[0038] like Figures 1 to 3As shown, the present invention provides a mold cleaning device, including an adjustment component 100, a spray component 200 and a bracket. The adjustment component 100 includes a first slide 110, a second slide 120 and a third slide 130. The first slide 110 can reciprocate along a first direction X, the second slide 120 is slidably connected to the first slide 110 along a second direction Y, and the third slide 130 is slidably connected to the second slide 120 along a third direction Z; the spray component 200 includes a mounting frame 210, a first nozzle 220 and a second nozzle 230. The first nozzle 220 can spray a neutralizer, and the second nozzle 230 can selectively spray clean water and / or The first nozzle 220 and the second nozzle 230 are both mounted on the mounting frame 210. The mounting frame 210 is mounted on the third slide 130 and can rotate relative to the third slide 130, so that the second nozzle 230 can be located at the bottom of the mold to spray airflow to the mold; the bracket includes a base and a clamp, an even number of clamps are provided, and are symmetrically arranged in the first direction X. The clamp is rotatably connected to the base, and the rotation axis is parallel to the first direction X. The clamp is used to fix the mold, and the first direction X, the second direction Y and the third direction Z are perpendicular to each other.

[0039] For example, when in use, a clamp is used to fix the mold, and the open side of the mold is set toward the second direction Y. The spray assembly 200 can achieve three-axis adjustment by adjusting the linkage between the first slide 110, the second slide 120 and the third slide 130 in the assembly 100. The spray assembly 200 is located on the second direction Y side of the mold, and the spraying directions of the first nozzle 220 and the second nozzle 230 are parallel to the second direction Y and toward the mold.

[0040] In the first step, the first nozzle 220 is activated to spray the neutralizer on the mold. The spraying component 200 can fully spray the mold as the adjustment component 100 moves; after the neutralizer spraying is completed, the second nozzle 230 is activated. The second nozzle 230 can spray clean water and / or air flow. First, the second nozzle 230 sprays clean water to rinse the neutralizer and other impurities on the mold. If the impurities are highly adhered to the mold, the second nozzle 230 is commanded to spray water and air flow at the same time. The high-pressure air flow can pressurize the water flow, giving it a stronger flushing ability. After the clean water flushing is completed, the fixture drives the mold to flip 90° so that the open side of the mold faces downward, and the adjustment frame rotates relative to the third slide 130 so that the second nozzle 230 is located below the mold, and the spraying direction is parallel to the third direction Z, facing the open side of the mold. The second nozzle 230 only sprays air flow to blow away the residual liquid on the mold, which can reduce water marks.

[0041] In this way, the mold cleaning device can complete the tasks of decontamination, cleaning, purging, etc. of the mold, reduce the participation of personnel, and has strong versatility for the mold, thereby improving the work quality and efficiency.

[0042] Optionally, the adjustment assembly 100 includes a base 140, a first driving member, a screw and a guide rail, the guide rail is laid along the first direction X, the first driving member is installed on the base 140, the first driving member is used to drive the screw to rotate, and the first slide 110 is slidingly connected to the guide rail and threadedly connected to the screw.

[0043] Specifically, two bases 140 are provided, which are spaced apart in the first direction X. The first driving member is installed on one of the bases 140. One end of the screw rod is connected to the output end of the first driving member, and the other end is rotatably connected to the other base 140. The first slide 110 is placed between the two bases 140.

[0044] In this way, the first slide 110 and the lead screw form a lead screw-slider model. When the first driving member drives the lead screw to rotate about its own axis, the first slide 110 cannot rotate with the lead screw due to contact with the guide rail, and thus moves along the axial direction of the lead screw, that is, the first direction X. The lead screw drive makes the movement accuracy of the first slide 110 relatively higher.

[0045] In other embodiments, a telescopic rod or other linear sliding mechanism may also be used.

[0046] The principle of relative movement between the second slide 120 and the first slide 110 is similar to the above content and will not be repeated here.

[0047] Optionally, the adjustment assembly 100 further includes a waterproof accordion cover 310 , which is sleeved outside the screw rod and the first driving member.

[0048] Specifically, the waterproof accordion cover 310 is mounted outside the screw rod and the first driving member. The two ends of the waterproof accordion cover 310 are respectively fixed to the two bases 140, always protecting the screw rod and the first driving member to prevent the screw rod and the first driving member from contacting moisture in the air, causing a short circuit.

[0049] Furthermore, a load-bearing accordion cover 320 is included. Generally, the load-bearing accordion cover 320 is mounted outside the waterproof accordion cover 310. The waterproof accordion cover 310 is usually a flexible member made of waterproof material, while the load-bearing accordion cover 320 is usually a rigid member made of stainless steel. One end of the load-bearing accordion cover 320 is fixed to one of the bases 140, and the other end of the load-bearing accordion cover 320 is fixed to the first slide 110. As the first slide 110 reciprocates along the first direction X, the load-bearing accordion cover 320 can be retracted or extended along the first direction X. The load-bearing accordion cover 320 is used to support staff to observe the mold cleaning process.

[0050] Optionally, the spray assembly 200 further includes a neutralizer supply pipeline and a first main solenoid valve. The first nozzle 220 is connected to the neutralizer supply pipeline through the first main solenoid valve. The first main solenoid valve is used to adjust the flow rate between the first nozzle 220 and the neutralizer supply pipeline.

[0051] Specifically, when the first main solenoid valve is closed, the neutralizer in the neutralizer supply pipeline is intercepted within the pipeline. When the first main solenoid valve is opened, the neutralizer in the neutralizer supply pipeline can flow through the first main solenoid valve to the first spray head 220. The opening degree of the first main solenoid valve can be changed to adjust the flow rate between the first spray head 220 and the neutralizer supply pipeline.

[0052] Optionally, the spray assembly 200 also includes a first auxiliary solenoid valve, and a plurality of first nozzles 220 are provided, some of which are first main nozzles and the other part are first auxiliary nozzles. When the first main solenoid valve is opened, the first main nozzle is connected to the neutralizer supply pipeline.

[0053] Specifically, the first main nozzle and the first auxiliary nozzle are respectively located in two branches, the first main solenoid valve is installed on the main road connecting the two branches, and the first auxiliary solenoid valve is installed on the branch where the first auxiliary nozzle is located, that is, when the first main solenoid valve is closed, regardless of whether the first auxiliary solenoid valve is in the open state, the neutralizer is intercepted in the main road, and the first main nozzle and the first auxiliary nozzle are both in an idle state; when the first main solenoid valve is opened, the neutralizer in the main road can flow to the two branches respectively, and the first main nozzle can spray the neutralizer. When the first auxiliary solenoid valve is in a closed state, the first auxiliary nozzle is in an idle state. When the first auxiliary solenoid valve is in an open state, the first auxiliary nozzle can also spray the neutralizer.

[0054] In this way, the number of the first nozzles 220 participating in the operation can be selected according to the operation requirements.

[0055] In other embodiments, the first main solenoid valve is arranged on the branch where the first main nozzle is located, that is, when the first main nozzle is needed to spray the neutralizer, the first main solenoid valve is opened, and when the first auxiliary nozzle is needed to spray the neutralizer, the first auxiliary solenoid valve is opened.

[0056] Optionally, the spray assembly 200 also includes a water supply pipe, an air supply pipe, a second main solenoid valve and a third main solenoid valve. The second nozzle 230 is connected to the water supply pipe and the air supply pipe, respectively.

[0057] Specifically, clean water is configured in the water supply pipe, and gas is configured in the air supply pipe. Both the water supply pipe and the air supply pipe are connected to the second nozzle 230. When the second nozzle 230 is required to spray only clean water, the second solenoid valve is opened and the third solenoid valve is closed; when the second nozzle 230 is required to spray high-pressure mist clean water, the second solenoid valve and the third solenoid valve are opened at the same time. At this time, the high-pressure airflow in the air supply pipe merges with the water flow in the water supply pipe to pressurize the water flow; when the second nozzle 230 is required to spray only airflow, the second solenoid valve is closed and the third solenoid valve is opened to perform air blowing and sweeping on the mold.

[0058] Optionally, the spray assembly 200 also includes a second auxiliary solenoid valve, and a plurality of second nozzles 230 are provided, some of which are second main nozzles and the other part are second auxiliary nozzles. When the second main solenoid valve is opened, the second main nozzle is connected to the water supply pipe.

[0059] Specifically, the second main nozzle and the second auxiliary nozzle are respectively located in two branches, the second main solenoid valve is installed on the main road connecting the two branches, and the second auxiliary solenoid valve is installed on the branch where the second auxiliary nozzle is located. That is, when the second main solenoid valve is closed, regardless of whether the second auxiliary solenoid valve is in the open state, the clean water is intercepted in the main road, and the second main nozzle and the second auxiliary nozzle are both in an idle state; when the second main solenoid valve is opened, the clean water in the main road can flow to the two branches respectively, and the second main nozzle can spray clean water. When the second auxiliary solenoid valve is in a closed state, the second auxiliary nozzle is in an idle state.
