Description
Technical field
The present invention relates to a kind of casting mould restorative procedure, belong to Materials Processing Engineering technical field.
Background technology
After the wooden, aluminum used in foundry technology process and steel casting mould through a long time use, it can all send out
Phenomena such as raw surface abrasion, mould local damage.It is typically for the restorative procedure that damaged casting mould use occurs at present
Its repair process is completed after wear surface and damaged part are filled and polished with atomic lime putty, due to atomic lime putty
The hardness of material is not high, and atomic lime putty has shrinkage phenomenon in the drying process, so as to cause the mould part being repaired
Intensity and wearability it is not high, contraction crack can be also produced, so that influencing the repair efficiency of mould and the service life of mould.
The content of the invention
The technical problems to be solved by the invention are：A kind of casting mould restorative procedure of various materials, the reparation are provided
The rehabilitation cost of method is low, and the cycle is short, and technique is simple, and the intensity and wearability for the casting mould repaired are high, surface smoothness
Height, does not produce contraction crack.
A kind of casting mould restorative procedure, it is characterised in that using following steps：
1) the wooden, aluminum repaired to needs or the position to be repaired of steel casting mould are cleared up, and use wipes of alcohol
Wipe clean；
2) specific restorative procedure is selected according to the spot size size to be repaired of casting mould after cleaning：When position to be repaired
When full-size is not less than 10mm, first carried out with backing layer repair materials it is pre-filled, after backsheet hardening after repaired again with surface layer
Material is coated reparation；Otherwise, directly reparation is coated with surface layer repair materials；
3) repair layer of the casting mould after coating is repaired by hand repaired by electric grinding polissoir, makes reparation
The size of layer reaches the size requirement of casting mould, and the surface of repair layer is polished smooth and smooth is not less than to roughness
0.8Ra grades, that is, complete the reparation of casting mould.
The casting mould restorative procedure, in step 2) composition of backing layer repair materials be epoxy resin, curing agent, increasing
Tough dose and alkali-free glass fibre chopped strand, mass ratio 100:34:11:100~180, wherein curing agent uses modified multicomponent
Amine, toughener use dibutyl phthalate, and the specification of alkali-free glass fibre chopped strand is 6mm；When pre-filled, by more than
The backing layer repair materials that four kinds of raw materials are uniformly mixed be filled into casting mould need repair position, tamping be allowed to smooth, and away from
Die surface leaves 2~3mm depressions and is used to fill surface layer repair materials later as the space repaired in advance.
The casting mould restorative procedure, in step 2) composition of surface layer repair materials be epoxy resin, curing agent, increasing
Tough dose and granularity are the wear-resisting powder of 280~400 purposes, mass ratio 100:34:11:218, wherein curing agent uses modified multicomponent
Amine, toughener use dibutyl phthalate, and wear-resisting powder is by silicon carbide powder of the weight ratio for 140 parts and 70 parts of oxidation
Aluminium powder mixing composition.
Compared with prior art, the present invention its advantage is：
1st, casting mould is repaired for the repair materials of basis using epoxy resin, with traditional using former
Sub- spachtling is compared as the method for repair materials, has the intensity height for the casting mould repaired, wearability is good, surface smoothness
The advantages of high (surface roughness is not less than 0.8Ra grades), die life is long and does not produce contraction crack.
2nd, technique is simple, and rehabilitation cost is relatively low, and repairing efficiency is short, is suitably adapted for wooden, aluminum or the various materials of steel
Casting mould reparation demand.
3rd, the present invention employs different restorative procedures for the size at the position for needing to repair, for needing to repair
The larger mould of spot size, by first with backing layer repair materials carry out it is pre-filled after be coated repair with surface layer repair materials again
It is multiple, since the toughness of backing layer repair materials is preferable, so the brittleness for avoiding the simply mould with surface layer repair materials reparation is big
Deficiency, improve the performance of mould.
Embodiment
Embodiment one, the reparation to wooden casting mould, comprises the following steps that：
