Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of stamping dies, in particular to a stamping die for refrigerator injection molding part production. BACKGROUND

[0002] With the continuous development of modern social technology and the improvement of economic level, the application of refrigerators in life is becoming more and more widespread. In the production process of refrigerator injection molding parts, stamping dies are generally used for production. Stamping refers to the method of workpiece forming processing by applying external force to sheet metal through a press and a die to make it produce plastic deformation or separate from it, thereby obtaining the required shape and size. However, when using stamping dies to produce refrigerator injection molding parts, a cylinder is generally used for stamping.

[0003] In the production process of refrigerator injection molding parts, the stamping die is not only the key tool to realize the shape and size precision of the product, but also directly related to the cost-effectiveness and product competitiveness of the entire production line. The traditional stamping die cannot control the stamping speed, and its adverse effects are far beyond the shortening of the service life and the decline of the stability of the die itself. First of all, the improper control of the stamping speed leads to high impact force, which not only accelerates the wear of the die, but also may cause vibration between the die and the stamping machine. This vibration will further affect the positioning accuracy and repeatability of the die, making it difficult to ensure the dimensional consistency of the produced injection molding parts, increasing the scrap rate and rework rate. In addition, the higher the stamping speed, the greater the impact force the die receives in unit time, and the shorter the time, the impact energy cannot be transferred and released in time, which is easy to cause the local stress to exceed the yield stress or breaking strength of the die material, leading to the die breaking or plastic deformation failure. If the stamping speed is too slow, it will directly affect the production efficiency, because the number of stamping completed in unit time is reduced, which may lead to the extension of the production cycle and the increase of the cost, and will also cause the material to stay in the die for too long, thereby increasing the risk of material hardening. Especially in the process of 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 cause thermal stress problems in the injection molding process, increasing the risk of deformation of the injection molding parts, and even may cause surface cracks or internal bubbles and other defects;

[0004] Therefore, based on the above search and combined with the prior art, a stamping die for refrigerator injection molding part production is proposed to solve the above problems. SUMMARY

[0016] 1. In this invention, by setting up a detection component, the stamping speed can be precisely adjusted, which effectively avoids problems such as local stress concentration, fracture or plastic deformation failure of the mold caused by excessive stamping speed. This significantly improves the service life and stability of the mold. At the same time, the precise stamping speed control also ensures that the ideal forming effect can be achieved in each stamping, reducing problems such as unstable quality of stamped parts, dimensional variation and increased burrs and scrap caused by uneven speed.

[0018] 3. In this invention, the inclusion of a connector ensures that the molten plastic can be injected evenly and stably into the cavity of the lower mold. The clever cooperation between the connector and the discharge pipe achieves precise delivery of the molten plastic, avoiding quality problems in the injection molded parts caused by uneven delivery. At the same time, the combined use of the fan and temperature sensor provides double protection for the molding quality of the injection molded parts. The fan can quickly reduce the temperature of the molten plastic in the lower mold, while the temperature sensor can monitor the temperature change of the molten plastic in real time, ensuring that it solidifies within a suitable temperature range, thereby improving the molding effect and surface quality of the injection molded parts.

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0029] In a typical embodiment of the present application, please refer to Figures 1-8 ​​As shown, a refrigerator injection molding production stamping die, including: base 1, the top surface of base 1 is fixedly installed with workbench 2, the left side wall of base 1 is fixedly installed with distribution box 3, the front side wall of base 1 is fixedly installed with controller 4, the top surface of workbench 2 is fixedly installed with injection molding machine body 5, the top surface of injection molding machine body 5 is provided with feeding pipe 6, feeding pipe 6 is used for pouring plastic particles into injection molding machine body 5, these plastic particles are raw materials needed for producing refrigerator injection molding, the left side wall of injection molding machine body 5 is provided with discharge pipe 7, discharge pipe 7 is used for conveying molten plastic inside injection molding machine body 5 into the female die of lower die 10;

[0030] The stamping mechanism is arranged on the workbench 2, and the stamping mechanism comprises: a mounting seat 8 fixedly installed on the top surface of the workbench 2 and located on the left side of the injection molding machine body 5, four slide rods 9 are arranged on the top surface of the mounting seat 8, a lower die 10 is arranged on the top surface of the mounting seat 8, an upper die 11 is arranged above the lower die 10, a female die is arranged on the top surface of the lower die 10, and a male die is arranged on the bottom surface of the upper die 11, so as to realize the stamping forming of the refrigerator injection molding, and slide blocks 12 are fixedly installed on the two side walls of the lower die 10 and the upper die 11, the slide blocks 12 slide on the slide rods 9, a top plate 13 is fixedly installed on the top surface of the slide rod 9, a cylinder body 14 is fixedly installed on the top surface of the top plate 13, and the stamping mechanism further comprises a detection assembly.

[0031] Through the above features, the refrigerator injection molding can be stamping formed, specifically, the plastic particles are injected into the inside of the injection molding machine body 5 through the feeding pipe 6, the injection molding machine body 5 melts the plastic particles, and then the molten plastic is conveyed into the female die in the lower die 10 through the discharge pipe 7, at this time, the cylinder body 14 starts to work, the output end of the cylinder body 14 descends, and drives the upper die 11 to stamp and form the molten plastic inside the lower die 10;

[0032] It is worth mentioning that in the production process of the refrigerator injection molding, the thickness of the plastic to be stamped has a direct impact on the stamping speed, and the specific relationship between the two is as follows:

[0033] 1. The thickness of the thin plastic part is less than 3mm:

[0034] In the stamping process of the thin plastic part, due to the thin material, local stress concentration is easy to occur under high-speed stamping, which may cause cracks or deformation, therefore, the stamping speed should be controlled at a low level to ensure the forming quality, and the stamping speed is: 10-20mm / s, within this speed range, local stress concentration caused by too fast stamping speed can be effectively avoided, and the production efficiency is ensured;

[0035] 2. The thickness of the medium-thickness plastic part is 3mm-8mm:

[0036] When stamping plastic parts of equal thickness, it is necessary to balance the stamping speed and the forming quality. Too fast stamping speed can lead to uneven material flow, while too slow speed will reduce production efficiency. The stamping speed is 20-40 mm / s, which can ensure uniform material flow in the mold and avoid stamping defects caused by excessive speed.

[0037] 3. Thick plastic parts with thickness greater than 8mm:

[0038] When stamping thick plastic parts, higher stamping force 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, which can effectively avoid internal bubbles, cracks and other problems caused by excessive stamping speed, while ensuring the forming quality.

[0039] The specific steps of adjusting the stamping speed according to the thickness of the plastic to be stamped are as follows:

[0040] 1. Plastic thickness detection:

[0041] Before stamping, the thickness of the plastic to be stamped on the lower mold 10 is detected by the ultrasonic thickness gauge 19. The ultrasonic thickness gauge 19 can quickly and accurately measure the thickness of the plastic and transmit the measurement data to the processor 20.

[0042] 2. Data processing and analysis:

[0043] The processor 20 receives the thickness data transmitted by the ultrasonic thickness gauge 19 and analyzes it according to the pre-set thickness and speed relationship model. The specific steps are as follows:

[0044] Data calibration: calibrate the data transmitted by the ultrasonic thickness gauge 19 to ensure the accuracy of the data,

[0045] Thickness classification: classify the plastic parts to be stamped into thin plastic parts <3mm, medium thickness plastic parts 3-8mm and thick plastic parts >8mm,

[0046] Speed calculation: according to the classification of the plastic thickness, combined with the specific relationship between thickness and speed, calculate the corresponding stamping speed, for example:

[0047] If the thickness of the plastic is 2.5mm, the stamping speed is calculated as 15mm / s;

[0048] If the thickness of the plastic is 5mm, the stamping speed is calculated as 30mm / s;

[0049] If the thickness of the plastic is 10mm, the stamping speed is calculated as 10mm / s;

[0050] 3. Stamping speed adjustment:

[0051] The processor 20 transmits the calculated stamping speed data to the cylinder controller 21, which 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:

[0052] Cylinder parameter adjustment: The cylinder controller 21 adjusts the cylinder's air pressure, flow, and other parameters according to the calculated speed value to achieve precise speed control.

[0053] Speed feedback and correction: During the stamping process, the actual stamping speed of the cylinder body 14 is monitored in real time by the sensor, and the data is fed back to the processor 20. The processor 20 adjusts the stamping speed according to the feedback data to ensure the accuracy of the stamping speed.

[0054] 4. Stamping process monitoring and optimization

[0055] During the stamping process, the temperature inside the mold is monitored in real time by the temperature sensor 24 to ensure that the temperature inside the mold is within the appropriate range, avoiding problems caused by excessive or insufficient temperature,

[0056] At the same time, the manipulator 4 monitors various parameters during the stamping process, such as stamping speed, pressure, temperature, etc., and optimizes and adjusts according to the actual situation,

[0057] In addition, the discharge pipe 7 is made of high-temperature-resistant material, and the excess discharge pipe 7 is placed between the injection molding machine body 5 and the mounting seat 8.

[0058] As a preferred embodiment in this embodiment, please refer to Figures 1-5 As shown in the figure, the detection assembly includes: an L-shaped plate 15 fixedly installed on the side wall of the mounting seat 8, and the top surface of the L-shaped plate 15 is fixedly installed with a protective shell 16, the inside of the protective shell 16 is provided with an L-shaped connecting rod 17 through a driving member, the left side wall of the L-shaped connecting rod 17 is fixedly installed with a fixed block 18, and the left side wall of the fixed block 18 is fixedly installed with an ultrasonic thickness gauge 19, the detection assembly further includes: a processor 20 fixedly installed on the inner wall of the protective shell 16, the inner wall of the protective shell 16 is fixedly installed with a cylinder controller 21, the cylinder controller 21 is located on the right side of the processor 20, the top surface of the protective shell 16 is provided with a transmission line 35, one side of the transmission line 35 is connected with the cylinder controller 21, and the other side is connected with the cylinder body 14, and the detection assembly further includes a connecting member.

Specifically, the driving member is started, so that the L-shaped connecting rod 17 can move forward and backward and left and right. When the L-shaped connecting rod 17 moves, the fixed block 18 on the front side wall and the ultrasonic thickness gauge 19 will also move, so that the ultrasonic thickness gauge 19 detects the thickness of the plastic waiting to be stamped on the lower mold 10. After the ultrasonic thickness gauge 19 is detected, the data is processed by the processor 20 and then transmitted to the cylinder controller 21. The cylinder controller 21 adjusts the stamping speed of the cylinder body 14 according to the data transmitted by the processor 20 through the transmission line 35.

Specifically, when the driving member drives the L-shaped connecting rod 17 to move, the fixed block 18 will move synchronously, and the fixed rod 22 and the connecting plate 23 on the bottom surface of the fixed block 18 will move. At this time, the discharge pipe 7 can uniformly inject molten plastic into the concave mold of the lower mold 10, and at this time the fan 25 will be started to cool the molten plastic in the lower mold 10 to a specified temperature. The temperature sensor 24 can monitor the temperature of the molten plastic in real time. When the temperature is detected to be reduced to a suitable temperature, the fan 25 will stop working. At this time, the moving member drives the fan 25 and the temperature sensor 24 to return to the initial position, so as to avoid affecting the stamping.

[0063] Through the above characteristics, the L-shaped connecting rod 17 can be moved. Specifically, when it is needed to move the L-shaped connecting rod 17 forward and backward, the driving motor two 31 is started, the threaded rod two 33 connected with the output shaft of the driving motor two 31 is rotated, the sliding block 34 threadedly connected with the outer surface of the threaded rod two 33 is moved in the sliding groove 32, in the process of moving the sliding block 34, the fixed plate 26 is also moved synchronously, in the process of moving the fixed plate 26, the moving block 29 in the fixed plate 26 and the L-shaped connecting rod 17 connected with the top surface of the moving block 29 are moved, when it is needed to move the L-shaped connecting rod 17 left and right, the driving motor one 30 is started, the threaded rod one 28 connected with the output shaft of the driving motor one 30 is rotated, at this time, the moving block 29 connected with the outer surface of the threaded rod one 28 is moved in the moving groove 27, so that the L-shaped connecting rod 17 connected with the top surface of the moving block 29 is moved synchronously.

[0064] It is worth mentioning that the manipulator 4 monitors various parameters such as stamping speed, pressure and temperature in the stamping process in real time, and optimizes and adjusts the specific steps according to the actual situation:

[0065] Before the stamping process starts, the parameters are initialized and set through the manipulator 4 to ensure that the equipment operates according to the preset process requirements, and the specific steps are as follows:

[0066] Start the equipment: turn on the power and start the entire stamping die system

[0067] Parameter input: input or call the preset process parameters through the interface of the manipulator 4, including:

[0068] Punching speed: According to the thickness of the plastic to be punched, input the corresponding punching speed, such as thin plastic parts 10-20mm / s, medium thickness plastic parts 20-40mm / s, thick plastic parts 5-15mm / s.
