[0019] 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.

[0020] Example 1

[0021] like Figures 1-4 As shown, this utility model provides a technical solution: a rapid assembly device for lost foam casting molds, including a casting chamber 1, a base plate 2 fixedly connected inside the casting chamber 1, an installation groove 3 fixedly connected to the outer surface of the base plate 2, a placement plate 4 provided on the outer surface of the installation groove 3, a clamping assembly 5 provided inside the placement plate 4, the clamping assembly 5 including a handle 51, a bidirectional threaded rod 52 fixedly connected to the outer surface of the handle 51, the outer surface of the bidirectional threaded rod 52 being rotatably connected to the interior of a moving groove 7 via a bearing, a moving plate 53 being threadedly connected to the outer surface of the bidirectional threaded rod 52, a fixing rod 6 provided at the bottom of the placement plate 4, a moving groove 7 opened on the outer surface of the placement plate 4, and a fixing rod 6 opened on the outer surface of the fixing rod 6. The device has a telescopic groove 8, and a fastening assembly 9 is provided inside the telescopic groove 8. The fastening assembly 9 includes a support block 91, and sliders 92 are fixedly connected to both sides of the support block 91. The support block 91 is movable inside the telescopic groove 8, and the sliders 92 slide inside the slide groove 10. An extrusion plate 93 is attached to the outer surface of the support block 91. The extrusion plate 93 is movable inside the rotation groove 11. A connecting post 94 is fixedly connected to the outer surface of the extrusion plate 93. The connecting post 94 is movable inside the second connecting groove 12. A rotating handle 95 is fixedly connected to the outer surface of the connecting post 94. The slide groove 10 is fitted into the inner wall of the telescopic groove 8. A rotation groove 11 is opened on one side of the telescopic groove 8. A second connecting groove 12 is opened on the top of the fixing rod 6.

[0022] In this embodiment, by providing the mounting groove 3, the fixing rod 6 can be placed arbitrarily inside the mounting groove 3, thereby fixing the fixing rod 6 by the compression of the fastening component 9, that is, fixing the position of the placement plate 4. By providing the clamping component 5, the bottom end of the lost mold is clamped and stabilized. Specifically, by rotating the handle 51, the bidirectional threaded rod 52 rotates in the moving groove 7 under the support of the bearing. Due to the bidirectional thread, the moving plate 53 will move in opposite directions. The moving plate 53 has a thread inside that matches the bidirectional threaded rod 52. By providing the telescopic groove 8, it is easy to support... Block 91 is pressed from here and pressed tightly against the inner wall of the mounting groove 3. By setting the sliding groove 10 and the slider 92, the movement range of the support block 91 can be limited. By setting the rotating groove 11 and the second connecting groove 12, the connecting column 94 and the pressing plate 93 can move inside. That is, by rotating the rotating handle 95 clockwise, the connecting column 94 and the pressing plate 93 are rotated. The pressing plate 93 will gradually push the support block 91 outward due to the inclined surface set on the side of the support block 91 close to the pressing plate 93, thereby pressing it against the inner wall of the mounting groove 3. The contact surface of the support block 91 is also provided with an anti-slip layer to increase friction, making the fit more secure.

[0023] Example 2

[0024] like Figure 4 As shown, a movable hole 96 is provided on the outer surface of the rotating handle 95. A plug rod is sleeved inside the movable hole 96. A connecting plate 97 is fixedly connected to the top of the plug rod. A limiting plate 98 is fixedly connected to the outer surface of the connecting plate 97. A first connecting groove 99 is provided on the top of the connecting post 94. A limiting groove 910 is provided inside the first connecting groove 99. Fixed grooves 13 are provided on both sides of the second connecting groove 12. The outer surface of the plug rod is engaged with the inner wall of the fixed groove 13. The limiting plate 98 moves inside the limiting groove 910.

[0025] In this embodiment, in order to prevent the extrusion plate 93 from rotating, an insert rod is provided that can be inserted into the outer surface of the rotating handle 95 and the fixing rod 6 at the same time, and a limiting plate 98 is provided that is stuck in the limiting groove 910 so that the connecting plate 97 does not detach from the connecting post 94, and the limiting groove 910 allows the limiting plate 98 to move to a position sufficient to detach from the fixing groove 13.

[0026] Working principle:

[0027] like Figures 1-4As shown, during casting, the position where the lost mold will be placed is first determined, and then the fixing rod 6 is placed there. Then, the rotating handle 95 is rotated clockwise to drive the connecting column 94 and the extrusion plate 93 to rotate. The extrusion plate 93 will be gradually pushed outward by the inclined surface of the support block 91 near the side of the extrusion plate 93, thus pressing against the inner wall of the mounting groove 3. The insertion rod passes through the moving hole 96 and enters the fixing groove 13, that is, it is inserted into the outer surface of the rotating handle 95 and the fixing rod 6 at the same time. The lost mold is placed on the surface of the placement plate 4. Then, by rotating the handle 51, the bidirectional threaded rod 52, supported by the bearing, rotates in the moving groove 7 to clamp the bottom of the mold. Finally, the crushed sand and gravel can be poured out and shaken to level it for casting.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
