Description
Technical field
The present invention relates to casting mould field, in particular it relates to lost wax casting mould.
Background technology
Model casting is also known as lost-wax casting, including presses wax, repair wax, group tree, be stained with slurry, dewaxing, casting metals liquid and post processing
Etc. process.Lost-wax casting is that the wax-pattern of part is cast with waxed work, mud is then coated with wax-pattern, here it is mud mould.Mud
After mould dries, then it is fired into Tao Mo.One is fired, and all fusing is lost in wax-pattern, only surplus Tao Mo.It is left with during general mud mould processed
Sprue gate, then molten metal is poured into from sprue gate, after cooling, required part is just made.Pressure handle is used in production mostly
The method manufacture fusible pattern of pasty state mould material press-in die mould.Before fusible pattern injection, need first die mould surface apply thin layer parting compound, so as to from
Fusible pattern is taken out in die mould.When suppressing cerul mould material, parting compound can be machine oil, turpentine oil etc.；When suppressing resin basic mode material, fiber crops are commonly used
The mixed liquor or silicone oil of oil and alcohol make parting compound.Parting agent gets over Bao Yuehao, fusible pattern is preferably replicated the surface of die mould,
Improve the surface smoothness of fusible pattern.But no matter with what material manufacture die mould, it is required for the processing of complexity.This brings for work
Many is constant, also increases production cost.
It therefore it provides one kind can divide mould, and can well close, make obtained wax-pattern that there is good any surface finish
Degree, and it is simple to operate, it is degradable, it is environmentally friendly to spend the problem of high lost wax casting mould is urgent need to resolve of the present invention.
The content of the invention
For above-mentioned prior art, it is an object of the invention to overcome lost-wax casting in the prior art be generally required for by
The problem of complex processing, inconvenience being brought to production, and improving production cost, it can divide so as to provide one kind
Mould, and can close well, make obtained wax-pattern that there is good surface smoothness, and it is simple to operate, it is degradable, to environment friend
High lost wax casting mould is spent well.
To achieve these goals, the invention provides a kind of lost wax casting mould, wherein, the lost wax casting mould bag
