Novel metal rubber material pressing mould

Abstract

The invention discloses a novel metal rubber material pressing mould. The novel metal rubber material pressing mould comprises a compression device and a base part. The compression device comprise a compression bar guide shell, U-shaped ball bearings, a male die base and an upper compression bar; and the base part comprises a guide base and a vacuole leveling instrument. The ball bearings are installed on the compression bar guide shell in the annular direction; and four groups of the ball bearings are installed in the annular direction, and each group has three ball bearings. An upper pressing mould body is placed in the compression bar guide shell, and protruded tracks on the compression bar are matched with the U-shaped ball bearings. A protruded part of the male die base is inserted into the upper compression bar, and the compression bar guide shell is inserted into a groove of the male die. The male die and the guide base of the base part are connected through a cross-shaped shaft. According to the novel metal rubber material pressing mould, stuck phenomenon in a pressing process can be remarkably improved, so that the cost is reduced, and the trouble of replacing the mould is saved; main pressing objects of the novel metal rubber material pressing mould are metal rubbers with through holes; manufacturing cost of the mould is low; and the volume is smaller and the mould is more portable.

Description

technical field [0001] The invention relates to a mold, in particular to a novel mold for pressing metal rubber materials, and belongs to the technical field of metal rubber pressing mold structures. Background technique [0002] Metal rubber is a network structure made of interlaced metal wires, and its performance is similar to that of rubber polymer materials. The preparation process is to stretch a certain quality metal mesh, then extrude the required size of the lines, and put them into the mold in an orderly manner according to the shape of the processed test piece for compression molding. The more common molds currently used include an upper pressing plate, a lower punch, a metal rod, two pressing rods and a sleeve. Its disadvantages are obvious: it is easy to get the metal rubber of the desired shape or get stuck due to the uneven placement of the metal mesh in the mold or the insufficient level of the pressure tool in the universal testing machine, which in turn le...
