Problems solved by technology
Due to the high viscosity of the paint, there is a dead angle in the mixing tank for mixing the paint, resulting in insufficient stirring of the paint in this area, which affects the use effect of the entire paint
[0006] During the dip coating operation, if the coating in the dip coating tank is not stirred for a long time, there will be a tendency to stratify, the refractory aggregate with a large specific gravity will sink, and the adhesive and other components will float up, resulting in unstable hanging coating quality
[0007]
In summary, there are obviously inconveniences and defects in the actual use of the existing technology, so it is necessary to improve

Embodiment 1
[0066] Example 1, see figure 1 , including a feeder 1, a mixer 2 and a dip coating mechanism 3 connected in sequence; the dip coating mechanism 3 includes a dip coating box 31, and a mobile stirring mechanism is arranged in the dip coating box 31.
[0067] This implementation is suitable for flexible production, without manual real-time mixing, reducing labor intensity and improving labor efficiency. The labor intensity of feeding is reduced, and the dust generated when feeding directly into the mixer 2 is also avoided.
Embodiment 2
[0068] Example 2, see figure 2 , including a feeder 1, a mixer 2 and a dip coating mechanism 3 connected in sequence;
[0069] This implementation is suitable for continuous multi-person production. During the dip coating operation, the paint in the box is stirred in real time, which saves the manual stirring step, improves efficiency, and ensures the stability of dip coating quality. The labor intensity of feeding is reduced, and the dust generated when feeding directly into the mixer 2 is also avoided.
Embodiment 3
[0070] Example 3, see image 3 , including a feeder 1, a mixer 2 and a dip coating mechanism 3 connected in sequence; A bottom agitator 5 may be provided in the dipping tank 31, or a mobile agitating mechanism may be provided. The labor intensity of feeding is reduced, and the dust generated when feeding directly into the mixer 2 is also avoided.
[0071] This implementation is suitable for continuous mass production. The paint in the box returns to the mixer 2 in real time and remixes with the freshly mixed paint and then returns to the dip coating box 31, which ensures the consistency of the paint concentration in the box and eliminates the need for different mixing batches. The difference in paint concentration caused by the second time improves the quality stability of the dip coating.
[0072] In summary, the present invention connects feeder, mixer and dip-coating mechanism successively; Dip-coating mechanism comprises dip-coating box; Adopt sealing connection between ...

Abstract
The invention relates to the technical field of paint dip-coating equipment for production of engine parts and provides a lost-foam paint concentration real-time adjusting apparatus for exterior support production, comprising a screw feeder, a mixer and a dip-coating mechanism which are connected in sequence; the dip-coating mechanism comprises a dip-coating box connected with the mixer through acirculating pump; the mixer includes a stirring barrel in which a main stirrer is arranged; the top of the stirring barrel is also provided with a circular transmission component which is in serial transmission connection with a plurality of auxiliary stirrers. The feeder and the mixer are hermetically connected; therefore, dust caused during feeding is avoided. The circular transmission componentis in serial transmission connection with the multiple auxiliary stirrers; therefore, stirring dead corners are avoided. The dip-coating box is connected with the mixer via the circulating pump; therefore, the lost-foam paint concentration real-time adjusting apparatus for exterior support production is suitable for continuous batch production. A paint in a box is returned into the mixer in realtime to remix with a newly mixed paint before the mixture is returned to the dip-coating box; therefore, differences of paint concentrations due to differences of mixing batches are eliminated, and quality stability is improved for the dip-coating paint.
Description
technical field [0001] The invention relates to the technical field of a paint dipping device for the production of engine parts, in particular to a real-time adjustment device for the concentration of the lost foam paint used for the production of an outer support. Background technique [0002] At present, the manufacturing method of engine parts is basically to cast blanks first and then perform machining. Most parts suppliers process a wide variety of types and varieties, and many products have complex shapes and structures. Therefore, many manufacturers choose to produce more flexible lost foam casting in blank casting. [0003] Lost foam casting, also known as investment casting, is to bond and combine foam models similar in size and shape to castings to form a model cluster. After brushing refractory paint and drying, it is buried in dry quartz sand for vibration molding, and poured under negative pressure. A new casting method in which the model is vaporized, the liq...
