Description

Technical Field

[0001] The utility model relates to the technical field of sand mold conveying devices, and more specifically, to a sand mold conveying device for a molding line. Background Art

[0002] Casting is a process of melting metal into a liquid meeting certain requirements, pouring it into a mold, and obtaining a casting with a predetermined shape, size, and performance after cooling and solidification, and finishing treatment. Casting blanks can achieve the purpose of avoiding or minimizing machining due to their near-net shape, reducing costs and production time to a certain extent. A vertical parting molding machine is a commonly used processing equipment in the casting process. After the molding machine produces a sand mold, the sand mold needs to be transported to a cooling area for cooling. However, since the sand mold is easily damaged, it is necessary to prevent the force between sand molds from being unstable during transportation to avoid damaging the sand mold. Moreover, with the development of electronic control technology, molding machines have now been converted to electronic control, which has higher control accuracy and more stable operation. Therefore, higher accuracy is required during transportation, and the distance control for each transportation needs to be more accurate. Otherwise, it is difficult to match with the molding machine. However, the existing conveying device driven by a hydraulic cylinder cannot achieve such accuracy and stability during transportation. Therefore, we need a conveying device that can solve the above technical problems. Summary of the Utility Model

[0003] The utility model provides a sand mold conveying device for a molding line, which solves the problem that the conveying driven by a hydraulic cylinder in the related art cannot match an electronically controlled molding machine.

During operation, the electric cylinder assembly drives the driving member to reciprocate, and the clamping plate is connected to the driving member. Therefore, the clamping plate also reciprocates on the feeding platform. When the driving member drives the clamping plate to move in the conveying direction, the clamping plate moves on the transmission plate through the driving of the linear driving assembly, thereby clamping the sand mold and causing the sand box to move in the conveying direction following the clamping plate. When the driving member drives the clamping plate to move in the direction opposite to the conveying direction, at this time, the linear driving assembly does not drive the material clamping members to approach each other, so the sand mold will not be driven to move. As the driving member drives the clamping plate to reciprocate, the linear driving assembly drives the clamping plate to move intermittently, and continuous conveying of the sand mold can be achieved.

[0020] Beneficial effects: By directly connecting the electric cylinder assembly to the driving member, first, the driving distance of the driving member can be ensured, and the control accuracy is higher and more stable. Compared with the driving of a hydraulic cylinder, fewer parts are required, enabling the conveying device and the molding machine to share a set of electric control systems, and more energy can be saved. Without hydraulic oil, environmental pollution is reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] In this embodiment, to solve the above technical problems, a sand mold conveying device for a molding line is proposed, which includes a frame 1 and a feeding platform 2 arranged on the frame 1. It also includes a clamping member, a driving member 4, and an electric cylinder assembly 5. During operation, the electric cylinder assembly 5 drives the driving member 4 to reciprocate. Since the clamping plate 3 is connected to the driving member 4, the clamping plate 3 also reciprocates on the feeding platform 2. When the driving member 4 drives the clamping plate 3 to move in the conveying direction, the clamping plate 3 moves on the transmission plate 10 under the drive of the linear drive assembly 14, thereby clamping the sand mold and causing the sand box to move in the conveying direction following the clamping plate 3. When the driving member 4 drives the clamping plate 3 to move in the direction opposite to the conveying direction, at this time, the linear drive assembly 14 does not drive the clamping members to approach each other, so it does not drive the sand mold to move. As the driving member 4 drives the clamping plate 3 to reciprocate, the linear drive assembly 14 drives the clamping plate 3 to move intermittently, enabling continuous conveying of the sand mold.

[0033] By directly connecting the electric cylinder assembly 5 to the driving member 4, first, the driving distance of the driving member 4 can be ensured, and the control accuracy is higher. Compared with the driving of a hydraulic cylinder, fewer parts are required, enabling the conveying device and the molding machine to share a set of electric control systems and saving more energy.

Setting the guide rod 6 and the guide hole 7 can enable the driving member 4 to move in a straight line, increasing the accuracy of the driving member 4. Setting the guide wheels 9 and the guide portion 8 can also limit the driving member 4, making the movement of the driving member 4 more accurate. The guide wheels 9 limit the driving member 4 from various surfaces of the guide portion 8, with a better limiting effect and more stable movement.

The drive wheels 11 are arranged on both sides of the feeding platform 2, and the clamping plates 3 are in contact with the drive wheels 11 through the transmission plate 10, so that the clamping plates 3 move. The movement of the clamping plates 3 will be more stable. The linear drive assembly 14 can be an electric cylinder or a hydraulic cylinder. Since the linear drive assembly 14 only needs to control the movement of the clamping plates 3 and has no accurate requirement for the moving stroke, a hydraulic cylinder can be used.
