Abstract
The invention relates to a die, in particular to an impact extrusion die for a screw cap. The impact extrusion die comprises a lower die carrier and an upper die carrier. A strip is put in a discharging plate and positioned by a positioning pin, the upper die carrier descends, a male die starts to be contacted with the strip and interacts with a male connector of a female die to complete blanking of workblank materials, then with continuous descending of the upper die part, the male die continuously pushes the workblank materials to move downwards to complete primary extrusion processing of the workblank materials under the combined action of the female die and an ejector rod, and a semi-finished product is formed; when the upper die carrier descends continuously, the semi-finished product is pushed into a cavity for secondary extrusion processing to realize forming of the screw cap. The die is particularly suitable for manufacturing massive screw caps, and the produced screw cap is good in quality, high in structural strength and good in toughness.
Description
Technical field
The present invention relates to it is related to mould, more particularly to a kind of nut impact extrusion mould.
Background technology
Existing nut machine-shaping is required for being extruded using many molds and just can complete operation, develops a set of required
Die price it is expensive, and bring multiple working procedure very loaded down with trivial details to producing nut in enormous quantities.
The content of the invention
In order to solve above-mentioned technical problem, a kind of nut impact extrusion mould that the present invention is provided.It is particularly suited for large batch of
Nut is manufactured, and the nut quality produced is good, and structural strength is high, good toughness.
The present invention for achieving the above object and the technical scheme taken is：
A kind of nut impact extrusion mould, the mould includes lower mold holder and top mold frame, and the upper surface of described lower mold holder is fixedly installed the
One backing plate, described the first backing plate upper surface arranges the second backing plate, is provided with die cavity in the second described backing plate, and described second
Backing plate upper surface arranges die, and described die, the first backing plate and the second backing plate coordinate fixation to set by arranging pressing plate and die sleeve
Put on lower mold holder, push rod is set on the first described backing plate, and one end of push rod is placed in die cavity, the die of described die
Hole is connected with described die cavity, and the upper end of described top mold frame is connected with die shank, and the lower end of described top mold frame arranges punch
Punch is set in fixed seat, described punch fixed seat, the 3rd backing plate is set between described punch and top mold frame, described is convex
Tapered sleeve is set between mould and punch fixed seat, and is fixed in punch fixed seat by arranging locking nut, described lower mold holder
Stripper is set and top mold frame between, and described stripper is just to arranging putting hole, and described placement on described die hole
Alignment pin is set in hole.
The present invention is disposal molding mould, and billot is put into into stripper positioning finger setting, and top mold frame is descending, and punch is opened
Contact billot begin simultaneously and the blanking to blank material, afterwards as part of the upper die continues traveling downwardly, punch are completed under the effect of die male
Continue to press on stock downwards, with die, push rod collective effect, complete the First Extrusion to stock and process, form semi-finished product, when
Top mold frame is continued traveling downwardly, and semi-finished product push-in type intracavity is carried out into the molding that secondary extrusion processes nut, and the mould is particularly suited for
Large batch of nut manufacture, and the nut quality produced is good, structural strength is high, good toughness.
Description of the drawings
Fig. 1 is the structural representation of the present invention.
