A turbocharger volute casting device

Abstract

The present invention relates to the field of turbocharger casting technology, and in particular to a turbocharger volute casting device, comprising a casting mold one, which is used for forming a turbocharger volute, and a casting mold two, which is arranged at the front of the casting mold one. When the casting mold one and the casting mold two are molded together, the enclosure frame at the back of the casting mold two is inserted into the enclosure groove at the front of the casting mold one. The enclosure frame and the enclosure groove frame a cavity composed of the mold groove and the module. If the mold cavity is slightly deformed during long-term use, resulting in leakage of injected metal liquid, the enclosure frame and the enclosure groove can prevent the overflow of the metal liquid, so that the overflowed metal liquid is confined to the range framed by the enclosure frame and the enclosure groove. The overflowed metal liquid will form burrs on the outside of the volute after cooling. The enclosure frame and the enclosure groove prevent the burrs on the outside of the volute from being too large, which affects the subsequent burr removal, by limiting the leaked metal liquid.

Description

Technical Field

[0001] The invention relates to the technical field of turbocharger casting, in particular to a turbocharger volute casting device. Background Art

[0002] The turbocharger volute casting device is mainly used to produce the volute part of the turbocharger. The mold required for casting is one of the components of the casting device. The molten metal liquid is injected into the cavity in the mold, and the cavity is used to shape the volute. After cooling, the formed volute can be taken out.

[0003] The prior art also proposes some solutions. For example, a patent application with authorization announcement number CN218109311U discloses a casting mold for a high-precision turbocharger compression shell, including a rear mold with mold feet on both sides of the lower end of the rear mold. The application facilitates the docking of the front mold and the rear mold through a docking assembly, making the front mold and the rear mold fit more closely.

[0004] Although the above-mentioned technical solution can make the mold more accurately fit when used, the mold is prone to slight deformation and gaps in the mold cavity due to heat load and temperature fluctuations during the long-term injection of high-temperature molten metal. These gaps will cause the molten metal to flow in and form burrs around the volute. The burrs produced by smaller gaps are thinner and can be removed by deburring equipment, but larger gaps will not only make the burrs thicker and larger, increasing the difficulty of removal, but may also lead to insufficient amount of molten metal in the mold cavity, affecting the molding quality of the volute. Summary of the invention

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the problem in the prior art that the mold cavity is deformed and metal liquid overflows due to long-term use of the mold.

[0016] The above technical solution of the present invention has the following advantages compared with the prior art:

[0017] 1. A turbocharger volute casting device described in the present invention, when a casting mold 1 and a casting mold 2 are molded together, the enclosing frame on the back of the casting mold 2 is inserted into the enclosing groove on the front of the casting mold 1, and the enclosing frame and the enclosing groove frame the cavity composed of the mold groove and the module. If the mold cavity is slightly deformed during long-term use, resulting in leakage of the injected metal liquid, the enclosing frame and the enclosing groove can prevent the metal liquid from overflowing, so that the overflowed metal liquid is confined to the range framed by the enclosing frame and the enclosing groove. The overflowed metal liquid will form burrs on the outside of the volute after cooling. The enclosing frame and the enclosing groove prevent the burrs on the outside of the volute from being too large, which affects the subsequent burr removal, by limiting the leaked metal liquid.

[0018] 2. The turbocharger volute casting device described in the present invention limits the overflowed molten metal by means of an enclosure frame and an enclosure groove. The overflowed molten metal flows downward under the action of gravity and flows into an overflow collecting box through the second and first liquid guide holes. The overflow collecting box collects the overflowed molten metal and detects the weight of the collected molten metal by means of gravity sensors at the four corners of the bottom of the overflow collecting box. The weight data of each overflowed molten metal is transmitted to a terminal device. When the gravity sensor detects the weight data of the overflowed molten metal, it is known that the mold is deformed. The deformation degree of the mold is determined based on the weight data of the overflowed molten metal. The overflow of molten metal caused by a slight deformation of the mold cavity will form burrs around the volute. If the amount of overflowed molten metal increases due to the deformation of the mold cavity, the mold needs to be repaired. The lifting gear is driven by a motor to rotate. The surrounding frame has only 1 / 4 of the teeth. When the teeth of the lifting gear mesh with the tooth plate, the lifting gear drives the tooth plate to move up, and the tooth plate drives the movable block and the knocking head to move up. The upward movable block squeezes spring one, and the upward knocking head moves to the top of the built-in groove. At the moment when the teeth of the lifting gear are separated from the teeth on the tooth plate, the spring pushes the movable block down to drive the knocking head to knock downward on the outer wall of the enclosure frame. The tooth plate returns to its initial position under the action of the movable block. This can be repeated by using the knocking head to continuously knock on the side wall of the enclosure frame to generate vibration force, so as to speed up the overflowed metal liquid to flow down and flow into the overflow collection box through the liquid guide hole one and the liquid guide hole two, so that the gravity sensor at the bottom of the overflow collection box can quickly detect the amount of overflowed metal liquid. At the same time, the vibration force generated by the knocking can also accelerate the diffusion speed of the metal liquid in the chamber composed of the mold groove and the module, so that the metal liquid can quickly form a vortex shell in the chamber.

[0031] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0032] Reference Figures 1 to 10As shown, a turbocharger volute casting device of the present invention comprises a casting mold 1 for molding a turbocharger volute; a casting mold 2, which is arranged at the front of the casting mold 1, and the casting mold 1 and the casting mold 2 are connected to form a whole mold; a hydraulic telescopic rod 3, which is installed at the back of the casting mold 1, and is used to push and pull the casting mold 1 to move and close or open the mold with the casting mold 2; a demolding component 4, which is installed at the front of the casting mold 2, and is used to demold the molded volute in the casting mold 2; a mold groove 5, which is opened at the back of the casting mold 2 ; Module 6, fixed to the front of the casting mold 1, and the chamber formed with the mold groove 5 is used for molding the volute; the enclosure component 7 is arranged around the mold groove 5 to block the overflowing metal liquid, and the position of the enclosure component 7 corresponds to the module 6; the overflow collection component 8 is arranged at the bottom of the module 6 to collect and detect the amount of overflowing metal liquid; the knocking component 9 is arranged around the module 6 to knock the enclosure component 7 to generate vibration force to accelerate the metal liquid to flow into the overflow collection component 8 for collection and detection; the touch component 10 is arranged in the overflow collection component 8;

[0033] The casting mold 1 and the casting mold 2 are installed at the desired positions, and the casting mold 1 is pushed toward the position of the casting mold 2 by the hydraulic telescopic rod 3 to move and close the mold, and the module 6 at the front of the casting mold 1 is moved into the mold groove 5 at the back of the casting mold 2. The mold groove 5 and the module 6 form a casting chamber required for casting the volute, and the molten metal liquid is injected into the casting chamber required for casting the volute composed of the mold groove 5 and the module 6 to form the casting chamber, and after cooling and forming, the hydraulic telescopic rod 3 is started to drive the casting mold 1 to move backward to open the mold, and the demoulding component 4 is cooperated to push the volute formed in the mold groove 5 to demould;

[0034] When the casting mold 1 and the casting mold 2 are molded together, the enclosure assembly 7 frames the cavity composed of the mold groove 5 and the module 6. If the mold cavity is slightly deformed during long-term use, resulting in leakage of the injected metal liquid, the enclosure assembly 7 can prevent the metal liquid from overflowing, so that the overflowed metal liquid is confined to the range framed by the enclosure assembly 7. After cooling, the overflowed metal liquid will form burrs on the outside of the volute. The enclosure assembly 7 prevents the burrs on the outside of the volute from being too large by limiting the leaked metal liquid, which affects the subsequent burr removal.

[0035] The overflowed metal liquid flows into the overflow collection component 8 for collection. The overflow collection component 8 detects the weight of the collected metal liquid, and obtains the amount of each overflow according to the weight of the metal liquid overflowed each time. If the amount of the overflowed metal liquid exceeds the preset value, the overflow collection component 8 moves down to control the touch component 10 to start, and warns the staff that the overflowed metal liquid exceeds the preset value, so that the staff can repair the mold. When the casting mold 1 and the casting mold 2 are opened, the overflow collection component 8 discharges the collected metal liquid. When the casting mold 1 and the casting mold 2 are closed, the overflow collection component 8 is reset to collect the metal liquid.

[0036] The vibration component 9 is used to knock the enclosure component 7 to generate vibration force, thereby accelerating the speed at which the overflowed metal liquid flows into the overflow collection component 8. At the same time, the vibration force generated by the knocking can also accelerate the diffusion speed of the metal liquid in the cavity formed by the mold groove 5 and the module 6.

[0037] Reference Figures 1 to 5 As shown, the enclosure assembly 7 includes: an enclosure frame 71, which is fixed to the back of the casting mold 2, and the enclosure frame 71 is located around the mold groove 5; an enclosure groove 72, which is opened at the front of the casting mold 1, and is located around the module 6. The enclosure groove 72 matches the size of the enclosure frame 71 and the position is exactly corresponding, and the enclosure frame 71 can be inserted into the enclosure groove 72;

[0038] When the casting mold 1 and the casting mold 2 are closed, the enclosing frame 71 on the back of the casting mold 2 is inserted into the enclosing groove 72 on the front of the casting mold 1. The enclosing frame 71 and the enclosing groove 72 frame the cavity composed of the mold groove 5 and the module 6. If the mold cavity is slightly deformed during long-term use, resulting in leakage of the injected metal liquid, the enclosing frame 71 and the enclosing groove 72 can prevent the overflow of the metal liquid, so that the overflowed metal liquid is confined to the range framed by the enclosing frame 71 and the enclosing groove 72. After cooling, the overflowed metal liquid will form burrs on the outside of the volute casing. The enclosing frame 71 and the enclosing groove 72 prevent the burrs on the outside of the volute casing from being too large, which affects the subsequent burr removal, by limiting the leaked metal liquid.

[0039] Reference Figures 1 to 7As shown, the overflow collection assembly 8 includes: a gear rod 81, fixed to the back of the casting mold 2, located on both sides below the enclosure frame 71; a groove 82, opened at the front of the casting mold 1, located below the module 6, and the groove 82 is designed in an arc shape; a slot 83, opened on both sides of the bottom of the groove 82, corresponding to the position of the gear rod 81, and the gear rod 81 is placed in the slot 83; the overflow collection assembly 8 also includes: a support frame 84, rotatably set in the groove 82; an overflow collection box 85, installed in the support frame 84, for collecting overflowed metal liquid; a flip gear 86, set in the slot 83, fixed on both sides of the support frame 84 The driving gear 87 is arranged at the bottom of the flipping gear 86, located at the top of the gear rod 81, meshed with the flipping gear 86, and rotatably arranged in the slot 83; the overflow collection assembly 8 also includes: a liquid guide hole 88, which is arranged at the bottom of the enclosure groove 72, located above the overflow collection box 85, and facing the opening at the top of the overflow collection box 85; a liquid guide hole 89, which is arranged at the bottom of the enclosure frame 71, and corresponds to the position of the liquid guide hole 88; a gravity sensor 810, which is installed at the four corners of the bottom of the overflow collection box 85, and is used to detect the weight of the metal liquid collected in the overflow collection box 85;

[0040] After the mold is closed, the enclosure frame 71 is inserted into the enclosure groove 72. When the mold is deformed, the enclosure frame 71 and the enclosure groove 72 are no longer tightly engaged, and a gap appears between the enclosure frame 71 and the enclosure groove 72, causing the metal liquid to overflow. The overflowed metal liquid flows downward under the action of gravity, and the overflowed metal liquid flows into the overflow collection box 85 through the second liquid guide hole 89 and the first liquid guide hole 88. The overflow collection box 85 collects the overflowed metal liquid, and uses the gravity sensors 810 at the four corners of the bottom of the overflow collection box 85 to detect the weight of the collected metal liquid, and transmits the weight data of each overflowed metal liquid to the terminal device. When the gravity sensor 810 detects the weight data of the overflowed metal liquid, it can be known that the mold is deformed. According to the weight data of the overflowed metal liquid, the deformation degree of the mold is judged. The overflow of metal liquid caused by the slight deformation of the mold cavity will form burrs around the volute. The weight of the overflowed metal liquid is recorded in real time so that the staff can timely understand the data information of the overflowed metal liquid of the mold;

[0041] When the casting mold 1 and the casting mold 2 are opened, the casting mold 2 drives the gear rod 81 to gradually move out of the slot 83. When the toothless portion of the gear rod 81 is located at the bottom of the driving gear 87, the driving gear 87 is not driven to rotate.

[0042] When the toothed portion of the gear rod 81 meshes with the driving gear 87, the gear rod 81 drives the driving gear 87 to rotate, and the driving gear 87 drives the flipping gear 86 to flip the support frame 84 outward, and the support frame 84 drives the overflow collection box 85 to follow the flipping to pour out the collected metal liquid for the next inspection. It should be noted here that the toothless portion of the gear rod 81 first moves at the bottom of the driving gear 87 and does not drive it to rotate, ensuring that the support frame 84 and the overflow collection box 85 will tilt after the casting mold 1 and the casting mold 2 are opened, preventing the problem of interference caused by the support frame 84 and the overflow collection box 85 tilting at the moment of the casting mold 1 and the casting mold 2 being opened;

[0043] When the casting mold 1 and the casting mold 2 are molded together, the gear rod 81 gradually enters the slot 83, the toothed part of the gear rod 81 meshes with the driving gear 87 and drives the driving gear 87 to rotate in the opposite direction, and the driving gear 87 flips the support frame 84 in the opposite direction and flips it into the slot 83 through the flipping gear 86. After the toothless part of the gear rod 81 moves to the bottom of the driving gear 87, the casting mold 1 and the casting mold 2 are molded together, and the front wall of the casting mold 2 will abut against the support frame 84 and the overflow collection box 85 to place it under the liquid guide hole 1 88 to collect the metal liquid. It should be noted here that the casting mold 1 and the casting mold 2 are molded together. After the mold 2 is opened, the gear rod 81 does not move out from the bottom of the driving gear 87 and remains in meshing with the driving gear 87. The purpose is to ensure that the overflow collection box 85 is in a downward and inclined pouring state, and when the gear rod 81 moves, the support frame 84 and the overflow collection box 85 can be flipped up and moved into the slot 83. It should be noted that when the casting mold 1 and the casting mold 2 are about to be closed, the toothless part of the gear rod 81 is located at the bottom of the driving gear 87, and the support frame 84 and the overflow collection box 85 are moved into the slot 83 and are located below the liquid guide hole 1 88 by being pushed in by the front wall of the casting mold 2.

[0044] Reference Figures 1 to 8As shown, the knocking and vibration component 9 includes: a built-in groove 91, which is opened in the casting mold 1 and is located around the enclosure groove 72, and the built-in groove 91 is connected to the enclosure groove 72; a knocking head 92 is arranged in the built-in groove 91; the knocking and vibration component 9 also includes: a reset groove 93, which is opened at the top of the built-in groove 91 and is connected to the inside of the built-in groove 91; a movable block 94 is arranged in the inside of the reset groove 93 and fixed to the top of the knocking head 92; a spring 96 is fixed to the top of the movable block 94, and the top of the spring 96 is fixedly connected to the top of the reset groove 93; The knocking assembly 9 further includes: a tooth plate 95, fixed on the top of the movable block 94, a spring 96 wound around the outside of the tooth plate 95; an internal cavity 97, opened at the top of the reset groove 93, connected to the inside of the reset groove 93, and the top of the tooth plate 95 extends into the internal cavity 97; a connecting cavity 98, opened at one end of the internal cavity 97, connected to the inside of the internal cavity 97; a lifting gear 99, rotatably arranged in the connecting cavity 98 and meshing with the tooth plate 95; a motor 910, installed in the connecting cavity 98, and the rotating shaft of the connecting cavity 98 is fixedly connected to the lifting gear 99;

[0045] When the casting mold 1 and the casting mold 2 are molded together to inject the metal liquid, the motor 910 is started, and the motor 910 drives the lifting gear 99 to rotate. There are only 1 / 4 teeth around the lifting gear 99. When the teeth of the lifting gear 99 are engaged with the tooth plate 95, the lifting gear 99 drives the tooth plate 95 to move upward, and the tooth plate 95 drives the movable block 94 and the knocking head 92 to move upward. The movable block 94 that moves upward squeezes the spring 1 96, and the knocking head 92 that moves upward moves to the top of the built-in groove 91. At the moment when the teeth of the lifting gear 99 are separated from the teeth on the tooth plate 95, the spring 1 96 pushes the movable block 94 downward to drive the knocking head 92 to The outer wall of the enclosure frame 71 is knocked down, and the tooth plate 95 returns to the initial position under the action of the movable block 94. This can be repeated to continuously knock the side wall of the enclosure frame 71 with the knocking head 92 to generate vibration, thereby accelerating the speed at which the overflowed metal liquid flows downward and flows into the overflow collection box 85 through the liquid guide hole 1 88 and the liquid guide hole 2 89, so that the gravity sensor 810 at the bottom of the overflow collection box 85 can quickly detect the amount of overflowed metal liquid. At the same time, the vibration force generated by the knocking can also accelerate the diffusion speed of the metal liquid in the chamber composed of the mold groove 5 and the module 6, so that the metal liquid can quickly form a vortex shell in the chamber.

[0046] Reference Figures 1 to 10As shown, the touch control assembly 10 includes: a support base plate 101, which is arranged in the support frame 84 and is located at the bottom of the overflow collection box 85; a guide groove 102, which is opened on both sides of the support frame 84; a guide column 103, which is fixed inside the guide groove 102; the touch control assembly 10 also includes: a slider 104, which is fixed on both sides of the support base plate 101 and is sleeved on the outside of the guide column 103; a spring 105, which is wound around the outside of the guide column 103, and the top of the spring 105 is fixedly connected to the bottom of the slider 104; a slider 106, which is fixed on both sides of the overflow collection box 85, is located directly above the slider 104, and is sleeved on the outside of the guide column 103; a switch 107, which is installed at the bottom end of the support frame 84 and is located below the support base plate 101;

[0047] The switch 107 is electrically connected to an external preset alarm device. When the overflowed metal liquid is collected in the overflow collection box 85, the weight of the overflow collection box 85 and the collected metal liquid will push down the supporting base plate 101. The supporting base plate 101 squeezes the spring 2 105 through the slider 104. The spring 2 105 uses its own elastic force to apply a reaction force to the slider 104 to support the supporting base plate 101 and the overflow collection box 85. When too much overflowed metal liquid is collected in the overflow collection box 85, causing the supporting base plate 101 to move down and touch the switch 107, the switch 107 controls the alarm device to alarm, alerting the staff that too much overflowed metal liquid has overflowed, and reminding the staff to repair the mold.

[0048] Obviously, the above embodiments are merely examples for clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the protection scope of the invention.
