Description

Technical Field

[0001] The present invention belongs to the field of injection molding, and particularly relates to a vertical injection molding device. Background Art

[0002] Common vertical injection molding machines usually include an injection system, a mold clamping system, a hydraulic system, an electrical control system, a lubrication system, a safety detection system, etc. The injection system is used to heat and plasticize solid plastic to form a molten state and transport it to the mold clamping mechanism for shaping and cooling to form a product. The injection system usually includes a barrel, a screw, a nozzle, and a power transmission device for controlling its movement;

[0003] In practical applications, a drying cylinder for drying granular plastic is usually fixedly installed on the barrel. The plastic is first dried in the drying cylinder and then transported to the barrel for heating and plasticizing to ensure the plastic quality of the product. However, in a vertical injection molding machine, since both the injection system and the drying cylinder are provided on the upper mold and move up and down synchronously during the mold clamping and mold opening processes, after a long time of use, if the screws become loose, it is easy for the heavy drying cylinder to fall and cause a safety accident. At the same time, due to the high installation position of the drying cylinder, workers need to use a ladder or steps to feed the plastic into the drying cylinder, which is not only time-consuming and laborious but also causes great inconvenience in feeding. And using an automated feeding device will increase the production cost significantly. Summary of the Invention

[0005] The present invention discloses a vertical injection molding device, aiming to solve the problems in the prior art that the poor installation position of the drying cylinder leads to inconvenient production, even accidents, and increased production costs.

Detailed implementation manner

[0035] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0036] As Figures 1-3 shown, the present invention discloses a vertical injection molding device, including an injection mechanism 1 and a drying mechanism 2, and a telescopic pipe 3 is connected between the injection mechanism 1 and the drying mechanism 2; during operation, solid plastic needs to be placed in the drying mechanism 2 for heating and drying to prevent the moisture in the plastic from affecting the quality of the final product, and then it is transported to the injection mechanism 1 through the pipe 3 for melting and injection molding;

[0037] It should be noted that in the prior art, the injection mechanism 1 and the drying mechanism 2 are usually arranged on the same floor. At the same time, the connection mode between the drying mechanism 2 and the injection mechanism 1 is usually divided into two types. The first connection mode is to directly fix the drying mechanism 2 on the injection mechanism 1, so that the injection mechanism 1 drives the drying mechanism 2 to move or lift synchronously during the mold opening and closing processes, and under the action of gravity, the plastic drops from the drying mechanism 2 into the injection mechanism 1. However, due to the large weight of the drying mechanism 2, loosening of the fixing screws between the drying mechanism 2 and the injection mechanism 1 is likely to occur after long-term movement and lifting, resulting in the production risk of the drying mechanism 2 falling off. At the same time, the installation position of the drying mechanism 2 in this connection mode is relatively high, causing inconvenience for workers to feed the drying mechanism 2.

[0038] The second connection mode is to place the drying mechanism 2 on the ground, and use an automatic material extraction device to extract the plastic in the drying mechanism 2 at a lower position to the injection mechanism 1 at a higher position. However, this connection mode often has a higher cost and lower space utilization rate. At the same time, since the use of the automatic material extraction device will extract the heat in the drying mechanism 2 and the injection mechanism 1, the drying mechanism 2 and the injection mechanism 1 also need to increase the heating power to ensure the injection and drying temperatures, further increasing the production cost.

[0039] In order to better solve the problems in the prior art, the present invention arranges the drying mechanism 2 and the injection mechanism 1 in a staggered floor manner, that is, the drying mechanism 2 is arranged on the upper floor of the injection mechanism 1. There is a floor slab 6 between the drying mechanism 2 and the injection mechanism 1. The floor slab 6 is provided with through holes 61, and the pipeline 3 slides through the through holes 61 and extends into the upper floor and is connected to the drying mechanism 2. By arranging the drying mechanism 2 and the injection mechanism 1 on different floors respectively, the problems of low space utilization rate and the risk of accidents caused by the falling off of the drying mechanism 2 are well solved. Then, through the telescopic property of the pipeline 3, the active transportation between the drying mechanism 2 and the injection mechanism 1 is well realized. That is to say, the movement of the injection mechanism 1 will not affect the feeding of the drying mechanism 2. At the same time, the power cost for driving the drying mechanism 2 to move and the cost of the material extraction device can be saved, making the production cost lower and the plastic transportation more efficient.

[0040] Specifically, the injection mechanism 1 includes an injection mechanism 4 and a mold clamping mechanism 5. The mold clamping mechanism 5 includes an upper mold 51, a lower mold 52 and a mold driving part 53. The injection mechanism 4 is arranged on the upper mold 51 and is connected to the pipeline 3.

[0041] During use, the mold driving member 53 drives the upper mold 51 and the injection mechanism 4 to move up and down simultaneously, and synchronously drives the telescopic movement of the pipeline 3.

[0042] In one embodiment, as Figure 4 shown, the pipeline 3 includes a rigid straight pipe 31 and a flexible hose 32. The hose 32 is arranged at at least one end of the straight pipe 31, and the other end of the hose 32 is connected to the drying mechanism 2 or the injection mechanism 4. Among them, the straight pipe 31 is used for vertical feeding, so that the plastic automatically slides into the injection mechanism 4 under the action of gravity, reducing the transportation cost and making the feeding smoother; at the same time, due to the flexibility of the telescopic and bending of the hose 32, the lifting movement of the injection mechanism 4 is avoided from restricting or interfering with the feeding.

[0043] Furthermore, in practical applications, the hose 32 can be arranged only at one end of the straight pipe 31. The other end of the straight pipe 31 is connected to the injection mechanism 4, and the other end of the hose 32 is connected to the drying mechanism 2; among them, the hose 32 is arranged above the laminate 6, and one end of the straight pipe 31 passes through the through hole 61 and is connected to the hose 32; during use, the injection mechanism 4 drives the straight pipe 31 to lift and lower synchronously, and the straight pipe 31 slides through the through hole 61, and the hose 32 is located in the upper floor for adaptive bending and telescoping, so that the drying mechanism 2 is always stably connected to the straight pipe 31.

[0044] In another embodiment, as Figure 5 shown, the pipeline 3 includes at least one set of inner pipe 33 and outer pipe 34. The outer pipe 34 is slidably sleeved on the outer periphery of the inner pipe 33, and a sealing ring 35 is tightly abutted between the inner pipe 33 and the outer pipe 34; at the same time, since the bending of the hose 32 in the previous embodiment may cause material jamming or plastic accumulation and blockage in the pipe, therefore, both the inner pipe 33 and the outer pipe 34 in this embodiment are rigid vertical structures. One end of the inner pipe 33 is connected to either the drying mechanism 2 or the injection mechanism 4, and one end of the outer pipe 34 is connected to the other, effectively avoiding the problem of blockage and material jamming of the hose 32 and also taking into account the connection stability between the drying mechanism 2 and the injection mechanism 4;

[0045] At the same time, multiple groups of the inner pipe 33 and the outer pipe 34 can be alternately connected in sequence, further enhancing the telescopic flexibility and movement stability of the pipeline 3 and improving the installation convenience of the pipeline 3;

[0046] Further, an outwardly horizontally extending outer convex ring 331 is provided at the end of the inner tube 33, and an inwardly horizontally extending inner convex ring 341 is provided at the end of the outer tube 34. The sealing ring 35 is arranged between the outer convex ring 331 and the inner convex ring 341. The outer convex ring 331 and the inner convex ring 341 limit the telescopic movement of the pipeline 3, preventing the inner tube 33 and the outer tube 34 from sliding too far and becoming disengaged.

[0047] Specifically, as Figure 6 shown, the drying mechanism 2 includes a drying cylinder 21, a fan 22, a heater 23 and an air duct 24. The fan 22, the heater 23 and the air duct 24 are connected in sequence. The output end of the air duct 24 extends into the drying cylinder 21, and a plurality of drying holes 241 are provided at the end of the air duct 24. During operation, the fan 22 is started to draw air into the drying cylinder 21. The air is heated by the heater 23 and then discharged from the drying holes 241 into the drying cylinder 21, realizing the rapid drying of the solid plastic in the drying cylinder 21.

[0048] Further, a discharge port 211 communicating with the pipeline 3 is provided at the bottom of the drying cylinder 21. A cover plate 212 and a discharge driving member 213 for driving the cover plate 212 to move are provided at the discharge port 211. By connecting the output shaft of the discharge driving member 213 to the cover plate 212, the lateral movement of the cover plate 212 is controlled, thereby achieving the purpose of accurately controlling the opening and closing of the discharge port 211, making the discharge more accurate and highly automated.

[0049] Specifically, as Figure 7 shown, the mold clamping mechanism 5 further includes a frame 54. The lower mold 52 and the mold driving member 53 are arranged on the frame 54. A moving table 55 connected to the output shaft of the mold driving member 53 is provided above the lower mold 52. The injection mechanism 4 and the upper mold 51 are respectively arranged at the top and bottom of the moving table 55. The mold driving member 53 is preferably an oil cylinder. During driving, the output shaft of the mold driving member 53 moves telescopically, thereby driving the moving table 55 and the injection mechanism 4 to move up and down synchronously and realizing the mold opening or mold closing movement of the upper mold 51 and the lower mold 52 synchronously.

[0050] Further, the injection mechanism 4 includes a barrel 41, a nozzle 42, and a screw 43. The nozzle 42 is provided at the end of the barrel 41 and passes through the moving table 55 to be detachably connected to the upper mold 51. A material pipe 513 communicating with the nozzle 42 is provided in the upper mold 51. Threads 431 are provided on the outer peripheral wall of the screw 43 and the screw 43 is arranged in the barrel 41. A heating assembly 411 is provided on the outer peripheral wall of the barrel 41. A bushing 44 is provided at the end of the screw 43. A rotary driving member 45 is provided on the bushing 44. The screw 43 passes through the bushing 44 and is connected to the rotary driving member 45. During use, solid plastic enters the barrel 41 through the pipeline 3 and is plasticized into a molten state under the heating action of the heating assembly 411. At this time, the screw 43 rotates under the rotation of the rotary driving member 45 and stirs and extrudes the plastic in the barrel 41 under the action of the threads 431, so that the molten plastic is filled at the nozzle 42 to prepare for injection molding.

[0051] Furthermore, double-axis driving members 46 are fixedly provided on both sides of the barrel 41. Upper output shafts 462 and lower output shafts 461 are respectively provided at the upper and lower ends of the double-axis driving member 46. The lower output shaft 461 is connected to the moving table 55, and the upper output shaft 462 is connected to the bushing 44. The telescopic movement of the lower output shaft 461 of the double-axis driving member 46 controls the approach or separation of the injection mechanism 4 from the moving table 55. That is to say, under normal working conditions, the lower output shaft 461 is in a contracted state to connect the injection mechanism 4 to the upper mold 51. When it is necessary to stop working or replace the upper mold 51 and the nozzle 42, the lower output shaft 461 needs to be driven to extend and jack up, so that the injection mechanism 4 is separated from the moving table 55, facilitating maintenance or part replacement operations.

[0052] It should be noted that under the rotational stirring action of the screw 43, plastic is continuously extruded at the output end of the barrel 41. The volume of the plastic here gradually increases and pushes the screw 43 upward, causing the upper output shaft 462 to be passively extended. After starting injection molding, the double-axis driving member 46 controls the upper output shaft 462 to contract, so that the screw 43 extrudes the plastic and pushes the plastic into the mold clamping mechanism 5 for injection molding. The double-axis driving member 46 is preferably an oil cylinder.

[0053] Preferably, in order to better observe the feeding situation in the barrel 41 and the pipeline 3, a hopper 47 is provided on the side wall of the barrel 41 and is obliquely upward. A connecting cylinder 48 is connected between the hopper 47 and the pipeline 3. The peripheral wall of the connecting cylinder 48 is made of a transparent material. During actual use, the feeding rate and quantity of the drying mechanism 2 can be adjusted in real time by observing the plastic situation in the connecting cylinder 48.

[0054] More preferably, a detection member 481 for detecting the plastic condition inside the connecting cylinder 48 is provided on the peripheral wall of the connecting cylinder 48, and the detection member 481 is electrically connected to the output end of the drying mechanism 2. That is to say, during the feeding process, when the detection member 481 detects that there is a lack of plastic inside the connecting cylinder 48, the detection member 481 sends an electrical signal to the drying mechanism 2, causing the drying mechanism 2 to convey more plastic into the pipeline 3 for replenishment operation, making the feeding more accurate and automated, and reducing labor costs.

[0055] Specifically, as Figures 8-11 shown, the injection molded product 8 of the present invention is preferably a socket type product. The injection molded product 8 includes a metal pin 81 and a plastic structure housing 82. The housing 82 wraps around one end of the pin 81. In order to better adapt to the production of the injection molded product 8, an injection molding position 521 is provided in the lower mold 52. A plurality of placement grooves 522 are provided in the injection molding position 521. The pin 81 is placed in the placement groove 522. Clamping plates 56 that can approach or move away from each other are provided on both sides of the injection molding position 521. Fixing holes 562 matching the pin 81 are provided in the clamping plates 56. An elastic member 57 is abutted between the side of the clamping plate 56 close to the pin 81 and the lower mold 52, so that the two clamping plates 56 always maintain a state of moving away from each other. Therefore, in the state where the mold is not closed, the placement groove 522 is in a completely exposed state, facilitating the feeding operation of the pin 81;

[0056] Furthermore, a first inclined surface 561 is provided on the outer side of the clamping plate 56, and a pushing block 511 corresponding to the clamping plate 56 is provided at the bottom of the upper mold 51. A second inclined surface 512 corresponding to the first inclined surface 561 is provided on the pushing block 511; after the mold is closed, the two clamping plates 56 approach each other under the mutual abutting action of the first inclined surface 561 and the second inclined surface 512, so that a part of the pin 81 located in the placement groove 522 is arranged in the fixing hole 562. After injection molding, the part of the pin 81 located in the fixing hole 562 will not be wrapped by the plastic, facilitating the use of the injection molded product 8; after the mold is opened, the clamping plate 56 is demolded in the direction away from the injection molded product 8 under the elastic force of the elastic member 57, and then the ejecting mechanism in the lower mold 52 ejects the injection molded product 8;

[0057] Even further, in order to improve production efficiency, multiple injection molded products 8 can be simultaneously injection molded in the injection molding position 521 to form a product assembly 9. The product assembly 9 includes a grasping portion 91 corresponding to the material pipe 513 and a connecting portion 92 connecting the injection molded products 8. After the product assembly 9 is opened and ejected, the discharging and moving operation of the product assembly 9 can be realized only by clamping the grasping portion 91.

[0058] Specifically, as Figures 12-14 shown, in order to improve the discharging convenience of the product component 9, a material taking mechanism 7 is further provided on one side of the mold clamping mechanism 5. The material taking mechanism 7 includes a material taking frame 71, on which a moving rod 72 is slidably connected and a moving driving member 73 for driving the moving rod 72 to move. A clamping jaw 721 that can be opened and closed with each other is provided on the moving rod 72 for clamping the grasping part 91 in the product component 9;

[0059] Furthermore, the moving driving member 73 can be a lead screw, a cylinder or a linear motor, etc.; the clamping jaw 721 can be driven by a finger cylinder;

[0060] Even further, in order to save the cooling time for each injection molding, the worker can discharge the material earlier when the product component 9 is not completely cooled and is roughly solidified. Since in the injection molding process, the injection molding and waiting for cooling time are usually relatively long, discharging the material earlier can better save the production time, thereby improving the production efficiency; however, when discharging the material earlier, since the injection molded products 8 are sequentially connected through the connecting part 92, the two ends of the product component 9 that is not completely cooled and fixed and is in a long strip shape will bend downward under the action of gravity, thereby affecting the quality of the injection molded product 8 (as Figure 13 shown);

[0061] In order to better solve this technical problem, as Figure 14 shown, a supporting rod 722 is further provided on the moving rod 72 in the present invention. The supporting rod 722 is arranged parallel to the clamping jaw 721 up and down. During use, the moving rod 72 drives the clamping jaw 721 and the supporting rod 722 to move synchronously towards the product component 9. When the clamping jaw 721 clamps the grasping part 91 in place, the supporting rod 722 just abuts against the bottom of the product component 9 to support the product component 9, so as to ensure that the two ends of the product component 9 will not bend under the influence of gravity during the discharging process, and further ensure the product quality of the product component 9;

[0062] Preferably, multiple supporting rods 722 can be provided according to the shape requirements of the product component 9 or the injection molded product 8, and a driving mechanism can also be provided between the supporting rod 722 and the moving rod 72 to make the movement of the supporting rod 722 independently controllable and more flexible and convenient.

[0063] Specifically, in order to improve the convenience of placing the pin 81 into the injection molding position 521, a feeding mechanism (not shown) is further provided on the other side of the mold clamping mechanism 5. The feeding mechanism may include a loading component and a feeding component. Workers only need to batch place the pins 81 in the loading component, and the feeding component can automatically place the pins 81 in the loading component into the corresponding placement grooves 522 in appropriate quantities and positions, realizing the automatic feeding of the pins 81, thereby improving the overall efficiency of injection molding and saving more labor costs at the same time;

[0064] Further, as Figure 2 shown, a control console 541 is further provided on the frame 54. The control console 541 is electrically connected to the drying mechanism 2, the injection mechanism 4, the mold clamping mechanism 5, the feeding mechanism, and the material taking mechanism 7 respectively to control the overall injection molding process.

[0065] The working principle of the present invention is described in detail below;

[0066] During the preparation process, solid plastic (material) is first placed in the drying mechanism 2 for drying. After drying, the material is conveyed through the pipeline 3 to the barrel 41. Through the continuous stirring of the screw 43 and the high-temperature heating of the heating component 411, the material is melted and the molten material is gathered on the nozzle 42 waiting for injection molding;

[0067] During injection molding, first place the pin 81 in the injection molding position 521 of the lower mold 52. The upper mold 51 and the injection mechanism 4 press down. Under the action of the clamping plate 56 and the pushing block 511, the clamping plate 56 blocks part of the pin 81. Then the double-axis driving member 46 drives the screw 43 to press down to inject the material into the mold clamping mechanism 5. After injection is completed, cool the mold clamping mechanism 5 with coolant or water. After the injection molded product 8 solidifies, the upper mold 51 and the injection mechanism 4 move upward to open the mold. The clamping plate 56 naturally retracts and demolds under the elastic force of the elastic member 57. Subsequently, the ejecting mechanism in the lower mold 52 ejects the product assembly 9. Finally, the clamping jaw 721 in the material taking mechanism 7 clamps the grasping portion 91 in the product assembly 9, and the support rod 722 abuts and supports the bottom of the product assembly 9, and then takes out the product assembly 9 to complete the injection molding, and waits for the next feeding of the pin 81 for the next round of injection molding operation.

[0068] The innovation of the present invention lies in that the drying mechanism and the injection molding mechanism are respectively arranged on different floors, and then the retractable pipes pass through the floor slabs of the floors and are respectively movably connected to the drying mechanism and the injection molding mechanism, so that the overall space utilization rate of the vertical injection molding equipment is higher, the injection molding operation of workers and the feeding operation of materials are more convenient and safe, and at the same time, the risk of the drying mechanism falling off can be effectively reduced and the overall injection molding cost can be effectively reduced.

[0069] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative manner of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other implementations that can be understood by those skilled in the art.

[0070] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present invention. Any reference signs in the claims should not be regarded as limiting the claims involved.
