Description

Technical Field

[0001] The utility model relates to the technical field of clamp devices, in particular to an embedded part clamp device. Background Art

[0002] Embedded parts are embedded parts of injection molding machines. When making certain injection molded products, it is necessary to fix specific embedded parts in the mold in advance, and inject plastic into the mold during the injection process so that the plastic and embedded parts are tightly combined to achieve the specific purpose of the product. Embedding embedded parts of specific shapes in the mold before injection molding can reduce subsequent manual processing and greatly reduce the production cost of the product.

[0003] In the prior art, a clamp is required when embedding embedded parts in a mold or taking them out of a mold, and most of the existing clamps rely on a driving mechanism to drive multiple clamps to move closer or farther away at the same time, so that multiple clamps can be clamped or released at the same time. This type of clamp can clamp some regular-shaped embedded parts such as round and rectangular well, but for some irregular-shaped embedded parts, some clamps will not clamp the embedded parts after clamping, resulting in poor stability.

[0026] Among them, a first screw rod 22 is rotatably connected in the first rectangular frame 5, and the first screw rod 22 passes through the first rectangular plate 6 and is threadedly connected to the first rectangular plate 6. The top and bottom of the first rectangular plate 6 are both in contact with the top inner wall and the bottom inner wall of the first rectangular frame 5. A first servo motor 23 is installed on one side of the first rectangular frame 5, and the output end of the first servo motor 23 is fixed to the first screw rod 22. A second screw rod 24 is rotatably connected in the second rectangular frame 7, and the second screw rod 24 passes through the second rectangular plate 8 and is threadedly connected to the second rectangular plate 8.

The second servo motor 25 is started to drive the second screw 24 to rotate, thereby driving the second rectangular plate 8, the first hydraulic cylinder 9 and the clamping component to move, thereby adjusting the position of the clamping component, and the infrared sensor 4 can monitor the position of the clamping component. When the clamping component is located directly above the embedded part, the first hydraulic cylinder 9 extends to drive the clamping component to move downward, so that the clamping component clamps the embedded part.

[0028] In addition, a concave plate 11 is fixed at the bottom of the hollow plate 10, and a plurality of cylindrical tubes 12 are fixed and connected to the outer side of the concave plate 11 at equal intervals along the radial direction thereof, and an air guide tube 13 is fixed and connected to the end of the cylindrical tube 12 away from the concave plate 11, and an end of the air guide tube 13 away from the cylindrical tube 12 is fixed and connected to the hollow plate 10, and the clamping component includes a baffle 14 fixed in the cylindrical tube 12, a cylindrical rod 15 is slidably connected in the baffle 14, and a clamping plate 16 is fixed to one end of the cylindrical rod 15 located in the concave plate 11 A first piston 17 is fixed to one end of the cylindrical rod 15 located in the cylindrical tube 12, and the first piston 17 is sealed and slid in the cylindrical tube 12.
