Description

Technical Field

[0001] This utility model relates to the technical field of surface oxidation treatment device for lost foam molds, and in particular to a surface oxidation treatment device for lost foam molds. Background Technology

[0002] Lost foam is a solid model made of foam plastic that perfectly matches the shape of the casting. In the lost foam casting process, it gradually vaporizes and disappears during the pouring process, thus forming the required casting cavity.

[0003] After a period of use, existing lost foam casting molds develop rust stains on their outer surface. These rust stains are typically treated using laser rust removal machines. However, the laser rust removal gun requires manual control by the operator, and the rust removal process on lost foam casting molds is relatively slow. Consequently, operators experience significant fatigue when holding the rust removal gun for extended periods, potentially affecting the efficiency of rust removal. Therefore, the existing method of using laser rust removal machines for rust removal on lost foam casting molds is inconvenient. To address this, we provide a surface oxidation treatment device for lost foam casting molds. Utility Model Content

[0006] In a preferred embodiment, a limiting ring is sleeved on the outer surface of one end of the fixed rod, and the limiting ring is fixedly connected to the fixed rod. An embedded block is sleeved inside the sliding rod, and the embedded block is fixedly connected to the fixed rod.

[0007] In a preferred embodiment, the horizontal block is fixedly connected to the embedded block, the threaded bracket is sleeved inside the horizontal block, and the threaded bracket is slidably connected to the horizontal block.

[0008] In a preferred embodiment, the threaded frame is fixedly connected to the clamping block, and a rubber pad is provided on one side of the clamping block.

[0009] In a preferred embodiment, the rubber pad is fixedly connected to the clamping block, and a bearing is sleeved on the outer surface of one end of the bidirectional threaded rod.

[0010] In a preferred embodiment, the bearing is placed inside the cross block, and the bearing is fixedly connected to the inner wall of the cross block and the outer surface of the bidirectional threaded rod.

[0011] In a preferred embodiment, one end of the bidirectional threaded rod is provided with a rotating block, which is fixedly connected to the bidirectional threaded rod.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] This invention, by incorporating a moving mechanism that works in conjunction with the rust-removing gun, allows operators to easily control the position of the rust-removing gun.

[0022] 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.

[0023] Example 1

[0024] like Figures 1-5 As shown, this utility model provides a technical solution: a surface oxidation treatment device for lost foam casting molds, comprising: a laser rust removal machine 1, a moving mechanism 2 provided on one side of the laser rust removal machine 1, the moving mechanism 2 including a fixed frame 21, a sliding groove 22 provided on the fixed frame 21, a sliding rod 23 provided on the inner side of the fixed frame 21, a T-shaped limiting groove 24 provided inside the sliding rod 23, and fixed rods 25 sleeved inside both the sliding groove 22 and the T-shaped limiting groove 24, the number of fixed rods 25 being three, of which two fixed rods 25 are fixedly connected to the sliding rod 23, and the outer surface of the fixed rods 25 is sleeved with There is a roller 26, which is rotatably connected to the fixed rod 25. An auxiliary mechanism 3 is provided on one side of the sliding rod 23. The auxiliary mechanism 3 includes a horizontal block 31. A bidirectional threaded rod 32 is sleeved inside the horizontal block 31. A threaded frame 33 is sleeved on the outer surface of the bidirectional threaded rod 32. The threaded frame 33 is threadedly connected to the bidirectional threaded rod 32. A clamping block 34 is provided on one side of the threaded frame 33. A limit ring 27 is sleeved on the outer surface of one end of the fixed rod 25. The limit ring 27 is fixedly connected to the fixed rod 25. An embedded block 28 is sleeved inside the sliding rod 23. The embedded block 28 is fixedly connected to the fixed rod 25.

[0025] In this embodiment, a fixed frame 21 with a certain height is provided, allowing the lost foam mold to be placed at the bottom inner side of the fixed frame 21. This enables the rust removal gun to remove rust stains from the mold surface. A sliding rod 23 is provided, which can reciprocate, allowing the rust removal gun to be positioned closer to the desired location. An embedded block 28 is also provided, which can slide inside the sliding rod 23 and drive the auxiliary mechanism 3 to reciprocate. This allows the auxiliary mechanism 3 to work in conjunction with the sliding rod 23 to accurately adjust the position of the rust removal gun, enabling the rust removal gun to remove rust from the entire surface of the mold. A fixed rod 25 is provided, which can drive the roller 26 to slide inside the groove 22 and the sliding rod 23. Since the roller 26 can rotate around the fixed rod 25, the sliding rod 23 and the embedded block 28 can be adjusted more easily.

[0026] Example 2

[0027] like Figures 1-5 As shown, the horizontal block 31 is fixedly connected to the embedded block 28, the threaded bracket 33 is sleeved inside the horizontal block 31, the threaded bracket 33 is slidably connected to the horizontal block 31, the threaded bracket 33 is fixedly connected to the clamping block 34, one side of the clamping block 34 is provided with a rubber pad 35, the rubber pad 35 is fixedly connected to the clamping block 34, one end of the bidirectional threaded rod 32 is sleeved with a bearing 36, the bearing 36 is placed inside the horizontal block 31, the bearing 36 is fixedly connected to the inner wall of the horizontal block 31 and the outer surface of the bidirectional threaded rod 32, one end of the bidirectional threaded rod 32 is provided with a rotating block 37, the rotating block 37 is fixedly connected to the bidirectional threaded rod 32.

[0028] In this embodiment, by setting an auxiliary mechanism 3, which can clamp and fix the rust removal gun, the rust removal gun can remain stable during use. A bidirectional threaded rod 32 is set, which can drive two threaded brackets 33. Thus, the two threaded brackets 33 can drive the clamping blocks 34 fixedly connected to them to move simultaneously in opposite directions, so that the clamping blocks 34 can firmly clamp and fix the rust removal gun under the action of the rubber pad 35.

[0029] Working principle:

[0030] like Figures 1-5As shown, in use, the rust removal gun of the laser rust removal machine 1 can be fixed first. At this time, the rust removal gun is placed inside the two rows of clamping blocks 34 in a suitable position. Then, the rotating block 37 is rotated, which drives the bidirectional threaded rod 32 to rotate. The bidirectional threaded rod 32, with the cooperation of the bearing 36, can drive the two threaded frames 33. Thus, the threaded frames 33 can drive the two rows of clamping blocks 34 to move closer to the rust removal gun at the same time. The clamping blocks 34 can squeeze the rubber pad 35 and deform it. Then, under the action of the rubber pad 35, the clamping blocks 34... The rust removal gun can be tightly clamped and fixed. Then, the lost foam mold is placed at the bottom of the fixed frame 21, and the laser rust removal machine 1 is started. At this time, the rust removal gun is controlled and moved. The rust removal gun can remove the rust stains on the outer surface of the mold. When the rust removal gun moves, it will drive the embedded block 28 to slide inside the sliding rod 23. When the embedded block 28 and the sliding rod 23 move, they can both use the fixed rod 25 to drive the roller 26 to rotate and move in the sliding groove 22 opened on the fixed frame 21 and the T-shaped limiting groove 24 opened in the sliding rod 23. Thus, the movement of the rust removal gun can be more convenient.

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.
