Description
Technical field
The invention belongs to the degreasing equipment technical field that degreasing is used to powder metallurgy injection moulding blank, be specifically related to a kind of degreasing mechanism
Background technology
metal powder injection molding technology (Metal Injection Molding; Be called for short MIM) be multidisciplinary interpenetrating and the technology of intersecting such as collection plastics molding process, polymer chemistry, powder metallurgy technology and Metal Material Science, utilize mould can disposable injection moulding to go out the product of complicated shape and be able to make the structural member of high density, high accuracy and 3 D complex shape through sintering.This technology takes the lead in being invented in year in last century (1973) by California, USA Parmatech company, and early eighties is used widely America and Europe and Japan etc.This technology have processing step few, need not to cut or cutting and the high strong point of economic benefit on a small quantity, and can overcome that traditional powder metallurgical technique extrudate density is low, material is inhomogeneous, mechanical and physical performance is poor, the shortcoming of the slim and baroque part of easy-formation not.
metal powder injection molding is realized through adding binding agent; Promptly give the sufficient flowability of metal dust and use the blank that acquisition has the specific products characteristic by binding agent; Blank removes through the binding agent that follow-up degreasing process will before add, and obtains having the product of metal or ceramic performance again through high temperature sintering.Specifically can be summarized by following flow process: metal dust mixes (abbreviation batch mixing), granulation, the post processing through mold injects moulding, degreasing (industry is also claimed unsticking), sintering and necessity with binding agent.
The system that
are used for the known binding agent of metal powder injection molding mainly contains paraffinic base system and aldehyde resin system.The removal methods of binding agent mainly contains four kinds: the one, and the solvent degreasing method; The 2nd, hot degreasing method; The 3rd, siphon degreasing method; The 4th, the catalysis degreasing method of adhesive special system.In above-mentioned four kinds of methods, the solvent method degreasing has the terse relatively strong point of equipment, thereby is generally used by industry.
Chinese invention patent publication number CN101653665A has recommended " liquid solvent extracting and degreasing device that is used for metal powder injection molded blank "; Be connected through pipeline between the inlet of this device with the outlet of blank accommodating container and auxiliary circulation container; And an aspirator is connected in series between the inlet of blank accommodating container and auxiliary circulation outlet of container; Make the extract circulation and use intensified response efficient, promptly improve degreasing effect to improve effect of extracting.
again; CN202113637U has disclosed " powder injection forming blank solvent degreasing device "; This patent by solvent degreasing groove, the condensing and recycling device that is connected with the solvent degreasing groove and be connected the solvent degreasing groove and the condensing and recycling device between distilling apparatus constitute, have the 0016th section described technique effect of specification.
In
above-mentioned two patent schemes the former is owing to only depend on aspirator to make the extract circulating reflux; The measure that shortage heats up to extract; Therefore extraction efficiency is that degreasing efficient and effect can only lean on the tediously long time to obtain; Both be unfavorable for enhancing productivity, also be not easy to energy savings.And the latter is opposite to that extract in the blank in the solvent degreasing groove and binding agent Gas Recovery condensation volatilization under degreasing heater and/or the heating of water-bath heater through the condensing and recycling device; Thereby the collecting effect of binding agent gas can't show gratifying degree, because the binding agent gas of volatilization only just is able to get into the condensing and recycling device through a unique pipeline or the title passage that is used to connect between solvent degreasing groove and the condensing and recycling device.And, because limit degreasing and collection Volatile Gas carry out reducing to a certain extent the temperature of solvent degreasing synchronously, prolong degreasing time, increase the energy resource consumption of degreasing heater.
In view of above-mentioned prior art, be necessary to improve, the applicant has done useful design for this reason, and the technical scheme that will introduce below is under this background
Summary of the invention
task of the present invention is to provide a kind of quality that helps to significantly improve degreasing speed and degreasing effect and use energy savings and guarantee blank to help introducing and discharge the degreasing mechanism of the extractant that degreasing uses.
task of the present invention is accomplished like this; A kind of degreasing mechanism; Comprise a casing that is arranged on the pedestal; Constitute a heating folder chamber in the bottom in the casing chamber of this casing, in this heating folder chamber, be provided with heater, and on the inwall at the nearly middle part of the short transverse in casing chamber, around inwall, constitute the remittance liquid bath that a ring leads to; Offer in the bottom of this remittance liquid bath one with the extraneous fluid hole that communicates; Be provided with in the bottom of a side of casing one be used for introducing extractant from the extractant that degreasing is used to blank to said casing chamber introduce interface, this extractant is introduced interface and is connected with the extractant storage tank through pipeline, and also be provided with in the bottom of a side of casing one communicate with the casing chamber be used for the outside discharge opeing interface that discharges of the endoceliac extractant of case; One refrigeration unit, this refrigeration unit are arranged on a side of said casing; One condenser coil, this condenser coil inwall around the said casing chamber lays, and corresponding to the top of said remittance liquid bath, wherein, the condenser coil inlet of condenser coil is connected with said refrigeration unit with the condenser coil liquid outlet.
in a concrete embodiment of the present invention, described heater is electric heater unit, steam heater or hot oil heater.
are equipped with the case lid that is used for the sealing of said casing chamber at the uncovered position on the top of described casing in another concrete embodiment of the present invention.
technical scheme provided by the invention has following technique effect with respect to prior art; One of which; Heater by being arranged in the heating folder chamber heats the endoceliac extract of case; Make the binding agent that is positioned in the endoceliac blank of case deviate from blank, thereby it is good to have heats, the fireballing strong point of degreasing; They are two years old; After extraction finishes; Under the condensation of condenser coil; Make in base substrate, shoot and disperse be that the glue cyclostrophic becomes liquid state and drops down and converge liquid bath in the endoceliac binding agent gas of case, draw by fluid hole, therefore will heat carry out stage by stage with condensation and help ensureing the casing chamber when heated condition temperature and use heat time heating time, raising solvent extraction speed and the energy savings that shortens heater; Its three, introduce the convenience that interface and discharge opeing interface are guaranteed feeding and discharge opeing by extractant, to alleviate operator's operation intensity.
