[0002] In the field of injection mold manufacturing, injection molds are tools for producing plastic products, and also tools for giving plastic products a complete structure and precise dimensions. Injection molding is a processing method used for mass production of certain complex-shaped parts, such as printer covers, and usually requires the design of special demolding aids.

[0003] A search revealed that Chinese patent application number 2019206065116 discloses "an auxiliary demolding device for an injection mold of a printer cover plastic part". The patent's baffle can prevent the injection liquid from overflowing during injection, making it easier for the injection mold to work. The cylinder lifts the printer housing after injection through the demolding rod, making it easier for the staff to pick up the printer housing after injection.

[0004] The device has a complex structure due to the large number of cylinders, which not only increases the cost of mold manufacturing, but also increases the difficulty of debugging and maintenance due to the requirements of air circuit layout and synchronous control. Furthermore, the cylinders are prone to problems such as seal wear and air pressure fluctuations during long-term high-frequency use, which affects the stability of demolding. In addition, the multi-cylinder system has high energy consumption. Summary of the Invention

[0005] The purpose of this invention is to provide an auxiliary demolding device for the injection mold of the cover plastic part of a printer, which has the characteristics of low cost, simple maintenance and debugging, high demolding stability and low energy consumption.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An auxiliary demolding device for an injection mold of a printer cover plastic part is provided, including a worktable. A lifting groove is provided on the top of the worktable, and a turntable groove is provided inside the worktable. Multiple telescopic grooves are provided on the inner wall of the turntable groove. A motor is installed at the bottom of the worktable, and the output end of the motor is fixedly connected to a turntable. Multiple linkage grooves are provided inside the turntable. Each of the multiple telescopic grooves has a telescopic plate inside, and a linkage column is fixedly connected to the bottom of the telescopic plate. Guide columns are fixedly connected to both sides of the outer wall of the telescopic plate away from the turntable. A lifting plate is provided inside the lifting groove, and a guide plate is fixedly connected to the bottom of the lifting plate. Multiple guide plates are arranged in pairs, and a guide groove is provided inside the guide plate. The guide column is located inside the guide groove. A limit block is fixedly connected to the top of the telescopic plate. A limit groove is provided on the top of the inner wall of the turntable groove, and multiple limit grooves are provided. The limit block is located inside the limit groove.

[0007] Optionally, the end of the telescopic plate furthest from the turntable is located between the two guide plates in the same group, and the guide groove is L-shaped.

[0008] Optionally, the outer wall of the workbench is provided with heat dissipation vents, and there are multiple heat dissipation vents. The heat dissipation vents are connected to the turntable groove through telescopic grooves.

[0009] Optionally, a gantry frame is fixedly connected to the top of the workbench, a hydraulic cylinder is installed on the top of the inner wall of the gantry frame, an upper mold is fixedly connected to the bottom of the hydraulic cylinder, a vent hole is provided on the top of the upper mold, a hollow groove is provided at the corner of the upper mold, a slide bar is provided on the inner wall of the hollow groove, and there are two slide bars.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This utility model includes a motor, a turntable, a linkage groove, a telescopic plate, a guide column, a lifting plate, a guide plate, a guide groove, a limiting block, and a limiting groove. After the upper and lower molds are pressed together, the motor runs, driving the turntable to rotate clockwise. When the turntable rotates, the linkage column is located in the linkage groove inside the turntable, and the limiting block on the top of the telescopic plate is located inside the limiting groove, causing the telescopic plate to move away from the turntable. When the telescopic plate moves, the guide column connected to it moves along the guide groove inside the guide plate. Since the guide groove is L-shaped... In this design, as the guide column moves along the guide plate to the highest point of the guide groove, the guide plate and lifting plate move downwards a short distance, causing the lifting plate to detach from the molded cover. Then, the guide column moves along the guide groove to the lowest point on the right side of the groove, causing the lifting plate to rise. Since the lowest point on the right side of the guide groove is lower than the initial position, the lifting plate eventually rises from the lifting groove, lifting the cover off the lower mold and demolding it. After the cover is removed, the motor reverses its direction, and similarly, the lifting plate is reset to be flush with the upper surface of the worktable. This invention uses a single motor drive and leverages the interlocking of components, resulting in low cost, simple maintenance and debugging, high demolding stability, and low energy consumption.

[0030] Reference Figure 1-9This invention provides an auxiliary demolding device for an injection mold of a printer cover plastic part. The auxiliary demolding device includes a worktable 1. A lifting groove 2 is provided on the top of the worktable 1. A turntable groove 3 is provided inside the worktable 1. Multiple telescopic grooves 4 are provided on the inner wall of the turntable groove 3. A motor 5 is installed at the bottom of the worktable 1. A turntable 6 is fixedly connected to the output end of the motor 5. Multiple linkage grooves 7 are provided inside the turntable 6. Each of the multiple telescopic grooves 4 has a telescopic plate 8 inside. A linkage column 9 is fixedly connected to the bottom of the telescopic plate 8. Guides are fixedly connected to both sides of the outer wall of the end of the telescopic plate 8 away from the turntable 6. The lifting plate 11 is provided inside the lifting column 10 and the lifting groove 2. The bottom of the lifting plate 11 is fixedly connected to the guide plate 12, and there are multiple guide plates 12. The multiple guide plates 12 are grouped in pairs. The end of the telescopic plate 8 away from the turntable 6 is located in the middle of the two guide plates 12 in the same group. The guide plate 12 has a guide groove 13 inside. The guide groove 13 is L-shaped. The guide column 10 is located inside the guide groove 13. The top of the telescopic plate 8 is fixedly connected to the limiting block 14. The top of the inner wall of the turntable groove 3 has a limiting groove 15, and there are multiple limiting grooves 15. The limiting block 14 is located inside the limiting groove 15.

[0031] After the upper mold 19 and the lower mold 26 are pressed together, the motor 5 runs, driving the turntable 6 to rotate clockwise. When the turntable 6 rotates, the linkage column 9 is located in the linkage groove 7 opened inside the turntable 6, and the limiting block 14 set on the top of the telescopic plate 8 is located inside the limiting groove 15, thereby causing the telescopic plate 8 to move away from the turntable 6. When the telescopic plate 8 moves, the guide column 10 connected to it moves along the guide groove 13 opened inside the guide plate 12. Since the guide groove 13 is L-shaped, the guide column 10 moves along the guide plate 12 to the highest point of the guide groove 13. During the process, the guide plate 12 and the lifting plate 11 move downwards a short distance, causing the lifting plate 11 to detach from the molded cover. Then, the guide column 10 moves along the guide groove 13 to the lowest point on the right side of the guide groove 13, causing the lifting plate 11 to rise. Since the lowest point on the right side of the guide groove 13 is lower than the initial position, the lifting plate 11 can eventually rise from the lifting groove 2, lifting the cover off the lower mold 26 and demolding the cover. After the cover is removed, the motor 5 runs in reverse, and similarly, the lifting plate 11 is eventually reset and flush with the upper surface of the worktable 1. This utility model adopts a single motor drive method, utilizing the mutual linkage between components, and has the characteristics of low cost, simple maintenance and debugging, high demolding stability, and low energy consumption.
