Preferably, the vacuum extractor includes a vacuumizing joint, and described vacuumizing joint one end leads to the air-flow
Road is connected, and the other end of the vacuumizing joint is connected with a vavuum pump.
Preferably, between the vacuumizing joint and the gas channel by way of clamping or threaded connection or setting-in
It is fixedly linked.
Beneficial effects of the present invention：The present invention includes upper die and lower die, in addition to cast passage, and the cast passage is set
In on the upper mould, being additionally provided with die cavity in the lower mould, the cast passage is located at the upper edge of mould intracavity wall, makes cast liquid
Flowed down along mould intracavity wall, inspection passage is provided with the upper mould, the inspection passage end is connected with the die cavity, another
The side of the upper mould is stretched out at end, and the die cavity is also associated with a gas suction device.So the technical program is logical using cast
Road is located at the upper edge of mould intracavity wall, cast liquid is flowed down along mould intracavity wall, can be effectively prevented from liquid injection process
Produce bubble；The setting of passage is examined, whether can facilitate us observe die cavity fills up, and gas suction device can be by die cavity
Interior trapped gas is extracted out, and causes die cavity close to vacuum state, to avoid occurring due to having trapped gas in die cavity, so as to cause liquid in die cavity
Interior skewness, the illusive situation of welding.User experience is good, and application prospect is wide, so as to significantly enhance factory
The market competitiveness of family.
Brief description of the drawings
The present invention is further detailed explanation with reference to the accompanying drawings and detailed description.
Fig. 1 is a kind of sectional view of casting mould of the present invention.
Embodiment
It is to be appreciated that the directional instruction (such as up, down, left, right, before and after ...) of institute is only used in the embodiment of the present invention
Relative position relation under a certain particular pose (as shown in drawings) between each part, motion conditions etc. are explained, if the spy
When determining posture and changing, then directionality instruction also correspondingly changes therewith.In addition, it is related to " first ", " in the present invention
Two " etc. description is only used for describing purpose, and it is not intended that instruction or implying its relative importance or implicit indicating meaning
The quantity of the technical characteristic shown.Thus, " first " is defined, the feature of " second " can express or implicitly include at least one
Individual this feature.In addition, the technical scheme between each embodiment can be combined with each other, but must be with ordinary skill
Personnel can be implemented as basis, and this technical side is will be understood that when the combination appearance of technical scheme is conflicting or can not realize
The combination of case is not present, also not within the protection domain of application claims.
Reference picture 1, a kind of casting mould, including upper mould 10 and lower mould 20, in addition to cast passage 30, the cast passage
30 are arranged on the upper mould 10, and the cast passage 30 can be that circle can also be infundibulate, and mainly liquid is from mould
The passage that outside enters inside mould, die cavity 40 is additionally provided with the lower mould 20, and the cast passage 30 is located in die cavity 40
The upper edge of wall, cast liquid is flowed down along the inwall of die cavity 40, be provided with the upper mould 10 and examine passage 50, described examine is led to
The one end of road 50 is connected with the die cavity 40, and the other end stretches out the side of the upper mould 10, and the die cavity 40 is also associated with a gas
