s12, a piston rod of the stamping driving cylinder (521) continuously extends out to push the insert (200) in the insert placing hole (831) to move downwards in the insert placing hole (831), and due to the fact that an opening is formed in the side wall of the annular insert (200) and the aperture of the lower end portion of the insert placing hole (831) is smaller than the diameter of the insert (200) in a normal state, when the insert (200) moves to the lower end portion of the insert placing hole (831), the insert (200) is extruded, the opening distance of the insert (200) is reduced, and the diameter of the insert (200) is smaller than the aperture of the lower end portion of the insert placing hole (831);
s13, with the continuous extension of a piston rod of the stamping driving cylinder (521), the insert (200) is pushed out of the insert placing hole (831), and the lower end part of the insert (200) firstly enters the insert placing hole at the edge of the injection molding piece (100);
s14, when the insert (200) is pressed and mounted by an insert pressing rod (522), and the insert (200) is in contact with a product positioning insert (4752), the insert (200) and the product positioning insert (4752) synchronously move downwards, a positioning insert spring (4753) is compressed, when the product positioning insert (4752) touches a return signal switch (4754), the insert (200) is mounted in place, a gate punching driving cylinder (531) and a punching driving cylinder (521) are reset for next mounting, and the insert (200) is pressed and mounted at a first position of an injection molding part (100);
s15, starting a motor (41), and driving a driving transmission gear (44) and a driven transmission gear (45) through a transmission belt (43) to enable a cam divider (46) to work to drive a lower rotary disc (471) and an upper rotary disc (472) to rotate for 120 degrees;
s16, repeating the steps S4-S14, and press-fitting the insert (200) at the second position of the injection molding piece (100);
s17, starting a motor (41), and driving a driving transmission gear (44) and a driven transmission gear (45) through a transmission belt (43) to enable a cam divider (46) to work to drive a lower rotary disc (471) and an upper rotary disc (472) to rotate for 120 degrees;
s18, repeating the steps S4-S14, and pressing the insert (200) at the third position of the injection molding piece (100);
s19, driving a horizontal supporting plate (34) to move along two linear guide rails (33) which are arranged in parallel by a horizontal driving cylinder (32), so that a product rotating platform (4) moves out of the product insert press-fitting device (5), taking down the injection molding (100) provided with the three inserts (200) through a manual or mechanical arm, putting two injection molding (100) to be assembled again, and repeating the press-fitting.
