Description

Technical Field

[0001] The invention relates to the field of die-casting dies, in particular to an automatic material-taking die-casting die for automobile parts. Background Art

[0002] After the die-casting mold processes the workpiece into shape, the workpiece needs to be ejected from the mold through the ejection system, and then the workpiece is removed from the mold through the material removal operation. This material removal process can be done manually or automatically. Due to the high temperature inside the die-casting mold, manual material removal poses a great safety hazard.

[0003] To this end, Chinese patent CN118558985B discloses a die-casting mold for automobile parts that can eject finished parts, which effectively improves the safety of material removal. When the die-removing tooth plate removes the automobile parts from the mold, it will drive the automobile parts to pass between the water spray seat and the L-shaped water spray plate, and the cooling water sprayed by the water spray seat and the L-shaped water spray plate will be used to cool the automobile parts to avoid burns when taking and placing the automobile parts, thereby further improving the safety of material removal.

[0024] The present invention realizes the function of cooling the workpiece 4 during the material taking process through the frame 1, the material taking device 2 and the cooling device 3. The workpiece 4 is immersed and cooled by high-temperature oil while the material is automatically taken. The heat on the workpiece 4 is transferred to the oil by using the heat transfer performance of the oil, and the cooling speed of the workpiece 4 is controlled to a certain extent, avoiding deformation or cracking caused by too fast or too slow cooling. It has the advantages of stable cooling performance and avoiding oxidation corrosion, and solves the problem that the traditional equipment cools during the automatic material taking process and affects the grasping stability of the workpiece 4. The linear drive component 13 includes a linear drive and a guide rod. The movable mold 12 is slidably matched with the guide rod. The linear drive is preferably a hydraulic cylinder, and the hydraulic cylinder controls the movable mold 12 to move for die casting. After the processing is completed, the movable mold 12 is separated from the fixed mold 11 by the linear drive, and then the workpiece 4 is ejected by the ejection component 111 on the fixed mold 11. After the workpiece 4 is ejected, it is taken by the material taking hand 22, and then the first lifting component 23 controls the mounting plate 21 to move downward, and the workpiece 4 is removed from the cavity from the material taking channel. In this process, the second lifting assembly 31 controls the mounting seat 211 to move downward, and the mounting seat 211 drives the material picking hand 22 and the workpiece 4 to move downward, and then the workpiece 4 is moved into the cooling box 32, and the workpiece 4 is cooled by immersion in the high-temperature oil in the cooling box 32. In the cooling process, the first lifting assembly 23 completely moves the mounting plate 21 to the bottom of the frame 1. When the workpiece 4 is cooled to below the specified temperature, the mounting seat 211, the material picking hand 22 and the workpiece 4 are removed from the cooling box 32 by the second lifting assembly 31, and then the workpiece 4 is transported. Compared with the traditional material picking mechanism, the present invention can evenly immerse and cool the workpiece 4 after picking.

[0025] Reference Figure 1 , Figure 3 and Figure 4 : The cooling device 3 includes a buffer component 33 and a connecting component 34; the second lifting component 31 is connected to the mounting seat 211 through the buffer component 33 and the connecting component 34; in the working state, when the connecting component 34 connects the second lifting component 31 and the mounting seat 211, the buffer component 33 is in a compressed state.

[0026] The present invention realizes the function of controlling the connection between the second lifting assembly 31 and the mounting seat 211 through the buffer assembly 33 and the connecting assembly 34. After the picker 22 is connected to the workpiece 4, the overall gravity of the mounting seat 211 increases, and then the resistance of the buffer assembly 33 is overcome under the action of gravity and moves downward, compressing the buffer assembly 33. As the buffer assembly 33 is compressed, the connecting assembly 34 connects the second lifting assembly 31 and the mounting seat 211, and then the second lifting assembly 31 controls the mounting seat 211 to move downward, moving the workpiece 4 into the cooling box 32, and uniformly cooling the workpiece 4. After the cooling is completed, the second lifting assembly 31 controls the mounting seat 211 to move upward, and the workpiece 4 is removed from the cooling box 32, and then the cooled workpiece 4 is moved to the designated unloading location through other tools or equipment.

[0027] Reference Figures 2 to 6 : The second lifting assembly 31 includes a guide rail 311, a second rotation driver 312 and a screw 313; the guide rail 311 is arranged on the mounting plate 21, and the mounting seat 211 is slidably matched with the guide rail 311; the second rotation driver 312 is arranged on the cooling box 32; the screw 313 is rotatably arranged on the mounting plate 21, and the mounting seat 211 is threadedly connected to the screw 313 through the connecting assembly 34, and the second rotation driver 312 is used to drive the screw 313 to rotate.

[0028] The present invention realizes the function of driving the mounting seat 211 to rise and fall along the guide rail 311 through the guide rail 311, the second rotary driver 312 and the screw 313. The frame 1 is provided with a controller for human-machine interaction, the second rotary driver 312 is preferably a servo motor, and the second rotary driver 312 is electrically connected to the controller, and a pulley 314 is sleeved on the driving end of the screw 313 and the second rotary driver 312, and the two pulleys 314 are connected by a transmission belt 315. The cooling box 32 is connected to the mounting plate 21. After the workpiece 4 is die-cast, the mold opening operation is performed by driving the linear drive component 13, and then the first lifting component 23 controls the mounting plate 21 to move upward. After the material picking arm 22 is connected to the workpiece 4, the mounting seat 211 moves downward under the action of gravity to compress the buffer component 33, and after the mounting seat 211 contacts the connecting component 34, the connecting component 34 connects the second lifting component 31 and the mounting seat 211, and then the controller sends a signal to the second rotary driver 312, and the second rotary driver 312 drives the screw 313 to rotate through the pulley 314 and the transmission belt 315, and the screw 313 drives the mounting seat 211 to move along the guide rail 311 through the connecting component 34, and moves the workpiece 4 to the cooling box 32 through the mounting seat 211 and the material picking arm 22 to cool the workpiece 4.

[0029] Reference Figure 3 , Figure 4 and Figure 7 : The buffer assembly 33 includes a lifting seat 331, a first elastic member 332 and a damping rod 333; the lifting seat 331 is slidably installed on the guide rail 311, and the lifting seat 331 is threadedly connected to the screw 313; the two ends of the first elastic member 332 are respectively connected to the two ends of the damping rod 333, the damping rod 333 is set on the lifting seat 331, and the piston rod of the damping rod 333 is transmission-connected to the mounting seat 211.

[0030] The present invention realizes the function of providing a buffering effect on the movement of the mounting seat 211 through the lifting seat 331, the first elastic member 332 and the damping rod 333, and cooperates with the deformation ability of the first elastic member 332 and the damping rod 333 to achieve the effect of detecting whether the material picking hand 22 adsorbs the workpiece 4, and after adsorbing the workpiece 4, the second lifting assembly 31 and the mounting seat 211 are connected through the connecting assembly 34, and the lifting and lowering of the mounting seat 211 are automatically controlled to achieve the effect of automatically cooling after grabbing the workpiece 4. After the material picking hand 22 grabs the workpiece 4, the gravity of the workpiece 4 acts on the mounting seat 211, and the force is transmitted to the first elastic member 332 and the damping rod 333 through the mounting seat 211, so that the first elastic member 332 contracts, and the setting of the damping rod 333 avoids the mounting seat 211 from being lifted and lowered multiple times with a small amplitude, thereby improving the stability of grabbing the workpiece 4. As the first elastic member 332 contracts, after the mounting seat 211 contacts the lifting seat 331, the connecting assembly 34 connects the lifting seat 331 and the mounting seat 211, and then the second rotary driver 312 drives the screw 313 to rotate to drive the mounting seat 211 and the lifting seat 331 to move downward. After the workpiece 4 is cooled, before the material is taken again, after the material taking hand 22 is separated from the workpiece 4, the first elastic member 332 is reset under the action of elastic force, and the screw 313 is driven to rotate by the second rotary driver 312, and the screw 313 drives the lifting seat 331 to move upward, and the lifting seat 331 transmits thrust through the first elastic member 332 and the damping rod 333 to push the mounting seat 211 to reset.

[0031] Reference Figure 3 , Figure 4 , Figure 7 and Figure 8 : The connecting assembly 34 includes a movable sleeve 341 and a round table 342; a bracket 212 is provided on the mounting seat 211, the movable sleeve 341 is rotatably connected to the bracket 212, and the movable sleeve 341 is threadedly connected to the screw 313; the round table 342 is arranged on the lifting seat 331, and when the movable sleeve 341 abuts against the round table 342, the round table 342 limits the rotation of the movable sleeve 341.

[0032] The present invention realizes the function of threading the mounting seat 211 and the screw rod 313 through the movable sleeve 341 and the round table 342. The piston rod of the damping rod 333 is connected to the bracket 212. When the second rotary driver 312 is used to drive the screw rod 313 to rotate to control the downward movement of the mounting seat 211, if the mounting seat 211 is directly pulled by the lifting seat 331 and the first elastic member 332, the mounting seat 211 will fluctuate up and down during the movement, causing the workpiece 4 to be unstable during the movement. For this reason, a connecting assembly 34 is provided to connect the mounting seat 211 and the lifting seat 331, so that the mounting seat 211 and the lifting seat 331 can move downward synchronously to maintain the stability of the movement of the workpiece 4. When the material picking hand 22 removes the workpiece 4, the first elastic member 332 is compressed, so that the mounting seat 211 drives the movable sleeve 341 to move toward the lifting seat 331, so that the movable sleeve 341 abuts against the round table 342, and then the movable sleeve 341 is restricted from rotating by the round table 342. After the movable sleeve 341 cannot rotate, the screw rod 313 drives the movable sleeve 341 and the lifting seat 331 to move downward when rotating, so as to avoid instability of the mounting seat 211 during movement.

[0033] Reference Figure 3 , Figure 4 , Figure 7 and Figure 8 The movable sleeve 341 is provided with a groove 3411 which cooperates with the docking block 3421. When the docking block 3421 is plugged into the groove 3411, the movable sleeve 341 is restricted from rotating.

[0034] The present invention realizes the function of limiting the rotation of the movable sleeve 341 when the movable sleeve 341 abuts against the docking block 3421 through the docking block 3421 and the groove 3411. When the movable sleeve 341 contacts the round table 342 on the lifting seat 331, if the docking block 3421 on the round table 342 is not aligned with the groove 3411 of the movable sleeve 341, the second rotary driver 312 drives the screw rod 313 to rotate, and the screw rod 313 drives the lifting seat 331 threadedly connected thereto to move. Since the movement of the mounting seat 211 is subject to resistance, the movable sleeve 341 and the screw rod 313 will be hindered by the resistance when they rotate relative to each other, so the screw rod 313 will drive the movable sleeve 341 to rotate when rotating. 1 synchronously rotates, and as the movable sleeve 341 rotates, when the groove 3411 on the movable sleeve 341 is aligned with the docking block 3421, the mounting seat 211 is further moved downward relative to the lifting seat 331 under the action of gravity, so that the docking block 3421 is aligned with the groove 3411, and the rotation of the movable sleeve 341 is blocked by the docking block 3421, so that the movable sleeve 341 can rotate relative to the screw rod 313, and then the movable sleeve 341 and the lifting seat 331 are driven to rise and fall synchronously through the rotation of the screw rod 313. In addition, there are multiple grooves 3411 and docking blocks 3421, and the multiple grooves 3411 and docking blocks 3421 are distributed in a circular array about the axis of the screw rod 313, and the more the number of grooves 3411 and docking blocks 3421, the higher the docking efficiency of the movable sleeve 341 and the round table 342.

[0035] Reference Figure 1-Figure 3 The cooling box 32 is provided with a liquid inlet pipe 321 and a liquid outlet pipe 322.

[0036] The present invention realizes the function of facilitating the operator to control the oil temperature in the cooling box 32 by arranging the liquid inlet pipe 321 and the liquid outlet pipe 322 on the cooling box 32. The liquid inlet pipe 321 and the liquid outlet pipe 322 are connected to the oil tank through the pipeline and the pump body. During the working process, the circulation supply of the oil system is completed through the transmission of the liquid inlet pipe 321 and the liquid outlet pipe 322, thereby stabilizing the temperature of the oil in the cooling box, stabilizing the cooling efficiency of the oil on the workpiece 4 as much as possible, and preventing the oil in the cooling box from heating up after a long period of work and affecting the cooling efficiency.

[0037] Reference Figure 1-Figure 3 : A temperature sensor 323 for detecting the oil temperature is provided on the liquid outlet pipe 322.

[0038] The present invention realizes the function of real-time detection of the temperature of the oil discharged from the cooling box 32 through the temperature sensor 323. The temperature sensor 323 is electrically connected to the controller; during the cooling process, the oil needs to absorb the heat on the workpiece 4, thereby increasing the temperature difference between the oil discharged from the outlet pipe 322 and the oil input into the inlet pipe 321. The input oil temperature is at the same temperature under the control of the operator, and the temperature of the discharged oil will fluctuate. As the workpiece 4 cools down, the heat absorbed by the oil decreases, and the temperature difference between the discharged oil and the input oil decreases. The temperature difference is calculated and analyzed through the signal fed back by the temperature sensor 323. When the temperature difference is less than the threshold, the cooling is stopped, and the workpiece 4 is controlled to move up through the second lifting component 31 to transfer the workpiece 4.
