[0002] Traditional mold heating methods, such as inserting electric heating tubes through punching holes, or forming hot runners for heat transfer oil for heating, have certain effects, but have obvious shortcomings. These methods often result in uneven heating of the mold and insufficient heat transfer area, making it difficult to evenly increase the mold temperature to the required process temperature. Although increasing the number of electric heating tubes can increase the mold temperature, the temperature difference between different parts of the mold is large, which can easily cause thermal deformation and seriously reduce the mold rigidity, thereby affecting the manufacturing accuracy of the product and the service life of the mold. Therefore, when manufacturing large integrated parts, the pass rate of die-casting molds or extrusion casting molds manufactured by traditional methods is often low, and the above-mentioned defects often exist.

DETAILED DESCRIPTION

[0076] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0077] It should be noted that the terms "first", "second", "third", "fourth", etc. in the specification and claims of the present invention are used to distinguish different objects rather than to describe a specific order. The terms "including" and "having" in the embodiments of the present invention and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device including a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0078] Traditional mold heating methods, such as inserting electric heating tubes through punching holes, or forming hot runners for heat transfer oil for heating, have certain effects, but have obvious shortcomings. These methods often lead to uneven heating of the mold and insufficient heat transfer area, making it difficult to evenly increase the mold temperature to the required process temperature. Although increasing the number of electric heating tubes can increase the mold temperature, the temperature difference between different parts of the mold is large, which can easily cause thermal deformation and seriously reduce the mold rigidity, thereby affecting the manufacturing accuracy of the product and the service life of the mold. Therefore, the pass rate of die-casting molds or extrusion casting molds manufactured by traditional methods is often low when manufacturing large integrated parts, and the above-mentioned defects often exist. Based on this, the embodiment of the present invention discloses a heating control method, system, electronic device and storage medium for a semi-solid forming device, which can achieve precise control of the heating process by obtaining the temperature control stage of the current semi-solid forming device and determining the corresponding preset heating curve according to the stage. This control method can ensure that the device is carried out according to a predetermined temperature trajectory during the heating process, thereby meeting the temperature accuracy requirements of the semi-solid forming process.

[0079] Embodiment 1

[0080] See also Figure 1 , Figure 1 It is a flow chart of the heating control method of the semi-solid forming device disclosed in the embodiment of the present invention. Among them, the execution subject of the method described in the embodiment of the present invention is an execution subject composed of software and / or hardware, and the execution subject can receive relevant information by wired or / and wireless means, and can send certain instructions. Of course, it can also have certain processing functions and storage functions. The execution subject can control multiple devices, such as a remote physical server or cloud server and related software, or it can be a local host or server and related software that performs related operations on a device placed somewhere. In some scenarios, multiple storage devices can also be controlled, and the storage devices can be placed in the same place or different places as the devices. For example Figure 1 As shown, the heating control method based on the semi-solid forming device includes the following steps:

[0081] S101: Obtaining the temperature control stage of the current semi-solid forming device;

[0082] S102: determining a corresponding preset heating curve according to the temperature control stage, and controlling the working states of the oil heating component and the electric heating component in the heating component according to the preset heating curve;

[0083] S103: acquiring real-time temperature information detected by the thermal sensor during the heating process, and determining a corresponding real-time temperature curve according to the real-time temperature information;

[0084] S104: performing data matching on the real-time temperature curve and the target heating curve, and adjusting the working states of the oil heating component and the electric heating component in the heating component according to the matching result.

[0085] The above scheme has the following technical effects when implemented: First, accurate temperature control: By obtaining the temperature control stage of the current semi-solid forming device and determining the corresponding preset heating curve according to the stage, accurate control of the heating process can be achieved. This control method can ensure that the device follows the predetermined temperature trajectory during the heating process, thereby meeting the temperature accuracy requirements of the semi-solid forming process. Second, real-time temperature monitoring and adjustment: The temperature information during the heating process is detected in real time by the thermal sensor, and the corresponding real-time temperature curve is generated, so that the temperature change during the heating process can be monitored in real time. The real-time temperature curve is matched with the target heating curve, and the temperature deviation can be found in time, and the working state of the heating component (including the oil heating component and the electric heating component) can be adjusted in real time according to the matching result. This adjustment can ensure that the heating process is always kept within the predetermined temperature range, improving the molding quality and process stability. Third, flexible combination of heating methods: This technical effect is also reflected in the ability to flexibly adjust the working state of the oil heating component and the electric heating component according to the temperature control stage and real-time temperature information. This combined heating method can make full use of the advantages of different heating methods, such as the uniformity of oil heating and the rapid responsiveness of electric heating, so as to achieve more efficient and stable heating control. Fourth, improve production efficiency and product quality: through precise temperature control and real-time temperature monitoring and adjustment, the heating time can be shortened, energy consumption can be reduced, and the molding quality and consistency of the product can be improved. This is very important for semi-solid molding process, because temperature is one of the key factors affecting molding quality and product performance.

[0086] Since oil heating and electric heating have different heating characteristics, the two different heating methods can be combined for heating treatment during specific implementation. Electric heating can reach higher temperatures, but there is a defect of unstable temperature control. Although oil heating cannot reach very high temperatures, the highest temperature can reach 350 degrees Celsius; however, during the temperature control process, its temperature fluctuation is small, and it can have better temperature control properties; since the semi-solid forming process has high temperature requirements, if the temperature control is not accurate, the final forming effect will be poor, so in the embodiment of the present invention, the heating characteristics of each stage are decomposed to match the corresponding heating curve for precise heating and real-time regulation.

[0087] More preferably, the temperature control stage includes a preheating stage, an extrusion molding heating stage, and a cooling and solidification stage; the corresponding preset heating curve is determined according to the temperature control stage, and the working state of the oil heating component and the electric heating component in the heating component is controlled according to the preset heating curve, including:

[0088] S1021: determining a first heating curve according to the preheating stage, and controlling the oil heating component and the electric heating component to be in an on state according to the first heating curve to heat the corresponding mold core component so that the temperature in the mold cavity reaches the set requirement;

[0089] S1022: determining a second heating curve according to the extrusion molding heating stage, and controlling the working state of each heating element in the oil heating component and the electric heating component according to the second heating curve to perform a constant temperature treatment on the corresponding mold core component to ensure that the temperature in the mold cavity is maintained within a set range;

[0090] S1023: Determine a third heating curve according to the cooling and solidification stage, and control the working state of each heating element in the oil heating component and the electric heating component according to the third heating curve to cool the corresponding mold core component to ensure that the temperature in the cavity is cooled according to the set gradient.

[0091] The solution of the embodiment of the present invention controls the working state of the oil heating component and the electric heating component through a preset heating curve (first heating curve, second heating curve, third heating curve), so as to realize precise temperature control of the mold core component. This helps to ensure that each stage of the extrusion molding process (preheating, extrusion molding heating, cooling and solidification) can be carried out within the set temperature range, thereby improving product quality and process stability. It adjusts the working state of the heating component according to different temperature control stages, so as to realize efficient use of energy. For example, in the preheating stage, both the oil heating component and the electric heating component are in the on state to quickly reach the set temperature; while in the constant temperature or cooling stage, only some of the heating components may be required to work, thereby saving energy. Through an automated temperature control system, the need for manual intervention and monitoring can be reduced, thereby improving production efficiency. In addition, precise temperature control also helps to shorten the production cycle because production delays caused by temperature fluctuations can be avoided.

[0092] When performing specific temperature detection, different measurement methods are set for sensors at different stages. Since sensors generally measure the temperature information of corresponding points, but in actual measurement, it is necessary to measure the temperature information of the surface layer of the mold cavity and / or the center layer of the mold cavity, it is necessary to configure the corresponding temperature transfer formula to accurately detect the corresponding sensor signal.

[0093] More preferably, the controlling the working state of each heating element in the oil heating assembly and the electric heating assembly according to the third heating curve to cool the corresponding mold core assembly to ensure that the temperature in the cavity is cooled according to the set gradient, includes:

[0094] Acquire corresponding alloy material information, and determine corresponding heat loss parameters per unit time based on the alloy material information;

[0095] The corresponding temperature gradient information is determined according to the heat loss parameter per unit time and the heat-gradient calculation formula; the heat calculation formula is: ;in, is the thermal conductivity of the mold, F is the surface area of ​​the cavity, is the temperature gradient; is the heat loss parameter of the alloy material per unit time;

[0096] The temperature control mode of the oil heating component and the electric heating component is adjusted according to the temperature gradient information to ensure that the temperature in the cavity is cooled according to the set gradient.

[0097] The scheme of the embodiment of the present invention obtains alloy material information and determines the heat loss parameters per unit time based on this information, so that the system can customize the cooling process for different alloy materials. This customized method ensures that each alloy material can be cooled in the best way, thereby improving product quality and process reliability. The temperature gradient information is determined by the heat-gradient calculation formula, so that the system can accurately control the temperature gradient in the cavity. This precise control helps to avoid problems caused by excessive or insufficient temperature gradients, such as internal stress, deformation or cracking of the product, thereby further improving the performance of the product. According to the calculated temperature gradient information, the system can intelligently adjust the temperature control method of the oil heating component and the electric heating component. This intelligent adjustment not only ensures that the temperature in the cavity can be cooled according to the set gradient, but also improves the efficiency and automation of the entire cooling process. More preferably, the heating control method of the semi-solid forming device also includes:

[0098] Acquire mold model information, and divide the mold into a plurality of heating areas according to the mold model information, cavity information, and a heat transfer model, and each heating area is configured with at least one electric heating element or at least one oil heating element;

[0099] Determining the corresponding preset heating curve according to the temperature control stage includes:

[0100] Determining a preset heating curve for each heating zone according to the temperature control stage;

[0101] The real-time temperature curve is matched with the target heating curve, and the working state of the oil heating component and the electric heating component in the heating component is adjusted according to the matching result, including:

[0102] Comparing the real-time temperature curve of each heating zone with the target heating curve of each zone to determine the deviation of the temperature of each heating zone from the target temperature;

[0103] According to the comparison result, the power of the electric heating element and the heating oil pipe in each heating area is adjusted respectively so that the temperature of each area gradually approaches the target temperature.

[0104] The solution of the embodiment of the present invention divides the mold into multiple heating areas by obtaining mold model information and cavity information, and configures a heating element for each area, thereby realizing precise heating control of different areas of the mold. This control method helps to reduce temperature gradients and improve the quality and performance of molded parts. By matching the real-time temperature curve of each area with the target heating curve, temperature deviations can be discovered in a timely manner, and the power of the heating element can be adjusted according to the comparison results to ensure that the temperature of each area gradually approaches the target temperature. This real-time temperature monitoring and adjustment mechanism helps to improve the stability of the molding process and the product qualification rate. By accurately controlling the heating power of each area, unnecessary energy waste can be avoided and energy utilization efficiency can be improved. At the same time, reducing temperature fluctuations and overheating also helps to extend the service life of molds and equipment. This optimized heating control method can better adapt to different mold models, cavity structures and material properties, thereby improving the adaptability and flexibility of the process. For molded parts with complex shapes or high performance requirements, this control method is more advantageous.

[0105] During specific implementation, the power of the electric heaters and heating oil pipes in each area is dynamically adjusted according to the real-time feedback of the temperature in different areas of the mold; the heating speed between the oil heater and the electric heater is determined during setting, and the optimal working range of each heating component is determined according to the heating speed; the uniformity of temperature distribution and heating efficiency are optimized according to power allocation or heating sequence.

[0106] More preferably, before obtaining the temperature control stage of the current semi-solid forming device, the method further includes:

[0107] Acquire molding sample information and device model information of the current semi-solid molding device, wherein the device model information includes a first position information group of each oil heating element in the oil heating assembly and a second position information group of each electric heating element in the electric heating assembly;

[0108] The controlling the working state of the oil heating component and the electric heating component in the heating component according to the preset heating curve comprises:

[0109] Determine a corresponding heat transfer model according to the molding sample information, and determine a first heating power group of each oil heating element and a second heating power group of each electric heating element according to the preset heating curve, the heat transfer model, the first position information group of each oil heating element in the oil heating assembly, and the second position information group of each electric heating element in the electric heating assembly;

[0110] The working state of the corresponding oil heating element is controlled according to the first heating power group, and the working state of the corresponding electric heating element is controlled according to the second heating power group.

[0111] By acquiring the molding sample information of the current semi-solid molding device, the system can formulate personalized heating strategies for different samples. This strategy takes into account factors such as the material properties, shape, and size of the sample to ensure that the heating process is more in line with the needs of specific samples. And combined with the device model information, including the position information of each heating element in the oil heating component and the electric heating component, the system can accurately control the heating layout. This means that the system can optimize the heating effect according to the specific location of the heating element, ensuring that the critical area receives enough heat while avoiding overheating of non-critical areas. By controlling the working state of the corresponding heating element according to the calculated heating power group, the system achieves fine control of the heating process. This control method helps to reduce temperature fluctuations and deviations, thereby improving the stability of the molding process and product quality. Because the system can adjust the heating strategy according to different sample information and device model information, it has strong flexibility and adaptability. This flexibility enables the system to easily cope with a variety of different molding needs and production scenarios.

[0112] More preferably, the heating control method further includes:

[0113] Obtaining working status information, current parameter information, voltage parameter information and sensor parameter information of all heating components;

[0114] Inputting the working state information, current parameter information, voltage parameter information and sensor parameter information into a fault identification model for identification to determine the use state of the corresponding heating element;

[0115] If it is detected that all the heating elements are in good condition, the operating state of each heating element in the heating assembly is not adjusted;

[0116] If it is detected that the corresponding heating element is in a faulty state, the position information of the faulty heating element is determined, and the operating state information of the remaining heating elements is determined based on the position information.

[0117] By acquiring the working status information, current parameter information, voltage parameter information and sensor parameter information of all heating components, the system can realize comprehensive and real-time monitoring of the heating components. This comprehensive monitoring helps to timely discover potential faults and problems and improve the reliability of the system. It inputs the collected various parameter information into the fault identification model and uses the intelligent analysis ability of the model to accurately identify the fault status of the heating component. This accurate fault identification helps to reduce misjudgment and missed judgment and improve the accuracy of fault handling.

[0118] When it is detected that all heating elements are in good condition, the system will not make unnecessary adjustments, thus ensuring the continuity and stability of the heating process. When a heating element is detected to be faulty, the system will quickly determine the location information of the faulty heating element and adjust the operating status of the remaining heating elements based on the location information to ensure that the heating process can continue. This efficient fault response mechanism helps to reduce production interruption time and improve production efficiency. Because the system can accurately identify and locate faulty heating elements, maintenance personnel can quickly find the fault point and repair or replace it. This enhanced maintenance convenience helps to reduce maintenance time and costs and improve the maintainability of equipment.

[0119] More preferably, the fault identification model is constructed by the following steps:

[0120] Build a fault identification model through LSTM network;

[0121] The fault identification model is trained based on historical monitoring data to obtain a trained fault identification model; the historical monitoring data includes working state information, current parameter information, voltage parameter information and sensor parameter information;

[0122] Inputting the working state information, current parameter information, voltage parameter information and sensor parameter information into the fault identification model to obtain an operating state identification result;

[0123] The fault identification model of the LSTM network includes an input layer, a hidden layer and an output layer;

[0124] The training of the fault identification model based on the historical monitoring data to obtain the trained fault identification model includes:

[0125] Input the historical monitoring data into the corresponding first LSTM unit for model training to obtain an input layer;

[0126] Inputting the output result of the input layer into the second LSTM unit for model training to obtain a hidden layer;

[0127] The output result of the hidden layer is input into the third LSTM unit for recognition training to obtain the output layer, and the operating status information of the output layer is output as a result. The fault recognition model is obtained by continuously performing model training until the training requirements are met.

[0128] As a type of deep learning, LSTM network can automatically learn and extract deep features from data. The fault identification model built by LSTM can more effectively learn fault modes from historical monitoring data and improve the accuracy of fault identification. LSTM network is particularly suitable for processing time series data and can capture the time dependency in the data. In the heating control system, the working state information, current parameter information, voltage parameter information and sensor parameter information are all time-varying sequence data. LSTM network can process these data well and identify faults more accurately. By designing a multi-layer network structure including input layer, hidden layer and output layer, the model can gradually extract useful feature information from the original data, and then identify faults at a deeper level. This deep learning helps the model to identify and understand complex fault modes.

[0129] Since the model takes into account multiple factors such as working status information, current parameter information, voltage parameter information, and sensor parameter information, it can achieve comprehensive and integrated fault monitoring and identification of the heating component. This comprehensive monitoring helps to timely discover and deal with various potential fault problems to ensure the safe and stable operation of the system. The LSTM model here can implement the prediction of the working status of the corresponding heating component in the next stage, which is equivalent to being able to predict the corresponding status information in advance, so that technicians can make real-time adjustments to the working status of the entire heating component.

[0130] In the embodiment of the present invention, by obtaining the temperature control stage of the current semi-solid forming device and determining the corresponding preset heating curve according to the stage, accurate control of the heating process can be achieved. This control method can ensure that the device follows a predetermined temperature trajectory during the heating process, thereby meeting the temperature accuracy requirements of the semi-solid forming process.

[0131] Embodiment 2

[0132] like Figure 2-Figure 11 As shown, the present invention provides a semi-solid forming device with a heating function, comprising:

[0133] An upper mold assembly, the upper mold assembly includes an upper mold plate 10; a first oil heating assembly 411 and a first electric heating assembly 411 are arranged at the upper mold plate 10;

[0134] A lower mold assembly, the lower mold assembly includes a lower mold plate 20, and the lower mold plate 20 and the upper mold plate 10 are enclosed to form a first accommodating cavity, a second accommodating cavity, and a third accommodating cavity;

[0135] A barrel assembly 30, wherein the barrel assembly 30 is installed in the first accommodating chamber, and the barrel assembly 30 has a feed channel 33 for guiding the raw material into the mold core assembly 40;

[0136] A mold core assembly 40, the mold core assembly 40 is installed in the second accommodating cavity, the mold core assembly 40 has a feed channel 43, a cavity 44 and an overflow channel 45; the inlet end of the feed channel 43 is communicated with the feed channel 33, and the outlet end thereof is communicated with the cavity 44; the inlet end of the overflow channel 45 is communicated with the cavity 44; the mold core assembly 40 includes an electric heating assembly and an oil heating assembly; the electric heating assembly and the oil heating assembly are both used to heat the mold core assembly 40;

[0137] An overflow trough assembly 50, wherein the overflow trough assembly 50 is installed in the third accommodating chamber, and the overflow trough assembly 50 has an overflow buffer chamber 53, and a feed port of the overflow buffer chamber 53 is connected to a discharge port of the overflow channel 45;

[0138] A control module is electrically connected to the oil heating component and the electric heating component to control the working states of the oil heating component and the electric heating component.

[0139] In this embodiment, the overall temperature control accuracy and heating speed are improved by using a mixture of oil heating components and electric heating components; in general semi-solid forming devices, in order to consider different design directions, either oil heating control or electric heating control will be used. One advantage of using oil heating control is the accuracy of temperature control, but there is also a disadvantage that oil heating has a corresponding temperature limit, and the oil heating here is up to 350 degrees Celsius; for some alloy materials that require higher temperatures, it cannot be met. For those that require higher temperatures, electric heating is generally used, but the maximum temperature of the electric heating method can reach 900 degrees Celsius; however, there is a disadvantage of electric heating that the stability of temperature control is not good enough; for example, if the temperature needs to be controlled at 500 degrees, then the electric heating method will have a floating space, which may be a floating of 10 degrees Celsius, which will cause unexpected damage to semi-solid alloy materials with higher temperature requirements. Therefore, the scheme of the present application adopts a mixed method of oil heating and electric heating. In this way, the temperature can be increased by a mixed method of oil heating and electric heating during the heating stage, and in the temperature control stage, the temperature can be controlled by a set method, which can be pure oil heating or oil-electric mixed heating. This can make the overall temperature control more stable.

[0140] More preferably, the oil heating assembly includes a first oil heating assembly 411 and a second oil heating assembly 421, and the electric heating assembly includes a first electric heating assembly 411 and a second electric heating assembly 422.

[0141] The mold core assembly 40 includes an upper mold core 41 and a lower mold core 42. The upper mold core 41 is installed in the second upper receiving groove 12, and a first oil heating component 411 and a first electric heating component 411 are arranged at the upper mold core 41.

[0142] The lower mold core 42 is installed in the second lower accommodating groove 22, and the second oil heating component 421 and the second electric heating component 422 are arranged at the lower mold core 42; the first oil heating component 411, the second oil heating component 421, the first electric heating component 411 and the second electric heating component 422 are all electrically connected to the control module; the second lower accommodating groove 22 and the second upper accommodating groove 12 are enclosed to form the second accommodating cavity for accommodating the mold core assembly 40, and the upper mold core 41 and the lower mold core 42 are enclosed to form the feed channel 43, the cavity 44 and the overflow channel 45.

[0143] When designing the specific heating structure, corresponding heating mechanisms are provided at the upper mold core 41 and the lower mold core 42 respectively, so that the upper and lower parts can be heated simultaneously, ensuring that the overall heating is relatively uniform and ultimately making the product results more consistent.

[0144] On the basis of the above structure, the upper template 10 and the lower template 20 are respectively provided with corresponding first upper receiving grooves 11 and first lower receiving grooves 21, second upper receiving grooves 12 and second lower receiving grooves 22, and third upper receiving grooves 13 and third lower receiving grooves 23. This design enables the barrel assembly 30, the mold core assembly 40 and the overflow trough assembly 50 to be installed between the upper and lower templates 20, respectively, to form an independent and closed working space. When the upper and lower templates 20 are closed, these receiving grooves enclose to form a complete receiving cavity, providing stable support and positioning for each component. The barrel assembly 30 is composed of an upper barrel 31 and a lower barrel 32, which are respectively installed in the corresponding receiving grooves of the upper template 10 and the lower template 20. When the upper and lower templates 20 are closed, the upper barrel 31 and the lower barrel 32 enclose to form a feed channel 33. This design ensures that the raw material can smoothly enter the mold from the outside, and enter the feed flow channel 43 of the mold core assembly 40 after being guided by the barrel assembly 30. The mold core assembly 40 is composed of an upper mold core 41 and a lower mold core 42, which together form not only a feed channel 43, but also a cavity 44 and an overflow channel 45. The design of the feed channel 43 ensures that the raw material can evenly fill the cavity 44, and the shape of the cavity 44 directly determines the appearance of the final product. At the same time, the overflow channel 45 exists to timely discharge excess raw material and air during the raw material filling process to prevent excessive pressure in the cavity 44. The overflow trough assembly 50 is composed of an upper overflow trough body 51 and a lower overflow trough body 52, which together form an overflow buffer chamber 53. The function of this buffer chamber is to receive excess raw material flowing out of the overflow channel 45 of the mold core assembly 40, and to communicate with an external pipeline through its discharge port to guide the raw material out of the mold. This design effectively avoids the retention and waste of raw materials in the mold and improves production efficiency.

[0145] More preferably, the first oil heating component 411 and the second oil heating component 421 each include a plurality of oil heating elements, and the first electric heating component 411 and the second electric heating element each include a plurality of electric heating elements.

[0146] The multiple oil heating elements in the first oil heating assembly 411 are evenly distributed on the first plane; the multiple electric heating elements in the first heating assembly are evenly distributed on the second plane; the distance between the first plane and the cavity 44 is closer than the distance between the second plane and the cavity 44;

[0147] The multiple oil heating elements in the second oil heating assembly 421 are evenly distributed on the third plane; the multiple electric heating elements in the second heating assembly are evenly distributed on the fourth plane; the distance between the third plane and the cavity 44 is closer than the distance between the fourth plane and the cavity 44.

[0148] When designing the specific position, the oil heating assembly is generally arranged closer to the cavity 44 to facilitate uniform and stable heating. In this embodiment, the multiple oil heating elements in the first oil heating assembly 411 and the second oil heating assembly 421 are uniformly distributed on the first plane and the third plane, respectively, and the multiple electric heating elements in the first electric heating assembly 411 and the second electric heating assembly 422 are uniformly distributed on the second plane and the fourth plane, respectively. This uniform layout ensures that the raw materials around the cavity 44 can be subjected to uniform thermal effects, thereby avoiding molding defects caused by uneven heating and improving the quality and consistency of the molded products.

[0149] By designing that the distance between the first plane and the cavity 44 is closer than the distance between the second plane and the cavity 44, and the distance between the third plane and the cavity 44 is closer than the distance between the fourth plane and the cavity 44, a hierarchical heating effect is achieved. Since the oil heating element is closer to the cavity 44, it can mainly take on the initial rapid heating of the raw material, while the electric heating element can be used as an auxiliary heating means to further heat the raw material in detail. This hierarchical heating design helps to improve heating efficiency and heating accuracy. And because the heating stability of the oil is higher, that is, the temperature fluctuation is smaller, the final molding effect can be better.

[0150] And because the oil heater and the electric heater are independently controlled, their heating power and heating time can be flexibly adjusted according to actual needs, thereby achieving more sophisticated heating control. This design enables the device to adapt to the heating needs of different raw materials and different molding requirements, improving the versatility and flexibility of the device. By rationally arranging and optimizing the design of the heating components, the device can be made more energy-efficient and efficient during the heating process. For example, some heating elements can be selectively turned on or off according to the characteristics of the raw materials and molding requirements, thereby avoiding unnecessary energy waste. The design details of the above scheme further improve the heating performance, control accuracy and energy efficiency of the device, providing a strong guarantee for the high-quality implementation of the semi-solid molding process.

[0151] More preferably, the plurality of electric heating elements and the plurality of oil heating elements are alternately distributed along the left-right direction.

[0152] The solution of this embodiment can ensure that the heating energy is transferred more evenly and efficiently around the cavity 44 by distributing the electric heating elements and the oil heating elements alternately in the left and right directions. This layout avoids the concentration of heating elements, reduces the temperature difference and heat loss during the heat transfer process, and thus improves the heating efficiency and the utilization rate of thermal energy. The alternating distribution of electric heating elements and oil heating elements can produce a more uniform temperature field during the heating process, reducing the thermal stress of the raw materials caused by the temperature gradient. This helps to reduce the internal stress and deformation risk in the molded product and improve the mechanical properties and dimensional stability of the product.

[0153] Since the heating principles and response speeds of electric and oil heaters are different, alternating distribution can give full play to their respective advantages. For example, electric heaters have a fast response speed and can quickly increase the temperature of raw materials; while oil heaters can provide continuous and stable heat output. This combination makes the device more responsive and stable during the heating process. The alternating layout also helps to simplify the maintenance and repair of heating components. When a heater fails, it is easier to locate and replace the damaged parts, reducing downtime and maintenance costs. By alternating the distribution of electric and oil heaters in the left and right directions, the device has achieved significant technical improvements in heating uniformity, heat transfer efficiency, reducing thermal stress, enhancing heating responsiveness, and simplifying maintenance and repair.

[0154] More preferably, it further comprises a third electric heating component 423 electrically connected to the control module, and the third electric heating component 423 is arranged on the lower mold core 42 .

[0155] By setting the third electric heating assembly 423 in the lower mold core 42, more precise heating control can be performed on a specific area of ​​the cavity 44. This is particularly important for situations where it is necessary to locally adjust the temperature of the raw material or achieve a specific molding effect. For example, in some complex molding processes, different temperatures may need to be applied to different parts of the product to ensure that each part can achieve an ideal molding state.

[0156] The lower mold core 42 is a key component that is in direct contact with the raw materials during the molding process, and its temperature control has a direct impact on the molding quality of the product. By adding a third electric heating component 423 to the lower mold core 42, the mold core temperature can be more effectively controlled, thereby reducing molding defects caused by temperature fluctuations, such as shrinkage holes and cracks. This helps to improve the overall quality and pass rate of the product. The addition of the third electric heating component 423 makes the device more flexible in responding to different molding requirements. By adjusting the working state of the third electric heating component 423, it is easy to respond to the heating requirements of different raw materials, different product specifications and different molding conditions. This provides convenience for enterprises to quickly switch product types or adjust process parameters during the production process.

[0157] The third electric heating component 423 electrically connected to the control module can work in conjunction with other heating components to achieve more refined temperature control. By accurately adjusting the output power and heating time of each heating component, it can be ensured that the temperature of the raw material is always kept within the optimal range during the entire molding process. This not only helps to improve the molding accuracy and consistency of the product, but also helps to reduce energy consumption and production costs. By adding a third electric heating component 423 electrically connected to the control module at the lower mold core 42, the device has achieved significant technical improvements in local heating accuracy, molding quality, process flexibility, and refined control.

[0158] More preferably, it further comprises a thermal sensor 46 electrically connected to the control module, wherein the temperature measuring end of the thermal sensor 46 is arranged between the first plane and the second plane or the thermal sensor 46 is arranged between the adjacent electric heating element and the oil heating element.

[0159] By providing a thermal sensor 46 electrically connected to the control module, the temperature change during the heating process can be monitored in real time. The temperature measuring end of the thermal sensor 46 is located between the first plane and the second plane, or is arranged between adjacent electric heating elements and oil heating elements. These positions are key areas in the heating process and can accurately reflect the actual heating conditions of the raw materials. This real-time monitoring provides the control module with timely and accurate temperature data, which helps to achieve more sophisticated heating control.

[0160] Based on the real-time temperature data provided by the thermal sensor 46, the control module can accurately adjust the output power and heating time of each heating component to ensure that the raw material is always kept within the required temperature range during the molding process. This precise temperature control helps to improve the accuracy and quality of the molded product and reduce molding defects caused by temperature fluctuations. The presence of the thermal sensor 46 can also effectively prevent overheating during the heating process. Once it is detected that the temperature exceeds the set value, the control module can immediately adjust the heating strategy or initiate protective measures to prevent the raw material from being damaged or affecting the molding effect due to overheating. At the same time, this also helps to protect the heating components from high temperature damage and extend the service life of the equipment.

[0161] By monitoring the temperature in real time and adjusting the heating power as needed, unnecessary energy waste can be avoided. This on-demand heating method not only helps to reduce energy costs, but also improves heating efficiency, shortens the molding cycle, and thus improves overall production efficiency.

[0162] More preferably, a receiving space 60 for receiving impurities is provided between the feed channel 33 of the barrel assembly 30 and the feed flow channel 43 of the mold core assembly 40 .

[0163] On the basis of the above structure, the present embodiment forms a first accommodating cavity, a second accommodating cavity and a third accommodating cavity through the precise matching of the upper mold assembly and the lower mold assembly, providing a stable installation space for the barrel assembly 30, the mold core assembly 40 and the overflow trough assembly 50. The feed channel 33 of the barrel assembly 30 effectively guides the raw material into the mold core assembly 40, ensuring the continuity and stability of the raw material supply. The design of the feed flow channel 43, the cavity 44 and the overflow channel 45 of the mold core assembly 40 enables the raw material to flow into the cavity 44 evenly, and when necessary, the excess raw material is discharged through the overflow channel 45, thereby achieving efficient molding and precise control. The present invention sets a accommodating space 60 for accommodating impurities between the feed channel 33 and the feed flow channel 43. This design innovatively solves the problem of impurities that may exist in the raw material. Before the raw material enters the mold core assembly 40, the impurities can be effectively trapped in the accommodating space 60, thereby avoiding the influence of the impurities on the molding process and improving the quality and consistency of the finished product. The overflow channel 45 in the mold core assembly 40 of the present invention is connected to the overflow buffer chamber 53 of the overflow trough assembly 50, forming an effective overflow processing system. When there is too much raw material in the cavity 44, the excess raw material can enter the overflow buffer chamber 53 through the overflow channel 45, ensuring the pressure stability and cleanliness of the cavity 44 during the molding process. This design not only improves the molding efficiency, but also helps to extend the service life of the mold. In addition, the entire mold adopts a modular design, which makes the installation and disassembly of each component more convenient. This design not only improves production efficiency, but also facilitates the maintenance and care of the mold. When a component fails or needs to be replaced, it can be handled separately without disassembling the entire mold, thereby reducing maintenance costs and time.

[0164] More preferably, the feed channel 33 includes a first connecting hole 331 and a second connecting hole 332 which are connected in sequence; wherein, the feed port of the first connecting hole 331 is used to connect the semi-solid slurry conveying pipe joint, and the discharge port of the second connecting hole 332 is connected to the feed port of the feed flow channel 43; the radius of the first connecting hole 331 is greater than the radius of the second connecting hole 332, and a stepped stop surface 333 is formed at the connection between the first connecting hole 331 and the second connecting hole 332, and the stepped stop surface 333 is used to position the semi-solid slurry conveying pipe joint.

[0165] On the basis of the above structure, the design of the first connection hole 331 and the second connection hole 332 not only considers the flow characteristics of the slurry, but also takes into account the stability and convenience of the structure. The larger radius of the first connection hole 331 reduces the flow velocity at the slurry inlet and reduces the pressure loss, while the smaller radius of the second connection hole 332 helps to accelerate the slurry to flow to the cavity 44. The stepped stop surface 333 between the two not only changes the flow direction of the slurry, but more importantly, it acts as a positioning structure to ensure that the semi-solid slurry delivery pipe joint can be accurately and stably connected to the first connection hole 331. The stepped stop surface 333 can form a good match with the delivery pipe joint to prevent the joint from shifting or shaking during the connection process. This positioning function not only improves the stability of the connection, but also reduces the risk of slurry leakage caused by improper connection, ensuring that the slurry can enter the mold accurately. The presence of the stepped stop surface 333 also makes the installation of the delivery pipe joint simpler and faster. The operator only needs to align the joint with the feed port of the first connection hole 331 and then push it in along the stepped stop surface 333. At the same time, this design also facilitates future maintenance and replacement work, reducing maintenance costs and time costs.

[0166] More preferably, the accommodating space 60 is disposed between the second connecting hole 332 and the feed channel 43 , and a longitudinal cross-sectional area of ​​the accommodating space 60 is larger than a longitudinal cross-sectional area of ​​the second connecting hole 332 , and larger than a longitudinal cross-sectional area of ​​the feed channel 43 .

[0167] On the basis of the above structure, since the longitudinal cross-sectional area of ​​the accommodating space 60 is large, it can accommodate more impurities, thereby reducing the possibility of impurities entering the feed channel 43 or the cavity 44. This design effectively extends the cleaning cycle of the mold and improves production efficiency. The larger accommodating space 60 avoids the problem of obstruction of raw material flow due to the accumulation of impurities. The raw material can smoothly enter the feed channel 43 through the second connecting hole 332, ensuring the continuity and stability of the raw material flow. The existence of the accommodating space 60 reduces the wear of the second connecting hole 332 and the feed channel 43 by impurities, thereby increasing the service life of the mold. At the same time, this also reduces mold failures and downtime caused by impurities, and reduces production costs. During the use of the mold, the accommodating space 60 can be cleaned regularly to ensure the continuous and stable operation of the mold.

[0168] More preferably, the accommodating space 60 is enclosed by a first receiving groove 61 arranged at the outlet of the second connecting hole 332 and a second receiving groove 62 arranged at the feed inlet of the feed channel 43, the first receiving groove 61 and the second receiving groove 62 are coaxially arranged with the second connecting hole 332, and the first receiving groove 61 and the second receiving groove 62 have the same radius, the radius of the first receiving groove 61 is larger than the radius of the second connecting hole 332, and the radius of the second receiving groove 62 is larger than the width of the feed inlet of the feed channel 43;

[0169] The feed flow channel 43 is a flow channel in a waisted shape, wherein the middle portion is narrower and the two ends gradually expand.

[0170] On the basis of the above structure, the accommodating space 60 is enclosed by a first receiving groove 61 arranged at the outlet of the second connecting hole 332 and a second receiving groove 62 arranged at the feed inlet of the feed channel 43. This design not only expands the volume of the accommodating space 60, so that more impurities can be collected and accommodated, but also forms a continuous and closed space through the cooperation of the two receiving grooves, thereby preventing the diffusion and accumulation of impurities in the mold. The first receiving groove 61 and the second receiving groove 62 are coaxially arranged with the second connecting hole 332. This design ensures the continuity and stability of the slurry flow. Due to the coaxial arrangement, when the slurry flows out of the second connecting hole 332, it can smoothly enter the first receiving groove 61, then pass through the second receiving groove 62, and finally enter the feed channel 43. There is no abrupt turning or mutation in the entire flow process, which reduces the slurry flow resistance and improves the flow efficiency. The radius of the first receiving groove 61 is greater than the radius of the second connecting hole 332. This design enables the first receiving groove 61 to accommodate the slurry carrying impurities that flows out of the second connecting hole 332 without causing congestion or backflow of the slurry. At the same time, the radius of the second receiving groove 62 is greater than the width of the feed port of the feed channel 43, which also ensures that the impurities can be effectively collected and intercepted before entering the feed channel 43, preventing the impurities from clogging and wearing the feed channel 43. By designing the accommodating space 60, the mold can effectively collect and accommodate the impurities generated during long-term use, reducing the damage and destruction of the impurities to the inside of the mold. This not only extends the service life of the mold, but also reduces the maintenance cost of the mold.

[0171] Based on the above structure, the waist-shaped flow channel is characterized by a narrow middle portion and gradually widening at both ends. This design can produce a "focusing" effect, so that the slurry can be centrally guided and constrained when flowing through the flow channel, so that it can enter the mold cavity 44 more smoothly. The waist-shaped design helps to reduce eddy currents and backflows of the slurry during the flow process, reducing energy loss. At the same time, the narrow part in the middle of the flow channel can accelerate the flow rate of the slurry, so that it can obtain sufficient kinetic energy before reaching the mold cavity 44, thereby ensuring that the slurry can evenly and quickly fill the entire mold cavity 44.

[0172] In a preferred embodiment of the present invention, the waist-shaped flow channel includes a curved contraction section 431, a curved diffusion section 432 and a smooth transition section 433, wherein the width of the inlet end of the curved contraction section 431 is connected to the second receiving groove 62, and the width of the inlet end of the curved contraction section 431 is smaller than the diameter of the second receiving groove 62, the width of the outlet end of the curved contraction section 431 is smaller than the width of its inlet end, the width of the inlet end of the curved diffusion section 432 is the same as the width of the outlet end of the contraction section, and the width of its outlet end is greater than the width of its inlet end, the width of the smooth transition section 433 is the same as the width of the outlet end of the diffusion section, and the width of the outlet end of the smooth transition section 433 is the same as the width of the cavity 44.

[0173] On the basis of the above structure, this embodiment ensures that the slurry can smoothly and efficiently enter the mold cavity 44 by subdividing the flow channel into a curved contraction section 431, a curved diffusion section 432 and a smooth transition section 433, while effectively preventing the entry of impurities. The inlet end of the curved contraction section 431 is connected to the second receiving groove 62, and its width is less than the diameter of the second receiving groove 62. This design allows the slurry to gradually accelerate when flowing into the contraction section and be subjected to a certain compression, thereby increasing the flow rate and kinetic energy of the slurry. At the same time, the curved design helps to reduce flow resistance and allow the slurry to pass more smoothly. The inlet end of the curved diffusion section 432 is connected to the outlet end of the contraction section, and its width gradually increases. This design allows the slurry to gradually slow down and diffuse when flowing through the diffusion section, achieving a smooth transition from high flow rate to low flow rate. This not only reduces the impact and eddy current of the slurry at the entrance of the cavity 44, but also ensures that the slurry can evenly and fully fill the entire cavity 44. The smooth transition section 433 connects the diffusion section and the cavity 44, and its width is the same as the outlet end of the diffusion section, and gradually transitions to the same width as the cavity 44. This design ensures that the slurry can continue to maintain a stable flow rate and flow direction before entering the cavity 44, avoiding flow turbulence or impurities entering due to sudden changes. At the same time, the curved shape of the smooth transition section 433 also helps to reduce the resistance of the slurry during the flow process and improve the flow efficiency. Through the design of the waist-shaped flow channel, the slurry can enter the cavity 44 in a more uniform manner, avoiding uneven filling caused by uneven flow rate or unstable flow direction. This helps to improve the quality and consistency of the product.

[0174] In a preferred embodiment of the present invention, a protrusion 434 is provided at the connection between the smooth transition section 433 and the cavity 44 , and the width of the protrusion 434 is the same as the width of the cavity 44 .

[0175] On the basis of the above structure, the design of the raised portion 434 of this embodiment can change the trajectory and speed of the raw material flow, and play a role in guiding and adjusting the flow of the raw material. When the raw material enters the cavity 44 through the smooth transition section 433, the raised portion 434 acts as an obstacle, so that the raw material generates a diversion when it contacts the raised portion 434, so that it is more evenly distributed to various parts of the cavity 44. The width of the raised portion 434 is the same as the width of the cavity 44. This design ensures that the raised portion 434 can completely cover the entrance of the cavity 44, so that the raw material can be fully affected by the raised portion 434 when entering the cavity 44. This design avoids the concentrated flow or dead corner of the raw material at the entrance of the cavity 44, and ensures the uniform distribution of the raw material. By setting the raised portion 434, the raw material can be effectively dispersed and guided before entering the cavity 44, thereby reducing the flow resistance and eddy current phenomenon of the raw material in the cavity 44. This helps to improve the filling efficiency and uniformity of the raw material and reduce the generation of product defects. In addition, the design of the protrusion 434 enables the raw material to be filled into the cavity 44 more evenly, thereby improving the quality and consistency of the product.

[0176] In a preferred embodiment of the present invention, the overflow buffer chamber 53 is formed by an upper buffer groove 531 arranged on the bottom surface of the upper overflow trough body 51 and a lower buffer groove 532 arranged on the top surface of the lower overflow trough body 52. ​​A plurality of upper protrusions 533 arranged in parallel are arranged in the upper buffer groove 531, and a plurality of lower protrusions 534 arranged in parallel are arranged in the lower buffer groove 532. The plurality of upper protrusions 533 and the plurality of lower protrusions 534 are staggered with each other, so that a continuous wavy flow channel is formed in the overflow buffer chamber 53.

[0177] The design of the overflow buffer chamber 53 fully combines the characteristics of the slurry flow in the mold and the actual needs. Through the carefully arranged upper and lower buffer grooves 532 and protrusion structures, the buffering and uniform distribution of the slurry are effectively achieved. The overflow buffer chamber 53 is enclosed by the upper buffer groove 531 on the bottom surface of the upper overflow tank body 51 and the lower buffer groove 532 on the top surface of the lower overflow tank body 52. ​​This design not only utilizes the existing structure of the mold, but also expands the volume of the buffer chamber by adding buffer grooves, providing sufficient space for the slurry to buffer and flow. Multiple upper protrusions 533 and multiple lower protrusions 534 are arranged in a staggered manner, and this design forms a continuous wavy flow channel in the overflow buffer chamber 53. This flow channel design not only increases the flow distance and time of the slurry in the buffer chamber, but also enables the slurry to change direction and speed multiple times during the flow process, further promoting the buffering of the slurry. Through the continuous wavy flow channel, the slurry is fully buffered in the overflow buffer chamber 53. After being guided by the protrusions and grooves, the high-flow slurry gradually decreases in flow rate and becomes uniform. At the same time, the presence of the protrusions and grooves can also effectively break up large particles or bubbles in the slurry, preventing them from directly entering the mold cavity 44, thereby ensuring the quality and performance of the product.

[0178] In a preferred embodiment of the present invention, the upper overflow tank body 51 is further provided with an exhaust channel 511, one end of which is connected to the overflow buffer chamber 53, and the other end of which is connected to the external environment. The exhaust channel 511 is used to safely discharge the gas that may be generated in the overflow buffer chamber 53 to the external environment. This design helps to maintain the stability and safety of the tank body when handling liquid overflow, and prevents problems that may be caused by gas accumulation or excessive pressure.

[0179] In a preferred embodiment of the present invention, a driving mechanism 70 is further included, and the driving mechanism 70 is used to drive the upper mold to move closer to or away from the lower mold to close or open the mold. In this way, the introduction of the driving mechanism 70 makes the mold closing and opening process automated, greatly reducing the need for manual operation and improving production efficiency. The driving mechanism 70 can accurately control the distance between the upper mold and the lower mold, ensuring the accuracy of each mold closing and opening, thereby improving the stability and reliability of the molding process.

[0180] In a preferred embodiment of the present invention, a lower mold base 81 and four telescopic guide columns 82 are also included. The four telescopic guide columns 82 are symmetrically arranged on both sides of the lower mold base 81; the upper end of the telescopic guide column 82 passes through the lower mold plate 20 and is fixedly connected to the upper mold plate 10, and the lower end thereof is fixedly connected to the lower mold base 81; the lower mold plate 20 is fixedly installed on the top of the lower mold base 81. In this way, by symmetrically arranging four telescopic guide columns 82 on both sides of the lower mold base 81, the stability of the mold during the mold closing and mold opening process is significantly improved. The telescopic guide column 82 ensures the precise alignment of the upper mold plate 10 and the lower mold plate 20 during the movement process, and prevents molding errors caused by offset or shaking.

[0181] In a preferred embodiment of the present invention, an ejection mechanism is further included, and the ejection mechanism is used to eject the formed product from the cavity. In this way, after the forming process is completed, the ejection mechanism can quickly and accurately eject the product from the cavity, greatly reducing the time and labor intensity of manual removal, thereby improving production efficiency.
