Description

Technical Field

[0001] This application relates to the field of injection molding machine technology, specifically to a dual-injection-port injection molding machine. Background Technology

[0002] Injection molding machines, also known as injection molding machines or injection molding machines, are the main molding equipment used to produce various shapes of plastic products from thermoplastic or thermosetting plastics using plastic molds. They are classified as vertical, horizontal, and all-electric. Injection molding machines heat the plastic, apply high pressure to the molten plastic, and inject it to fill the mold cavity.

[0003] Existing injection molding machines generally have only one injection port, which means they can only perform injection molding on one type of mold and cannot perform injection molding on multiple molds at the same time, resulting in relatively low work efficiency. Summary of the Invention

[0004] The purpose of this application is to provide a dual-injection-gate injection molding machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this application specifically adopts the following technical solution:

[0006] A dual-injection-gate injection molding machine includes a machine body and further includes:

[0007] The injection molding mechanism includes two sliding seats symmetrically slidably mounted on the machine body. Each of the two sliding seats is horizontally and rotatably mounted with a spiral extrusion rod. Two transmission pipes are symmetrically mounted on the machine body. The end of the transmission pipe away from the sliding seat is the injection end. The two spiral extrusion rods are respectively movably inserted into the two transmission pipes. The top of the transmission pipe is connected to a feed box.

[0008] A drive assembly, mounted on the machine body, is used to drive the spiral extrusion rod to rotate;

[0009] A transmission assembly is mounted on the body and acts on the two sliding seats. The transmission assembly moves the two sliding seats closer to or further apart from each other. The transmission assembly has two adjustment components for adjusting the sliding positions of the two sliding seats respectively.

[0010] Furthermore, the transmission assembly includes a hydraulic cylinder mounted on the machine body, a connecting plate mounted on the movable shaft of the hydraulic cylinder, hinge rods symmetrically hinged on the connecting plate, sliding frames symmetrically and vertically slidably mounted on the machine body, the free ends of the two hinge rods respectively hinged to the two sliding frames, and the adjustment assembly symmetrically mounted on the two sliding frames.

[0011] Furthermore, the adjustment assembly includes a sliding block that is vertically slidably mounted on the sliding frame, an adjustment screw that is rotatably mounted on the sliding block, the adjustment screw being threaded through the sliding frame, and a linkage assembly that acts on the sliding seat is mounted on the machine body. When the sliding frame moves, the linkage assembly causes the sliding seat to move. When the sliding block moves within the sliding frame, the linkage assembly causes the sliding seat to move.

[0012] Furthermore, the linkage assembly includes a rotating rod, which is L-shaped and mounted on the machine body via a pivot between two linear segments. A movable groove is vertically provided on the sliding seat. A column rod is constructed on the rotating rod that is tangentially slidably connected to the movable groove. A through groove is provided along the length of the section of the rotating rod away from the column rod. A shaft rod is constructed on the sliding block that is tangentially slidably connected to the through groove.

[0013] Furthermore, a geared motor is installed on the machine body, and the drive assembly acts on the two spiral extrusion rods. When the geared motor rotates, the drive assembly causes the two spiral extrusion rods to rotate simultaneously and in opposite directions.

[0014] Furthermore, the drive assembly includes a first bevel gear mounted on the geared motor, and two second bevel gears symmetrically and rotatably mounted on the machine body, both meshing with the first bevel gear. A transmission rod is horizontally constructed on the second bevel gear. The transmission rod is polygonal and a transmission sleeve is slidably fitted on its outer periphery. The transmission sleeve is rotatably mounted on the sliding seat, and a gear assembly is installed between the transmission sleeve and the spiral extrusion rod.

[0015] Furthermore, the top of the feed box is open and cylindrical, the bottom of the feed box is conical and connected to a connecting pipe, the bottom of the connecting pipe is connected to the transmission pipe, a stirring rod is rotatably installed inside the feed box, and a power component for driving the stirring rod to rotate is installed on the feed box.

[0016] Furthermore, a rotating collar is rotatably fitted at the opening of the feed box, one end of the stirring rod is constructed on the rotating collar, the power assembly includes an external gear ring rotatably fitted on the outer periphery of the rotating collar, a connecting frame is constructed on the outside of the feed box, a drive gear is rotatably mounted on the connecting frame via a rotating shaft, the drive gear meshes with the external gear ring, a third bevel gear is mounted on the rotating shaft, a fourth bevel gear meshes with the third bevel gear is rotatably mounted on the connecting frame, a rhomboid rod is slidably fitted on the fourth bevel gear, and the rhomboid rod is connected to the gear assembly.

[0017] Furthermore, the stirring rod has a vertical section and an inclined section, the vertical section is connected to the rotating collar, and the free end of the inclined section is close to the central axis of the feed box.

[0018] Furthermore, a sealing sleeve is threaded onto one end of the transmission tube near the sliding seat, and a sealing ring is installed inside one end of the sealing sleeve, the sealing ring abutting against one end of the transmission tube.

[0019] The beneficial effects of this application are as follows:

[0020] Compared with the prior art, this application adjusts the initial position of the sliding seat by adjusting the component. After adjustment, the driving component makes the two sliding seats move simultaneously and in opposite directions, thereby forming a spiral extrusion rod moving in the transfer tube. During the movement, the spiral extrusion rod will squeeze the raw material inside the transfer tube, thereby squeezing the raw material inside the transfer tube from the injection end into the mold, thus realizing batch injection molding of two molds at the same time, thereby improving work efficiency.

[0021] When the output shaft of the geared motor of this application rotates, the two spiral extrusion rods will rotate simultaneously and in opposite directions through the drive assembly, so that the rotation of the two spiral extrusion rods can be achieved by one geared motor, thereby saving energy consumption.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0029] like Figures 1-5 As shown, one embodiment of this application discloses a dual-injection-gate injection molding machine, which includes a machine body 1 and further includes:

[0030] The injection molding mechanism includes two sliding seats 2 symmetrically slidably mounted on the machine body 1. Each of the two sliding seats 2 is horizontally and rotatably mounted with a spiral extrusion rod 3. Two transmission pipes 5 are symmetrically mounted on the machine body 1. The end of the transmission pipe 5 away from the sliding seat 2 is the injection end, which is used to connect with the injection mold. With the addition of a demolding mechanism, an injection molding machine is formed. The two spiral extrusion rods 3 are respectively movably inserted into the two transmission pipes 5. The top of the transmission pipe 5 is connected to a feed box 6. Specifically, a heating ring is installed on the transmission pipe 5 to heat the raw material inside the transmission pipe 5, which is consistent with the existing structure.

[0031] The drive assembly 7 is mounted on the machine body 1 and is used to drive the screw extrusion rod 3 to rotate. The screw extrusion rod 3 is a screw used inside an existing injection molding machine for conveying and extruding raw materials.

[0032] The transmission assembly 8, mounted on the machine body 1, acts on the two sliding seats 2. The transmission assembly 8 moves the two sliding seats 2 closer together or further apart. The transmission assembly 8 has two adjusting components 9, which are used to adjust the sliding positions of the two sliding seats 2 respectively. In use, the raw material is first poured into the two feed boxes 6. Then, the drive assembly 7 rotates the screw extrusion rod 3. During rotation, the screw extrusion rod 3 causes the raw material in the feed box 6 to enter the corresponding transmission pipe 5, thus filling the transmission pipe 5 with raw material. Because the molds at the injection ends of the two transmission pipes 5 are different, the subsequent travel of the screw extrusion rod 3 is also different. Therefore, the travel of the sliding seats 2 needs to be adjusted beforehand using the adjusting components 9. After adjustment, the drive assembly 7 moves the two sliding seats 2 simultaneously and in opposite directions. The spiral extrusion rod 3 moves in the opposite direction because it is rotatably mounted on the sliding seat 2. Therefore, the movement of the sliding seat 2 causes the spiral extrusion rod 3 to move, thus forming a spiral extrusion rod 3 moving within the transfer tube 5. During this movement, the spiral extrusion rod 3 extrudes the raw material inside the transfer tube 5, forcing the raw material from the injection end into the mold. This allows for simultaneous injection molding of two different molds through two transfer tubes 5. After injection molding, during mold demolding, the drive assembly 7 brings the two sliding seats 2 closer together, causing the two spiral extrusion rods 3 to move closer together. After mold demolding, the drive assembly 7 again causes the two spiral extrusion rods 3 to extrude the corresponding raw material inside the transfer tube 5, and so on. This allows for simultaneous batch injection molding of two different molds, thereby improving work efficiency.

[0033] like Figure 1 and Figure 4 As shown, in some embodiments, the transmission assembly 8 includes a hydraulic cylinder 801 mounted on the machine body 1. A connecting plate 802 is mounted on the movable shaft of the hydraulic cylinder 801. Hinge rods 803 are symmetrically hinged on the connecting plate 802. Sliding frames 804 are symmetrically and vertically slidably mounted on the machine body 1. The free ends of the two hinge rods 803 are respectively hinged to the two sliding frames 804. The adjusting assembly 9 is symmetrically mounted on the two sliding frames 804. That is, when the movable shaft of the hydraulic cylinder 801 moves, it will drive the connecting rods 803 mounted on its movable shaft. When the plate 802 moves, the connecting plate 802 will drive the two hinge rods 803 hinged to the connecting plate 802 to move. Since one end of the hinge rod 803 is hinged to the sliding frame 804, when the connecting plate 802 moves, the hinge rod 803 will drive the two sliding frames 804 to move vertically. When the sliding frame 804 moves, the corresponding sliding seat 2 will move through the adjusting component 9. The two sliding frames 804 are driven to move by a hydraulic cylinder 801, thereby saving energy.

[0034] like Figures 1-4As shown, in some embodiments, the adjusting component 9 includes a sliding block 901 vertically slidably mounted on the sliding frame 804. An adjusting screw 902 is rotatably mounted on the sliding block 901, and the adjusting screw 902 is threaded through the sliding frame 804. A linkage component 10 acting on the sliding seat 2 is mounted on the machine body 1. When the sliding frame 804 moves, the sliding seat 2 moves through the linkage component 10. When the sliding block 901 moves within the sliding frame 804, the sliding seat 2 moves through the linkage component 10. That is, when the adjusting screw 902 is rotated, it will cause the adjusting screw 902 to move spirally. Because the adjusting screw 902 is rotatably engaged with the sliding block 901, rotating the adjusting screw 902 will cause the sliding block 901 to move vertically, thereby causing the sliding seat 2 to move through the linkage component 10, thus adjusting the initial position of the sliding seat 2. Then, when the two sliding frames 804 move simultaneously, the two sliding seats 2 have different travel distances, resulting in the two spiral extrusion rods 3 moving in opposite directions but with different travel distances.

[0035] like Figures 1-4 As shown, in some embodiments, the linkage assembly 10 includes a rotating rod 1001, which is L-shaped and mounted on the body 1 via a pivot between two linear segments. A vertically opening movable slot 1002 is provided on the sliding seat 2. A column rod 1003 is constructed on the rotating rod 1001, slidingly tangential to the movable slot 1002. A through slot 1004 is formed along the length of the section of the rotating rod 1001 away from the column rod 1003. A shaft rod 1005 is constructed on the sliding block 901, slidingly tangential to the through slot 1004. That is, when the sliding block 901 is rotated, the movement of the sliding block 901 indirectly drives the shaft rod 1005 mounted on the sliding block 901 to move. Because the shaft rod 1005 is slidingly tangential to the through slot 1004, the sliding block 901... During movement, relative to the rotating rod 1001, the shaft 1005 moves within the slot 1004 and rotates along its own axis, thereby forcing the rotating rod 1001 to rotate. Because the column rod 1003 on the rotating rod 1001 is tangentially sliding with the movable slot 1002, when the rotating rod 1001 rotates, relative to the sliding seat 2, the column rod 1003 moves within the movable slot 1002 and rotates along its own axis, thereby forcing the sliding seat 2 to move. Since the rotation angles of the two rotating rods 1001 are different at this time, when the sliding frame 804 moves, the movement of the sliding frame 804 indirectly drives the sliding block 901 to move, thereby causing the sliding seat 2 to move. Thus, the two sliding frames 804 move simultaneously, but the sliding strokes of the two sliding seats 2 are different.

[0036] like Figures 1-3As shown, in some embodiments, a geared motor 11 is installed on the body 1, and the drive assembly 7 acts on the two spiral extrusion rods 3. When the geared motor 11 rotates, the drive assembly 7 causes the two spiral extrusion rods 3 to rotate simultaneously and in opposite directions. That is, when the output shaft of the geared motor 11 rotates, the drive assembly 7 causes the two spiral extrusion rods 3 to rotate simultaneously and in opposite directions, which facilitates the driving action.

[0037] like Figures 1-5 As shown, in some embodiments, the drive assembly 7 includes a first bevel gear 701 mounted on the geared motor 11. Two second bevel gears 702, each meshing with the first bevel gear 701, are symmetrically and rotatably mounted on the body 1. A transmission rod 703 is horizontally mounted on each of the second bevel gears 702. The transmission rod 703 is polygonal, and a transmission sleeve 704 is slidably fitted on its outer periphery. The transmission sleeve 704 is rotatably mounted on the sliding seat 2. A gear assembly 705 is installed between the transmission sleeve 704 and the spiral extrusion rod 3. In this embodiment, the gear assembly 705 consists of two meshing gears, one mounted on the transmission sleeve 704 and the other mounted on the spiral extrusion rod 3. When the sliding... When the movable seat 2 moves, because the transmission sleeve 704 is rotatably mounted on the sliding seat 2, the sliding seat 2 will slide on the transmission rod 703. When the output shaft of the reduction motor 11 rotates and drives the first bevel gear 701 to rotate, the rotation of the first bevel gear 701 will drive the two second bevel gears 702 to rotate, so that the two transmission rods 703 connected to the second bevel gears 702 will rotate in opposite directions. Because the transmission rod 703 and the transmission sleeve 704 are in a sliding fit relationship, the rotation of the transmission rod 703 will drive the transmission sleeve 704 to rotate, which will cause the spiral extrusion rod 3 to rotate through the gear assembly 705. The rotation of the spiral extrusion rod 3 does not affect the normal movement of the sliding seat 2.

[0038] like Figure 3 and Figure 5 As shown, in some embodiments, the top of the feed box 6 is open and cylindrical, and the bottom of the feed box 6 is conical and connected to a connecting pipe 16. The bottom of the connecting pipe 16 is connected to the transmission pipe 5. A stirring rod 12 is rotatably installed inside the feed box 6, and a power assembly 13 is installed on the feed box 6 to drive the stirring rod 12 to rotate. The design of the stirring rod 12 can prevent the raw material from getting stuck in the transmission pipe 5, ensuring the flow of the raw material in the feed box 6. The stirring rod 12 can be continuously rotated by the power assembly 13.

[0039] like Figures 1-5As shown, in some embodiments, a rotating collar 14 is rotatably fitted at the opening of the feed box 6. One end of the stirring rod 12 is constructed on the rotating collar 14. The power assembly 13 includes an external gear ring 1301 rotatably fitted on the outer periphery of the rotating collar 14. A connecting frame 1302 is constructed on the outer side of the feed box 6. A drive gear 1303 is rotatably mounted on the connecting frame 1302 via a rotating shaft. The drive gear 1303 meshes with the external gear ring 1301. A third bevel gear 1304 is mounted on the rotating shaft. A fourth bevel gear 1305 meshes with the third bevel gear 1304 and is rotatably mounted on the connecting frame 1302. A rhomboid rod 1306 is slidably fitted on the fourth bevel gear 1305. The rhomboid rod 1306 is connected to the gear assembly 705. In this embodiment, the gear assembly 705 includes three gears. Gears are installed on the transmission sleeve 704, the spiral extrusion rod 3, and the rhomboid rod 1306. Therefore, the gear on the rhomboid rod 1306 meshes with the gear on the spiral extrusion rod 3. The gear 704 meshes with the gear of the spiral extrusion rod 3. Therefore, when the spiral extrusion rod 3 rotates, it will drive the rhomboid rod 1306 to rotate. This will cause the fourth bevel gear 1305, which is slidably engaged with the rhomboid rod 1306, to rotate. The rhomboid rod 1306 and the fourth bevel gear 1305 are slidably engaged, and the fourth bevel gear 1305 is rotatably mounted on the connecting frame 1302. Therefore, when the spiral extrusion rod 3 moves horizontally, it does not affect the normal rotation of the fourth bevel gear 1305. When the fourth bevel gear 1305 rotates, it will drive the third bevel gear 1304, which meshes with it, to rotate. This will drive the drive gear 1303 to rotate. Because the drive gear 1303 meshes with the external gear ring 1301, the rotating collar 14 is rotated. Because the rotating collar 14 is connected to the stirring rod 12, the stirring rod 12 will move within the feed box 6, thus eliminating the need for an additional drive component to rotate the stirring rod 12.

[0040] like Figure 1 and Figure 5 As shown, in some embodiments, the stirring rod 12 has a vertical section and an inclined section. The vertical section is connected to the rotating collar 14, and the free end of the inclined section is close to the central axis of the feed box 6. The design of the inclined section of the stirring rod 12 can effectively prevent blockage at the connection between the connecting pipe 16 and the feed box 6, and further improve the flowability of raw materials inside the feed box 6.

[0041] like Figure 1 and Figure 5 As shown, in some embodiments, a sealing sleeve 15 is threaded onto one end of the transmission pipe 5 near the sliding seat 2, and a sealing ring 4 is installed inside the sealing sleeve 15. The sealing ring 4 abuts against one end of the transmission pipe 5. The design of the sealing sleeve 15 and the sealing ring 4 can prevent the raw material from seeping out from the joint between the transmission pipe 5 and the spiral extrusion rod 3, thus playing a protective role.

[0042] The above description of the disclosed embodiments enables those skilled in the art to make or use this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
