Description

Technical Field

[0001] This utility model relates to the field of mold manufacturing technology, and in particular to a vibration compaction tooling for external mold shaping. Background Technology

[0002] Molds are widely used in industrial production, especially in casting and injection molding. The design and manufacture of mold structures directly affect product quality and production efficiency.

[0003] A typical mold forming structure consists of an outer mold and an inner mold. During the outer mold forming process, to ensure the compaction of the sand particles in the sand box and improve the quality of the casting, a mold forming vibration compaction device is usually used to assist in the processing. This device typically includes a base, a bracket, and a vibration motor. The vibration motor is mounted on the bracket, and the bracket is mounted on the base. The base and bracket are elastically connected. The vibration motor drives the bracket and the sand box to vibrate, thereby compacting the sand particles. However, some drawbacks often exist in actual operation. For example, direct vibration compaction by the vibration motor may result in uneven compaction, potentially leading to unstable casting quality. Furthermore, manual labor or a crane is required to transport the sand box and mold, making it difficult to ensure the continuity and stability of the operation, resulting in low efficiency. The vibration compaction process also causes significant damage to the sand box, mold, and vibration compaction device, making them prone to failure and resulting in a short service life.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background technology of this utility model, and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0028] like Figures 1 to 5 The external mold shaping and vibration testing fixture shown includes:

[0029] The base frame 10 and the vibration mechanism 20 and the transmission mechanism 30 are sequentially arranged on the top of the base frame 10;

[0030] The base frame 10 is fixedly installed on the ground. The vibration mechanism 20 is used to vibrate and compact the sand box. The transmission mechanism 30 is used to receive the sand box and transport it to the next work station.

[0031] The vibration mechanism 20 includes several airbags 21, a vibration support 22, and a vibration drive 23. The vibration support 22 is connected to the base frame 10. Several airbags 21 are evenly distributed on the vibration support 22. The vibration drive 23 is fixedly connected to the vibration support 22. The transmission mechanism 30 is located on the top of the airbags 21 and is connected to the vibration support 22 and the base frame 10.

[0032] This invention utilizes the elastic properties of the airbag 21 to transmit vibration energy more evenly during vibration, ensuring that sand particles in all parts of the sand box are effectively compacted. This significantly improves the stability of casting quality. Furthermore, the airbag 21 acts as a buffer and vibration transmission medium, effectively reducing the impact of vibration on the sand box, mold, and the entire device, thus reducing equipment wear, minimizing the possibility of malfunctions, and extending the equipment's service life. In addition, the transmission mechanism 30 automatically transports the sand box to the next workstation after compaction, achieving automated production process flow, greatly reducing manual intervention, improving overall production efficiency, and making the entire outer mold production process smoother and more reliable.

[0033] Specifically, the base frame 10 serves as the basic support structure for the entire tooling. It is fixedly installed on the ground to provide a stable installation platform for the vibration mechanism 20 and the transmission mechanism 30. This ensures that the entire device can maintain good balance and stability during operation, withstand various forces, and avoid problems such as poor vibration compaction or equipment damage caused by the instability of the base frame 10.

[0034] Several airbags 21 are evenly distributed on the vibration support 22, playing a crucial role in buffering and uniformly transmitting vibration. During vibration, the airbags 21 can automatically adjust their deformation according to the shape and pressure of the sand box, so that the vibration energy is more evenly distributed throughout the bottom of the sand box, thereby achieving uniform compaction of the sand particles and improving the quality of the casting. At the same time, the elastic properties of the airbags 21 can also effectively absorb and mitigate some of the vibration impact, protect the sand box and mold, and reduce vibration wear. The vibration support 22 is connected to the base frame 10 and serves as the mounting foundation for the airbags 21 and the vibration drive component 23. It must have sufficient strength and rigidity to withstand the various forces generated during vibration and effectively transmit the power of the vibration drive component 23 to the airbags 21, while ensuring the stability and reliability of its own structure. The vibration drive component 23 is fixedly connected to the vibration support 22, providing a power source for the entire vibration system. By generating periodic vibrations, it drives the airbags 21 and the vibration support 22 to vibrate up and down, thereby causing the sand particles in the sand box to vibrate accordingly, achieving the compaction process of the sand particles. The frequency and amplitude of the sand box vibration can be adjusted by regulating the working parameters of the drive components and the vibration effect of the airbag 21, thereby achieving the compaction effect under different working requirements.

[0035] The transmission mechanism 30 is located on top of the airbag 21 and is connected to the vibration bracket 22 and the base frame 10. It is used to receive the sand box that has been vibrated and transport it smoothly and accurately to the next work station, thereby realizing the automated flow of the production process, reducing manual intervention, improving production efficiency and operational stability, and also helping to connect well with other production equipment or work stations and optimize the entire production process.

[0036] Before using the above-mentioned vibration compaction fixture, ensure that the base frame 10 is firmly fixed and that the vibration mechanism 20 and the transmission mechanism 30 are properly connected. Then, place the sand box to be compacted into the starting position of the transmission mechanism 30 and complete all preparatory work before compaction, such as checking the integrity of the sand box and the filling of the sand particles. When the fixture is started, the vibration drive 23 begins to work, generating vibration and transmitting it to the airbag 21 through the vibration bracket 22. After receiving the vibration, the airbag 21 uses its elastic properties to vibrate up and down, evenly transmitting the vibration energy to the transmission mechanism 30 located at its top. The transmission mechanism 30 remains relatively stable during vibration, while transmitting the vibration to the sand box placed on it, causing the sand particles inside the sand box to vibrate and gradually compact, thereby improving the compactness of the sand particles. After the vibration compaction is completed, the vibration drive 23 stops working, and the transmission mechanism 30 starts under the control of the control system. According to the preset program and path, it smoothly and accurately transports the compacted sand box from the vibration mechanism 20 to the next station. After the transfer is completed, the transmission mechanism 30 receives the next sand box into the tooling and begins a new round of vibration compaction.

[0037] Based on the above embodiments, the vibration support 22 includes a frame 221 and multiple transmission plates 222. The four corners of the frame 221 are fixedly connected to the base frame 10. The frame 221 forms a hollow receiving cavity 221a. The multiple transmission plates 222 are arranged in a crisscross pattern in the receiving cavity 221a, and the two ends of the transmission plates 222 are connected to the airbags 21 at both ends along the sand box conveying direction. The vibration drive component 23 is fixed to the side of the transmission plate 222 away from the transmission mechanism 30. The receiving cavity 221a is used to accommodate the transmission plates 222, the vibration drive component 23 and other components, making the overall structure compact. The frame 221 is used to support the transmission plates 222, the upper transmission mechanism 30 and the sand box, and must have sufficient strength and rigidity to ensure structural stability during vibration. The transmission plates 222 are arranged in a crisscross pattern in the receiving cavity 221a, connecting the airbags 21 and the vibration drive component 23, transmitting vibration power, making the airbags 21 vibrate evenly, realizing sand compaction and enhancing structural stability.

[0038] Based on the above embodiment, the airbags 21 are symmetrically arranged at both ends of the frame 221 along the conveying direction of the transmission mechanism 30; the airbags 21 are symmetrically distributed on both sides of the frame 221, so that the transmission plate 222 can uniformly transmit the power of the vibration drive 23 located in the receiving cavity 221a to the airbags 21, so that the vibration energy is more evenly distributed throughout the bottom of the sand box, thereby achieving uniform compaction of sand particles and improving the quality of castings.

[0039] Based on the above embodiments, three sets of airbags 21 are symmetrically arranged and can be distributed at both ends and the middle of the frame 221 in the width direction. While ensuring a reasonable layout of the airbag installation space, it can effectively ensure that the airbags 21 form a uniform and comprehensive vibration compaction effect on the sand box.

[0040] Based on the above embodiments, the transmission mechanism 30 includes a transmission support 31, a walking drive component 32, a transmission assembly 33, and several guide rollers 34. The transmission support 31 is fixedly connected to the vibration support 22 and the base frame 10. The several guide rollers 34 are arranged at equal intervals along the length of the conveying support. The walking drive component 32 is fixedly mounted on the transmission support 31, and its output end is connected to the ends of the several guide rollers 34 through the transmission assembly 33. The transmission support 31 serves as the main support structure of the transmission mechanism 30, providing a mounting foundation for components such as the walking drive component 32, the transmission assembly 33, and the guide rollers 34, ensuring the overall stability of the transmission mechanism 30. Qualitative and reliable; the walking drive component 32 provides power for the transmission of the sand box, and is connected to the transmission component 33 through the output end to drive the guide rollers 34 to rotate, thereby driving the sand box to move smoothly and accurately along the predetermined path; wherein, the walking speed and stability of the sand box can be adjusted by adjusting the transmission speed and power output of the walking drive component 32, thereby further ensuring the efficiency and quality of the transmission process; the transmission component 33 transmits the power of the walking drive component 32 to each guide roller 34, realizing the distribution and transmission of power, and its efficient operation can ensure the synchronous rotation of the guide rollers 34, ensuring the stability and accuracy of the sand box during the transmission process.

[0041] Based on the above embodiments, the transmission assembly 33 includes a chain 331 and a sprocket 332 disposed on the same side end of each guide roller 34. The chain 331 is wrapped around the sprocket 332. The walking drive component 32 is fixedly disposed on the side of the transmission bracket 31 away from the sprocket 332, and its output end is connected to the end of any guide roller 34. The transmission method of the chain 331 and sprocket 332 can ensure the uniform transmission of power, improve the stability and accuracy of transmission, and at the same time have high transmission efficiency and reliability. In addition, since the transmission assembly 33 is disposed in the external space, it is convenient for inspection and maintenance, and improves the convenience of operation.

[0042] Based on the above embodiments, the transmission mechanism 30 also includes positioning blocks 35. Two positioning blocks 35 are provided and fixedly installed inside the transmission support 31, located between the two guide rollers 34, and opposite to the two ends of the bottom of the sand box along the conveying direction. The positioning blocks 35 limit and correct the position of the sand box during the transmission process, ensuring that the sand box always moves smoothly and accurately along the predetermined path, reducing shaking and deviation during the transmission process, improving the stability and accuracy of the transmission. At the same time, after the sand box reaches the set position, it can send a signal to control the walking drive 32 to stop working, ensuring the accuracy of the position of the sand box when it is subsequently vibrated, and preventing safety accidents caused by instability of the center of gravity and position.

[0043] Based on the above embodiments, the base frame 10 includes a support part 11 and an operating part 12. The support part 11 has protruding corners to form a lifting platform 111. The vibration bracket 22 and the transmission bracket 31 each have auxiliary supports on their sides that correspond one-to-one with the lifting platform 111. The auxiliary supports are fixedly connected to the corresponding lifting platforms 111. The operating part 12 is located on one side of the support part 11, and the top surface of the operating part 12 forms an auxiliary operating table surface, which is higher than the top surface of the support part 11. The support part 11 serves as the basic support structure of the entire tooling. The lifting platforms 111 formed by its protruding corners are fixedly connected to the auxiliary supports of the vibration bracket 22 and the transmission bracket 31, providing a stable installation foundation for the vibration mechanism 20 and the transmission mechanism 30. This ensures that the equipment can maintain good balance and stability during operation, so as to bear the weight of the equipment and the dynamic load during operation, and avoid problems such as poor vibration effect or equipment damage caused by the instability of the base frame 10. The auxiliary operating table surface formed on the top surface of the operating part 12 provides convenient operating space for operators, improving the convenience and efficiency of operation.
