The mode of producing the double fastener hoop at present has two kinds: a kind of is the method that adopts casting, and it exists shortcoming to be: interior tissue is loose, and defectives such as shrinkage cavity, crackle are arranged, and can't meet the quality requirement, and has bigger potential safety hazard, and scraps more.
Can also adopt the method for forging, for example number of patent application 201110203387.7 discloses a kind of used for high-speed railway rod insulator pillar mould, it comprises cope match-plate pattern and lower bolster, the cope match-plate pattern center is equipped with upper punch, and both sides are separately installed with vertical left die locking cylinder and right die locking cylinder; Die holder is installed on the lower bolster, is provided with left die, right die in the die holder, this left side die and right die are driven by left side cylinder and right side cylinder respectively and move horizontally, and left and right die is fixedly arranged respectively in the left and right die, at the die holder center lower punch are installed also; The piston rod end of described left and right die locking cylinder is taper or wedge structure, and the lateral surface of left and right die is provided with taper or the wedge structure that cooperates with left and right die locking cylinder piston rod.
During moulding, promote left and right die matched moulds by the left and right sides cylinder, after left and right die locking cylinder on the slide block driving cope match-plate pattern and upper punch are quick descending, make the piston rod of two die locking cylinders embed the gap between left and right die and the die holder, utilize the piston rod of die locking cylinder to cooperate the left die of promotion, the locking of right die with left and right die taper or wedge structure, the one-shot forming of realization has improved shaping efficiency, avoid Vehicle Processing, saved material.But still there is certain problem: left and right side cylinder matched moulds need be installed simultaneously, left and right die locking cylinder, oil cylinder quantity is many, complex structure, volume is big, manufacturing cost height, big energy-consuming during use.
Summary of the invention
The technical problems to be solved in the utility model provide a kind of simple in structure, working (machining) efficiency is high and the high-speed railway insulator that is convenient in demoulding with forging and molding mould of double fastener hoop.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of high-speed railway insulator is with forging and molding mould of double fastener hoop, comprise upper die component and following membrane module, its innovative point is: upper die component comprises upper plate, cope match-plate pattern, punch, by cope match-plate pattern punch is installed on the lower surface of upper plate; Following membrane module comprises lower shoe, die holder, framed, core rod, internal mold push rod, push rod, jacking block, die holder is fixed on the lower shoe, and the die holder center has places framed inner chamber, left and right two madial walls of die holder are inclined-plane A, all have the T shape gathering sill that extends along inclined-plane A direction at A center, inclined-plane; Framed, comprise identical left framed and right framed of structure, framed and die holder adopt wedge structure to cooperate: the left and right framed arranged outside inclined-plane B identical with the die holder madial wall inclined-plane A gradient, inclined-plane B is provided with T shape guide pad, T shape guide pad extends along inclined-plane B direction, and T shape guide pad embeds in the T shape gathering sill and constitutes the guiding mechanism with gradient; Core rod comprises left and right core rod, left and right core rod respectively by bolt be installed in a left side framed and right framed on, left and right core rod can constitute the die cavity of double fastener hoop behind left and right framed matched moulds, and leaves a plug patchhole below die cavity; The internal mold push rod is fixed on the lower shoe center, also is provided with left and right push rod in lower shoe, and left and right push rod is installed on the jacking block, and left and right push rod lays respectively at left and right framed below.
Advantage of the present utility model is: during compacting, double fastener hoop blank is in heating is placed on core rod, and upper plate is descending, cooperates a compression moulding by punch with left core rod, right core rod, internal mold push rod; During the demoulding, jacking block is with the two push rods jack-up that makes progress, and core rod moves with on framed; When the double fastener hoop in the core rod is thrown off the internal mold push rod, under the effect of guiding mechanism, move the limit on the framed limit and open to both sides, can realize that the demoulding takes off the double fastener hoop.Thereby realize a compression moulding smoothly, compacting efficient height, and be convenient in demoulding, utilize guiding mechanism locked mode and the demoulding, significantly reduced oil cylinder quantity, cut down the consumption of energy.
