Abstract
The utility model relates to a high-temperature alloy bend investment casting mold which comprises a bend shell which is vertically placed, wherein the opening ends of the bend shell are downward and horizontally arranged; an annular pouring gate is arranged in each of the two opening ends of the bend shell and is provided with an annular narrow-gap sprue which is communicated with a bend forming cavity of the bend shell; the annular pouring gates are communicated with a vertical pouring gate through horizontally arranged nonlinear pouring gates; a spherical casting head communicated with the bend forming cavity of the bend shell is arranged at the upper part of the bend shell. In cooperation with the annular pouring gates with the annular narrow-gap sprues by adopting the horizontally arranged nonlinear pouring gates, conveying and pouring processes of molten steel from the vertical pouring gate to the bend shell can be completed, and the high-temperature alloy bend investment casting mold has a simple structure, is convenient to pour, can effectively solve the problems of poor surface quality, poor gas tightness and groove part loosening, and improves the pouring quality.
Description
Technical field
The utility model relates to casting technology field, is a kind of mould of model casting high temperature alloy bend pipe specifically.
Background technology
The casting method of high temperature alloy bend pipe is not very ripe at home always, is exploring feasible effective ways in industry always.The sand casting that tradition adopts, the high temperature alloy bend pipe surface quality that casts out is poor, poor air-tightness, groove position are loose, and mostly need to carry out repair welding could be up to standard, and its yield rate is low, and production cost is high.And when the bend pipe assembly welding chemical industry after repair welding is up to standard is used radiant tube, affect service life and the security performance of radiant tube.
Summary of the invention
For deficiency of the prior art, it is a kind of simple in structure that the utility model provides, and cast is convenient, can solve effectively that surface quality is poor, poor air-tightness, the loose problem in groove position, improves the high temperature alloy bend pipe investment casting mold of casting quality.
The technical solution adopted in the utility model is: a kind of high temperature alloy bend pipe investment casting mold, comprise a vertical placement and nose end horizontally disposed bend pipe shell down, it is characterized in that: two nose ends of described bend pipe shell are provided with ring gate, ring gate is provided with the thin gap of annular design cast gate, the thin gap of annular design cast gate is communicated with the forming elbow chamber of bend pipe shell, ring gate is communicated with vertical running channel through horizontally disposed non-rectilinear running channel, and the top of bend pipe shell is provided with a spherical cap mouth that is communicated with bend pipe shell forming elbow chamber.
Further, described non-rectilinear running channel is that arc running channel or Multi-arc type form snakelike running channel.
Further, be socketed with annular chill on the nose end outer wall of described bend pipe shell.
Further, described thin gap of annular design cast gate is the 1/3-1/5 of bend pipe shell forming elbow chamber thickness.
Adopt technique scheme, the beneficial effects of the utility model are: be horizontally disposed with the non-rectilinear running channel in the vertical lower end of running channel, molten steel enters arc or snakelike running channel by vertical running channel, and being conducive to molten steel, to fill type steady; Molten steel is delivered to ring gate by the non-rectilinear running channel, can stop that in ring gate field trash enters the forming elbow chamber; Ring gate is sent molten steel into the forming elbow chamber by the thin gap of annular design cast gate, the thin gap of annular design cast gate is less than forming elbow chamber thickness, forming elbow chamber molten steel is sent into stable, effectively solves not uniform thickness, yielding problem that the alloy bend pipe produces in casting process because wall thickness is thinner; Bend pipe shell port overcoat T-Ring shape chill is controlled and is entered the lower pouring temperature of forming elbow chamber molten steel, and the first crystallization in bottom, forming elbow chamber makes the groove part bit organization fine and close, can avoid crackle, shrinkage defect occurring near ingate; At alloy bend pipe top, the spherical cap mouth is set, effectively prevents the generation of blow hole.
The utility model adopts horizontally disposed non-rectilinear running channel to coordinate with the ring gate of thin gap of annular design cast gate and completes molten steel by the conveying cast of vertical running channel to the bend pipe shell, it is simple in structure, cast is convenient, can solve effectively that surface quality is poor, poor air-tightness, the loose problem in groove position, improve casting quality.
