Description

Technical Field

[0001] This application belongs to the technical field of castings, and particularly relates to a casting body with an annular structure and a casting mold. Background Art

[0002] Due to the effects of epoxy resin such as anti-electromagnetic interference and insulation, it is then applied in some special scenarios. For example, a casting body made of epoxy resin is used as a projectile, which includes a casting body and an annular structure provided at one end of the casting body, and the two are connected together by casting.

[0003] During the launching operation, the projectile moves in a straight line at high speed under the action of a powerful driving force, and then the projectile is quickly launched to the designated position. However, since the annular structure and the casting body are connected together by casting, when the projectile is impacted by the powerful driving force, it will directly cause the annular structure to separate from the casting body, and then the casting or the annular structure may cause harm to the surrounding equipment and personnel, thus affecting the safety of the casting body. In addition, the existing casting molds are usually disposable and cannot be recycled, resulting in waste of resources and increasing the production cost of the casting body. Utility Model Content

[0004] This application provides a casting body with an annular structure to increase the connection stability between the annular structure and the casting body itself, thereby increasing the safety of the casting body.

[0005] The technical solution adopted by this application is as follows:

[0006] A casting body with an annular structure includes an annular body and a casting body itself. A reinforcing part protruding or recessed from the inner wall is provided inside the annular body. The casting body itself has a connecting section, and the connecting section is formed by the casting material poured inside the annular body and is formed on the reinforcing part.

[0007] By adopting the above technical solution, since a reinforcing part protruding or recessed from the inner wall is provided inside the annular body, and the connecting section is formed by the casting material poured inside the annular body and is formed on the reinforcing part, the connection stability between the casting body itself and the annular body is increased, and the situation where the annular body separates from the casting body itself when the casting body moves in a straight line under the action of a powerful driving force is avoided, thereby avoiding the situation where the casting body itself and the annular body may cause harm to the surrounding equipment and personnel, and greatly improving the safety of the casting body.

[0008] Optionally, the reinforcing part is a groove-shaped structure provided inside the annular body, and the groove-shaped structure extends along the circumferential direction of the annular body;

[0009] Alternatively, the reinforcing portion is a thread groove provided on the inner wall of the ring body, and the thread groove extends spirally along the inner wall of the ring body.

[0010] By adopting the above technical solution, since the reinforcing portion is a groove-shaped structure provided on the inner wall of the ring body, the casting material poured into the ring body will be formed on the inner wall of the groove-shaped structure after molding, so as to increase the connection stability between the casting body and the ring body, and at the same time reduce the production difficulty of the ring body, thereby reducing the production cost of the casting body.

[0011] Since the reinforcing portion is a thread groove provided on the inner wall of the ring body, the production difficulty of the ring body is further reduced, and at the same time, the connection area between the casting body and the reinforcing portion is further increased, thereby further increasing the connection stability between the casting body and the ring body.

[0012] Optionally, the reinforcing portion is a protrusion provided on the inner wall of the ring body, and a plurality of the protrusions are arranged at intervals along the circumferential direction of the ring body;

[0013] Alternatively, the reinforcing portion is a rib provided on the inner wall of the ring body, and the rib extends along the circumferential direction of the ring body.

[0014] By adopting the above technical solution, since the reinforcing portion is a protrusion provided on the inner wall of the ring body, the casting body is formed outside the protrusion, so as to increase the connection stability between the casting body and the ring body.

[0015] Since the reinforcing portion is a rib provided on the inner wall of the ring body and the rib extends along the circumferential direction of the ring body, the connection area between the reinforcing portion and the casting body is further increased, so as to further increase the connection stability between the casting body and the ring body, and further increase the safety when applying a strong driving force to the casting body to make the casting body move linearly.

[0016] The present application also discloses a casting mold, so that the casting mold can be recycled, avoiding waste of resources and reducing the production cost of the casting body.

[0017] A casting mold for molding the above-mentioned casting body, comprising a first mold body, a second mold body and a connection structure for connecting the first mold body and the second mold body, and the first mold body and the second mold body together form a molding cavity with an opening at one end.

[0018] By adopting the above technical solution, when using the casting mold in the present application, first install the ring body on the first mold body or the second mold body, then dock the first mold body and the second mold body and use the connecting structure to connect the first mold body and the second mold body, so that the first mold body and the second mold body jointly form a molding cavity, and then pour the casting material into the molding cavity through the cavity opening of the molding cavity, so that the casting material cools and forms in the molding cavity and forms together with the ring body. After the casting material solidifies, remove the connecting structure, then separate the first mold body and the second mold body and take out the formed casting body to complete the production of the casting body.

[0019] Since the first mold body and the second mold body are detachable, the casting mold in the present application can be recycled, so as to reduce the production cost of the casting material and avoid waste of resources at the same time.

[0020] Optionally, both the first mold body and the second mold body have a first end and a second end opposite to the first end. The cavity opening of the molding cavity is located at the first end. There are two sets of connecting structures which are respectively located at the first end and the second end. Each set of connecting structures includes a bolt pair passing through the first mold body and the second mold body.

[0021] By adopting the above technical solution, since there are two sets of connecting structures which are respectively located at the first end and the second end, the connection stability between the first mold body and the second mold body is increased, so as to increase the sealing performance of the molding cavity, and then improve the molding effect of the casting material; since the connecting structure includes a bolt pair passing through the first mold body and the second mold body, the disassembly and assembly difficulty of the first mold body and the second mold body is improved, so as to improve the production efficiency of the casting body.

[0022] Optionally, both the first mold body and the second mold body have sealing planes in contact with each other, and the axial direction of the bolt pair is perpendicular to the sealing plane.

[0023] By adopting the above technical solution, since the circumferential direction of the bolt pair is perpendicular to the sealing plane, the fixing effect of the bolt pair on the first mold body and the second mold body is increased, so as to increase the connection stability and sealing performance between the first mold body and the second mold body, and further ensure the production quality of the casting body.

[0024] Optionally, the first mold body is provided with a sealing groove along its circumferential direction, and the second mold body is provided with a sealing rib extending into the sealing groove along its circumferential direction.

[0025] By adopting the above technical solution, since the first mold body is provided with a sealing groove and the second mold body is provided with sealing ribs arranged along its circumferential direction, after the first mold body and the second mold body are assembled together, the sealing ribs extend into the sealing groove, so as to increase the connection sealing performance between the first mold body and the second mold body, thereby increasing the sealing performance of the molding cavity. At the same time, the cooperation between the sealing ribs and the sealing groove can also position the first mold body and the second mold body, so as to reduce the assembly difficulty of the first mold body and the second mold body.

[0026] Optionally, the sealing groove and / or the sealing ribs are provided with a sealing layer, so that the sealing ribs contact the groove wall of the sealing groove through the sealing layer.

[0027] By adopting the above technical solution, since the sealing groove and / or the sealing ribs are provided with a sealing layer, the connection sealing performance between the first mold body and the second mold body is further increased, so as to further increase the sealing performance of the molding cavity, and further improve the molding effect on the casting body.

[0028] Optionally, the first mold body and / or the second mold body are both provided with a reference part for referring to the casting amount.

[0029] By adopting the above technical solution, since the first mold body and / or the second mold body are both provided with a reference part for referring to the casting amount, the casting difficulty of the casting material is reduced, and the situation of too much or too little casting of the casting material is avoided, so as to improve the production quality of the casting body and ensure the quality stability of the casting body.

[0030] Optionally, the reference part is a first notch provided on the first mold body and a second notch provided on the second mold body, and the first notch and the second notch form a reference notch;

[0031] Or, the reference part is a reference scale provided on the first mold body and / or the second mold body.

[0032] By adopting the above technical solution, since the first notch and the second notch form a reference notch, on the one hand, the reference notch can be used by the staff as a reference when casting the casting material, so as to facilitate the staff to cast the casting material. On the other hand, when separating the first mold body and the second mold body, the staff can also put their hands into the reference notch, so as to facilitate the separation of the first mold body and the second mold body.

[0033] Since the reference part is a reference scale provided on the first mold body and / or the second mold body, the reference of the casting amount is more intuitive, so as to further facilitate the accurate casting of the casting body. In addition, the reference scale can also be used as a reference for the installation position of the ring body, so as to increase the accuracy of the ring body installation position, and further ensure the production quality of the casting body.

[0034] Due to the adoption of the above technical solution, the beneficial effects obtained by this application are as follows:

[0035] 1. The casting body in this application includes a ring body and a casting body main body. A reinforcing part that protrudes or recesses from the inner wall is provided inside the ring body. The casting body main body has a connecting section, which is formed by the casting material poured inside the ring body and is formed on the reinforcing part, thereby increasing the connection stability between the casting body main body and the ring body. When the casting body moves linearly under a strong driving force, the situation of separation between the ring body and the casting body main body is avoided, thus avoiding the situation where the casting body main body and the ring body may cause harm to surrounding equipment and personnel, and greatly improving the safety of the casting body.

[0036] 2. The reinforcing part in this application is a groove-shaped structure provided inside the ring body, and the groove-shaped structure extends along the circumferential direction of the ring body.

The inside of the annular body 1 is provided with a reinforcing portion 11 protruding or recessed from its inner wall. The casting body main body 2 has a connecting section, and the connecting section is formed by the casting material poured inside the annular body 1 and is formed on the reinforcing portion 11.

[0056] Since the inside of the annular body 1 is provided with a reinforcing portion 11 protruding or recessed from its inner wall, and the connecting section is formed by the casting material poured inside the annular body 1 and is formed on the reinforcing portion 11, the connection stability between the casting body main body 2 and the annular body 1 is increased.

[0057] This application does not make specific limitations on the structure of the reinforcing portion 11, and it can adopt any one of the following embodiments:

[0058] Embodiment 1: In this embodiment, the reinforcing portion 11 is a groove-shaped structure provided inside the annular body 1. The groove-shaped structure extends along the circumferential direction of the annular body 1. Then, after the casting material poured inside the annular body 1 is formed, it will be formed on the inner wall of the groove-shaped structure, so as to increase the connection stability between the casting body main body 2 and the annular body 1, and at the same time reduce the production difficulty of the annular body 1, so as to reduce the production cost of the casting body.

[0059] Preferably, a plurality of groove-shaped structures are arranged along the axial direction of the annular body 1 to further increase the connection area between the casting body main body 2 and the annular body 1, thereby further increasing the connection stability between the casting body main body 2 and the annular body 1, and further increasing the safety of the casting body when it moves linearly under a strong driving force.

[0060] It should be noted that the groove-shaped structure can be a closed ring arranged along the circumferential direction of the annular body 1, or it can also be an arc-shaped structure extending along the circumferential direction of the annular body 1.

[0061] Embodiment 2: In this embodiment, the reinforcing part 11 is a thread groove provided on the inner wall of the ring body 1. The thread groove extends spirally along the inner wall of the ring body 1, thereby further reducing the production difficulty of the ring body 1. At the same time, the connection area between the casting body 2 and the reinforcing part 11 is further increased, and thus the connection stability between the casting body 2 and the ring body 1 is further increased.

[0062] Embodiment 3: In this embodiment, referring to Figure 2 and Figure 3 , the reinforcing part 11 is a protrusion provided on the inner wall of the ring body 1. A plurality of protrusions are arranged at intervals along the circumferential direction of the ring body 1. Then, the casting body 2 is formed outside the protrusions to increase the connection stability between the casting body 2 and the ring body 1.

[0063] Embodiment 4: In this embodiment, referring to Figure 4 and Figure 5 , the reinforcing part 11 is a rib provided on the inner wall of the ring body 1. The rib extends along the circumferential direction of the ring body 1, thereby further increasing the connection area between the reinforcing part 11 and the casting body 2, so as to further increase the connection stability between the casting body 2 and the ring body 1, and further increase the safety when a strong driving force is applied to the casting body to make the casting body move in a straight line.

[0064] Preferably, a plurality of ribs are arranged along the axial direction of the ring body 1 to further increase the connection stability between the casting body 2 and the ring body 1.

[0065] Referring to Figures 6 to 9 , the present application also discloses a casting mold for molding the above-mentioned casting body, including a first mold body 3, a second mold body 4, and a connection structure for connecting the first mold body 3 and the second mold body 4. The first mold body 3 and the second mold body 4 together form a molding cavity with an opening at one end.

[0066] When using the casting mold in the present application, first install the ring body 1 on the first mold body 3 or the second mold body 4, then dock the first mold body 3 and the second mold body 4 and use the connection structure to connect the first mold body 3 and the second mold body 4, so that the first mold body 3 and the second mold body 4 together form a molding cavity. Then, pour the casting material into the molding cavity through the opening of the molding cavity, so that the casting material cools and solidifies in the molding cavity and is formed together with the ring body 1. After the casting material solidifies, remove the connection structure, then separate the first mold body 3 and the second mold body 4 and take out the molded casting body to complete the production of the casting body.

[0067] Since the first mold body 3 and the second mold body 4 are detachable, the casting mold in the present application can be recycled, thereby reducing the production cost of the casting material and avoiding waste of resources at the same time.

[0068] This application does not specifically limit the structure of the connection structure. Preferably, both the first mold body 3 and the second mold body 4 have a first end and a second end opposite to the first end. The orifice of the molding cavity is located at the first end. There are two sets of connection structures, which are respectively located at the first end and the second end.

[0069] It can be understood that through holes for the screw of the bolt pair to pass through are relatively arranged on both the first mold body 3 and the second mold body 4.

[0070] Since there are two sets of connection structures, which are respectively located at the first end and the second end, the connection stability between the first mold body 3 and the second mold body 4 is increased, so as to increase the sealing performance of the molding cavity, and then the molding effect of the casting is improved; since the connection structure includes a bolt pair passing through the first mold body 3 and the second mold body 4, the disassembly and assembly difficulty of the first mold body 3 and the second mold body 4 is increased, so as to improve the production efficiency of the casting body.

[0071] Furthermore, both the first mold body 3 and the second mold body 4 have sealing planes in contact with each other, and the axial direction of the bolt pair is perpendicular to the sealing plane, which further increases the fixing effect of the bolt pair on the first mold body 3 and the second mold body 4, so as to increase the connection stability and sealing performance between the first mold body 3 and the second mold body 4, and further ensure the production quality of the casting body.

[0072] In other embodiments, the connection structure may further include a clamping portion provided on the first mold body 3 and a mating portion provided on the second mold body 4. The clamping portion can be clamped and mated with the mating portion to realize the detachable connection between the first mold body 3 and the second mold body 4; alternatively, the connection structure is an annular structure sleeved outside the first mold body 3 and the second mold body 4.

That is to say, after the first mold body 3 and the second mold body 4 are assembled together, the sealing rib 41 extends into the sealing groove 31 to increase the connection sealing performance between the first mold body 3 and the second mold body 4, so as to increase the sealing performance of the molding cavity. At the same time, the cooperation between the sealing rib 41 and the sealing groove 31 can also position the first mold body 3 and the second mold body 4, so as to reduce the assembly difficulty of the first mold body 3 and the second mold body 4.

[0074] Furthermore, a sealing layer is provided on the sealing groove 31 and / or the sealing rib 41, so that the sealing rib 41 contacts the groove wall of the sealing groove 31 through the sealing layer.

[0075] Since the sealing groove 31 and / or the sealing rib 41 is provided with a sealing layer, the connection sealing performance between the first die body 3 and the second die body 4 is further increased, so as to further increase the sealing performance of the forming cavity, and further improve the forming effect on the casting body.

[0076] Preferably, the groove wall of the sealing groove 31 and the sealing rib 41 are both provided with a sealing layer to further increase the sealing performance between the first die body 3 and the second die body 4.

[0077] The present application does not specifically limit the structure of the sealing layer. Preferably, the sealing layer is a rubber gasket to increase the sealing performance between the first die body 3 and the second die body 4. In other embodiments, the sealing layer can also be a sealing coating applied to the groove wall of the sealing groove 31 and the sealing rib 41.

[0078] In a preferred embodiment, referring to Figure 6 , a reference portion 32 for referring to the pouring amount is provided on the first die body 3 and / or the second die body 4.

[0079] Since a reference portion 32 for referring to the pouring amount is provided on the first die body 3 and / or the second die body 4, the pouring difficulty of the casting is reduced, and the situation of too much or too little pouring amount of the casting is avoided, so as to improve the production quality of the casting body and ensure the quality stability of the casting body. <x
