[0023] The utility model discloses a rapid injection mold for an anti-counterfeiting packaging barrel. After the anti-counterfeiting packaging barrel 9 is injection molded, the cooling water channel starts to circulate. The cooling water is input from the lower water inlet 32, and the cooling water flows through the lower water inlet water channel 34, the lower annular water channel 36, and the lower water outlet water channel 35. Finally, it flows out from the lower water outlet 33 to cool the movable mold plate 6, the movable mold insert 7, and the top insert 8, so that the inner wall of the anti-counterfeiting packaging barrel 9 can be quickly cooled. At the same time, the upper water inlet water channel 41 of the upper composite plate 1 inputs cooling water, and the cooling water flows through the upper annular water channel 43 of the fixed mold insert 4 from the upper The water outlet water channel 42 flows out to cool the upper composite plate 1 and the fixed mold insert 18, so that the bottom of the anti-counterfeiting packaging barrel 9 can be quickly cooled, and the cooling water is input into the mouth ring water inlet 24, and the cooling water is output from the mouth ring water outlet 25 through the mouth ring annular water channel 23, so that the flange 10 of the anti-counterfeiting packaging barrel 9 can be quickly cooled. After the anti-counterfeiting packaging barrel 9 is cooled and finalized, the lower composite plate 2 drives the mold foot 5, the ejection device, the movable mold plate 6, the movable mold insert 7, the top insert 8, the center top block 15, the ejector rod 16, the top ring 17, the side core-pulling slider 18, the mouth ring insert 22 and the anti-counterfeiting packaging barrel 9. The packaging barrel 9 moves downward together, while the upper composite plate 1, the fixed mold plate 3 and the fixed mold insert 4, and the locking module 20 remain stationary. The mold is opened from the fixed mold plate 3 and the movable mold plate 6, and the locking module 20 withdraws from the top ring 17. At this time, the high-pressure gas is blown in through the air inlet 51 by the high-pressure air pump. Under the action of the high-pressure gas, the blowing valve 53 opens upward, and the gas enters the gap between the anti-counterfeiting packaging barrel 9 and the top insert 8, thereby eliminating the negative pressure generated between the two, reducing the clamping force of the anti-counterfeiting packaging barrel on the top insert 8 and the movable mold insert 7, and at the same time, the power (dynamic The force may be a pneumatic cylinder or an oil cylinder) drives the side core-pulling slider 18 to pull out the handle mounting hole 12 outward, and the oil cylinder 31 drives the push rod 16 to move upward, and the push rod 16 pushes the central top block 15 and the upper top ring 17 and the lower top ring 21 to move upward together, and the central top block 15 pushes the anti-counterfeiting packaging barrel 9 upward to escape from the movable mold insert 7 and the top insert 8, and the upper top ring 17 and the lower top ring 21 push the flange 10 at the mouth of the anti-counterfeiting packaging barrel 9 to move upward, and at the same time, the slot 11 on the barrel mouth of the anti-counterfeiting packaging barrel escapes from the top ring 17 upward, so that the anti-counterfeiting packaging barrel 9 is demoulded.The present invention provides a rapid injection mold for an anti-counterfeiting packaging barrel. First, when the mold is closed for injection molding, a locking module 20 is set on one side of the fixed mold plate 3 to lock the side core-pulling slider 18. The locking is reliable and the stability of the mold is guaranteed. Second, after the mold is injection-molded, cooling water is input through the upper water inlet waterway 41 and the lower water inlet 32 to cool the mold, so that the anti-counterfeiting packaging barrel 9 can be quickly cooled and shaped, with good cooling effect and reduced cooling time, thereby improving the production efficiency of the mold. Third, when the mold is opened, the side core-pulling slider 18 is withdrawn through the locking module 20, and the side core-pulling slider 18 is driven by power to move outward to pull the core, and then the ejector rod 16 and the center ejector block 15 are combined with high-pressure gas to assist in demolding, so as to eliminate the negative pressure between the anti-counterfeiting packaging barrel 9 and the top insert 8 and the movable mold insert 7, so that the anti-counterfeiting packaging barrel 9 can be ejected and demolded more smoothly, demolding is easy, product deformation is avoided, product quality is guaranteed, and the product yield rate is improved.
