Description

Technical Field

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

[0002] Casting is a hot working process. The principle is to pour liquid metal into a casting cavity that is adapted to the shape of the part, and then wait for it to cool and solidify to obtain a part or blank.

[0003] During casting, the cast material is mostly metal heated to a liquid state, and its temperature is very high. After casting, it needs to wait for it to cool and set before the next process can be carried out. After the existing castings are cast, they are usually placed directly on a sandbox for air cooling. The cooling speed is slow, so the waiting time is usually very long, which affects the production efficiency. In order to speed up the cooling speed, some jet tools (such as spray guns) are sometimes equipped to blow air at the high-temperature castings through the spray guns to improve the heat dissipation effect, so as to achieve the purpose of helping the castings to cool down quickly. However, this method requires manual operation to control the spray gun to exhaust and stop the air, which is time-consuming and laborious to operate. In addition, when encountering a situation where many castings need to be cooled, they can only be cooled one by one, which is slow and inefficient. Utility Model Content

[0004] In view of this, in order to solve the problems existing in the above-mentioned prior art, the utility model provides a casting cooling auxiliary device with fast heat dissipation speed, good heat dissipation effect and high efficiency.

[0005] A casting cooling auxiliary device comprises a base, on which a gas delivery component, a control valve and a plurality of guide pillars are arranged, the gas delivery component comprises a plurality of gas outlets arranged at intervals, the control valve is arranged on one side of the gas delivery component, a contact switch is arranged on the top of the control valve, a movable plate is arranged above the gas delivery component, a plurality of ventilation slots are opened on the movable plate, the movable plate is slidably mounted on the plurality of guide pillars, an elastic member is sleeved on the guide pillars, and the two ends of the elastic member are respectively against the base and the movable plate.

[0006] In the above technical solution, the gas delivery component is externally connected to a gas supply device for providing gas to the gas delivery component. An air inlet valve is provided at the connection between the gas delivery component and the gas supply device. The control valve can control the opening and closing of the air inlet valve. When the contact switch on the top of the control valve is pressed, the air inlet valve opens, the gas delivery component operates, and the gas is blown out through the air outlet. After the contact switch is released, the air inlet valve closes, and the gas delivery component stops operating. The movable plate is located above the gas delivery component, and a plurality of ventilation slots arranged at intervals are provided on the movable plate for the gas blown out of the air outlet to pass through. The movable plate is provided with holes that match the guide posts, so that the movable plate can be installed on the guide posts, and the guide posts can be vertically connected. The movable plate is arranged perpendicular to the top surface of the base, and can slide up and down along the direction of the guide column. An elastic member is sleeved on the guide column. When the high-temperature casting is placed on the top of the movable plate, the movable plate moves downward under the action of gravity, causing the elastic member to compress until the movable plate contacts the contact switch on the top of the control valve, so that the gas transmission component starts to run, and air is blown to the casting above through the air outlet to cool the casting. When the casting is cooled and taken away, the movable plate moves upward under the elastic force of the elastic member to reset. At this time, the contact switch on the top of the control valve is released, the air supply device stops supplying air, and the gas transmission component automatically stops running. No manual operation and control are required, thereby improving efficiency.

[0007] Furthermore, as a preferred technical solution, the gas delivery assembly includes at least one group of gas delivery mechanisms, each group of the gas delivery mechanisms includes a plurality of gas delivery pipes parallel to each other, and the gas outlets are distributed at intervals on the gas delivery pipes.

[0013] Furthermore, as a preferred technical solution, the ventilation slots are in the same direction as the air pipes, and each air pipe is correspondingly provided with one ventilation slot.

[0014] In the above technical solution, each gas pipe is provided with a corresponding ventilation slot, and the ventilation slot is located directly above the gas pipe to avoid blocking the gas outlet and ensure the heat dissipation effect.

[0015] Furthermore, as a preferred technical solution, a top block corresponding to the control valve is provided at the bottom of the movable plate.

[0031] The following will further describe the casting cooling auxiliary device of the utility model in detail in combination with specific embodiments and drawings. The drawings are only used for exemplary descriptions, and only show schematic diagrams, not actual drawings, and cannot be understood as limitations on this patent; in order to better illustrate the embodiments of the utility model, some parts of the drawings may be omitted, enlarged or reduced, and do not represent the size of the actual product; for those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted. Example 1

[0032] Please refer to Figures 1 to 4 In a preferred embodiment, a casting cooling auxiliary device is provided, which includes a base, on which a gas delivery component, a control valve and a plurality of guide pillars are provided, the gas delivery component includes a plurality of gas outlets arranged at intervals, the control valve is arranged on one side of the gas delivery component, a contact switch is arranged on the top of the control valve, a movable plate is arranged above the gas delivery component, a plurality of ventilation slots are opened on the movable plate, the movable plate is slidably mounted on the plurality of guide pillars, an elastic member is sleeved on the guide pillars, and the two ends of the elastic member are respectively against the base and the movable plate.

[0033] In this embodiment, the gas delivery component is externally connected to a gas supply device (not shown in the figure) for outputting gas, and an air intake valve (not shown in the figure) is provided at the connection between the gas delivery component and the gas supply device, and the control valve is electrically connected to the air intake valve to control the opening and closing of the air intake valve. Specifically, a contact switch is provided on the top of the control valve. When the contact switch on the top of the control valve is pressed, the air intake valve opens, the gas supply device supplies gas, the gas delivery component operates, and the gas is blown out through the gas outlet. When the contact switch on the top of the control valve is released, the air intake valve closes, the gas supply stops, and the gas delivery component stops operating. The movable plate is located above the gas delivery component, and a plurality of ventilation slots arranged at intervals are provided on it. The ventilation slots correspond to the positions of the gas outlet so that the gas blown out of the gas outlet can pass through. A hole matching the guide column is opened at the corner position so that the movable plate can be installed on the guide column. The guide column is arranged perpendicular to the top surface of the base. The movable plate can slide up and down along the direction of the guide column. An elastic member is sleeved on the guide column. Preferably, the elastic member is a spring. When the high-temperature casting is placed on the top of the movable plate, the movable plate moves downward under the action of gravity, causing the elastic member to compress until the movable plate contacts the contact switch on the top of the control valve, so that the gas transmission component starts to run, and air is blown to the casting above through the air outlet to cool the casting. When the casting is cooled and taken away, the movable plate moves upward under the elastic force of the elastic member to reset. At this time, the contact switch on the top of the control valve is released, the air supply device stops supplying air, and the gas transmission component automatically stops running. No manual operation and control are required, thereby improving efficiency.

[0034] Preferably, the control valve is a solenoid valve to improve control accuracy and response speed.

[0035] Please refer to Figure 1 and Figure 2 In this embodiment, the gas delivery assembly includes a group of gas delivery mechanisms, which include multiple gas delivery pipes. The gas delivery pipes are arranged at intervals and kept parallel to each other. Multiple air outlets are arranged at intervals on each gas delivery pipe. In conjunction with the multiple ventilation slots on the movable plate, air blowing can be performed to dissipate heat for multiple castings placed at various positions of the movable plate, thereby accelerating the cooling rate, and dissipating heat for multiple castings at the same time, effectively improving the heat dissipation efficiency.

[0036] Please refer to Figures 1 to 3 In this embodiment, the gas delivery mechanism includes an air inlet pipe, which is perpendicular to the air delivery pipe. One end of all the air delivery pipes is connected to the side of the air delivery pipe. The air inlet pipe is used to transport the gas delivered by the air supply device to each air delivery pipe; an air inlet is provided on the other side of the air inlet pipe, which is connected to an external air supply device, and the gas provided by the air supply device enters the air inlet pipe through the air inlet.

[0037] Please refer to Figure 1 and Figure 4 In this embodiment, the ventilation groove is strip-shaped and has the same direction as the air pipe. Each air pipe is provided with a corresponding ventilation groove, and the ventilation groove is located directly above the air pipe to avoid blocking the air outlet on the air pipe, thereby ensuring the heat dissipation effect of the casting above the movable plate.

[0038] Please refer to Figure 1 and Figure 3 In this embodiment, a protruding top block is provided at a position on the bottom of the movable plate corresponding to the control valve. The top block is used to contact the contact switch on the top of the control valve when the movable plate is pressed down. The top block is made of soft material, which can provide a certain buffering effect to avoid excessive impact force when contacting the control valve, resulting in damage to the control valve.

[0039] It should be noted that the top block in this embodiment is made of rubber, which has a certain elasticity and can provide a certain buffering effect to prevent the top block from hitting the control valve and causing damage to it when the movable plate is pressed down. In addition to rubber, other softer elastic materials can also be used.

[0040] Please refer to Figures 1 to 3 In this embodiment, a limit column is provided on one side of the guide column on the substrate, and the limit column is arranged perpendicular to the top surface of the substrate, wherein the height of the limit column is lower than the guide column, and is used to limit and support the movable plate when the movable plate moves downward to avoid excessive pressure on the control valve.

[0041] It should be noted that when the movable plate moves down to contact the limit column, the top block just presses the contact switch on the top of the control valve. Therefore, the supporting force of the movable plate is mainly provided by the limit column, which can effectively prevent the control valve from being subjected to greater pressure.

[0042] Please refer to Figures 1 to 3In this embodiment, a plurality of protruding support blocks are provided at the edge of the bottom of the base, so that the bottom of the base is suspended, which is convenient for carrying and transferring the device. Example 2

[0044] Please continue to refer to Figure 5 In this embodiment, two groups of gas delivery mechanisms are vertically arranged so that the gas delivery pipe forms a grid-like structure. Correspondingly, the ventilation slots on the movable plate are also arranged according to the positions of the gas delivery pipes, that is, the ventilation slots also form a grid-like structure corresponding to the gas delivery pipes. By setting two groups of gas delivery mechanisms, the air outlets are more numerous and denser, which can effectively increase the overall air volume, increase the cooling speed of the casting, and make the overall air outlet more dense and uniform, which can meet the heat dissipation needs of the casting at any position on the movable plate and accelerate the cooling speed.

[0045] It should be noted that the two groups of gas delivery mechanisms in this embodiment are arranged up and down, that is, one group of gas delivery mechanisms is located above the other group of gas delivery mechanisms. In addition to the above-mentioned arrangement, the gas delivery pipes in the two groups of gas delivery mechanisms can also be connected, that is, the two groups of gas delivery mechanisms are arranged in the same plane, and the gas delivery pipes in the two groups of gas delivery mechanisms are interpenetrating. The specific arrangement can be made according to actual needs.

[0046] Specifically, Figure 5 As shown, in this embodiment, the gas delivery mechanism located at the bottom includes 5 gas delivery pipes, and the gas delivery mechanism located at the top includes 6 gas delivery pipes, which are arranged at the interval positions of the gas outlets of the lower gas delivery pipes.
