Abstract
The invention discloses a locking mechanism for a sand mould supporting plate. The locking mechanism comprises a pair of locking devices positioned on two sides of a lower sand box, wherein the pair of locking devices has the same structure and comprises a locking air cylinder respectively; one end of a bracing plate is fixed on piston rods of the locking air cylinders and the other end of the bracing plate is fixedly connected with a push rod; the push rod is fixedly connected with a locking fork plate; and one fork end of the locking fork plate is positioned on the lower sand box and used for locking the sand mould supporting plate, and the other fork end of the locking fork plate is connected with a resetting spring through a spring guide rod. The locking mechanism for the sand mould supporting plate is applied to a molding machine of a continuous production line of a casting department so as to realize semi-automatic production of the molding machine; therefore, the production rate is increased and the labor intensity of a molder is reduced.
Description
Technical field
The invention belongs to the foundry work field, relate to a kind of sliding off type sand box of moulding machine, relate to specifically a kind of for the locking mechanism for sand mould supporting plate of locking sliding off type sand box with sand mould supporting plate.
Background technology
Known, little is on tinuous production, makes sand mold with moulding machine.The drag box 8 of sliding off type sand box is upper, after injecting molding sand from sand hopper, and the molding sand (see figure 1) that the jolting cylinder vibrations of moulding machine and ram-jolt drag box are 8 li, then put sand mould supporting plate 7.Then, the hand rest sandbox holder hand 11 of staying relies on the workbench of moulding machine to come anti-case, makes above cope 9 translates into.Again the molding sand in sand hopper is injected cope 9, use at last the molding sand (see figure 2) in squeezing cylinder compacting cope.After playing cope 9, play template 10, then cope 9 is incorporated into drag box 8.After drawing, being put into the sand mold of making little is on mould carriage.This kind moulding machine is when work, and productivity ratio efficient is lower, and moulder's labour intensity is high.
Summary of the invention
For overcoming deficiency of the prior art, the object of the present invention is to provide a kind of locking mechanism for sand mould supporting plate, utilize this mechanism can realize the semi-automatic production of moulding machine, to enhance productivity, reduce moulder labourer's intensity.
For solving the problems of the technologies described above, realize above-mentioned technique effect, the present invention is achieved through the following technical solutions:
A kind of locking mechanism for sand mould supporting plate, comprise a pair of locking device that is positioned at the drag box both sides, described a pair of locking device structure is identical, comprise respectively a locking cylinder, one end of one fagging is fixed on the piston rod of described locking cylinder, the other end push rod that is connected, the described push rod locking fork plate that is connected, one fork of described locking fork plate is positioned at and is used for the locking sand mould supporting plate on drag box, and another fork is connected with a back-moving spring by a spring guide.
Further, a fork of described locking fork plate is positioned at the gathering sill that is opened on described drag box.
Compared with prior art, the present invention has following beneficial effect:
Locking mechanism for sand mould supporting plate of the present invention can be realized the semi-automatic production of moulding machine after being applied on the moulding machine of foundry shop's tinuous production, has improved productivity ratio and has alleviated moulder's labour intensity.
Above-mentioned explanation is only the general introduction of technical solution of the present invention, for can clearer understanding technological means of the present invention, and can be implemented according to the content of specification, below with preferred embodiment of the present invention and coordinate accompanying drawing to be described in detail as follows.The specific embodiment of the present invention is provided in detail by following examples and accompanying drawing thereof.
Description of drawings
Accompanying drawing described herein is used to provide a further understanding of the present invention, consists of the application's a part, and illustrative examples of the present invention and explanation thereof are used for explaining the present invention, do not consist of improper restriction of the present invention.In the accompanying drawings:
Fig. 1 is the structural representation of the drag box situation up of sliding off type sand box in prior art.
Fig. 2 is the structural representation of the cope situation up of sliding off type sand box in prior art.
Fig. 3 is the sliding off type sand box that locking mechanism for sand mould supporting plate of the present invention is installed, the structural representation of drag box situation up.

Number in the figure explanation: 1, locking cylinder, 2, fagging, 3, push rod, 4, locking fork plate, 5, back-moving spring, 6, spring guide, 7, sand mould supporting plate, 8, drag box, 9, cope, 10, template, 11, drag box holder hand.
The specific embodiment
Referring to Fig. 3, shown in Figure 4, a kind of locking mechanism for sand mould supporting plate, comprise a pair of locking device that is positioned at the drag box both sides, described a pair of locking device structure is identical, comprises that respectively an end of locking cylinder 1, one fagging 2 is fixed on the piston rod of described locking cylinder 1, the other end push rod 3 that is connected, the described push rod 3 locking fork plate 4 that is connected, a fork of described locking fork plate 4 is positioned at and is used for the locking sand mould supporting plate on drag box, and another fork is connected with a back-moving spring 5 by a spring guide 6.
Further, a fork of described locking fork plate 4 is positioned at the gathering sill that is opened on described drag box.
Below briefly introduce operation principle of the present invention:
The drag box 8 of sliding off type sand box is upper, after injecting molding sand from sand hopper, and the molding sand (see figure 3) that the jolting cylinder vibrations of moulding machine and ram-jolt drag box are 8 li, then put sand mould supporting plate 7.
At this moment, repaking mechanism moves upward after 10mm, contacts with the drag box holder hand 11 of sliding off type sand box, drives sliding off type sand box and moves upward.Locking cylinder 1 is to be fixed on the base of repaking mechanism, moves with repaking mechanism.When repaking mechanism moved to extreme position, the piston rod of locking cylinder 1 drives fagging 2 and push rod 3 promotes 4 motions of locking fork plate, thereby locked sand mould supporting plate 7.Have two gathering sills on drag box 8, the slip of guiding locking fork plate 4.
With handgrip sliding off type sand box Rotate 180 degree, above at this moment cope 9 forwarded to, drag box 8 is (see figure 4) below.Repaking mechanism moves downward, and breaks away from drag box holder hand 11.The workbench of the drag box 8 contact molding machines of sliding off type sand box.Locking cylinder 1 counter motion, locking fork plate 4 breaks away from sand mould supporting plate 7 under the effect of back-moving spring 5.
Molding sand is injected cope 9, then pass through the molding sand of 9 li of squeezing cylinder compacting copes.After playing top box, play template 10, then cope 9 is incorporated into drag box 8.After drawing, being put into the sand mold of making little is on mould carriage.
Above-described embodiment just is to allow the one of ordinary skilled in the art can understand content of the present invention and implement according to this for technical conceive of the present invention and characteristics being described, its objective is, can not limit protection scope of the present invention with this.Variation or the modification of every equivalence that the essence of content has been done according to the present invention all should be encompassed in protection scope of the present invention.
