Description

Technical Field

[0001] The utility model relates to the technical field of molding sand molds, and more specifically, the utility model relates to a vibration and leveling mechanism for vibrating molding sand in a mold. Background Art

[0002] Molding sand can be divided into facing sand, filling sand, single sand, etc. Facing sand is a layer of molding sand that adheres closely to the casting, and has high quality requirements. Filling sand is behind the facing sand layer and does not come into contact with the molten metal, and has less strict quality requirements. Single sand is a type of molding sand that does not distinguish between facing sand and backing sand, and is mainly used for machine molding. In addition, the sand molds of large castings often need to be dried before pouring, and the molding sand used in it contains more clay, and this type of molding sand is called dry mold sand; medium and small castings are often cast with a wet mold, and the molding sand used in it contains less clay, and this type of molding sand is called wet mold sand;

[0003] The molding sand in the molding sand mold needs to be vibrated and leveled. At present, most of the existing vibration and leveling mechanisms for vibrating molding sand in the market can only vibrate simply, and it is difficult to adjust the speed of the vibration frequency according to needs, resulting in poor vibration and leveling effects. Summary of the Utility Model

A plurality of second protrusions distributed in a ring shape are fixedly installed on the lower surface of the second fixing ring. A third fixing ring is fixedly installed on the lower surface of the circular chassis and outside the second fixing ring. A plurality of third protrusions distributed in a ring shape are fixedly installed on the lower surface of the third fixing ring.

[0008] As a preferred technical solution of the present invention, the molding sand mold is clamped between the two side plates by the limit bolts.

[0009] As a preferred technical solution of the present invention, the driving assembly includes a fixed support plate. The fixed support plate is fixedly installed above the support bent plate. An I-shaped rotating shaft is rotatably penetrated through the middle of the fixed support plate. A rotating disc is fixedly installed at the top of the I-shaped rotating shaft.

[0010] As a preferred technical solution of the present invention, the I-shaped rotating shaft is driven by a driving motor. A motor support is fixedly installed at the bottom of the fixed support plate. The driving motor is fixedly installed on the motor support.

[0011] As a preferred technical solution of the present invention, a square accommodating cavity is formed inside the rotating disc.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] The utility model fixes the sand molding mold on the top of the supporting plate by a limiting bolt, and then adjusts the position of the hemispherical protrusion according to the speed of the required vibration frequency, so that the hemispherical protrusion corresponds to the protrusion one, the protrusion two or the protrusion three. The specific operation is to rotate the adjusting knob to rotate the threaded rod, thereby driving the moving slider to move. Since the hemispherical protrusion is fixed on the moving slider, the movement of the moving slider will drive the hemispherical protrusion to move, thereby realizing the adjustment of the position of the hemispherical protrusion, and then start the control switch of the driving motor, and drive the I-shaped rotating shaft, the rotating disk and the hemispherical protrusion to rotate through the driving motor.
