Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0031] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 This utility model provides a magnetic material processing and forming device, including a base 1, a stationary groove mold 5, a moving groove mold 4, a groove bottom plate 9, a push plate 63, a first driving device 3, a second driving device 7, and a punch 10.

[0032] A linear slide rail 2 is mounted on the base 1. A stationary groove mold 5 is fixedly mounted on the base 1. The stationary groove mold 5 has a first groove notch, and a push plate 63 is positioned on the side of the first groove notch facing the moving groove mold 4. The moving groove mold 4 is slidably mounted on the linear slide rail 2 and arranged opposite to the stationary groove mold 5. The moving groove mold 4 has a second groove notch corresponding to the first groove notch. A groove bottom plate 9 is detachably mounted on the base 1 and located below the stationary groove mold 5 and the moving groove mold 4. A stepped platform is provided at the bottom of the stationary groove mold 5 and the moving groove mold 4. A flat insertion port is formed at the stepped platform behind the stationary groove mold 5 and the moving groove mold 4, and the groove bottom plate 9 is positioned within this insertion port.

[0033] The first driving device 3 is connected to the moving groove mold 4 and is used to drive the moving groove mold 4 to slide along the linear slide rail 2 toward or away from the stationary groove mold 5, so that the first groove notch and the second groove notch close or separate from each other. When they close, the push plate 63, the groove bottom plate 9 and the two groove notches together form a pressing groove 14 with the groove opening facing upwards. Figure 3 As shown. The second driving device 7 is located above the base 1; the punch 10 is connected to the second driving device 7, and the bottom of the punch 10 is provided with a protrusion 13 corresponding to the pressing groove 14. The protrusion 13 is pressed into or out of the pressing groove 14 by the second driving device 7. When the moving groove mold 4 separates from the stationary groove mold 5, the push plate 63 moves with the moving groove mold 4, pushing the formed material out of the pressing groove 14, as shown. Figure 4 As shown.

[0034] When in use, this device utilizes the complementary notch design of the stationary groove mold 5 and the moving groove mold 4. During mold closing, the push plate 63 and the groove bottom plate 9 together form the pressing groove 14, and the protrusion 13 of the punch 10 is pressed in, thus achieving precise molding of magnetic powder materials. During demolding, the moving groove mold 4 retracts, directly driving the push plate 63 to push out the blank synchronously. The mold closing and demolding actions are integrated into a single linear motion system, which simplifies the mold structure and avoids the damage to the blank caused by the separation of the traditional ejection mechanism from the mold.

[0035] In an optional embodiment of this utility model, the device further includes a push-pull shaft 61 and a connecting frame 62, which together with the push plate 63 constitute the mold auxiliary assembly 6. The push-pull shaft 61 is parallel to the linear slide rail 2, passes through and is clearance-fitted into the stationary groove mold 5, and one end is connected to the moving groove mold 4 through the connecting frame 62, while the other end is connected to the push plate 63. This structure enables mechanical linkage between the moving groove mold 4 and the push plate 63. The push-pull shaft 61 passes through the stationary groove mold 5 and is indirectly connected to the moving groove mold 4, ensuring that the push plate 63 produces synchronous displacement when the moving groove mold 4 slides, thus eliminating transmission gaps.

[0036] In an optional embodiment of this utility model, the second driving device 7 is supported and mounted on the base 1 by a bracket 11; four optical axes 8 are arranged between the top of the bracket 11 and the base 1, and the optical axes 8 penetrate the punch 10 to guide the punch 10 to move up and down. The optical axes 8 penetrate the punch 10 to form four-point positioning, ensuring the coaxiality of the protrusion 13 and the pressure groove 14.

[0037] In an optional embodiment of this utility model, the first driving device 3 and the second driving device 7 are both hydraulic cylinders, and the hydraulic telescopic shaft of the first driving device 3 is arranged in a direction parallel to the optical axis 8 and connected to the punch 10, and the hydraulic telescopic shaft of the second driving device 7 is arranged in a direction parallel to the linear slide rail 2 and connected to the moving groove mold 4.

[0038] In an optional embodiment of this utility model, the base 1 is provided with a plurality of pin holes corresponding to the insertion of the positioning pin 12, the positioning pin 12 penetrates the bottom plate 9 of the groove, and the bottom plate 9 of the groove is horizontally limited by the positioning pin 12.

[0039] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
