[0018] Please refer to Figures 1-10 The wax mold workpiece 5 is composed of a junction box wax mold 51 and a box cover wax mold 52. In this application, a double-station wax injection machine is used to manufacture the box cover wax mold 52. The present invention provides a technical solution: a piece-taking auxiliary mechanism for a double-station wax injection machine, which is used to take out the formed box cover wax mold 52, including a frame 1 and an operating table 11 fixed to one side of the frame 1. Two wax injection mechanisms 2 are installed on the top of the frame 1. A forming mold 3 is installed in each of the two wax injection mechanisms 2. The wax injection mechanism 2 and the forming mold 3 are used to cool the molten wax and form it into a box cover wax mold 52. The two wax injection machines The same picking component 4 is installed between the structures 2, and the picking component 4 includes an electric module 41. The electric module 41 is equipped with a lifting reversing mechanism 42, and two flipping mechanisms 43 are installed on the reversing mechanism 42. The two flipping mechanisms 43 are both equipped with adsorption mechanisms 44. The two adsorption mechanisms 44 are used to adsorb the box cover wax mold 52 in the forming mold 3. Then the reversing mechanism 42 brings the two adsorption mechanisms 44 close to each other. During this process, the two adsorption mechanisms 44 will carry the corresponding box cover wax mold 52 from bottom to top to perform a half-circle flip in opposite directions.

[0019] The reversing mechanism 42 includes a rectangular plate 421, and the flipping mechanism 43 includes a horizontal plate 1 431. The horizontal plate 1 431 is slidably mounted on the top of the rectangular plate 421, and a horizontal plate 2 432 is rotatably mounted on the top of the rectangular plate 421. A rectangular bar 4311 is fixedly mounted on one side of the two horizontal plates 431 close to each other. The two rectangular bars 4311 are symmetrically distributed along the center. A rack 1 423 is fixedly mounted on one side of the two rectangular bars 4311 close to each other. The two racks 1 423 are meshed with the same gear 1 424. A reduction motor 425 is fixedly mounted on the bottom of the rectangular plate 421. The output shaft of the reduction motor 425 rotates through the rectangular plate 421 and is fixedly connected to the gear 1 424.

[0020] The adsorption mechanism 44 includes a circular plate 441 fixed to the bottom of the second horizontal plate 432. A mold box 442 is fixedly installed at the bottom of the circular plate 441. A plurality of ventilation holes 444 are opened on the side of the mold box 442. A hard conduit 443 connected to the mold box 442 is fixedly installed through the circular plate 441.

[0021] Furthermore, when the circular plate 441 is in contact with the end surface 521 of the wax mold 52 of the box cover, the interior of the wax mold 52 of the box cover can be in a closed state.

[0022] A rectangular box 422 with an open bottom is fixedly installed on the top of the rectangular plate 421, and two horizontal plates 431 pass through the rectangular box 422 and are slidably connected to the rectangular box 422. Two accommodating grooves 426 are provided on the top of the rectangular box 422, and a pipe groove 427 for accommodating a hard conduit 443 is provided on the accommodating groove 426.

Limit blocks 428 are fixedly installed on the sides of the two rectangular strips 4311 away from each other, and the two limit blocks 428 are respectively slidably installed in the corresponding limit grooves 429.

[0023] Furthermore, the cooperation between the limiting block 428 and the limiting groove 429 can limit the translation distance of the horizontal plate 1 431; When the adsorption mechanism 44 is as Figure 8 In the state shown, the hard tube 443 on the adsorption mechanism 44 is stored in the tube groove 427, and the receiving groove 426 is used to accommodate the horizontal plate 2 432 in the folded state. By connecting the hard tube 443 to an external air source, the mold box 442 can be vacuumed.

[0024] A carrier plate 433 is provided at the end of the horizontal plate 1 431 away from the reversing mechanism 42, and a rotating shaft 434 is rotatably installed on the top of the horizontal plate 1 431. The rotating shaft 434 passes through the horizontal plate 2 432 and is fixedly connected to the horizontal plate 2 432. Gear 2 435 is fixedly installed at both ends of the rotating shaft 434. Two racks 2 439 are fixedly installed on the side of the rectangular box 422 close to the adsorption mechanism 44. The two racks 2 439 are respectively adapted to the corresponding gears 2 435. Support plates 4210 are fixedly installed on both sides of the rectangular plate 421.

[0025] Furthermore, the carrier plate 433 is used to support the second transverse plate 432, which not only allows it to flip only half a circle, but also ensures the parallel state between the first transverse plate 431 and the second transverse plate 432. The supporting plate 4210 is used to support the first transverse plate 431 to prevent it from bending and deformation.

[0026] Two second circular shafts 437 are rotatably mounted on the bottom of the horizontal plate 1 431 , and two sides of the horizontal plate 2 432 are rotatably mounted with first circular shafts 436 . The adjacent first circular shafts 436 and second circular shafts 437 are hooked with the same tension spring 438 .

[0027] Furthermore, the tension spring 438 can keep the horizontal plate 1 431 and the horizontal plate 2 432 brackets in a taut state, and the horizontal plate 2 432 will not shake when no external force is applied.

[0028] Two mounting brackets 45 are fixedly mounted on the slider of the electric module 41 , and electric push rods 46 are fixedly mounted on the two mounting brackets 45 . The bottom ends of the piston rods of the two electric push rods 46 are fixedly connected to the side surface of the rectangular plate 421 .

[0029] Furthermore, by controlling the extension and retraction of the two electric push rods 46 , the reversing mechanism 42 , the two flipping mechanisms 43 and the two adsorption mechanisms 44 can be driven to rise and fall synchronously.

[0030] The wax injection mechanism 2 includes a base plate 21 fixed to the top of the frame 1, and four guide rods 22 distributed in a rectangular shape are fixedly installed on the top of the base plate 21. The top of the four guide rods 22 is fixedly installed with the same top plate 23. The four guide rods 22 are slidably sleeved with the same movable plate 25. A cylinder 24 is fixedly installed above the top plate 23, and the piston rod end of the cylinder 24 is fixedly connected to the top of the movable plate 25. The forming mold 3 includes a lower mold base 31 fixed to the top of the base plate 21 and an upper mold base 32 fixed to the bottom of the movable plate 25. A groove 33 is provided on the top of the lower mold base 31, and a mold core 34 is fixed to the bottom of the groove 33.

[0031] Exhaust holes 35 and wax inlet holes 36 connected to the molding groove 33 are provided on both sides of the lower mold base 31. A joint 37 connected to the wax inlet hole 36 is fixedly installed on one side of the lower mold base 31. A three-axis slide 26 is fixedly installed on one side of the base plate 21, and a wax injection head 27 is fixedly installed on the three-axis slide 26.

[0032] Further, such as Figure 2 As shown, the three-axis slide 26 can drive the wax injection head 27 to move up and down and left and right; When the upper mold base 32 and the lower mold base 31 are fitted together, a cavity is formed between the mold core 34 and the mold groove 33. The wax injection head 27 then injects molten wax into the joint 37. The molten wax enters the cavity through the wax inlet hole 36. During this process, the air in the cavity is discharged through the exhaust hole 35. Water cooling channels are provided in the lower mold base 31 and the mold core 34. When the cooling water flows through the water cooling channels, it can accelerate the solidification of the molten wax in the mold cavity to form the box cover wax mold 52; After the box lid wax mold 52 is formed, the upper mold base 32 drives the mold core 34 to move up and separate from the box lid wax mold 52. At this time, the box lid wax mold 52 still remains in the mold groove 33, and then the adsorption mechanism 44 can take out the box lid wax mold 52 in the mold groove 33.

[0033] In this embodiment, when taking out the wax mold 52 of the box cover formed in the groove 33, the two adsorption mechanisms 44 are moved to the top of the two wax molds 52 of the box cover, and then the two adsorption mechanisms 44 are controlled to descend, so that the mold box 442 enters the interior of the wax mold 52 of the box cover, and the circular plate 441 is abutted against the end surface 521, and then the mold box 442 is evacuated through the two hard pipes 443, so that the wax mold 52 of the box cover is tightly adsorbed and connected with the adsorption mechanism 44. At this time, the shape of the take-out component 4 is as follows. Figure 4 、 Figure 5 As shown; Then the two adsorption mechanisms 44 are controlled to rise, so that the wax mold 52 of the box cover is separated from the groove 33, and then the reduction motor 425 is started to drive the gear 1 424 to rotate. The gear 1 424 pulls the two horizontal plates 1 431 closer to each other through the two racks 1 423. At this time, the two adsorption mechanisms 44 will synchronously approach each other. During the above process, as the gear 2 435 engages with the corresponding rack 2 439, the gear 2 435 will drive the rotating shaft 434 to rotate, and the rotating shaft 434 will then drive the horizontal plate 2 432 to rotate. The horizontal plate 2 432 will flip half a circle from bottom to top. At this time, the shape of the picking component 4 is as follows Figure 8 As shown; Afterwards, the electric module 41 drives the box cover wax mold 52 on the two adsorption mechanisms 44 to move to the top of the operating table 11, and subsequent staff can take the box cover wax mold 52 on the adsorption mechanism 44. During this process, the wax injection mechanism 2 and the forming mold 3 cooperate to form the next box cover wax mold 52.

[0034] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
