Description

Technical Field

[0001] The utility model relates to the technical field of rapid prototyping of hydraulic components, and more specifically, to a rapid prototyping device for hydraulic components which is convenient for water cooling circulation. Background Art

[0002] A water cooling cycle is a system that uses water as a cooling medium to transfer heat through a circulating flow, thereby achieving efficient heat dissipation. In addition, water cooling cycle systems are widely used in industrial cooling, air conditioning systems, power generation, etc. Their advantages include the ability to effectively control temperature and improve the operating efficiency and reliability of equipment. At the same time, this system also helps to save water resources because it can recycle cooling water and reduce water consumption.

[0003] The hydraulic component rapid prototyping device is a device that uses the principle of liquid transmitting pressure in a closed system to process and shape workpieces by controlling the flow direction, flow rate and pressure of the fluid. The hydraulic component rapid prototyping device integrates the advantages of hydraulic technology and rapid prototyping technology, and can quickly and accurately manufacture the required hydraulic components, which is of great significance for improving production efficiency and product quality.

[0004] A hydraulic component rapid prototyping device that is convenient for water cooling circulation generally refers to a device that integrates an efficient heat dissipation system and advanced manufacturing technology. It realizes the rapid manufacturing of hydraulic components through the principle of water cooling. Before starting the operation, ensure that all equipment is in a safe state. Then the staff needs to accurately place the pre-designed molding mold into the corresponding mold groove according to the design requirements. After the mold is placed, start the hydraulic system to process and mold the workpiece. After the molding is completed, the staff can open the device and take out the molded hydraulic component. This method generally involves the staff holding the molded workpiece into the mold groove, and then the staff takes out the molding mold from the mold groove. Manual operation has the advantages of low cost, strong flexibility, and wide adaptability. However, at the same time, the staff is required to put the workpiece to be formed into the mold groove for a while. When the workpiece is formed, the workpiece needs to be taken out and placed in the storage position again, so that the staff needs to move constantly, which increases the labor of the staff and reduces the work efficiency. In addition, since the staff needs to put their hands under the hydraulic press when putting in and taking out the workpiece, there will be some potential safety risks, including crushing.
