Description

Technical Field

[0001] This invention relates to the field of injection molding machine guide rail technology, specifically to an injection molding machine guide rail bracket. Background Technology

[0002] Injection molding machines, also known as injection molding machines or injection machines, are a type of molding equipment used to produce various shapes of plastic products from thermoplastic or thermosetting plastics using plastic molds. They are classified as vertical, horizontal, and all-electric. The working principle of an injection molding machine is similar to that of a syringe. It uses the thrust of a screw or plunger to inject molten plastic into a closed mold cavity. After solidification and shaping, the product is obtained. Injection molding is a cyclical process. Each cycle mainly includes: quantitative feeding—melting and plasticizing—pressure injection—mold filling and cooling—mold opening and part removal. After the plastic part is removed, the mold is closed again to start the next cycle.

[0003] In the actual operation of an injection molding machine, guide rails are installed on both sides of the injection platen. A guiding mechanism is required on the injection platen to ensure linear movement along the guide rails during mold closing, guaranteeing accurate mold alignment and preventing deformation of the injection molded product. The guide rails need to limit the guiding mechanism to ensure linear movement along the guide rails. During use, dust and other debris may accumulate in the guide rails. Over time, as the debris accumulates, the guide rails may become stuck. When the guiding mechanism passes by, it may be squeezed and deformed, and the guiding mechanism may be damaged by impacts. This can cause the injection platen to fail to move along the predetermined trajectory, resulting in deviations during mold closing and preventing the injection molded product from meeting required standards, causing losses. Therefore, we propose an injection molding machine guide rail bracket. Summary of the Invention

[0006] Preferably, each collection chamber is cone-shaped with an opening at its lower end. Each collection chamber has a rotating groove at its lower end, and a rotating shaft is rotatably installed in each rotating groove. Each collection chamber has a cover plate of suitable size below it, and several rotating parts are fixedly installed on each cover plate. Each rotating part is fixedly installed on a corresponding rotating shaft.

[0007] Preferably, each of the cover plates is fixedly mounted with an adapter plate, each of the adapter plates is rotatably mounted with a push plate, each of the push plates is fixedly mounted with a plurality of springs, each of the collection chambers is fixedly mounted with a limit plate, one end of each spring is fixedly connected to the limit plate, and each limit plate and the corresponding collection chamber are provided with a compression groove for limiting the springs and the push plate.

[0008] Preferably, the front support plate is provided with a plurality of holding chambers for collecting debris in the collection chamber, the holding chambers corresponding one-to-one with the collection chambers, and each holding chamber is configured in a conical shape.

[0009] Preferably, the upper end of each cover plate and the upper end of the corresponding holding compartment are located on the same horizontal plane, and each cover plate is provided with a wedge-shaped groove, each wedge-shaped groove cooperating with the inclined surface at one end of the corresponding holding compartment.

[0010] Preferably, each of the holding compartments is provided with a snap-fit ​​groove, and a plurality of snap-fit ​​plates that cooperate with the snap-fit ​​grooves are fixedly installed on the front support plate. The snap-fit ​​plates correspond one-to-one with the snap-fit ​​grooves, and each of the snap-fit ​​plates is fixedly installed with a baffle for limiting the position of the holding compartment.

[0011] Preferably, the height of each wedge block is less than the height of the guide groove, a roller is rotatably mounted on each wedge block, and a limiting groove for limiting the roller is provided on the upper inner wall of each guide groove.

[0016] 1. This invention utilizes guide grooves to limit the bearing, allowing the guiding mechanism to move linearly along the guide rail. Wedge blocks on both sides of the bearing are used to clean the guide groove. When the guide groove is bent or deformed, the wedge blocks will be stuck, causing the corresponding connecting rod and electrode plate to move into the fixing component. When one electrode plate in the fixing component touches the other electrode plate, it indicates that the guide rail is deformed or stuck by debris, which will stop the injection molding machine and prevent the bearing from passing through the obstacle, effectively protecting the guiding mechanism and the guide rail.

[0017] 2. This invention utilizes a collection bin to collect the cleaned debris, preventing it from re-entering the injection molding machine and causing adverse effects. The lower cover of the collection bin is opened through a wedge-shaped opening at the end of the holding bin, allowing the debris to fall into the holding bin for timely cleaning. The elastic force of spring two allows the cover to be reset in time when there is no holding bin limit, reducing the impact of debris on the machine. Attached Figure Description

Detailed Implementation

[0030] 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.

[0031] Please see Figure 1-11This invention provides a technical solution: an injection molding machine guide rail bracket, including an injection molding machine 1, a front support plate 201 and a rear support plate 202 fixedly mounted on the injection molding machine 1, a push rod 203 slidably mounted on the front support plate 201, and an injection plate 3 fixedly mounted on one end of the push rod 203. When the injection molding machine 1 is working, the push rod 203 will drive the injection plate 3 to continuously reciprocate to perform injection molding. A plurality of guide rails 4 are fixedly mounted between the front support plate 201 and the rear support plate 202, and a plurality of connecting parts 5 are fixedly mounted on the injection plate 3. Each connector 5 corresponds to a guide rail 4. Two fixing rods 6 are fixedly installed on each connector 5. The two fixing rods 6 are located on both sides of the corresponding guide rail 4. Each fixing rod 6 is rotatably mounted with a bearing 7. Each guide rail 4 has a guide groove 8 on both sides for limiting the bearing 7. When the push rod 203 drives the injection plate 3 to move, the guide groove 8 limits the bearing 7, so that the connector 5 drives the injection plate 3 to move linearly along the guide rail 4, reducing the possibility of deformation of the injection molded product due to deviation in the movement trajectory of the injection plate 3.

[0032] Two wedge-shaped blocks 11 for cleaning debris are slidably installed in each guide rail 4. The two wedge-shaped blocks 11 are located on both sides of the corresponding bearing 7. The height of each wedge-shaped block 11 is less than the height of the guide groove 8. A roller 10 is rotatably installed on each wedge-shaped block 11 to reduce the friction between the wedge-shaped block 11 and the inner wall of the guide groove 8. The upper inner wall of each guide groove 8 is provided with a limiting groove 9 for limiting the roller 10. By limiting the roller 10 through the limiting groove 9, the roller 10 drives the wedge-shaped block 11 to move linearly along the limiting groove 9. The lower end of each wedge-shaped block 11 is fixedly installed with There is a connecting rod 12, and a fixing member 13 is fixedly installed at the lower end of each fixing rod 6. Each fixing member 13 has a sliding groove 30 at both ends for limiting the connecting rod 12. An electrode plate 29 is fixedly installed at one end of each connecting rod 12. Each electrode plate 29 is slidably installed in the corresponding fixing member 13. A spring-14 is fixedly installed at one end of each electrode plate 29. One end of each spring-14 is fixedly connected to the inner wall of the corresponding fixing member 13. The elastic force of each spring-14 is greater than the weight of the debris. When the injection molding plate 3 drives the connecting member 5 to move, the connecting member 5... The fixed rod 6 drives the corresponding fixed part 13 to move synchronously. The inner wall of the fixed part 13 applies tension and thrust to the two springs 14 respectively. The two springs 14 drive the corresponding electrode plate 29 to move synchronously with the fixed part 13 within the fixed part 13. The two electrode plates 29 drive the corresponding connecting rod 12 and the corresponding wedge block 11 to move. When debris appears in the guide groove 8, since the weight of the debris is less than the elastic force of the spring 14, the debris cannot stop the wedge block 11 from moving and will be pushed out of the guide groove 8 along the inclined surface of the wedge block 11. When the guide rail 4 bends or deforms, or When debris gets stuck in the guide groove 8, one side of the wedge block 11 will be stuck, causing the corresponding connecting rod 12 and the corresponding electrode 29 to stop moving, and causing the corresponding spring 14 to stretch. Since the fixing part 13 drives the other side of the electrode 29 to continue moving, the two electrode 29s will slide relative to each other in the fixing part 13 and eventually come into contact. When the two electrode 29s in the fixing part 13 come into contact, it indicates that the guide rail 4 is deformed or stuck by debris, which will stop the injection molding machine 1 from working and prevent the bearing 7 from passing through the obstacle, effectively protecting the bearing 7 and the guide rail 4.

[0033] Each connector 5 is fixedly equipped with a collection chamber 15 for collecting debris from the guide groove 8. Each collection chamber 15 is conical and made of rigid material, and its inner wall is smooth to facilitate the sliding of debris. When debris is cleaned out of the guide groove 8, it will fall into the collection chamber 15 below under the influence of gravity and slide to the bottom of the collection chamber 15. The lower end of each collection chamber 15 is open and equipped with a rotating groove 18. A rotating shaft 19 is rotatably installed in each rotating groove 18. Each collection chamber 15 is equipped with a cover plate 16 of appropriate size below it. Several rotating parts 20 are fixedly installed on each cover plate 16. Each rotating part 20 is fixedly installed on a corresponding rotating shaft 19. A connecting plate 21 is fixedly installed, and a push plate 22 is rotatably installed on each connecting plate 21. Several springs 23 are fixedly installed on each push plate 22. A limit plate 24 is fixedly installed on each collection chamber 15. One end of each spring 23 is fixedly connected to the limit plate 24. Each limit plate 24 and the corresponding collection chamber 15 are provided with a compression groove 31 for limiting the springs 23 and the push plate 22. The elastic force of the springs 23 drives the push plate 22 to move downward along the compression groove 31, so that the corresponding cover plate 16 rotates around the pivot 19 and is in contact with the bottom of the corresponding collection chamber 15, preventing the debris in the collection chamber 15 from falling out and re-entering the injection molding machine 1, which would cause adverse effects.

[0034] The front support plate 201 is provided with several holding chambers 26 for collecting debris from the collection chamber 15. Each holding chamber 26 corresponds one-to-one with the collection chamber 15. Each holding chamber 26 is conical and made of rigid material, and its inner wall is smooth to facilitate the sliding of debris. Each holding chamber 26 is provided with a snap-fit ​​groove 28. Several snap-fit ​​plates 27 that cooperate with the snap-fit ​​grooves 28 are fixedly installed on the front support plate 201. Each of the snap-fit ​​plates 27 corresponds one-to-one with the snap-fit ​​slot 28, and each snap-fit ​​plate 27 is fixedly installed with a baffle 25 for limiting the position of the holding compartment 26, so that the holding compartment 26 is fixed on the front support plate 201. The upper end of each cover plate 16 is on the same horizontal plane as the upper end of the corresponding holding compartment 26, and each cover plate 16 is provided with a wedge groove 17. Each wedge groove 17 cooperates with the inclined surface at one end of the corresponding holding compartment 26. When the collection compartment 15 moves the corresponding cover plate 16... Upon reaching the corresponding holding chamber 26, the corresponding baffle 25 prevents the holding chamber 26 from moving backward. One end of the holding chamber 26 is engaged in the wedge-shaped groove 17. As the collecting chamber 15 continues to move forward on the support plate 201, the outer inclined surface of one end of the holding chamber 26 limits the cover plate 16, causing the cover plate 16 to rotate downward about the pivot 19. Debris on the cover plate 16 slides along the inner inclined surface of the corresponding holding chamber 26 to the bottom of the holding chamber 26. When one end of the cover plate 16 rotates downward, the other end... The end adapter plate 21 drives the corresponding push plate 22 to move upward along the compression groove 31, and compresses the springs 23. When the collection chamber 15 drives the cover plate 16 to move backward to the support plate 202, the outer slope of the holding chamber 26 releases the restriction on the cover plate 16. The spring force of the spring 23 pushes the push plate 22 downward along the compression groove 31 again, so that the corresponding cover plate 16 rotates upward about the pivot 19 and re-fits with the bottom of the corresponding collection chamber 15.

[0035] Working principle: When the injection molding machine 1 is working, the push rod 203 will drive the injection plate 3 to continuously reciprocate for injection molding. The guide groove 8 limits the bearing 7, causing the connecting piece 5 to drive the injection plate 3 to move linearly along the guide rail 4, reducing the possibility of deformation of the injection molded product due to deviation in the movement trajectory of the injection plate 3. The limiting groove 9 limits the roller 10, causing the roller 10 to drive the wedge block 11 to move linearly along the limiting groove 9. When the injection plate 3 drives the connecting piece 5, the fixing rod 6 on the connecting piece 5 drives the corresponding fixing piece 13 to move synchronously. The inner wall of the fixing piece 13 applies tension and thrust to the two springs 14 respectively, and the two springs 14 drive the corresponding electrodes... The electrode 29 moves synchronously within the fixing member 13. The two electrode 29s drive the corresponding connecting rod 12 and the corresponding wedge block 11 to move. When debris appears in the guide groove 8, because the weight of the debris is less than the elastic force of the spring 14, the debris cannot stop the movement of the wedge block 11 and will be pushed out of the guide groove 8 along the inclined surface of the wedge block 11. When the guide rail 4 bends or deforms, or when debris is stuck in the guide groove 8, one side of the wedge block 11 will be stuck, causing the corresponding connecting rod 12 and the corresponding electrode 29 to stop moving, and stretching the corresponding spring 14. Because the fixing member 13 drives the other electrode 29 to continue moving, the two electrode 29s will be... Relative sliding occurs within the components, eventually leading to contact. When the two electrode plates 29 within the fixing member 13 contact, it indicates that the guide rail 4 is deformed or stuck by debris, causing the injection molding machine 1 to stop working and preventing the bearing 7 from passing through the obstruction, effectively protecting the bearing 7 and the guide rail 4. When the debris is cleared from the guide groove 8, it will fall into the lower collection chamber 15 under gravity and slide to the bottom of the collection chamber 15. When the collection chamber 15 moves the corresponding cover plate 16 to the corresponding holding chamber 26, the corresponding baffle 25 prevents the holding chamber 26 from moving backward, and one end of the holding chamber 26 is stuck in the wedge groove 17. As the collection chamber 15 continues to move forward on the support plate 201, one end of the holding chamber 26... The outer inclined surface limits the cover plate 16, causing the cover plate 16 to rotate downward about the pivot 19. Debris on the cover plate 16 slides into the bottom of the corresponding holding compartment 26 along the inner inclined surface. When one end of the cover plate 16 rotates downward, the connecting plate 21 at the other end drives the corresponding push plate 22 to move upward along the compression groove 31, and compresses the springs 23. When the collection compartment 15 moves the cover plate 16 to the rear support plate 202, the outer inclined surface of the holding compartment 26 releases the limitation on the cover plate 16. The elastic force of the springs 23 pushes the push plate 22 downward along the compression groove 31 again, causing the corresponding cover plate 16 to rotate upward about the pivot 19 and re-fit with the bottom of the corresponding collection compartment 15.
