Description

Technical Field

[0001] The present invention relates to the technical field of wax part splicing tooling, and specifically to a modular splicing tooling for a complex structure wax pattern in precision casting. Background Art

[0002] Precision casting refers to the general term for the process of obtaining castings with precise dimensions. Precision casting is also called investment casting. Its products are precise, complex, and close to the final shape of the part, and can be directly used without machining or with very little machining. In precision casting, a suitable mold is required for the production of wax parts. Therefore, for complex wax parts, a complex mold structure needs to be designed, which is difficult to manufacture and makes it difficult for workers to operate during batch production, resulting in an extended production cycle. For this reason, complex wax parts are generally split into multiple modular small wax parts, and finally a splicing tooling is used to splice the multiple small wax parts into a complete complex wax part.

[0003] There is a Chinese patent with the authorization announcement number CN109590434B, which discloses a wax pattern splicing tooling for titanium alloy investment castings. The present invention solves the problem that the existing wax patterns are prone to insufficient dimensional accuracy and deformation during the welding and splicing process. It includes a workbench, first to third position adjusting members arranged above the workbench, and several limiting components.

[0004] The technical solution in the above patent document realizes the splicing and forming of a complex wax part by assisting in limiting the split small wax parts and then facilitating the bonding of each small wax part by the staff. However, there are still the following defects in the actual operation process: the single-sided splicing method is used for bonding between each small wax part, and after the single-sided splicing between each small wax part, to ensure the stability of their connection, the preliminarily bonded complex wax part needs to be removed and then repaired and bonded. Such a splicing method not only makes it difficult to ensure the stability of the splicing between each small wax part, but also requires manual flipping and adjustment when the position that needs to be repaired and bonded is inside the wax part, resulting in a large labor burden and being prone to damage the wax part during the flipping operation of the complex wax part, thus affecting the production qualification rate of the wax part and further affecting the production efficiency of the product. Summary of the Invention

[0005] To overcome the above-mentioned defects of the prior art, the present invention provides a modular splicing tooling for a wax mold with a complex structure used in precision casting. Through the bottom mold assembly and the top mold assembly in the bearing component, each small wax piece to be assembled can be placed and carried. Then, under the action of the bidirectional electric push rod, the bottom support component and the top support component approach each other. The bottom mold assembly realizes the adaptive limit of each small wax piece with the cooperation of the auxiliary component, so as to facilitate the bonding operation by the staff. Then, with the help of the driving mechanism and the flipping mechanism, the integral flipping of the bearing mechanism can be realized, so as to realize the flipping of the wax piece. With the cooperation of the adjusting mechanism, the flipped wax piece can be lifted, further facilitating the convenient bonding operation of the reverse side by the staff, so as to solve the problems proposed in the above-mentioned background technology.

[0028] Compared with the prior art, the beneficial effects of the present invention are:

[0029] Through the loading mechanism in the loading component, each small wax piece to be assembled can be loaded and placed. When the bidirectional electric push rod in the loading mechanism operates, the bottom support component and the top support component in the loading mechanism can be made to approach each other. At this time, with the cooperation of the auxiliary component, the bottom die component can realize the adaptive limiting of each small wax piece, so as to facilitate the bonding operation of the staff. It replaces the way of manually adjusting the clamping structure in the prior art to realize the clamping and limiting of the small wax piece, reduces the operation burden of the staff, and improves the work efficiency.

[0030] After the single-sided bonding of the wax piece is completed, through the cooperation of the driving mechanism and the base, the overall flipping of the loading mechanism can be realized, so as to realize the flipping of the wax piece, avoid the trouble of manually flipping the wax piece, further reduce the operation burden of the staff, prevent the wax piece from being damaged during the flipping and adjustment process, and ensure the production qualification rate and production efficiency of the wax piece.

[0031] When the loading mechanism performs the flipping movement, it synchronously drives the lifting movement of the adjusting mechanism. Furthermore, it can not only ensure the normal operation of the flipping movement of the loading mechanism, but also after the loading mechanism completes the flipping, when the bidirectional electric push rod moves, with the cooperation of the adjusting mechanism, the flipped wax piece can be jacked up, further facilitating the staff to perform the convenient bonding operation on its reverse side, so as to realize the double-sided bonding of the wax piece and ensure the stability of its bonding.

[0032] During the lifting movement of the adjustment mechanism, the stirring frame in the temporary storage mechanism can be driven to move, so as to appropriately stir the cleaning liquid temporarily stored in the water tank, avoid stratification of the cleaning liquid when it is temporarily stored in the water tank, and ensure the use effect of the cleaning liquid.

[0033] By setting the spraying mechanism, the cleaning liquid in the water tank can be extracted and sprayed, so as to realize the spraying of the cleaning liquid on the inner cavity of the bottom die assembly or the top die assembly that has contacted the wax part. And during the movement of the spraying square pipe, the angle adjustment of the flip cover can be synchronously realized, so as to shield the bottom die assembly or the top die assembly, prevent the sprayed cleaning liquid from splashing onto the wax parts located on the bearing component, and ensure the safety of the wax parts.

[0034] The setting of the spraying mechanism is combined with the flipping adjustment of the bearing mechanism in the bearing component, and then the inner cavity of the flipped bottom die assembly or top die assembly can be conveniently cleaned, avoiding the operation of manually spraying the cleaning liquid. On the one hand, it reduces the burden on the staff, on the other hand, it ensures the uniformity of the cleaning liquid spraying, and further improves the efficiency of wax part splicing, ensuring the continuity of equipment use.

When the electric push rod 61 operates, the corresponding sliding plates 212 on the two bases 21 are synchronously displaced through the U-shaped frame 62.

[0073] Please refer to Figure 9 - Figure 10 , in the embodiment of the present invention, the adjusting mechanism 3 includes a displacement frame 31 slidably connected to the inside of the workbench 1. An arched plate 32 is integrally arranged on the top of the displacement frame 31, and straight plates are fixedly connected to both sides of the top of the displacement frame 31. The sliding connection of the displacement frame 31 inside the workbench 1 ensures the stability of its lifting movement.

[0074] A connecting rod 33 is movably connected to each straight plate through a bolt pin, and the top end of the connecting rod 33 is movably connected to a swing arm 34 through a connecting pin. The two swing arms 34 are respectively fixedly connected to the corresponding rotating shafts. When the rotating shaft moves, the corresponding swing arm 34 moves, and when the swing arm 34 is adjusted during movement, the lifting adjustment of the displacement frame 31 is realized through the connecting rod 33 connected thereto.

[0075] The temporary storage mechanism 4 includes a water tank 41 fixedly connected to the rear side of the workbench 1 through bolts. A passage hole is provided on the front side wall of the water tank 41, and a moving rod 42 is movably connected in the passage hole.

During the lifting adjustment of the displacement frame 31, the pull rod 43 drives the moving rod 42 to move back and forth in the passage hole, and further drives the stirring frame 44 to move synchronously inside the water tank 41, thereby realizing the stirring of the cleaning liquid inside the water tank 41.

[0076] Please refer to Figure 1 - Figure 2 and Figure 11 - Figure 15 In the embodiment of the present invention, the spraying mechanism 5 includes a substrate 51 fixedly connected to the top wall of the table board 14 through bolts. Side plates 52 are symmetrically arranged on the top of the substrate 51 left and right, and a straight groove plate 53 is welded to the top end of the side plate 52. The straight groove plate 53 is designed to be lower in the front and higher in the rear. A spraying square pipe 54 for spraying the cleaning liquid is provided between the two straight groove plates 53, and a sensor body 55 is installed at the rear side of the spraying square pipe 54. A plurality of nozzles for spraying the cleaning liquid are linearly arranged on the bottom wall of the spraying square pipe 54. The sensor body 55 is provided for detecting the traveling position of the spraying square pipe 54. After the spraying square pipe 54 enters the position where the mold is located, the spraying of the cleaning liquid will be realized, which not only avoids waste of resources but also prevents the cleaning liquid from polluting the carrying mechanism.

[0077] A support rod 56 located on the substrate 51 is provided inside each side plate 52, and a spherical ball is rotatably connected to the top end of the support rod 56. The design of the support rod 56 and the spherical ball on its top can not only support the flap one 242 and the flap two 252 after they are turned over and adjusted, but also ensure the stability of their designed movement.

[0078] A restraint sleeve and a lifting cylinder 510 are provided on the outer wall of each side plate 52. Among them, an adjusting member 58 is movably connected in the restraint sleeve, and the two adjusting members 58 are connected through an integrating plate 59. The output end of the lifting cylinder 510 is installed on the lifting cylinder 510. By operating the lifting cylinder 510, the integrating plate 59 moves, thereby driving each adjusting member 58 connected thereto to move synchronously.

[0079] Above the adjusting member 58, there is a baffle 57. Two notches are formed on the rear shell wall of the baffle 57. A support rod is movably connected in each notch through a pin shaft, and the bottom end of the support rod is fixedly connected to the corresponding straight groove plate 53. With the pin shaft in the notch as the rotation center, when the adjusting member 58 moves up and down, under the action of gravity, the baffle 57 will perform a flipping motion around the rotation center.

[0080] On the top of the base plate 51, a water pump main body 511 is also installed. The input end of the water pump main body 511 is connected to the water tank 41 through a pipeline. The output end of the water pump main body 511 is connected to the spraying square pipe 54 through a hose. Through the water pump main body 511, the cleaning liquid in the water tank 41 of the temporary storage mechanism 4 can be pumped out and then transported to the spraying square pipe 54 for release.

[0081] The adjusting member 58 includes a bent rod 581 movably connected in a restraint sleeve, and a return plate 582 is fixedly connected to the top end of the bent rod 581. The return plate 582 and the straight groove plate 53 cooperate with each other to limit the position of the spraying square pipe 54.

[0082] A convex block 583 is integrally provided on the top of the return plate 582, and the convex block 583 is in movable contact with the baffle 57. The bottom ends of the two bent rods 581 are connected through an integrated plate 59. Slide rods are installed at both ends of the spraying square pipe 54, and the ends of the slide rods away from the spraying square pipe 54 penetrate the corresponding straight groove plates 53 and the return plate 582. When the return plate 582 moves up and down, the spraying square pipe 54 slides obliquely along the slideway of the straight groove plate 53. The two ends of the spraying square pipe 54 are also respectively slidably connected to the corresponding return plate 582, so as to ensure the stability of the spraying square pipe 54 during the movement and prevent it from flipping and causing random spraying of the cleaning liquid.

[0083] The working principle of the present invention is: when the product is used, first select an appropriate bottom mold assembly 7 and top mold assembly 8 according to the structure of the wax part to be assembled, and install the bottom mold assembly 7 on the first flap 242 of the bottom support assembly 24 in the loading member 2, while the top mold assembly 8 is assembled on the assembly plate 2531 of the loading member 253 in the top support assembly 25.

[0084] After the bottom mold assembly 7 and the top mold assembly 8 are installed on the loading member 2, a mold release agent is sprayed into the inner cavities of the bottom mold assembly 7 and the top mold assembly 8. After the mold release agent dries, the small wax parts to be spliced are sequentially placed in the bottom mold main body 71 of the bottom mold assembly 7. Then, the bidirectional electric push rod 26 of the loading mechanism in the loading member 2 is started through an external controller main body, and the synchronous operation of the bidirectional electric push rod 26 makes the bottom support assembly 24 and the top support assembly 25 in the loading mechanism approach each other.

[0085] When the bottom support assembly 24 moves upward, the lateral limit members 72 provided at the front and rear sides of the bottom die body 7 in the bottom die assembly 7 move synchronously. After the lateral limit members 72 move upward, the contact rods 724 thereon come into contact with the corresponding auxiliary members 9 provided on the frame body 22. Then, when the bottom support assembly 24 continues to move upward, after the contact rods 724 contact the wedge blocks 92 in the auxiliary members 9, the corresponding movable plates 721 are driven to move. When each movable plate 721 adjusts its displacement, the corresponding spring telescopic rods 722 arranged thereon drive the corresponding contact plates 723 to displace, and then each contact plate 723 comes into contact with the small wax pieces placed in the bottom die body 7.

[0086] Since the specifications of the respective small wax pieces are different, when the lateral limit members 72 move, the contact plates 723 cooperate with the corresponding spring telescopic rods 722 to move, thereby realizing the lateral limit of each small wax piece.

[0087] When the lateral limit of each small wax piece is completed, the external controller main body closes the bidirectional electric push rods 26. At this time, the bottom die assembly 7 realizes the stable lateral limit of the placed small wax pieces. Since the flap two 252 in the top support assembly 25 is in the open state, it will not block or hinder the wax pieces on the bottom die assembly 7. Then, the staff adhesively fixes the laterally limited small wax pieces in the bottom die assembly 7 on one side.

[0088] When the one-sided adhesive fixation of each small wax piece in the bottom die assembly 7 is completed, the external controller main body starts the synchronous movement of the two bidirectional electric push rods 26 again. At this time, the bidirectional electric push rods 26 perform an extension movement. As the bidirectional electric push rods 26 operate, the bottom support assembly 24 and the top support assembly 25 move away from each other. When the bidirectional electric push rods 26 run to the initial state, they stop running. At this time, the distance between the bottom support assembly 24 and the top support assembly 25 is at the maximum mileage. Then, the staff manually adjusts the flap two 252 in the open state in the top support assembly 25 so that it falls into the placement groove on the U-shaped plate two 251. After the flap two 252 is flipped and adjusted, the positioning bolt group 254 thereon is adjusted to stably connect the flap two 252 with the U-shaped plate two 251.

[0089] At this time, the top die assembly 8 on the loading member 253 corresponds to the bottom die assembly 7.

[0090] After the adjustment of the top support assembly 25 is completed, the external controller main body starts the contraction operation of the bidirectional electric push rods 26 again, so that the bottom support assembly 24 and the top support assembly 25 approach each other again. When the bidirectional electric push rods 26 run to the initial contracted position again, they stop running. At this time, the bottom die assembly 7 and the top die assembly 8 are closed, and the lateral limit members 72 at the front and rear side positions of the bottom die assembly 7 during its upward movement realize the secondary lateral limit of the wax pieces that have been preliminarily adhesively fixed.

[0091] After the bottom die assembly 7 and the top die assembly 8 are clamped, the electric push rod 61 in the driving mechanism 6 is started by an external controller main body to retract the U-shaped frame 62. When the U-shaped frame 62 retracts, the slide plate 212 of the corresponding base 21 in the bearing member 2 moves synchronously. When the slide plate 212 moves in displacement, the rack 213 thereon is driven to move, and the rack 213 meshes with the gear 214, thereby causing the respective corresponding rotating shafts to move. When the electric push rod 61 retracts to the maximum mileage, the rack 213 drives the gear 214 to complete a 180-degree rotational movement. The gear 214 rotates the bearing mechanism in the bearing member 2 by 180 degrees through the rotating shaft.

[0092] After the bearing mechanism completes a 180-degree rotational adjustment, the bottom support assembly 24 and the top support assembly 25 complete the position inversion and switching.

[0093] When the rotating shaft makes a 180-degree rotational adjustment, the swing arm 34 in the adjusting mechanism 3 is driven to adjust. During the movement of the swing arm 34, the displacement frame 31 moves up and down through the connecting rod 33. The up and down movement of the displacement frame 31 provides sufficient space for the switching adjustment of the bearing mechanism.

[0094] During the up and down movement of the displacement frame 31, the moving rod 42 is driven to move back and forth through the pull rod 43 in the temporary storage mechanism 4, so that the stirring frame 44 moves in the water tank 41, thereby stirring the cleaning liquid in the water tank 41.

[0095] When the rotating shaft rotates 180 degrees, the displacement frame 31 returns to the initial state. At this time, the electric push rod 61 in the driving mechanism 6 stops running. The bidirectional electric push rod 26 is started again by an external controller main body, so that the bottom support assembly 24 and the top support assembly 25 move away from each other. At this time, since the top die assembly 8 is located below, under the action of gravity, when the bottom support assembly 24 and the top support assembly 25 move away from each other, when the lateral limiting member 72 in the bottom die assembly 7 cancels the limit on the wax part, the wax part disengages from the bottom die assembly 7 and falls into the top die assembly 8.

[0096] After the bottom support assembly 24 and the top support assembly 25 move away a certain distance, at this time, the lateral limiting member 72 in the bottom die assembly 7 has cancelled the limit on the wax part, and the bottom die assembly 7 and the top die assembly 8 are separated. However, the loading member 253 in the top support assembly 25 does not contact the arched plate 32, and the operation of the bidirectional electric push rod 26 is paused by an external controller main body. Then, the adjusting bolt group in the bottom support assembly 24 is manually adjusted to disconnect it from the U-shaped plate 241. Finally, the flap 242 loaded with the bottom die assembly 7 is rotated around the pin shaft, so that the back of the flap 242 falls on the support rod 56 in the spraying mechanism 5.

[0097] Then, the operation of the bidirectional electric push rod 26 is started again through the external controller main body, and the bottom support assembly 24 and the top support assembly 25 move away from each other again. At this time, the contact frame 2533 of the loading member 253 in the top support assembly 25 at the lower position contacts the arched plate 32 during the downward movement. Since the adjusting mechanism 3 is in a fixed state at this time, after the contact frame 2533 moves downward, the movable rod 2532 is lifted, compressing the return spring, so that the assembly plate 2531 drives the top die assembly 8 to lift, which facilitates the staff to bond the wax parts that have been flipped.

[0098] Before bonding the wax parts, start the operation of each lifting cylinder 510 in the spraying mechanism 5 through the external controller main body. The lifting cylinder 510 drives the integrated plate 59 to move downward. When the integrated plate 59 moves downward, the bent rods 581 in the two adjusting members 58 drive the corresponding return plates 582 to move downward synchronously. When the return plate 582 moves downward, the sliding rod inside it slides under the cooperation of the straight groove plate 53 and the return plate 582, so that the spraying square pipe 54 moves along the direction of the straight groove plate 53. During the movement of the spraying square pipe 54, the sensor main body 55 provided on it detects its position. When the bottom die assembly 7 is detected, the sensor main body 55 transmits the information to the external controller main body, and the external controller main body starts the water pump main body 511 to operate for a period of time, extracts the cleaning liquid in the water tank 41, and inputs it into the spraying square pipe 54, and the spraying square pipe 54 realizes the spraying of the cleaning liquid. The operation time of the water pump main body 511 can only ensure that the spraying square pipe 54 sprays the cleaning liquid during the downward movement. When the spraying square pipe 54 moves upward, no cleaning liquid will be sprayed.

[0099] During the movement of the spraying square pipe 54, the sprayed cleaning liquid is used to process the inner cavity of the bottom die main body 71 in the bottom die assembly 7. The lifting cylinder 510 takes one stroke of telescopic back and forth, so as to ensure that the spraying square pipe 54 returns to its initial state after the cleaning liquid is sprayed into the inner cavity of the bottom die main body 71 in the bottom die assembly 7, so as not to hinder the adjustment of the bottom support assembly 24 in the bearing mechanism.

[0100] When the return plate 582 moves downward, the convex block 583 on it moves accordingly, so that the shielding plate 57 in contact with the convex block 583 rotates around the pin shaft of each movable connection support rod during its movement, so as to ensure that when the return plate 582 moves downward, the shielding plate 57 approaches the bottom die assembly 7, preventing the cleaning liquid from splashing onto the wax parts in the top die assembly 8 during spraying.

[0101] In a cycle, after the bearing mechanism continuously flips and switches, the spraying mechanism 5 realizes the automatic spraying of the cleaning liquid on each bottom die assembly 7 and top die assembly 8 that come into contact with the wax parts.

[0102] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes should be covered within the protection scope of the present invention.
