Description

Technical Field

[0001] The invention relates to the technical field of investment mold shaping equipment, in particular to a cavity investment mold shaping device. Background Art

[0002] The investment casting process is to form the casting through shell making, pouring and other processes based on the wax pattern. Among them, the molding accuracy of the investment pattern directly determines the molding accuracy of the final casting. The investment pattern still needs to be left to stand for a period of time after forming and cooling to achieve hardening of the investment pattern. During the standing process of the investment pattern, a shaping fixture is needed to fix the cooled investment pattern to avoid slight deformation of its size due to cooling shrinkage and its own gravity, and to ensure that the actual size of the investment pattern is consistent with the design state.

[0003] For example, a Chinese patent with the authorization announcement number CN216729413U discloses a lost foam casting mold support and shaping device, including a support seat and a lost foam mold arranged on the support seat; the support seat is provided with two fixing mechanisms;

[0004] A Chinese patent with authorization announcement number CN207372234U discloses a wax mold shaping tool for blade investment casting, wherein the wax mold is a blade wax mold that matches the blade design structure; the shaping tool includes a base, and the base has a shaping space that matches the blade body part in the corresponding blade design structure.

[0068] See also Figure 11-13 In the embodiment of the present invention, the constraint plate 5 includes a straight plate 51, and both ends of the straight plate 51 are fixedly connected with an L-shaped plate 52 by screws. The L-shaped plate 52 is fixedly connected to the outer wall of the side plate 11 by bolts. A U-shaped groove 53 for guiding is provided on the shell wall of the straight plate 51, and an embedded groove 54 is provided on the inner wall of the U-shaped groove 53, wherein the vertical section of the left end of the embedded groove 54 is vertical, and the vertical section of the right end of the embedded groove 54 is inclined. When the spring telescopic rod 262 enters the constraint plate 5, the ball on it first contacts the U-shaped groove 53, and under the action of the continuous downward movement of the constraint member 26 in the shaping component 2, the ball on the spring telescopic rod 262 slides into the embedded groove 54.

[0069] Due to the vertical distribution of the left end of the embedded groove 54, the spring telescopic rod 262 is prevented from being separated from the restraining plate 5 when the cover plate 25 lacks the squeezing force, ensuring that the shaping component 2 is always in a shaping and fixing state for the molten mold body when being transported on the conveying mechanism 1. The inclined setting of the right end of the embedded groove 54 allows the shaping component 2 to reset itself when it moves to the unloading station, making it convenient for the staff to unload the molten mold body on it.

[0070] The working principle of the present invention is: when it is necessary to shape and let the molten wax body with a cavity stand still, first select an appropriate shaping component 2 according to the shape of the molten wax body to be shaped, then fix the molten wax body 2 to the corresponding base 14 in turn by bolts, and adjust the filling mechanism 27 in the shaping component 2 according to the opening condition of the current molten wax body to satisfy the filling of the inner cavity of the molten wax body to be processed.

[0071] After the preparation work is completed, the driving component 3 and the cooling mechanism 4 in the product are turned on through the external control device. In the gap between the operation of the driving component 3, the mold body to be processed is placed on the base 21 at the loading station. During the placement process, the mold body is fitted with the calibration column on the base 21 to ensure the accurate placement of the mold body. After the mold body is placed, the motor 32 in the driving component 3 is operated, and the half gear 33 and the cam 36 are moved synchronously through the rotating shaft. The first half circle of the half gear 33 does not mesh with the driven gear 35, but the cam 36 realizes the relaxation of the traction rope during the synchronous movement, and then the reset spring 3 on the movable rod 37 drives the pressure plate 38 to move downward when the traction rope is relaxed. In the process of the pressure plate 38 moving downward, the cover plate 25 in the current shaping component 2 is pressed downward. In the process of the cover plate 25 moving downward, multiple square rods 24 are driven to move downward synchronously, thereby compressing the reset spring 1, and the top and bottom of the mold body are pressed tightly through the cooperation of the cover plate 25 and the base 21.

[0072] The downward movement of the plurality of square rods 24 realizes the synchronous downward movement of the restraining members 26. The spring telescopic rod 262 in the restraining member 26 slides into the U-shaped groove 53. When the cover plate 25 moves down to a proper position, the spring telescopic rod 262 slides into the embedded groove 54, and then when the pressure plate 38 is reset, the restraining member 26 will not move up, thereby ensuring the fixed shape of the investment mold body.

[0073] During the downward movement of the cover plate 25, the force is also applied to the force plate 2710 in the filling mechanism 27, so that the rack 276 moves downward under the action of the slide rail 279 and the support arm 277. During the downward movement of the rack 276, the rotating gear 275 is driven to move, thereby driving the cylinder 273 to move through the transmission shaft. During the movement, the cylinder 273 drives the joint plate 274 to move, so that the multiple round rods 272 loaded on the joint plate 274 move, stretching the reset spring 2. During the displacement adjustment process, the round rod 272 drives the carrier plate 278 to move, thereby inserting the filling material set on the carrier plate 278 into the inner cavity of the currently placed investment mold body, so as to achieve the filling of its inner cavity and ensure the qualified rate of the investment mold body after standing.

[0074] After the half gear 33 completes the first half of the rotation, it continues to move, and the cam 36 tightens the traction rope during the movement, and then the pressure plate 38 is lifted under the pull of the traction rope. However, since the constraint 26 enters the constraint plate 5, the shaping component 2 that is pressed down and adjusted will not reset. At this time, the half gear 33 is meshed with the driven gear 35 during the continuous movement, and then the corresponding rotating shaft is driven to move through the cooperation of the linkage shaft and the coupling 34, so that the current chain roller 12 moves, and then the toothed chain belt is driven to move synchronously, thereby realizing the transportation of the shaping component 2 that has been loaded, and transporting the subsequent shaping component 2 that has not been loaded to the position of the loading station.

[0075] The shaping component 2 that has completed the loading moves intermittently on the conveying mechanism 1 in a reciprocating cycle. When it moves to the position of the cooling mechanism 4, the wind blown by the cooling mechanism 4 further accelerates the hardening speed of the molten mold body in the shaping state. When the shaping component 2 with the molten mold body moves to the unloading station, the restraining member 26 in the shaping component 2 leaves the restraining plate 5, and under the action of the second and third reset springs, the cover plate 25 and the filling mechanism 27 are reset, so that the staff can unload the molten mold body in the current shaping component 2 conveniently.

[0076] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
