Description of the embodiments

The following describes the embodiments of the present utility model in further detail with reference to the drawings.

From fig. 1 to fig. 5, it can be seen that a PE pipe elbow forming device, including fixed die plate 1 and movable die plate 2, fixed die plate 1 and movable die plate 2 structure are the same, the opposite direction is equipped with the die cavity 3 of a plurality of 90 degrees angles in the fixed die plate 1, the upper and lower both sides of die cavity 3 are along horizontal plane symmetrical arrangement, the intracavity is provided with core 4 in the die cavity 3, core 4 tip is equipped with 45 curved 5, form the inner core of PE pipe after two core 4 butt joints, a plurality of core 4 rear ends that are located same one side are fixed on same fixed plate 6, the pneumatic cylinder 7 that is located on the fixed die plate 1 is connected to fixed plate 6, the pneumatic cylinder 7 drives a plurality of cores 4 synchronous motion, the die cavity 3 of fixed die plate 1 is equipped with the mouth 8 of moulding plastics.

In the specific use of the present utility model,

when the PE pipe elbow production device is used, the fixed die plate 1 is fixed, the movable die plate 2 is arranged on a line capable of being matched with the fixed die plate 1 in a sliding mode, when the PE pipe elbow is produced, the fixed die plate 1 and the movable die plate 2 are matched, two cores 4 are close inwards to realize butt joint to form an inner core, then injection molding is carried out from an injection molding opening 8 into a die cavity 3, after injection molding is finished, the movable die plate 2 is separated, the cores 4 move outwards, the molded PE pipe elbow can fall, and therefore the next injection molding process is finished.

The inside of the movable platen 2 and the fixed platen 1 is provided with a cooling device outside the cavity 3, which is a means of conventional technology in the art and will not be described in detail here.

The two axes of the die cavity 3 form an angle of 45 degrees with the horizontal plane, the two axes are positioned in the same vertical plane, and the die cavity 3 is obliquely arranged, so that the two adjacent die cavities 3 can be mutually close to each other, the empty space is reduced, the die utilization rate is improved, the die volume is reduced, more die cavities 3 are arranged in the space with the same size, and the forming efficiency of unit space is improved.
