Abstract
Description
Technical Field
[0001] This utility model relates to the field of resin sand casting technology, specifically a resin sand top column casting device. Background Technology
[0002] Resin sand is a casting material made primarily of sand and resin. It possesses excellent casting properties and high casting precision, and is widely used in casting production in industries such as automotive, electromechanical, and aerospace. Traditional casting methods rely heavily on manual pouring from sand molds, resulting in low efficiency and inconsistent quality, failing to meet the demands of modern industrial production. Therefore, automated and mechanized pouring devices have gradually evolved. In the top-column pouring process for resin sand, the resin sand needs to be transported within its storage container before pouring. Currently, with top-column pouring, the resin sand stored in the container experiences sedimentation due to gravity, causing heavier particles to settle to the bottom or accumulate, forming a sediment layer. This can lead to blockages or slow discharge during pouring. Simultaneously, resin sand congestion can easily occur at the outlet of the container, hindering rapid discharge and further reducing the efficiency of top-column pouring, directly impacting the effectiveness of the top-column pouring device.
[0003] Therefore, it is necessary to develop a resin sand top column casting device. Utility Model Content
[0004] The purpose of this invention is to provide a resin sand top column casting device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a resin sand top column casting device, comprising a resin sand storage tank, a fixing ring at the bottom of the resin sand storage tank, a top column installed below the fixing ring, and an installation frame installed at the top of the resin sand storage tank.
[0006] A casting and conveying assembly is provided above the outer wall of the top column. The casting and conveying assembly includes a mounting ring, and mounting holes are provided on both sides of the surface of the mounting ring.
[0007] Preferably, a corrugated pipe is installed at the top of the top column, and the top of the corrugated pipe is fixedly connected to the center of the bottom of the fixing ring. A flexible hose is installed at the bottom of the top column, and a secondary pipe is installed at one end of the flexible hose.
[0008] Preferably, a motor is installed at the top center of the mounting bracket, and a rotating shaft is installed at the output end of the motor.
[0009] Preferably, a bracket is installed at the center of the outer wall of the rotating shaft, and the outer wall of the bracket is fixedly connected to the inner wall of the resin sand storage tank.
[0010] Preferably, a stirring paddle is provided on the upper part of the outer wall of the rotating shaft, and an auger is provided on the lower part of the outer wall of the rotating shaft, with the auger located inside the top column.
[0011] Preferably, a guide post is installed inside the mounting hole, and the outer wall of the guide post is slidably connected to the inner wall of the mounting hole.
[0012] Preferably, the top end of the guide post is fixedly connected to the bottom end of the fixing ring, and a nut is threadedly connected to the lower part of the outer wall of the guide post.
[0013] Preferably, a spring is provided on the upper part of the outer wall of the guide column, and a vibration unit is installed on the end face of the outer wall of the mounting ring.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] By sliding the mounting ring on the top column to the outer wall of the guide column on the fixed ring through the mounting hole, and installing the nut on the lower part of the guide column's outer wall with a threaded connection, and using the spring fitted on the outer wall of the guide column, the resin sand in the resin sand storage tank needs to be poured into the hose by using a motor-driven auger. During this process, the vibration unit on the mounting ring, in conjunction with the spring, vibrates the resin sand in the top column and corrugated pipe, minimizing the occurrence of resin sand congestion and slow discharge. During the resin sand discharge process, the motor-driven stirring paddle and auger rotate to ensure orderly discharge of the resin sand.

The top column 2 is installed at the bottom of the fixing ring 101 on the resin sand storage tank 1 using the corrugated pipe 201, and is made to be through-hole so that the resin sand stored in the resin sand storage tank 1 can fall into the corrugated pipe 201 and enter the top column 2. The flexible hose 202 and the secondary pipe 203 on the top column 2 are used for pouring. At the same time, the flexible hose 202 and the secondary pipe 203 extend the pouring range, and the secondary pipe 203 is easy to hold for pouring. A mounting frame 3 is installed on the top of the resin sand storage tank 1. A motor 301 is installed at the top center of the mounting frame 3. A rotating shaft 302 is installed at the output end of the motor 301. A bracket 303 is installed at the center of the outer wall of the rotating shaft 302. The outer wall of the bracket 303 is fixedly connected to the inner wall of the resin sand storage tank 1. A stirring paddle 304 is installed above the outer wall of the rotating shaft 302. An auger 305 is installed below the outer wall of the rotating shaft 302. The auger 305 is located inside the top column 2. The motor 301 is installed on the top of the mounting frame 3 on the resin sand storage tank 1. An array of stirring paddles 304 is installed above the rotating shaft 302 on the motor 301. An auger 305 is installed below the rotating shaft 305 and is located inside the top column 2. The motor 301 drives and controls the rotating shaft 302 to rotate. The stirring paddles 304 disperse the resin sand stored in the resin sand storage tank 1. The auger 305 can process the resin sand in an orderly manner.
[0023] A casting and conveying assembly is installed on the upper part of the outer wall of the top column 2. The casting and conveying assembly includes a mounting ring 4. Mounting holes 401 are opened on both sides of the surface of the mounting ring 4. A guide post 402 is installed inside the mounting hole 401. The outer wall of the guide post 402 is slidably connected to the inner wall of the mounting hole 401. The top end of the guide post 402 is fixedly connected to the bottom of the fixing ring 101. A nut 403 is threadedly connected to the lower part of the outer wall of the guide post 402. A spring 404 is installed on the upper part of the outer wall of the guide post 402. A vibration unit 405 is installed on the end face of the outer wall of the mounting ring 4. The mounting ring 4 on the top column 2 is slidably connected to the guide post 401 on the fixing ring 101 through the mounting hole 401. At the outer wall of column 402, nut 403 is installed below the outer wall of guide column 402 by threaded connection. Spring 404 is installed on the outer wall of guide column 402. The spring 404 has a certain elastic vibration effect. When the resin sand in resin sand storage tank 1 needs to be poured into the top column, it is only necessary to use motor 301 to drive and control the auger 305 on the rotating shaft 302 to orderly transport the resin sand into hose 202. During this period, the vibration unit 405 on the installation ring 4 works with spring 404 to vibrate the resin sand in the top column 2 and corrugated pipe 201, so as to minimize the occurrence of resin sand congestion and blockage or slow material discharge.
[0024] Working principle: When using this utility model, the top column 2 is installed at the bottom of the fixing ring 101 on the resin sand storage tank 1 using a corrugated pipe 201, and is made through-hole so that the resin sand stored in the resin sand storage tank 1 can fall into the corrugated pipe 201 and enter the top column 2. The pouring process is carried out by the hose 202 on the top column 2 in conjunction with the auxiliary pipe 203. At the same time, the hose 202 and the auxiliary pipe 203 extend the pouring range, and the auxiliary pipe 203 is easy to hold for pouring. The motor 301 is installed on the resin sand storage tank 1. The mounting bracket 3 is topped with an array of stirring paddles 304 mounted above the rotating shaft 302 of the motor 301, and an auger 305 positioned below it, inside the top column 2. The motor 301 drives the rotating shaft 302 to rotate, causing the stirring paddles 304 to disperse the resin sand stored in the resin sand storage tank 1. The auger 305 then feeds the resin sand in an orderly manner. The mounting ring 4 on the top column 2 is slidably connected to the outer wall of the guide post 402 on the fixed ring 101 via the mounting hole 401, and the nut is then tightened. 403 is installed below the outer wall of the guide column 402 via a threaded connection. A spring 404 is fitted on the outer wall of the guide column 402. Utilizing the elastic vibration effect of the spring 404, when the resin sand in the resin sand storage tank 1 needs to be poured using a top column method, it only needs to be combined with the auger 305 on the rotating shaft 302 driven by the motor 301 to orderly convey the resin sand into the hose 202. During this process, the vibration unit 405 on the mounting ring 4, in conjunction with the spring 404, vibrates the resin sand in the top column 2 and the corrugated pipe 201, minimizing the occurrence of resin sand congestion that could lead to blockage or slow discharge. During the resin sand discharge process, the stirring paddle 304 and the auger 305 driven by the motor 301 rotate, ensuring orderly resin sand discharge. At the same time, in conjunction with the outlet end of the resin sand storage tank 1 under vibration, it is possible to avoid resin sand sedimentation during storage that could lead to blockage or slow discharge. This effectively improves the efficiency of top column pouring of resin sand and directly enhances the performance of the top column pouring device.
