Abstract
The invention relates to a bar-shaped insulator support post molding die for a high-speed railway. The bar-shaped insulator support post molding die comprises an upper template and a lower template, wherein an upper punching head is arranged in the center of the upper template; a left vertical female die locking cylinder and a right vertical female die locking cylinder are arranged on both sides of the upper template respectively; a die seat is arranged on the lower template; a left female die and a right female die are arranged in the die seat, and are driven to move horizontally by a left side cylinder and a right side cylinder respectively; the end parts of piston rods of the left female die locking cylinder and the right female die locking cylinder have conical or wedged structures; and the outer side faces of the left female die and the right female die are provided with conical or wedged structures which are matched with the piston rods of the left female die locking cylinder and the right female die locking cylinder respectively. After the left side cylinder and the right side cylinder are used for driving die assembly of a left die kernel and a right die kernel, and the left female die locking cylinder, the right female die locking cylinder and the upper punching head descend quickly, the piston rods of the two female die locking cylinders are embedded into gaps between the left and right female dies and the die seat, and the piston rods are matched with the conical or wedged structures of the left and right female dies to drive the left and right die kernels to be locked, so that one-step molding of a small compression joint part is realized, the molding efficiency is improved, turning is avoided, and materials are saved.
Description
Technical field
The utility model relates to a kind of mould, particularly a kind of used for high-speed railway rod insulator pillar mould.
Background technology
Used for high-speed railway rod insulator pillar is used for the applied to high-speed railway touching net bracket to be supported; As shown in Figure 1, it is made up of with little pressure contact portion 15 big pressure contact portion 14, and big pressure contact portion 14 is that revolving body is tubular; And little pressure contact portion 15 is that non-revolved body is tubular, and the outer surface of little pressure contact portion middle part caves inward.
The mode of producing this kind used for high-speed railway rod insulator pillar at present has two kinds: a kind of is the method that adopts casting; 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; There is bigger potential safety hazard, and scraps more.
Can also adopt the method for forging, because shape and mould, after general used for high-speed railway rod insulator props up post mold and need forge big pressure contact portion earlier; Forge the blank structure of little pressure contact portion again, the semi-finished product that forge also need carry out machine work, can't one-shot forming; Prolonged machining period; And materials are many, and production cost is high, does not possess the market competitiveness.
The utility model content
The technical problem that the utility model will solve provides a kind of efficient height, used for high-speed railway rod insulator pillar mould that cost is low made.
For solving the problems of the technologies described above; The technical scheme of the utility model is: a kind of used for high-speed railway rod insulator pillar mould; Comprise cope match-plate pattern and lower bolster; Its innovative point is: said 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; On the said lower bolster die holder is installed, 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 are fixed with left and right die in the left and right die respectively, at the die holder center lower punch are installed also; The piston rod end of said left and right die locking cylinder is taper or wedge structure, and the lateral surface of said left and right die is provided with taper or the wedge structure that cooperates with left and right die locking cylinder piston rod.
Further, ejector beam is installed in the said lower punch, this ejector beam is driven by liftout tank.
The advantage of the utility model is: 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 descending fast, 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; Realize the one-shot forming of little pressure contact portion; Improve shaping efficiency, avoided Vehicle Processing, practiced thrift material.

Embodiment
As shown in Figure 2, comprise cope match-plate pattern 1, upper punch 2, left die locking cylinder 3, right die locking cylinder 4, lower bolster 5, die holder 6, left die 7, right die 8, left side cylinder 9, right side cylinder 10,
Above-mentioned cope match-plate pattern 1 center is equipped with upper punch 2, and both sides are separately installed with vertical left die locking cylinder 3 and right die locking cylinder 4, and the piston rod end of this two dies locking cylinder 3,4 is taper or wedge structure.
Die holder 6 is installed on the lower bolster 5; Be provided with left die 7, right die 8 in the die holder 6; Left side cylinder 9 and right side cylinder 10 are installed on the outside die holder 6 of left side die 7 and right die 8, and the cylinder body of left side cylinder 9, right side cylinder 10 is connected fixing with die holder 6, and piston rod is connected with right die 8 respectively at left die 7.
Be connected with left die 11 and right die 12 through bolt respectively in left side die 7 and the right die 8; This left side die 11 cooperates the appearance profile that constitutes used for high-speed railway rod insulator pillar with right die 12; At die holder 6 centers lower punch 13 is installed also, in this lower punch 13 ejector beam 17 that is connected with liftout tank is installed.Lower punch 13 and upper punch 2 are respectively the big pressure contact portion and the little pressure contact portion cavity shape of used for high-speed railway rod insulator pillar.
The outer wall of left side die 7 and right die 8 is corresponding taper that cooperates with the piston rod end of die locking cylinder 3,4 or wedge structure.
The utility model used for high-speed railway rod insulator props up the concrete operation principle of post mold shown in Fig. 2-5:
The blank that forges big pressure contact portion 16 is placed on the lower punch 13; Left side cylinder 9 advances with right side cylinder 10, make left die 11 and right die 12 matched moulds, slide block drive the left die locking cylinder 3 on the cope match-plate pattern 1, right die locking cylinder 4 and upper punch 2 descending fast after; Make the piston rod of two die locking cylinders embed the gap between left and right die and the die holder; It is descending to transfer work speed then to, and the passive oil extraction pressurize of two die locking cylinders is by upper punch 2 extrusion blanks upper end; And promote left die 11,12 lockings of right die by the die locking cylinder, realize the one-shot forming of little pressure contact portion.During the demoulding, left die locking cylinder 3, right die locking cylinder 4 and upper punch 2 are up with cope match-plate pattern 1, and left die 11 is retreated and opened with left side cylinder 9, right side cylinder 10 with right die 12, and ejector beam 17 jack-up products are realized the demoulding.
