A cooling water cavity 203 and an extrusion water cavity 204 are provided between the upper outer mold 103 and the upper inner mold 201. An inlet pipeline is connected above the cooling water cavity 203, and an outlet pipeline is connected below the cooling water cavity 203. A top block 206 is slidably connected inside the upper inner mold 201, and a closing valve 004 is provided inside the top block 206. The closing valve 004 is used to seal the material inlet of the upper inner mold 201 to prevent the product of the packaging box from adhering to the injection molding material; A sealing ring 205 is arranged between the upper inner mold 201 and the upper outer mold 103 for sealing the internal cooling water cavity 203 to prevent the leakage of cooling water. The outer end of the ejector block 206 penetrates through the upper outer mold 103 and extends to the outside of the upper outer mold 103. A side ear 207 is fixedly connected to the outer end of the ejector block 206. A first piston 208 is fixedly connected to the outside of the ejector block 206. The first piston 208 is located inside the extrusion water cavity 204. A spring is sleeved on the outside of the ejector block 206. The two ends of the spring are respectively in contact with the first piston 208 and the upper inner mold 201. Under the action of the spring, it is convenient to drive the ejector block 206 to reset.

[0021] The upper power group 003 is arranged inside the C-shaped bracket 101 and includes a fixed connecting rod 304. A second limiting rod 305 is fixedly connected to the inside of the fixed connecting rod 304. A feeding pipe 301 is arranged at the output end of the injection extruder 102. A fixed sleeve 303 is installed on the outside of the feeding pipe 301. The injection head 302 at the end of the feeding pipe 301 is adapted to the inner cavity of the ejector block 206. There are four fixed connecting rods 304, and the four fixed connecting rods 304 are distributed in a circular array around the feeding pipe 301. A movable block 306 is slidably connected to the outside of the second limiting rod 305. The fixed sleeve 303 is fixedly connected to the feeding pipe 301. The outside of the fixed sleeve 303 is inclined. An inclined block 307 adapted to the fixed sleeve 303 is arranged at one end of the movable block 306 close to the injection extruder 102. A pushing block 308 is arranged at the other end of the movable block 306; In the above structure, a protective cylinder 309 is fixedly connected to one side of the inside of the C-shaped bracket 101 close to the injection extruder 102. The protective cylinder 309 wraps the fixed connecting rod 304. A limiting groove 310 is opened on the inside of the protective cylinder 309. The side ear 207 is adapted to the pushing block 308 and is slidably connected to the limiting groove 310.

[0022] Before injection molding, the water inlet valve of the cooling water is in a closed state. When injection molding is required, the upper power group 003 is pushed towards the upper molding module 002, so that the injection head 302 enters the inside of the ejector block 206. At this time, the injection head 302 cooperates with the upper inner mold 201, and then injection molding is carried out. After injection molding is completed, the valve of the cooling water is opened, and then the injection head 302 is driven. The injection head 302 moves away from the ejector block 206. When cooling is completed, the water valve is closed. When the injection head 302 moves away from the closing valve 004, the closing valve 004 automatically closes to prevent adhesion. At this time, the water passing groove 405 inside the closing valve 004 is exposed; In order to further flexibly eject the material from the mold, when the fixed sleeve 303 on the outside of the injection head 302 contacts the tilting block 307, the movable block 306 is pushed to slide outward on the outside of the limiting rod 205, wherein the outer sleeve of the limiting rod 205 is provided with a spring for driving the movable block 306 to reset. When the movable block 306 slides outward, the pushing block 308 also slides outward, thereby squeezing the side ear 207, driving the side ear 207 to drive the ejection block 206 to slide inward, and the side ear 207 slides inside the limiting groove 310, which is convenient for limiting the side ear 207. At the same time, the protective tube 3 09 can protect the parts. When the ejector block 206 slides inward, the first piston 208 squeezes the cooling water inside the extrusion water chamber 204, so that the cooling water enters the inside of the movable groove 401 through the channel, and under high pressure, enters the inside of the injection cavity through the water groove 405. At this time, the ejector block 206 also slides into the injection cavity. At the same time, the hydraulic cylinder 104 drives the lower outer mold 105 away from the upper outer mold 103. The product is discharged under the push of the ejector block 206. Combined with the push of water, flexible demoulding can be performed, and the cooling water is in direct contact with the product, which speeds up the cooling time.

[0023] Among them, the closing valve 004 includes a movable groove 401, which is provided with four movable grooves 401 and is distributed in an annular manner inside the ejection block 206. The movable groove 401 is internally slidably connected with a closing block 402, which is provided with four closing blocks 402 and is tilted on the side close to the first piston 208. The interior of the ejection block 206 is located in the movable groove 401 where a limiting cavity is provided. Both sides of the closing block 402 are fixedly connected to a limiting strip 403, which is adapted to the limiting cavity. A first elastic member 404 is provided between the limiting strip 403 and the inner wall of the movable groove 401. The four closing blocks 402 cooperate with each other, and a channel is provided inside the ejection block 206. The cooling water cavity 203 is connected to the movable groove 401 through the channel.

[0024] When the closing block 402 is squeezed, the closing block 402 contracts toward the inside of the movable groove 401, squeezing the first elastic member 404, and the limiting strip 403 slides in the limiting cavity inside the movable groove 401 to facilitate limiting. At this time, the water groove 405 is blocked, and the movable groove 401 is blocked by the injection head 302, so the cooling water inside will not leak out. The setting of the closing valve 004 can not only prevent adhesion but also allow cooling water to push the flexible output part, greatly improving the cooling effect and facilitating the protection of the product.

[0025] Furthermore, the lower molding module 005 includes a lower inner mold 501, which is mounted inside the lower outer mold 105 by screws. A water channel is provided inside the lower inner mold 501, and the water channel includes a water inlet tank 504 and a water storage tank 505. A fixing column 510 is slidably connected to the interior of the lower outer mold 105 and the lower inner mold 501. The end of the fixing column 510 is fixedly connected to the second piston 511. The end of the second piston 511 is fixedly connected to the first rack 512. The side of the first rack 512 is meshedly connected to a gear 513 rotatably connected to the lower inner mold 501. The side of the gear 513 is meshedly connected to a second rack 514. The end of the second rack 514 is fixedly connected to a block 515. When cooling the lower inner mold 501, cooling water is injected into the water inlet tank 504 through the water inlet pipe 503, and is transmitted from the water inlet tank 504 to the inside of each cooling pipe 506, and then input into the inside of the merging pipe 508 through the return pipe 507, thereby completing the cooling of the material. The cooling water is output from the inside of the merging pipe 508 through the water outlet pipe 509 to complete the cooling cycle.

[0026] The inner side of the lower inner mold 501 is provided with a groove 502 that matches the protrusion 202. The water channel provided inside the lower inner mold 501 also includes a water inlet pipe 503, which is connected to the water inlet tank 504. The end of the water inlet tank 504 is connected to multiple cooling pipes 506. The cooling pipes 506 are connected to the merging pipe 508 through the return pipe 507. The bottom of the merging pipe 508 is connected to the water outlet pipe 509. Among them, the blocking block 515 and the second piston 511 are both in contact with the inner wall of the water inlet tank 504. The blocking block 515 is connected to the inner wall of the water inlet tank 504. 15 are fixedly connected to both sides of the support bar 516, the interior of the lower inner mold 501 is provided with a slide groove 517, and the support bar 516 is adapted to the slide groove 517; wherein, the interior of the lower inner mold 501 is provided with a slot, the interior of the lower outer mold 105 is provided with a connecting groove adapted to the slot, the ejector pin 601 passes through the slot and the connecting groove, and the bottom of the lower outer mold 105 is connected with an inlet pipe 701 and an outlet pipe 702, and the inlet pipe 701 and the outlet pipe 702 are respectively connected to the water inlet pipe 503 and the water outlet pipe 509.

[0027] After injection molding is completed, cooling is carried out. After cooling ends, the water inlet valve is closed, and then the hydraulic cylinder 104 is started. The hydraulic cylinder 104 drives the lower outer mold 105 to retract and move away from the upper molding module 002. At this time, the fixed column 510 remains stationary, and the lower inner mold 501 drives the gear 513 and the plug 515 to move. The gear 513 rotates under the action of the first rack 512. The rotation of the gear 513 will drive the second rack 514 to move relative to the gear 513. The second rack 514 drives the plug 515 and the support bar 516 to slide inside the lower inner mold 501. At this time, the support bar 516 slides inside the chute 517, which is convenient for positioning. Among them, the plug 515 will gradually move away from the cooling pipe 506, making the end of the cooling pipe 506 facing the plug 515 exposed. At this time, the second piston 511 gradually slides inside the water inlet groove 504, and can squeeze out the cooling water in the water inlet groove 504, making the cooling water contact the product, which can not only cool the product, but also eject the product; In a further optimization of the above embodiment, the ejector 006 includes four ejector pins 601. The four ejector pins 601 are distributed in a circular array around the lower inner mold 501. The ejector pins 601 penetrate through the inside of the lower inner mold 501 and the lower outer mold 105. One end of the ejector pin 601 close to the lower inner mold 501 is fixedly connected with an ejector block 602. A stopper 604 is fixedly connected to the outside of the ejector pin 601. A second elastic member 603 is sleeved on the outside of the ejector pin 601. The two ends of the second elastic member 603 are respectively in contact with the stopper 604 and the lower outer mold 105.

[0028] When the ejector pin 601 contacts the C-shaped bracket 101, the ejector pin 601 remains stationary, and the lower outer mold 105 moves, which can make the ejector pin 601 extend out of the slot and eject the material, thus completing the discharge design of the packaging box. The second elastic member 603 can make the ejector pin 601 automatically reset.

[0029] Among them, the cooling water inside the upper molding module 002 and the lower molding module 005 is controlled by an external water pump, and the water can be circulated and cooled, and water can be automatically replenished. For the water that has flowed out, it can be recycled and filtered for reuse. This is the prior art and will not be elaborated here.
