Abstract
The utility model discloses a moulding machine adopting pressure levers and a pressure plate for pressing and compacting casting sand respectively. The moulding machine comprises a frame 1, a pressure plate lifting oil cylinder 2, a pressure plate frame 3, a pressure lever lifting oil cylinder 4, a pressure lever plate 5, pressure levers 6 and the pressure plate 7. When the piston rod of the pressure lever lifting oil cylinder fixed in the pressure plate frame falls, the pressure lever plate fixed on the piston rod and the pressure levers fixed on the pressure lever plate fall synchronously, and the pressure levers penetrate through the pressure plate for pressing and compacting the casting sand in a plurality of sunk areas in a casting mould; and then the pressure levers are lifted and repositioned, the piston rod of the pressure plate lifting oil cylinder fixed on the frame falls, the pressure plate frame fixed on the piston rod and the pressure plate fixed at the lower end of the pressure plate frame fall together with the piston rod, and the pressure plate is enabled to press and compact the casting sand integrally. The moulding machine ensures the compactness of the casting sand in special areas of the casting mould, thereby reducing the surface defects of a cast and improving the qualification rate of the cast.
Description
Technical field
The utility model relates to the moulding machine in sand mold (or the half sand mold) casting, is meant a kind of pressurize respectively moulding machine of consolidation molding sand of depression bar and pressing plate that uses especially; Belong to the foundry machinery technical field.
Background technology
In sand mold (or half sand mold) Foundry Production, must arrive loose molding sand consolidation to a certain degree.At present the moulding machine of consolidation molding sand mainly contains the impeller ramming moulding machine, the consolidation moulding machine that jolt-squeezes, penetrates and compress real moulding machine.The moulding machine of above-mentioned consolidation molding sand, shortcoming are that the molding sand in indentation zone darker in the casting mold can not be by effective consolidation, and there is blemish in the foundry goods that causes producing at corresponding position, causes the percent defective of foundry goods too high.
The utility model content
The purpose of this utility model is to overcome the weak point of above-mentioned moulding machinery, provide a kind of can be with the moulding machine of the effective consolidation of molding sand in indentation zone in the casting mold, thereby improve the surface quality of foundry goods, reduce the casting wasted product rate.
The utility model realizes that the technical measures of above-mentioned purpose are: the molding sand in the casting mold is used depression bar and the pressing plate consolidation that pressurizes respectively; At first use the suitable several depression bars of cross sectional shape and size that the molding sand in several indentation zones in the casting mold is pressed, use the suitable pressing plate of shape and size that the molding sand in the casting mold is carried out the entire pressurisation consolidation then.
The above-mentioned depression bar of the utility model is fixed on the depression bar dish, and the depression bar dish that can fix several depression bars is fixed on the piston rod of depression bar hoist cylinder, and the depression bar hoist cylinder is fixed in the plate frame.
The above-mentioned pressing plate of the utility model is provided with the hole that can pass several depression bars, and depression bar bottom surface and pressing plate bottom surface place in one plane when depression bar resetted; Pressing plate is fixed on the lower end of plate frame, and the upper end of plate frame is fixed on the piston rod of pressing plate hoist cylinder, and the pressing plate hoist cylinder is fixed on the frame.
The depression bar hoist cylinder of installing in the above-mentioned plate frame of the utility model, when its piston rod moved downward, the depression bar dish moved downward thereupon, and several depression bars pass pressing plate, and the molding sand in several indentation zones in the casting mold is implemented the pressurization consolidation; After the piston rod of depression bar hoist cylinder, depression bar dish and depression bar rising resetted, the piston rod of pressing plate hoist cylinder moved downward, and plate frame moves downward thereupon, and the pressing plate that is installed in the plate frame lower end is implemented the entire pressurisation consolidation to the molding sand in the casting mold.Thus, each regional molding sand has reached suitable consolidation degree in the casting mold.
Description of drawings
Accompanying drawing 1 is pressurize the respectively structural representation of compact real form sand molding machine of the utility model depression bar and pressing plate
1-frame among the figure, 2-pressing plate hoist cylinder, 3-plate frame, 4-depression bar hoist cylinder, 5-depression bar dish, 6-depression bar, 7-pressing plate, 8-casting mold, 9-sand stop ring, 10-template.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment when the utility model is used for the abrading-ball foundry goods moulding of half sand casting is described.
The casting mold 8 of filling molding sand is placed on the below of pressing plate 7, and the piston rod of depression bar hoist cylinder 4 promotes depression bar dish 5 and moves downward, and two depression bars move downward thereupon and the molding sand in two indentation zones of casting mold is pressed; After the piston rod of depression bar hoist cylinder 4 and depression bar dish 5, depression bar 6 risings reset, the piston rod of pressing plate hoist cylinder 2 moves downward, plate frame 3 moves downward simultaneously together with the pressing plate 7 of plate frame lower end, molding sand in the casting mold 8 is carried out the entire pressurisation consolidation, the piston rod of pressing plate hoist cylinder 2 rising afterwards resets, plate frame 3 and pressing plate 7 rise simultaneously and reset, and have finished pressurize the respectively moulding of consolidation molding sand of depression bar and pressing plate.
Claims (1)
1. depression bar and the pressing plate moulding machine of consolidation molding sand that pressurizes respectively is characterized in that: use cross sectional shape and the suitable several depression bars of size to pass pressing plate the molding sand in several indentation zones in the casting mold is pressed; Use shape and the suitable pressing plate of size that the molding sand in the casting mold is carried out the entire pressurisation consolidation; Described depression bar is fixed on the depression bar dish, and the depression bar dish is fixed on the piston rod of depression bar hoist cylinder, and the depression bar hoist cylinder is fixed in the plate frame; Depression bar, depression bar dish, the depression bar hoist cylinder can be with the plate frame lifting; Described pressing plate is provided with the hole that can pass several depression bars; Pressing plate is fixed on the lower end of plate frame, and the upper end of plate frame is fixed on the piston rod of pressing plate hoist cylinder, and the pressing plate hoist cylinder is fixed on the frame.
