A cooling device for button castings

Abstract

This invention proposes a cooling device for button castings, comprising a cooling tank, an air supply system, a rhomboid diffuser plate, a circulation mechanism, a cooling chamber, and a first discharge port. When the high-temperature cooling material is poured in from the discharge port, it first diffuses evenly through the top of the rhomboid diffuser plate to the top of the cooling chamber, and then slides down from the top to the bottom of the cooling chamber. During this process, the cold air initially dissipates heat from the cooling material. The initially cooled cooling material is then transported back to the top of the rhomboid diffuser plate by the circulation mechanism, thereby achieving circulating cooling of the cooling material and ensuring rapid and uniform cooling. Therefore, this invention solves the problems of low efficiency and uneven cooling caused by the previous method of directly using a fan duct for cooling.

Description

Technical Field

[0001] This utility model belongs to the field of cooling equipment technology, and mainly relates to a cooling device for button castings. Background Technology

[0002] In clothing accessories and industrial parts, metal buttons are superior to plastic and resin buttons due to their high strength, wear resistance, corrosion resistance, and recyclability. Furthermore, metal buttons offer greater flexibility in manufacturing processes, such as electroplating and engraving, allowing for diverse designs to meet the needs of different scenarios. These unique performance advantages and wide applicability make metal buttons an indispensable key component in modern manufacturing, and the demand for mass production is becoming increasingly prominent as market applications expand.

[0003] In the mass production of metal buttons, casting is typically used. During the casting process, the temperature of the cast buttons is usually as high as 150-250℃, and they need to be cooled to below 50℃ before proceeding to subsequent processing steps such as polishing, electroplating, or dyeing. Therefore, the efficiency and uniformity of the cooling process directly determine the quality of subsequent button processing and the production cycle.

[0004] Existing cooling devices for button castings generally use direct airflow from a duct. This involves stacking the die-cast buttons on a support basket and then directing the airflow from the duct towards the basket for cooling. However, this method results in the cold air not being able to directly penetrate the basket, preventing the buttons inside from cooling down quickly. This leads to low efficiency and uneven cooling, which in turn affects subsequent processing steps. Therefore, there is an urgent need for a button casting cooling device that offers high cooling efficiency and uniform cooling. Utility Model Content

[0005] The purpose of this invention is to design a cooling device for button castings to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cooling tank with a discharge port at the top, an air supply system located inside the cooling tank, a rhomboid diffuser plate fixed inside the cooling tank, and a circulation mechanism for connecting the two ends of the rhomboid diffuser plate. A cooling cavity is provided between the lower part of the rhomboid diffuser plate and the inner wall of the cooling tank. Several air outlets of the air supply system are aligned with the cooling cavity. The bottom of the cooling cavity is connected to the inlet of the circulation mechanism. A first discharge port is provided at the top of the circulation mechanism. After the circulation mechanism transfers the cooling material at the bottom of the cooling cavity to the first discharge port, the cooling material will slide from the top of the rhomboid diffuser plate into the cooling cavity.

[0007] Furthermore, the air supply system includes an annular air outlet pipe fixed inside the cooling tank, the annular air outlet pipe having a plurality of air outlets distributed circumferentially, and the annular air outlet pipe being located at the inner top or inner bottom of the cooling tank;

[0008] When the annular vent pipe is located at the inner top of the cooling tank, the vent is aligned with the feed end of the cooling chamber;

[0009] When the annular air outlet is located at the bottom of the cooling tank, the air outlet is aligned with the discharge end of the cooling chamber.

[0010] Furthermore, the cooling tank is also equipped with a feeding hopper inside, which is connected to the rhomboid diffuser plate through a vertical pipe, and the vertical pipe is provided with a plurality of first discharge ports.

[0011] Furthermore, the circulation mechanism includes a screw feeding assembly, the lower part of which is provided with several feed inlets, the top of which is connected to the vertical pipe, and the bottom of which is provided with a second discharge outlet.

[0012] Furthermore, the spiral feeding assembly includes a support cylinder connecting both ends of the rhomboid diffuser plate and an auger blade disposed inside the support cylinder. The upper part of the support cylinder is connected to an air extraction pipe, and the auger blade between the air extraction pipe and the feed inlet is provided with several air vents.

[0013] Furthermore, the support cylinder is connected to at least two of the air extraction pipes, and several of the air extraction pipes are located at the same height.

[0015] Furthermore, the distance from the suction pipe to the first discharge port is not less than the length of one pitch of the auger blade, and the distance from the feed port to the second discharge port is not less than the length of 1.5 times the pitch of the auger blade.

[0016] Furthermore, the bottom end of the support cylinder is provided with an opening and closing door.

[0017] Furthermore, the interior of the cooling chamber is also provided with a guide plate, which is inverted V-shaped, and the bottom end of the guide plate is connected to the end of the feed inlet.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows: When the high-temperature cooling material is poured in from the discharge port, it first diffuses evenly to the top of the cooling chamber through the top of the diamond-shaped diffuser plate, and then slides down from the top of the cooling chamber to the bottom. During this process, the cold air initially dissipates heat from the cooling material, and the initially dissipated cooling material is then transported back to the top of the diamond-shaped diffuser plate by the circulation mechanism, thereby realizing the circulation and cooling of the cooling material, ensuring that the cooling material cools down quickly and evenly. Therefore, this utility model solves the problems of low efficiency and uneven cooling caused by the previous method of directly using a fan duct for cooling. Attached Figure Description

[0023] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0024] Example: Please refer to Figures 1-2A cooling device for button castings includes a cooling tank 1 with a pouring port 3 at the top, an air supply system 8 inside the cooling tank 1, a rhomboid diffuser plate 13 fixed inside the cooling tank 1, and a circulation mechanism 2 for connecting the two ends of the rhomboid diffuser plate 13. A cooling cavity 12 is provided between the lower part of the rhomboid diffuser plate 13 and the inner wall of the cooling tank 1. The lower part of the cooling tank 1 is inverted conical, and the taper is the same as the lower taper of the rhomboid diffuser plate 13. The cooling tank 1 is supported and fixed by a support frame 4 to ensure stability during cooling. The air supply system 8 can be a common blower system. The difference is that several air outlets of the air supply system 8 are aligned with the cooling cavity 12. Since the cross-section of the cooling cavity 12 is annular in this embodiment, several air outlets are circumferentially distributed at the ends of the cooling cavity 12.

[0025] The bottom of the cooling chamber 12 is connected to the inlet 15 of the circulation mechanism 2. The top of the circulation mechanism 2 is provided with a first outlet 11. After the circulation mechanism 2 transfers the cooling material at the bottom of the cooling chamber 12 to the first outlet 11, the cooling material will slide from the top of the diamond diffuser plate 13 to the cooling chamber 12. Therefore, when the high-temperature cooling material (metal button) is poured in from the pouring port 3, it first diffuses evenly through the top of the diamond diffuser plate 13 to the top of the cooling chamber 12 (i.e., the inlet end), and then slides from the top of the cooling chamber 12 to the bottom (i.e., the outlet end). During this process, the cold air dissipates heat from the diffused cooling material. The cooling material that slides to the bottom is transported back to the first outlet 11 by the circulation mechanism 2 and slides from the top of the diamond diffuser plate 13 to the inlet end of the cooling chamber 12, thereby realizing the circulation cooling of the cooling material and ensuring that the cooling material cools down quickly and evenly. Therefore, this utility model solves the problems of low efficiency and uneven cooling caused by the previous method of directly using a fan duct for cooling.

[0026] In this embodiment, the cooling tank 1 is further provided with a feeding hopper 10. The feeding hopper 10 is connected to the rhomboid diffuser plate 13 through a vertical pipe 20. The vertical pipe 20 is provided with several first discharge ports 11, so that the cooling material can be evenly diffused from the top of the rhomboid diffuser plate 13 regardless of the angle at which the operator pours the material, so that the cooling material can dissipate heat evenly and also ensure the circulation and cooling of the cooling material. In addition, the air supply system 8 includes an annular air outlet pipe 9 fixed inside the cooling tank 1. The annular air outlet pipe 9 has several air outlets distributed circumferentially. In other embodiments, the annular air outlet pipe 9 can be located at the bottom of the cooling tank 1. In this case, the air outlets are aligned with the discharge end of the cooling chamber 12. In this case, the feeding hopper 10 adopts the form of a mesh plate to facilitate complete... After heat exchange, the cold air flows out from the outlet end of the cooling chamber 12 to the inlet end. While dissipating heat from the cooling material, it also creates a certain damping on the downward sliding of the cooling material, thereby increasing the residence time of the cooling material inside the cooling chamber 12 and improving the cooling effect. The cold air flowing out from the inlet end of the cooling chamber 12 will conduct preliminary heat dissipation on the cooling material in the inlet hopper 10 through the mesh, thereby initially reducing the temperature of the cooling material. After two heat exchanges, the cold air will flow out from the mesh-covered inlet hopper 10. Therefore, this structure not only increases the cooling time of the cooling material in the cooling chamber 12 but also conducts preliminary heat dissipation on the cooling material in the inlet hopper 10, greatly improving the overall cooling effect of the device.

[0027] In this embodiment, the circulation mechanism 2 includes a spiral feeding assembly. The lower part of the spiral feeding assembly has four circumferentially distributed inlets 15. The top of the spiral feeding assembly is connected to the vertical pipe 20, and the bottom of the spiral feeding assembly has a second outlet with an opening / closing door 7. The spiral feeding assembly is configured to convey cooling material upwards when rotating forward and downwards when rotating in reverse. Therefore, when the spiral feeding assembly rotates forward, it achieves circulating cooling of the cooling material, and when it rotates in reverse, it achieves discharging of the cooling material. Thus, a receiving frame 6 is placed at the bottom of the spiral feeding assembly for easy material collection. The spiral feeding assembly includes a support cylinder 14 connecting both ends of the rhomboid diffuser plate 13 and an auger blade 19 located inside the support cylinder 14. The auger blade 19 is driven by a motor mounted on the cooling tank 1. In other embodiments, the motor can be located above the cooling tank 1 with a safe distance between it to prevent the heat from the cooling material from affecting the normal operation of the motor. The upper part of the support cylinder 14 is connected to an exhaust pipe 5, which is connected to a blower to achieve cooling... The cooling air inside the tank 1 is drawn out; and the auger blades 19 between the exhaust pipe 5 and the feed inlet 15 are provided with several vent holes 17; therefore, in this embodiment, the annular exhaust pipe 9 is located at the inner top of the cooling tank 1, and the exhaust port is aligned with the feed end of the cooling chamber 12. The cold air flows from the feed end to the discharge end of the cooling chamber 12 and flows into the exhaust pipe 5 through the vent holes 17, thereby achieving the cooling of the cooling material during the circulating feeding process while reducing the temperature of the screw feeding assembly, thereby reducing the overall temperature of the device, which is conducive to improving the cooling efficiency and quality of the cooling material; therefore, this device continuously cools the cooling material inside the cooling chamber 12 and the support cylinder 14, which greatly improves the cooling effect of the entire device; in addition, in order to prevent the cooling material from being scratched during the transportation of the auger blades 19, the materials of the auger blades 19 and the support cylinder 14 in this embodiment can be made of hard fluororubber, which has a high temperature resistance range of 200-300℃, thereby ensuring that the metal buttons will not be scratched while normal transportation is carried out.

[0028] In this embodiment, a filter element 18 is fixedly connected to one end of the exhaust pipe 5 near the support cylinder 14 to prevent coolant from entering the exhaust pipe 5 and causing blockage. The filter element 18 can be in the form of a filter screen or filter block, which will not be described in detail here. The support cylinder 14 is connected to three exhaust pipes 5, which are located at the same height to ensure sufficient airflow within the support cylinder 14. Furthermore, the distance from the exhaust pipe 5 to the first discharge port 11 is not less than one pitch of the auger blade 19 to prevent the exhaust pipe 5 from drawing gas from the top of the rhomboid diffuser plate 13, thereby affecting... The flow of cold air inside the support cylinder 14 is affected; and the distance from the feed inlet 15 to the second discharge outlet is not less than 1.5 times the pitch of the auger blade 19, to prevent excessive cooling material from falling directly out of the second discharge outlet when the opening and closing door 7 is open, while ensuring the stable flow of cold air inside the support cylinder 14; in addition, the cooling chamber 12 is also provided with a guide plate 16, which is inverted V-shaped, and the bottom end of the guide plate 16 is connected to the end of the feed inlet 15, so as to guide the cooling material inside the cooling chamber 12 to the feed inlet 15 and prevent the cooling material from accumulating at the bottom of the cooling tank 1.

[0029] Working principle: When cooling of metal buttons is required, the cooling system and circulation mechanism 2 are activated first. Then, the hot metal buttons are poured in through the discharge port 3, and then evenly diffused through several first discharge ports 11 and the top of the diamond-shaped diffuser plate 13 to the inlet end of the cooling chamber 12. They then slide down from the top of the cooling chamber 12 to the outlet end. During this process, cold air is blown out from the air outlet, dissipating heat from the diffused metal buttons. The metal buttons that slide down to the outlet end enter the support cylinder 14 through the inlet 15 and are then placed under the influence of the auger blades 19. Under the action of the airflow, the metal button moves upward. During the movement, the cold air flows inside the support cylinder 14 along with the metal button to continuously dissipate heat from the metal button. The cold air eventually flows out from the exhaust pipe. The metal button is transported to the first discharge port 11 by the auger blades 19 and slides down from the top of the diamond diffuser plate 13 to the feed end of the cooling chamber 12, thereby realizing the circulation and cooling of the cooling material. This ensures that the cooling material cools down quickly and evenly. Therefore, this invention solves the problems of low efficiency and uneven cooling caused by the previous method of directly using the air duct for cooling.
