Abstract
The utility model discloses a casting mold for a solid cam shaft. The mold comprises a pouring cup, wherein the pouring cup is connected with a dead head; a filter leaf is arranged on the dead head, and connected with the outlet of the pouring cup; the outlet of the dead head is connected with the inlet at the front end of a cavity through an ingate; the outlet at the tail end of the cavity is connected with an exhaust riser; a plurality of chilling block seats are arranged on the cavity; a small vent needle is arranged on each chilling block seat, and a large vent needle is arranged on the exhaust riser. By adopting the mold, the content of carbide at the tail end of the cam shaft, and the defects such as air holes and included slag of the overall product can be effectively reduced, and the process yield of the casting is improved when the percent of pass of the casting is improved.
Description
Technical field
The utility model belongs to casting device, is specifically related to a kind of solid camshaft casting die.
Background technology
Camshaft is parts in piston engine.Its effect is to control the action of the opening and closing of valve.Although the rotating speed of camshaft is half (rotating speed at two stroke engine convexity wheel shaft is identical with bent axle) of bent axle in four-stroke engine, but its rotating speed is still very high conventionally, and need to bear very large moment of torsion, therefore very high in the requirement aspect intensity and support to camshaft in design, its material is generally Special Casting Iron, also has once in a while and adopts forging.Because valve motion rule is related to power and the service performance of an engine, so camshaft is manufactured in the manufacture process of engine in occupation of consequence very.
Casting, is that Metal Melting is smelt and meets necessarily required liquid and water in casting mold, obtains the technical process of the foundry goods (part or blank) of reservation shape, size and performance through cooled and solidified, after leveling processing.The blank of Foundry Production is with low cost, for part complex-shaped, that particularly have complicated inner cavity, more can demonstrate its economy; Its adaptability is wider simultaneously, and has good comprehensive mechanical performance.
The mould that the casting technique of existing production camshaft adopts adopts metal material to make, to the integrated poured moulding of camshaft.And generally mould is all that iron liquid is entered in many places, yield rate is low, and production efficiency is not high, and burr is large, and cleaning efficiency is low, and production cost is high.Also the Design of Runner System that has mould is that iron liquid is entered in one end, but tail end molten iron pressure head is less, in the time of feeding capacity deficiency, crosses chill water and concentrates on die cavity tail end, makes tail end carbide content high, and pore, the dreg defect of product integral body are more; Qualification rate is low.
Utility model content
The purpose of this utility model is to provide a kind of solid camshaft casting die, can effectively reduce pore, the dreg defect of camshaft tail end carbide content and product integral body, when improving casting qualification rate, has improved the product yield of foundry goods.
For achieving the above object, technical solution adopted in the utility model is:
This mould comprises cup, and cup connects rising head by cross gate, and filter disc is connected with cup outlet; Rising head outlet is connected with die cavity front end inlet by ingate; Die cavity end outlet connects exhaust rising head, is provided with a plurality of chill seats on die cavity, on each chill seat, is provided with little exhaust needle, is provided with large exhaust needle on exhaust rising head; Described cup, rising head, ingate, die cavity, exhaust rising head combine by upper die and lower die.
Preferably, on described rising head, be also provided with filter screen.
Preferably, described filter disc is ceramic filter disc.
Preferably, described filter screen is glass filter screen.
The beneficial effect that this solid camshaft casting die produces is: this mould can effectively reduce pore, the dreg defect of camshaft tail end carbide content and product integral body, has high product yield and high product percent of pass.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Schematic diagram when 2 casting moulds are used simultaneously when Fig. 2 is this casting.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail.
As shown in Figure 1 and Figure 2, this mould comprises cup 6, and cup 6 connects rising head 2 by cross gate, and filter disc 1 is connected with cup 6 outlets, and filter disc 1 plays filter residue effect, can reduce the impurity in molten iron, reduces the dreg defect in foundry goods; Rising head 2 outlets are connected with die cavity 7 front end inlet by ingate 4; Die cavity 7 end outlets connect exhaust rising head 5, on die cavity 7, be provided with a plurality of chill seats 8, the chill that lay chill seat 8 the insides can improve the cooling velocity of molten casting iron, make cam obtain white structure, guarantee casting quality, on each chill seat 8, be provided with float air tube 9, on exhaust rising head 5, be provided with large exhaust needle 10; Cup 6, filter disc 1, rising head 2, ingate 4, die cavity 7, exhaust rising head 5 combine by upper die and lower die, and the manufacturability of mould is better.
The preferred a kind of embodiment of this casting mould is, is also provided with filter screen 3 on rising head 2, and filter screen 3, with filter disc 1, plays filter residue effect, can reduce slag inclusion, inclusion defect in foundry goods.
The preferred a kind of embodiment of this casting mould is that filter disc 1 is ceramic filter disc.
The preferred a kind of embodiment of this casting mould is that filter screen 3 is glass filter screen.
While using this die casting camshaft, molten iron enters from cup 6, enters die cavity respectively by ceramic filter disc 1, cross gate 11, rising head 2, glass filter screen 3, ingate 4.By twice filter residue of ceramic filter disc 1 and glass filter screen 3, far-end is crossed chill water and is finally flowed into exhaust rising head 5, and the gas in die cavity is discharged outside die cavity by tail end exhaust rising head 5 exhaust needle 10 and the exhaust needle on chill seat 9 above.
Above-mentioned embodiment is used for the utility model of explaining; rather than the utility model is limited; in the protection domain of spirit of the present utility model and claim, any modification and change that the utility model is made, all fall into protection domain of the present utility model.
