Description

Technical Field

[0002] Injection molding machine is also known as injection molding machine or injection machine. It is the main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastics or thermosetting plastics. It is divided into vertical, horizontal, and all-electric types. The injection molding machine can heat the plastic, apply high pressure to the molten plastic, and make it eject and fill the mold cavity. The role of the injection system: The injection system is one of the most important components of the injection molding machine. Generally, there are three main forms: plunger type, screw type, and screw injection plunger injection type. The most widely used is the screw type. Its function is that in one cycle of the injection molding machine, a certain amount of plastic can be heated and plasticized within a specified time, and then the molten plastic is injected into the mold cavity through the screw at a certain pressure and speed. After the injection is completed, the molten material injected into the mold cavity is kept in shape.

[0003] Masterbatch refers to a plastic colorant formed by a high proportion of pigments and additives and a well-dispersed thermoplastic resin. At present, the production of masterbatch generally adopts extrusion molding or injection molding, and injection molding is to use a screw to inject the molten mixed masterbatch into the mold cavity and then keep it fixed. When the injection molding machine is in use, the plastic granule raw materials are usually gradually dropped into the injection machine through the feed port on the injection machine for hot melt treatment and injection molding. However, when the plastic raw material particles are introduced from the feed port of the injection machine into the injection machine, the amount of plastic raw material particles entering the injection machine cannot be controlled, which will cause the plastic raw material particles to block the feed port, affecting the processing efficiency of the plastic raw material particles.

[0025] The second embodiment is based on the first embodiment. Figures 4 to 6 As shown, the material guide assembly 3 includes a fixed seat 33, a guide groove 34 is fixedly installed on the top of the fixed seat 33, a feed pipe 31 is fixedly installed on the top of the guide groove 34, a dispersing piece 36 is fixedly installed inside the feed pipe 31, connecting rods 35 are fixedly installed on both sides of the outer surface of the guide groove 34, a through groove 37 is opened inside the guide groove 34, and a positioning block 32 is fixedly installed on the surface of the top of the fixed seat 33 away from the guide groove 34. When manufacturing the masterbatch raw materials, the staff pours the plastic granule raw materials into the feed pipe 31, and the dispersing piece 36 is installed in the feed pipe 31. When the plastic granule raw materials are poured, the raw materials are distributed in the dispersing piece 36, and then the raw materials are transported to the guide groove 34 along the dispersing piece 36, so that the raw materials are introduced into the hot melt assembly 8 along the guide groove 34.

The shaking block 366 is arranged between the springs 362. When the springs 362 are shaken by the discharge of the granular raw materials, the shaking block 366 is driven to shake in the inner cover 364 to improve the fluidity of the raw material particles during discharge.

The staff places the masterbatch mold between the dynamic mold plate 64 and the positioning frame 66. After the injection is completed, the staff starts the hydraulic cylinder 7 to make the dynamic mold plate 64 slide on the surface of the tie rod 62, so that the dynamic mold plate 64 drives the mold to slide until it contacts the demolding assembly 65.

The support plate 651 is squeezed with the surface of the mold, and then the staff controls the extension and contraction of the hydraulic cylinder 7 to drive the support plate 651 to knock the mold, thereby shaking out the residual raw material in the mold to prevent the raw material from adhering to the mold after injection molding.

[0034] When in use, the staff pours the plastic raw material into the material guiding component 3, and then starts the motor to make the hot melt component 8 heat the raw material, and injects the melted raw material into the molding component 6. After the raw material is molded and dried, the staff starts the hydraulic cylinder 7 to make the movable template 64 move to the side of the demolding component 65, and knocks the mold through the demolding component 65 to facilitate cleaning of the mold.

When the plastic granule raw materials are poured, the raw materials are distributed in the dispersion piece 36, and then the raw materials are transported to the guide groove 34 along the dispersion piece 36, so that the raw materials are introduced into the hot melt component 8 along the guide groove 34.

[0036] When the staff pours the plastic raw material particles, the raw material slides downward along the inner cover 364. At this time, friction is generated between the raw material particles and the spring 362, so that the ball 363 set on the spring 362 collides with the inner cover 364 and knocks the inner cover 364. At this time, the raw material particles are knocked and slide to the bottom of the inner cover 364, so that the raw material particles are discharged from the guide hole 368 and transported to the discharge pipe 31 along the guide hole 368, so as to avoid the raw material particles being dense during the material guiding and causing the discharge pipe 31 to be blocked.

[0037] The shaking block 366 is arranged between the springs 362. When the springs 362 are shaken by the discharge of the granular raw materials, the shaking block 366 is driven to shake in the inner cover 364 to improve the fluidity of the raw material particles during discharge.

[0038] The staff starts the heater 81 to heat the barrel 82 , and starts the motor to rotate the injection screw 83 in the barrel 82 , so that the heated and melted raw material is transported along the injection screw 83 to one side of the molding component 6 , and then the melted raw material is injected into the mold from the nozzle 84 .

[0039] The staff places the masterbatch mold between the movable mold plate 64 and the positioning frame 66. After the injection is completed, the staff starts the hydraulic cylinder 7 to make the movable mold plate 64 slide on the surface of the pull rod 62, so that the movable mold plate 64 drives the mold to slide until it contacts the demolding assembly 65.

[0040] The support plate 651 is squeezed against the mold surface, and then the staff controls the extension and retraction of the hydraulic cylinder 7 to drive the support plate 651 to knock on the mold, thereby shaking out the remaining raw materials in the mold to prevent the raw materials from adhering to the mold after injection molding.
