Description

Technical Field

[0001] The utility model relates to the technical field of quality ring casting, in particular to a quality ring double-layer casting mold. Background Art

[0002] As a crucial component in a mechanical system, the quality ring (also known as the inertia ring) mainly functions to endow the flywheel with the necessary moment of inertia, thereby achieving efficient storage and release of kinetic energy. The quality ring is usually produced by a casting process. First, a mold with the same structure and shape as the quality ring is pre-made, and then the mold is placed in the sand mold. Thus, a cavity with the same structural dimensions as the quality ring is formed in the sand mold. Then, a fluid liquid is poured into the cavity, and after the liquid cools and solidifies, a quality ring with the same external shape structure as the mold is formed. Currently, a set of quality ring casting molds can only produce quality rings of a single specification. However, with the different requirements of different mechanical equipment, the structural dimensions of the quality rings are different, which leads to a large number of molds, high mold opening costs, reduced production efficiency, and increased production costs. Content of the Utility Model

[0003] The utility model provides a quality ring double-layer casting mold, which can solve the problems of a large number of molds, high mold opening costs, reduced production efficiency, and increased production costs.

[0004] The present application provides the following technical solutions:

[0005] The quality ring double-layer casting mold includes a bottom plate. A first casting template is provided on the upper end surface of the bottom plate. An isolation plate template is provided between the first casting template and the bottom plate. A second casting template is provided on the lower end surface of the bottom plate. The outer peripheral dimension of the isolation plate template is larger than those of the first casting template and the second casting template, and the inner peripheral dimension of the isolation plate template is smaller than those of the first casting template and the second casting template.

[0006] Beneficial Effects: The design of the isolation plate template ensures the independence of the upper and lower layers of casting sand molds, avoids the improper flow of molten metal between the two layers, helps improve the dimensional accuracy and surface quality of the castings, and reduces defects. By simultaneously producing two quality rings in one casting process, the production efficiency is significantly improved, the time for repeatedly setting up the molds and sand molds is reduced, and the production cycle is accelerated. Double-layer casting reduces the number of mold uses, reduces the mold wear and replacement frequency, and also reduces the sand material and labor costs, thereby reducing the overall production cost. This kind of mold can also allow the simultaneous production of quality rings of different specifications, improving the flexibility and adaptability of the production line.

[0007] Furthermore, the first casting template and the second casting template are of a symmetrical or asymmetrical structure.

[0008] Beneficial effects: When the first casting template and the second casting template are of symmetrical structure, the quality rings cast using the first casting template and the second casting template have the same specifications, which can effectively improve production efficiency. When the first casting template and the second casting template are of asymmetrical structure, the quality rings cast using the first casting template and the second casting template have different specifications, enabling the simultaneous production of quality rings of different specifications, and improving the flexibility and adaptability of the production line.

[0009] Further, the separator plate template is of annular structure, and an outwardly extending protrusion is provided on the outer periphery of the separator plate template.

[0010] Beneficial effects: The outwardly extending protrusion provides a positioning point, ensuring the precise position of the separator plate in the sand mold, enhancing the stability and strength of the sand mold structure, reducing the risk of displacement that may occur during pouring, and improving the dimensional accuracy and quality of the casting.

[0011] Further, an outer annular ring is detachably connected to the lower end of the outer periphery of the first casting template, and an inner annular ring is detachably connected to the lower end of the inner periphery of the first casting template. The outer annular ring, the inner annular ring and the first casting template cooperate to form a separator plate template.

[0012] Further, the outer annular ring and the inner annular ring are detachably connected to the bottom plate by pins or bolts.

[0013] Beneficial effects: The detachable connection design of the outer annular ring and the inner annular ring enables different parts of the mold to be independently replaced and maintained, improving the modularity of the mold, facilitating the rapid adjustment of the mold configuration according to different product requirements, and increasing the production flexibility and the adaptability of the mold.

[0014] Further, the separator plate template is of rectangular structure.

[0015] Beneficial effects: The separator plate template of rectangular structure enables the separator plate to have more contact points and straight edges in the sand box, which helps to improve the stability of the separator plate and reduce the risk of displacement during pouring. At the same time, during the placement of the separator plate, it is more convenient for precise alignment and positioning, ensuring the quality of the casting.

[0016] Further, a runner template is provided on the bottom plate.

[0017] Beneficial effects: The runner template is used to guide the molten metal from the gate into the mold cavity to form the required casting.

[0018] Further, the separator plate template is used to form a cavity for setting the separator plate. The separator plate is a sand core, and the sand core is formed by covering a mixture of sand and binder.

[0019] Beneficial effects: During the process of casting the quality ring, the sand core (separator plate) is placed between the upper and lower layers of casting sand molds, playing a role in isolation to ensure that the upper and lower layers of castings do not interfere with each other during the pouring process and maintain independent forming spaces.

[0025] The marks in the attached drawings of the specification include: bottom plate 1, first casting template 2, separator plate template 3, protrusion 301, outer annular ring 302, inner annular ring 303, second casting template 4, separator plate 6, limiting part 601, and runner template 7.

[0026] Embodiment 1

[0027] As Figures 1 to 3 shown, the double-layer pouring mold for the quality ring includes a bottom plate 1. On the upper end face of the bottom plate 1, there are two first casting templates 2. Between the first casting template 2 and the bottom plate 1, there is a separator plate template 3. The separator plate template 3 is of an annular structure, and there is a protrusion 301 extending outward on the outer periphery of the separator plate template 3. On the lower end face of the bottom plate, there are two second casting templates 4. The positions of the two second casting templates 4 correspond to the positions of the first casting templates 2 respectively. The outer peripheral diameter of the separator plate template 3 is larger than the outer peripheral diameters of the first casting template 2 and the second casting template 4, and the inner peripheral diameter of the separator plate template 3 is smaller than the inner peripheral diameters of the first casting template 2 and the second casting template 4. The first casting template 2 and the second casting template 4 are selected to be symmetric or asymmetric structures according to actual production requirements. In this embodiment, the first casting template 2 and the second casting template 4 are of an asymmetric structure, and the height of the first casting template 2 is less than the height of the second casting template 4. There is a runner template 7 on the bottom plate 1, and the runner template 7 is used to make runners on the sand box.

[0028] The separator plate template 3 is used to form a cavity for arranging the separator plate 6. There is a limiting part 601 extending outward on the outer periphery of the separator plate 6. The separator plate 6 is a sand core, and the sand core is made by covering a mixture of sand and binder.

[0029] When casting the quality ring, the sand mold cavity of the first casting is made in the upper sand box through the first casting template 2, and the separator plate sand mold cavity is made in the upper sand box through the separator plate template 3. The separator plate 6 is placed in the separator plate sand mold cavity of the upper sand box. The limiting part 601 of the separator plate 6 is located in the sand mold cavity corresponding to the protrusion 301 of the separator plate template 3, so that the separator plate 6 is circumferentially limited in the upper sand box. The sand mold cavity of the second casting is made in the lower sand box through the second casting template 4. The upper sand box and the lower sand box are closed. The separator plate 6 is located between the sand mold cavity of the first casting and the sand mold cavity of the second casting, preventing the two sand mold cavities from directly communicating. The sand mold cavity of the first casting and the sand mold cavity of the second casting are respectively communicated with the runner.

[0030] Embodiment 2

[0031] The difference between this embodiment and Embodiment 1 is that the separator plate template 3 is of a rectangular structure, and a rectangular hole is provided in the middle of the rectangular structure. If the separator plate template 3 is of a square structure, the outer peripheral single-side side length of the separator plate template 3 is greater than the outer peripheral diameter of the first casting template 2 and the second casting template 4, and the inner peripheral diagonal length of the separator plate template 3 is less than the inner peripheral diameter of the first casting template 2 and the second casting template 4.

[0032] Embodiment 3

[0033] As Figure 4 shown, the difference between this embodiment and Embodiment 1 is that an outer annular ring 302 is detachably connected to the lower end of the outer periphery of the first casting template 2, and an inner annular ring 303 is detachably connected to the lower end of the inner periphery of the first casting template 2. The outer annular ring 302 and the inner annular ring 303 cooperate with the first casting template 2 to form the separator plate template 3. The outer annular ring 302 and the inner annular ring 303 are detachably connected to the bottom plate 1 by pins or bolts. The outer periphery of the outer annular ring 302 is provided with a protrusion 301 extending outward.
