Description

Technical Field

[0001] The invention relates to the technical field of die-casting dies, in particular to an aluminum profile die-casting die with an edge waste cutting function. Background Art

[0002] Die casting refers to a process in which molten metal is injected into a mold and then solidified under a certain pressure. Aluminum die casting molds are simple, efficient, and highly precise. They are widely used in aluminum processing and can manufacture various precision aluminum profiles, such as extruded aluminum profiles and drawn aluminum profiles. Die casting molds are mainly composed of medium-sized, cooling pipes, splash plates, height setters, push rods, etc. The manufacturing process is complicated and requires comprehensive consideration of processing conditions, mold structure, material selection and other factors. The cost is high and the production cycle is long, but the molding effect and product quality are excellent. Aluminum die casting molds can manufacture metal parts with complex shapes, clear contours, thin walls and deep cavities, and have high strength and hardness. Traditional aluminum die casting molds are designed and used separately according to the required die casting workpieces.

[0003] In combination with the above content, it should be explained that: in the process of die-casting aluminum profiles, traditional molds lack data collection and supervision and analysis of the aluminum profile forming process in the mold, which causes the mold to wear continuously under high load conditions, resulting in a lot of extended waste edges in the aluminum profiles after die-casting, which not only affects the demoulding and subsequent processing of the aluminum profiles, but also leaves local waste edge debris, causing accelerated damage to the mold during use;

[0004] In view of the above technical defects, a solution is now proposed. Summary of the invention

[0005] The purpose of the present invention is to provide an aluminum profile die-casting mold with an edge waste cutting function. By collecting data on the forming process of the aluminum profile in the die-casting mold device, the internal injection pressure value NLz and the pressure difference fluctuation value YCz are obtained, and the forming process of the aluminum profile is comprehensively supervised and analyzed before and during die-casting, that is, the collected data is compared and analyzed with the preset storage data, and relevant rating signals are obtained, and relevant components are controlled to perform compensatory operations accordingly. Therefore, the sealing degree between the fixed mold and the movable mold and the condition of the aluminum profile forming waste edge can be accurately judged, and the influence of abnormal waste edge on subsequent material removal can be effectively avoided. The excess waste edge of the aluminum profile can be cut and removed by using the flipped trimming module, which effectively avoids the waste edge residue being not discovered and cleaned in time, resulting in the continuous use of the subsequent mold, and the risk of mold deformation and damage, so as to solve the problem raised.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Embodiment 1: This embodiment is used to solve the problem of lack of data collection and supervision analysis of the aluminum profile forming process in the mold, which causes the mold to wear continuously under high load conditions, resulting in a large amount of extended waste edges in the aluminum profile after die-casting.

[0036] The control panel is internally provided with a processor, a data acquisition module, a data analysis module, a signal execution module and an early warning communication module; during the operation of the die-casting mold device, the data acquisition module detects the internal injection pressure value NLz at the bottom of the lower die groove 505 and the pressure difference fluctuation value YCz inside the anti-overflow groove 502, and sends the internal injection pressure value NLz and the pressure difference fluctuation value YCz to the data analysis module via the processor; 10 minutes during the operation of the die-casting mold device is set as the time threshold;

[0037] It should be noted that: the internal injection pressure value NLz is expressed as the maximum and minimum values ​​of the amount of aluminum liquid added to the die casting cavity by the injection valve 101 within the time threshold, and the value of the internal injection pressure value NLz reflects how much the aluminum liquid inside the die casting cavity is pressurized and injected, and the larger the value of the internal injection pressure value NLz is, the more it means that the aluminum liquid in the die casting cavity is pressurized and injected beyond the volume range of the die casting cavity, and the pressure difference fluctuation value YCz is expressed as the value of the pressure change inside the overflow tank obtained within the time threshold. In addition, the internal injection pressure value NLz is collected by a flow sensor installed inside the injection valve 101, and the pressure difference fluctuation value YCz is collected by a pressure sensor installed inside the overflow tank 502;

[0038] After receiving the internal injection pressure value NLz and the pressure difference fluctuation value YCz, the data analysis module immediately analyzes the risk efficiency of the die-casting mold device. The specific analysis process is as follows:

[0039] Obtain the internal injection pressure value NLz and pressure difference fluctuation value YCz within the time threshold, and use the formula The component damage risk coefficient JSx is obtained, wherein a and b are respectively the proportional coefficients of the internal injection pressure value NLz and the pressure difference fluctuation value YCz, a>b>0, JSx is expressed as the component damage risk coefficient, and the preset component damage risk coefficient YSx stored and entered is retrieved from the processor for comparison and analysis with the component damage risk coefficient JSx;

[0040] If the component damage risk coefficient JSx ≥ the preset component damage risk coefficient YSx, it is determined that the finished product of the die-casting mold device has an abnormal risk within the time threshold, and a trimming signal is generated. The generated signal is sent to the signal execution module and the early warning communication module through the processor. After receiving the trimming signal, the signal execution module immediately controls the rotating motor 203 to work;

[0041] The limit cylinder 202 contracts and releases the lock on the flip plate 205, and the rotating motor 203 drives the flip plate 205 to rotate 180 degrees through the rotating shaft 204 until the die-casting mold 3 and the trimming mold 4 are rotated and swapped, and the die-casting mold device further drives the movable mold 2 to slide down until the trimming mold 4 abuts against the fixed mold 1;

[0042] The upper die movable groove 402 abuts against the lower die groove 505 through the center groove, and the distance adjustment cylinder 404 drives the upper die movable groove 402 to slide down and abut against the lower die groove 505 to lock, exposing the excess waste material on the edge of the aluminum profile in the reserved cavity. The servo motor 405 drives the guide ring 406 to rotate through the coupling, and the guide ring 406 drives the slider to rotate and slide along the bottom of the reserved cavity. The slider drives the fine-tuning cylinder arm 408 and the cutting knife 409 to move in a circular trajectory along the reserved cavity. The transverse cylinder drives the fine-tuning cylinder arm 408 to slide along the top of the slider through the connecting piece to adjust the distance between the cutting knife 409 and the outer wall of the upper die movable groove 402. The fine-tuning cylinder arm 408 drives the cutting knife 409 to move up and down through the connecting piece, prompting the cutting knife 409 to cut into the edge waste material of the aluminum profile exposed in the reserved cavity.

[0043] The ventilation pipe 303 inside the trimming module 4 is connected with the waste suction pipe 407 and the suction plate 403 pipeline. The waste suction pipe 407 generates suction along the outer inner wall of the reserved cavity to absorb the scraps cut from the edge of the aluminum profile in the reserved cavity. After the 10-mesh filter on the outer inner wall of the reserved cavity, the scraps smaller than the mesh diameter are extracted along the waste suction pipe 407 and discharged centrally. The scraps larger than the mesh diameter are attached to the surface of the filter under the continuous suction. After the movable mold 2 slides up a certain distance, an external person uses a container to extend it to the bottom of the upper mold movable groove 402, stops the suction of the waste suction pipe 407, and the attached scraps fall into the container.

[0044] The suction plate 403 generates suction through the pipe fittings to absorb the aluminum profile into the upper mold movable groove 402. The distance adjustment cylinder 404 drives the upper mold movable groove 402 to slide upward slightly, so that the suction of the absorbed aluminum profile is loosened. The distance adjustment cylinder 404 is reset again, and the suction plate 403 disconnects the suction, and waits for the movable mold 2 to open, so that the aluminum profile can be quickly taken out.

[0045] After receiving the trimming signal, the early warning communication module immediately generates a text message of "waste edge abnormality / suspend damage inspection" and sends it to the display screen of the main controller, and controls the main controller to sound an alarm;

[0046] If the component damage risk coefficient JSx is less than the preset component damage risk coefficient YSx, no signal is generated.

[0047] Embodiment 2: This embodiment is used to solve the problem that there are many extended scrap edges in the aluminum profile after die-casting, which not only affects the demolding and subsequent processing of the aluminum profile, but also leaves local scrap edge debris, causing accelerated damage to the mold during use.
