Description

Technical Field

[0001] This utility model relates to the field of injection molding technology, specifically to a bushing injection molding device. Background Technology

[0002] Injection molding equipment is a key piece of equipment in the injection molding process. It is mainly used to process thermoplastic or thermosetting plastics into plastic products of various shapes. The screw in the injection molding equipment rotates in the barrel, conveying, compressing and shearing the plastic granules added to the hopper. At the same time, the heating device outside the barrel heats the plastic, making the plastic gradually soften and reach a molten state, thus achieving uniform plasticization.

[0003] Bushing injection molding equipment is used to process thermoplastic plastics into bushing-type plastic products. Its working process involves heating and melting granular plastic raw materials using an injection molding machine, and then injecting the molten plastic into a mold cavity of a specific shape under high pressure. After cooling and solidification, the mold is opened and the formed bushing product is taken out. However, bushing injection molding equipment often lacks the function of automatic material handling and bushing classification, requiring manual material handling and classification, which is time-consuming and inefficient.

[0004] In view of this, we propose a bushing injection molding device. Utility Model Content

[0005] The purpose of this invention is to provide a bushing injection molding device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0009] An asynchronous motor is fixedly installed on one side wall of the hydraulic device. A rotating rod is rotatably installed inside the hydraulic device through bearing components. The output end of the asynchronous motor is fixedly connected to one end of the rotating rod, and a connecting plate is fixedly installed on the other end of the rotating rod.

[0010] An inclined plate is fixedly installed on the upper surface of the bottom of the base, and baffles are fixedly installed at both ends of the inclined plate. A stacking plate is fixedly installed at the bottom of the inclined plate.

[0011] In a further embodiment, the slide rails are provided in multiple sets.

[0012] In a further embodiment, the inclined plate, baffle, and stacking plate are provided in two sets, and the two sets of inclined plates, baffles, and stacking plates are mirror images of each other at both ends of the base, with the vertical center line of the connecting plate as the mirror axis.

[0013] In a further embodiment, the receiving plate is located directly below the fixed template, thereby improving material receiving efficiency.

[0014] In a further embodiment, the stacking plate is provided with an auxiliary component, which includes a slide rail. The slide rail is fixedly installed at both ends of the stacking plate. A slide rod is slidably installed inside the slide rail. A spring is fixedly installed at the bottom end of the slide rod, and a telescopic rod is fixedly installed at the other end of the spring.

[0017] Compared with the prior art, the present invention provides a bushing injection molding device, which has the following advantages:

[0018] 1. This bushing injection molding device, in order to classify bushings after injection molding from different batches, is equipped with a molding assembly. First, it works with the moving mold plate, slide rail, fixed mold plate, and molding part to form the bushing. After forming, the asynchronous motor is started, and with the help of the rotating rod, receiving plate, inclined plate, baffle, and stacking plate, the receiving plate is tilted to the left and right at a certain angle, so that the bushing enters different stacking plates, thereby classifying the bushing. The classification efficiency after injection molding is higher, eliminating the need for manual classification, saving time and effort.

[0019] 2. In order to prevent the bushings from accumulating at the stacking plate and affecting subsequent material feeding, this bushing injection device is equipped with auxiliary components. When the operator presses the horizontal bar, in conjunction with the slide rail, slide rod, spring, telescopic rod, horizontal bar, and connecting rod, the pressure plate is pressed down and moved by the slide rail, thereby scraping the accumulated bushings to the back of the stacking plate, making space on the stacking plate, preventing the accumulated bushings from affecting subsequent material feeding, and thus improving the feeding efficiency.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

Furthermore, the term "above" may also be used in certain circumstances to indicate a dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application according to the specific circumstances.

[0031] Please see Figures 1-5 This utility model provides a technical solution:

[0032] A bushing injection molding device includes a base 1, an injection molded part 2 fixedly mounted on the top of the base 1, an inlet pipe 3 fixedly mounted on the top of the injection molded part 2, a feeding pipe 4 fixedly mounted on one end of the side wall of the injection molded part 2, an injection head 5 fixedly mounted on the other end of the feeding pipe 4, and a hydraulic device 6 fixedly mounted on the top of the base 1.

[0033] In one embodiment of this utility model, a molding assembly 7 is provided on the base 1. The molding assembly 7 includes a movable template 71. One end of the movable template 71 is fixedly installed on the piston end of the hydraulic device 6. One end of the slide rail 72 is fixedly installed on the side wall of the hydraulic device 6. The movable template 71 is slidably installed outside the slide rail 72. A fixed template 73 is fixedly installed on the other end of the slide rail 72. The injection head 5 is internally connected to the fixed template 73. A molding part 74 is provided on the top of the base 1. The fixed template 73 is fixedly connected to the side wall of the molding part 74. An asynchronous motor 75 is fixedly installed on the side wall of one end of the hydraulic device 6. The hydraulic device 6 is internally connected to a shaft. The support is rotatably mounted with a rotating rod 76. The output end of the asynchronous motor 75 is fixedly connected to one end of the rotating rod 76. The other end of the rotating rod 76 is fixedly mounted with a connecting plate 77. The bottom upper surface of the base 1 is fixedly mounted with an inclined plate 78. Both ends of the inclined plate 78 are fixedly mounted with baffles 79. The bottom of the inclined plate 78 is fixedly mounted with a stacking plate 710. The slide 72 is provided with multiple sets. There are two sets of inclined plates 78, baffles 79 and stacking plates 710. The two sets of inclined plates 78, baffles 79 and stacking plates 710 are mirror images of each other with the vertical center line of the connecting plate 77 as the mirror axis. The connecting plate 77 is located directly below the fixed template 73.

[0034] In this embodiment, during injection molding, plastic material is added to the feed pipe 3 and enters the injection head 5 through the feed pipe 4. When the injection material is ready, the hydraulic pump of the hydraulic device 6 starts working, pressurizing the hydraulic oil and delivering it to the hydraulic cylinder. Under the pressure of the hydraulic oil, the piston pushes the moving platen 71 to slide along the slide rail 72 towards the fixed platen 73. After the moving platen 71 and the fixed platen 73 close, they form the bushing molding cavity. The injection head 5 injects the high-temperature and high-pressure molten plastic into the molding cavity through the gating system. The plastic cools and solidifies in the mold cavity, completing the injection molding of the bushing. After the bushing injection molding is completed, the hydraulic device 6 reverses its operation, the hydraulic oil flows back, and the piston drives the moving platen 71 to return to its initial position along the slide rail 72, opening... The molding cavity allows the molded bushing to fall out. At this time, the asynchronous motor 75 is started, and the rotating rod 76 drives the receiving plate 77 to rotate, so that the receiving plate 77 is tilted and aligned with the inclined plate 78 at one end. The molded bushing falls naturally from the fixed template 73 onto the surface of the receiving plate 77. Because the receiving plate 77 is tilted, the bushing slides along the receiving plate 77 under the action of gravity and falls onto the inclined plate 78 until it reaches the stacking plate 710. When different batches of bushings need to be classified, the asynchronous motor 75 drives the receiving plate 77 to rotate to the other inclined plate 78, and the above process is repeated, thereby realizing the classification of different batches of injection-molded bushings. This makes the classification of bushings after injection molding more efficient, saves the manual classification process, and saves time and effort.

[0035] In one embodiment of this utility model, an auxiliary component 8 is provided on the stacking plate 710. The auxiliary component 8 includes a slide rail 81. The slide rail 81 is fixedly installed at both ends of the stacking plate 710. A slide rod 82 is slidably installed inside the slide rail 81. One end of a spring 83 is fixedly installed at the bottom of the slide rod 82. A telescopic rod 84 is fixedly installed at the other end of the spring 83. The telescopic rod 84 is sleeved inside the slide rod 82. A crossbar 85 is fixedly installed at the top of the telescopic rod 84. One end of a connecting rod 86 is fixedly installed at the bottom of the crossbar 85. A pressure plate 87 is fixedly installed at the other end of the connecting rod 86. Two sets of slide rail 81, slide rod 82, spring 83, telescopic rod 84 and connecting rod 86 are provided.

[0036] In this embodiment, the bushings will accumulate on the stacking plate 710. When the bushings accumulate to a certain extent on the stacking plate 710, it will affect subsequent material feeding. The operator manually presses the crossbar 85. Pressing the crossbar 85 will cause the telescopic rod 84 to overcome the elastic force of the spring 83 and retract into the slide rod 82. At the same time as the crossbar 85 is pressed down, the connecting rod 86 will move downward with the crossbar 85. The downward movement of the connecting rod 86 will drive the pressure plate 87 to move downward until the pressure plate 87 contacts the accumulated bushings. The operator pushes the crossbar 85, and the movement of the crossbar 85 will drive the slide rod 82 within the slide rail 81. The sliding rod 82 slides, causing the connected telescopic rod 84, crossbar 85, connecting rod 86, and pressure plate 87 to move as a whole. During the movement, the pressure plate 87 scrapes the accumulated bushings, pushing them behind the stacking plate 710, thus freeing up space on the stacking plate 710. After the bushings are scraped to the appropriate position, the pressure plate 87 is moved back to the initial position to wait for the next operation, ensuring that subsequent bushings can be discharged normally, thus preventing the accumulated bushings from affecting subsequent discharge and improving discharge efficiency. The discharged bushings eventually fall into the subsequent collection container, which will not be described in detail here.

[0037] All electrical components mentioned in this application are electrically connected to the controller and 220V AC mains power. The controller is a conventional and known device that can control the injection molded part 2, the feeding tube 4, the injection head 5, the hydraulic device 6, and the asynchronous motor 75. All standard parts used in this application can be purchased from the market. The specific connection methods of each part are all conventional methods such as riveting and welding that are mature in the prior art. The machinery, parts, and equipment are all conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, and will not be described in detail here.

[0038] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
