Description

Technical Field

[0001] This utility model relates to the field of mold slide structure technology, and in particular to a slide structure with pre-pull-out function. Background Technology

[0002] The automotive structural components of the WAYMO series are undoubtedly extremely complex, posing unprecedented challenges to the design of die-casting molds. The complex product structure necessitates a slider-type design to address the difficulties in critical areas.

[0003] Complex products generate enormous clamping forces during demolding. The force exerted by the hydraulic cylinder is insufficient to allow the slide to disengage perfectly, which may cause problems such as jamming of the slide or the product during production. A single hydraulic cylinder slide mechanism can no longer meet the basic conditions for smooth demolding. Utility Model Content

[0004] The purpose of this invention is to provide a sliding structure with a pre-pull-out function to address the shortcomings of existing technologies.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A sliding structure with pre-draft function includes a sliding guide rail and a sliding slider slidably mounted on the sliding guide rail. A telescopic cylinder is provided at the outer end of the sliding guide rail, and the driving end of the telescopic cylinder is connected to the sliding slider. A forming structure is provided at the inner end of the sliding slider. The sliding slider is formed with a draft groove, which is inclinedly recessed into the sliding slider. An ejector wedge is installed in the draft groove, and the ejector wedge can move longitudinally to drive the sliding slider to move along the sliding guide rail.

[0007] Furthermore: the guide rail includes a pair of parallel spaced guide rail plates, and the sliding slider is disposed between the two guide rail plates, and the sliding slider can move along the length direction of the two guide rail plates.

[0008] Furthermore: the bottom of the sliding slider is formed with a bottom plate, and the bottom of the inner side of the guide rail plate is formed with a bottom groove along the length direction, and the bottom plate and the bottom groove slide together.

[0009] Furthermore: a connecting plate is provided between the sliding guide rail and the telescopic cylinder. The connecting plate is located outside the guide rail plate, and a cylinder seat is connected to the inner end of the connecting plate. The body of the telescopic cylinder is installed on the cylinder seat, and the cylinder seat is formed with a movable hole for the piston rod of the telescopic cylinder to pass through.

[0010] Furthermore: the inner end of the sliding slider is formed with a T-groove, and the outer end of the piston rod is fitted with a T-block that is engaged and connected with the T-groove.

[0011] Furthermore: the cylinder seat is movably mounted with a guide rod parallel to the piston rod, and the cylinder seat has a guide hole for the guide rod to slide, and the outer end of the guide rod is connected to the sliding slider.

[0012] Furthermore: the other end of the guide rod is formed with an external thread structure, and a limit sleeve is installed on the guide rod through the external thread structure. A compression spring sleeved on the guide rod is provided between the limit sleeve and the cylinder seat.

[0013] Furthermore, the cylinder seat is also slidably mounted with a detection rod and a guide seat for guiding the detection rod to slide. The guide seat has a bottom hole for the detection rod to slide through. A fixing sleeve is fitted on the outer end of the piston rod, and the outer end of the detection rod is connected to the fixing sleeve.

[0014] Furthermore, the cylinder seat is also provided with a first distance sensor and a second distance sensor arranged at intervals, and a sensing block that cooperates with the first distance sensor and the second distance sensor is installed at the inner end of the detection rod.

[0015] Furthermore: an inclined sliding block is installed in the draft groove, and the ejector sliding block and the sliding sliding block are in sliding engagement.

[0016] The beneficial effects of this utility model are as follows: After the mold is closed, the ejector inclined block is installed in the draft groove. At this time, the ejector inclined block can fix the slide block, and the slide block will not move laterally, which can play a positioning and limiting role. After the product is formed in the mold, when demolding is required, the forming structure of the slide block and the product will stick together, which will generate a huge clamping force. At this time, the ejector inclined block can be pulled out longitudinally. The ejector inclined block will slide and cooperate with the inclined surface of the draft groove. At this time, the slide block will move laterally a part. At this time, there will be loosening between the forming structure of the slide block and the product. At this time, the telescopic cylinder located outside the slide guide can retract, which can drive the slide block to retract along the slide guide. This fully solves the difficulty of demolding with large clamping force, ensures that the product can be demolded smoothly, and paves the way for subsequent mass production.

[0029] The present invention will now be described in detail with reference to the accompanying drawings.

[0030] like Figure 1-2 As shown, a sliding structure with pre-draft function includes a sliding guide rail 11 and a sliding slider 1 slidably mounted on the sliding guide rail 11. A telescopic cylinder 20 is provided at the outer end of the sliding guide rail 11, and the driving end of the telescopic cylinder 20 is connected to the sliding slider 1. A forming structure 18 is provided at the inner end of the sliding slider 1. The sliding slider 1 is formed with a draft groove 15, which is inclinedly recessed in the sliding slider 1. An ejector slant block 16 is installed in the draft groove 15, and the ejector slant block 16 can move longitudinally to drive the sliding slider 1 to move along the sliding guide rail 11.

[0031] After mold closing, the ejector slant block 16 is installed into the draft groove 15. At this time, the ejector slant block 16 can fix the slide block 1, and the slide block 1 will not move laterally, which can play a positioning and limiting role. After the product in the mold is formed, when demolding is required, the forming structure 18 of the slide block 1 will stick to the product, generating a huge clamping force. At this time, the ejector slant block 16 can be pulled out longitudinally, and the ejector slant block 16 will slide and cooperate with the inclined surface of the draft groove 15. At this time, the slide block 1 will move laterally a part. At this time, there will be loosening between the forming structure 18 of the slide block 1 and the product. At this time, the telescopic cylinder 20 located outside the slide guide rail 11 can retract, which can drive the slide block 1 to retract along the slide guide rail 11. This fully solves the difficulty of demolding due to large clamping force, ensures that the product can be demolded smoothly, and paves the way for subsequent mass production.

[0032] Specifically, in one embodiment, an inclined sliding block 17 is installed in the draft groove 15. An ejector block 16 slides in conjunction with the sliding block 17. The inclined angle of the ejector block 16 is 8°, which converts 14% of the mold opening force into a sliding block demolding force, ejecting the sliding block approximately 10mm away from the maximum clamping force area. During demolding, the sliding block 17 contacts the ejector block 16. The sliding block 17 receives the ejection force of the ejector block 16 and moves relative to it along the inclined surface, thereby disengaging the sliding block 1.

[0033] Specifically, the sliding guide rail 11 includes a pair of parallel and spaced guide rail plates 12, and the sliding slider 1 is disposed between the two guide rail plates 12. The sliding slider 1 can move along the length direction of the two guide rail plates 12. The bottom of the sliding slider 1 is formed with a bottom plate 13, and the bottom inner side of the guide rail plate 12 is formed with a bottom groove 14 along the length direction. The bottom plate 13 and the bottom groove 14 are slidably engaged. When the sliding slider 1 moves, the bottom plate 13 at the bottom of the sliding slider 1 will slide and engage with the bottom groove 14 at the bottom of the guide rail plate 12, which has the effect of limiting the sliding, ensuring that the molding structure 18 can move to the designated position after the sliding slider 1 is closed, and the molding accuracy can be effectively guaranteed.

[0034] Furthermore, a connecting plate 19 is provided between the sliding guide rail 11 and the telescopic cylinder 20. The sliding guide rail 11 can be fixed by the connecting plate 19. The connecting plate 19 is located outside the guide rail plate 12, and the inner end of the connecting plate 19 is connected to the cylinder seat 2. The body of the telescopic cylinder 20 is installed on the cylinder seat 2. The cylinder seat 2 is formed with a movable hole 21 for the piston rod 22 of the telescopic cylinder 20 to pass through. The inner end of the sliding block 1 is formed with a T-slot 24, and the outer end of the piston rod 22 is installed with a T-block 23 that fits into the T-slot 24. The telescopic cylinder 20 installed on the cylinder seat 2 connects to the sliding block 1 after the piston rod 22 passes through the movable hole 21. Since the end of the piston rod 22 is equipped with a T-block 23, and the sliding block 1 is formed with a T-slot 24 that mates with the T-block 23, the T-block 23 can be installed with the T-slot 24 by fitting, which allows for detachable connection and facilitates subsequent maintenance.

[0035] The cylinder seat 2 is movably mounted with a guide rod 25 parallel to the piston rod 22. The cylinder seat 2 has a guide hole 26 for the guide rod 25 to slide. The outer end of the guide rod 25 is connected to the sliding block 1. When the piston rod 22 moves, the guide rod 25 moves synchronously. The guide rod 25 slides with the guide hole 26, which has a certain guiding effect. The sliding block 1 can move linearly to ensure that the forming structure 18 set on the sliding block 1 moves into place.

[0036] Furthermore, the other end of the guide rod 25 is formed with an external thread structure 27. The guide rod 25 is fitted with a limiting sleeve 28 through the external thread structure 27. A compression spring 29 is sleeved on the guide rod 25 between the limiting sleeve 28 and the cylinder seat 2. After the mold is closed, the elastic force of the compression spring 29 will drive the guide rod 25 outward to have a buffering effect. When the slide block 1 moves, the elastic force of the compression spring 29 will produce a corresponding buffering effect to reduce the vibration caused by the collision. In addition, since the limiting sleeve 28 is threadedly engaged with the external thread structure 27 of the guide rod 25, the limiting sleeve 28 can be rotated to adjust its axial position, thereby adjusting the elastic force of the compression spring 29.

[0037] The cylinder seat 2 also slidably mounts a detection rod 31 and a guide seat 3 for guiding the detection rod 31 to slide. The guide seat 3 has a bottom hole 32 for the detection rod 31 to slide through. A fixed sleeve 33 is fitted onto the outer end of the piston rod 22, and the outer end of the detection rod 31 is connected to the fixed sleeve 33. The cylinder seat 2 is also provided with a first distance sensor 34 and a second distance sensor 35 arranged at intervals. A sensing block 36 that senses and cooperates with the first distance sensor 34 and the second distance sensor 35 is installed on the inner end of the detection rod 31. The first distance sensor 34 and the second distance sensor 35 are both infrared distance sensors. When the sliding block 1 is in mold closing and demolding, it will move between two points. At the same time, the detection rod 31 slides along the fixed sleeve 33. When the mold is closed, the sensing block 36 at the inner end of the detection rod 31 is in contact with the second distance sensor 35, and a signal indicating that the mold is closed is output to the signal receiving device. Conversely, when the mold is demolded, the sensing block 36 at the inner end of the detection rod 31 is in contact with the first distance sensor 34, and a signal indicating that the mold is demolded is output to the signal receiving device.

[0038] In summary, this utility model possesses the aforementioned excellent characteristics, enabling it to achieve unprecedented efficiency in use and thus become a highly practical product.
