Flexible pure aluminum foil and glass fiber composite material machining mold

Abstract

The invention relates to a flexible pure aluminum foil and glass fiber composite material machining mold. The mold comprises an etching mask, a first aluminum block and a second aluminum block. The etching mask and the first aluminum block are fixed through locating PINs; two kidney-shaped holes which are distributed side by side are formed in the etching mask; blades are embedded into the peripheries of the kidney-shaped holes; a first groove which is used for embedding the locating PINs and positioning pins is formed in the first aluminum block; a supporting seat is disposed at the bottom ofthe first groove; a second groove which is used for embedding the locating PINs and the positioning pins is formed in the second aluminum block; the outer walls of the locating PINs are sleeved withsprings; and the locating PINs and the positioning pins are inserted into the first groove and the second groove in sequence, and the second aluminum block is embedded into the first groove so as to be fixedly connected. By means of the flexible pure aluminum foil and glass fiber composite material machining mold, the effect that the slope of the periphery of a punched opening of a product is uniform is guaranteed, and the slope of the periphery is smaller than or equal to 0.1 mm.

Description

technical field [0001] The invention relates to the field of die-cutting processing, in particular to a processing die for soft pure aluminum foil and glass fiber composite materials. Background technique [0002] figure 1 A schematic diagram of the composite material. Such as figure 1 As shown, in the voice control module, composite materials are often used, that is, the two surfaces of a layer of foam are respectively bonded with soft pure aluminum foil coated with a metal conductive layer, which is used to reduce the conductive resistance of the contact surface and resist corrosion. Connector assembly metallization compatibility. [0003] The design length a of the product is 16.0790mm±0.025mm, the design width b of the product is 5.5900mm±0.025mm, the edge of the product is chamfered, and the edge of the product is marked with a 4-R2 processing line. The cutting surface of the product is required to be ≤0.01mm. Customers have extremely strict requirements on the fla...

AI Technical Summary

Problems solved by technology

[0006] Deficiencies in the prior art: in the punching process, due to the extrusion around the edge of the die, the sponge is relatively soft and cannot withstand the extrusion force around the product, so the extrusion deformation around the product is relatively large, and the gradient often occurs. Tolerance phenomenon

Inspectors cannot detect defective products, resulting in inflow to clients

Therefore, the existing technology can only slightly alleviate the problem, and cannot achieve good results.
