Abstract
The invention relates to a Laval spray pipe for preparing a die casting die releasing agent. The Laval spray pipe for preparing the die casting die releasing agent is set in segments, and comprises a front cross section reduction segment, a rear cross section reduction segment, and a liquid and material mixing segment which is arranged between the front cross section reduction segment and the rear cross section reduction segment and used to proportion materials, wherein water inlets are formed in the fronts of the cross section reduction segments, and a medicament inlet is formed in the side face of the liquid and material mixing segment. The Laval spray pipe for preparing the die casting die releasing agent is low in failure rate and stable in proportioning, and can achieve automatic preparation.
Description
Technical field
The present invention 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 the heat conduction of mould, reduce aluminium alloy to the souring of mould, protection improve the condition of work of mould, generally all use releasing agent.Its releasing agent stoste mixes 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 increase simultaneously, easily cause environmental pollution and increase disposal cost.On the other hand, as concentration is too rare, do not have the effect of the demoulding, this just proposes higher requirement to the proportioning of releasing agent.
At present, be all use Israel TEFFN(safe fragrant at Die Casting Industry most enterprises), French DOSATRN hydraulic automatism proportioning machine, its with the pressure of water for power, drive dosing piston, back and forth movement, extracts releasing agent stoste and after fully mixing with water, force feed is to preparing bucket.Be characterized in installing and with easy to maintenance, being directly installed on feed pipe, without the need to electric power, and the power using hydraulic pressure as work, easy to use, as long as open water source.Add proportion adjustment flexible, ratio adds mixing accurately, not by flow, the pressure fluctuations of water, how the flow and the pressure that no matter flow through pipeline change, the demoulding dosage injected is directly proportional to the water yield flowing through water pipe, outside adjustment ratio knob, can reach the object regulating concentration, flexibly and easily.
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 large, affect compound concentration.Accessory difficulty is purchased simultaneously, price is too high, maintenance difficult.
Summary of the invention
The present invention is directed to above-mentioned defect, it is extremely low that object is to provide a kind of fault rate of equipment, and proportioning is very stable, and can realize the Rafael nozzle for casting mold-releasing agent preparation of automatic preparation.
The technical solution used in the present invention is for this reason: subsection setup of the present invention, comprises anterior reduced cross-sectional section, the cross section expanding reach at rear portion, and is arranged on the liquid material mixing section playing 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.
Be detachable connection between described each section, be threaded connection between each section.
Described medicament inlet place is provided with the control valve of regulating agent flow.
Sealing device is established in each section of junction.
Advantage of the present invention is: 1) the present invention utilizes the suction principle of Rafael nozzle, movement-less part, and the fault rate of equipment is extremely low, proportioning is very stable, when water flow pressure changes in flow rate, the change that the pressure at trunnion place, flow are proportional, its proportioning is substantially constant; 2) adopt Demountable form between each section of the present invention, 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 when damaging, only this section need be changed; Avoid monoblock type Rafael nozzle one place and damage the defect just will scrapped; 3) the present invention 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 present invention make use of the characteristic of Rafael nozzle cleverly, serves the result of use to releasing agent automatic preparation, has and prepares advantage that is stable, long service life.

Detailed description of the invention
Subsection setup of the present invention, 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 playing 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 portion, and liquid material mixing section 2 side is provided with medicament inlet.
Be detachable connection between described each section, be threaded connection between each section.
Described medicament inlet place is provided with the control valve of regulating agent flow, by control valve regulating agent flow.
The present invention establishes 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 mark, and liquid level mark place is provided with electric installation, and Rafael nozzle is provided with the magnetic valve be connected with electric installation.
As long as the present invention installs, cross section expanding reach 1, liquid material mixing section 2, reduced cross-sectional section 3 connect sequentially through thread by debugging.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 and releasing agent are prepared bucket and be connected.According to technology Calculation, its tap water pressure>=2.5kg/cm
2; In addition in order to easy to adjust, liquid material mixing section 2 increases a needle type regulating valve, 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.
