Description

Technical Field

[0001] This utility model relates to the field of quick-change sand-shooting plate technology, and more specifically, to a convenient quick-change sand-shooting plate receiving mechanism. Background Technology

[0002] The quick-change sand-shooting plate picking mechanism enables the rapid and convenient replacement of sand-shooting plates. The original quick-change picking mechanism and equipment were integrated, and the picking mechanism was moved by the extension of the hydraulic cylinders on both sides to replace the sand-shooting plate and perform sand cleaning. Because the picking mechanism and equipment were integrated, the size space between the picking mechanism and the sand-shooting plate was limited, which restricted the movement stroke of the hydraulic cylinder. During use, the stroke was insufficient, and the most ideal angle could not be reached. Furthermore, due to the limited space, if the sand-shooting head on the sand-shooting plate was too long, the sand cylinder could not be moved to the corresponding position, affecting the replacement of the sand-shooting plate.

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Example

[0017] Reference Figures 1-4This utility model provides a technical solution: a convenient quick-change and receiving mechanism for sand-shooting plates, including a support frame 1, with pulleys 2 at the bottom of the support frame 1, and a receiving mechanism 3 installed on the top of the support frame 1. A sand-shooting plate 4 is installed above the receiving mechanism 3. The sand-shooting plate 4 can be replaced through the receiving mechanism 3. The support frame 1 is made of Q235B low carbon steel plate, which is CNC cut and welded to ensure sufficient anti-deformation capacity and load-bearing strength, and can stably support the overall weight of the sand-shooting plate 4 and the receiving mechanism 3. The welded joints of the support frame 1 are treated with full welding process and hot-dip galvanized surface treatment technology to effectively improve the anti-rust ability, adapt to the harsh environment of the foundry workshop with sand, dust and humidity, and extend the overall service life of the mechanism. A rectangular plate is also fixedly installed on the top of the support frame 1. The surface of the rectangular plate is set as a flat plane so as to stably place the support plate 31 in the receiving mechanism 3.

[0018] Pulleys 2 are symmetrically arranged at the bottom of the support frame 1. The wheel body of pulley 2 is made of high-strength nylon material through one-piece injection molding. This material not only has excellent wear resistance, but also effectively reduces noise during movement and avoids scratches caused by hard contact with the ground. The shaft of pulley 2 is made of 304 stainless steel and is equipped with high-precision rolling bearings to ensure flexible and smooth rotation, reduce frictional resistance during movement, and allow the mechanism to be easily pushed on the workshop floor. In addition, pulley 2 is equipped with a self-locking device. The self-locking component is made of wear-resistant cast iron. When locked, the wheel body can be fixed by a mechanical clamping structure to prevent the mechanism from accidentally sliding during sand shooting operations or replacement, ensuring operational safety.

[0019] The sand-shooting plate 4 is made of ZG310-570 cast steel, which has high strength, high toughness and excellent heat resistance. It can withstand the high pressure impact and instantaneous high temperature during sand-shooting operations, and avoid deformation or damage.

[0020] In a preferred embodiment, the receiving mechanism 3 includes a support plate 31 and a hydraulic cylinder 32. The support plate 31 is stably installed on the top of the support frame 1. As a load-bearing component of the sand-shooting plate 4, the support plate 31 is made of 6061-T6 high-strength aluminum alloy sheet by CNC milling. It can stably bear the weight of sand-shooting plates 4 of different specifications and has excellent resistance to deformation, avoiding warping caused by long-term stress. The upper surface of the support plate 31 is treated with hard anodizing, which greatly enhances its wear resistance and effectively resists the friction and wear caused by frequent picking and putting of the sand-shooting plate 4. At the same time, the oxide film has good resistance to oil stains and sand dust corrosion, making it suitable for the harsh environment of the foundry workshop.

[0021] In a preferred embodiment, a pad 5 is provided on the top of the support plate 31. The pad 5 is made of high-strength polyurethane elastomer material and is integrally molded. It can buffer the high-frequency vibration generated during sand shooting operation through elastic deformation, reduce the impact of vibration on the installation accuracy of the sand shooting plate 4, and avoid the problem of uneven sand shooting caused by the deviation of the sand shooting hole. It can also resist the erosion of sand and dust and the friction of the metal contact surface. Its wear resistance is 3-5 times that of ordinary rubber. It can withstand the weight of the sand shooting plate 4 and the impact of operation for a long time without deformation or cracking.

[0022] In a preferred embodiment, a vertical rod 6 is fixedly installed inside the support plate 31, and the vertical rod 6 penetrates through the bottom of the support plate 31. The vertical rod 6 is made of 40Cr alloy structural steel and is forged, which can effectively resist the instantaneous impact force during sand shooting operation and avoid bending or breakage caused by long-term stress. The interior of the vertical rod 6 is hollow, and a positioning plate 7 is fixedly installed inside the vertical rod 6. A hydraulic cylinder 32 is fixedly installed on the upper surface of the positioning plate 7.

[0023] The vertical rod 6 adopts a hollow structure design. This design effectively reduces the overall weight of the vertical rod 6 and the load on the mechanism without compromising structural strength. It also provides a closed and stable internal space for the installation of the hydraulic cylinder 32, preventing sand, dust and oil from the foundry workshop from directly corroding the core components of the hydraulic cylinder and extending its service life. The hydraulic cylinder 32 is model HOB80×100-CB. This model is a standard heavy-duty tie rod hydraulic cylinder, which is suitable for heavy-duty and high-frequency operation scenarios of industrial equipment. The specific parameters and installation compatibility are as follows: cylinder diameter 80mm, piston rod stroke 100mm, rated working pressure 16MPa, and maximum thrust up to 80kN. It fully meets the load-bearing requirements of the sand-shooting plate 4 when it is raised and lowered, and can smoothly push the sand-shooting plates 4 of different specifications to rise and fall quickly.

[0024] An internal support column 8 is fixedly installed on the sand-shooting plate 4, and the position of the support column 8 corresponds to the position of the telescopic end of the hydraulic cylinder 32. It is used to push the sand-shooting plate 4 to move. The support column 8 is made of ZG310-570 cast steel and can stably withstand the rated thrust of 80kN output by the hydraulic cylinder 32, avoiding deformation or breakage under stress.

[0025] A rectangular hole 9 is opened on the outer side of the vertical rod 6 at a position corresponding to the oil receiving end of the hydraulic cylinder 32. The rectangular hole 9 penetrates the interior of the vertical rod 6. The rectangular hole 9 is set so that the connecting oil pipe on the hydraulic cylinder 32 extends out from the interior of the vertical rod 6, which facilitates connection with external oil supply equipment to ensure the normal use of the hydraulic cylinder 32.

[0026] A positioning post 10 is installed at the outer end of the support plate 31. The positioning post 10 is circular in shape. The precise fit between the positioning post 10 and the positioning hole of the sand-shooting plate 4 can control the horizontal offset of the sand-shooting plate 4 within ±0.02mm, ensuring that the sand-shooting hole on the sand-shooting plate 4 is completely aligned with the cavity hole of the core-making mold. This is the key to avoiding uneven sand shooting and defects in sand core forming, and directly determines the process accuracy of sand casting.

[0027] Specifically, the working process or working principle of the convenient quick-change sand-shooting plate mechanism is as follows: the sand-shooting plate 4 and the support plate 31 are set as separate parts, which facilitates the replacement of the sand-shooting plate 4 and the cleaning of sand, and meets the requirements of use.

[0028] This equipment installs the sand-shooting plate 4 on one side of the sand-shooting head on the core-making machine. In the sand casting process, in order to adapt to the cavity structure of different castings, the sand-shooting plate 4 needs to be replaced frequently. Therefore, when the sand-shooting plate 4 needs to be replaced, the sand-shooting plate 4 can be pushed upward by the telescopic end of the hydraulic cylinder 32 and moved away from the position of the support plate 31, leaving space for easy replacement of the sand-shooting plate 4.

[0029] The replaced sand-shooting plate 4 is placed back on the telescopic end of the hydraulic cylinder 32, and the telescopic end of the hydraulic cylinder 32 is controlled to retract, so that the sand-shooting plate 4 moves back onto the support plate 31 and can be used normally.

[0030] This equipment adopts a split design, which can better free up space to use a more suitable hydraulic cylinder 32, and will not have insufficient thrust. The split design will bring convenience to the equipment maintenance and repair, which can greatly reduce the downtime of the equipment due to maintenance. It is more convenient in the process of transportation and installation, and also has higher reliability and redundancy design. Moreover, the split design improves the versatility of the receiving mechanism 3.
