Description

Technical Field

[0001] This invention relates to the field of wax injection machine part removal technology, and in particular to a part removal auxiliary mechanism for a dual-station wax injection machine. Background Technology

[0002] A wax injection machine is a device used for mold injection molding. Thermocouple junction boxes are an important component of thermocouple temperature measurement systems (including the junction box and its cover), primarily used to protect the electrical connection points of the thermocouple. They are typically formed using the lost-wax casting method. A wax injection machine can be used to manufacture wax molds for thermocouple junction boxes (as per the instruction manual). Figure 9-10 The wax model of the junction box and the wax model of the box cover are shown.

[0003] Existing dual-station wax injection machines typically require two operators. Due to varying levels of cooperation among the operators, the time required to remove the wax mold differs, which can easily affect production efficiency. Furthermore, the labor costs for two operators are relatively high. Therefore, a part removal auxiliary mechanism for dual-station wax injection machines is proposed. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the present invention proposes a part-removal auxiliary mechanism for a dual-station wax injection machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a part-retrieving auxiliary mechanism for a dual-station wax injection machine, comprising a frame and an operating table fixed to one side of the frame. Two wax injection mechanisms are installed on the top of the frame, and each of the two wax injection mechanisms is equipped with a molding die. The wax injection mechanism and the molding die cooperate to cool and solidify the molten wax into a box lid wax model. A common part-retrieving component is installed between the two wax injection mechanisms. The part-retrieving component includes an electric module, on which a lifting reversing mechanism is installed. Two flipping mechanisms are installed on the reversing mechanism, and each of the two flipping mechanisms is equipped with an adsorption mechanism. The two adsorption mechanisms are used to adsorb the box lid wax model in the molding die. Then, the reversing mechanism brings the two adsorption mechanisms closer to each other. During this process, the two adsorption mechanisms carry the corresponding box lid wax model and flip it in opposite directions from bottom to top.

[0006] Preferably, the reversing mechanism includes a rectangular plate, and the flipping mechanism includes a horizontal plate one. The horizontal plate one is slidably mounted on the top of the rectangular plate, and a horizontal plate two is rotatably mounted on the top of the rectangular plate. Rectangular bars are fixedly mounted on the sides of the two horizontal plates one that are close to each other. The two rectangular bars are centrally symmetrically distributed. A rack one is fixedly mounted on the sides of the two rectangular bars that are close to each other. The two racks one are meshed with the same gear one. A reduction motor is fixedly mounted on the bottom of the rectangular plate. The output shaft of the reduction motor rotatably passes through the rectangular plate and is fixedly connected to the gear one.

[0007] Preferably, the adsorption mechanism includes a circular plate fixed to the bottom of the horizontal plate, a mold box fixedly installed at the bottom of the circular plate, a plurality of ventilation holes being opened on the side of the mold box, and a rigid conduit connected to the mold box being fixedly installed through the circular plate.

[0008] Preferably, a rectangular box with an open bottom is fixedly installed on the top of the rectangular plate, and two horizontal plates pass through the rectangular box and are slidably connected to it. Two receiving grooves are opened on the top of the rectangular box, and the receiving grooves are provided with tube grooves for accommodating rigid conduits. Two limiting grooves are provided on the inner walls of both sides of the rectangular box in a centrally symmetrical manner. Limiting blocks are fixedly installed on the side of the two rectangular bars that are far apart from each other, and the two limiting blocks are slidably installed in the corresponding limiting grooves.

[0009] Preferably, the end of the horizontal plate away from the reversing mechanism is provided with a carrier plate, the top of the horizontal plate is rotatably mounted with a rotating shaft, the rotating shaft passes through the horizontal plate and is fixedly connected to the horizontal plate, and gears are fixedly mounted at both ends of the rotating shaft. Two racks are fixedly mounted on the side of the rectangular box near the adsorption mechanism, and the two racks are respectively adapted to the corresponding gears. Support plates are fixedly mounted on both sides of the rectangular plate.

[0010] Preferably, two round shafts are rotatably mounted on the bottom of the horizontal plate one, and round shafts one are rotatably mounted on both sides of the horizontal plate two. The same tension spring is hooked on the adjacent round shafts one and two.

[0011] Preferably, two mounting brackets are fixedly installed on the slider of the electric module, and electric push rods are fixedly installed on both mounting brackets. The bottom ends of the piston rods of the two electric push rods are fixedly connected to the side of the rectangular plate.

[0012] Preferably, the wax injection mechanism includes a base plate fixed to the top of the frame, four guide rods arranged in a rectangular pattern are fixedly installed on the top of the base plate, the top ends of the four guide rods are fixedly installed on the same top plate, the same movable plate is slidably sleeved on the four guide rods, a cylinder is fixedly installed through the top of the top plate, the piston rod end of the cylinder is fixedly connected to the top of the movable plate, and the molding die includes a lower mold base fixed to the top of the base plate and an upper mold base fixed to the bottom of the movable plate. The top of the lower mold base has a groove, and the bottom of the groove has a mold core fixed.

[0013] Preferably, the lower mold base has vent holes and wax inlets connected to the mold groove on both sides, a connector connected to the wax inlet is fixedly installed on one side of the lower mold base, a three-axis slide is fixedly installed on one side of the base plate, and a wax injection head is fixedly installed on the three-axis slide.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. The present invention can simultaneously remove the box lid wax molds from two molding molds through the part-removing component. Then, by shortening the distance between the two box lid wax molds, a single worker can remove the two box lid wax molds at the same time, which effectively improves the part-removing efficiency. Moreover, there is no need to put hands into the wax injection mechanism during the process of removing the box lid wax molds, which greatly improves the safety of part removal.

[0016] 2. By combining the flipping mechanism and the adsorption mechanism, the wax model of the box lid is flipped after being taken out of the mold groove. This not only makes it easier for the staff to take the wax model of the box lid on the adsorption mechanism, but also ensures that the wax model of the box lid will not fall off the adsorption mechanism even if the staff fails to take the wax model of the box lid on the adsorption mechanism immediately.

[0031] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please refer to Figures 1-10The wax model workpiece 5 consists of a junction box wax model 51 and a box cover wax model 52. In this application, a dual-station wax injection machine is used to manufacture the box cover wax model 52. This invention provides a technical solution: a part-removing auxiliary mechanism for a dual-station wax injection machine, used to remove the formed box cover wax model 52, including a frame 1 and an operating table 11 fixed on one side of the frame 1. Two wax injection mechanisms 2 are installed on the top of the frame 1. Each of the two wax injection mechanisms 2 is equipped with a forming mold 3. The wax injection mechanism 2 and the forming mold 3 cooperate to cool and solidify the molten wax into the box cover wax model 52. The same part-retrieving component 4 is installed between the components 2. The part-retrieving component 4 includes an electric module 41. A lifting reversing mechanism 42 is installed on the electric module 41. Two flipping mechanisms 43 are installed on the reversing mechanism 42. Each of the two flipping mechanisms 43 is equipped with an adsorption mechanism 44. The two adsorption mechanisms 44 are used to adsorb the box lid wax mold 52 in the molding mold 3. Then, the reversing mechanism 42 brings the two adsorption mechanisms 44 closer to each other. During this process, the two adsorption mechanisms 44 will carry the corresponding box lid wax mold 52 and flip it in opposite directions from bottom to top.

[0033] The reversing mechanism 42 includes a rectangular plate 421, and the flipping mechanism 43 includes a horizontal plate 431. The horizontal plate 431 is slidably mounted on the top of the rectangular plate 421. A second horizontal plate 432 is rotatably mounted on the top of the rectangular plate 421. Rectangular bars 4311 are fixedly mounted on the side of the two horizontal plates 431 that are close to each other. The two rectangular bars 4311 are centrally symmetrically distributed. A rack 423 is fixedly mounted on the side of the two rectangular bars 4311 that are close to each other. The same gear 424 meshes between the two racks 423. 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 424.

[0034] The adsorption mechanism 44 includes a circular plate 441 fixed to the bottom of the horizontal plate 432. A mold box 442 is fixedly installed on the bottom of the circular plate 441. Multiple ventilation holes 444 are opened on the side of the mold box 442. A rigid conduit 443 connected to the mold box 442 is fixedly installed through the circular plate 441.

[0035] Furthermore, when the circular plate 441 is attached to the end face 521 on the box lid wax mold 52, the inside of the box lid wax mold 52 can be sealed.

[0036] A rectangular box 422 with an open bottom is fixedly installed on the top of the rectangular plate 421. Two horizontal plates 431 pass through the rectangular box 422 and are slidably connected to it. Two receiving grooves 426 are opened on the top of the rectangular box 422. The receiving grooves 426 are provided with tube grooves 427 for receiving rigid conduits 443. Two limiting grooves 429 are provided on the inner walls of both sides of the rectangular box 422 in a centrally symmetrical manner. Limiting blocks 428 are fixedly installed on the side of the two rectangular bars 4311 that are far apart from each other. The two limiting blocks 428 are slidably installed in the corresponding limiting grooves 429.

[0037] Furthermore, the translational distance of the horizontal plate 431 can be limited by the cooperation of the limiting block 428 and the limiting groove 429.

[0038] When the adsorption mechanism 44 is as follows Figure 8 In the state shown, the hard conduit 443 on the adsorption mechanism 44 is housed in the tube groove 427, and the receiving groove 426 is used to accommodate the horizontal plate 432 in the folded state. By connecting the hard conduit 443 to an external air source, a vacuum can be drawn inside the mold box 442.

[0039] A carrier plate 433 is provided at the end of the horizontal plate 431 away from the reversing mechanism 42. A rotating shaft 434 is rotatably installed on the top of the horizontal plate 431. The rotating shaft 434 passes through the horizontal plate 432 and is fixedly connected to the horizontal plate 432. Gears 435 are fixedly installed at both ends of the rotating shaft 434. Two racks 439 are fixedly installed on the side of the rectangular box 422 near the adsorption mechanism 44. The two racks 439 are respectively adapted to the corresponding gears 435. Support plates 4210 are fixedly installed on both sides of the rectangular plate 421.

[0040] Furthermore, the carrier plate 433 is used to support the second horizontal plate 432, which not only allows it to rotate only half a turn, but also ensures the parallel state between the first horizontal plate 431 and the second horizontal plate 432. The support plate 4210 is used to support the first horizontal plate 431 to prevent it from bending and deforming.

[0041] Two round shafts 437 are rotatably mounted on the bottom of the horizontal plate 431. Round shafts 436 are rotatably mounted on both sides of the horizontal plate 432. The same tension spring 438 is hooked on the adjacent round shafts 436 and 437.

[0042] Furthermore, the tension spring 438 can keep the support plates 431 and 432 taut, and the 432 will not wobble when not subjected to external force.

[0043] Two mounting brackets 45 are fixedly installed on the slider of the electric module 41. Electric push rods 46 are fixedly installed on both mounting brackets 45. The bottom ends of the piston rods of the two electric push rods 46 are fixedly connected to the side of the rectangular plate 421.

[0044] 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.

[0045] The wax injection mechanism 2 includes a base plate 21 fixed to the top of the frame 1. Four guide rods 22 arranged in a rectangular pattern are fixedly installed on the top of the base plate 21. The top of the four guide rods 22 is fixedly installed on the same top plate 23. The same moving plate 25 is slidably sleeved on the four guide rods 22. A cylinder 24 is fixedly installed through the top of the top plate 23. The piston rod end of the cylinder 24 is fixedly connected to the top of the moving plate 25. The molding die 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 moving plate 25. A groove 33 is opened on the top of the lower mold base 31, and a mold core 34 is fixed at the bottom of the groove 33.

[0046] The lower mold base 31 has vent holes 35 and wax inlet holes 36 on both sides that are connected to the mold groove 33. A connector 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. A wax injection head 27 is fixedly installed on the three-axis slide 26.

[0047] Furthermore, 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;

[0048] When the upper mold base 32 and the lower mold base 31 are fitted together, a cavity will be formed between the mold core 34 and the mold groove 33. Then the wax injection head 27 will inject molten wax into the joint 37. The molten wax will enter the cavity through the wax inlet hole 36. During this process, the air in the cavity will be discharged through the vent hole 35.

[0049] Both the lower mold base 31 and the mold core 34 are equipped with water cooling channels. As the cooling water flows through the water cooling channels, it can accelerate the solidification of the molten wax in the cavity to form a box lid wax mold 52.

[0050] After the box lid wax mold 52 is formed, the upper mold base 32 drives the mold core 34 to move upward and separate from the box lid wax mold 52. At this time, the box lid wax mold 52 still stays in the mold groove 33. Then the adsorption mechanism 44 can take out the box lid wax mold 52 in the mold groove 33.

[0051] In this embodiment: when removing the box lid wax mold 52 formed in the molded groove 33, the two adsorption mechanisms 44 are moved to directly above the two box lid wax molds 52. Then, the two adsorption mechanisms 44 are controlled to descend, so that the mold box 442 enters the box lid wax mold 52 and the circular plate 441 abuts against the end face 521. Then, air is evacuated from the mold box 442 through the two rigid conduits 443, so that the box lid wax mold 52 is tightly adsorbed and connected to the adsorption mechanism 44. At this time, the shape of the part removal assembly 4 is as follows. Figure 4 , Figure 5As shown;

[0052] Then, control the two adsorption mechanisms 44 to rise, causing the wax mold 52 of the box lid to separate from the groove 33. Then, start the reduction motor 425 to drive gear 424 to rotate. Gear 424 pulls the two horizontal plates 431 closer together via two racks 423. At this time, the two adsorption mechanisms 44 will synchronously approach each other. During the above process, as gear 435 meshes with the corresponding rack 439, gear 435 will drive the rotating shaft 434 to rotate. The rotating shaft 434 will then drive the horizontal plate 432 to rotate, causing the horizontal plate 432 to rotate half a revolution from bottom to top. At this time, the shape of the part-removing assembly 4 is as follows: Figure 8 As shown;

[0053] Then, the electric module 41 drives the box lid wax molds 52 on the two adsorption mechanisms 44 to move to the top of the operating table 11. The staff can then pick up the box lid wax molds 52 on the adsorption mechanism 44. During this process, the wax injection mechanism 2 and the molding mold 3 work together to form the next box lid wax mold 52.

[0054] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
