Description

Technical Field

[0001] This utility model relates to the field of automotive plastic parts manufacturing technology, and in particular to a shaping equipment for automotive plastic parts. Background Technology

[0002] Automotive plastic parts are an indispensable component of modern automobile manufacturing, with applications spanning multiple areas including interior and exterior trim, functional components, and more. Examples include dashboards, door panels, seats, headliners, engine hoods, and valve covers. The production of these plastic parts requires injection molding, where molten plastic is injected into a mold cavity and, after cooling and solidification, forms a product of a specific shape.

[0003] During injection molding, the flow and cooling process of the melt generates internal stress in plastic parts. After demolding, the stress release can cause slight deformation of the parts, which needs to be corrected by shaping equipment. For example, shaping equipment with prior art publication numbers CN218171372U and CN214239519U can be used to shape automotive plastic parts.

[0004] However, in practical use, the existing technology is not convenient for shaping different plastic parts or different positions on the same plastic part due to the fixed shape and size of the shaping plate, which has limitations. Moreover, plastic debris is generated during the shaping process. Under the action of impact, the plastic debris is thrown outward, which can easily contaminate the workbench and increase the cleaning intensity for personnel. Utility Model Content

[0005] To address the limitations of existing shaping equipment mentioned in the background section, and the problems that plastic debris generated during shaping easily contaminates the workbench and increases the workload of cleaning personnel, this utility model provides the following technical solution:

[0006] A shaping device for automotive plastic parts includes a frame, a bracket fixed to the rear top of the frame, a drive device fixed to the front end of the bracket, and a shaping device on the drive device. The shaping device includes a threaded cylinder, and the bottom of the threaded cylinder is provided with a shaper component that is easy to replace, so as to shape different plastic parts or different positions on the same plastic part, and has a wide range of applications.

[0007] The threaded cylinder is equipped with a dust collection component on its exterior. The dust collection component moves with the shaping component and is used to absorb and clean the plastic debris generated during the shaping process of the shaping component, so as to prevent the plastic debris from contaminating the workbench and avoid increasing the cleaning intensity for personnel.

[0008] Furthermore, the shaping assembly includes a support block and a shaping head fixed to the bottom of the support block. A threaded inner rod is fixed to the top of the support block. The threaded inner rod is located inside a threaded cylinder, and the threaded inner rod and the threaded cylinder are connected by threads, which facilitates the disassembly of the shaping head for replacement.

[0009] Furthermore, the dust collection assembly includes a hollow plate disposed outside the threaded cylinder, and the bottom end of the hollow plate has a plurality of dust collection holes communicating with the inner cavity of the hollow plate.

[0010] Furthermore, a negative pressure suction tube is connected to one side of the top of the hollow board. The negative pressure suction tube is connected to a negative pressure device to generate negative pressure in the hollow board to absorb plastic debris, prevent plastic debris from contaminating the workbench, and avoid increasing the cleaning intensity for personnel.

[0011] Furthermore, a sleeve is fixed through the center of the hollow plate. The sleeve is fitted onto the outer wall of the threaded cylinder and is slidably connected to the threaded cylinder. This facilitates the adjustment of the height of the hollow plate, ensuring that the hollow plate is always above the plastic part and preventing the hollow plate from obstructing the shaping of the plastic part.

[0012] Furthermore, limit blocks are fixed at the top and bottom of the sleeve on the outside of the threaded cylinder, and locking bolts for fixing the sleeve and the threaded cylinder are threadedly connected to the outside of the sleeve, and the locking bolts are located at the top of the hollow plate.

[0013] Furthermore, the driving device includes a linear motor module fixed to the front end of the bracket, a support rod fixed on the linear motor module, a threaded cylinder located at the bottom end of the support rod, and an electric push rod fixed to the top end of the support rod and the top end of the threaded cylinder, which is used to drive the shaping device to lift and press and shape the plastic part at the position that needs to be shaped, thereby correcting the shape of the plastic part.

[0014] Furthermore, the top two sides of the frame are equipped with clamps for fixing automotive plastic parts, and both sets of clamps are located below the shaping device; a ball screw slide for adjusting the distance between the two sets of clamps is fixed on the front side of the top of the frame, and a slide rail for the two sets of clamps is fixed on the rear side of the top of the frame, so that plastic parts of different sizes can be fixed through the clamps, so as to ensure stable shaping work in the future.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. The shaping assembly is driven up and down by the drive device, so that the shaping head extrudes and shapes the plastic part at the position that needs to be shaped, thereby correcting the shape of the plastic part; at the same time, the shaping head has different shapes and sizes according to the shape of the plastic part, which makes it easy to disassemble and replace the shaping head, thus making it easy to shape different plastic parts or different positions on the same plastic part, with a wide range of applications.

[0017] 2. The dust collection component is located near the top of the shaping component. When the shaping component is in operation, the dust collection component generates negative pressure to suck out and collect the plastic debris generated by the impact during the shaping process, preventing plastic debris from contaminating the workbench and avoiding increasing the cleaning intensity for personnel.

[0028] The preferred embodiments of this utility model are described in detail below, and a clear and complete explanation is given in conjunction with the accompanying drawings.

[0029] Please see Figure 1 As shown, this utility model provides a shaping device for automotive plastic parts, including a frame 10. A bracket 20 is fixed to the rear side of the top of the frame 10. Clamps 50 are provided on both sides of the top of the frame 10. A ball screw slide 60 for adjusting the distance between the two sets of clamps 50 is fixed to the front side of the top of the frame 10, and a slide rail for facilitating the sliding of the two sets of clamps 50 is fixed to the rear side of the top of the frame 10. The ball screw slide 60 uses the FSL60 series high-precision ball screw slide module from Foyu Technology, which is a high-efficiency and high-precision linear motion device. Its working principle is based on the transmission method of ball screws. A ball screw is a transmission element that converts rotational motion into linear motion. Through the rotation of the screw, the balls are driven to circulate between the screw and the nut, thereby realizing the linear motion of the nut. It is widely used in various automated equipment, precision instruments and robots.

[0030] After the plastic parts to be shaped are placed on the frame 10, the positions of the two sets of clamps 50 are adjusted by the ball screw slide 60 and then the plastic parts are fixed, which makes it easy to fix plastic parts of different sizes so that the subsequent shaping work can be carried out stably.

[0031] Next, as Figures 1-5 As shown, a drive device 30 is fixed at the front end of the bracket 20, and a shaping device 40 is provided on the drive device 30. Two sets of clamps 50 are located below the shaping device 40. The drive device 30 includes a linear motor module 31 fixed to the front end of the bracket 20. The linear motor module 31 is a standard type of the MISUMI economic linear motor module 6 series, such as E-RAM6-S-40-NN, which is suitable for high-precision automated equipment. A support rod 32 is fixed on the linear motor module 31. A threaded cylinder 41 is located at the bottom end of the support rod 32, and an electric push rod 33 is fixed at the top end of the support rod 32 and the top end of the threaded cylinder 41. This electric push rod 33 is used to drive the shaping device 40 to lift and lower. The electric push rod 33 is a JC35FA2 electric push rod from Jiechang Intelligent, which has a high load capacity and is widely used in AGVs, material handling, elevated platforms, wheelchair lifts / disability assistance equipment, agricultural vehicles, construction machinery, road construction machinery, integrated automation, assembly lines and other fields.

[0032] Specifically, the shaping device 40 includes a threaded cylinder 41, and a shaping component 42 is provided at the bottom of the threaded cylinder 41. The shaping component 42 includes a support block 422 and a shaping head 421 fixed to the bottom end of the support block 422. A threaded inner rod 423 is fixed at the top end of the support block 422. The threaded inner rod 423 is located inside the threaded cylinder 41 and is connected to the threaded cylinder 41 by threads.

[0033] After the plastic part is fixed to the bottom of the shaping component 42 by the clamp 50, the horizontal position of the shaping component 42 is adjusted by the linear motor module 31 so that the shaping component 42 is above the position on the plastic that needs to be shaped. Then, the shaping component 42 is driven to move up and down by the electric push rod 33 so that the shaping head 421 squeezes and shapes the position on the plastic part that needs to be shaped, thereby correcting the shape of the plastic part.

[0034] Meanwhile, the shaping head 421 has different shapes and sizes according to the plastic parts. The shaping head 421 is connected to the threaded cylinder 41 by a thread, which makes it easy to disassemble the shaping head 421 for replacement. This makes it easy to shape different plastic parts or different positions on the same plastic part, and has a wide range of applications.

[0035] Furthermore, a dust collection component 43 is provided outside the threaded cylinder 41. The dust collection component 43 moves with the shaping component 42 and is used to absorb and clean the plastic debris generated during the shaping process of the shaping component 42. Specifically, the dust collection component 43 includes a hollow plate 431 located outside the threaded cylinder 41. The bottom end of the hollow plate 431 has multiple dust collection holes communicating with the inner cavity of the hollow plate 431. A negative pressure suction pipe 434 is connected to one side of the top end of the hollow plate 431. The negative pressure suction pipe 434 is connected to a negative pressure device. The negative pressure device is an industrial negative pressure dust collector PT100. PT100 is a rectangular dust collector suitable for vacuuming in robot welding, automated equipment, automatic production lines, PCB, precision laser engraving and cutting, etc.

[0036] The hollow plate 431 is located near the top of the shaping component 42. When the shaping component 42 is performing shaping work, the negative pressure device creates negative pressure inside the hollow plate 431. Plastic debris generated by the impact during shaping is sucked into the hollow plate 431 and then discharged through the negative pressure suction pipe 434, preventing plastic debris from contaminating the workbench and avoiding increasing the cleaning intensity for personnel.

[0037] Furthermore, such as Figure 2 and Figure 4 As shown, a sleeve 432 is fixed through the center of the hollow plate 431. The sleeve 432 is sleeved on the outer wall of the threaded cylinder 41 and the sleeve 432 is slidably connected to the threaded cylinder 41. Limiting blocks 44 are fixed at the top and bottom of the sleeve 432 on the outside of the threaded cylinder 41. Locking bolts 433 for fixing the sleeve 432 and the threaded cylinder 41 are threadedly connected to the outside of the sleeve 432, and the locking bolts 433 are located at the top of the hollow plate 431.

[0038] Slide the sleeve 432 along the threaded cylinder 41 to drive the hollow plate 431 to move up and down. Then tighten the locking bolt 433 to fix the sleeve 432 and the hollow plate 431, so as to make it easy to adjust the height of the hollow plate 431. This makes it easy to adjust the height of the hollow plate 431 according to the shape of the plastic part, so that the hollow plate 431 is always above the plastic part and avoids the hollow plate 431 from obstructing the shaping work of the plastic part.

[0039] Based on the above description and accompanying drawings, those skilled in the art can understand and implement this utility model. Furthermore, any non-creative modifications made to this utility model by those skilled in the art without inventive effort are still within the protection scope of this utility model.
