Description

Technical Field

[0001] The utility model relates to the technical field of injection molding machines, and particularly relates to a double-port injection molding device that can be efficiently replaced. Background Technique

[0002] An injection molding machine is the main equipment for plastic product molding processing. There is a mold in the injection molding machine. The plastic particles in the hopper are heated and extruded into the mold through an extrusion mechanism, and then the mold is opened to make plastic products with the same shape as the cavity in the mold. Some plastic products need to use the two-color injection molding process during processing. By cooperating the injection nozzle with the two-color injection mold, one kind of plastic is injected in the inner layer, and when injecting the outer layer, another kind of plastic is injected when injecting the outer layer through the change of the cavity and the change of the flow path of the injection nozzle, so as to realize two-color injection molding processing.

[0003] However, in the prior art, the installation structure of the existing two-color injection nozzle for injection molding machines is relatively complex, which makes it cumbersome for workers to disassemble and assemble during maintenance and repair, and also increases the working intensity of workers.

Detailed Embodiment

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1-4, including a connecting plate 1 and two groups of feed pipes 2 fixed to the back of the connecting plate 1, a limiting chute 3, which is fixedly arranged in a U-shape on the side of the connecting plate 1 away from the feed pipes 2; a movable plate 4, which is inserted into the limiting chute 3 through the opening on one side of the limiting chute 3. Through holes are provided at both sides of the surface of the movable plate 4, which facilitates removing the movable plate 4 from the inside of the limiting chute 3; an injection nozzle 5, which is fixed to the surface of the movable plate 4. At the position corresponding to the feed pipe 2 on the injection nozzle 5, there is a plug connector that can be inserted into the inside of the feed pipe 2. When the movable plate 4 is inserted into the limiting chute 3, the plug connector of the injection nozzle 5 fits against the side wall of the connecting plate 1. When one side of the movable plate 4 abuts against the inner wall of the limiting chute 3, that is, the plug connector of the injection nozzle 5 corresponds to the feed pipe 2. Push the movable plate 4 towards the connecting plate 1 to connect the injection nozzle 5 with the feed pipe 2, achieving the purpose of quick assembly; a limiting ring 6, which is fixed to the outer surface of the plug connector of the injection nozzle 5. On the surface of the connecting plate 1, there is an invisible groove corresponding to the limiting ring 6. When the movable plate 4 is pushed towards the connecting plate 1, the limiting ring 6 moves with the movable plate 4 and gradually enters the invisible groove, reducing the presence of the limiting ring 6 between the connecting plate 1 and the movable plate 4, and limiting the depth of the injection nozzle 5 into the feed pipe 2; a pressing block 7, which is movably installed at the feed inlet of the limiting chute 3 through a rotating shaft. A buckle is fixed to the side of the bottom of the pressing block 7 close to the limiting chute 3. A clamping groove is provided on the side wall of the limiting chute 3 corresponding to the pressing block 7. When the movable plate 4 is installed into the limiting chute 3, rotate the pressing block 7 downward towards the limiting chute 3, so that one side of the pressing block 7 enters the inside of the limiting chute 3 and pushes the movable plate 4 towards the inner wall of the limiting chute 3. When the pressing block 7 rotates to be perpendicular to the ground, the pressing block 7 pushes the movable plate 4 to completely fit against the inner wall of the limiting chute 3, thus achieving the purpose of quickly positioning the limiting chute 3 and making the injection nozzle 5 correspond to the feed pipe 2. And when the pressing block 7 is perpendicular to the ground, the clamping block opening of the pressing block 7 enters the clamping groove to lock the pressing block 7 and prevent the movable plate 4 from being misaligned when it moves; a limiting rod 12, which is movably installed on the movable plate 4 through a fixed rotating shaft on the surface of the movable plate 4. A knob is fixed to the side of the limiting rod 12 away from the movable plate 4. When pushing the movable plate 4 to insert the injection nozzle 5 into the feed pipe 2, the limiting rod 12 can be rotated through the knob, so that both ends of the limiting rod 12 are respectively stuck in the limiting chute 3. Both sides of the limiting rod 12 are respectively in contact with the movable plate 4 and the inner wall of the limiting chute 3, squeezing the limiting chute 3 and the movable plate 4, thereby restricting the movement of the injection nozzle 5 and preventing the movable plate 4 from automatically separating from the feed pipe 2.

[0026] An installation groove 8 is provided at the position where the limiting slide groove 3 fits the connecting plate 1. The limiting plate 9 is inserted between the movable plate 4 and the connecting plate 1 through the installation groove 8. A pull ring is provided on one side of the outer wall of the limiting plate 9, and the limiting plate 9 is conveniently moved through the pull ring. A positioning groove 10 is provided at the position of the limiting plate 9 corresponding to the injection nozzle 5, and an invisible groove is provided at the position of the positioning groove 10 close to the limiting ring 6. When the limiting plate 9 is inserted between the connecting plate 1 and the movable plate 4 from the installation groove 8, the limiting ring 6 is naturally engaged with the limiting ring 6, further eliminating the presence of the limiting ring 6, and at the same time, the position of the limiting ring 6 is squeezed and restricted to prevent the injection nozzle 5 from detaching from the inside of the feed pipe 2. A magnet 11 is fixed at the center position of the connecting plate 1 away from the feeding pipe 2. When the two limit plates 9 are respectively inserted from the top and bottom of the limit slide groove 3 into between the movable plate 4 and the connecting plate 1, the limit plates 9 are adsorbed by the magnet 11 to reduce the risk of the limit plates 9 automatically detaching from the mounting groove 8 and enhance the fixing effect of the injection nozzle 5.

[0027] Working principle: when it is necessary to replace different injection nozzles 5, the two limit plates 9 are moved in the direction away from the limit slide groove 3 through the pull rings, so that the invisible groove of the limit plate 9 releases the restriction on the limit ring 6, and then the limit rod 12 is rotated by the knob on the surface of the limit rod 12 to make the side wall of the limit rod 12 staggered with the inner wall of the limit slide groove 3, thereby facilitating the movable plate 4 to move in the direction away from the feeding pipe 2, and the plug connector of the injection nozzle 5 is disengaged from the inside of the feeding pipe 2 by pulling the movable plate 4, and the pressing block 7 is rotated to the outside of the limit slide groove 3 to make one side of the limit slide groove 3 unblocked, and then the movable plate 4 is controlled to move to the outside of the limit slide groove 3 through the through hole on the surface of the movable plate 4, so that the two groups of injection nozzles 5 are disengaged from the connecting plate 1 at the same time, thereby improving the disassembly and assembly efficiency of the injection nozzle 5, and the injection nozzle 5 of the appropriate size is connected to the limit slide groove 3 during installation, so that the movable plate 4 can be simultaneously After the two groups of injection nozzles 5 are assembled, the movable plate 4 is inserted into the limiting slide 3 from the feed port of the limiting slide 3, and the movable plate 4 is pushed to continue to move into the limiting slide 3 by rotating the pressure block 7. When the movable plate 4 is in a vertical state with the ground, the alignment of the injection nozzle 5 and the feed pipe 2 is completed to achieve the purpose of rapid positioning. After the pressure block 7 is vertical to the ground, the buckle at the bottom of the pressure block 7 is plugged into the card slot, which limits the movement of the pressure block 7 while also limiting the movement of the movable plate 4. The movable plate 4 is pushed toward the feed pipe 2 to complete the docking of the injection nozzle 5 with the feed pipe 2, and then the limiting rod 12 is rotated to limit the movable plate 4 between the limiting rod 12 and the limiting ring 6 to prevent the injection nozzle 5 from detaching from the feed pipe 2, and then the two groups of limiting plates 9 are respectively inserted from the inside of the mounting groove 8 to further limit the movement of the injection nozzle 5 and reduce the heat loss of the injection nozzle 5 during injection.

[0028] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
