Description

TECHNICAL FIELD

[0001] The present application relates to the field of aluminum product processing, in particular, relates to an aluminum product casting device with surface oxidation resistance treatment function. BACKGROUND

[0002] Aluminum products are life supplies and industrial supplies processed by using aluminum alloy as the main raw material. Aluminum alloy is a general term for alloys based on aluminum, the main alloying elements are copper, silicon, magnesium, zinc, manganese, and the secondary alloying elements are nickel, iron, titanium, chromium, lithium, etc. Aluminum alloy has low density, but high strength, which is close to or exceeds that of high-quality steel. It has good plasticity and can be processed into various profiles. It has excellent electrical conductivity, thermal conductivity and corrosion resistance, and is widely used in industry. Aluminum products are often produced by pouring method during production. During the pouring production process, the molten aluminum alloy liquid is poured into the mold, and after cooling, the mold is opened to take out the aluminum product. For example, the aluminum product production casting device disclosed in Chinese patent application No. CN202421608128.1 includes a working frame, a support plate is fixedly installed at the lower end inside the working frame, a fixed block is fixedly installed on the inner wall of one side of the working frame, a fixed mold is fixedly installed between the other side of the fixed block, a gas cylinder is fixedly installed on the outer wall of the other side of the working frame, and a movable mold is fixedly arranged at the end of the gas cylinder. In the utility model, when the gas cylinder moves to push the movable mold to move along the two limiting sliding grooves of the support plate until the movable mold is combined with the fixed mold, then the gas injection pipe fills the inert gas into the casting cavity, the drainage fan cooperates with the flow guide pipe to guide the air squeezed out of the casting cavity until the casting cavity is filled with inert gas, thereby avoiding the aluminum liquid from being oxidized by air when introduced into the casting cavity to produce aluminum slag and holes. When the aluminum liquid is introduced into the casting cavity from the pouring opening, the drainage fan and the flow guide pipe continue to cooperate to guide the inert gas squeezed out of the aluminum liquid into the recovery pipe.

[0003] However, the above scheme still has certain defects. First, the aluminum liquid inside the mold after the mold is combined cools and solidifies to form a casting. Since there may be friction between the aluminum product and the mold, and the casting may be tightly attached to the inner wall of the mold, it is not convenient to take out the casting. Second, the natural cooling method leads to slow casting forming efficiency, thereby reducing the practicality. UTILITY MODEL CONTENTS

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0027] Please refer to Figures 1-4 The present application provides an aluminum product casting device with surface oxidation treatment function, which comprises an ejection assembly 100 and a moving assembly 200.

[0028] Please refer to Figures 1-3 The ejection assembly 100 comprises a frame plate 110, a fixed mold 120, an electric push rod 140, a drainage fan 150, and a gas injection pipe 160. The fixed mold 120 is fixedly connected with the frame plate 110. The fixed mold 120 is internally provided with a first cooling cavity 130. The electric push rod 140 is arranged at one end of the frame plate 110. The output end of the electric push rod 140 penetrates through and is connected to one side of the fixed mold 120. The drainage fan 150 is arranged at one end of the frame plate 110. The drainage fan 150 is in communication with the fixed mold 120. The gas injection pipe 160 penetrates through and is connected to one side of the frame plate 110 and the fixed mold 120. One side of the frame plate 110 is provided with a support plate 111. One side of the support plate 111 is correspondingly provided with a sliding groove 112. Two sliding rods 113 are arranged at one side of the frame plate 110. The arrangement of the support plate 111 can play a supporting role. The arrangement of the sliding rod 113 can play a connecting role.

[0029] In some specific implementations, a pouring port 121 is provided on one side of the fixed mold 120, a first liquid inlet pipe 122 is provided on one side of the fixed mold 120, and a first liquid outlet pipe 123 is provided on one side of the fixed mold 120. The pouring port 121 facilitates the introduction of molten aluminum into the casting cavity, the first liquid inlet pipe 122 facilitates the injection of coolant into the fixed mold 120, and the first liquid outlet pipe 123 facilitates the discharge of coolant. A first push plate 141 is provided at the output end of the electric push rod 140. The push plate 141 is slidably connected to the fixed mold 120. The first push plate 141 increases the contact area with the casting to prevent surface damage when the casting is ejected. A guide pipe 151 is provided on one side of the flow fan 150. The guide pipe 151 is connected through to one side of the fixed mold 120. A recovery pipe 152 is provided on one side of the flow fan 150. The guide pipe 151 can serve as a connection. At the same time, a one-way valve can be provided inside the guide pipe 151 to effectively prevent the backflow of air and inert gas.

[0030] In some specific implementation schemes, such as the casting apparatus for producing aluminum products described in Chinese patent application number CN202421608128.1, the specification clearly states that an insert plate is provided at one end of the guide pipe 151 and the gas injection pipe 160, and is embedded and installed in the fixed mold 120. The insert plate has an I-shaped groove inside, and a plug is slidably installed inside the I-shaped groove. When inert gas is introduced through the gas injection pipe 160 and when the guide pipe 151 cooperates with the flow fan 150 to induce negative pressure, the plug inside the insert plate is blocked by the inert gas. The airflow lifts the plug inside the insert plate, causing it to sag due to the weight of the counterweight, facilitating air exhaust. Conversely, when the air injection pipe 160 stops introducing inert gas and the drainage fan 150 stops working, the plug inside the insert plate sags due to the weight of the counterweight, thus sealing the I-shaped groove. Inside the insert plate, the inert gas is squeezed out by the molten aluminum, causing the plug to be finally squeezed by the pressure inside the casting cavity and sealing the I-shaped groove. Therefore, the principle is clear to those skilled in the art and will not be explained in detail here.

[0031] Please see Figure 1 , Figure 2 and Figure 4The moving component 200 includes a cylinder 210, a moving mold 220, and ejector rods 240. The cylinder 210 is connected through to one side of the frame plate 110. The moving mold 220 is slidably connected to the frame plate 110 and fixedly connected to the cylinder 210 and the moving mold 220. A second cooling chamber 230 is provided inside the moving mold 220. Both ejector rods 240 are fixedly connected to the frame plate 110 and slidably connected to the moving mold 220. A second liquid inlet pipe 221 is provided on one side of the moving mold 220, a second liquid outlet pipe 222 is provided on one side of the moving mold 220, and a... The connecting plate 223 is slidably connected to the slide rod 113. Two slide plates 224 are provided on one side of the moving mold 220. The slide plates 224 are slidably connected to the slide groove 112. The second liquid inlet pipe 221 facilitates the injection of coolant into the moving mold 220, and the second liquid outlet pipe 222 facilitates the discharge of coolant. The slide plates 224 can serve as a connection. One end of the ejector rod 240 is provided with a second push plate 241. The second push plate 241 is slidably connected to the moving mold 220. The second push plate 241 increases the contact area with the casting and prevents surface damage when the casting is ejected.

[0032] The working principle of this aluminum product casting device with surface anti-oxidation treatment function is as follows: In use, inert gas is first filled between the fixed mold 120 and the moving mold 220 through the gas injection pipe 160. The exhaust fan 150, through the guide pipe 151, exhausts the compressed air between the fixed mold 120 and the moving mold 220 until the casting cavity is filled with inert gas. This prevents the molten aluminum from being oxidized by air when it enters the casting cavity, thus preventing the formation of aluminum slag and pinholes, achieving an anti-oxidation treatment effect. Injecting coolant into the first cooling chamber 130 and the second cooling chamber 230 can accelerate the process between the fixed mold 120 and the moving mold 220. The formation of the casting between the two molds improves the molding effect. The moving mold 220 is moved by the cylinder 210. When the casting is inside the moving mold 220, the casting can be ejected by the ejector rod 240. The second push plate 241 increases the contact area with the casting to prevent surface damage during ejection. When the casting is inside the fixed mold 120, the casting can be ejected by the electric push rod 140. The first push plate 141 increases the contact area with the casting to prevent surface damage during ejection, thus facilitating the removal of the casting and improving the casting forming efficiency, thereby improving practicality.

[0033] It should be noted that the specific models and specifications of the electric push rod 140, the diversion fan 150, and the cylinder 210 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0034] The power supply and operating principle of the electric actuator 140, the exhaust fan 150, and the cylinder 210 are clear to those skilled in the art and will not be described in detail here.
