[0002] The automobile mold automatic part taking-out device is a key component of the automobile mold system, which is used to automatically take out the workpiece from the mold cavity or surface after the mold completes the forming process (stamping, injection molding, die casting, etc.) and transport it to the next process, realizing unmanned production, improving production efficiency, ensuring product quality consistency and reducing labor intensity and safety risk.

[0003] Although the existing technology can embed the ejection component in the mold shell to automatically eject the automobile component 4 after forming through the mold, the material properties and physical structure shapes of different automobile components 4 are not the same, which leads to the need to design a separate ejection mechanism according to different components, resulting in that the automobile mold automatic part taking-out device is only used for corresponding components, the function is completely limited to corresponding components, and the overall cost is high.

[0016] Preferably, a convex frame is connected to the mounting frame, and the slide rod bracket slides through the convex frame.

[0017] The beneficial effects of this invention are:

[0018] 1. The technical solution of the present invention involves moving the inner slide blocks of each upper ring within the upper sliding frame and controlling the rotation of the upper rotating ring within the upper ring so that the ejector rods sliding through the slide blocks can be coaxially aligned with the ejector holes on the mold. Then, the bolts one and two are rotated to ensure the stability of the upper rotating ring and the slide block. The model component is then placed inside the mold so that the model component can abut against the upper ends of each ejector rod, making the upper ends of each ejector rod coplanar with the inner wall of the mold. This allows the ejector rods to seal the ejector holes during the subsequent molding process of the automotive component 4, preventing the surface of the automotive component 4 from being affected by the ejector holes and causing the molding to fail to meet requirements. Then, the telescopic component two is controlled to move downward, driving the connecting plate downward, which pulls the rotating plate one to bring the two side clamps closer together to clamp the ejector rods in this state, ensuring that the upper ends of each ejector rod are at different heights above their respective upper rings and are coplanar with the inner wall of the mold. This allows the device to be used with different molds to mold automotive components 4, improving the versatility of the device and reducing costs.

[0019] 2. The technical solution of the present invention controls the telescopic component 1 to drive the bottom frame and its upper structure to move upward as a whole, so as to lift each adjusted and locked top rod to be coplanar with the inner wall of the mold at its respective ejection hole. Then, the raw material is put into the mold to form the automotive component 4. After the automotive component 4 is formed, the telescopic component 1 is controlled to extend again to eject the formed automotive component 4 to the top of the mold. Then, the guide rail is controlled to drive the guide seat to slide. During the process, the connecting plate on the side near the vertical plate cancels the contact with the vertical plate and, under the action of the spring 3, drives the connecting plates on both sides to slide to the side relatively away from the mounting frame. Through the meshing of the rack 2 and the gear, the support plates on the gears on both sides move closer to each other and rotate until they rotate to a parallel state that is in contact with the limit frame. At this time, the support plates on both sides will rotate to the top of the lifted automotive component 4. Then, the telescopic component 1 is controlled to shorten, thereby transferring the automotive component 4 to support the support plate. This achieves that the ejection force generated on the automotive component 4 can be evenly distributed when ejecting after forming, avoiding deformation of the automotive component 4 when ejecting after forming, and improving product quality and pass rate.

[0020] 3. The technical solution of the present invention controls the continuous shortening of the telescopic component 1, which drives all the push rods to move below the mold. Subsequently, as the telescopic component 1 continues to move downward, it will drive the rotating plate 2 to rotate continuously and push the push plate to continuously approach the guide seat until it comes into contact with the frame sliding on the guide seat. This will push the frame to move away from the mounting frame and compress the spring 2. During this process, the rack 1 slides and drives the gear ring and the turntable to rotate, so that the mounting table, the support plate, and the automotive component 4 supported on the support plate can rotate 180° to the side away from the mounting frame. This allows for automated unloading of the processed and ejected automotive component 4 by equipment such as a conveyor belt, thereby improving the efficiency of production and processing.

[0034] The following will be combined with the appendix Figure 1 To be continued Figure 11 The technical solutions in the embodiments of the present invention have been clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0035] Example 1:

[0036] like Figures 1-11 As shown, the present invention discloses an automatic part ejection device for automobile molds, including a base 1, an mounting frame 2 installed on the base 1, a mold 3 embedded in the mounting frame 2, a plurality of ejection holes 25 opened at the bottom of the mold 3, a telescopic component 5 installed on the base 1, and a bottom frame 6 installed on the upper output end of the telescopic component 5, a plurality of sets of vertical rods 7 connected to the bottom frame 6, an upper ring 9 connected to the upper end of each set of vertical rods 7, a lower ring 11 coaxially arranged on the lower side of each upper ring 9 and sliding outside the vertical rod 7, an upper rotating ring 14 and a lower rotating ring 15 respectively rotatably fitted inside the upper ring 9 and the lower ring 11, a connecting plate 12 connected to each lower ring 11, and a telescopic component 13 connected between the connecting plate 12 and the bottom frame 6, an upper sliding frame 16 and a lower sliding frame 17 respectively connected along the diameter direction inside the upper rotating ring 14 and the lower rotating ring 15, and a guide rod 18 connected to the lower end of the upper sliding frame 16 and slidingly fitted through the lower sliding frame 17;

[0037] A slide block 19 is slidably connected inside the upper sliding frame 16, and a push rod 23 that slides through the ejector hole 25 is slidably disposed inside the slide block 19. A clamping assembly is provided on the lower sliding frame 17 to clamp and fix the push rod 23. A guide rail 31 is also installed on the base 1, and a guide seat 32 is slidably disposed on the guide rail 31. A turntable 36 is rotatably connected to the guide seat 32. A mounting platform 40 is connected to the upper end of the turntable 36. Gears 41 are rotatably mounted on both sides of the upper end face of the mounting platform 40. Each gear 41 has a... A support plate 42 is connected to support the component 4 formed inside the mold 3. An angle adjustment component is provided on the mounting table 40. The angle adjustment component is used to drive the two support plates 42 to move closer to each other until they are parallel and under the component 4 when the guide seat 32 moves closer to the mold 3. A linkage component is provided on the guide seat 32. The linkage component is used to drive the turntable 36 to rotate simultaneously when the bottom frame 6 moves down and the ejector rod 23 slides out from under the mold 3, so as to rotate the component 4 supported on the support plate 42 to the side away from the mold 3.

[0038] Among them, mold 3 can be a single mold according to the needs of automotive component 4, in order to cooperate with existing molding equipment to mold automotive component 4. However, when it is a mold that requires the upper and lower parts to be combined, mold 3 is only shown as the lower mold.

[0039] The ejection hole 25 through the mold 3 is made according to the structural shape characteristics of the automotive component 4 to be formed, so as to ensure that the formed automotive component 4 can be subjected to uniform force during ejection and avoid deformation.

[0040] The bottom frame 6 is composed of multiple ring structures connected together. Each ring structure is connected to multiple vertical rods 7 in an array. Each upper ring 9 is connected to multiple connecting seats 8 corresponding to the vertical rods 7 arranged in the respective ring structure in an array on its outer side, and is connected to the upper end of the vertical rod 7 through the connecting seats 8. Each lower ring 11 is connected to multiple sleeves 10 corresponding to the vertical rods 7 arranged in the respective ring structure in an array on its outer side, and is slidably fitted on the outer side of the vertical rod 7 through the sleeves 10.

[0041] In the attached diagram of the instruction manual, there are only four annular structures on the bottom frame 6. Therefore, there are also four push rods 23 and four ejector holes 25. At the same time, the number of annular structures, push rods 23 and ejector holes 25 are the same. Therefore, in actual production, different numbers of annular structures, push rods 23 and ejector holes 25 can be set according to the structural shape and other characteristics of automotive component 4.

[0042] The guide rod 18 is connected to both sides of the lower end face of the upper slide frame 16 and slides through both ends of the lower slide frame 17, extending to the bottom of the lower slide frame 17. Bolt 29 is threaded through both sides of the upper ring 9 along the radial direction. Each bolt 29 abuts against the upper ring 9. Bolt 30 is threaded through both sides of the slide block 19 and abuts against the upper slide frame 16.

[0043] The guide rod 18 and the lower sliding frame 17 are slidably connected, so that when the upper rotating ring 14 is rotated, the lower rotating ring 15 can be rotated along with it through the action of the guide rod 18. At the same time, the rotation of the upper rotating ring 14 and the sliding of the slide block 19 within the upper sliding frame 16 allow the push rod 23 sleeved inside the slide block 19 to move to different positions within the area of ​​the upper ring 9. By adjusting the position of the push rod 23 within each upper ring 9, each push rod 23 can be moved appropriately to below different ejection holes 25 and coaxially. The device is designed to facilitate the upward movement of the push rod 23 from the corresponding ejection hole 25 when the telescopic component 5 extends, thereby ejecting the molded automotive component 4. It also ensures that the position of the push rod 23 and the arrangement of the ejection hole 25 can be flexibly adjusted according to the different automotive components 4 when the device is used to eject automotive components 4 of different materials and shapes, thereby improving the versatility of the device. After adjustment, the bolts 29 and 30 can be tightened to ensure the stability of the positions of each upper rotating ring 14 and slide 19.

[0044] Furthermore, since different automotive components 4 have different shapes, when using molds 3 with ejector holes 25 at different positions, each ejector pin 23 needs to be coplanar with the inner wall of the mold 3 to ensure that the automotive component 4 is ejected synchronously during upward movement. This allows different molds 3 to be installed in the mounting frame 2 before production and processing, and after adjusting each ejector pin 23 to be coaxial with the ejector hole 25, the ejector pin 23 can be flexibly adjusted by sliding through the slide block 19 to place the model component in the mold 3. Then, the telescopic component 5 is controlled to extend, driving each ejector pin 23 to move upward, so that the model component can abut against the upper end of each ejector pin 23, causing each ejector pin 23 to slide relative to the slide block 19 in different ways. This ensures that the upper end of each ejector pin 23 is coplanar with the inner wall of the mold 3 at the corresponding ejector hole 25. This allows the ejector pins to seal the ejector hole 25 during the subsequent molding process of the automotive component 4, preventing the surface of the automotive component 4 from being affected by the ejector hole 25 and causing the molding to fail to meet requirements.

[0045] Example 2:

[0046] like Figures 1-11 As shown, the present invention discloses an automatic part ejection device for automobile molds. Compared with Embodiment 1, this embodiment discloses the structure of the clamping component.

[0047] The clamping assembly includes a sleeve frame 20, a slide groove 26, and a clamping seat 27. A circular hole 1901 is provided in the center of the slide seat 19. The top rod 23 slides through the circular hole 1901. The sleeve frame 20 is slidably fitted inside the lower slide frame 17. The slide groove 26 is symmetrically opened on both sides of the bottom of the slide seat 19 and passes through the circular hole 1901 along the diameter direction. The clamping seat 27 is slidably fitted inside the slide groove 26 and extends into the circular hole 1901 to engage with the top rod 23 on both sides. The lower ends of the clamping seats 27 on both sides are rotatably connected to the sleeve frame 20 on the opposite sides.

[0048] After adjusting the position and upper height of each ejector pin 23 to ensure that the upper end of the ejector pin 23 is coplanar with the inner wall of the mold 3 at the corresponding ejection hole 25, the connecting plate 12 and each lower ring 11 are moved down by the telescopic component 2 13, and the lower rotating ring 15 and the sleeve frame 20 are moved down, so as to pull the rotating plate 1 28 to move the two side clamps 27 closer to each other, and clamp the ejector pin 23 to facilitate subsequent multiple ejection operations.

[0049] A slide rod bracket 21 is connected to the lower end face of the slide block 19. A sleeve plate 22 is connected to the lower end of the slide block 19, and the sleeve plate 22 is slidably sleeved on the outside of the slide rod bracket 21. A spring 24 sleeved on the outside of the slide rod bracket 21 is connected between the lower end of the sleeve plate 22 and the lower end of the slide rod bracket 21. The lower end of the slide rod bracket 21 is slidably sleeved in the sleeve frame 20.

[0050] The sliding sleeve 22 and the slide bar bracket 21 ensure the stability of the push rod 23 when it slides up and down to adjust its height. The spring 24 allows each push rod 23 to fit with different positions of the model component under the action of the spring 24, and to achieve coplanarity with the inner wall of the mold 3 at each ejection hole 25.

[0051] Example 3:

[0052] like Figures 1-11 As shown, the present invention discloses an automatic part output device for automobile molds. Compared with Embodiment 2, this embodiment discloses the structure of the angle adjustment component.

[0053] The angle adjustment assembly includes a sleeve rod 43, a connecting plate 44, and a rack 46. There are two sleeve rods 43, which are slidably mounted on the mounting platform 40. There are also two connecting plates 44, which are connected to the two ends of the sleeve rods 43 on both sides of the mounting platform 40. There are also two racks 46, with each end of the rack 46 connected to one side of the connecting plates 44, which are close to each other, and positioned on the side of the gears 41 on both sides. The racks 46 on both sides are far apart from each other and mesh with the gears 41 on both sides. A vertical plate 48 is connected to the side of the base 1 away from the mounting frame 2, and the vertical plate 48 cooperates with the connecting plate 44 to abut.

[0054] The rack 46 is located above the mounting platform 40. A spring 45 is sleeved on the outside of the sleeve rod 43 between the connecting plate 44 on one side and the mounting platform 40. A limit frame 47 is connected to the upper end face of the mounting platform 40. The limit frame 47 is parallel to and abuts against the support plates 42 on both sides for limiting.

[0055] When the control guide seat 32 moves closer to the mounting frame 2, the connecting plate 44 moves away from the vertical plate 48, and under the action of the spring 3 45, it will drive the connecting plates 44 on both sides and the sleeve rod 43 to slide away from the mounting frame 2. Then the rack 2 46 slides, and through the meshing with the gear 41, it drives the support plates 42 on both sides to move closer to each other until they abut against the limit frame 47 and are limited, forming a parallel state, so that each support plate 42 can rotate to be supported by the automotive component 4 pushed out by the push rod 23 above the mold 3.

[0056] Example 4:

[0057] like Figures 1-11 As shown, the present invention discloses an automatic part output device for automobile molds. Compared with Embodiment 3, this embodiment discloses the structure of the linkage component.

[0058] The linkage assembly includes a frame 35, a gear ring 37, a rack 38, a slide bar bracket 30, and a push plate 51. The frame 35 is slidably mounted on the guide seat 32 and sleeved on the outside of the turntable 36. The gear ring 37 is sleeved on the outside of the turntable 36. The rack 38 is connected to the inner wall of one side of the frame 35 and meshes with the gear ring 37. The slide bar bracket 30 is slidably mounted on the mounting frame 2. The push plate 51 is connected to the end of the slide bar bracket 30 near the frame 35 and engages with the frame 35. A rotating plate 2 52 is rotatably connected between the push plate 51 and the bottom frame 6.

[0059] A slide rod bracket 33 is connected to the guide seat 32, and sleeves 34 are connected to both sides of the frame 35. The sleeves 34 are slidably fitted with the slide rod bracket 33 on their respective sides. A spring 39 fitted on the outside of the slide rod bracket 33 is connected between the sleeve 34 and the end of the slide rod bracket 33 away from the mounting frame 2.

[0060] A convex frame 49 is connected to the mounting frame 2, and the slide rod bracket 3 50 slides through the convex frame 49.

[0061] After the automotive component 4 is formed, it is pushed out above the mold 3 by the extension of the telescopic component 5, and the two side support plates 42 are below the pushed-out automotive component 4. As the telescopic component 5 continues to shorten, the automotive component 4 can be transferred to the support plate 42. As the telescopic component 5 continues to shorten, the push plate 51 can be pushed by the rotating plate 52 to move the frame 35 away from the mounting frame 2. During the process, the rack 38 and the gear ring 37 mesh to drive the turntable 36 to rotate, so as to rotate the automotive component 4 supported on the support plate 42 by 180° to the side away from the mounting frame 2 and the mold 3, so as to facilitate the unloading of the formed automotive component 4 by the conveying equipment.

[0062] Working principle:

[0063] The lower molds of different molds 3 or combined molds 3 are installed in the mounting frame 2, and an ejection hole 25 that can penetrate the interior of the mold 3 is opened at the bottom of the mold 3. The opening of the ejection hole 25 is based on the structural shape characteristics of the automotive component 4 to be formed, so as to ensure that the formed automotive component 4 can be subjected to uniform force during ejection and avoid deformation. In specific operation, after the mold 3 is installed on the mounting frame 2, the slide blocks 19 in each upper ring 9 are moved to slide in the upper slide frame 16, and the upper rotating ring 14 in the upper ring 9 is controlled to rotate so that the ejection rod 23 that slides through the slide block 19 can be coaxially aligned with the ejection hole 25 opened on the mold 3. Then, the bolts 1 29 and 2 30 are rotated to ensure that the upper rotating ring 14 and the slide block 19 are in stable position. Then, under the action of the spring 1 24, the sleeve plate 22 will be pushed upward, and the ejector rod 23 will be moved upward through the ejection hole 25 into the interior of the mold 3. Then the model component is placed Inside the mold 3, the model components can abut against the upper ends of each ejector pin 23, making the upper ends of each ejector pin 23 coplanar with the inner wall of the mold 3. This allows the ejector pins 23 to block the ejector holes 25 during the subsequent molding process of the automotive component 4, preventing the surface of the automotive component 4 from being affected by the ejector holes 25 and causing the molding to fail to meet requirements. Then, the telescopic component 2 13 is controlled to move downward, driving the connecting plate 12 to move downward, pulling each lower ring 11 downward, and driving the lower rotating ring 15 and the sleeve 20 downward, so as to pull the rotating plate 1 28 to drive the two side clamping seats 27 to move closer to each other and clamp each ejector pin 23 in this state, so as to ensure that the upper ends of each ejector pin 23 are at different heights above their respective upper rings 9, while also being coplanar with the inner wall of the mold 3. By adjusting the position and height of each ejector pin 23, the device can be matched with different molds 3 for molding and processing automotive components 4, improving the versatility of the device and reducing costs.

[0064] After each ejector pin 23 is adjusted to be coplanar with the inner wall of the mold 3 at each ejection hole 25, the model component can be removed, and the specific automotive component 4 can be produced. During actual production, the telescopic component 5 is controlled to move the bottom frame 6 and its upper structure upwards, so as to lift each adjusted and locked ejector pin 23 to be coplanar with the inner wall of the mold 3 at its respective ejection hole 25. Then, the raw material is placed in the mold 3 to form the automotive component 4. After the automotive component 4 is formed, the telescopic component 5 is controlled to extend again to eject the formed automotive component 4 above the mold 3. Then, the guide rail 31 is controlled to drive the guide seat 32 to slide, so that the upper turntable 36 and the mounting platform 40 move towards the mounting frame 2. During the process, the connecting plate 44 near the vertical plate 48 is canceled. The vertical plate 48 is in contact with the spring 45, and the two connecting plates 44 connected by the sleeve rod 43 slide to the side relatively away from the mounting frame 2. This causes the rack 46 to slide. Through the meshing of the rack 46 and the gear 41, the support plates 42 on the two gears 41 move closer to each other and rotate until they rotate to a parallel state that is in contact with the limit frame 47. At this time, the two support plates 42 will rotate to the top of the lifted automotive component 4. Then, the telescopic component 5 is controlled to shorten, thereby transferring the automotive component 4 to the support plate 42. This ensures that the ejection force generated on the automotive component 4 can be evenly distributed when it is ejected after molding, preventing the automotive component 4 from deforming during ejection and improving product quality and pass rate.

[0065] The telescopic component 5 is continuously shortened, causing all the push rods 23 to move below the mold 3. Subsequently, as the telescopic component 5 continues to move downward, it will cause the rotating plate 52 to rotate continuously and push the push plate 51 to continuously approach the guide seat 32 until it comes into contact with the frame 35 sliding on the guide seat 32. This will push the frame 35 to move away from the mounting frame 2 and compress the spring 39. During this process, the rack 38 slides and causes the gear ring 37 and the turntable 36 to rotate, so that the mounting table 40, the support plate 42, and the automotive component 4 supported on the support plate 42 can rotate 180° to the side away from the mounting frame 2. This allows for automated unloading of the processed and ejected automotive component 4 by conveyor belts and other equipment, improving production efficiency.
