Description

Technical Field

[0001] This utility model belongs to the field of automotive parts manufacturing and processing technology, and specifically relates to an automatic unloading device for stamping in automotive parts manufacturing and processing. Background Technology

[0002] Against the backdrop of the rapid development of the automobile manufacturing industry, stamping, as a core process in the production of automotive parts, plays an important role in transforming sheet metal into components that meet design standards. The automatic feeding stamping device for automotive parts disclosed in Chinese Patent No. CN221289166U achieves automatic loading and unloading of parts through moving components and automatic feeding components, which improves operational safety and processing continuity to a certain extent. However, the technical bottleneck in the demolding process of this device has become a key factor restricting the efficient production of automotive parts.

[0003] From a cost perspective, existing stamping equipment typically requires an independent demolding drive structure. Common hydraulic demolding systems require complex components such as oil pumps, hydraulic cylinders, and control valves, while pneumatic demolding relies on air compressors, cylinders, and air pipelines. These specialized structures not only increase the initial purchase cost of the equipment, but also require professional technicians to regularly calibrate the system and troubleshoot problems during maintenance. In addition, the complex demolding structure occupies a lot of installation space, which reduces the compactness of the production line layout and indirectly increases the site usage cost.

[0004] In terms of ease of operation and efficiency, the lack of automation in existing demolding methods is particularly prominent. Most devices require manual intervention to assist in demolding, such as manually operating the ejector rod to separate the stamped part from the mold, or manually peeling off the adhered workpiece with tools. These operations are not only time-consuming, but also require operators to be in close contact with the mold, posing safety hazards. Some semi-automatic demolding solutions that rely on the cooperation of sensors and robotic arms often fail to demold or damage the workpiece due to differences in mold structure and deformation of stamped parts, requiring machine shutdown to adjust parameters, which seriously affects the continuity of production. Manual demolding significantly extends the processing cycle of a single piece, making it difficult to meet the production requirements of the modern automotive manufacturing industry for "high capacity and short delivery time". Utility Model Content

[0005] In view of the problems mentioned in the background art, the purpose of this utility model is to provide an automatic unloading device for stamping in the production and processing of automotive parts, so as to solve the problem that the overall demolding is cumbersome and inconvenient during the application of the prior art.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] An automatic unloading device for stamping in the production and processing of automotive parts includes a base, with support legs fixedly connected to the four corners of the top of the base, a top seat fixedly installed on the top of the support legs, a frame fixedly installed on the top of the top seat, a hydraulic cylinder fixedly installed on the top of the frame, an upper mold fixedly installed through the output end of the hydraulic cylinder through the frame, a lower mold fixedly installed in the middle of the top seat, an unloading mechanism fixedly installed on one side of the frame, and a demolding mechanism fixedly installed on the back of the upper mold, with the top of the demolding mechanism penetrating through the top seat and disposed inside the lower mold.

[0008] The demolding mechanism includes a connecting rod, which is fixedly installed on the rear side of the upper mold. A base frame is fixedly connected to the bottom of the connecting rod, and demolding ejector rods are fixedly installed at the four corners of the top of the base frame. The ends of the demolding ejector rods penetrate the top seat and the upper mold.

[0009] Furthermore, the end of the ejector pin passes through the top seat and is fixedly connected to the ejector plate, which is movable inside the lower mold.

[0010] Furthermore, the feeding mechanism includes a side rail, which is fixedly installed on the upper side of one side of the frame. A second motor is fixedly installed at the rear end of the frame. A lead screw is fixedly installed through the side rail at the output end of the second motor. The lead screw is rotatably connected to the inside of the frame. A slider is threadedly connected to the outer surface of the lead screw. A pusher is fixedly installed on one side of the slider.

[0011] Furthermore, the pusher includes a connecting rod, which is fixedly connected to the inner side of the slider. The front end of the slider is fixedly mounted with the connecting rod, and the bottom of the connecting rod is fixedly mounted with a pusher plate, which is located on the rear side of the lower mold.

[0012] Furthermore, a guide plate is fixedly installed at the center of the front end of the top seat, and the guide plate is inclined as a whole.

[0013] Furthermore, a conveyor frame is fixedly installed at the top front end of the base, and a conveyor belt is rotatably connected inside the conveyor frame. A first motor is fixedly connected to one front end of the conveyor frame, and the output end of the first motor passes through the conveyor frame and is connected to the rotating shaft inside the conveyor belt.

[0014] Furthermore, the internal cavity cross-sectional shape of the side rail is set to a convex shape, the side shape of the slider is also set to a convex shape, and a wear-resistant pad is fixedly connected to the outer surface of the slider.

[0015] In summary, the present invention has the following main advantages:

[0016] First, during the stamping operation, this automatic unloading device uses the hydraulic cylinder of the top frame as power to drive the upper mold to move vertically. The unique feature is that the demolding function is integrated into the lifting process of the upper mold. When the hydraulic cylinder drives the upper mold to rise, the connecting rod, base frame, and demolding ejector rod of the demolding mechanism work together to push the demolding plate to eject the formed product from the lower mold. This design uses the movement of the stamping equipment itself to complete the demolding, without the need for an additional independent demolding system, simplifying the mechanical structure and reducing equipment procurement and maintenance costs.

[0017] Secondly, after demolding is completed during the application of this equipment, the unloading mechanism is immediately started. The second motor drives the lead screw to rotate, and the convex slider slides smoothly along the side rail with the same cross section through the thread transmission. The wear-resistant pad ensures its smooth operation. The slider drives the push frame to move forward, and the push plate pushes the product out. It slides to the conveyor belt through the inclined guide plate and is then sent to the next station by the first motor driven by the conveyor belt. The entire unloading process is fully automated and requires no manual intervention, which avoids safety risks and significantly improves production efficiency. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0025] Please refer to Figures 1-5 An automatic unloading device for stamping in the production and processing of automotive parts according to this embodiment includes a base 1. Support legs 2 are fixedly connected to the four corners of the top of the base 1. A top seat 3 is fixedly installed on the top of the support legs 2. A frame 4 is fixedly installed on the top of the top seat 3. A hydraulic cylinder 5 is fixedly installed on the top of the frame 4. An upper mold 6 is fixedly installed through the frame 4 at the output end of the hydraulic cylinder 5. A lower mold 7 is fixedly installed in the middle of the top seat 3. An unloading mechanism 8 is fixedly installed on one side of the frame 4. A demolding mechanism 9 is fixedly installed on the back of the upper mold 6. The top of the demolding mechanism 9 passes through the top seat 3 and is disposed inside the lower mold 7.

[0026] The demolding mechanism 9 includes a connecting rod 91, which is fixedly installed on the rear side of the upper mold 6. A base frame 92 is fixedly connected to the bottom of the connecting rod 91. Demolding ejector rods 93 are fixedly installed at the four corners of the top of the base frame 92. The ends of the demolding ejector rods 93 pass through the top seat 3 and the upper mold 6. Demolding templates 94 are fixedly connected to the top seat 3 and the upper mold 6. The demolding templates 94 are movable inside the lower mold 7. During the application of this device, when the automatic unloading device for stamping is working, the base 1 provides stable support through the support legs 2 at the four corners and the top seat 3. The hydraulic cylinder 5 at the top of the frame 4 serves as the power core, driving the upper mold 6 to perform vertical stamping. When the hydraulic cylinder 5 drives the upper mold 6 to rise, the demolding mechanism 9 fixed to the rear side of the upper mold 6 operates synchronously: the connecting rod 91 acts as a transmission hub, transmitting the lifting force of the upper mold 6 to the base frame 92, causing the base frame 92 to move upward; the demolding ejector rods 93 at the four corners of the top of the base frame 92 then pass through the top seat 3 and the upper mold 6, pushing the demolding plate 94 to move upward inside the lower mold 7, ejecting the stamped automotive parts from the lower mold 7, completing the automatic demolding. This process cleverly utilizes the lifting stroke of the upper mold 6, integrating the demolding action with the stamping process, eliminating the need for an additional independent demolding device, simplifying the equipment structure, reducing costs, and achieving efficient and automated demolding.

[0027] Please refer to Figures 1-4The feeding mechanism 8 includes a side rail 81, which is fixedly installed on the upper side of one side of the frame 4. A second motor 82 is fixedly installed at the rear end of the frame 4. A lead screw 83 is fixedly installed through the side rail 81 at the output end of the second motor 82. The lead screw 83 is rotatably connected to the inside of the frame 4. A slider 84 is threadedly connected to the outer surface of the lead screw 83. A push frame 85 is fixedly installed on one side of the slider 84. The push frame 85 includes a connecting rod 851, which is fixedly connected to the inner side of the slider 84. A connecting frame 852 is fixedly installed at the front end of the slider 84. A push plate 853 is fixedly installed at the bottom of the connecting frame 852. The push plate 853 is located at the rear side of the lower mold 7. During the use of this device, after the second motor 82 at the rear end of the frame 4 is started, the output shaft drives the lead screw 83 to rotate. Due to the connection between the lead screw 83 and the slider 85, the feed mechanism 85 rotates. Block 84 is connected by a thread, and the rotational motion of the lead screw 83 is converted into the linear motion of the slider 84 along the side rail 81. The side rail 81 is fixed to the upper side of the frame 4, and its internal structure provides a guide rail for the slider 84 to ensure that the slider 84 moves smoothly. When the slider 84 moves, it drives the push frame 85 connected to the inner connecting rod 851 to move forward synchronously. The connecting frame 852 at the front end of the push frame 85 and the bottom push plate 853 move accordingly. The push plate 853 located on the rear side of the lower mold 7 pushes the demolded automotive parts out of the surface of the lower mold 7. This process is driven by the motor to drive the lead screw 83 to achieve precise linear motion of the push frame 85. The material unloading action is completed by mechanical linkage without manual intervention, which significantly improves the efficiency of stamping parts discharge. Moreover, the structure is compact and the transmission is stable, which can adapt to the continuous operation requirements of automated production lines.

[0028] Please refer to Figures 1-3A conveyor frame 11 is fixedly installed at the center of the top front end of the base 1. A conveyor belt 12 is rotatably connected inside the conveyor frame 11. A first motor 13 is fixedly connected to one front end of the conveyor frame 11. The output end of the first motor 13 passes through the conveyor frame 11 and is connected to the rotating shaft inside the conveyor belt 12. The internal cavity cross-section of the side rail 81 is set in a convex shape. The side shape of the slider 84 is also set in a convex shape. Wear-resistant pads are fixedly connected to the outer surface of the slider 84. A guide plate 10 is fixedly installed at the center of the front end of the top seat 3. The guide plate 10 is inclined. During the use of this device, the conveyor belt 12 and the guiding structure can cooperate to realize automated material unloading. In specific use, the inclined guide plate 10 at the front end of the top seat 3 receives the automotive parts pushed out after demolding and guides the workpieces to slide down the inclined plane to the conveyor frame 11 at the front end of the base 1 by gravity. The conveyor belt 12 inside 11 is driven by the first motor 13 on one side. The output shaft of the motor drives the internal rotating shaft of the conveyor belt 12 to rotate, so that the conveyor belt 12 runs continuously and transports the slipped workpiece to the next station. The side rail 81 adopts a convex cross-section design, which forms a nested fit with the slider 84, which is also convex, to ensure that the slider 84 slides smoothly under the drive of the lead screw 83 without leaving the track. The wear-resistant pad on the outer surface of the slider 84 further reduces friction loss and extends the service life of the mechanism. In the whole process, the tilt angle of the guide plate 10 matches the transmission speed of the conveyor belt 12, realizing the seamless connection of the workpiece from demolding to conveying, and ensuring the continuous and efficient operation of the production line. This technology uses a displacement sensor in conjunction with a PLC control system to assist in intelligent identification and control. The intelligent control system of this technical solution is a conventional technical means of existing control systems, so it will not be described in detail here.

[0029] Operating principle and advantages: During the stamping operation, the hydraulic cylinder 5 on the top frame 4 is the core power source, driving the upper mold 6 to reciprocate vertically. Unlike traditional stamping equipment, this device integrates the demolding function into the movement of the upper mold 6. When the hydraulic cylinder 5 retracts and drives the upper mold 6 to rise, the demolding mechanism 9 fixed on the back of the upper mold 6 moves upward synchronously. The connecting rod 91 acts as a force transmission component, driving the base frame 92 to rise, which in turn causes the demolding ejector rods 93 at the four corners of the top of the base frame 92 to move upward synchronously. The demolding ejector rods 93 pass through the top seat 3 and the upper mold 6, pushing the demolding plate 94 to push the stamped product in the lower mold 7 upward. This design cleverly utilizes the lifting and lowering movement of the upper mold 6 to combine the demolding action with the stamping process. There is no need to configure an additional independent demolding drive system, which saves equipment costs and simplifies the mechanical structure.

[0030] After demolding, the unloading mechanism 8 starts quickly. The second motor 82 inside the frame 4 serves as the power unit, and its output shaft drives the lead screw 83 to rotate. Since the lead screw 83 and the slider 84 are driven by a threaded transmission, the rotation of the lead screw 83 is converted into the linear motion of the slider 84 along the side rail 81. The side rail 81 adopts a convex cross-section design, which cooperates with the slider 84, which is also convex, to ensure that the slider 84 will not leave the track during movement. At the same time, the wear-resistant pads on the outer surface of the slider 84 can reduce friction and extend service life. When the slider 84 moves forward, it drives the push frame 85. Synchronously moving forward, the push plate 853 at the front end of the push frame 85 pushes the demolded product out from the rear side of the lower mold 7. The pushed product slides down along the inclined guide plate 10 and enters the conveyor belt 12 in the conveyor frame 11. The first motor 13 on one side of the conveyor frame 11 drives the conveyor belt 12 to operate, quickly transporting the product to the next station, realizing the full automation of the unloading process. The whole process does not require manual intervention, which not only avoids the safety hazards caused by manual operation, but also greatly improves production efficiency and effectively solves the problems of high demolding cost and low efficiency of traditional stamping devices.
