It should be noted that, in the case of no conflict, the embodiments of the present application and the features in the embodiments may be combined with each other. For convenience of description, the words "upper", "lower", "left" and "right" are merely used herein to denote a correspondence with the upper, lower, left, and right directions of the drawing figures, and are not limiting on the structure.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced otherwise than as described herein, and therefore the present invention is not limited to the specific embodiments of the disclosure that follow.
As shown in fig. 1 to 13, the low-pressure casting device with automatic pick-and-place function provided by the invention comprises a low-pressure casting machine 1, wherein the low-pressure casting machine 1 comprises a frame 11, an upper die seat 12 and a lower die seat 13, a hydraulic driving device 14 connected with the frame 11 is arranged above the upper die seat 12, and a casting liquid supply and pressure system 15 for supplying casting liquid to an upper die and a lower die is arranged below the lower die seat 13. The frame 11, the upper mold base 12, the lower mold base 13, the hydraulic driving device 14, and the casting solution supply and pressure system 15 are well known in the art, and the description of this embodiment is omitted herein. On the basis, the invention is provided with the mounting frames 2 on both sides of the frame 11, wherein the mounting frames 2 on one side are provided with the fence ladder 3, and the fence ladder 3 plays a role in safety protection on one hand and can be used for overhauling and other daily operations by workers on the other hand.
Further, the invention is provided with the unpowered manipulator 4 on the mounting frame 2 at the other side of the equipment, the unpowered manipulator 4 comprises a main shaft 41 fixedly connected with the mounting frame 2, a telescopic arm 42 connected with the upper die seat 12 is rotatably arranged on the main shaft 41, a bucket-type unloading arm 43 rotatably connected with the telescopic arm 42 is arranged below the telescopic arm 42, one end of the bucket-type unloading arm 43 is connected with a supporting arm 44 arranged at the end part of the main shaft 41, the other end of the bucket-type unloading arm 43 is pulled up by the upper die seat 12 along with the hydraulic driving device 14 to turn over towards the lower part of the upper die seat 12, and the bucket-type unloading arm 43 is used for receiving castings and guiding the castings out along the inclined direction of the castings. The unpowered manipulator 4 has no independent power system and control system, but can be folded and unfolded along with the expansion and contraction of the hydraulic driving device 14, if the hydraulic driving device 14 drives the upper die seat 12 to descend, the telescopic arm 42 can stretch while overturning, and the bucket-type unloading arm 43 is involved in overturning, and the unpowered manipulator 4 is in an unfolded state, in which the working surface of the bucket-type unloading arm 43 does not interfere with the die closing and low-pressure casting processes of the upper die seat 12 and the lower die seat 13; conversely, in the process of the hydraulic driving device 14 driving the upper die holder 12 to ascend, the bucket type discharging arm 43 and the telescopic arm 42 are turned over simultaneously, the length of the telescopic arm 42 is shortened to ensure that the ascending stroke of the upper die holder 12 can be completed smoothly, and the bucket type discharging arm 43 just supports the casting while the ascending stroke of the upper die holder 12 is completed and the casting is released, and the casting moves downwards along the bucket type discharging arm 43 under the action of inertia and gravity of the casting until the casting gradually and automatically falls on the feeding equipment. In this way, the unpowered manipulator 4 adopts a mode of being linked with the hydraulic driving device 14, so that the purposes of saving equipment cost and space cost are achieved, the design is reasonable, the space utilization rate is improved, and the device is suitable for large-scale popularization.
Because the movable center of the unpowered manipulator 4 is the main shaft 41, and the main shaft 41 is based on the mounting frame 2, in consideration of the limited movable space of the unpowered manipulator 4, especially the limited connection range with the upper die holder 12, in order to improve the working performance of the unpowered manipulator 4, the telescopic arm 42 provided by the invention comprises a shaft sleeve 421, one side of the shaft sleeve 421 is provided with a pair of first fixed length sections 422 hinged with the bucket-type unloading arm 43, the other side of the shaft sleeve 421 is provided with a pair of second fixed length sections 423 in an inverted V shape with the first fixed length sections 422, the second fixed length sections 423 are provided with sliding grooves 424 and adjusting holes 425 communicated with the sliding grooves 424, the sliding grooves 424 are provided with telescopic sections 426, the telescopic sections 426 are provided with guide members 427 in sliding fit with the adjusting holes 425, the tail ends of the telescopic sections 426 are provided with folding sections 428 in rotary connection with the telescopic sections, one side of the upper die holder 12 is provided with two hinge supports 5, and the two hinge supports 5 are correspondingly hinged with different folding sections 428. The sleeve 421 provides high torsional strength and compressive strength for the telescopic arm 42; the first fixed length section 422 and the second fixed length section 423 respectively play a role of connecting the bucket-type unloading arm 43 and the telescopic section 426, and particularly the telescopic section 426 can stretch out and draw back along the sliding groove 424, and the folding section 428, the telescopic section 426 and the hinge support 5 can be folded, so that the actual lengths of the second fixed length section 423, the telescopic section 426, the folding section 428 and the hinge support 5 can stretch out and draw back along with the lifting of the upper die holder 12, the maximum real-time length of the second fixed length section 423 can meet the requirement that the upper die holder 12 and the lower die holder 13 are completely clamped, and the shortest real-time length of the telescopic arm 42 can ensure that the upper die holder 12 returns to an uplink stop point. The guide 427 enables the telescoping segment 426 to move in a directional manner along the chute 424, thereby ensuring smoothness and stability of the telescoping arm 42 during telescoping motion. The guide 427 may be a screw, nut combination or a slider.
Considering that the discharging width of the bucket type discharging arm 43 must be greater than the maximum width of the upper die holder 12 and the castings, and in order to ensure that the telescopic arm 42 and the bucket type discharging arm 43 have good balance performance, the front-rear span of the telescopic arm 42 in the invention is relatively large, and on the basis, in order to ensure that the wider telescopic arm 42 is always connected with the upper die holder 12, the second fixed length section 423, the telescopic section 426 and the folding section 428 incline towards the center of the upper die holder 12, and the two hinged supports 5 slide in opposite directions along with the lifting action of the upper die holder 12 and the telescopic action of the telescopic arm 42. In this way, the telescopic arm 42 maintains a larger front-rear span, and performs reasonable self-adaptive adjustment with the hinge supports 5 while the telescopic span is changed, the upper die holder 12 descends, the included angle of the telescopic arm 42 in the telescopic direction is reduced, and correspondingly, the two hinge supports 5 move towards each other to reduce the distance between the two hinge supports; on the contrary, the upper die holder 12 is lifted, the included angle of the telescopic arm 42 in the telescopic direction is increased, and accordingly, the two hinge supports 5 move oppositely to widen the distance between the two hinge supports, so that the telescopic arm 42 and the upper die holder 12 are ensured to always maintain a stable and reliable connection relationship.
In order to improve the unloading performance of the unpowered manipulator 4, the bucket type unloading arm 43 provided by the invention comprises a pair of V-shaped guard plates 431, wherein the openings of the guard plates 431 are obtuse angles, a slope bucket 432 is arranged between the guard plates 431, the top end, the left end and the right end of the slope bucket 432 are all open, and the depth of the slope bucket 432 gradually becomes deeper from one end of the slope bucket 432 close to an upper die to the other end of the slope bucket 432, and the width of the slope bucket 432 gradually becomes narrower. In this way, the bucket-type unloading arm 43 can drop from the slope bucket 432 after supporting the castings along with the rising of the upper die holder 12, and gradually goes deep in the automatic falling process, so that the castings cannot jump out of two sides of the guard plates 431, a relatively determined direction can be obtained, and the castings can fall on the feeding equipment better, particularly when the same die is cast into a plurality of castings, the effect of arrangement is achieved, and the castings are guided out orderly.
Further, in order to improve the discharging efficiency of the castings, a row of guide rollers 433 are arranged on two sides of the slope bucket 432, the rolling surface of each guide roller 433 faces the center line of the slope bucket 432, the bottom surface of the slope bucket 432 is an arc slope surface, a supporting opening 434 is formed in the center of the slope bucket 432, and a plurality of supporting rollers 435 distributed along the length direction of the supporting opening 434 are arranged in the supporting opening 434. In this way, the friction between the casting and the slope bucket wall can be reduced, and the discharging efficiency of the casting is improved. The design of the cambered surface adopted at the bottom of the slope bucket 432 can reduce the actual contact area between the casting and the bottom surface of the slope bucket 432, is beneficial to heat dissipation, and can reduce the design duty cycle volume and the total mass of the unpowered manipulator 4 and reduce the work load of the hydraulic driving device 14.
