Abstract
The invention discloses a kind of foundry goods moulding machine, comprise half sandbox and half model, axis of rotation is supported in the hole of frame upper end left side plate, described rotating shaft is fixed half model described in, described half model is hemicycle cylinder, described half cylindrical side face is provided with the semi-circular groove matched with belt or steel wire rope, profiled sheeting is fixed with in the upper end of described frame, this profiled sheeting has the mouth matched with described half model, the upper surface of described profiled sheeting is equal with the axis of described rotating shaft, sandbox locating piece is provided with 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 low remarkable advantage of production efficiency high 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 placed on shaping rear taking-up two half models in upper and lower sandbox respectively by two half models, upper and lower sandbox is buckled into integrally cast, the pulley cast or the side face of belt pulley do not have required endless-belt groove or be the cannelure of 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 making cannelure on the foundry goods face of cylinder.
The technical scheme realizing the object of the invention is, a kind of foundry goods moulding machine, comprise half sandbox and half model, it is characterized in that: axis of rotation is supported in the hole of frame upper end left side plate, described rotating shaft is fixed half model described in, described half model is hemicycle cylinder, described half cylindrical side face is provided with the semi-circular groove matched with belt or steel wire rope, profiled sheeting is fixed with in the upper end of described frame, this profiled sheeting has the mouth matched with described half model, the upper surface of described profiled sheeting is equal with the axis of described rotating shaft, sandbox locating piece is provided with 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 low remarkable advantage of production efficiency high cost compared with the prior art.
Accompanying drawing illustrates:
Fig. 1 is the structural representation that the present invention's half belt pulley model 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 is shaping.
Detailed description of the invention:
Analyze the forming method of existing sand mold, when half model takes out from sandbox, employing be manual taking-up, can not ensure that model departs from the die cavity in sandbox exactly, cause groove shape to change, so model is not with cannelure.In order to solve the 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, a profiled sheeting is provided with in described frame upper end, this profiled sheeting has the mouth matched with half belt pulley model in described rotating shaft, stretching in frame outside the left end of described rotating shaft and being provided with turns 3, before the left side of the profiled sheeting of described frame upper end, rear side is respectively equipped with an alignment pin 2 and turns relative with described, the axis of described rotating shaft is equal with the upper surface of described forming board, described half belt pulley model is hemicycle cylinder, this half cylindrical side face is provided with the groove matched with belt or steel wire rope.
Operation principle of the present invention and method of operating, first rotating turns making after directly over half model rotation to profiled sheeting, now turn being parked on an alignment pin fixing, second sandbox 5 to be placed on profiled sheeting and after sandbox is located, just sand mold moulding can be carried out, the below that after moulding, reversion is turned making half sand mold disengaging sandbox in rotating shaft enter profiled sheeting is parked on another alignment pin, now form the cavity 7 of half foundry goods in second sandbox, just second sandbox can be shifted out, first sandbox to be placed on profiled sheeting and to locate, rotation is turned making shaping mould be placed in directly over profiled sheeting, just back-up sand moulding can be carried out, after completing, model is made to depart from sandbox, taking-up cope and drag box fasten casts, make the belt pulley with cannelure, the precision of this belt pulley is higher and do not need to carry out machining, efficiency is high, cost is low.Forming machine also forming cylinder shape and cylinder can have other foundry goods of cannelure.
