Description

Technical Field

[0001] This invention relates to the field of resin sand casting technology, specifically to a resin sand casting equipment and casting method. Background Technology

[0002] Resin sand casting is a common casting process, also known as cold core casting. It uses resin as a binder to hold sand particles together to form a sand mold. Molten metal is then poured into the mold, allowing it to solidify into the desired casting. Besides the mold itself, a pouring gate is required during sand filling. A pouring module typically occupies part of the resin sand space, and this module needs to be removed after casting. Currently, the removal of the pouring module is usually done manually, which is inefficient.

[0014] To better achieve the purpose of this invention, this invention also provides a method for casting resin sand, comprising the following steps: Step 1: Install the mold assembly, align the positioning hole with the positioning slide post, and slide the mold plate along the positioning slide post through the positioning hole until it contacts the first spring; Step 2: Start the linear guide rail. The linear guide rail drives the mounting plate to the mounting frame. At this time, the left half and right half of the receiving box are in a combined state. The left half and right half of the receiving box wrap around the mold plate and form a forming box. Start the sand injector on the mounting frame to inject sand into the forming box.

[0015] Step 3: During the operation of the left half of the container, the contact wheel moves from the lower end of the left side of the convex guide rail to the higher end of the middle. The height of the contact wheel increases, which drives the second push rod to rise. The second push rod pushes the second contact ball to make contact with the first contact ball. The first contact ball pushes the first push rod, so that the first push rod contacts the inner end of the casting cylinder. At this time, the casting cylinder is fixed. Step 4: The linear guide rail drives the molding box to reciprocate to receive sand injected by the sand injector. As the amount of sand increases, the mold plate compresses the first spring. Step 5: When there is enough sand, the linear guide rail drives the molding box to move again. At this time, the contact wheel moves from the higher end of the middle of the convex guide rail to the lower end on its right side. At this time, the pouring cylinder disengages from the first push rod. Step Six: Start the electric slide rail. The electric slide rail drives the support frame to move downward. The support frame drives the mounting plate, the first pressure plate, and the second pressure plate to move downward. The second pressure plate contacts and presses against the molding resin sand in the molding box so that it is in full contact with the mold plate. At this time, the second through hole is inserted into the upper end of the pouring cylinder. Then, start the cylinder. The cylinder drives the first pressure plate to press down. The first pressure plate presses down on the pressure block. The pressure block presses down on the punching column and compresses the second spring. The punching column opens a vent hole in the molding resin sand. Step 7: At the same time, the first pressure plate drives the arc-shaped pressure plate to press down. The lower end of the arc-shaped pressure plate slides in contact with the conical surface of the conical block. The conical block is forced to slide the third push rod in the connecting block and compress the fifth spring. The third push rod drives the arc-shaped pressure plate to move. The arc-shaped pressure plate comes into contact with the upper end of the casting cylinder, thereby fixing the casting cylinder. Step 8: After the resin sand has been fixed, start the motor. The motor drives the bidirectional threaded rod to rotate. The bidirectional threaded rod drives the left half of the receiving box and the right half of the receiving box to move away from each other on the first slide rod. At the same time, the positioning slide column slides with the first limiting slide groove, and the second limiting slide groove slides with the cylinder. At this time, the resin sand is exposed and is taken out by the feeding device.

[0016] Step 9: The linear guide rail drives the mounting plate back along the original path, while the pouring cylinder is repositioned at the concentric position of the positioning hole on the mold plate.

[0017] The present invention has the following technical effects: When this invention is used, the mold assembly is moved on the main body of the equipment by the movable receiving and adjusting component. When the movable receiving and adjusting component moves to the sand injection station of the main body of the equipment, the casting module of the mold assembly is fixed by the lower fixing component in cooperation with the main body of the equipment. Thus, the sand injection station of the movable receiving and adjusting component moves back and forth to ensure that the sand falling into the movable receiving and adjusting component and the mold assembly is evenly spread. Subsequently, the moving and accommodating adjustment component moves to the pressing and drilling station. At this time, the pressing and drilling component presses the sand in the moving and accommodating adjustment component and the mold component, so that the sand and the mold component are in full contact. At the same time, the air vent is opened on the formed sand. Then, the lower fixing component cooperates with the main body of the equipment to release the casting module of the mold component. The upper fixing component cooperates with the pressing and drilling component to remove the casting module, thereby realizing the automatic installation of the casting module.

[0036] In some embodiments, such as Figure 1-8 As shown, in a preferred embodiment of the present invention, the following steps are also included: Step 1: Install mold assembly 3, align the positioning hole 32 with the positioning slide post 213, and slide the mold plate 31 along the positioning slide post 213 through the positioning hole 32 until it contacts the first spring 215; Step 2: Start the linear guide 211. The linear guide 211 drives the mounting plate 212 to move to the mounting frame 12. At this time, the left half of the receiving box 221 and the right half of the receiving box 222 are in a combined state. The left half of the receiving box 221 and the right half of the receiving box 222 wrap around the mold plate 31 and form a molding box. Start the sand injector 13 on the mounting frame 12 to inject sand into the molding box.

[0037] Step 3: During the operation of the left half of the receiving box 221, the contact wheel 518 moves from the lower end of the left side of the convex guide rail 14 to the higher end of the middle. The height of the contact wheel 518 increases, causing the second push rod 515 to rise. The second push rod 515 pushes the second contact ball 516 to come into contact with the first contact ball 514. The first contact ball 514 pushes the first push rod 513, so that the first push rod 513 comes into contact with the inner end of the casting cylinder 34. At this time, the casting cylinder 34 is fixed. Step 4: The linear guide rail 211 drives the molding box to reciprocate to receive the sand injected by the sand injector 13. As the amount of sand increases, the mold plate 31 compresses the first spring 215. Step 5: When there is enough sand, the linear guide rail 211 drives the molding box to move again. At this time, the contact wheel 518 moves along the middle of the convex guide rail 14 from the higher end to the lower end on its right side. At this time, the pouring cylinder 34 disengages from the first push rod 513. Step Six: Start the electric slide rail 411. The electric slide rail 411 drives the support frame 412 to move downward. The support frame 412 drives the mounting plate 413, the first pressure plate 414, and the second pressure plate 415 to move downward. The second pressure plate 415 contacts and presses against the molding resin sand in the molding box so that it fully contacts the mold plate 31. At this time, the second through hole 416 is inserted into the upper end of the pouring cylinder 34. Then, start the cylinder 421. The cylinder 421 drives the first pressure plate 414 to press down. The first pressure plate 414 presses down the pressure block 424. The pressure block 424 presses down the punching column 422 and compresses the second spring 423. The punching column 422 opens a vent hole in the molding resin sand. Step 7: Simultaneously, the first pressure plate 414 drives the arc-shaped pressure plate 526 to press down. The lower end of the arc-shaped pressure plate 526 slides in contact with the conical surface of the conical block 523. The conical block 523 is forced to slide the third push rod 522 in the connecting block 524 and compress the fifth spring 525. The third push rod 522 drives the arc-shaped pressure plate 526 to move. The arc-shaped pressure plate 526 contacts the upper end of the casting cylinder 34, thereby fixing the casting cylinder 34. Step 8: After the molding resin sand is fixed, start the motor 231.
