Description

Technical Field

[0001] The present invention relates to the technical field of stamping dies, and specifically provides a stamping die for the production of refrigerator injection parts. Background Art

[0002] With the continuous development of modern social technology and the improvement of economic level, refrigerators are more and more widely used in life. Refrigerator injection parts are generally manufactured using stamping dies during the production process. Stamping refers to a workpiece forming processing method in which an external force is applied to a sheet through a press and a die, causing it to undergo plastic deformation or separation, thereby obtaining a workpiece with the required shape and size. However, when manufacturing refrigerator injection parts using stamping dies, air cylinders are generally used for stamping.

[0003] In the production process of refrigerator injection parts, the stamping die is not only a key tool for achieving the shape and dimensional accuracy of the product, but its performance and efficiency are also directly related to the cost-effectiveness and product competitiveness of the entire production line. Traditional stamping dies cannot control the stamping speed, and its adverse effects are far more than just the shortening of the die's own lifespan and the decline in stability. First of all, the high impact force caused by improper control of the stamping speed not only accelerates the wear of the die, but may also cause vibrations between the die and the stamping machine. This vibration will further affect the positioning accuracy and repeat accuracy of the die, making it difficult to ensure the dimensional consistency of the produced injection parts, increasing the scrap rate and rework rate. Moreover, the higher the stamping speed, the greater the impact force the die receives per unit time, and the shorter the time, the less time the impact energy has to be transmitted and released, easily causing the local stress to exceed the yield stress or fracture strength of the die material, resulting in the die being prone to fracture or plastic deformation failure. If the stamping speed is too slow, it will directly affect the production efficiency because the number of stampings completed per unit time decreases, which may lead to an extended production cycle and increased costs, and will cause the material to stay in the die for too long, thereby increasing the risk of material hardening. Especially during high-temperature stamping, it will cause uneven temperature and stress distribution of the material, affecting the forming quality. In addition, inaccurate temperature control will also lead to thermal stress problems during the injection process, increasing the risk of deformation of the injection parts, and may even cause defects such as surface cracks or internal bubbles; Therefore, based on the above search and combined with the existing technology, a stamping die for the production of refrigerator injection parts is proposed to solve the above problems.

Specific embodiments

[0016] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0017] In a typical embodiment of the present application, please refer to Figures 1 to 8 As shown, a stamping die for producing refrigerator injection - molded parts includes: a base 1, a workbench 2 is fixedly installed on the top surface of the base 1, a distribution box 3 is fixedly installed on the left side wall of the base 1, a controller 4 is fixedly installed on the front side wall of the base 1, an injection molding machine body 5 is fixedly installed on the top surface of the workbench 2, a feed pipe 6 is arranged on the top surface of the injection molding machine body 5, and the feed pipe 6 is used to pour plastic particles into the injection molding machine body 5. These plastic particles are raw materials required for producing refrigerator injection - molded parts. A discharge pipe 7 is arranged on the left side wall of the injection molding machine body 5, and the discharge pipe 7 is used to transport the molten plastic inside the injection molding machine body 5 into the female die of the lower mold 10; The stamping mechanism is arranged on the workbench 2. The stamping mechanism includes: a mounting seat 8, which is fixedly installed on the top surface of the workbench 2 and is located on the left side of the injection molding machine body 5. Four sliding rods 9 are arranged on the top surface of the mounting seat 8. A lower mold 10 is arranged on the top surface of the mounting seat 8. An upper mold 11 is arranged above the lower mold 10. A female mold is arranged on the top surface of the lower mold 10, and a male mold is arranged on the bottom surface of the upper mold 11, which is used to realize the stamping and forming of refrigerator injection parts. Sliders 12 are fixedly installed on both side walls of the lower mold 10 and the upper mold 11. The sliders 12 slide on the sliding rods 9. A top plate 13 is fixedly installed on the top surface of the sliding rods 9. A cylinder body 14 is fixedly installed on the top surface of the top plate 13. The stamping mechanism also includes a detection component.

[0018] With the above features, the stamping and forming of refrigerator injection parts can be carried out. Specifically, plastic particles are injected into the interior of the injection molding machine body 5 through the feed pipe 6. The injection molding machine body 5 heats and melts the plastic particles, and then conveys the molten plastic to the female mold in the lower mold 10 through the discharge pipe 7. At this time, the cylinder body 14 starts to work, and the output end of the cylinder body 14 descends, driving the upper mold 11 to stamp and form the molten plastic inside the lower mold 10. It is worth mentioning that during the production of refrigerator injection parts, the thickness of the plastic to be stamped has a direct impact on the stamping speed. The following is the specific relationship between the two: 1. The thickness of thin plastic parts is less than 3 mm: During the stamping of thin plastic parts, due to the thin material, local stress concentration is likely to occur under high-speed stamping, resulting in cracks or deformation. Therefore, the stamping speed should be controlled at a lower level to ensure the forming quality. The stamping speed is: 10 - 20 mm / s. Within this speed range, local stress concentration caused by too fast stamping speed can be effectively avoided, and at the same time, the production efficiency is guaranteed. 2. The thickness of medium-thickness plastic parts is between 3 mm and 8 mm: When stamping plastic parts with equal thickness, it is necessary to balance the stamping speed and the forming quality. Too fast stamping speed may lead to uneven material flow, while too slow speed will reduce the production efficiency. The stamping speed is: 20 - 40 mm / s. Within this speed range, it can ensure that the material flows evenly in the mold and avoid stamping defects caused by too fast speed. 3. The thickness of thick plastic parts is greater than 8 mm: When stamping thick plastic parts, due to the thick material, higher punching pressure and slower stamping speed are required to ensure that the material can fully fill the mold and avoid internal defects. The stamping speed is: 5 - 15 mm / s. Within this speed range, problems such as internal bubbles and cracks in the material caused by too fast stamping speed can be effectively avoided, and at the same time, the forming quality is guaranteed. The specific steps for accurately adjusting the stamping speed according to the thickness of the plastic to be stamped: 1. Plastic thickness detection: Before stamping, the ultrasonic thickness gauge 19 is used to detect the thickness of the plastic waiting to be stamped on the lower die 10. The ultrasonic thickness gauge 19 can quickly and accurately measure the thickness of the plastic and transmit the measurement data to the processor 20; 2. Data processing and analysis: The processor 20 receives the thickness data transmitted by the ultrasonic thickness gauge 19 and analyzes it according to the preset thickness - speed relationship model. The specific steps are as follows: Data calibration: Calibrate the data transmitted by the ultrasonic thickness gauge 19 to ensure the accuracy of the data. Thickness classification: Classify the workpieces to be stamped into thin plastic parts <3mm, medium - thickness plastic parts 3 - 8mm, and thick plastic parts >8mm according to the plastic thickness. Speed calculation: According to the classification of the plastic thickness and the specific relationship between thickness and speed, calculate the corresponding stamping speed. For example: If the plastic thickness is 2.5mm, the stamping speed is calculated as 15mm / s; If the plastic thickness is 5mm, the stamping speed is calculated as 30mm / s; If the plastic thickness is 10mm, the stamping speed is calculated as 10mm / s; 3. Stamping speed adjustment: The processor 20 transmits the calculated stamping speed data to the cylinder controller 21. The cylinder controller 21 accurately adjusts the stamping speed of the cylinder body 14 according to the received speed data through the transmission line 35. The specific steps are as follows: Cylinder parameter adjustment: The cylinder controller 21 adjusts parameters such as the air pressure and flow rate of the cylinder according to the calculated speed value to achieve precise speed control. Speed feedback and correction: During the stamping process, the actual stamping speed of the cylinder body 14 is monitored in real - time through a sensor, and the data is fed back to the processor 20. The processor 20 makes fine adjustments to the stamping speed according to the feedback data to ensure the accuracy of the stamping speed.

[0019] 4. Stamping process monitoring and optimization During the stamping process, the temperature inside the die is monitored in real - time through the temperature sensor 24 to ensure that the temperature inside the die is within a suitable range, avoiding molding problems caused by too high or too low temperature. At the same time, through the controller 4, various parameters during the stamping process, such as stamping speed, pressure, temperature, etc., are monitored in real - time, and optimized adjustments are made according to the actual situation. In addition, the discharge pipe 7 is made of high - temperature - resistant material, and the redundant discharge pipe 7 is placed between the injection molding machine body 5 and the mounting seat 8.

[0020] As a preferred implementation manner in this embodiment, please refer to Figures 1 to 5 As shown in the figure, the detection component includes: an L-shaped plate 15, the L-shaped plate 15 is fixedly installed on the side wall of the mounting seat 8, a protective shell 16 is fixedly installed on the top surface of the L-shaped plate 15, an L-shaped connecting rod 17 is arranged inside the protective shell 16 through a driving member, a fixing block 18 is fixedly installed on the left side wall of the L-shaped connecting rod 17, an ultrasonic thickness gauge 19 is fixedly installed on the left side wall of the fixing block 18, the detection component further includes: a processor 20, the processor 20 is fixedly installed on the inner wall of the protective shell 16, a cylinder controller 21 is fixedly installed on the inner wall of the protective shell 16, the cylinder controller 21 is located on the right side of the processor 20, a transmission line 35 is arranged on the top surface of the protective shell 16, one side of the transmission line 35 is connected to the cylinder controller 21, and the other side is connected to the cylinder body 14. The detection component further includes a connecting member.

[0021] Through the above features, the thickness of the plastic waiting to be stamped on the lower die 10 can be detected, and the speed of the cylinder body 14 can be adjusted according to the thickness of the plastic to be stamped. Specifically, when the driving member is started, the L-shaped connecting rod 17 can move back and forth, left and right. When the L-shaped connecting rod 17 moves, both the fixing block 18 on the front side wall and the ultrasonic thickness gauge 19 will move, so that the ultrasonic thickness gauge 19 detects the thickness of the plastic waiting to be stamped on the lower die 10. After the ultrasonic thickness gauge 19 finishes detecting, it will process the data through the processor 20 and then transmit it to the cylinder controller 21. The cylinder controller 21 adjusts the stamping speed of the cylinder body 14 through the transmission line 35 according to the data transmitted by the processor 20.

[0022] As a preferred implementation manner in this embodiment, please refer to Figure 5 and Figure 6 As shown in the figure, the connecting member includes: a fixing rod 22, the fixing rod 22 is fixedly installed on the bottom surface of the fixing block 18, connecting plates 23 are fixedly installed on the front and rear side walls of the fixing rod 22, one of the connecting plates 23 is connected to the end of the discharge pipe 7, and a temperature sensor 24 is fixedly installed on the side wall of the other connecting plate 23. A fan 25 is fixedly installed on the bottom surface of the fixing rod 22.

[0023] Through the above features, the molten plastic in the injection molding machine body 5 can be evenly injected into the female mold in the lower mold 10. Specifically, when the driving member drives the L-shaped connecting rod 17 to move, the fixed block 18 will move synchronously. The fixed rod 22 and the connecting plate 23 on the bottom surface of the fixed block 18 will both move. At this time, after the discharge pipe 7 injects the molten plastic evenly into the female mold of the lower mold 10, the fan 25 will be turned on to cool the molten plastic in the lower mold 10 until it reaches the specified temperature. The temperature sensor 24 can monitor the temperature of the molten plastic in real time. When it detects that the temperature has dropped to the appropriate temperature, the fan 25 will stop working. At this time, the moving member will drive the fan 25 and the temperature sensor 24 to return to the initial position to avoid affecting the stamping.

[0024] As a preferred implementation manner in this embodiment, please refer to Figures 6 to 8 As shown in the figure, the driving member includes: a fixing plate 26, the fixing plate 26 is arranged inside the protective shell 16. A moving groove 27 is opened on the top surface of the fixing plate 26. The inner wall of the moving groove 27 is rotatably connected with a first threaded rod 28. A moving block 29 is threadedly connected to the outer surface of the first threaded rod 28. The moving block 29 slides in the moving groove 27. The top surface of the moving block 29 is connected to the bottom surface of the L-shaped connecting rod 17. A driving motor 30 is fixedly installed on the right side wall of the fixing plate 26. The output shaft of the driving motor 30 is connected to the right side wall of the moving groove 27. The driving member further includes: a driving motor 31, the driving motor 31 is fixedly installed on the front side wall of the protective shell 16. A sliding groove 32 is opened inside the protective shell 16. The inner wall of the sliding groove 32 is rotatably connected with a second threaded rod 33. A sliding block 34 is threadedly connected to the outer surface of the second threaded rod 33. The sliding block 34 slides in the sliding groove 32. The top surface of the sliding block 34 is connected to the bottom surface of the fixing plate 26. The output shaft of the driving motor 31 is connected to the front side wall of the second threaded rod 33.

[0025] Through the above features, the L-shaped connecting rod 17 can be moved. Specifically, when the L-shaped connecting rod 17 needs to move back and forth, only need to turn on the driving motor 31 to make the second threaded rod 33 connected to the output shaft of the driving motor 31 rotate, so that the sliding block 34 threadedly connected to the outer surface of the second threaded rod 33 moves in the sliding groove 32. During the movement of the sliding block 34, the fixing plate 26 will also move synchronously. During the movement of the fixing plate 26, the moving block 29 in the fixing plate 26 and the L-shaped connecting rod 17 connected to the top surface of the moving block 29 will both move. When the L-shaped connecting rod 17 needs to move left and right, only need to turn on the driving motor 30 to make the first threaded rod 28 connected to the output shaft of the driving motor 30 rotate. At this time, the moving block 29 connected to the outer surface of the first threaded rod 28 will move in the moving groove 27, so that the L-shaped connecting rod 17 connected to the top surface of the moving block 29 moves synchronously; It is worth mentioning that the specific steps for the controller 4 to monitor various parameters such as stamping speed, pressure, temperature, etc. in real time during the stamping process and optimize and adjust according to the actual situation are as follows: Before the start of the stamping process, initialize and set various parameters through the controller 4 to ensure that the equipment operates according to the preset process requirements. The specific steps are as follows: Start the equipment: Connect the power supply and start the entire stamping die system Parameter input: Input or call the preset process parameters through the interface of the controller 4, including: Stamping speed: According to the thickness of the plastic to be stamped, input the corresponding stamping speed, such as 10 - 20 mm / s for thin plastic parts, 20 - 40 mm / s for medium-thickness plastic parts, and 5 - 15 mm / s for thick plastic parts.

The monitored parameters include: Stamping speed monitoring: Through the speed sensor on the cylinder body 14, monitor the stamping speed in real time.

[0034] 3. Parameter optimization and adjustment According to the parameter data monitored in real time, optimize and adjust through the controller 4 to ensure the stability of the stamping process and product quality. The specific steps are as follows: Stamping speed adjustment: If the stamping speed monitored in real time is lower than the preset value, it may affect production efficiency. The controller 4 will prompt the operator or automatically adjust the parameters of the cylinder controller 21 to increase the stamping speed; If the stamping speed is higher than the preset value, it may cause stress concentration in the mold or product quality problems. The controller 4 will automatically reduce the stamping speed.

[0035] Stamping force adjustment: If the pressure monitored in real time is lower than the preset value, it may cause incomplete forming. The controller 4 will prompt the operator or automatically increase the pressure. If the pressure is too high, it may cause mold damage or product deformation. The controller 4 will automatically reduce the pressure.

[0036] Temperature adjustment: If the mold temperature is higher than the preset range, the controller 4 will start the cooling fan 25 in advance for cooling. If the temperature is lower than the preset range, the controller 4 will prompt the operator to check the heating system or adjust the heating power.

[0037] Other parameter adjustments: If the molten plastic temperature of the injection molding machine body 5 is too high or too low, the controller 4 will prompt the operator to adjust the heating power or cooling system. If the working time of the cooling fan 25 is too long or too short, the controller 4 will adjust its working time or temperature threshold.

[0038] 4. Abnormal handling and alarm During the monitoring process, if it is found that the parameters exceed the normal range or abnormal situations occur, the controller 4 will give an alarm and take corresponding measures: Alarm prompt: If the stamping speed, pressure or temperature exceeds the preset range, the controller 4 will emit an audible and visual alarm signal to remind the operator to pay attention.

[0039] Automatic shutdown: If the parameter abnormality is serious and may cause damage to the equipment or product quality, the controller 4 will automatically stop the stamping process to protect the equipment and product.

[0040] Fault diagnosis: The controller 4 will record the abnormal data and time for technicians to conduct fault diagnosis and analysis.

[0041] 5. Recording and analysis After the stamping process is completed, record and analyze the parameter data of the entire process through the controller 4 to provide a basis for subsequent optimization: Data recording: The controller 4 will automatically record the change curves of parameters such as speed, pressure, and temperature during the stamping process.

[0042] Data analysis: Through the analysis function of the controller 4, statistical analysis is performed on the parameter data to identify potential problems and optimization space.

[0043] Report generation: The controller 4 can generate reports on the stamping process for technicians to reference and archive.

[0044] Working principle: During use, first pour plastic particles into the interior of the injection molding machine body 5 through the feed pipe 6. After the injection molding machine body 5 is started, it will heat and melt these plastic particles to form molten plastic. Subsequently, this molten plastic will be evenly transported through the discharge pipe 7 into the female mold within the lower mold 10. The discharge pipe 7 is made of high-temperature resistant material, ensuring the stability and safety of the molten plastic during transportation. The excess part of the discharge pipe 7 is cleverly arranged between the injection molding machine body 5 and the mounting seat 8, neither affecting normal operation nor ensuring the compactness of the structure. Then, the detection component starts to function. The driving part is activated, driving the L-shaped connecting rod 17 to move back and forth, left and right within the protective shell 16. The fixed block 18 and the ultrasonic thickness gauge 19 on the front side of the L-shaped connecting rod 17 also move accordingly, enabling the ultrasonic thickness gauge 19 to accurately detect the thickness of the plastic waiting to be stamped on the lower mold 10. After the detection is completed, the ultrasonic thickness gauge 19 transmits the data to the processor 20 for processing. The processor 20 quickly analyzes the received data and transmits the processing result to the cylinder controller 21. The cylinder controller 21 then accurately adjusts the stamping speed of the cylinder body 14 based on this data through the transmission line 35 to ensure that the stamped refrigerator injection parts have the required thickness and quality. At the same time, the connecting piece also plays an important role. When the L-shaped connecting rod 17 moves, the fixed rod 22 and the connecting plate 23 move accordingly, ensuring that the discharge pipe 7 can evenly inject the molten plastic into the female mold of the lower mold 10. After the injection molding is completed, the fan 25 is started to cool the molten plastic in the lower mold 10. The temperature sensor 24 monitors the temperature of the molten plastic in real-time. When the temperature drops to the appropriate range, the fan 25 stops working. At this time, the moving part drives the fan 25 and the temperature sensor 24 to return to the initial position to avoid affecting subsequent stamping work. During the entire stamping process, the controller 4 can monitor and adjust various parameters in real-time to ensure the stability and efficiency of the production process. The distribution box 3 provides power support for the entire system, ensuring the normal operation of the equipment.

[0045] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
