Description

Technical Field

[0001] The present invention relates to the technical field of starter casting, and more specifically, to a casting mold for an automotive starter. Background Art

[0002] In the automotive manufacturing industry, as a core component, the casting quality of the starter directly affects the performance and reliability of the entire vehicle. Traditional casting molds for automotive starters mostly adopt a single-station design, and processes such as feeding, cooling, and demolding need to be completed sequentially, resulting in low production efficiency and difficulty in meeting the requirements of large-scale production. At the same time, the temperature control system of existing molds relies on manual experience for adjustment and lacks a real-time monitoring mechanism. Defects such as shrinkage cavities and cracks are often caused by uneven material temperatures; pressure control also mostly uses fixed parameters and cannot be dynamically adjusted according to material characteristics, easily causing problems such as insufficient filling or overpressure deformation. In addition, the demolding process of traditional molds mostly relies on manual assistance, which not only has low efficiency but also poses a risk of damage to the castings, further reducing the yield rate.

[0003] Based on this, with the trend of intelligent and efficient development in the automotive industry, the existing casting mold technology has become difficult to meet new requirements. On the one hand, the market's dual requirements for increasing the output and quality of starters also require the mold to have the ability of multi-station parallel production; on the other hand, the popularization of intelligent manufacturing technology has promoted the transformation of the casting process towards automation and precision, and the disadvantages of traditional molds lacking intelligent monitoring and closed-loop control have become increasingly prominent. Therefore, the research and development of a new type of casting mold integrating multi-station coordination, intelligent temperature control, and pressure monitoring has become the key to solving the industry's pain points and promoting the upgrading of automotive parts manufacturing.

[0010] Preferably, the intelligent control system includes a central controller, a temperature control module, a pressure control module, a motion control module, and a data storage module. The temperature control module is connected to a temperature sensor network distributed at key parts of the mold. The temperature sensor network includes: A thermocouple sensor arranged on the inner wall of the storage box, which is used to monitor the temperature of the molten material in real time; An infrared temperature sensor arranged inside the piston, which is used to detect the working temperature of the heating element; A thin-film temperature sensor arranged on the surface of the top mold, which is used to monitor the surface temperature of the mold; A PT100 thermal resistor arranged at the entrance of the cooling chamber, which is used to control the temperature of the coolant; A thermocouple array embedded inside the side mold, which is used to detect the temperature difference at each part of the mold.

[0015] Compared with the prior art, the advantages of the present invention are as follows: Efficient multi-station production structure: Most of the existing casting molds are single-station, with low production efficiency. This mold has four casting platforms arranged circumferentially on the base, and with the cooperation of a rotating feeding system, multi-station parallel operation can be achieved. When cooling and demolding are carried out at one station, other stations can synchronously carry out processes such as injection and pressurization, the production efficiency is increased by 4 times, and the production cycle of a single casting is shortened by 30 - 40%, significantly improving the production capacity.

[0016] Intelligent and precise temperature control system: The temperature control of traditional molds relies on manual experience and is prone to casting defects. This mold deploys temperature sensors at key parts such as the storage tank, heating ring, and top mold. Combining PID and fuzzy control algorithms, the temperature fluctuation is controlled within ±3°C. The temperature difference is monitored in real time through the thermocouple array in the side mold, and the coolant flow rate is dynamically adjusted to make the temperature difference between different parts of the mold ≤ 50°C, effectively reducing problems such as shrinkage cavities and cracks, and the qualified rate of castings is increased to over 98%.

[0017] Integrated Pressure and Displacement Detection: In existing molds, the pressure control parameters are fixed and it is difficult to adapt to material changes. The detection mechanism of this mold monitors the displacement of the detection block through a distance sensor, and feeds back the cavity pressure in real time. The intelligent system adjusts the propulsion speed of the extrusion rod accordingly to achieve closed-loop pressure control. When abnormal displacement is detected, the system can give an early warning in time and adjust the process parameters, effectively preventing defects such as insufficient material filling and ensuring the stability of casting quality.

[0025] Specifically, the intelligent control system includes a central controller, a temperature control module, a pressure control module, a motion control module, and a data storage module.

[0026] Specifically, the intelligent control system connects each sensor and actuator through a distributed field controller PLC. The field controller includes a temperature acquisition unit, a pressure acquisition unit, an IO control unit, and a communication unit. The communication unit supports the RS485 bus and the wireless Bluetooth protocol to achieve data transmission of sensors for rotating parts. The temperature control module adjusts the power of the heating element based on the PID control algorithm to maintain the temperature in the storage bin 14 within the range of the target value ±3°C.

[0027] Specifically, the intelligent control system further includes a fuzzy control unit. The fuzzy control unit dynamically adjusts the coolant flow rate of the cooling chamber 32 according to the temperature gradient between the top mold 3 and the side mold 21 to ensure that the temperature difference between different parts of the mold is ≤50°C. The central controller incorporates a prediction algorithm that predicts the thermal fatigue life of the mold based on the historical data of the temperature sensors and the mold stress model. When the temperature of a critical part fluctuates abnormally, a preventive maintenance prompt is generated. The fuzzy control unit adjusts the coolant flow rate according to the mold temperature gradient. The central controller analyzes the historical data through the prediction algorithm, anticipates the mold life, and generates a maintenance prompt. The intelligent cooling optimizes the heat distribution and reduces casting defects. Preventive maintenance extends the mold life, reduces downtime costs, and the maintenance frequency.

[0028] Specifically, the intelligent control system works in coordination with the mechanical structure of the mold to implement the following control logic: During the material melting stage, the injection timing of the material is controlled according to the temperature of the storage bin 14. During the casting stage, the temperature of the piston 18 and the blanking speed are synchronously controlled. During the cooling stage, the coolant flow rate is adjusted based on the temperature gradient. During the demolding stage, the ejection mechanism is triggered after confirming that the mold temperature has dropped to the safety threshold. The intelligent control system automatically coordinates the mechanical structure and process parameters according to the melting, injection, cooling, and demolding in the casting stage. For example, the temperature of the heating ring and the blanking speed are synchronously controlled during injection, and the safe temperature of the mold is confirmed before demolding. The whole process is automatically coordinated and controlled, reducing human error, ensuring process stability, and improving the overall production efficiency and casting quality.

[0029] Specifically, the intelligent control system automatically puts the heating elements and the cooling system of non-working stations into sleep mode according to the production rhythm. When a station switching signal is detected, the process parameters are quickly restored to the target values through a preheating algorithm. The intelligent control system analyzes the historical production data through a machine learning algorithm and automatically optimizes the heating timing, cooling rate, and pressurization parameters. The intelligent system puts the equipment of non-working stations into sleep mode according to the production rhythm and quickly preheats when switching stations. The machine learning algorithm analyzes the historical data, optimizes the heating, cooling, and pressurization parameters. The dynamic energy-saving mode reduces energy consumption. The self-optimization of parameters reduces the number of trial molds, shortens the production cycle, and reduces production costs.
