Description

Technical Field

[0001] The invention relates to the technical field of bearing seat casting, and in particular to a casting device for bearing seat processing. Background Art

[0002] In the modern machinery manufacturing industry, the quality and processing accuracy of the bearing seat as an important component directly affect the performance and service life of the whole machine. The traditional bearing seat processing methods mainly include casting, forging and machining processes. Among them, casting is widely used due to its high material utilization rate, high production efficiency and the ability to form complex shapes.

[0003] The existing publication number CN118357437A discloses a casting device for a bearing seat, which includes an injection machine, a middle mold, a lower mold unit, and an upper mold. There are two lower mold units, and the two lower mold units are connected to form a complete lower mold group. The lower mold group and the middle mold are spliced ​​to form a cavity of a complete bearing annular base. After the lower mold group and the middle mold are spliced, a complete pouring hole for the injection machine to inject molten metal is formed, and the runner axis is on the splicing surface of the lower mold unit; the upper mold descends and ejects the material to discharge the material, and the bearing seat naturally descends, and is lowered by the flat support of the lower mold unit to achieve vertical and smooth demolding of the bearing seat.

[0004] Although the above technical solution can utilize the natural mold opening movement of the lower mold unit to realize workpiece demolding and transportation, and has the advantages of simple structure and continuous production, in the prior art, when casting the bearing seat, it is necessary to inject the molten metal into the mold cavity through the pouring gate. During the injection of the molten metal, the operator needs to manually control the container containing the molten metal to flip over to achieve the injection, and observe whether the molten metal overflows the pouring gate during the injection process. This process not only requires the operator to have certain experience and skills, but also in the process of injecting the molten metal, it is often difficult to accurately control the injection amount, and the molten metal enters the mold cavity through the pouring gate, and the pouring gate itself will also be filled with the molten metal. This results in that after the casting is completed, the pouring gate is connected to the main casting, forming certain casting defects, and the pouring gate needs to be knocked off after the mold is removed to separate it from the main casting. This additional process increases the complexity of the production process and also prolongs the production cycle. Therefore, a new type of casting device for bearing seat processing is needed to solve the above problems. Summary of the invention

[0046] A liquid storage mechanism 3 is provided on the support platform 13, and the liquid storage mechanism 3 includes a bracket 31 fixed on the support platform 13, a molten iron tank 32 installed on the bracket 31, a discharge channel 33 provided at the bottom end of the molten iron tank 32, and a valve body 34 installed on the discharge channel 33. The liquid storage mechanism 3 is made of a refractory material, wherein the refractory material can be cast iron or a high-temperature resistant alloy;

[0047] A quantity control mechanism 4 is also provided on the support platform 13;

[0048] Specifically, refer to Figure 3 , Figure 8-Figure 9 The control mechanism 4 includes a main rod 41 fixed on the support platform 13, a transmission shaft 42 rotatably arranged in the main rod 41, a top plate 43 fixed on the top of the transmission shaft 42, a quantitative cylinder 44 symmetrically arranged in the front and rear positions of the top plate 43, a shaft 45 fixedly connected to the main rod 41, a sleeve rod 46 that can be lifted and lowered outside the shaft 45, a bottom plate 47 rotatably arranged on the sleeve rod 46, and a liquid discharge cylinder 48 symmetrically arranged in the front and rear positions of the bottom plate 47, and the bottom end of the liquid discharge cylinder 48 is provided with an opening and closing mechanism 5 for opening or closing, and the bottom end of the quantitative cylinder 44 is inserted into the liquid discharge cylinder 48. When one group of quantitative cylinders 44 is located directly below the discharge channel 33, the other group of quantitative cylinders 44 is located above the mold assembly 2, wherein the bottom plate 47 is rotatably sleeved on the sleeve rod 46 through a bearing;

[0049] By providing a quantity control mechanism 4, the quantity of the molten metal injected into the mold assembly 2 each time can be accurately controlled, thereby preventing the molten metal from overflowing. The operator does not need to pay attention to whether the molten metal overflows the pouring port 23. By improving the injection process, the pouring port 23 is prevented from being filled with liquid metal and causing the pouring port 23 to be connected to the main casting. In addition, the double-group design allows one group of metering cylinders 44 and liquid discharge cylinders 48 to be casting while the other group of metering cylinders 44 and liquid discharge cylinders 48 are preparing the next batch of liquid metal, which has the advantages of shortening the production cycle and improving production efficiency.

[0050] Specifically, refer to Figure 3-Figure 7The opening and closing mechanism 5 includes a bottom cover 51 disposed at the bottom end of each group of liquid discharge cylinders 48, an arm 52 fixed on the bottom cover 51, a connecting seat 53 fixed on the arm 52, and a fixed seat 54 fixed on the liquid discharge cylinder 48, the connecting seat 53 is rotatably connected to the fixed seat 54 through a rotating shaft 55, and both ends of the rotating shaft 55 are provided with torsion springs 56, wherein the two ends of the torsion spring 56 are respectively abutted against the end surfaces of the connecting seat 53 and the fixed seat 54;

[0051] The opening and closing mechanism 5 also includes a guide ring 57 fixed on the sleeve rod 46 and an arc-shaped notch 58 opened on the lower surface of the guide ring 57 close to the side of the mold assembly 2. The upper surface of the arm rod 52 away from the end of the bottom cover 51 abuts against the lower surface of the guide ring 57. The arm rod 52 abuts against the lower surface of the guide ring 57, so that the bottom cover 51 fits against the bottom end of the liquid discharge cylinder 48.

[0052] Furthermore, an abutment ring 59 is fixed to the sleeve rod 46, and the abutment ring 59 is located below the guide ring 57. The lower surface of the arm rod 52 away from the bottom cover 51 abuts against the upper surface of the abutment ring 59, and an annular slide is formed between the abutment ring 59 and the guide ring 57. The arm rod 52 can slide in the annular slide. When the upper surface of the arm rod 52 abuts against the lower surface of the guide ring 57, the limiting of the abutment ring 59 can further improve the limiting of the arm rod 52, so that the bottom cover 51 can fit tightly against the bottom end of the liquid discharge cylinder 48.

[0053] The arm 52 contacts the lower surface of the guide ring 57 and the upper surface of the abutment ring 59, thereby controlling the bottom cover 51 to fit tightly against the bottom end of the liquid discharge tube 48, shielding and sealing the bottom end of the liquid discharge tube 48, thereby preventing the molten metal stored in the metering tube 44 and the liquid discharge tube 48 from flowing out. When the transmission shaft 42 drives the top plate 43, the metering tube 44, the bottom plate 47 and the liquid discharge tube 48 to rotate as a whole, the arm 52 rotates along the annular slideway formed between the guide ring 57 and the abutment ring 59 until the arm 52 rotates to the arc-shaped notch 58. At this time, under the torsion control of the torsion spring 56, the bottom cover 51 is controlled to flip around the rotating shaft 55 as the center, so that the bottom end of the liquid discharge tube 48 is in an open state. At this time, the molten metal stored in the metering tube 44 and the liquid discharge tube 48 is discharged through the bottom end of the liquid discharge tube 48.

[0054] By arranging an opening and closing mechanism 5 at the bottom of the double-group switchable liquid discharge cylinder 48, while one group of metering cylinder 44 and liquid discharge cylinder 48 are injecting liquid, the other group of metering cylinder 44 and liquid discharge cylinder 48 can reserve molten metal to be used next time, thereby making the casting process more efficient and reducing the production cycle.

[0055] When a set of metering cylinder 44 and liquid discharge cylinder 48 rotate to the top of the casting mold assembly 2, the corresponding bottom cover 51 is controlled to rotate automatically, so that the bottom end of the liquid discharge cylinder 48 is in an open state, so that the molten metal can flow smoothly into the casting mold assembly 2;

[0056] The other set of metering cylinder 44 and liquid discharge cylinder 48 can be rotated to the bottom of the molten iron tank 32, and the bottom cover 51 at the bottom end of the liquid discharge cylinder 48 can achieve the function of shielding and sealing the bottom end of the liquid discharge cylinder 48 under the limiting action of the annular slide formed between the guide ring 57 and the abutment ring 59, thereby ensuring that the molten metal can be injected into the corresponding metering cylinder 44 through the molten iron tank 32.

[0057] Further, see Figure 3 and Fig.10 The control mechanism 4 also includes a guide plate 49, which includes a fixed plate 491 fixed on the main rod 41, a groove 492 and a liquid outlet groove 493 provided on the fixed plate 491, the groove 492 and the liquid outlet groove 493 are interconnected, the groove 492 is located below the liquid outlet cylinder 48, and the liquid outlet groove 493 is located directly above the pouring port 23, wherein the end of the liquid outlet groove 493 away from the groove 492 is gradually narrowed, and the outlet end of the liquid outlet groove 493 away from the groove 492, the diameter of the pouring port 23 is greater than The outlet width of the liquid outlet groove 493 and the width of the groove 492 are greater than the diameter of the bottom end of the liquid outlet tube 48. This design is to better guide the molten metal. When the bottom end of the liquid outlet tube 48 is in an open state, the molten metal stored in the metering cylinder 44 and the liquid outlet tube 48 is discharged through the bottom end of the liquid outlet tube 48. After being discharged through the liquid outlet tube 48, the molten metal flows into the groove 492 and enters the pouring port 23 along the groove 492 and the liquid outlet groove 493 until it fills the complete bearing seat cavity formed by the splicing of the lower mold assembly 21 and the upper mold assembly 22.

[0058] The bottom end of the transmission shaft 42 passes through the support platform 13 and is provided with a driving mechanism 6;

[0059] Specifically, refer to Figure 3 , Figure 8-Figure 9 The driving mechanism 6 includes a first motor 61 installed at the bottom of the support platform 13, an output shaft 62 fixed to the output end of the first motor 61, a half gear 63 fixed on the output shaft 62, and a driven gear 64 meshing with the half gear 63. The driven gear 64 is fixed to the bottom end of the transmission shaft 42, and the output shaft 62 is rotatably arranged at the bottom of the support platform 13. The first motor 61 is installed at the bottom end of the support platform 13 through a mounting frame. When the first motor 61 is started, the output shaft 62, the half gear 63 and the driven gear 64 are driven to rotate, so that the driven gear 64 can drive the transmission shaft 42, the top plate 43, the quantitative cylinder 44, the bottom plate 47, the liquid discharge cylinder 48 and the bottom cover 51 to rotate as a whole.

[0060] During use, when it is necessary to inject molten metal into the complete bearing seat cavity formed by splicing the lower mold assembly 21 and the upper mold assembly 22, first, one set of the metering cylinder 44 and the liquid outlet cylinder 48 is located below the liquid storage mechanism 3, and the other set of the metering cylinder 44 and the liquid outlet cylinder 48 is located above the mold assembly 2. The metering cylinder 44 and the liquid outlet cylinder 48 located below the liquid storage mechanism 3 are activated by the valve body 34, so that the molten metal in the molten iron tank 32 enters the metering cylinder 44 and the liquid outlet cylinder 48 through the discharge channel 33. At this time, the annular channel formed between the guide ring 57 and the abutment ring 59 limits the arm 52, so that the bottom cover 51 is tightly attached to the corresponding liquid outlet cylinder 48. The bottom end of the liquid discharge cylinder 48 is shielded and sealed, and a group of metering cylinders 44 and liquid discharge cylinders 48 located above the mold assembly 2 release the limit on the upper surface of the arm 52 through the arc-shaped notch 58 provided on the guide ring 57, so that the bottom cover 51 and the arm 52 can rotate around the rotating shaft 55 under the torsion of the torsion spring 56, so that the bottom end of the corresponding liquid discharge cylinder 48 is in an open state. At this time, the molten metal stored in the corresponding metering cylinder 44 and liquid discharge cylinder 48 flows down through the bottom end of the liquid discharge cylinder 48, and enters the pouring port 23 along the groove 492 and the liquid discharge groove 493 until it fills the bearing seat cavity formed by the lower mold assembly 21 and the upper mold assembly 22;

[0061] When a set of metering cylinders 44 and a liquid outlet cylinder 48 located below the liquid storage mechanism 3 are filled with molten metal, and the molten metal in another set of metering cylinders 44 and a liquid outlet cylinder 48 located above the mold assembly 2 is injected into the bearing seat cavity, the discharge channel 33 is closed at this time, and the next mold assembly 2 to be cast is replaced, and then the first motor 61 is started, and the output shaft 62 is controlled to rotate by the first motor 61, so that the output shaft 62 drives the half gear 63 to rotate one circle, and when the toothed part of the half gear 63 contacts the driven gear 64, the driven gear 64 rotates, and at the same time controls the transmission shaft 42 to rotate, and during the rotation of the transmission shaft 42, the top plate 4 is controlled 3. The measuring cylinder 44, the bottom plate 47, the liquid discharge cylinder 48, the bottom cover 51, the arm 52, the connecting seat 53, the fixing seat 54, the rotating shaft 55 and the torsion spring 56 are rotated, and then the positions of the two groups of measuring cylinders 44 and the liquid discharge cylinders 48 are exchanged, so that one group of measuring cylinders 44 and the liquid discharge cylinders 48 originally located below the liquid storage mechanism 3 is rotated to the top of the mold assembly 2, and the bottom cover 51 corresponding to the bottom end of the liquid discharge cylinder 48 is flipped open to realize liquid injection, while the other group of measuring cylinders 44 and the liquid discharge cylinders 48 originally located above the mold assembly 2 is rotated to the bottom of the liquid storage mechanism 3, and the bottom cover 51 corresponding to the bottom end of the liquid discharge cylinder 48 is flipped closed to store liquid.

[0062] Further, see Fig.11The sleeve rod 46 is sleeved on the outside of the shaft rod 45 through a spline shaft, and a bolt 461 is threadedly connected to the sleeve rod 46. The shaft rod 45 is provided with multiple sets of screw holes 462 corresponding to the bolts 461. By controlling the sleeve rod 46 to move up and down on the shaft rod 45, the bottom plate 47, the liquid discharge cylinder 48 and the opening and closing mechanism 5 can be controlled to move up and down as a whole. The liquid discharge cylinder 48 moves up and down at the bottom of the quantitative cylinder 44, and the capacity of the quantitative cylinder 44 and the liquid discharge cylinder 48 can be adjusted. After adjustment, the position of the sleeve rod 46 can be fixed by rotating the bolt 461 to connect it with the corresponding screw hole 462, and then it can be applied to mold assemblies 2 of various specifications.

[0063] The materials of the quantity control mechanism 4 and the opening and closing mechanism 5 are consistent with the material of the liquid storage mechanism 3, and are both refractory materials, wherein the refractory materials may be cast iron or high temperature resistant alloys.

[0064] A reciprocating mechanism 7 is provided on the workbench 11;

[0065] Specifically, refer to Figure 12-14 The reciprocating mechanism 7 includes an outer frame 71 slidably arranged on the workbench 11, a pulley 72 fixed on the outer frame 71, a cam 73 in sliding contact with the pulley 72, and a connecting shaft 74 fixed on the cam 73. The connecting shaft 74 passes through the workbench 11 and is fixedly provided with a second motor 75. The second motor 75 is installed at the bottom end of the workbench 11, wherein the output end of the second motor 75 is fixedly connected to an end of the connecting shaft 74 away from the cam 73. When the second motor 75 is started, the connecting shaft 74 is controlled to drive the cam 73 to rotate, and the sliding contact between the cam 73 and the pulley 72 is utilized to control the outer frame 71 to slide on the workbench 11;

[0066] Among them, the mold assembly 2 is placed in the outer frame 71, a slider 711 is fixed to the bottom end of the outer frame 71, a fixing block 712 is fixed on the slider 711, a spring 713 is fixed on the fixing block 712, a connecting plate 714 is fixed to the other end of the spring 713, and the connecting plate 714 is fixed on the workbench 11. The workbench 11 is provided with a slide groove 715 for the slider 711 to slide. In the process of the outer frame 71 sliding on the workbench 11, the outer frame 71 drives the slider 711 to slide in the slide groove 715, and then controls the spring 713 to be compressed and released, so that the outer frame 71 reciprocates on the workbench 11 to achieve vibration of the mold assembly 2. By vibrating the mold assembly 2, the fluidity of the molten metal in the mold assembly 2 can be improved, the molten metal can be arranged more densely during filling, the porosity inside the casting can be reduced, the filling effect can be enhanced, and the quality of the casting can be improved.

[0067] Furthermore, a pushing mechanism 8 is also provided on the support table 13, and the pushing mechanism 8 includes an electric push rod 81 installed on the support table 13, and a push plate 82 is fixed to the output end of the electric push rod 81. After the mold assembly 2 completes the injection and vibration, the electric push rod 81 is started to control the movement of the push plate 82, and then the mold assembly 2 in the outer frame 71 is pushed to the transfer table 12, so that the operator can quickly place the next mold assembly 2 to be injected with liquid, wherein the width of the push plate 82 is smaller than the width of the mold assembly 2, so as to facilitate the push plate 82 to push the mold assembly 2 out of the outer frame 71.

[0068] It is worth noting that the height of the transfer platform 12 is flush with the inner bottom wall of the outer frame 71 , and when the mold assembly 2 is moved by the electric push rod 81 and the push plate 82 , it can move to the transfer platform 12 more smoothly.

[0069] During use, after the metering cylinder 44 and the liquid discharge cylinder 48 located above the mold assembly 2 inject molten metal into the mold assembly 2, the second motor 75 is started to control the connecting shaft 74 to drive the cam 73 to rotate, and the sliding contact between the cam 73 and the pulley 72 is utilized to control the outer frame 71 to slide on the workbench 11. During the sliding process of the outer frame 71, the slider 711 is driven to slide in the slide groove 715, thereby squeezing the spring 713. As the cam 73 rotates continuously, the spring 713 is squeezed and then released, thereby controlling The control slide block 711 slides in the slide groove 715, and at the same time drives the outer frame 71 to reciprocate on the workbench 11, thereby realizing the vibration of the mold assembly 2. After completing the vibration of the mold assembly 2, the electric push rod 81 is started, so that the electric push rod 81 controls the push plate 82 to move, and then pushes the mold assembly 2 in the outer frame 71 to move to the transfer table 12. After that, the operator quickly places the next mold assembly 2 to be filled with liquid, and then starts the first motor 61 to exchange the positions of the two sets of metering cylinders 44 and liquid discharge cylinders 48.
