Description

Technical Field

[0001] This utility model relates to a wax mold forming device for castings, specifically a wax mold forming device for stainless steel precision castings with multi-heat-section thin-walled double-layer flow tubes, belonging to the field of precision casting technology. Background Technology

[0002] Double-layer flow tubes are widely used in high-end industrial fields, with applications mainly focusing on energy transmission, semiconductor manufacturing, and precision hydraulic systems. In oil and gas transmission, their double-layer structure achieves leak-proof design through the inner layer conveying the medium and the outer layer providing vacuum protection, effectively ensuring the safety of long-distance pipelines. Double-layer flow tubes can be produced through precision casting. In the precision casting process, a wax model of the double-layer flow tube needs to be made first. The wax model can be rapidly formed using a 3D printer. The 3D printer is equipped with a cantilever control box to set and control the printer parameters.

[0003] However, the height of the control box on a traditional 3D printer is fixed, so operators of all heights need to change their body shape significantly when operating it, which can easily cause discomfort and result in poor user comfort. Utility Model Content

[0004] The purpose of this invention is to provide a wax mold forming device for stainless steel precision casting of multi-heat-section thin-walled double-layer flow tubes in order to solve the above problems. The device can adjust the height of the control box according to the different heights of the operators, so that the operators can operate at a suitable height, avoiding the need to change their body shape significantly, and effectively improving the comfort of operation.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a wax mold forming device for stainless steel precision casting of multi-heat-section thin-walled double-layer flow pipe, comprising a 3D printer body, characterized in that: a cantilever is installed on the 3D printer body, a connecting sleeve is slidably connected to the cantilever, a control box is provided at the end of the connecting sleeve, a fixing structure is provided on the control box, an adjustment structure is provided on the cantilever, the adjustment structure includes a first connecting seat and a motor, a first connecting seat is fixedly connected to the cantilever, a lead screw is rotatably connected to the first connecting seat, a second connecting seat is fixedly connected to the connecting sleeve, a threaded sleeve is fixedly connected to the second connecting seat, and the threaded sleeve and the lead screw are threadedly connected.

[0006] Preferably, a motor is mounted on the top side of the first connecting seat, and the output shaft of the motor is fixedly connected to the top end of the lead screw.

[0007] Preferably, a protective cover is fixedly connected to the bottom side of the first connecting seat, and the top end of the threaded sleeve extends into the interior of the protective cover.

[0008] Preferably, the fixing structure includes a locking block and a protrusion, and two locking blocks are slidably connected on the control box. The two locking blocks engage with the same connecting sleeve, and the bottom end of the connecting sleeve engages with the control box.

[0009] Preferably, a protrusion is fixedly connected to the card block, and a spring abuts against the protrusion and the control box.

[0010] Preferably, a turntable is rotatably connected to the control box, the turntable has two guide grooves, a guide shaft is fixedly connected to the locking block, and the guide shaft extends into the interior of the adjacent guide groove and is slidably connected to the turntable.

[0011] Preferably, a handle is fixedly connected to the top side of the turntable, and the handle is perpendicular to the turntable.

[0012] Preferably, the cross-section of the card block near the connecting sleeve is trapezoidal, and the two guide grooves are arranged in a circular array about the middle of the turntable.

[0013] The beneficial effects of this utility model are as follows: When the height of the control box needs to be adjusted, the screw can be rotated. Since the screw and the threaded sleeve are connected by a thread, the threaded sleeve will drive the second connecting seat to move as the screw rotates. The second connecting seat will drive the connecting sleeve to slide on the cantilever, and the connecting sleeve will drive the control box to move, thereby realizing the adjustment of the height of the control box. Therefore, the height of the control box can be adjusted according to the operator's height, so that the operator can operate at a height that suits him / her, avoiding the need to change the body shape significantly, and effectively improving the comfort of operation.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, a wax mold forming device for a multi-heat-section thin-walled double-layer flow pipe stainless steel precision casting includes a 3D printer body 1, a cantilever 2 mounted on the 3D printer body 1, a connecting sleeve 3 slidably connected to the cantilever 2, a control box 4 at the end of the connecting sleeve 3, a fixing structure 6 on the control box 4, and an adjustment structure 5 on the cantilever 2. The adjustment structure 5 includes a first connecting seat 501 and a motor 502. The first connecting seat 501 is fixedly connected to the cantilever 2, and a lead screw 503 is rotatably connected to the first connecting seat 501. A second connecting seat 505 is fixedly connected to the connecting sleeve 3, and a threaded sleeve 504 is fixedly connected to the second connecting seat 505. The threaded sleeve 504 and the lead screw 503 are threadedly connected.

[0022] As a technical optimization solution of this utility model, such as Figure 4 As shown, a motor 502 is installed on the top side of the first connecting seat 501, so the motor 502 can control the rotation of the lead screw 503, thereby realizing the rapid adjustment of the height of the control box 4.

[0023] As a technical optimization solution of this utility model, such as Figure 2 and Figure 4 As shown, a protective cover 506 is fixedly connected to the bottom side of the first connecting seat 501. The protective cover can shield and protect the lead screw 503, thereby preventing the lead screw 503 from being damaged by impact and effectively improving the safety of use.

[0024] As a technical optimization solution of this utility model, such as Figure 2 , Figure 3, Figure 4 and Figure 5 As shown, the fixing structure 6 includes a locking block 604 and a protrusion 605. Two locking blocks 604 are slidably connected to the control box 4. The two locking blocks 604 are engaged with the same connecting sleeve 3. By engaging the two locking blocks 604 with the connecting sleeve 3 at the same time, the control box 4 can be prevented from falling off the connecting sleeve 3, thereby fixing the control box 4.

[0025] As a technical optimization solution of this utility model, such as Figure 3 As shown, a protrusion 605 is fixedly connected to the locking block 604, and a spring 606 abuts against the control box 4. Under the action of the spring blade 606, the locking block 604 can always be engaged with the connecting sleeve 3.

[0026] As a technical optimization solution of this utility model, such as Figure 3 and Figure 4 As shown, a turntable 601 is rotatably connected to the control box 4. The turntable 601 is provided with two guide grooves 602. A guide shaft 603 is fixedly connected to the locking block 604. By rotating the turntable 601, the two guide grooves 602 can move simultaneously. The simultaneous movement of the two guide grooves 602 will cause the two guide shafts 603 to move simultaneously inside the guide grooves 602, thereby preventing the two locking blocks 604 from engaging with the connecting sleeve 3 at the same time. This facilitates the quick separation of the connecting sleeve 3 from the control box 4 and the quick disassembly of the control box 4.

[0027] As a technical optimization solution of this utility model, such as Figure 2 As shown, a handle 607 is fixedly connected to the top side of the turntable 601. The handle 607 is perpendicular to the turntable 601, and the turntable 601 can be easily rotated by holding the handle 607.

[0028] As a technical optimization solution of this utility model, such as Figure 3 and Figure 5 As shown, the cross-section of the locking block 604 near the connecting sleeve 3 is trapezoidal, so it can play a role in guiding the movement when the locking block 604 and the connecting sleeve 3 are engaged. The two guide grooves 602 are arranged in a circular array about the middle of the turntable 601, so that when the turntable 601 moves in one direction, the two locking blocks 604 can move away from the connecting sleeve 3 at the same time.

[0029] In use, when the height of the control box 4 needs to be adjusted, the motor 502 is started. The output shaft of the motor 502 rotates, driving the lead screw 503 to rotate. Since the lead screw 503 and the threaded sleeve 504 are threadedly connected, as the lead screw 503 rotates, the threaded sleeve 504 drives the second connecting seat 505 to move. The second connecting seat 505 drives the connecting sleeve 3 to slide on the cantilever 2, and the connecting sleeve 3 drives the control box 4 to move, thereby adjusting the height of the control box 4. Therefore, the height of the control box 4 can be adjusted according to the operator's height, allowing the operator to operate at a suitable height and avoiding the need to drastically change body shape for operation. This design effectively improves operational comfort. The protective sleeve 506 shields and protects the lead screw 503, preventing it from being damaged by impact and thus enhancing safety. Furthermore, when the control box 4 is damaged, the handle 607 rotates the turntable 601, causing the two guide grooves 602 to move. Simultaneously, the guide grooves 602 cause the guide shaft 603 to move the locking block 604 away from the connecting sleeve 3, and the spring 606 contracts. When the ends of the two locking blocks 604 are no longer engaged with the connecting sleeve 3, the control box 4 can be removed from the bottom of the connecting sleeve 3, enabling quick disassembly and facilitating maintenance.
