Abstract
The invention discloses a casting molding machine, comprising a half sand box and a half model, wherein a rotating shaft is rotatably supported into holes in left and right side plates at the upper end of a rack; the half model is fixed on the rotating shaft, and is a semi-cylinder body; a semicircular groove matched with a belt or a wire rope is formed in the periphery of the semi-cylinder body; a molding plate is fixed at the upper end of the rack; an opening matched with the half model is formed in the molding plate; the upper surface of the molding plate is leveled with the axis of the rotating shaft; a sand box locating block is arranged on the upper surface of the molding plate; a turning handle is arranged at the outer end of the rotating shaft, and opposite to two locating pins at the end face of the molding plate respectively. The casting molding machine has significant advantages of high production efficiency and low cost.
Description
Technical field:
The present invention relates to a kind of foundry goods Modeling Technology, particularly a kind of foundry goods moulding machine.
Background technology:
Belt pulley or pulley often adopt the method for casting to make blank, existing formative method is to be placed on respectively and in upper and lower sandbox, after moulding, to be taken out two half models by two half models, making upper and lower sandbox be buckled into one casts, the cannelure that there is no desired endless-belt groove on the pulley of casting or the side face of belt pulley or be arc with the cross section that steel wire rope matches, need make above-mentioned cannelure by machining, cost is high.
Summary of the invention:
The object of this invention is to provide a kind of a kind of foundry goods moulding machine that can make cannelure on the foundry goods face of cylinder.
The technical scheme that realizes the object of the invention is, a kind of foundry goods moulding machine, comprise half sandbox and half model, it is characterized in that: rotating shaft is rotatably supported in the hole of frame upper end left side plate, half model described in fixing one in described rotating shaft, described half model is hemicycle cylinder, described half cylindrical side face is provided with the semi-circular groove matching with belt or steel wire rope, upper end in described frame is fixed with profiled sheeting, on this profiled sheeting, have the mouth matching with described half model, the upper surface of described profiled sheeting is equal with the axis of described rotating shaft, be provided with sandbox locating piece at the upper surface of described profiled sheeting, the outer end of described rotating shaft is provided with turns handle, this turns relative with two alignment pins on described profiled sheeting end face respectively.
The present invention has the expensive low remarkable advantage of production efficiency compared with the prior art.
Accompanying drawing explanation:
Fig. 1 is the structural representation that half belt pulley model of the present invention is placed in the foundry goods moulding machine state in drag box; Fig. 2 is the structural representation that the another half belt pulley model of the present invention shifts out cope state after drag box moulding.
The specific embodiment:
Analyze the forming method of existing sand mold, in the time that half model takes out from sandbox, employing be manual taking-up, can not guarantee that model departs from the die cavity in sandbox exactly, cause groove shape change, so model is not with cannelure.In order to address the above problem, the present invention adopts following proposal, rotating shaft 4 is rotatably supported in the both sides plate hole of described frame 1 upper end, the diameter of described rotating shaft is identical with the aperture of described belt pulley, the model 6 of half belt pulley is fixed on half side face of described rotating shaft, be provided with a profiled sheeting in described frame upper end, on this profiled sheeting, have with described rotating shaft on half belt pulley model match mouth, the left end of described rotating shaft stretches in frame outward and is provided with and turns 3, before the left side of the profiled sheeting of described frame upper end, rear side be respectively equipped with an alignment pin 2 with described in turn relative, the axis of described rotating shaft is equal with the upper surface of described forming board, described half belt pulley model is hemicycle cylinder, on this half cylindrical side face, be provided with the groove matching with belt or steel wire rope.
Operation principle of the present invention and method of operating, first rotate and turn making half model rotation to after directly over profiled sheeting, now turn being parked on an alignment pin fixing, second sandbox 5 is placed on profiled sheeting and makes behind sandbox location, just can carry out sand mold moulding, after moulding, reversion is turned and is parked on another alignment pin making half sand mold in rotating shaft depart from the below that sandbox enters profiled sheeting, now in second sandbox, form the cavity 7 of half foundry goods, just second sandbox can be shifted out, first sandbox is placed on profiled sheeting and location, rotation is turned shaping mould is placed in directly over profiled sheeting, just can back-up sand carry out moulding, after completing, make model depart from sandbox, taking-up cope and drag box fasten and cast, make the belt pulley with cannelure, the precision of this belt pulley is compared with high and do not need to carry out machining, efficiency is high, cost is low.Forming machine also can forming cylinder shape and cylinder on have other foundry goods of cannelure.
