Description

Technical Field

[0001] The invention relates to the technical field of casting molds, in particular to an automobile mold for post-processing heavy metal solid waste. Background Art

[0002] Casting is the most basic method for producing aluminum alloy motor housings. Casting aluminum alloy is an aluminum alloy that fills a casting mold with molten metal to obtain various shapes of parts. It has the advantages of low density, high specific strength, good corrosion resistance and casting processability, and is less restricted by part structure design.

[0003] The gearbox is an important component in automobiles or other mechanical equipment, used to control power transmission and adjust the speed of the vehicle. Gearbox casting technology refers to the technical process of making the gearbox shell or housing through a casting process of metal materials, usually cast iron materials. The molten metal is poured into the mold to fill the cavity of the mold to form the gearbox shell.

[0004] After the gearbox housing is cast, some of its thin edges need to be drilled. The existing processing procedure usually places the formed casting into a drilling device for positioning before drilling. Therefore, the casting needs to be cut, then transported to the drilling device for positioning, and then drilled. The whole process takes a lot of time and requires coordination with the drilling equipment, which is also relatively costly. Summary of the Invention

[0005] The purpose of the present invention is to provide an automobile mold for post-processing heavy metal solid waste in response to the deficiencies of the prior art.

[0006] To achieve the above object, the technical solution of the present invention is as follows:

[0007] An automobile mold for post-processing heavy metal solid waste includes a casting mold and a support mechanism for mounting the casting mold.

The guide structure includes a fixed top plate and a fixed bottom plate arranged at intervals, with a guide rod and a vertical guide plate mounted between the fixed top plate and the fixed bottom plate, the vertical guide plate being mounted to an outer side wall. The lower mold assembly is mounted on the top of the fixed bottom plate, the upper mold assembly is formed with a mold guide hole coaxially mated with the guide rod, the mold guide hole being mounted with a guide sleeve slidably mated with the guide rod, and the upper mold assembly slides along the guide rod between the fixed top plate and the fixed bottom plate.

[0008] The lower mold assembly includes a fixed mold assembly plate and a fixed mold core installed on the top of the fixed mold assembly plate;

[0009] The upper mold assembly includes a movable mold plate and a movable mold core installed at the bottom of the movable mold plate; an adsorption cavity is formed in the movable mold core, and a plurality of electromagnets are installed in the adsorption cavity, which can adsorb and position the formed casting on the movable mold core;

[0010] The support mechanism includes a support frame provided with a rotatable support shaft, a vertical guide plate provided with a support sleeve coaxially aligned with the support shaft and used to mount the support shaft; the vertical guide plate can be longitudinally swung around the axis of the support shaft through the support sleeve;

[0011] The support frame is further provided with a multifunctional manipulator, which includes an execution seat capable of moving in multiple directions, and the execution seat is equipped with a first drive mechanism and a second drive mechanism, wherein the first drive mechanism includes a forming mechanism for drilling and forming a thin surface of the casting;

[0012] The forming mechanism includes a drilling seat, on which a drilling head is installed; the drilling head includes a knife cylinder, on which a first guide hole is axially formed, a first drilling tool is slidably installed, a lifting block that can be lifted and lowered is installed in the first guide hole, and the top of the lifting block is connected to the bottom of the first drilling tool; a chamfered inclined surface is formed on the top of the lifting block, and the chamfered inclined surface is parallel to the bottom surface of the sliding cylinder; a connecting column is installed on the top of the lifting block, and a bottom insertion hole for inserting the connecting column is formed at the bottom of the first drilling tool; the connecting column is formed with a hollow hole of a hollow structure, and an elastically retracted locking block and a locking groove for radial sliding of the locking block are radially formed on the top of the connecting column, and a locking groove for embedding the locking block is formed on the inner side wall of the bottom insertion hole;

[0013] The second driving mechanism includes a blanking fixture, which can clamp and discharge the demoulded casting and the waste material in the cavity; the support frame is also provided with a post-processing mechanism, which includes a crushing box.

[0014] The beneficial effects of the present invention are as follows: the present invention adopts a supporting mechanism to swing the casting mold installed on the supporting frame in the vertical direction. After the casting is completed, the product can be adsorbed by the electromagnet of the movable model core to prevent the product from falling. After the casting mold is swung, it changes from a vertical posture to an inclined posture, which can form a better angle for the forming mechanism of the multi-functional manipulator to drill holes. When drilling, the electromagnet of the movable model core can position the product without offset or displacement, and the drilling operation can be completed without disassembly from the mold, eliminating the subsequent additional drilling procedures, greatly reducing the processing steps, improving production efficiency, reducing the separate arrangement of drilling equipment, and greatly reducing costs. After the drilling is completed, the unloading fixture of the multi-functional manipulator can clamp the product and unload it to the work station under the drive of the finger cylinder, and then the unloading fixture continues to clamp the waste material and put it into the crushing box for crushing and post-processing.

[0059] The present invention is described in detail below with reference to the accompanying drawings.

[0060] like Figure 1-13 As shown, an automobile mold for post-processing heavy metal solid waste includes a casting mold 1 and a support mechanism 13 for mounting the casting mold 1. The casting mold 1 includes an upper mold module 11 and a lower mold module 110. A guide structure 12 is provided between the upper mold module 11 and the lower mold module 110. The guide structure 12 includes a fixed top plate 121 and a fixed bottom plate 122 arranged at intervals. A guide rod 123 and a vertical guide plate 124 are installed between the fixed top plate 121 and the fixed bottom plate 122. The vertical guide plate 124 is installed on the outer wall The lower mold module 110 is installed on the top of the fixed base plate 122, and the upper mold module 11 is formed with a mold guide hole 125 that is coaxial with the guide rod 123. The mold guide hole 125 is installed with a guide sleeve 126 that slides with the guide rod 123. The upper mold module 11 slides along the guide rod 123 between the fixed top plate 121 and the fixed base plate 122; through the sliding of the guide sleeve 126 and the guide rod 123, the upper mold module 11 and the lower mold module 110 can move closer to or away from each other, thereby realizing mold closing and mold opening.

[0061] The lower mold assembly 110 includes a fixed mold plate 115 and a fixed mold core 116 mounted on top of the fixed mold plate 115. The upper mold assembly 11 includes a movable mold plate 111 and a movable mold core 112 mounted on the bottom of the movable mold plate 111. A vertically arranged mold opening and closing lift cylinder 127 is mounted on the fixed top plate 121. The drive end of the mold opening and closing lift cylinder 127 passes through the fixed top plate 121 and connects to the movable mold plate 111. Under the lifting and lowering drive of the mold opening and closing lift cylinder 127, the upper mold assembly 11 can move away from or closer to the lower mold assembly 110 to achieve mold opening and closing.

[0062] The support mechanism 13 includes a support frame 131, which is provided with a rotatable support shaft 132, and the vertical guide plate 124 is installed with a support sleeve 133 coaxially aligned with the support shaft 132 and used to install the support shaft 132; after the mold is opened, the vertical guide plate 124 can swing longitudinally around the axis of the support shaft 132 through the support sleeve 133, so that the casting mold 1 installed on the vertical support plate can swing longitudinally, so that the product between the upper mold module 11 and the lower mold module 110 is tilted upward.

[0063] Preferably, a first transverse frame 134 and a second transverse frame 135 are provided on either side of the support frame 131. The first transverse frame 134 and the second transverse frame 135 are respectively located on either side of the support frame 131. The first transverse frame 134 is equipped with a swing mechanism that drives the casting mold 1 to swing longitudinally. The swing mechanism includes a swing and telescopic cylinder 136 mounted on the first transverse frame 134. The driving end of the swing and telescopic cylinder is hinged to the vertical guide plate 124. A guide bearing seat 137 is installed on the top of the support frame 131. The two ends of the support shaft 132 are respectively mounted on the guide bearing seats 137. The support shaft 132 can rotate within the guide bearing seats 137. In this embodiment, after the product is cast, the upper mold module 11 and the lower mold module 110 are separated from each other. At this time, the product is still adhered to the dynamic mold core 112 of the upper mold module 11. Then the swing telescopic cylinder 136 of the first transverse frame 134 works, and its telescopic rod retracts, so that the vertical guide plate 124 changes from a vertical posture to an inclined posture, so that the product between the upper mold module 11 and the lower mold module 110 is tilted upward.

[0064] An adsorption cavity 113 is formed in the dynamic model core 112, and a plurality of electromagnets 114 are installed in the adsorption cavity 113. The electromagnets 114 can adsorb and position the formed casting on the dynamic model core 112; after the product is cast, the electromagnets 114 in the adsorption cavity 113 are energized. At this time, the dynamic model core 112 of the upper mold module 11 has magnetism, and the cast product can be magnetically attracted by the passive model core 112, so that the product fits the dynamic model core 112. After the mold is opened, the product will not fall from the mold, thus maintaining the adsorbed state. It should be noted that the contact surface between the electromagnet 114 and the product is adapted to the shape of the dynamic model core 112, ensuring that the molded product has the required precision. In addition, the dynamic mold assembly plate 111 and the dynamic model core 112 are both provided with a circuit cavity for arranging power lines to ensure normal power supply, so that when the electromagnet 114 is energized, it can adsorb the iron casting and ensure the stable positioning of the casting.

[0065] After forming, the casting mold 1 of the vertical support plate is tilted upward, allowing drilling of thin edges of the formed product. The second transverse frame 135 is equipped with a multifunctional manipulator 2, which includes an actuator base 211 capable of moving in multiple directions. The actuator base 211 is equipped with a first drive mechanism and a second drive mechanism. The actuator base 211 includes a first rotating disk 214 and a rotating ring 212 coaxially mounted on the periphery of the first rotating disk 214. The first drive mechanism is mounted on the first rotating disk 214 and includes a forming mechanism 3 for drilling holes in the thin edges of the casting.

[0066] The forming mechanism 3 includes a drilling seat 215 , on which a drilling head 31 is installed; the drilling seat 215 is provided with a lifting cylinder to drive the drilling head 31 to move up and down.

[0067] The drilling head 31 includes a knife cylinder 310, which is axially formed with a first guide hole 315, and a first drilling knife 317 is slidably installed in the first guide hole 315. The knife cylinder 310 is also obliquely formed with a pair of second guide holes 316, the second guide holes 316 are located outside the first guide hole 315, and the bottom of the second guide hole 316 is connected to the first guide hole 315. A sliding cylinder 32 is slidably installed in the second guide hole 316, and a lifting block 313 that can be lifted and lowered is installed in the first guide hole 315. The top of the lifting block 313 is connected to the bottom of the first drilling knife 317, and a second drilling knife 318 that can swing longitudinally is installed on the top of the sliding cylinder 32; the knife cylinder 310 is also provided with a positioning component for keeping the extended second drilling knife 318 in a vertical posture, and the positioning component includes a transverse positioning rod 326 arranged transversely, and the second drilling knife 318 is penetrated by the second drilling knife 318. A positioning hole 327, the knife cylinder 310 is horizontally formed with a second positioning hole 328 that is coaxially aligned with the transverse positioning rod 326; the lifting block 313 rises along the first guide hole 315, so that the first drilling tool 317 protrudes outward along the first guide hole 315; at the same time, the sliding cylinder 32 located in the second guide hole 316 can be lifted along the second guide hole 316 under the action of the lifting block 313, and the second drilling tool 318 installed on the top of the sliding cylinder 32 changes from an inclined posture to a vertical posture. After rising to the required position, the transverse positioning rod 326 is coaxially aligned with the first positioning hole 327 and the second positioning hole 328, and the transverse positioning rod 326 passes through the first positioning hole 327 and the second positioning hole 328 in sequence to position the second drilling tool 318, thereby preventing the second drilling tool 318 from swinging during drilling and maintaining a vertical posture for drilling. Multiple second drilling tools 318 cooperate with the first drilling tool 317 to simultaneously drill holes in multiple locations on the thin surface of the casting. Only a single lifting block 313 is required to drive the multiple drilling tools to achieve drilling. This reduces the number of pneumatic equipment and pneumatic structures. Furthermore, because the drilling base 215 can move the drilling head 31 upward and downward, the multiple drilling tools of the drilling head 31 can be raised to different heights according to the required drilling depth. The height to which the drilling tools extend also varies, and the drilling depth also varies.

[0068] Furthermore, an inwardly concave movable groove 321 is formed on the top of the sliding cylinder 32, and a hinge block 324 is installed on the inwardly concave movable groove 321. The inner end of the second drilling tool 318 is rotatably connected to the hinge block 324, and the inwardly concave movable groove 321 can allow the second drilling tool 318 to swing to a vertical posture; a vertical groove 325 is concavely formed on the top of the knife cylinder 310, and the bottom of the vertical groove 325 is connected to the second guide hole 316. The concave movable groove 321 includes a first groove wall 322 arranged vertically and a second groove wall 323 forming an acute angle with the first groove wall 322, and the second groove wall 323 is parallel to the sliding cylinder 32; when the lifting block 313 is raised along the first guide hole 315, the sliding cylinder 32 can be raised along the second guide hole 316. At this time, the second drilling tool 318 hinged at the outer end of the sliding cylinder 32 is continuously changed from an inclined posture to a vertical posture under the action of the vertical groove 325. The inner end of the second drilling tool 318 swings between the first groove wall 322 and the second groove wall 323 through the hinge block 324. After becoming a vertical posture, the inner side edge of the second drilling tool 318 is in contact with the first groove wall 322, thereby maintaining a vertical posture. After the lifting block 313 retracts, the first drilling tool 317 retracts along the first guide hole 315, and the sliding cylinder 32 retracts along the second guide hole 316 under the action of gravity. At this time, the first drilling tool 317 and the second drilling tool 318 both retract and will not be exposed outward, effectively protecting the first drilling tool 317 and the second drilling tool 318.

[0069] The bottom of the knife cylinder 310 is connected to the drilling seat 215. The drilling seat 215 is formed with a bottom guide hole 311 coaxially aligned with the first guide hole 315. A lifting piston rod 312 capable of lifting and lowering movement is installed in the bottom guide hole 311. The top of the lifting piston rod 312 is connected to the lifting block 313. The lifting piston rod 312 is axially lifted and lowered under the action of the lifting cylinder of the bottom guide hole 311, thereby driving the lifting block 313 to lift and lower, which can drive the first drilling tool 317 and the second drilling tool 318 to rise or hide.

[0070] Preferably, a chamfered slope 314 is formed on the top of the lifting block 313, and the chamfered slope 314 is parallel to the bottom surface of the sliding cylinder 32. When the lifting block 313 is lifted along the first guide hole 315, the chamfered slope 314 on the top of the lifting block 313 slides with the slope of the bottom surface of the sliding cylinder 32, driving the sliding cylinder 32 to rise along the second guide hole 316; the outer diameter of the second drilling tool 318 is smaller than the outer diameter of the first drilling tool 317, and the outer wall of the second drilling tool 318 is formed with a guide expansion hole coaxially aligned with the first positioning hole 327 for the transverse positioning rod 326 to guide through; the outer wall of the knife cylinder 310 is provided with a transverse The horizontal telescopic cylinder 329 is arranged in the right direction, and the driving end of the horizontal telescopic cylinder 329 is connected to the horizontal positioning rod 326. The second drilling tool 318 at the sliding outer end is continuously changed from an inclined posture to a vertical posture under the action of the vertical groove 325. After the second drilling tool 318 is raised into place, the horizontal positioning rod 326 is coaxially aligned with the first positioning hole 327 and the second positioning hole 328. The horizontal positioning rod 326 passes through the first positioning hole 327 and the second positioning hole 328 in turn to position the second drilling tool 318, thereby preventing the second drilling tool 318 from swinging during drilling and maintaining a vertical posture for drilling.

[0071] Preferably, the bottom of the first drilling tool 317 is formed with a bottom insertion hole 337 for the connecting column 331 to be inserted; the connecting column 331 is formed with a hollow hole 332 of a hollow structure, the top of the connecting column 331 is radially formed with an elastically retracted locking block 339 and a locking groove 3390 for the radial sliding of the locking block 339, the inner side wall of the bottom insertion hole 337 is formed with a locking groove 338 for the locking block 339 to be embedded, the lifting block 313 is internally formed with a tool changing chamber 33, the top of the tool changing chamber 33 is connected to the hollow hole 332, the tool changing chamber 33 is provided with a locking platform that can move up and down, and the top of the locking platform is installed with The locking rod 333 is movable in the hollow hole 332, and a locking inclined surface 334 is formed on the top of the locking rod 333, which slides with the locking block 339; when the locking rod 333 is raised, the locking rod 333 drives the locking block 339 to cooperate with the locking groove 338 of the bottom insertion hole 337 along the locking groove 3390 through the locking inclined surface 334 to lock and install the first drilling tool 317; after the locking rod 333 retracts, the locking block 339 moves away from the locking groove 338 of the bottom insertion hole 337 along the locking groove 3390 under the elastic action of the compression spring, so that the tool changing mechanism can replace the first drilling tool 317.

[0072] The lifting cylinder provided in the tool changing chamber 33 can drive the locking rod 333 to perform lifting movement along the hollow hole 332 of the locking platform. Before drilling, the lifting cylinder can drive the locking rod 333 to rise along the hollow hole 332 of the locking platform. The locking rod 333 slides with the locking block 339 of the locking groove 3390 through the locking inclined surface 334, driving the locking block 339 to move radially outward and embed into the locking groove 338 of the first drilling tool 317, which can lock the first drilling tool 317 for drilling. When the first drilling tool 317 needs to be changed, the lifting cylinder drives the locking rod 333 to descend and retreat. After the locking rod 333 retreats, the locking block 339 moves along the locking groove 3390 away from the locking groove 338 of the bottom insertion hole 337 under the action of elasticity. At this time, the first drilling block is in an active state, and the tool changing mechanism can replace the first drilling tool 317.

[0073] It should be noted that the first drilling tool 317 is composed of a mounting portion 335 and a drilling portion 336 formed on the top of the mounting portion 335. When the first drilling tool 317 needs to be replaced, since the outer diameter of the mounting portion 335 of each first drilling tool 317 is the same and the outer diameter of the drilling portion 336 is different, each first drilling tool 317 can be installed in the first guide hole 315 of the knife barrel 310 after replacement.

[0074] It should be noted that the first drilling tool 317 is kept facing upward by the lifting block 313. The second drilling tool 318 is kept vertical by the positioning assembly. When drilling, the first drilling tool 317 and the second drilling tool 318 will not deviate or retreat, thereby ensuring stability during drilling.

[0075] In addition, the movable mold plate 111 and the movable mold core 112 have a guide hole structure 43, and the guide structure 12 includes a first guide drill hole 431 and a second guide drill hole 432 coaxially formed on the movable mold plate 111 and the movable mold core 112 respectively. The first guide drill hole 431 is slidably installed with a first blocking rod 433, and the second guide drill hole 432 is slidably installed with a second blocking rod 434. The inner end surfaces of the first blocking rod 433 and the second blocking rod 434 are adapted to the shape of the molding surface of the movable mold core 112; the fixed top plate 121 is provided with a first opening lifting cylinder 435 for driving the first blocking rod 433 to rise and fall, and a second opening lifting cylinder 436 for driving the second blocking rod 434 to rise and fall. When drilling, after the first drilling tool 317 passes through the hole to be drilled, it cooperates with the first guide drilling hole 431 of the dynamic model core 112, and the first blocking rod 433 located in the first guide drilling hole 431 retracts under the drive of the first hole opening lifting cylinder 435 to allow the first drilling tool 317 to enter; similarly, after the second drilling tool 318 passes through the hole to be drilled, it cooperates with the second guide drilling hole 432 of the dynamic model core 112, and the first blocking rod 433 located in the second guide drilling hole 432 retracts under the drive of the second hole opening lifting cylinder 436 to allow the second drilling tool 318 to enter; prevent the drilling tool from damaging the dynamic model core 112.

[0076] It should be noted that the hole positions of the first guide drill hole 431 and the second guide drill hole 432 and the corresponding first blocking rod 433 and the second blocking rod 434 are all larger than the radius of the conventional hole positions. Therefore, after the first drilling tool 317 and the second drilling tool 318 are replaced with different sizes, it is ensured that the first drilling tool 317 and the second drilling tool 318 can be guided into the corresponding first guide drill hole 431 and the second guide drill hole 432.

[0077] After the product is processed and formed by the casting mold 1, when drilling is required, the upper mold module 11 and the lower mold module 110 need to be separated. In this regard, the fixed base plate 122 is provided with a demoulding mechanism 4 that drives the casting to separate from the fixed mold core 116. The demoulding mechanism 4 includes a bottom bracket 41 installed at the bottom of the fixed base plate 122. The bottom bracket 41 is installed with a demoulding lifting cylinder 411. The driving end of the demoulding lifting cylinder 411 is installed with a demoulding driving plate 412. The demoulding driving plate 412 is installed with multiple demoulding rods 413 that can move through the fixed base plate 122. The demoulding driving plate 412 is provided with a bottom through hole 415 for the demoulding rod 413 to pass through; the fixed mold plate 115 and the fixed mold core 116 are respectively formed with a demoulding hole 414 for the demoulding rod 413 to move through. When the upper mold assembly 11 and the lower mold assembly 110 are separated by about 1 cm, the demolding mechanism 4 operates. The demolding rod 413 installed at the bottom of the fixed base plate 122, driven by the demolding lifting cylinder 411, passes through the corresponding demolding hole 414, allowing the casting located on the fixed mold core 116 to be separated. During the subsequent demolding process, the product is prevented from being stuck to the fixed mold core 116. This ensures that the product can be attracted by the movable mold core 112 equipped with the electromagnet 114. After being attracted by the movable mold core 112, it has a positioning function during drilling.

[0078] Preferably, a sensing column 42 is installed at the bottom of the demoulding drive plate 412, and the sensing column 42 is provided with a first sensing sleeve 421 and a second sensing sleeve 422 arranged at intervals. The axial position of the first sensing sleeve 421 and the second sensing sleeve 422 can be adjusted; a sensing plate 423 is installed at the bottom of the fixed base plate 122, and the sensing plate 423 is installed with a contact sensor 424. The sensing end of the contact sensor 424 is installed with a touch plate 425, and the touch plate 425 is formed with a mounting long groove 426 along the length direction, and the mounting long groove 426 is installed with a contact sensor 4 The touch panel 425 is provided with a sliding connection block 427 connected to the sensing end of the contact sensor 424. A sensing roller 428 is mounted on the outer end of the touch panel 425, which contacts and cooperates with the first sensing sleeve 421 and the second sensing sleeve 422. In this embodiment, when the demolding rod 413 moves, the first sensing sleeve 421 and the second sensing sleeve 422 mounted on the bottom of the demolding drive plate 412 come into contact and cooperate with the sensing roller 428 of the contact sensor 424, i.e., they roll together. The touch panel 425, equipped with the sensing roller 428, swings around the sensing end of the contact sensor 424, thereby outputting a signal. Furthermore, the sliding connection block 427 can be adjusted along the length of the mounting slot 426 of the touch panel 425, thereby adjusting the distance between the sensing roller 428 and the sensing sleeve, thereby adjusting the swing angle of the touch panel 425.

[0079] Furthermore, the contact sensor 424 is an angular displacement sensor with angular swing. The contact sensor 424 is connected to the demolding lifting cylinder 411 signal. The first sensing sleeve 421 is located below the second sensing sleeve 422. The distance between the first sensing sleeve 421 and the second sensing sleeve 422 does not exceed 1 cm. When the demolding lifting cylinder 411 is not working, the first sensing sleeve 421 is located on the top of the sensing roller 428. When it needs to be extended to work, the sensing roller 428 contacts and cooperates with the first sensing sleeve 421 and the second sensing sleeve 422 in turn. After contacting the second sensing sleeve 422, the contact sensor 424 outputs a pause signal to the demolding lifting cylinder 411 to prevent the piston rod of the demolding lifting cylinder 411 from extending too long.

[0080] The second drive mechanism is mounted on a rotating ring 212, which is movably mounted on a first rotating disk 214 with damping. The second drive mechanism on the rotating ring 212 can be adjusted as needed, specifically adjusting its angle. The second drive mechanism includes a blanking fixture 21, which can hold and unload the demolded casting or scrap material from the cavity. Driven by a finger cylinder 213, the blanking fixture 21 can hold and unload the product to the workstation. The support frame 131 is also provided with a post-processing mechanism 22, which includes a crushing box 221. A feeding opening 229 is provided on the top of the crushing box 221. The crushing box 221 is equipped with a first pressure roller 222 and a second pressure roller 223 arranged at intervals. The crushing box 221 is provided with a guide movable groove 224 for the lateral movement of the first pressure roller 222 and the second pressure roller 223. A first motor seat 225 and a second motor seat 226 are provided on the side of the crushing box 221. The first motor seat 225 is equipped with a first universal joint 227, and the second motor seat 226 is equipped with a second universal joint 228. The first universal joint 227 is connected to the first pressure roller 222, and the second universal joint 228 is connected to the second pressure roller 223. By driving the first cardan shaft 227 and the second cardan shaft 228, when adjusting the positions of the first pressure roller 222 and the second pressure roller 223 in the crushing box 221, the first pressure roller 222 and the second pressure roller 223 slide along the guide movable groove 224 of the crushing box 221, and the first cardan shaft 227 and the second cardan shaft 228 bend accordingly. When the first motor base 225 and the second motor base 226 output power, the power can still be output to the corresponding first pressure roller 222 and the second pressure roller 223 through the first cardan shaft 227 and the second cardan shaft 228, without moving the first motor base 225 and the second motor base 226, thereby greatly improving the adjustment efficiency.

[0081] After the drilling is completed, the second driving mechanism works, and the unloading fixture 21 driven by the finger cylinder 213 can clamp the product and unload it to the work station. Then, the unloading fixture 21 continues to clamp the waste material and place it into the crushing box 221 for crushing and post-processing.

[0082] The present invention adopts a support mechanism 13 to swing the casting mold 1 installed on the support frame 131 in the vertical direction. After casting is completed, the product can be adsorbed by the electromagnet 114 of the movable model core 112 to prevent the product from falling. After the casting mold 1 swings, it changes from a vertical posture to an inclined posture, which can form a better angle for the forming mechanism 3 of the multifunctional manipulator 2 to drill holes. When drilling, the electromagnet 114 of the movable model core 112 can position the product without offset or displacement, and the drilling operation can be completed without disassembly from the mold, eliminating the subsequent additional drilling procedures, greatly reducing the processing steps, improving production efficiency, reducing the separate arrangement of drilling equipment, and greatly reducing costs; after drilling is completed, the unloading fixture 21 of the multifunctional manipulator 2 can clamp the product and unload it to the work station under the drive of the finger cylinder 213, and then the unloading fixture 21 continues to clamp the metal waste and place it into the crushing box 221 for crushing and post-processing, and then it can be melted and reused as casting liquid.

[0083] In summary, it can be seen that the present invention has the above-mentioned excellent characteristics, which can enhance its performance unprecedented in the past and become a product with great practical value.
