Abstract
The invention relates to the technical field of complex part wax injection, in particular to a water-soluble wax mold forming technology. The surface of a produced water-soluble wax mold core is smooth and free of pocking, subsequent processing quality is guaranteed, fibers with the length equal to 3 mm are added to the wax mold raw materials, the fibers account for 1.5% of the total quantity of the wax mold raw materials, the wax mold raw materials are put into a wax vat and heated to 70-80 DEG C for wax melting, melt wax is stirred, the stirring time is 2-3 h, wax injection is conducted after stirring is completed, water-soluble wax is formed, blanking of the water-soluble wax is conducted, and the water-soluble wax mold core is formed by injecting the water-soluble wax into a mold through a wax injection nozzle.
Description
Technical field
The present invention relates to complex parts pressure wax technical field, be specially a kind of water-soluble shaping investment pattern technique.
Background technology
Water-soluble wax-pattern core is product important in wax-pattern processing, particularly be used in the part needing to use water-soluble wax, water-soluble wax-pattern core is positioned over for forming part internal structure, and the water-soluble wax-pattern wicking surface with a little bigger plane of existing use has many pits, bring impact to following process.
Summary of the invention
In order to solve the problem, the invention provides a kind of water-soluble shaping investment pattern technique, its water-soluble wax-pattern wicking surface produced is smooth without pit, ensures following process quality.
Its technical scheme is such: a kind of water-soluble shaping investment pattern technique, it is characterized in that, in wax-pattern raw material, add the fiber of length 3mm, fiber content accounts for 1.5% of wax-pattern raw material total amount, then wax-pattern raw material is put into wax cylinder, be heated to 70-80 DEG C of carrying out wax, stir the wax of fusing, mixing time is 2-3h, carries out pressure wax and form water-soluble wax after having stirred, by water-soluble wax blanking, inject in mould form water-soluble wax-pattern core by penetrating hawfinch.
It is further characterized in that, wax-pattern raw material is put into two wax cylinders, and the carrying out wax in a wax cylinder and stirring carry out pressure wax in another wax cylinder, and the wax cylinder that pressure wax completes carries out blanking and prepares next material loading, and the wax cylinder stirred carries out pressure wax;
Penetrate hawfinch and be of a size of 6.5mm.
After adopting present invention process, owing to have adjusted length and the content of fiber in wax-pattern raw material, and stir, can not produce white fiber and pile up, the water-soluble wax-pattern wicking surface produced is smooth without pit, ensure that following process quality.
Detailed description of the invention
A kind of water-soluble shaping investment pattern technique, the fiber of length 3mm is added in wax-pattern raw material, fiber content accounts for 1.5% of wax-pattern raw material total amount, then wax-pattern raw material is put into wax cylinder, be heated to 70-80 DEG C of carrying out wax, the wax of fusing is stirred, mixing time is 2-3h, carry out pressure wax after stirring completes and form water-soluble wax, by water-soluble wax blanking, inject in mould form water-soluble wax-pattern core by penetrating hawfinch.Penetrate hawfinch and be of a size of 6.5mm, the hawfinch of penetrating of original 4.5mm size is enlarged to 6.5mm, effectively can avoid the impulsive force because penetrating wax that water-soluble wax-pattern core is caved in and cause and penetrate the protruding phenomenon of hawfinch place wax-pattern.
In original water-soluble wax-pattern core, fibre length is 5mm, and content is 1.5%, has when adopting specific experiment to verify that fibre length and content are how many surperficial without pit in the present invention in specific implementation process:
Fibre length is 5mm, and content changes 0.4%, 0.6%, 0.8%, 1.0%, 1.5%, 2.0% respectively into and verifies, result draws, the effect of above 6 kinds of different contents is all undesirable, and water-soluble wax-pattern wicking surface all has pit;
Fibre length is 6mm, and content changes 0.4%, 0.6%, 0.8%, 1.0%, 1.5%, 2.0% respectively into and verifies, result draws, the effect of above 6 kinds of different contents is all undesirable, and water-soluble wax-pattern wicking surface all has pit;
Fibre length is 4mm, and content changes 0.4%, 0.6%, 0.8%, 1.0%, 1.5%, 2.0% respectively into and verifies, result draws, the effect of above 6 kinds of different contents is all undesirable, and water-soluble wax-pattern wicking surface all has pit;
Fibre length is 3mm, and content changes 0.4%, 0.6%, 0.8%, 1.0%, 1.5%, 2.0% respectively into and verifies, result draws, removing fiber content is the smooth surface of 1.5%, without pit, the effect of all the other 5 kinds of different contents is all undesirable, and water-soluble wax-pattern wicking surface all has pit.
The present invention can adopt two cylinders to operate in stirring, pressure wax process, raise the efficiency, concrete operations are as follows: wax-pattern raw material is put into two wax cylinders, carrying out wax in a wax cylinder and stirring, pressure wax is carried out in another wax cylinder, the wax cylinder that pressure wax completes carries out blanking and prepares next material loading, and the wax cylinder stirred switches and carries out pressure wax.
Claims (3)
