Description
Technical field
The present invention relates to mold forming fields, in particular, being related to a kind of for the coating liquid on the molded surface of mold
The coating unit of body.
Background technique
Before manufacturing blade, need to clean the surface of blade mold, sealing of hole and wiping release agent (hole sealing agent or
Clean mould agent) etc. operations.Currently, general wipe release agent by the way of manual.It is specific that there are two types of the mode of wiping, one of which sides
Formula includes the following steps: that personnel wear protective articles then cotton is screwed onto cotton dipping release agent just without release agent to
Drop drip, then using spiral (or axial direction and chordwise direction right-angled intersection formula along mold) by hand to entire blade
Mold is wiped, this mode large labor intensity, fatiguability；Another way wipes release agent using cotton package mop,
This mode release agent consumption is big.
In addition, if operating personnel's careful degree in operation process is insufficient, then the problems such as being easy to appear few painting, holiday,
Cause wiping effect bad, thus may result in blade demoulding when there is a phenomenon where sticking to moulds, cause mold or blade surface
Damage.The method of the wiping effect of detection release agent is that U.S. line paper is sticked to blade mould after the release agent wait wipe is dry at present
U.S. line paper is lightly removed on the surface of tool, if U.S. line paper is easy to fall off, shows that stripping result is good, if U.S. line paper is not allowed
It is easy to fall off, then show that stripping result is bad.There are many this qualitative detection method accidentalia, it is difficult to accurately judge release agent
Whether coat uniformly.
Therefore, current wiping mode at least has the disadvantage that pure wiping by hand to labor protection articles and release agent
Deng waste than more serious；Since release agent is biochemical preparation, come close to or in contact with release agent operating personnel can be caused it is certain
Harm；Pure manual work inefficiency, time consumption are very big；The molded surface of mold is usually curved surface, and operating personnel is in type chamber
It substantially kneels (crouching) when interior operation to wipe on the molded surface of mold, region especially bigger in curvature, operation is difficult
Degree is big, needs support staff's integration of operation, and operating personnel kneels (crouching) formula operation for a long time, and body is also easy to produce fatigue；Operating personnel
Holiday or overbrushing are easy in wiping process, and the dosage of the release agent on cotton is also difficult to control, and is easy to cause release agent
The phenomenon that equal reagents wiping is uneven, and wiping effect is bad, and sticking to mould is easy to happen when thus blade being caused to demould；Existing wiping
Effect detection belongs to qualitative detection, and there are many accidentalia, it is difficult to accurately judge the coating thickness of release agent.

Specific embodiment
Hereinafter, the preferred embodiment of the present invention is described in detail with reference to the attached drawings.It should be noted that the explanation of embodiment below
In attached drawing, identical label always shows identical component, and the repetitive description thereof will be omitted.
The coating unit of embodiment according to the present invention can be used for coating release agent on the molded surface of mold, can also
For coating other various liquid.
Fig. 1 is the perspective view of the coating unit of embodiment according to the present invention, and Fig. 2 is the painting of embodiment according to the present invention
The side view of coating device.
As depicted in figs. 1 and 2, coating unit 1 may include main body 10 and the brush head connecting with main body 10 20.Main body 10 can be with
It is that there is the box body of inner containment cavity, and may include the storage case 11 for accommodating coating liquid, coating liquid can be for leaf
The hole sealing agent of sheet mold, clean mould agent, release agent etc. will be coated in the various applying liquids on the molded surface of blade mold.Hold
Case 11 of receiving can be fixed in main body 10, can also be disassembled from main body 10, in order to safeguard, replace or clean.In this hair
In bright exemplary embodiment, storage case 11 is arranged in the main body 10.
Brush head 20 can be movably arranged on the bottom of main body 10, brush head 20 coating liquid can be coated in blade mold at
On type surface.Brush head 20 can receive coating liquid from storage case 11 via first runner, may also set up inside stream inside brush head 20
Road, coating liquid flow to the bottom of brush head 20 by inner flow passage, are then applied on the molded surface of blade mold.
Brush head 20 can be mill, for example, circular millstone, can wind or coat the flexibility of absorbable coating liquid on mill
Fabric, for example, can wind or coat sponge or cotton etc. on mill.
Coating liquid is smeared using brush head 20 by using coating unit 1, can directly contact coating liquid to avoid operating personnel
(for example, release agent), or close to coating surface, coating liquid is reduced to the potential hazard of human body.
Coating unit 1 may include control unit, which can control the flow velocity or flow of coating liquid, to control painting
Cover thickness.For example, the aperture for the valve (for example, solenoid valve) that control unit can be arranged on first runner by control, comes
Control the flow or flow velocity of coating liquid.
Coating unit 1 may also include thermal wave imaging test section 30, and thermal wave imaging test section 30 can detecte coating liquid in leaf
Coating thickness on the molded surface of sheet mold, and export detection data.Coating unit 1 uses thermal wave imagine technique, Ke Yigeng
The coating thickness of coating liquid is accurately detected, so as to accurately control the flow or flow velocity of coating liquid according to testing result, and
The coating thickness of each region is set to keep uniformity.
Thermal wave imaging test section 30 can will test data by wired or wireless mode and be output to control unit and show
Show unit (for example, display hereinafter).Thermal wave imaging test section 30 can be according to mold theoretical model and real-time detection
Heat wave signal obtain coating thickness of the coating liquid on mold.
For example, thermal wave imaging test section 30 can progressively scan the heat of the molded surface of the blade mold coated with coating liquid
Then wave signal is fitted with mold former, to obtain the curve that the heat wave signal changes over time to be applied again
Cover thickness.Here, thermal wave imaging test section 30 can be used to exist in advance for mold former (especially, the model of the molded surface of mold)
It does not coat and executes heat wave scanning on the molded surface of the blade mold of release agent to obtain.
Embodiment according to the present utility model, thermal wave imaging test section 30 can be based on pre-stored mold theoretical model
And the heat wave signal of real-time detection obtains coating thickness.It is therefore not necessary to detect mould in advance using thermal wave imaging test section 30
The model of tool shortens coating time.
