Description

Technical Field

[0001] This utility model relates to the technical field of lost foam cutting equipment, specifically a cutting device for lost foam. Background Technology

[0002] Lost foam casting is a new type of casting process, also known as solid casting or vaporized foam casting. Its core principle is to use foam plastic (such as EPS, STMMA, etc.) to make a model with the same shape as the casting. By pouring molten metal, the model vaporizes and disappears, eventually forming a precision casting. During the production and processing of lost foam casting, cutting equipment is required to cut and process it.

[0003] A search revealed patent application CN202420456706.8, which discloses a lost foam cutting device, including a wire saw and a worktable. The wire saw is fixedly installed on the top of the worktable, and a fixing mechanism is provided on the top of the worktable to fix the lost foam. The fixing mechanism includes two motors fixedly installed on both sides of the worktable. This invention, by setting up a fixing mechanism and an adjustment mechanism, allows the motor in the fixing mechanism to rotate, driving a rotating rod and a threaded rod to rotate. This causes a transmission block to drive a sliding block and a clamping plate to clamp and fix the lost foam. Simultaneously, by manually pulling the stabilizing block in the adjustment mechanism, the tension generated by the tension spring causes the insertion pin and insertion block to disengage from the cylindrical hole and insertion hole. Used in conjunction with the adjustment mechanism, this device can fix irregularly shaped lost foam, thereby further improving the fixing effect and the practicality of the device.

[0004] However, this patent has its shortcomings. In actual use, the lost foam cutting device requires the operator to manually adjust the extension length of multiple fixing plates to fix the irregularly shaped lost foam at multiple points. This fixing method is cumbersome and time-consuming, and not convenient to use. At the same time, this lost foam cutting device lacks components that can position the lost foam cutting position. During the cutting process, the wire saw is prone to deviation on the lost foam, resulting in inaccurate dimensions of the cut lost foam and affecting the cutting quality.

[0005] Therefore, we propose a cutting device for lost foam casting. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1 to 3This utility model provides a cutting device for lost foam casting, including a base frame 1, a machine platform 2 fixedly mounted on the base frame 1, two fixed seats 14 on the machine platform 2, each fixed seat 14 having an air groove 15, and multiple receiving slots 16 located on the side of the two air grooves 15 close to each other in each fixed seat 14, with piston plates 17 slidably connected in each of the multiple receiving slots 16, and connecting rods 23 fixedly mounted at the ends of the multiple piston plates 17 away from the air grooves 15, with multiple connecting rods 23 extending out of the fixed seats 14 and fixedly mounted with clamps 18, a diversion box 12 fixedly mounted at the top of the machine platform 2, a suction pump 11 fixedly mounted at the bottom of the diversion box 12, and an air supply pipe on the suction pump 11 communicating with the inside of the diversion box 12, a threaded rod 8 rotatably connected in the base frame 1, a sliding beam 9 threadedly sleeved on the threaded rod 8, and a U-shaped frame 3 slidably sleeved on the outside of the base frame 1, with the front and rear ends of the sliding beam 9 extending out of the base frame 1 and fixedly mounted on the U-shaped frame 3.

[0022] L-shaped pointers 5 are fixedly installed at the front ends of both fixed seats 14, arrows 7 are fixedly installed on both sides of the front end of the U-shaped frame 3, and a scale 6 is fixedly installed at the front end of the machine base 2. This design facilitates the use of the equipment. A bidirectional cylinder 19 is fixedly installed inside the machine base 2. Slides 24 are fixedly installed on both output ends of the bidirectional cylinder 19. The tops of the two slides 24 extend out of the machine base 2 and are fixedly installed on the corresponding fixed seats 14. The bidirectional cylinder 19 drives the two fixed seats 14 to slide towards or away from each other, which facilitates the use of the equipment. Conveying pipes 13 are fixedly installed at both ends of the diversion box 12. The ends of the two conveying pipes 13 away from the diversion box 12 are respectively connected to the corresponding air tanks 15. Air is delivered to the air tank 15 through the delivery pipe 13, which is beneficial to the use of this equipment. Lifting cylinders 20 are fixedly installed at the bottom of the two output ends of the U-shaped frame 3. Mounting seats 21 are fixedly installed on the output ends of the two lifting cylinders 20. Heating wires 22 are fixedly installed between the two mounting seats 21. The lifting cylinders 20 drive the mounting seats 21 and heating wires 22 to lift and lower, which is convenient for cutting the lost foam. A motor 10 is fixedly installed on the left side of the base frame 1. The output end of the motor 10 is fixedly installed on the threaded rod 8. The motor 10 drives the threaded rod 8 to rotate, which is beneficial to the use of this equipment. A PLC controller 4 is fixedly installed on the base frame 1 in front of the motor 10. The PLC controller 4 is used to control the operation of this equipment.

[0023] Working principle: The PLC controller 4 is electrically connected to the motor 10, bidirectional cylinder 19, suction pump 11, heating wire 22, and lifting cylinder 20 via connecting wires. During use, the lost foam to be cut is placed on the machine base 2 between two fixed seats 14. The fixed switch is turned on, and the two output ends of the bidirectional cylinder 19 drive the two sliding blocks 24 and the fixed seats 14 to slide towards each other, clamping and limiting the lost foam on both sides. Simultaneously, the suction pump 11 operates, delivering air to the distribution box 12. The air passes through... Two delivery pipes 13 enter two air slots 15. As air is continuously supplied to the air slots 15, multiple piston plates 17 drive connecting rods 23 to extend beyond the receiving slots 16. When one of the clamps 18 abuts against the outer wall of the lost foam, the corresponding piston plate 17 and connecting rod 23 stop extending. Air then enters the other receiving slots 16, pushing the other piston plates 17 and connecting rods 23 to extend. Ultimately, the multiple connecting rods 23 extend to different lengths, causing the multiple clamps 18 to contact the outer side of the lost foam. Multi-point clamping and positioning are performed. Then, the motor 10 is switched on according to the cutting needs. The motor 10 drives the threaded rod 8 to rotate, causing the slide beam 9 to slide the U-shaped frame 3 to the left. The position of the two L-shaped pointers 5 on the scale 6 makes it easy for the operator to judge the overall length of the irregular lost foam. Then, the U-shaped frame 3 is adjusted to the appropriate position according to the position of the two arrows 7 on the scale 6 and then stopped. The cutting switch is turned on. At this time, the two lifting cylinders 20 drive the mounting base 21 and the heating wire 22 to descend, and the irregular lost foam can be cut. The circuit connection method, mechanical structure and connection relationship not mentioned in this specification are all conventional technical means in this field, so they will not be described in detail. This kind of lost foam cutting device is easy to use. Through the above components, the outer wall of the irregular lost foam can be quickly clamped and positioned at multiple points without manual adjustment, thereby further improving the convenience of using this equipment. At the same time, the position of the heating wire 22 on the lost foam can be precisely adjusted according to the needs of use, thereby further improving the cutting quality.
