Description
Technical field
A kind of mold cooling pipe wall incrustation scale stripping off device of the present invention is related to one kind during mold dimension is supported, to mold
Cooling line in module carries out the device of incrustation scale stripping, belongs to mold dimension and supports field.More particularly to one kind can be along
Gradually deeply, the device removed to duct wall incrustation scale is rinsed in cooperation double helix gap to cooling line.
Background technology
Currently, during machinery production, many products are molded using Mold Making, such as plastic products mostly use injection molding
Mold, blow mold；Metal material is using the moldings such as die casting, in order to ensure mobility when due to molding, mold need into
Row die temperance control cools down high temperature dot generally use cooling system, by built-in waterway circulating, gradually into trip temperature
Control, in use, the water in cooling water channel and pipeline contact, as the temperature increases so that water quality is produced in tube wall
It scales, influences the throughput of cooling water, reduce temperature exchange efficiency, cause mold local temperature excessively high, it is therefore desirable to is fixed
Phase carries out cleaning dredging to cooling water channel, and existing clean method is all to carry out immersion cleaning using chemical reagent, and weak acid is put
Enter in cooling water channel, cooling water channel is impregnated, impact cleaning is then carried out by high pressure, incrustation scale is passed in and out and is cleaned, but mould
Water route in block is crisscross, when carrying out high-pressure wash, it is easy to be accumulated in pipeline crossover location so that cleaning is not thorough
Bottom, and weak acid soaking time is long, after water pipe is blocked, acid solution can not circulate, and high-pressure wash can not be by the water of bulk
Dirt washes away, and bulk incrustation scale can be not thorough in clamping stagnation, cleaning in water pipe, inefficiency,
Publication number CN203246027U discloses a kind of injection mold water route automatic cleaning apparatus, including injection mold, connection water
Pipe, corrosion protection pump, cleaning liquid pool, cleaning solution, injection mold are connect by water pipe with cleaning liquid pool, and cleaning liquid pool is by water pipe and prevents
Corruption pump connection, corrosion protection pump connect injection mold by water pipe and connect, and cleaning solution are equipped in cleaning liquid pool, by by cleaning solution and mould
Tool water route connects to form circulation path, is cleaned to die waterway, and this method efficiency is low, needs by ceaselessly recycling, when
Water route occurs after blocking, and is hardly formed cycle, cleaning effect is poor.
Invention content
In order to improve the above situation, a kind of mold cooling pipe wall incrustation scale stripping off device of the present invention provides one kind being capable of edge
It cooling line gradually to go deep into, the device for removing duct wall incrustation scale is rinsed in cooperation double helix gap.
