The forming process 'hardware' of the progressive die of precision stamping parts

The structural characteristics of the progressive die for precision stamping parts: 1. The mold is composed of an upper mold, a lower mold and a mold sleeve, and is guided by a guide post; 2. The upper mold has an upper mold fixed plate with a punch and a screw on the upper mold. Template connection; 3. Two semi-conical concave molds are inserted into the concave mold sleeve with tapered holes, with cavity holes in the middle, and two semi-circular concave molds are positioned by two positioning pins; 4. The lower mold is located by The lower mold fixing plate is composed of a core and another core; 5. The unloading part is composed of ejector pins and ejector pads. After the parts are formed, the upper mold is first opened with a special mold-unloading work, and then used The ejector pin pushes the two half-cone concave molds out of the mold, and separates the progressive mold to take out the product. The forming process of the progressive die of precision stamping parts: The forming process principle of the progressive die of precision stamping parts is mainly divided into three stages. 1. In the preparation stage, after weighing the plastic powder, first pour it into the feeding chamber and heat it to a plastic state; 2. In the pressure stage, when the pressure column moves down on the worktable on the hydraulic press, it enters the feeding chamber to pressurize the molten plastic 、Inject into the cavity at high speed through the gating system of the mold, and ensure heat preservation for a certain period of time, and harden to form; 3. In the unloading stage, after the mold is opened, use a special unloading mechanism to eject the plastic part, and clean the cavity and add materials Chamber and sprue, ready to be squeezed for the next stroke.
