Description

A kind of combined die for forming of Grinder

Technical field

The utility model relates to a kind of mould, specifically refers to a kind of combined die for forming of Grinder.

Background technology

In anchoring agent diamond grinding wheel manufacturing process, abrading block is compressing, first in mould, abrasive material is injected, then abrading block is obtained by the processing of abrasive wheel forming hydraulic press, abrasive wheel forming hydraulic press is to the extruding great efforts of mould, very strong to the impulsive force of mould, the inner surface of mould smooth becomes uneven, so often produce several abrading block just need more mold exchange originally.Traditional mould is all that integrally casting is shaping, safeguards cumbersome, and the mould overwhelming majority of damage needs to abandon, and mould utilization rate is low, and production cost is large.

Summary of the invention

For the problems referred to above, the utility model is the combined die for forming providing a kind of Grinder, has easy disassembly combination, the features such as easy replacing.

The technical solution adopted in the utility model is: a kind of combined die for forming of Grinder, comprise left die body, right die body, die-cushion, stamping and tight loop, described left die body and right die body surround a rectangle die cavity by tight loop, described die-cushion is positioned at mold cavity bottoms, and described stamping is positioned at mould intracavity wall surrounding.

Described left die body and right die body inner surface both sides are all provided with groove.

Described die-cushion cross-sectional sizes is consistent with die cavity.

Described stamping has 4 pieces, and stamping surface is provided with tongue.

The beneficial effects of the utility model are: after burn failure, only need to change stamping, do not need to change whole mould, have therefore saved production cost, improve stock utilization.

Fig. 2 is the schematic diagram of mill pad.

Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, but be not limited to the following stated.

A kind of combined die for forming of Grinder, comprise left die body 3, right die body 5, die-cushion 6, stamping 1, die cavity 2 and tight loop 4, left die body 3 and right die body 5 surround a rectangle die cavity 2 by tight loop 4, die-cushion 6 is positioned at bottom die cavity 2, stamping 1 is positioned at die cavity 2 inwall surrounding, and stamping 1 is nested with left die body 3 and right die body 5 respectively by tongue and groove.

After having combined, inside die cavity, pour raw material into, carry out extruding obtain abrading block by abrasive wheel forming hydraulic press, only need after mould intracavity wall damages to change mill punching, other component can normally use.
