Description
Technical field
The invention belongs to die casting field, it is specifically related to a kind of by release agent recovery method used in press casting procedure and return
Receiving apparatus.
Background technique
Release agent is a kind of functional materials between mold and finished product.Release agent is chemically resistant, with difference
It is not dissolved when chemical analysis (the especially styrene and amine) contact of resin.Release agent also has heat-resisting and stress performance,
It is not easily decomposed or wears；Release agent is adhered on mold and is not transfer on processed product, do not interfere spray painting or other two
Secondary process operation.Due to the rapid development of the techniques such as injection molding, extrusion, calendering, molding, lamination, the dosage of release agent is also significantly
It improves on ground.
In Al alloys andMg alloys press casting procedure, it is necessary to using release agent come jet mould smoothly to be obtained at the end of each circulation
Obtain cast product.Release agent can manually or automatically spray, and in both cases, a large amount of release agent is directed on mold, small
Part is evaporated in an atmosphere, but then most of extra release agent falls under gravity into flow through molds on floor.
In Die Casting Industry, in order to demould die casting well, it is necessary to using release agent come jet mould, to follow every time
Cast product is smoothly obtained at the end of ring, and also can increase the surface smoothness of die casting, protective film tool, and extend mold
Service life.However, in actual production, release agent only has 30%-65% release agent during the sprinkling of high-pressure high-flow
Service efficiency, remaining is mostly directly discharged to cesspool in a manner of sewage.Since release agent is by a variety of industrial chemicals
Chemical liquids made of emulsification, it is not only monovalent at high cost, but also there is the harmful organic principle in a variety of pairs of bad borders.Direct emission demoulding
Agent waste water can not only bring huge injury to periphery bad border, and for enterprise and very big cost wastes, the section advocated with country
Energy environmental protection policy runs in the opposite direction.
On the other hand, release agent is in course of injection, since the high temperature of die surface influences, high pressure gas, die surface
The aluminium of attachment cuts, machine oil and other substances etc. mix together during high-pressure injection, so that original room temperature is de-
The very big physicochemical change that mould dilution agent solution occurs, so that the recycling and reusing difficulty to release agent waste water substantially mentions
It is high.Currently, since impurity does not clean up, recycling quality and using effect by general release agent recycling and reusing method
Generally, the poor service life that can even reduce die casting quality and die casting of effect.
