Abstract
The utility model provides a stalk for low pressure casting is equipped with the feed liquor hole in the bottom of this stalk, feed liquor hole and the inside intercommunication of stalk, the entry area in feed liquor hole is stalk flow area's 10~60%. The utility model discloses exempt from to let off the filter screen in making low pressure casting production, it is convenient to handle the runner stub bar, makes foundry returns increase iron still less.
Description
Technical field
This utility model belongs to light-alloy Low Pressure Casting Technology field.
Background technology
It is general in low pressure casting production to place drainage screen at water inlet cast gate, big problem is not included to small lot batch manufacture, it is right
Problem is just serious when the continuous production of high-volume especially is intended to realize full application of brake needs to increase adjust automatically drainage screen in space
Azimuth system, drainage screen is accurately continuously pushed to fixed position, drainage screen is taken up and be placed to water inlet
Mechanical hand, this is automatic production line arrangement, arrangement, debugs and bring many troubles, if can cancel it substantially reducing entirely
The fault rate and cost of automatic assembly line.In view of this, it is necessary to invent it is a kind of solve the above problems for low pressure casting
Stalk.
Utility model content
This utility model is solution above-mentioned technical problem, there is provided a kind of stalk for low pressure casting, in this liter of liquid
The bottom of pipe is provided with inlet opening, and the inlet opening is connected with stalk inside, and the inlet area of the inlet opening is stalk stream
The 10～60% of logical area.
Further, the opening of the inlet opening is downward.
Further, on the side wall of stalk, its opening is connected the inlet opening located at stalk side wall with bottom
Position on, and the opening is towards side.
Further, the wall thickness of the inlet opening is 3～40mm.
This utility model makes to exempt to let slip filter screen in low pressure casting production, processes cast gate stub bar conveniently, makes foundry returns increase ferrum more
It is few.
Description of the drawings
With reference to the accompanying drawings this utility model is further described in conjunction with the embodiments.
Fig. 1 is structural representation of the present utility model；
Fig. 2 is structural representation of the present utility model two.
Specific embodiment
Fig. 1 and 2 is referred to, is the stalk 1 for low pressure casting, in the bottom of the stalk 1 inlet opening 2, institute are provided with
State inlet opening 2 to connect with the inside of stalk 1, the inlet area of the inlet opening 2 is the 10～60% of the circulation area of stalk 1.
Such as Fig. 1, the opening of the inlet opening 2 is downward.Such as Fig. 2, the inlet opening 2 is located on the side wall of stalk 1,
Its opening is on the position that the side wall of stalk 1 is connected with bottom, and the opening is towards side.The wall thickness of the inlet opening 2
For 3～40mm.This utility model makes to exempt to let slip filter screen in low pressure casting production, processes cast gate stub bar conveniently, makes foundry returns increase ferrum
Less.
This utility model is exemplarily described above in conjunction with accompanying drawing, it is clear that this utility model is implemented not to be received
The restriction of aforesaid way, as long as employing changing for the various unsubstantialities that method design of the present utility model and technical scheme are carried out
Enter, or it is not improved by it is of the present utility model design and technical scheme directly apply to other occasions, in this utility model
Protection domain within.
