The debris is automatically collected in conjunction with the slag storage tank and collection box, significantly improving the product qualification rate. The coordinated transmission of the hydraulic support column, hydraulic oil tank, and drive gear-rack enables precise power transmission for the lifting of the support plate and the flipping of the female mold. The unloading component automatically pushes the workpiece to separate from the female mold when the male mold is reset through the mechanical linkage of the guide column, fixed pulley, and rope, reducing manual intervention. Each functional module is compactly integrated into the basic frame such as the support side plate and support plate. The standardized design of key components facilitates maintenance, reducing the frequency of manual cleaning, operational complexity, and long-term use costs, effectively improving production efficiency and economic value.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] In the description of this invention, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0031] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0032] Example 1

[0033] Please see Figures 1-4 The present invention provides a technical solution comprising: a processing base 1, a supporting side plate 2 installed on the top of the processing base 1, a cover plate 9 provided on the top of the supporting side plate 2, symmetrical clearance grooves 29 on both sides of the supporting side plate 2, a supporting plate 6 movably disposed within the clearance grooves 29, a female mold unit 5 installed at the center of the supporting plate 6, a male mold unit 11 installed at the bottom center of the cover plate 9 via a hydraulic cylinder 10, and a stripping assembly 12 installed on the top of the supporting plate 6 and at the rear end of the female mold unit 5.

[0034] Preferably, the fixed end of the hydraulic support 3 is fixedly connected to the processing base 1, the output end of the hydraulic support 3 is fixedly connected to the support plate 6, a hydraulic oil tank 14 is provided in the support side plate 2, the piston 13 is slidably disposed in the hydraulic oil tank 14, one end of the top plate 4 is fixedly connected to the support plate 6, and the other end of the top plate 4 extends movably into the hydraulic oil tank 14 and is fixedly connected to the piston 13.

[0035] Preferably, the support plate 6 has a second clearance groove 30, and the bottom area of ​​the mother mold unit 5 is larger than the area of ​​the second clearance groove 30.

[0036] Preferably, the processing base 1 is provided with a collection box for collecting debris.

[0037] The working principle and beneficial effects of the above technical solution are as follows: After the handrail bracket plate is placed on the female mold unit 5, the hydraulic cylinder 10 is activated to press down the male mold unit 11 and match it with the female mold unit 5 to obtain the required handrail bracket product. During this process, the slag removal knife 27 can simultaneously shape and cut the outer frame of the handrail bracket product during the forming process, thereby improving the product qualification rate. At the same time as the male mold unit 11 is reset, the stripping component 12 can assist the product to detach from the female mold unit 5. When the debris accumulated in the female mold unit 5 reaches the warning value, the hydraulic support column 3 drives the support plate 6 to descend as a whole. At this time, the female mold unit 5 will flip over, and the slag removal knife 23 will scrape off the debris accumulated in the female mold unit 5 and push it out and fall into the collection box set on the processing base 1. It is simple and efficient.

[0038] Example 2

[0039] Based on Example 1, please refer to Figures 1-5 The master mold unit 5 includes: a concave base 19, which is placed on a support plate 6; a lower mold body 20 is installed inside the concave base 19, and a slag storage groove 48 is left between the lower mold body 20 and the concave base 19; a hydraulic oil chamber 21 is opened inside the concave base 19; a piston 22 is slidably disposed inside the hydraulic oil chamber 21; the bottom of the slag removal knife 23 is fixedly connected to the piston 22; the top of the slag removal knife 23 moves through the slag storage groove 48; one end of the return spring 24 is fixedly connected to the piston 22; and the other end of the return spring 24 is fixedly connected to the inner wall of the hydraulic oil chamber 21.

[0040] Preferably, one end of the drive rack 17 is fixedly connected to the support plate 6, and the other end of the drive rack 17 is fixedly provided with a fixed bracket 18. One end of the drive shaft 8 is fixedly connected to the outer wall of the concave base 19, and the other end of the drive shaft 8 movably passes through the support side plate 2 and is fixedly sleeved with a drive gear 16. The drive gear 16 meshes with the drive rack 17.

[0041] Preferably, one end of the hydraulic oil pipe 15 is connected to the hydraulic oil tank 14, and the other end of the hydraulic oil pipe 15 passes through the support side plate 2 and is connected to the connecting oil pipe 7. The end of the connecting oil pipe 7 away from the hydraulic oil pipe 15 is connected to the hydraulic oil tank 21. The support plate 6 is slidably connected to the hydraulic oil pipe 15.

[0042] Preferably, the male mold unit 11 includes: a concave pressure seat 26, which is fixedly sleeved on the outer wall of the upper mold body 25. A clearance groove 49 is left between the concave pressure seat 26 and the upper mold body 25. A slag removal knife 27 is movably disposed in the clearance groove 49, and the slag removal knife 27 is connected to the inner wall of the clearance groove 49 through a reset spring 28.

[0043] The working principle and beneficial effects of the above technical solution are as follows: During use, while the hydraulic cylinder 10 presses down the mold unit 11, the upper mold body 25 will match the lower mold body 20, and the slag removal blade 27 will cut along the outer contour of the lower mold body 20. Thus, the outer frame of the armrest bracket product is simultaneously shaped and cut during the molding process, and the debris can fall directly into the slag storage tank 48 for accumulation. When the space in the slag storage tank 48 is insufficient after multiple processing, the hydraulic support column 3 controls the support plate 6 to descend. The support plate 6 will push the top plate 4 to move down along the support side plate 2 and push the piston 13 to squeeze the hydraulic oil in the hydraulic oil tank 14 into the hydraulic oil tank 21 through the hydraulic oil pipe 15 and the connecting oil pipe 7. At the same time, the drive rack 17 descends synchronously and drives the drive shaft 8 to rotate through the drive gear 16. This causes the concave base 19 to rotate synchronously, and while the supporting plate 6 descends, it provides space for the concave base 19 to flip. In this way, as the concave base 19 flips, the hydraulic oil entering the hydraulic oil tank 21 will simultaneously push out the slag removal knife 23 through the piston 22. At this time, the slag removal knife 23 will adhere to the outer contour of the lower mold body 20 to remove slag and polish (after multiple processing, the outer contour of the lower mold body 20 will inevitably have debris stuck to it). As the concave base 19 flips, the debris inside will fall directly into the collection box set on the processing base 1. Then, while the hydraulic support 3 drives the supporting plate 6 to reset, the mother mold unit 5 can also flip and reset synchronously. The hydraulic oil will also enter the hydraulic oil tank 14 from the hydraulic oil tank 21 along the connecting oil pipe 7 and the hydraulic oil pipe 15, waiting for the next use.

[0044] The setting that the bottom area of ​​the female mold unit 5 is larger than the area of ​​the second relief groove 30 enables the support plate 6 to support the female mold unit 5 and prevent the drive shaft 8 from bearing pressure when the male mold unit 11 descends. The setting of the second relief groove 30 can provide a channel for the falling debris. The fixed bracket 18 can prevent the drive gear 16 from disengaging from the drive rack 17.

[0045] Example 3

[0046] Based on any one of Examples 1-2, please refer to Figures 6-8 The unloading assembly 12 includes: a fixed column 32 and a guide column 34. Both the fixed column 32 and the guide column 34 are fixedly connected to the top of the support plate 6. The outer wall of the fixed column 32 is provided with a fixed pulley 33. The outer wall of the guide column 34 is provided with a guide groove 35. The drive column 37 is slidably connected to the guide groove 35. The outer wall of the drive column 37 is fixedly provided with a rope fixing point 36. The fixed bracket 31 is fixedly connected to the concave pressure seat 26.

[0047] Preferably, the guide column 2 39 is fixedly connected to the fixed column 32, and the guide column 2 39 is provided with a guide groove 2 40. The limiting column 41 is fixedly connected to the fixed column 32. The driving column 43 is movably sleeved on the outer wall of the limiting column 41. The return spring 3 42 is sleeved on the outer wall of the limiting column 41, and one end of the return spring 3 42 is fixedly connected to the fixed column 32. The other end of the return spring 3 42 is fixedly connected to the driving column 43. The outer wall of the driving column 43 is fixedly provided with a rope fixing point 2 46 and a limiting rod 47. The limiting rod 47 is movably disposed in the guide groove 2 40. One end of the connecting rope 38 is fixedly connected to the rope fixing point 1 36. The other end of the connecting rope 38 is wound around the fixed pulley 33 and fixedly connected to the rope fixing point 2 46. The stripper 45 is fixedly connected to the side of the driving column 43 away from the limiting column 41 through the fixing rod 44.

[0048] The working principle and beneficial effects of the above technical solution are as follows: Each time the male mold unit 11 descends, the fixed bracket 2 31 set on the outer wall of the concave pressure seat 26 will press down the drive column 37, so that the drive column 37 moves down along the guide groove 1 35 and at the same time the drive column 43 is pulled along the limit column 41 by the connecting rope 38. While the reset spring 3 42 is compressed, the stripper 45 moves away from the top of the female mold unit 5 to prevent interference with the descent of the male mold unit 11. When the male mold unit 11 is reset, the drive column 37 is no longer blocked by the fixed bracket 2 31. While the reset spring 3 42 pushes the drive column 43 to reset, the stripper 45 will directly push the workpiece processed on the top of the female mold unit 5, thereby separating the workpiece from the female mold unit 5, which is simple and convenient.

[0049] Example 4

[0050] Please see Figure 9 and Figure 10 The present invention also provides a processing mold for use in a processing device for an automobile armrest frame, comprising: a lower mold body 20 and an upper mold body 25. The lower mold body 20 is composed of a lower mold base 50, a lower mold core 51 and a demolding table 53. The lower mold base 50 extends upward to form the lower mold core 51. An annular groove 52 is provided inside the lower mold base 50 and around the lower mold core 51. The demolding table 53 is movably sleeved on the outer wall of the lower mold core 51, and the bottom of the demolding table 53 is inserted into the annular groove 52. A hydraulic rod 54 is installed in the annular groove 52.

[0051] Preferably, the upper mold body 25 is composed of an upper mold support 55 and an upper mold core 56. The bottom of the upper mold support 55 is recessed inward to form the upper mold core 56, and the output end of the hydraulic cylinder 10 is connected to the top of the upper mold support 55.

[0052] Preferably, the mold core 51 and the upper mold core 56 are not limited to the shapes shown in the figure, and need to be replaced according to the shape of the workpiece being processed.

[0053] The working principle and beneficial effects of the above technical solution are as follows: When the upper mold body 25 is pressed down, the upper mold support 55 will first push the demolding table 53 to press down the hydraulic rod 54 until the upper mold core 56 and the lower mold core 51 match and the workpiece will be formed. As the upper mold support 55 is reset, the demolding table 53 will be reset under the push of the hydraulic rod 54, thereby separating the workpiece formed on the lower mold core 51 from it and raising it, so that the stripping component 12 can push the workpiece away.

[0054] in, Figure 9 and Figure 10 The shapes of the lower mold core 51 and the upper mold core 56 are only to indicate their installation position and usage. The lower mold core 51 and the upper mold core 56 are not limited to the shapes shown in the figure and need to be replaced according to the shape of the workpiece being processed.

[0055] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics.
