Abstract
The utility model relates to a bent pipe injection die. A primary cavity is surrounded by a moving die plate and a fixed die plate. The moving die plate and the fixed die plate are arranged on both sides of the primary cavity. The moving die plate is respectively provided with a first sliding block and a second sliding block. The fixed die plate is provided with a first slanted guide pillar and a second slanted guide pillar. The first slanted guide pillar passes through the fixed die plate, the first sliding block and the moving die plate sequentially. The second slanted guide pillar passes through the fixed die plate, the second sliding block and the moving die plate sequentially. The first sliding block is provided with a first straight core. The second sliding block is provided with a second straight core. The bent pipe injection die also comprises a bending core, a rotating guide block and a driving mechanism, wherein the bending core comprises an arc bending section and an inserting section; the inserting section of the bending core is inserted into the second straight core; the rotating guide block is positioned in an arc guide rail; the driving mechanism is used for driving the rotating guide block to slide in the arc guide rail; and the driving mechanism and the inserting section of the bending core are both connected with the rotating guide block. The utility model provides the bent pipe injection die which can carry out both straight and arc core pulling and makes the formation of a pipe joint both ends of which are straight and the middle of which bends in an arc mode possible.
Description
(1) technical field
The utility model relates to a kind of bend pipe injection mold.
(2) background technology
Use the very universal world today at plastic conduit, mould all adopts common core-pulling mechanism can realize the demoulding generally speaking, but the pipe joint of the straight medial arc bending in two as described in Figure 3 has the core-pulling mechanism of straight line and camber line dual-action concurrently when loosing core, state's inner mold has straight line and the camber line difficulty of loosing core concurrently in pipe joint field design, so far still technological gap.
(3) summary of the invention
In view of also there not being at present a kind of bend pipe injection mold that straight line and camber line are loosed core that has concurrently, the utility model provides a kind of bend pipe injection mold that straight line and camber line are loosed core that has concurrently.

Be fixed with the first straight core on described first slide block, be fixed with the second straight core on described second slide block; Also comprise curved core, this curved core comprises the arc-shaped bend section and inserts section that the insertion section of described curved core penetrates the described second straight core slidably; The arc-shaped bend section of described curved core is positioned between the described first straight core and the second straight core, the arc-shaped bend section of described curved core, the first straight core and the second straight core are positioned at described preliminary die cavity, and the arc-shaped bend section of described solid plate, the first straight core, curved core, the second straight core, moving platen surround the moulding die cavity;
Also comprise the rotation guide block, described rotation guide block be positioned at one with the identical arc-shaped guide rail of crooked radian of the arc-shaped bend section of curved core; Comprise also being used to drive the driving mechanism that described rotation guide block slides that in described arc-shaped guide rail the described rotation guide block of the insertion Duan Junyu of described driving mechanism and described curved core connects.
Further, described driving mechanism is a hydraulic jack.
In the die sinking process, at first, along with separating of mould moving platen and solid plate, product is pulled to moving platen, first Angle Pin, second Angle Pin dependence mould opening force band first slide block and second slide block carry out straight line and loose core, separate fully until active and inactive mold, the first straight core, the second straight core detach from the bend pipe plastic fully, at this moment, the driving mechanism action, the rotation guide block is rotated by predetermined arc in arc-shaped guide rail, and curved core is followed to be synchronized with the movement and carried out arc core-pulling, extracts out from the bend pipe plastic fully until the arc-shaped bend section of curved core.
The beneficial effects of the utility model are: a kind of bend pipe injection mold that straight line and camber line are loosed core that has concurrently is provided, makes the pipe joint of the straight medial arc bending in moulding two become possibility.
