Embodiment 1

[0038] Reference attached Figure 1-4 , a mold for forming an elliptical spherical hollow mesh metal sound grille, comprising a lower mold base 001, the lower mold base 001 is fixed with a lower mold 002, and the lower mold 002 is formed with an elliptical sphere hollow The mesh metal sound grille (not shown in the drawings) is structurally matched to the molding cavity 003. The upper end of the lower mold 002 is provided with an elastic rubber upper mold core 004 that can be movably implanted into the molding cavity 003. The upper end of the elastic rubber The mold core 004 is provided with a pressure bar 005 that can drive the elastic rubber upper mold core 004 to move and / or squeeze the elastic rubber upper mold core 004 to expand. The upper end of the upper die 006 is provided with an upper die base 007. In practice, the upper die base 007 is connected to the punching machine and can be moved by the punching machine, while the lower die base 001 and lower die 002 are fixed...

Embodiment 2

[0041] Reference attached Figure 4, a method for forming an ellipsoidal hollow mesh metal sound grill, comprising the following steps:

[0042] Step S21. Cropping

[0043] Use a punch to cut the metal blank into a sheet-shaped blank to be formed;

[0044] Step S22. Etching

[0045] ⅰ. Cleaning: Utilize an ultrasonic cleaning machine to cooperate with a cleaning solution to clean the cut sheet-shaped blank to be formed, and remove the oil stain on its surface;

[0046] ⅱ. Pre-etching treatment: apply photosensitive ink, pre-drying, exposure and development to the sheet-shaped blank to be formed in sequence;

[0047] ⅲ. Etching hollow mesh holes: transport the pre-etched sheet blank to the chemical etching machine, and match the chemical etching solution to etch and form hollow mesh holes of matching shape and number on the sheet blank to be formed. hole;

[0048] ⅳ. Post-etching treatment: immerse the sheet blank to be formed with the hollow mesh hole etched in the deinki...

Abstract

The invention discloses a die for molding an elliptical spherical hollow net-type metal sound equipment mesh enclosure. The die comprises a lower die base. A lower die is fixedly arranged on the lowerdie base. A molding cavity matched with the elliptical spherical hollow net-type metal sound equipment mesh enclosure in structure is formed in the lower die. The upper end of the lower die is provided with an elastic rubber upper die insert capable of being movably implanted into the molding cavity. The elastic rubber upper die insert is provided with a pressure lever capable of driving the elastic rubber upper die insert to move and / or extruding the elastic rubber upper die insert to swell. The upper end of the pressure lever is provided with an upper die fixedly connected with the pressurelever. The upper end of the upper die is provided with an upper die base. In the molding process, the sound equipment mesh enclosure to be molded is arranged on the elastic rubber upper die insert ina sleeving mode and is carried by the elastic rubber upper die insert to be implanted into the molding cavity from top to bottom. The upper die vertically moves downwards to enable the pressure leverto vertically downwards extrude the elastic rubber upper die insert. The elastic rubber upper die is extruded to swell and extrudes the sound equipment mesh enclosure outwards to cooperate with the molding cavity of the lower die to complete molding of the elliptical spherical hollow net-type metal sound equipment mesh enclosure.

Description

technical field [0001] The invention relates to the field of metal material shaping, in particular to a mold and a method for forming an ellipsoid hollow mesh metal sound grill. Background technique [0002] In the existing technical field of metal material processing, due to the advantages of low stamping process cost and stable stamping mold after forming, it is used in the stamping and forming process of various metal material shells. However, the existing stamping dies can usually only process products with relatively regular shapes such as cuboids and cylinders, and for ellipsoids (refer to attached figure 1 ) shape cannot be processed and produced directly through the stamping process. In order to meet the customer's demand for structural diversity without increasing costs, the creator of this work designed a mold and method for forming an elliptical spherical hollow mesh metal audio grille. The ellipse can be completed by stamping technology. , Processing of spheric...
