[0002] At present, the molding technology of metal castings is developing rapidly. Sand casting is a widely used casting form. Steel, iron and most alloy castings can be obtained by sand casting. Since the molding materials used in sand casting are cheap and easy to obtain, the casting mold is simple to manufacture, and it can adapt to the single-piece production, batch production and mass production of castings, it has long been the basic process in casting production. In modern production, the automated production line replaces the original manual production, which greatly improves the production efficiency. After the sand mold making equipment makes the sand mold, a cart is usually used to transport the sand mold to the casting area. In the casting area, liquid metal needs to be injected into the cavity of the sand mold, and then the sand mold is transported out of the casting area by a cart. After the sand mold is transported out of the casting area, the sand mold and the cart need to be separated to take out the metal in the sand mold. At the same time, the cart can be recycled. In the prior art, the sand mold is usually transported from the sand mold molding machine to the cart by manual means, which is inefficient and inconvenient to operate. Utility Model Content

DETAILED DESCRIPTION

[0019] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0020] Combination Figure 1 , Figure 2 and Figure 3As shown, a mold removal device of a vertical sand mold forming machine is used to remove the manufactured sand mold from the sand mold forming machine 1, including a material track 2 arranged below the discharge port 1a of the sand mold forming machine 1, a material car 3 for loading the sand mold on the material track 2, and a mold removal mechanism 4 installed on the material track 2, and the mold removal mechanism 4 includes a lifting track 5, a lifting component 6 and a fixing component 7; the lifting track 5 is used to park the material car 3 loaded or to be loaded with the sand mold; the lifting component 6 is used to lift the material car 3 parked on the lifting track 5 to be loaded with the sand mold to the discharge port 1a of the sand mold forming machine 1; the fixing component 7 is used to fix the material car 3 loaded or to be loaded with the sand mold during the lifting process. Specifically, the mold removal device of the vertical sand mold forming machine is designed to be quite ingenious and practical. The sand mold forming machine 1 is the core equipment of the entire mold removal device, which is used to manufacture sand molds. When the sand mold is manufactured, it will be placed at the discharge port 1a, waiting to be taken out. The material track 2 is a track for the movement of the material cart 3, on which the material cart 3 can move freely, so as to facilitate the transportation of the sand mold from the molding machine to other locations. The material cart 3 is a transportation tool for loading the sand mold. After the sand mold is manufactured in the molding machine, the material cart 3 will move to the bottom of the discharge port 1a of the molding machine, ready to receive the sand mold. The mold removal mechanism 4 is a key part of the entire mold removal device, which includes three components to complete the mold removal work together. The lifting track 5 is a temporary parking point for the material cart 3. When the material cart 3 needs to be lifted to the discharge port 1a of the molding machine, it will first be parked on the lifting track 5. The lifting component 6 is responsible for lifting the material cart 3 parked on the lifting track 5 to the discharge port 1a of the molding machine. The lifting component 6 may include some mechanical devices, such as elevators, chains or hydraulic cylinders, etc., for realizing the lifting action. During the lifting process, in order to ensure the stability and safety of the material cart 3, a fixing component 7 is required. This component may include some locking devices or clamps to fix the material cart 3 on the lifting track 5 or the lifting component 6 to prevent it from shaking or falling off during the lifting process. The entire mold removal process is roughly as follows: first, the material cart 3 moves to the lifting track 5 and parks; then, the lifting component 6 is started to lift the material cart 3 to the discharge port 1a of the molding machine; during this process, the fixing component 7 will ensure the stability of the material cart 3; when the material cart 3 reaches below the discharge port 1a, the sand mold in the molding machine will fall onto the material cart 3; finally, the material cart 3 moves on the material track 2 to transport the sand mold to the next process or storage location. This design not only improves the efficiency and safety of mold removal, but also reduces the labor intensity of operators, which is of great significance for improving the automation level of the entire sand mold manufacturing process.

[0021] Combination Figure 2 , Figure 4 and Figure 5As shown, the lifting assembly 6 includes a mounting frame 6a installed on the material track 2, a mounting platform 6b is provided on the top of the mounting frame 6a, a cylinder 6c is fixedly installed on the mounting platform 6b, and a lifting platform 6d is fixedly connected to the output end of the cylinder 6c. Specifically, in the mold removal device of the vertical sand mold forming machine, the lifting assembly 6 is a core part, which is responsible for lifting the material car 3 from the material track 2 to the discharge port 1a of the sand mold forming machine 1. The mounting frame 6a is the basic structure of the lifting assembly 6 and is installed on the material track 2. The mounting frame 6a provides a stable support for the entire lifting assembly 6 to ensure that no shaking or tilting occurs during the lifting process. The mounting platform 6b is located on the top of the mounting frame 6a and is used to carry and fix other components of the lifting assembly 6. It provides a flat and stable working surface to ensure that other components can be correctly installed and work stably. The cylinder 6c is the power source of the lifting assembly 6 and is fixedly installed on the mounting platform 6b. The cylinder 6c is driven by air pressure, and its output end can be retracted, thereby driving the lifting platform 6d to move up and down. The cylinder 6c has the advantages of fast response speed and high control accuracy, and is very suitable for such occasions where precise control of the lifting height is required. The lifting platform 6d is fixedly connected to the output end of the cylinder 6c and is the component that actually carries the material cart 3 for lifting. When the cylinder 6c is working, the lifting platform 6d will move up and down accordingly, thereby driving the material cart 3 parked thereon to lift and lower. The design of the lifting platform 6d should take into account factors such as load-bearing capacity, stability, and matching accuracy with the material cart 3. The entire lifting process is as follows: When the material cart 3 needs to be lifted, the cylinder 6c starts working, and its output end extends to push the lifting platform 6d up. The lifting platform 6d drives the material cart 3 parked thereon to rise together until it reaches the height of the discharge port 1a of the sand mold forming machine 1. In this process, the mounting frame 6a and the mounting platform 6b provide stable support and platform for the entire lifting process. When the material cart 3 reaches the specified position, the cylinder 6c stops working, and the lifting platform 6d and the material cart 3 remain stationary, waiting for the next step of operation. This design makes the lifting assembly 6 simple in structure, easy to operate, stable in lifting and accurate in control, and can meet the requirements of the vertical sand mold molding machine mold removal device for lifting action. At the same time, the use of the cylinder 6c also improves the automation level of the entire mold removal device and reduces the labor intensity of the operator.

[0022] Combination Figure 2 , Figure 3 and Figure 4As shown, when the lifting assembly 6 lifts the material cart 3 upward, the top of the material cart 3 is flush with the bottom of the discharge port 1a. Specifically, when the lifting assembly 6 lifts the material cart 3 upward until the top of the material cart 3 is flush with the bottom of the discharge port 1a, the entire mold removal device reaches a critical working state. This design ensures that the sand mold can smoothly fall into the material cart 3 from the discharge port 1a of the molding machine without falling deviation or failure to fall completely. The top of the material cart 3 is flush with the bottom of the discharge port 1a, which means that the two are precisely docked in the vertical direction. This ensures that the sand mold can fall directly and accurately into the material cart 3 when it is pushed out of the molding machine, reducing the risk of damage to the sand mold during the transfer process. Due to the precise docking, the transportation process of the sand mold becomes more efficient. Once the sand mold is pushed out of the molding machine and falls into the material cart 3, the material cart 3 can be immediately moved to the next process or storage location without additional adjustment or correction. This design reduces the difficulty and workload of the operator. The operator does not need to accurately control the position or height of the material cart 3, but only needs to ensure that the material cart 3 is parked in the correct position on the lifting track 5, and then the lifting component 6 automatically completes the lifting and docking action. Accurate docking reduces the shaking or falling off of the sand mold during transportation, thereby improving the safety of the entire mold removal process. In order to achieve this precise docking, the design and control of the lifting component 6 are very important. For example, the telescopic stroke of the cylinder 6c needs to be accurately controlled to ensure that the lifting platform 6d can be accurately lifted to the specified position. At the same time, the stability of the mounting frame 6a and the mounting platform 6b is also crucial. They need to be able to withstand various forces and moments during the lifting process to maintain the stability and accuracy of the entire lifting component 6. In general, when the lifting component 6 lifts the material cart 3 upward so that its top is flush with the bottom of the discharge port 1a, the mold removal device reaches an efficient, accurate and safe working state, providing strong support for the entire sand mold manufacturing process.

[0023] Combination Figure 2 , Figure 4 and Figure 5As shown, the fixing assembly 7 includes a rotating motor 7a installed on the lifting platform 6d, and the output end of the rotating motor 7a is fixedly connected to a rotating clamp 7b. Specifically, the fixing assembly 7 plays a key role in the mold removal device. It ensures that the material cart 3 remains stable during the lifting process to prevent accidents caused by shaking or tilting. The rotating motor 7a is installed on the lifting platform 6d, which ensures that the motor can be lifted and lowered together with the lifting platform 6d, thereby fixing the material cart 3. The main function of the rotating motor 7a is to provide rotational power, and its output end is fixedly connected to the rotating clamp 7b. When the material cart 3 needs to be fixed, the rotating motor 7a is started to drive the rotating clamp 7b to rotate. The rotating clamp 7b is fixedly connected to the output end of the rotating motor 7a, so it can rotate with the rotation of the motor. The design of the rotating clamp 7b allows it to clamp or release the material cart 3 through a rotating action. When the clamp rotates to a suitable position, it can tightly clamp a part of the material cart 3 (such as the edge of the car body or a specific clamp), thereby fixing it on the lifting platform 6d. When the material cart 3 needs to be released, the clamping block rotates in the opposite direction to release the clamping of the material cart 3. The working process of the fixing component 7 is as follows: before lifting the material cart 3, the lifting platform 6d will drop to an appropriate position so that the rotating clamping block 7b can approach the material cart 3. The rotating motor 7a is started to drive the rotating clamping block 7b to rotate to the clamping position to fix the material cart 3 on the lifting platform 6d. The lifting component 6 starts to work, and the lifting platform 6d rises with the fixed material cart 3. When the material cart 3 reaches the specified position (such as flush with the discharge port 1a), the rotating motor 7a is started again to drive the rotating clamping block 7b to rotate to the release position to release the clamping of the material cart 3. The material cart 3 can now move freely on the material track 2 for subsequent transportation or storage operations. Through this design, the fixing component 7 can ensure the stability and safety of the material cart 3 during the lifting process, and prevent damage to the sand mold or operation accidents caused by shaking or tilting. At the same time, the flexibility and reliability of the rotating clamping block 7b also improve the automation level and operation efficiency of the entire mold removal device.

[0024] Combination Figure 2 , Figure 4 and Figure 5As shown, the fixed assembly 7 includes at least two rotating motors 7a, and the output ends of all rotating motors 7a are fixedly connected with rotating clamps 7b. Specifically, the design of the fixed assembly 7 has been further optimized and enhanced. By introducing at least two rotating motors 7a and fixing rotating clamps 7b at the output ends of each rotating motor 7a, this method significantly improves the stability and safety of the material cart 3 during the lifting process. When multiple rotating motors 7a and corresponding rotating clamps 7b work together, they can clamp the material cart 3 from multiple angles and positions. This multi-point fixing method can more effectively prevent the material cart 3 from shaking or tilting during the lifting process, thereby ensuring the stability of the entire mold-taking process. Multi-point fixing not only enhances stability, but also improves safety. Even if one of the rotating clamps 7b fails to work properly for some reason, the other clamps can still continue to clamp the material 3 car to prevent it from falling off or accidents. By adjusting the positions and angles of different rotating motors 7a and rotating clamps 7b, the fixed assembly 7 can adapt to material carts 3 of different sizes and shapes. This flexibility enables the mold removal device to handle more types of material carts 3, improving the versatility and use efficiency of the equipment. Since multiple rotating motors 7a and rotating clamps 7b can work at the same time, the operations of fixing and releasing the material cart 3 can be completed faster. This helps to improve the operational efficiency of the entire mold removal process and reduce the production cycle time. In practical applications, the specific design of the fixed component 7 may need to be adjusted according to the size, weight and overall layout of the mold removal device of the material cart 3. For example, the number, position and clamping force of the rotating motors 7a and the rotating clamps 7b need to be accurately calculated and reasonably configured according to the specific circumstances to ensure that they can effectively fix the material cart 3 and meet production needs. In short, by adopting the design of multiple rotating motors 7a and rotating clamps 7b, the fixed component 7 has been significantly improved in stability and safety, while enhancing its adaptability and operational efficiency, providing a more reliable and efficient fixing solution for the mold removal device of the vertical sand mold forming machine.

[0025] Combination Figure 2 , Figure 4 and Figure 5As shown, the rotating clamp block 7b includes a rotating shaft 7b1 fixedly mounted on the output end of the rotating motor 7a, and a fixed block 7b2 is fixedly connected to the bottom of the rotating shaft 7b1. Specifically, the rotating clamp block 7b is a key part of the fixing assembly 7, and its design directly determines the fixing effect and stability of the material cart 3. According to the description, the rotating clamp block 7b is composed of a rotating shaft 7b1 and a fixed block 7b2, and the rotating shaft 7b1 is fixedly mounted on the output end of the rotating motor 7a, which means that when the rotating motor 7a is started, the rotating shaft 7b1 will rotate accordingly. This direct connection ensures the efficient power transmission of the rotating motor 7a, so that the rotating clamp block 7b can respond to control instructions quickly and accurately. The rotation function of the rotating shaft 7b1 is the key to achieving the fixation of the material cart 3. By rotating, the clamp block can adjust its position so as to clamp or release the material cart 3. This flexibility enables the fixing assembly to adapt to material carts 3 of different sizes and shapes, thereby improving its versatility. The fixed block 7b2 is fixedly connected to the bottom of the rotating shaft 7b1, which means that the fixed block 7b2 will move with the rotation of the rotating shaft 7b1. This connection method ensures the stability and reliability of the fixed block 7b2 when clamping the material cart 3. The main function of the fixed block 7b2 is to clamp the material cart 3 directly. Its design may include a clamping surface, a clamping force adjustment mechanism, etc. to ensure that the material cart 3 can be firmly fixed to prevent shaking or falling off during the lifting process. In order to ensure the durability and reliability of the fixed block 7b2, a material with sufficient hardness and wear resistance is usually selected for manufacturing. In addition, considering that it may be necessary to frequently contact the material cart 3, the selection of materials should also take into account its friction coefficient and wear resistance. In summary, the rotating clamp 7b achieves effective fixation of the material cart 3 through the coordinated work of the rotating shaft 7b1 and the fixed block 7b2. This design not only ensures the stability of the material cart 3 during the lifting process, but also improves the safety and reliability of the entire mold removal device. At the same time, its flexibility and versatility also enable the fixed component to adapt to different scenarios and needs.

[0026] Combination Figure 2 , Figure 4 and Figure 5As shown, the fixed block 7b2 is fixedly connected to the rotating shaft 7b1 in a vertical state. Specifically, the design that the fixed block 7b2 is fixedly connected to the rotating shaft 7b1 in a vertical state plays a key role in the fixed assembly 7. The fixed block 7b2 is vertically connected to the rotating shaft 7b1. This structure enables the fixed block 7b2 to provide more stable support when clamping the material cart 3. Due to the characteristics of the vertical connection, the fixed block 7b2 can better withstand the weight and force from the material cart 3, reduce the shaking or offset during the lifting process, and thus ensure the stable transportation of the material cart 3. The vertically connected fixed block 7b2 can clamp the material cart 3 more effectively. When the rotating motor 7a drives the rotating shaft 7b1 to rotate, the fixed block can perform a clamping action in a direction perpendicular to the surface of the material cart 3, thereby increasing the clamping force and reducing the possibility of sliding. This design helps to ensure that the material cart 3 is firmly fixed during the lifting process to prevent it from falling off or shifting. The vertically connected fixed block 7b2 can be flexibly adjusted according to the size and shape of the material cart 3. Since the fixed block 7b2 is perpendicular to the rotating shaft 7b1, it can move up and down or adjust the angle along the axial direction of the rotating shaft 7b1 to adapt to the clamping requirements of different material carts 3. This flexibility enables the fixed assembly 7 to be more widely used in material carts 3 of different specifications and types, improving its versatility and practicality. The vertical connection design between the fixed block 7b2 and the rotating shaft 7b1 is relatively simple and clear, easy to manufacture and install. This structure reduces the complex connection and assembly requirements between components, reduces manufacturing costs and maintenance difficulties. At the same time, the simple structure also means higher reliability and durability, and reduces the possibility of failure. In summary, the design of the fixed block 7b2 being fixedly connected to the rotating shaft 7b1 in a vertical state not only enhances the stability and clamping force of the fixed assembly 7, but also improves its adaptability and practicality. This design enables the fixed assembly 7 to better fix the material cart 3, ensuring stability and safety during the lifting process.

[0027] Combination Figure 1 , Figure 2 and Figure 3As shown, the material cart 3 is made of metal. Specifically, the material cart 3 is made of metal, and this choice is based on its multiple superior properties and characteristics. Metal materials have high strength and toughness and can withstand large weight and impact. This enables the metal material cart 3 to withstand various forces that may be generated during transportation, lifting and storage, ensuring stability and reliability for long-term use. The structure of the metal material cart 3 is stable and not easy to deform or damage. During the lifting process, the metal material cart 3 can remain stable, reducing the risk of shaking and tilting, thereby ensuring the safe transportation of the sand mold. In addition, the surface of the metal material is smooth, not easy to produce friction or jamming, which helps to improve the smoothness of the lifting operation. Metal materials usually have good corrosion resistance and can resist erosion in harsh environments such as moisture, acid and alkali. This is particularly important for the material cart 3 used in the factory environment, which can ensure the long-term service life and stable performance of the material cart 3. The surface of the metal material cart 3 is easy to clean and not easy to accumulate dust and dirt. This helps to maintain the cleanliness of the material cart 3 and reduce the quality problems of the sand mold caused by pollution. At the same time, the maintenance of metal materials is relatively simple, and their service life can be extended by painting, rust prevention and other methods. Metal materials can be recycled and reused, which meets environmental protection requirements. After the material cart 3 is scrapped, the metal material can be recycled to reduce resource waste and environmental pollution. In summary, the material cart 3 made of metal materials performs well in strength, stability, safety, corrosion resistance, cleaning and maintenance, and environmental sustainability, and is very suitable for the mold removal device of the vertical sand mold forming machine. However, when selecting metal materials, factors such as cost and processing difficulty also need to be considered to ensure that the comprehensive performance and economy of the material cart 3 are optimally balanced.
