Abstract

The utility model discloses an extrusion die for a slender rod part. The die comprises an upper die and a lower die, wherein the upper die is provided with an upper die sleeve; a floating die is matched in the upper die sleeve in a sliding manner; an upper die plate is covered on the upper port of the upper die sleeve; an upper punch is fixed on the lower surface of the upper die plate; a spring is arranged between the lower surface of the upper die plate and the floating die; an upper through hole in which the upper punch is conveniently inserted is axially arranged on the floating die; a lower die sleeve is arranged on the lower die; an upper concave die and a lower concave die are arranged in the lower die sleeve; lower through holes are axially arranged in both the upper and lower concave dies; the upper end face of the upper concave die is abutted with the lower end face of the floating die; and a lower ejection rod conveniently inserted in the lower through holes to eject out products is further arranged below the lower die sleeve. The floating die is installed in the upper die sleeve and abutted with the upper concave die through the spring and the self-weight of the floating die, and part of materials are located in the floating die, so that the floating die plays a partial role of the upper concave die and plays a role of completely protecting the upper punch at the same time; furthermore, the ejection amplitude after extruding to finish an opening die is reduced by half and the production efficiency is enhanced. The utility model belongs to the technical field of dies.

Description

The extrusion die of slender rod type part
Technical field
The utility model belongs to technical field of mold, relates to or rather a kind of extrusion die of slender rod type part.
Background technology
In the prior art, the main dual mode that adopts of front slender rod type part contracting bar distortion: the open extruding of the employing that 1, deflection is less, i.e. free diameter reducing, half puts into concave die cavity blank, and second half is exposed at the mould outside, by the descending extruding of upper solid punch.If 2 deflections are larger, then need the elongate rod blank is put into die fully, by a descending sealing extrusion of elongated punch.Outside the extruding punch of this conventional design is exposed to fully, have certain potential safety hazard in the production process, and lower ejection stroke amplitude is large, production efficiency is low.
The utility model content
The technical problems to be solved in the utility model is: a kind of extrusion die safer, the slender rod type part of enhancing productivity that pushes is provided.
Technical solution adopted in the utility model is: a kind of extrusion die of slender rod type part, comprise upper die and lower die, patrix is provided with Upper Die-sleeve, sliding fit has floating die in the Upper Die-sleeve, the Upper Die-sleeve upper port is stamped cope match-plate pattern, the cope match-plate pattern lower surface is fixed with upper punch, is provided with spring between cope match-plate pattern lower surface and the floating die, and floating die is axially arranged with is convenient to the upper through hole that upper punch inserts; Counterdie is provided with lower die-sleeve, be provided with upper cavity die and lower cavity die in the lower die-sleeve, upper cavity die and lower cavity die all are axially arranged with lower through-hole, and upper cavity die upper surface and floating die lower surface offset, and the lower die-sleeve below also is provided with is convenient to insert lower through-hole for the lower push rod that product is ejected.
Described floating die is engaged in and refers in the Upper Die-sleeve that the Upper Die-sleeve lower end screws a nut, and the floating die outer wall has single order halfpace rank to be convenient to hang on the nut inner ring.
The beneficial effects of the utility model are: after adopting above structure; the extrusion die of the utility model slender rod type part is compared with original technology; have the following advantages; adopt the upper and lower mould holder structure, floating die is housed in the Upper Die-sleeve, add the floating die deadweight by spring and fit with upper cavity die; this moment, the part material level was in floating die; the floating die partial action that not only served as upper cavity die plays fully protection simultaneously but also to upper punch like this, also has extruding to finish to eject amplitude after the die sinking to reduce half, enhances productivity.
Description of drawings
Fig. 1 is the utility model schematic diagram.
Shown in the figure: 1, Upper Die-sleeve, 2, cope match-plate pattern, 3, upper punch, 4, spring, 5, nut, 6, floating die, 7, upper cavity die, 8, lower cavity die, 9, the die cushion block, 10, lower push rod, 11, lower die-sleeve.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
With reference to shown in Figure 1, the extrusion die of a kind of slender rod type part of the utility model, comprise upper die and lower die, patrix is provided with Upper Die-sleeve 1, Upper Die-sleeve 1 interior sliding fit has floating die 6, and Upper Die-sleeve 1 upper port is stamped cope match-plate pattern 2, and cope match-plate pattern 2 lower surfaces are fixed with upper punch 3, be provided with spring 4 between cope match-plate pattern 2 lower surfaces and the floating die 6, floating die 6 is axially arranged with is convenient to the upper through hole that upper punch 3 inserts; Counterdie is provided with lower die-sleeve 11, be provided with upper cavity die 7 and lower cavity die 8 in the lower die-sleeve 11, lower cavity die is lined with die supporter piece 98 times, and upper cavity die 7 all is axially arranged with lower through-hole with lower cavity die 8, and upper cavity die 7 is exactly the cavity that shaped article is used with the shape of lower cavity die 8 lower through-hole junctions.Upper cavity die 7 upper surfaces and floating die 6 lower surfaces offset, and lower die-sleeve 11 belows also are provided with is convenient to insert lower through-hole for the lower push rod 10 that product is ejected.During work, lower push rod 10 passes die cushion block 9, lower cavity die 8, upper cavity die 7 from bottom to top successively, then product is ejected.
Described floating die 6 is engaged in and refers in the Upper Die-sleeve 1 that Upper Die-sleeve 1 lower end screws a nut 5, and floating die 6 outer walls have single order halfpace rank to be convenient to hang on nut 5 inner rings.Nut 5 vertical interfaces left half are L-shaped, and outstanding step can hang on the nut 5 on floating die 6 outer walls, and a spacing effect is played in the below.
Operation principle of the present utility model is: before the upper and lower mould matched moulds, workpiece is inserted into from top to bottom in the lower through-hole of upper cavity die 7 and little die 8.Patrix is operation downwards from top to bottom; floating die 6 is housed in the Upper Die-sleeve 1; add floating die 4 deadweights by spring 4; floating die 6 is positioned at bottom; when patrix continued to move downward, inserted in the upper through hole of floating die 6 the workpiece upper end, until fit in floating die 6 lower surfaces and upper cavity die 7 upper surfaces; floating die 6 had both served as the partial action of upper cavity die 7 like this, simultaneously again to 3 fully protections of upper punch.Continue descending in the upper through hole of patrix drive upper punch 3 insertion floating dies 6, the extruding workpiece, deform under the powerful External Force Acting of workpiece, workpiece is extruded pressure in short-term, unnecessary material enters into upper cavity die 7 and lower cavity die 8 lower through-hole junctions, namely reach required form, whole extruding action is all carried out in enclosed cavity, and is safer before comparing.After the formed product, patrix is up, and floating die 6 breaks away from products, and the existing part of product this moment is exposed, so the lower push rod on the counterdie 10 ejects amplitude and can reduce a part, has improved production efficiency.
