DETAILED DESCRIPTION

[0030] The following describes two implementation modes of the present application in detail with reference to the accompanying drawings.

[0031] The first implementation method:

[0032] Figure 1-7 As shown, it includes a main shell 1, and both ends of the main shell 1 are respectively connected to a leaching pool 2 and a flushing mechanism 3, the leaching pool 2 includes a main pool body embedded in the main shell 1, a plurality of upper nozzles are connected to the main pool body, and a circulation pump is connected between the main pool body and the upper nozzles;

[0033] The flushing mechanism 3 includes a liquid collecting pipe 301, a plurality of flushing nozzles 302 are installed at the upper end of the liquid collecting pipe 301, and the plurality of flushing nozzles 302 are arranged in a row at the same level. The flushing nozzles 302 include a plurality of horizontal conduits perpendicular to the electric guide rail 401, and a plurality of evenly distributed and matched high-pressure nozzles are installed on the horizontal conduits. A liquid discharge pipe 303 is installed in the middle of the liquid collecting pipe 301; the output end of the liquid discharge pipe 303 is connected to a recovery tank 5, and a pH value detector 6 is installed in the recovery tank 5; the output end of the recovery tank 5 is connected to a waste liquid pipe, and a conduit is connected between the main tank body and the waste liquid pipe;

[0034] The upper surface of the grille plate 405 is provided with a water guide groove communicating with two adjacent grille holes, and the water in the grille hole is guided to flow to the adjacent grille hole through the water guide groove, so as to facilitate the discharge of flushing water. The multiple flushing nozzles 302 of this scheme can be set into two groups, and the two adjacent flushing nozzles 302 are different groups. The two groups of flushing nozzles 302 work alternately. When the flushing nozzle 302 is working, the water sprayed by it is convenient to be discharged from the adjacent non-working flushing nozzle 302;

[0035] A liquid storage tank is detachably installed in the main housing 1, and the liquid storage tank is used to store cleaning liquid. The main tank body and the flushing nozzle 302 are both connected to the liquid storage tank; a liquid pump with an electromagnetic three-way valve is installed on the liquid storage tank, and two output ends of the electromagnetic three-way valve are respectively connected to the immersion tank 2 and the flushing nozzle 302;

[0036] The upper end of the main shell 1 is connected to a guide frame 4 that matches the immersion tank 2 and the flushing mechanism 3, and the guide frame 4 includes a pair of electric guide rails 401, and a movable frame 402 is connected between the movable ends of the pair of electric guide rails 401, and a pair of electric lifting frames 403 are installed on the movable frame 402. The telescopic ends of the pair of electric lifting frames 403 are connected to side fixing plates 404, and a grid plate 405 is connected between the pair of side fixing plates 404, and the grid holes on the grid plate 405 match the flushing nozzle 302. After the grid plate 405 is lowered, the high-pressure nozzle on the flushing nozzle 302 can be inserted into the grid hole; a through hole matching the grid plate 405 is opened in the middle of the movable frame 402. When the grid plate 405 is in the initial position, the flushing nozzle 302 has no contact with the grid plate 405.

[0037] A secondary enclosure shell matching the position of the immersion tank 2 is installed on the main shell 1, and a fan is installed in the secondary enclosure shell to suck away dust on the surface of the mold.

[0038] The pH value detector 6 comprises an electric push rod installed on the upper end of the inner wall of the recovery tank 5 , a pH value detection probe is installed on the movable end of the electric push rod, and a liquid level sensor connected to the electric push rod signal is installed in the recovery tank 5 .

[0039] The main housing 1 is hingedly connected with a sealing cover that matches the position of the flushing mechanism 3, and a door magnetic sensor is installed on the sealing cover.

[0040] The cross-section of the side fixing plate 404 is L-shaped, and a plurality of sliding rods are inserted into the side end of the side fixing plate 404, and a magnetic clamp is connected between the plurality of sliding rods. An electromagnet matching the magnetic clamp is installed on the side fixing plate 404, and the magnetic clamp is used to clamp the mold; optionally, during the clamping process of the magnetic clamp, the mold can be swung left and right by controlling the operation of the two electromagnets, so that the part of the mold covered by the grille on the grille plate 405 can be easily washed.

[0041] Before the present solution works, the sealing cover on the upper side of the flushing mechanism 3 is opened, and then the mold to be cleaned is placed on the grid plate 405 between a pair of side fixing plates 404, with the mold cavity facing the grid plate 405, and a pair of magnetic clamps are used to fix the mold; at this time, the sealing cover is closed and the cleaning is ready.

[0042] When cleaning the mold, the electric guide rail 401 is controlled to move the mold to the upper part of the immersion tank 2, and a pair of electric lifting frames 403 are controlled to lower the mold to below the liquid level of the cleaning agent in the main tank. After the mold is immersed for a set time, the mold is reset to the flushing mechanism 3; then the grid plate 405 is moved downward by a set distance so that the grid holes on the grid plate 405 match the flushing nozzle 302; the high-pressure nozzle on the flushing nozzle 302 in the flushing mechanism 3 is inserted into the grid hole, and at this time, the mold cavity of the mold is flushed by the high-pressure nozzle on the flushing nozzle 302.

[0043] This embodiment weakens the oil stains on the entire mold by soaking and cleaning first, and then flushing the mold cavity, which makes it easy to ensure that the mold is fully cleaned.

[0044] Second implementation method:

[0045] Figure 5-8 As shown, it also includes a cleaning monitoring system, which includes a controller, to which a data processing module, a detection module and a cleaning control module are connected; the guide frame 4, the immersion tank 2 and the flushing mechanism 3 are all connected to the cleaning control module signal, and a PH detection probe is installed in the main tank body, and the PH detection probe, the pH value detector 6 and the liquid level sensor are all connected to the detection module signal.

[0046] The function of the cleaning control module includes controlling the flushing mechanism 3 to perform multiple flushing of the mold at a fixed time period. After each flushing operation, the flushing liquid is recovered, and the pH value of the recovered liquid is detected by the pH value detector 6. If the pH value is acidic, the next scheduled spraying is continued. If the pH value of the recovered cleaning agent matches the set value range, the flushing operation is stopped;

[0047] When the mold is rinsed in this embodiment, multiple rinse nozzles 302 perform multiple rinses of equal time periods. During each rinse, the liquid pump works at a set power, and the rinse nozzle 302 is fixedly opened for a set time. After each rinse, the pH value detector 6 detects the recovered liquid in the recovery tank 5, and determines whether the mold is rinsed clean by the detected pH value. If the pH value of the recovered liquid is alkaline, it means that the cleaning agent reacts with less oil and dirt, and the mold is nearly completely rinsed. When the pH value of the recovered liquid is detected to be the set value X, the rinse work can be stopped, and the value of X is greater than 7.

[0048] If the pH value of the recovered liquid is acidic, it means that the cleaning agent reacts with more oil and dirt, and the mold is not completely rinsed. At this time, the recovered liquid in the recovery tank 5 is completely discharged before the next stage of rinsing.

[0049] Optionally, when pH value detection is performed in this embodiment, the liquid level in the recovery tank 5 can be determined by a liquid level sensor, and then the electric push rod is controlled to work so that the pH value detection probe detects the liquid in the upper area of ​​the recovered liquid, ensuring that the pH value detection probe detects the liquid recovered by the final mold flushing;

[0050] In this embodiment, the pH value of each section of the flushing recovery liquid is detected during the flushing process, and whether it is flushed clean is determined based on the pH value. The cleaning time can be easily adjusted according to the amount of oil stains on the mold. The mold with more oil stains can be flushed for more sections, and the mold with less oil stains can be flushed for fewer sections. Compared with the existing equipment with fixed time period cleaning, it is easy to save water and clean completely.

[0051] In summary, this solution first uses the immersion cleaning tank 2 to weaken the oil stains on the entire mold, and then flushes the mold cavity, which is easy to ensure that the mold is fully cleaned. During the flushing process, the pH value of each flushing recovery liquid is detected, and whether it is flushed clean is determined based on the pH value. The cleaning time is easy to adjust according to the amount of oil stains on the mold, thereby improving the flushing efficiency and saving flushing water.

[0052] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
