Technical Field

[0001] This utility model relates to a loading and unloading vehicle, specifically a loading and unloading vehicle for an automatic shell-making line in precision casting, belonging to the technical field of automatic shell-making lines. Background Technology

[0002] Precision casting refers to the general term for processes that produce castings with precise dimensions. Compared to traditional sand casting, precision casting produces castings with more accurate dimensions and better surface finish. Automated shell-making lines for precision casting are core equipment used to produce high-precision metal castings (such as aircraft blades and medical devices), using automated processes to gradually transform wax patterns into ceramic shell molds.

[0003] However, after precision casting, the shell mold is usually hung in a movable rack. The hanging rods installed in a ring on the rack are usually in fixed positions. During the hanging process, the operator needs to adjust the posture of the shell mold according to the position of the hanging rods, which is inconvenient and makes it difficult to load and unload the shell mold during the processing. Utility Model Content

[0004] The purpose of this utility model is to provide a precision casting automatic shell-making line loading and unloading trolley to solve the above problems. The rotating shaft drives the connecting rod and the turntable to rotate. The lifting ring is lifted by a tool, which limits the hanging rod and the clamping block in the turntable. This facilitates the installation of the hanging rod on the turntable and the loading and unloading of the shell mold hanging at the end of the hanging rod.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a material loading and unloading trolley for an automatic shell-making line for precision casting, comprising a material rack, on which an installation mechanism and two fixed rods are fixedly mounted. A lifting mechanism is engaged with the installation mechanism, and a material storage mechanism is rotatably mounted on the fixed rods. The material storage mechanism includes a rotating shaft and a connecting rod. The rotating shaft is rotatably connected inside the fixed rods, and a connecting rod is fixedly mounted on the rotating shaft. A turntable is fixedly connected to the connecting rod, and a plurality of locking blocks are equidistantly engaged in a ring on the turntable. Hanging rods and lifting rings are fixedly connected to the locking blocks.

[0006] Preferably, the material storage mechanism further includes a limiting groove and a sliding groove. The turntable is provided with a plurality of limiting grooves and sliding grooves in a ring shape at equal intervals. A locking block is engaged in the limiting groove and a hanging rod is slidably installed in the sliding groove.

[0007] Preferably, the diameter of the locking block is equal to the width of the limiting groove, and the diameter of the top of the hanging rod is equal to the width of the sliding groove.

[0008] Preferably, the installation mechanism includes a support rod and a frame. The bottom end of the material rack is fixedly installed with the frame and two sets of support rods. The part of the material rack near the frame is provided with a slot. A card plate is engaged in the slot. A storage box is fixedly connected to the card plate.

[0009] Preferably, the card plate is engaged with the material rack, and the storage box is located at the bottom of a turntable.

[0010] Preferably, the storage box is located at the center of the material rack, and the width of the storage box is greater than the width of the card plate.

[0011] Preferably, the lifting mechanism includes a movable base and a locking seat, the locking seat is engaged on the locking frame, the locking seat is engaged with the movable base, and two sets of hydraulic rods are fixedly installed inside the movable base.

[0012] Preferably, the telescopic end of the hydraulic rod is fixedly connected to the card seat, and the movable base is located at the bottom of the material rack.

[0013] The beneficial effects of this utility model are as follows: The lifting mechanism drives the material rack to move towards the casting equipment. When placing the cast shell mold into the material rack, the control switch of the rotating shaft can be turned on. The rotating shaft rotates within the fixed rod installed on the material rack. The rotating shaft drives the connecting rod and the turntable to rotate. The turntable has locking blocks installed inside. Several locking blocks arranged in a ring at equal intervals rotate together with the turntable, which allows the hanging rod fixed at its bottom to rotate as well. When the hanging rod rotates to the part close to the material loading position, the shell mold can be hung on the end of the hanging rod by the robotic arm. After placement, the hanging rod rotates away to facilitate the hanging of other shell molds on the rotating hanging rod. When it is necessary to remove the entire hanging rod from the turntable, the lifting ring installed on the top of the locking block is lifted by a tool. The lifting ring drives the locking block to slide out of the turntable, separating the locking block from the inner wall of the turntable. Then, the lifting ring is moved so that the hanging rod can slide out of the turntable when it slides along the inner wall of the turntable, thus facilitating the unloading of the shell molds stored in the material rack.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-6 As shown, an automatic shell-making line for precision casting includes a material rack 1. A mounting mechanism 3 and two fixing rods 4 are fixed on the material rack 1. A lifting mechanism 2 is engaged with the mounting mechanism 3. A material storage mechanism 5 is rotatably mounted on the fixing rods 4. The material storage mechanism 5 includes a rotating shaft 501 and a connecting rod 502. The rotating shaft 501 is rotatably connected inside the fixing rods 4. The connecting rod 502 is fixedly mounted on the rotating shaft 501. A turntable 503 is fixedly connected to the connecting rod 502. A motor mounted on the fixing rods 4 drives the rotating shaft 501 to rotate, which in turn drives the connecting rod 502 and the turntable 503 to rotate. The turntable 503 is provided with a plurality of limiting grooves 505 and sliding grooves 507 in an annular shape at equal intervals. A locking block 506 is engaged in the limiting groove 505, limiting the locking block 506. When the locking block 506 is engaged with the inner wall of the turntable 503, it can prevent the hanging rod 504 from sliding in the sliding groove 507. The diameter of the locking block 506 is equal to the width of the limiting groove 505. A hanging rod 504 and a lifting ring 508 are fixedly connected to the locking block 506. The lifting ring 508 can be used to lift the locking block 506 and separate it from the inner wall of the turntable 503. The diameter of the top of the hanging rod 504 is equal to the width of the sliding groove 507.

[0023] As a technical optimization of this utility model, the installation mechanism 3 includes a support rod 301 and a frame 303. The frame 303 and two sets of support rods 301 are fixedly installed at the bottom of the material rack 1. The material rack 1 is provided with a slot 304 near the frame 303. A plate 305 is engaged in the slot 304. The slot 304 limits the position of the plate 305, which allows the operator to quickly install the storage box 302. The storage box 302 is fixedly connected to the plate 305. The storage box 302 is located at the center of the material rack 1. The width of the storage box 302 is greater than the width of the plate 305. The storage box 302 can collect the debris attached to the shell mold, thereby preventing the debris from falling onto the movable base 201 and increasing the friction between it and the material rack 1.

[0024] As a technical optimization of this utility model, the lifting mechanism 2 includes a movable base 201 and a card holder 202. The card holder 202 is engaged and installed on the card frame 303. The card holder 202 is engaged and connected to the movable base 201. Two sets of hydraulic rods 203 are fixedly installed inside the movable base 201. The telescopic ends of the hydraulic rods 203 are fixedly connected to the card holder 202. When the hydraulic rods 203 are activated, their telescopic ends can drive the card holder 202 to slide away from the movable base 201. When the card holder 202 is engaged with the card frame 303, it can lift the entire material rack 1 and separate the support rod 301 from the ground, thereby driving the material rack 1 to move.

[0025] In use, the movable base 201 moves to the bottom of the material rack 1. Then, the hydraulic rod 203 drives the card holder 202 installed on the top of the movable base 201 to slide. During the upward movement, the card holder 202 can engage with the card frame 303 installed at the bottom of the material rack 1. When the card holder 202 contacts the bottom of the material rack 1, the entire material rack 1 can be lifted off the ground, and the support rod 301 fixed on the material rack 1 separates from the ground, which facilitates the movable base 201 to move the material rack 1 towards the casting equipment during travel. When placing the cast shell mold into the material rack 1, the control switch of the rotating shaft 501 can be turned on. The rotating shaft 501 rotates within the fixed rod 4 installed on the material rack 1. The rotating shaft 501 drives the connecting rod 502 and the turntable 503 to rotate. The turntable 503 has card blocks 506 engaged inside. Several card blocks 506 arranged in a ring at equal intervals rotate with the turntable 503, which can also rotate the hanging rod 504 fixed at its bottom. When the hanging rod 504 rotates to the position near the loading point, the shell mold can be hung on the end of the hanging rod 504 by the robotic arm. After placement, the hanging rod 504 rotates away to facilitate the hanging of other shell molds onto the rotating hanging rod 504. When it is necessary to remove the entire hanging rod 504 from the turntable 503, the lifting ring 508 installed on the top of the clamping block 506 is lifted by a tool. The lifting ring 508 drives the clamping block 506 to slide out of the turntable 503, so that the clamping block 506 and the turntable 503 are aligned. The inner wall of 03 is separated, and then the lifting ring 508 is moved so that the hanging rod 504 can slide out of the turntable 503 when it slides along the inner wall of the turntable 503, which facilitates the unloading of the shell mold stored in the material rack 1; the slot 304 provided in the material rack 1 is fitted with a card plate 305, and the storage box 302 fixed on the card plate 305 can collect the debris attached to the shell mold, thereby preventing the debris from falling onto the moving base 201 and increasing the friction between it and the material rack 1.
