Description

Technical Field

[0001] This utility model relates to the technical field of resin sand mixing machines, specifically to a resin sand casting equipment. Background Technology

[0002] Resin sand is a type of foundry sand, which includes molding sand, curing agent, and resin. By mixing molding sand, curing agent, and resin, the molding sand and curing agent can be wrapped around the outside of the molding sand to obtain resin sand. Then, the resin sand is injected into the mold and left to harden by itself, or cured by heating or atomization. The resin sand mixer is mainly used for mixing sand, which adds curing agent and resin while stirring the molding sand.

[0003] Existing resin sand is prone to clumping during casting sand mixing, affecting mixing efficiency; and existing resin sand mixers are also prone to accumulating at the discharge port during the discharge process, leading to discharge port blockage. Utility Model Content

[0016] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. However, the specific implementation methods and embodiments described below are for illustrative purposes only and are not intended to limit the present invention.

[0017] See attached diagram. Figures 1 to 5 This embodiment of a resin sand casting equipment includes a frame 1, a storage box 2 at the top of the frame 1, a feed pipe 20 at the output end of the storage box 2, a crushing box 3 at the outlet end of the feed pipe 20, a crushing mechanism above the crushing box 3, a mixing box 8 below the crushing box 3, a stirring motor 80 on one side of the mixing box 8, a stirring device at the output end of the stirring motor 80 (the stirring device can be considered as prior art), and a discharge pipe 9 at the bottom of the mixing box 8, with vibration motors 90 on both sides of the discharge pipe 9.

[0018] Furthermore, the crushing mechanism includes a mounting plate 4 fixedly connected to the frame 1. A drive motor 40 is provided on one side of the mounting plate 4. A turntable 5 is provided at the output end of the drive motor 40. An eccentric shaft 50 is provided on the turntable 5. A swing rod 7 is slidably provided at one end of the eccentric shaft 50. A rotating shaft 51 is provided between the swing rod 7 and the mounting plate 4. A sliding groove 70 is provided on the swing rod 7. One end of the eccentric shaft 50 is slidably connected to the sliding groove 70. A sector gear 71 is provided at one end of the swing rod 7. A rack 6 is meshed on one side of the sector gear 71. A slide rail 41 is provided on one side of the mounting plate 4. The bottom of the rack 6 is slidably connected to the slide rail 41.

[0019] Furthermore, one end of the rack 6 is provided with a crushing disc 60, and the surface of the crushing disc 60 is provided with several sharp protrusions.

[0020] Furthermore, the bottom of the crushing box 3 is provided with a rotating connecting opening and closing plate 30; a cylinder 31 is hinged to the inner side wall of the bottom of the crushing box 3, and a push rod 32 is provided at the output end of the cylinder 31, one end of the push rod 32 is hinged to the opening and closing plate 30.

[0021] Furthermore, a support rod 81 is provided at the bottom of the mixing tank 8.

[0022] Working principle: In the crushing mechanism, the drive motor 40 drives the turntable 5 to rotate. The eccentric shaft 50 on the turntable 5 slides with the sliding groove 70 of the swing rod 7, causing the swing rod 7 to swing around the rotating shaft 51. This drives the sector gear 71 to mesh with the rack 6, and the swing rod 7 swings up and down, which in turn drives the rack 6 to move up and down in the slide rail 41, thereby causing the crushing disc 60 to move up and down. The sharp protrusions on the surface of the crushing disc 60 can fully crush the material entering the crushing box and prevent agglomeration. Then, the cylinder 31 drives the top rod 32 to move, causing the opening and closing plate 30 to open and close, so that the material falls into the mixing box 8 for mixing, and then is discharged at the discharge pipe 9. When discharging, the vibration motor 90 is started to avoid clogging of the discharge pipe 9.

[0023] It should be noted that in this embodiment, the drive motor, stirring motor, cylinder, vibration motor and stirring device can all be regarded as prior art. They are all controlled by an external controller, and the installation position and movement of the crushing disc and cylinder do not interfere with each other.

[0024] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
