[0010] In a preferred embodiment of the present invention, a side of the resistance-enhancing plate away from the jet plate is a downwardly bent structure for being extruded and matched with the jet plate.

[0011] In a preferred embodiment of the present invention, a reversing mechanism for switching the outlet direction of the jet pipe is further included.

[0015] The production process of coated sand casting based on the intelligent casting island has the following steps:

[0016] S1: Sand casting: The left and right sides of the casting mold are closed, the discharging machine slides forward, and then the sand casting machine is controlled to slide downward and dock with the upper side of the casting mold. The sand casting machine uses compressed air to inject the coated sand into the casting mold for heating and shaping;

[0017] S2: Cleaning: Before the casting mold is closed, the sliding plate is controlled to move forward and then backward to reset, so that the air jet pipe, the spray pipe and the wiping rod move back and forth. The air jet pipe sprays high-pressure gas to clean the residual coated sand in the casting mold, the spray pipe sprays the release agent into the casting mold for the next demolding, and the wiping rod moves back and forth to clean the stubborn coated sand remaining in the casting mold.

[0018] The invention has the following advantages: 1.

[0019] 2. When the jet pipe moves forward to preliminarily clean the casting mold, the jet plate moves backward to contact and rub against the resistance increasing plate, so that the spray pipe is connected to the through hole on the sliding plate. The release agent in the sprayer can be sprayed to the inner wall of the casting mold through the spray pipe, so that the sand mold can be separated from the casting mold and the residual coated sand can be reduced.

[0020] 3. When the jet plate drives the jet tube to move forward and backward, since the jet plate will slide on the sliding plate, the direction of the jet tube outlet can be adjusted by squeezing the outer end of the jet tube by pressing the rod so that the jet tube outlet faces the moving direction, so as to clean the corners in the casting mold and improve the cleaning effect.

[0021] 4. The closing plate rotates downward to fit the upper side of the casting mold to prevent the coated sand from splashing during sand filling. After the sand filling is completed, the closing plate rotates upward to reset and the remaining coated sand can be poured out.

[0022] 5. The wiping rod moves back and forth and rotates along the inner wall of the casting mold to clean the residual coated sand in the casting mold, further improving the cleaning effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Although the present invention may be described with respect to a particular application or industry, those skilled in the art will recognize the broader applicability of the present invention. Those of ordinary skill in the art will recognize that terms such as above, below, upward, downward, etc. are used to describe the drawings and do not represent limitations on the scope of the present invention as defined by the appended claims. Any numerical designations such as first or second are merely exemplary and are not intended to limit the scope of the present invention in any way.

[0035] Example 1: A coated sand casting production line based on an intelligent casting island, such as Figure 1 , Figure 2 and Figure 3As shown, it includes a mounting frame 1, a casting mold 11, a discharger 12, a sand casting machine 13, an electric push rod 2, a sliding plate 21, a fixed plate 22, a pressurizing machine 23, an air jet plate 24, an air jet pipe 25 and a first connecting pipe 26. The left and right parts of the front of the mounting frame 1 are fixedly connected to the casting mold 11, the upper rear part of the mounting frame 1 is slidably connected to the discharger 12, and the upper part of the discharger 12 is slidably connected to the sand casting machine 13. The rear part of the mounting frame 1 is fixedly connected to a left-right symmetrical fixed plate 22, the electric push rod 2 is fixedly connected between the left and right fixed plates 22, the telescopic end of the electric push rod 2 is fixedly connected to the sliding plate 21, the right rear part of the mounting frame 1 is fixedly connected to the pressurizing machine 23, the front part of the sliding plate 21 is slidably connected to the air jet plate 24, the left and right sides of the upper part of the air jet plate 24 are connected to five equidistantly distributed air jet pipes 25, the air jet pipe 25 is a corrugated pipe that can be shaped, and the first connecting pipe 26 is connected between the pressurizing machine 23 and the air jet plate 24.

[0036] When using the device, the staff controls the casting mold 11 on the left and right sides to close, and then controls the discharger 12 to slide forward. After the discharger 12 slides forward, the sand casting machine 13 is controlled to move downward to dock with the casting mold 11, and then the coated sand is injected into the casting mold 11 by compressed air through the sand casting machine 13 for heating and shaping. After the sand mold is shaped, the staff controls the sand casting machine 13 to move upward and reset, and then controls the discharger 12 to slide backward, and finally controls the casting mold 11 to open. At this time, the staff can take out the sand mold, and then control the electric push rod 2 to extend and then shorten. The extension and shortening of the electric push rod 2 drives the sliding plate 21 to move forward and then move backward. The sliding plate 21 moves forward and backward, driving the jet plate 24 to drive the jet pipe 25 to move forward and backward. When the jet pipe 25 moves forward and backward, the pressurizer 23 can convey high-pressure gas to the jet plate 24 through the jet pipe 25. When the jet pipe 25 moves forward and backward, the jet can spray to clean the inner wall of the casting mold 11 to avoid the residual coated sand in the casting mold 11 affecting the quality of the sand mold for subsequent casting.

[0037] Embodiment 2: Based on embodiment 1, Figure 1 , Figure 4 and Figure 5As shown, it also includes a spraying mechanism for spraying a release agent, the spraying mechanism includes a sprayer 3, a second connecting pipe 31, a spraying pipe 32, a guide plate 33, a resistance increasing plate 34 and a first spring 35. The sprayer 3 is fixedly connected to the left rear of the mounting frame 1, the sliding plate 21 is a hollow structure, the second connecting pipe 31 is connected between the sprayer 3 and the sliding plate 21, the left and right parts of the upper part of the jet plate 24 are connected to four equidistantly distributed spraying pipes 32, the left and right sides of the front part of the sliding plate 21 are provided with four equidistantly distributed through holes for communicating with the spraying pipes 32, the middle position of the front part of the mounting frame 1 is fixedly connected to the guide plate 33, the resistance increasing plate 34 is slidably connected to the guide plate 33, the resistance increasing plate 34 is in extrusion contact with the jet plate 24, the rear part of the resistance increasing plate 34 is a downward bending structure for extrusion cooperation with the jet plate 24, and two first springs 35 are connected between the resistance increasing plate 34 and the guide plate 33.

[0038] By setting up a spraying mechanism, a release agent can be sprayed into the casting mold 11 so that the sand mold can be separated from the casting mold 11 and the residual coated sand can be reduced. The specific operation is as follows: when the jet plate 24 moves forward, the spraying tube 32 also moves forward. When the jet plate 24 moves forward, it will contact the resistance increasing plate 34, and then squeeze the resistance increasing plate 34 to slide downward, and the first spring 35 will be deformed. At this time, the spraying tube 32 is not connected with the through hole opened at the front of the sliding plate 21, so when moving forward, the spraying tube 32 will not spray the release agent. When the jet pipe 25 moves forward to preliminarily clean the casting mold 11, the sliding plate 21 drives the jet plate 24 to move backward. Under the action of the resistance increasing plate 34, the jet plate 24 will slide forward on the sliding plate 21 due to friction, so that the spray pipe 32 is connected to the through hole on the sliding plate 21. At this time, the release agent in the sprayer 3 can enter the sliding plate 21 through the second connecting pipe 31, and then be sprayed to the inner wall of the casting mold 11 through the spray pipe 32, so that the sand mold can be separated from the casting mold 11, reducing the residual coated sand.

[0039] like Figure 1 and Figure 6 As shown, a reversing mechanism for switching the outlet direction of the jet pipe 25 is also included, and the reversing mechanism includes a positioning rod 4 and a pressing rod 41. The left and right sides of the front of the sliding plate 21 are fixedly connected with front-to-back symmetrical positioning rods 4, and the sides of the front-to-back symmetrical positioning rods 4 close to each other are fixedly connected with five equidistantly distributed pressing rods 41, and the pressing rods 41 are in contact with the adjacent jet pipe 25.

[0040] By setting a reversing mechanism, the direction of the outlet of the jet pipe 25 can be adjusted so that the outlet of the jet pipe 25 faces the moving direction, so that the corners in the casting mold 11 can be cleaned and the cleaning effect can be improved. The specific operation is as follows: when the sliding plate 21 drives the jet plate 24 to move forward, the jet plate 24 will be squeezed and moved backward by the resistance increasing plate 34, thereby driving the inner end of the jet pipe 25 to move backward, and the outer end of the jet pipe 25 will be squeezed and swung forward by the pressing rod 41, so that when the jet pipe 25 moves forward, the outlet of the jet pipe 25 faces forward, and when the sliding plate 21 drives the jet plate 24 to move backward, the jet plate 24 will be squeezed and moved forward by the resistance increasing plate 34 again, thereby causing the inner end of the jet pipe 25 to move forward, and the outer end of the jet pipe 25 will be squeezed and swung backward by the pressing rod 41, at this time, the outlet of the jet pipe 25 moves backward and faces backward, so that the direction of the outlet of the jet pipe 25 can be adjusted so that the outlet of the jet pipe 25 faces the moving direction, so that the corners in the casting mold 11 can be cleaned and the cleaning effect can be improved.

[0041] like Figure 1 , Figure 7 and Figure 8 As shown, it also includes a blocking mechanism for blocking the splashing of coated sand, the blocking mechanism includes an L-shaped rod 5, a closing plate 51, a torsion spring 52, a pushing block 53, an extrusion block 54, a connecting rod 55, a material blocking plate 56 and a second spring 57. A left-right symmetrical L-shaped rod 5 is fixedly connected to the upper and middle part of the mounting frame 1, a closing plate 51 is rotatably connected between the left and right L-shaped rods 5, a torsion spring 52 is connected between the closing plate 51 and the L-shaped rod 5, a pushing block 53 is fixedly connected to the lower side of the sand casting machine 13, the pushing block 53 is extruded and matched with the closing plate 51, the left and right sides of the pushing block 53 are fixedly connected with the extrusion blocks 54, the left and right sides of the closing plate 51 are fixedly connected with two connecting rods 55, a material blocking plate 56 is slidably connected between the two connecting rods 55 on the same side, the material blocking plate 56 is L-shaped, the front part of the extrusion block 54 is inclined, the material blocking plate 56 is extruded and matched with the adjacent extrusion block 54, and a second spring 57 is connected between the material blocking plate 56 and the adjacent connecting rod 55.

[0042] By setting a blocking mechanism, the upper side can be blocked when the sand casting machine 13 is pouring sand into the casting mold 11 to prevent the coated sand from splashing. The specific operation is as follows: when the discharge machine 12 slides forward, the sand casting machine 13 drives the pushing block 53 to move forward, and the pushing block 53 moves forward to squeeze the closing plate 51 to rotate downward, and the torsion spring 52 is deformed. While the pushing block 53 moves forward, it also drives the squeezing block 54 to move forward. The squeezing block 54 moves forward to squeeze the blocking plate 56 to slide back and open, and the second spring 57 is deformed. When the sand casting machine 13 moves downward, the pushing block 53 also moves downward, and the pushing block 53 moves downward to squeeze the closing plate 51 to rotate downward again, so that the closing plate 51 fits the upper side of the casting mold 11 At this time, the coated sand sprayed by the sand casting machine 13 can enter the casting mold 11 through the hole groove in the middle of the closing plate 51. After a certain amount of coated sand is poured in, the sand casting machine 13 moves upward and resets, and then moves backward with the discharging machine 12, and the pushing block 53 and the extrusion block 54 also move backward. At this time, under the action of the third spring 61, the baffle plate 56 slides toward each other and resets. Under the action of the torsion spring 52, the closing plate 51 rotates upward and resets. At this time, the coated sand remaining on the closing plate 51 can be poured backward along the inclined closing plate 51. In this way, the upper side of the casting mold 11 can be blocked during sand filling to prevent the coated sand from splashing. After sand filling, the remaining coated sand can be poured backward.

[0043] like Figure 1 , Fig. 9 and Fig.10 As shown, it also includes a cleaning mechanism for cleaning residual coated sand in the casting mold 11, the cleaning mechanism includes an L-shaped plate 6, a third spring 61, a drive motor 62 and a wiping rod 63, the front part of the sliding plate 21 is slidingly connected with a left-right symmetrical L-shaped plate 6, the third spring 61 is connected between the L-shaped plate 6 and the sliding plate 21, the drive motor 62 is fixedly connected to the L-shaped plate 6, and the wiping rod 63 is fixedly connected to the output shaft of the drive motor 62.

[0044] By setting up a cleaning mechanism, the residual coated sand in the casting mold 11 can be cleaned, and the cleaning effect can be further improved. The specific operations are as follows: when the sliding plate 21 moves forward and backward, it will also drive the L-shaped plate 6, the driving motor 62 and the wiping rod 63 to move forward and backward together. When the driving motor 62 moves forward and backward, it will drive the wiping rod 63 to rotate. At the same time, under the action of the third spring 61, the wiping rod 63 can move and clean against the inner wall of the casting mold 11, thereby further improving the cleaning effect.

[0045] Example 3: Based on Examples 1 and 2, a coated sand casting production process based on an intelligent casting island has the following steps:

[0046] S1: Sand casting: The left and right sides of the casting mold 11 are closed, the discharge machine 12 slides forward, and then the sand casting machine 13 is controlled to slide downward and dock with the upper side of the casting mold 11, and the coated sand is injected into the casting mold 11 by compressed air through the sand casting machine 13 to heat and shape;

[0047] S2: Cleaning: Before the casting mold 11 is closed, the sliding plate 21 is controlled to move forward and then backward to reset, so that the air injection pipe 25, the spray pipe 32 and the wiping rod 63 can move back and forth. The air injection pipe 25 sprays high-pressure gas to clean the residual coated sand in the casting mold 11, and the spray pipe 32 sprays the release agent into the casting mold 11 for the next demolding, while the wiping rod 63 moves back and forth to clean the stubborn coated sand remaining in the casting mold 11;
