Description

Technical Field

[0001] This invention relates to the field of automotive parts injection molding technology, and specifically to an automotive parts injection mold with a mold closing monitoring structure. Background Technology

[0002] Injection molds for automotive parts are specialized molds used to produce automotive components. Molten plastic is injected into the mold cavity under high pressure, and after cooling and solidification, it forms a part that meets design requirements. It is a core tool in the production of plastic parts in automobile manufacturing, directly affecting the precision, quality, and production efficiency of the parts. The use of recycled plastic waste in the injection molding process for automotive parts offers significant benefits in terms of environmental protection, economy, technology, and society. It meets consumer demand for environmentally friendly products and enhances brand premium. Furthermore, as automobiles are mass-market consumer goods, using recycled plastic waste to produce reliable parts subtly conveys the concept of environmental protection.

[0003] In the injection molding process of automotive parts, the mold closing condition directly determines the molding quality of the parts. If the mold doesn't close properly, molten plastic will overflow from the mold gaps during high-pressure injection, causing defects such as flash and burrs, affecting the appearance and dimensional accuracy of the parts. Traditional monitoring of the mold closing condition relies on the experience and skills of operators, which is subjective and uncertain. Manual inspection is difficult to perform in real-time and accurately, especially in high-speed, continuous production processes, where problems often go undetected, leading to production accidents and quality issues. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art by proposing an injection mold for automotive parts with a mold closing monitoring structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An injection mold for automotive parts with a mold closing monitoring structure includes a housing, a stationary mold, and a moving mold. The stationary mold and the moving mold are both installed inside the housing. A first detection mechanism for visually detecting the mold closing state of the stationary mold and the moving mold is provided at the top of the housing. Two moving rods are provided at the top of the housing, and a second detection mechanism for detecting the mold closing pressure of the stationary mold and the moving mold is provided at the bottom of each of the two moving rods.

[0006] Optionally, the first detection mechanism includes a rectangular groove at the center of the top of the housing, an installation block is provided inside the rectangular groove, and first grooves are provided on both inner walls of the rectangular groove. Movable blocks are installed inside the two first grooves, and the ends of the two movable blocks that are close to each other are connected to the installation block.

[0007] Optionally, a lead screw is rotatably mounted inside one of the first grooves, a movable block is threadedly connected to the outer wall of the lead screw, an electric push rod is mounted on the top of the mounting block, the telescopic end of the electric push rod passes through the mounting block and is connected to a first mounting plate, and two industrial cameras are mounted on the bottom of the first mounting plate.

[0008] Optionally, a second mounting plate is threaded onto each of the two outer walls of the first mounting plate using two bolts, and a cleaning pad is installed on the outer wall of each of the two second mounting plates on the side away from the first mounting plate.

[0009] Optionally, two first sliding grooves are formed on the outer walls of both sides of the top of the housing. A first slider is installed inside each of the two first sliding grooves, and the end of each first slider away from the first sliding groove is connected to its corresponding moving rod.

[0010] Optionally, the second detection mechanism includes a movable plate disposed at the bottom of two movable rods. A second slide groove is provided at the bottom of each of the two movable rods. A second slider is installed inside each of the two second slide grooves. The ends of the two second sliders away from the second slide grooves are connected to their corresponding movable plates.

[0011] Optionally, a third sliding groove is provided on the outer wall of the two movable plates that are close to each other. A third slider is installed inside the two third sliding grooves. A rotating block is rotatably installed on the end of the two third sliders that is away from the third sliding groove. A rotating plate is rotatably installed on one end of the two rotating blocks. Two electromagnets are installed on the outer wall of the two rotating blocks that are close to the rotating plate.

[0012] Optionally, two second grooves are formed on one side of the outer wall of each of the two rotating plates, and a double-ended screw is rotatably installed inside the two second grooves. A movable seat is threaded onto the outer wall of each of the two double-ended screws.

[0013] Optionally, a conveying roller is rotatably mounted between the two movable seats, and a drive motor with its output end connected to the rotating part of the conveying roller is mounted on one side of the outer wall of each of the two movable seats. A through groove of the same length as the two conveying rollers is opened in the center of the interior of the two rotating plates.

[0014] Optionally, two electric telescopic rods are installed on the other outer wall of each of the two rotating plates. A hollow plate is installed on the telescopic end of the two electric telescopic rods. Multiple nozzles are installed on the outer wall of the hollow plate near the through groove. A connection end for connecting to an externally preset infusion device is installed on the outer wall of the hollow plate away from the rotating plate.

[0015] The beneficial effects of this invention are: 1. In this invention, during the injection molding of automotive parts using an injection mold, the first and second detection mechanisms work together to automatically determine whether the mold closing state of the static and dynamic molds is qualified. This allows workers to adjust the parameters of the static and dynamic molds or the injection molding machine in a timely manner based on the detection results, thereby improving the mold closing state, reducing impurity residue, and avoiding reliance on manual inspection of the mold closing state, which could lead to difficulties in ensuring the quality of automotive parts injection molding and the occurrence of safety accidents.

[0016] 2. In this invention, after the second detection mechanism detects the mold closing status of the static mold and the moving mold with pressure-sensitive paper, it can continue to use the pressure-sensitive paper to hold and fix the injection-molded automotive parts. In conjunction with the industrial camera of the first detection mechanism, the automotive parts are identified and detected, achieving the effect of automatic detection of the surface quality of the injection-molded automotive parts. Based on the results of the surface quality detection of the automotive parts, the staff can quickly check whether the adjusted mold closing status of the static mold and the moving mold is qualified, ensuring the normal use of the static mold and the moving mold in the future.

[0017] 3. In this invention, if two industrial cameras detect defects on the surface of automotive parts, the cooperation between relevant components of the second detection mechanism can drive multiple nozzles to spray cleaning agent comprehensively and evenly onto the surfaces of the stationary and moving molds. After the cleaning agent has reacted for a period of time, the first detection mechanism drives the two cleaning pads of the first mounting plate to automatically clean the surfaces of the stationary and moving molds, eliminating the need for manual cleaning of the surfaces of the stationary and moving molds with tools, thus improving the cleaning efficiency of the moving and stationary molds.

[0018] 4. In this invention, since two hollow plates are provided on the outer walls of the two rotating plates, after detecting the mold closing pressure state of the static and dynamic molds using pressure sensing paper, if it is not necessary to use pressure sensing paper to hold the injection-molded automotive parts, the surface of the pressure sensing paper can be directly identified and detected by two industrial cameras, and the degree of contamination on the surface of the pressure sensing paper can be detected simultaneously. If there is slight contamination on the surface of the pressure sensing paper, multiple nozzles on one side of the two hollow plates can be controlled to spray cleaning agent on both sides of the pressure sensing paper. With the help of the staff near the housing pulling one end of the pressure sensing paper, or by using two conveying rollers to transport the pressure sensing paper, the cleaning agent can be fully and evenly contacted on both sides of the pressure sensing paper. This makes it convenient for the staff to clean the pressure sensing paper with slight surface contamination, so that the pressure sensing paper can be reused and waste can be reduced.

[0022] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Reference Figures 1-12 An injection mold for automotive parts with a mold closing monitoring structure includes a housing 1, a stationary mold 2, and a moving mold 3. The stationary mold 2 and the moving mold 3 are both installed inside the housing 1. A first detection mechanism for visually detecting the mold closing state of the stationary mold 2 and the moving mold 3 is provided at the top of the housing 1. Two moving rods 6 are provided at the top of the housing 1. A second detection mechanism for detecting the mold closing pressure of the stationary mold 2 and the moving mold 3 is provided at the bottom of each of the two moving rods 6.

[0024] As a technical optimization of the present invention, the first detection mechanism includes a rectangular groove 4 located at the center of the top of the housing 1. A mounting block 13 is disposed inside the rectangular groove 4. First grooves 9 are formed on both inner walls of the rectangular groove 4. Movable blocks 11 are installed inside each of the two first grooves 9, with the adjacent ends of the two movable blocks 11 connected to the mounting block 13. While the two movable blocks 11 move back and forth within their respective first grooves 9, they can simultaneously drive the mounting block 13 to move back and forth within the rectangular groove 4 for adjustment.

[0025] As a technical optimization of the present invention, a lead screw 12 is rotatably installed inside one of the first grooves 9, and a moving block 11 is threadedly connected to the outer wall of the lead screw 12. An electric push rod 5 is installed on the top of the mounting block 13, and the telescopic end of the electric push rod 5 passes through the mounting block 13 and is connected to a first mounting plate 14. Two industrial cameras 15 are installed at the bottom of the first mounting plate 14. In actual use, a first driving device is preset on one side of the outer wall of the housing 1. The output end of the first driving device is connected to one end of the lead screw 12, thereby driving the lead screw 12 to rotate inside one of the first grooves 9, which in turn drives one of the moving blocks 11 and the mounting block 13 to move and adjust synchronously. During the extension and retraction process, the telescopic end of the electric push rod 5 can drive the first mounting plate 14 and the two industrial cameras 15 to move and adjust synchronously up and down. Both industrial cameras 15 are industrial cameras of the prior art model Dalsa Ladybug6.

[0026] As a technical optimization of the present invention, two second mounting plates 17 are threadedly installed on both outer walls of the first mounting plate 14 using two bolts 16. Cleaning pads 18 are installed on the outer walls of the two second mounting plates 17 on the side away from the first mounting plate 14. The bolts 16 are used to install and fix the second mounting plates 17, facilitating quick assembly and disassembly, and allowing for easy replacement of the cleaning pads 18.

[0027] As a technical optimization of the present invention, two first sliding grooves 10 are formed on the outer walls of both sides of the top of the housing 1. A first slider 19 is installed inside each of the two first sliding grooves 10, and the end of each first slider 19 away from the first sliding groove 10 is connected to its corresponding moving rod 6. A first linear motor is pre-installed inside each of the two first sliding grooves 10. The two first linear motors can drive the two first sliders 19 to move back and forth within their respective first sliding grooves 10 for adjustment, thereby driving the moving rod 6 to move back and forth on the top of the housing 1 for adjustment.

[0028] As an optimized technical solution of the present invention, the second detection mechanism includes a movable plate 7 disposed at the bottom of two movable rods 6. Each of the two movable rods 6 has a second sliding groove 20 at its bottom. A second slider 21 is installed inside each of the two second sliding grooves 20, and the end of each second slider 21 away from the second sliding groove 20 is connected to its corresponding movable plate 7. A second linear motor is pre-installed inside each of the two second sliding grooves 20. The two second linear motors can drive the two second sliders 21 to move back and forth within their respective second sliding grooves 20, thereby causing the two movable plates 7 to move back and forth at the bottom of the two movable rods 6 for adjustment.

[0029] As a technical optimization of the present invention, a third sliding groove 23 is provided on the outer wall of the two moving plates 7 that are close to each other. A third slider 24 is installed inside the two third sliding grooves 23. A rotating block 25 is rotatably installed on the end of the two third sliders 24 that is away from the third sliding groove 23. A rotating plate 8 is rotatably installed on one end of the two rotating blocks 25. Two electromagnets 26 are installed on the outer wall of the two rotating blocks 25 that are close to the rotating plate 8. Each of the two third slide grooves 23 is equipped with a third linear motor, which can drive the two third sliders 24 to move up and down within the corresponding third slide grooves 23 for adjustment. Each of the two third sliders 24 is equipped with a second driving device, the output of which is connected to the rotating parts of the two rotating blocks 25, thereby driving the two rotating blocks 25 and the rotating plate 8 to rotate for adjustment. Each of the two rotating blocks 25 is equipped with a third driving device, the output of which is connected to the rotating parts of the two rotating plates 8, thereby driving the two rotating plates 8 to rotate for adjustment. When the two rotating plates 8 are in their original vertical state, the two energized electromagnets 26 can be used to magnetically limit the rotation of the rotating plates 8, thereby improving the stability of the vertical rotating plates 8.

[0030] As a technical optimization of the present invention, two second grooves 31 are formed on one side of the outer wall of each of the two rotating plates 8. A double-ended screw 32 is rotatably installed inside each of the two second grooves 31, and a movable seat 33 is threaded onto the outer wall of each of the two double-ended screws 32. Two fourth driving devices are pre-set on one side of the outer wall of each of the two rotating plates 8. The output ends of the two fourth driving devices are respectively connected to one end of each of the two double-ended screws 32, thereby driving the two double-ended screws 32 to rotate and adjust within the corresponding second grooves 31. This allows the two double-ended screws 32 to move and adjust their two movable seats 33 in the direction of approaching or moving away from each other during rotation.

[0031] As a technical optimization of the present invention, a conveying roller 22 is rotatably mounted between two movable seats 33. A drive motor 34, whose output end is connected to the rotating part of the conveying roller 22, is mounted on one outer wall of each of the two movable seats 33. A through groove 30, the same length as the two conveying rollers 22, is centrally located inside each of the two rotating plates 8. While the two movable seats 33 are moving and adjusting, they can simultaneously drive the two conveying rollers 22 to move towards or away from each other. Furthermore, a drive motor 34 is mounted on one outer wall of each of the two movable seats 33, and after starting, the two drive motors 34 can drive the corresponding conveying roller 22 to rotate and adjust.

[0032] As a technical optimization of the present invention, two electric telescopic rods 35 are installed on the outer wall of each of the two rotating plates 8. A hollow plate 27 is installed at the telescopic ends of the two electric telescopic rods 35. Multiple nozzles 28 are installed on the outer wall of the hollow plate 27 near the through groove 30, and a connecting end 29 for connecting to an externally pre-installed infusion device is installed on the outer wall of the hollow plate 27 away from the rotating plate 8. During the telescopic process of the two electric telescopic rods 35, the hollow plate 27 and the multiple nozzles 28 can be moved and adjusted on the other side of the rotating plate 8. After connecting the tubing of the externally pre-installed infusion device to the connecting end 29, the relevant cleaning agent in the infusion device can be delivered into the interior of the hollow plate 27 and discharged outwards through the multiple nozzles 28.

[0033] In this invention, when the user uses the device, the recycled plastic waste is processed through sorting, cleaning, crushing, granulation and raw material modification, and then the processed plastic waste is transported to the barrel of the injection molding machine, where the plastic waste is heated and melted by the high temperature inside the barrel. Finally, the melted plastic is injected into the stationary mold 2 and the moving mold 3 in the mold closing state. The molded car parts are reset as the moving mold 3 moves and fall naturally downwards from between the stationary mold 2 and the moving mold 3, thus realizing the injection molding process of the car parts.

[0034] During the injection molding of automotive parts by the cooperation of the stationary mold 2 and the moving mold 3, the telescopic end of the electric push rod 5 can be controlled to extend downward, driving the first mounting plate 14 and the two industrial cameras 15 at its bottom to monitor the mold closing status of the stationary mold 2 and the moving mold 3 in real time. After the moving mold 3 moves and resets, the surfaces of the stationary mold 2 and the moving mold 3, as well as the injection-molded automotive parts, can be photographed to detect whether there are defects in the injection-molded automotive parts and whether the parts stick to the mold or have residue. If the two industrial cameras 15 detect related abnormalities, the injection mold abnormality detection system will prohibit mold closing and issue an alarm so that the staff can quickly carry out related repairs on the injection mold.

[0035] Because the two industrial cameras 15 of the first detection mechanism are used to monitor the mold closing state of the stationary mold 2 and the moving mold 3, the different shapes of the mold cavities inside the mold affect the monitoring, making it impossible for the industrial cameras 15 to comprehensively capture and monitor the mold cavity in real time. Before installing the new stationary mold 2 and the moving mold 3 inside the housing 1 for mold closing test, or after the mold has been used for a period of time, to ensure that the injection-molded automotive parts are discharged downwards, the two first sliders 19 can be controlled to move the corresponding moving rods 6 together towards the middle position of the housing 1 inside the corresponding first slide grooves 10, and to move the moving plates 7 at the bottom of the two moving rods 6 and the vertical rotating plate 8 together towards the same direction. The pressure-sensing paper is placed in the through groove 30 inside one of the rotating plates 8 after both rotating plates 8 have moved close to the stationary mold 2. The two double-headed screws 32 on one of the rotating plates 8 are then controlled to rotate synchronously, driving the two moving seats 33 and the two conveying rollers 22 to move closer together. This ensures that the two conveying rollers 22 stably hold the pressure-sensing paper. Then, as the two drive motors 34 drive the two conveying rollers 22 to rotate, the pressure-sensing paper located between the two conveying rollers 22 slowly moves to the front of the stationary mold 2. One end of the pressure-sensing paper enters between the other two conveying rollers 22 and is stably held by them. Then, the control... The moving mold 3 and the stationary mold 2 are closed, ensuring that the pressure sensing paper is tightly clamped and fixed by the closed molds 2 and 3. After the closed state is maintained for a period of time, the moving mold 3 is moved back to its original position. Then, the two third sliders 24 are moved downward together in their corresponding third grooves 23 to adjust the pressure sensing paper held by the two rotating plates 8 and the conveying rollers 22. The pressure sensing paper is slowly moved downward to a suitable height in front of the stationary mold 2. Then, the two rotating blocks 25 are controlled to rotate the two rotating plates 8 downward together to a horizontal position, causing the pressure sensing paper to rotate horizontally below the stationary mold 2. Finally, the telescopic end of the electric push rod 5 is extended downward, causing the two industrial cameras 15 to move downward. Move the device above the pressure-sensing paper, and in conjunction with the lead screw 12, drive the mounting block 13 and two industrial cameras 15 to move back and forth for adjustment. This ensures that the two industrial cameras 15 can fully identify and detect the surface of the horizontal pressure-sensing paper, allowing them to automatically observe the color distribution on the pressure-sensing paper and determine whether the mold closing pressure of the stationary mold 2 and the moving mold 3 is uniform. If uneven pressure distribution is found on the pressure-sensing paper, it may indicate that the stationary mold 2 and the moving mold 3 have problems with poor mold closing or excessive local stress. These problems may cause plastic impurities to remain on the surface of the stationary mold 2 and the moving mold 3. Subsequently, the operator can improve the mold closing state and reduce impurity residue by adjusting the parameters of the stationary mold 2 and the moving mold 3 or the injection molding machine.

[0036] Through the cooperation of the second detection mechanism and the pressure sensing paper, the mold closing state detection of the stationary mold 2 and the moving mold 3 is completed. The operator adjusts the relevant parameters of the stationary mold 2 and the moving mold 3. To verify whether the injection molding of the automotive parts by the adjusted stationary mold 2 and the moving mold 3 is qualified, the two rotating plates 8 of the second detection mechanism are kept horizontally below the stationary mold 2, and both ends of the pressure sensing paper are still clamped and fixed by the two conveying rollers 22. After the stationary mold 2 and the moving mold 3 have injection molded the automotive parts, as the moving mold 3 moves and resets, the automotive parts fall downwards onto the top of the horizontal pressure sensing paper. As the two moving rods 6 drive the two moving plates 7 and the rotating plates 8 to continue moving closer together, the two conveying rollers 22 above the two rotating plates 8 can clamp and fix the automotive parts that have fallen onto the top of the pressure sensing paper. After ensuring that the two conveying rollers 22 have stably clamped the automotive parts, the two double-headed screws 32 on the two rotating plates 8 are controlled to rotate and adjust, driving the corresponding... The two conveying rollers 22 move away from each other, releasing the clamping and fixing of the two ends of the pressure sensing paper. After the staff near the housing 1 removes the pressure sensing paper, the electric push rod 5 can be controlled again to drive the two industrial cameras 15 to identify and detect the surface of the injection-molded car parts. Then, with the help of the two rotating blocks 25, the rotating plate 8 is driven to rotate upward and reset, and the two second sliders 21 drive the two moving plates 7 to move to a position close to the moving mold 3 inside the corresponding second slide groove 20. At this time, with the help of the two rotating blocks 25, the rotating plate 8 can be driven to rotate downward clockwise to a horizontal state, which can drive the clamped car parts to rotate 180 degrees, so that the two industrial cameras 15 can identify and detect the other side of the car parts, achieving a more comprehensive detection effect on the surface quality of the injection-molded car parts. Based on the results of the surface quality detection of the car parts, the staff can quickly check whether the adjusted static mold 2 and moving mold 3 are qualified, ensuring the normal use of static mold 2 and moving mold 3 in the future.

[0037] As mentioned above, the two industrial cameras 15 detected defects on the surface of the automotive parts, with some plastic adhering to the mold cavity surface of the stationary mold 2 or the moving mold 3. Figure 2As shown, one of the second sliders 21 can be controlled to move the moving plate 7 and the rotating plate 8 to a position close to the moving mold 3 within the corresponding second slide groove 20. Then, the third drive device inside the two rotating blocks 25 is controlled to drive the two rotating plates 8 to rotate downwards together to a horizontal state, so that the two rotating plates 8 are respectively located in the front position of the stationary mold 2 and the moving mold 3. Then, the telescopic ends of the two electric telescopic rods 35 on one side of the outer wall of the two rotating plates 8 are controlled to extend together, pushing the corresponding hollow plate 27 to move upwards and extend. After that, the external preset infusion device is activated, so that multiple nozzles 28 on one side of the two hollow plates 27 can spray cleaning agent onto the surface of the stationary mold 2 and the moving mold 3. With the help of the two third sliders 24 moving up and down within the corresponding third slide groove 23, the multiple nozzles 28 can be driven to thoroughly and evenly clean the surface. The cleaning agent is sprayed onto the surfaces of the stationary mold 2 and the moving mold 3. After the cleaning agent reacts for a period of time, the two rotating plates 8 are controlled to rotate and reset. Then, the telescopic end of the electric push rod 5 is controlled to extend downward, and the screw 12 drives the installation block 13 to move and adjust. This causes the cleaning pad 18 on one side of the first installation plate 14 to come into contact with the front of the stationary mold 2. As the telescopic end of the electric push rod 5 repeatedly extends and retracts, the cleaning pad 18 can automatically clean the cleaning agent and impurities on the surface of the stationary mold 2. The impurities and cleaning agent on the surface of the moving mold 3 can be cleaned automatically by the position adjustment of the first installation plate 14 driven by the screw 12. This allows the cleaning pad 18 on the other side of the first installation plate 14 to clean the surface of the moving mold 3 automatically, eliminating the need for manual cleaning of the surfaces of the stationary mold 2 and the moving mold 3 with the help of tools, thus improving the cleaning efficiency of the moving mold 2 and the stationary mold 3.

[0038] Since two hollow plates 27 are provided on the outer walls of the two rotating plates 8, after the pressure-sensing paper is used to detect the mold closing pressure of the stationary mold 2 and the moving mold 3, if the pressure-sensing paper is not needed to hold the injection-molded automotive parts, the two industrial cameras 15 can be used to directly identify and detect the surface of the pressure-sensing paper, and simultaneously detect the degree of contamination on the surface of the pressure-sensing paper. If there is slight contamination on the surface of the pressure-sensing paper, multiple nozzles 28 on the side of the two hollow plates 27 that are close to each other can be controlled to spray cleaning agent on both sides of the pressure-sensing paper. With the help of the staff near the housing 1 pulling one end of the pressure-sensing paper, or by using two conveying rollers 22 to transport the pressure-sensing paper, the cleaning agent can be fully and evenly contacted on both sides of the pressure-sensing paper, which is convenient for the staff to clean the pressure-sensing paper with slight contamination on the surface. This allows the pressure-sensing paper to be reused and reduces waste.
