Description

Technical Field

[0001] This utility model belongs to the technical field of mold processing and casting equipment, specifically a device for processing and casting valve molds. Background Technology

[0002] In modern industrial manufacturing, the processing and casting of valve molds are crucial steps in producing high-quality valve products. The precision of the valve mold and the quality of casting directly affect the performance and service life of the final product. Currently, valve mold processing and casting typically rely on traditional manual operations or semi-automated equipment. While these methods can meet certain production needs, they still have many shortcomings in practical applications. For example, traditional casting equipment is prone to defects such as air bubbles and inclusions during mold filling, leading to uneven internal structure of the casting and affecting the mechanical properties of the product. Furthermore, existing equipment has limited temperature control and flow rate adjustment capabilities during the casting process, making it difficult to achieve precise filling of complex molds, thus reducing production efficiency and yield. At the same time, existing casting equipment also has significant shortcomings in terms of ease of operation and automation, increasing the need for manual intervention and the risk of operational errors. Therefore, developing a valve mold processing and casting device that can improve casting precision, optimize mold filling effects, and enhance automation levels has become an urgent technical challenge. Utility Model Content

[0003] This utility model relates to the technical field of valve mold processing, specifically a casting device for valve mold processing. Currently, some casting devices suffer from poor fluidity, air bubble formation, and uneven cooling during molten metal injection, leading to unstable finished product quality. Furthermore, some devices employ complex multi-channel designs, resulting in cumbersome operation and high maintenance costs. This utility model provides the following technical solution: a casting device for valve mold processing, comprising: a casting cavity with a casting channel inside; a flow guiding component, including a flow guide plate located within the casting channel and an adjusting rod fixedly connected to the flow guide plate, the adjusting rod being horizontally slidably connected to the casting cavity; a first elastic element, whose elastic deformation recovery process drives the flow guide plate to move towards the center of the casting channel to optimize the molten metal flow path; and a temperature control component, including a heating sleeve fixedly connected to the casting cavity and a vertically slidably connected to the heating sleeve. The heating sleeve contains an internal heat insulation plate and an adjusting ring threaded onto the heating sleeve. The adjusting ring is rotatably connected to the heat insulation plate. The heating sleeve has a connected constant temperature zone and a gradually cooling zone. Multiple heat-conducting fins arranged in a ring array are fixedly connected to the heat insulation plate. As the adjusting ring rotates relative to the heating sleeve thread, it pushes the heat insulation plate downward so that each heat-conducting fin abuts against the inner wall of the constant temperature zone, causing the ends of each heat-conducting fin to close together to form a uniform heat dissipation channel. Then, the heat insulation plate moves downward in the gradually cooling zone to drive the flow guiding component to adjust the cooling rate of the molten metal.

[0004] Preferably, it further includes a locking assembly comprising: a locking block that is horizontally slidably connected to the casting cavity; and a second elastic element whose process of restoring elastic deformation is used to drive the locking block to slide horizontally to engage with the adjusting rod.

[0005] Preferably, each of the heat-conducting sheets has an arc-shaped groove fixedly connected to the side that abuts against the constant temperature zone, and a heat-conducting silicone strip is embedded in the groove.

[0006] Preferably, the adjusting ring includes an external thread section that mates with the heating sleeve thread and a rotary handle that is fixedly connected to the external thread section, and the rotary handle is provided with anti-slip texture.

[0007] Preferably, a baffle plate is fixedly connected to one side of the casting cavity. When the flow guiding assembly adjusts the flow path of the molten metal, a closed flow guiding area is formed between the baffle plate, the casting cavity, and the flow guiding plate to prevent the molten metal from overflowing the casting channel.

[0008] Preferably, the first elastic element is a compression spring, which is located inside the cavity of the adjusting rod. One end of the compression spring is fixedly connected to the guide plate, and the other end is fixedly connected to the bottom end of the cavity.

[0009] Preferably, the bottom of the locking block is fixedly connected to a wedge-shaped protrusion, and the inclined surface of the wedge-shaped protrusion is arranged downwards.

[0010] In summary, this device not only dynamically adjusts the flow path of the guide plate according to the molten metal flow rate, effectively preventing air bubbles or blockages during casting and improving the overall practicality of the device, but also, because the adjusting ring and heating sleeve are connected by threads, the rotation of the adjusting ring's threads ensures uniform heat dissipation between the casting cavity and the molten metal, allowing for stable cooling and molding. This increases the controllability of the cooling process, preventing defects caused by excessively fast or slow cooling and improving the overall processing accuracy. Furthermore, the operation reduces the number of thread turns between the adjusting ring and heating sleeve, simplifying operation and significantly reducing the workload of operators.

[0015] This utility model provides a valve mold processing and casting device, the specific implementation of which is described in conjunction with the appendix. Figure 1 To be continued Figure 3 Please provide a detailed explanation. For example... Figure 1 As shown, the casting device includes a casting cavity 1, which has a casting channel 2 for the injection and flow of molten metal. A flow guiding assembly is installed within the casting channel 2 and mainly includes a guide plate 3, an adjusting rod 4, and a first elastic element 5. The guide plate 3 is horizontally slidably connected to the casting cavity 1 via the adjusting rod 4. The first elastic element 5 is a compression spring 19, one end of which is fixedly connected to the guide plate 3, and the other end is fixedly connected to the bottom of the inner cavity of the adjusting rod 4. When molten metal is injected, the restoring elastic deformation of the first elastic element 5 drives the guide plate 3 to move towards the center of the casting channel 2, thereby dynamically adjusting the flow path of the molten metal, optimizing fluidity, and preventing bubble formation.

[0016] The temperature control component is one of the core parts of this utility model, and its structure is as follows: Figure 2 and Figure 3 As shown. The temperature control assembly includes a heating sleeve 6, a heat insulation plate 7, an adjusting ring 8, and multiple heat-conducting plates 11. The heating sleeve 6 is fixedly connected to the casting cavity 1, and its interior has a constant temperature zone 9 and a gradual cooling zone 10. The heat insulation plate 7 is vertically slidably connected inside the heating sleeve 6 and is rotatably connected to the adjusting ring 8 by a threaded connection. The adjusting ring 8 includes an external thread section 16 and a rotating handle 17. The external thread section 16 is threadedly engaged with the heating sleeve 6, and the rotating handle 17 has anti-slip textures for easy operation. Multiple heat-conducting plates 11 are fixedly connected to the heat insulation plate 7 in a ring array. These heat-conducting plates 11 have heat-conducting silicone strips 15 embedded in the constant temperature zone 9 through arc-shaped grooves 14 to enhance the heat conduction effect. When the adjusting ring 8 rotates relative to the heating sleeve 6, it pushes the heat insulation plate 7 downward, causing each heat-conducting plate 11 to abut against the inner wall of the constant temperature zone 9, and the ends of the heat-conducting plates 11 close together to form a uniform heat dissipation channel. Subsequently, the heat insulation plate 7 continues to move downward within the gradually cooling zone 10, driving the flow guiding component to further adjust the cooling rate of the molten metal, ensuring that the molten metal can be stably cooled and formed.

[0017] The specific structure of the locking component is as follows: Figure 3As shown, it includes a locking block 12 and a second elastic element 13. The locking block 12 is horizontally slidably connected to the casting cavity 1. The restoring elastic deformation process of the second elastic element 13 drives the locking block 12 to slide horizontally, making it engage with the adjusting rod 4. A wedge-shaped protrusion 20 is fixedly connected to the bottom of the locking block 12. The inclined surface of the wedge-shaped protrusion 20 is arranged downwards to facilitate quick positioning and stable engagement during the locking process. The function of the locking assembly is to fix the position of the adjusting rod 4 and prevent the position of the guide plate 3 from shifting due to external vibration or molten metal impact during the casting process, thereby ensuring the stability of the casting process.

[0018] The baffle plate 18 is fixedly connected to one side of the casting cavity 1. Its function is to form a closed flow guiding area together with the casting cavity 1 and the baffle plate 3 when the flow guiding assembly adjusts the flow path of the molten metal, preventing the molten metal from overflowing the casting channel 2. The design of the baffle plate 18 not only improves the safety of the device, but also further optimizes the flow path of the molten metal and reduces waste during the casting process.

[0019] In practical applications, the working principle of this invention is as follows: First, molten metal is injected into the casting channel 2 of the casting cavity 1, and the flow path of the molten metal is dynamically adjusted by the guide plate 3. The restoring elastic deformation process of the first elastic element 5, i.e., the compression spring 19, drives the guide plate 3 to move towards the center of the casting channel 2, thereby optimizing the flow path of the molten metal and preventing the generation of air bubbles and blockage. At the same time, the operator rotates the rotating handle 17 of the adjusting ring 8, causing the adjusting ring 8 to rotate relative to the heating sleeve 6. During this process, the adjusting ring 8 pushes the heat insulation plate 7 downward, and the heat-conducting sheet 11 on the heat insulation plate 7 enters the constant temperature zone 9, and makes close contact with the inner wall of the constant temperature zone 9 through the heat-conducting silicone strip 15, forming a uniform heat dissipation channel. As the heat insulation plate 7 continues to move downward to the gradual cooling zone 10, the ends of the heat-conducting sheet 11 gradually close, further adjusting the cooling rate of the molten metal. In this way, the molten metal can maintain a stable temperature in the constant temperature zone 9, and then gradually cool and solidify in the gradual cooling zone 10, avoiding defects in the finished product caused by excessively fast or slow cooling.

[0020] Throughout the casting process, the locking assembly plays a crucial auxiliary role. Once the position of the adjusting rod 4 is adjusted, the second elastic element 13 drives the locking block 12 to slide horizontally, engaging it with the adjusting rod 4. The wedge-shaped protrusion 20 at the bottom of the locking block 12 achieves rapid positioning through its inclined surface design, ensuring the position of the adjusting rod 4 remains fixed. Furthermore, the enclosed flow guiding area formed by the baffle plate 18, the casting cavity 1, and the guide plate 3 effectively prevents molten metal from overflowing, further improving the practicality and safety of the device.

[0021] In summary, this invention achieves precise control of the flow path and cooling rate of molten metal through the synergistic effect of the flow guiding component and the temperature control component. The flow guiding plate 3 dynamically adjusts the flow path according to the molten metal flow rate, effectively preventing the occurrence of bubbles and blockages. The temperature control component, through the screw rotation of the adjusting ring 8, achieves uniform heat dissipation and stable cooling and molding of the molten metal in the constant temperature zone 9 and the gradual cooling zone 10. The locking component and the baffle plate 18 further enhance the stability and safety of the device. The entire device is simple to operate, has low maintenance costs, and significantly improves the finished product quality and production efficiency of valve mold processing.

Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
