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

A kind of nut impact extrusion mould
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.
Specific embodiment
The specific embodiment of the present invention is made a detailed explanation below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of nut impact extrusion mould, the mould includes lower mold holder 1 and top mold frame 16, described lower mold holder 1 Upper surface be fixedly installed the first backing plate 3, the described upper surface of the first backing plate 3 arranges the second backing plate 4, the second described backing plate 4 Inside it is provided with die cavity, the described upper surface of the second backing plate 4 arranges die 6, described die 6, the first backing plate 3 and the second backing plate 4 It is fixedly installed on lower mold holder 1 by arranging pressing plate 8 and the cooperation of die sleeve 5, push rod 2, and push rod is set on the first described backing plate 3 2 one end is placed in die cavity, and the die hole of described die 6 is connected with described die cavity, the upper end of described top mold frame 16 It is connected with die shank 17, the lower end of described top mold frame 16 arranges punch fixed seat 14, arranges convex in described punch fixed seat 14 3rd backing plate 15 is set between mould 13, described punch 13 and top mold frame 16, between described punch 13 and punch fixed seat 14 Tapered sleeve 12 is set, and is fixed in punch fixed seat 14 by arranging locking nut 11, described lower mold holder 1 and top mold frame 16 it Between stripper 10 is set, described stripper 10 just sets to arranging on described die hole in putting hole, and described putting hole Put alignment pin.
