Description
Technical field
The present invention relates to sand mo(u)ld and make field, be specially a kind of device making fuel pump impeller sand mo(u)ld.
Background technology
In the manufacturing process of sand mold casting mold, first need to carry out moulding to casting model powder.In a moulding mould, load casting model powder, then extrude, sand body is bonded together formation sand mold mould.For the ease of dismounting, moulding mould is generally all divided into bed die and side form, then by fixture, side form and bed die is interfixed.Industrial technology was undeveloped in the past, and filling casting model powder and compacting work are all manual operations, and when compacting, casting model powder produces smaller perpendicular to the pressure in side template face to side form, only needed the connection adopting simple bearing pin and pin-and-hole to match just can fix side form.But along with the development of industrial technology, the especially application of hydraulic technique, now to the compacting of casting model powder be all adopt hydraulic test.During the sand mold mould especially needing making thickness larger, need larger pressure to the compacting of casting model powder, the utilization of hydraulic test just in time meets this requirement.Meanwhile, casting model powder can produce larger power to the fixture of side form, if or the mode adopting bearing pin to match with pin-and-hole, the wearing and tearing of bearing pin and pin-and-hole when simultaneously in addition operating, will soon make the connection of side form produce and loosen.This just just has higher requirement to the fixture of side form, well can fix side form, can not connection be made to loosen because of the wearing and tearing used again.
summary of the invention
The object of this invention is to provide a kind of device making fuel pump impeller sand mo(u)ld, produce loosening problem with the fixture solving mould because of wearing and tearing.
To achieve these goals, a kind of device making fuel pump impeller sand mo(u)ld provided by the invention, comprise side form, bed die and fixture, described side form is connected with bed die by fixture; Described fixture comprises column, jig, fastening screw and bearing, and this bearing is positioned at the outside of side form, and is fixedly connected with side form; This bearing is provided with hole clipping, and described jig is positioned at bearing upper end; And jig and bearing upper end are slidably connected; Described fastening screw to be positioned at outside jig and to be fixedly connected with jig, and this fastening screw is provided with adjusting nut and adjusting nut and bearing offset; This column is fixedly connected with bed die; And column passes hole clipping and offsets with jig.
Compared with prior art, the advantage of this programme is: by arranging the column be fixedly connected with it and the bearing being provided with the hole clipping corresponding with column on bed die, bearing is fixedly connected on side form, thus make side form can observe column by hole clipping whether targeted by hole clipping when installing location, installation is located and more easily operates; By arranging the jig that can slide on bearing, jig is connected with bearing by fastening screw, fastening screw is provided with the nut offseted with bearing, the glide direction of jig on bearing and distance is controlled by adjusting nut, thus realize jig offset with column or from state, thus can not because of use wearing and tearing make connection produce loosen.
As preferred scheme, described jig comprises level board and riser, and riser is located between level board and column, and the shape of this riser is mated with the shape of cross section of column.Be conducive to after gusset and column offset, can with the displacement of limit three horizontal directions.
As preferred scheme, described level board is provided with bar hole, and the length direction of this bar hole is parallel with the axis direction of fastening screw, and described bearing is provided with the bolt matched with bar hole.Be convenient to make the direction of motion of level board identical with the direction of motion of fastening screw, be conducive to making the effect of adjustment the most obvious; Connected by bolt simultaneously, easy for removal and installation.
As preferred scheme, the cross section of described column is triangle.Be conducive to the production material saving column.
As preferred scheme, the bottom of described column is provided with the sole with column axes normal, and this sole and riser are positioned at the homonymy of column, and this sole is connected with bed die by bolt.During fixture work, what the link of column and bearing mainly bore is moment of flexure, is beneficial to simplification structure by such being provided with.
Accompanying drawing explanation
Fig. 1 is the top view that the present invention makes the structural representation of the device of fuel pump impeller sand mo(u)ld;
Fig. 2 is the front view that the present invention makes the structural representation of the device of fuel pump impeller sand mo(u)ld.
Detailed description of the invention
Below in conjunction with drawings and Examples, technical solution of the present invention is further illustrated:
In figure: side form 1, bearing 2, bar hole 3, bolt 4, level board 5, column 6, riser 7, adjusting nut 8, block 9, fastening screw 10, sole 11, fastening bolt 12, bed die 13, hole clipping 14.
The device of making fuel pump impeller sand mo(u)ld is as depicted in figs. 1 and 2 known, is welded with the bearing 2 that shape is cuboid in the middle part of the arranged on left and right sides of side form 1, and the middle part of bearing 2 is provided with the rectangular hole clipping of shape 14, is provided with block 9 in the right part of bearing 2.Block 9 is one-body molded with bearing 2, and the center of block 9 is provided with through hole.The top of bearing 2 is provided with the level board 5 of rectangle, and the forward and backward two ends of level board 5 are provided with bar hole 3.Bearing 2 is provided with the bolt 4 matched with bar hole 3, and level board 5 is coordinated by bar hole 3 and bolt 4 and realizes and being slidably connected of bearing 2.The left side central portion of level board 5 has the groove of " V " font, is welded with the riser 7 that shape matches with it in groove.The column 6 that the left side wall of riser 7 is triangular in shape with the shape of cross section through hole clipping 14 offsets.Weld with fastening screw 10 in the middle part of the right-hand member of level board 5.The right part of fastening screw 10 passes the through hole of block 9, and fastening screw 10 part be positioned on the left of block 9 is provided with adjusting nut 8.The bottom welding of column 6 has sole 11, and the left side of sole 11 flushes with the edge of column 6, and the right part of sole 11 is connected by fastening bolt 12 with bed die 13.
