Description

Technical Field

[0001] The invention relates to the technical field of die casting moulds, in particular to a die casting mould frame for a landing gear strut which is easy to disassemble. Background Art

[0002] The landing gear strut is responsible for the transmission of static and dynamic loads of the aircraft. It is the "leg" of the aircraft, used to support the weight of the aircraft on the ground, and participates in a series of actions and movements when the aircraft takes off and lands. The landing gear strut is a key component in the landing gear system, and together with other components such as shock absorbers, mechanical transmission mechanisms, wheels (including brakes), etc., it constitutes a complete landing gear system. According to the different forms and structures of the landing gear, the landing gear strut can have different combinations and functions. The landing gear strut is usually die-casted by a die-casting mold. Die-casting is a metal casting process. Under the action of high pressure, liquid or semi-liquid metal is filled into the die-casting mold, and solidified under pressure by a die-casting machine, so as to obtain a die-casting with a clear outline and smooth surface. In order to produce different types of landing gear struts, different die-casting cores need to be replaced for manufacturing. However, the disassembly and installation of the fixed core and the movable core in the existing die-casting mold frame need to be carried out separately. For example, the movable core needs to be manually lifted mechanically and aligned and embedded in the movable mold. Then, the movable core and the movable mold are fixed using a positioning assembly. Therefore, each time a different core is replaced in the mold frame, it takes a long time and labor, resulting in low die-casting efficiency in product production. Summary of the invention

[0003] The object of the present invention is to provide a landing gear strut die-casting mold frame that is easy to disassemble, so as to solve the problems raised in the above-mentioned background technology.

[0007] Furthermore, an upper mold core is slidably embedded in the upper mold frame, a casting port is provided at the center position of the upper mold frame and the upper mold core, two T-slots are symmetrically provided in the upper mold core, two L-shaped plates are symmetrically slidably clamped in the T-slots, the ends of the two L-shaped plates are fixedly connected with inclined slide frames, displacement plates are externally sleeved on the two L-shaped plates, positioning columns slidably connected to the side walls of the displacement plates are fixedly connected, and two tension springs fixedly connected to the L-shaped plates are symmetrically sleeved on the outside of the positioning columns.

[0008] Furthermore, the fixed mold positioning mechanism includes a lower mold core that is slidably embedded in the lower mold frame, and bosses are fixedly connected to the opposite side walls of the lower mold core. Two clamping grooves are symmetrically provided in the lower mold core, and a clamping plate is slidably clamped in the clamping groove. A trapezoidal slide plate is fixedly connected to the end of the clamping plate, and the trapezoidal block is slidably clamped to the trapezoidal slide plate.

[0009] Furthermore, two fixing rods are slidably sleeved in the clamping plate, a connecting plate is fixedly connected between the bottom ends of the two fixing rods, and a return spring is sleeved on the outside of the two fixing rods, and the bottom end of the return spring is fixedly connected to the clamping plate.

[0011] Furthermore, four guide rods are symmetrically fixedly connected to the bottom of the upper mold core, and four guide holes for slidingly plugging with the guide rods are opened on the top of the lower mold core.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The hydraulic oil in the frame tube, telescopic rod 1 and telescopic rod 2 is pumped into the oil storage tank through the hydraulic pump. Under the action of the negative pressure of the liquid, the telescopic rod 1 and telescopic rod 2 are driven to shrink, so that the driving part drives the two inclined slide frames and the L-shaped plate to move outward, so that the L-shaped plate moves out of the T-slot. At the same time, the displacement plate will also drive the two positioning rods 1 to move out of the upper mold core, so that the upper mold core is no longer positioned between the upper mold frame. Then, the hydraulic cylinder 1 is used to drive the upper mold frame to rise and separate from the upper mold core. The two ends of the telescopic rods will drive the traction rope to move, and the other end of the traction rope drives the trapezoidal block to slide on the fixed column. The trapezoidal block can drive the trapezoidal slide plate and the clamping plate to move out of the clamping groove. Similarly, the connecting plate will drive the positioning rod 2 to move out of the lower mold core, so that the limit between the lower mold core and the lower mold frame is lost. Then the two hydraulic cylinders extend and drive the lifting plate to rise to lift the bosses on the opposite sides of the lower mold core, thereby lifting the lower mold core out of the lower mold frame. After that, the linear motor drives the frame and the disassembled lower mold core and upper mold core to move out from the position of the lower mold frame. By simultaneously canceling the limit of the upper mold core and the lower mold core, and then using the lifting plate to take out the disassembled mold core, the disassembly efficiency of the mold core is improved.

[0015] 2. After the new lower mold core is moved to the position of the lower mold frame, the hydraulic cylinder 2 contracts and drives the lower mold core to slide and embed into the lower mold frame, and then the upper mold frame is driven down by the hydraulic cylinder 1 to embed with the upper mold core, and then the hydraulic oil in the oil storage tank is pumped into the frame tube, telescopic rod 1 and telescopic rod 2 by the hydraulic pump, so that the telescopic rod 1 drives the driving part to push the inclined slide frame to move, so that it drives the L-shaped plate to be inserted into the T-slot, and the positioning rod 1 is inserted into the upper mold core. At the same time, after the two telescopic rods 2 are extended, the extrusion spring will squeeze the trapezoidal block to move, and the trapezoidal block drives the trapezoidal slide plate to move, so that the clamping plate is inserted into the clamping groove, and then the upper mold frame and the upper mold core are driven to rise by the hydraulic cylinder 1, so that the inclined slide frame and the driving part gradually slide. Separation, under the pull of the tension spring, the L-shaped plate is driven to remain engaged with the T-slot in the upper mold core, so the upper mold core and the upper mold frame can be quickly positioned and installed, and then the linear motor drives the frame to move away from the position of the lower mold frame. In this process, the trapezoidal block and the trapezoidal slide plate slide apart, and the clamping plate rises under the action of the reset spring and remains embedded in the clamping groove. Therefore, the lower mold core and the lower mold frame are positioned and installed, so that the upper mold core and the lower mold core can be installed at the same time, without relying on manual or mechanical lifting of the upper mold core to the position of the upper mold frame and then fixing the installation assembly, thereby avoiding injuries caused by the mold core falling. Quick completion of the installation of the mold core can enable the die-casting machine to quickly put into the production of new landing gear struts. BRIEF DESCRIPTION OF THE DRAWINGS

The disassembly lifting mechanism 400 includes a frame 401, and two supporting frames 402 are symmetrically fixedly connected to the inner side wall of the frame 401. The bottoms of the two supporting frames 402 are fixedly connected to hydraulic cylinders 404, and the tops of the two hydraulic cylinders 404 are fixedly connected to lifting plates 405. The bottom of the frame 401 Two linear motors 403 are symmetrically fixedly arranged, and a telescopic rod 414 is fixedly connected to the bottom of the frame 401, and one end of a traction rope 415 is fixedly connected to the end of the telescopic rod 414, and a trapezoidal block 416 is fixedly connected to the other end of the traction rope 415. A fixed column 417 fixedly connected to the frame 401 is slidably sleeved on the top of the trapezoidal block 416, and a fixed pulley 419 is rotatably connected to the bottom of the fixed column 417, and the traction rope 415 is wound around the fixed pulley 419. An extrusion spring 418 fixedly connected to the trapezoidal block 416 is fixedly connected to the inner wall of the fixed column 417, driving the two trapezoidal blocks 416 and the trapezoidal slide plate 305 on the same side to slide and contact each other until the bottom surface of the trapezoidal block 416 completely coincides with the inner top surface of the trapezoidal slide plate 305, at which time the trapezoidal block 416 and the trapezoidal slide plate 305 remain engaged. The frame 401 is fixedly connected to the outside with a frame-shaped tube 407, the end of the telescopic rod 2 414 is fixedly connected to the frame-shaped tube 407, the bottom of the frame-shaped tube 407 is fixedly connected to a connecting tube 411 connected to the inside thereof, the bottom of the connecting tube 411 is fixedly connected to the output end of a hydraulic pump 412, the input end of the hydraulic pump 412 is fixedly connected to an oil storage tank 413, and the outside of the oil storage tank 413 is fixedly sleeved with a ferrule frame 406. The frame 401 is symmetrically fixedly connected to two connecting frames 408, and the two connecting frames 408 are fixedly connected to a telescopic rod 1 409, the end of the telescopic rod 1 409 is fixedly connected to the frame-shaped tube 407, and the other end of the telescopic rod 1 409 is fixedly connected to a driving member 410, and the driving member 410 is slidably engaged with the inclined slide frame 209.

[0020] Specifically, when replacing a new mold core for the die-casting mold frame, the two linear motors 403 are first used to drive the disassembly lifting mechanism 400 to move on the two slide rails 102 toward the lower mold frame 101. In this process, the two trapezoidal blocks 416 and the trapezoidal slide plate 305 on the same side can be driven to slide against each other until the bottom surface of the trapezoidal block 416 completely coincides with the inner top surface of the trapezoidal slide plate 305. At this time, the trapezoidal block 416 and the trapezoidal slide plate 305 remain engaged, so that the trapezoidal slide plate 305 can drive the end of the clamping plate 306 to move downward from the vertical groove of the clamping groove 304 and reset it. The spring 310 is stretched, and then extended by the hydraulic cylinder 106 to drive the upper mold frame 201 to descend along the limit rod 104, thereby driving the four guide rods 204 at the bottom of the upper mold core 203 to be inserted into the guide hole 302 at the top of the lower mold frame 301 and complete the merging. When the upper mold frame 201 descends, it will drive the inclined slide groove frames 209 on both sides to descend synchronously, and the inclined slide groove frames 209 and the driving member 410 slide against each other, thereby squeezing the two L-shaped plates 207 to slide relative to each other. When the mold cores are merged, the side walls of the two L-shaped plates 207 are pressed against each other, so that the L-shaped plates 207 can be moved out from the inside of the T-slot 206; Afterwards, the hydraulic oil in the frame tube 407, telescopic rod 1 409 and telescopic rod 2 414 is pumped into the oil storage tank 413 through the hydraulic pump 412, and the telescopic rod 1 409 and telescopic rod 2 414 are driven to shrink under the action of the liquid negative pressure, so that the driving member 410 drives the two inclined slide frames 209 and the L-shaped plate 207 to move outward, so that the L-shaped plate 207 is moved out of the T-slot 206, and at the same time, the displacement plate 208 will also drive the two positioning rods 1 212 to move out of the upper mold core 203, so that the upper mold core 203 is no longer positioned between the upper mold frame 201, and then the hydraulic cylinder 106 is used to drive the upper mold frame 201 to rise and separate from the upper mold core 203, and the end of the telescopic rod 214 will drive the pulling rope 415 to move, and the other end of the pulling rope 415 drives the trapezoidal block 416 on the fixed column 417 The sliding of the trapezoidal block 416 can drive the trapezoidal slide plate 305 and the clamping plate 306 to move out of the clamping groove 304. Similarly, the connecting plate 307 will drive the positioning rod 2 308 to move out of the lower mold core 301, so that the limit between the lower mold core 301 and the lower mold frame 101 is lost. Then the two hydraulic cylinders 2 404 extend to drive the lifting plate 405 to rise to lift the bosses 303 on the opposite sides of the lower mold core 301, thereby lifting the lower mold core 301 out of the lower mold frame 101. After that, the linear motor 403 drives the frame 401 and the disassembled lower mold core 301 and the upper mold core 203 to move out from the position of the lower mold frame 101. By simultaneously canceling the limit of the upper mold core 203 and the lower mold core 301, and then using the lifting plate 405 to take out the disassembled mold core, the disassembly efficiency of the mold core is improved.

[0023] During the specific implementation, the new upper mold core 203 and the lower mold core 301 are combined and placed between the two lifting plates 405, and then the new lower mold core 301 is moved to the position of the lower mold frame 101, and the hydraulic cylinder 2 404 contracts to drive the lower mold core 301 to slide and embed into the lower mold frame 101, and then the upper mold frame 201 is driven down by the hydraulic cylinder 1 106 to embed with the upper mold core 203, and then the hydraulic oil in the oil storage tank 413 is pumped into the frame tube 407, the telescopic rod 1 409 and the telescopic rod 2 414 through the hydraulic pump 412, so that the telescopic rod 1 409 drives the driving member 410 to push the inclined slide frame 209 to move, so that it drives the L-shaped plate 207 to be inserted into In the T-slot 206, the positioning rod 212 is inserted into the upper mold core 203.
