Description

Technical Field

[0001] This invention belongs to the field of automotive component molding and processing technology, and in particular relates to a molding device for irregular curved surfaces of automotive fairings. Background Technology

[0002] Automotive fairings are key components for optimizing vehicle aerodynamics. Their shape must strictly conform to the overall streamlined design of the car body, and they generally adopt irregular curved surface structures with continuous transitions of multiple curvatures. Some products also integrate complex structures such as crisscrossing reinforcing fins and inwardly recessed assembly connections on their inner walls. Currently, the mass production of irregular curved automotive fairings mainly relies on compression molding. This process involves placing the raw material in a mold cavity at a molding temperature, and then completing the molding and curing process by closing the mold and applying pressure. It has advantages such as high molding efficiency, good product consistency, and excellent compatibility with composite material processing.

[0003] In compression molding, the demolding process is a core step that determines product molding quality, production continuity, and mold lifespan. Most existing demolding structures adopt a single fixed direction design, with vertical demolding being the main form. The core of this is to use ejection mechanisms such as ejector rods to eject the molded guide shield from the mold core or mold groove along a fixed vertical direction. The multi-curvature continuous structure of the irregular curved surface guide shield makes it fit tightly with the mold cavity and has a large contact area. After compression molding, the material cools and shrinks, which will generate a strong clamping force. However, the ejection force in a single fixed direction cannot be evenly distributed along the curved surface contour, resulting in an imbalance of force on the guide shield during the ejection process. This easily leads to molding defects such as surface warping, local depressions, and surface scratches, reducing the product qualification rate and increasing production costs. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that existing demolding methods use a single ejection method, which results in the ejection force not being evenly distributed along the curved surface contour, leading to an imbalance of force on the fairing during the ejection process and easily causing molding defects such as surface warping, local depressions, and surface scratches. Therefore, this invention proposes a molding device for irregular curved surfaces of automotive fairings.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A molding apparatus for irregular curved surfaces of automotive fairings includes: a base, a molding frame mounted on the base, an electric hydraulic cylinder mounted on the top of the molding frame, a top mold fixedly mounted at the bottom end of the electric hydraulic cylinder, a bottom mold located directly below the top mold, a sliding support assembly on the outside of the bottom mold, a pushing assembly fixedly mounted behind the sliding support assembly, the pushing assembly being mounted on the rear side of the base, and rotating flipping assemblies extending through both sides of the sliding support assembly. The opposite ends of the two flipping assemblies are respectively fixedly connected to both sides of the bottom mold, and a guide is slidably connected to the bottom of the flipping assembly. The base has grooves corresponding to the positions of two guide components. The guide components are fixedly installed in the grooves. The front ends of the two guide components pass through the grooves and are fixed with a fixing frame. The fixing frame is fixed to the front side of the base. The bottom of the bottom mold has a transmission component that rotates through it. The two ends of the transmission component are respectively connected to the two sides inside the sliding support component. Several striking components are connected to the outside of the transmission component. The tops of the striking components overlap with the bottom of the bottom mold. The bottom of the bottom mold is fixedly connected to a bracket, and the bottom ends of the striking components slide through the bracket.

[0007] As a further description of the above technical solution:

[0008] The sliding support assembly includes a support frame, with toothed rings fixedly connected to both sides inside the support frame, the bottom mold located inside the support frame, and the rear of the support frame connected to the pushing assembly.

[0009] As a further description of the above technical solution:

[0010] The pushing component includes a limiting baffle, which is fixed on the base and overlaps with the rear of the support frame. Electric push rods slide through both sides of the limiting baffle, and the other end of the electric push rods is fixedly installed at the rear of the base.

[0011] As a further description of the above technical solution:

[0012] The flipping assembly includes a deflecting wheel with several grooves on one side of its outer surface. Sliding plates are fixed to the top and bottom of the deflecting wheel, and the sides of the two sliding plates that are far apart from each other are flat. An arc-shaped groove on one side of the sliding plate is connected to one of the grooves. A rotating shaft is fixed to the middle of the deflecting wheel. The rotating shaft rotates on one side of the support frame through a bushing, and one end of the rotating shaft passes through the support frame and is fixedly connected to one side of the bottom mold.

[0013] As a further description of the above technical solution:

[0014] The guide assembly includes a support slide rail, which is fixedly connected in the groove. One end of each of the two support slide rails passes through the groove and is fixed to the fixing frame. The sliding plate at the bottom of the deflection wheel is slidably connected inside the support slide rail. Several sliding pillars are fixed on one side of the inner wall of the support slide rail corresponding to the position of the deflection wheel. The bottom of the support slide rail is provided with clearance holes corresponding to the positions of the sliding pillars.

[0015] As a further description of the above technical solution:

[0016] The transmission assembly includes a connecting shaft, the two ends of which are rotatably connected to the bottom of the bottom mold via bushings. A transmission gear is fixed at each end of the connecting shaft, and the transmission gear meshes with a gear ring. The gear ring is coaxial with the rotating shaft. Several sets of half gears are fixedly connected to the outside of the connecting shaft, and each set of half gears consists of two half gears.

[0017] As a further description of the above technical solution:

[0018] The striking assembly includes a crossbar with an L-shaped design, and a number of teeth are fixed on one side of the vertical section of the crossbar, the teeth corresponding to the positions of the half gears.

[0019] As a further description of the above technical solution:

[0020] A striking rod is fixedly connected to the crossbar, and the striking rod overlaps the bottom of the bottom mold. Several sliding rods are fixed to the bottom of the crossbar, and the bottom end of the sliding rod slides through the bracket. A spring is sleeved on the sliding rod, and the two ends of the spring are fixed between the crossbar and the bracket.

[0021] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. In this invention, the bottom mold is synchronously rotated by a rotating shaft, rotating 180 degrees. This, combined with the gravity of the molded part, assists in demolding and optimizes the demolding posture. During the rotation of the bottom mold by the deflection wheel, the transmission assembly at the bottom can revolve around the axis of the rotating shaft. Since the transmission gears at both ends of the connecting shaft are always meshed with the gear ring inside the support frame, the gear ring exerts a force on the transmission gears, causing the connecting shaft to rotate around its own axis. When the connecting shaft rotates, it drives several sets of externally fixed half-gears to rotate synchronously. During the rotation of the half-gears, their tooth surfaces periodically mesh and separate from the teeth on the crossbar of the striking assembly. When the half-gears... When meshing with the teeth, the half gear exerts a downward force, causing the crossbar to move away from the bottom mold. The crossbar compresses the spring, simultaneously causing the striking rod to move away from the bottom mold. When the half gear separates from the teeth, the spring force returns to its original position, pushing the crossbar to move in the opposite direction and causing the striking rod to quickly strike the bottom of the bottom mold. Through the continuous rotation of the half gear, the striking component achieves high-frequency and uniform striking of the bottom of the bottom mold. The resulting vibration is transmitted to the inside of the bottom mold cavity, effectively offsetting the clamping force caused by cooling and shrinkage after the guide shroud is formed. This allows the guide shroud to gradually separate from the bottom mold cavity, avoiding defects such as surface scratches and structural damage caused by manual peeling, and improving the product qualification rate. 2. In this invention, the deflection wheel of the flipping component moves synchronously with the support frame, and the sliding plate at its bottom slides along the support rail of the guide component. The sliding column on the inner wall of the support rail gradually slides from the arc groove on one side of the sliding plate into the rolling groove of the deflection wheel. Since the sliding column is fixed on the support rail, as the support frame continues to move, the sliding column generates a lateral force on the deflection wheel, causing the deflection wheel to rotate around the rotation axis. When the deflection wheel rotates, it drives the bottom mold to flip synchronously through the rotation axis. The flipping angle is controlled by the moving distance of the support frame. The greater the moving distance of the support frame, the greater the displacement of the sliding column in the arc groove, and the greater the flipping angle of the deflection wheel. Finally, the bottom mold is flipped to the optimal angle for demolding the irregular curved surface guide hood, so that the normal direction of the irregular curved surface of the guide hood tends to be consistent with the direction of the demolding force, thereby improving the demolding effect.

[0031] 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.

[0032] In its specific implementation, such as Figures 1-7 The present invention provides a technical solution:

[0033] A molding apparatus for irregular curved surfaces of automotive fairings includes: a base 1, a molding frame 2 mounted on the base 1, an electric hydraulic cylinder 3 mounted on the top of the molding frame 2, a top mold 4 fixedly mounted at the bottom end of the electric hydraulic cylinder 3, a bottom mold 5 located directly below the top mold 4, a sliding support assembly 6 externally mounted on the bottom mold 5, the sliding support assembly 6 including a support frame 601, toothed rings 602 fixedly connected to both sides inside the support frame 601, the bottom mold 5 located inside the support frame 601, and a pushing assembly 7 connected to the rear of the support frame 601; the pushing assembly 7 is fixedly mounted to the rear of the sliding support assembly 6 and is mounted on the base 1. The rear push assembly 7 includes a limiting baffle 701, which is fixed on the base 1 and overlaps with the rear of the support frame 601. Electric push rods 702 slide through both sides of the limiting baffle 701, and the other end of the electric push rods 702 is fixedly installed at the rear of the base 1. The electric push rods 702 extend and push the support frame 601 of the sliding support assembly 6 to slide forward along the base 1. The support frame 601 drives the bottom mold 5, the flipping assembly 8, the transmission assembly 13, and the striking assembly 14 to move forward synchronously, so that the bottom mold 5 is separated from the pressing working area of ​​the upper mold, which facilitates demolding and improves the operational safety of demolding.

[0034] A rotating flipping assembly 8 is rotatably mounted on both sides of the sliding support assembly 6. The opposite ends of the two flipping assemblies 8 are fixedly connected to the two sides of the bottom mold 5. Each flipping assembly 8 includes a deflecting wheel 801. Several grooves 802 are formed on one side of the deflecting wheel 801. Sliding plates 803 are fixed to the top and bottom of the deflecting wheel 801. The sides of the two sliding plates 803 that are far apart from each other are flat. An arc-shaped groove on one side of each sliding plate 803 communicates with one of the grooves 802. A rotating shaft 804 is fixed to the middle of the deflecting wheel 801. The external surface of the rotating shaft 804 is open to… The bushing rotates on one side of the support frame 601, and one end of the rotating shaft 804 passes through the support frame 601 and is fixedly connected to one side of the bottom mold 5. The bottom of the flipping component 8 is slidably connected to the guide component 10, which includes a support slide rail 101. The sliding plate 803 at the bottom of the deflection wheel 801 slides along the support slide rail 101 of the guide component 10. The support slide rail 101 of the guide component 10 always guides and limits the sliding plate 803 of the flipping component 8, ensuring that the bottom mold 5 flips smoothly and avoiding defects in the formation of the flow guide due to flipping offset.

[0035] The base 1 has grooves 9 corresponding to the positions of the two guide components 10. The guide components 10 are fixedly installed in the grooves 9. The front ends of the two guide components 10 pass through the grooves 9 and are fixed with a fixing frame 11. The fixing frame 11 is fixed to the front side of the base 1. The support slide rails 101 are fixedly connected in the grooves 9. One end of the two support slide rails 101 passes through the grooves 9 and is fixed with the fixing frame 11. The sliding plate 803 at the bottom of the deflection wheel 801 is slidably connected to the inside of the support slide rails 101. Several sliding posts 102 are fixed on one side of the inner wall of the support slide rail 101 corresponding to the position of the deflection wheel 801. The bottom of the support slide rail 101 has clearance holes 103 corresponding to the positions of the sliding posts 102. Gradually, the slide column 102 slides from the arc groove on one side of the sliding plate 803 into the rolling groove 802 of the deflection wheel 801. Since the slide column 102 is fixed on the support slide rail 101, as the support frame 601 continues to move, the slide column 102 generates a lateral force on the deflection wheel 801, causing the deflection wheel 801 to rotate around the rotation axis 804. When the deflection wheel 801 rotates, it drives the bottom mold 5 to rotate synchronously through the rotation axis 804. The rotation angle is controlled by the moving distance of the support frame 601. The greater the moving distance of the support frame 601, the greater the displacement of the slide column 102 in the arc groove, and the greater the rotation angle of the deflection wheel 801. Finally, the bottom mold 5 is rotated to the optimal angle to adapt to the demolding of the irregular curved surface guide hood, so that the normal direction of the irregular curved surface of the guide hood tends to be consistent with the direction of the demolding force.

[0036] When the deflection wheel 801 continues to rotate, it can pass over the clearance hole 103, so that the sliding plate 803 at the other relative position of the deflection wheel 801 is vertically downward and re-contacts the inside of the support rail 101, thereby improving the stability of the support rail 101 in supporting the sliding plate 803.

[0037] A transmission assembly 13 is rotatably connected to the bottom of the bottom mold 5. Both ends of the transmission assembly 13 are connected to the two sides inside the sliding support assembly 6. The transmission assembly 13 includes a connecting shaft 131, whose two ends are rotatably connected to the bottom of the bottom mold 5 via bushings. Transmission gears 132 are fixed to both ends of the connecting shaft 131, and these gears 132 mesh with a gear ring 602. The gear ring 602 is coaxial with the rotating shaft 804. Several sets of half-gears 133 are fixedly connected to the outside of the connecting shaft 131, with two half-gears in each set. The deflecting wheel 801... During the flipping process of the bottom mold 5, the transmission component 13 at the bottom can be driven to revolve around the axis of the rotating shaft 804. Since the transmission gears 132 at both ends of the connecting shaft 131 are always meshed with the gear ring 602 in the support frame 601, and the gear ring 602 is coaxial with the rotating shaft 804, as the bottom mold 5 flips, the gear ring 602 exerts a force on the transmission gear 132, causing the connecting shaft 131 to rotate around its own axis. When the connecting shaft 131 rotates, it drives several sets of half gears 133 fixed outside to rotate synchronously, which facilitates the half gears 133 to drive the striking component 14 to work synchronously.

[0038] The transmission assembly 13 is externally connected to several striking components 14. The tops of the striking components 14 overlap with the bottom of the bottom mold 5. A bracket 12 is fixedly connected to the bottom of the bottom mold 5, and the bottom ends of the striking components 14 slide through the bracket 12. Each striking component 14 includes a crossbar 141, which is L-shaped. Several teeth 142 are fixed on one side of the vertical section of the crossbar 141, and the teeth 142 correspond to the positions of the half gears 133. A striking rod 143 is fixedly connected to the crossbar 141 and overlaps with the bottom of the bottom mold 5. Several sliding rods 144 are fixed to the bottom of the crossbar 141, and the bottom ends of the sliding rods 144 slide through the bracket 12. A spring 145 is attached to the outer sleeve, with both ends of the spring 145 fixed between the crossbar 141 and the bracket 12. When the half gear 133 meshes with the teeth 142, it generates a downward force on the half gear 133, causing the crossbar 141 to move away from the bottom mold 5. The crossbar 141 compresses the spring 145, and at the same time, it causes the striking rod 143 to move away from the bottom mold 5. When the half gear 133 separates from the teeth 142, the elastic force of the spring 145 returns to its original state, pushing the crossbar 141 to move in the opposite direction, and causing the striking rod 143 to quickly strike the bottom of the bottom mold 5. Through the continuous rotation of the half gear 133, the striking component 14 achieves high-frequency and uniform striking of the bottom of the bottom mold 5. The generated vibration is transmitted to the cavity of the bottom mold 5, which helps the demolding of the molded part.

[0039] Working principle:

[0040] During compression molding, the operator evenly spreads the material for the guide shield molding inside the cavity of the bottom mold 5, ensuring that the material covers all irregular curved areas of the cavity. Then, the electric hydraulic cylinder 3 is activated, which drives the top mold 4 to move downward in the vertical direction until the top mold 4 and the bottom mold 5 are precisely closed. The top mold 4 applies stable pressure to the material inside the bottom mold 5. At the same time, in conjunction with the mold's preset temperature control, the material, under the combined action of pressure and temperature, conforms to the irregular curved surface of the cavity of the bottom mold 5 to complete molding and curing. After the molding process is completed, the electric hydraulic cylinder 3 drives the top mold 4 to return to its original position in the vertical direction, separating it from the bottom mold 5, thus completing the compression molding process.

[0041] After the compression molding is completed, the demolding preparation stage begins. The electric push rod 702 of the push assembly 7 is activated, and the electric push rod 702 extends, pushing the support frame 601 of the sliding support assembly 6 to slide forward along the machine base 1. The support frame 601 drives the bottom mold 5, the flipping assembly 8, the transmission assembly 13, and the striking assembly 14 to move forward synchronously. During this process, the deflection wheel 801 of the flipping assembly 8 moves synchronously with the support frame 601, and the sliding plate 803 at its bottom slides along the support slide rail 101 of the guide assembly 10. The sliding column 102 on the inner wall of the support slide rail 101 gradually slides from the arc groove on one side of the sliding plate 803 into the rolling groove 802 of the deflection wheel 801. Since the sliding column 102 is fixed on the support slide rail 101, as the support frame 601 continues to move, the sliding column 102 generates a lateral force on the deflection wheel 801, causing the deflection wheel 801 to rotate around the rotation axis 804.

[0042] When the deflection wheel 801 rotates, it drives the bottom mold 5 to rotate synchronously through the rotating shaft 804. The rotation angle is controlled by the moving distance of the support frame 601. The greater the moving distance of the support frame 601, the greater the displacement of the slide column 102 in the arc groove, and the greater the rotation angle of the deflection wheel 801. Finally, the bottom mold 5 is rotated to the optimal angle for demolding the irregular curved surface guide hood, so that the normal direction of the irregular curved surface of the guide hood tends to be consistent with the direction of the demolding force. When the deflection wheel 801 continues to rotate, it can pass through the clearance hole 103, so that the sliding plate 803 of the other relative position of the deflection wheel 801 is vertically downward and re-contacts the inside of the support slide rail 101. At this time, the deflection wheel 801 drives the bottom mold 5 to rotate 180 degrees through the rotating shaft 804, which, together with the gravity of the molded part, assists in demolding, thereby further optimizing the demolding posture.

[0043] During the process of the deflection wheel 801 driving the bottom mold 5 to rotate, it can drive the transmission component 13 at the bottom to revolve around the axis of the rotating shaft 804. Since the transmission gears 132 at both ends of the connecting shaft 131 are always meshed with the gear ring 602 in the support frame 601, and the gear ring 602 is coaxial with the rotating shaft 804, as the bottom mold 5 rotates, the gear ring 602 exerts a force on the transmission gear 132, causing the connecting shaft 131 to rotate around its own axis. When the connecting shaft 131 rotates, it drives several sets of half gears 133 fixed outside it to rotate synchronously. During the rotation of the half gears 133, their tooth surfaces periodically mesh and separate from the teeth 142 on the crossbar 141 of the striking component 14.

[0044] When the half gear 133 meshes with the tooth 142, it generates a downward force on the half gear 133, which drives the crossbar 141 away from the bottom mold 5. The crossbar 141 compresses the spring 145 and simultaneously drives the striking rod 143 away from the bottom mold 5. When the half gear 133 separates from the tooth 142, the spring force of the spring 145 returns to its original state, pushing the crossbar 141 to move in the opposite direction and driving the striking rod 143 to quickly strike the bottom of the bottom mold 5. Through the continuous rotation of the half gear 133, the striking component 14 achieves high-frequency and uniform striking of the bottom of the bottom mold 5. The resulting vibration is transmitted to the cavity of the bottom mold 5, causing the guide cover to gradually separate from the cavity of the bottom mold 5.

[0045] With the continuous striking of the striking component 14 and the slow forward movement of the sliding support component 6, the guide shield smoothly detaches from the cavity of the bottom mold 5 under the combined action of gravity and vibration, completing the demolding operation and subsequent processing. After demolding, the electric push rod 702 of the pushing component 7 is activated. The electric push rod 702 retracts, driving the support frame 601 of the sliding support component 6 to move backward along the machine base 1. The support frame 601 drives the bottom mold 5, the flipping component 8, the transmission component 13, and the striking component 14 to synchronously reset backward. During this process, the sliding plate 803 at the bottom of the deflection wheel 801 moves along... The support slide rail 101 slides backward, and the slide column 102 slides back into the rolling groove 802 through the arc groove on one side of the sliding plate 803, driving the deflection wheel 801 to rotate in the opposite direction, so that the bottom mold 5 flips to the initial horizontal state. At the same time, the transmission gear 132 moves in the opposite direction with the support frame 601, driving the connecting shaft 131 and the half gear 133 to rotate in the opposite direction. The striking component 14 gradually stops striking and returns to the initial overlapping state under the action of the spring 145. When the support frame 601 and the limit baffle 701 are tightly overlapped again, the electric push rod 702 stops retracting and waits for the next molding and demolding operation.
