Description

Technical Field

[0001] The utility model relates to the technical field of castable molds, in particular to an anti-cracking castable mold. Background Technique

[0002] The cracking of the material in the castable mold directly affects the physical properties of the castable molded product. In order to prevent the material in the castable mold from cracking, the following measures can be taken. During the casting process, the casting volume can be reasonably adjusted according to the structure of the mold and the properties of the casting material. During the construction process, pay attention to the control of vibration and casting speed, use a vibrator for sufficient vibration, and control the casting speed within a reasonable range. In the case of high temperature or strong wind, take measures to keep the casting material moist and delay the drying speed of the material, such as using methods such as water spraying or shielding. At present, when using manual vibration or manual control of water spraying, the manual operation will make the vibration quality and the control of the spraying time inaccurate, the vibration effect is inconsistent, and the required moist environment of the casting material cannot be accurately controlled. An improvement is urgently needed. Therefore, we propose an anti-cracking castable mold. Content of the Utility Model

[0003] The purpose of the utility model is to provide an anti-cracking castable mold, which solves the problems raised in the background technique.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0017] Embodiment 1, as Figure 1-2As shown in the figure, the present utility model provides a technical solution: an anti-cracking castable mold, which includes a mold frame 2, a bottom template 1, a hydraulic lifting mechanism 3, a platform base 4, a pump body 6, a turntable 8, a vibrator 7 eccentrically arranged on the surface of the turntable 8, and a motor 9 for driving the turntable 8 to rotate. The hydraulic lifting mechanism 3 includes four hydraulic cylinders distributed at the four right angles at the top of the bottom template 1. The top ends of the push rods of the four hydraulic cylinders are fixedly connected to the bottom of the platform base 4. Both sides of the bottom of the platform base 4 are fixedly provided with atomizing nozzles 5. The input ends of the two atomizing nozzles 5 are communicated with the output end of the pump body 6, and the input end of the pump body 6 is communicated with a water source pipe. The turntable 8 is rotatably arranged at the center of the platform base 4. An annular tooth 801 is integrally formed on the side wall surface of the turntable 8 protruding above the platform base 4. The motor 9 is fixed to the top of the platform base 4 through an L-shaped bracket 10. A gear 11 is coaxially arranged on the motor shaft of the motor 9, and the gear 11 meshes with the annular tooth 801.

[0018] In a specific embodiment of the present utility model, the input end of the pump body 6 is connected to the water source pipe. The start and stop of the pump body 6 are controlled by a controller. The controller sets the start interval period and the start time, and sets that the pump body 6 starts once every 2 hours, and each start time is 30 minutes. The hydraulic source of the hydraulic lifting mechanism 3 is provided by a hydraulic station. The lifting control of the hydraulic lifting mechanism 3 is controlled by a liquid control component. The structure of the turntable 8 is as Figure 2 shown. The platform base 4 is provided with a stepped groove, and balls are arranged in the stepped groove to realize the rotation of the turntable 8. The start of the motor 9 is independently controlled by a motor controller. The above-mentioned controllers are all integrated on a control cabinet (not shown in the figure). When the hydraulic lifting mechanism 3 lowers the platform base 4, the vibrating rod 701 of the vibrator 7 is located inside the mold frame 2. The inside of the mold frame 2 is filled with castable. The vibrator 7 and the motor 9 are started. The motor 9 drives the gear 11 to rotate. The gear 11 meshes with the annular tooth 801 to drive the whole turntable 8 to rotate. The vibrator 7 rotates eccentrically around the turntable 8. At this time, the vibrating rod 701 of the vibrator 7 vibrates and stirs inside the mold frame 2, so that the castable inside the mold frame 2 is fully contacted, reducing voids and bubbles. Subsequently, the platform base 4 is lifted, so that the vibrating rod 701 of the vibrator 7 is separated from the inside of the mold frame 2. At this time, the pump body 6 is intermittently started, and the atomizing nozzles 5 are used to spray the castable inside the mold frame 2 periodically, avoiding the situation of void cracks caused by the rapid air drying of the castable.

[0019] In the preferred technical solution, a tee pipe is connected and installed at the output end of the pump body 6. The two output ends of the tee pipe are respectively communicated with the input ends of the two atomizing nozzles 5 through pipelines. The tee pipe is used for the pump body 6 to output water mist at the two atomizing nozzles at the same time. The horizontal distance from the atomizing nozzle 5 to the mold frame 2 is set to 2 cm to avoid damage to the mold frame 2 caused by the collision of the atomizing nozzle 5 during the lifting and lowering of the platform base 4.

[0020] In a preferred technical solution, the vibrator 7 includes a machine head and a vibrating rod 701. The vibrating rod 701 penetrates through the turntable 8 and extends into the mold frame 2. The machine head drives the vibrating rod 701 to vibrate. The vibration of the vibrating rod 701 inside the mold frame 2 can accelerate the filling and flow between the castables.

[0021] In a preferred technical solution, extension seats 12 are fixedly arranged on both sides of the platform base 4. The tops of the push rods of the four hydraulic cylinders are fixedly connected to the bottoms of the extension seats 12. The extension seats 12 are used to connect the hydraulic lifting mechanism 3 and the platform base 4.

[0022] In a preferred technical solution, the pump body 6 is fixed to one side of the top of the platform base 4. The pump body 6 and the motor 9 are respectively distributed on the left and right sides of the turntable 8. The pump body 6 and the motor 9 are separately arranged, which is beneficial to balancing the gravity at the left and right ends of the platform base 4.

[0023] In summary, this embodiment provides a stirring and vibrating structure that can accelerate the full mixing and contact of the castable in the castable mold and reduce the bubble voids, and at the same time provides a structure for periodically spraying water to moisten the castable during solidification, so as to reduce the bubble voids during the mixing of the castable and avoid cracks caused by rapid air drying during the solidification of the castable, ultimately improving the product quality after the castable solidifies.
