[0002] When the plunger injection molding machine is in use, the raw material is directly pushed into the plasticizing cavity at the front end of the barrel by the plunger, and then the raw material is injected into the plastic molding mold to form plastic products of various shapes. However, it is difficult to achieve uniform mixing of the raw materials only by squeezing the raw materials by the plunger, or once the raw materials enter the barrel for a long distance, the squeezing effect of the plunger on the raw materials is reduced, and it is difficult to achieve uniform mixing of the raw materials. In addition, since the heating device is added to the outside of the barrel, the heating effect of the raw materials inside the barrel is not good because the heating device is far away from the raw materials in the barrel, and the uniform mixing of the raw materials cannot be achieved.

[0046] After the plunger 24 moves backward, the injection molding material is fed into the equipment box 1 through the feeding hopper 6. When the plunger 24 moves forward, the injection molding material inside the equipment box 1 can be squeezed into the extrusion barrel;

[0047] A transverse shaft 26 is connected to the middle of the rear end of the plunger 24, and the driving mechanism inside the equipment box 1 is used to drive the plunger 24 to rotate through the transverse shaft 26;

[0054] The rear end of the horizontal shaft 26 is connected to the ejection mechanism at the rear end of the equipment box 1 through a rotating connection assembly, and the ejection mechanism realizes the forward and backward movement of the plunger 24 inside the barrel 5 through the rotating connection assembly and the horizontal shaft 26;

[0056] Such an arrangement enables the connection between the connecting rod 15 and the horizontal axis 26 to be achieved while also satisfying the rotation of the horizontal axis 26; when the horizontal axis 26 and the plunger 24 rotate, the stirring protrusion 25 at the front end of the plunger 24 is used to stir the injection molding material inside the barrel 5, and when the plunger 24 moves forward, the injection molding material is further plasticized to improve the uniformity of the injection molding material.

[0060] A reserved opening 22 is provided in the middle of the end cover plate 2 for rotating the connecting assembly to move forward and backward.

[0061] When the hydraulic cylinder 16 controls the piston rod 14 to extend and retract through the piston plate 21, the connecting plate 3 drives the horizontal shaft 26 and the plunger 24 to move backward and forward through the connecting rod 15;

[0062] The front end of the barrel 5 is connected to an extrusion barrel, the front end of the extrusion barrel is connected to a conical extrusion head 12, an extrusion screw is arranged inside the extrusion barrel, and a toggle bump 45 is arranged at the rear end of the extrusion screw;

[0063] The extrusion barrel includes a conical barrel 8 fixedly connected to the front end of the barrel 5 and a circular barrel 10 integrally connected to the front end of the conical barrel 8. A rear heating barrel seat 9 is fixed to the outside of the conical barrel 8, and a rear heating wire 46 is integrated inside the rear heating barrel seat 9. Several groups of front heating barrel seats 11 are fixed at equal intervals on the outside of the circular barrel 10, and a front heating wire 47 is integrated inside the front heating barrel seat 11.

[0064] The front heating wire 47 and the rear heating wire 46 are energized to further heat the injection molding materials in the circular cylinder 10 and the conical cylinder 8 respectively. Combined with the front end extrusion rod 40 and the conical extrusion head 42, the extrusion of the injection molding materials is beneficial to improve the plasticization efficiency of the injection molding materials.

[0065] When the plunger 24 moves forward, under the action of a strong extrusion force, the injection molding raw material is plasticized and pushed into the tapered barrel 8, and the tapered barrel 8 is set to be narrow at the front and wide at the back, and the tapered extrusion head 42 is also set to be narrow at the front and wide at the back, so that the injection molding raw material quickly enters the gap between the tapered extrusion head 42 and the tapered barrel 8, which can reduce the space of the injection molding raw material moving backward, thereby further realizing the extrusion of the injection molding raw material, which is conducive to the rapid plasticization of the injection molding raw material;

[0066] The extrusion disc 49 is fixed inside the connection between the circular cylinder 10 and the conical cylinder 8;

[0067] The extrusion screw includes a front extrusion rod 40 located inside the circular barrel 10 and a conical extrusion head 42 located inside the conical barrel 8, and the conical extrusion head 42 is integrally formed and connected to the rear end of the front extrusion rod 40;

[0068] The rear end of the front extrusion rod 40 passes through the middle of the extrusion disc 49, and the surface of the front extrusion rod 40 is provided with a front extrusion spiral blade 41, and the surface of the conical extrusion head 42 is provided with a plurality of groups of rear extrusion spiral blades 43 at equal intervals in front and back;

[0069] The front end of the barrel 5 is fixed to the rear end of the conical barrel 8 through the first flange 7, the rear end of the conical extrusion head 12 is fixed to the front end of the circular barrel 10 through the second flange 13, and an extrusion hole 48 with a narrow front and a wide rear is centrally arranged inside the conical extrusion head 12.

[0070] An integrally formed conical head 44 is disposed at the rear end of the conical extrusion head 42 , and the conical head 44 is wide at the front and narrow at the rear, and a moving protrusion 45 is fixed on the surface of the conical head 44 .

[0071] like Fig.12 As shown, after the plunger 24 moves forward, the plunger 24 drives the conical extrusion head 42 and the front end extrusion rod 40 to rotate through the cooperation of the stirring protrusion 25 and the toggle protrusion 45, and the extrusion spiral blades 43 on the conical extrusion head 42 extrude and stir the injection molding material passing through the gap between the conical extrusion head 42 and the conical barrel 8, and the pitch between the front and rear groups of rear extrusion spiral blades 43 gradually decreases, so that the more the injection molding material is extruded forward, the greater the extrusion force of the rear extrusion spiral blades 43 is, and the injection molding material is further plasticized;

[0072] The extrusion barrel is further provided with an extrusion disc 49 movably sleeved on the extrusion screw, and the extrusion disc 49 is provided with extrusion grooves 50 at equal intervals, and the extrusion disc 49 is further integrated with internal heating wires 32 located at the upper and lower ends of the extrusion grooves 50. Such a configuration can further reduce the distance between the internal heating wires 32 and the injection molding raw material when the injection molding raw material passes through the extrusion grooves 50, thereby further improving the effect of heating the injection molding raw material, and further improving the plasticizing effect of the injection molding raw material when the injection molding raw material passes through the extrusion grooves 50.

[0073] Subsequently, the rear extrusion spiral blade 43 squeezes the injection molding material into the circular cylinder 10 through the extrusion groove 50. The arrangement of the extrusion groove 50 further reduces the space of the injection molding material moving backward, thereby further squeezing the injection molding material, which is beneficial to the rapid plasticization of the injection molding material.

[0074] And the internal heating wire 32 is used to heat the injection molding material passing through the extrusion groove 50 after being energized, so as to further improve the plasticization efficiency of the injection molding material;

[0075] After the injection molding material is squeezed into the interior of the circular cylinder 10 through the extrusion groove 50, the front extrusion spiral blade 41 on the front extrusion rod 40 continues to extrude and transport the injection molding material until the injection molding material is squeezed into the injection mold through the extrusion hole 48 in the conical extrusion head 12;

[0076] When the plunger 24 rotates, the stirring protrusion 25 provided at the front end of the plunger 24 is used to stir the injection molding material inside the barrel 5, and when the plunger 24 moves forward and squeezes the injection molding material inside the barrel 5 into the extrusion barrel, the plunger 24 drives the extrusion screw to rotate through the cooperation of the stirring protrusion 25 and the shifting protrusion 45, and the extrusion screw further squeezes the injection molding material inside the extrusion barrel, so that the injection molding material is extruded through the extrusion groove 50. At the same time, the internal heating wire 32 is used to heat the injection molding material passing through the extrusion groove 50 until the injection molding material inside the extrusion barrel is extruded through the conical extrusion head 12.
