Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of molds, and more specifically, it refers to an inclined ejector rail-changing mechanism for an automotive air outlet duct. Background Art
[0002] The automotive air outlet duct is a core component of the automotive air conditioning system, responsible for delivering the temperature-regulated and purified air flow to the cockpit to achieve functions such as refrigeration, heating, defrosting, and defogging. Its design directly affects the air flow speed, direction, and comfort inside the vehicle.
[0003] Automotive air outlet ducts are generally plastic parts and are injection-molded. The automotive air outlet duct is a product with an irregular shape and has undercuts. When ejecting the product, an inclined ejector is required. However, several protrusions are provided at the bottom end of the automotive air outlet duct. During the process of ejecting with the inclined ejector, the protrusions are on the moving path of the inclined ejector, resulting in interference between the inclined ejector and the product and preventing normal ejection. Summary of the Invention
[0004] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide an inclined ejector rail-changing mechanism for an automotive air outlet duct to solve the technical problem that the inclined ejector interferes with the automotive air outlet duct product during the ejection process and cannot be ejected normally in the prior art.
[0005] To solve the above technical problems, the present invention provides an inclined ejector rail-changing mechanism for an automotive air outlet duct, which includes a base, an ejector plate, a lower mold, and a rail-changing assembly. The lower mold is fixedly connected above the base. The ejector plate is vertically movably arranged between the lower mold and the base. The rail-changing assembly includes a rail-changing slide base, an inclined ejector, a connecting block, and a parallel rod. The rail-changing slide base is fixedly connected to the ejector plate. A track is provided on the rail-changing slide base. The track includes a horizontal section and an inclined section that is connected to one end of the horizontal section and is inclined downward. The connecting block is slidably connected to the track. The parallel rod is fixedly connected to the base and is inclined upward. The connecting block is slidably connected to the parallel rod. The inclined ejector is fixedly connected to the connecting block. The upper end of the inclined ejector passes through the lower mold and abuts against the product on the lower mold.
[0006] After adopting the above structure, the inclined ejector rail-changing mechanism for an automotive air outlet duct of the present invention has the following advantages: During ejection, the ejector plate moves upward to drive the rail-changing slide base, the inclined ejector, and the connecting block to move upward. The inclined parallel rod plays a guiding role. During the process of moving upward with the ejector plate, the connecting block is guided by the parallel rod and slides horizontally within the horizontal section, thereby driving the inclined ejector to move horizontally, separating the inclined ejector from the undercut of the product. As the ejector plate continues to rise, the connecting block moves into the inclined section, driving the inclined ejector to move obliquely downward, thereby enabling the inclined ejector to avoid several protrusions at the bottom end of the product, avoiding interference between the inclined ejector and the product during the ejection process, and ensuring normal ejection of the inclined ejector.
[0007] As an improvement, there are two relatively arranged rail-changing sliders in the rail-changing assembly. The two rail-changing sliders are provided with tracks facing each other, and the connecting block is slidably connected between the two rail-changing sliders. With this structure, the sliding connection between the connecting block and the rail-changing slider is more stable.
[0008] As an improvement, a convex post is provided on the side wall of the connecting block, and a bearing is rotatably connected to the convex post. The bearing is slidably connected in the track. With this structure, the sliding friction is converted into rolling friction, reducing the wear of the track and improving the movement accuracy, and avoiding jamming during the ejection process.
[0009] As an improvement, the inclined ejector is arranged parallel to the parallel rod.
[0010] As an improvement, the inclined ejector includes a ejector rod and a ejector block. The lower end of the ejector rod is fixedly connected to the connecting block, and the upper end of the ejector rod passes through the lower die and is fixedly connected to the ejector block. The ejector block abuts against the product on the lower die. With this structure, the ejector block is used to form the undercut structure in the product, and when ejecting, the ejector rod drives the ejector block to move so as to disengage from the undercut.
[0011] As an improvement, the lower die is provided with a through hole, and a guide sleeve is connected in the through hole. The ejector rod is slidably connected in the guide sleeve. With this structure, it prevents the wear of the ejector rod and the lower die caused by the direct contact between the ejector rod and the lower die.
[0012] As an improvement, a limiting block that abuts against the bottom end of the guide sleeve is fixedly connected to the bottom end of the lower die. With this structure, it prevents the guide sleeve from moving downward and disengaging from the lower die.
[0013] As an improvement, a groove is provided on the upper end surface of the ejector plate, and the rail-changing slider is fixedly connected in the groove. A limiting groove is provided on the side wall of the rail-changing slider, and a limiting portion located in the limiting groove is provided on the side wall of the groove. With this structure, the overall structure is more compact, and the limiting portion cooperates with the limiting groove to play a limiting role, improving the connection stability between the rail-changing slider and the ejector plate.

Detailed implementation manner
[0022] The following will make a detailed description of an inclined ejector track-changing mechanism for an automobile air outlet duct in the present invention with reference to the drawings.
[0023] As Figures 1 to 7 shown, an inclined ejector track-changing mechanism for an automobile air outlet duct includes a base 1, an ejector plate 2, a lower die 3, and a track-changing assembly 4. The lower die 3 is fixedly connected above the base 1. The ejector plate 2 is vertically movably arranged between the lower die 3 and the base 1. The track-changing assembly 4 includes a track-changing sliding seat 41, an inclined ejector 42, a connecting block 43, and a parallel rod 44. The track-changing sliding seat 41 is fixedly connected to the ejector plate 2. A track 5 is provided on the track-changing sliding seat 41. The track 5 includes a horizontal section 51 and an inclined section 52 that is obliquely downward and connected to one end of the horizontal section 51. The horizontal section 51 and the inclined section 52 are transitioned through an arc section. The connecting block 43 is slidably connected to the track 5 and can slide along the track 5. The parallel rod 44 is fixedly connected to the base 1 and is obliquely upward. The connecting block 43 is slidably connected to the parallel rod 44. The upper end of the inclined ejector 42 passes through the lower die 3 and abuts against the product on the lower die 3.
[0024] Specifically, the connecting block 43 is sleeved on the parallel rod 44. The inclined direction of the parallel rod 44 matches the extending direction of the track 5. That is to say, as Figure 1 shown, the horizontal section 51 of the track 5 is on the left side and the inclined section 52 is on the right side. When ejecting, the moving direction of the connecting block 43 is to move rightward on the horizontal section 51 first and then obliquely rightward and downward on the inclined section 52. Therefore, the parallel rod 44 is obliquely upward from left to right.
[0025] As Figure 2 shown, two relatively arranged track-changing sliding seats 41 are provided in the track-changing assembly 4. Tracks 5 are provided facing each other on the two track-changing sliding seats 41. The connecting block 43 is slidably connected between the two track-changing sliding seats 41; as Figure 3As shown, a convex post 6 is provided on the side wall of the connecting block 43. A bearing 7 is rotatably connected to the convex post 6, and the bearing 7 is slidably connected in the track 5. Specifically, convex posts 6 are provided on two opposite side walls of the connecting block 43, a bearing 7 is rotatably connected to each convex post 6, and the two bearings 7 are respectively slidably connected in the two tracks 5.
[0026] As Figure 3 shown, the lifter 42 is arranged in parallel with the parallel rod 44. The lifter 42 includes a top rod 421 and a top block 422. The lower end of the top rod 421 is fixedly connected to the connecting block 43, and the top rod 421 is arranged in parallel with the parallel rod 44. The upper end of the top rod 421 passes through the lower die 3 and is fixedly connected to the top block 422. The top block 422 abuts against the product on the lower die 3. Specifically, the top block 422 is directly used for forming the undercut structure in the product of the lower die 3.
[0027] As Figure 1 and Figure 2 shown, the lower die 3 is provided with a through hole 8. A guide bushing 9 is connected in the through hole 8. The top rod 421 is slidably connected in the guide bushing 9. A limit block 10 that abuts against the bottom end of the guide bushing 9 is fixedly connected to the bottom end of the lower die 3.
[0028] As Figure 4 shown, a groove 11 is provided on the upper end surface of the ejector plate 2. The track-changing slide base 41 is fixedly connected in the groove 11. A limit groove 12 is provided on the side wall of the track-changing slide base 41, and a limiting portion 13 located in the limit groove 12 is provided on the side wall of the groove 11.
[0029] In this embodiment, as Figure 2 shown, there are a total of two sets of track-changing assemblies 4.
[0030] Before ejection, the bearing 7 is located in the horizontal section 51. During ejection, the upward movement of the ejector plate 2 drives the track-changing slide base 41, the lifter 42 and the connecting block 43 to move upward. The inclined parallel rod 44 plays a guiding role. The connecting block 43 slides horizontally in the horizontal section 51 under the guiding action of the parallel rod 44 during the upward movement with the ejector plate 2, thereby driving the lifter 42 to move horizontally, separating the lifter 42 from the undercut of the product. At this time, the movement path of the top block 422 is as Figure 5 shown; as the ejector plate 2 continues to rise, the bearing 7 of the connecting block 43 moves into the inclined section 52, driving the lifter 42 to move obliquely downward, so that the lifter 42 avoids several protrusions at the bottom end of the product. At this time, the movement path of the top block 422 is as Figure 6 shown. Finally, the top block 422 reaches the position as Figure 7 shown, avoiding interference between the lifter 42 and the product during the ejection process and ensuring normal ejection of the lifter 42.
[0031] The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the above-described embodiment. All other embodiments obtained by those skilled in the art without creative efforts fall within the scope of protection of the present invention.
