Description

Technical Field

[0001] The utility model relates to the technical field of casting tooling, in particular to a casting mold capable of simultaneously casting a flywheel and an inertia ring. Background Art

[0002] In some precision mechanical systems, it may be necessary to adjust the system's moment of inertia and energy requirements at different stages of operation. The combined use of a flywheel and an inertia ring is a common way to adjust and optimize the dynamic performance and stability of a mechanical system. The dynamic characteristics of the system can be adjusted at different stages of operation to achieve more optimized performance. However, the production of flywheels and inertia rings is independent of each other, and each requires its own special mold for casting. The production process is cumbersome, so there is an urgent need for a casting mold that can simultaneously cast flywheels and inertia rings to simplify the operation process. Utility Model Content

[0003] The utility model provides a casting mold capable of casting a flywheel and an inertia ring at the same time, which can solve the technical problem that the existing casting mold can only cast the flywheel and the inertia ring separately and the production operation process is complicated.

[0004] This application provides the following technical solutions:

[0005] A casting mold capable of simultaneously casting a flywheel and an inertia ring comprises a base with a square structure, an equal number of flywheel templates and inertia ring templates fixedly arranged on the end surface of the base, wherein the number of flywheel templates is an odd number, a first runner template is fixedly arranged between several flywheel templates, a second runner template is fixedly arranged between several inertia ring templates, a gate template is fixedly arranged on the first runner template and the second runner template, respectively, and the distance between the gate template and each inertia ring template or flywheel template is equal.

[0006] Beneficial effects:

[0007] 1. Improve production efficiency: Several flywheel templates and inertia ring templates are fixedly set on the end face of the base at the same time, so that the flywheel and the inertia ring can be cast simultaneously. The casting links are no longer independent of each other, which is conducive to improving the production efficiency of the production site. The purpose of setting the same number of flywheel templates and inertia ring templates is that the production site requires one flywheel to be used in combination with one inertia ring.

[0008] 2. Ensure the compactness of the overall structure of the mold: The number of flywheel templates is an odd number, so that after the flywheel template is fixed, there will be some empty area on the base of the square structure. This area is used to fix the same number of inertia ring templates, making the overall structure of the mold compact.

[0009] 3. It is conducive to maintaining the consistency of molded products: the gate, the first runner and the second runner formed by the gate template, the first runner template and the second runner template are at the same distance from the gate to each inertia ring or flywheel. When the molten metal is poured into the gate, the molten metal can fill the cavities for casting multiple flywheels and multiple inertia rings at the same time, which is conducive to maintaining the consistency of the molded products and also helps to improve production efficiency.

[0010] Furthermore, as an improvement, the number of the flywheel templates and the inertia ring templates are both 3, and the 3 flywheel templates are arranged in a triangle.

[0011] Beneficial effect: The three flywheel templates arranged in a triangle leave about 1 / 4 area of ​​the square structure base vacant, and three inertia ring templates are fixedly set in this area, which is conducive to ensuring the compactness of the overall structure of the template.

[0012] Further, as an improvement, the number of the flywheel templates and the inertia ring templates is 5, and the 5 flywheel templates are arranged in a pentagonal manner, wherein one flywheel template is located on the center line of the base, and the inertia ring template is divided into two groups and arranged on both sides of the center line of the base.

[0013] Beneficial effect: When the number of flywheel templates and inertia ring templates is 5, in order to ensure the overall compact structure, one flywheel template is required to be located on the center line of the base, so that the base is bounded by the flywheel template, and a part of the upper and lower areas can be left free to arrange the inertia ring template.

[0014] Furthermore, as an improvement, hanging holes are fixedly provided at the edges of the base, and the hanging holes are internal threaded holes.

[0015] Beneficial effect: The lifting holes fixed around the base are used in conjunction with lifting equipment such as cranes, which is beneficial to improving the flexibility of the mold. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Figure 1 It is a top view of the first embodiment of the casting mold for simultaneously casting a flywheel and an inertia ring of the utility model;

[0017] Figure 2 It is a top view of a second embodiment of a casting mold for simultaneously casting a flywheel and an inertia ring according to the utility model. DETAILED DESCRIPTION

[0018] The following is further described in detail through specific implementation methods:

[0019] The marks in the drawings of the specification include: base 1, lifting hole 11, center line 12, diagonal line 13, flywheel template 2, first runner template 3, main runner template 31, branch runner template 32, gate template 33, inertia ring template 4, and second runner template 5.

[0020] Embodiment 1

[0021] like Figure 1 As shown, a casting mold for simultaneously casting a flywheel and an inertia ring includes a base 1 with a square structure, and three flywheel templates 2 are fixedly arranged on the end surface of the base 1; hanging holes 11 are fixedly arranged at the edges of the base 1, and in this embodiment, the hanging holes 11 are internal threaded holes; the flywheel template 2 is a circular protrusion as a whole, and the three flywheel templates 2 are arranged in a triangle with their center as the reference, so that about 1 / 4 of the area of ​​the square structure base 1 is left vacant.

[0022] Regarding the design of the runner, a first runner template 3 is fixedly set between the three flywheel templates 2. The first runner template 3 includes a main runner template 31 and three branch runner templates 32 integrally formed with the main runner template 31. The three branch runner templates 32 are respectively connected to the outer circles of the three flywheel templates 2. A gate template 33 is fixedly set on the main runner template 31. Note that the distance from the gate template 33 to each flywheel template 2 along the first runner template 3 is equal, so that the molten metal can be freely flowed into the three cavities for casting flywheels at the same time after being poured into the gate.

[0023] In the 1 / 4 area of ​​the base 1 where the flywheel template 2 is not set, three inertia ring templates 4 of the same number as the flywheel template 2 are fixedly set. The purpose of setting the same number of flywheel templates 2 and inertia ring templates 4 is that the production site requires that one flywheel needs to be used in combination with one inertia ring. The inertia ring template 4 is a circular ring-shaped protrusion. The three inertia ring templates 4 are arranged in an equal triangle with their center as the reference. A second runner template 5 is fixedly set between the three inertia ring templates 4. The only difference between the second runner template 5 and the first runner template 3 is that the main runner template 31 is not set, and the gate template 33 is set at the central intersection of the three branch runner templates 32. It is necessary to ensure that the gate on the second runner template 5 is at an equal distance from the branch runner template 32 to the three inertia ring templates 4.

[0024] Sand casting is a common metal casting process in modern technology. This process uses sand in a sand box as the material. The sand is first squeezed through a mold to form a concave cavity in the sand, and then the molten metal is poured into the cavity. After cooling and solidification, the desired casting will be formed.

[0025] The specific application process of the sand casting process using the casting mold capable of simultaneously casting the flywheel and the inertia ring is as follows:

[0026] When in use, the sand in the sand box is squeezed from top to bottom with a mold so that a concave cavity simulating a flywheel, an inertia ring, a runner and a gate is formed on the surface of the sand. Then, the molten metal is poured into the gates on the first runner template 3 and the second runner template 5 respectively. The molten metal flows to and fills the cavities simulating the flywheel and the inertia ring through the gate, the main runner and the branch runner in turn. After the molten metal is cooled and solidified, a flywheel and an inertia ring are formed. Then, they are peeled off from the sand and subjected to subsequent processing steps such as cleaning and polishing to finally form a flywheel and inertia ring of qualified quality.

[0027] This solution not only achieves the effect of casting the flywheel and the inertia ring at the same time by reasonably designing the number and position of the flywheel template 2 and the inertia ring template 4 on the square base 1, but also fully considers the steps of pouring multiple cavities at the same time, which improves production efficiency and helps to maintain product consistency.

[0028] Embodiment 2

[0029] The difference between this embodiment and the first embodiment is that Figure 2 As shown, the number of flywheel templates 2 and inertia ring templates 4 are both 5, and the 5 flywheel templates are arranged in a pentagonal pattern with their centers as references, wherein the center of one flywheel template 2 is located on the center line 12 of the base 1, so that the square base 1 is bounded by the flywheel template 2, and a part of the upper and lower areas are left free to set the inertia ring template 4, and the 5 inertia ring templates 4 are divided into two groups and arranged on both sides of the center line 12 of the base 1, one group includes 3 inertia ring templates 4 arranged in an equal triangle as in the first embodiment, and the other group includes 2 inertia ring templates 4, and the centers of the two inertia ring templates 4 are located on the diagonal 13 of the base 1. While making the overall layout compact, the distance between the inertia ring template 4 and the flywheel template 2 is also widened as much as possible, so that the subsequent casting process of the flywheel and the inertia ring does not interfere with each other.

[0030] The above is only an embodiment of the utility model. The utility model is not limited to the field involved in this implementation case. The common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the utility model, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
