Description

Technical Field

[0001] The utility model relates to the technical field of injection molding, in particular to a material guiding structure of an injection molding machine which is easy to disassemble. Background Art

[0002] The injection molding machine is the main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastic plastics or thermosetting plastics. When the existing injection molded parts are being injected, the material is introduced into the injection molding machine head through the material guide structure, and then the corresponding injection molding is carried out.

[0003] The material guiding mechanism of the existing injection molding machine mainly guides the material by setting a material guiding trough between the feed port and the barrel, so that the material can be added accurately. The material guiding trough is independently added by the cooperation of the pull rod and the accordion cover. In actual application, the length of the material guiding trough is relatively long. When the raw material in the injection molding machine is full, the device cannot control the injection molding raw material to stop flowing out in time, which easily causes waste of raw materials.

[0004] The patent document with the announcement number CN218928446U discloses a material guide structure for an injection molding machine. When the material is injected, the sleeve is slid downward so that the insertion rod contacts the block and squeezes the block open. At this time, the block does not block the retaining ring, and the injection molding material can flow out of the sleeve smoothly. When the injection molding is completed, the sleeve is slid upward. Under the action of the limiting structure, the block is reset to block the retaining ring, so that the injection molding material cannot flow out. In this way, the injection molding material can be controlled to stop flowing out in time to prevent the waste of raw materials.

[0005] However, the material guide structure of the injection molding machine causes air to enter along with the injection fluid when the injection fluid enters the mold, thereby causing the molding effect to deteriorate. Utility Model Content

In addition, during the injection molding process, because the upper mold and the lower mold are completely closed, the quality of injection molding can be improved.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1-Figure 4 The utility model provides a technical solution: a material guiding structure of an injection molding machine that is easy to disassemble, comprising an injection molding machine base 1 and a retaining frame 2 installed on the top of the injection molding machine base 1, an injection molding frame 3 is fixedly installed on the right side of the top of the retaining frame 2, and a baffle 1 5 and a baffle 2 are fixedly installed on the left and right sides of the top of the injection molding machine base 1 respectively, and two sliding rods 7 are fixedly connected between the baffle 1 5 and the baffle 2.

[0025] The injection molding frame 3 includes a pressing unit and a feeding unit; the pressing unit includes a hydraulic cylinder 301 and an extrusion tube 304, the feeding unit includes a fluid pipeline 302, an injection molding pipeline 303 and an injection head 305, the hydraulic cylinder 301 is fixedly installed on the top of the injection molding frame 3, the extrusion tube 304 is connected to the output end of the hydraulic cylinder 301, the fluid pipeline 302 is fixedly connected to the bottom of the inner wall of the injection molding frame 3, the injection head 305 is fixedly connected to the bottom of the fluid pipeline 302, the injection molding pipeline 303 is fixedly connected to the side of the fluid pipeline 302, the two injection molding pipelines 303 are connected to the inside of the fluid pipeline 302, the output end of the hydraulic cylinder 301 passes through the top of the injection molding frame 3 and is slidably connected to the inner wall through which it is penetrated, the diameter of the extrusion tube 304 is the same as the inner diameter of the injection molding pipeline 303, the injection head 305 passes through the bottom of the injection molding frame 3 and abuts against the inner wall through which it is penetrated, and the number of injection molding pipelines 303 is two and symmetrically distributed On both sides of the outer surface of the injection molding pipe 303, during injection molding, the hydraulic cylinder 1 301 is first started. The output end of the hydraulic cylinder 1 301 pushes the extrusion tube 304 downward to enter the interior of the fluid pipe 302. When the bottom end of the extrusion tube 304 is parallel to the two injection molding pipes 303, the hydraulic cylinder 1 301 is stopped to inject the raw material from the two injection molding pipes 303 into the interior of the fluid pipe 302. After the raw material is completely injected, the hydraulic cylinder 301 is started again to make the extrusion tube 304 slide inside the injection molding pipe 303, thereby pushing the raw material through the injection head 305 at a fixed flow rate into the injection mold. Because the diameter of the extrusion tube 304 is the same as the inner diameter of the fluid pipe 302, after the extrusion tube 304 enters the interior of the fluid pipe 302, a closed space is formed inside the fluid pipe 302, preventing gas from entering the interior of the fluid pipe 302 during the injection molding process, thereby ensuring the injection molding effect.

[0026] The outer surface of the slide bar 7 is equipped with an injection mold, which includes a mold base 6, a lower mold 601, a sliding block 1 602, an upper mold 603, a mold top plate 604, a sliding block 2 605 and a fixed rod 606. The sliding block 1 602 and the sliding block 2 605 are both slidably connected to the upper surface of the injection molding machine base 1, the mold base 6 is fixedly connected to the top of the sliding block 1 602, the mold top plate 604 is fixedly connected to the top of the sliding block 2 605, the lower mold 601 is fixedly connected to the right side of the mold base 6, and the upper mold 603 is fixedly connected to On the left side of the mold top plate 604, an injection hole in contact with the injection head 305 is opened on the upper surface of the upper mold 603, and a fixed rod 606 is fixedly connected to the left side of the baffle 2. The bottom of the lower mold 601 is fixedly connected to the top of the sliding block 1 602, and the bottom of the upper mold 603 is fixedly connected to the top of the sliding block 2 605. The right side of the mold top plate 604 is fixedly connected to the fixed rod 606.

Before injection molding, by starting the hydraulic cylinder 2 401, the output end of the hydraulic cylinder 2 401 pushes the push head 402 down When the extrusion frame 402 descends, the pushing head 402 pushes the extrusion frame 502. Because the two ends of the extrusion frame 402 are fixedly connected to the movable rod 1 501 and the movable rod 2 503 respectively, and the movable rod 1 501 and the movable rod 2 503 are movably connected to the right side of the baffle 1 5 and the left side of the mold base 6 respectively, during the descending process of the extrusion frame 402, the movable rod 1 501 and the movable rod 2 503 will be pushed to rotate at the connection between the right side of the baffle 1 5 and the left side of the mold base 6, and then the mold base 6 and the lower mold 601 will be pushed to drive the sliding block 1 602 to slide on the upper surface of the injection molding machine base 1. As the output end of the hydraulic cylinder 2 401 continues to descend, when the movable rod 2 503 rotates and is parallel, the upper mold 603 and the lower mold 601 will be forced to completely close to form an injection mold, thereby facilitating injection molding. In addition, during the injection molding process, because the upper mold 603 and the lower mold 601 are completely closed, the quality of injection molding can be improved.
