Description

Technical Field

[0001] The present invention relates to the technical field of die-casting molding, and specifically to an isothermal cooling die-casting molding device and method for a necked aluminum flange. Background Art

[0002] A die-casting molding device is a device used for metal die-casting. It allows molten metal to be rapidly filled into a mold cavity under high pressure and obtains precise metal parts after cooling and solidification. The workpieces formed by die-casting are widely used in multiple industries such as automobiles, aviation, electronics, and household appliances.

[0003] In the existing die-casting device, during the process of injecting molten metal, the molten metal flows in the runner, and there will be heat loss, resulting in the temperature drop and condensation of the molten metal after it is transported to the die-casting cavity, thus affecting the die-casting quality. Moreover, during the die-casting process, the diameter of the runner is relatively large, resulting in more machining residues connected to the formed workpiece. Summary of the Invention

[0004] The purpose of the present invention is to provide an isothermal cooling die-casting molding device and method for a necked aluminum flange to solve the problems raised in the prior art.

[0005] To achieve the above purpose, the present invention provides the following technical solutions:

[0006] An isothermal cooling die-casting molding device for a necked aluminum flange includes a die-casting table. Inside the die-casting table, there are an upper mold and a lower mold. The upper mold is a movable mold, and the lower mold is a fixed mold. A hydraulic cylinder is arranged on one side of the die-casting table close to the upper mold. The push rod of the hydraulic cylinder is connected to the upper mold. A molten cavity is arranged outside the die-casting table.

[0007] Preferably, the upper mold and the lower mold jointly form a die-casting cavity. Inside the die-casting cavity, there is a conveying body. The outer wall diameter of the conveying body is equal to the inner wall diameter of the flange.

[0008] After the previous die-cast flange is taken away, the controller controls the hydraulic cylinder on the die-casting table to start. The push rod of the hydraulic cylinder drives the upper mold to move. The upper mold moves towards the side close to the lower mold. Finally, the upper mold and the lower mold complete the mold closing, so that the upper mold and the lower mold jointly form a die-casting cavity.

[0009] Preferably, the conveying body is composed of an upper pressing body and a lower pressing body. Inside the upper pressing body, there is a conveying pipe. On one side of the conveying pipe far from the lower pressing body, there is a piston rod. The piston rod is slidably and sealingly connected to the conveying pipe. On the side of the conveying pipe far from the piston rod, there is an electric cylinder. The push rod of the electric cylinder is connected to the piston rod. There is an infusion port on the top of the upper mold, and the infusion port is communicated with the conveying pipe.

[0010] The molten metal is conveyed to the conveying pipe through the melting cavity. Subsequently, the controller controls the electric cylinder to start. The push rod in the electric cylinder drives the piston rod to move, causing the piston rod to move along the conveying pipe towards the side close to the conveying body. During the movement of the piston rod, the molten metal is pushed to move, and injection molding treatment is performed on the molten metal. When the piston rod moves to the maximum formation, that is, when the depression and the protrusion fit, at this time, the die-casting cavity is filled with the molten metal. Subsequently, the piston rod remains stationary to complete the pressure holding treatment of the die-casting cavity.

[0011] Preferably, a plurality of spiral grooves are provided at the bottom of the upper pressing body and the top of the lower pressing body. The upper and lower spiral grooves are combined into a spiral pipe, and the conveying pipe is communicated with the die-casting cavity through the spiral grooves.

[0012] After the upper die and the lower die are closed, the spiral grooves arranged on the upper and lower sides are combined into a spiral pipe, so that during the conveying process of the molten metal, the molten metal can pass through the spiral pipe and be conveyed from the conveying pipe to the die-casting cavity. Since the diameter of the spiral pipe is small, when the molten metal flows in the spiral pipe, the flow rate of the molten metal increases. When the molten metal flows out from the side of the spiral pipe far from the conveying pipe, the flow rate of the molten metal is the fastest at this time. Then, the molten metal moves towards the side of the die-casting cavity far from the conveying pipe in the form of spraying, so that the molten metal first fills the edge of the die-casting cavity and then fills the center of the die-casting cavity, improving the quality of flange die-casting.

[0013] Preferably, a liquid spraying port is provided between two adjacent spiral grooves. The surface of the liquid spraying port is provided with an inclined surface. The height of the inclined surface close to the die-casting cavity side is greater than the height of the inclined surface close to the conveying pipe side. A degreasing cavity is further provided outside the die-casting table, and a suction pump is provided in the degreasing cavity. The suction pump is communicated with the liquid spraying port through a pipeline.

[0014] When the upper die moves towards the side close to the lower die, the controller controls the suction pump to start. The suction pump extracts the degreasing agent in the degreasing cavity and conveys it to the liquid spraying port through the pipeline, and then sprays it out through the liquid spraying port. Since the surface of the liquid spraying port is provided with an inclined surface, and the height of the inclined surface close to the die-casting cavity side is greater than the height of the inclined surface close to the conveying pipe side, the liquid spraying port on the lower die sprays upwards to the bottom of the upper die, and the liquid spraying port on the upper die sprays downwards to the top of the lower die. During the process of closing the upper die and the lower die, the spraying of the degreasing agent is completed, shortening the time required for the process flow.

[0015] Preferably, a protrusion is provided at the center of the lower pressing body, and a depression is provided on the side of the piston rod close to the protrusion. The protrusion and the depression are engaged.

[0016] During die-casting, the electromagnet in the moving cavity is de-energized. As a result, the axes of the ball, the moving column, and the rotating ball are aligned. At this time, the air extraction pipe is located inside the protrusion, and the protrusion and the rotating ball form an integral body. When the piston rod pushes the molten metal to move along the delivery pipe, when the molten metal moves to the junction of the protrusion and the spiral groove, since the protrusion occupies the space inside the delivery pipe, the moving space of the molten metal is compressed, and thus the flow rate of the molten metal increases, enabling the molten metal to be transported from the delivery pipe to the die-casting cavity through the spiral pipe formed by the spiral groove at a faster speed, avoiding heat loss of the molten metal during transportation.

[0017] Preferably, a moving cavity is provided inside the pressing body. A moving column is arranged inside the moving cavity. A ball is provided at the bottom of the moving column. The moving column is slidably connected to the moving cavity through the ball. A plurality of electromagnets are provided at the bottom of the moving cavity. The ball is a magnetic conductor.

[0018] When the electromagnet is energized to generate magnetic force, the magnetic force attracts the ball acting as a magnetic conductor, causing the ball to slide along the bottom of the moving cavity. During the sliding of the ball, the moving column is driven to deflect. After the moving column deflects, the rotating ball will also deflect, thereby driving the movement of the air extraction pipe to complete the connection between the delivery pipe and the moving cavity.

[0019] Preferably, a rotating ball is provided at the top of the moving column. The rotating ball is rotatably connected to the protrusion. A plurality of air extraction pipes are provided on one side of the rotating ball close to the moving cavity. One end of the air extraction pipe communicates with the delivery pipe, and the other end of the air extraction pipe communicates with the moving cavity. An air pump is provided at the bottom of the lower mold. The air pump is connected to the moving cavity through a pipeline.

[0020] The air pump is started under the action of the controller. The air pump extracts the air in the moving cavity. While the air is being extracted, the electromagnet at the bottom of the moving cavity is energized. By energizing the electromagnet to generate magnetic force, the ball is affected by the magnetic force and rotates. After the ball rotates, it drives the moving column to deflect. After the moving column deflects, it drives the rotating ball to rotate. Then, the rotating ball drives one end of the air extraction pipe to rotate from the side inside the protrusion to the side located in the delivery pipe. At this time, the air extraction pipe connects the delivery pipe and the moving cavity, and the gas in the die-casting cavity and the delivery pipe can be transported to the moving cavity through the air extraction pipe, thereby completing the vacuum treatment of the die-casting cavity. And due to the sequential energization of the electromagnets, the rotating ball can rotate around the axis of the protrusion, enabling the plurality of air extraction pipes to extract the gas in different directions. The extracted gas is transported to the moving cavity and will be affected by the heat of the electromagnet. Thus, the gas can be heated in the moving cavity and finally transported to the steam cavity through the pipeline for heat preservation treatment, thereby improving the utilization rate of resources.

[0021] Preferably, steam cavities are provided on one side of the upper die and the lower die close to the die casting cavity. The steam cavities are filled with steam through pipelines. The distance between the side of the steam cavity away from the conveying body and the die casting cavity is smaller than the distance between the side of the steam cavity close to the conveying body and the die casting cavity.

[0022] By conveying steam into the steam cavities, the temperature carried by the steam can be transferred to the die casting cavity through the upper die and the lower die, causing the temperature in the die casting cavity to rise, avoiding the rapid condensation of the molten metal when it meets cold, thus causing die casting defects and affecting the die casting quality. Moreover, the distance between the side of the steam cavity away from the conveying body and the die casting cavity is smaller than the distance between the side of the steam cavity close to the conveying body and the die casting cavity, increasing the heat received by the inner wall of the die casting cavity on the farther side of the spiral groove, thereby reducing the temperature difference between the edge position and the center position of the die casting cavity, and thus improving the quality of flange die casting.

[0023] A forming method for an isothermal cooling die casting forming device of a necked aluminum flange, characterized in that:

[0024] The forming method includes the following specific steps:

[0025] S1. The upper die moves towards the side close to the lower die;

[0026] S2. While the upper die is moving, a degreasing agent is sprayed from the liquid spraying port;

[0027] S3. After the upper die and the lower die are closed, the die casting cavity is evacuated;

[0028] S4. The piston rod pushes the molten metal for injection;

[0029] S5. After die casting is completed, the upper die and the lower die are separated.

[0030] Compared with the prior art, the beneficial effects of the present invention are:

[0031] 1. Since the diameter of the spiral tube is small, when the molten metal flows in the spiral tube, the flow rate of the molten metal is accelerated. When the molten metal flows out from the side of the spiral tube away from the conveying tube, the flow rate of the molten metal is the fastest at this time. Furthermore, the molten metal moves towards the side of the die casting cavity away from the conveying tube in the form of spraying, so that the molten metal first fills the edge of the die casting cavity and then fills the center of the die casting cavity, improving the quality of flange die casting.

[0032] 2. Since the protrusions occupy the space inside the conveying tube, the moving space of the molten metal is compressed, and thus the flow rate of the molten metal is accelerated, enabling the molten metal to be transported from the conveying tube to the die casting cavity through the spiral tube composed of spiral grooves faster, and being transported at a faster speed, avoiding the loss of heat of the molten metal during the transportation process.

[0033] 3. Due to the sequential energization of the electromagnets, the rotating ball can rotate around the axis of the protrusion, enabling several air extraction pipes to extract air from different orientations. The extracted air is transported into the moving cavity and will be affected by the heat of the electromagnets. Thus, the air can be heated within the moving cavity and finally transported through a pipeline to the steam cavity for heat preservation treatment, thereby improving the utilization rate of resources.

[0049] As a specific embodiment of the present invention, on the bottom of the upper pressing body 15 and the top of the lower pressing body 16, there are a number of spiral grooves 19. The upper and lower spiral grooves 19 together form a spiral pipe, and the conveying pipe 17 is communicated with the die-casting cavity 13 through the spiral grooves 19.

[0050] As a specific embodiment of the present invention, between two adjacent spiral grooves 19, there is a liquid spraying port 20. The surface of the liquid spraying port 20 is provided with an inclined surface. The height of the inclined surface on the side close to the die-casting cavity 13 is greater than the height of the inclined surface on the side close to the conveying pipe 17. Outside the die-casting table 1, there is also a degreasing cavity.

[0052] As a specific embodiment of the present invention, a rotating ball 26 is arranged at the top of the moving column 24. The rotating ball 26 is rotatably connected to the protrusion 21. A plurality of air extraction pipes 27 are arranged on one side of the rotating ball 26 close to the moving cavity 23. One end of the air extraction pipe 27 communicates with the conveying pipe 17, and the other end of the air extraction pipe 27 communicates with the moving cavity 23. An air pump is arranged at the bottom of the lower die 12. The air pump is communicated with the moving cavity 23 through a pipeline.

[0053] A forming method for an isothermal cooling die-casting forming device of a necked aluminum flange, characterized in that:

[0054] The forming method includes the following specific steps:

[0055] S1. The upper die 11 moves towards the lower die 12.

[0056] S2. While the upper die 11 is moving, the degreasing agent is sprayed out from the liquid spraying port 20.

[0057] S3. After the upper die 11 and the lower die 12 are closed, the die-casting cavity 13 is evacuated.

[0058] S4. The piston rod 18 pushes the molten metal for injection.

[0059] S5. After die-casting is completed, the upper die 11 is separated from the lower die 12.

[0060] The working principle of the present invention:

[0061] After the previous die-cast flange is taken away, the controller controls the hydraulic cylinder on the die-casting table 1 to start. The push rod of the hydraulic cylinder drives the upper die 11 to move. The upper die 11 moves towards the lower die 12. Finally, the upper die 11 and the lower die 12 are closed, so that the upper die 11 and the lower die 12 jointly form the die-casting cavity 13.

[0062] When the upper die 11 moves towards the lower die 12, the controller controls the suction pump to start. The suction pump extracts the degreasing agent in the degreasing chamber, transports it through the pipeline to the liquid spraying port 20, and then sprays it outwards through the liquid spraying port 20. Since the surface of the liquid spraying port 20 is provided with an inclined surface, and the height of the inclined surface close to the die-casting cavity 13 is greater than the height of the inclined surface close to the delivery pipe 17, the liquid spraying port 20 on the lower die 12 sprays upwards towards the bottom of the upper die 11, and the liquid spraying port 20 on the upper die 11 sprays downwards towards the top of the lower die 12. During the process of the upper die 11 and the lower die 12 being closed, the spraying of the degreasing agent is completed;

[0063] The pump starts under the action of the controller. The air pump extracts the air in the moving chamber 23. While the gas is being extracted, the electromagnet at the bottom of the moving chamber 23 is energized. By the electromagnet being energized to generate magnetic force, the ball 25 is affected by the magnetic force and rotates. After the ball 25 rotates, it drives the moving column 24 to deflect. After the moving column 24 deflects, it drives the rotating ball 26 to rotate. Furthermore, the rotating ball 26 drives one end of the air extraction pipe 27 to rotate from the side inside the protrusion 21 to the side of the delivery pipe 17. At this time, the air extraction pipe 27 connects the delivery pipe 17 and the moving chamber 23, and the gas in the die-casting cavity 13 and the delivery pipe 17 can be transported to the moving chamber 23 through the air extraction pipe 27, thereby completing the vacuum treatment of the die-casting cavity 13. And due to the sequential energization of the electromagnet, the rotating ball 26 can rotate around the axis of the protrusion 21, so that several air extraction pipes 27 perform air extraction treatment on the gas in different directions. The extracted gas is transported into the moving chamber 23 and will be affected by the heat of the electromagnet. Furthermore, the gas can be heated in the moving chamber 23 and finally transported to the steam chamber 28 through the pipeline for heat preservation treatment;

[0064] After the upper die 11 and the lower die 12 are closed, the spiral grooves 19 arranged on the upper and lower sides are combined into a spiral pipe, so that during the transportation of the molten metal, the molten metal can be transported from the delivery pipe 17 to the die-casting cavity 13 through the spiral pipe. Since the diameter of the spiral pipe is small, when the molten metal flows in the spiral pipe, the flow rate of the molten metal increases. When the molten metal flows out from the side of the spiral pipe far from the delivery pipe 17, the flow rate of the molten metal is the fastest at this time. Furthermore, the molten metal moves towards the side of the die-casting cavity 13 far from the delivery pipe 17 in the form of spraying, so that the molten metal first fills the edge of the die-casting cavity 13 and then fills the center of the die-casting cavity 13;

[0065] During die casting, the electromagnet in the moving cavity 23 is de-energized. As a result, the axes of the ball 25, the moving column 24, and the rotating ball 26 are in a coincident state. At this time, the air extraction pipe 27 is located inside the protrusion 21, and the protrusion 21 and the rotating ball 26 form an integral body. When the piston rod 18 pushes the molten metal to move along the delivery pipe 17, when the molten metal moves to the junction of the protrusion 21 and the spiral groove 19, since the protrusion 21 occupies the space inside the delivery pipe 17, the moving space of the molten metal is compressed. As a result, the flow rate of the molten metal increases, enabling the molten metal to be transported from the delivery pipe 17 to the die casting cavity 13 through the spiral pipe formed by the spiral grooves 19 at a faster speed for faster transportation.

[0066] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present invention. Any reference signs in the claims should not be construed as limiting the claimed rights.
