Description

Mold sealing device

Technical field

The utility model belongs to the mechanical implement technical field of coating barrier material or the like, specifically discloses a kind of mould Has sealing device.

Background technique

Mold is generally divided into upper mold and lower mold, since upper mold and lower mold are respectively independent component, When being cast, after upper mold and lower mold split, just there is gap between upper mold and lower mold, when molten metal injects mold After interior, if the gap between upper mold and lower mold is not sealed, it will lead to molten metal and pass through upper mold and lower mold Between gap outflow, cause casting flaw, or even casting failure.

And currently, being usually to pass through worker to use brush, adherency for the sealing in the gap between upper mold and lower mold Lute, then to the seam crossing brush seals mud of upper mold and lower mold, so that the gap between upper mold and lower mold is close Sealing clay blocks, to realize sealing, such mode, worker needs repeatedly adherency lute, is repeatedly brushed, low efficiency Under.

Utility model content

The utility model discloses a kind of mold sealing devices, it is therefore intended that at present worker by brush to upper mold under When mold seam crossing brush seals mud, it is low to need repeatedly to adhere to painting efficiency caused by lute is repeatedly brushed again Problem.

The base case of the utility model are as follows: mold sealing device, including casing, casing are equipped with and protrude into for mold flanges Recess, recess sidewall is equipped with rolled portion, and rolled portion rolled by the frictional force drives between mold flanges, notched side It is additionally provided with applying portion on wall, is equipped in casing for drawing fluid into casing and making fluid to go out liquid machine for what applying portion soaked Structure, liquid outlet mechanism are driven by rolled portion.

The technical principle and beneficial effect of the utility model are: staff is by by flange alignment recess, then edge The mobile present apparatus of mold flanges, by the frictional force between rolled portion and flange so that rolled portion rotates, the rotation of rolled portion Lute is sucked in casing and soaks applying portion by driving liquid outlet mechanism, while so that the present apparatus is moved along mold flanges By applying portion by lute brushing at flanged seam, avoid the molten metal in mold from flowing out.Hand compared to the prior art Work brushing, for the present apparatus using more convenient, painting efficiency is higher, repeatedly removes viscous lute with brush without staff.

Further, the liquid outlet mechanism include liquid storage chamber, with the sleeve of liquid storage chamber connection and the transmission that is connect with rolled portion Portion, driving section can the portion of being scrolled driving and rotate, piston plate is slidingly and sealingly connected in sleeve, piston plate is far from driving section one The sleeve of side is connected to liquid storage chamber, and piston plate and liquid storage chamber connectivity part are equipped with elastic membrane, the piston plate driven by driving section and Linear reciprocating motion is done in sleeve.By above-mentioned design, the rotation of rolled portion is transferred on piston plate by driving section, and is made It obtains piston plate and does straight reciprocating motion, so that the pressure in sleeve constantly increases and reduces, so that elastic membrane is continuous Protrusion and contraction so that the pressure in liquid storage chamber constantly increases and reduces, to be drawn and be discharged to lute.

Further, the driving section includes shaft, casing, transmission shaft and reciprocal lead screw, side of the casing far from rolled portion It is provided with blind hole along axial direction, transmission shaft is slidably connected in blind hole by feather key, and the feather key is for avoiding transmission shaft and casing from sending out It is raw to relatively rotate, it is connected between shaft and casing and by universal joint between transmission shaft and reciprocal lead screw, reciprocal lead screw and work Seben is threadedly coupled, and shaft is fixedly connected and is connected to rolled portion at the rolling axle center of rolled portion, between piston plate and sleeve Equipped with the feather key for avoiding piston plate from rotating, the one end of the reciprocal lead screw far from shaft and casing are rotatablely connected, and described turn Axis is equipped with far from one end of reciprocal lead screw makes the adjustable relocation mechanism in rolled portion position.By above-mentioned design, so that working as the present apparatus When for different molds, since mold flanges thickness is different, make the position of rolled portion adjustable by relocation mechanism, in turn Suitable for the flange of different-thickness, and being slidably connected by casing and transmission shaft, avoid the transmitting that ensure that power.

Further, the relocation mechanism is included out in slidably connecting axis in the strip through-hole on enclosure wall, strip through-hole Hold, shaft and brearing bore are interference fitted, and shaft is equipped with positive stop lug boss far from one end of rolled portion, bearing and strip through-hole wall it Between be equipped with elastic component.By above-mentioned design, the elastic force for shaft being slided in strip through-hole, and being applied by elastic component So that rolled portion is tightly attached on flange always, guarantee the frictional force between rolled portion and flange.

Further, the applying portion is located in the recess sidewall for constituting liquid storage cavity wall, and applying portion is located at outside liquid storage chamber, institute It states liquid storage chamber and is equipped with inlet tube far from the one side wall of applying portion, being equipped in inlet tube only allows liquid to enter the list in liquid storage chamber To valve, be additionally provided with baffle in the liquid storage chamber, baffle separates the recess sidewall for being equipped with applying portion with liquid storage chamber, and baffle with set Have there are gap between the recess sidewall of applying portion, baffle is equipped with liquid outlet, and being equipped in liquid outlet only allows liquid to flow out storage The check valve of sap cavity, the recess sidewall equipped with applying portion are equipped with fluid hole, and the applying portion is around around fluid hole.Pass through Lute is sucked liquid storage chamber by inlet tube when so that pressure reducing in liquid storage chamber by above-mentioned design, and pressure increases in liquid storage chamber When, lute in liquid storage chamber is entered in the gap between baffle and recess sidewall equipped with applying portion by liquid outlet, then is led to It crosses fluid hole to flow to outside casing, so that adhering to lute in applying portion.

Further, the applying portion is bristle, and the rolled portion is idler wheel.By above-mentioned design, so that lute passes through Bristle is equably brushed at flanged seam, guarantees the steady of present apparatus movement by idler wheel.
