Abstract
The utility model discloses a circle cover forming combined die of engine cylinder body, it includes mould, lower mould, runs through loosing core of mould and lower mould, go up the cooperation of mould and lower mould and connect founding cavity of formation, the left and right sides of founding cavity is provided with left movable block, right movable block respectively, be provided with the notes wax mouth with founding cavity intercommunication on the lower mould, it is provided with the combination of left pin, the combination of right pin respectively to go up the mould both sides. Compared with the prior art the beneficial effects of the utility model are that: the utility model discloses a circle cover forming combined die of engine cylinder body, the equipment convenience is dismantled to its disconnect -type structure, and small in size can bear great heating load and mechanical load moreover.
Description
Technical field
This utility model relates to engine components technical field of mold, particularly relates to the round sleeve forming combination die of a kind of engine cylinder body.
Background technology
Automobile engine is to provide the internal combustion engine of power for automobile, is the heart of automobile, affects the dynamic property of automobile, economy and the feature of environmental protection；Source according to power source is different, and automobile engine is divided into Diesel engine, automobile engine, electric automobile motor and hybrid power engine；Common automobile engine is stroke piston combustion engine, make the mould of circle set, itself precision or anti-extrusion intensity are not the most the strongest, therefore the circle set voltage endurance capability manufactured is poor, the heat easily distributed inside electromotor and pressure crimp, cause engine oil leakage out, finally affect the normal operation started.
Utility model content
This utility model provides the round sleeve forming combination die of a kind of engine cylinder body, overcome the mould making circle set, itself precision or anti-extrusion intensity are not the most the strongest, therefore the circle set voltage endurance capability manufactured is poor, the heat easily distributed inside electromotor and pressure crimp, cause engine oil leakage out, finally affect the normal operation started.
The round sleeve forming combination die of a kind of engine cylinder body of the present utility model, it is characterised in that: it includes upper die and lower die, runs through loosing core of upper die and lower die；Described upper die and lower die are connected and form a founding cavity；The left and right sides of described founding cavity is respectively arranged with left movable block, right movable block；The casting mouth connected with founding cavity it is provided with in described lower mold；Described upper mold both sides are respectively arranged with the combination of left pin, the combination of right pin.
The round sleeve forming combination die of engine cylinder body of the present utility model, being sent the pin that left pin is combined as more than two, the combination of described right pin is also the pin of more than two.
The round sleeve forming combination die of engine cylinder body of the present utility model, the upper and lower two ends of described upper mold are respectively arranged with the upper alignment pin of fixation, lower alignment pin.
Compared with prior art the beneficial effects of the utility model are: the round sleeve forming combination die of a kind of engine cylinder body of the present utility model, its separate type structure, dismantle easy to assembly, compact, and can bear bigger thermic load and mechanical load.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of the round sleeve forming combination die of a kind of engine cylinder body of the present utility model；
Fig. 2 is the sectional structure schematic diagram in the B-B direction of Fig. 1.
Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, detailed description of the invention of the present utility model is described in further detail.Following example are used for illustrating this utility model, but are not limited to scope of the present utility model.
As Figure 1-Figure 2, the round sleeve forming combination die of a kind of engine cylinder body of the present utility model, it include upper mold 1, lower mold 2, run through upper mold 1 and lower mold 2 loose core 3；Described upper mold 1 and lower mold 2 are connected and form a founding cavity 12；The left and right sides of described founding cavity 12 is respectively arranged with left movable block 6, right movable block 7；The casting mouth 8 connected with founding cavity 12 it is provided with in described lower mold 2；Described upper mold 1 both sides are respectively arranged with left pin combination 4, right pin combination 5, wherein, the round sleeve forming combination die of engine cylinder body of the present utility model, the pin being sent left pin combination 4 to be more than two, and described right pin combination 5 is also the pin of more than two.
The round sleeve forming combination die of engine cylinder body of the present utility model, described upper mold about 1 two ends are respectively arranged with the upper alignment pin 10 of fixation, lower alignment pin 9, described upper alignment pin 10 is through lower mold 2 and is fixed on required fixing equipment, and described lower alignment pin 9 is fixed on required fixing equipment through lower mold 2.
Operation principle；First being sealed by casting mouth 8 wax candle water, then material adds the passage loosed core outside 3, material enters founding cavity 12 along with passage, wait cooled after upper mold 1 and lower mold 2 are separated, circle set is taken out.
Compared with prior art the beneficial effects of the utility model are: the round sleeve forming combination die of a kind of engine cylinder body of the present utility model, its separate type structure, dismantle easy to assembly, compact, and can bear bigger thermic load and mechanical load.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; on the premise of without departing from this utility model know-why; can also make some improvement and modification, these improve and modification also should be regarded as protection domain of the present utility model.
