movable block 8. The two guide plates 3 are respectively fixedly connected to the two sides of the base mold 1. A movable plate 4 is arranged between the two guide plates 3. The two sides of the movable plate 4 are respectively slidably installed in the movable grooves 9 opened in the two guide plates 3. The bottom of the movable plate 4 is fixedly installed with a movable block 8. The first motor 6 is fixedly embedded in the side wall of the base mold 1. The end of the output shaft of the first motor 6 is fixedly connected with the first screw 7. The first screw 7 is horizontally arranged. The first screw 7 passes through the movable block 8 and is connected to the movable block 8 by threaded fitting.
[0024] When in use, the first motor 6 is started to drive the first screw 7 to rotate, thereby driving the movable block 8 to move along the axial direction of the first screw 7, and further driving the movable plate 4 to move in the horizontal direction.
[0025] Among them, the vertical adjustment component consists of a mounting frame 10, a slider 13, a second lead screw 14, and a second motor 15. The mounting frame 10 is fixedly installed on the upper end of the movable plate 4 by two fixing bolts 11. The placement plate 5 is located between the mounting frame 10 and the bottom mold 1. The placement plate 5 is fixedly connected to the end of the mounting frame 10 close to the mounting frame 10 with a slider 13. The slider 13 is slidably installed in a slide groove 16 opened on the mounting frame 10. A second lead screw 14 is rotatably installed in the slide groove 16. The second lead screw 14 is vertically arranged. The second lead screw 14 passes through the slider 13 and is connected to the slider 13 by threaded fitting. A second motor 15 is fixedly installed on the upper end of the mounting frame 10, and the output shaft of the second motor 15 is fixedly connected to the second lead screw 14.
[0026] When in use, the second motor 15 is started to drive the second lead screw 14 to rotate, thereby controlling the slider 13 to move in the slide groove 16, and further controlling the height of the placement plate 5.
[0027] Among them, guide blocks 18 are respectively provided on both sides of the slider 13. The two guide blocks 18 are fixedly connected to the placement plate 5. The two guide blocks 18 are respectively slidably installed in two guide grooves 17 opened on the mounting frame 10.
[0028] The guide blocks 18 and the guide grooves 17 can make the placement plate 5 move more smoothly when moving up and down.
[0029] The placement plate 5 is provided with a plurality of through slots 12 .
[0030] When the placement plate 5 extends under the set-top box, the through slot 12 can prevent the ejector pin from coming into contact with the placement plate 5 .
[0031] The length of the movable groove 9 is greater than the sum of the lengths of the placement plate 5 and the movable plate 4 .
[0032] Such an arrangement can ensure that the placement plate 5 can be completely separated from between the bottom mold 1 and the top mold 2.
[0033] The utility model provides an injection mold for set-top box production, and the specific working principle is as follows:
[0034] When in use, the bottom mold 1 is fixedly mounted on the injection molding machine, and the top mold 2 is fixedly mounted on the driving module of the injection molding machine. After the set-top box is injection-molded, the set-top box is ejected by the ejector inside the bottom mold 1, and then the first motor 6 is started to drive the first screw 7 to rotate, thereby driving the movable block 8 to move along the axial direction of the first screw 7, and then driving the movable plate 4 to move in the horizontal direction, controlling the movable plate 4 to move toward the bottom mold 1, thereby extending the placement plate 5 between the bottom mold 1 and the ejected set-top box, and the through groove 12 provided on the placement plate 5 can prevent the ejector from interfering with the placement plate 5, and then starting the second motor 15 to drive the second screw 14 to rotate, thereby controlling the slider 13 to move in the slide groove 16, and then adjusting the height of the placement plate 5, controlling the placement plate 5 to move upward, and the set-top box can be lifted up, separating the set-top box from the ejector, and finally controlling the movable plate 4 to move in the direction away from the bottom mold 1, and the set-top box can be taken out of the mold. At this time, the staff can easily take away the set-top box to avoid collision between the set-top box and the mold during the material retrieving process.
[0035] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
