Description

Technical Field

[0001] The invention relates to the technical field of molding die equipment, in particular to a die-casting molding die with a self-cleaning function. Background Art

[0002] Die casting is an efficient metal processing technology. It uses high pressure to quickly inject liquid or semi-liquid metal into the cavity of the die casting mold, and forms a precise casting after cooling and solidification. In the die casting process, the design and performance of the mold are crucial. Reasonable gate and runner design can ensure that the molten metal fills the cavity evenly and smoothly, and a good exhaust system can prevent gas from being trapped and causing casting defects. At the same time, the mold material must be resistant to high temperature and high pressure as well as good wear resistance and corrosion resistance. In order to prevent metal residues from sticking to the inner wall of the mold, surface coating and polishing are often used. The quality and molding effect of the casting can also be guaranteed by optimizing the die casting process parameters, such as accurately controlling the die casting temperature, pressure and speed. Die casting is widely used in many fields such as automobiles, aerospace, electronics, etc., and provides strong support for the production of high-quality and high-precision metal parts in modern manufacturing.

[0003] Die casting relies on precise and powerful die casting equipment. The core principle is to inject liquid aluminum alloy into the pre-designed mold cavity at a rapid speed under high pressure. Among them, the automotive structural parts produced by die casting include body structural parts, such as integrated die casting body and frame, engine parts include engine cylinder block and engine cylinder head, transmission system parts include transmission housing and clutch housing, chassis parts include subframe and suspension arm, interior parts and other parts include instrument panel frame, door inner panel and radiator housing. The reason why aluminum alloy has become the favorite of die casting in the manufacturing of automotive parts lies in its unique physical and chemical properties. The first is low density. Compared with traditional steel materials, the density of aluminum alloy is about one-third of that of traditional steel materials, which has made great contributions to the weight reduction of automobiles. The body frame, doors and other parts made of aluminum alloy die casting have greatly reduced the weight of the whole vehicle, effectively reducing energy consumption, improving endurance or fuel economy.

[0004] In the die-casting process, aluminum material is one of the most widely used metal materials. When there are material residues in the mold, the molten metal will flow around these residues. The presence of the residues destroys the normal filling state of the molten metal, making it impossible for the casting surface to form a smooth contour. At the same time, the residues themselves may also form sand holes on the casting surface. For example, when the residue part falls off and is involved in the molten metal, small pits similar to sand holes will be left on the casting surface. These pores and sand holes will reduce the density and strength of the casting, and may become stress concentration points during subsequent use, causing cracks or damage to the casting. After the die-casting is completed, it is generally necessary to manually clean the metal residues in the mold cavity. Due to the strong adhesion of the metal residues, it is difficult to manually clean them, and it is not easy to clean the metal residues in the cavity. Therefore, those skilled in the art have proposed a die-casting mold with a self-cleaning function to solve the above-mentioned technical problems. Summary of the invention

[0019] Working principle: After the metal parts are die-cast, a small amount of aluminum metal will remain inside the die-casting mold. At this time, the alkaline washing and dissolving mechanism is started. First, the staff controls the hydraulic cylinder on the side seat through the control device to start. The hydraulic cylinder retracts the rod on it while starting. The rod on the hydraulic cylinder retracts and drives the mold seat on it to move to both sides synchronously. The mold seat moves while the die-casting cavity in the mold seat is expanded. Then the staff pushes the mounting frame on the base to slide the mounting frame on the base to the position of the side seat. Then the air pump on the mounting frame is started. The mounting frame pressurizes the alkaline solution tank through the connecting pipe. The sodium hydroxide solution in the alkaline solution tank passes through After pressurization, it enters the spray seat through the delivery pipe, and then the sodium hydroxide solution entering the spray seat is diverted and sprayed on the surface of the die-casting cavity in the mold seat. As time goes by, the sodium hydroxide solution in the die-casting cavity slowly flows to various positions of the die-casting cavity. In this process, the sodium hydroxide solution will react with the residual grease components in the molten metal in the die-casting cavity, the acidic components in the release agent, and the residual aluminum metal material therein, thereby dissolving them, thereby completing the alkaline washing and dissolution treatment of the inside of the die-casting mold cavity; then the residue cleaning mechanism is started, first the servo motor on the base is started, and the shaft of the servo motor drives the screw in the moving groove to rotate synchronously while rotating, and the screw rotates. At the same time, it drives the moving seat in the moving groove thereon to move toward the middle of the base. Then, when the moving seat moves to the middle position of the base, the moving seat stops moving. At the same time, the staff adjusts the mold seat to be close to the mounting disk in the middle through the control equipment, and then the driving motor in the moving seat is started. The rotating shaft of the driving motor drives the transmission shaft on the moving seat to rotate synchronously while rotating. The transmission shaft drives the main bevel gear thereon to rotate synchronously while rotating. The main bevel gear drives the auxiliary bevel gears on both sides and the mounting disk to rotate synchronously while rotating. The mounting disk drives the sponge cleaning seat thereon to rotate synchronously while rotating. The sponge cleaning seat contacts the die-casting cavity in the mold seat while rotating to produce corresponding The metal residue in the die-casting cavity is cleaned by alkali washing and dissolution, and then when the mounting plate rotates, when the counterweight block in the sliding groove rotates to a high position, the counterweight block moves downward due to gravity, and the counterweight block squeezes the inclined slide seat in the plug-in groove while moving downward, so that the inclined slide seat slides toward the position of the sponge cleaning seat, and at the same time hits the metal conduction plate inside the sponge cleaning seat, so that the vibration generated by the impact is transmitted to the mold seat, accelerating the separation speed of the metal residue in the die-casting cavity, and at the same time, the rebound force generated by the inclined slide seat after the impact makes it reset again, and then when the counterweight block in the sliding groove rotates to a high position again, the above operation is repeated to complete the cleaning of the residue dissolved in the die-casting cavity;After that, the residual separation mechanism is started. First, the staff starts the hydraulic cylinder on the side seat through the control equipment. After the hydraulic cylinder is started, the rod on it is pushed out. While pushing out, the rod on the hydraulic cylinder drives the mold seat on it to reset and close, thereby forming a closed die-casting cavity. At this time, the staff places the rubber sleeve seat 2 on the telescopic tube on the injection port on the mold seat, and then starts the fan on the base. When the fan is started, the air in the installation box is pumped through the connecting pipe, thereby forming a short negative pressure state inside the installation box and the die-casting cavity. At this time, the air in the die-casting cavity enters the interior of the installation box through the rubber sleeve seat 2 and the telescopic tube. As the fan keeps pumping, the air in the die-casting cavity carries the metal residue dissolved and cleaned out by vibration separation in the die-casting cavity into the installation box, and then enters the installation box through the fixed frame The filter cotton seat separates and filters the metal residues carried in the air step by step, so as to complete the separation of the residual substances inside the mold cavity; then the cavity detection mechanism is started, and the staff first fits the rubber sleeve seat on the injection port on the mold seat, and then starts the pumping pump on the base. When the pumping pump is started, the wax dissolved in the wax melting box is transported to the die-casting cavity of the mold seat through the connecting pipe, and the die-casting cavity in the mold seat is filled with the wax in the wax melting box. After the wax in the die-casting cavity is completely solidified, the staff opens the mold seat, takes out the wax mold in the die-casting cavity, and adheres the metal residues remaining in the cavity through the wax in the die-casting cavity. The staff can also judge and detect the cleaning of the metal residues in the cavity by observing the shape of the wax mold, so as to complete the final treatment and detection of the metal residues in the mold cavity. ;

[0020] The present invention provides a die-casting mold with a self-cleaning function. It has the following beneficial effects:

[0021] 1. The present invention has many significant advantages by adding and setting up an alkali washing and dissolving mechanism. In terms of cleaning effect, it can efficiently remove grease and aluminum residues on the surface of the mold, providing a strong guarantee for maintaining the mold in a good clean state. From the perspective of safety performance, the alkali washing method shows excellent characteristics compared with acid washing. It will not release a large amount of irritating gas, thereby greatly reducing the potential threat to the health of operators and the degree of corrosion to equipment. This treatment method enables the alkali washing operation to be smoothly carried out in a conventional working environment without the need to be equipped with complex and expensive ventilation equipment, effectively reducing the equipment purchase and operation and maintenance costs. In terms of operational flexibility, the operator can accurately and conveniently adjust the alkali solution concentration and cleaning time according to the different degrees of aluminum residue contamination on the mold, thereby achieving precise control of the cleaning effect, ensuring that the mold can reach the ideal cleaning standard under various working conditions, and significantly improving the overall efficiency and quality level of mold maintenance work.

[0022] 2. The present invention adds and sets a residue cleaning mechanism. After the alkaline washing treatment, it works in coordination with the rotation cleaning effect of the sponge seat and the vibration conduction mechanism. The rotation of the sponge seat can directly wipe and clean the inside of the mold, while the vibration conduction can prompt the metal residue to be more efficiently separated from the inner wall of the mold and other parts. The two complement each other, significantly accelerate the separation speed of the metal residue, and greatly improve the separation effect. This not only ensures the thoroughness of the cleaning of the inside of the mold, effectively reduces the adverse effects of residue residue on the mold and subsequent die-casting processes, but also improves the mold maintenance efficiency, laying a solid foundation for stable and high-quality die-casting production.

[0023] 3. The present invention adds and sets a residue separation mechanism. After the residue cleaning mechanism is processed, the mechanism forms a vacuum negative pressure in the die-casting cavity by exhausting air. This negative pressure state is not only conducive to the efficient extraction of the dissolved and separated metal residues remaining in the die-casting cavity, but also can simultaneously realize the separation and collection of the residues during the gas discharge process, and with the help of the filter cotton seat, the residues can be accurately captured to prevent their diffusion and secondary pollution. Therefore, this design can not only greatly improve the cleaning efficiency and thoroughness of the metal residues and optimize the cleaning process of the die-casting mold, but also ensure the subsequent use performance of the mold, extend the service life of the mold, and improve the overall quality and stability of the die-casting production.

[0024] 4. The present invention adds and sets a cavity detection mechanism. After the residual separation mechanism completes the internal processing of the mold, the mechanism injects molten wax into the mold cavity. On the one hand, the molten wax can effectively adhere to the residual metal residue, especially those parts that are difficult to clean, greatly improving the integrity and accuracy of mold cleaning. On the other hand, by utilizing the molding characteristics of the wax mold, the staff can intuitively detect and judge the internal condition of the cavity, such as checking whether the cavity has deformation, damage or dimensional deviation, so as to timely discover potential defects of the mold and repair them, effectively ensuring the quality of the mold and improving the accuracy and stability of subsequent die-casting products.
