Description

Technical Field

[0001] The invention relates to the technical field of die-casting machines, in particular to cleaning equipment for die-casting machines. Background Art

[0002] A die-casting machine is a machine used for pressure casting, including a hot pressing chamber and a cold pressing chamber, which are later divided into vertical and horizontal types. The die-casting machine hydraulically injects molten metal into a mold under pressure for cooling and forming. After the mold is opened, a solid metal casting can be obtained. It was originally used for die-casting lead type. With the progress of science and technology and industrial production, especially with the development of industries such as automobiles, motorcycles and home appliances, die-casting technology has achieved extremely rapid development.

[0003] The die-casting machine needs to clean the mold before and after use to prevent oil and dust from appearing on the die-casting surface of the mold during die-casting, which may cause unqualified die-castings. However, it is currently cleaned manually, which has low cleaning efficiency and produces some harmful gases after die-casting. When inhaled, it will affect people's health.

[0004] In order to solve the above problems, patent number CN107983693B proposes a die-casting machine that is easy to clean the mold. Although vertical water spray holes and inclined water spray holes are set to clean the surface and inner end face of the mold, the angle cannot be freely adjusted according to the mold opening length for spraying. When the mold opening length is long, the inclined water spray hole cannot reach the inner end of the mold surface. At present, the exhaust gas generated by the die-casting machine requires additional equipment for suction and discharge, which occupies a large space and wastes costs. Therefore, it is necessary to design a cleaning device for the die-casting machine that can automatically adjust the water spray angle and integrate water spray and air suction.

[0039] Before the die-casting machine 1 starts die-casting, the mold needs to be cleaned, and the length of the mold is input into the control box 4. The control module controls the output end of the electric push rod 5 to extend until it reaches the previously set distance. The first through hole 26 is now interconnected with the water hole 21. The control module controls the second water pump to open, and water is sprayed from the nozzle 29 to rinse the mold surface until the liquid level sensor 15 detects that the sewage in the collection box 16 reaches the previously set water level.

The control module controls the output end of the left motor 24 to rotate clockwise, and the output end of the right motor 24 to rotate counterclockwise. The rotation angle of the output end of the left motor 24 is automatically adjusted according to the length of the mold opening, until the rotation angle of the output end of the left motor 24 reaches the previously set distance, the control module controls the second water pump to open, and water is sprayed from the nozzle 29 to rinse the inside of the mold. The end face is flushed until the liquid level sensor 15 detects that the water source inside the collection box 16 reaches the previously set distance, the control module controls the output ends of the left motor 24 and the right motor 24 to return to their positions, the second water pump stops working, and the first water pump 9 and the solenoid valve 17 are turned on. The first water pump 9 filters the sewage inside the collection box 16 from the water purifier 18 and re-transports it to the inside of the bucket 8 until the liquid level sensor 15 detects that the water level inside the collection box 16 reaches the previously set value, the control module controls the first water pump 9 to stop working, closes the solenoid valve 17, controls the die-casting machine 1 to close the mold, and controls the output end of the electric push rod 5 to retract. At this time, the air hole 19 is interconnected with the first through hole 26. When the laser emitter 32 detects that the laser length is greater than the mold length, the control module controls the air pump 6 to open, and the nozzle 29 begins to absorb exhaust gas into the air purifier 7 until the laser emitter 32 detects that the laser length is equal to the mold length, and the control module controls the air pump 6 to stop working.

[0040] The following steps are involved:

[0041] S1: Cleaning the surface of the mold inside the die-casting machine 1;

[0042] S2: Cleaning the inner end surface of the internal mold of the die-casting machine 1;

[0043] S3: Filter the sewage and transport it to the inside of the bucket 8;

[0044] S4: switch to cleaning mode;

[0045] S5: Absorbing waste gas generated by die-casting of the die-casting machine 1;

[0046] S6: Repeat S1 to S5 to clean different molds.

[0047] Specifically, the method of cleaning the inner end surface of the mold of S2 is as follows:

[0048] When the two molds are opened, the opening lengths are L1 and L2 respectively, L2 is greater than L1, the rotation angles of the output end of the left motor 24 are C1 and C2, C2 is greater than C1, when the laser emitter 32 detects that the mold opening length is L1, the rotation angle of the output end of the left motor 24 is C1, when the laser emitter 32 detects that the mold opening length is L2, the rotation angle of the output end of the left motor 24 is C2, the longer the mold opening length, the greater the rotation angle of the left motor 24, so that the nozzle 29 is aligned with the inner end face of the mold.

[0049] Specifically, the method of S4 conversion mode is as follows:

[0050] The distance between the water hole 21 and the air hole 19 is set to 5 cm. When the output end of the electric push rod 5 extends 5 cm, it is converted into a water spray mode. When the output end of the electric push rod 5 retracts 5 cm, it is converted into an air suction mode. The mode can be freely adjusted according to the cleaning condition of the mold.

[0051] Specifically, the exhaust gas absorption method of S5 is as follows:

[0052] The power of air pump 6 is set to W1 and W2, W2 is greater than W1, the sizes of the two molds are S1 and S2 respectively, S2 is greater than S1, when the size of the input mold is S1, the power of air pump 6 is adjusted to W1, when the size of the input mold is S2, the power of air pump 6 is adjusted to W2, the larger the mold, the more waste gas is generated during die casting, the greater the working power of air pump 6, the higher the efficiency of sucking waste gas, so the air pump 6 can automatically adjust the working power according to the size of the mold.

A cleaning device for a die casting machine according to claim 6, characterized in that: The power of the air pump (6) is set to W1 and W2, W2>W1, the sizes of the two molds are S1 and S2 respectively, S2>S1, when the size of the input mold is S1, the power of the air pump (6) is adjusted to W1, when the size of the input mold is S2, the power of the air pump (6) is adjusted to W2, the larger the mold, the more waste gas is generated during die casting, and the greater the working power of the air pump (6), the higher the efficiency of sucking waste gas.
