Technical Field
[0001] The utility model relates to the field of industrial production equipment, in particular to a dewaxing kettle with a dewaxing chamber and a steam pipe for rapid water removal. Background Art
[0002] Dewaxing kettle is a kind of equipment used in investment casting, which is mainly used to remove wax from wax patterns for subsequent casting process. Its working principle is to use high temperature to melt the wax pattern, and then discharge the wax liquid through a specific device to obtain a wax-free casting model. Steam dewaxing kettle is a type of dewaxing kettle, which uses steam as a heat source to heat the wax pattern to melt it. Steam dewaxing kettle has the advantages of uniform heating, precise temperature control, and easy operation, so it has been widely used in investment casting.
[0003] After the wax mold enters the dewaxing kettle, the steam pipe is opened to rapidly increase the temperature inside the dewaxing kettle, causing the wax mold to begin to melt and fully reveal the casting in the wax mold, thereby completing the acquisition of the wax mold casting. Because steam is used to heat the surface of the wax mold evenly, and then the wax mold is evenly heated and melted, there will be no cracking of the wax mold due to uneven heating, which will cause the casting inside the wax mold to bend or crack. However, due to the steam demolding method, the water molecules in the steam will be adsorbed on the surface of the casting, causing the surface of the casting to be wetted. After being taken out of the dewaxing kettle, it needs to be treated before subsequent processing can be carried out.
[0004] The existing dehydration treatment of castings generally involves taking the castings out of the dewaxing kettle, placing them separately, and waiting for natural drying. In order to speed up the dehydration process, some manufacturers use fans to assist.
[0005] However, because the reactor is a high-pressure and high-temperature environment, and because the steam is humid, after the casting is taken out, the water on its surface evaporates quickly and takes away the heat. At this time, the core temperature of the casting is high and the external temperature is low, which may cause the casting to become brittle and lead to problems with the quality of the casting being unqualified. Utility Model Content
[0006] Based on this, the purpose of the utility model is to provide a dewaxing kettle with a dewaxing chamber and a steam pipe for rapid water removal, so as to solve the technical problem that because the reactor is a high-pressure and high-temperature environment and because the steam is moist, after the casting is taken out, the water on its surface evaporates quickly to take away the heat. At this time, the core temperature of the casting is high and the external temperature is low, which may cause the casting to become brittle and lead to the problem of unqualified casting quality.
[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a dewaxing chamber with a steam pipe for rapid water removal dewaxing kettle, comprising a dewaxing chamber, a cooling chamber is arranged on one side of the dewaxing chamber, a limiting plate is arranged at the connection between the dewaxing chamber and the cooling chamber, and a limiting plate is provided on the cooling chamber to cooperate with the limiting plate, a plurality of dewaxing molds are arranged on one side of the dewaxing chamber, a plurality of mold fixing top plates are arranged on the side of the limiting plate close to the dewaxing mold, a plurality of mold limiting rods are arranged at the bottom of the mold fixing top plate, a mold fixing bottom plate is arranged at the other end of the mold limiting rod in the dewaxing mold, an evaporation tank is arranged on the side of the dewaxing chamber away from the dewaxing mold, a transmission rod is rotated in the evaporation tank, the transmission rod is arranged through the dewaxing mold and the dewaxing chamber, the transmission rod is connected to a motor at one end outside the dewaxing chamber, and a baffle is provided on the cooling chamber to cooperate with the motor.
[0008] By adopting the above technical solution, the wax model is fixed by the set dewaxing mold, and then separated from the dewaxing chamber by moving the limiting plate, and then the wax model is placed and taken out.
[0009] The utility model is further configured that a first heating component is arranged in the evaporation tank, a steam conveying ring is arranged in the evaporation tank, a groove is arranged in the dewaxing mold to match the steam conveying ring, and an opening is arranged in the inner wall of the dewaxing mold.
[0010] By adopting the above technical solution, the first heating component is provided to evaporate the water in the evaporation tank, and the wax mold is melted by steam, thereby achieving demoulding.
[0011] The utility model is further configured that the inner wall of the cooling chamber is provided with a second heating component.
[0012] By adopting the above technical solution, the cooling chamber is heated by the second heating component to ensure that after the device is separated from the high-pressure environment of the demoulding chamber, the device will not become brittle or even break due to a sudden drop in temperature.
[0013] The utility model is further configured that a cover plate is rotatably arranged on the outer wall of the cooling chamber, a fan is arranged on the cover plate, and the fan is connected to the inside of the cooling chamber.
[0014] By adopting the above technical solution, the cover plate is added into the device and placed between a plurality of limit rods, and the dewaxed device is taken out at the same time.
[0015] The utility model is further configured that a liquid discharge port is arranged at the bottom of the opening in the dewaxing mold, and a discharge port is arranged outside the dewaxing chamber.
[0016] By adopting the above technical solution, the melted wax is discharged through the provided discharge port.
[0017] In summary, the utility model mainly has the following beneficial effects:
[0018] The utility model drives the transmission rod to rotate through a motor, thereby driving the limit plate to move up and down, and at the same time drives the mold fixing device connected to the limit plate to move up and down synchronously, thereby controlling the movement of the mold in the dewaxing chamber and the cooling chamber, and evaporates the water in the evaporation tank through the first heating component, so that the water is transported to the dewaxing chamber through the steam delivery ring to realize the evaporation and melting of the wax mold. After dewaxing is completed, the mold fixing device moves to the cooling chamber, and the mold is cooled by blowing air through the set fan. At the same time, the second heating component heats the cooling chamber to a certain extent, so that the temperature in the cooling chamber is stable, ensuring that the mold will not become brittle due to sudden excessive cooling.
