Problems solved by technology

[0002] Water-soluble wax mold core is an important product in wax mold processing, especially for parts that need to use water-soluble wax. The water-soluble wax mold core is placed to form the internal structure of the part, while the existing water-soluble wax mold with a large point plane There are more pockmarks on the surface of the core, which will affect the subsequent processing

Embodiment Construction

[0008] A water-soluble wax mold forming process, adding fibers with a length of 3 mm to the wax mold raw materials, the fiber content accounts for 1.5% of the total wax mold raw materials, and then put the wax mold raw materials into the wax cylinder, heating to 70-80 ° C for chemical Wax: Stir the melted wax for 2-3 hours. After the stirring is completed, press the wax to form water-soluble wax. Cut the water-soluble wax and inject it into the mold through the wax injection nozzle to form a water-soluble wax core. The size of the wax injection nozzle is 6.5mm, and the original 4.5mm size wax injection nozzle is increased to 6.5mm, which can effectively avoid the wax mold protrusion at the wax injection nozzle due to the impact force of the wax injection, which makes the water-soluble wax mold core sink. Phenomenon.

[0009] In the original water-soluble wax mold core, the fiber length is 5mm, and the content is 1.5%. In the present invention, there is no pockmark on the surfa...

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 [0001] The invention relates to the technical field of embossed wax for complex parts, in particular to a water-soluble wax mold forming process. Background technique [0002] Water-soluble wax mold core is an important product in wax mold processing, especially for parts that need to use water-soluble wax. The water-soluble wax mold core is placed to form the internal structure of the part, while the existing water-soluble wax mold with a large point plane There are more pockmarks on the surface of the core, which will affect the subsequent processing. Contents of the invention [0003] In order to solve the above problems, the present invention provides a water-soluble wax mold forming process, the water-soluble wax mold core produced by the process has a smooth surface without pitting, which ensures the quality of subsequent processing. [0004] Its technical scheme is as follows: a water-soluble wax mold forming process, which is characterized in that ...
