Abstract
Description
Technical Field
[0001] This utility model relates to the field of injection molding machine technology, and in particular to a sliding component for injection molding machines. Background Technology
[0002] An injection molding machine is a primary molding equipment used to produce various shapes of plastic products from thermoplastic or thermosetting plastics using plastic molds. During the injection molding process, the injection nozzle is installed at the bottom of the swing arm, and the injection nozzle is moved by the horizontal and vertical movement of the swing arm.
[0003] In the prior art, such as the sliding component for a two-color injection molding machine disclosed in Chinese Patent Publication No. CN217098601U, there are connecting plates, movable blocks, and injection boxes. Operating blocks are symmetrically fixed between the connecting plates. Sliding grooves are provided on the upper and lower surfaces of the operating blocks. Assembly holes are symmetrically provided on the movable blocks. Mounting vertical plates are symmetrically fixed on the top and bottom surfaces of the inner walls of the assembly holes. A fixing rod is fixed between the mounting vertical plates. A pulley is movably mounted on the fixing rod. The assembly holes on the movable blocks correspond to the operating blocks for movable assembly, and the pulleys and sliding grooves are correspondingly engaged. This sliding component for a two-color injection molding machine solves the problem of slow and uneven movement of the movable block under its own weight, especially when the lubrication between the pull rod and the movable block is poor, which causes instability in the movement of the injection box containing the injection liquid.
[0004] While the aforementioned patents can achieve smooth movement, the swing arm connecting the injection nozzle needs to move laterally and longitudinally. The patents can only achieve lateral sliding and cannot achieve longitudinal sliding, which prevents the injection nozzle from rising and falling. Therefore, the above problems need to be improved. Utility Model Content
[0005] The purpose of this invention is to provide a sliding component for an injection molding machine, which has the effect of sliding laterally and longitudinally.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a sliding component for an injection molding machine, comprising a horizontal plate, an electric slide rail fixedly installed on the outside of the horizontal plate, a moving block fixedly connected to the output end of the electric slide rail, a column fixedly connected to one side of the moving block, a support rail fixedly connected to the side of the horizontal plate, a connecting shaft fixedly connected to the outside of the column, a support wheel rotatably connected to the outside of the connecting shaft, the support wheel slidably connected to the inside of the support rail, a guide block fixedly connected to one side of the column, a cylinder fixedly installed on the outside of the guide block, a push rod fixedly connected to the output end of the cylinder, a moving column fixedly connected to one end of the push rod, an injection nozzle provided at the bottom of the moving column, grooves provided on both sides inside the guide block, a guide wheel rotatably connected inside the grooves, and linear rails fixedly connected to both sides inside the moving column, the guide wheel extending into the interior of the linear rail and slidably connected to the linear rail.
[0007] By adopting the above technical solution, when the injection nozzle is laterally slidable, the column is driven to move laterally by an electric slide rail, thus enabling the injection nozzle to move laterally. During this process, the support wheel slides inside the support rail, thereby driving the column to move and improving the stability of the column during the sliding process. When the injection nozzle needs to be laterally slidable, the push rod is extended and retracted by a cylinder, causing the push rod to pull the moving column to move, thus enabling the moving column to rise and fall, allowing the injection nozzle to slide longitudinally. During this process, the guide wheel extends into the interior of the linear rail and maintains a sliding connection with the linear rail. The linear rail is straight, thus enabling the linear rail to drive the moving column to move linearly, preventing the moving column from deviating during the movement. This device can not only perform lateral and longitudinal displacement of the injection nozzle, but also the movement process is smooth and the movement effect is highly stable.
[0008] A further feature of this invention is that the number of guide wheels is several, and the several guide wheels are evenly distributed on both sides of the outside of the guide block.
[0009] By adopting the above technical solution, there are two linear guides and two sets of guide wheels, with each set of guide wheels extending into the interior of each linear guide.
[0010] A further feature of this invention is that: a cavity is provided inside the movable column, and an injection pipe is fixedly connected inside the injection nozzle, the injection pipe extending through the cavity to the outside of the movable column.
[0011] By adopting the above technical solution, the injection plastic enters the interior of the injection nozzle through the injection pipe, and then the injection nozzle sprays the injection plastic.
[0012] A further feature of this invention is that a rectangular groove is provided on one side of the outer side of the column, and a movable block is provided inside the rectangular groove.
[0013] By adopting the above technical solution, the moving block is set inside the rectangular groove and extends to the outside of the rectangular groove.
[0014] A further feature of this invention is that a motor is fixedly installed on the top of the column, a threaded shaft is fixedly connected to the output end of the motor, a sleeve is threadedly connected to the outside of the threaded shaft, and the moving block is fixedly connected to the outside of the sleeve.
[0015] By adopting the above technical solution, the motor is started, which drives the threaded shaft to rotate. The sleeve and the moving block will rise and fall. The injection pipe is set inside the moving block, which can limit the injection pipe inside the moving block. The rising and falling of the moving block prevents the injection pipe from being dragged to the ground, thus achieving the effect of protecting the injection pipe.
[0016] A further feature of this invention is that a central shaft is fixedly connected to both sides inside the movable block, and a limit wheel is rotatably connected to the outside of the central shaft.
[0017] By adopting the above technical solution, the injection molding pipe is limited between two limit wheels. When the injection molding pipe is pulled out, the rotation of the limit wheels maintains smoothness.
[0018] A further feature of this invention is that the number of the limiting wheels is two, and the two limiting wheels are symmetrical to each other.
[0019] By adopting the above technical solution, two limiting wheels are distributed on the left and right sides of the moving block, and the two limiting wheels are on the same horizontal line.
[0020] A further feature of this invention is that a gap is left between the two limiting wheels, and a cotton layer is fixedly connected to the outside of both limiting wheels.
[0021] By adopting the above technical solution, when the injection pipe extends into the gap between the two limiting wheels, it will come into contact with the cotton layer outside the limiting wheels.
[0022] A further feature of this invention is that a cylinder frame is fixedly connected to the outside of the guide block, and the cylinder is installed inside the cylinder frame.
[0023] By adopting the above technical solution, the cylinder is fixed to the outside of the guide block by the cylinder bracket, which improves the stability of the cylinder during operation.
[0024] A further feature of this invention is that a mounting hole is provided on the back of the horizontal plate, and the mounting hole is circular.
[0025] By adopting the above technical solution, the mounting hole is used to install the horizontal plate into the interior of the injection molding machine.
[0026] The beneficial effects of this utility model are:
[0027] 1. This utility model, through the arrangement of a horizontal plate, electric slide rail, column, support rail, connecting shaft, support wheel, guide block, cylinder, push rod, moving column, injection nozzle, groove, guide wheel, and linear rail, allows the injection nozzle to slide laterally. When the injection nozzle slides laterally, the electric slide rail drives the column to move laterally, thus enabling the injection nozzle to move laterally. During this process, the support wheel slides inside the support rail, allowing the support wheel to drive the column to move, improving the stability of the column during sliding. When the injection nozzle needs to slide longitudinally, the cylinder drives the push rod to extend and retract, causing the push rod to pull the moving column to move, thus enabling the moving column to rise and fall, allowing the injection nozzle to slide longitudinally. During this process, the guide wheel extends into the linear rail and maintains a sliding connection with the linear rail. The linear rail is straight, thus enabling the linear rail to drive the moving column to move linearly, preventing the moving column from deviating during movement. This device can not only perform lateral and longitudinal displacement of the injection nozzle, but also ensures smooth movement and strong stability.
[0028] 2. This utility model, through the arrangement of an injection pipe, cavity, rectangular groove, moving block, motor, threaded shaft, sleeve, central shaft, and limiting wheels, allows the injection plastic to enter the interior of the injection nozzle through the injection pipe, and then be sprayed through the injection nozzle. The moving block is located inside the rectangular groove and extends to the outside of the rectangular groove. When the motor is started, it drives the threaded shaft to rotate, causing the sleeve and moving block to rise and fall. The injection pipe is located inside the moving block, thus limiting the injection pipe within the moving block. The rising and falling of the moving block prevents the injection pipe from being dragged to the ground, achieving a protective effect for the injection pipe. The injection pipe is limited between two limiting wheels, and when the injection pipe is pulled out, the rotation of the limiting wheels maintains smoothness. Attached Figure Description

[0036] Reference Figure 1-4 A sliding component for an injection molding machine includes the following specific embodiments:
[0037] Example 1: A sliding assembly for an injection molding machine includes a horizontal plate 1. An electric slide rail 2 is fixedly installed on the outside of the horizontal plate 1. A moving block is fixedly connected to the output end of the electric slide rail 2. A column 3 is fixedly connected to one side of the moving block. A support rail 4 is fixedly connected to the side of the horizontal plate 1. A connecting shaft 5 is fixedly connected to the outside of the column 3. A support wheel 6 is rotatably connected to the outside of the connecting shaft 5 and is slidably connected inside the support rail 4. A guide block 7 is fixedly connected to one side of the column 3. A cylinder 8 is fixedly installed on the outside of the guide block 7. A push rod 9 is fixedly connected to the output end of the cylinder 8. A moving column 10 is fixedly connected to one end of the push rod 9. An injection nozzle 11 is provided at the bottom of the moving column 10. Grooves 12 are provided on both sides inside the guide block 7. A guide wheel 13 is rotatably connected inside the groove 12. Linear rails 14 are fixedly connected to both sides inside the moving column 10. The guide wheel 13 extends into the interior of the linear rail 14 and is slidably connected to the linear rail 14. When the injection nozzle 11 slides laterally, the column 3 is driven to move laterally by the electric slide rail 2, thereby enabling the injection nozzle 11 to move laterally. During this process, the support wheel 6 will slide inside the support rail 4, thereby enabling the support wheel 6 to drive the column 3 to move, improving the stability of the column 3 during the sliding process. When the injection nozzle 11 needs to be slid longitudinally, the cylinder 8 drives the push rod 9 to extend and retract, thereby enabling the push rod 9 to pull the moving column 10 to move, thereby enabling the moving column 10 to move up and down, allowing the injection nozzle 11 to slide longitudinally. During this process, the guide wheel 13 extends into the interior of the linear rail 14 and maintains a sliding connection with the linear rail 14. The linear rail 14 is straight, thereby enabling the linear rail 14 to drive the moving column 10 to move linearly, preventing the moving column 10 from deviating during the movement. This device can not only move the injection nozzle 11 laterally and longitudinally, but also move smoothly and with strong stability.
[0038] Example 2: The number of guide wheels 13 is several, and the several guide wheels 13 are evenly distributed on both sides of the outside of the guide block 7. By adopting the above technical solution, the number of linear rails 14 is two, and the number of guide wheels 13 is two sets, with each set of guide wheels 13 extending into the interior of each linear rail 14.
[0039] Example 3: A cavity 16 is provided inside the movable column 10. An injection pipe 15 is fixedly connected inside the injection nozzle 11. The injection pipe 15 passes through the cavity 16 and extends to the outside of the movable column 10. The injection plastic enters the injection nozzle 11 through the injection pipe 15 and is then sprayed by the injection nozzle 11. A rectangular groove 17 is provided on one side of the outside of the column 3. A movable block 18 is provided inside the rectangular groove 17 and extends to the outside of the rectangular groove 17. A motor 19 is fixedly installed on the top of the column 3. A threaded shaft 20 is fixedly connected to the output end of the motor 19. A sleeve 21 is threadedly connected to the outside of the threaded shaft 20. The movable block 18 is fixedly connected to the outside of the sleeve 21. When the motor 19 is started, it drives the threaded shaft 20 to rotate. The sleeve 21 and the movable block 18 will move up and down. The injection pipe 15 is located on the movable column 10. The inside of the movable block 18 can limit the injection pipe 15 inside the movable block 18, and the lifting and lowering of the movable block 18 can prevent the injection pipe 15 from being dragged to the ground, thus achieving the effect of protecting the injection pipe 15. The two sides inside the movable block 18 are fixedly connected to the central shaft 22, and the outside of the central shaft 22 is rotatably connected to the limiting wheel 23. The injection pipe 15 is limited between the two limiting wheels 23. When the injection pipe 15 is pulled out, the rotation of the limiting wheel 23 maintains smoothness. There are two limiting wheels 23, and the two limiting wheels 23 are symmetrical to each other. The two limiting wheels 23 are distributed on the left and right sides of the movable block 18, and the two limiting wheels 23 are on the same horizontal line. There is a gap between the two limiting wheels 23. The outside of the two limiting wheels 23 is fixedly connected to the cotton layer. When the injection pipe 15 extends into the gap between the two limiting wheels 23, it will contact the cotton layer outside the limiting wheel 23.
[0040] Example 4: A cylinder frame 24 is fixedly connected to the outside of the guide block 7. The cylinder 8 is installed inside the cylinder frame 24. The cylinder 8 is fixed to the outside of the guide block 7 through the cylinder frame 24, which improves the stability of the cylinder 8 during operation. The back of the horizontal plate 1 is provided with a mounting hole. The mounting hole is round and is used to install the horizontal plate 1 into the inside of the injection molding machine.
[0041] In this invention, when the injection nozzle 11 is laterally slidable, the column 3 is driven to move laterally by the electric slide rail 2, thereby enabling the injection nozzle 11 to move laterally. During this process, the support wheel 6 slides inside the support rail 4, thereby driving the column 3 to move and improving the stability of the column 3 during the sliding process. When the injection nozzle 11 needs to be laterally slidable, the cylinder 8 drives the push rod 9 to extend and retract, causing the push rod 9 to pull the moving column 10 to move, thereby enabling the moving column 10 to move up and down, allowing the injection nozzle 11 to slide longitudinally. During this process, the guide wheel 13 extends into the interior of the linear rail 14 and maintains a sliding connection with the linear rail 14. The linear rail 14 is straight, thereby enabling the linear rail 14 to drive the moving column 10 to move linearly, preventing the moving column 10 from deviating during the movement. This device does not... It can only move the injection nozzle 11 laterally and longitudinally, and the movement process is smooth and the movement effect is stable. The injection plastic enters the interior of the injection nozzle 11 through the injection pipe 15, and then the injection plastic is sprayed through the injection nozzle 11. The moving block 18 is set inside the rectangular groove 17 and extends to the outside of the rectangular groove 17. The motor 19 is started, so that the motor 19 drives the threaded shaft 20 to rotate. The sleeve 21 and the moving block 18 will form a lifting and lowering. The injection pipe 15 is set inside the moving block 18, which can limit the injection pipe 15 inside the moving block 18. The lifting and lowering of the moving block 18 prevents the injection pipe 15 from being dragged to the ground, achieving the effect of protecting the injection pipe 15. The injection pipe 15 is limited between two limit wheels 23. When the injection pipe 15 is pulled out, the rotation of the limit wheels 23 maintains smoothness.
[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
