Embodiment Construction

[0024] The present invention will be further described in detail below in conjunction with the embodiments and the accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0025] refer to Figure 1 to Figure 2 As mentioned above, the present invention provides a method for manufacturing a smooth insert of an injection mold. The smooth insert of the injection mold is prism-shaped, and the center of the upper end of the smooth insert of the injection mold is provided with a thimble hole 1, The lower end of the smooth insert of the injection mold is provided with a fixing groove 2, the outer surface of the insert is provided with a nickel-plated coating, and the upper surface of the smooth insert is provided with an arc-shaped glue surface 3. The glue surface 3 is a smooth surface processed by a high-precision optical lathe.

[0026] Specifically, the roughness of the glue plane 3 is Ra≦8nm.

[0027] Described method comprises the following...

Abstract

The invention discloses a machining method for insert polishing. The machining method comprises the several steps of CNC machine tool machining, EDM primary machining, insert coating, EDM secondary machining, linear cutting and high-precision optical lathe machining. The invention further discloses a glaze insert of an injection mold manufactured by the method. A machining process for coating by the insert is designed for optimizing the machining method to guarantee the coating binding force strength; meanwhile, an insert revolving tool fixture is designed; and the high-precision optical lathe machining is applied to realize high-polishing surface smoothness of a glue position surface, so that the smooth roughness of the insert reaches 8 nm; the workpiece polishing is not needed, the product highlight requirement is achieved in the injection molding process, the machining process is reduced, and the insert quality, precision and production efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a method for manufacturing a smooth insert of an injection mold. Background technique [0002] In the existing injection molding mold structure, when the high gloss of plastic products is required, the traditional process is to use manual polishing to achieve the high finish requirements of the product after CNC and EDM equipment processing. Due to the product's curved surface design and reflective requirements, the traditional processing process is likely to cause problems such as material deformation, ripples, orange peel, pitting, etc., which will increase many hidden costs. Contents of the invention [0003] In view of this, the purpose of the present invention is to provide a processing method for polishing inserts in injection molds, which solves the risks of traditional product polishing and can meet the high gloss requirements of products. [0004] In ord...
