Description

Technical Field

[0001] This invention relates to the field of casting molding technology, specifically to a core-shooting device for water pump die casting with sand core density detection function in an intelligent casting island, and the water pump die casting itself. Background Technology

[0002] Intelligent casting islands are casting production systems that integrate automation, information technology, and intelligent technology. They achieve efficient and precise production by integrating die-casting equipment, robots, numerical simulation, and other modules. Sand cores are a crucial component in casting. Simply put, their main function is to create cavities, channels, or complex internal structures within metal castings. The die-casting core-shooting device is an important part of the die-casting machine; its core function is to inject core sand into the core box using high-pressure air and compact it, thereby quickly producing sand cores with complex shapes, precise dimensions, and high strength.

[0003] However, current mainstream die-casting core-shooting devices have the disadvantage of not being able to detect the density of the sand core inside the core box after the core sand injection and compaction process is completed. If such density abnormalities cannot be detected in time, it will directly cause the sand core to collapse and deform when subjected to the impact of molten metal, or cause defects such as porosity, shrinkage, and wall thickness deviation inside the casting. This not only reduces the qualified rate of sand core preparation, but also affects the sealing performance, mechanical strength and other key indicators of subsequent water pump die castings, increasing rework and repair costs.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and proposed a core shooting device for water pump die casting with sand core density detection function in an intelligent casting island, as well as water pump die casting. Summary of the Invention

[0007] Furthermore, the inner groove of the guide sleeve is inclined, and the guide sleeve is rotatably connected to the spray box, while the spray box is slidably connected to the sliding column.

[0008] Furthermore, the top of the return spring abuts against the spray box, and the lower end of the return spring abuts against the base plate.

[0009] Furthermore, an anti-clogging component is connected to one side of the spray box, and the anti-clogging component includes a housing. The housing is fixed to the upper outer side of the spray box, and one end of the housing is connected to an air intake hose. A support arm is fixed to one end of the air intake hose. A dustproof mesh is connected to the other end of the housing, and the dustproof mesh is connected to the interior of the spray box. A blade is slidably connected inside the housing, and a drive disc is slidably connected to the outer side of one end of the blade. A drive shaft is fixed to the middle of one side of the drive disc.

[0010] Furthermore, the support arm is fixedly connected to the lifting seat, and the lifting seat is fixedly connected to the pressure block.

[0011] Furthermore, a reducer is connected to the end of the drive shaft, and the reducer is fixedly connected to the injection box. A spline shaft is connected to the output end of the reducer, and a spline sleeve is slidably connected to the outer side of the spline shaft. A protruding post is fixed to the upper outer side of the spline sleeve, and a guide ring is slidably connected to the outer side of the protruding post. A stirring rod is provided on the outer side of the spline sleeve.

[0012] Furthermore, the groove of the guide ring is wavy, and the guide ring is fixedly connected to the reducer.

[0013] Furthermore, a feeding assembly is installed on the top of the spray box, and the feeding assembly includes an electric cylinder. The electric cylinder is fixed on the top of the spray box, and the output end of the electric cylinder is connected to a U-shaped frame. A drive column is fixed at the end of the U-shaped frame, and a sealing plate is slidably connected to the outside of the drive column. The internal groove of the sealing plate is inclined, and a connecting ear is rotatably connected to one end of the sealing plate, and the connecting ear is fixedly connected to the spray box.

[0014] Furthermore, a hanging plate is symmetrically arranged on the upper bottom surface of the lifting seat, and a light rod is symmetrically slidably connected inside the hanging plate.

[0015] A water pump die casting part is used in a water pump die casting part core shooting device with sand core density detection function in an intelligent casting island as described above.

[0016] This invention provides a core-shooting device for water pump die casting with sand core density detection function in an intelligent casting island, and a water pump die casting, which has the following beneficial effects:

[0017] 1. This invention uses an electric push rod to control the lowering of the lifting seat, which automatically aligns the spray box with the core box. During this process, the core box pushes the bottom plate, driving the baffle to rotate and open the nozzle, thus automatically connecting the spray channel. After sand spraying is completed, the lifting seat moves upward, and the reset spring pushes the baffle to close, effectively preventing core sand leakage. No manual intervention is required, which improves the automation level of the operation. At the same time, the pressure sensor monitors the weight difference before and after spraying in real time. Combined with the core box volume, the sand core density can be calculated to determine whether the product is qualified, which significantly improves the efficiency of quality inspection and the reliability of castings.

[0018] 2. In this invention, after the compressed gas enters the shell, it drives the blades to rotate the drive disc, which not only provides power for sand shooting, but also drives the stirring rod to loosen the core sand after the torque is increased by the reducer, preventing the nozzle from clogging and improving the continuity of spraying. During the rotation, the spline sleeve is also guided by the wave groove, which drives the stirring rod to achieve rotation and up-and-down reciprocating motion at the same time, forming a three-dimensional stirring effect, further enhancing the fluidity and anti-clogging ability of the core sand, realizing dual use of gas, and saving energy and efficiency.

[0019] 3. When the pressure sensor of this invention detects insufficient core sand, it drives the U-shaped frame to move via an electric cylinder, causing the drive column to slide along the inclined groove, which in turn drives the sealing plate to rotate and open. At the same time, it pushes the sliding cover to compress the spring, opening the bottom of the storage box for feeding. The pressure sensor monitors the feeding amount in real time. After reaching the set value, the electric cylinder reverses its action, and the compression spring releases first to push the sliding cover to close the storage box. Then, the sealing plate rotates back to close the spray box, forming a step-by-step sealing mechanism, which effectively avoids core sand residue and waste, and improves feeding accuracy and material utilization.

[0029] Please see Figures 1 to 4 This invention provides a technical solution: a core-shooting device for water pump die casting with sand core density detection function in an intelligent casting island, comprising a lifting base 1 and a sealing assembly 8. A storage box 2 is installed on the top of the lifting base 1, and a pressure sensor 3 is fixed on the inner side of the lifting base 1. A fixing ear 4 is connected to the top of the pressure sensor 3, and a pressure block 5 is provided above the fixing ear 4. A spray box 6 is fixed to one end of the fixing ear 4, and a nozzle 7 is installed at the bottom of the spray box 6. The sealing assembly 8 is located at the lower part of the spray box 6, and the sealing assembly 8 includes a baffle 801. The baffle is slidably connected to the inner bottom surface of the spray box 6. 801, and a guide sleeve 802 is fixed inside the baffle 801. The inner groove of the guide sleeve 802 is inclined. The guide sleeve 802 is rotatably connected to the spray box 6. The spray box 6 is slidably connected to the sliding column 806. A T-shaped rod 803 is slidably connected to the inner side of the guide sleeve 802. A return spring 804 is sleeved on the lower outer side of the T-shaped rod 803. A base plate 805 is fixed to the bottom of the T-shaped rod 803. Sliding columns 806 are installed at both ends of the bottom of the base plate 805. The top of the return spring 804 abuts against the spray box 6. The lower end of the return spring 804 abuts against the base plate 805.

[0030] The specific operation is as follows: When the external electric push rod moves the lifting seat 1 downward, the lifting seat 1 will pull the fixing ear 4 through the pressure sensor 3, causing the spray box 6 to move towards the top of the core box. The core box will support and limit the bottom of the base plate 805, causing it to squeeze the return spring 804. At the same time, it will drive the T-shaped rod 803 to move upward inside the guide sleeve 802, causing its upper end column to slide in the inclined groove inside the guide sleeve 802. At this time, the rotation of the T-shaped rod 803 is restricted by the sliding column 806. Therefore, under the push of the T-shaped rod 803, the guide sleeve 80... 2 will cause the baffle 801 to rotate, removing it from the top of the nozzle 7. This allows the nozzle 7 to automatically connect the spray box 6 with the inside of the core box after it is inserted into the opening at the top of the core box. Then, compressed gas can be supplied to the spray box 6 through an external air supply source to spray the core sand into the core box for molding. After molding, when the external electric push rod moves the lifting seat 1 upward, the return spring 804 can push the base plate 805 to move the T-shaped rod 803 downward and reset. The guide sleeve 802 will then drive the baffle 801 to rotate around the nozzle. The top of the core injection unit 7 is automatically shielded to prevent the core sand inside from falling out, requiring no additional manual operation. Subsequently, the pressure sensor 3 can detect the total weight of the injection box 6 and the core sand inside in real time. Therefore, by recording the weight difference before and after injection, the net weight of the core sand injected into the core box can be obtained. Combined with the pre-selected internal cavity volume of the core box, according to the physical formula "density = mass / volume", the density of the formed sand core can be automatically calculated to determine whether it is within the specified process error range. This online detection function integrated into the core injection device can detect abnormal sand cores in a timely manner, ensuring the performance of the subsequent casting of water pump die castings. In addition, during the process of the lifting seat 1 pulling the fixed ear 4 through the pressure sensor 3, when the pressure sensor 3 deforms and elongates under force, the pressure block 5 fixed to the lifting seat 1 will contact the fixed ear 4 in time and bear the main pulling force. This mechanical hard limit design can effectively prevent the precision pressure sensor 3 from plastic deformation or damage due to the pulling force exceeding its range, thereby greatly improving the reliability of the system and helping to extend its service life.

[0031] Please see Figures 2 to 6An anti-clogging component 9 is connected to one side of the injection box 6, and the anti-clogging component 9 includes a housing 901. The housing 901 is fixed to the upper outer side of the injection box 6, and one end of the housing 901 is connected to an air intake hose 902. A support arm 903 is fixed to one end of the air intake hose 902. The other end of the housing 901 is connected to a dustproof mesh 904, and the dustproof mesh 904 is connected to the interior of the injection box 6. A blade 905 is slidably connected inside the housing 901, and a drive disc 906 is slidably connected to the outer side of one end of the blade 905. A drive shaft 907 is fixed to the middle of one side of the drive disc 906. The support arm 903... 03 is fixedly connected to the lifting seat 1, and the lifting seat 1 is fixedly connected to the pressure block 5. The end of the drive shaft 907 is connected to the reducer 908, and the reducer 908 is fixedly connected to the spray box 6. The output end of the reducer 908 is connected to the spline shaft 909, and the outer side of the spline shaft 909 is slidably connected to the spline sleeve 910. The upper outer side of the spline sleeve 910 is fixed with the protrusion 911, and the outer side of the protrusion 911 is slidably connected to the guide ring 912. The outer side of the spline sleeve 910 is provided with the stirring rod 913. The groove of the guide ring 912 is wavy, and the guide ring 912 is fixedly connected to the reducer 908.

[0032] The specific operation is as follows: a flexible air intake hose 902 is used to connect the housing 901 to the external air supply equipment, and the air intake hose 902 is supported by a support arm 903, thereby reducing the impact when weighing the injection box 6 assembly. During the jetting process, when compressed gas enters the housing 901, it pushes the blades 905 to rotate the drive disc 906. Then, the blades 905 will also adhere tightly to the inner wall of the housing 901 under the action of centrifugal force, ensuring that the airflow power is used efficiently. Subsequently, the airflow enters the injection box 6 through its output end to supply air for the injection process. When the drive disc 906 rotates, it also transmits power to the drive shaft 907. After the torque is amplified by the reducer 908, it is then used by the spline shaft 909 and spline sleeve 910 to loosen the core sand inside the injection box 6 by the stirring rod 913, preventing the core sand from sticking together and clogging the nozzle 7, thereby improving the efficiency of the injection. Therefore, the airflow can enter the injection box 6 as the main power source for core injection. At the same time, part of the kinetic energy of the airflow is cleverly converted into the mechanical energy of the drive disc 906 rotation, thereby driving the subsequent stirring mechanism. This "one air, two uses" eliminates the need for an additional motor, making it both energy-saving and efficient. In addition, when the spline sleeve 910 rotates, it will also drive the protrusion 911 to slide in the wave groove inside the fixed guide ring 912. Since the guide ring 912 is fixed in position, the spline sleeve 910 will also produce regular up-and-down reciprocating movements while rotating, guided and constrained by the wave groove. This composite motion of "rotation + axial vibration" expands the stirring range of the stirring rod 913 from a static planar area to a dynamic three-dimensional space, which can more effectively break the adhesion tendency of the core sand and play a strong loosening and activation role on the core sand at the bottom of the injection box 6 and the inlet of the nozzle 7, thereby greatly improving the overall anti-clogging reliability.

[0033] Please see Figures 7 to 8 The top of the spray box 6 is equipped with a feeding assembly 10, which includes an electric cylinder 1001. The electric cylinder 1001 is fixed on the top of the spray box 6, and the output end of the electric cylinder 1001 is connected to a U-shaped frame 1002. The end of the U-shaped frame 1002 is fixed with a drive column 1003, and a sealing plate 1004 is slidably connected to the outside of the drive column 1003. The inner groove of the sealing plate 1004 is inclined, and a connecting ear 1005 is rotatably connected to one end of the sealing plate 1004. The connecting ear 1005 is fixedly connected to the spray box 6. A hanging plate 1006 is symmetrically arranged on the upper bottom surface of the lifting seat 1, and a light rod 1007 is symmetrically slidably connected inside the hanging plate 1006. A compression spring 1008 is sleeved on the outside of one end of the light rod 1007, and a sliding cover 1009 is fixed to the end of the light rod 1007. The sliding cover 1009 is L-shaped.

[0034] The specific operation is as follows: When the pressure sensor 3 detects that the core sand content inside the spray box 6 is low, the controller can start the electric cylinder 1001, which drives the U-shaped frame 1002 to move. This causes the drive column 1003 to slide in the inclined groove inside the sealing plate 1004, rotating and opening it around the connection point of the connecting ear 1005. During this process, the sealing plate 1004 pushes the lower end of the sliding cover 1009, causing it to compress the spring 1008 along the axial direction of the smooth rod 1007. This opens the bottom of the storage box 2. Since the bottom opening of the storage box 2 is smaller than the top opening of the lifting seat 1, the core sand inside can be released vertically. The core sand falls directly into the spray box 6. At the same time, the replenishment amount can be monitored by the pressure sensor 3. After reaching the specified threshold, the electric cylinder 1001 drives the U-shaped frame 1002 to reset. At this time, the compressed spring 1008 releases energy first, pushing the sliding cover 1009 to move axially along the light rod 1007, first completing the sealing of the bottom of the storage box 2 and cutting off the core sand flow. Then, the reset mechanism drives the sealing plate 1004 to rotate, finally completing the sealing of the top of the spray box 6. This step-by-step sealing mechanism effectively prevents the residual core sand in the storage box 2 from falling on the sealing plate 1004 during the closing process, thus preventing waste.

[0035] A water pump die casting is provided, which is applied to a core-shooting device for water pump die casting with sand core density detection function in the above-mentioned intelligent casting island. The device can ensure the stability of the sand core structure used in the casting of the water pump die casting and improve the yield of the water pump die casting.

[0036] In summary, the water pump die-casting core-shooting device and water pump die-casting parts in this intelligent casting island, which have sand core density detection function, are used as follows:

[0037] First, when the external electric push rod moves the lifting seat 1 downward, the lifting seat 1 pulls the fixing ear 4 through the pressure sensor 3, causing the spray box 6 to move towards the top of the core box. The core box will support and limit the bottom of the base plate 805, causing it to compress the return spring 804. During this process, when the pressure sensor 3 deforms and elongates under force, the pressure block 5 fixed to the lifting seat 1 will contact the fixing ear 4 in time and bear the main pulling force, preventing damage to the pressure sensor 3. Then, it can drive the T-shaped rod 803 to move upward inside the guide sleeve 802, so that its upper end column slides in the inclined groove inside the guide sleeve 802. At this time, the rotation of the T-shaped rod 803 is restricted by the sliding column 806. Therefore, under the push of the T-shaped rod 803, the guide sleeve 802 will drive the baffle 801 to rotate, removing it from the top of the nozzle 7. After the nozzle 7 is inserted into the opening at the top of the core box, it can automatically connect the spray box 6 with the inside of the core box.

[0038] Secondly, a flexible air intake hose 902 is used to connect the housing 901 to the external air supply equipment, and the air intake hose 902 is supported by a support arm 903, thereby reducing the impact when weighing the injection box 6 assembly. During the injection process, when the compressed gas enters the housing 901, it pushes the blades 905 to rotate the drive disc 906. Then, the blades 905 will also adhere tightly to the inner wall of the housing 901 under the action of centrifugal force, ensuring that the airflow power is used efficiently. Subsequently, the airflow enters the injection box 6 through its output end, injecting core sand into the core box for molding.

[0039] Next, when the drive disc 906 rotates, it will transmit power to the drive shaft 907. After the torque is amplified by the reducer 908, it will then be used by the spline shaft 909 and spline sleeve 910 to loosen the core sand inside the spray box 6 by the stirring rod 913, preventing the core sand from sticking together and clogging the nozzle 7, thereby improving the efficiency of spraying. In addition, when the spline sleeve 910 rotates, it will also drive the protrusion 911 to slide in the wave groove inside the fixed guide ring 912. Since the guide ring 912 is fixed, the spline sleeve 910 will also move up and down in a regular manner while rotating, guided and constrained by the wave groove. This will expand the stirring range of the stirring rod 913 from a static planar area to a dynamic three-dimensional space, which can more effectively break the sticking tendency of the core sand and play a strong loosening and activation role on the core sand at the bottom of the spray box 6 and the inlet of the nozzle 7, thereby greatly improving the overall anti-clogging reliability.

[0040] Then, after molding, when the external electric push rod drives the lifting seat 1 to move upward, the reset spring 804 can push the base plate 805 to make the T-shaped rod 803 move downward and reset. The guide sleeve 802 will drive the baffle 801 to automatically block the top of the nozzle 7, preventing the core sand inside from falling off. No additional operation is required. Subsequently, the pressure sensor 3 can detect the total weight of the spray box 6 and the core sand inside in real time. Therefore, by recording the weight difference before and after spraying, the net weight of the core sand injected into the core box can be obtained. Combined with the pre-selected internal cavity volume of the core box, according to the physical formula "density = mass / volume", the density of the molded sand core can be automatically calculated to ensure that it is within the specified process error range, thus ensuring the performance of the subsequent casting of water pump die castings.

[0041] Finally, after multiple core injections, when the pressure sensor 3 detects a low core sand content inside the injection box 6, the controller can activate the electric cylinder 1001, causing it to move the U-shaped frame 1002. This allows the drive column 1003 to slide within the inclined groove inside the sealing plate 1004, rotating and opening around the connection point of the connecting ear 1005. During this process, the sealing plate 1004 pushes the lower end of the sliding cover 1009, causing it to compress the spring 1008 along the axial direction of the guide rod 1007. This opens the bottom of the storage box 2. The bottom opening is smaller than the top opening of the lifting seat 1, so the core sand inside can fall vertically into the spray box 6. At the same time, the replenishment amount can be monitored by the pressure sensor 3. After reaching the specified threshold, the control electric cylinder 1001 drives the U-shaped frame 1002 to reset. At this time, the compressed spring 1008 releases energy first, pushing the sliding cover 1009 to move axially along the light rod 1007, first completing the sealing of the bottom of the storage box 2 and cutting off the core sand flow. Then, the reset mechanism drives the sealing plate 1004 to rotate, finally completing the sealing of the top of the spray box 6.
