Description

Technical Field

[0001] The utility model relates to the technical field of metal processing, in particular to a metal processing spin casting device. Background Art

[0002] Metalworking, also known as metalworking, is the process of shaping metal materials into objects, parts, and components. These range from large components like bridges and ships to minute components like engines, jewelry, and watches. It is widely used in science, industry, art, and crafts. Metalworking methods and processes include casting, plastic forming, and solid forming.

[0003] Among them, during the metal processing and casting process, a spin casting device is used to fill the molten alloy liquid into the high-speed rotating mold under the action of centrifugal force to form the required metal shape.

[0004] However, when the existing technology is actually used, in the process of using a spin casting device to fill the molten alloy liquid into the high-speed rotating mold under the action of centrifugal force, the molten alloy liquid is prone to heat loss when it is added to the mold. When the heat of the alloy liquid is lost, the fluidity of the alloy liquid will decrease accordingly, resulting in the alloy liquid easily remaining in the mold channel when it is filled into the mold through centrifugal rotation, and not being completely filled into the mold, resulting in incomplete metal parts to be processed. Utility Model Content

[0005] The purpose of the present utility model is to provide a metal processing spin casting device to solve the problem raised in the above background technology that in the process of using a spin casting device to fill the molten alloy liquid into the interior of a high-speed rotating mold under the action of centrifugal force, the molten alloy liquid is prone to heat loss when it is added to the interior of the mold. When the heat of the alloy liquid is lost, the fluidity of the alloy liquid will decrease accordingly, resulting in the alloy liquid easily remaining in the mold channel when it is filled into the mold through centrifugal rotation, and not being completely filled into the interior of the mold, resulting in incomplete problems in the metal parts to be processed.

[0006] In order to achieve the above-mentioned purpose, the present utility model provides the following technical solutions: comprising a fixed base plate and a main body mounting frame;

[0007] A driving motor is fixedly installed at the lower side end of the main body mounting frame, a first pulley is fixedly installed on the transmission shaft portion at the lower end of the driving motor, the first pulley is connected to the second pulley through a belt transmission, a transmission shaft is fixedly installed in the middle of the second pulley, the upper top end of the transmission shaft passes through the middle of the main body mounting frame and a lower mold is fixedly installed, an upper mold is fixedly installed on the upper end of the lower mold, and a liquid injection port for injecting alloy liquid into between the lower mold and the upper mold is opened through the middle of the upper end of the upper mold;

[0008] An electric telescopic rod is fixedly installed on the middle part of the top of the main body mounting frame, a mounting plate is fixedly installed on the telescopic part of the lower top of the electric telescopic rod, limiting sliding rods are fixedly installed on both sides of the upper surface of the mounting plate, and a flame nozzle is fixedly installed through the lower end of the mounting plate.

[0009] Preferably, fixing holes are provided through the four corners of the fixed base plate, and there are four fixing holes, which are symmetrically distributed at the four corners of the fixed base plate, so that the fixed base plate can be installed and fixed by connecting bolts through the fixing holes.

[0010] Preferably, the main body mounting frame is fixedly installed on the upper end of the fixed base plate, so that the main body mounting frame is fixedly supported by the fixed base plate.

[0011] Preferably, the middle portion of the transmission shaft is rotatably connected to the middle portion of the lower end of the main mounting frame via a bearing seat support.

[0012] Preferably, there are two limiting slide bars, which are symmetrically distributed on both sides of the upper end surface of the mounting plate, and the upper ends of the limiting slide bars are passed through and movably connected to both sides of the upper end of the main mounting frame.

[0013] Preferably, there are several flame spray heads, which are rotationally symmetrically distributed around the lower end of the mounting plate.

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

[0015] 1. The utility model controls the flame nozzle to heat the upper end of the upper mold when the lower mold and the upper mold rotate. When the upper end of the upper mold is heated, the alloy liquid injected between the lower mold and the upper mold will maintain high temperature and fluidity, thereby realizing the spin casting of metal parts while keeping the alloy liquid at high temperature and fluidity, thus avoiding the temperature loss of the alloy liquid after injection into the mold.

[0016] 2. The utility model also controls the electric telescopic rod to be turned on, and the extension and contraction of the lower top of the electric telescopic rod will drive the mounting plate to move up and down. When the mounting plate moves up and down, it will drive the limit slide bar to move linearly up and down along both sides of the upper end surface of the mounting plate, so that the limit slide bar can play a linear limiting role in the up and down movement of the mounting plate. When the mounting plate moves linearly up and down, it will drive the flame nozzle to move linearly up and down for adjustment. When the flame nozzle moves linearly downward for adjustment, it can increase the heating efficiency of the flame nozzle. When the flame nozzle moves linearly upward for adjustment, it can play a role in mobile storage, thereby preventing the flame nozzle from blocking the injection of alloy liquid and the opening of the upper mold, thereby achieving the spin-cast alloy liquid always maintaining high temperature and fluidity, and playing a role in adjusting the distance between the flame nozzle and the upper mold.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-3 The utility model provides a technical solution: including a fixed base plate 1 and a main body mounting frame 2, the fixed base plate 1 is provided with fixing holes 3 at four corners, and the number of the fixing holes 3 is four, respectively symmetrically distributed at the four corners of the fixed base plate 1, so that the fixed base plate 1 is fixed and fixed by the fixing holes 3 and the connecting bolts, and the main body mounting frame 2 is fixedly installed on the upper end of the fixed base plate 1, so that the main body mounting frame 2 is fixedly supported by the fixed base plate 1;

[0023] The lower side end of the main mounting frame 2 is fixedly installed with a driving motor 4, and the transmission shaft part of the lower end of the driving motor 4 is fixedly installed with a first pulley 5. The first pulley 5 is connected to the second pulley 6 through a belt transmission. The middle of the second pulley 6 is fixedly installed with a transmission shaft 7, and the middle part of the transmission shaft 7 is rotatably connected to the middle of the lower end of the main mounting frame 2 through a bearing seat. The top end of the transmission shaft 7 passes through the middle of the main mounting frame 2 and is fixedly installed with a lower mold 8. The upper end of the lower mold 8 is fixedly installed with an upper mold 9. The middle of the upper end of the upper mold 9 is penetrated by a liquid injection port 14 for injecting alloy liquid into the space between the lower mold 8 and the upper mold 9, so that when the alloy liquid is injected into the space between the lower mold 8 and the upper mold 9 through the liquid injection port 14, When the driving motor 4 is turned on by control, when the driving motor 4 is turned on, it will drive the first pulley 5 to rotate. When the first pulley 5 rotates, it will drive the second pulley 6 to rotate through the belt. When the second pulley 6 rotates, it will drive the transmission shaft 7 to rotate. When the transmission shaft 7 rotates, it will drive the lower mold 8 and the upper mold 9 to rotate. When the lower mold 8 and the upper mold 9 rotate, the alloy liquid injected between the lower mold 8 and the upper mold 9 will be filled into the mold cavity of the lower mold 8 and the upper mold 9 under the action of the centrifugal force of rotation. When the alloy liquid is filled into the mold cavity of the lower mold 8 and the upper mold 9, the alloy liquid is naturally cooled and solidified, and the spin casting processing effect of the required metal part can be achieved;

[0024] The upper end of the limit slide 12 is passed through and fitted on both sides of the upper end surface of the main body mounting frame 2, and a flame nozzle 13 is passed through and fixedly installed on the lower end of the mounting plate 11, and the number of the flame nozzles 13 is respectively distributed symmetrically with the lower end of the mounting plate 11. When the lower mold 8 and the upper mold 9 rotate, the flame nozzle 13 is controlled to open and heat the upper end of the upper mold 9. When the upper end of the upper mold 9 is heated, the alloy liquid injected into the lower mold 8 and the upper mold 9 will maintain high temperature and fluidity, thereby realizing the spin casting of the metal parts, and the spin casting alloy liquid can always maintain high temperature and fluidity, thereby avoiding the temperature loss of the alloy liquid after being injected into the mold.

[0025] At the same time, when the electric telescopic rod 10 is controlled to be turned on, the extension and contraction of the lower top of the electric telescopic rod 10 will drive the mounting plate 11 to move up and down. When the mounting plate 11 moves up and down, it will drive the limiting slide bar 12 to move linearly up and down along both sides of the upper end surface of the mounting plate 11, so that the limiting slide bar 12 can play a linear limiting role in the up and down movement of the mounting plate 11. When the mounting plate 11 moves linearly up and down, it will drive the flame nozzle 13 to move linearly up and down for adjustment. When the flame nozzle 13 moves linearly downward for adjustment, it can increase the heating efficiency of the flame nozzle 13. When the flame nozzle 13 moves linearly upward for adjustment, it can play a role in mobile storage, avoiding the flame nozzle 13 blocking the injection of the alloy liquid and the opening of the upper mold 9, thereby achieving the spin-cast alloy liquid always maintaining high temperature and fluidity, and playing a role in adjusting the distance between the flame nozzle 13 and the upper mold 9.
