Description

Technical Field

[0001] This utility model relates to the field of injection molding machine technology, and specifically to a stable connecting device for the slide plate mechanism of an injection molding machine. Background Technology

[0002] With the development of production and the advancement of technology, injection molding machines play an important role in modern manufacturing. Vertical injection molding machines feed raw materials through a slide mechanism. The slide mechanism usually uses a drive shaft to move the slide. Therefore, it is necessary to ensure the coaxiality of the drive shaft and the slide. If there is an angular deviation between the drive shaft and the slide, the slide may get stuck and unable to move. Therefore, a connector needs to be installed between the drive shaft and the slide to ensure the coaxiality between the drive shaft and the slide.

[0003] For example, patent document with patent application number 201520094610.2 and publication date of July 29, 2015 discloses a single-slide injection molding mechanism, including a fixed slide, a movable slide, a lower slide, a slide cylinder, and a slide rail. The fixed slide is fixed on the lower template, and the slide rail is fixed on both sides of the movable slide. Both sides of the fixed slide and the slide rail are provided with guide rail surfaces. The slide cylinder is fixed on the side of the lower template. It also includes a slide cylinder shaft connecting block. The movable slide has a notch in the center on one side corresponding to the slide cylinder. The slide cylinder shaft connecting block is a cuboid and fixed in the notch of the movable slide. The side has a receiving hole for accommodating the slide cylinder shaft of the slide cylinder. The slide cylinder shaft of the slide cylinder is connected to the movable slide through the slide cylinder shaft connecting block.

[0004] In the above literature, the cylinder shaft of the slide plate cylinder is connected to the cylinder shaft connecting block, which is placed in the recess of the moving slide plate. Pressure blocks are used on both sides to press the cylinder shaft connecting block. Because a connection position between the slide plate cylinder shaft and the cylinder shaft connecting block needs to be left between the two pressure blocks, stress will concentrate on both sides of the cylinder shaft connecting block when the slide plate cylinder shaft drives the moving slide plate. Over long-term use, this causes wear and deformation of the cylinder shaft connecting block. When the end face where the cylinder shaft contacts the pressure block deforms, the slide plate cylinder shaft can easily shift when it drives the cylinder shaft connecting block, thus affecting the coaxiality between them. Furthermore, since the pressure block and the cylinder shaft connecting block are separate units, connected only by external pressing, and the cylinder shaft connecting block is located in the recess, the cylinder shaft connecting block needs to be flush with the three surfaces of the recess for reliable installation. This requires a high degree of flatness between the recess and the three surfaces of the cylinder shaft connecting block, resulting in complex processing. The connection method described above is prone to loosening due to vibration, impact, and other factors during long-term use. Summary of the Invention

[0005] This utility model provides a stable connecting device for the slide plate mechanism of an injection molding machine, which has high coaxiality, long service life, and simple processing.

[0006] To achieve the above objectives, the technical solution of this utility model is: a stable connecting device for a sliding plate mechanism of an injection molding machine, used for connecting the movable sliding plate and the driving component in the sliding plate mechanism, including a connecting block, one end of the connecting block is provided with a groove recessed towards the driving component, a first mounting hole and an assembly part are respectively provided on both sides of the groove of the connecting block, the movable sliding plate is provided with a second mounting hole corresponding to the position of the first mounting hole, the assembly part passes through the first mounting hole and connects to the second mounting hole, a third mounting hole is provided in the middle of the connecting block, and the third mounting hole is connected to the driving component.

[0007] The above configuration includes a groove in the connecting block that is recessed into the driving component. This allows the connecting block to connect with the moving slide plate only on both sides of the groove. This eliminates the need to ensure the flatness between the connecting block and the moving slide plate on both sides of the groove, reducing the complexity of machining the surface. During assembly, alignment and installation are achieved through the first and second assembly holes, reducing adjustment time, improving assembly efficiency, and better ensuring the coaxiality of the moving slide plate and the connecting block. This ensures that the moving slide plate and the connecting block maintain a consistent motion trajectory during movement.

[0008] Furthermore, the connecting block is provided with a first mounting hole and an assembly on both sides. The assembly can be a bolt. The movable slide is provided with a second mounting hole corresponding to the first mounting hole. The assembly passes through the first mounting hole and connects with the second mounting hole, which can effectively prevent the connecting block and the movable slide from loosening or falling off. The fastening effect of the assembly can further ensure that the connecting block and the movable slide remain coaxial in the radial direction, thereby achieving coaxial alignment between the connecting block and the movable slide.

[0009] Furthermore, the connecting block includes an assembly part, and a boss is provided in the middle of one side of the assembly part, the cross-sectional area of ​​the assembly part being larger than the cross-sectional area of ​​the boss.

[0010] With the above configuration, the assembly part contacts the moving slide plate. The cross-sectional area of ​​the assembly part is larger than that of the boss part. The larger cross-sectional area can disperse the friction between the connecting block and the moving slide plate, so that the friction can be distributed more evenly and reduce local wear.

[0011] Furthermore, the groove is located in the middle of one side of the assembly part.

[0012] The above configuration, with the groove located in the middle of one side of the assembly part, allows for precise matching with the movable slide plate.

[0013] Furthermore, a fixed slide plate is provided on the lower side of the movable slide plate, the movable slide plate and the fixed slide plate are slidably connected, the fixed slide plate is mounted on the side of the protrusion, and the mounting plate is provided with a through hole in the middle.

[0014] With the above setup, the moving slide plate and the fixed slide plate are slidably connected, and the moving slide plate can be driven to slide on the fixed slide plate by the drive component.

[0015] Furthermore, the third mounting hole is connected to the drive component via fasteners, the fasteners including a fastening screw and a fastening bolt. The fastening screw is connected to the third mounting hole, and the fastening bolt is connected to the fastening screw. The drive component includes a drive cylinder, and the output shaft of the drive cylinder passes through a through hole and is connected to the fastening screw.

[0016] The above setup allows the fastening bolts to further enhance the stability of the connection between the fastening screw and the connecting block. The output shaft of the drive cylinder passes through the through hole and is connected to the fastening screw. This ensures that the output shaft of the drive cylinder is transmitted to the connecting block through the fastening screw, reducing errors in the intermediate links. At the same time, it avoids the output shaft of the drive cylinder being directly connected to the connecting block, which could cause wear on the connecting block.

[0017] Furthermore, the third mounting hole is located in the middle of one side of the boss portion.

[0018] With the above configuration, the third mounting hole is located in the middle of one side of the boss portion, which can serve as a precise connection point between the connecting block and the driving component. The fixing function of the third mounting hole can improve the stability of the connecting device.

[0019] Furthermore, the first assembly hole is provided through the connecting block.

[0020] The above-mentioned design, including the through-hole first assembly hole, provides a connection position for the assembly parts, allowing the connecting block and the moving slide to connect and improving assembly accuracy. Attached Figure Description

[0028] Example 1.

[0029] like Figures 1 to 6 As shown, a stable connecting device for an injection molding machine slide mechanism is used to connect the movable slide 3 and the driving component 1 in the slide mechanism. The connecting device includes a connecting block 4. One end of the connecting block 4 is provided with a groove 41 recessed towards the driving component. The groove 41 is connected to a protrusion. The two sides of the groove of the connecting block 4 are respectively provided with a first mounting hole 421 and an assembly part. The movable slide 3 is provided with a second mounting hole corresponding to the position of the first mounting hole 421. The assembly part passes through the first mounting hole 421 and is connected to the second mounting hole. The middle of the connecting block 4 is provided with a third mounting hole 431, which is connected to the driving component 1. During assembly, the groove 41 and the protrusion can be more easily aligned and installed, reducing adjustment time, improving assembly efficiency, and better ensuring the coaxiality of the movable slide 3 and the connecting block 4, ensuring that the movable slide 3 and the connecting block 4 maintain a consistent motion trajectory during the movement.

[0030] Furthermore, the connecting block 4 is provided with a first mounting hole 421 and an assembly part on both sides. The assembly part can be a bolt. The movable slide plate 3 is provided with a second mounting hole corresponding to the position of the first mounting hole 421. The assembly part passes through the first mounting hole 421 and connects with the second mounting hole, which can effectively prevent the connecting block 4 and the movable slide plate 3 from loosening or falling off. The fastening effect of the assembly part can further ensure that the connecting block 4 and the movable slide plate 3 remain coaxial in the radial direction, thereby achieving coaxial alignment between the connecting block 4 and the movable slide plate 3.

[0031] like Figure 2-5 As shown, the connecting block 4 includes an assembly part 42, and a boss part 43 is provided in the middle of one side of the assembly part 42. The cross-sectional area of ​​the assembly part 42 is larger than the cross-sectional area of ​​the boss part 43. The assembly part 42 contacts the movable slide plate 3. The larger cross-sectional area of ​​the assembly part 42 can disperse the friction between the connecting block 4 and the movable slide plate 3, so that the friction can be distributed more evenly and reduce local wear.

[0032] The groove 41 is located in the middle of one side of the assembly part 42, and the third assembly hole 431 is located in the middle of one side of the boss part 43. The groove 41, located in the middle of one side of the assembly part 42, can precisely cooperate with the protrusion on the movable slide plate 3. The third assembly hole 431, located in the middle of one side of the boss part 43, can serve as a precise connection point between the connecting block 4 and the driving member 1. The cooperation between the groove 41 and the protrusion can reduce the relative movement between the connecting block 4 and the movable slide plate 3, thereby reducing friction. The cooperation between the groove 41 and the protrusion, as well as the fixing effect of the third assembly hole 431, can improve the stability of the connecting device.

[0033] A fixed slide plate 2 is provided on the lower side of the movable slide plate 3. The movable slide plate 3 and the fixed slide plate 2 are slidably connected. The fixed slide plate 2 is mounted on the side of the protrusion. A through hole is provided in the middle of the mounting seat. The movable slide plate 3 and the fixed slide plate 2 are slidably connected. The movable slide plate 3 can be driven to slide on the fixed slide plate 2 by the driving component 1.

[0034] The third mounting hole 431 is connected to the drive component 1 by fasteners, including a fastening screw and a fastening bolt. The fastening screw is connected to the third mounting hole 431, and the fastening bolt is connected to the fastening screw. The drive component 1 includes a drive cylinder 11. The output shaft of the drive cylinder 11 passes through a through hole and is connected to the fastening screw. The fastening bolt can further strengthen the stability of the connection between the fastening screw and the connecting block 4. The output shaft of the drive cylinder 11 passes through a through hole and is connected to the fastening screw. This can ensure that the output shaft of the drive cylinder 11 is transmitted to the connecting block 4 through the fastening screw, reducing the error of the intermediate links, and at the same time avoiding the direct connection between the output shaft of the drive cylinder 11 and the connecting block 4, which would cause the connecting block 4 to wear.

[0035] The protrusion is set along the middle of one side of the moving slide plate 3. Setting the protrusion along the middle of one side of the moving slide plate 3 can ensure that the moving slide plate 3 is subjected to more uniform force during movement. The protrusion along the middle of one side of the moving slide plate 3 can effectively reduce stress concentration caused by eccentricity and improve the connection stability between the connecting block 4 and the moving slide plate 3.

[0036] The first assembly hole 421 is provided through the connecting block 4. The through first assembly hole 421 can provide a connection position for the assembly, so that the connecting block 4 and the movable slide plate 3 can be connected, thereby improving the assembly accuracy.

[0037] The working principle of this utility model is as follows: During assembly, the groove 41 and the protrusion can be more easily aligned and installed, reducing adjustment time, improving assembly efficiency, and better ensuring the coaxiality of the movable slide plate 3 and the connecting block 4, ensuring that the movable slide plate 3 and the connecting block 4 maintain a consistent motion trajectory during the movement.

[0038] Furthermore, the connecting block 4 is provided with a first mounting hole 421 and an assembly part on both sides. The assembly part can be a bolt. The movable slide plate 3 is provided with a second mounting hole corresponding to the position of the first mounting hole 421. The assembly part passes through the first mounting hole 421 and connects with the second mounting hole, which can effectively prevent the connecting block 4 and the movable slide plate 3 from loosening or falling off. The fastening effect of the assembly part can further ensure that the connecting block 4 and the movable slide plate 3 remain coaxial in the radial direction, thereby achieving coaxial alignment between the connecting block 4 and the movable slide plate 3.

[0039] The fastening bolt can further enhance the stability of the connection between the fastening screw and the connecting block 4. The output shaft of the drive cylinder 11 passes through the through hole and is connected to the fastening screw. This ensures that the output shaft of the drive cylinder 11 is transmitted to the connecting block 4 through the fastening screw, reducing errors in the intermediate links, and at the same time avoiding direct connection between the output shaft of the drive cylinder 11 and the connecting block 4, which would cause wear to the connecting block 4.
