(3) summary of the invention
The purpose of this utility model designs in order to overcome above deficiency just that a nested structure is reasonable, external tooth form part extrusion die in the service-strong.
The purpose of this utility model can realize by following measure:
External tooth form part extrusion die comprises punch mechanism, die mechanism and mould tube mechanism in of the present utility model, described punch mechanism comprises last punch and the punch fixed cover that presses together with back taper, be provided with cushion block above it, be fitted in together in the patrix circle, be fixed on above the patrix circle cope match-plate pattern below, patrix circle end opening will be gone up punch, cushion block, punch fixed cover by hold-down nut and be fixed in the patrix circle, and the patrix circle is fixed on cope match-plate pattern, and the cope match-plate pattern two ends are provided with the guide pillar guide pin bushing; Die mechanism is wherein gone up little die and last concave mold pressing splice grafting to touch for combination punch-die mechanism, and down middle die contacts with following little die pressing, place little die and last concave mold pressing component below, contact with the centre circle pressing together; Centre circle combines with press-fit manner with the outer ring, forms die mechanism; Mould tube mechanism comprise cushion block and the center pillar that is installed in bottom in the mould tube and be installed in center pillar and the cushion block centre bore in long push rod and lack push rod; cushion block and another cushion block are installed in the mould tube; lower punch is positioned at the centre bore of cushion block; described combined die mechanism is installed in the internal upper part of mould tube; trim ring and mould tube are suitable for reading fastening, are fixed on above the lower bolster below the mould tube.
Structure of the present utility model in use can be by replacing mould respectively last punch, lower punch, and die promptly realize the extrusion molding of other part.
Punch is an inverted cone shape in the utility model, and punch processing is very convenient, the mode of the fastening employing nut of punch, and lower punch is free movable in recessed module, makes Mould Machining very simple, and required precision is not high, and it is also very convenient to eject.
The utility model has following advantage:
1, punch adopts inverted cone shape.No matter whether the drift complexity to be like this, all make the processing of punch manufacture very facility, and the available line cutting processing, thereby saved mold materials.With the fastening punch of nut, greatly facilitate the replacing of drift, this structure is fit to all punching press and extrusion type part forming.
2, this die is a combined type.The novel replacing conveniently simple in structure, particularly lower punch is movable, conventional lower punch should be fixed in the recessed tool, each part all wants Precision Machining could guarantee and the concentricity of die that assembly precision requires also high, and ejecting mechanism is also complicated, and take free movable lower punch can make Mould Machining very simple, required precision is not high yet, and part ejects very convenient, is particularly suitable for producing in enormous quantities high-precision interior external tooth form part.
(4) description of drawings
Accompanying drawing is that master of the present utility model cuts open figure.
Among the figure 1 be down in die, the 2nd, little die down, the 3rd, lower punch, the 4th, short push rod, the 5th, long push rod, the 6th, center pillar, the 7th, cushion block, the 8th, lower bolster, the 9th, cushion block, the 10th, mould tube, the 11st, cushion block, the 12nd, trim ring, the 13rd, centre circle, the 14th, outer ring, the 15th, guide pillar guide pin bushing, the 16th, cope match-plate pattern, the 17th, hold-down nut, the 18th, last punch, the 19th, cushion block, the 20th, patrix circle, the 21st, the punch fixed cover, the 22nd, go up little die, the 23rd, die in going up.
(5) specific embodiment
The utility model is further described below with reference to embodiment (accompanying drawing):
