Gravity casting equipment with casting model angle convenient to adjust

Abstract

The invention discloses gravity casting equipment with a casting model angle convenient to adjust, and relates to the field of gravity casting equipment. The gravity casting equipment comprises a baseand a deflection base, wherein a pair of symmetrically arranged support plate frames is welded on the upper surface of the base, the deflection base is rotatably connected with the upper ends of thetwo support plate frames through deflection rotating shafts welded on two sides correspondingly, and a die is fixed on a die holder arranged on the deflection base through bolts. According to the gravity casting equipment, a second motor is controlled to work, and a driving chain wheel arranged on an output shaft of the second motor is in transmission with a driven chain wheel through a chain, sothat the inclination of the deflection base is adjusted, namely the inclination angle of the die installed on the die holder is adjusted, a first motor is controlled to drive, and a first curved plateat the upper end of a conveying shaft of the first motor is linked with a second curved plate at the lower end of a rotating shaft through a connecting rod, so that the die holder reciprocates between +/-30 degrees, the die installed on the die holder is shaken, and a forming material filling inside the die is shaken uniformly.

Description

technical field [0001] The invention relates to the field of gravity pouring equipment, in particular to a gravity pouring equipment which is convenient for adjusting the angle of a pouring model. Background technique [0002] Gravity casting refers to the process in which molten metal is poured into the mold under the action of the gravity of the earth, also known as casting. The pouring mold is a tool used to produce casting products. The existing casting molds are generally fixed with fixtures or bolts before casting, and the angle of the casting mold cannot be adjusted during the pouring process. Especially the inside of the mold is a special-shaped molding cavity. If the angle of the mold cannot be adjusted, the pouring material cannot be fully and evenly filled in the molding cavity, which will affect the quality of the casting product. [0003] The Chinese patent application with the application number CN201310619575.7 discloses a tilting dual-force casting machine, ...

AI Technical Summary

Problems solved by technology

The above-mentioned technical solution has the following shortcomings and deficiencies: 1) The rotation angle of the formwork 3 is limited, and the molten metal cannot completely fill the cavity for some special-shaped cavities; The next casting process can only be carried out after cooling, the efficiency is relatively low, and because the cooling speed of the molten metal is very fast during the casting process, if its temperature decreases, its fluidity will slow down accordingly, which will affect the quality of casting

3) Due to the inertia of the flow of molten metal in the mold during the rotation of the mold base 3, it cannot be evenly filled in the cavity
