[0002] Gear forging usually requires the use of a forging die. After the forging die is used, it is usually necessary to use materials such as graphite emulsion as a demolding material and spray it into the die through an inkjet device. The inkjet device currently used usually moves the ejection part to a specified position through a driving mechanism such as a motor or a cylinder, and then sprays ink. For example, a patent with publication number CN211071630U discloses an automatic inkjet device for a forging die. By setting a driving component, the cylinder can drive the installation part to move, and can automatically extend the guide rod with a nozzle after the forging operation is completed and the workpiece is taken out to complete the spraying operation. However, the above technical solution requires that the cylinder be started by the control module after the mold is fully opened. The cylinder start-up usually requires manual start-up, which requires manpower and is not efficient. Utility Model Content

[0019] The essential features and advantages of the present invention are further described below in conjunction with examples, but the present invention is not limited to the examples listed.

[0020] like Figures 1 to 4As shown, a high-efficiency inkjet device for gear forging of this embodiment includes a column 1, a lifting part 2, a fixed part 3, a connecting rod assembly 4 and a moving assembly 5. The column 1 is provided with a slide rail 11 and a positioning assembly 12. The slide rail 11 is vertically arranged. The lifting part 2 is matched with the slide rail 11 and connected to the upper die 10 of the mold. It rises and falls and slides along the slide rail 11. When the mold is opened, the upper die 10 moves upward or downward by the mold driving mechanism, thereby driving the lifting part 2 to move synchronously along the slide rail. The fixed part 3 is arranged below the column 1 and below the lifting part 2. The connecting rod assembly 4 includes a first connecting rod 41, a second connecting rod 42 and a third connecting rod 43. The two ends of the first connecting rod 41 are pivotally connected to the fixed part 3 and the third connecting rod 43 respectively. The two ends of the second connecting rod 42 are pivotally connected to the lifting part 2 and the first connecting rod 41 respectively. The third connecting rod 43 is pivotally connected to the moving assembly 5. The moving assembly 4 is slidably connected to the positioning assembly 12. The moving assembly 3 is provided with an inkjet part 6. In the above technical solution, when the upper mold 10 moves upward and opens, the upper mold 10 drives the lifting part 2 to move upward along the slide rail 11, the distance between the lifting part 2 and the fixed part 3 increases, the second connecting rod 42 pulls the first connecting rod to rotate toward the upper mold, and the first connecting rod 41 pulls the third connecting rod 43 to move toward the upper mold, thereby driving the moving assembly 5 to move toward the mold, so that the inkjet unit 6 moves to the top of the lower mold 20 and can spray ink into the lower mold; multiple inkjet units 6 can be set to increase the coverage. Through the above technical solution, when the upper mold is opened, the moving assembly 5 can be moved toward the mold without the need for an additional power source to drive it, thereby realizing linkage control with the mold, improving usage efficiency, and reducing control costs.

[0021] In this embodiment, the positioning assembly 12 includes a positioning plate 121 and a guide plate 122, the guide plate 122 is connected to the positioning plate 121, a guide rail 123 is provided on the guide plate 122, and the moving assembly 5 is connected to the guide rail 123. Through the above technical solution, the moving assembly 5 can be moved along the extension direction of the guide rail 123. The guide plate 123 is provided with an arc groove 124, and the positioning plate 121 and the guide plate 123 are connected through the arc groove 124, so that the angle between the positioning plate 121 and the guide plate 123 can be adjusted, and the positioning plate 121 and the guide plate 123 can be locked or released by the bolt 7 inserted into the arc groove 124.

[0022] In this embodiment, the moving assembly 5 includes a slider 51 and a mounting seat 52 connected to the slider 51. The inkjet unit 6 is disposed on the mounting seat 52. The slider 51 is connected to the third connecting rod 43 and is clamped on the guide rail 123, so that the slider 51 can slide relative to the guide rail 123 through the third connecting rod 43, and at the same time drive the mounting seat 52 to move, so that the inkjet unit 6 moves. The second connecting rod 42 is pivotally connected to the middle part of the first connecting rod 41, and an adjustment hole 431 is provided in the middle part of the third connecting rod 43. The adjustment hole 431 is correspondingly arranged with the second connecting rod 42, so that the second connecting rod 42 can be pivotally connected through the adjustment hole 431 to adjust the stroke of the third connecting rod 43.

[0023] In this embodiment, the inkjet unit 6 includes a main body 61, a sliding part 62 is provided in the main body 61, a fluid cavity 63 is provided on one side of the sliding part 62, and the fluid cavity 63 is provided with an inlet part 64 and an outlet part 65. The demoulding material in the fluid cavity 63 is ejected through the outlet part 65 by sliding of the sliding part 62, and the demoulding material enters the fluid cavity 63 through the inlet part 64. The main body 61 is provided with a first cavity 611 and a second cavity 612 which are interconnected. The inner diameter of the first cavity 611 is larger than that of the second cavity 612. The sliding part 62 includes a plug body 621 and a rod body 622 which are connected to each other. The plug body is located in the first cavity, and the rod body is located in the second cavity. The rod body passes through a sealing plug 66 in the second cavity, and the sealing plug 66 and the main body 61 form a fluid cavity 63. Through the above technical solution, the plug body 621 can move in the first cavity 611 and will not enter the second cavity 612. The plug body 621 drives the rod body 622 to move in the fluid cavity 63, thereby squeezing the demoulding material in the fluid cavity 63 out. The inlet 64 and the outlet 65 are both connected to the fluid cavity 63. When the plug body 621 moves upward, the fluid volume in the fluid cavity 63 increases, and the demoulding material enters the fluid cavity through the inlet 64. When the plug body 621 moves downward, the extruded demoulding material is output from the outlet 65. In this embodiment, multiple outlets 65 are provided to expand the spraying range. The plug body 621 divides the first cavity 611 into a first air cavity 613 and a second air cavity 614. The first and second air cavities have airflow ports 615 respectively. The upward or downward movement of the plug body 621 is controlled by the airflow ports 615. The airflow ports 615 are connected to the external air supply device 30, such as an existing air supply device such as an air compressor. When the first air cavity 613 is inhaled, the plug body 621 moves downward, and the second air cavity 614 is exhausted; when the second air cavity 614 is inhaled, the plug body moves upward, and the first air cavity is exhausted. Through the above technical solution, the ejection of the demoulding material can be controlled by air pressure, which is convenient for controlling the ejection pressure and avoiding excessive pressure. Sealing rings 67 are provided on both sides of the sealing plug 66 to improve the sealing performance and avoid leakage.

[0024] A high-efficiency inkjet device for gear forging in this embodiment can be controlled in linkage with a mold without the need for an additional power source, thereby improving utilization efficiency and reducing control costs.

Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
