Description

Technical Field

[0001] This utility model relates to the field of casting mold cleaning, specifically to a mold cleaning machine. Background Technology

[0002] Molds are generally composed of multiple parts, so mold production typically involves processing each part independently. After various processing steps, it's difficult to avoid iron powder or other contaminants remaining on the surface and inside the holes of individual mold parts. Due to the nature of these contaminants, they tend to adhere quite firmly to the inner walls of holes, making them very difficult to remove using conventional cleaning methods. If the contaminants are not properly cleaned, assembling the individual parts into a mold will result in poor fit between the ejector pins and holes, and in severe cases, may even lead to breakage of the ejector pins, ultimately damaging the mold.

[0003] Currently, the cleaning methods for individual mold workpieces involve using an air gun to blow air onto the surface and inside deep holes of the mold workpiece, as well as using a brush. However, existing cleaning methods are not only time-consuming and labor-intensive, but also difficult to remove dirt completely. In addition, the dirt removed during the cleaning process is splashed everywhere by the high-speed airflow and the brushing motion. Utility Model Content

[0080] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example

[0081] like Figures 1 to 15 As shown, a mold cleaning machine includes:

[0082] The cleaning chamber 1 is equipped with an openable cover 14, which closes the cleaning chamber when the cover 14 is closed.

[0083] A planar moving unit is installed at the top of the cleaning chamber 1;

[0084] The oscillation control unit is set on the planar moving unit and controls the moving end of the planar moving unit to perform oscillation displacement around the mold to be cleaned placed in the cleaning chamber.

[0085] The cleaning unit is located on the moving end of the planar moving unit, and its cleaning nozzle points to the lower part of the cleaning chamber 1 to spray and clean the mold to be cleaned placed in the cleaning chamber.

[0086] The enclosed cleaning chamber 1 confines the cleaning water and dirt generated during the cleaning process within a limited space, preventing pollution of the factory environment and facilitating centralized treatment of wastewater after cleaning. The planar displacement unit effectively cleans various areas of the mold surface within the cleaning chamber 1. The nozzles on the cleaning unit allow adjustment of the spray angle and intensity, ensuring thorough cleaning of all surfaces of the mold workpiece 6. The revolving control unit slightly alters the cleaning unit's spherical motion around the mold workpiece 6, creating an angle between the water jets from the nozzles and the cleaning areas on the mold workpiece 6. This improves the cleaning effect and ensures that deep holes or concave areas on the mold workpiece 6 are reached as thoroughly as possible for a more complete cleaning.

[0087] In this embodiment, the cleaning chamber 1 includes:

[0088] The cleaning rack 11 has a frame structure and is rectangular in shape; the planar moving unit is located on the upper part of the cleaning rack 11.

[0089] A base plate 12 is disposed on the inner side of the bottom of the cleaning rack 11 and is used to accommodate the mold to be cleaned; the base plate 12 is provided with a liquid outlet.

[0090] Four side panels 13 are set on the four outer sides of the cleaning rack 11, one of which is made of transparent or semi-transparent material;

[0091] Two cover plates 14 are symmetrically and openable on the top outer side of the cleaning rack 11; the cover plates 14, four side plates 13 and bottom plate 12 form a closable cuboid.

[0092] The transparent side panel 13 allows observation of the cleaning process of the mold workpiece 6, and the cover plate 14 facilitates the removal of the cleaned mold workpiece 6. This design also helps to ensure that the wastewater after cleaning does not leak out as much as possible.

[0093] In this embodiment, the planar moving unit includes:

[0094] The left-right movable component is located on the upper part of the cleaning rack 11;

[0095] The forward and backward moving component is disposed on the moving end of the left and right moving component; the circumferential control unit is disposed on the forward and backward moving component.

[0096] In this embodiment, the left and right moving component includes:

[0097] The first crossbar 211 and the second crossbar 212 are respectively arranged directly below the first crossbeam 111 and the second crossbeam 112 on the upper part of the cleaning rack 11; the axes of the first crossbar 211, the second crossbar 212, the first crossbeam 111 and the second crossbeam 112 are parallel; a first gap 217 is left between the first crossbar 211 and the first crossbeam 111; a second gap 218 is left between the second crossbar 212 and the second crossbeam 112;

[0098] The first baffle 213, the second baffle 214, the third baffle 215, and the fourth baffle 216 are respectively disposed on the inner side of the first crossbar 211, the second crossbar 212, the first crossbeam 111, and the second crossbeam 112. The upper end face of the first baffle 213 is parallel to the axis of the first crossbar 211 and extends beyond the upper end face of the first crossbar 211. The upper end face of the second baffle 214 is parallel to the axis of the second crossbar 212 and extends beyond the upper end face of the second crossbar 212.

The lower end face of the fourth baffle 216 is parallel to the axis of the second crossbeam 112 and extends beyond the lower end face of the second crossbeam 112.

[0099] The first slider 219 and the second slider 220 are respectively disposed in the first gap 217 and the second gap 218; the upper surface of the first slider 219 contacts the lower surface of the first crossbeam 111, the lower surface contacts the upper surface of the first crossbeam 111, and the inner side contacts the outer side of the first baffle 213 and the third baffle 215; the upper surface of the second slider 220 contacts the lower surface of the second crossbeam 112, the lower surface contacts the upper surface of the second crossbeam 112, and the inner side contacts the outer side of the second baffle 214 and the fourth baffle 216.

[0100] Two connecting rods 221 are respectively connected to the first slider 219 and the second slider 220; the forward and backward moving assembly is disposed on the two connecting rods 221;

[0101] The left and right controllers are connected to the two connecting rods 221 to control the displacement of the first slider 219 and the second slider 220.

[0102] The sliding groove is formed by the first gap 217 and the second gap 218, and the first slider 219 and the second slider 220 are fixedly connected and restricted by the connecting rod 221. Combined with the setting of four baffles, two back-to-back locking grooves with strip grooves are formed as a whole, thus realizing the sliding guidance and limiting of the first slider 219 and the second slider 220.

[0103] In this embodiment, the left and right controllers include:

[0104] Four guide rods 2221 are rotatably mounted on the cleaning rack 11 in a rectangular shape; each guide rod 2221 is equipped with a grooved guide wheel 22211.

[0105] The control lever 2222 is rotatably mounted on the lower part of the cleaning rack 11, parallel to the guide lever 2221; the control lever 2222 is provided with a winding wheel 22221 with a spiral groove;

[0106] The left and right handwheels 2224 are coaxially connected to one end of the control lever 2222;

[0107] The control line 2223 is connected at one end to a connecting rod 221, and at the other end, after passing over the guide wheel 22211 of the four guide rods 2221 and the winding wheel 22221 of the control rod 2222, it is connected to another connecting rod 221.

[0108] By rotating the left and right handwheels 2224, the connecting rod 221 is pulled, thereby controlling the sliding of the first slider 219 and the second slider 220, and ultimately achieving control of left and right displacement.

[0109] In this embodiment, the forward and backward moving component includes:

[0110] The lead screw 231 has its head end rotatably connected to the first slider 219 and its tail end rotatably connected to the second slider 220.

[0111] The movable part is fitted onto the lead screw 231; the cleaning unit is mounted on the movable part.

[0112] The front and rear handwheels 233 are connected to the head end of the lead screw 231;

[0113] Four auxiliary components are arranged on both sides of the moving part, directly opposite the two connecting rods 221; one end of each auxiliary component is slidably connected to the connecting rod 221, and the other end is flexibly supported and connected to the moving part; the oscillation control unit is connected to the moving part.

[0114] The auxiliary component prevents the moving part from rotating around the lead screw 231 and forces the moving part to displace along the axis of the lead screw 231.

[0115] In this embodiment, the auxiliary component includes:

[0116] Tension spring 2341, one end of which is connected to the moving part;

[0117] The snap-fit ​​slider 2342 is set on the outer surface of the connecting rod 221 and is connected to the other end of the tension spring 2341.

[0118] In this embodiment, the movable part includes an upper block 2321 and a lower block 2322 that can be fixed together as a single unit; the lower surface of the upper block 2321 and the upper surface of the lower block 2322 are provided with threaded semi-circular tubular grooves 2323 that match the lead screw 231; when the upper block 2321 and the lower block 2322 are fixed together as a single unit, the lead screw 231 is threadedly connected to the upper block 2321 and the lower block 2322; the cleaning unit is disposed on the lower surface of the lower block 2322.

[0119] The upper block 2321 is provided with a through hole 23211 with internal threads, which is directly opposite the threaded semi-circular tubular groove 2323 on its lower surface;

[0120] The first slider 219 has a wide fit with the head end of the lead screw 231, and the tail end of the lead screw 231 is limited in its rotation with the second slider 220; the rotation control unit includes:

[0121] Butterfly screw 31, threaded connection inside through hole 23211;

[0122] Two pull ropes 32, one end of each is connected to the two lugs of the butterfly screw 31, and the other end of each passes through the cleaning chamber 1 and is located on the outside of the cleaning chamber 1.

[0123] The rotation of the butterfly screw 31 is controlled by two pull ropes 32, thereby controlling and releasing the restriction of the butterfly screw 31 on the rotation of the lead screw 231, thus realizing the control of the moving part and the lead screw 231 to be fixed together or separated. When the moving part and the lead screw 231 are integrated, the nozzle of the cleaning unit located on the moving part can be controlled to move around the mold workpiece 6 to be cleaned by swinging the front and rear handwheels 233.

[0124] The wide-fit design employs a large hole 2191 on the first slider 219, allowing the head end of the lead screw 231 to pass through the hole 2191. The width, height, or diameter of the hole is much larger than the diameter of the head end of the lead screw 231, providing sufficient displacement space for the head end of the lead screw 231. The end of the lead screw 231 is designed as a universal ball 2311. The second slider 220 uses an upper and lower clamping plate structure to clamp and limit the end of the lead screw 231. The clamping space is a funnel-shaped cavity that allows the universal ball 2311 to rotate in any direction and allows for displacement of the lead screw 231, thus ensuring that the end of the lead screw 231 can rotate at a certain angle without interfering with the second slider.

[0125] In this embodiment, the lower block 2322 is provided with several water channels;

[0126] The cleaning unit includes:

[0129] The high-pressure water pump 44 has its outlet connected to the inlet of the water collector 42.

[0130] In this example, a filter unit is also included, which is located directly below the cleaning chamber 1; the filter unit includes:

[0131] The filter chamber 51 is located directly below the cleaning chamber 1;

[0132] Two filter partitions 52 are set inside the filter chamber 51, dividing the filter chamber 51 into three independent receiving chambers; the upper part of the filter partition 52 is provided with filter holes 521; the cleaning chamber 1 is connected to one of the receiving chambers by a connecting pipe 53 with a filter screen.

[0133] Impurities are filtered and separated through the connecting pipe 53, and then after sedimentation in the containment chamber, the upper layer enters another containment chamber through the filter hole 521. This achieves sedimentation filtration, reduces wastewater treatment costs, and the sedimented and filtered water can be reused for cleaning.

[0134] In this embodiment, the mold cleaning machine works as follows:

[0135] First, rotate the front and rear handwheels 233 and the left and right handwheels 2224 to move the moving part to one side or corner of the cleaning chamber 1. Select and install the appropriate high-pressure nozzle 41 according to the surface condition of the mold workpiece 6 to be cleaned, and adjust the angle of the high-pressure nozzle 41. Then, open the cover plate 14, place the mold workpiece 6 to be cleaned into the cleaning chamber 1, and finally close the cover plate 14.

[0136] The second step is to open the control valve 43 corresponding to the high-pressure nozzle 41, and then start the high-pressure water pump 44. High-pressure cleaning water is sprayed and rinsed on the surface of the mold workpiece 6 through the high-pressure nozzle 41.

[0137] The third step is to clean the area that has been rinsed by the high-pressure nozzle 41, and then change the area sprayed by the high-pressure nozzle 41 by turning the front and rear handwheels 233 and the left and right handwheels 2224.

[0138] During the above cleaning process, if there is a concave surface or deep hole in the area, or if impact rinsing is required, pull a rope 32 to make the butterfly screw 31 abut against the lead screw 231, and then hold the front and rear handwheels 233 and swing them up, down and left and right to make the high-pressure nozzle 41 impact the surface of the mold workpiece 6.

[0139] During the cleaning process, the wastewater after cleaning flows into the filter chamber 51 through the connecting pipe 53.

[0140] After cleaning is complete, turn off the high-pressure water pump 44, then turn the front and rear handwheels 233 and the left and right handwheels 2224 to move the moving part to one side or a corner of the cleaning chamber 1. Then open the cover plate 14 and take out the cleaned mold workpiece 6.

[0141] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of this technical solution, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
