As shown in fig. 4, the first slide block assembly includes a first slide block 9, a first pressing strip 10 and a first oil cylinder 11, wherein the first pressing strip 10 is arranged at two sides of the first slide block 9 and fixed on the rear mold plate 7; the first oil cylinder 11 is connected to one end of the first sliding block 9 through a T-shaped first connecting block 12, and the first sliding block 9 slides between the first pressing strips 10 on two sides under the power drive of the first oil cylinder 11. One end of the first sliding block 9, which is far away from the first oil cylinder 11, is provided with a first sliding block core 13, and the first sliding block core 13 is used for forming the shape of the pipe orifice 2.

The second sliding block assembly comprises a second sliding block 14, a second pressing strip 15 and a second oil cylinder 16, the second pressing strip 15 is arranged on two sides of the second sliding block 14, the second oil cylinder 16 is connected to one end of the second sliding block 14 through a T-shaped second connecting block 17, and the second sliding block 14 slides between the second pressing strips 15 on two sides under the driving of the second oil cylinder 16. The end of the second slide 14 remote from the second cylinder 16 is provided with a second slide core 18, and the second slide core 18 is used for forming the shape of the transverse tube 3.

The first sliding block 9 and the second sliding block 14 are arranged on the rear template 7 in a sliding mode, and the first sliding block 9 and the second sliding block 14 extend into the front template 5 in a sliding mode and form a product cavity formed by the bent pipe 1 together with the front mold core 6 and the rear mold core 8. The first sliding block 9 and the second sliding block 14 horizontally slide into the rear template 7 from the same side edge of the rear template 7, the second sliding block 14 slides in along the direction perpendicular to the side edge, the sliding-in direction of the first sliding block 9 and the sliding-in direction of the second sliding block 14 form a certain angle, and the two sliding blocks are intersected in the sliding meeting process.

As shown in fig. 5 to 7, a cavity 19 is further disposed in the first slider 9, an opening is formed on one side of the cavity 19 away from the first slider core 13, and a guide hole 20 communicating the cavity 19 and the first slider core 13 is formed on one side of the first slider 9.

In order to prevent the two sliders with different sliding directions from colliding in a meeting position, a first groove 21 with an upward opening is formed in the bottom of the cavity 19 of the first slider 9, a rectangular anti-collision block 22 is embedded in the first groove 21, and the shape of the first groove 21 is matched with that of the anti-collision block 22.

As shown in fig. 8 and 9, a second groove 24 with a downward opening is formed on the outer side of the bottom of the second slider 14, the horizontal inclined direction of the first groove 21 is consistent with that of the second groove 24, the crash block 22 can slide along the second groove 24, and the first groove 21, the crash block 22 and the second groove 24 form a structure for preventing slider collision.

As shown in fig. 10, when the injection molded product is clamped, the first slide block 9 and the second slide block 14 need to be positioned in the front mold plate 5 and the rear mold plate 7, when the first slide block 9 and the second slide block 14 start to be positioned, the first slide block 9 slides along the first bead 10 in the direction of the rear mold plate 7, and the second slide block 14 slides along the second bead 15 in the direction of the rear mold plate 7. When the first slide block 9 is in a normal position, before one end of the second slide block 14 slides into the cavity 19 of the first slide block 9, the anti-collision block 22 is firstly inserted into the second groove 24 at the bottom of the second slide block 14, then the second slide block 14 continues to slide towards the first slide block 9, and then the second slide block core 18 passes through the guide hole 20 and enters the product cavity; when the first slide block 9 is in an abnormal position, the anti-collision block 22 cannot be normally inserted into the second groove 24, but collides with the second slide block 14, so that the second slide block 14 is prevented from further moving, the collision between the first slide block 9 and the second slide block 14 is avoided, and the slide block parts are protected.

One end of the first groove 21 extends to the opening of the cavity 19, the anti-collision block 22 is fixedly connected to the bottom of the first groove 21 through a screw 23, the length of the anti-collision block 22 needs to be larger than that of the first groove 21, and the anti-collision block 22 extends outwards along the first groove 21.
