The utility model content
The utility model provides a kind of vacuum aided Coinjection molding apparatus for solving the problems of the technologies described above, and this installation cost is low, not fragile, simple to operate, efficient is high, convenience for washing.
For achieving the above object, the technical scheme that the utility model adopts is following:
A kind of vacuum aided Coinjection molding apparatus; It is characterized in that; Comprise the loam cake at main body, main body top and the base of bottom and main body seamless link; Can arbitrarily open and lock sealing between said loam cake and the main body, cover on said and offer the vacuum orifice and the pressure modulating opening that is used for setting pressure regulating system joint that is used to install the vacuum orifice joint, offer the resin injection mouth on the said base.
Said loam cake and main body connecting portion adhering and sealing packing ring.
Between said loam cake and the main body retaining mechanism is installed, said retaining mechanism is arranged on the equally distributed C type folder of body peripheral edge.
Said main body, base, loam cake and C type folder material are steel or stainless steel.
Said pressure regulating system comprises air inlet connections, is connected with Pressure gauge, pressure regulator valve and relief valve on the said air inlet connections.
Cover on said and also offer the handle aperture that is used to install portable handle joint.
Respectively weld an external diameter and mouthful identical, the threaded hollow pole of inner wall belt of diameter in said vacuum port, pressure modulating opening, handle aperture and the resin injection mouth; All be tied with the degreasing band on said vacuum orifice joint, pressure regulating system joint and the portable handle joint, in being threaded in separately mouthful.
Said resin is epoxy resin, unsaturated-resin, vinylite or acrylic resin.
The beneficial effect of the utility model is following:
The device of the utility model adopts air pressure that resin is directly injected die cavity, install simple to operate, efficient is high;
The device of the utility model itself is lower, economic and practical with the parts cost;
The device of the utility model can arbitrarily be adjusted injection pressure (0-0.7Mpa) and injection speed with the type of the resin of selecting for use according to the size of injection product.Relief valve can discharge the pressure in the main body, and the device for opening loam cake is observed state of resin in the main body, according to the size of injection product, in injection process, can also in apparatus main body, add resin.Operate very flexible, easy to use, quick.Can the bubble in the inner resin of container be taken out injection back product surface better effects and if have vacuum orifice.
Description of drawings
Fig. 1 is the structural representation of the utility model.Among the figure: 1, vacuum-pumping tube, 2, C type folder, 3, portable handle, 4, air inlet pagoda joint, 5, relief valve, 6, pressure regulator valve, 7, Pressure gauge, 8, the resin injection mouth, 9, main body, 10, loam cake, 11, base.
The specific embodiment
Below in conjunction with specific embodiment the utility model is elaborated.Following examples will help those skilled in the art further to understand the present invention, but not limit the utility model in any form.Should be pointed out that to those skilled in the art, under the prerequisite that does not break away from the present invention's design, can also make some distortion and improvement.These all belong to the protection domain of the utility model.
Vacuum aided Coinjection molding apparatus shown in Figure 1, that the utility model provided comprises the base 11 of main body 9, main body 9 bottoms and the loam cake 10 at top, all is to adopt the steel or stainless steel of 2mm to be stamped to form, and its diameter is 400mm.Base 11 welds together with main body 9, requires no seam welding, firm welding.
In the position apart from main body 9 upper end 50mm, main body 9 periphery four the C types folders 2 that evenly distribute are used for locking loam cake 10 and main body 9, also can be random unclamp so that main body 9 takes up resin.It is steel or stainless steel that this C type presss from both sides 2 materials.
Bore the resin injection mouth 8 that diameter is 22mm in the center of base 11, and then be 22mm at external diameter of 8 li welding of resin injection mouth, inside is M19, and length is the hollow pole of 80mmm, and resin is promptly injected out from the port of this hollow pole.
On loam cake 10, bore the hole of three 18mm, be respectively vacuum orifice, handle aperture and pressure modulating opening.In each mouthful, respectively welding an external diameter is 18mm, and inside is M12, and length is the hollow pole of 50mm, then vacuum orifice pagoda joint, portable handle 3, pressure regulating system joint is installed in respectively in the good screw thread mouth of these three welding.Should on each nipple, twine 4-5 circle degreasing band before installing earlier, guarantee to install firm, tight.Vacuum orifice can connect vavuum pump through vacuum-pumping tube 1 extracts the bubble in the resin in the main body 9 out, and the quality of injection back product surface is better.
Pressure regulating system comprises air inlet pagoda joint 4, the relief valve 5 that is connected with Pressure gauge 7, pressure regulator valve 6 respectively and is used to discharge main body 9 internal gas pressures with air inlet pagoda joint 4.Pressure regulator valve 6 is arbitrarily adjusted injection pressure (0-0.7Mpa) and injection speed according to the size of injection product with the type of the resin of selecting for use.Relief valve 5 can discharge the pressure in the main body 9, observes state of resin in the main body thereby open loam cake 10, according to the size of injection product, in injection process, can also in main body 9, add resin.
With diameter is that the rubber gasket of 400mm is bonded on the loam cake 10, then loam cake 10 is covered on main body 9, and with loam cake 10 and main body 9 lockings, the seal washer good seal can use with four C types folders 2.
In sum, the device of the utility model adopts air pressure that resin is directly injected die cavity, install simple to operate, efficient is high; The device of the utility model itself is lower, economic and practical with the parts cost.
