Embodiment Construction

[0023] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0024] Such as Figures 1 to 3 As shown, according to an embodiment of the present invention, the protective device for mold polishing includes a protective plate 10, and the protective plate 10 is fixedly arranged on the mold 20 to be polished, and the mold 20 to be polished is provided with a cavity for forming an injection molded part. A hollow part corresponding in shape to the concave cavity is arranged on the top, and the side wall surface of the hollow part is aligned with the side wall surface of the concave cavity. By arranging the protective plate 10 on the mold 20 to be polished, the edge of the concave cavity of the mold to be polished 20 can be protected by the protective plate 10 in th...

Abstract

The invention provides a mold polishing protection device and a mold polishing method. The mold polishing protection device comprises a protecting plate, the protecting plate is fixedly arranged on a mold to be polished, the mold to be polished is provided with a cavity for forming injection-molded pieces, the protecting plate is provided with a hollow-out part corresponding to the cavity, and the side wall surface of the hollow-out part is aligned to the side wall surface of the cavity. The protecting plate can avoid corner collapse of the mold to be polished and accordingly improve the mold yield rate.

Description

technical field [0001] The invention relates to the field of mold processing, in particular to a protection device for mold polishing and a mold polishing method. Background technique [0002] The inner cavity of the processing mold for the appearance parts has always been polished by the traditional polishing process, and these polishing operations are very likely to cause deformations such as gaps or collapses in the parting mouth of the inner cavity of the mold, so that the compression of the two molds There are gaps in the joint, resulting in convex edges in the shape of the processed product, which not only affects the appearance of the product, but also reduces the touch feel of the product. The existing polishing method is very easy to cause the slump angle of the fixed and movable parting mouth of the mold, which will cause faults or convex edges in the appearance of the product, which will affect the appearance effect. It is difficult to protect and the polishing e...
