Description

Technical Field

[0001] The utility model relates to the technical field of molds, and particularly relates to a graphite mold. Background Technique

[0002] A graphite mold is a basic process equipment widely used in industrial production. Its unique physical and chemical properties make it the preferred tool for many manufacturing processes. The wide application of graphite molds mainly benefits from their excellent performance characteristics. Graphite has good thermal conductivity and electrical conductivity, which makes it particularly effective in high-temperature applications.

[0003] Currently, when making gold products into gold bars, generally multiple gold products need to be placed inside a graphite mold and then placed inside a heating device for high-temperature melting. Currently, the graphite mold generally consists of a graphite bin with accommodation grooves on its surface and a cover plate on the top. The main function of the cover plate is to seal the graphite mold during the high-temperature melting process, prevent the gold products from overflowing, and ensure the concentration of heat, thereby improving the melting efficiency and ensuring the quality of the formed gold bars. However, currently, the cover plate is generally directly placed above the graphite bin. When the user picks up the graphite bin and the cover plate with pliers, the cover plate may slide on the surface of the graphite bin and thus fall off, causing unnecessary losses. Therefore, a new type of graphite mold is needed to solve the above problems. Summary of the Invention

[0004] The technical problem to be solved by the utility model is to provide a graphite mold to solve the problem that the cover plate of the existing graphite mold is generally directly placed above the graphite bin, and when the user picks up the graphite bin and the cover plate with pliers, the cover plate may slide on the surface of the graphite bin and thus fall off, causing unnecessary losses.

[0005] To solve the above technical problem, the utility model provides the following technical solutions:

[0006] A graphite mold includes a main mold body, and a cover plate is arranged above the main mold body;

[0007] It further includes a lateral limiting mechanism, and the lateral limiting mechanism is used to limit the position of the cover plate above the main mold body to prevent it from sliding on the horizontal plane.

[0008] Optionally, the main mold body includes a main bin body, a meshing groove is opened at the top of the main bin body, and a processing bin is slidably inserted into the inner wall of the meshing groove.

[0009] Optionally, the lateral limiting mechanism includes a raised ring arranged on the top of the main bin body, several inclined surfaces are arranged on the surface of the raised ring, a limiting protrusion is arranged at the bottom of the cover plate, and several meshing surfaces are respectively arranged on the surface of the limiting protrusion to fit on the surfaces of several inclined surfaces.

[0010] Optionally, slots are provided on both sides of the main bin body and the cover plate.

[0011] Optionally, notches are provided on both sides of the inner wall of the engagement groove, and pinch grooves are provided on both sides of the processing bin.

[0012] Optionally, disassembly and assembly protrusions are provided on the surface of the processing bin, and the disassembly and assembly protrusions are slidably inserted into the inner wall of the engagement groove.

[0013] Compared with the prior art, the present utility model has at least the following beneficial effects:

[0014] In the above solution, by providing a main mold body for pouring gold blocks and a cover plate is provided above the main mold body, so that during use, the user can place a plurality of metal products inside the main mold body, pick up the cover plate by the gripper and place it above the main mold body. Under the action of the lateral limiting mechanism, the cover plate is restricted above the main mold body, avoiding the problem that the cover plate shakes due to the user holding the main mold body and walking, thus affecting the processing process.

[0015] 2. In the above solution, by splitting the main mold body which is integrally formed in the prior art into a main bin body and a processing bin embedded in the inner wall of the engagement groove at the top thereof, the design of embedding the processing bin into the inner wall of the main bin body not only ensures the overall structural strength of the mold, but also facilitates the replacement and maintenance of the processing bin. At the same time, the shape of the inner wall of the processing bin can be diverse. When it is necessary to change the shape of the gold block, only the processing bin with a different inner wall shape needs to be replaced. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] As Figures 1 to 5 shown, an embodiment of the present utility model provides a graphite mold, which includes a main mold body 1, and a cover plate 2 is arranged above the main mold body 1; it further includes a lateral limiting mechanism 3, and the lateral limiting mechanism 3 is used to limit the position of the cover plate 2 above the main mold body 1 to prevent it from sliding on the horizontal plane. The main components of the main mold body 1 are: a main storage body 101, and a meshing groove 102 is opened at the top of the main storage body 101. During use, the user needs to insert a processing bin 103 for casting gold blocks into the inner wall of the meshing bin to complete the assembly of the overall structure of the main mold body 1. The main components of the lateral limiting mechanism 3 are: a raised ring 301 arranged at the top of the main storage body 101, and a limiting protrusion 303 is arranged at the bottom of the cover plate 2. During use, when the user places the cover plate 2 above the main mold body 1, the limiting protrusion 303 at the bottom of the cover plate 2 will fit against the inner wall of the raised ring 301. Since a plurality of meshing surfaces 304 are opened on the surface of the limiting protrusion 303, and a plurality of inclined surfaces 302 are opened on the surface of the raised ring 301, therefore, a plurality of meshing surfaces 304 will smoothly fit against the surfaces of a plurality of inclined surfaces 302, so that during subsequent use, the cover plate 2 will be placed more stably above the main mold body 1. Even if the main mold body 1 is tilted, due to the limiting effect of the raised ring 301 and the limiting protrusion 303, it is very difficult for the cover plate 2 to fall off.

[0031] By setting a main mold body 1 for pouring gold ingots, and a cover plate 2 is arranged above the main mold body 1. When in use, the user can place multiple metal products inside the main mold body 1. After clamping the cover plate 2 with a gripper and placing it above the main mold body 1, under the action of the lateral limiting mechanism 3, the cover plate 2 is restricted above the main mold body 1, avoiding the problem that the cover plate 2 shakes due to the user clamping the main mold body 1 and walking, thus affecting the processing process.

[0032] As Figures 1 to 5 shown, slots 4 are provided on both sides of the main bin body 101 and the cover plate 2. When in use, the user can insert the two clamping ends of the gripper into the inner wall of the slot 4 to take the main bin body 101 and the cover plate 2. Notches 5 are provided on both sides of the inner wall of the meshing groove 102, and pinch grooves 6 are provided on both sides of the processing bin 103. When it is necessary to take out the processing bin 103 from the main bin body 101, two fingers can be dug into the inner wall of the two pinch grooves 6 to take out the processing bin 103.

[0033] As Figure 2 shown, disassembly and assembly protrusions 7 are provided on the surface of the processing bin 103, and the disassembly and assembly protrusions 7 are slidably inserted into the inner wall of the meshing groove 102. When in use, the user can assist in disassembling and assembling the processing bin 103 by touching the disassembly and assembly protrusions 7 with an external object.

[0034] The working principle of the present utility model: First, after the user places the gold product inside the processing bin 103, the cover plate 2 is placed on the top of the processing bin 103, and the main bin body 101 is placed inside the heating device by a gripper for heating. After heating is completed, it is taken out, and then the demolding operation can be carried out. It should be noted that: currently, graphite powder is widely used as a mold release agent, mainly because of its excellent lubrication and high-temperature resistance characteristics. The general usage method is to evenly apply graphite powder in the mold cavity, which can form a lubricating film. This film can effectively isolate the high-temperature metal liquid from the mold, avoid adhesion, and thus ensure that the casting can be easily demolded after forming.

[0035] Secondly, when the user places the cover plate 2 on the top of the processing bin 103, several limiting protrusions 303 at the bottom of the cover plate 2 will fit on the surface of the protrusion ring 301, thereby achieving better limiting of the cover plate 2.

[0036] The present utility model covers any substitutions, modifications, equivalent methods and solutions made within the essence and scope of the present utility model. In order to enable the public to have a thorough understanding of the present utility model, specific details are described in detail in the following preferred embodiments of the present utility model. However, those skilled in the art can fully understand the present utility model without these detailed descriptions. In addition, in order to avoid unnecessary confusion to the essence of the present utility model, well-known methods, processes, procedures, components and circuits are not described in detail.

[0037] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present utility model.
