Description

Technical Field

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

[0002] Casting is a metal heat processing technology, including metal smelting, model making, pouring solidification and demolding cleaning. After the molten metal is injected into the mold cavity and waited for cooling, a casting corresponding to the mold cavity can be obtained. After subsequent treatments such as cleaning and polishing, a casting that meets the requirements can be obtained.

[0003] The quality of the mold cavity determines the accuracy of the mold. The mold needs to be cooled while waiting for solidification and demolding. In order to improve the cooling efficiency of the mold, water cooling is often used. Sudden cooling and heating can easily cause deformation of the precise structure of the mold cavity, which will affect the processing accuracy of subsequent castings. The purpose of the utility model is to solve the above problems and propose a cooling device that can achieve mold cooling without causing excessive temperature changes to cause mold cavity deformation to solve the above problems. Utility Model Content

[0004] The utility model aims to provide a casting mold cooling device to solve the problems mentioned in the background technology.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical scheme: including a chain conveyor belt, a water tank, an electric heating rod, a temperature sensor, an electric control nozzle and a fan, the chain conveyor belt is used to convey the mold, the water tank is fixedly arranged above the chain conveyor belt, the bottom of the water tank is divided into heating chambers that are not connected to each other, the water tank is connected to the heating chamber through a one-way valve, the electric heating rod and the temperature sensor are installed in different heating chambers, the electric control nozzle is installed at the bottom of the heating chamber and is connected to the heating chamber to spray out the liquid stored in the heating chamber, and the fan is installed on one side of the chain conveyor belt.

[0006] In order to optimize the above technical solution, further measures are taken as follows: along the conveying direction of the chain conveyor belt, the heating temperature of the electric heating rod gradually decreases. The purpose of this setting is to ensure that the temperature of the water mist sprayed by the electric control nozzle gradually decreases, which can avoid the large temperature difference between the water mist and the mold causing the mold to shrink. At the same time, the gradual decrease in heating temperature helps to improve the cooling effect of the water mist on the mold.

[0007] As a further improvement of the above technical solution: along the conveying direction of the chain conveyor belt, the flow rate of the electric-controlled nozzle gradually decreases. The purpose of this setting is to reduce the impact of water mist on the mold, avoid excessive liquid adhesion on the mold surface affecting the subsequent use of the mold and the cooling effect of the airflow on the mold.

[0008] As a further improvement of the technical solution: the direction of the airflow generated by the fan is perpendicular to the conveying direction of the chain conveyor belt, and its setting purpose is to improve the cooling effect of the airflow blown by the fan on the chain conveyor belt and the mold.

[0009] As an improvement to the aforementioned technical solution: the fan is located between the heating chamber and the chain conveyor belt in the vertical direction, and the airflow generated by the fan can be restricted by the heating chamber and the chain conveyor belt to concentrate the airflow, which helps to improve the cooling effect of the airflow on the mold.

[0010] From the above description of the structure of the utility model, it can be seen that compared with the prior art, the utility model has the following advantages:

[0011] The utility model provides a casting mold cooling device, which realizes step-by-step cooling of the casting mold by controlling the step-by-step changes in the water mist flow rate and the water mist temperature, and cooperates with the air flow to achieve step-by-step cooling of the casting mold, thereby avoiding deformation of the precise structure of the mold cavity caused by rapid cooling of the mold, helping to improve the production accuracy of castings, and has practical significance and promotion value.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] Example

[0018] See also Figure 1-2The utility model provides a casting mold cooling device, including a chain conveyor belt 1, a water tank 2, an electric heating rod 3, a temperature sensor 4, an electric control nozzle 5 and a fan 6. The chain conveyor belt 1 is used to convey the mold. The water tank 2 is fixedly arranged above the chain conveyor belt 1. The bottom of the water tank 2 is divided to form mutually unconnected heating chambers 201. The water tank 2 is connected to the heating chamber 201 through a one-way valve 202. The electric heating rod 3 and the temperature sensor 4 are installed in different heating chambers 201. Along the conveying direction of the chain conveyor belt 1, the heating temperature of the electric heating rod 3 gradually decreases. The electric control nozzle 5 is installed at the bottom of the heating chamber 201 and is connected to the heating chamber 201 to spray out the liquid stored in the heating chamber 201. Along the conveying direction of the chain conveyor belt 1, the flow rate of the electric control nozzle 5 gradually decreases. The fan 6 is installed on one side of the chain conveyor belt 1. In the vertical direction, the fan 6 is located between the heating chamber 201 and the chain conveyor belt 1. The airflow direction generated by the fan 6 is perpendicular to the conveying direction of the chain conveyor belt 1.

[0019] The control method of the present invention is to realize automatic control through an external controller. The chain conveyor belt 1, the electric heating rod 3, the temperature sensor 4, the electric control nozzle 5 and the fan 6 are all connected to and controlled by the external controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. In addition, the present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0020] Working principle: the high-temperature mold after demoulding is transported on the chain conveyor belt 1. During the transportation process, the electronically controlled nozzle 5 can spray water from the water tank 2 to the heating chamber 201 to dissipate the heat of the mold in the form of water mist. After the water mist contacts the mold, it will quickly vaporize and take away the heat of the mold. The fan 6 generates airflow to dissipate the water vapor formed after the water mist vaporizes, and can also use the airflow to dissipate the heat of the mold.

[0021] The electric heating rod 3 can heat the water flowing from the water tank 2 to the heating chamber 201, and cooperate with the temperature sensor 4 to gradually reduce the water temperature in the heating chamber 201 along the conveying direction of the chain conveyor belt 1. The electric heating rod 3 heats the water so that the water mist sprayed by the electric control nozzle 5 has a certain initial temperature, reducing the temperature difference between the water mist and the mold to avoid mold shrinkage. The gradual reduction of the water mist in the heating chamber 201 can ensure the cooling effect of the water mist on the mold.

[0022] The electric-controlled nozzle 5 can pump out the water mist in the heating chamber 201 to cool the mold. The spray flow rate of the electric-controlled nozzle 5 gradually decreases. Its setting purpose is to prevent excessive water mist from being unable to vaporize in time and adhering to the mold surface, affecting the cooling effect of the airflow of the fan 6 on the mold and the subsequent use of the mold.

[0023] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
