Description
Technical field
The utility model relates to a kind of casting mould in auto parts and components field, is specifically related to a kind of engine cylinder cover casting mould.
Background technology
Cylinder cap part shape is complicated, compact conformation, is one of vital part affecting engine performance.The speed that the traditional cylinder cover mould design and manufacture method cycle is long, the number of occurrence is many, serious restriction new product is put on market.Wherein patrix adopts sand mo(u)ld, and its die cavity exit is provided with rising head, and its weak point is that patrix access times are few, cost is high, and sand mold patrix needs very large rising head to carry out feeding foundry goods in casting process, causes the waste of a large amount of aluminium liquid, also need after manufacture to cut rising head, labour intensity is large.And in traditional full sand casting mould, full sand casting mould cannot effectively be vented, casting difficulty is comparatively large, easily produces pore and shrinkage defect.
Utility model content
The utility model object is to provide a kind of engine cylinder cover casting mould, to solve in prior art that work difficulty is large, mechanical function is poor and the problem such as production efficiency is low.
The utility model solves the technical scheme that its technical problem adopts: a kind of engine cylinder cover casting mould, comprise metal pattern die and inner chamber core mechanism, described metal pattern die is by upper, counterdie, left, right mould and bed die surround, die cavity is provided with in the middle of described metal pattern die, described inner chamber core machine is set up in described die cavity, described inner chamber core mechanism's end face and described counterdie end face are respectively equipped with top overflow lip and sidepiece overflow lip, described bed die is provided with cup, on described, counterdie is all built-in with horizontal running channel, the bottom of described horizontal running channel is provided with some vertical-gating, described horizontal running channel communicates with described cup.
Further, described patrix is metal pattern, and described die cavity upper top is closed.
Further, the shape of cross section of described horizontal running channel is trapezoidal.
Further, described inner chamber core mechanism combines preparation by cold core and hot box process.
Further, described cylinder cap material is alusil alloy, and uniform wall thickness is interval between 4-5mm.
Further, described cup quantity is one, and adopts high temperature resistant material to make.
Further, described top overflow lip and sidepiece overflow lip can realize supplementing casting process.
Further, described vertical-gating is all communicated with the die cavity be located in described metal pattern die.
Further, need to be preheating between 200 DEG C-350 DEG C before described metal pattern die casting.
Compared to prior art, this utility model can not only reduce cylinder cap manufacturing cost, reduces work difficulty, and can improve the sealing of cylinder cap, improves dimensional accuracy, ensures the quality of production of manufactured materials utilization rate and foundry goods.
Accompanying drawing explanation
Fig. 1 is a kind of engine cylinder cover casting mould structure schematic diagram in the utility model embodiment.
Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with detailed description of the invention also with reference to accompanying drawing, the utility model is further described.Should be appreciated that, these describe just exemplary, and do not really want to limit scope of the present utility model.In addition, in the following description, the description to known features and technology is eliminated, to avoid unnecessarily obscuring concept of the present utility model.
With reference to shown in Fig. 1, in the utility model embodiment, a kind of engine cylinder cover casting mould, comprise metal pattern die 100 and inner chamber core mechanism 221, described metal pattern die 100 is by patrix 22, counterdie 23, left mould 30, right mould 33 and bed die 18 surround, die cavity 13 is provided with in the middle of described metal pattern die 100, described inner chamber core mechanism 221 is placed in described die cavity 13, described inner chamber core mechanism 221 end face and described counterdie 23 end face are respectively equipped with top overflow lip 11 and sidepiece overflow lip 55, described bed die 18 is provided with cup 80, described patrix 22, counterdie 23 is all built-in with horizontal running channel 77, the bottom of described horizontal running channel 77 is provided with some vertical-gating 10, described horizontal running channel 77 communicates with described cup 80.
Preferably, described patrix 22 is metal pattern, and described die cavity 13 upper top is closed.Preferably, the shape of cross section of described horizontal running channel 77 is trapezoidal.Preferably, described inner chamber core mechanism 221 is combined by cold core and hot box process and is prepared from.Preferably, described cylinder cap material is alusil alloy, and uniform wall thickness is interval between 4-5mm.Preferably, described cup 80 quantity is one, and adopts high temperature resistant material to make.Preferably, described top overflow lip 11 and sidepiece overflow lip 55 can realize supplementing casting process.Preferably, described vertical-gating 10 is all communicated with the die cavity 13 be located in described metal pattern die 100.Preferably, described metal pattern die 100 needs to be preheating between 200 DEG C-350 DEG C before casting.
Casting system in a kind of engine cylinder cover casting mould of the present utility model is made up of described cup 80, horizontal running channel 77, vertical-gating 10 and inner chamber core mechanism 221.In operating process, usually need complete the casting of cylinder cap through steps such as preheating-melting-lower core-matched moulds-casting-cooling-die sinkings.During casting, be that the alusil alloy solution of 700-730 DEG C is from injection in described cup 80 by temperature, then the die cavity 13 of described metal pattern die 100 is entered into through described horizontal running channel 77 and vertical-gating 10, again through the supplementary casting process of cooling processing and described top overflow lip 11 and sidepiece overflow lip 55, thus be frozen into required foundry goods, finally realize the smooth demoulding of cylinder cap.
In sum, compared to full sand mold cylinder cap casting mould, this utility model can not only reduce cylinder cap manufacturing cost, reduce work difficulty, and the sealing of cylinder cap can be improved, improve dimensional accuracy and mechanical performance, ensure the quality of production of manufactured materials utilization rate and foundry goods.Meanwhile, its technique effect it also avoid the casting flaw such as shrinkage porosite, pin hole, pore easily produced in cylinder cap casting process, meets the high-quality requirement in market.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on description, must determine its technical scope according to right.
