Abstract
The invention discloses a mold for a flash-free double-direction bending elbow. The mold comprises a fixed mold composed of a pair of fixed half molds, wherein the lower parts of the pair of fixed half molds are movably hinged with a moving half mold respectively, the pair of moving half molds form a moving mold, and the end parts at one side of the pair of moving half molds are respectively connected with a rotation driving device. The invention firstly bends an extruded straight tube blank into a one-direction bending elbow by the synchronization action of the fixed mold and the moving mold, and then changes the direction of the elbow in the moving mold to form the double-direction bending elbow by the cooperation of two rotation driving cylinders. Therefore, the produced double-direction bending elbow has no flash, thereby greatly lowering the production cost.
Description
Technical field
The present invention relates to mould, refer more particularly to mold for double-direction bending elbow.
Background technology
As everyone knows, be used for the mould of production compound bending bend pipe (shape tube) at present, it is relatively simple for structure, is generally the fixed die that a pair is made up of a pair of fixed mold.With the compound bending bend pipe that this die production is come out, overlap has occupied considerable share, has not only caused the serious waste of material, but also needs manpower that these overlaps are handled, and has increased production cost greatly.
Summary of the invention
A technical problem to be solved by this invention is: a kind of mold for double-direction bending elbow that does not have overlap is provided.
For solving the problems of the technologies described above; The technical scheme that the present invention adopts is: mold for double-direction bending elbow; Comprise: the fixed die that a pair is made up of a pair of fixed mold; This bottom to fixed mold is movably hinged with a movable half module respectively, and this a pair of movable half module constitutes a secondary movable mold, and this side end to movable half module links to each other with a rotating driving device respectively.
Described rotating driving device comprises oil cylinder seat and is movably arranged on the rotation driving oil cylinder on the oil cylinder seat that one side end of described a pair of movable half module links to each other with the piston rod of a rotation driving oil cylinder respectively.
The end, the same side of described a pair of movable half module links to each other with the piston rod of a rotation driving oil cylinder respectively.
The invention has the beneficial effects as follows: the present invention at first curves a bend pipe on the direction through fixed die and movable mold synchronization action with the straight tube blank of extruding; And then work together and change the direction of the bend pipe in the movable mold through two rotation driving oil cylinder; The gases at high pressure that then pass through the nozzle ejection are with the bend pipe cooling forming in fixed die and the movable mold, thus formation compound bending bend pipe.The compound bending bend pipe of producing does not like this have overlap, greatly reduces production cost.

The specific embodiment
Below in conjunction with accompanying drawing, describe specific embodiments of the present invention in detail.
As shown in Figure 1; Mold for double-direction bending elbow of the present invention; Comprise: the fixed die that a pair is made up of a pair of fixed mold 3 and 4; This bottom to fixed mold 3 and 4 is movably hinged with a movable half module 5 and 6 respectively, and this a pair of movable half module 5 and 6 constitutes a secondary movable mold, and wherein: fixed mold 4 is fixedly installed on the bearing support 2 with movable half module 6; Fixed mold 3 is fixedly installed on the bearing support 1 with movable half module 5, and bearing support 1 can correspond to bearing support 2 through translation driving device (not drawing among the figure) and do parallel moving and accomplish matched moulds and the demoulding is moved---and translation driving device belongs to the common technology in this area; Described a pair of movable half module 5 and 6 end, the same side link to each other with 8 piston rod with rotation driving oil cylinder 7 with 10 through oil cylinder seat 9 respectively.
The course of work of the present invention is: at first through the translation driving device matched moulds, promptly respectively fixed mold 3 and movable half module 5 and fixed mold 4 and movable half module 6 are closed, the straight tube blank of extruding is curved a bend pipe on the direction; Then; Under rotation driving oil cylinder 7 and 8 effect, movable half module 5 rotates around its hinged place with fixed mold 3, and movable half module 6 rotates around the hinged place of itself and fixed mold 4; Make the direction that is in the bend pipe in the movable mold change; Then, the gases at high pressure through nozzle ejection are with the bend pipe cooling forming in fixed die and the movable mold, thus formation compound bending bend pipe.The compound bending bend pipe of producing does not like this have overlap, greatly reduces production cost.
