Abstract
The invention discloses a negative-pressure evanescent mold sand box pressing plate. Two hinges are formed on the left side edge of the pressing plate; two bolts are formed at the right side edge of the pressing plate; a plurality of long grooves are formed in the middle part of the pressing plate; the arrangement direction and the number of the long grooves are determined according to the arrangement direction and the number of ventilation holes in a negative-pressure evanescent mold sand box. According to the invention, small holes in the negative-pressure evanescent mold sand box pressing plate are changed into long grooves, the pressing plate can be cleaned clearly by brushing lightly by a brush, and time is saved, and the pressing plate is clean.
Description
Technical field
The present invention relates to a kind of negative pressure lost foam sandbox pressing plate, it belongs to casting technology field.
Background technology
Technology of EPC is by the bonding foam type similar casting dimension shape model cluster that is combined into, brush after fireproof coating oven dry, be embedded in vibration molding in dry quartz sand, under negative pressure, cast makes model gasification, liquefaction metal occupies modal position, solidifies the novel casting method of cooling rear formation foundry goods.The outstanding advantages such as it is high with the dimensional accuracy of foundry goods, any surface finish, of low pollution, more traditional foundry engieering, has powerful competitiveness, is described as the foundry engieering of 21st century, the green revolution of foundary industry.
The pressing plate of the inner fixing gauze of existing negative pressure lost foam sandbox, as shown in Figure 1, pressing plate negative pressure ventilation hole 2 on tight flask pressing plate 1 is all that hole, hole is relative with bridge screw hole 3 with passage and screw hole on sandbox wall 4, after sandbox uses, dust sky in sand is easily adsorbed on the gauze in aperture, during cleaning, must pluck out to Yi Ge hole, a hole.Both lost time like this, and cleaning not being very clean.
Therefore, the necessary deficiency of prior art being improved to solve prior art.
Summary of the invention
The invention provides a kind of negative pressure lost foam sandbox pressing plate, inconvenience when it can effectively improve existing negative pressure lost foam sandbox cleaning.
The present invention adopts following technical scheme: a kind of negative pressure lost foam sandbox pressing plate, in the centre position of described pressing plate, be formed with some platoon leader's grooves, the orientation of described elongated slot and number determine according to orientation and the number of the passage in described negative pressure lost foam sandbox.
Further, described elongated slot has two rows, and the number of every platoon leader's groove is 3.
Further, described negative pressure lost foam sandbox pressing plate is rectangular shape.
Further, on the limit, left side of described pressing plate, be formed with two loose-leaves, in the right edge of pressing plate, be formed with two latches.
The present invention has following beneficial effect: it is by making the aperture on existing negative pressure lost foam sandbox pressing plate into elongated slot, as long as take brush just to brush gently and can clean out, saves time and clean.
Accompanying drawing explanation
Fig. 1 is the structural representation of negative pressure lost foam sandbox pressing plate in prior art.
Fig. 2 is the structural representation of negative pressure lost foam sandbox pressing plate of the present invention.
The specific embodiment
Please refer to shown in Fig. 2, roughly rectangular shaped of negative pressure lost foam sandbox pressing plate of the present invention, on the limit, left side of pressing plate 5, be formed with two loose-leaves 6, in the right edge of pressing plate 5, be formed with two latches 7, the pressing plate of fixing gauze in the present invention does not need to fix with being similar to a lot of bridge screw of the prior art, use loose-leaf 6 and latch 7 instead fixing, and then avoid the gauze in sandbox often to change, the inconvenience in the time of turning on and tighten taking a lot of work that a lot of screws causes.Use instead loose-leaf and latch fixing after, fixed head is just as window, folding is all very convenient.In the centre position of pressing plate 6, be formed with two platoon leader's grooves 8, wherein the orientation of elongated slot 8 and number determine according to orientation and the number of the passage 10 in negative pressure lost foam sandbox 9.As the present invention for embodiment in, have two platoon leader's grooves, and the number of every platoon leader's groove is 3.
Each elongated slot and the corresponding setting of several passages on sandbox in negative pressure lost foam sandbox pressing plate of the present invention, and in prior art, the passage on pressing plate is all corresponding with the passage on sandbox wall.After sandbox of the present invention uses, in the time of cleaning, do not need by Yi Ge hole, a hole pluck out cleaning, but directly with brush, gauze corresponding elongated slot was brushed gently and can be cleaned out, save time and facilitate.
The above is only the preferred embodiment of the present invention, it should be pointed out that for those skilled in the art, can also make under the premise without departing from the principles of the invention some improvement, and these improve and also should be considered as protection scope of the present invention.
