Abstract
The open a kind of Pressure plate of negative pressure lost foam sand box of the present invention, the left side of described pressing plate is formed two loose-leaves, the right edge of described pressing plate is formed two latches, is installed in described negative pressure evanescent mold sand box after described loose-leaf and latch are installed on described negative pressure evanescent mold sand box and then by described pressing plate folding.By the present invention in that after fixing with loose-leaf and latch, pressing plate is just as window, and folding is all very convenient, the replacing of gauze in very convenient sandbox.
Description
Technical field:
The present invention relates to a kind of Pressure plate of negative pressure lost foam sand box, it belongs to casting technology field.
Background technology:
Technology of EPC is by the bonding model cluster that is combined into of foam type similar for casting dimension shape, brushes fireproof coating
And after drying, it being embedded in vibration molding in drystone sand, cast makes model gasify under negative pressure, and liquefaction metal occupies model position
Put, after solidification cooling, form the novel casting method of foundry goods.It is with the dimensional accuracy height of foundry goods, any surface finish, of low pollution
Deng outstanding advantages, more traditional foundry engieering, there is powerful competitiveness, be described as the foundry engieering of 21st century,
The Green revolution of foundary industry.
The pressing plate of the internal fixing gauze of existing negative pressure evanescent mold sand box, as it is shown in figure 1, the pressure on tight flask pressing plate 1
Plate negative pressure ventilation hole 2 is all that hole, hole is relative with bridge screw hole 3 with the passage on sandbox wall 4 and screw hole, passes through spiral shell
Screw in nail fixes pressing plate and negative pressure evanescent mold sand box, but owing to the gauze in sandbox often to be changed, turn round
Open and tighten a lot of screws, when taking a lot of work very much.
Therefore, necessary prior art improves to solve the deficiency of prior art.
Summary of the invention:
The present invention provides a kind of Pressure plate of negative pressure lost foam sand box, and it can effectively improve existing negative pressure evanescent mold sand box and change
The inconvenience of gauze.
The present invention adopts the following technical scheme that a kind of Pressure plate of negative pressure lost foam sand box, is formed on the left side of described pressing plate
Having two loose-leaves, be formed with two latches in the right edge of described pressing plate, described loose-leaf and latch are installed on described negative pressure
It is installed in described negative pressure evanescent mold sand box after evaporative pattern sandbox and then by described pressing plate folding.
Further, some platoon leader's grooves, the orientation of described elongated slot and number it are formed with in the centre position of described pressing plate
Orientation and number according to the passage in described negative pressure evanescent mold sand box are determined.
Further, described elongated slot has two rows, and the number of every platoon leader's groove is 3.
Further, described Pressure plate of negative pressure lost foam sand box is rectangular shape.
After there is advantages that it is by using loose-leaf and latch to fix, pressing plate, just as window, leaves
Close all very convenient, the replacing of gauze in very convenient sandbox.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of Pressure plate of negative pressure lost foam sand box in prior art.
Fig. 2 is the structural representation of Pressure plate of negative pressure lost foam sand box of the present invention.
Detailed description of the invention:
Refer to shown in Fig. 2, the generally rectangular shaped shape of Pressure plate of negative pressure lost foam sand box of the present invention, at the left side of pressing plate 5
On be formed with two loose-leaves 6, the right edge of pressing plate 5 is formed two latches 7, the present invention fixes the pressure of gauze
Plate is not required to fix with being similar to a lot of bridge screw of the prior art, uses loose-leaf 6 instead and latch 7 is fixed, and then keep away
Exempt from the gauze in sandbox often to change, will turn on and tighten inconvenience when taking a lot of work that a lot of screws is caused.Use instead
After loose-leaf and latch are fixed, pressing plate is just as window, and folding is the most very convenient.It is formed with two in the centre position of pressing plate 5
Platoon leader's groove 8, wherein the orientation of elongated slot 8 and number are according to the arrangement side of the passage 10 in negative pressure evanescent mold sand box 9
To and number determined.As the present invention for embodiment in, have two platoon leader's grooves, and the number of every platoon leader's groove be 3.
By the present invention in that after fixing with loose-leaf and latch, pressing plate is just as window, and folding is all very convenient, very convenient
The replacing of gauze in sandbox.Each elongated slot and the several ventilations on sandbox in Pressure plate of negative pressure lost foam sand box the most of the present invention
The corresponding setting in hole, and unlike in the prior art, the passage on pressing plate is all relative with the passage on sandbox wall
Should.After sandbox of the present invention uses, when cleaning, it is not necessary to one hole, a hole is plucked out cleaning, but directly with brush
Gauze corresponding for elongated slot is carried out the most swiped through can cleaning out by son, saves time and facilitates.
The above is only the preferred embodiment of the present invention, it is noted that for those skilled in the art
For, some improvement can also be made under the premise without departing from the principles of the invention, these improvement also should be regarded as the present invention's
Protection domain.
