Abstract
The utility model relates to an inclining mold cavity of a poured bearing plate, comprising a straight pouring channel, an upper sand mold, a bearing plate, a transverse pouring channel, a lower sand mold and a wedged sand cushion. The right end of a bearing plate mold cavity is lifted by using the wedged sand cushion, so that the bearing plate mold cavity inclines and is poured at a high end; the inclining mold cavity increases the height of an effective static head of a molten iron liquid level and the flow speed, so that the mold cavity is quickly filled with molten iron, the time of baking a mold cavity wall by high temperature molten iron is reduced, the defects of sand inclusion, scabbing and cold shut on a bearing plate cast are overcome, and the casting quality of the bearing plate is improved.
Description
Technical field
The utility model relates to a kind of casting technique, especially pours into a mould the inclination die cavity of supporting plate.
Background technology
Pour into a mould at present the die cavity of supporting plate, can not edge-on Jiao with in the situation of Vertical upright casting, adopt die cavity horizontal direction cast supporting plate, because the die cavity wall is toasted by high temperature liquid iron for a long time, burning into sand occurs at the supporting plate foundry goods, scab and the defective of cold shut, have a strong impact on the supporting plate quality or cause and scrap.
Summary of the invention
The utility model provides a kind of inclination die cavity of pouring into a mould supporting plate, with wedge shape sand pad supporting plate die cavity right-hand member is raised and the supporting plate die cavity to be tilted and pour into a mould high-end, the die cavity that tilts improves the effective hydrostatic head height of molten iron level and flowing velocity makes molten iron be full of fast die cavity, reduce high temperature liquid iron to die cavity wall stoving time, improved the supporting plate castability.
The technical scheme that its technical problem that solves the utility model adopts is: be comprised of sprue, upper sand mold, supporting plate, cross gate, ingate, lower sand mold and wedge shape sand pad.Supporting plate, ingate are located at lower sand mold, and cross gate, sprue are located at sand mold; Upper sand mold and lower sand mold get togather and are placed on behind the type on 25/100 the wedge shape sand pad that the difference in height that makes supporting plate inclination die cavity right-hand member raise aspect ratio supporting plate inclination die cavity left end with moulding sand being fit to of making accounts for the supporting plate length of side.
The beneficial effects of the utility model: use cast supporting plate inclination die cavity, overcome supporting plate foundry goods burning into sand, scabbed and the defective of cold shut.The inclination die cavity of using the cast supporting plate has improved supporting plate casting qualification rate 40%.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Accompanying drawing is the longitudinal sectional view of the inclination die cavity of cast supporting plate.
Fig. 1 is front view.
Among the figure 1, sprue, 2, upper sand mold, 3, cross gate, 4, ingate, 5, supporting plate, 6, lower sand mold, 7, wedge shape sand pad.
The specific embodiment
Accompanying drawing is the longitudinal sectional view of the inclination die cavity of cast 30 molding box formula electric furnace supporting plates.In the accompanying drawings, being provided with the length of side at lower sand mold (6) is that 800mm, average wall thickness are that 20mm, weight m are 30KW.h molding box formula electric furnace supporting plate (5) and two ingates (4) of 92.2kg; Upper sand mold (2) is provided with cross gate (3), sprue (1); The upper sand mold (2) and lower sand mold (6) of 30KW.h molding box formula electric furnace supporting plate (5) have been made with the ramming of ZGS80-30H-15 green sand, for improving the effective static pressure height of liquid level and the flowing velocity of molten iron, be placed on behind upper sand mold (2) and lower sand mold (6) mould assembly on 25/100 the wedge shape sand pad (7) that the difference in height that makes 30KW.h molding box formula electric furnace supporting plate (5) inclination die cavity right-hand member raise aspect ratio 30KW.h molding box formula electric furnace supporting plate (5) die cavity left end with ZGS80-30H-15 green sand being fit to of making accounts for 30KW.h molding box formula electric furnace supporting plate (5) the die cavity length of side, 30KW.h molding box formula electric furnace supporting plate (5) die cavity right-hand member raised made the inclination of 30KW.h molding box formula electric furnace supporting plate (5) die cavity; 30KW.h the high-end difference in height than 30KW.h molding box formula electric furnace supporting plate (5) inclination die cavity left end low side of molding box formula electric furnace supporting plate (5) inclination die cavity right-hand member equals 25/100 * 800=200 (mm), calculating empirical coefficient s the duration of pouring is molten iron casting time in 2.0,30KW.h molding box formula electric furnace supporting plate (5) the inclination die cavity
30KW.h the minimum rate of climb of molten iron level=h/t=200/19.2 ≈ 10.4 (mm/s) in molding box formula electric furnace supporting plate (5) the inclination die cavity, the minimum rate of climb 10.4mm/s of molten iron level meets the requirement of the minimum rate of climb 10-20mm/s of molten iron level in 30KW.h molding box formula electric furnace supporting plate (5) the inclination die cavity.Melted heat-resisting cast iron RTSi5 material molten iron is poured sprue (1), molten iron is full of 30KW.h molding box formula electric furnace supporting plate (5) inclination die cavity fast from the high-end beginning of right-hand member after entering cross gate (3) and two ingates (4) in 30KW.h molding box formula electric furnace supporting plate (5) inclination die cavity, reduced high temperature liquid iron to die cavity wall stoving time, overcome the burning into sand of 30KW.h molding box formula electric furnace supporting plate (5) foundry goods, scab and cold shut defects, the inclination die cavity of using cast 30KW.h molding box formula electric furnace supporting plate (5) has improved the casting qualification rate of 30KW.h molding box formula electric furnace supporting plate (5) foundry goods.
Claims (1)
1. an inclination die cavity of pouring into a mould supporting plate is comprised of sprue, upper sand mold, supporting plate, cross gate, ingate, lower sand mold and wedge shape sand pad, and it is characterized in that: supporting plate, ingate are located at lower sand mold, and cross gate, sprue are located at sand mold; Upper sand mold and lower sand mold get togather to be placed on behind the type with moulding sand and make on 25/100 the wedge shape sand pad that the difference in height that is fit to make supporting plate inclination die cavity right-hand member raise aspect ratio supporting plate inclination die cavity left end accounts for the supporting plate length of side.
