[0021] In this embodiment of the invention, a positioning and conveying assembly is used for positioning and placing the injection molded housing part and for step-by-step conveying. When cutting the gate of the injection molded housing part, the orientation of the cutter 13 is first controlled and adjusted by the steering adjustment assembly. Then, the vertical telescopic cylinder 8 is extended. With the setting of the elastic element 11 and the fixed ring plate 12, the fixed ring plate 12 can elastically press and fix the injection molded housing part until the cutter 13 reaches the specified longitudinal position. Then, the XY direction drive assembly 19 is used to drive the horizontal movable plate 18 to move in the X or Y direction as needed, so that the cutter 13 can complete the gate cutting work of the injection molded housing part. The fixing and cutting are integrated, the operation is stable and reliable, the control is simple, and the application range is wide.

[0022] like Figure 1-2 As shown, in a preferred embodiment of the present invention, the positioning and conveying assembly includes a side frame 2, a conveyor motor 3, a roller 4, and a conveyor belt 5. A roller 4 is provided on each side of the machine base 1, and a conveyor belt 5 is wound between the two rollers 4. The surface of the conveyor belt 5 is evenly provided with a plurality of limiting grooves 6 for placing the injection molded shell parts. The shape of the limiting grooves 6 is not limited and can be adapted to the shape of the injection molded shell parts. The two ends of the roller 4 are rotatably mounted with the side frame 2, and the lower end of the side frame 2 is fixed to the machine base 1. A conveyor motor 3 is also fixed on one of the side frames 2 and is driven to the end of the roller 4. The conveyor motor 3 is used to drive the roller 4 to rotate in a stepping manner, thereby driving the conveyor belt 5 to move in a stepping manner, so as to realize the connection and cutting of the gate for the injection molded shell parts.

[0023] In one embodiment, multiple rollers 16 are also closely attached to the lower side of the upper branch of the conveyor belt 5. The rollers 16 are used to support the conveyor belt 5. Side plates 15 are rotatably installed at both ends of the rollers 16. Auxiliary support frames 14 are also fixed on the side plates 15.

[0025] The fixing ring plate 12 adopts a U-shaped structure. The fixing ring plate 12 is used to press and fix the outer side of the injection molded shell. The elastic element 11 is preferably provided with four springs on the outer side of the fixing ring plate 12 to improve the reliability of the elastic element 11 supporting the fixing ring plate 12.

[0026] A horizontal movable cavity 17 is provided on the upper inner wall of the fixed cylinder 10. The outer ring of the horizontal movable plate 18 is slidably connected to the horizontal movable cavity 17. The horizontal movable plate 18 can move in any direction without slipping out of the horizontal movable cavity 17, thus ensuring the reliability of the adjustment of the horizontal movable plate 18.

[0027] like Figure 3-5 As shown, in a preferred embodiment of the present invention, the XY direction drive assembly 19 includes teeth 26, a first fixing plate 27, a first long gear 28, a first cutting motor 29, a second fixing plate 30, a second long gear 31, and a second cutting motor 32. A plurality of teeth 26 are evenly distributed and fixed on the upper side of the horizontal movable plate 18. The teeth 26 are preferably frustum structures, and the outline shape formed by the plurality of teeth 26 is square. Two first fixing plates 27 are fixed on the lower side of the top plate 9, and the lower ends of the two first fixing plates 27... A long gear 28 is rotatably mounted and meshes with the teeth 26. A cutting motor 29, which is driven by the long gear 28, is also fixed on one of the fixed plates 27. Two fixed plates 30 are also fixed on the lower side of the top plate 9. A long gear 31, which meshes with the teeth 26, is rotatably mounted between the lower ends of the two fixed plates 30. The long gear 31 is set perpendicular to the long gear 28. A cutting motor 32, which is driven by the long gear 31, is also fixed on one of the fixed plates 30.

[0028] It should be noted that the long gear 28 and the long gear 31 can be adapted to the tooth 26 without limitation; the lengths of the long gear 28 and the long gear 31 can be the same or different, and the distance between the long gear 28 and the long gear 31 can be flexibly arranged without limitation.

[0029] In practical applications, by controlling the operation of cutting motor 29 and cutting motor 32, and with the vertical setting of long gear 31 and long gear 28, and with both long gear 31 and long gear 28 meshing with teeth 26, the horizontal movable plate 18 can be driven to move in the X and Y directions as needed. Combined with the mounting structure of the horizontal movable plate 18, it is stable and flexible.

[0030] like Figure 3 , 6As shown in Figure 7, in a preferred embodiment of the present invention, the steering adjustment assembly includes a boom 20, a horizontal telescopic cylinder 21, a brake plate 22, a brake wheel 23, a lever 24, and a steering motor 25. The steering motor 25 is fixed to the lower side of the horizontal movable plate 18. The brake wheel 23 is fixedly mounted on the output end of the steering motor 25. The brake plate 22 is provided on one side of the brake wheel 23. The horizontal telescopic cylinder 21 is fixed on the side of the brake plate 22 away from the brake wheel 23. The horizontal telescopic cylinder 21 is also connected and fixed to the horizontal movable plate 18 through the boom 20. The cylinder 21 is used to control whether the brake plate 22 abuts against and fixes the brake wheel 23. A cutter bar 24 is also fixed on the lower side of the brake wheel 23. The cutter bar 24 is coaxially arranged with the output end of the directional motor 25. The cutter 13 is fixed on the side wall of the cutter bar 24 away from the brake wheel 23. The cutter 13 is preferably a concave arc structure in the middle of both sides, and both sides of the cutter 13 are provided with cutting edges. Through the structural limitation of the cutter 13, both sides can cut the gate. The concave arc structure in the middle of both sides of the cutter 13 prevents the gate from slipping and improves the cutting reliability.

[0031] In practical applications, the orientation of the cutter 13 can be flexibly adjusted using the directional motor 25 according to the model of the injection molded shell. The brake plate 22 can be fixed against the brake wheel 23 by the horizontal telescopic cylinder 21. After the cutter 13 is oriented, the cutter 13 can be moved to cut the gate by the individual or combined actions of the cutting motor 1 29 and the cutting motor 2 32. This is convenient, fast, stable and reliable.

[0032] The above embodiments of the present invention provide a gate cutting machine for digital housing injection molding parts. The positioning and conveying assembly is used for positioning and placing the housing injection molding parts and for step-by-step conveying. Specifically, the conveying motor 3 can drive the roller 4 to rotate step by step, thereby driving the conveyor belt 5 to move step by step, so as to realize the connection and gate cutting of the housing injection molding parts.

[0033] When cutting the gate of the injection molded shell, the orientation of the cutter 13 is first controlled by the steering adjustment component. Specifically, the orientation of the cutter 13 can be flexibly adjusted by the steering motor 25, and the brake plate 22 is fixed to the brake wheel 23 by the horizontal telescopic cylinder 21.

[0034] Then, by extending the vertical telescopic cylinder 8, and by using the elastic element 11 and the fixed ring plate 12, the fixed ring plate 12 can elastically press and fix the injection molded part of the housing until the cutter 13 reaches the specified longitudinal position.

[0035] Then, the horizontal movable plate 18 is driven to move in the X or Y direction as needed by the XY direction drive component 19, so that the cutter 13 can complete the gate cutting work of the injection molded shell part. Specifically, by controlling the operation of the cutting motor 1 29 and the cutting motor 2 32, and with the vertical setting of the long gear 2 31 and the long gear 1 28, and the long gear 2 31 and the long gear 1 28 being meshed with the teeth 26, the horizontal movable plate 18 can be driven to move in the X and Y directions as needed. With the installation structure of the horizontal movable plate 18, it is stable and flexible.

[0036] Through the above operations, the gate cutting work of the cutter 13 for the injection molded shell can be completed. The operation is stable and reliable and has a wide range of applications.

[0037] Furthermore, the control of each component can be achieved using a PLC controller disclosed in the existing technology. There are no specific limitations on the model and circuit connection of each component, and they can be flexibly configured in practical applications.

[0038] The circuits, electronic components, and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this invention does not involve any improvement to the software and methods.

[0039] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0040] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
