Description

Technical Field

[0001] This utility model relates to the field of sand casting technology, specifically to an auxiliary mold-lifting device for sand casting. Background Technology

[0002] In the sand casting process, mold removal is a crucial step. Mold removal mainly involves removing the wooden mold from inside the sand box after the sand mold is built, ensuring the completion of the sand mold so that castings can be produced later. However, the wooden mold can easily damage the sand mold during separation, so a mold removal device is needed to replace manual removal. Therefore, in order to facilitate the complete separation of the wooden mold and the sand mold, we propose an auxiliary mold removal device for sand casting.

[0003] Existing sand casting auxiliary mold-removal devices often fail to achieve thorough and efficient separation when separating wooden molds and sand molds. In practical applications, the inadequate stability during mold removal can lead to localized damage to the sand mold. This is especially true for castings with complex structures or deep cavities and narrow gaps, where the separation effect is even more insufficient. Therefore, the existing separation process is not only inefficient but also prone to sand mold waste and casting quality degradation, failing to meet the stringent requirements of modern precision casting for high separation quality and operational efficiency.

[0004] In view of this, we propose an auxiliary mold-lifting device for sand casting to solve the existing problems. Utility Model Content

[0005] The purpose of this invention is to provide an auxiliary mold-lifting device for sand casting, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sand casting auxiliary mold-lifting device, comprising a mounting platform, a clamping assembly, an electric telescopic rod, and a mounting box. The mounting platform is a U-shaped frame structure, and supports are fixedly installed on both sides of the bottom of the mounting platform. A platform is fixedly installed at the bottom of the supports, and a main control panel is fixedly installed on one side of the front of the supports.

[0007] An electric telescopic rod is bolted to the inside of the mounting platform, and a mounting cylinder is fixedly installed at the bottom of the electric telescopic rod.

[0008] A clamping assembly is fixedly installed at the bottom of the mounting cylinder. The clamping assembly includes a carrier plate. Four pneumatic telescopic rods are fixedly installed at the top of the carrier plate. The bottom end of each pneumatic telescopic rod passes through the carrier plate and is fixedly installed with a connecting valve. A suction cup is fixedly installed at the bottom of the connecting valve.

[0009] Mounting boxes are fixedly installed on both sides of the top of the platform.

[0010] Preferably, a hydraulic telescopic rod is horizontally fixedly installed inside the mounting box, and one end of the hydraulic telescopic rod extends out of the mounting box and is fixedly installed with a clamping plate. One end of the hydraulic telescopic rod is fixedly connected to the inner wall of the mounting box, and several rubber strips are fixedly installed on one side of the clamping plate.

[0011] Preferably, an electrical box is fixedly installed on the top of the electric telescopic rod, and a controller is fixedly installed inside the electrical box. The controller is electrically connected to other electronic components via a cable.

[0012] Preferably, a vibration motor is fixedly installed at the bottom inside the mounting cylinder, a vacuum pump is fixedly installed at the top inside the mounting cylinder, and the vacuum pump is connected to a connecting valve and a pneumatic telescopic rod through a gas guide pipe. An tilt sensor is fixedly installed at the center of the mounting cylinder.

[0013] Preferably, the stage has several rotating rollers rotatably mounted inside, and the top of the rollers is higher than the top surface of the stage.

[0014] Preferably, a collar is fixedly installed on the outer side of the electric telescopic rod, and limit rods are fixedly installed on both sides of the bottom of the collar. Limiting plates are fitted on the outer side of the limiting rods, and one side of the limiting plates is fixedly connected to the mounting cylinder.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model uses multiple independent adjustable suction cups to adsorb the wooden mold. During the mold removal process, the posture of the wooden mold can be dynamically adjusted in real time with the help of pneumatic telescopic rods and tilt sensors. This ensures that when the wooden mold is removed from the sand mold, the damage to the sand mold can be minimized, so as to ensure the production effect of the sand mold on the casting in the later stage.

[0017] 2. This utility model utilizes high-frequency, low-amplitude vibration generated by a vibrating motor to slightly widen the gap between the sand mold and the wooden mold during the separation of the wooden mold and the sand mold, thereby preventing large-area adhesion between the sand mold and the wooden mold and ensuring the integrity of the sand mold during the subsequent demolding process of the wooden mold.

[0023] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] like Figure 1 - Figure 4 As shown, the present invention proposes a sand casting auxiliary mold-lifting device, including a mounting platform 1, a clamping assembly 2, an electric telescopic rod 3, and a mounting box 4. The mounting platform 1 has a U-shaped frame structure, and brackets 101 are fixedly installed on both sides of the bottom of the mounting platform 1. A platform 102 is fixedly installed on the bottom of the brackets 101, and a main control panel 103 is fixedly installed on one side of the front of the brackets 101. The mounting platform 1 provides mounting positions for the surrounding components, thereby cooperating with the brackets 101 and the platform 102 to form a frame structure, so as to provide mounting positions for other components. The main control panel 103 can be connected to other electronic components through cables, so that the operator can operate the device through the main control panel 103.

[0025] An electric telescopic rod 3 is bolted to the inside of the mounting platform 1. An installation cylinder 304 is fixedly installed at the bottom of the electric telescopic rod 3. The electric telescopic rod 3 can extend and retract longitudinally, thereby driving the components at the bottom to move vertically. The installation cylinder 304 can provide the installation position for the components inside and around it.

[0026] A clamping assembly 2 is fixedly installed at the bottom of the mounting cylinder 304. The clamping assembly 2 includes a carrier plate 201. Four pneumatic telescopic rods 204 are fixedly installed at the top of the carrier plate 201. The bottom end of the pneumatic telescopic rods 204 passes through the carrier plate 201 and is fixedly installed with a connecting valve 203. A suction cup 202 is fixedly installed at the bottom of the connecting valve 203. The carrier plate 201 can provide installation positions for the surrounding components. The pneumatic telescopic rods 204 can extend and retract in the longitudinal direction, thereby driving the suction cup 202 at the bottom to move longitudinally. The suction cup 202 is connected to the vacuum pump 303 through the connecting valve 203. When the vacuum pump 303 continuously pumps air into the suction cup 202, it can apply suction to the top of the wooden mold with the help of the suction cup 202, so as to facilitate the stable removal of the wooden mold from the sand mold and avoid damage to the sand mold as much as possible.

[0027] Mounting boxes 4 are fixedly installed on both sides of the top of the stage 102, and the mounting boxes 4 can provide mounting positions for the internal components.

[0028] Furthermore, a hydraulic telescopic rod 401 is horizontally fixedly installed inside the mounting box 4, and one end of the hydraulic telescopic rod 401 extends out of the mounting box 4 and is fixedly installed with a clamping plate 402. One end of the hydraulic telescopic rod 401 is fixedly connected to the inner wall of the mounting box 4. Several rubber strips are fixedly installed on one side of the clamping plate 402. By extending and retracting the hydraulic telescopic rod 401 in the horizontal direction, the clamping plate 402 can be driven to move horizontally, thereby using the two clamping plates 402 to clamp and fix the sand box to ensure the overall stability when the wooden mold is released. The rubber strips can further improve the clamping stability between the clamping plate 402 and the sand box.

[0029] Furthermore, an electrical box is fixedly installed on the top of the electric telescopic pole 3, and a controller is fixedly installed inside the electrical box. The controller is electrically connected to other electronic components through a cable. The electrical box can be connected to an external power source and control the telescopic movement of the electric telescopic pole 3, thereby enabling the device to adjust the telescopic range of the electric telescopic pole 3 according to the actual working conditions.

[0030] Furthermore, a vibration motor 305 is fixedly installed at the bottom inside the mounting cylinder 304, and a vacuum pump 303 is fixedly installed at the top inside the mounting cylinder 304. The vacuum pump 303 is connected to the connecting valve 203 and the pneumatic telescopic rod 204 through an air guide pipe. An angle sensor 306 is fixedly installed at the center of the mounting cylinder 304. When the vibration motor 305 is powered on, it can generate high-frequency, low-amplitude vibrations, thereby driving the surrounding components to vibrate together. This helps to form a tiny gap between the wooden mold and the sand mold when the wooden mold is removed, thus facilitating the removal of the wooden mold and preventing the sand mold from sticking to the wooden mold. The vacuum pump 303 can... The suction cup 202 and the pneumatic telescopic rod 204 provide the suction and driving force required for operation, enabling the suction cup 202 and the pneumatic telescopic rod 204 to work normally. The tilt sensor 306 can monitor the tilt angle of the carrier plate 201 in real time. When the suction cup 202 contacts and adsorbs the top of the wooden mold, it can determine whether the wooden mold is in a stable state when it is lifted based on the detection data of the tilt sensor 306. When the wooden mold is in an unstable state, the tilt angle of the wooden mold can be adjusted by individually adjusting the extension length of each pneumatic telescopic rod 204, so that the wooden mold is kept in a stable state when lifting, which helps to maintain the integrity of the sand mold.

[0031] Furthermore, the platform 102 is equipped with several rotating rollers inside, and the top of the rollers is higher than the top surface of the platform 102. The rollers facilitate the transportation of sand boxes, thereby reducing the manpower required for transporting sand boxes.

[0032] Furthermore, a collar 301 is fixedly installed on the outer side of the electric telescopic rod 3, and limit rods 302 are fixedly installed on both sides of the bottom of the collar 301. Limiting plates 307 are fitted on the outer side of the limiting rods 302, and one side of the limiting plates 307 is fixedly connected to the mounting cylinder 304. The mounting cylinder 304 and the electric telescopic rod 3 are limited by the limiting rods 302 and the limiting plates 307, which can ensure the stability of the mounting cylinder 304 when moving longitudinally, thereby further preventing the carrier plate 201 from tilting significantly.

[0033] Working Principle: In actual use, the operator can place the sand box on the platform 102 and start the device through the main control panel 103. The hydraulic telescopic rod 401 drives the clamping plate 402 to firmly clamp the sand box, ensuring that the sand box will not shift or shake during the demolding process. Subsequently, the electric telescopic rod 3 drives the mounting cylinder 304 and clamping assembly 2 to descend, so that the suction cup 202 fits tightly against the top of the wooden mold. After the vacuum pump 303 is started, the suction cup 202 generates a strong suction force to firmly adhere to the wooden mold. At the same time, the vibration motor 305 starts to work, and its generated... Vibration is transmitted to the contact surface between the wooden mold and the sand mold, effectively weakening the adhesion between them and thus reducing the difficulty of demolding. The tilt sensor 306 monitors the tilt state of the carrier plate 201 in real time and feeds the data back to the controller. When the wooden mold is detected to be tilted, the controller will automatically adjust the extension length of each pneumatic telescopic rod 204 until the wooden mold returns to a horizontal state, ensuring that the demolding process is carried out smoothly. Then, by retracting the electric telescopic rod 3, the clamping assembly 2 and the wooden mold at its bottom are driven to rise steadily, separating the wooden mold from the sand mold, thus completing the demolding of the wooden mold.

[0034] The above specific embodiments are merely several preferred embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
