step three, the movable die 1 and the fixed die 2 are opened, in the process of opening the die, the contact pressure between the inclined guide post 6 and the guide post groove generates lateral component force, the second-stage slide block 4 is pushed to move along the second-stage slide block sliding groove 5 and gradually leaves away from the die cavity, in the process, the second-stage slide block 4 pulls the core-pulling slide block 15 to retreat from the die cavity along the core-pulling sliding groove 10 and gradually releases the core-pulling slide block from the product 16, meanwhile, the shovel base 12 moves along the outer die in the axial direction to leave the first-stage slide block 3, the locking on the first-stage slide block 3 is released, after the core-pulling slide block 15 completely retreats from the die cavity, the sensor is triggered, under the control of a PLC, a piston rod of the oil cylinder 9 retracts, the first-stage slide block 3 is pulled to carry the second-stage slide block 4 and the core-pulling slide block 15 to move along a slope 13 and leave away from the die cavity, and a protruding part at the end part of the first-stage slide block 3 also releases from the product 16;
and step four, starting the ejector pin air cylinder, moving the ejector pin and pushing the product 16 out of the cavity.
Example 2:
as shown in fig. 6 and 7, the top end of the inclined guide post 6 is provided with a conical tip, which is convenient for aligning the guide post groove. The secondary slide block 4 is of a hollow structure, a guide pillar support 17 is arranged inside the secondary slide block 4, the guide pillar support 17 and the secondary slide block 4 are fixed through screws, the inclined guide pillar 6 is rotatably connected to the guide pillar support 17, and the inclined guide pillar 6 is kept in axial positioning on the guide pillar support 17 through a self step structure and a shaft check ring. Four shifting teeth 18 are evenly distributed on the circumferential surface of the bottom end of the oblique guide post 6, and the adjacent shifting teeth 18 form an included angle of 90 degrees relative to the axis of the oblique guide post 6. The bottom of the second-stage sliding block 4 is provided with a through groove 19, the bottom of the second-stage sliding block sliding groove 5 is provided with a shifting tooth stop block 20 and an inner groove bar stop block 23, the shifting tooth stop block 20 and the inner groove bar stop block 23 can enter the through groove 19, and the shifting tooth stop block 20 can contact and press the shifting tooth 18 before the second-stage sliding block 4 slides outwards to a limit position. An elastic stop pin 21 is further arranged inside the second-stage sliding block 4, the elastic stop pin 21 is connected to an inner groove strip 22 in a sliding mode and is connected with a spring, and the tail end of the spring is fixed to the inner groove strip 22. The tail end of the inner groove strip 22 is hinged to the inner wall of the second-stage sliding block 4, an expansion spring is arranged between the inner groove strip 22 and the inner wall of the second-stage sliding block 4, an inner groove strip guide inclined surface is arranged at one end, facing the second-stage sliding block 4, of the inner groove strip blocking block 23, and in the process that the second-stage sliding block 4 slides outwards, the inner groove strip 22 can be in contact with the inner groove strip guide inclined surface.
