Description

Technical Field

[0001] This utility model relates to the field of metal rod casting, and in particular to a mold for metal rod casting. Background Technology

[0002] Metal bar casting is a process in which molten metal is injected into a specialized mold using a specific method, and after cooling and solidification, it forms a rod-shaped metal billet with a predetermined diameter and length. In this process, the mold is the core carrier. The molten metal is shaped according to the cavity within the mold. The mold must withstand the impact and heat of the high-temperature molten metal, and promote rapid solidification of the metal through its own heat dissipation or a combined cooling mechanism. Simultaneously, a feeding structure is used to reduce defects such as shrinkage cavities, ultimately resulting in a metal rod that meets dimensional and performance requirements. This is a crucial step in the production of metal bars to achieve material forming.

[0003] However, the current molds for casting metal bars have the following defects: First, the flow rate of the molten metal is unstable, which can easily lead to molding problems due to improper flow rate; second, the molds are not stable enough, and they are prone to shaking or even tipping over during casting, and it is difficult to adapt to molds of different heights, which affects the casting quality and safety.

[0004] In response to this technical problem, this application proposes a mold for casting metal rods. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a mold for casting metal rods. This mold uses a funnel to guide the flow, reducing the flow rate of the molten metal. Simultaneously, the funnel provides feeding and allows for adjustment of the funnel's height to accommodate different flow rate requirements. Clamping rings are used to hold and fix the mold, providing additional support, improving stability during casting, and supporting molds of different heights.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A mold for casting metal rods includes an iron plate, a graphite pad fixedly connected to the top side of the iron plate, a graphite mold disposed on the top side of the graphite pad, an iron ring fitted on the outer wall of the graphite mold, screws fixedly connected to the four corners of the top side of the graphite pad, locking nuts disposed on the outer wall of the screws, support grooves fixedly connected to the left and right sides of the top side of the iron plate, funnels connected to the inside of the two support grooves through an adjusting component, the height of the funnels being adjusted by the adjusting component, and support components disposed on adjacent sides of the two support grooves to provide additional support for the graphite mold.

[0007] Furthermore, the adjusting assembly includes a support rod slidably connected inside the support groove, the top end of which is fixedly connected to the bottom side of the funnel.

[0008] Furthermore, a ring is rotatably connected to the bottom end of the outer wall of the support rod, the ring is sleeved inside the support groove, and a positioning rod is fixedly connected to the outer wall of the ring.

[0009] Furthermore, the end of the positioning rod is connected to a limit rod via a torsion spring, and the outer wall of the support groove is provided with multiple positioning grooves, with the positioning rod engaging inside the positioning groove.

[0010] Furthermore, the support assembly includes a sliding groove formed on one side of the two support slots, a sliding rod slidably connected inside the sliding groove, a clamping ring fixedly connected to the end of the sliding rod, and one side of the clamping ring abutting against the outer wall of the graphite mold.

[0011] Furthermore, a threaded rod is rotatably connected inside the slide groove, and the slide rod is threaded onto the outer wall of the threaded rod.

[0012] Furthermore, a knob is rotatably connected to the top of the support groove via a damping shaft, and the top of the threaded rod is fixedly connected inside the knob.

[0013] This utility model has the following beneficial effects: In this invention, the limiting rod is rotated to a position aligned with the positioning rod to release the limiting of the positioning rod. Then, the ring is rotated to disengage the positioning rod from the positioning groove, allowing it to slide in the support groove. Subsequently, the sliding positioning rod drives the support rod to move up and down, thereby adjusting the height of the funnel to adapt to different flow rate requirements.

[0014] In this invention, a clamping ring is used to hold and fix the graphite mold, thereby providing additional support for the graphite mold and improving the stability during casting. By rotating the knob, the threaded rod is rotated, which drives the slide rod to slide up and down, thus adapting to graphite molds of different heights. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figures 1-3This utility model provides an embodiment of a metal rod casting mold, including an iron plate 1, a graphite pad 2 fixedly connected to the top side of the iron plate 1, and a graphite mold 7 set on the top side of the graphite pad 2. The iron plate 1 is used to cool down the bottom metal, which accelerates the cooling speed and achieves solidification layer by layer to reduce internal defects in the metal. It also supports the mold if it is too high, preventing the mold from tipping over during casting. An iron ring 5 is fitted on the outer wall of the graphite mold 7. A screw 4 is fixedly connected to each of the four corners of the top side of the graphite pad 2. The screw 4 is a 4-M10 screw. A locking nut 3 is set on the outer wall of the screw 4. The iron ring 5 supports the graphite mold 7, and the locking nut 3 fixes the iron ring 5. The height of the iron ring 5 can be adjusted by rotating the locking nut 3, and the iron ring 5 can be disassembled. Support grooves 6 are fixedly connected to both the left and right sides of the top side of the iron plate 1. Funnels 9 are connected inside the two support grooves 6. The flow is guided by the funnels 9 to reduce the flow rate of the molten metal. At the same time, the funnels 9 are used for filling and shrinking. The molten metal has deep shrinkage cavities during the cooling process, so excess metal can be used to fill and shrink. A valve is set at the discharge port at the bottom of the funnel 9 to control the discharge. A support rod 8 is slidably connected inside the support groove 6. The top end of the support rod 8 is fixedly connected to the bottom side of the funnel 9. A ring 14 is rotatably connected to the bottom end of the outer wall of the support rod 8. The ring 14 is fitted inside the support groove 6. A positioning rod 15 is fixedly connected to the outer wall of the ring 14. The end of the positioning rod 15 is connected to a limit rod 16 via a torsion spring. The outer wall of the support groove 6 has multiple positioning grooves. The positioning rod 15 is engaged inside the positioning groove. By moving the limit rod 16 to rotate it to a position where it is aligned with the positioning rod 15, the limitation on the positioning rod 15 is released. Then, the ring 14 is rotated to disengage the positioning rod 15 from the positioning groove, allowing it to slide in the support groove 6. Afterward, the sliding positioning rod 15 drives the support... The support rod 8 moves up and down to adjust the height of the funnel 9, thus adapting to different flow rate requirements. The principle of adjusting the height of the funnel 9 to adapt to different flow rate requirements is mainly based on the relationship between the potential energy difference of liquid flow and the channel resistance: when the height of the funnel 9 increases, the distance between its lower end and the mold pouring port increases, and the molten metal will experience a longer free fall distance after flowing out of the funnel 9. During the fall, the air resistance increases, and the efficiency of converting potential energy into kinetic energy decreases, ultimately slowing down the flow rate into the mold. Conversely, when the height of the funnel 9 decreases, the distance the liquid falls is shortened, the influence of air resistance is weakened, potential energy is more easily converted into kinetic energy, and the relative resistance of the outflow channel decreases, thereby increasing the flow rate of the molten metal. By changing the relative height of the funnel 9 and the pouring port, the initial velocity of the molten metal entering the mold can be directly adjusted, thus adapting to rare earth metal liquids with different fluidities and avoiding defects such as splashing and air entrapment caused by excessively high flow rates, or discontinuous pouring and cold shuts caused by excessively low flow rates.

[0019] Reference Figures 1-3Each of the two support grooves 6 has a sliding groove on one side of its proximity. A sliding rod 11 is slidably connected inside the sliding groove. A clamping ring 10 is fixedly connected to the end of the sliding rod 11. One side of the clamping ring 10 abuts against the outer wall of the graphite mold 7. A threaded rod 12 is rotatably connected inside the sliding groove. The sliding rod 11 is threadedly connected to the outer wall of the threaded rod 12. A knob 13 is rotatably connected to the top of the support groove 6 through a damping shaft. The top of the threaded rod 12 is fixedly connected inside the knob 13. The clamping ring 10 is used to clamp and fix the graphite mold 7, thereby providing additional support for the graphite mold 7 and improving the stability during casting. By rotating the knob 13, the threaded rod 12 is rotated, causing the threaded rod 12 to drive the sliding rod 11 to slide up and down, thereby adapting to graphite molds 7 of different heights. The damping shaft in this application adopts a type with greater resistance to prevent vibration during the use of the device from causing movement of the corresponding structure.

[0020] Working principle: First, adjust the height of the clamping ring 10 according to the height of the graphite mold 7. When the height of the clamping ring 10 needs to be adjusted, turn the knob 13 to rotate the threaded rod 12, causing the threaded rod 12 to drive the slide rod 11 to slide up and down, so that the clamping ring 10 clamps the graphite mold 7 at the corresponding height, thereby supporting the graphite mold 7. Then, put the iron ring 5 on the graphite mold 7 and make its height higher than the clamping ring 10. Then, fix the iron ring 5 to the screw rod 4 by tightening the locking nut 3. Next, adjust the height of the funnel 9. When the height of the funnel 9 needs to be adjusted, turn the limit rod 16 to rotate it to a position that is in a straight line with the positioning rod 15, thereby releasing the positioning rod 15. The positioning rod 15 is then moved out of the positioning groove by rotating the ring 14, allowing it to slide in the support groove 6. The support rod 8 is then moved up and down by sliding the positioning rod 15, thus adjusting the height of the funnel 9. After the height is adjusted, the positioning rod 15 is rotated into the positioning groove, and then the limiting rod 16 is rotated to one side of the positioning rod 15, thus blocking the positioning rod 15 in the positioning groove and preventing it from dislodging. The molten metal is then poured into the funnel 9, which guides the flow and reduces the flow rate of the molten metal. The funnel 9 also provides feeding, thus facilitating the pouring process. After pouring is complete, the poured metal rod can be removed.

[0021] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
