Abstract

The present invention relates to the technical field of die-casting molds, and specifically to a die-casting mold base for a landing gear strut that is convenient for disassembly, including a disassembly and lifting mechanism, which is used to disassemble and remove the moving die core and the fixed die core or replace the new die core and install it. In the present invention, the hydraulic cylinder 1 is used to drive the upper mold base to rise and separate from the upper die core. The end of the telescopic rod 2 will drive the pulling traction rope to move, and the trapezoidal block can drive the trapezoidal chute 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 die core. Therefore, the lower die core and the lower mold base lose their limit. Then, the two hydraulic cylinders 2 extend to drive the lifting plate to rise and lift the bosses on the relative two sides of the lower die core. After that, the linear motor drives the frame and the disassembled lower die core and upper die core to move out from the position of the lower mold base. By simultaneously canceling the limit of the upper die core and the lower die core, and then using the lifting plate to take out the disassembled die core, the disassembly efficiency of the die core of the mold is improved.

Description

Technical Field

[0001] The present invention relates to the technical field of die-casting molds, and specifically to a die-casting mold base for a landing gear strut that is easy to disassemble. Background Art

[0002] The landing gear strut bears the transfer 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 is also involved in a series of actions and movements during takeoff and landing of the aircraft. 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, and wheels (including braking devices), it constitutes a complete landing gear system. Depending on the different forms and structures of the landing gear, the landing gear strut can have different combination methods and functions. The landing gear strut is usually die-cast by a die-casting mold. Die-casting is a metal casting process in which, under high pressure, liquid or semi-liquid metal is filled into the die-casting mold and solidified under pressure by a die-casting machine, thus obtaining die-castings with clear contours and smooth surfaces. In order to produce different types of landing gear struts, it is necessary to manufacture them by replacing different die-casting cores. However, in the existing die-casting mold bases, the disassembly and installation of the fixed die core and the moving die core need to be carried out separately. For example, the moving die core needs to be manually lifted by machinery and aligned and inserted into the moving mold, and then the moving die core and the moving mold are fixed using positioning components. Therefore, each time a different die core is replaced in the mold base, it takes a long time and a lot of labor, resulting in a low die-casting efficiency for product production. Summary of the Invention

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

[0004] To achieve the above purpose, the present invention provides the following technical solutions:

[0006] A support mechanism, which is used to support the entire die-casting mold;

[0007] A moving mold positioning mechanism, which is used to position the upper die core and the upper mold base;

[0008] A fixed mold positioning mechanism, which is used to fix the lower die core and the lower mold base;

[0009] Demolition and lifting mechanism, the demolition and lifting mechanism is used to disassemble and remove the upper die core and the lower die core or replace the new die core and install it. The demolition and lifting mechanism includes a frame body. On the inner side walls of the frame body, two support frames are symmetrically and fixedly connected. At the bottoms of the two support frames, two hydraulic cylinders II are fixedly connected. At the tops of the two hydraulic cylinders II, lifting plates are fixedly connected. At the bottom of the frame body, two linear motors are symmetrically and fixedly arranged. At the bottom of the frame body, a telescopic rod II is fixedly connected. One end of a traction rope is fixedly connected to the end of the telescopic rod II. The other end of the traction rope is fixedly connected to a trapezoidal block. The top of the trapezoidal block is slidably sleeved with a fixed column fixedly connected to the frame body. At the bottom of the fixed column, a fixed pulley is rotatably connected. The traction rope is wound around the fixed pulley. On the inner side wall of the fixed column, a compression spring fixedly connected to the trapezoidal block is fixedly connected.

[0010] Furthermore, the support mechanism includes a lower die holder. On the opposite side walls of the lower die holder, slide rail plates are fixedly connected. The linear motors are slidably connected to the slide rail plates. At the bottoms of the two slide rail plates, inclined support plates fixedly connected to the lower die holder are fixedly connected.

[0011] Furthermore, the moving die positioning mechanism includes an upper die holder. On the opposite side walls of the upper die holder, two sliding plates are symmetrically and fixedly connected. In the four sliding plates, limiting rods are slidably sleeved. The bottom ends of the limiting rods are fixedly connected to the lower die holder. Between the top ends of the four limiting rods, a top plate is fixedly connected. At the bottom of the top plate, two hydraulic cylinders I are symmetrically and fixedly connected. The hydraulic cylinders I are fixedly connected to the upper die holder.

[0012] Furthermore, an upper die core is slidably embedded in the upper die holder. At the central positions of the upper die holder and the upper die core, a pouring port is opened. In the upper die core, two T-shaped grooves are symmetrically opened. In the T-shaped grooves, two L-shaped plates are symmetrically and slidably clamped. At the ends of the two L-shaped plates, inclined surface chute frames are fixedly connected. An offset plate is sleeved outside the two L-shaped plates. On the side wall of the offset plate, a positioning column slidably connected to the L-shaped plate is fixedly connected. On the outside of the positioning column, two tension springs fixedly connected to the L-shaped plate are symmetrically sleeved.

[0013] Furthermore, the fixed die positioning mechanism includes a lower die core slidably embedded and connected to the lower die holder. On the opposite side walls of the lower die core, bosses are fixedly connected. In the lower die core, two clamping grooves are symmetrically opened. In the clamping grooves, clamping plates are slidably clamped. At the end of the clamping plate, a trapezoidal chute plate is fixedly connected. The trapezoidal block is slidably clamped with the trapezoidal chute plate.

[0014] Furthermore, two fixed rods are slidably sleeved in the clamping plate. Between the bottom ends of the two fixed rods, a connecting plate is fixedly connected. On the outside of the two fixed rods, return springs are sleeved. The bottom ends of the return springs are fixedly connected to the clamping plate.

[0015] Furthermore, two positioning rods I which are symmetrically and fixedly connected to the side wall of the displacement plate and are slidably inserted into the upper die holder and the upper die core are provided. Two positioning rods II which are symmetrically and fixedly connected to the side wall of the connecting plate and are slidably inserted into the lower die holder and the lower die core are provided. Anti-detachment blocks are fixedly connected to the ends of the positioning rods I and the positioning rods II.

[0016] Furthermore, four guide rods are symmetrically and fixedly connected to the bottom of the upper die core. Four guide holes which are slidably inserted with the guide rods are formed at the top of the lower die core.

[0017] Furthermore, a frame-shaped pipe is fixedly connected to the outside of the frame body. The end of the second telescopic rod is fixedly connected to the frame-shaped pipe. A communicating pipe which is communicated with the inside of the frame-shaped pipe is fixedly connected to the bottom of the frame-shaped pipe. The output end of a hydraulic pump is fixedly connected to the bottom end of the communicating pipe. The input end of the hydraulic pump is fixedly connected to an oil storage tank. A hoop frame is fixedly sleeved outside the oil storage tank.

[0018] Furthermore, two connecting frames are symmetrically and fixedly connected to the frame body. A first telescopic rod is fixedly connected to each of the two connecting frames. The end of the first telescopic rod is fixedly connected to the frame-shaped pipe. The other end of the first telescopic rod is fixedly connected to a driving member. The driving member is slidably clamped with the inclined surface chute frame.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] 1. The hydraulic oil in the frame-shaped pipe, the first telescopic rod and the second telescopic rod is pumped into the oil storage tank by the hydraulic pump. Under the action of liquid negative pressure, the first telescopic rod and the second telescopic rod are driven to contract, so that the driving member drives the two inclined surface chute frames and the L-shaped plate to move outwards, so that the L-shaped plate moves out of the T-shaped groove. At the same time, the displacement plate also drives the two positioning rods I to move out of the upper die core. Thus, the upper die core is no longer positioned between the upper die holder. Then, the first hydraulic cylinder is used to drive the upper die holder to rise and separate from the upper die core. The end of the second telescopic rod drives the pulling traction rope to move, and the other end of the traction rope drives the trapezoidal block to slide on the fixed column, so that the trapezoidal block can drive the trapezoidal chute plate and the clamping plate to move out of the clamping groove. Similarly, the connecting plate drives the positioning rod II to move out of the lower die core. Therefore, the lower die core and the lower die holder lose their limit. Then, the two second hydraulic cylinders extend to drive the lifting plate to rise to lift the convex platforms on the relative two sides of the lower die core, so as to lift the lower die core out of the lower die holder. After that, the linear motor drives the frame body and the removed lower die core and upper die core to move out of the position of the lower die holder. By simultaneously canceling the limit of the upper die core and the lower die core, and then using the lifting plate to take out the removed die core, the disassembly efficiency of the die core of the mold is improved.

[0021] 2. After moving the new lower die core to the position of the lower die carrier, the second hydraulic cylinder contracts to drive the lower die core to slide and embed into the lower die carrier. Then, the first hydraulic cylinder drives the upper die carrier to descend and embed with the upper die core. After that, the hydraulic pump pumps the hydraulic oil in the oil storage tank back into the frame-shaped pipe, the first telescopic rod, and the second telescopic rod. Thus, the first telescopic rod drives the driving part to push the inclined surface chute frame to move, so that it drives the L-shaped plate to insert into the T-shaped groove, and the first positioning rod inserts into the upper die core. At the same time, after the two second telescopic rods extend, the compression spring squeezes the trapezoidal block to move, and the trapezoidal block drives the trapezoidal chute plate to move. Thus, the clamping plate inserts into the clamping groove. Then, the first hydraulic cylinder drives the upper die carrier and the upper die core to rise, so that the inclined surface chute frame and the driving part gradually slide and separate. Under the pulling of the tension spring, it drives the L-shaped plate to remain clamped with the T-shaped groove in the upper die core. Therefore, the upper die core and the upper die carrier can be quickly positioned and installed. Then, the linear motor drives the frame to move away from the position of the lower die carrier. During this process, the trapezoidal block and the trapezoidal chute plate slide and separate, and the clamping plate rises under the action of the return spring and remains inserted and clamped with the clamping groove. Therefore, the lower die core and the lower die carrier are completed with positioning and installation. In this way, the upper die core and the lower die core can be installed simultaneously, without relying on manual or mechanical means to lift the upper die core to the position of the upper die carrier and then fix the installation components. Thus, it can avoid the die core from falling and causing injuries to personnel. The rapid completion of the die core installation can enable the die casting machine to quickly be put into the production of the new landing gear strut. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0035] Please refer to Figures 1-11In an embodiment of the present invention, a die-casting mold base for a landing gear strut that is easy to disassemble includes: a support mechanism 100, a moving die positioning mechanism 200, a fixed die positioning mechanism 300, and a disassembly and lifting mechanism 400. The support mechanism 100 is used to support the entire die-casting mold; the moving die positioning mechanism 200 is used to position the upper die core and the upper mold base; the fixed die positioning mechanism 300 is used to fix the lower die core and the lower mold base; the disassembly and lifting mechanism 400 is used to disassemble and remove the upper die core and the lower die core or replace them with new die cores and install them. The disassembly and lifting mechanism 400 includes a frame body 401. Two support frames 402 are symmetrically and fixedly connected to the inner side wall of the frame body 401. Hydraulic cylinders II 404 are fixedly connected to the bottoms of the two support frames 402. Lifting plates 405 are fixedly connected to the tops of the two hydraulic cylinders II 404. Two linear motors 403 are symmetrically and fixedly arranged at the bottom of the frame body 401. A telescopic rod II 414 is fixedly connected to the bottom of the frame body 401. One end of a traction rope 415 is fixedly connected to the end of the telescopic rod II 414. The other end of the traction rope 415 is fixedly connected to a trapezoidal block 416. The top of the trapezoidal block 416 is slidably sleeved with a fixed column 417 fixedly connected to the frame body 401. A fixed pulley 419 is rotatably connected to the bottom of the fixed column 417. The traction rope 415 is wound around the fixed pulley 419. A compression spring 418 fixedly connected to the trapezoidal block 416 is fixedly connected to the inner side wall of the fixed column 417, driving the two trapezoidal blocks 416 to slide and abut against the trapezoidal chute plates 305 on the same side until the bottom surface of the trapezoidal block 416 completely coincides with the inner top surface of the trapezoidal chute plate 305. At this time, the trapezoidal block 416 and the trapezoidal chute plate 305 are kept engaged. A frame-shaped pipe 407 is fixedly connected to the outside of the frame body 401. The end of the telescopic rod II 414 is fixedly connected to the frame-shaped pipe 407. A communicating pipe 411 communicating with the inside of the frame-shaped pipe 407 is fixedly connected to the bottom of the frame-shaped pipe 407. The output end of a hydraulic pump 412 is fixedly connected to the bottom end of the communicating pipe 411. The input end of the hydraulic pump 412 is fixedly connected to an oil storage tank 413. A hoop frame 406 is fixedly sleeved outside the oil storage tank 413. Two connecting frames 408 are symmetrically and fixedly connected to the frame body 401. A telescopic rod I 409 is fixedly connected to each of the two connecting frames 408. The end of the telescopic rod I 409 is fixedly connected to the frame-shaped pipe 407. The other end of the telescopic rod I 409 is fixedly connected to a driving member 410. The driving member 410 is slidably engaged with an inclined surface chute frame 209.

[0036] Specifically, when replacing the mold core of the die-casting mold with a new one, first, two linear motors 403 drive the disassembly and lifting mechanism 400 to move downward along the two slide rail plates 102 towards the lower mold base 101. During this process, the two trapezoidal blocks 416 can be driven to slide and contact the trapezoidal chute plates 305 on the same side until the bottom surface of the trapezoidal block 416 completely coincides with the inner top surface of the trapezoidal chute plate 305. At this time, the trapezoidal block 416 and the trapezoidal chute plate 305 are kept clamped, so that the trapezoidal chute plate 305 can drive the end of the clamping plate 306 to move downward out of the vertical groove of the clamping groove 304, and the return spring 310 is stretched. Then, the first hydraulic cylinder 106 extends to drive the upper mold base 201 to descend along the limiting rod 104, thereby driving the four guide rods 204 at the bottom of the upper mold core 203 to insert into the guide holes 302 at the top of the lower mold base 301 and complete the combination. When the upper mold base 201 descends, it will drive the inclined chute frames 209 on both sides to descend synchronously. The inclined chute frames 209 slide and contact the driving parts 410, thereby squeezing the two L-shaped plates 207 to slide relatively. When the mold cores are combined, the side walls of the two L-shaped plates 207 are in contact with each other, so that the L-shaped plates 207 can move out of the inner side of the T-shaped groove 206;

[0037] After that, the hydraulic pump 412 pumps the hydraulic oil in the frame-shaped pipe 407, the first telescopic rod 409 and the second telescopic rod 414 into the oil storage tank 413. Under the action of liquid negative pressure, the first telescopic rod 409 and the second telescopic rod 414 are driven to contract, so that the driving part 410 drives the two inclined chute frames 209 and the L-shaped plates 207 to move outward, so that the L-shaped plates 207 move out of the T-shaped groove 206. At the same time, the displacement plate 208 will also drive the two first positioning rods 212 to move out of the upper mold core 203, so that the upper mold core 203 is no longer positioned with the upper mold base 201. Then, the first hydraulic cylinder 106 is used to drive the upper mold base 201 to rise and separate from the upper mold core 203. The end of the second telescopic rod 414 will drive the pulling traction rope 415 to move, and the other end of the traction rope 415 drives the trapezoidal block 416 to slide on the fixed column 417, so that the trapezoidal block 416 can drive the trapezoidal chute plate 305 and the clamping plate 306 to move out of the clamping groove 304. Similarly, the connecting plate 307 will drive the second positioning rod 308 to move out of the lower mold core 301. Therefore, the lower mold core 301 and the lower mold base 101 lose their limits. Then, the two second hydraulic cylinders 404 extend to drive the lifting plate 405 to rise to lift the bosses 303 on the relative two sides of the lower mold core 301, so as to lift the lower mold core 301 out of the lower mold base 101. After that, the linear motor 403 drives the frame 401 and the disassembled lower mold core 301 and upper mold core 203 to move out of the position of the lower mold base 101. By simultaneously canceling the limits 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.

[0038] Embodiment 1

[0039] As shown Figures 4-8 In this embodiment, as shown, the moving die positioning mechanism 200 includes an upper die holder 201. Two sliding plates 202 are symmetrically and fixedly connected to the opposite side walls of the upper die holder 201. A limiting rod 104 is slidably sleeved in each of the four sliding plates 202. The bottom end of the limiting rod 104 is fixedly connected to the lower die holder 101. A top plate 105 is fixedly connected between the top ends of the four limiting rods 104. Two hydraulic cylinders 106 are symmetrically and fixedly connected to the bottom of the top plate 105. The hydraulic cylinders 106 are fixedly connected to the upper die holder 201. An upper die core 203 is slidably embedded in the upper die holder 201. A pouring port 205 is opened at the central positions of the upper die holder 201 and the upper die core 203. Two T-shaped grooves 206 are symmetrically opened in the upper die core 203. Two L-shaped plates 207 are symmetrically and slidably clamped in the T-shaped grooves 206. The ends of the two L-shaped plates 207 are fixedly connected with inclined chute frames 209. A displacement plate 208 is sleeved outside the two L-shaped plates 207. A positioning post 210 slidably connected to the L-shaped plate 207 is fixedly connected to the side wall of the displacement plate 208. Two tension springs 211 fixedly connected to the L-shaped plate 207 are symmetrically sleeved outside the positioning post 210;

[0040] The fixed die positioning mechanism 300 includes a lower die core 301 slidably embedded and connected to the lower die holder 101. Bosses 303 are fixedly connected to the opposite side walls of the lower die core 301. Two clamping grooves 304 are symmetrically opened in the lower die core 301. A clamping plate 306 is slidably clamped in the clamping groove 304. A trapezoidal chute plate 305 is fixedly connected to the end of the clamping plate 306. The trapezoidal block 416 is slidably clamped with the trapezoidal chute plate 305. Two fixing rods 309 are slidably sleeved in the clamping plate 306. A connecting plate 307 is fixedly connected between the bottom ends of the two fixing rods 309. A return spring 310 is sleeved outside each of the two fixing rods 309. The bottom end of the return spring 310 is fixedly connected to the clamping plate 306. Two positioning rods 1 212 slidably inserted into the upper die holder 201 and the upper die core 203 are symmetrically and fixedly connected to the side wall of the displacement plate 208. Two positioning rods 2 308 slidably inserted into the lower die holder 101 and the lower die core 301 are symmetrically and fixedly connected to the side wall of the connecting plate 307. Anti-detachment blocks are fixedly connected to the ends of the positioning rod 1 212 and the positioning rod 2 308.

[0041] During specific implementation, the new upper die core 203 and the lower die core 301 are combined and placed between two lifting plates 405. Then, the new lower die core 301 is moved to the position of the lower die holder 101, and then the hydraulic cylinder two 404 contracts to drive the lower die core 301 to slide and embed into the lower die holder 101. Then, the hydraulic cylinder one 106 drives the upper die holder 201 to descend until it is embedded with the upper die core 203. After that, the hydraulic pump 412 pumps the hydraulic oil in the oil storage tank 413 back into the frame-shaped pipe 407, the first telescopic rod 409, and the second telescopic rod 414. Thus, the first telescopic rod 409 drives the driving member 410 to push the inclined surface chute frame 209 to move, so that it drives the L-shaped plate 207 to insert into the T-shaped groove 206, and the first positioning rod 212 inserts into the upper die core 203. At the same time, after the two second telescopic rods 414 extend, the compression spring 418 will squeeze the trapezoidal block 416 to move, and the trapezoidal block 416 drives the trapezoidal chute plate 305 to move, so that the clamping plate 306 inserts into the clamping groove 304. Then, the hydraulic cylinder one 106 drives the upper die holder 201 and the upper die core 203 to rise, so that the inclined surface chute frame 209 and the driving member 410 gradually slide and separate. Under the pulling of the tension spring 211, the L-shaped plate 207 is driven to remain clamped with the T-shaped groove 206 in the upper die core 203. Therefore, the upper die core 203 and the upper die holder 201 can be quickly positioned and installed.

[0042] As Figure 2 shown, in this embodiment, the support mechanism 100 includes a lower die holder 101. Slide rail plates 102 are fixedly connected to the opposite side walls of the lower die holder 101. The linear motor 403 is slidably connected to the slide rail plates 102. Diagonal support plates 103 fixedly connected to the lower die holder 101 are fixedly connected to the bottoms of the two slide rail plates 102. Four guide rods 204 are symmetrically and fixedly connected to the bottom of the upper die core 203. Four guide connection holes 302 slidably inserted with the guide rods 204 are formed in the top of the lower die core 301.

[0043] During specific implementation, then the linear motor 403 drives the frame 401 to move away from the position of the lower die holder 101. During this process, the trapezoidal block 416 and the trapezoidal chute plate 305 slide and separate, and the clamping plate 306 rises under the action of the return spring 310 and remains embedded and clamped with the clamping groove 304. Therefore, the lower die core 301 and the lower die holder 101 are completed with positioning and installation. In this way, the upper die core 203 and the lower die core 301 can be installed simultaneously, without relying on manual or mechanical means to lift the upper die core 203 to the position of the upper die holder 201 and then fix the installation components. Thus, it is possible to avoid personnel injury caused by the die core falling, and the rapid completion of the die core installation can enable the die casting machine to quickly be put into the production of the new landing gear strut.
