Description
Technical Field
[0001] The utility model relates to the technical field of iron and steel castings, in particular to a die sleeve and die core structure for iron and steel castings. Background Art
[0002] A die sleeve and die core structure for iron and steel castings is a die system used in the iron and steel casting process. It consists of two parts, a die sleeve and a die core, and is mainly used to form the external contour and internal cavity of the casting.
[0003] Traditional dies are prone to deformation under high temperature and high pressure conditions, which affects the quality of the casting and the service life of the die. Due to the limitations of die design and manufacturing, traditional dies often fail to meet the requirements of high precision, resulting in large deviations in the size and shape of the casting. The disassembly and replacement of traditional dies are relatively complex, and the maintenance cost is high, which affects the production efficiency. Therefore, developing a new type of die sleeve and die core structure for iron and steel castings to solve the above problems, improve the quality of castings and production efficiency, and reduce the maintenance cost has become a technical problem to be solved in the casting industry. Summary of the Utility Model
[0004] To solve the above technical problems, the utility model provides a die sleeve and die core structure for iron and steel castings.
[0005] The utility model is realized by the following technical solutions: A die sleeve and die core structure for iron and steel castings includes a die sleeve. A connection section is connected to the upper surface of the die sleeve. An installation groove is provided on the inner wall of the die sleeve. A die core is fixedly connected to the inner wall of the installation groove. An upper boring hole is provided in the middle of the upper part of the connection section, and a plurality of lower boring holes are provided in the lower part of the connection section. A connection fixing bolt is provided in the upper boring hole, and a locking mechanism is provided in the lower boring holes.
[0006] Through the above technical solutions, the die sleeve, the die core, and the connection section form the basic framework of the die, providing the external shape for the casting. Through their connection, the upper and lower parts of the die are ensured to be aligned and closely fitted. The installation groove is used to fix the die core, ensuring the correct position of the die core in the die. Through mechanical connection or fitting fixation, it will not move in the die. The connection fixing bolt is used to connect the connection section and other components, providing a stable connection point. Through bolt connection, the connection section or other related components can be conveniently disassembled and replaced. These lower boring holes are used for further assembly and fixation, ensuring the precise alignment of each part of the die. A locking mechanism is provided in the lower boring holes, facilitating the installation and disassembly of the die core and the connection section.
[0007] As a further improvement of the above solution, an equally divided process lug is fixedly connected to the bottom of the die core.
[0008] Through the above technical solution, the equal - division process lugs ensure the correct position and stability of the die core in the mold. Through the equal - division design, the evenly distributed support points can prevent the die core from deforming or moving during the casting process.
[0009] As a further improvement of the above solution, the mold sleeve includes a fixed mold sleeve, and several A - shaped reinforcing ribs are fixedly connected to the upper surface of the fixed mold sleeve.
[0010] Through the above technical solution, the fixed mold sleeve and the A - shaped reinforcing ribs provide additional support and fixation, enhancing the strength of the overall structure. By increasing the support structure, the stress can be dispersed, preventing the mold from deforming under high - temperature and high - pressure conditions.
[0011] As a further improvement of the above solution, the die core includes a die - core fixing ring, and several B - shaped reinforcing ribs are fixedly connected to the lower surface of the die - core fixing ring, and the die - core fixing ring is adapted to the B - shaped reinforcing ribs.
[0012] Through the above technical solution, the die - core fixing ring and the B - shaped reinforcing ribs further enhance the stability of the die core. Through the design of the fixing ring and the reinforcing ribs, the pressure during the casting process can be effectively resisted, maintaining the shape and position of the die core unchanged.
[0013] As a further improvement of the above solution, the installation groove includes an upper cylindrical section and a lower conical - frustum section, and the lower conical - frustum section is smaller at the top and larger at the bottom.
[0014] Through the above technical solution, the upper cylindrical section and the lower conical - frustum section can achieve precise positioning and fixation of the die core.
[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0016] The present utility model can ensure the dimensional and shape accuracy of the casting by setting precise mold sleeve and die - core designs, reducing the scrap rate. By using various fixing and connecting methods such as bolts and locking mechanisms, the overall stability of the mold is enhanced, preventing deformation or displacement during the casting process. Through the design of equal - division process lugs and reinforcing ribs, the stress can be effectively dispersed, reducing mold fatigue and extending the service life of the mold. This structural design can withstand high - temperature and high - pressure conditions during the casting process, ensuring the reliable performance of the mold in harsh environments. Due to the high stability and precision of the mold, the defective products during the casting process can be reduced, improving production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
