Abstract
The invention relates to a directional flow funnel device for pouring of a large-scale copper retainer, which is used in a first working procedure in the process of machining the copper bearing retainer. The directional flow funnel device for pouring of the large-scale copper retainer comprises baffles, a chute, a runner body, a funnel device of a runner terminal, and a pouring die; the baffles are fixed at both ends of the runner body; the chute capable of being connected with a centrifuge door is formed at the lower end of the runner body; the lower surface of the runner body is divided into three sections; the first section is a flat and straight part; the second section is a flow guide part which is inclined downwards by a certain angle; the third section is a runner body terminal part; and the funnel device is arranged at the runner body terminal part. According to the invention, the baffles can prevent splashing of casting molten copper in the process of pouring the casting molten copper; the inclined runner flow guide part takes a guide effect on the molten water and enables the molten copper to flow downwards; and when the molten copper enters the terminal part of the runner, the funnel device centralizes the molten copper, the molten copper directly flows to the inner wall of the pouring die and no reverse and splashed molten copper is generated, so that the defects of cast pores, laps and the like are avoided and production efficiency is improved.
Description
Technical field
The invention belongs to the retainer casting technology field, relate to concretely a kind of large-scale copper cage cast directed flow funnel device that worked copper retainer first operation is used that relates to.
Background technology
For large-scale copper cage, generally adopt sand casting, even adopt centrifugal casting, its qualified casting is also very low.Particularly in traditional centrifugal casting, the runner of centrifuge is perpendicular to the injection molding that waters of centrifuge mostly, invents into the tilting runner through technological improvement afterwards.But no matter be to tilt or vertical stratification, because the mould diameter of large-scale workpiece is far longer than die length, in casting process, copper water directly flows to from runner and waters in the injection molding, in toppling over copper water process, because copper water forms reverse flow, then could under action of gravitation, enter and water injection molding.But in this process, copper water cools off rapidly, and increases water absorption, when formed product, forms cold shut, hole etc. between the copper water, causes retainer that pore, pipe etc. are arranged.The cast copper percent defective is high especially, has a strong impact on product quality and production efficiency.Therefore the defective work that produces need to melt down melting again, increases the raw material loss, and production cost is significantly raise, and causes damage to enterprise.
Summary of the invention
Defective in view of the prior art existence, the objective of the invention is to invent a kind of large-scale copper cage cast directed flow funnel device, the present invention has designed a kind of novel cast runner, this runner comprises that two parts form, a part is the inclination sprue, another part be controlling party to the terminal hoppers runner.The runner of this structure can make copper water can be rapidly, the concentrated area enters mould, reduces temperature and reduces amplitude, increases capacity, solved well the casting flaws such as pore, pipe of casting copper band type blank, reduces the cast copper percent defective.
For achieving the above object, the technology used in the present invention solution:
Large-scale copper cage cast directed flow funnel device, comprise baffle plate, sliding tray, runner body, the funnel device of runner terminal, casting mold, it is characterized in that: described baffle plate is fixed in the two ends of runner body, and runner body lower end arranges a sliding tray that can be connected with centrifugal gate; Be divided into three sections below the described runner body, first paragraph is straight portion, and second segment is the drainage targeting part of downward-sloping certain angle, and the 3rd section is runner body terminal part; And at runner body terminal part a funnel device is set.
The described funnel device upper end vertebral body structure that is square, its size is greater than width of flow path; The funnel device lower end structure structure that is square, its size is less than the width of casting mold.
After adopting such scheme, compare with existing product, the technology of the present invention has following beneficial effect:
The baffle plate that the present invention is positioned at the two ends of runner body can prevent splash when the cast of casting copper water; The runner drainage targeting part that tilts play the guiding role to copper water, and copper water is flowed downward; Copper water enters the terminal part of runner, and funnel device puts together copper water, flows directly to the casting mold inwall, and the copper water that do not have oppositely, splashes has been avoided the defectives such as blow hole, pipe, enhances productivity.
Description of drawings
Fig. 1 is structural representation sketch of the present invention;
Fig. 2 is structural representation top view of the present invention;
Fig. 3 is funnel device and casting mold structural representation sketch.
Among the figure: 1, baffle plate, 2, sliding tray, 3, the runner body, 3a, straight portion, 3b, drainage targeting part 3c, terminal part, 4, funnel device, 5, casting mold, 6, centrifuge, 7, be connected and fixed device.
The specific embodiment:
Further specify technical scheme of the present invention below in conjunction with accompanying drawing:
Large-scale copper cage cast directed flow funnel device, as shown in Figure 1, 2, the funnel device 4, the casting mold 5 that comprise baffle plate 1, sliding tray 2, runner body 3, runner terminal, described baffle plate 1 is fixed in the two ends of runner body 3, runner body 3 lower ends arrange one can with 6 sliding trays that are connected 2 of centrifuge; Described baffle plate 1 can prevent splash when adding copper water.
Be divided into three sections below the described runner body 3, first paragraph is straight portion 3a, and second segment is the drainage targeting part 3b of downward-sloping certain angle, and the 3rd section is runner body terminal part 3c; And at runner body terminal part 3c a funnel device 4 is set.The described funnel device 4 upper ends vertebral body structure that is square, its size is greater than width of flow path; The funnel device 4 lower end structure structure that is square, its size is less than the width of casting mold 5.
Described funnel device 4 lower ends are apart from casting mold 5 certain altitudes, can effectively prevent the copper aqueous dispersion and copper water is put together, and become uniform state to be distributed in the casting mold 5.
Described funnel device 4 also can be fixed in the casting mold top by being connected and fixed device 7, as shown in Figure 3.
Instantiation: the hopper walls of funnel device 4 should be higher than runner body riser, when copper water enters funnel by runner, is equivalent to Jiang Tongshui and puts together, and what flow into directly, continuously High Rotation Speed waters the injection molding inwall, and copper water is along the inwall high speed rotary.The part of funnel device 4 upper end connecting passages is called the funnel upper end, the upper end open place is greater than the width of runner, is convenient to copper water and enters, and funnel lower end width is less than 20 millimeters of cast Mould Breadth degree, exit, funnel lower end, apart from 50 millimeters of casting mold 5 inwalls distances, this dimensional structure can guarantee, the unreserved funnel that enters of the copper water of runner, enter the copper water of funnel watering effective inwall workspace flow at high speed of injection molding, reverse flow can not occur, realize copper water cast directed flow.
Invent the Rational structure of this injection copper water, avoided the casting flaw of product, such as pore-free, without slag inclusion, without casting flaws such as pipes, guarantee the castability of retainer product, enhance productivity, improved product quality.
