Description

Casting sand mold molding machine

The utility model relates to a kind of moulding machine of making casting mold.

On most employing that the mold industry is actually used in the mold founding is furnished with by the operator, workpiece such as low mold frame and platform is implemented, be that the operator will wait that the model of casting thing is put on the platform, low mold frame is placed on the model, and in low mold frame, tamp and bury multiple model with molding sand, again low mold frame is overturn, the molding sand of seeing model is faced up, to go up then and framedly be sleeved on the low mold frame down, and give plant one earlier and water rod, to be made for the cast gate in when casting, in upper ledge, tamp again and bury multiple model with molding sand, extract subsequently and water rod, and will go up framed disengaging low mold frame, the loosening gradually again model that buries on the molding sand face that takes out.At this moment, more than, leave over the die cavity that remains as cast molding in the sand mo(u)ld of low mold frame molding sand moulding.

Above-mentioned embodiment, at certain manpower, under man-hour, it is extremely limited that it finishes the sand mo(u)ld amount, not only labor intensive and time, and suitable trouble, be the society of prerequisite to striving for economic benefits now, its operating efficiency has not had its value.

The purpose of this utility model is to provide a kind of facility, the casting sand mold molding machine of the integral matching structure of sand mold molding fast, with order output and its efficiency of construction that improves sand mo(u)ld.

The utility model is finished like this: the front end on a support is provided with a ∏ type track base, there be a pair of upper and lower framed group to drive along each free its corresponding oil pump of the guide rail plate in the track base and to do upper and lower lifting, there is a jacking group its underpart, and the oil pump below it drives so that sand mold is ejected from framed group; Have into sand beat the pressure group on upper and lower framed group top, this group is beaten the pressure box body, and sand-feeding tube is arranged on the box, and the door of shaking out is arranged at the bottom, and drive to following by its oil pump and irritate molding sand in framed, and can to beat pressure solid to filling framed group of molding sand.

The rear end of support is provided with template feeding pedestal, is divided into the vertical lifting of template traverse feed group and template and gives, and does forward and backward moving and upper and lower lifting by oil pump drive template separately, and template is pushed framed middle system type, after the system type finishes, withdraws from wait and casts.

The utility model compared with the prior art, its advantage is:

1, in the production process, can effectively save manpower, reduce man-hour;

2, the sand mo(u)ld yield rate greatly improves, and the casting quality is improved effectively;

3, at certain manpower, under man-hour, sand mo(u)ld output significantly improves, cost descends relatively;

4, the operator need not carry out the framed heavy physical labours such as mould that turn over.

Template 7 inserts in the upper and lower pressing plate 684 of cantilever 68 and 685, its plate face appropriate location is placed and is treated the mold entity, is inserted with a gate stick 71 on the model 70, and the left and right side of plate face has for the interspersed hole 72 of the reference column of low mold frame 31 left and right sides, in addition, the rear side of template 7 also is provided with a vibrator 73.

The utility model assembles through above-mentioned each parts, its specific embodiment such as Fig. 5,6,7; On, on the low mold frame group 3 framed 30, low mold frame 31 and advance sand and beat pressure group 5 respectively through its

oil pump bar

33,35 and 52 drive, rise to the position (being initial point) that sets, (annotate: advance sand this moment and beat the door-plate 56 and 57 of pressure group 5 and be open state, and advance sand and beat the door-plate 56 and 57 of pressure group 5 and have only) when advancing just to present open shape when sand is beaten pressure group 5 at origin position, the plate 40 of putting with jacking group 4 places height to call together on 10 the aperture 11 again, low mold frame 31 is again in paramount 10 of oil pump bar 35 driving decline, subsequently, cartridge starts, molding sand in the tube advances sand by sand-feeding tube 51 and falls in the low mold frame 31, up to molding sand flood cover low mold frame 31 till.

Template 7 stops via oil pump bar 64 driving shift-in to low mold frame 31 tops of template traverse feed group 60, driving the position that drops to the about 2mm in low mold frame 31 tops via the oil pump bar 67 of vertical lifting group 61 again stops, heir and last framed 30 is driven decline again, and compressing template 7 decline 2mm, sand-feeding tube 51 is multiple to be advanced sand again and floods and be covered with framed 30, advancing sand afterwards beats pressure group 5 and drives to descend through its oil pump bar 52 and beat the molding sand that presses framed 30 in and (beat pressure group 5 and descend gradually owing to advancing sand, sand-feeding tube no longer forces door-plate 56 and 57 to be opened gradually, so door-plate 56 and 57 is able to gradually to beat the decline of pressure group 5 and cut out with advancing sand), and the plate 40 of putting of jacking group 4 drives rising jacking low mold frame 31 through its oil pump cash 41, and template 7 is started by vibrator 73 and does the appropriateness vibration afterwards.Molding sand in upper and lower framed 30,31 is promptly stopped after evenly, advance sand simultaneously and beat beating of pressure group 5 and press the molding sand that plate 40 continues in compressing, the jacking upper and lower framed 30 and 31 of putting of box body 50 and jacking group 4 to make molding sand more closely knit.

Then, the vibrator 73 of template 7 vibrates once more, make the model 70 on the template 7 slightly take off the molding sand layer that moves in the frame, and then advance sand and beat pressure group 52 and be driven to rise and leave framed 30 and be returned to initial point, going up framed 30 is driven immediately again and rises to one and suitably highly promptly stop, and template 7 drives successively respectively through vertically lifting group 61 and traverse feed group 60 and rises, retreats, and treats that template 7 keeps in the center, and goes up framed 30 tops that are driven and press to low mold frame 31 again; Because prior art has had the setting of upper and lower framed sand block sheet, at sand mold molding, after template breaks away from upper and lower molding sand layer, being about to framed sand block sheet pulls open, upper and lowerly framedly can break away from sand mo(u)ld automatically, be taken out framed and only stay sand mo(u)ld, drive through

oil pump bar

33 and 35 again, upper and lower framedly rise once more, the sand mo(u)ld of casting usefulness are promptly kept somewhere in putting to be waited on the plate 40 and shifts out casting.
