Description
Technical field
The utility model relates to injection mo(u)lding automatic industrial equipment technical field, specifically a kind of large flow vacuum generating device that utilizes 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, and the many and sucker of this vacuum generating device is used in conjunction with, carry out absorption, the carrying of various materials, there is volume little, lightweight, the advantage such as noise is little.Especially in injection mo(u)lding automated production industry, utilize the vacuum cup absorbent articles on the fixing jig plate of mechanical arm front end, goods are taken out from forming machine, use particularly extensive.But the product very little for surface area, even sucker all cannot adsorb, uses thisly by vacuum generator, to produce negative pressure of vacuum carry out adsorption production in sucker adsorbent chamber, just seems more difficult.
Summary of the invention
For overcoming existing vacuum generating device, coordinate the deficiency of being inconvenient to take out microminiature product with sucker, goal of the invention of the present utility model is to provide a kind of large flow vacuum generator, adsorbable trickle product, and can become at any time vacuum into blowing, to solve thin microminiaturized product because static etc. are former thereby stick to the problem that cannot take off on fixture.
For achieving the above object, the two ends of the utility model diffusion side stand are connected with inlet side support, muffler respectively; In diffusion side stand, with diffusion chamber, in inlet side support, with adsorbent chamber, one end of diffusion chamber communicates with adsorbent chamber, the other end joint noise reduction device of diffusion chamber; On diffusion side stand, gas-tpe fitting one is housed, gas-tpe fitting two is housed on inlet side support, gas-tpe fitting one communicates with diffusion chamber, and gas-tpe fitting two communicates with adsorbent chamber; The gap forming between described diffusion side stand and inlet side support, is the nozzle that can produce high-speed jet; Between described diffusion side stand and inlet side support, be provided with sealing ring; Diffusion side stand and inlet side support adopt superduralumin material to make, and carry out anodized.
When absorption 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, viscosity due to gas, high-speed jet meeting entrainments near gas jet exit, make Pressure Drop in adsorbent chamber to atmospheric pressure, at inlet side, form certain vacuum, the air in the short space that accommodates microminiature plastic on jig plate is taken away in high-speed jet, and small plastic is adsorbed in the short space that holds plastic simultaneously.Due to muffler, effectively reduced the noise that exhaust side high velocity air produces.When not needing vacuum, when product is come off, can import gas from the gas-tpe fitting two of adsorbent chamber, to inlet side, blow, cancel out each other with the vacuum pneumatic forming, thereby reach the object of destroying vacuum.Diffuser casing and vacuum generation chamber adopt superduralumin material to make, and carry out anodized.
The utility model is different from the scheme that like product adopts aperture to accelerate, and utilizes the matched in clearance between diffusion side stand and inlet side stent cover and face, forms nozzle, increased air-flow acceleration region area, improved source of the gas utilization rate, made the air velocity of acceleration faster, flow is larger.
The utility model 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, takes out efficiency more accurately fast, for the manipulator of microminiature product, automatically takes out and has ideal effect.Be widely used in the taking-up that is difficult to the microminiature product of taking-up in injection mo(u)lding automatic industrial.
3, with vacuum breaking function, can become at any time vacuum into blowing, after fixture takes out product, when product need to be discharged, just can rapidly product be blown out.

The specific embodiment
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5, diffusion side stand 2 adopts superduralumin materials 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; In diffusion side stand 2, with diffusion chamber 6, in inlet side support 3, with adsorbent chamber 7, one end of diffusion chamber 6 communicates with adsorbent chamber 7, the other end joint noise reduction device 5 of diffusion chamber 6; On diffusion side stand 2, gas-tpe fitting 1 is housed, gas-tpe fitting 24 is housed on inlet side support 3, gas-tpe fitting 1 communicates with diffusion chamber 6, and gas-tpe fitting 24 communicates with adsorbent chamber 7; The gap forming between diffusion side stand 2 and inlet side support 3, is the nozzle 9 that can produce high-speed jet; Between diffusion side stand 2 and inlet side support 3, be provided with sealing ring 8.
When absorption plastic, as Fig. 2, shown in Fig. 3, compressed air imports diffusion chamber from air inlet side by gas-tpe fitting 1, and the fit clearance (nozzle 9) between diffusion side stand 2 and inlet side support 3 locates to form high-speed jet, Compressed Gas is looped around around nozzle ring 9 negative pressure cavity gases, completing air-flow accelerates, in this process, viscosity due to gas, high-speed jet meeting entrainments near gas jet exit, make Pressure Drop in adsorbent chamber 7 to atmospheric pressure, due to malleation source of the gas supply endlessly, adsorbent chamber 7 has just formed stable negative pressure source of the gas, at inlet side, form certain vacuum, the air in the short space that accommodates microminiature plastic on jig plate is taken away in high-speed jet, small plastic is adsorbed in the short space that holds plastic simultaneously.The high-speed jet that this structure has overcome existing vacuum generator only entrainments the gas of adsorbent chamber from one-sided direction, but the gas that is included in high-speed jet interior zone is taken away in a large number and rapidly, can be at any time within holding the small adsorbent chamber of plastic, jig plate sets up powerful vacuum rapidly, adsorb rapidly plastic, greatly improved the taking-up efficiency of die products.Due to muffler 5, accelerate air-flow and be diffused in atmosphere by muffler 5, when guaranteeing the smooth and easy discharge of gas, effectively reduced again the noise that exhaust side high velocity air produces.
As shown in Fig. 5 (the C-C cutaway view of Fig. 4), after fixture takes out product, product need to be discharged, 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, to inlet side, blows, cancel out each other with the vacuum pneumatic forming, thereby reach the object of destroying vacuum.
