Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0058] like Figures 1 to 13 As shown, a molding processing device and method based on an EPP material packaging box includes the following embodiments:

[0059] Embodiment 1: Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, it includes an operating table 1, an injection molding machine 2 is arranged on the top of the operating table 1, and a moving module 201 for driving the injection molding machine 2 to move during injection molding is arranged at the bottom of the injection molding machine 2. The moving module 201 adopts an existing hydraulic cylinder or an electric push rod to complete the smooth fitting of the injection head arranged on the injection molding machine 2 with the injection port of the mold, and also includes:

[0060] A support plate 301 is fixedly connected to the top of the operating table 1. A fixed mold 3 for injection molding is fixedly connected to the support plate 301 on the side away from the injection molding machine 2. Two movable molds 4 for adapting to the fixed mold 3 are arranged on one side of the fixed mold 3. The two movable molds 4 are fixed by a support plate and are arranged horizontally.

[0061] A switching component is arranged at the bottom of one of the movable molds 4 and is used to drive the two movable molds 4 to switch left and right and alternately combine with the fixed mold 3;

[0062] Two groups of spraying components, the two groups of spraying components are respectively arranged on both sides of the support plate 301, when the switching component switches the two movable molds 4, the spraying components spray the release agent on the inner part of the movable mold 4;

[0063] The spraying assembly includes a fixed spraying structure and an adjustable spraying structure, which are used to spray the release agent on the molding interior of the movable mold 4. The fixed spraying structure realizes large-scale spraying, and the adjustable spraying structure specifies spraying at a special position.

[0064] During specific implementation, one of the movable molds 4 is fitted with the fixed mold 3 through the switching component, and then the injection head of the injection molding machine 2 is fitted with the injection port of the fixed mold 3 through the mobile module 201, and then injection molding is performed; after the injection is cooled, the movable mold 4 is separated from the fixed mold 3 through the switching component, and the workpiece inside the movable mold 4 is taken out; then the other movable mold 4 is re-fitted with the fixed mold 3 through the switching component, and the other movable mold 4 is switched to the spraying component on the side of the fixed side plate 6, and the used movable mold 4 is sprayed with a release agent; the two movable molds 4 are alternately fitted with the fixed mold 3 for injection molding, thereby avoiding the waste of cooling time of the injection molded workpiece between the movable mold 4 and the fixed mold 3, and the overall work efficiency is improved by spraying the release agent on the internal molding cavity of the other movable mold 4.

[0065] like Figure 6 As shown, in this embodiment, the switching component includes:

[0066] A support frame 401 is fixed to the bottom of the two movable molds 4, and a sliding platform 402 is fixedly connected to the bottom of the support frame 401;

[0067] A driving module 403 for driving the sliding table 402 to move horizontally, wherein a sliding support 5 is fixedly connected to the bottom of the driving module 403, and the sliding support 5 is slidably connected to the top of the operating table 1;

[0068] A pushing hydraulic cylinder 501 is fixedly connected to the top of the operating table 1 , and a telescopic end of the pushing hydraulic cylinder 501 is fixedly connected to the sliding support 5 , so as to push the movable mold 4 to fit with the fixed mold 3 .

[0069] A top plate 400 is provided inside each of the two movable molds 4 , and a hydraulic rod is fixedly connected to the outer side of the movable mold 4 . The telescopic end of the hydraulic rod is fixedly connected to the top plate 400 , so as to push the formed model out of the movable mold 4 .

[0070] In the specific implementation, in this scheme, when it is necessary to switch the two movable molds 4, the hydraulic cylinder 501 is started to push the telescopic end of the hydraulic cylinder 501 to push the sliding support 5 to move toward the fixed mold 3. At this time, one of the two movable molds 4 fixedly connected to the sliding table 402 on the sliding support 5 fits with the fixed mold 3, thereby forming a completed injection mold. After cooling is completed, the sliding support 5 is pulled away from the fixed mold 3 by pushing the hydraulic cylinder 501, and the hydraulic cylinder inside the movable mold 4 pushes the workpiece inside to separate from the movable mold 4. , and a through groove is set on the operating table 1. The workpiece falls into the through groove and slides out, and then the sliding table 402 is driven to move left and right through the driving module 403. The driving module 403 can be an existing linear screw module, so that the two movable molds 4 spray the release agent alternately. The release agent can improve the demoulding effect of the mold and the finished product during the injection molding process, prevent adhesion, deformation or damage, and at the same time extend the service life of the mold and reduce the cost. The release agent can also be directly added to the resin to form a continuous and stable lubricating film, eliminating the trouble of constantly cleaning the mold.

[0071] like Figure 5 and Figure 7 As shown, embodiment 2: the fixed spraying structure includes:

[0072] A placement rack 7 is fixedly connected to one side of the fixed side plate 6, and a fixed nozzle 101 for atomization spraying is fixedly connected to the side of the placement rack 7 away from the fixed side plate 6;

[0073] A storage tank 10 is fixedly connected to one side of the fixed side plate 6, a connecting pipe for conveying is fixedly connected between the storage tank 10 and the fixed nozzle 101, a release agent is arranged inside the storage tank 10, and a conveying pump is arranged between the connecting pipe and the storage tank 10 for atomization and pressurization.

[0074] In specific implementation, when the movable mold 4 in use is close to the placement rack 7 on the fixed side plate 6, the delivery pump is started to spray the release agent inside the storage tank 10 into the movable mold 4 through the fixed nozzle 101, forming a layer of release agent protection mold, which is convenient for the later separation of the model from the movable mold 4.

[0075] like Figure 7 , Figure 8 and Fig. 9 As shown, in this implementation, the spraying structure is adjusted:

[0076] Two rotating plates 8 are respectively arranged on both sides of the placement frame 7, and the four rotating plates 8 are rotatably connected to the fixed side plate 6, and one end of the four rotating plates 8 is provided with a slide groove;

[0077] An adjusting member for adjusting the angle between two rotating plates 8 on the same side, the adjusting member includes limit plates 801 arranged on both sides of the placement frame 7, and a first electric push rod 803 is provided between the two limit plates 801 and the placement frame 7, the first electric push rod 803 is fixedly connected to the outside of the placement frame 7, the telescopic end of the first electric push rod 803 is fixedly connected to the limit plate 801, and a connecting shaft 802 is fixedly connected to the outside of the rotating plate 8, the connecting shaft 802 extends to the inside of the adjacent limit plate 801, and is slidably connected to the limit plate 801.

[0078] The regulating spray structure also includes:

[0079] A sliding block 9 is arranged inside the sliding groove of the rotating plate 8, and a second electric push rod 900 is fixedly connected to one end of the rotating plate 8. The telescopic end of the second electric push rod 900 passes through the rotating plate 8 and is fixedly connected to the sliding block 9, so as to push the sliding block 9 to slide inside the rotating plate 8;

[0080] A rotating rod 905 penetrates through the sliding block 9 and is rotatably connected to the sliding block 9, one end of the rotating rod 905 is fixedly connected to the connecting plate 901, and a first motor 904 is fixedly connected to the side of the sliding block 9 away from the connecting plate 901, and an output end of the first motor 904 is fixedly connected to the rotating rod 905, so as to drive the connecting plate 901 to rotate;

[0081] The annular nozzle 902 for spraying the release agent is fixedly connected to the outside of the connecting plate 901, and the outside of the annular nozzle 902 is fixedly connected to an output pipe 903 for providing the release agent, and the other end of the output pipe 903 is connected to the connecting pipe.

[0082] In the specific implementation, when the fixed spraying structure completes the spraying of the inside of the movable mold 4, but in the actual production process, for the packaging box, the molding cavity inside the movable mold 4 is often unable to be sprayed in place at the four corners, and for special positions, it is very easy to stick, so it is necessary to spray targeted at specific positions. Therefore, in this solution, a sliding block 9 is set inside one end of the rotating plate 8, and the position of the sliding block 9 inside the rotating plate 8 is adjusted by the second electric push rod 900. At the same time, the first motor 904 can be started, and the output shaft of the first motor 904 drives the rotating plate 8 to rotate. The movable rod 905 rotates, and the rotating rod 905 drives the connecting plate 901 to rotate and adjust, so that the annular nozzle 902 on the connecting plate 901 sprays the four corners in a targeted manner. At the same time, in order to increase the range of variation, the first electric push rod 803 between the two rotating plates 8 can be started, and the first electric push rod 803 drives the limiting plate 801 to move. The limiting plate 801 drives the two rotating plates 8 to adjust the angle through the connecting shaft 802 on the rotating plate 8, thereby completing the spraying of the four corners and special points inside the movable mold 4, ensuring that the release agent is sprayed comprehensively inside the movable mold 4.

[0083] Embodiment 3: Fig.10 , Fig.11 , Fig.12 and Fig.13 As shown, a mounting cylinder 11 is provided on the side of the connecting plate 901 away from the annular nozzle 902, and an opening is provided on the side of the mounting cylinder 11 close to the connecting plate 901, a fixing plate 117 is fixedly connected inside the mounting cylinder 11, and an inflatable airbag 112 is fixedly connected to the side of the fixing plate 117 close to the opening, an inflation component for inflating the airbag 112 is provided inside the mounting cylinder 11, a third electric push rod 110 is fixedly connected to the outside of the rotating rod 905 through a support plate, the telescopic end of the third electric push rod 110 is rotatably connected to the mounting cylinder 11, and is used to push the mounting cylinder 11 to pass through the connecting plate 901 and the annular nozzle 902 in sequence, when the third electric push rod 110 pushes the mounting cylinder 11 to move, the airbag 112 is inflated through the inflation component, the airbag 112 is tightly fitted to the inside of the movable mold 4, and the release agent is applied to the inside of the movable mold 4.

[0084] In specific implementation, when there are concave and convex parts inside the movable mold 4, the sprayed release agent is often blocked by the special shape of the cavity, and the release agent cannot be completely sprayed. Therefore, in this solution, based on the second embodiment, when the spraying mechanism is adjusted to spray the point, the third electric push rod 110 is started to push the installation cylinder 11 through the connecting plate 901 and the annular nozzle 902. When the installation cylinder 11 moves, the cleaning belt 124 inside the installation cylinder 11 expands. The cleaning belt 124 extends out from the inside of the mounting tube 11 and passes through the annular nozzle 902 together with the mounting tube 11. When the expanded cleaning belt 124 contacts the release agent on the outside of the annular nozzle 902, a large amount of release agent is on the surface. As the mounting tube 11 moves, the cleaning belt 124 contacts the concave and convex parts that need to be sprayed. Since the cleaning belt 124 is fully fitted with the concave and convex parts under the extrusion of the mounting tube 11, the release agent will be driven to be evenly wiped to the concave and convex parts, thereby completing the coating of the places that cannot be sprayed.

[0085] like Fig.13 As shown, in this embodiment, the inflatable component includes:

[0086] A movable disk 111 is arranged inside the mounting tube 11, and a gas cylinder 116 is fixedly connected between the side of the movable disk 111 away from the air bag 112 and one end inside the mounting tube 11, and a delivery pipe for gas delivery is arranged between the gas cylinder 116 and the air bag 112, and when the mounting tube 11 squeezes the gas cylinder 116, the gas filled inside the gas cylinder 116 rushes into the air bag 112;

[0087] An annular fixing frame 114 is sleeved on the outside of the mounting tube 11, and the annular fixing frame 114 is fixedly connected to the connecting plate 901. A plurality of sliding plates 115 are fixedly connected to the outside of the movable disk 111. The plurality of sliding plates 115 all pass through the mounting tube 11, and the sliding plates 115 are rotatably connected to the annular fixing frame 114, so as to support the movable disk 111.

[0088] In specific implementation, when the third electric push rod 110 pushes the installation cylinder 11 to move, the movable disk 111 inside the installation cylinder 11 is kept stationary by the sliding plate 115 and the annular fixing frame 114, and the installation cylinder 11 continuously squeezes the air cylinder 116, and the gas inside the air cylinder 116 rushes into the airbag 112, thereby completing the automatic inflation of the airbag 112, and when the installation cylinder 11 is reset later, the air cylinder 116 re-inhales the gas, causing the airbag 112 to shrink and re-enter the installation cylinder 11.

[0089] like Fig.11 and Fig.12 As shown, embodiment four: a plurality of limit strips 12 are fixedly connected to the outer side of the mounting tube 11, and the plurality of limit strips 12 are arranged in a ring around the mounting tube 11; an outer gear ring 121 is slidably connected to the outer side of the mounting tube 11; the outer gear ring 121 is sleeved on the outer side of the mounting tube 11 and is slidably connected to the mounting tube 11; the outer gear ring 121 is rotatably connected to the connecting plate 901; a gear 122 is meshingly connected to the outer side of the outer gear ring 121; a second motor 123 is fixedly connected to the outer side of the connecting plate 901; an output shaft of the second motor 123 is fixedly connected to the gear 122; an elastic cleaning belt 124 is provided at one end of the opening of the mounting tube 11; a camera 125 for shooting is fixedly connected to the side of the placement frame 7 close to the movable mold 4.

[0090] In a specific implementation, by setting a camera 125, the camera 125 shoots and observes the inside of the movable mold 4. When there is stickiness inside the movable mold 4, a cleaning belt 124 is set at the opening of the mounting cylinder 11. When the gear 122 expands, the cleaning belt 124 is driven to contact the inside of the movable mold 4 along with the gear 122. At this time, by starting the second motor 123, the second motor 123 drives the gear 122 to rotate, and the gear 122 drives the meshing outer gear ring 121 to rotate, and the limit strip 12 passes through the outer gear ring 121 and is slidably connected to the outer gear ring 121. The outer side of the mounting cylinder 11 drives the mounting cylinder 11 to rotate through the limiting strip 12 on the outer side of the mounting cylinder 11, ensuring that the outer gear ring 121 can drive the mounting cylinder 11 to rotate, and the mounting cylinder 11 will not be affected when it is close to the movable mold 4. When the mounting cylinder 11 rotates, the air bag 112 is driven to rotate together through the fixed plate 117, so that the cleaning belt 124 cleans the sticky place and wipes off the sticky matter. The cleaning belt 124 is made of sponge material. During the later spraying, the cleaning belt 124 will not cause any impact, and can also squeeze out the release agent by squeezing, thereby improving the wiping effect.

[0091] A forming method for a packaging box based on EPP material is also provided, comprising the following steps:

[0092] Step 1: fit one of the movable molds 4 to the fixed mold 3 by switching the components, and then fit the injection head of the injection molding machine 2 to the injection port of the fixed mold 3 by moving the module 201, and then perform injection molding;

[0093] Step 2: After the injection molding is cooled, the movable mold 4 is separated from the fixed mold 3 by switching components, and the workpiece inside the movable mold 4 is taken out;

[0094] Step 3: Use the switching component to refit the other movable mold 4 to the fixed mold 3, and switch the other movable mold 4 to the spraying component on one side of the fixed side plate 6 to spray the release agent on the used movable mold 4;

[0095] Step 4: The two movable molds 4 are alternately fitted with the fixed mold 3 for injection molding.
