The thickness adjustment cylinder 29 is set to act on the core lifting rod 5 and the core mold 4, so as to adjust the size of the gap between the die 3 and the core mold 4, so as to achieve the effect of adjusting the thickness of the blank.

[0026] In actual application, each feed port is connected to an extruder. The material plug is composed of a material cylinder and flow dividers 1, 2, 3, 4, 5, 6, 7, 8, 9, and 10. Each flow divider has a flow channel for each layer of plastic to flow. The flow channels are independent of each other. When the plastic is in the extruder screw, it is heated and becomes a molten state.

[0027] When the material is empty, the first layer of plastic enters from the first layer plastic feed port 8, reaches the flow channel between the plug body 2 and the flow divider 18 under the pressure of the extruder, flows downward along the flow channel to point A, and enters the storage chamber from here;

[0028] The second and sixth layers of plastic enter from the second and sixth layers of plastic feed ports 9. When the plunger 6 is in the open state, the plastic enters the flow channels of the second and sixth layers respectively, and flows downward to points B and F, and enters the storage chamber. When the plunger drive cylinder 7 drives the plunger 6 to be in the closed state, the plastic can only enter the flow channel of the second layer of plastic, and the plastic can only enter the storage chamber from point B.

[0029] The third and seventh layers of plastic enter from the third and seventh layers of plastic feed ports 10. When the plunger 6 is in the open state, the plastic enters the flow channels of the third and seventh layers respectively, and flows downward to points C and G, and enters the storage chamber. When the plunger drive cylinder 7 drives the plunger 6 to be in the closed state, the plastic can only enter the flow channel of the third layer of plastic, and the plastic can only enter the storage chamber from point C.

[0030] The fourth and eighth layers of plastic enter from the fourth and eighth layers of plastic feed ports 11. When the plunger 6 is in the open state, the plastic enters the flow channels of the fourth and eighth layers respectively, and flows downward to points D and H, and enters the storage chamber. When the plunger drive cylinder 7 drives the plunger 6 to be in the closed state, the plastic can only enter the flow channel of the fourth layer of plastic, and the plastic can only enter the storage chamber from point D.

[0031] The fifth and ninth layers of plastic enter from the fifth and ninth layers of plastic feed ports 12. When the plunger 6 is in the open state, the plastic enters the flow channels of the fifth and ninth layers respectively, and flows downward to points E and I, and enters the storage chamber. When the plunger drive cylinder 7 drives the plunger 6 to be in the closed state, the plastic can only enter the flow channel of the fifth layer of plastic, and the plastic can only enter the storage chamber from point E.

[0032] The tenth layer of plastic enters from the tenth layer plastic feed port 13, and under the pressure of the extruder, reaches the flow channel between the splitter fluid nine 26 and the splitter fluid ten 27 and flows downward along the flow channel to point J, from where it enters the storage chamber;

[0033] When all the extruders extrude materials at the same time, each layer of plastic enters the storage chamber at the same time. In this process, the frequency converter that controls the speed of each extruder can be adjusted to control the extrusion amount of each layer of plastic, thereby controlling the thickness of each layer of plastic; as the amount of plastic in the storage chamber increases, the plug body 2 will rise under the action of the plastic until it reaches the highest point, completing the storage process. The machine head can use the plunger to drive the oil cylinder 7 to drive the plunger 6 to open and close the entrance of the four layers of plastic; achieving the effect of producing six, seven, eight, nine and ten layers according to needs;

[0034] After the material storage process is completed, the injection cylinder 28 starts to inject material, and the injection piston acts on the injection piston rod, the push rod (multiple rods evenly distributed), and the material plug body 2 to inject material downward until the lowest end, completing the injection process; during the entire injection process, the thickness adjustment cylinder 29 adjusts the thickness of the blank by acting on the core lifting rod 5 and the core mold 4 to adjust the size of the gap between the mouth mold 3 and the core mold 4.

[0035] The utility model can produce six, seven, eight, nine and ten layers as needed, and realizes one-time molding of multi-layer plastics. The layers of plastics are tightly fitted to each other, firm and leak-proof, and the versatility of the plastic container is realized. During the injection process, the molding die can be adjusted by using an injection thickness adjustment component, thereby adjusting the thickness of the molded plastic, so that the thickness of the multi-layer blank can be made uniform. After extrusion molding, the multi-layer blank is tightly combined to realize the functions of UV resistance, aging resistance, impact resistance, single-layer barrier, double-layer barrier, leakage prevention and anti-static, thereby extending the service life of the plastic container.

[0036] Although this specification is described according to implementation modes, not every implementation mode includes only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
