Description

Technical Field

[0001] The utility model belongs to the technical field of engine cylinder head casting equipment, and in particular relates to a TNGA core making machine core head tray turning device. Background Art

[0002] TNGA (Toyota New Global Architecture) is a new automotive production architecture designed to improve product quality, reduce costs, and accelerate time to market by integrating R&D, design, and production. In the core-making machine production process, the application of TNGA is reflected in improving production efficiency and optimizing production processes. However, traditional methods have significant efficiency and safety issues in core-making machine unloading and subsequent core head processing.

[0003] Specifically, after the core making machine completes the sand core production, the unloading arm will receive the sand core and return it, leaving the core head (i.e., a specific part of the sand core) on the pallet. The operator needs to remove the core heads from the pallet one by one and then put them into the residual sand recovery vehicle. This process is not only time-consuming and labor-intensive, but also prone to causing a series of problems. The operator needs to manually remove the core head from the pallet and put it into the recovery vehicle each time. This repetitive work not only increases the working time, but also reduces the overall production efficiency. Especially in a high-volume, fast-paced production environment, this inefficient working method is obviously unable to meet production needs. Moreover, due to the small working space when the core head is put into the recovery vehicle, the operator's arm is prone to contact with components such as the sand core support rod, posing safety hazards such as scratches. In addition, the core making machine shutdown problem caused by grating obstruction also increases the operating risk, requiring the operator to frequently manually restore the abnormality, further exacerbating the safety hazard. Therefore, the utility model provides a TNGA core making machine core head pallet flipping device, which is used to flip the pallet so that the sand core core head falls naturally due to gravity, thereby realizing semi-automatic core head recovery instead of manually picking up the core head. Utility Model Content

[0004] In order to overcome the problems existing in the related art, the utility model provides a TNGA core making machine core head tray turning device.

[0005] The technical solution of the utility model is as follows:

[0006] A TNGA core making machine core head tray turning device is provided with:

[0007] Tray body;

[0008] The rear end of the tray body is connected to the outer side of the discharge arm through a hinge, and a cylinder is installed on the outer side of the discharge arm. The outer end of the output shaft of the cylinder is movably connected to the lower side of the tray body. The upper surface of the tray body is an inclined surface with the front end lower than the rear end. The cylinder is connected to a control box through a connecting line. A flip button is embedded on the outer side of the control box. The control box is installed on the outer side of the TNGA core making machine frame.

[0009] A storage box is placed on the lower side of the tray body, and a distance detection sensor is installed on the upper end of the side of the storage box. The distance detection sensor is connected to the control box through a connecting line.

[0010] In one embodiment, a proximity switch is provided at the lower side of the front end of the tray body, and the proximity switch is installed on the outside of the TNGA core making machine frame. The proximity switch is connected to the control box through a connecting line.

[0011] In one embodiment, an emergency stop switch is embedded on the outside of the control box, and a red warning light is embedded in the middle of the emergency stop switch.

[0012] In one embodiment, the control box is connected to an alarm via a connecting line, and the alarm is installed on the outside of the TNGA core making machine frame.

[0013] In one embodiment, protective edges are integrally provided at the edges of both ends of the tray body.

[0014] In one embodiment, an inclined support plate is fixed on the outside of the discharge arm, and the cylinder is installed on the outside of the inclined support plate.

[0015] Combined with the above technical solutions, the beneficial effects of the present invention are as follows: the present invention can realize the automatic flipping of the tray through the cooperation of the cylinder and the hinge, so that the core heads of the sand cores can naturally fall into the storage box below due to gravity, replacing the traditional tedious process of manually picking up the core heads one by one, significantly reducing the labor intensity and working time of the operators, and improving the overall production efficiency. The effect is more significant, especially in a high-volume, fast-paced production environment. Since the operator's direct contact with the sand core and its supporting components is reduced, the risk of safety accidents such as scratches is reduced. At the same time, the problem of frequent shutdown of the core making machine due to grating obstruction is avoided, and the situation where the operator needs to manually restore the abnormality is reduced, further reducing the safety hazards during the operation process.

[0016] This utility model reduces human interference and the risk of core damage or contamination due to improper operation, helping to improve the quality stability and consistency of the final product. The flip button and distance detection sensor on the control box make pallet flipping easier and more convenient. It also facilitates real-time monitoring of the storage box's status, prompting operators to clean or replace it, ensuring the continuity and stability of the production process. Furthermore, the device's relatively simple structure makes it easy to install and maintain, reducing equipment costs.

[0017] This new design makes the core head recovery process smoother and more efficient, aligning with the overall concept of the TNGA architecture, which aims to improve product quality and production efficiency by integrating and optimizing each link. The introduction of the tray flipping device is a significant optimization of the core making machine production process, helping to enhance the automation and intelligence level of the entire production line.

[0018] To sum up, the utility model has demonstrated significant technical effects in improving production efficiency, reducing safety risks, optimizing production processes, facilitating management and maintenance, and improving product quality. It is a successful application of the TNGA architecture in the core-making machine production process. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the following detailed description of specific embodiments of the present invention is provided in conjunction with the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without violating the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] like Figure 1 As shown, the rear end of the tray body 1 in the TNGA core-making machine core head tray flipping device provided by the embodiment of the utility model is connected to the outer side of the unloading arm 3 through a hinge 2, and a cylinder 4 is installed on the outer side of the unloading arm 3, and the outer end of the output shaft of the cylinder 4 is movably connected to the lower side of the tray body 1, and the upper surface of the tray body 1 is an inclined surface with the front end lower than the rear end, and the cylinder 4 is connected to the control box 5 through a connecting line, and a flip button 6 is embedded on the outer side of the control box 5, and the control box 5 is installed on the outer side of the TNGA core-making machine frame 7; a storage box 8 is placed on the lower side of the tray body 1, and a distance detection sensor 9 is installed on the upper end of the side of the storage box 8, and the distance detection sensor 9 is connected to the control box 5 through a connecting line.

[0025] Preferably, a proximity switch 10 is provided on the lower front end of the tray body 1 in the embodiment of the present invention. The proximity switch 10 is mounted on the outside of the TNGA core making machine frame 7 and is connected to the control box 5 via a connecting line. The proximity switch 10 enables automated monitoring and control. When the tray body 1 moves within the sensing range of the proximity switch 10, the proximity switch 10 sends a signal to the control box 5, triggering appropriate control logic, such as stopping the tray's movement. This helps improve production efficiency, reduce manual intervention, and enhance operational safety.

[0026] Preferably, an emergency stop switch 11 is embedded on the outside of the control box 5 in this embodiment of the utility model, and a red warning light is embedded in the center of the emergency stop switch 11. When an equipment abnormality occurs or the operator needs to stop the equipment immediately, simply press the emergency stop switch 11 to quickly stop the equipment. The red warning light serves as a prominent warning, alerting nearby personnel to the equipment status and preventing accidental contact, thereby enhancing the safety and emergency response capabilities of the equipment.

[0027] Preferably, the control box 5 in the embodiment of the present invention is connected via a connecting line to an alarm 12, mounted on the exterior of the TNGA core making machine frame 7. Alarm 12 can sound an alarm when the distance detection sensor 9 detects that the storage bin 8 is fully loaded. Alarm 12 can also emit audible and visual alarm signals to alert operators when equipment malfunctions, anomalies, or preset alarm conditions are met. This helps promptly identify and address equipment issues, prevent further malfunctions, and ensure smooth production.

[0028] Preferably, an inclined support plate 14 is fixed to the outside of the discharge arm 3 in the embodiment of the present invention, and the cylinder 4 is mounted outside of the inclined support plate 14. The inclined support plate 14 provides a more stable installation of the cylinder 4 and better adapts to angular changes during the flipping process. The inclined support plate 14 also provides a certain degree of cushioning, reducing vibration and impact of the cylinder during the flipping process, thereby extending the service life of the cylinder 4 and improving the stability and reliability of the flipping process.

[0029] like Figure 2 As shown, the pallet body 1 in this embodiment of the present invention is integrally provided with protective edges 13 at both ends. These protective edges 13 provide protection, preventing materials from sliding off the edges or spilling during the flipping process, thereby ensuring the safety and integrity of the materials. Furthermore, these edges can also reduce collision and friction between the pallet and surrounding equipment, lowering the risk of equipment damage.

[0030] The operating principle of the present invention is as follows: During use, a storage box 8 is placed under the tray body 1, ready to receive material that falls after the tray is flipped. After the unloading arm 3 receives the sand core and returns, it retains the core head on the tray. The operator then presses the flip button 6 on the outside of the control box 5 to initiate the flipping process. Following the command from the control box 5, the pneumatic cylinder 4 begins operating, with the outer end of its output shaft pushing the underside of the tray body 1, causing the tray body 1 to rotate about the hinge 2. Driven by the pneumatic cylinder 4, the tray body 1 gradually flips, and the material slides off the tilted tray surface into the storage box 8 below. Simultaneously, a distance detection sensor 9 begins monitoring the loading status of the storage box 8, preparing for a full-load warning. A proximity switch 10 monitors the position of the tray body 1 in real time. When the tray body 1 approaches the proximity switch 10, the pneumatic cylinder 4 stops operating, and the flipping process ends. When the distance detection sensor 9 detects that the storage box 8 is full, an alarm 12 sounds, notifying the operator to replace or empty the storage box 8 promptly. The operator can press the emergency stop switch 11 to stop the equipment urgently as needed.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some or all of the technical features therein, and these modifications or replacements should all be included in the scope of protection of the present invention.
