Description

Technical Field

[0001] This application relates to the field of injection molding machines, and more particularly to a high-efficiency horizontal injection molding machine. Background Technology

[0002] Currently, injection molding machines are the most commonly used method for processing and molding the plastic casings of household appliances.

[0003] Currently, injection molding machines used for processing workpieces made from two different materials in a single molding process include... Figure 1 As shown, the system includes an injection cylinder 2 and a first feeding device 3 located at one end of the injection cylinder 2 for inputting material into the injection cylinder 2. The injection cylinder 2 includes a cylinder body 21, a fixed mold 22 fixed to one end of the cylinder body 21, and a movable mold 23 slidably connected within the cylinder body 21. The space within the cylinder body 21 between the fixed mold 22 and the movable mold 23 is called the injection space 24. A linear drive device 5 is provided at the end of the cylinder body 21 away from the feeding device for driving the movable mold 23 to slide. A first feed port 25 communicating with the first feeding device 3 is provided on opposite sides of the fixed mold 22. A second feed port 26 is provided on the side wall of the cylinder body 21. A second feeding device 4 is also provided for conveying material to the second feed port 26. In use, the position of the movable mold 23 is first adjusted by the linear drive device 5 so that a first forming space 241 for material embedding is formed between the movable mold 23 and the fixed mold 22, and the second feed port 26 is located on the side of the movable mold 23 away from the first forming space 241. The first material is injected into the first forming space 241 through the first feeding device 3, and waits for the material to cool and solidify. After the material in the first forming space 241 solidifies, the moving mold 23 is driven by the linear drive device 5 to slide away from the fixed mold 22 in the cylinder 21, so that the moving mold 23 and the first forming space 241 form a second forming space 242, and the second feeding port 26 is connected to the second forming space 242. Then, the second material is injected into the second forming space 242 through the second feeding device 4 from the second feeding port 26. After the material in the second forming space 242 solidifies, the materials in the first forming space 241 and the second forming space 242 will solidify into a whole, thereby obtaining a workpiece formed by the two materials in one piece.

[0004] However, when manufacturing the same workpiece, the material in the first forming space needs to solidify before being injected into the second forming space, and then the material in the second forming space needs to solidify again. This entire process takes a long time, resulting in low injection molding efficiency. Currently, in order to improve injection molding efficiency, the measures taken in this field are to improve the cooling efficiency of the material to reduce the cooling time and thus improve injection molding efficiency, but the effect is limited. Summary of the Invention

[0005] In order to shorten the overall cooling time of the material and improve the injection molding efficiency, this application provides a high-efficiency horizontal injection molding machine.

[0006] The high-efficiency horizontal injection molding machine provided in this application adopts the following technical solution: A high-efficiency horizontal injection molding machine, comprising: Control panel An injection molding cylinder, installed on the operating table, includes a cylinder body, a fixed mold fixed to one end of the cylinder body, and a movable mold slidably connected to the cylinder body. An injection space is formed between the fixed mold and the movable mold. A first feed port is provided on the fixed mold, and a second feed port is provided on the side wall of the cylinder body. The first feeding device is installed on the operating table, located on one side of the cylinder, and communicates with the first feeding port, for conveying materials through the first feeding port to the injection space; The second feeding device is installed on the operating table, located on one side of the cylinder, and communicates with the second feeding port, for conveying materials through the second feeding port to the injection space; An isolation plate is slidably connected within the injection molding space, and the cylinder has an installation groove for inserting the isolation plate into the injection molding space; The space between the partition plate and the fixed mold within the injection molding space is called the first forming space, the space between the partition plate and the moving mold is called the second forming space, and the space for the partition plate to be inserted is called the third space; the first feed port is connected to the first forming space, the second feed port is connected to the second forming space, a third feed port connected to the third space is provided on the side wall of the cylinder, and the second feeding device is connected to the third feed port.

[0007] By adopting the above technical solution, during use, due to the setting of the isolation plate, two materials can be injected into the first and second forming spaces respectively through the first and second feed ports. The isolation plate can separate the materials in the first and second forming spaces, preventing the two materials from mixing, allowing the materials in the first and second forming spaces to cool and solidify simultaneously. Then, after the materials in the first and second forming spaces have solidified, the isolation plate is removed from the third space, and the material is injected into the third space through the third feed port. This allows the material in the third space to connect the objects in the first and second forming spaces together, forming a whole, and then wait for the material in the third space to solidify. Because there is less material in the third space, the second solidification time is greatly shortened, thereby reducing the overall forming time, reducing the overall cooling time of the material, and improving injection molding efficiency.

[0008] Optionally, the second feeding device includes a feeding cylinder installed on the operating table, a spiral blade rotatably connected inside the feeding cylinder, a drive motor for driving the spiral blade to rotate, and a material bucket installed on the operating table. The material bucket outlet is connected to the inside of the feeding cylinder. A third feeding pipe is fixedly connected between one end of the feeding cylinder and the third feeding port. A second feeding pipe for conveying the material in the material bucket to the second feeding port is fixedly connected between the side wall of the feeding cylinder and the second feeding port.

[0009] By adopting the above technical solution, the material reaches the feeding cylinder from the material barrel, and then the drive motor can drive the spiral blades to rotate, which can push the material to the second feeding port and the third feeding port, so as to inject the material into the injection space through the second feeding port and the third feeding port.

[0010] Optionally, the isolation plate is provided with a clamping device for fixing the position of the isolation plate in the injection space on the side facing the mounting groove, and a driving device for driving the isolation plate to slide out of the injection space.

[0011] By adopting the above technical solution, when the partition plate is installed in the third space, the clamping device can fix the position of the partition plate in the third space, preventing the partition plate from sliding out of the third space and causing the materials in the first forming space and the second forming space to mix. After the materials in the first forming space and the second forming space solidify, the partition plate can be pulled out of the injection space by the driving device, making it easier to inject the material into the third space through the third feed port.

[0012] Optionally, the clamping device includes an auxiliary rod fixed to the side of the isolation plate facing the mounting groove, a clamping cylinder slidably sleeved on the auxiliary rod, a driving plate mounted on the auxiliary rod, and a clamping spring sleeved on the auxiliary rod. The clamping cylinder is closed at one end and its open end is detachably connected to the cylinder body. The driving plate and the clamping spring are both located inside the clamping cylinder. The two ends of the clamping spring abut against the closed ends of the driving plate and the clamping cylinder, respectively. Under the elastic force of the clamping spring, the isolation plate is located within the injection molding space.

[0013] By adopting the above technical solution, when the isolation plate is installed in the third space, the clamping cylinder is directly installed on the cylinder body. At this time, the clamping spring will abut against the driving plate, thereby giving the clamping plate a force towards the third space through the driving plate, so that the isolation plate is firmly abutted against the inner wall of the injection space away from the installation groove, thereby fixing the position of the isolation plate in the injection space.

[0014] Optionally, a fixing plate is fixedly connected to the side wall of the pressing cylinder, and an installation block is fixedly connected to the side wall of the cylinder. The installation block has a sliding groove for the fixing plate to slide into, and a limiting groove communicating with the sliding groove is provided on the side wall of the sliding groove. The fixing plate can slide from the sliding groove to the limiting groove.

[0015] By adopting the above technical solution, when in use, the fixing plate is directly slid into the sliding groove, and then the clamping cylinder is selected to make the fixing plate slide into the limiting groove, which can fix the position of the clamping cylinder on the cylinder body, prevent the clamping cylinder from separating from the cylinder body, and thus make the clamping spring fix the isolation plate.

[0016] Optionally, a drive gear is rotatably connected to the side wall of the cylinder, a driven gear that meshes with the drive gear is fixedly connected to the clamping cylinder, and a drive motor that drives the drive gear to rotate is fixedly connected to the cylinder.

[0017] By adopting the above technical solution, the motor can be started by operation, and the driven gear can be driven to rotate through the active gear, which in turn drives the clamping cylinder to rotate, so that the fixed plate can be automatically rotated from the sliding groove to the limiting groove, or the fixed plate can be rotated from the limiting groove to the sliding groove.

[0018] Optionally, the thickness of the driven gear gradually increases from the end away from the cylinder to the end closer to the cylinder, and the thickness of the driving gear gradually increases from the end closer to the cylinder to the end away from the cylinder.

[0019] By adopting the above technical solution, when the driving device drives the clamping cylinder to lift and lower to slide the isolation plate to the third space or pull the isolation plate out of the third space, the clamping cylinder can smoothly drive the driven gear to separate from the driving gear or drive the driven gear to mesh with the driving gear.

[0020] Optionally, the driving device includes a linear drive fixed to the operating table and a connector connecting the linear drive and the clamping cylinder. A limit plate is installed on the auxiliary rod, and the limit plate is located on the side of the clamping cylinder away from the cylinder body.

[0021] By adopting the above technical solution, when the linear drive is started, the linear drive will drive the clamping cylinder to rise and fall through the connecting part. At this time, the clamping cylinder will slide on the auxiliary rod. When the clamping cylinder slides to abut against the limit plate, it will drive the auxiliary plate to rise and fall synchronously through the limit plate, thereby driving the isolation plate fixed to the auxiliary rod to rise and fall, so as to realize the automatic sliding of the isolation plate into the third space or the sliding of the isolation plate out of the third space.

[0022] Optionally, the connector includes a connecting rod fixed between the linear drive and the clamping cylinder, and a connecting ball fixed to one end of the connecting rod facing the clamping cylinder. The closed end of the clamping cylinder has a fixing groove for the connecting ball to be inserted and slid.

[0023] By adopting the above technical solution, the connection between the connecting rod and the clamping cylinder is achieved through the cooperation of the connecting ball and the fixed groove, allowing the linear drive component to smoothly drive the clamping cylinder to rise and fall via the connecting rod. When the drive motor rotates the clamping cylinder to achieve the fixed separation of the clamping cylinder from the cylinder body, the connecting ball also slides within the fixed groove, ensuring the connection between the linear drive component and the clamping cylinder.

[0024] Optionally, the linear drive is a drive cylinder, and the drive cylinder is equipped with a linear displacement sensor for detecting the extension and retraction of the piston rod of the drive cylinder. The drive cylinder is configured to stop when the data detected by the linear displacement sensor reaches a set value.

[0025] By adopting the above technical solution, the extension and retraction of the piston rod of the cylinder can be detected by the linear displacement sensor, ensuring that the isolation plate can be smoothly installed into the third space. When the isolation plate is slid out of the third space, the isolation plate is also located in the installation groove, thereby sealing the installation groove and preventing the material in the third space from being moved out of the installation groove due to the isolation plate sliding out of the installation groove.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. This application, by setting a partition plate between the first forming space and the second forming space, allows two materials to be injected into the first forming space and the second forming space simultaneously, enabling the materials in the first forming space and the materials in the second forming space to solidify and form at the same time without increasing the waiting time excessively. After the materials in the first forming space and the second forming space have solidified and formed, the partition plate is removed, and the material is injected into the forming space. Because the forming space is small, the solidification time of the material in the forming space is also short. Compared with the existing method that requires one material to solidify and form before waiting for the second material to solidify and form, and because there are many of both materials, the required forming time is long, this solution greatly shortens the solidification and forming time and improves injection molding efficiency. 2. By setting up a clamping device and a driving device, this application enables the clamping device to fix the position of the isolation plate in the third space when the isolation plate is installed in the third space, making the isolation plate more secure; and when it is necessary to slide the isolation plate out of the third space or reinstall the isolation plate in the third space, the driving device can drive the isolation plate to move automatically. 3. The connection between the ball and the fixed groove allows the cylinder to move the pressing cylinder vertically up and down while simultaneously rotating it relative to the cylinder, ensuring the connection between the pressing cylinder and the cylinder body.

[0034] The following is in conjunction with the appendix Figure 2-6 This application will be described in further detail.

[0035] This application discloses a high-efficiency horizontal injection molding machine. (Refer to...) Figure 2The high-efficiency horizontal injection molding machine includes an operating table 1, an injection cylinder 2 installed on the operating table 1, a first feeding device 3 for conveying one type of material to the injection cylinder 2, and a second feeding device 4 for conveying another type of material to the injection cylinder 2.

[0036] Reference Figure 2 and Figure 3 The injection molding cylinder 2 includes a cylinder body 21 mounted on an operating table 1, a fixed mold 22 fixedly connected within the cylinder body 21, and a movable mold 23 slidably connected within the cylinder body 21. An injection space 24 for material injection molding is formed within the cylinder body 21 between the fixed mold 22 and the movable mold 23. A first feed port 25 is provided on opposite sides of the fixed mold 22. A first feeding device 3 communicates with the first feed port 25 and is used to inject one type of material into the injection space 24 through the first feed port 25. A second feed port 26 is provided on the side wall of the cylinder body 21. A second feeding device 4 communicates with the second feed port 26 and is used to inject another type of material into the injection space 24 through the second feed port 26. Meanwhile, a linear drive device 5 is also provided on the operating table 1 to drive the moving mold 23 to move back and forth. The linear drive device 5 can be an injection cylinder 51. The cylinder body of the injection cylinder 51 is fixedly connected to the operating table 1, and the piston rod of the injection cylinder 51 extends into the cylinder 21 and is fixedly connected to the moving mold 23.

[0037] Meanwhile, a mounting groove 28 is provided on one side of the cylinder 21, and a partition plate 6 is slidably connected in the mounting groove 28. The first feed port 25 and the second feed port 26 are located on both sides of the partition plate 6, respectively. Under normal conditions, the partition plate 6 is located in the injection space 24, thus dividing the injection space 24 into two parts. The part of the injection space 24 located between the partition plate 6 and the fixed mold 22 is called the first forming space 241, and the part located between the partition plate 6 and the moving mold 23 is called the second forming space 242. The part used to install the partition plate 6 is called the third space 243. A third feed port 27 communicating with the third space 243 is provided on the side wall of the cylinder 21. The third feed port 27 and the mounting groove 28 are located on different sides of the cylinder 21, and the second feeding device 4 is connected to the third feed port 27. In use, one material is directly injected into the first molding space 241 through the first feed port 25 via the first feeding device 3, while another material is injected into the second molding space 242 through the second feed port 26 via the second feeding device 4. This allows both materials to be injected into the injection space 24 simultaneously, while the partition plate 6 isolates the two materials to prevent them from mixing. At this time, the material in the first molding space 241 can cool and solidify simultaneously with the material in the second molding space 242, without having to wait for one material to solidify before injecting and waiting for the second material to solidify. This significantly shortens the total cooling time for both materials. After the materials in the first forming space 241 and the second forming space 242 have solidified, the partition plate 6 is slid in the mounting groove 28 so that the partition plate 6 slides out of the third space 243. The second feeding device 4 injects the material into the third space 243 through the third feeding port 27. Since the third space 243 is smaller, the material in the third space 243 cools faster than the material in the first forming space 241 or the second forming space 242, and the cooling time is shorter, resulting in higher overall injection molding efficiency.

[0038] To prevent the partition plate 6 from being located in the third space 243, when materials are injected into the first injection space 24 and the second injection space 24, the materials will cause the partition plate 6 to move within the third space 243, resulting in the mixing of the materials in the first injection space 24 and the second injection space 24. A clamping device 7 for fixing the position of the partition plate 6 within the third space 243 and a driving device 8 for driving the partition plate 6 to slide within the third space 243 are also provided between the cylinder 21 and the partition plate 6. The driving device 8 can automatically install the partition plate 6 into or slide it out of the third space 243. When the partition plate 6 is installed into the third space 243, the clamping device 7 can fix the position of the partition plate 6 within the third space 243, reducing the probability of the partition plate 6 sliding within the third space 243.

[0039] Reference Figure 4 and Figure 5The clamping device 7 includes an auxiliary rod 71 fixed to the side of the isolation plate 6 facing the mounting groove 28 and a clamping cylinder 72 sleeved on the auxiliary rod 71. The end of the auxiliary rod 71 away from the isolation plate 6 extends outside the cylinder 21. The clamping cylinder 72 is located outside the cylinder 21 and is closed at one end. The open end of the clamping cylinder 72 faces the cylinder 21 and is detachably connected to the cylinder 21. A driving plate 73 is also installed on the auxiliary rod 71. A clamping spring 74 is sleeved on the auxiliary rod 71. The clamping spring 74 is located inside the clamping cylinder 72 and its two ends abut against the driving plate 73 and the closed end of the clamping cylinder 72, respectively. Under normal conditions, the clamping cylinder 72 is installed on the cylinder body 21, and the clamping spring 74 abuts against the driving plate 73 under its own elastic force, thereby pushing the driving plate 73 closer to the direction of the cylinder body 21. Then, through the auxiliary rod 71, the isolation plate 6 is moved towards the direction of the third space 243, so that the side of the isolation plate 6 away from the auxiliary rod 71 is firmly abutted against the inner wall of the cylinder body 21 away from the placement groove, thereby fixing the position of the isolation plate 6 in the third space 243.

[0040] Reference Figure 5 and Figure 6 A fixing plate 721 is fixedly attached to the opposite side walls of the clamping cylinder 72. Two mounting blocks 75 are fixedly attached to the outer wall of the cylinder 21 on one side where the mounting groove 28 is opened. The two mounting blocks 75 are located on both sides of the mounting groove 28, and each mounting block 75 is arc-shaped and surrounds the outer wall of the clamping cylinder 72. Each mounting block 75 has a sliding groove 751 for the fixing plate 721 to slide into. A limiting groove 752 communicating with the sliding groove 751 is opened on the side wall of the sliding groove 751. When it is necessary to fix the position of the clamping cylinder 72 on the cylinder 21, the fixing plate 721 is directly slid into the sliding groove 751, and then the clamping cylinder 72 is rotated so that the fixing plate 721 slides into the limiting groove 752, thus fixing the position of the clamping cylinder 72 on the cylinder 21. When it is necessary to release the fixed relationship between the clamping cylinder 72 and the cylinder body 21, simply rotate the clamping cylinder 72 in the opposite direction so that the fixing plate 721 slides from the limiting groove 752 into the sliding groove 751. Then move the clamping cylinder 72 away from the cylinder body 21 to slide the fixing plate 721 out of the sliding groove 751 and release the connection between the clamping cylinder 72 and the cylinder body 21.

[0041] Reference Figure 2 and Figure 5The driving device 8 includes a linear drive 81 fixed to the operating table 1 and a connecting member 82 installed between the linear drive 81 and the clamping cylinder 72. The linear drive 81 can be a drive cylinder 811. The connecting member 82 includes a connecting rod 821 and a connecting ball 822 connecting the piston rod of the drive cylinder 811 and the clamping cylinder 72. One end of the connecting ball 822 is connected to the end of the connecting rod 821 away from the drive cylinder 811, and the other end is connected to the clamping cylinder 72. At the same time, a fixing groove 722 is provided at the closed end of the clamping cylinder 72 for the connecting ball 822 to be inserted and slide. This allows the connecting ball 822 to slide within the fixing groove 722 when the clamping cylinder 72 is rotated to release the connection between the clamping cylinder 72 and the cylinder body 21.

[0042] Meanwhile, a limiting plate 76 is installed on the auxiliary rod 71. The limiting plate 76 is located on the side of the pressing cylinder 72 away from the cylinder body 21. When the linear drive 81 drives the pressing cylinder 72 to move away from the cylinder body 21, the pressing cylinder 72 will slide on the auxiliary rod 71 until the closed end of the pressing cylinder 72 abuts against the limiting plate 76. This will drive the limiting plate 76 to move away from the cylinder body 21 together with the pressing cylinder 72. The limiting plate 76 will drive the isolation plate 6 to move through the auxiliary rod 71, so that the isolation plate 6 slides out from the third space 243.

[0043] Understandably, when the isolation plate 6 slides out of the third space 243, when the end of the isolation plate 6 away from the auxiliary rod 71 slides out of the third space 243 and reaches the installation groove 28, the isolation plate 6 is controlled to stop, so that the isolation plate 6 can not affect the injection of materials into the third space 243, while also sealing the installation groove 28 to prevent the materials injected into the third space 243 from overflowing from the installation groove 28.

[0044] Therefore, a linear displacement sensor 812 is fixedly connected to the driving cylinder 811. The body of the linear displacement sensor 812 is fixedly connected to the cylinder body of the driving cylinder 811, and the sliding plate of the linear displacement sensor 812 is fixedly connected to the piston rod of the driving cylinder 811. The extension and retraction of the piston rod of the driving cylinder 811 can be detected by the linear displacement sensor 812.

[0045] The cylinder 811 is configured to stop when the data detected by the linear displacement sensor 812 reaches a set value. Specifically, both the linear displacement sensor 812 and the cylinder 811 are connected to a PLC controller. The linear displacement sensor 812 is used to detect the extension and retraction of the piston rod of the cylinder 811 in real time and transmits the detection data to the PLC controller in real time. When the PLC controller receives the data detected by the linear displacement sensor 812 and it reaches the set value, it outputs a stop signal, and the cylinder 811 stops upon receiving the stop signal. This achieves control over the extension and retraction of the isolation plate 6.

[0046] Reference Figure 2The cylinder 21 is also equipped with a drive motor 211 that automatically selects and connects the clamping cylinder 72 to the cylinder 21. Specifically, the drive motor 211 is vertically arranged, and a drive gear 212 is fixedly connected to the output shaft of the drive motor 211. A driven gear 213 that meshes with the drive gear 212 is fixedly connected to the clamping cylinder 72. When the drive motor 211 is started, it will drive the driven gear 213 to rotate through the drive gear 212, thereby driving the clamping cylinder 72, which is fixedly connected to the driven gear 213, to rotate. This will cause the fixed plate 721 to slide from the sliding groove 751 to the limiting groove 752, or vice versa.

[0047] Reference Figure 6 The tooth width of the driven gear 213 gradually increases from the end near the cylinder 21 to the end away from the cylinder 21, while the tooth width of the driving gear 212 gradually decreases from the end near the cylinder 21 to the end away from the cylinder 21. This makes the gap between the two teeth of the driving gear 212 gradually increase from the end near the cylinder 21 to the end away from the cylinder 21. This allows the teeth of the driven gear 213 to slide smoothly between the two teeth of the driving gear 212 when the driven gear 213 slides from the side away from the cylinder 21 toward the direction of the cylinder 21, thus achieving smooth meshing between the driven gear 213 and the driving gear 212.

[0048] It is understandable that both the driving gear 212 and the driven gear 213 are involute gears to ensure smooth meshing (the shapes in the figure are for illustrative purposes only). Alternatively, the driving gear 212 and driven gear 213 could be ordinary spur gears, with each tooth of the driven gear 213 having a chamfer at the end facing the cylinder 21. This reduces the width of the driven gear 213 at the cylinder 21, facilitating its smooth sliding between the two teeth of the driving gear 212. Conversely, the end of the driving gear 212 away from the cylinder 21 also has a chamfer, widening the distance between the two teeth of the driving gear 212 on the side away from the cylinder 21, further facilitating the smooth sliding of the teeth of the driven gear 213 between the two teeth of the driving gear 212.

[0049] Meanwhile, an encoder is also fixedly connected to the output shaft of the drive motor 211. Both the encoder and the drive motor 211 are connected to the PLC controller. The encoder is used to detect the rotation of the output shaft of the drive motor 211 in real time and transmit the detection data to the PLC controller in real time. When the PLC controller receives the data detected by the encoder and the value reaches the set value, it will control the drive motor 211 to stop, thereby controlling the drive motor 211 to rotate the set angle.

[0050] In use, the cylinder 811 is directly started, which slides the drive plate 73 into the third space 243. After the piston rod of the drive cylinder 811 moves a set length, the PLC controller stops the drive cylinder 811. The driven gear 213 also slides smoothly to mesh with the drive gear 212, and the fixed plate 721 slides into the sliding groove 751. At this time, the drive motor 211 starts and drives the drive gear 212 to rotate a set angle, which drives the fixed plate 721 to slide into the limit groove 752, completing the automatic installation of the isolation plate 6. At this time, the isolation plate 6 is also firmly abutted against the inner wall of the cylinder 21 under the elastic force of the compression spring 74, making the installation and fixation of the isolation plate 6 more secure.

[0051] Reference Figure 5 Both the driving plate 73 and the limiting plate 76 are threadedly connected to the auxiliary rod 71, allowing the positions of the driving plate 73 and the limiting plate 76 on the auxiliary rod 71 to be adjusted as needed. This facilitates installation and also allows for adjustment of the position of the clamping cylinder 72 relative to the auxiliary rod 71, thus adjusting the clamping force after the driving plate 73 is installed. It also accommodates the installation needs of cylinders 21 of different heights.

[0052] After the isolation plate 6 is installed, the first feeding device 3 is started to feed material into the first feeding port 25, and the second feeding device 4 is started to feed material into the second feeding port 26, so that the two materials are injected into the first injection space 24 and the second injection space 24 respectively, so that the two materials can cool and solidify at the same time.

[0053] The first feeding device 3 and the second feeding device 4 have the same structure, the only difference being the installation position and the position of the discharge port. This application will use the second feeding device 4 as an example for explanation.

[0054] Reference Figure 2 and Figure 3The second feeding device 4 includes a feeding cylinder 41 mounted on the operating table 1, a spiral blade 42 rotatably connected inside the feeding cylinder 41, a drive motor 43 driving the spiral blade 42 to rotate, and a material bucket 44 mounted on the operating table 1. The drive motor 43 is fixedly connected to the end of the feeding cylinder 41 away from the cylinder body 21, and the output shaft of the drive motor 43 passes through the feeding cylinder 41 and is fixedly connected to the spiral blade 42 located inside the feeding cylinder 41. The material bucket 44 is placed vertically, with the upper opening as the feeding port and the lower opening as the discharging port. The discharging port of the material bucket 44 communicates with the interior of the feeding cylinder 41 and is located at the end of the feeding cylinder 41 near the drive motor 43. A third feeding pipe 452 connects the end of the feeding cylinder 41 away from the drive motor 43 and the third feeding port 27, and the feeding cylinder 41 communicates with the third feeding port 27 through the third feeding pipe 452. A second feed pipe 451 is fixedly connected to the side wall of the feed cylinder 41 near the third feed pipe 452. The second feed pipe 451 communicates with the inside of the feed cylinder 41, and the end of the second feed pipe 451 away from the feed cylinder 41 is connected to the cylinder body 21 and communicates with the second feed port 26. By starting the drive motor 43, the material can be conveyed to the second feed pipe 451 and the third feed pipe 452 through the spiral blades 42, thereby realizing the injection of material into the second injection space 24 through the second feed port 26 or the injection of material into the third space 243 through the third feed port 27.

[0055] To ensure that material can only be injected into either the second inlet 26 or the third inlet 27 at a time, a second control valve 453 is installed on the second inlet pipe 451 to control its opening and closing, and a third control valve 454 is installed on the third inlet pipe 452 to control its opening and closing. When material needs to be injected into the second injection space 24 through the second inlet 26, the second control valve 453 is opened and the third control valve 454 is closed directly; when material needs to be injected into the third space 243 through the third inlet 27, the third control valve 454 is opened and the second control valve 453 is closed directly, making the operation more flexible.

[0056] It is understood that a discharge device is provided on the fixed mold 22 to control the workpiece to slide out of the cylinder 21 after injection molding. After the workpiece is injection molded, the moving mold 23 is directly driven by the injection cylinder 51 to slide out from the end of the cylinder 21 away from the fixed mold 22. Then the discharge device can push the workpiece away from the fixed mold 22, so that the workpiece falls from the end of the cylinder 21 away from the fixed mold 22, thus achieving discharge. The structure of the discharge device can be selected from existing methods such as cylinders, which will not be described in detail in this application.

[0057] The implementation principle of a high-efficiency horizontal injection molding machine according to this application embodiment is as follows: During use, the linear drive component 81 directly drives the clamping cylinder 72 downward, thereby installing the isolation plate 6 into the third space 243. Once the isolation plate 6 is in place, the PLC controller automatically stops the drive cylinder 811. When the drive cylinder 811 stops, the PLC controller also automatically starts the drive motor 211 and controls the output shaft of the drive motor 211 to rotate at a set angle, thereby automatically fixing the clamping cylinder 72. After the isolation plate 6 is installed, the clamping spring 74 also applies pressure to the isolation plate 6, making the installation of the isolation plate 6 more secure. Even after the isolation plate 6 wears down after a period of use, the elastic force of the clamping spring 74 can still ensure the secure installation of the isolation plate 6. Furthermore, by changing the clamping spring 74 with different elastic amounts, the force of the isolation plate 6 against the cylinder 21 after installation can be adjusted, making operation more flexible. Then, the first feeding device 3 and the second feeding device 4 automatically start, thereby realizing automatic feeding. During the feeding process of the second feeding device 4, the second control valve 453 can be controlled to open and the third control valve 454 can be controlled to close, so that the material can smoothly pass through the second feed port 26 and reach the second injection space 24. Until both the first injection space 24 and the second injection space 24 are filled with material, the isolation plate 6 isolates the two materials, so that the materials in the first injection space 24 and the materials in the second injection space 24 can cool and solidify simultaneously. After the materials in the first injection space 24 and the second injection space 24 have solidified, the PLC controller will control the drive motor 211 to rotate in the opposite direction by a set angle to release the connection between the clamping cylinder 72 and the cylinder 21. Then, the linear drive component 81 drives the clamping cylinder 72 to rise by a set length, thereby pulling the isolation plate 6 out from the third space 243 into the mounting slot 28. At this time, the second feeding device 4 is activated, and simultaneously the third control valve 454 opens and the second control valve 453 closes, allowing the second feeding device 4 to inject material into the third space 243 through the third feed port 27. Once the material in the third space 243 cools and solidifies, the workpiece in the injection molding space 24 is formed into a single unit. Because there is less material in the third space 243, the cooling time is also shorter, reducing the overall cooling time and significantly shortening the injection molding time, thus improving injection molding efficiency. The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
