The outer side wall of the lower die 2 is fixedly provided with a hydraulic motor 6, the output end of the hydraulic motor 6 faces the lower die 2 and is coaxially fixedly provided with a transmission shaft 7, the transmission shaft 7 is coaxially fixedly provided with a first gear 51, the first gear 51 is meshed with an intermediate gear 53, and the first gear 51 and the second gear 52 are meshed with different tooth bodies of the intermediate gear 53. When the hydraulic motor 6 is operated, the hydraulic motor 6 drives the first gear 51 to rotate through the transmission shaft 7, the first gear 51 drives the second gear 52 to rotate through the meshing action of the intermediate gear 53, and the second gear 52 drives the outer core 42 to rotate so as to unscrew the thread forming part 421 from the product. The intermediate gear 53 is used to adjust the transmission ratio of the first gear 51 and the second gear 52 so that the outer core 42 rotates at an appropriate speed, and damage to the screw hole 10 can be prevented to some extent.
As shown in fig. 3 and 4, the position of the wheel axle 531 in the core block 4 is adjustable, and a locking mechanism 8 for locking the position of the wheel axle 531 is provided in the core block 4. The locking mechanism 8 comprises locking blocks 81 sleeved at two ends of the wheel axle 531, the wheel axle 531 can rotate in the locking blocks 81, and two ends of the locking blocks 81 in the horizontal direction are sharp. A plurality of clamping grooves 82 are formed in the core pulling block 4 along the connecting line direction of the first gear 51 and the second gear 52, the clamping grooves 82 are continuously arranged into a zigzag shape, and the zigzag groove walls are used for embedding sharp ends of the locking blocks 81.

As shown in fig. 5 and 6, the drive shaft 7 includes a first shaft 71 fixedly connected to the hydraulic motor 6, and a second shaft 72 fixedly connected to the first gear 51, the first shaft 71 and the second shaft 72 being separable from each other. Two protruding blocks 711 are fixed on the end surface of the first shaft 71 facing the second shaft 72, and the two protruding blocks 711 are symmetrically distributed about the axis of the first shaft 71; the end face of the second shaft 72 facing the first shaft 71 is provided with two grooves 721, two protruding blocks 711 are respectively inserted into the two grooves 721, and a rotation gap 74 is reserved between the protruding blocks 711 and the side wall of the grooves 721. The elastic member 73 is provided in the rotation gap 74, the elastic member 73 is formed by bending a metal sheet, the elastic member 73 includes a first plate 731 fixed to one side wall of the recess 721, an intermediate plate 732 connected to an end of the first plate 731, and a second plate 733 connected to an end of the intermediate plate 732 facing away from the first plate 731, and a cross-sectional shape of the elastic member 73 along a radial direction of the transmission shaft 7 is Z-shaped. When the first shaft 71 drives the core block 4 to move in the core-pulling direction, the elastic member 73 is compressed.
When the screw core pulling process starts, the hydraulic motor 6 drives the first shaft 71 to rotate, the first shaft 71 presses the elastic member 73 through the protrusion 711, the elastic member 73 is gradually flattened, and the reaction force of the elastic member 73 acts on the second shaft 72 through the groove wall of the groove 721, so that the torque of the second shaft 72 is gradually increased. When the elastic member 73 is compressed to a certain thickness, the torque of the second shaft 72 reaches a critical value for driving the outer core 42 to rotate, and the second shaft 72 rotates to drive the outer core 42 to rotate for performing the thread pulling process. Because the torque driving the outer core 42 to rotate is gradually increased, the adhesion force between the thread forming part 421 and the product at the beginning of core pulling can be gradually overcome, and the probability of damage of the product due to sudden overlarge stress is reduced.
As shown in fig. 2 and 3, the driving mechanism 3 includes a worm 31 coaxially fixed to the second shaft 72, and a tooth portion 32 fixed to the bottom surface of the core block 4, the longitudinal direction of the tooth portion 32 is the same as the sliding direction of the core block 4, and the worm 31 is engaged with the tooth portion 32. The gear ratio of the worm 31 and the tooth 32 is preset as: the worm 31 drives the teeth 32 to move at the same rate as the outer core 42 is rotated out of the product. In this way, when the outer core 42 moves synchronously in a direction away from the product during the process of unscrewing the screw forming portion 421 from the product, the axial force of the screw forming portion 421 on the screw hole 10 is small, and the screw hole 10 of the product is not easily damaged; on the other hand, the hydraulic motor 6 drives the core-pulling block 4 to move while driving the outer core 42 to rotate, so that the input cost of a driving source is reduced.
The working process of the die is as follows: after the product is cooled and molded, the upper die 1 and the lower die 2 are separated, and then a core pulling process is carried out. When the hydraulic motor 6 simultaneously drives the outer core 42 to rotate and the core block 4 to move, the screw forming portion 421 is screwed out of the screw hole 10, and the inner core 41 is pulled out of the through hole 101. Since the inner core 41 does not rotate, the inner core 41 is not likely to scratch the wall of the via hole 101 during the extraction process.
The foregoing is merely exemplary embodiments of the present invention and is not intended to limit the scope of the invention, which is defined by the appended claims.
