Description

Technical Field

[0001] The invention relates to the technical field of environmentally friendly metal production, and in particular to intelligent integrated equipment for producing environmentally friendly metal castings. Background Art

[0002] Environmentally friendly metal castings refer to metal castings that minimize negative impacts on the environment during the design, manufacturing, use and disposal processes. For example, metal manhole covers are common in life. When producing metal manhole covers, a molding machine is needed to die-cast the molding sand into a manhole cover mold with a gate before subsequent casting work is carried out.

[0003] In the process of producing manhole cover castings, since most existing molding machines use longitudinal hydraulic methods to extrude the molding sand, it is impossible to perform targeted extrusion on the gate position. When the gate rod is separated from the casting gate, longitudinal friction is generated between the gate rod and the casting gate, and the casting gate collapses, resulting in the inability to carry out subsequent casting work normally, and the production quality of the manhole cover casting is difficult to guarantee.

[0004] Furthermore, in the process of using the existing molding machine to produce manhole cover castings, since the casting mold has many lines and a large contact area with the molding sand, the mold after molding fits tightly against the inner wall of the casting mold. During separation, the molding sand in the inner cavity of the casting mold adheres to the casting mold, causing pits in the inner cavity of the casting mold, resulting in abnormal protrusions in the subsequently cast manhole covers, which increases the workload of subsequent polishing.

[0041] like Figure 5 As shown, a circular arc groove 10202 is provided at the lower outer side of the extrusion plate 102 .

[0042] Also includes a support block 7; Figure 5 As shown, a support block 7 is fixedly connected to the lower side of all expansion plates 5; an extrusion portion 7001 is provided in the middle of the upper side of the support block 7; the extrusion portion 7001 is provided in a truncated cone shape; and the parts of the support block 7 except the extrusion portion 7001 are all made of elastic deformation material.

[0043] The present invention expands the mold gate in the horizontal direction through the expansion plate 5, which solves the problem that only the longitudinal extrusion force is generated on the molding sand during the production of the mold, and the gate position cannot be squeezed in a targeted manner, resulting in greater difficulty in core pulling of the longitudinal gate and easy collapse of the gate. The specific process is as follows:

[0044] When producing the manhole cover casting, the electric slider 109 is controlled to drive the fourth driving member 110 to slide forward on the slide rail 108, driving the mold 104 to move to the bottom of the mold box 101, and then the telescopic end of the fourth driving member 110 is controlled to extend, so that the mold 104 is lowered to the upper side of the limiting portion 1002 and keeps a distance from the limiting portion 1002, and then the telescopic ends of the first driving member 105 and the second driving member 106 are controlled to extend, driving the mold box 101 and the extrusion plate 102 to descend together, so that the lower side of the molding part 10101 is attached to the upper side of the mold 104, and at the same time, the two blocking plates 103 are lowered to between the two limiting portions 1002. At this time, the two blocking plates 103 and The two limiting parts 1002 are combined into a rectangular frame on the lower side of the mold 104. At this time, the first electrically controlled valve plate 1001 and the second electrically controlled valve plate 10201 are controlled to open, and then the external feeding equipment is controlled to transfer the molding sand through the transmission pipe 2 to the molding part 10101 and the rectangular frame composed of the sealing plate 103 and the limiting part 1002. When the molding sand is transferred, the telescopic ends of the second driving member 106 and the fourth driving member 110 are controlled to continue to extend, driving the extrusion plate 102 and the mold 104 to descend, and the molding sand on the upper side of the mold 104 is compacted by pressing down the extrusion plate 102, and the molding sand on the lower side of the mold 104 is compacted by descending the mold 104.

[0045] When the extrusion plate 102 moves downward, the support block 7 contacts with the upper side of the mold 104. When the molding sand is pressed, the extrusion plate 102 drives the top block 3 to move downward continuously. The expansion plate 5 is squeezed toward the outside of the top block 3 by moving the inverted truncated cone-shaped top block 3 downward, and the blocking ring 4 is squeezed and the elastic rope 6 is stretched to expand the casting gate in the horizontal direction, thereby applying a horizontal extrusion force to the casting gate, which is beneficial to enhance the structural strength of the casting gate and prevent the casting gate from collapsing when the subsequent expansion plate 5 is separated from the casting gate, thereby enhancing the structural strength of the casting gate. When the expansion plate 5 expands toward the outside of the top block 3, the force-bearing part 5001 moves upward in the slide groove 3001 compared to the top block 3, and the upper side of all the expansion plates 5 is blocked by the blocking ring 4 to prevent the molding sand from entering between the expansion plates 5. At the same time, since the connection between the force-bearing part 5001 and the elastic rope 6 and the expansion plate 5 is as shown in the figure Figure 6 In the state shown, when the expansion plates 5 are squeezed toward the outside of the top block 3, all the expansion plates 5 are always in close contact with each other, which is beneficial to prevent the molding sand from getting stuck between two adjacent expansion plates 5, prevent the expansion plates 5 from deforming and causing damage to the casting gate, and further enhance the structural strength of the casting gate.

[0046] When the top block 3 squeezes the expansion support plate 5 toward the outside of the expansion support plate 5, the expansion support plate 5 is simultaneously subjected to the downward pressure of the top block 3, and all the expansion support plates 5 squeeze downward the outside of the support block 7. At this time, the extrusion portion 7001 moves upward compared to the expansion support plate 5. The extrusion portion 7001 is set in a truncated cone shape to squeeze the lower part of all the expansion support plates 5 toward the outside of the support block 7, so that the lower part of the expansion support plate 5 applies a horizontal extrusion force to the lower part of the casting gate, thereby further enhancing the structural strength of the casting gate.

[0047] The present invention avoids friction with the casting mold when the inverted rectangular funnel-shaped forming part 10101 is separated from the casting mold, thereby solving the problem that the casting mold is damaged due to friction when the casting mold is separated, and the strength of the casting mold structure is reduced. The specific working process is as follows:

[0048] After the molding sand is compacted into a mold, the second driving member 106 is controlled to drive the extrusion plate 102 to rise to the upper side of the air pipe 201, and the external air pump is controlled to make the air pipe 201 evacuate the molding part 10101, so that the mold on the upper side of the mold 104 is adsorbed into the molding part 10101. At the same time, the molding sand is intercepted by the interception net 202 to prevent scattered molding sand from clogging the air pipe 201. At this time, the telescopic end of the third driving member 107 is controlled to retract, driving the two blocking plates 103 to rotate toward the front and rear sides of the molding box 101. , so that the mold between the blocking plate 103 and the limiting part 1002 is separated, so as to prevent the subsequent blocking plate 103 from rubbing against the side wall of the mold when rising, and to avoid damage to the mold structure, and then control the first driving member 105 and the second driving member 106 to drive the mold box 101, the extrusion plate 102 and the blocking plate 103 to rise together, so that the mold on the upper side of the mold 104 is separated from the mold 104, and the blocking plate 103 is separated from the mold on the lower side of the mold 104, and the fourth driving member 110 is controlled to drive the mold 104 to rise, so that the mold 104 The mold 104 is separated from the lower side of the mold 104, and then the electric slider 109 is controlled to drive the fourth driving member 110 and the mold 104 to slide backward on the slide rail 108, and the mold 104 is removed from between the two molds. After the mold 104 is removed, the staff applies adhesive to the upper side of the mold between the limiting parts 1002, and then controls the first driving member 105 and the second driving member 106 to drive the mold box 101 and the extrusion plate 102 to descend together, and the mold in the molding part 10101 is placed on the limiting part 1002. The upper side of the casting mold between them is used to make the two castings fit together. At this time, the external air pump stops suction, and controls the first driving member 105 and the second driving member 106 to drive the mold box 101 and the extrusion plate 102 to rise together, so that the molding part 10101 is separated from the casting. Since the molding part 10101 is arranged in an inverted rectangular funnel shape, the molding part 10101 does not rub against the side wall of the casting when it is separated from the casting, thereby preventing the casting and the molding part 10101 from rubbing against each other, avoiding damage to the casting due to friction, and ensuring the structural strength of the produced casting.

[0049] When the mold box 101 and the extrusion plate 102 rise together and separate from the mold, the top block 3 rises together with the extrusion plate 102, and all the expansion plates 5 that are squeezed outward by the top block 3 are retracted toward the middle of the top block 3 under the rebound action of the blocking ring 4 and the elastic rope 6, so that the expansion plates 5 are separated from the side walls of the gate, and the gap between the expansion plates 5 and the side walls of the gate is increased. While enhancing the strength of the casting gate, it prevents the expansion plates 5 from rubbing against the casting gate when rising, avoids the falling of the molding sand at the casting gate, and further ensures the structural strength of the casting gate.

[0050] The present invention guides the airflow through the arc groove 10202 to blow off the molding sand adhered to the extrusion plate 102 and the molding part 10101, thereby solving the problem that the residual molding sand in the existing casting causes pits in the subsequent casting and reduces the strength of the casting structure. The specific working process is as follows:

[0051] When the upper and lower casting molds are completely fitted together, the telescopic end of the fifth driving member 302 is controlled to extend, driving the push plate 301 to move forward, pushing the casting mold toward the front side of the molding machine 1, and transmitting the casting mold to the casting process through the transmission equipment for casting. At this time, the external air pump is controlled to make the air pipe 201 blow air into the molding part 10101, and the molding sand adhered to the lower side of the extrusion plate 102 is blown off by the air flow. Then the second driving member 106 is controlled to drive the extrusion plate 102 to descend. When the circular arc groove 10202 moves down to below the air pipe 201, the air flow blown out of the air pipe 201 is guided to the molding part 10101 through the circular arc groove 10202, and the molding sand adhered to the molding part 10101 is blown off to between the two limiting parts 1002 by the air flow, so as to prevent the molding sand from adhering to the lower side of the extrusion plate 102 and the molding part 10101, and to avoid the accumulation of molding sand causing pits in the subsequent casting mold, thereby further ensuring the structural strength of the produced casting mold.

[0052] At this time, the second driving member 106 is controlled to drive the extrusion plate 102 to continue to descend, so that the ventilation cavity 10203 is horizontally aligned with the air pipe 201, and the air flow blown out of the air pipe 201 is guided to the sealing ring 4 through the ventilation cavity 10203, and then blown downwardly by the sealing ring 4 toward the outside of the expansion plate 5, so as to blow off the molding sand adhered to the outside of the expansion plate 5, and prevent the molding sand from accumulating on the outside of the expansion plate 5, which may cause the molding sand to wear the casting gate when the expansion plate 5 is separated from the casting gate, and avoid damage to the casting gate so that the subsequent casting work cannot be carried out normally, thereby further ensuring the structural strength of the produced casting. Subsequently, the fifth driving member 302 is controlled to drive the push plate 301 to move backward, and the molding sand between the limiting parts 1002 is scraped into the recovery tank 1003, and falls into the molding sand collection equipment through the recovery tank 1003 for collection, so as to prepare for the next casting work.

[0058] The power assembly includes a second motor 407 ; the second motor 407 is fixedly connected to the upper rear portion of the push plate 301 ; and the output end of the second motor 407 is fixedly connected to the second cleaning brush 406 .

[0059] The present invention uses the first cleaning brush 401 and the second cleaning brush 406 to clean the residual molding sand on the upper side and the lower side of the mold 104, thereby solving the problem that the mold cavity produced has pits due to the molding sand adhering to the mold 104, which in turn causes the surface of the metal casting to have abnormal protrusions, increasing the subsequent grinding work. The specific process is as follows:

[0060] When controlling the mold 104 to move forward and prepare for die-casting again, the mold 104 pushes the baffle 402 forward so that the lower part of the baffle 402 contacts the upper side of the mold 104. At this time, the baffle 402 is in an inclined state, and is viewed from right to left. At this time, the first motor 404 is controlled to drive the first cleaning brush 401 to rotate counterclockwise, and the molding sand adhered to the upper side of the mold 104 is brushed toward the back side of the mold 104, and the upper side of the mold 104 is cleaned to prevent the produced casting cavity from having pits inside, and to avoid abnormal protrusions on the surface of the subsequently cast metal castings, thereby ensuring the quality of the subsequently cast metal castings. During the rotation of the first cleaning brush 401, the molding sand brushed off is blocked by the baffle 402, and falls into the upturned portion 40201 for collection. When the mold 104 moves to the bottom of the mold box 101. At this time, the rear of the mold 104 is close to the rear side of the baffle 402, and the baffle 402 is driven by the magnet 403 to be adsorbed to the rear of the mold 104, so that the upturned part 40201 tilts downward, and the collected molding sand is poured into the recovery tank 1003 below, thereby improving the molding sand collection effect.

[0061] When the mold 104 moves forward to the bottom of the molding box 101, the push plate 301 is controlled to move backward for resetting. During the resetting process of the push plate 301, the second motor 407 is controlled to drive the second cleaning brush 406 to rotate clockwise, based on the view from right to left, to brush the molding sand adhered to the lower side of the mold 104 toward the rear side and make it fall between the two limit parts 1002. The molding sand that falls between the two limit parts 1002 is scraped backward by resetting the push plate 301. In this process, the molding sand brushed backward by the second cleaning brush 406 is blocked by the baffle plate 405, and is made to fall into the recovery tank 1003 for collection, thereby further ensuring the quality of the metal castings subsequently cast.

[0062] Example 3

[0063] On the basis of Examples 1 and 2, Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, a vibration system is also included, which includes a protrusion 501, a translation component and a knocking rod 502; a plurality of left-right symmetrical protrusions 501 are fixedly connected to the mold 104; a translation component is connected to the baffle 405; two fixed plates are connected to the translation component; each fixed plate is rotatably connected to a knocking rod 502 through a torsion spring; the fixed plate and the knocking rod 502 are driven to move by the translation component.

[0064] The translation assembly includes a sixth driving member 503 ; two left-right symmetrical sixth driving members 503 are fixedly connected to the baffle plate 405 ; and the telescopic end of each sixth driving member 503 is fixedly connected to the adjacent fixed plate.

[0065] When the mold 104 moves forward to prepare for die-casting again, the mold 104 drives the protrusion 501 to move forward and pass through the knocking rod 502 in turn. When the protrusion 501 passes through the knocking rod 502, the knocking rod 502 is squeezed to the left and right sides of the mold 104, so that the torsion spring is stressed. When the protrusion 501 passes over the knocking rod 502, the knocking rod 502 quickly rebounds and resets under the elastic force of the torsion spring, knocking the mold 104, causing the mold 104 to vibrate, and shaking the molding sand adhered to the mold 104 loose, which is beneficial to enhance the subsequent cleaning effect of the first cleaning brush 401 and the second cleaning brush 406 on the mold 104. When the mold 104 moves backward, the telescopic end of the sixth driving member 503 is controlled to extend, driving the knocking rod 502 to move toward the left and right sides of the mold 104, preventing the mold 104 from being stuck by the knocking rod 502 when driving the protrusion 501 to move backward, thereby ensuring the normal operation of the equipment.

[0066] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes may be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
