Description

Technical Field

[0001] This invention relates to the field of mold wear detection technology, specifically to a wear detection mechanism for automotive interior parts molds. Background Technology

[0002] Automotive interior parts molds operate under constant high-frequency opening and closing, high-pressure filling of molten materials, reciprocating bonding and pressure bearing, and alternating temperature and humidity changes during normal mass production. It is necessary to monitor the wear status of key areas of the mold in real time throughout the process, and simultaneously retain complete wear condition traceability data to ensure that the mold is always in a compliant and high-precision operating range, adapting to the needs of continuous and uninterrupted production of large-volume, standardized automotive interior parts. The wear detection function of automotive interior parts molds can detect the wear of the mold through laser measurement, thereby accurately identifying the wear amount, surface scratches and deformation defects of key parts such as cavities, parting surfaces, inserts, and guide pillars. Existing wear detection mechanisms for automotive interior parts molds, such as the one disclosed in CN117308788B, involve a wear detection device for automotive interior parts molds. By setting a transmission rod, it is easy to drive the rotation of the driven shaft through the cooperation of a worm gear and worm wheel. This facilitates the stable rotation of the optical scanner driven by the transmission rod to perform comprehensive inspection of the mold, which is beneficial for wear and flaw detection of automotive interior parts molds and makes it more convenient to use. However, the aforementioned existing technology has a limited detection range, which means it cannot detect large interior component molds, thus limiting its use. In addition, the existing technology mentioned above does not have a structure for removing dust from the space above the mold, which will cause the detection to be affected by dust, resulting in inaccurate detection results. Therefore, a wear detection mechanism for automotive interior parts molds is needed to solve the above problems. Summary of the Invention

[0003] The purpose of this invention is to provide a wear detection mechanism for automotive interior part molds, in order to solve the problems mentioned in the background art regarding the limited detection range and the inability to avoid the influence of dust on the detection results of existing automotive interior part mold wear detection devices.

The two pressure-bearing frames correspond to the two ends of the screw respectively, and the axis of the screw is collinear with the axis of the pressure-bearing frame.

[0008] Preferably, the mounting bracket has connecting pipes fixedly connected to the outer sides of both the left and right ends, and a connecting rod is inserted into the open end of the connecting pipe. The end of the connecting rod inserted into the connecting pipe is seamlessly slidably connected to the inner side of the connecting pipe, and the end of the connecting rod outside the connecting pipe is connected to the corresponding pressure-bearing frame.

[0009] Preferably, a support tube is fixedly connected to the inner side of the support frame, and the support tubes are evenly distributed on the side of the support frame facing the opening end of the connecting tube. A support rod extends movably into the opening end of the support tube, and the end of the support rod extending into the support tube is seamlessly slidably connected to the inner side of the support tube. A toothed plate frame is meshed with both the upper and lower sides of the driven gear, and the lower end of the toothed plate frame is connected to the end of the support rod outside the support tube. A T-shaped rod movably passes through the lower end of the toothed plate frame, and the T-shaped rod is fixedly connected to the inner side of the support frame. A return spring is provided on the outer side of the T-shaped rod, connecting the lower end of the toothed plate frame and the inner side of the support frame.

[0010] Preferably, the connecting pipe is connected to the corresponding support pipe via an air guide pipe, and the connecting pipe, the corresponding support pipe, and the corresponding air guide pipe are filled with hydraulic oil.

[0011] Preferably, the follow-up jet mechanism further includes a telescopic tube provided on the outside of the limiting rod, and there are two telescopic tubes.

[0014] Compared with the prior art, the beneficial effects of the present invention are: the wear detection mechanism for automotive interior part molds has a sufficiently large detection range using a photosensitive scanner, thus enabling it to be applied to wear detection of larger-sized automotive interior part molds. Furthermore, when performing wear detection on automotive interior part molds using a photosensitive scanner, a gentle breeze is continuously blown upwards towards the mold, thereby removing dust from the space above the mold and ensuring that the dust content in the space above the mold is sufficiently low during photosensitive scanner detection, thus contributing to improved accuracy of the detection results. 1. By using a reciprocating lead screw and screw, the optical scanner can be driven to move in the front-back and left-right directions. Compared with the optical scanner, which can only move in one direction, this greatly increases the detection range, thus enabling the mold wear detection mechanism to be applied to larger-sized automotive interior parts molds. 2. The follow-up jet mechanism enables the optical scanner to move synchronously with the disc end on the extrusion frame, thereby applying extrusion and tension forces to the two telescopic tubes respectively. This causes the jet nozzles to spray out a gentle breeze in real time, which helps to remove dust from the space above the part of the mold to be inspected. By reducing the amount of dust in the space above the part of the mold to be inspected, the detection results of the optical scanner can be prevented from being affected by dust, thus helping to improve the accuracy of the detection results.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0018] Please see Figures 1-12 The present invention provides the following technical solution: Example 1: To address the problem that previous wear detection mechanisms for automotive interior parts molds had limited detection range, making it impossible to inspect larger molds, the following technical solution is provided: A wear detection mechanism for automotive interior parts molds includes a support frame 1 and a guide rod 2 mounted thereon.

The upper end of the motor frame 19 is provided with a hook-shaped frame, and the upper end bearing of the hook-shaped frame is connected to the outside of the push ring 16. A dual-axis servo motor 18 is mounted on the motor frame 19, and a worm gear 17 is keyed to the outer side of the upward output end of the dual-axis servo motor 18. The worm gear 17 is meshed with a worm wheel 15. A light-sensing scanner 6 is mounted on the downward output end of the dual-axis servo motor 18, and a suspension frame 33 is sleeved on the outer bearing of the upward output end of the dual-axis servo motor 18. The suspension frame 33 is located above the worm gear 17, and suspension rollers 34 are mounted on both sides of the upper end of the suspension frame 33. A rolling groove 28 is provided on the mounting frame 3, and the suspension rollers 34 are rolledly connected in the rolling groove 28. A strip-shaped sliding groove is provided on the mounting frame 3, and a wire conduit 35 is slidably connected in the strip-shaped sliding groove. The wire conduit 35 is used to install the wires that drive the dual-axis servo motor 18.

[0019] The worm gear 15 is connected to the reciprocating screw 7 via a trigger-driven mechanism. The trigger-driven mechanism includes a driven gear 8 connected to both ends of the reciprocating screw 7 via a one-way bearing. The trigger-driven mechanism also includes a pressure-bearing frame 27 that movably passes through the mounting frame 3. Two pressure-bearing frames 27 are provided, each corresponding to one end of the screw 14. The axis of the screw 14 is collinear with the axis of the pressure-bearing frame 27. Connecting pipes 25 are fixedly connected to the outer sides of both ends of the mounting frame 3. One end of a connecting rod 26 extends into the open end of the connecting pipe 25. The end of the connecting rod 26 extending into the connecting pipe 25 is seamlessly slidably connected to the inner side of the connecting pipe 25. The end of the connecting rod 26 outside the connecting pipe 25 is connected to the corresponding pressure-bearing frame 27. The axes of the pressure-bearing frame 27, the connecting rod 26, and the connecting pipe 25 are collinear. The inner side of the support frame 1 is fixedly connected... A support tube 23 is connected, and the support tubes 23 are evenly distributed on the side of the support frame 1 facing the opening end of the connecting tube 25. A support rod 24 is movably inserted into the opening end of the support tube 23, and the end of the support rod 24 extending into the support tube 23 is seamlessly slidably connected to the inner side of the support tube 23. The upper and lower sides of the driven gear 8 are meshed with a toothed plate frame 5, and the lower end of the toothed plate frame 5 is connected to the end of the support rod 24 outside the support tube 23. A T-shaped rod 21 is movably inserted through the lower end of the toothed plate frame 5, and the T-shaped rod 21 is fixedly connected to the inner side of the support frame 1. A return spring 22 is provided on the outer side of the T-shaped rod 21, connecting the lower end of the toothed plate frame 5 and the inner side of the support frame 1. The connecting tube 25 and the corresponding support tube 23 are connected through an air guide pipe 4, and the connecting tube 25, the corresponding support tube 23, and the corresponding air guide pipe 4 are filled with hydraulic oil.

[0020] according to Figures 1-8 as well as Figures 11-12 When in use, turn on the power of the dual-axis servo motor 18 and place the automotive interior part mold to be inspected under the light-sensing scanner 6. Start the dual-axis servo motor 18, so that both the upper and lower output ends of the dual-axis servo motor 18 rotate. When the lower output end of the dual-axis servo motor 18 rotates, the photosensitive scanner 6 connected to it rotates synchronously, thereby realizing full-angle detection of the mold. When the output end of the dual-axis servo motor 18 rotates upward, it drives the worm gear 17 to rotate synchronously. When the worm gear 17 rotates, it drives the worm wheel 15 that is meshed with it to rotate. When the worm gear 15 rotates, it can move on the fixed screw 14; As the worm gear 15 moves on the screw 14, the push ring 16 moves synchronously. At this time, the hook-shaped frame connected to the bearing causes the motor frame 19 to move synchronously with the push ring 16. In addition, the support rollers 32 and the suspension rollers 34 enable the motor frame 19 and the dual-axis servo motor 18 installed inside it to move stably. During the above process, one of the two push rings 16 will gradually approach the corresponding pressure frame 27, driving the pressure frame 27 to move synchronously with the corresponding connecting rod 26, thereby generating negative pressure in the corresponding connecting pipe 25, which in turn allows the hydraulic oil in the corresponding support pipe 23 to be transported from the air guide pipe 4 to the connecting pipe 25 that generates negative pressure. At this time, the support rod 24 connected to the support tube 23 will move away from it, thereby pushing the toothed plate frame 5 to move. During the process, the return spring 22 is stretched, and the movement of the toothed plate frame 5 will drive the driven gear 8 to rotate. With the cooperation of the one-way bearing, the reciprocating screw 7 can rotate, so that the photosensitive scanner 6 can not only move in the left and right directions through the screw 14, but also move back and forth automatically through the reciprocating screw 7 and the trigger drive mechanism. This greatly increases the detection range of the photosensitive scanner 6, so that it can detect larger automotive interior mold parts.

[0021] Example 2: To solve the problem that previous automotive interior parts mold wear detection mechanisms could not blow away dust from the space above the part of the mold to be tested, thus affecting the test results, the following technical solution is provided: Specifically, a follow-up jetting mechanism is installed on the mounting frame 3, and the follow-up jetting mechanism includes a limiting rod 30 set on the mounting frame 3, and the limiting rod 30 and the screw 14 are arranged parallel to each other.

[0022] The follow-up jet mechanism also includes a telescopic tube 9 provided on the outside of the limiting rod 30, and there are two telescopic tubes 9. The disc end of the extrusion frame 10 is provided on the outside of the limiting rod 30, and the disc end of the extrusion frame 10 is seamlessly slidably penetrated by the limiting rod 30. The two telescopic tubes 9 are connected to each other through the disc end on the extrusion frame 10, and the opposite ends of the two telescopic tubes 9 are respectively sealed and connected to the corresponding positions of the mounting frame 3. The gas collecting frame 11 is fixedly connected to the disc end on the extrusion frame 10, and the lower end of the gas collecting frame 11 is provided with two inclined jet holes 12. The mounting frame 3 is provided with a strip-shaped through groove on the side facing the disc end on the extrusion frame 10, and the strip-shaped through groove is connected to the lower part of the limiting groove 13. The lower part of the limiting groove 13 is slidably connected to the frame end on the extrusion frame 10, and the frame end on the extrusion frame 10 is penetrated by the downward output end bearing of the dual-axis servo motor 18. The mounting frame 3 is provided with a one-way air inlet 29 at the position corresponding to the telescopic tube 9, and a filter cover 20 is sleeved on the outside of the one-way air inlet 29. The disc end on the extrusion frame 10 passes through the telescopic tube 9 and the air collection frame 11 through the one-way air guide hole 31.

[0023] according to Figures 3-4 as well as Figures 9-10 When in use, because the light-sensing scanner 6 moves along the axis of the screw 14, the dual-axis servo motor 18 will move synchronously, which in turn causes the extrusion frame 10 through which the output shaft bearing of the dual-axis servo motor 18 passes to move synchronously as well. When the extrusion frame 10 moves, it will extrude one of the two telescopic tubes 9 and stretch the other telescopic tube 9. The internal air pressure of the extrusive tube 9 will gradually increase due to the extrusion. In order to balance the internal air pressure, the gas in the extrusive tube 9 will enter the gas collection frame 11 through the one-way air guide hole 31 and be ejected through the air jet hole 12. Because the speed of the photosensitive scanner 6 moving along the axis of the screw 14 is low, the speed of the gas ejected from the air jet hole 12 is low, so that the dust above the part to be tested on the mold can be gently blown away. This not only avoids the dust from affecting the detection results of the photosensitive scanner 6, but also avoids the gas ejected from the air jet hole 12 from being too fast and affecting the detection results of the photosensitive scanner 6. The internal air pressure of the stretched telescopic tube 9 decreases. In order to balance the internal air pressure, external air enters the stretched telescopic tube 9 through the one-way air inlet 29 after passing through the filter cover 20. In the above process, an annular channel is provided inside the disc end of the extrusion frame 10. The annular channel is connected to the gas collection frame 11 and is connected to the telescopic pipe 9 through the one-way air guide hole 31.

[0024] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0025] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
