Metal injection molded technology has in preparation and has unique advantage aspect complicated shape, uniform formation's structure and the high performance high accuracy injection-molded product.The all any metal or alloy that can make powder are available the method finished parts all.In addition, this technology can realize fully that automation works continuously, and production efficiency is high, and stock utilization almost can reach 100%.
Metal dust must add a certain amount of binding agent (large section be paraffin) before injection moulding, then mixing one-tenth metal feeding at a certain temperature.Binding agent is quite crucial in metal injection molded middle role, only after adding a certain amount of binding agent, metal-powder just can have suitable flowability, can be suitable for injection moulding, binding agent plays a part again to keep article shape after being shaped, until till being removed by degreasing before the sintering.It is 40-60% that the content of binding agent is generally volume fraction.
Metal injection molding blank must carry out solvent degreasing before vacuum-sintering, discharge section paraffin, get through blank surface capillary channel, the discharge of a large amount of nonmetallic substances and sintering densification when being convenient to vacuum-sintering, the uniformity that this process is put cleannes and the object of solvent is strict, rising or falling speed to solvent temperature is relatively more responsive, and is perfect to the coherence request of each degreasing effect, controls bad product quality and the waste solvent material of having a strong impact on.But the general tank of existing solvent degreasing device normal operation is difficult to satisfy instructions for use.
Summary of the invention
Technical problem to be solved by this invention just provides a kind of metal injection molding blank solvent degreasing plant, and is simple in structure, guarantees the cleannes of solvent and the uniformity that object is put, and simultaneously solution temperature fluctuation is little, guarantees the uniformity of each degreasing effect.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: a kind of metal injection molding blank solvent degreasing plant, it is characterized in that: the described cell body of the cell body top that comprises sealing is provided with several openings in turn, opening is sealed by seal cover, described cell body top is provided with electric block, is provided with heater in the described cell body.
As preferably, described cell body wall is provided with interlayer, and described heater is the heating rod of being located in the described interlayer.Heating effect is good, and is little on the cleannes impact of solution.
As preferably, be provided with temperature sensor in the described cell body, described heating rod connects controller, and temperature sensor feeds back to controller with temperature signal, the work of controller control heating rod.Realize the good control of solution temperature, the solution temperature fluctuation is little.
As preferably, described cell body outer wall is provided with heat-insulation layer.High insulating effect.
As preferably, described cell body evenly is divided at least two sections, and every section correspondence arranges heating rod, temperature sensor and controller, realizes that solution temperature is independently controlled in every section cell body.The solution temperature fluctuation is little, guarantees each both uniformity of each workpiece degreasing effect.
As preferably, be equipped with even distributor in described every section cell body.Even distributor can be stirring vane, guarantees the uniformity of solution.
As preferably, be provided with dividing plate between described each section cell body, the dividing plate upper edge is lower than liquid level, and the dividing plate lower edge is higher than the cell body bottom surface.Both realized that solution temperature was independently controlled in every section cell body, and solution intercommunication in each section cell body, the uniformity of assurance solution.
As preferably, be provided with shower in the described cell body.Both can inject solution by shower, also can make things convenient for the cleaning of cell body.
As preferably, be provided with below the described cell body and pick out pipeline communication mixed liquor separator, the described pipeline that picks out is provided with the valve whether the control pipeline is communicated with.
The present invention is in injection moulding blank solvent degreasing process, blank is put into fixing pallet, hang in stainless steel rectangle cell body by hanging basket with electric block, then cover seal cover, technological temperature and degreasing time that automatic setting needs after degreasing is finished hang out product and can be sent to the workshop sintering, easy and simple to handle like this, degreasing uniformity and excellent in stability, equipment totally closed operation environmentally safe is carried out in the perfection of assurance follow-up sintering operation.
Description of drawings
The invention will be further described below in conjunction with the drawings and specific embodiments:
Fig. 1 is structural representation of the present invention;
Fig. 2 is top view of the present invention;
Fig. 3 is side view of the present invention.
The specific embodiment
As shown in Figure 1 to Figure 3, be the embodiment of a kind of metal injection molding blank solvent degreasing plant of the present invention, comprise that the cell body 3 described cell body tops of sealing are provided with several openings in turn, opening is by seal cover 2 sealings, described cell body top is provided with electric block 1, is provided with heater in the described cell body.Described cell body wall is provided with interlayer 6, and described heater is the heating rod 7 of being located in the described interlayer.Be provided with temperature sensor in the described cell body, described heating rod connects controller, and temperature sensor feeds back to controller with temperature signal, the work of controller control heating rod.Described cell body outer wall is provided with heat-insulation layer 5.Described cell body evenly is divided at least two sections, and every section correspondence arranges heating rod, temperature sensor and controller, realizes that solution temperature is independently controlled in every section cell body.Be equipped with even distributor 8 in described every section cell body.Be provided with dividing plate 9 between described each section cell body, the dividing plate upper edge is lower than liquid level, and the dividing plate lower edge is higher than the cell body bottom surface.Be provided with shower in the described cell body.Described cell body below is provided with and picks out pipeline 4 connection mixed liquor separators, and the described pipeline that picks out is provided with the valve whether the control pipeline is communicated with.
Producing principle of the present invention is: doing one has the totally-enclosed stainless steel cuboid of interlayer cell body, and the small-sized electric cucurbit is installed above cell body, and cell body is installed heat-insulation layer outward, to reduce heat loss in the heating process, keep temperature constant, in cell body stainless steel interlayer, electrically heated rod is installed, temperature automatically controlled.The cell body below picks out the straight-through mixed liquor separator of pipeline, in order to can directly advance the separator separation through the mixed liquor of degreasing, cuts down the number of intermediate links, and prevents the mixed liquor contaminated environment.
Cell body is divided into four sections, every section independent temperature control, temperature control is accurate like this, opens three with the round mouth of sealing lid for every section, and object is placed in the special hanging basket and puts into the stainless steel round mouth by electric block, then cover seal cover, be isolated from the outside like this, reduce and pollute, cell body is divided into four sections differences that can arrange according to the difference of degreasing effect and requirement like this solvent strength in independent four sections, can reach so the different degreasing requirement of different blanks, reach perfect sintering effect.
Through the not reusable mixed liquor of degreasing, deliver to the mixed liquor separator by special device and pipeline and carry out lock out operation, twice laid, protection of the environment reduces cost.
