Abstract
The utility model provides a skim gate stick, is equipped with on the lower face of apron and gathers sediment type pouring basin and buffer type directly waters the stick including the apron, and oral area and cover connection, the buffer type who gathers sediment type pouring basin directly waters the upper end and the cover connection of stick, gathers sediment type pouring basin and buffer type and directly waters and excellently water the connection through the current -limiting type and be a whole, on the apron on the face corresponding to gather sediment type pouring basin regional for the pouring district, directly to water the stick corresponding to buffer type regional for excellent core joining region. The advantage: 1. Gather sediment type pouring basin, can be with the shoddye gathering in it to reduce the cinder hole, 2. Buffer type directly waters the stick, can effectively slow down the molten steel velocity of flow to reduce the gas pocket defect, 3. The current -limiting type waters, can change the molten steel inlet flow rate, reduces the molten steel vortex and turbulent flow to reduce the gas pocket defect, 4. The utility model has the advantages of simple structure, the cost of manufacture is low, has improved work efficiency and product quality.
Description
Technical field
This utility model belongs to model casting field, especially a kind of pushing off the slag gate stick.
Background technology
1. tradition gate stick is without poly-slag, current limliting and pooling feature.Model casting uses gate stick in the majority, and molten steel directly pours into from straight line portion, it is easy to form turbulent flow and volume gas, thus increasing slag pore ratio.
2. the slag pore ratio of part steel-casting remains high, without effective solution.After portioned product machining, slag pore ratio is up to more than 8%.Adopt conventional pushing off the slag cotton or repeatedly slag making technology, cause percent defective reduction not yet in effect.
3. use current limliting block or drainage screen technology to reduce slag pore manufacturing cost high (5-8 unit/sheet).Cast steel is high with current limliting block or drainage screen real cost, and needs in use to be manually placed into, it is impossible in high volume.
Summary of the invention
For above-mentioned technical problem, this utility model provides a kind of pushing off the slag gate stick, the satisfied requirement being suspended on automatic shell line processed, roasting direct can pour into a mould, it is easy to operation, be beneficial to industrial mass application after module dewaxing.
In order to solve above-mentioned technical problem, the technical solution of the utility model is: a kind of pushing off the slag gate stick, it is characterized in that: include cover plate, the lower face of cover plate is provided with poly-slag type cup and buffer-type directly waters rod, the oral area of poly-slag type cup is connected with cover plate, buffer-type directly waters excellent upper end and is connected with cover plate, and poly-slag type cup and buffer-type directly water rod and connect as a whole by current-limiting type running channel；Cover plate upper face is pouring area corresponding to poly-slag type cup region, directly waters rod region corresponding to buffer-type for rod core bonding pad；Described buffer-type directly waters the structure of rod: including directly being watered rod by what multistage inversed taper platform series winding was constituted, the lower surface directly watering rod is provided with hemispherical projections.
To submitting a written statement to a higher authority, technical scheme further limits, and the structure of described poly-slag type cup is: including cast cup, the periphery of cast cup is wavy.The advantage of this structure: on undulated design can increase the contact surface of molten steel and cup, strengthen shoddye and suspend at wave place the probability assembled, thus reducing cinder hole.
To submitting a written statement to a higher authority, technical scheme further limits, and the structure of described current-limiting type running channel is: include the running channel of one section of arc.The advantage of this structure: its structure can change molten steel inlet flow rate, reduces molten steel eddy current and turbulent flow, further thus reducing gas hole defect further.
Beneficial effect: this practicality newly has the advantage that 1. poly-slag type cups, can be assembled within it by shoddye, thus reducing cinder hole；2. buffer-type directly waters the hemispherical projections that rod, side face structure thereon and bottom increase, and making molten steel be become laminar flow from eddy current, can effectively slowing down molten steel flow velocity, thus reducing gas hole defect；3. current-limiting type running channel, can change molten steel inlet flow rate, reduces molten steel eddy current and turbulent flow, thus reducing gas hole defect；4. simple in construction of the present utility model, cost of manufacture is low, improves work efficiency and product quality.

Detailed description of the invention
Such as Fig. 1, shown in Fig. 2 and Fig. 3, a kind of pushing off the slag gate stick, including cover plate 1, the lower face of cover plate 1 is provided with poly-slag type cup 2 and buffer-type directly waters rod, the oral area of poly-slag type cup 2 is connected with cover plate 1, buffer-type directly waters the upper end of rod and is connected with cover plate 1, poly-slag type cup 2 and buffer-type directly water rod and connect as a whole by current-limiting type running channel 3, namely current-limiting type running channel 3 is the running channel of one section of arc, the liquid feeding end of running channel is connected with the lower end of poly-slag type cup 2, liquid outlet directly waters the side face of rod and is connected with buffer-type, the liquid feeding end of running channel is slightly larger in dimension than liquid outlet size；The structure of described poly-slag type cup 2 is: including cast cup, the periphery of cast cup is wavy；Described buffer-type directly waters the structure of rod: including directly being watered rod 4 by what multistage inversed taper platform series winding was constituted, the lower surface directly watering rod is provided with hemispherical projections 5；Cover plate 1 upper face is pouring area 6 corresponding to poly-slag type cup 2 region, directly waters rod region corresponding to buffer-type for rod core bonding pad 7.
Using method: as shown in Figure 4,1. puts into mold cavity by pushing off the slag gate stick and rod core, prepares the pushing off the slag gate stick rod wax containing rod core；2. group tree；3., after group tree, it is suspended on automatic shell line processed by rod core 8, enters module shell operation；4. dewaxing, after using hot water to be dewaxed by formwork, takes out gate stick core, enters calcining process；5. cast, finally by sprue gate to casting metal solution in poly-slag type cup.
Do not elaborate in this specification part, for the known technology of ability.
