Description
Technical field
The utility model relates to a kind of composite hot extrusion die of pull bar.
Background technology
Daily production, the various instrument used in life and product, invariably there is close relationship with mould, and the consumer goods of the overwhelming majority are all plastic products, this product by injection molded out, existing mould is when converted products, normally being watered by the material after fusing casts from mould, after cooling to be formed, the demoulding just can obtain required product, but, mould is when the product that more shaping shaping glue bit comparisons are dark, there will be when product stripping stick on mould, to cause product to rupture cannot the situation of the demoulding smoothly, the extruding of existing pull bar adopts the direct machining of bar to form, stock utilization is low, and waste is serious, production efficiency is low, product strength is low, density is large, the shortcomings such as poor electric conductivity.
Summary of the invention
The technical problems to be solved in the utility model is to provide that a kind of billet size precision of producing is high, and blank is lightweight, the composite hot extrusion die of the easy demoulding and the good pull bar of electrical and thermal conductivity performance.
For solving the problem, the utility model adopts following technical scheme: a kind of composite hot extrusion die of pull bar, comprise cope match-plate pattern, upper padding plate, punch and die, described cope match-plate pattern lower surface is provided with upper padding plate, described upper padding plate lower surface is provided with punch retainer, described punch retainer inside is provided with punch, die is provided with below described punch, described die surrounding is provided with the pre-collar of die, the pre-collar of described die can make the composite hot extrusion die machine structure of pull bar more stable, reduce error, certain headspace is provided with between the pre-collar of described die and punch retainer, described female bottom is provided with ejector, described ejector comprises thimble and push rod, described thimble can be more prone to when the demoulding, described thimble is arranged on the top of push rod, described die lower surface is provided with lower bolster, described lower bolster lower surface is provided with lower bolster.
As preferably, the center line of described die and the center line of punch are positioned at same straight line, and die and punch error is operationally reduced.
As preferably, the length of described push rod is greater than the thickness of lower bolster, and some is in the outer surface of lower bolster to make push rod, is more prone in the demoulding.
As preferably, the length of described lower bolster equals the diameter of the pre-collar of die, and both junctions can be allowed to keep smooth.
As preferably, the pre-collar of described die is the pre-collar of synthetic rubber, ensures that the die pretensioning effect of the pre-collar of die is good.
As preferably, the mating holes in described push rod and lower bolster adopts interference fit, makes not interspace between push rod and lower bolster.
This technical scheme bar portion is instead squeezed, the head thimble mode of production of just squeezing, and makes that billet size precision is high, blank is lightweight, electrical and thermal conductivity performance is good.
The beneficial effects of the utility model are: because described composite hot extrusion die adopts the mode of production that bar portion is instead squeezed, head is just squeezing, make that billet size precision is high, blank is lightweight, electrical and thermal conductivity performance is good, and the structure of this mould is simple, highly versatile, extruding force are little, the wide and easy demoulding of applicability etc.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the schematic diagram of the composite hot extrusion die of this practical pull bar.
Detailed description of the invention
Consult shown in Fig. 1, a kind of composite hot extrusion die of pull bar, comprise cope match-plate pattern 1, upper padding plate 2, punch 4 and die 6, described cope match-plate pattern 1 lower surface is provided with upper padding plate 2, described upper padding plate 2 lower surface is provided with punch retainer 3, described punch retainer 3 inside is provided with punch 4, die 6 is provided with below described punch 4, described die 6 surrounding is provided with the pre-collar 5 of die, certain headspace is provided with between the pre-collar of described die 5 and punch retainer 3, ejector 7 is provided with bottom described die 6, described ejector 7 comprises thimble 11 and push rod 10, described thimble 11 is arranged on the top of push rod 10, described die 6 lower surface is provided with lower bolster 8, described lower bolster 8 lower surface is provided with lower bolster 9, according to extrusion shape, punch 4 is designed to hollow shape, adopt two layers of combined die structure.During extruding, first blank is put into die 6 die cavity, descending along with punch 4, blank is just extruded into shape in combined die 6, and bar portion is counter is simultaneously extruded into shape, along with crimp power increases gradually, when metal forward flow is to ejector 7, head formation terminates, and now metal oppositely continues flowing.After extruding completes, cope match-plate pattern 1 backhaul, workpiece is stayed in die 6, cylinder action under forcing press, by thimble 11, head major diameter part is ejected die 6, can complete the demoulding.Should leave certain gradient between shape and ejector mouth in workpiece head, to ensure that workpiece and ejector locking phenomenon do not occur, push rod 10 doubles as the die 6 of head forward extrusion.
The center line of described die 6 and the center line of punch 4 are positioned at same straight line, ensure the perpendicularity on punch 4 surface during installation.
The length of described push rod 10 is greater than the thickness of lower bolster 9, and push rod 10 grows lower bolster 9 part in use.
The length of described lower bolster 2 equals the diameter of the pre-collar 5 of die.
The pre-collar of described die 5 is the pre-collar of synthetic rubber, and the pre-collar 5 of described die is vertically fitted in the surface of die 6.
Described push rod 10 adopts interference fit with the mating holes in lower bolster 9, and the requirement according to reality also can adopt interference fits.
In use material shaping in composite hot extrusion die after, the same with the diameter of punch 4 internal cavity at cope match-plate pattern 1, upper padding plate 2, drive the thimble 11 recessed place arriving punch 4 that moves to block by extruding push rod 10, namely can extrude finished product fast.
The beneficial effects of the utility model are: because described composite hot extrusion die adopts the mode of production that bar portion is instead squeezed, head is just squeezing, make that billet size precision is high, blank is lightweight, electrical and thermal conductivity performance is good, and the structure of this mould is simple, highly versatile, extruding force are little, applicability is wide and the easy demoulding etc.
The above, be only detailed description of the invention of the present utility model, but protection domain of the present utility model is not limited thereto, and any change of expecting without creative work or replacement, all should be encompassed within protection domain of the present utility model.Therefore, the protection domain that protection domain of the present utility model should limit with claims is as the criterion.
