Description

Technical Field

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

[0002] Castings are metal objects obtained by various casting methods, that is, the smelted liquid metal is poured into a pre-prepared mold by pouring, injection, suction or other casting methods, and after cooling and subsequent processing such as grinding, the resulting object has a certain shape, size and performance;

[0003] Castings are generally processed by casting. Casting can be divided into die casting and sand casting according to different processing methods. Die casting refers to injecting molten raw materials into a closed mold through an injection machine, and then pressurizing and cooling the mold to obtain the product after the mold is finalized. Sand casting refers to pouring the raw materials into the mold from an open casting port and waiting for the mold to cool naturally to obtain the product. Sand casting requires manual control of the casting position of the molten raw materials, and has low accuracy.

[0004] However, when the molten raw material of the casting is cast in sand casting, the raw material flows out from the storage tank in an arc and cannot flow directly downward. It is easy to be cast outside the mold, resulting in a waste of raw materials and a safety hazard. Therefore, it does not meet the existing needs. We have proposed a casting device. Utility Model Content

[0005] The utility model aims to provide a casting device to solve the problems proposed in the above-mentioned background technology that when the molten raw materials of the castings are cast in sand casting, the raw materials flow out from the mouth of the storage tank in an arc and cannot flow directly downward, and are easily cast outside the mold, resulting in a waste of raw materials and potential safety hazards.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a casting device, comprising a fixed seat, a storage tank is rotatably installed above the fixed seat, and rotating shafts are fixed on both sides of the top of the storage tank, and the ends of the two rotating shafts pass through the fixed seat and are connected to the fixed seat through ball bearings. A casting port is opened on the front end surface of the storage tank, a casting guide nozzle is fixed in front of the casting port, a guide sleeve is installed below the casting guide nozzle, two hanging plates are fixed on the top of the guide sleeve, a supporting shaft is fixed on the inner side of the top of the hanging plate, and one end of the supporting shaft is rotatably inserted into the outer wall of the casting guide nozzle.

[0007] Preferably, a drainage sleeve is installed at the top of the guide sleeve, the drainage sleeve is in an arc shape and forms an arc-shaped protrusion upward in the middle, and the guide sleeve and the drainage sleeve are formed by integrated casting.

[0008] Preferably, a positioning plug-in plate is fixed to the outer surface of the guide sleeve, and the rear edge of the positioning plug-in plate is bent upward at ninety degrees.

[0009] Preferably, a counterweight block is installed above the positioning plug-in plate, and the counterweight block is slidably plugged between the guide sleeve and the positioning plug-in plate, and the weight of the counterweight block is much greater than the weight of the guide sleeve.

[0010] Preferably, a plurality of drainage strips are distributed in a circular row on the inner side of the guide sleeve, and the drainage strips are spiral-shaped as a whole.

[0011] Preferably, a fixing plate is installed below one end of one of the rotating shafts, the fixing plate is fixed to the fixing seat and a driving motor is fixed on the upper surface, and transmission gears are fixed to the output shaft end of the driving motor and the outer side of the end of the rotating shaft, and the two transmission gears are meshed with each other.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] like Figure 1 and Figure 3 The top of the storage tank 2 is provided with a rotating shaft 4, and the ends of the two rotating shafts 4 pass through the fixed seat 1 and are connected to the fixed seat 1 through ball bearings. A casting port 14 is provided on the front face of the storage tank 2, and a casting guide nozzle 3 is fixed in front of the casting port 14. A guide sleeve 7 is installed below the casting guide nozzle 3, and two hanging plates 9 are fixed on the top of the guide sleeve 7. A supporting shaft 10 is fixed on the inner side of the top of the hanging plate 9, and one end of the supporting shaft 10 is rotatably inserted into the outer wall of the casting guide nozzle 3. When the storage tank 2 rotates around the axis of the rotating shaft 4 and casts the molten raw material, the molten raw material will enter the guide sleeve 7 from the casting guide nozzle 3 and vertically downward from the guide sleeve 7, ensuring that the raw material directly enters the mold and will not be cast outside the mold, avoiding waste during the raw material casting process and ensuring the personal safety of the surrounding staff.

[0022] A fixing plate 6 is installed under one end of one of the rotating shafts 4. The fixing plate 6 is fixed to the fixing seat 1 and a driving motor 5 is fixed on the upper surface. Transmission gears are fixed to the output shaft end of the driving motor 5 and the outer side of the end of the rotating shaft 4. The two transmission gears are meshed with each other, and mechanical power is used to drive the rotating shaft 4 and the storage tank 2, so that the storage tank 2 can be rotated more easily and the raw materials can be poured.

[0023] like Figure 2 and Figure 4As shown, a drainage sleeve 8 is installed at the top of the guide sleeve 7. The drainage sleeve 8 is located in an arc shape and forms an arc-shaped protrusion upward in the middle. The guide sleeve 7 and the drainage sleeve 8 are formed by integrated casting. A positioning plug-in plate 12 is fixed to the outer surface of the guide sleeve 7. The rear edge of the positioning plug-in plate 12 is bent upward at ninety degrees. A counterweight block 11 is installed above the positioning plug-in plate 12. The counterweight block 11 is slidably plugged between the guide sleeve 7 and the positioning plug-in plate 12, and the weight of the counterweight block 11 is much greater than the weight of the guide sleeve 7. The counterweight block 11 is used to increase the weight of the guide sleeve 7 and keep the center of the guide sleeve 7 stable, so that the guide sleeve 7 is always vertically downward during the rotation of the storage tank 2, and then the drainage sleeve 8 is used to drain the raw material flowing out of the casting guide nozzle 3, so that the raw material is concentrated into the guide sleeve 7 and flows out smoothly from the bottom of the guide sleeve 7.

[0024] A plurality of drainage strips 13 are arranged in a circular row on the inner side of the guide sleeve 7. The drainage strips 13 are spirally shaped as a whole. The drainage strips 13 distributed in a spiral shape on the inner wall of the guide sleeve 7 are used to guide the raw materials entering the guide sleeve 7, so that the raw materials gather toward the middle of the guide sleeve 7 and reduce the flow speed of the raw materials, so that when the raw materials leave the bottom of the guide sleeve 7 and enter the mold, they will not splash outwards due to the collision with the mold.

[0025] Working principle: First, the casting raw material is placed in the storage tank 2 and heated, so that the raw material becomes a molten fluid after heating, and then the device is powered on and started. After the drive motor 5 is powered on, it drives the two meshing transmission gears to rotate. At this time, the rotating shaft 4 will drive the storage tank 2 to rotate around its axis. During the rotation process, the molten raw material in the storage tank 2 will leave the storage tank 2 from the casting port 14 and the casting guide nozzle 3. When the raw material flows out from the casting guide nozzle 3, it will first contact the drainage sleeve 8 and enter the guide sleeve 7 along the drainage sleeve 8. On the side, due to the existence of the counterweight 11 at the bottom of the guide sleeve 7, the guide sleeve 7 always remains vertically downward during the rotation of the storage tank 2, so the raw material entering the guide sleeve 7 will flow out of the guide sleeve 7 from the middle of the guide sleeve 7 through the drainage of the drainage strip 13, and the raw material flowing out of the guide sleeve 7 always remains vertically downward. Compared with the traditional casting method, the raw material of the device always remains vertically downward during the casting process, and can enter the mold accurately, avoiding waste of raw materials during the casting process and ensuring the personal safety of surrounding staff.

[0026] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
