Description

Technical Field

[0001] The utility model relates to the technical field of flywheel casting, in particular to a flywheel casting mould which can be adapted to various models. Background Art

[0002] As an indispensable energy storage element in mechanical systems, the core function of flywheels is to achieve dynamic balance and regulation of kinetic energy through their large rotational inertia. During the machine operation cycle, when the speed increases, the flywheel stores excess energy by increasing its kinetic energy; conversely, when the speed decreases, the flywheel releases the previously stored energy to smooth out speed fluctuations during mechanical operation and ensure smoothness and continuity of power output.

[0003] In view of the specific needs of different mechanical equipment, the specifications and designs of flywheels are diverse, covering different sizes, shapes and moments of inertia. For different types of flywheels, special casting molds need to be customized to ensure that the flywheel meets the requirements of specific applications. However, the development and production of each new mold is accompanied by high costs, including material costs, design costs, processing costs, and subsequent maintenance and commissioning expenses. In addition, the storage, management and replacement of molds also increase the complexity of the production process and operating costs. For large-scale manufacturing industries, the large number of molds undoubtedly increases the difficulty of cost control and reduces production efficiency. Utility Model Content

[0004] The utility model provides a flywheel casting mold that can be adapted to various models, and can solve the problem that special casting molds for flywheels of different models need to be customized respectively, and there are many molds, which leads to high production costs and low production efficiency.

[0005] This application provides the following technical solutions:

[0006] A flywheel casting mold that can be adapted to various models includes a base plate, an upper mold is provided on the upper end surface of the base plate, and a lower mold is provided on the lower end surface of the base plate. It is characterized in that an annular protrusion is provided on the lower mold, and a detachably connected annular connecting block is provided on the annular protrusion, and the outer wall of the annular connecting block corresponds to the inner wall of the annular protrusion.

[0007] Beneficial effects: The annular connection block can be replaced according to the specific requirements of different types of flywheels, allowing the mold to adapt to flywheels of different sizes and shapes without replacing the entire mold, thereby improving the adaptability, compatibility and economy of the mold. The outer wall of the annular connection block corresponds to the inner wall of the annular protrusion, ensuring the positioning accuracy and stability of different types of flywheels during casting. At the same time, the detachable annular connection block can be quickly replaced, which improves the flexibility of the production line, reduces downtime and improves production efficiency.

[0008] Furthermore, an outer wall of the annular connection block is provided with an external thread, and an inner wall of the annular protrusion of the lower mold is provided with an internal thread, and the annular connection block and the annular protrusion are detachably connected through threaded cooperation.

[0009] Beneficial effects: Threaded connection is more convenient for installation and disassembly, no connecting parts are required, which facilitates component management and reduces costs. At the same time, it can provide a stable connection when subjected to external forces or vibrations, prevent components from loosening during production, and ensure the safety and reliability of the casting process.

[0010] Furthermore, the annular connecting block is detachably connected to the annular protrusion of the lower mold via bolts or pins.

[0011] Beneficial effects: The bolts and pins can provide a stable connection, ensuring that the annular connecting block and the annular protrusion of the lower mold will not be relatively displaced during the casting process, thereby maintaining the integrity and accuracy of the mold.

[0012] Further, the upper mold is detachably mounted on the bottom plate; and / or, the lower mold is detachably mounted on the bottom plate.

[0013] Beneficial effects: The upper and lower molds are designed to be detachable, so that different parts of the mold can be replaced independently, which improves the modularity of the mold and facilitates rapid adjustment according to different product requirements. Compared with integral molds, modular design can reduce the total cost of ownership of the mold because there is no need to design and manufacture a new mold for each product, only to replace or adjust specific modules.

[0014] Furthermore, the base plate is provided with a groove, the groove wall of the groove is provided with an internal thread, the outer periphery of the upper mold or the lower mold is provided with an external thread corresponding to the internal thread of the groove wall, and the upper mold or the lower mold is installed in the groove of the base plate through threaded matching.

[0015] Beneficial effects: Ensure accurate alignment between the upper die, lower die and base plate, ensure dimensional accuracy and geometry during flywheel casting, and prevent mold displacement in high-pressure casting environments. Allows the use of upper or lower dies of different specifications to meet the casting needs of different flywheel models. By replacing mold parts of different sizes, flexible response to changing production tasks can be achieved.

[0016] Furthermore, the upper die or the lower die is mounted on the base plate by bolts or pins.

[0017] Benefits: The bolts or pins provide a stable connection, ensuring that the mold will not loosen or separate during the high pressure casting process.

[0018] Furthermore, the base plate includes an upper template and a lower template, the upper template is detachably mounted on the front of the upper template, the lower template is detachably mounted on the front of the lower template, and the back of the upper template is connected to the back of the lower template by bolts.

[0019] Beneficial effects: The independent design of the upper and lower molds, as well as the detachable installation of the upper and lower molds, allow different parts of the mold to be replaced and maintained independently, improving the modularity of the mold and facilitating rapid adjustment of the mold configuration according to different product requirements. When the upper or lower mold is worn or damaged, the part can be replaced directly without replacing the entire mold, reducing maintenance costs and downtime, and improving production efficiency.

[0020] Furthermore, a plurality of lower dies are provided on the bottom plate, and the annular connecting blocks provided on the respective lower dies have different circumferential thicknesses.

[0021] Beneficial effect: Annular connecting blocks of different thicknesses can meet the casting requirements of flywheels of different models or sizes. The size of the mold can be adjusted by replacing annular connecting blocks of different thicknesses without replacing the entire lower mold, which improves production flexibility and mold adaptability.

[0022] Furthermore, the end surface of the annular connecting block is flush with the end surface of the annular protrusion.

[0023] Beneficial effects: The flushness of the end faces ensures the precise alignment of the mold in the closed state, reduces flash and burrs caused by uneven mold gaps, and helps improve the dimensional accuracy and surface finish of the casting.

[0024] Furthermore, a pouring channel is provided on the bottom plate.

[0025] Beneficial effects: The runner is used to guide the molten metal from the gate into the mold cavity to form the desired casting. BRIEF DESCRIPTION OF THE DRAWINGS
