according to the invention, the cavity for forming the hexagonal screw 100 is formed by matching the upper forming die 5 with the lower forming die 4, so that die liquid can enter the cavity through the liquid inlet 52, and the hexagonal screw 100 is formed.
The hexagonal screw 100 forming mold relates to a method for detecting the hexagonal screw 100 in a specific forming process, which comprises the following steps:
step S1: the annular plate 3 is divided into a forming area 31 for forming the hexagonal screw 100, a detection area 32 for detecting the hexagonal screw 100, a waste removing area 33 for rejecting the unqualified hexagonal screw 100 and a qualified product blanking area 34 for rejecting the qualified hexagonal screw 100;
step S2: a power control device 6 for controlling the annular plate 3 to move up and down is arranged between the annular plate 3 and the forming bottom plate 1, the power control device 6 synchronously drives the forming lower die 4 to rotate, and a rotating ring 7 for controlling the annular plate 3 to synchronously rotate is rotationally arranged on the mounting main rod 11 so as to rotate the hexagon screws 100 formed in the forming area 31 to the detection area 32;
step S3: the hexagonal screw 100 in the detection area 32 is detected by the detection device 8 arranged in the detection area 32 and mounted on the top-sealing panel 12, and the hexagonal screw 100 in the detection area 32 is rotated to the reject removing area 33, if the hexagonal screw 100 is rejected, the blanking is performed in the area, otherwise, the hexagonal screw 100 is rotated to the qualified product blanking area 34 for blanking.
In the implementation process, firstly, the annular plate 3 is driven to move upwards by the power control device 6 so that the lower molding die 4 on the annular plate 3 is matched with the upper molding die 5 above the annular plate to form a cavity, and then die liquid enters the cavity through the liquid inlet hole 52 to be cooled to form the hexagonal screw 100;
secondly, after the hexagonal screw 100 is molded, the annular plate 3 is driven to move downwards again through the power control device 6 so that the molded hexagonal screw 100 is separated from the upper molding die 5, and then the rotating ring 7 is driven to rotate under the action of external driving so that the annular plate 3 synchronously rotates along with the rotating ring so that the hexagonal screw 100 rotates to the detection area 32;
then, the power control device 6 continuously drives the annular plate 3 to move upwards so that the hexagonal screw 100 can detect the torsional strength and the sliding thread of the thread section through the detection device 8 of the detection area 32, the hexagonal screw 100 is continuously formed in the forming area 31 at the moment, after cooling, the annular plate 3 is driven to move downwards through the power control device 6 again, meanwhile, the annular plate 3 is rotated so that the hexagonal screw 100 of the detection area 32 is rotated to the reject area 33, if the annular plate is rejected, the annular plate is directly rejected, if the annular plate is qualified, the hexagonal screw 100 of the forming area 31 is transported to the detection area 32 to enable the detection device 8 to detect the hexagonal screw 100 of the detection area 32, and the hexagonal screw 100 of the forming area is rotated to the reject area 34 for blanking after the next round.
The reject removal zone 33 and the reject blanking zone 34 of the present invention are both blanked by existing equipment or manually.
Referring to fig. 2, a plurality of longitudinally installed guide strips 71 are uniformly arranged on the outer side wall of the rotating ring 7 in the axial direction, the annular plate 3 slides along the axial direction of the main mounting rod 11, and guide openings 72 for sliding the guide strips 71 are formed on the inner side wall of the annular plate; the invention drives the rotating ring 7 to rotate through the existing drive (such as a motor), so that the rotating ring 7 drives the annular plate 3 to synchronously rotate through the cooperation of the guide strip 71 and the guide opening 72; second, the sliding fit of the guide strip 71 with the guide opening 72 can restrict the rotation of the annular plate 3 on the rotation ring 7 when the annular plate 3 needs to be moved longitudinally.
With continued reference to fig. 2, the power control device 6 includes a plurality of longitudinally arranged power-driven internal thread rings 61 uniformly circumferentially arranged at the bottom of the forming base plate 1, an execution extension screw 62 is connected at the upper end of the power-driven internal thread rings 61 in a threaded manner, a matching ring 63 coaxial with the execution extension screw 62 is rotationally arranged at the bottom of the annular plate 3, the upper end of the execution extension screw 62 is fixed on the matching ring 63, a power gear 64 is mounted at the bottom of the power-driven internal thread rings 61, and an external tooth ring 65 meshed with the power gear 64 is rotationally mounted at the forming base plate 1.
In the implementation process, under the driving of external driving (for example, the external gear 65 is driven by a motor to rotate by driving a gear meshed with the external gear 65 to realize the rotation of the external gear 65), the external gear 65 is meshed with the power gear 64 to drive the power-driven internal thread ring 61 to rotate, and the execution extension screw 62 cannot synchronously rotate along with the power-driven internal thread ring 61 due to the fact that the execution extension screw 62 is fixedly arranged on the matching ring 63, so that the execution extension screw 62 is ensured to be in threaded fit with the power-driven internal thread ring 61 to drive the execution extension screw 62 to move along the axial direction of the execution extension screw, and the annular plate 3 is driven to synchronously move by the matching ring 63.
