Description

Technical Field

[0001] This utility model relates to the field of mold manufacturing technology, and in particular to a special mold for machining toothed parts without collapsing corners. Background Technology

[0002] Toothed parts are key components used in mechanical transmission and power transmission. The core feature of these parts is the regularly arranged tooth-like structure on their surface. As the core component of mechanical transmission, the precision of the teeth in these parts directly determines the operating efficiency and stability of the equipment. To avoid weakening the load-bearing capacity and meshing performance of these parts, special molds for machining toothed parts without collapsing corners have been developed.

[0003] The special mold for machining toothed parts without corner collapse is a special tooling developed to address the problem of corner collapse at the tooth root and tooth tip during the machining of toothed parts. Its core design lies in the precise fit between the mold cavity and the toothed part, which can form uniform and stable support for the weak parts of the part's teeth during the machining process, avoiding corner collapse caused by misalignment.

[0004] Although special molds for machining toothed parts without corner collapse reduce friction damage to the parts and extend their service life, the mold cavity needs to be designed to fit the parts perfectly to ensure the sharpness of the edges and corners of the toothed parts. This results in dead corners. Metal debris left over from the machining process accumulates in these dead corners over a long period, which will lead to increased wear on the cavity and even affect the dimensional accuracy of the parts. The current solution is to clean them manually. After disassembling the mold, brushes, tweezers, and high-pressure air guns are used to manually clean the debris and lubricant left over from the dead corners. However, manual cleaning requires frequent mold disassembly, resulting in long downtime and high maintenance costs. Furthermore, the cleaning process depends on the operator's experience, and improper operation can damage the mold surface. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figure 1 , Figure 3 and Figure 4 An embodiment of this utility model provides: a special mold for processing toothed parts without corner collapse, including a base plate 1 and a top plate 2. The top of the base plate 1 is provided with an impurity collection mechanism 3, which is used to collect impurities in the corners. The top of the top plate 2 is fixedly connected with a hydraulic cylinder 4. The top of the base plate 1 is provided with an unloading mechanism 5, which is used to quickly and safely remove and store the completed parts. The top of the top plate 2 is provided with an oil supply mechanism 6, which is used to provide power to the hydraulic cylinder 4. The bottom of the hydraulic cylinder 4 is fixedly connected with a telescopic rod 7. The hydraulic cylinder 4 and the telescopic rod 7 are used to make the two molds produce toothed parts. The impurity collection mechanism 3 includes a vacuum pump 301, which provides suction for impurity collection. The front end of the vacuum pump 301 is fixedly connected to the rear right end of the base plate 1. A storage box 302 is fixedly connected to the rear side of the base plate 1. The storage box 302 is used to collect the collected impurities. A filter screen 303 is fixedly connected to the top of the inner wall of the storage box 302. The filter screen 303 is used to filter the impurities, ensuring that the impurities remain in the storage box 302 and prevent them from entering the vacuum pump 301. A suction pipe 304 is connected to the top left side of the storage box 302. The outer wall of the suction pipe 304 has multiple suction holes 305. The suction pipe 304 and the suction holes 305 are used to suck up and transport impurities to the storage box 302. The top end of the vacuum pump 301 is connected to... An exhaust pipe 306 is used to discharge exhaust gas and guide the discharged gas. A fixing block 307 is fixedly connected to the middle of the front side of the base plate 1. The fixing block 307 is used to limit the position of the air blowing box 308. The top of the fixing block 307 is rotatably connected to the air blowing box 308. The air blowing box 308 is used to blow the discharged gas toward the working area so that impurities in the dead corner are blown out. An electric push rod 309 is fixedly connected to the top front side of the base plate 1. A rotator 310 is fixedly connected to the top of the electric push rod 309. The electric push rod 309 and the rotator 310 are used to control the direction of gas blowing. A pressure stabilizing and conveying assembly 311 is provided on the rear side of the base plate 1.

The pressure stabilizing and conveying assembly 311 includes a gas tank 3111, which stores compressed gas. The front end of the gas tank 3111 is fixedly connected to the rear right end of the base plate 1. The rear end of the gas tank 3111 is provided with a connecting pipe 3112, which is used to convey the gas to the vacuum pump 301. Specifically, after the device starts up, impurities begin to be generated. The vacuum pump 301 is then activated, and a stable air pressure is supplied to the vacuum pump 301 through the gas tank 3111 and connecting pipe 3112. This ensures that the negative pressure generated by the vacuum pump 301 is continuous and stable. Then, through the suction pipe 304, multiple suction holes 305 on the outer wall generate suction in dead corners and narrow gaps within the device, thereby sucking in the metal shavings and lubricant mixture remaining from processing. This mixture is then transported to the storage box 302 via the suction pipe 304. Simultaneously, the filter screen 303 inside the storage box 302 intercepts and filters the impurities, keeping them within the storage box 302 to prevent contamination. To prevent damage to the vacuum pump 301, the gas generated by the vacuum pump 301 is filtered and discharged through the exhaust pipe 306, entering the blowing box 308 rotatably connected to the top of the fixed block 307. At the same time, the electric push rod 309 extends and retracts, and works with the rotator 310 to adjust the angle of the blowing box 308, directing the exhaust gas towards the dead corner area. The airflow impact removes impurities, which are then efficiently sucked into the suction hole 305 of the suction pipe 304. The entire process does not require disassembling the mold and allows the collection and cleaning of impurities in the dead corner to be carried out simultaneously, reducing the cost of manual cleaning, minimizing downtime, and extending the service life of the device.

[0020] Reference Figure 2 , Figure 3 and Figure 5 The unloading mechanism 5 includes two fixed platforms 501. The fixed platforms 501 stabilize the power source. A servo motor 502 is fixedly connected to the top front side of the front fixed platform 501. The servo motor 502 serves as the power source to move the position of the part.

The parts are oriented downwards under the action of gravity, which facilitates the placement of the parts. They can be rotated around the rotating shaft 503 to adjust and store the parts. An electromagnetic block 506 is fixedly connected to the bottom of the connecting block 505. The electromagnetic block 506 is used to fix the parts. A monitor 507 is fixedly connected to the right side of the rear fixed platform 501. The monitor 507 is used to monitor the state of the mold. A material receiving assembly 508 is provided on the outer wall of the base plate 1. The material receiving assembly 508 is used to store the parts. A placement assembly 509 is provided on the outer wall of the base plate 1. The placement assembly 509 is used to fix the storage box 5081 to the left side of the base plate 1. The receiving assembly 508 includes a storage box 5081, which is used to store parts. The right side of the storage box 5081 is slidably connected to the left side of the base plate 1. Multiple casters 5082 are fixedly connected to the bottom of the storage box 5081. The casters 5082 facilitate the movement of the storage box 5081. The placement assembly 509 includes a slide rod 5091, which is slidably connected to the left side of the base plate 1. A groove 5092 is provided on the left side of the base plate 1. The sliding connection between the slide rod 5091 and the groove 5092 facilitates the fixing and replacement of the storage box 5081. Specifically, after processing is completed, the monitor 507 detects the mold opening, causing the servo motor 502 to operate, driving the rotating shaft 503 to rotate between the two fixed platforms 501. The rotating bar 504 rotates with the shaft. When the rotating bar 504 rotates to the mold position, the electromagnetic block 506 at the bottom of the connecting block 505 is energized to generate magnetic force, attracting the formed toothed parts. Subsequently, the rotating shaft 503 continues to rotate, and the rotating bar 504 drives the parts away from the cavity. The connecting block 505 rotates with the rotating bar 504, causing the parts to hang down naturally. When it rotates above the receiving assembly 508, the electromagnetic block 506 is de-energized, and the parts fall into the storage box 5081 under the action of gravity. When the storage box 5081 needs to be replaced, the sliding connection between the slide rod 5091 and the slide groove 5092 allows the storage box 5081 to be detached from the fixed position. The universal wheel 5082 pushes the storage box 5081 to move and replace, realizing safe, fast and efficient unloading and storage of parts.

[0021] Reference Figure 1 , Figure 2 and Figure 3 The oil delivery mechanism 6 includes an oil tank 601 for storing hydraulic oil. The bottom end of the oil tank 601 is fixedly connected to the top of the top plate 2. A hydraulic pump 602 is fixedly connected to the top of the top plate 2. The hydraulic pump 602 is used to draw hydraulic oil and deliver it to the hydraulic cylinder 4. An upper mold 8 is fixedly connected to the bottom end of the telescopic rod 7. A lower mold 9 is fixedly connected to the top of the base plate 1. The upper mold 8 and the lower mold 9 are used to process toothed parts. A rubber pad 10 is fixedly connected to the bottom of the base plate 1 for shock absorption. An anti-slip strip 11 is fixedly connected to the bottom of the rubber pad 10 for increasing friction. Specifically, after the device is started, the hydraulic oil stored in the oil tank 601 powers the hydraulic cylinder 4. The hydraulic pump 602 operates after being powered on, drawing hydraulic oil from the oil tank 601 and delivering it to the hydraulic cylinder 4 through pipelines. After the hydraulic oil enters the hydraulic cylinder 4, it pushes the telescopic rod 7 to extend downwards, causing the upper mold 8 connected to the top to move down synchronously and precisely fit with the lower mold 9 on the top of the base plate 1. During the mold closing process, the toothed parts are formed and processed. During the processing, the rubber pad 10 at the bottom of the base plate 1 absorbs the vibration generated by the equipment through its own elastic deformation, reducing the impact on the processing accuracy. The anti-slip strip 11 at the bottom of the rubber pad 10 increases the friction with the ground, preventing the equipment from shifting. After processing is completed, the hydraulic pump 602 is reversed, causing the hydraulic oil in the hydraulic cylinder 4 to be drawn back into the oil tank 601. The telescopic rod 7 then drives the upper mold 8 to reset and rise, completing one cycle.

[0022] Working principle: After the vacuum pump 301 is started, the gas tank 3111 provides a stable air pressure to the vacuum pump 301 through the connecting pipe 3112, ensuring that the vacuum pump 301 generates a continuous negative pressure. The suction pipe 304, with the help of the suction hole 305 opened on the outer wall, forms a suction force on the dead corners and narrow gaps in the device, sucking in the metal scraps and lubricant mixture impurities, which are then transported to the storage box 302 through the pipeline. The filter screen 303 can intercept impurities to prevent them from damaging the vacuum pump 301. At the same time, the gas discharged by the vacuum pump 301 is introduced into the blowing box 308 through the exhaust pipe 306. The electric push rod 309 and the rotator 310 can adjust the orientation of the blowing box 308, directing the airflow to the dead corners, loosening the residual impurities, and improving the adsorption efficiency of the suction hole 305. The whole process does not require disassembling the mold, which can realize the real-time cleaning and collection of impurities, reduce labor costs and downtime, and protect the device and reduce wear. Furthermore, the status of the mold is monitored in real time by the monitor 507. After the mold is opened, the servo motor 502 is started, so that the power is transmitted to the rotating bar 504 through the rotating shaft 503. The rotating bar 504 rotates around the rotating shaft 503 between the fixed table 501. When the rotating bar 504 drives the connecting block 505 to move to the mold position, the electromagnetic block 506 is energized to generate magnetic force, which accurately attracts the formed toothed parts. The rotating shaft 503 continues to rotate. Through the rotational connection between the rotating bar 504 and the connecting block 505, the parts naturally droop with the rotation, avoiding collision damage during transportation. When the parts are transported to the receiving component 508, the electromagnetic block 506 is de-energized and the parts are released. The parts fall into the storage box 5081 by gravity. When changing the storage box 5081, the sliding rod 5091 is used to move along the slide groove 5092 to get out of the position restriction. The caster wheel 5082 is used to move and change the box conveniently, realizing safe and efficient unloading and storage.
