Description

Technical Field

[0001] The present application relates to the technical field of mold equipment, and in particular to a turbine casing mold with a detachable sand core block. Background Art

[0002] The turbine housing mold is a special mold used to manufacture the turbine housing of a turbocharger, and the sand core block is a key component in the turbine housing mold. It is usually made of a mixture of sand powder and a binder, and is made through compression molding and post-processing. The main function of the sand core block is to form the complex shape and structure inside the turbine housing to ensure the accuracy and quality of the final product.

[0003] In response to the above technical problems, a patent with announcement number CN220880421U discloses a turbine casing mold with easily removable sand core movable blocks, including a movable mold side and a static mold side, wherein at least one first sub-cavity is arranged on the movable mold side, and a second sub-cavity matching with the first sub-cavity is arranged on the static mold side, the first sub-cavity and the second sub-cavity are suitable for combining to form a mold cavity, and the mold cavity is suitable for arranging multiple first movable blocks and forming sand cores, the first movable blocks are suitable for being clamped with the formed sand cores in the form of mutual combination, and a connector is arranged between two adjacent first movable blocks, and the connector is suitable for maintaining the combination between the first movable blocks, the movable blocks of the turbine casing mold can be removed with the sand core, and the separation operation between the movable blocks and the sand core is simple and convenient, and before the movable blocks are separated, the movable blocks can be stably fixed on the sand core and are not easy to fall off.

[0004] However, the above technical solution has the following defects:

[0005] (1) When the casting is cooled and formed in the mold cavity and needs to be taken out from the mold cavity, the worker needs to take it out manually, which leads to high work intensity and fatigue. In addition, the worker's hands are easily squeezed by the mold, which poses a threat to the worker's safety. In addition, usually, after multiple castings are formed in sequence, the taken out castings may be placed in a collection container for collection and then uniformly processed in subsequent stages, or the formed castings may be directly placed on a conveyor device and enter the next processing stage. In some cases, the surface of the molded casting may have defects, such as pores, slag inclusions, cracks, etc. Therefore, in order to prevent defective castings from flowing into subsequent processing stages, it is necessary to remove the defective castings after the casting is formed. , check its surface quality, so as to timely discover and deal with unqualified products. When multiple castings are collected in a collection container and then their surface quality is checked, the castings may be piled up due to the random placement of the castings, causing the castings to cover each other, thereby affecting the inspection effect. In addition, confusion may also occur during the inspection due to the confusion of the castings. When the quality of each casting is checked and the castings are placed in a collection container or on a conveyor after inspection, it is not conducive to the inspectors to compare multiple castings, and it is not easy to find the quality differences and potential problems between the castings. It is also more laborious to manually sort the castings for the convenience of inspection. Summary of the invention

[0020] Compared with the prior art, the beneficial effects of this application are:

[0021] (1) When the casting needs to be taken out, the demoulding mechanism is used to drive the upper mold and the lower mold to separate, and then the electric push rod is used to drive the connecting block to rise, so that the two ejector rods move upward and push the casting out of the mold cavity, thereby realizing the demoulding work, thereby eliminating the process of workers manually taking out the casting, which is more convenient.

[0022] (2) Since the sand core block is installed with the lower mold by means of bolts, the sand core block can be removed from the lower mold, making it easier to replace the sand core block.

In addition, each casting is placed independently, thereby avoiding the situation where the castings are covered with each other due to random placement after being taken out, affecting the inspection effect. Each casting is moved to the worker in an orderly manner, which is relatively neat and not easy to be confused. In addition, multiple castings are placed on the turntable in a unified manner, which is also convenient for workers to compare the appearance quality of multiple castings and easily find the quality differences and potential problems between castings. At the same time, since multiple castings are placed separately in an orderly manner, it is also convenient for workers to uniformly count the number of castings. , and also provides convenience for the subsequent transfer of castings. Moreover, when the appearance quality of the castings on the limiting column is qualified, the limiting column at the corresponding position can be moved to the right side of the lifting plate, and the lifting plate can be used to lift and tilt the casting to make it slide to the hole in the middle of the turntable. The worker can place a collection container or a conveying device at the hole to make the castings with qualified appearance quality fall to the same place, thereby realizing the unified collection of castings with qualified appearance quality. Moreover, when the castings are sleeved on the limiting column, each casting can be at the same angle with the cooperation of the positioning plate and the push rod, so that each casting can be moved to the front of the worker at the same angle. Moreover, under the action of the positioning plate, the casting will not be offset due to the rotation of the turntable. At this time, the worker checks the appearance quality of the casting again, which can enable the worker to check the appearance quality of the casting at a fixed inspection rhythm, avoiding the situation that it is difficult to accurately judge the quality difference of the castings due to the change of the casting angle, which is conducive to the comparison between castings and is not prone to missed inspection or misjudgment.

[0059] Specifically, when the existing turbine casing mold is in use, after the casting is cooled and formed in the mold cavity and needs to be taken out of the mold cavity, the worker needs to manually take it out, which causes the worker to have high work intensity and is prone to fatigue. In addition, the worker's hands are easily squeezed by the mold, which poses a threat to the worker's safety. In addition, usually, after multiple castings are formed in sequence, the taken out castings may be placed in a collection container for collection, and then uniformly processed in subsequent links, or the formed castings may be directly placed on a conveying device and enter the next processing link. In some cases, the surface of the molded casting may have defects, such as pores, slag inclusions, cracks, etc. Therefore, in order to prevent defective castings from flowing into subsequent processing links, it is necessary to After the casting is formed, its surface quality must be inspected so that defective products can be discovered and dealt with in time. When multiple castings are collected in a collection container and then inspected, the castings may be piled up due to random placement, causing the castings to cover each other, thus affecting the inspection effect. In addition, confusion may occur during the inspection due to the confusion of the castings. When the quality of each casting is inspected and then placed in a collection container or on a conveyor after inspection, it is not conducive to the inspectors to compare multiple castings, and it is not easy to find the quality differences and potential problems between the castings. It is also more laborious to manually sort the castings for the convenience of inspection.

[0060] Therefore, in order to solve the above problem, when the present embodiment is in use, after the casting is ejected, the electric push rod 2 34 drives the adjusting block 36 to move so that the casting is between the two clamping plates 37, and then the motor 6 38 is used to drive the clamping plate 37 on one side to rotate, so that the two clamping plates 37 can clamp the casting with the cooperation of the two gears 2 39, and then the adjusting block 36 is driven to continue to move until the casting is above the limiting column 10. Since there is a circular through hole in the middle of the turbine shell casting, and the circular through hole belongs to the characteristics of the turbine shell structure, it will not be described in detail. When the through hole is aligned with the limiting column 10, the clamping plate 37 loosens the casting, so that the casting can be sleeved on the limiting column 10, and then the clamping plate 37 is reset, and whenever a casting is sleeved on the limiting column 10, the motor 2 17 will drive the gear 1 18 to rotate, and the turntable 9 will rotate to remove the limiting column 10 with the casting already sleeved. When multiple castings are sleeved on the limiting columns After the castings are put on the turntable 9, the worker can stand on one side of the turntable 9 and check the castings on the limit column 10 one by one by continuously rotating the turntable 9, so as to timely discover and deal with unqualified castings and avoid unqualified castings from flowing into subsequent processing procedures. In addition, each casting is placed independently, thereby avoiding the situation where the castings cover each other due to the accumulation of castings, which affects the inspection effect, and each casting is moved in front of the worker in an orderly manner, which is relatively neat and not easy to be confused. Moreover, multiple castings are placed on the turntable 9 in a unified manner, which is also convenient for workers to compare the appearance quality of multiple castings, and it is easy to find the quality differences and potential problems between the castings. At the same time, since multiple castings are placed separately in an orderly manner, it is also convenient for workers to uniformly count the number of castings, which also provides convenience for the subsequent transportation of castings, and it also saves the process of workers manually sorting the castings for the convenience of checking castings, which is more labor-saving.

[0061] When the appearance quality of the casting on the limit column 10 is qualified, the limit column 10 at the corresponding position can be moved to the right side of the lifting plate 24, and then the motor three 21 is used to drive the connecting rod one 22 and the connecting rod two 23 to rotate, so that the lifting plate 24 is inserted into the gap between the casting and the turntable 9, and then the motor five 29 is used to drive the threaded rod two 28 to rotate, so that the lifting plate 24 rises and lifts the casting. When the through hole of the casting is separated from the limit column 10, the motor four 25 drives the lifting plate 24 to rotate and tilt it, so that the casting can slide into the hole in the middle of the turntable 9. Workers can place a collection container or a conveying device at the hole to make the castings with qualified appearance quality fall to the same place, thereby realizing the unified collection of castings with qualified appearance quality for transportation, while unqualified castings need to be collected separately from qualified castings for subsequent processing.

[0062] According to the above content, although the worker only needs to stand on one side of the turntable 9, the casting can be moved in front of the worker. However, since the casting will slip after falling on the limiting column 10, the angle of each casting moved in front of the worker may be different. When the angle of each casting is different, the worker may not be able to form a fixed inspection rhythm, and may even find it difficult to accurately judge the quality difference of the castings due to the change in angle, which is not conducive to comparing the castings, resulting in missed inspections or misjudgments. In addition, it is also laborious to manually adjust the angle of the casting. Therefore, in order to avoid this problem, when a casting is about to be set on the limiting column 10, the motor 12 drives the threaded barrel 14 to rotate, so that the threaded rod 15 When the lifting rod 49 is moved upward, the telescopic rod 13 is extended, so that the push rod 42 passes through the annular groove 41 and extends upward, and the push rod 42 is at one end of the annular groove 41, and then the motor 8 56 is used to drive the threaded rod 3 55 to rotate. Since the lifting rod 49 and the fixed cylinder 16 are slidably connected by a key groove, when the threaded rod 3 55 rotates, the lifting rod 49 will move upward. When the lifting rod 49 passes through the circular hole 40 and enters the inner cavity of the limiting column 10, the rack 50 will simultaneously drive multiple gears 3 44 to rotate at the same time. When the slide groove rod 45 rotates, it will also drive the guide column 48 and the slide plate 46 to move at the same time, so that the spring 47 is compressed, and one side of the positioning plate 43 is in contact with the surface of the limiting column 10. When the casting falls above the turntable 9, Then drive the rack 50 to extend from the limiting column 10, and the positioning plate 43 is reset, so that the axis of the through hole of the casting coincides with the axis of the limiting column 10 under the action of multiple positioning plates 43. Since the main body of the turbine shell is circular and a pipe mouth extends from one side of the main body of the turbine shell, the main body of the turbine shell has a bulge, which is also a structural feature of the turbine shell and will not be described in detail. When the axis of the through hole of the casting coincides with the axis of the limiting column 10, the pipe mouth part of the casting can be just on the trajectory of the annular groove 41. At this time, the motor seven 53 is used to drive the gear four 54 to rotate, so that the rotating ring 51 can be rotated, so that the push rod 42 moves along the trajectory of the annular groove 41, and the pipe mouth part of the casting can be pushed. No matter what angle the casting is at, when the push rod 42 moves to the other end of the annular groove 41, the push rod 42 pushes the casting nozzle to make the casting at the same angle, and then the push rod 42 resets downward. At this time, the turntable 9 drives the casting to rotate again, so that each casting can be moved in front of the worker at the same angle, and under the action of the positioning plate 43, the casting will not be offset due to the rotation of the turntable 9. At this time, the worker checks the appearance quality of the casting again, and the worker can check the appearance quality of the casting at a fixed inspection rhythm, avoiding the situation where it is difficult to accurately judge the quality difference of the casting due to the change of the casting angle, which is conducive to the comparison between castings and is not prone to missed inspections or misjudgments.

[0063] The working principle of the present application is as follows: the sand core movable block 19 is placed in the mold cavity of the lower mold 3, and is fixed to the lower mold 3 with bolts to ensure the stability of the sand core movable block 19. The sand core movable block 19 is used to form the complex shape and structure inside the turbine shell, and then the upper mold 5 is driven down and contacted with the lower mold 3 by the hydraulic cylinder 7. At this time, a complete molding cavity is formed under the cooperation of the upper mold 5, the push rod 32, the sand core movable block 19, and the lower mold 3, and then the molten metal liquid is injected into the mold cavity through the pouring port of the upper mold 5. When the metal liquid is cooled and solidified in the mold cavity, a turbine shell casting with the desired shape and structure is formed. When the casting needs to be taken out, the upper mold 5 and the lower mold 3 are driven to separate, and then the electric push rod 30 is used to drive the connecting block 31 to rise, so that the two The ejector rod 32 moves upward and ejects the casting out of the mold cavity, thereby realizing demoulding, thereby eliminating the need for workers to manually remove the casting, which is more convenient. In addition, since the sand core movable block 19 can be removed from the lower mold 3, it is easier to replace the sand core movable block 19. After the casting is ejected, the electric push rod 2 34 drives the adjustment block 36 to move so that the casting is between the two clamping plates 37, and then the motor 6 38 is used to drive the clamping plate 37 on one side to rotate, so that the two clamping plates 37 can clamp the casting with the cooperation of the two gears 2 39, and then the adjustment block 36 is driven to continue moving until the casting is above the limit column 10. Since the turbine shell casting has a circular through hole in the middle, and the circular through hole is a feature of the turbine shell structure, no further elaboration is given. When the through hole is aligned with the limit column 1 0, the clamping plate 37 loosens the casting, so that the casting can be sleeved on the limiting column 10, and then the clamping plate 37 is reset, and every time a casting is sleeved on the limiting column 10, the motor 2 17 will drive the gear 18 to rotate, and the turntable 9 will rotate to remove the limiting column 10 that has been sleeved with the casting. When multiple castings are sleeved on the limiting column 10, the worker can stand on one side of the turntable 9 and check the castings on the limiting column 10 one by one by continuously rotating the turntable 9, so as to timely discover and deal with unqualified castings, thereby avoiding unqualified castings from flowing into subsequent processing procedures, and each casting is placed independently, so as to avoid the situation where the castings cover each other due to the accumulation of castings, which affects the inspection effect, and each casting moves in an orderly manner. When it comes to the workers, it is relatively neat and not easy to be confused. Moreover, multiple castings are uniformly placed on the turntable 9, which is also convenient for workers to compare the appearance quality of multiple castings and easily find the quality differences and potential problems between the castings. At the same time, since multiple castings are placed separately in an orderly manner, it is also convenient for workers to uniformly count the number of castings, which also provides convenience for the subsequent transportation of castings. When the appearance quality of the casting on the limiting column 10 is qualified, the limiting column 10 at the corresponding position can be moved to the right side of the lifting plate 24, and then the motor three 21 is used to drive the connecting rod one 22 and the connecting rod two 23 to rotate, so that the lifting plate 24 is inserted into the gap between the casting and the turntable 9, and then the motor five 29 is used to drive the threaded rod two 28 to rotate, so that the lifting plate 24 rises, and the casting is lifted.When the through hole of the casting is separated from the limiting column 10, the motor 25 drives the lifting plate 24 to rotate and tilt it, so that the casting can slide to the hole in the middle of the turntable 9. The worker can place a collection container or a conveying device at the hole to make the castings with qualified appearance quality fall to the same place, thereby realizing the unified collection of castings with qualified appearance quality for transportation. For unqualified castings, they need to be collected separately from qualified castings for subsequent processing. When the casting is about to be sleeved on the limiting column 10, the motor 12 drives the threaded barrel 14 to rotate, so that the threaded rod 15 moves upward, and the telescopic rod 13 extends, so that the push rod 42 passes through the annular groove 41 and extends upward. And the push rod 42 is at one end of the annular groove 41, and then the motor eight 56 ​​is used to drive the threaded rod three 55 to rotate. Since the lifting rod 49 and the fixed cylinder 16 are slidably connected by a key groove, when the threaded rod three 55 rotates, the lifting rod 49 will move upward. When the lifting rod 49 passes through the circular hole 40 and enters the inner cavity of the limiting column 10, the rack 50 will simultaneously drive multiple gears three 44 to rotate at the same time. When the slide groove rod 45 rotates, it will drive the guide column 48 and the slide plate 46 to move at the same time, so that the spring 47 is compressed, and one side of the positioning plate 43 is in contact with the surface of the limiting column 10. When the casting falls above the turntable 9, the rack 50 is driven to extend from the limiting column 10, and the positioning plate 43 After resetting, the axis center of the through hole of the casting can be made to coincide with the axis center of the limiting column 10 under the action of multiple positioning plates 43. Since the main body of the turbine shell is circular and a pipe mouth extends from one side of the main body of the turbine shell, the main body of the turbine shell has a bulge, which is also a structural feature of the turbine shell and will not be described in detail. When the axis center of the through hole of the casting coincides with the axis center of the limiting column 10, the pipe mouth part of the casting can be just on the track of the annular groove 41. At this time, the motor 7 53 is used to drive the gear 4 54 to rotate, so that the rotating ring 51 can be rotated, so that the push rod 42 moves along the track of the annular groove 41, and the pipe mouth part of the casting can be pushed. No matter what angle the casting is at, When the push rod 42 moves to the other end of the annular groove 41, the push rod 42 pushes the casting nozzle to make the casting at the same angle, and then the push rod 42 resets downward. At this time, the turntable 9 drives the casting to rotate, so that each casting can be moved in front of the worker at the same angle. Moreover, under the action of the positioning plate 43, the casting will not be offset due to the rotation of the turntable 9. At this time, the worker can check the appearance quality of the casting again, and the worker can check the appearance quality of the casting at a fixed inspection rhythm, avoiding the situation that it is difficult to accurately judge the difference in casting quality due to the change in the casting angle, which is conducive to the comparison between castings and is not prone to missed inspection or misjudgment.
