Description

Technical Field

[0001] The utility model relates to the technical field of quartz crucible demoulding, in particular to an automatic demoulding device for a quartz crucible. Background Art

[0002] A quartz crucible is a vessel made of quartz sand as the main material. It has the advantages of high purity, strong temperature resistance, and stable quality. It is used more and more widely. During production, the quartz crucible needs to be placed in a graphite mold for molding, so it needs to be demolded after molding.

[0003] However, when the existing quartz crucible is taken out of the mold, it is usually necessary to manually knock the outer wall of the rotating mold for multiple times. Since the strength of each manual knock is different, the force on the mold is not uniform, so that the quartz crucible in the mold is still adhered to the mold, which makes it difficult to take out the crucible. In addition, when the crucible is taken out of the mold, it is usually manually clamped with a special crucible clamping pliers to clamp the upper mouth of the quartz crucible and drag the crucible out of the mold. Since the contact area between the pliers and the upper mouth of the crucible is small, the force during dragging is concentrated on the smaller position of the upper mouth of the quartz crucible, so that the crucible is easily crushed during dragging, which is not conducive to maintaining the integrity of the quartz crucible when it is taken out.

[0014] 2. The automatic demoulding device for quartz crucible, through the cartridge, bracket, side frame and slider, allows the quartz crucible to be taken out from the mold by extending the cartridge whose outer diameter matches the inner diameter of the crucible into the crucible, so that the outer wall of the cartridge is in close contact with the inner wall of the crucible, and then the crucible is pulled out from the mold, so that the force-bearing surface of the quartz crucible is larger when it is taken out from the mold, reducing the probability of the quartz crucible being crushed when it is taken out, and being more conducive to maintaining the integrity of the quartz crucible when it is taken out.

[0023] like Figures 1 to 4 As shown, the automatic demoulding device for quartz crucible in this embodiment includes a sleeve pot 3, a mold 2 is provided inside the sleeve pot 3, a crucible 1 is movably embedded inside the mold 2, rubber balls 4 are provided on both sides of the sleeve pot 3, a rocker 5 is fixedly connected to the bottom end of the rubber ball 4, a rotary shaft 15 is movably connected to the bottom end of the rocker 5, a bottom frame 12 is provided at the bottom of the sleeve pot 3, a forward and reverse motor 13 is provided on one side of the bottom frame 12, a side frame 9 is fixedly connected to the middle of the bottom frame 12, a slider 11 is provided at the bottom of the side frame 9, a bracket 8 is fixedly connected to the top of the slider 11, a cartridge 7 is fixedly connected to one end of the bracket 8, and an electric push rod 10 is fixedly installed on the top of the side frame 9.

[0024] Specifically, the height of the pot sleeve 3 is half of the height of the mold 2, so that the rubber ball 4 on the top of the pot sleeve 3 can touch the top of the outer wall of the mold 2, thereby realizing the rubber ball 4 knocking on the outer wall of the mold 2. The mold 2 is a mold 2 for making a quartz crucible 1, and is made of graphite. It is hard and resistant to high temperature and can withstand the knocking of the rubber ball 4. The rubber ball 4 is a solid structure and is not easily deformed after frequent knocking, making the rubber ball 4 more durable. The function of the swing rod 5 is to increase the swing amplitude of the rubber ball 4, so that the rubber ball 4 can knock on the outer wall of the mold 2 with the force generated by the swing rod 5. The function of the rotating shaft 15 is to enable the swing rod 5 to swing with the left and right swing of the pot sleeve 3 on the bottom frame 12, so that the swing rod 5 has a certain swing amplitude, so that the rubber ball 4 at the top of the swing rod 5 also swings left and right due to inertia, thereby realizing the knocking on the outer wall of the mold 2. The bottom frame 12 is " The cam 12 is provided with a plurality of movable members 14, 16 and 17 for supporting the mould 2. The movable members 14 are provided with a plurality of movable members 16 for supporting the mould 2. The movable members 14 are provided with a plurality of movable members 17 for supporting the mould 2. The movable members 14 are provided with a plurality of movable members 17 for supporting the mould 2. The movable members 14 are provided with a plurality of movable members 17 for supporting the mould 2.

[0025] Furthermore, a rotating motor 18 is fixedly installed at the bottom end of the pot sleeve 3, and the bottom end of the mold 2 is engaged with the output end of the rotating motor 18. The mold 2 is movably connected to the pot sleeve 3 through the rotating motor 18. The rotating motor 18 can drive the mold 2 to rotate in the pot sleeve 3, so that the rubber ball 4 can knock on different positions of the same horizontal height of the outer wall of the mold 2, which is more conducive to the separation of the crucible 1 and the mold 2, thereby reducing the difficulty of taking the crucible 1 out of the mold 2.

[0026] Furthermore, the tops of both side walls of the pot sleeve 3 are fixedly connected with a clamping plate 6, the rotating shaft 15 is movably connected to the clamping plate 6, and the rubber ball 4 is movably connected to the pot sleeve 3 through the rocker 5 and the clamping plate 6. The function of the clamping plate 6 is to support the rotating shaft 15, so that the rotating shaft 15 can drive the rocker 5 to swing on the side wall of the pot sleeve 3, thereby realizing the rubber ball 4 knocking on the pot sleeve 3.

[0027] Furthermore, both side walls of the top of the pot sleeve 3 are fixedly connected with clamping shafts 19, and the two clamping shafts 19 are movably connected to the top of the base frame 12. The pot sleeve 3 is movably connected to the base frame 12 through the clamping shafts 19. The clamping shafts 19 can enable the pot sleeve 3 to swing left and right on the top of the base frame 12, and at the same time, the pot sleeve 3 can flip the mold 2 to a horizontal position, which is convenient for the subsequent removal of the crucible 1.

[0028] Furthermore, one end of one of the clamping shafts 19 is sleeved with a first gear 16, and the outer wall of the first gear 16 is meshed with a second gear 17, and the output end of the forward and reverse motor 13 is connected with the second gear 17 through the meshing of the first gear 16 and the second gear 17 to enable the clamping shaft 19 to drive the pot sleeve 3 to swing left and right, so that the pot sleeve 3 is more controllable when swinging.

[0029] Furthermore, a sleeve 14 is installed on one side of the base frame 12, and the forward and reverse motor 13 is installed on the front side of the sleeve 14. The first gear 16 and the second gear 17 are both located in the sleeve 14. The sleeve 14 can cover the first gear 16 and the second gear 17 to ensure that the gear teeth of the first gear 16 and the second gear 17 can mesh smoothly.

[0030] Furthermore, the output end of the electric push rod 10 is engaged with the end of the bracket 8 away from the cartridge 7, the slider 11 is slidably connected to the side frame 9 through the bracket 8, and the cartridge 7 is movably connected to the crucible 1 through the electric push rod 10. The slider 11 can slide along the side frame 9 under the push of the bracket 8, thereby driving the cartridge 7 to move toward the position of the crucible 1, thereby achieving close contact with the crucible 1.

[0031] The method of using the present embodiment is as follows: before using the automatic demoulding device for the quartz crucible 1, the present device needs to be connected to an external power supply first, and then the forward and reverse motor 13 is started. At this time, the motor will drive the second gear 17 to rotate forward, so that the second gear 17 meshes with the first gear 16 to rotate forward, and drives the clamping shaft 19 on the first gear 16 to rotate forward on the bottom frame 12, and then the motor is controlled to reverse, so that the clamping shaft 19 rotates in the opposite direction. At this time, the pot sleeve 3 will swing left and right on the bottom frame 12, driving the rotating shaft 15 to rotate on the clamping plate 6, prompting the swing rod 5 to swing left and right on the top of the pot sleeve 3, and driving the rubber ball 4 to swing on the outer wall of the mold 2. When the rubber ball 4 swings to a position that fits the outer wall of the mold 2, it will knock on the outer wall of the mold 2, and then the rotating motor 18 is started to drive the mold 2 to rotate in the pot sleeve 3. The position where the rubber ball 4 strikes changes, so that the outer wall of the mold 2 is evenly subjected to the force of the strike. At this time, the quartz crucible 1 in the mold 2 will be separated from the mold 2. Then the forward and reverse motors 13 can be controlled to drive the sleeve pot 3 to rotate to a horizontal position, so that the openings of the mold 2 and the crucible 1 face the direction of the side frame 9. Then the electric push rod 10 is started, so that the electric push rod 10 pushes the bracket 8 to slide on the side frame 9 through the slider 11, and drives the cartridge 7 to move toward the opening of the quartz crucible 1 in the mold 2. When the cartridge 7 extends into the interior of the mold 2, the inner wall of the quartz crucible 1 will be tightly attached to the outer wall of the cartridge 7. Then the electric push rod 10 can be controlled to retract, so that the bracket 8 slides back. At this time, since the quartz crucible 1 is separated from the mold 2, when the cartridge 7 is pulled out of the mold 2, the quartz crucible 1 will also be pulled out of the mold 2 with the cartridge 7.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
