Description

Technical Field

[0001] This invention belongs to the field of casting mold technology, specifically a copper alloy casting mold that is easy to adjust in temperature. Background Technology

[0002] Traditional copper alloy casting molds suffer from several drawbacks in actual production. First, they suffer from limited temperature monitoring and a single temperature control method. Previous molds often employed an integrated temperature control structure, making it impossible to differentiate the temperature of different areas within the mold. Furthermore, the simple temperature detection methods made it difficult to capture changes in the overall temperature field and local temperature gradients. During the solidification process of the molten copper alloy, uneven cooling rates easily led to defects such as shrinkage cavities, porosity, and cracks, significantly reducing the casting yield. Second, the piping structure of existing temperature control equipment is incompatible with the mold's opening and closing movements. Interference easily occurs between the heating and cooling mechanisms and the moving parts of the mold. Moreover, the accuracy of switching between hot and cold media and flow rate regulation is insufficient, making it difficult to match the process temperature requirements of different grades of copper alloys at each stage of preheating, pouring, solidification, and demolding, resulting in poor process adaptability.

[0003] Patent application CN202411727920.3 discloses an intelligent temperature-controlled casting mold, including a support base; it also includes: a cooling mechanism fixedly installed at the center of the top surface of the support base, the cooling mechanism including a cooling frame, and the cooling frame fixedly installed at the center of the top surface of the support base; wherein, preheating mechanisms are fixedly installed on the left and right sides above the support base, and the preheating mechanisms include preheating frames, and the preheating frames are fixedly installed on the left and right sides of the top surface of the support base. In the above solution, during the merging of the upper mold body and the lower mold body, the preheating mechanism flips to heat the cavities on the upper and lower sides, avoiding excessive temperature difference with the material that would affect the service life. At the same time, the temperature control module separates the cooling circulation pipe from the lower mold body through the closed partition of the cooling mechanism, avoiding rapid cooling that could cause cracks, thus improving the casting accuracy and temperature control effect.

[0004] However, the existing casting components have a low degree of automation, and most rely on manual monitoring and manual adjustment of temperature parameters. This not only results in large operational errors, but also lacks data traceability and remote control capabilities. In addition, the lack of a precise positioning structure when the mold is closed makes it easy for mold cavity misalignment to occur, which further affects casting accuracy and production stability.

[0005] Therefore, in order to solve the above-mentioned technical problems, the present invention proposes a copper alloy casting mold that is easy to adjust in temperature. Summary of the Invention

[0007] To achieve the above objectives, the present invention provides the following technical solution: a copper alloy casting mold that facilitates temperature regulation, comprising a casting mold, wherein the casting mold includes an upper mold and a lower mold, the upper mold and the lower mold being spatially corresponding to each other, and the upper mold having a pouring gate and a vent through the end away from the lower mold; the outer periphery of the casting mold is provided with an auxiliary component for controlling the position of the casting mold; the auxiliary component is connected to a plurality of telescopic components at the end near the casting mold, and the interior of the plurality of telescopic components is hollow; the side of the telescopic component away from the casting mold is connected to an output component, and the output component can contact the casting mold; The upper mold and the lower mold are connected by a temperature-controlled copper tube. The output component can extend into the temperature-controlled copper tube, and the output component is equipped with a temperature sensor for identifying the temperature of the casting mold.

[0008] Preferably, the auxiliary component includes a base, one end of which is connected to a plurality of slide rails, and the axial direction of the plurality of slide rails is perpendicular to the plane of the base. A movable component is slidably mounted on the slide rails, and a support plate is detachably connected to the end of the slide rail away from the base. The plurality of telescopic components are evenly distributed on the base and the movable components, and the position of the base corresponds to the position of the lower mold, and the position of the movable component corresponds to the position of the upper mold.

[0009] Preferably, the upper mold is connected to a guide post at one end near the lower mold, and the lower mold has a mating hole, with the guide post corresponding to the position of the mating hole.

[0010] Preferably, the auxiliary component is distributed at both ends along its length and is connected to a heating component and a cooling component for regulating the temperature of the casting mold, respectively, and neither the heating component nor the cooling component interferes with the movement of the movable component.

[0011] Preferably, the movable component includes a movable plate that is slidably connected to the slide rail. A horizontal air guide groove is provided in the movable plate, and a communication hole for connecting with the telescopic component is provided at one end of the air guide groove near the casting mold.

[0012] Preferably, the heating assembly includes a heating section, and at least two heat-conducting pipes are connected to the heating section; The cooling assembly includes a cooling box, and at least two telescopic pipes are connected to the cooling box; At least two of the heat-conducting pipes and at least two of the telescopic pipes are respectively connected to the air guide groove at one end near the auxiliary component.

[0013] Preferably, both the heat-conducting pipe and the telescopic pipe are composed of pipes with adjustable length.

[0014] Preferably, the output component includes a filter cartridge portion, the ends of which are distributed along the length direction and connected to the telescopic component, and a sealing plate is slidably provided on the filter cartridge portion to seal the filter cartridge portion.

[0015] Preferably, the filter cartridge includes a barrel body, the barrel body has a sliding groove for sealing by the sealing plate, and a plurality of filter holes are formed through the barrel body, with an adjustment plate connected to the filter holes for regulating the outflow rate of the temperature-controlled medium.

Meanwhile, the medium flow rate can be dynamically adjusted to adapt to the casting process requirements of various copper alloys such as tin bronze and brass. Attached Figure Description

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] like Figure 1 - Figure 4As shown, this invention discloses a copper alloy casting mold that facilitates temperature regulation, including a casting mold 1. The casting mold 1 includes an upper mold 101 and a lower mold 102, which are spatially corresponding to each other. Before the copper alloy is cast, the upper mold 101 and the lower mold 102 are in a separated state, which facilitates the inspection of the mold cavity state inside the casting mold 1 and ensures that the cast workpiece meets the casting requirements. The upper mold 101 has a pouring port 1011 and a vent 1012 through it at the end away from the lower mold 102. The pouring port 1011 is used for the copper alloy liquid to enter the mold cavity, and the vent 1012 is used for the hot air generated during the cooling process of the copper alloy liquid to be discharged from the mold cavity. An auxiliary component 2 for controlling the position of the casting mold 1 is provided on the outer periphery of the casting mold 1. Multiple telescopic components 5 are connected to the end of the auxiliary component 2 near the casting mold 1. The auxiliary component 2 is connected to the casting mold 1 through the telescopic components 5. By adjusting the position of the auxiliary component 2, the telescopic components 5 are moved to control the opening and closing state of the casting mold 1.

[0023] Multiple telescopic components 5 are hollow inside. The hollow cavity inside the telescopic component 5 is used to provide a transmission path for the temperature control medium. The side of the telescopic component 5 away from the casting mold 1 is connected to an output component 6 for conducting the medium inside the telescopic component 5. The output component 6 can contact the casting mold 1. Therefore, when it is necessary to transfer the temperature of the surface of the casting mold 1, the medium required for temperature control is transmitted through the telescopic component 5 and then acts on the body of the casting mold 1 through the output component 6, so as to realize the temperature intervention of the casting mold 1.

[0024] It should be noted that multiple telescopic components 5 contact different end faces of the casting mold 1, and each output component 6 can be independently controlled, thereby achieving individual control of the temperature of different areas of the casting mold 1.

[0025] Temperature-controlled copper pipes 105 for temperature regulation medium transmission are connected to the outer periphery of the upper mold 101 and the lower mold 102. The temperature-controlled copper pipes 105 on each end face are not connected to each other. In order to ensure that the temperature-controlled copper pipes 105 can intervene in the temperature of the copper alloy in the upper mold 101 and the lower mold 102, the temperature-controlled copper pipes 105 are laid in a serpentine pattern on the surface of the upper mold 101 and the lower mold 102 when the temperature-controlled copper pipes 105 are connected to the casting mold 1.

[0026] The output component 6 can extend into the temperature control copper tube 105. The temperature control copper tube 105 has a through hole for connecting the output component 6. Under the action of the telescopic component 5, the output component 6 is driven to connect with the through hole. The output component 6 is equipped with a temperature sensor for identifying the temperature of the casting mold 1, so as to identify and sense the temperature of the area touched by the output component 6 and adjust the temperature of the copper alloy in the mold cavity in a timely manner.

[0027] It should be noted that when the output component 6 is connected to the through hole, the output component 6 can seal the edge of the through hole to prevent the temperature control medium from flowing out.

[0028] Specifically, when the temperature sensor detects that the overall temperature drop rate of the casting mold 1 is too fast during the process of identifying the temperature outside the casting mold 1, which affects the molding quality of the copper alloy liquid in the mold cavity, the temperature control copper tube 105 is filled with a heating medium to suppress the temperature dissipation of the casting mold 1, thereby slowing down the heat exchange efficiency between the copper alloy liquid and the casting mold 1.

[0029] When the temperature sensor detects that the overall temperature of the casting mold 1 is dropping slowly, the temperature control copper tube 105 is filled with cooling medium to improve the heat exchange efficiency between the copper alloy liquid and the casting mold 1.

[0030] Furthermore, when the temperature of a single end face of the casting mold 1 is abnormal, the temperature control copper pipe 105 on that end face can be individually controlled to ensure the forming quality of the copper alloy casting.

[0031] It is also important to note that the temperature sensor adopts a multi-sensor fusion array, including at least 16 high-precision temperature sensors distributed in the mold cavity, mold outer wall, temperature control copper tube 105 inlet, and temperature control copper tube 105. This enables three-dimensional monitoring of the mold temperature field. At the same time, the intelligent main control unit uses a Kalman filter algorithm to fuse multiple temperature data, eliminate measurement noise and interference, construct a real-time visualization model of the mold's three-dimensional temperature field, and accurately capture the temperature gradient and change trend of each region of the mold.

[0032] Furthermore, to ensure that the auxiliary component 2 can effectively control the casting mold 1, the auxiliary component 2 includes a base 201 for stable connection. One end of the base 201 is connected to multiple slide rails 202 for limiting the movement area, and the axial direction of the multiple slide rails 202 is perpendicular to the plane of the base 201. An active component 203 for controlling the position of the upper mold 101 is slidably mounted on the slide rails 202. By using the slide rails 202 to constrain the movement position of the active component 203, it is ensured that the upper mold 101 and the lower mold 102 can be completely corresponded in space to meet the casting requirements. A support plate 204 for maintaining the vertical angle stability of the slide rail 202 is detachably connected to the end of the slide rail 202 away from the base 201. In this solution, the number of slide rails 202 is preferably four, and they are evenly distributed on the four corners of the base 201. The support plate 204 is connected to one end of the slide rail 202 to ensure that the slide rail 202 will not tilt under the influence of gravity, thus affecting the stable sliding of the active component 203.

[0033] Specifically, multiple telescopic components 5 are evenly distributed on the base 201 and the movable component 203, with the position of the base 201 corresponding to the position of the lower mold 102 and the position of the movable component 203 corresponding to the position of the upper mold 101. The connection between the auxiliary component 2 and the casting mold 1 is achieved through the telescopic components 5, thereby maintaining the upper mold 101 and the lower mold 102 at the connection position between the base 201 and the movable component 203, ensuring the stability of the copper alloy during casting.

[0034] Furthermore, to ensure that the mold cavity does not misalign when the upper mold 101 and the lower mold 102 are in contact with each other, a guide post 104 is connected to one end of the upper mold 101 near the lower mold 102. The lower mold 102 has a mating hole 103. The guide post 104 is positioned corresponding to the mating hole 103, and the guide post 104 can be inserted into the mating hole 103. During casting, the upper mold 101 is moved by the movable component 203, causing the upper mold 101 to contact the lower mold 102. Before the upper mold 101 and the lower mold 102 are fully in contact, the guide post 104 is inserted into the mating hole 103 to ensure that the mold cavity in the casting mold 1 meets the casting requirements.

[0035] Furthermore, in order to ensure that the temperature inside the casting mold 1 can be regulated, the two ends of the auxiliary component 2 distributed along the length direction are respectively connected to a heating component 3 and a cooling component 4 for regulating the temperature of the casting mold 1. Neither the heating component 3 nor the cooling component 4 will interfere with the movement of the movable component 203. The heating medium of the heating component 3 is hot air or other flowing medium that can provide a heat source, and the cooling medium of the cooling component 4 is preferably cold water or other flowing medium that can provide heat exchange.

[0036] Furthermore, the auxiliary component 2 is also connected to an intelligent main control unit, which has a built-in PID closed-loop control algorithm and a copper alloy casting temperature curve database. It can automatically adjust the flow rate, velocity and switching timing of the heating and cooling media according to real-time temperature data to achieve independent and precise temperature control in multiple areas. The intelligent main control unit is electrically connected to the temperature sensor, heating component 3, cooling component 4 and the telescopic component 5 respectively.

[0037] Furthermore, such as Figure 5 As shown, to ensure that the temperature control medium can be applied from the heating component 3 and the cooling component 4 to the casting mold 1, and since the base 201 and the movable component 203 have the same internal structure, to avoid repetition, only the structure of the movable component 203 will be described here. The movable component 203 includes a movable plate 2031 for support and connection. The movable plate 2031 is slidably connected to the slide rail 202. A horizontal air guide groove 2032 is provided in the movable plate 2031, that is, the air guide groove 2032 is continuous and runs through the frame shape of the movable plate 2031, which promotes the circulation and conduction of the temperature control medium in the air guide groove 2032. A connecting hole 2033 is provided at the end of the air guide groove 2032 near the casting mold 1 for connecting with the telescopic component 5, so that the temperature control medium in the air guide groove 2032 is transmitted to the telescopic component 5 through the connecting hole 2033, and then the temperature control medium in the telescopic component 5 is applied to the casting mold 1 through the output component 6.

[0038] Furthermore, the heating assembly 3 includes a heating section 301 for storing and generating a heating medium. The heating section 301 is connected to at least two heat-conducting pipes 302 for transmitting the heat source medium. The at least two heat-conducting pipes 302 are respectively connected to the movable assembly 203 and the air guide groove 2032 in the base 201.

[0039] The cooling assembly 4 includes a cooling box 402 for storing and manufacturing a cooling medium. At least two telescopic pipes 401 for transmitting the cooling medium are connected to the cooling box 402. The at least two telescopic pipes 401 are respectively connected to the movable assembly 203 and the air guide groove 2032 in the base 201.

[0040] Specifically, the heating unit 301 uses a PTC ceramic heating element and the heating medium is heat transfer oil or compressed hot air. The cooling box 402 uses a water-cooled refrigeration unit and the cooling medium is deionized water or ethylene glycol aqueous solution.

[0041] Meanwhile, both the heating component 3 and the cooling component 4 are equipped with electronic proportional control valves and flow sensors. The intelligent main control unit precisely controls the flow rate of the medium through analog signals, thereby controlling the flow rate adjustment range and adjustment accuracy.

[0042] It should be noted that, according to the detection data of the temperature sensor, each air guide groove 2032 contains only a single temperature regulating medium. At the same time, according to the actual processing requirements, the air guide grooves 2032 in the base 201 and the movable component 203 can be distributed with temperature regulating media of different properties. If necessary, the temperature regulating media can be mixed in the air guide grooves 2032 at the same time, and the temperature regulating media can be dynamically adjusted according to the cooling state in the casting mold 1.

[0043] Furthermore, both the heat-conducting pipe 302 and the telescopic pipe 401 are made of pipes with adjustable length, so that when the movable component 203 drives the upper mold 101 to move, the heat-conducting pipe 302 and the telescopic pipe 401 can extend or shorten as the movable component 203 moves.

[0044] Furthermore, such as Figure 6 - Figure 9 As shown, in order to ensure that the temperature control medium can be discharged from the telescopic component 5 and that each output component 6 can be controlled individually, the output component 6 includes a filter cartridge 601. The ends of the filter cartridge 601 distributed along the length direction are connected to the telescopic component 5, thereby ensuring the communication between the telescopic component 5 and the filter cartridge 601 and ensuring that the medium inside the telescopic component 5 can enter the filter cartridge 601. A sealing plate 602 is slidably provided on the filter cartridge 601 to block the filter cartridge 601. The sealing plate 602 is used to seal the through hole on the filter cartridge 601, thereby preventing the temperature control medium inside the filter cartridge 601 from being introduced into the temperature control copper tube 105, and realizing the control of the output state of the output component 6.

[0045] Furthermore, the filter cartridge 601 includes a barrel body 6011 for connection. The barrel body 6011 has a sliding groove 6012 for sealing the sealing plate 602, allowing the sealing plate 602 to slide into the sliding groove 6012. The barrel body 6011 has multiple filter holes for discharging the temperature-controlled medium. An adjusting plate 6013 for regulating the outflow rate of the temperature-controlled medium is connected to the filter holes. The adjusting plate 6013 is composed of multiple arc-shaped plates, which are rotatably connected to the filter hole wall. An elastic membrane is connected between two adjacent arc-shaped plates. Based on the detection data of the temperature sensor, the tilt angle of the adjusting plate 6013 is adjusted to regulate the aperture of the filter holes, so that the flow rate and flow of the temperature-controlled medium meet the temperature regulation requirements of the casting mold 1.

[0046] The intelligent main control unit is also connected to a 5G IoT communication module and a human-machine interface touch screen. The 5G IoT communication module supports remote monitoring, data uploading to the cloud, and abnormal warning SMS push functions. The human-machine interface touch screen can display the temperature curves of each area in real time, manually adjust the temperature control parameters, and select preset casting process schemes. The intelligent main control unit can record the temperature curve data and casting quality feedback of each casting process, and continuously optimize the PID control parameters through machine learning algorithms to adapt to the casting process requirements of different grades of copper alloys.

[0047] Specifically, the intelligent main control unit has a built-in database of copper alloy casting experts, which stores the optimal casting temperature curves for different grades of copper alloys such as tin bronze, aluminum bronze, brass, and cupronickel. It covers key process parameters such as preheating temperature, pouring temperature, cooling rate during solidification, and demolding temperature. Users can call up the corresponding process scheme with one click according to the casting material grade, or they can customize, edit, and store new temperature curves.

[0048] After the equipment is powered on, the intelligent main control unit first performs a system self-test, checking the working status of all temperature sensors, heating components 3, cooling components 4, and actuators. After the self-test passes, the operator selects the copper alloy grade and casting number through the human-machine interface touchscreen. The system automatically retrieves the corresponding standard temperature curves from the expert database, including: preheating stage, pouring preparation stage, solidification stage, and demolding stage. The operator can also manually modify the temperature parameters according to the actual situation.

[0049] The intelligent main control unit activates the heating component 3, causing the heat transfer medium to heat up to the set temperature. At the same time, all the closed plates 602 of the output components 6 are fully opened, and the adjustment plate 6013 is opened to the maximum degree. The 16 temperature sensors distributed in various areas of the mold collect temperature data in real time, which is then processed by Kalman filtering and transmitted to the main control unit. The main control unit uses a PID algorithm to calculate the temperature deviation and dynamically adjusts the heating power and the flow rate of the heat transfer medium.

[0050] When the temperature in a certain area reaches 90% of the set value, the opening of the regulating plate 6013 of the output component 6 in that area is automatically reduced to decrease the medium flow rate and prevent temperature overshoot. After all areas reach the preheating temperature, the system automatically enters the heat preservation mode, accurately maintaining the temperature within ±0.5℃, and begins a 30-minute countdown.

[0051] After the heat preservation process is complete, the system indicates that pouring is ready. Once the molten copper alloy is injected into the mold cavity through pouring port 1011, the temperature sensor immediately detects a temperature surge, and the intelligent main control unit automatically switches to solidification control mode. At this time, the system implements differentiated control strategies for the different states of the eight temperature control zones.

[0052] For example, in thick, hot areas of castings (such as flanges and reinforcing ribs): control the cooling rate and appropriately delay cooling to achieve sequential solidification, facilitate molten metal feeding, and eliminate shrinkage cavities and porosity; in thin-walled areas of castings: control the cooling rate to accelerate cooling speed, refine grain structure, and improve mechanical properties; in gating and riser areas: maintain a relatively high temperature of 150~180℃ to ensure unobstructed feeding channels.

[0053] The intelligent main control unit performs temperature sampling and PID calculation 10 times per second. By independently controlling the opening of the adjustment plate 6013 of each output component 6, it precisely controls the medium flow rate in each temperature control copper pipe 105 to achieve the target cooling rate in different areas.

[0054] When the temperature drops too quickly, the heating medium is automatically switched in; when the temperature drops too slowly, the cooling medium flow rate is automatically increased. Throughout the solidification process, the system plots the temperature curve in real time and compares the deviation with the standard curve. An alarm is automatically triggered when the deviation exceeds ±2℃.

[0055] Once the temperature in all zones drops to 80℃ and the temperature change rate is less than 0.1℃ / min for a certain period of time, the intelligent main control unit determines that the casting has fully solidified, automatically stops the temperature control system, and prompts that the mold can be opened and the casting removed. Simultaneously, the complete temperature curve, process parameters, and control logs of the casting process are automatically stored in local and cloud databases, including timestamps, temperature data for each zone, heating and cooling action records, alarm information, etc., facilitating quality traceability and process analysis.

[0056] Meanwhile, managers can utilize the 5G IoT remote monitoring function to remotely view the real-time operating status of all online casting equipment through a PC management platform or mobile APP, including the current temperature curve, process progress, equipment status, and alarm information. It supports remote modification of process parameters, pausing / resuming production, and remote firmware upgrades. When the equipment detects abnormal temperature, sensor failure, or abnormal pressure, the system automatically sends alarm SMS messages and APP push notifications to multiple preset manager mobile phone numbers via the 5G network to ensure that faults can be handled in a timely manner and avoid the generation of batch scrap.
