Description
Technical field
The present invention relates to injection mo(u)lding automatic industrial equipment technical field, specifically a kind of large discharge vacuum generating device utilizing malleation source of the gas to produce negative pressure source of the gas.
Background technology
In the taking-up automatic field of existing injection moulding plastic mould goods, vacuum generator produces vacuum by compressed air, this vacuum generating device many with sucker with the use of, carry out the absorption of various material, carrying, there is volume little, lightweight, the advantages such as noise is little.Especially in injection mo(u)lding automated production industry, goods are taken out by the vacuum cup absorbent articles on the jig plate utilizing mechanical arm front end to fix from forming machine, use particularly extensive.But very little for surface area, the even sucker product that all cannot adsorb, use and thisly produce negative pressure of vacuum by vacuum generator in sucker suction chamber and carry out adsorption production, just seeming to compare difficult for.
Summary of the invention
The deficiency of being inconvenient to take out microminiature product is coordinated with sucker for overcoming existing vacuum generating device, goal of the invention of the present invention is to provide a kind of large discharge vacuum generator, adsorbable trickle product, and vacuum can be become at any time into blowing, stick to because of reasons such as electrostatic the problem that fixture cannot be taken off to solve thin microminiaturized product.
For achieving the above object, the two ends that side stand is spread in the present invention are connected with inlet side support, muffler respectively; With diffusion chamber in diffusion side stand, with adsorbent chamber in inlet side support, one end of diffusion chamber communicates with adsorbent chamber, the other end joint noise reduction device of diffusion chamber; Diffusion side stand is equipped with gas-tpe fitting one, and inlet side support is equipped with gas-tpe fitting two, gas-tpe fitting one communicates with diffusion chamber, and gas-tpe fitting two communicates with adsorbent chamber; The gap formed between described diffusion side stand and inlet side support, is the nozzle that can produce high-speed jet; Sealing ring is provided with between described diffusion side stand and inlet side support; Diffusion side stand and inlet side support adopt superduralumin material to make, and carry out anodized.
When adsorbing plastic, compressed air imports diffusion chamber from air inlet side by gas-tpe fitting one, and the fit clearance place between diffusion side stand and inlet side support forms high-speed jet, in this process, due to the viscosity of gas, high-speed jet can entrainment the gas near jet exit, make Pressure Drop in adsorbent chamber to atmospheric pressure, certain vacuum is formed at inlet side, the air in short space jig plate accommodating microminiature plastic is taken away in high-speed jet, and small plastic is adsorbed in the short space holding plastic simultaneously.Due to muffler, significantly reduce the noise that exhaust side high velocity air produces.When not needing vacuum, when product is come off, gas can be imported from the gas-tpe fitting two of adsorbent chamber, blowing to inlet side, cancel out each other with the vacuum pneumatic formed, thus reach the object destroying vacuum.Diffuser casing and vacuum generation chamber adopt superduralumin material to make, and carry out anodized.
The present invention is different from the scheme that like product adopts aperture to accelerate, and utilizes diffusion side stand and the matched in clearance between inlet side stent cover and face, forms nozzle, increase air-flow acceleration region area, improve source of the gas utilization rate, make the air velocity of acceleration faster, flow is larger.
The present invention compared with prior art, has the following advantages:
1, vacuum space is little, and response is fast, and lightweight, noise is little, and is tubular design, can be connected with jig plate neatly.
2, vacuum is little, and flow is large, and more accurately fast, the manipulator for microminiature product takes out ideal effect to extraction efficiency automatically.Be widely used in injection mo(u)lding automatic industrial the taking-up being difficult to the microminiature product taken out.
3, with vacuum breaking function, vacuum can being become at any time into blowing, after product takes out by fixture, when needing product to discharge, just can rapidly product be blown out.

Detailed description of the invention
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5, diffusion side stand 2 adopts superduralumin material to make with inlet side support 3, and carries out anodized; The two ends of diffusion side stand 2 are connected with inlet side support 3, muffler 5 respectively; With diffusion chamber 6 in diffusion side stand 2, with adsorbent chamber 7 in inlet side support 3, one end of diffusion chamber 6 communicates with adsorbent chamber 7, the other end joint noise reduction device 5 of diffusion chamber 6; Diffusion side stand 2 is equipped with gas-tpe fitting 1, and inlet side support 3 is equipped with gas-tpe fitting 24, gas-tpe fitting 1 communicates with diffusion chamber 6, and gas-tpe fitting 24 communicates with adsorbent chamber 7; The gap formed between diffusion side stand 2 and inlet side support 3, is the nozzle 9 that can produce high-speed jet; Sealing ring 8 is provided with between diffusion side stand 2 and inlet side support 3.
When adsorbing plastic, as Fig. 2, shown in Fig. 3, compressed air imports diffusion chamber from air inlet side by gas-tpe fitting 1, and fit clearance (nozzle 9) place between diffusion side stand 2 and inlet side support 3 forms high-speed jet, Compressed Gas is looped around around nozzle ring 9 negative pressure cavity gas, complete air-flow to accelerate, in this process, due to the viscosity of gas, high-speed jet can entrainment the gas near jet exit, make Pressure Drop in adsorbent chamber 7 to atmospheric pressure, due to malleation source of the gas supply endlessly, adsorbent chamber 7 just defines stable negative pressure source of the gas, namely certain vacuum is formed at inlet side, the air in short space jig plate accommodating microminiature plastic is taken away in high-speed jet, small plastic is adsorbed in the short space holding plastic simultaneously.The high-speed jet that this structure overcomes existing vacuum generator only entrainments the gas of adsorbent chamber from unilateral direction, but by the gas being included in high-speed jet interior zone in a large number and take away rapidly, powerful vacuum can be set up rapidly at any time in the small adsorbent chamber that jig plate holds plastic, rapid adsorption lives plastic, substantially increases the extraction efficiency of die products.Due to muffler 5, accelerate air-flow and be diffused in air by muffler 5, while ensureing the smooth and easy discharge of gas, significantly reduce again the noise that exhaust side high velocity air produces.
As shown in Fig. 5 (the C-C sectional view of Fig. 4), after product takes out by fixture, product is needed to discharge, when product is come off, airflow direction as shown in Figure 5, can import gas from the gas-tpe fitting 24 of adsorbent chamber 7, blow to inlet side, cancel out each other with the vacuum pneumatic formed, thus reach the object destroying vacuum.
