Abstract
The utility model relates to a Laval nozzle for the preparation of die casting release agent. The Laval nozzle comprises a front reduced-section segment, a rear enlarged-section segment, and a liquid mixing segment, wherein the liquid mixing segment disposed between the reduced-section segment and the enlarged-section segment is used for matching materials, the front of the reduced-section segment is provided with a water inlet, and the side of the liquid mixing segment is provided with a drug inlet. The Laval nozzle for the preparation of die casting release agent and a release agent automatic preparation device are very low in failure rate, allows matching ratio to be highly stably, and allow for automatic preparation.
Description
Technical field
The utility model relates to a kind of Rafael nozzle for casting mold-releasing agent preparation.
Background technology
In Die Casting process, in order to prevent the adhesion of product and mould, reduce mould heat conduction, reduce aluminium alloy to the souring of mould, protection and improve the condition of work of mould, generally all use releasing agent.Its releasing agent stoste is mixed by a certain percentage with water, and as concentration is too high, although stripping result is good, product has decorative pattern, affects the outward appearance of product, consumes and increases simultaneously, easily causes environmental pollution and increases disposal cost.On the other hand, as too rare in concentration, do not have the effect of the demoulding, this has just proposed higher requirement to the proportioning of releasing agent.
At present, at Die Casting Industry most enterprises, be all to use the Israel TEFFN(safe fragrant), French DOSATRN hydraulic automatism proportioning machine, its pressure of take water is power, drive dosing piston, back and forth movement, after extracting releasing agent stoste and fully mixing with water, force feed is to preparation bucket.Be characterized in installing and with easy to maintenance, being directly installed on feed pipe, without electric power, and using hydraulic pressure as the power of working, easy to use, as long as open water source.Add ratio flexible adjustment, ratio adds mixing accurately, not affected by flow, the pressure oscillation of water, how the flow and the pressure that no matter flow through pipeline change, the demoulding dosage injecting is directly proportional to the water yield that flows through water pipe, outside adjusting ratio knob, can reach the object that regulates concentration, flexible.
But, everything divides into two, although hydraulic automatism proportioning facility have above-mentioned many advantages, because it utilizes hydraulic drives piston back-and-forth movement, extract releasing agent stoste, its moving component is many, and the fault rate of equipment is high, on the other hand, reciprocating motion of the pistons, wearing and tearing are large, leak greatly, affect compound concentration.Accessory difficulty is purchased simultaneously, price is too high, maintenance difficult.
Utility model content
The utility model is for above-mentioned defect, and object is to provide a kind of fault rate of equipment extremely low, and proportioning is very stable, and can realize the Rafael nozzle for casting mold-releasing agent preparation of automatic preparation.
The technical solution adopted in the utility model is for this reason: the utility model subsection setup, comprises anterior reduced cross-sectional section, the cross section expanding reach at rear portion, and be arranged on the liquid material mixing section that plays material proportion between reduced cross-sectional section, cross section expanding reach; Water inlet is established in described reduced cross-sectional section front portion, and liquid material mixing section side is provided with medicament inlet.
Between described each section, be detachable connection, between each section, be threaded connection.
Described medicament inlet place is provided with the control valve of regulating agent flow.
Sealing device is established in each section of junction.
The utility model has the advantages that: 1) the utility model utilizes the suction principle of Rafael nozzle, movement-less part, the fault rate of equipment is extremely low, proportioning is very stable, when water flow pressure changes in flow rate, in the proportional variation of pressure, flow at trunnion place, its proportioning is substantially constant; 2) between each section of the utility model, adopt Demountable form, greatly reduce the manufacture difficulty of Rafael nozzle, and adopt thread connecting mode, assembling is quick; And Demountable can reduce use cost, if wherein one section while damaging, only need be by this section replacing; The defect of having avoided the one place damage of monoblock type Rafael nozzle just will scrap; 3) the utility model arranges control valve at medicament inlet place, by regulating needle type regulating valve, can change the ratio of its proportioning, very easy to use.
In sum, the utility model has utilized the characteristic of Rafael nozzle cleverly, has played the result of use to releasing agent automatic preparation, has advantages of that preparation is stable, long service life.

Fig. 3 is the structural representation of liquid material mixing section.
Fig. 4 is the structural representation of cross section expanding reach.
In figure, 1 is that cross section expanding reach, 2 is that liquid material mixing section, 3 is reduced cross-sectional section.
The specific embodiment
The utility model subsection setup, comprises anterior reduced cross-sectional section 3, the cross section expanding reach 1 at rear portion, and is arranged on the liquid material mixing section 2 that plays material proportion between reduced cross-sectional section 3, cross section expanding reach 1; Water inlet is established in described reduced cross-sectional section 3 front portions, and liquid material mixing section 2 sides are provided with medicament inlet.
Between described each section, be detachable connection, between each section, be threaded connection.
Described medicament inlet place is provided with the control valve of regulating agent flow, by control valve regulating agent flow.
The utility model is established sealing device each section of junction.
Further, on the basis of the above, be also provided with the preparation bucket corresponding with Rafael nozzle, preparation bucket is provided with liquid level sign, and liquid level sign place is provided with electric installation, and Rafael nozzle is provided with the magnetic valve being connected with electric installation.
The utility model is installed, debugging needs only cross section expanding reach 1, liquid material mixing section 2, reduced cross-sectional section 3 are connected by thread in order.Thread junction can add fluid sealant or raw material band sealing.Cross section expanding reach 1 is connected with running water water source, and reduced cross-sectional section 3 is connected with releasing agent preparation bucket.According to technology Calculation, its tap water pressure>=2.5kg/cm
2; For easy to adjust, on liquid material mixing section 2, increase a needle type regulating valve in addition, its flow adjustment range 0～0.15 m
3/ h, by regulating needle type regulating valve, can change the ratio of its proportioning, very easy to use.
