Technical Field

[0001] The utility model relates to the technical field of hydraulic presses, in particular to a magnetic material dry-type forming hydraulic press with a guide structure. Background Art

[0002] Magnetic materials are a general term for materials that react in some way to the surrounding magnetic field. To ensure the performance of magnetic materials, magnetic blocks are made of metal materials such as Fe, Co, Ni, Ba, Sr, and Pb, or their compounds and sintered materials. In the application range of electromagnetic force, microphones, watches, relays, sensors, motors, etc. all require the assembly of magnetic components.

[0003] To prevent the magnetic material from dispersing, a hydraulic press is often used to press and shape it. A cylinder is used to control the plate with the upper mold to press it against the plate with the lower mold, and then the magnetic material is removed. However, in the past, the fixed and movable plates and the mold were often locked only by bolts and nuts, lacking the necessary limiting structure. This resulted in problems such as misalignment between the upper and lower molds, affecting the shaping of the finished product.

[0004] Now, a new type of magnetic material dry forming hydraulic press with a guide structure is proposed to solve the above problems. Utility Model Content

[0008] Preferably, the clamping plates are symmetrically clamped on both sides of the upper die and the lower die, and the upper part of the limiting rod is embedded in the sleeve block.

[0009] Preferably, four groups of support rods are welded to the left of the center above the base plate, and frosted tubes are sleeved above the support rods. Cross plates are welded between the tops of the frosted tubes, and springs are welded between the bottoms of the frosted tubes and the base plate.

[0010] Preferably, a rubber sleeve is fixed on the inner wall of the frosting tube, and the support rod can contact the frosting tube and slide up and down.

[0011] Preferably, the support rod is embedded in the center of the spring, and the support rod, spring and frosted tube are arranged in concentric circles.

There is no need to add materials manually. After taking out the complete magnetic material, it can be injected again. BRIEF DESCRIPTION OF THE DRAWINGS
