Description

Technical Field

[0001] The utility model relates to the technical field of die-casting equipment, in particular to an integrated chip cleaning device suitable for aluminum alloy die-casting. Background Art

[0002] Die casting is a metal casting process characterized by applying high pressure to the molten metal in the mold cavity. The mold is usually made of a higher strength alloy, and the process is somewhat similar to injection molding. Most die castings are iron-free, such as zinc, copper, aluminum, magnesium, lead, tin, lead-tin alloys and their alloys. Depending on the type of die casting, a cold chamber die casting machine or a hot chamber die casting machine is required; the die casting machine is a machine used for pressure casting. It includes hot and cold chambers. The latter are divided into two types: vertical and horizontal. The die casting machine hydraulically injects the molten metal into the mold under pressure and cools it into shape. After the mold is opened, a solid metal casting can be obtained.

[0003] During the die-casting process, there are usually materials such as chips and slag attached to the mold. In the prior art, the mold cavity is only cleaned by spraying after the part is taken out. The cleaning mode is single, and the mold is still exposed to the air after cleaning, so that the chips suspended in the air or not settled in time may still fall back to the parting surface, eventually leading to the occurrence of flying materials.

[0004] In summary, there is an urgent need for an integrated chip cleaning device suitable for aluminum alloy die casting that can clean the parting surface in a closed environment and effectively reduce the probability of flying materials caused by uneven parting surface due to debris.

Figure 2 A chip cleaning device suitable for aluminum alloy die casting, comprising a clamping mechanism 1, an injection mechanism 2, and a mold 3. The clamping mechanism 1 is provided with the mold 3 for driving the die casting mold to close and open. The clamping mechanism 1 has sufficient clamping force to ensure that the parting surface 31 of the mold 3 will not expand during the injection filling process. The injection mechanism 2 is connected to the mold 3 and pushes the molten metal in the pressure chamber at a predetermined speed, so that the molten metal flows through the runner and the inner gate in the mold 3 under sufficient pressure to fill the mold cavity. Continue to transfer to the solidifying molten metal until the molten metal is completely solidified into the required die-casting. After the injection is completed, the injection punch will be reset; the mold 3 includes a fixed mold and a movable mold, which are respectively fixed on two opposite mold mounting plates 11 of the die-casting machine. The fixed mold has a straight runner connected to the nozzle or the pressure chamber, and the movable mold moves with the movable mold mounting plate to open and close the mold. When closing the mold, the movable mold and the fixed mold are closed to form a cavity and a casting system. The liquid metal fills the cavity under high pressure. When opening the mold, the movable mold is separated from the fixed mold, and the casting is pushed out by the ejection mechanism provided on the movable mold; it belongs to the prior art.

[0025] The mold clamping mechanism 1 is provided with a pre-sealing structure 12 on the mold mounting plate 11, and the pre-sealing structure 12 is movably connected to the mold mounting plate 11 through a spring structure, and the pre-sealing structure 12 can be retracted in the mold mounting plate 11 so that its surface is flush with the surface of the mold mounting plate 11, and negative pressure channels 13 are provided on the two diagonals of the pre-sealing structure 12, and the negative pressure channel 13 is provided with a suction force by an external negative pressure mechanism, including a first negative pressure port 131 and a second negative pressure port 132, and the first negative pressure port 131 and the second negative pressure port 132 are connected to each other. 132 is parallel to the parting surface 31 of the mold 3 adjacent to it. In some preferred embodiments, the four corners of the pre-sealing structure 12 are provided with the negative pressure channel 13, and the mold mounting plate 11 is provided with a retraction port 111 adapted to the negative pressure channel 13, for accommodating the negative pressure channel 13 after shrinkage. It should be understood that the material of the portion where the negative pressure channel 13 is connected to the pre-sealing structure 12 is consistent with that of the clamping mechanism 1, and extends to the outside of the die-casting machine, and its connection with the external negative pressure mechanism can be connected through a hose to facilitate its movement.

[0026] Working principle: After spraying the mold cavity, the mold is closed. During mold closing, since the pre-sealed structure 12 protrudes from the surface of the mold mounting plate 11, it is first fitted with the mold mounting plate 11 on the other side before the mold closing on the parting surface 31, so that a relatively closed adsorption cavity 121 is formed in the pre-sealed structure 12. At this time, during the mold closing process, the negative pressure channel 13 passes through the surface of the parting surface 31, and the negative pressure channel 13 is used to suck the adsorption cavity 121, so as to complete the suction cleaning of the parting surface 31, so as to reduce the probability of debris adhering to the parting surface 31, and since the adsorption cavity 121 is In a relatively closed space, no new pollutants will be deposited on the parting surface 31; it should be understood that the exhaust groove of the die-casting is usually the assembly gap of the core, push rod, etc., and will not affect the suction force, and when the exhaust groove is large, a relative blocking block can be set to block the exhaust groove, and after the parting surface 31 is molded, the blocking block can be removed; the integrated debris cleaning device suitable for aluminum alloy die-casting described in the utility model can clean the parting surface 31 in a relatively closed environment through the negative pressure channel 13, effectively reducing the probability of flying materials caused by uneven parting surface 31 due to debris.

[0027] In some preferred embodiments, the two mold mounting plates 11 for mounting the fixed mold and the movable mold are respectively provided with the pre-sealing structure 12, so that when the molds are closed, the two relative pre-sealing structures 12 are closed first, and the seal is made tighter under the action of the two sets of spring structures. Furthermore, the negative pressure channel 13 is provided on the pre-sealing structures 12 on both sides, so that the negative pressure channel 13 can completely pass through the two parting surfaces 31 when shrinking, thereby improving the cleaning accuracy.

[0028] In some preferred embodiments, in order to further adapt to the needs of die-casting, it should be understood that after the suction of the negative pressure mechanism, the mold cavity is in a relative vacuum state, which can provide additional locking force and further reduce the probability of flash formation; in some other embodiments, in order to maintain the air pressure balance in the mold cavity, an air intake channel is provided on the pre-sealing structure 12. The air intake channel has the same structure as the negative pressure channel 13 and can be arranged in the middle position of one side of the pre-sealing structure 12. During negative pressure suction, an equal amount of clean gas is input through the air intake channel to form convection with the negative pressure channel 13, which can not only take away the contaminants on the parting surface 31, but also maintain the stability of the internal air pressure.

[0029] It should be noted that: the debris cleaning integrated device suitable for aluminum alloy die casting of the utility model comprises a clamping mechanism 1 for driving the die casting mold to close and open; an injection mechanism 2 for pushing the molten metal in the pressure chamber at a predetermined speed, so that the molten metal flows through the runner and the inner gate in the mold 3 under sufficient pressure to fill the mold cavity; and a mold 3 for casting, wherein the clamping mechanism 1 comprises a mold mounting plate 11, and a pre-sealing structure 12 is provided on the mold mounting plate 11, and the pre-sealing structure 12 protrudes from the mold mounting plate 11, so that before the two parting surfaces 31 contact, the pre-sealing structure 12 is in contact with the mold mounting plate 11 on the other side, isolating the parting surface 31 and the contact between the model cavity and the outside air, and then negative pressure suction is performed on the interior through the negative pressure channel 13 to suck out the internal debris to avoid affecting the airtightness of the mold; the negative pressure channel 13 is arranged on the diagonal of the pre-sealing structure 12, so that the negative pressure mechanism can simultaneously provide suction to the parting surfaces 31 on both adjacent sides, and the cleaning coverage of the parting surfaces 31 can be achieved through two groups of the negative pressure channels 13. Preferably, negative pressure channels 13 can be set at all four corners to improve the cleaning ability; the pre-sealing structure 12 is also provided with an air inlet channel, which is connected to the adsorption chamber 121, and clean gas can be introduced into the adsorption chamber 121 to replenish the pressure lost due to suction by the negative pressure channel 13.

[0030] The above is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and supplements without departing from the principle of the present invention. These improvements and supplements should also be regarded as the protection scope of the present invention.
