Description

Technical Field

[0001] The invention relates to the technical field of injection molds, and in particular to an injection molding device for automobile interior decoration parts. Background Art

[0002] When manufacturing automotive interior parts, they are generally processed through injection molding equipment. During the processing, loose granular or powdered molding materials are first sent from the hopper of the injection molding machine into the high-temperature barrel for heating, melting and plasticization. Under the push of the screw, the melt is injected into the low-temperature closed mold. After a period of pressure holding, cooling and shaping time, the dynamic mold leaves the static mold to complete the mold opening, and the processed automotive interior parts can be taken out.

[0003] When pouring, the existing injection molding machines for automobile interior parts often shake as the raw materials are injected because the pouring pipe port is in a high temperature and high pressure state, and even cause the port to deform, causing the raw materials to overflow from the interface, resulting in affected injection molding quality. When the pouring pipe is detached after the pouring is completed, the residual raw materials in the pipe will leak out, which brings inconvenience to cleaning together with the raw materials overflowing during pouring. Therefore, an automobile interior parts injection molding equipment is proposed. Summary of the invention

[0015] 1. The present invention sets an anti-overflow glue component so that the docking motor drives the external threaded tube to rotate and move horizontally, so that one end of the external threaded tube starts to be screwed with one end of the pouring tube until the external threaded tube and the pouring tube are completely screwed together. At this time, the injection molding machine can start to inject into the static mold, and the threaded connection is used instead of the plug-in connection, so that the connection between the injection molding tube and the pouring tube is tighter, and the occurrence of glue overflow at the interface is effectively reduced;

[0016] 2. The present invention is provided with a control unit, so that as the external threaded tube moves horizontally, the rotating block at one end of the push rod contacts the push block inside the push hole, and pushes the inner sealing disk away from the outer sealing disk, so that the external threaded tube is connected, and then the injection molding can be started. When the injection molding is completed, the inner sealing disk will be reset to close the external threaded tube, thereby preventing the residual raw materials on the inner wall of the external threaded tube, the connecting tube, etc. from leaking out from one end of the external threaded tube, affecting the cleaning;

[0017] 3. The present invention sets a positioning assembly so that after the external threaded pipe and the pouring pipe are completely screwed together, the incomplete toothed ring drives the second sliding ring to slide laterally along the special-shaped pipe until each positioning rod is inserted into the positioning groove to position and clamp the pouring pipe and the external threaded pipe, thereby effectively preventing the pouring pipe and the external threaded pipe from being relatively offset and reducing the occurrence of glue overflow caused by loosening of the threads of the pouring pipe and the external threaded pipe;

[0018] 4. The present invention sets the positioning rod as a tapered structure that contracts laterally, so that the thinner end of the positioning rod can be inserted into the positioning groove more easily. As the positioning rod moves laterally, the gradually thickened part of the positioning rod will engage with the positioning groove until the positioning rod and the positioning groove are completely clamped, so that the connection between the two is tighter, and the positioning effect is prevented from being affected by the loose fit of the positioning rod and the positioning groove itself;

[0019] 5. The present invention provides a sealing collar, so that when the movable frame drives the positioning rod to position horizontally, the movable frame will drive the sealing collar to move horizontally on the static mold through the linkage frame until the movable frame covers the joint between the movable mold and the static mold and docks with the sealing collar seat, which can not only make the cooperation between the two closer and reduce the relative shaking of the movable mold and the static mold during injection molding, but also can closely adhere to the joint between the movable mold and the static mold to prevent glue overflow;

[0020] 6. The present invention provides a sealing component so that during injection molding, the raw materials inside the moving mold and the static mold will push the floating platform to one side by pressure until the floating platform fits with the truncated cone hole, so that the truncated cone hole is closed, thereby closing the pouring tube. When the raw materials inside the moving mold and the static mold are filled, the pouring tube is automatically closed to avoid glue overflow caused by excessive injection of raw materials.

[0021] 7. The present invention sets a recovery channel so that after the pouring tube is closed, excess raw materials will accumulate inside one end of the external threaded tube. At this time, the liquid pump inside the injection machine will use the recovery hose to recover the remaining raw materials inside the external threaded tube to the inside of the injection machine through the external sealing disk, the annular channel, and the recovery hose in sequence, thereby reducing the occurrence of glue overflow and recovering excess raw materials.

[0048] In summary: during the injection molding of the automobile interior parts injection molding equipment, the raw materials for injection molding are first put into the feed hopper 102, so that the raw materials are heated and melted inside the injection molding machine body 1 and injected into the injection machine 101, and then the injection molding machine body 1 drives the injection machine 101 to move toward the position of the mold end cover 5, and by setting the anti-overflow glue component, the anti-overflow glue component can drive the internal threaded tube 8 to rotate horizontally from the injection molding tube 7 through the cooperation of the first sliding ring 15 and the special-shaped tube 14, and then drive the external threaded tube 10 to rotate and move horizontally through the connecting tube 9, so that one end of the external threaded tube 10 begins to be screwed with one end of the pouring tube 6 until the external threaded tube 10 and the pouring tube 6 are completely screwed together, and then the injection molding can be started from the injection machine 101 to the inside of the static mold 4, and the threaded connection method is used. The method replaces the plug-in connection, so that the connection between the injection tube 7 and the pouring tube 6 is tighter, and the occurrence of glue overflow at the interface is effectively reduced. By setting the positioning component, the positioning component can position and clamp the pouring tube 6 and the externally threaded tube 10, effectively preventing the pouring tube 6 and the externally threaded tube 10 from being relatively offset, and reducing the occurrence of glue overflow caused by loose threads of the pouring tube 6 and the externally threaded tube 10. By setting the sealing component, the sealing component will automatically close the pouring tube 6 during injection molding, and the pouring tube 6 will be automatically closed when the raw materials inside the dynamic mold 3 and the static mold 4 are filled, so as to avoid glue overflow caused by excessive injection of raw materials. By setting the anti-glue overflow component, when injection molding is required, the docking motor 11 will drive the incomplete gear ring 13 to rotate through the transmission shaft 12, so that the incomplete gear ring 13 can rotate. The ring 13 gradually meshes with the first driven gear 16, thereby driving the internal threaded tube 8 to rotate horizontally from the injection tube 7 through the cooperation of the first sliding ring 15 and the special-shaped tube 14, and then driving the external threaded tube 10 to rotate and move horizontally through the connecting tube 9, so that one end of the external threaded tube 10 begins to be screwed with one end of the casting tube 6 until the external threaded tube 10 and the casting tube 6 are completely screwed together. At this time, injection molding can be started from the injection machine 101 to the inside of the static mold 4, and the threaded connection is used instead of the plug-in connection to make the connection between the injection tube 7 and the casting tube 6 tighter, effectively reducing the occurrence of glue overflow at the interface. By setting a control unit, in the process of screwing the external threaded tube 10 to the inside of the casting tube 6, as the external threaded tube 10 moves horizontally, the top of the casting tube 6 The rod 30 will gradually approach the outer sealing disk 26 inside the external threaded tube 10 until the rotating block 31 at one end of the push rod 30 contacts the top block 36 inside the top hole 37, and pushes the inner sealing disk 27 away from the outer sealing disk 26, compressing the first return spring rod 29 and separating the first plug block 32 and the second plug block 34 from the first plug hole 33 and the second plug hole 35 respectively, so that the external threaded tube 10 is connected, and the injection molding can be started at this time. When the injection molding is completed, the external threaded tube 10 spirally moves and separates from the pouring tube 6. At this time, the inner sealing disk 27 will be reset under the elastic force of the first return spring rod 29, and fit tightly with the outer sealing disk 26 to close the external threaded tube 10, thereby preventing the residual raw materials on the inner walls of the external threaded tube 10, the connecting tube 9, etc. from leaking from one end of the external threaded tube 10, affecting the cleaning.By setting the positioning assembly, after the external threaded tube 10 and the pouring tube 6 are completely screwed together, the incomplete toothed ring 13 will be separated from the first driven gear 16, rotate to one side of the second driven gear 18 and gradually mesh with the second driven gear 18, thereby driving the guide threaded tube 17 to rotate, so that the lifting screw inside the guide threaded tube 17 drives the moving frame 20 to move horizontally, thereby driving the second slip ring 21 to slide horizontally along the special-shaped tube 14 until each positioning rod 22 is inserted into the positioning groove 23 to position and clamp the pouring tube 6 and the external threaded tube 10, effectively preventing the pouring tube 6 and the external threaded tube 10 from being relatively offset, and reducing the pressure caused by the pouring tube 6 and the external threaded tube 10. The occurrence of glue overflow caused by loose threads can be avoided by setting a recovery channel 41, so that after the pouring tube 6 is closed, the excess raw material will accumulate at one end of the external threaded tube 10. At this time, the liquid pump inside the injection machine 101 will use the recovery hose 42 to recover the residual raw material inside the external threaded tube 10 through the outer sealing disk 26, the annular channel, and the recovery hose 42 to the injection machine 101 in sequence, thereby reducing the occurrence of glue overflow and recovering excess raw material. By setting the positioning rod 22 to a laterally contracted conical structure, the thinner end of the positioning rod 22 can be more easily inserted into the positioning groove 23, and as the positioning rod 22 moves laterally, the positioning rod 22 is The gradually thickened part of the positioning rod 22 will be clamped with the positioning groove 23 until the positioning rod 22 and the positioning groove 23 are completely clamped, so that the connection between the two is tighter, and the positioning effect is prevented from being affected by the looseness of the positioning rod 22 and the positioning groove 23. By setting the sealing ring 25, when the moving frame 20 drives the positioning rod 22 to be positioned horizontally, the moving frame 20 will drive the sealing ring 25 to move horizontally on the static mold 4 through the extrusion linkage frame 24 until the moving frame 20 covers the joint between the dynamic mold 3 and the static mold 4 and docks with the sealing sleeve seat 43, which can not only make the cooperation between the two closer, but also reduce the dynamic mold 3 and the static mold 4 during injection molding. The relative shaking generated can also prevent glue overflow by clinging to the joint of the movable mold 3 and the static mold 4. When the injection molding is completed, the movable frame 20 is reset, and the sealing ring 25 is reset synchronously under the elastic action of the second reset spring rod 44, which is convenient for the subsequent demoulding process. By setting the sealing component, during the injection molding, the raw materials inside the movable mold 3 and the static mold 4 will push the floating platform 38 to one side by pressure until the floating platform 38 fits with the truncated cone hole 39, so that the truncated cone hole 39 is closed, thereby closing the pouring tube 6, and realizing that when the raw materials inside the movable mold 3 and the static mold 4 are filled, the pouring tube 6 is automatically closed to avoid glue overflow caused by excessive injection of raw materials.
