Abstract
Urge amine curing the invention discloses a kind of cold-box core blower molding sand, including matched moulds, vacuumize, inflate, being vented, air guide, purification style, die sinking are carried out.The inventive method is on the basis of conventional method, add recovery method, by recycling step, the Triethylamine gas that can will have imported catalysis are reclaimed, then in order to avoid remaining gas is released, later stage is absorbed corresponding gas importing clarifier, it is possible to decrease the consumption of clarifier inside cleanser, reduces cost recovery.
Description
Technical field
The present invention relates to molding sand casting field, more particularly to a kind of cold-box core blower molding sand urges amine curing.
Background technology
In foundry machinery field, cold core machine core-making technique is widely used efficient core-making technique, cold core mechanism core side
Method is that the resin sand being blended is injected in mould, and it is solidified by being blown into triethylamine.In chemically reacting herein, due to three second
Amine is only used as catalyzed gas, and a large amount of compositions will not be produced to be lost.Because triethylamine is toxic gas, traditional mode of production is general
All Triethylamine gas are passed directly on cold core machine mould, and the three of discharge is absorbed in mould other end connection device for absorbing tail gas
Ethamine；It is undoubtedly a large amount of that triethylamines are lost；In addition, being completed by need to only contacting triethylamine based on molding sand coremaking reaction, it is not necessary to it is required that
Triethylamine gas are largely rested in reactor.
It is general to be introduced directly into mould inside using by triethylamine in traditional catalytic way, clarifier is directly connected afterwards
Triethylamine gas are catalyzed, but the catalytic way can typically be lost substantial amounts of triethylamine after-purification agent, undoubtedly waste of resource.
The content of the invention
The technical problem to be solved in the present invention is：For above-mentioned the deficiencies in the prior art, there is provided a kind of cold-box core blower
Molding sand urges amine curing.
The present invention solve its technical problem solution be：A kind of cold-box core blower molding sand urges amine curing, its
It is characterised by, comprises the following steps：
（1）After core shooter penetrates sand, molding sand mold and lower mould are carried out into matched moulds treatment, obtain in fill molding sand mould；
（2）By step（1）Molding sand mould is filled in described and connects vacuum tank A, open the valve A on vacuum tank A, reduced in mould
Portion's air pressure；
（3）Close step（2）Described valve A, by step（2）Molding sand mould is filled in described and connects triethylamine tank B, open three
Valve B on ethamine tank B, mould inside is imported by triethylamine；
（4）Normal temperature stands, and closes valve B, after mould is connected into vacuum tank C, the valve C on vacuum tank C is opened, by mould inside
Triethylamine is derived to vacuum tank C；
（5）Close step（4）Described valve C, air tank D is connected by mould one end, and the other end connects clarifier E, opens empty
Gas tank D, by remaining triethylamine derivation mould in mould to clarifier E；
（6）All valves are closed, upper and lower mould is opened.
As one of preferred technical scheme, it is characterised in that described step（4）The time that middle normal temperature stands is 0.1
- 600 seconds.
As one of preferred technical scheme, it is characterised in that described step（5）In clarifier inside by being provided with
Phosphoric acid solution.
The beneficial effects of the invention are as follows：The inventive method adds recovery method on the basis of conventional method, by returning
Step is received, the Triethylamine gas that can will have imported catalysis are reclaimed, then in order to avoid remaining gas is released, the later stage is by phase
Answer gas to import clarifier to be absorbed, it is possible to decrease the consumption of clarifier inside cleanser, reduce cost recovery.
