Description

Technical Field

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

[0002] In a casting workshop, baking and preheating of low-pressure casting and gravity casting metal molds is a very important step before production. The casting metal mold includes an upper mold and a lower mold, both of which need to be baked and preheated. The purpose is to meet the requirements of the casting process, ensure the smooth progress of the casting process, guarantee the quality and surface finish of the casting, and improve production efficiency and product quality.

[0003] In the related art, currently, the baking and preheating of the casting metal mold by the baking device is through the negative pressure suction method of compressed air. The kerosene torch is used to ignite and bake the upper and lower molds of the casting metal mold respectively. The fuel combustion of this method is uneven, resulting in low combustion efficiency and long baking time. And during the baking period, kerosene needs to be added to the baking device to maintain the baking, and there is an overflow or leakage phenomenon during the kerosene addition process, thus leading to the risk of triggering safety accidents. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a baking device for casting metal mold to solve at least one aspect of the problems and defects mentioned in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A baking device for casting metal mold, comprising:

[0007] A baking device and an ignition device. A fuel storage tank is arranged in the baking device, and an oil delivery port is arranged at the top of the fuel storage tank;

[0008] A pressure oil pipe is arranged on one side of the oil delivery port;

[0009] A main compressed air pipe, one end of which is communicated with a pressure tank, and the other end of which is communicated with the pressure oil pipe;

[0010] A compressed air branch pipe is arranged on the main compressed air pipe, and the compressed air branch pipe is communicated with the fuel storage tank;

[0011] An atomizing nozzle is arranged at the communication place of the main compressed air pipe and the pressure oil pipe, and one end of the atomizing nozzle extends into the ignition device.

[0012] The baking device for casting metal mold according to this solution has at least the following technical effects:

[0013] This foundry metal mold baking device uses a pressure tank pressurization method, replacing the original compressed air negative pressure suction method. It atomizes and sprays kerosene using compressed air through an atomizing nozzle, effectively spraying the oil evenly, making the oil burn more fully, improving the combustion efficiency, enabling it to bake the upper and lower molds of the foundry metal mold simultaneously, greatly shortening the baking time, and being able to continuously bake multiple foundry metal molds, achieving preheating of the foundry metal mold before production, eliminating the need to configure multiple baking devices, saving production costs, and improving work efficiency.

[0014] As a further solution of the present utility model: A fuel filling valve is provided at the top of the fuel inlet.

[0015] Since a fuel filling valve is provided at the top of the fuel inlet, adding fuel to the storage tank is more convenient and accurate, preventing fuel overflow during fuel addition, thus avoiding waste of fuel and also avoiding safety accidents caused by fuel overflow, improving the operation convenience and safety.

[0016] As a further solution of the present utility model: An atomizing pressure regulating valve is provided on the main compressed air pipe.

[0017] By providing an atomizing pressure regulating valve on the main compressed air pipe, the pressure in the main compressed air pipe can be precisely adjusted to ensure stable gas pressure and flow rate when atomization treatment is required, effectively enhancing the atomization effect of the oil, improving the combustion efficiency; and it can effectively control energy consumption, avoid unnecessary energy waste, and save operation costs.

[0018] As a further solution of the present utility model: An oil pressure valve is provided on the branch compressed air pipe.

[0019] Since an oil pressure valve is provided on the branch compressed air pipe, by adjusting the oil pressure valve, the oil in the storage tank can be effectively pressurized to ensure the smooth ejection of the oil, avoiding the influence on the atomization effect and thus the combustion efficiency due to too low oil ejection pressure, effectively improving the stability and reliability of this baking device.

[0020] As a further solution of the present utility model: An oil pressure valve is provided on the oil pressure pipe.

[0021] By providing an oil pressure valve on the oil pressure pipe, the size of the oil output can be precisely controlled, preventing the oil flow rate from being too high or too low, ensuring the stable operation of the baking device, and improving the stability and safety of this baking device.

[0022] As a further solution of the present utility model: The oil storage capacity of the storage tank is 45L - 55L.

[0023] Since the oil storage capacity of the oil storage tank is 45L - 55L, the oil storage capacity of the baking device is enhanced. Under the full - oil state, the mold can be baked twice, avoiding the need to add oil during the baking process, reducing the complexity of operation, avoiding safety accidents caused by adding oil during the baking process, and improving the reliability of the baking device.

[0040] Further, an oil pressure boosting valve 109 is provided on the branch compressed air pipe 105.

[0041] Specifically, since the oil pressure boosting valve 109 is provided on the branch compressed air pipe 105, by adjusting the oil pressure boosting valve 109, the fuel in the storage tank 101 can be effectively pressurized to ensure smooth fuel ejection, avoiding the influence on the atomization effect and thus the combustion efficiency due to too small fuel ejection pressure, and effectively improving the stability and reliability of the roaster 10.

[0042] Further, an oil pressure valve 110 is provided on the pressure oil pipe 103.
