Abstract

The invention relates to a cleaning auxiliary device, a cleaning method and a shielding piece. The cleaning auxiliary device comprises a shielding piece and a fixing assembly. The shielding piece covers a mold closing contact surface between the molds; the shielding piece comprises an inner contour formed in a hollowed-out mode, and the shape of the inner contour is matched with the shape of a mold cavity contour. And the fixing assembly is arranged on the shielding piece and used for being connected with the mold. The shielding piece is connected to the mold through the fixing assembly and covers the mold closing contact surface between the molds, so that the shielding piece protects the mold closing contact surface at the joint part in the process that the joint part in the shape of a sharp corner between the mold closing contact surface and the mold cavity contour surface is impacted by cleaning particles or cleaning liquid, and the mold closing contact surface is prevented from being damaged. The cleaning impact only acts on the surface of one side of the combination part, namely the profile surface of the cavity, so that the situation that the sharp-corner-shaped combination part is subjected to yield deformation or sharp-corner breakage caused by double-side impact is effectively avoided, the sharp-corner shape of the combination part can be kept, and the forming precision of the mold is improved.
