Description

Technical Field

[0001] This invention belongs to the field of plastic masterbatch production technology, specifically relating to an injection molding machine for plastic masterbatch production and its usage method. Background Technology

[0002] Plastic masterbatch is a granular concentrate made by pre-dispersing an excessive amount of additives or fillers uniformly in a carrier resin. It is used to simplify the production process of plastic products. It allows plastic processing plants to eliminate the need to add various additives separately during production. They only need to mix the masterbatch in proportion, thereby improving efficiency and product quality.

[0003] After production, new batches of plastic masterbatch usually need to be sampled on a small injection molding machine. This step is a key quality control step to verify its color uniformity, dispersion effect and impact on product performance.

[0004] When using existing small injection molding machines, the barrel is mostly integrated, which means that after sampling the previous batch of masterbatch, some masterbatch may remain inside the barrel and on the screw surface. This masterbatch will affect the sampling operation of the next batch of masterbatch. To solve the above-mentioned problem, we propose an injection molding machine for plastic masterbatch production and its usage method. Summary of the Invention

The upper end of the base is fixedly connected to a telescopic rod, and the load-bearing member is fixedly connected to the telescopic end of the telescopic rod.

[0014] A method of using an injection molding machine for producing plastic masterbatch. S1. After completing the sampling of the previous batch of plastic masterbatch, when it is necessary to clean the barrel, first start the external motor to drive the lead screw to rotate. At this time, the position adjustment plate moves away from the plastic component, thereby driving the three-dimensional part to move. S2. When the three-dimensional part moves, the rolling rod will move inside the adjustment groove, and the rolling rod will pass through the limiting part, the releasing part and the return part in sequence. When the rolling rod moves inside the limiting part, the injection head will be moved out of the A insertion groove. When the rolling rod moves to the inside of the releasing part, the rolling rod will move downward under the limiting of the inner wall of the releasing part, thereby driving the snap-fit ​​mechanism to move downward. At this time, the snap-fit ​​part releases the snap-fit ​​on the extension part, so that the subsequent barrel will not continue to move with the movement of the three-dimensional part. When the rolling rod moves to the inside of the return part, the rolling rod will move upward under the limiting of the inner wall of the return part, thereby driving the snap-fit ​​mechanism to return to the original position. S3. The three-dimensional component continues to move under the drive of the position adjustment plate. After the screw disengages from the inside of the barrel, the position adjustment plate will contact the contact plate. The position adjustment plate continues to move and will then push the contact plate to move. When the contact plate moves, it will drive the C gear to rotate through the movement of the D rack, and through the transmission shaft, drive the B gear to rotate, which in turn drives the B rack, the horizontal moving plate and the C rack to move. When the C rack moves horizontally, it drives the A gear that meshes with it to rotate, which in turn drives the A rack to move upward. At this time, through the load-bearing component, the barrel and the injection head can move upward. S4. After the barrel moves to its highest point, the worker can remove the barrel. At this time, the worker can clean the inner wall of the barrel and the surface of the screw to completely remove the previous batch of plastic masterbatch. S5. After cleaning the inside of the barrel and the surface of the screw, place the injection head back into the U-shaped part and place the barrel on the load-bearing part. Then move the position adjustment plate in the opposite direction to complete the assembly. After assembly, start the drive structure to drive the screw to rotate and complete the dry injection operation.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. When cleaning the inside of the barrel and the surface of the screw, the position of the three-dimensional component can be adjusted by moving the assembly, thereby disassembling the barrel and screw to facilitate subsequent cleaning operations. When installation is required, simply place the barrel in the specified position and then reverse the movement of the assembly to assemble the barrel and screw. The assembly design facilitates the disassembly and cleaning of the barrel and screw, thus avoiding the residue of the previous batch of masterbatch, which could affect the sampling results.

[0016] 2. When installing the barrel and screw, the positions of the two can be positioned by the snap-fit ​​assembly, so that the two can maintain a stable connection during injection molding. Furthermore, when the barrel needs to be removed later, the barrel can be segmented by the snap-fit ​​assembly, which makes it easier for workers to remove it.

[0017] 3. After the injection head is removed, the material cylinder can be lifted by the lifting component to facilitate the subsequent removal of the material cylinder by the workers. Since the contact plate is set inside the moving groove, the lifting component can be driven by pushing the contact plate during the movement of the position adjustment plate, so that the material cylinder can be lifted. Therefore, the material cylinder can be quickly removed in actual use, which is convenient for subsequent cleaning. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1

[0021] Please see Figures 1-10 The present invention provides an injection molding machine for producing plastic masterbatch, including a main body component 1, a plastic component 2 for molding plastic masterbatch is provided at the upper end of the main body component 1, an injection component 3 for injecting plastic masterbatch into the plastic component 2 is provided above the main body component 1, and a moving component 6 for controlling the horizontal movement of the injection component 3 is provided at the upper end of the main body component 1, and the injection component 3 is located at the upper end of the moving component 6. The upper end of the main body component 1 is provided with a lifting component 5 for controlling the injection component 3 to move up and down, and the upper end of the main body component 1 is provided with a snap-fit ​​component 4 for positioning the injection component 3.

[0022] Specifically, when prototyping the produced plastic masterbatch, the plastic component 2 and injection component 3 can be installed first. Then, plastic masterbatch can be poured into the injection component 3 to perform the prototyping operation. When prototyping the next batch of masterbatch, the position of the injection component 3 needs to be adjusted by moving component 6 first. Then, the locking component 4 is released from the locking of the local structure of the injection component 3 to disassemble the injection component 3. During disassembly, the local structure of the injection component 3 can be lifted by lifting component 5 to facilitate its removal for cleaning. This allows for local cleaning of the injection component 3, thoroughly cleaning the previous batch of masterbatch and avoiding affecting the next prototyping operation.

[0023] In this embodiment, the main component 1 includes a base 11, a discharge groove 12 is provided on the surface of the base 11, a collection box 13 is provided inside the discharge groove 12, a moving groove 14 and two A mounting grooves 15 are provided at the upper end of the base 11, a storage groove 16 is provided in each of the two A mounting grooves 15, and a rotating hole 18 and two B mounting grooves 17 are provided at the side end of the base 11.

[0024] Specifically, in practical use, in order to facilitate the subsequent installation of the lifting component 5, an A mounting groove 15, a storage groove 16 and a B mounting groove 17 can be opened on the surface of the base 11. In order to facilitate the subsequent installation of the moving component 6, a moving groove 14 and a rotating hole 18 are opened on the surface of the base 11. In order to collect the products generated during the prototyping operation for subsequent processing, a discharge groove 12 can be opened on the base 11, and a collection box 13 is set in the discharge groove 12. The collection box 13 is set below the plastic component 2 to facilitate subsequent collection.

[0025] In this embodiment, the plastic component 2 includes a main board A 21, which is fixedly connected to the upper end of the base 11. A limiting plate 22 is provided above the base 11. A control structure 25 is fixedly connected to the surface of the main board A 21. The telescopic end of the control structure 25 passes through the surfaces of the main board A 21 and the limiting plate 22. A main template 23 is fixedly connected to the end of the telescopic end of the control structure 25. A secondary template 24 is provided above the base 11. Multiple sleeve rods are fixedly connected between the limiting plate 22 and the secondary template 24. The main template 23 is sleeved on the multiple sleeve rods. A main board B 27 is fixedly connected to the upper end of the base 11. An insertion groove A 29 is opened on the surface of the main board B 27. A feeding component 28 is fixedly connected inside the insertion groove A 29. Multiple positioning rods 26 are fixedly connected to the surface of the main board B 27. The multiple positioning rods 26 pass through the main board A 21, the limiting plate 22, the main template 23 and the secondary template 24 in sequence, and the multiple positioning rods 26 are detachably connected to the main board A 21.

[0026] Specifically, during the sampling operation, the masterbatch is injected between the main template 23 and the secondary template 24 through the injection component 3, thereby enabling plastic deformation. After plastic deformation, the coloring effect and other data of the masterbatch can be judged by the state of the masterbatch. In actual use, the A main plate 21 and B main plate 27 are used to stably set the limiting plate 22 and the secondary template 24. The main template 23 can move stably by sliding on the sleeve rod. With the push of the control structure 25, the main template 23 can maintain stable and controllable movement during plastic deformation. In order to ensure the overall stability, the positioning rod 26 passes through the A main plate 21, the limiting plate 22, the main template 23 and the secondary template 24, and can be fixed by the external bolt group, thereby ensuring the stable setting of the A main plate 21 and B main plate 27.

[0027] Furthermore, the purpose of injection molding sampling is that the coloring effect of the masterbatch under high temperature, high pressure, and shear force can only be fully demonstrated during the injection molding process. Potential problems, such as pigment migration, filler agglomeration, and thermal decomposition discoloration, cannot be detected by visual inspection or melt flow index testing alone.

[0028] The injection-molded samples can be directly observed for: 1. Whether the color is uniform and whether there is a color difference; 2. Whether the surface is smooth and whether there are "white spots" or "fish eyes"; 3. Whether the mechanical properties such as strength and toughness are affected. These are the core indicators for judging the quality of the masterbatch.

[0029] During prototyping, parameters such as injection temperature, pressure, and speed can be adjusted to test the stability of the masterbatch under different conditions, providing data support for mass production.

[0030] In this embodiment, the injection assembly 3 includes a three-dimensional mechanism 34, which includes a three-dimensional component 341. The three-dimensional component 341 is fixedly connected to the upper end of the position adjustment plate 62. A driving structure 36 is fixedly connected to the surface of the three-dimensional component 341, and the output end of the driving structure 36 passes through the three-dimensional component 341. A screw 35 is fixedly connected to the output end of the driving structure 36. The surface of the three-dimensional component 341 is provided with a B insertion groove 342, an A extension groove 343, and a rectangular groove 344. A material cylinder 31 is provided above the base 11. The surface of the material cylinder 31 is fixedly connected to... An extension member 32 is attached. The ends of the barrel 31 and the extension member 32 are both located inside the B insertion groove 342. The screw 35 is located inside the barrel 31. The upper end of the three-dimensional mechanism 34 is fixedly connected to the hopper 33. A fixing ring 39 is fixedly connected to the surface of the barrel 31. An injection head 38 is fixedly connected to the end of the barrel 31. Injection holes are opened on the surfaces of the injection head 38, the feed member 28 and the secondary template 24, and multiple injection holes are connected. A U-shaped member 37 is fixedly connected to the surface of the B main plate 27, and the injection head 38 is located inside the U-shaped member 37.

[0031] Specifically, when performing injection molding on the plastic masterbatch, the injection assembly 3 needs to be assembled first. During assembly, the injection head 38 can be placed inside the U-shaped part 37, and the barrel 31 can be placed above the load-bearing part 54. At this time, the barrel 31 will slowly descend under the support of gravity and the telescopic rod 55. When the injection head 38 moves to the opening of the A insertion slot 29, the barrel 31 will stop moving downward. Then, the moving assembly 6 can be used to control the movement of the three-dimensional part 341, so that the barrel 31 can slowly move into the B insertion slot 342. At this time, the screw 35 will slowly insert into the barrel 31. Since the lower end of the barrel 31 is fixedly connected to the extension part 32, when the barrel 31 is inserted into the B insertion slot 342... Inside, the extension 32 can limit the material cylinder 31, thus preventing the material cylinder 31 from deflecting during insertion, which would prevent the plastic masterbatch in the hopper 33 from falling into the material cylinder 31. Since the lower end of the extension 32 has a snap-fit ​​groove, the extension 32 can be snapped in place by the snap-fit ​​component 4, so that the material cylinder 31 can be stably placed inside the three-dimensional mechanism 34. In the specific sampling operation, the screw 35 is driven to rotate by the drive structure 36, so that the plastic masterbatch can be transported inside the material cylinder 31. The plastic masterbatch can be injected between the main template 23 and the secondary template 24 through the injection holes on the injection head 38, the secondary template 24 and the feed part 28, thus completing the subsequent plasticizing operation.

[0032] In this embodiment, the snap-fit ​​assembly 4 includes two outer upright plates 41, both of which are fixedly connected to the upper end of the base 11. An adjustment groove 42 is formed on the surface of each outer upright plate 41. The adjustment groove 42 includes a return part 421, a release part 422, and a limiting part 423, all connected sequentially. The return part 421 and the limiting part 423 are located on the same horizontal plane, while the height of the release part 422 is slightly lower than that of the return part 421 and the limiting part 423. A sealing mechanism 45 is provided inside the three-dimensional component 341. The sealing mechanism 45 includes a sealing member 451, which is fixedly connected to the interior of the three-dimensional component 341. A C-shaped insertion groove 452 is formed on the surface of the sealing member 451. The material cylinder 31 and the extension member 32 are disposed inside the C-shaped insertion groove 452. The ends of both parts abut against the inner wall of the C insertion slot 452. The lower end of the closure part 451 is provided with a through slot 453 and an extension slot 454, which are connected to the A extension slot 343. The snap-fit ​​assembly 4 also includes a snap-fit ​​mechanism 46, which includes an extension part 461. The extension part 461 is slidably connected to the inside of the B extension slot 454. The upper end of the extension part 461 is fixedly connected to a snap-fit ​​part 462, which is located inside the through slot 453. The surface of the extension part 461 is fixedly connected to an extension part 43. The surface of the extension part 43 is fixedly connected to a rectangular part 47, which is slidably connected to the inside of the rectangular slot 344. Both ends of the extension part 43 are rotatably connected to a rolling rod 44, which is located inside the adjustment slot 42.

[0033] Specifically, in practical use, to ensure that the barrel 31 is positioned after being inserted into the B insertion slot 342, preventing it from deflecting or moving and thus falling off during subsequent use, a snap-fit ​​slot is provided at the lower end of the extension 32. During use, the snap-fit ​​piece 462 can be inserted into this slot to limit the position of both the extension 32 and the barrel 31. To facilitate disengagement of the extension 32, the snap-fit ​​piece 462 can be mounted on the extension member 461, which can move vertically within the B extension slot 454. During use, the extension member 461 passes through the through slot 453 to snap the extension 32 in place. When it is necessary to disengage the extension 32, the moving component 6 can be used to move the three-dimensional member 341. When the three-dimensional component 341 moves, it will drive the locking assembly 4 to move together. Since the rolling rod 44 is located inside the adjusting groove 42, the rolling rod 44 will first move along the limiting part 423. At this stage, the injection head 38 can be removed from the A insertion groove 29. After the injection head 38 is removed from the A insertion groove 29, the rolling rod 44 moves to the release part 422. Under the abutment of the inner wall of the release part 422, the rolling rod 44 and the extension part 43 can move downward, which can drive the locking mechanism 46 to move downward, thereby releasing the locking part 462 from the extension part 32. At this time, it is convenient to remove the barrel 31 and the extension part 32. Continue to move the three-dimensional component 341, so that the rolling rod 44 can move along the return part 421, thereby allowing the locking mechanism 46 to return to its original position. When the rolling rod 44 moves to a position slightly behind the middle of the return part 421, as Figure 5 As shown, at this time, the screw 35 is disengaged from the barrel 31, and the barrel 31 can be taken out for cleaning. In actual use, in order to enable the extension part 43 to move vertically up and down, the rectangular part 47 can be fixedly set on the surface of the extension part 43, while the rectangular part 47 is slidably connected to the inside of the rectangular groove 344.

[0034] Furthermore, after cleaning, when the material cylinder 31 needs to be installed, since the material cylinder 31 is set in the specified position, that is, the material cylinder 31 is set on the load-bearing member 54, and the left end of the load-bearing member 54 is in contact with the fixing ring 39, the injection head 38 is located at the opening of the A insertion groove 29. Then, the reverse movement of the position adjustment plate 62 can drive the three-dimensional member 341 to move in the reverse direction, which in turn can drive the rolling rod 44 to move in the reverse direction. The rolling rod 44 will first move inside the return part 421. At this time, the locking mechanism 46 is in the locking position, that is, the locking mechanism 46 is at the highest position. After the rolling rod 44 moves to the release part 422, the locking mechanism 46 will be at its lowest position. Continue to move the three-dimensional member 341, so that the rolling rod 44 moves to the limit part 423. At this time, the locking mechanism 46 returns to the locking position and then engages with the extension member 32.

[0035] In this embodiment, the lifting assembly 5 includes a lifting mechanism 51, a transmission mechanism 52, and an output mechanism 53. Two lifting mechanisms 51, two transmission mechanisms 52, and two output mechanisms 53 are provided. The lifting mechanism 51 includes an A mounting plate 511, and two A mounting plates 511 are provided. Both A mounting plates 511 are fixedly connected to the upper end of the base 11. An A gear 512 is rotatably connected between the two A mounting plates 511. An A rack 513 is slidably connected inside the storage groove 16. 13 meshes with gear A 512. The transmission mechanism 52 includes gear B 521, which is located on the side of the base 11. A rack B 522 is located above the base 11 and meshes with gear B 521. A horizontal moving plate 523 is fixedly connected to the end of rack B 522 and is slidably connected to the surface of the outer plate 41. A rack C 524 is fixedly connected to the end of the horizontal moving plate 523 and meshes with gear A 512. The output mechanism 53 includes two B mounting plates 531, both of which are fixedly connected to the upper end of the base 11. A B gear 521 is rotatably connected to the surface of the B mounting plate 531. A C gear 532 is rotatably connected to the surface of the B mounting plate 531. A D rack 533 is slidably connected inside the B mounting groove 17, and the D rack 533 meshes with the C gear 532. A contact plate 57 is fixedly connected to the ends of the two D racks 533. A lead screw 6... A spring 58 is fitted on the surface of the base 11, and the spring 58 is located between the contact plate 57 and the inner wall of the moving groove 14. A drive shaft 56 is provided at the upper end of the base 11, and the drive shaft 56 is rotatably connected to two B mounting plates 531. Two C gears 532 and B gears 521 are fixedly connected to the surface of the drive shaft 56. A load-bearing member 54 is fixedly connected between the two lifting members 514. A telescopic rod 55 is fixedly connected to the upper end of the base 11, and the load-bearing member 54 is fixedly connected to the telescopic end of the telescopic rod 55.

[0036] Specifically, after the barrel 31 is disengaged from the screw 35, in order to facilitate the removal of the barrel 31 for cleaning, and to reduce the workload of workers and avoid them having to exert considerable effort to lift and remove the barrel 31, during the movement of the three-dimensional component 341, after the barrel 31 is disengaged from the screw 35, the three-dimensional component 341 and the position adjustment plate 62 will continue to move. Then, the position adjustment plate 62 will abut against and push the abutment plate 57 to move. When the abutment plate 57 moves... This will drive rack D 533 to move. Since rack D 533 meshes with gear C 532, it can drive gear C 532 to rotate. And since both gear C 532 and gear B 521 are fixedly connected to the drive shaft 56, gear B 521 can rotate at this time. Since gear B 521 meshes with rack B 522, it can drive rack B 522 to move horizontally. Because rack B 522, the horizontal moving plate 523, and rack C 524 are fixedly connected... The movement of rack B 522 and horizontal moving plate 523 causes rack C 524 to move together. When rack C 524 moves, it meshes with gear A 512, thus driving gear A 512 to rotate. The rotation of gear A 512 causes rack A 513, which meshes with it, to move upward, thereby pushing the lifting member 514 upward. Since the lifting member 514 is located on the side of the load-bearing member 54, it can drive the load-bearing member 54 to move upward, thereby pushing the barrel 31 to rise. When the contact plate 57 moves, it will compress the spring 58 and deform it. When the screw 35 needs to be reinserted into the barrel 31, the three-dimensional member 341 needs to be moved in the opposite direction. At this time, the contact plate 57 will move under the elastic force of the spring 58, which facilitates the next operation. When the barrel 31 is reinserted, the three-dimensional member 341 needs to be driven to move in the opposite direction, so that the barrel 31 can move downward.

[0037] Furthermore, during use, when the rolling rod 44 moves into the release part 422, in order to prevent the material cylinder 31 from continuing to move due to inertia, a fixing ring 39 can be fixed on the surface of the material cylinder 31. When the rolling rod 44 moves into the release part 422, the locking member 462 contacts the locking member 32, and the end of the material cylinder 31 abuts against the load-bearing member 54, thereby preventing the material cylinder 31 from continuing to move.

[0038] Furthermore, in practical use, the lifting component 5 is necessary to automatically lift the barrel during the disassembly process. It directly serves the core objective of easy cleaning, improves the ease of use of the equipment, and since the lifting component 5 does not require an additional power source and control system, it fully utilizes the residual kinetic energy of the injection component 3's retraction, achieving energy saving and system integration. Moreover, the mechanical hard connection ensures strict timing and position synchronization between the lifting action and the screw withdrawal action, avoiding control delays or asynchrony problems that may occur when using independent cylinders or motors. Although there are many parts, they are all standard gears, racks, and shafts, making maintenance and replacement convenient. The long-term operating cost is lower than that of hydraulic / pneumatic systems that require electrical control.

[0039] In this embodiment, the moving component 6 includes a position adjusting plate 62, which is slidably connected to the inside of the moving groove 14. A lead screw 61 is rotatably connected to the inside of the rotating hole 18, and the end of the lead screw 61 is rotatably connected to the inner wall of the moving groove 14. The position adjusting plate 62 is threadedly connected to the surface of the lead screw 61.

[0040] Specifically, in actual use, when it is necessary to control the three-dimensional mechanism 34 to move left and right, an external motor can be fixedly installed on the surface of the base 11. Then, the output end of the external motor can be fixedly connected to the lead screw 61, thereby controlling the lead screw 61 to rotate forward and backward. By rotating the lead screw 61 forward and backward, the position adjustment plate 62 connected to it can be controlled to move left and right, thereby controlling the left and right movement of the three-dimensional mechanism 34. Example 2

[0041] To ensure the representativeness and reproducibility of the sampling results, the following standardized process should be adopted: 1. Raw material pretreatment: The masterbatch and the matrix resin, such as PP, PE, and ABS, are usually dry-mixed in a mixer at a predetermined ratio of 1%-5% for 10-15 minutes to avoid sedimentation and stratification.

[0042] If the masterbatch has strong hygroscopic properties, such as PA, it needs to be dried at 80°C for 2-4 hours, and the moisture content should be controlled at ≤0.02%.

[0043] 2. Equipment Selection: We recommend using a small, all-electric injection molding machine with a clamping force of 50-100 tons and a screw diameter of 20-30mm, which has precise temperature control and back pressure adjustment functions.

[0044] 3. Setting Key Process Parameters: Taking the General PE / PP System as an Example parameter Recommended range illustrate Barrel temperature 180–220°C The setting is based on the melting point of the substrate to avoid overheating and degradation of the color masterbatch. Nozzle temperature 5–10°C lower than the end of the barrel Preventing drooling and thermal decomposition Injection pressure 60–100 MPa Ensure the melt is fully filled to avoid discoloration due to insufficient pressure. Holding pressure 70%–85% of the injection pressure Compensating for shrinkage and improving density and color consistency Holding time 10–40 seconds Positively correlated with product thickness; thicker parts require extended length. back pressure 5–15 MPa It improves the uniformity of mixing, but excessive amounts increase energy consumption and shear heat. mold temperature 30–60°C Low temperatures promote rapid setting and reduce internal stress; high mold temperatures improve surface gloss. Cooldown time 20–60 seconds To ensure proper demolding without deformation, insufficient cooling will affect subsequent testing. Before each sample is made, the barrel must be emptied and residual material must be removed using the "dry injection" method; the injection speed should be kept constant, and a three-stage injection strategy of "slow-fast-slow" should be adopted.

[0045] The evaluation method for color uniformity and dispersion effect should be based on the microscopic rating method explicitly adopted in GB / T 1648-1992 "Polyethylene Color Masterbatch".

[0046] The electronic components and modules used in this invention can all be commonly used parts on the market that can achieve the specific functions described in this case, and the specific models and sizes can be selected and adjusted according to actual needs.

[0047] Of all the devices mentioned above, those requiring transmission effects can choose relatively stable transmission effects available on the market. Depending on the actual environment, protective sleeves or lubricants, protective agents, or other protective materials or shells can be added to the surface of some transmission parts to ensure that the transmission structure does not interfere with the movement of this practical transmission structure, thereby providing external protection for the transmission and preventing rust, deformation, etc.

A method of using an injection molding machine for producing plastic masterbatch, based on the injection molding machine for producing plastic masterbatch as described in claim 9, characterized in that: S1. After completing the previous batch of plastic masterbatch sampling, when it is necessary to clean the barrel (31), first start the external motor, thereby driving the lead screw (61) to rotate. At this time, the position adjustment plate (62) moves away from the plastic component (2), thereby driving the three-dimensional part (341) to move. S2.

And through the transmission of the transmission shaft (56), it will drive the B gear (521) to rotate, which can drive the B rack (522), the horizontal moving plate (523) and the C rack (524) to move. When the C rack (524) moves horizontally, it drives the A gear (512) that meshes with it to rotate, which in turn drives the A rack (513) to move upward. At this time, through the load-bearing component (54), the barrel (31) and the injection head (38) can move upward. S4. After the barrel (31) is moved to the highest point, the worker can remove the barrel (31).
