Abstract
Description
Technical Field
[0001] This utility model relates to the field of lost foam casting production, and more specifically, it relates to a lost foam casting positioning device. Background Technology
[0002] Lost foam casting is a casting technique in which a pre-formed white foam mold is coated with refractory adhesive and dried to become a yellow mold. The yellow mold is then placed in a sand box, filled with molding sand, and vibrated to compact it. The casting process is carried out under vacuum conditions in the sand box, followed by pressure holding and cooling to form the final shape.
[0003] In the lost foam casting production line, placing the yellow mold in the sand box and initially fixing it is the "mold installation" process. After the empty sand box is filled with molding sand to a certain height through the previous "bottom sand" and compacted, the yellow mold is manually installed on top of the bottom sand, and then a small amount of molding sand is added to initially fix the yellow mold. For example... Figure 1 As shown, zero changeover time is a major advantage of lost foam casting production lines. Lost foam casting involves frequent changeovers in actual production. Depending on the product, one or more sets of yellow molds, each with its own independent casting system, can be installed in a single sand box. According to process requirements, the top of the sprue serves as a positioning point. During packing, while ensuring the sprue is vertical, the positioning points of the yellow molds need to be placed at predetermined coordinate positions in different spaces within the sand box.
[0004] However, in actual mold assembly, the positioning of the yellow mold for boxing generally relies on manual estimation or the assistance of positioning frames and rulers. The former has a great deal of uncertainty, while the latter greatly increases the difficulty of operation and is inefficient. When there are many types of products to be produced and frequent model changes are required, the number of positioning tools required also increases accordingly, and there is a risk of mishandling during operation.

[0022] The moving module includes a gear 7, a slider 6, a stepper motor 8, and a moving bracket 9. A rack 5 is provided on one side of the first slide rail 2 and one side of the second slide rail 3. A slider 6 is slidably mounted on both the first slide rail 2 and the second slide rail 3. The moving bracket 9 is fixedly mounted below the slider 6. The stepper motor 8 is fixedly mounted at the bottom of the moving bracket 9. The laser positioning module is mounted on the side of the moving bracket 9 away from the stepper motor 8.
[0023] The movable support 9 includes a base plate 10 and a side plate 11. The base plate 10 is fixedly mounted on the slider 6, and the stepper motor 8 is fixedly mounted on the base plate 10. One end of the side plate 11 is fixedly mounted on the bottom of the base plate 10. A first through hole is provided on one side of the rack 5 on the base plate 10. The drive end of the stepper motor 8 is inserted into the top of the base plate 10 through the first through hole.

By controlling the rotation of the drive end of the stepper motor 8, the gear 7 is driven to rotate. The gear 7 drives the rack 5, thereby moving the slider 6 and the laser positioning module mounted on the slider 6.
[0024] The laser positioning module includes a laser pointer 12 and an angle adjustment structure. The laser pointer 12 is mounted on the side plate 11 via the angle adjustment structure, and both the laser pointer 12 and the angle adjustment structure are electrically connected to the controller. The laser pointer 12 is used for laser positioning.
[0025] like Figure 4 As shown, the angle adjustment structure includes a turntable 13 and a servo motor 14. The turntable 13 is rotatably mounted on one side of the side plate 11, and the servo motor 14 is fixedly mounted on the other side of the side plate 11.

[0026] The length of the first slide rail 2 in this invention is 800mm. The length of the second slide rail 3 is 1200mm.
[0027] In this embodiment, a moving module and a laser positioning module are installed on the first slide rail 2, and two moving modules and two laser positioning modules are installed on the second slide rail 3.
[0028] This invention employs an RS-485 bus-based integrated absolute coordinate encoder to drive stepper motors and an RS-485 bus remote I / O module to control the laser pointer switch. After setting the coordinate origin, the stepper motor 8 does not require secondary coordinate origin establishment and retains the origin even when power is off. The integrated bus driver and remote I / O, as an industrial control standard MODBUS-RTU execution device, are integrated into the control system, touchscreen, or upper-level industrial control computer, requiring only a 24V power supply and two pairs of RS485 cables to operate. The upper-level controller can be a PLC host, a control host of a distributed control system, a touchscreen, or a host PC, etc. Based on the product model at the workstation, the controller sends positioning commands and coordinates to each stepper motor in this device and sends laser pointer switch signals to the remote I / O module. Upon receiving the commands, this device executes them to complete the corresponding model change action.
[0029] like Figure 3 As shown, this utility model provides an embodiment:
[0030] Sandbox dimensions: X = 1200mm, Y = 800mm.
[0031] The quantity of the first product to be positioned is one; the positioning points of the gating system are: X1 = 600, Y1 = 400.
[0032] The second product is packed in two boxes; the gate positioning points are: X1 = 400, Y1 = 400; X2 = 800, Y2 = 400.
[0033] When the product at the workstation is the first product.
[0034] The Y and X1 laser pointers are turned on. The X1 laser pointer is positioned at 600mm, and the Y laser pointer is positioned at 400mm. The positioning device projects a positioning point at the (600, 400) position.
[0035] When the product at the workstation is the second product.
[0036] The Y, X1, and X2 laser pointers are turned on. The X1 laser pointer is positioned at 400mm, the X2 laser pointer is positioned at 800mm, and the Y laser pointer is positioned at 400mm. The positioning device projects two positioning points at (400, 400) and (800, 400).
[0037] The working principle of this utility model is as follows:
[0038] The dimensions of the sand box to be processed are obtained and input into the controller. The controller controls the laser pointer 12 on the first slide rail 2 and the second slide rail 3 to open. The controller controls the drive end of the stepper motor 8 to rotate. The drive end of the stepper motor 8 drives the gear 7 to rotate, thereby moving the slider 6 and the laser positioning module installed on the slider 6 to the designated position. Then the controller controls the drive end of the servo motor 14 to rotate. The drive end of the servo motor 14 drives the turntable 13 and the laser pointer 12 to rotate, so that the laser pointer 12 is adjusted to the designated angle. Finally, the laser pointer 12 projects the positioning point at the designated position.
