Description

Technical Field

[0001] This utility model belongs to the field of casting technology, and in particular relates to a casting melting and pouring device for machining high-hardness machine tool casting bases. Background Technology

[0002] Casting is a process in which liquid metal is poured into a mold cavity that conforms to the shape of the part, and after cooling and solidification, a blank or part is obtained. Machine tool bases are usually integrally formed by casting. When pouring molten metal into the mold, a storage tank is usually used to pour it directly into the mold. However, during the pouring process, it is not easy to control the flow rate of the molten metal, which causes the high-speed flowing molten metal to form turbulence in the cavity, resulting in gas not being able to be discharged in time, thus forming porosity defects. A casting structure that facilitates the control of the flow rate of molten metal is proposed. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a casting, melting, and pouring device for machining high-hardness machine tool casting bases, thus solving the aforementioned problems.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a casting and melting device for machining high-hardness machine tool casting bases, comprising a liquid collecting cylinder, multiple liquid collecting cylinders being horizontally slidably mounted on a frame, the diameter of the through holes at the bottom of the multiple liquid collecting cylinders decreasing sequentially, and the central axes of the multiple liquid collecting cylinders being in the same vertical plane, the frame being vertically slidably mounted on a machine frame, and a liquid storage tank being mounted on the machine frame, with the central axes of the middle liquid collecting cylinder and the liquid storage tank being in the same vertical plane; further comprising a connecting assembly for connecting the multiple liquid collecting cylinders; and an adjusting assembly for adjusting the tilt angle of the liquid storage tank.

[0005] Beneficial effects

[0006] This utility model provides a casting, melting, and pouring device for machining high-hardness machine tool casting bases, which has the following advantages compared with the prior art:

[0007] The user places the mold below the liquid collection cylinder, ensuring its inlet is directly below the central collection cylinder. The user then starts motor A, causing the base plate to rotate counter-clockwise at a constant speed. During this process, the ratchet's counter-clockwise rotation pushes open the limiting plate engaged with its teeth, causing the abutment cylinder to rotate counter-clockwise. However, if the ratchet reverses direction, the abutment cylinder, positioned below the limiting plate, can limit its rotation, preventing it from disengaging from the ratchet. The limiting plate then locks onto the ratchet, preventing it from reversing. As the storage tank rotates upwards, the central axis of the storage tank and the central collection cylinder are in the same vertical plane, allowing the molten metal in the storage tank to flow into the collection cylinder. The molten metal then collects in the collection cylinder and flows uniformly into the mold below through the bottom through-hole. To adjust the flow rate of the molten metal into the mold, the user pulls the limiting plate upwards and reverses motor A, thus adjusting the flow rate of the storage tank. The liquid tank is reset, and then the turntable is rotated. At this time, the lead screw begins to rotate at a constant speed, causing the threaded support plate on it to slide horizontally at a constant speed until the central axis of the second liquid collecting cylinder is on the same horizontal line as the central axis of the liquid storage tank. Since the diameter of the through holes at the bottom of the multiple liquid collecting cylinders decreases sequentially, the molten metal in the liquid storage tank can be poured into the liquid collecting cylinder at a certain speed. This can regulate the outflow speed of the molten metal in the liquid collecting cylinder, thereby avoiding the formation of turbulence in the cavity by the high-speed flowing molten metal, which would prevent gas from being discharged in time and thus form porosity defects. During this process, if the level of molten metal collected in the liquid collecting cylinder is high, the user can start the motor, causing the lead screw A, which is fixedly connected to its output shaft, to rotate at a constant speed. At this time, the guide plate begins to slide upward along its connection with the frame, thereby shortening the vertical distance between the liquid collecting cylinder and the liquid storage tank, reducing the impact force of the molten metal flowing out of the liquid storage tank, and preventing the molten metal in the liquid storage tank from impacting the liquid surface in the liquid collecting cylinder when it flows out of the liquid storage tank, which would cause the molten metal to splash.

Detailed Implementation

[0013] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0014] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0015] Please see Figures 1-4 This invention provides a casting and melting device for processing a high-hardness machine tool casting base, comprising a liquid collecting cylinder 202, multiple liquid collecting cylinders 202 being horizontally slidably disposed on a frame 201, the diameter of the through holes at the bottom of the multiple liquid collecting cylinders 202 decreasing sequentially, and the central axes of the multiple liquid collecting cylinders 202 being in the same vertical plane, the frame 201 being vertically slidably disposed on a machine frame 101, and a liquid storage tank 203 being disposed on the machine frame 101, and the central axes of the middle liquid collecting cylinder 202 and the liquid storage tank 203 being in the same vertical plane;

[0016] It also includes a connecting assembly for connecting multiple liquid collection cylinders 202; and an adjusting assembly for adjusting the tilt angle of the liquid storage tank 203.

[0017] For the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific liquid collecting cylinder 202 described in the above embodiments. For example, both the liquid collecting cylinder 202 and the liquid storage tank 203 are made of carbon steel with a certain thickness. The purpose of this setting is that the melting point of carbon steel is 1425-1540℃, thereby avoiding the impact of high-temperature casting liquid on the liquid collecting cylinder 202 and the liquid storage tank 203.

[0018] Specifically, the connecting assembly includes a tray 204 and a slide rod 205. A plurality of liquid collecting cylinders 202 are symmetrically fixedly connected to the tray 204, and one side of the tray 204 is slidably connected to the slide rod 205. The slide rod 205 is fixedly connected to the frame 201.

[0019] It also includes a drive assembly for sliding the tray 204 horizontally.

[0020] Specifically, the drive assembly includes a lead screw 206, which is rotatably connected to the frame 201, and the support plate 204 is threadedly connected to the lead screw 206. One end of the lead screw 206 extends through the frame 201, and a turntable 207 is fixedly connected thereto.

[0021] It also includes splash-proof components to prevent molten metal from splashing out of the collection tank 202.

[0022] For the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific lead screw 206 described in the above embodiments. For example, the lead screw 206 should be a lead screw with a self-locking effect. The purpose of this setting is to facilitate the increase of the limiting effect on the threaded support plate 204 on it.

[0023] Specifically, the adjustment assembly includes a base plate 208 and a motor A209. The base plate 208 is rotatably connected to the frame 101, and the liquid storage tank 203 is fixedly connected to the base plate 208. One side of the base plate 208 is fixedly connected to the output shaft of the motor A209, and the motor A209 is fixedly connected to the frame 101.

[0024] It also includes a positioning component for limiting the rotation of the base plate 208.

[0025] For the above examples, those skilled in the art should know that when implementing the above technical solutions, it is not limited to the specific motors A209 and 303 described in the above embodiments. For example, both motors A209 and 303 are motors with self-locking effect. The purpose of this setting is to prevent the output shaft from reversing if an external force is applied to it when it stops and enters the standby state.

[0026] Specifically, the positioning component includes a ratchet 304 and a limiting plate 305. The other side of the base plate 208 is fixedly connected to the axis of the ratchet 304, and the limiting plate 305 is engaged on the teeth of the ratchet 304. The end of the limiting plate 305 away from the ratchet 304 is rotatably connected to the frame 101.

[0027] Specifically, a stop cylinder 306 is attached below the limiting plate 305. The stop cylinder 306 is fixedly connected to the frame 101, and the stop cylinder 306 is close to the circumference of the ratchet 304.

[0028] For the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific limiting plate 305 and the abutment 306 described in the above embodiments. For example, the limiting plate 305 and the abutment 306 are both made of high-hardness steel. The purpose of this arrangement is to facilitate the avoidance of breakage under stress.

[0029] Specifically, the splash-proof assembly includes a guide plate 301 and a lead screw A302. One side of the guide plate 301 is fixedly connected to the frame 201, and the other side of the guide plate 301 is threadedly connected to the lead screw A302. The lead screw A302 is rotatably connected to the frame 101.

[0030] It also includes a transmission assembly for making the lead screw A302 rotate at a constant speed.

[0031] Specifically, the transmission assembly includes a motor 303, the output shaft of which is fixedly connected to a lead screw A302, and the motor 303 is fixedly connected to the frame 101.

[0032] In this embodiment of the invention, the user places the mold below the liquid collection cylinder 202, with its inlet directly below the middle liquid collection cylinder 202. The user then starts the motor A209, at which point the base plate 208 begins to rotate counterclockwise at a uniform speed. During this process, as the ratchet 304 rotates counterclockwise synchronously, it pushes open the limiting plate 305 that overlaps its teeth, causing the abutment cylinder 306 to rotate counterclockwise. However, if the ratchet 304 reverses direction, the abutment cylinder 306, being below the limiting plate 305, can limit the rotation of the limiting plate 305, thereby preventing... When the limiting plate 305 disengages from the ratchet 304, the limiting plate 305 is now locked onto the ratchet 304, preventing the ratchet 304 from reversing. During the upward rotation of the liquid storage tank 203, since the central axis of the liquid storage tank 203 and the central collecting cylinder 202 are in the same vertical plane, the molten metal in the liquid storage tank 203 can flow into the collecting cylinder 202. The molten metal then collects in the collecting cylinder 202 and flows uniformly into the mold below through the through-hole at its bottom. When it is necessary to adjust the speed at which the molten metal flows into the mold, the user pulls the limiting plate 305 upwards and activates the electric... Machine A209 reverses, thus resetting the liquid storage tank 203. Then, the turntable 207 rotates, causing the lead screw 206 to rotate at a constant speed. This causes the threaded support plate 204 to slide horizontally and at a constant speed until the second collecting cylinder 202 is aligned with the central axis of the liquid storage tank 203. Since the diameters of the bottom through holes in the multiple collecting cylinders 202 decrease sequentially, the molten metal in the liquid storage tank 203 can be poured into the collecting cylinder 202 at a constant speed. This regulates the outflow speed of the molten metal in the collecting cylinder 202, thereby preventing turbulence caused by the high-speed flowing molten metal within the mold cavity. This prevents gas from being discharged in time, resulting in porosity defects. During this process, if the level of molten metal collected in the collecting cylinder 202 is high, the user can start the motor 303, causing the lead screw A302, which is fixedly connected to its output shaft, to rotate at a constant speed. At this time, the guide plate 301 begins to slide upward along its connection with the frame 101, thereby shortening the vertical distance between the collecting cylinder 202 and the storage tank 203, reducing the impact force of the molten metal flowing out of the storage tank 203, and preventing the molten metal from impacting the liquid surface in the collecting cylinder 202 when it flows out of the storage tank 203, thus preventing the molten metal from splashing.

[0033] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0034] The term "fixed connection" as used in this application refers to a connection in which parts or components are fixed without any relative movement. This includes both detachable and non-detachable connections.

[0035] (1) Detachable connection: The components are fixed together using screws, splines, wedges, etc. This type of connection can be disassembled during maintenance without damaging the parts. However, the specifications of the connecting parts used must be correct (such as the length of the bolts, keys, wedges) and properly tightened.

[0036] (2) Non-removable connections: These mainly refer to welding, riveting, and tenon joints. Since disassembly requires forging, sawing, or oxyacetylene cutting for repair or replacement, the parts generally cannot be reused. At the same time, attention should be paid to process quality, technical inspection, and remedial measures (such as correction and polishing) during connection.

[0037] The sliding connection referred to in this application means that the component can slide along a linear trajectory, and the hinge referred to in this application means that the component can rotate along an axial constraint.

[0038] In some cases, the sliding connection and hinge referred to in this application may also be damped, enabling the component to maintain in the desired position.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
