Description

Technical Field

[0001] The invention relates to the technical field of casting, in particular to a casting device for an injection molding machine. Background Art

[0002] Castings are metal objects created through various casting methods. Liquid metal is poured through a casting process to create an object with a specific shape, size, and properties. The specific casting process includes wax pattern formation, slurry application, shell hardening, wax melting, shell casting, pouring, and shell cleaning to create the casting.

[0003] When the wax mold is dipped in slurry, in order to ensure the balance during loading, the wax mold is generally placed horizontally. When the wax mold is moved to the top of the slurry box, the wax mold is moved downward vertically from the liquid surface to allow the wax mold to enter the slurry. Since the casting is a block structure with an arc-shaped surface, a spherical groove is provided at the bottom of the wax mold during molding. Due to the existence of the spherical groove, there will be air inside the spherical groove. When the wax mold enters the liquid surface vertically, it will be squeezed by the liquid surface, and the air inside the spherical groove is not convenient to be discharged, so that the surface of the spherical groove is not fully dipped in slurry, resulting in poor dipping effect.

[0016] 1. In the casting device of the injection molding machine, when the wax mold is dipped in slurry, the movable seat moves on the guide rail, and the slurry wax mold is sent into the slurry box to be dipped in slurry. When the wax mold is dipped in slurry, the first slide bar slides in the second slide bar, so that the first slide bar can move up and down. When the first slide bar moves downward, it can drive the first tooth plate to move downward, and the first tooth plate drives the first gear to rotate. The rotation of the first gear drives the rotating seat to rotate. The rotation of the rotating seat drives the wax mold adsorbed by the suction cup to rotate, so that the wax mold can rotate a certain angle, so that the wax mold is in a tilted state. After the wax mold is tilted, the air inside the spherical groove is easily discharged, thereby reducing the situation where the surface of the spherical groove is insufficiently dipped in slurry, which is conducive to increasing the dipping effect.

[0017] 2. In the casting device of the injection molding machine, after the wax mold tilts, the movable seat moves in section b of the guide rail, driving the connecting column to slide along the first slide. When the movable seat moves along section b of the guide rail, the wax mold keeps moving in an inclined state. When the connecting column slides along the rocking portion of the first slide, the connecting column can perform left and right reciprocating motion. The left and right reciprocating motion of the connecting column drives the fixed frame to perform left and right reciprocating motion, so that the fixed frame drives the rotating seat, the positioning plate, the rotating shaft and the suction cup to perform left and right reciprocating motion, so that the wax mold can also perform left and right reciprocating motion, so as to achieve the purpose of making the wax mold perform a small swing after the wax mold tilts, thereby making it more convenient to discharge the air inside the slurry ball surface groove, increasing the sufficiency of air discharge, and further improving the slurry dipping effect.

[0018] 3. In the casting device of the injection molding machine, when the wax mold reciprocates left and right, the connecting column drives the second gear plate to move through the driving assembly, the second gear drives the second gear to rotate, the rotation of the second gear drives the first rotating shaft to rotate, the rotation of the first rotating shaft drives the suction cup to rotate, and the rotation of the suction cup drives the adsorbed wax mold to rotate, so that the wax mold can rotate in a circle along the direction of the first rotating shaft, thereby increasing the liquid flow inside the spherical groove, and the residual bubbles inside the spherical groove can be fully discharged without inconvenience, and the impact of the liquid on the surface of the spherical groove is increased, so that the surface of the spherical groove is more fully wetted with slurry, further improving the slurrying effect.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] A sliding protrusion 13 is fixed to the end of the first slide bar 12, and a track groove 14 is formed inside the second slideway 11 for the sliding protrusion 13 to slide. The track groove 14 includes a descending portion 141, an ejecting portion 142, a translation portion 143, a contracting portion 144 and an ascending portion 145 which are sequentially connected.

[0037] A second rotating shaft 15 is rotatably provided on the fixed frame 5, the rotating base 7 is fixed on the circumference of the second rotating shaft 15, a first gear 16 is fixed to the end of the second rotating shaft 15, and a first toothed plate 17 meshing with the first gear 16 is fixed to the bottom end of the first sliding rod 12;

[0038] A third slide 35 is provided on the surface of the guide rail 1, a clamping plate 36 is fixed on the upper surface of the movable seat 2, a servo motor 37 is fixed on the clamping plate 36, a third gear 38 is fixed to the output end of the servo motor 37, a running groove 39 is provided on the inner side of the third slide 35, and a rack 40 meshing with the third gear 38 is fixed to the bottom of the running groove 39.

[0039] In this technical solution, when the casting is being cast, the servo motor 37 is first used to drive the third gear 38 to rotate, and the third gear 38 is engaged with the rack 40, so that the third gear 38 moves in the walking groove 39, thereby driving the moving seat 2 to move along the guide rail 1, and the moving seat 2 drives the suction cup 10 to move, and the suction cup 10 drives the adsorbed wax mold 3 to move, and the wax mold 3 is sent into the slurry box 4, and the surface of the wax mold 3 is dipped in slurry. After the wax mold 3 is dipped in slurry, it is removed from the inside of the slurry box 4. The slurry forms a hardened shell on the surface of the wax mold 3, and then the wax mold 3 with the hardened shell is removed and placed in the heating box 41 for heating to melt the wax mold 3. A through hole is formed at the position where the suction cup 10 contacts the wax mold 3, so that the wax mold 3 flows out from the inside of the hardened shell through the through hole. The hardened shell is taken out and placed in the positioning groove 43 of the casting table 42. Casting is carried out into the hardened shell through the through hole. After casting, wait for cooling to be completed, break the hardened shell so that the hardened shell is completely removed, leaving the casting, and completing the casting work of the casting;

[0040] When the movable seat 2 moves along the guide rail 1, the movable seat 2 first moves along section a of the guide rail 1, causing the movable seat 2 to descend, and the movable seat 2 drives the wax mold 3 to descend, so that the wax mold 3 enters the slurry box 4. When the movable seat 2 moves to the bottom of section a of the guide rail 1, the slurry completely covers the wax mold 3, and then the movable seat 2 moves along section b of the guide rail 1. When the movable seat 2 moves, it drives the first slide bar 12 to slide inside the second slide rail 11, and the first slide bar 12 drives the sliding protrusion 13 to slide on the descending part 141 of the track groove 14. The relative position of the first slide bar 12 and the movable seat 2 remains unchanged. When the sliding protrusion 13 moves along the ejection part 142, the sliding protrusion 13 drives the first slide bar 12 to move downward, so that the first slide bar 12 moves downward relative to the movable seat 2, and the second slide bar 12 moves downward. The downward movement of a slide bar 12 drives the first toothed plate 17 to move downward, and the downward movement of the first toothed plate 17 drives the first gear 16 to rotate, and the rotation of the first gear 16 drives the second rotating shaft 15 to rotate, and the rotation of the second rotating shaft 15 drives the rotating seat 7 to rotate, and the rotation of the rotating seat 7 causes the adsorbed wax mold 3 to rotate, and the angle of the wax mold 3 is adjusted, so that the wax mold 3 gradually becomes an inclined state, so that the spherical groove 44 at the bottom of the wax mold 3 also tilts, and then the sliding protrusion 13 slides along the translation part 143, and the relative position of the first slide bar 12 and the moving seat 2 remains unchanged, so that the wax mold 3 is always in an inclined state until the air inside the spherical groove 44 is discharged, thereby facilitating the slurry treatment on the surface of the spherical groove 44, so that the wax mold 3 is more fully slurried;

[0041] Then the sliding protrusion 13 slides along the contraction portion 144, causing the first sliding rod 12 to move upward relative to the movable seat 2, and the first sliding rod 12 drives the first tooth plate 17 to move upward and reset, so that the first gear 16 drives the second rotating shaft 15 to reset, so that the wax mold 3 becomes horizontal again, and finally the sliding protrusion 13 slides along the rising portion 145, so that the wax mold 3 remains in a horizontal state and moves out from the inside of the slurry box 4.

[0042] In the second embodiment, since the spherical groove 44 has a certain curvature, when the wax mold 3 is in an inclined state, a small amount of air may exist at the top of the spherical groove 44, which makes the air insufficiently discharged, thereby reducing the slurry adhesion. To address this problem, this embodiment is an improvement made on the basis of the first embodiment. For details, please refer to Figures 1-14 The lower surface of the guide rail 1 is provided with a first slideway 18 for the connecting column 6 to slide. The connecting column 6 passes through the movable seat 2 and is fixed to the fixed frame 5. The movable seat 2 is provided with a through groove 19 for the connecting column 6 to slide. The inner wall of the through groove 19 is provided with a limiting groove 20. A limiting protrusion 21 is fixed on the connecting column 6, and the limiting protrusion 21 is slidably set in the limiting groove 20.

[0043] The first slideway 18 includes a stabilizing portion 181 and a rocking portion 182 . The rocking portion 182 includes a first inclined portion 1821 and a second inclined portion 1822 .

[0044] In the present technical solution, when the moving seat 2 slides along the guide rail 1, the moving seat 2 drives the connecting column 6 to slide along the first slide 18, so that the rocking portion 182 is set at the b section position of the guide rail 1. When the moving seat 2 slides along the b section of the guide rail 1, the moving seat 2 first drives the connecting column 6 to slide along the stabilizing portion 181, so that the position of the connecting column 6 and the moving seat 2 remains unchanged, and then the connecting column 6 slides along the rocking portion 182. When the connecting column 6 slides along the first inclined portion 1821, as shown in FIG. Figure 8 and Figure 9 As shown, the connecting post 6 moves to the right, and the connecting post 6 moves to the right, driving the fixed frame 5 to move to the right. The fixed frame 5 moves to the right, driving the rotating seat 7, the first rotating shaft 9 and the suction cup 10 to move to the right, thereby driving the wax mold 3 to move to the right. When the connecting post 6 slides along the second inclined portion 1822, the connecting post 6 moves to the left, and the connecting post 6 moves to the left, so that the wax mold 3 moves to the left. Through the above process, when the movable seat 2 drives the connecting post 6 to slide along the rocking portion 182, the connecting post 6 can reciprocate left and right. The reciprocating movement of the connecting post 6 can make the wax mold 3 rock left and right. When the wax mold 3 rocks left and right, the slurry can more conveniently impact the surface of the spherical groove 44, which not only makes it convenient to discharge excess air, but also makes it convenient for the slurry to contact with the surface of the spherical groove 44, further increasing the sufficiency of the slurry and improving the slurrying effect.

[0045] In this technical solution, the second slide 11 on section b of the guide rail 1 and the translation portion 143 of the track groove 14 are both set to the same track as the rocking portion 182, so that when the connecting column 6 moves left and right, the first slide bar 12 also moves left and right, thereby avoiding the fixed frame 5 from being stuck, and by setting the limiting protrusion 21 and the limiting groove 20, the limiting protrusion 21 slides inside the limiting groove 20, which can increase the stability of the connecting column 6, so that the connecting column 6 can only move left and right relative to the movable seat 2.

[0046] In the third embodiment, since the wax mold 3 is only shaken left and right, a small amount of bubbles may remain in the spherical groove 44, thereby reducing the contact effect between the slurry and the spherical groove 44, and reducing the slurry sticking effect. To address this problem, this embodiment is an improvement made on the basis of the second embodiment. For details, please refer to Figures 1-14 A second gear 22 is fixed to the top of the first rotating shaft 9, and a second tooth plate 23 is slidably provided inside the positioning plate 8. The second tooth plate 23 is engaged with the second gear 22. A driving assembly is provided between the movable seat 2 and the positioning plate 8, and the driving assembly is used to drive the second tooth plate 23 to reciprocate left and right;

[0047] The driving assembly includes a first hydraulic oil groove 24 opened inside the movable seat 2, a first piston plate 25 is slidingly arranged inside the first hydraulic oil groove 24, a first connecting rod 26 is fixed between the first piston plate 25 and the connecting column 6, a second hydraulic oil groove 27 is opened inside the positioning plate 8, a second piston plate 28 is slidingly arranged inside the second hydraulic oil groove 27, a spring 29 is fixed between the second piston plate 28 and the inner wall of the second hydraulic oil groove 27, the end of the second gear plate 23 is fixedly connected to the second piston plate 28, and an oil guide pipe 30 is arranged between the first hydraulic oil groove 24 and the second hydraulic oil groove 27.

[0048] In this technical solution, if Figure 9 As shown, when the connecting column 6 moves to the right, the connecting column 6 drives the first connecting rod 26 to move to the right, and the first connecting rod 26 drives the first piston plate 25 to move to the right, and the hydraulic oil inside the first hydraulic oil groove 24 is filled into the second hydraulic oil groove 27 through the oil guide pipe 30, so that the second piston plate 28 moves to the left, and the second piston plate 28 moves to the left to compress the spring 29, so that the spring 29 accumulates force. At the same time, the second piston plate 28 moves to the left, driving the second gear plate 23 to move to the left, and through the engagement of the second gear 22 with the second gear plate 23, the second gear 22 is driven to rotate, so that the second gear 22 rotates one circle, and the second gear 22 rotates one circle, driving the first rotating shaft 9 to rotate one circle, thereby driving the wax mold 3 to rotate one circle. When the connecting column 6 moves to the left, the first piston plate 25 moves to the left, and the hydraulic oil inside the second hydraulic oil groove 27 is sucked into the first hydraulic oil groove 24 again. At the same time, the spring 29 unloads the force, causing the second piston plate 28 to move to the right, and the second piston plate 28 drives the second gear plate 23 to move to the right. The second gear plate 23 drives the second gear 22 to rotate in the opposite direction for one circle, thereby causing the wax mold 3 to rotate in the opposite direction for one circle to reset; through the above process, when the connecting column 6 drives the wax mold 3 to shake left and right, the wax mold 3 can rotate by itself through the action of the first rotating shaft 9, making it easier to discharge bubbles, thereby further increasing the contact effect between the slurry and the spherical groove 44, further improving the sufficiency of the slurry, and achieving a better slurry effect.

[0049] Example 4: This example is another technical solution for the drive assembly. For details, please refer to Figures 1-14 The driving assembly includes a side plate 31 fixed on the surface of the moving seat 2, a spherical arc groove 32 is opened on the surface of the side plate 31, a ball 33 is arranged inside the spherical arc groove 32, a second connecting rod 34 is fixed on the surface of the ball 33, and the end of the second tooth plate 23 is fixedly connected to the second connecting rod 34.

[0050] In the present technical solution, when the connecting column 6 moves to the right, the connecting column 6 drives the fixed frame 5, the rotating seat 7 and the positioning plate 8 to move to the right. Since the position of the side plate 31 remains unchanged, the position of the second connecting rod 34 remains unchanged. The unchanged position of the second connecting rod 34 makes the position of the second tooth plate 23 remain unchanged. When the positioning plate 8 moves to the right, it drives the second gear 22 to move to the right along the second tooth plate 23, so that the second gear 22 rotates. The rotation of the second gear 22 drives the first rotating shaft 9 to rotate, thereby causing the wax mold 3 to rotate; when the connecting column 6 moves to the left, the connecting column 6 drives the fixed frame 5, the rotating seat 7 and the positioning plate 8 to move to the left, so that the second gear 22 moves to the left along the second tooth plate 23, so that the second gear 22 reverses, thereby causing the wax mold 3 to rotate in the opposite direction and reset;

[0051] By setting the spherical arc groove 32 and the ball 33, the ball 33 can be stuck in the spherical arc groove 32, so that the position of the second connecting rod 34 and the side plate 31 remains unchanged, and the ball 33 can slide inside the spherical arc groove 32, so that the second connecting rod 34 can rotate with the positioning plate 8 to avoid getting stuck.

[0052] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.

[0053] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
