Description
Technical field
The present invention relates to mould manufacture field, more particularly to a kind of processing technology of high abrasion mould.
Background technology
Mould be in industrial production being molded, being blow molded, extruding, die casting or obtain the methods of forging forming, smelting, punching press
To the various moulds and instrument of required product.In brief, mould is the instrument for making formed article, this instrument by
Various parts are formed, and different moulds is made up of different parts.It mainly by the change of institute's moulding material physical state come
Realize the processing of article profile.It is known as the title of " mother of industry ".
Mould is blank is turned into the instrument for having given shape and the product of size under external force.It is widely used in punching
Sanction, die forging, cold-heading, extruding, metallic sintered products compacting, compression casting, and the compression moulding of the product such as engineering plastics, rubber, ceramics
Or in the forming of injection.
Mould has specific profile or cavity shape, can make blank by contour line using the contour shape with cutting edge
Separation (punching) occurs for shape.Using cavity shape blank can be made to obtain corresponding three-dimensional shape.Mould generally comprise dynamic model and
Cover half（Or punch-pin and cavity plate）Two parts, the two is partable.Product is taken out when separating, blank is injected mould type when closing up
Chamber shapes.Mould is precision instrument, complex-shaped, bears the expansive force of blank, thick to structural strength, rigidity, case hardness, surface
Rugosity and machining accuracy all have higher requirements.
Existing mould makes product keep dimensional accuracy and table due to produce friction strong many times with workpiece
Surface roughness is it is necessary to have high intensity, high rigidity and excellent wearability, generally by the addition wear-resistant component in material
Obtain, the mould that this mode obtains can not keep permanent abrasion resistant effect, can not meet the requirement of long-term use.
