Abstract
The utility model discloses a special casting head for manufacturing a walking machinery motor cover. The casting head comprises an upper section and a lower section; the upper section is a cylinder with a seal cover on the top and a bottom opened; the lower section type structure is integrally formed by a truncated cone-shaped structure and a cylindrical structure, and the diameter of the cylindrical structure is slightly smaller than the inner diameter of a lower cavity of the upper section type structure; and the connected relation of the upper section and the lower section is that the upper section and the lower section are separated. The casting head is arranged on the front face; and the structure has the advantages that the structure can be suitable for molding lines with small width, and the casting head is designed in a two-section type, so that the casting head can be telescopic when being used, and the impact force of heat is buffered.
Description
Technical field
The utility model relates to a kind of manufacturing walking machine motor cover foundry goods, is specifically related to the special-purpose rising head of this kind manufacturing walking machine motor cover casting usefulness.
Background technology
The technology of sand mold iron castings is just popular from B.C. Han dynasty in China, and even to this day, cast member has been improved to by traditional extensive foundry goods has meticulous runner, and casting quality can effectively cooperate the requirement of automation control foundry goods.In the process of whole reform, technical mainly is that the composite of precoated sand researched and developed, and on the shape and structure of precoated sand shell, generally all is that the imitative type structure of foundry goods outline of the full precoated sand material of employing adds rising head then.But general precoated sand shell all is special-purpose moulding casing realizes moulding, can not be applicable to general moulding streamline.In order to adapt to general moulding streamline, my company has now improved a kind of special-purpose precoated sand shell of making the walking machine motor cover that is applicable to.This shell has the little feature of volume, still, because therefore the feature of small size will carry out the design of rising head at the patrix of motor cover.But up to the present, there is not bibliographical information correlation technique content.
Summary of the invention
Main task of the present utility model is to provide a kind of particular manufacturing craft rising head of making walking machine motor cover foundry goods, and this rising head has the function that anti-foundry goods shrinks.
In order to solve above technical problem, the special-purpose rising head of a kind of manufacturing walking machine motor cover of the present utility model, its innovative point is: described rising head is the two sections formula,
The described segmentation structure that goes up is: top band capping, the cylinder that the bottom is uncovered; Described cylindrical capping is provided with a centre hole, and described cylindrical cavity divides two sections, and the epimere cavity diameter is less than the hypomere cavity diameter, and the epimere wall thickness is greater than the hypomere wall thickness, and last hypomere cavity boundary forms hierarchic structure;
Described segmentation down is that truncated cone-shaped structure and cylindrical structural global formation constitute, and the diameter of described cylindrical structural is the internal diameter that is slightly less than hypomere cavity in the segmentation structure; The equidistant reinforcement that is provided with radially of the periphery of described cylindrical structural, the terminal global formation of described truncated cone-shaped structure has the insertion leg.
The annexation of described two sections formula structure: the two sections formula is isolating construction, built-in insertion leg in the hypomere cavity of last segmentation, and the built-in degree of depth to reinforcement withstands cavity lower edge, lower end.
Advantage of the present utility model is: adopt this rising head, the walking machine motor cover just can will face up when making, establish dead head in the front, the advantage of this structure is to adapt to the less mo(u)lding line of width, and, this dead head two-piece design, the rising head that makes can stretch in use, the impulsive force of buffering heat; Also have, the advantage of thickening at last segmentation Feeder Design inner chamber ladder is effectively to guarantee the temperature of cavity, is strictly on guard against heat radiation.Also have, this process using blank sheet of paper is done isolation, has reduced in rising head installation and the use to produce broken sand because stretching, and stops to influence the hidden danger of casting quality.

The specific embodiment
The special-purpose rising head of a kind of manufacturing walking machine motor cover of the present utility model, structure be as shown in Figure 1: rising head is last segmentation rising head 1 and following segmentation rising head 2.The two sections formula is isolating construction.
Last segmentation rising head 1 structure is as shown in Figure 2: going up segmentation rising head 1 is top band capping 3, the cylinder that the bottom is uncovered; Capping 3 is provided with a centre hole 5, last segmentation rising head 1 inner chamber wall thickness is notch cuttype and divides two sections to be illustrated as epimere cavity 6 and hypomere cavity 7, epimere cavity 6 diameters are less than hypomere cavity 7 diameters, and namely epimere cavity 6 wall thickness are greater than hypomere cavity 7 wall thickness, and last hypomere cavity boundary forms hierarchic structure; Last segmentation rising head is the precoated sand global formation.
Shown in Fig. 2,3, following segmentation rising head 2 is that truncated cone-shaped cylinder 8 and cylindrical column 9 global formations constitute.The diameter of cylindrical column 8 is the internal diameter that is slightly less than hypomere cavity 7 in the segmentation structure; The equidistant reinforcement 10 that is provided with radially of the periphery of cylindrical column 9, the terminal global formation of described truncated cone-shaped cylinder 8 has some insertion legs 11 that distribute that all occupy, described insertion leg 11 is circumferential distribution along the end of truncated cone-shaped cylinder 8, the equal diameters of the circle diameter that surrounds and truncated cone-shaped cylinder 8.During use, insert leg 11 and insert in the lower end cavity 7, the end of reinforcement 10 just in time props up the lower edge of lower end cavity 7, makes that going up segmentation rising head 1 connects together with following segmentation rising head 2.
During use, shown in Fig. 3,4, the precoated sand shell that is equipped with the loam core is placed in the mo(u)lding line 9a, cover moulding cover plate 10a, establish the riser runner 12 that communicates with the overlay film sandbox at cover plate plate face then, wait to overlap riser runner 12 places at cover plate plate face and lay a blank sheet of paper 16, will descend segmentation rising head 2 to set up across blank sheet of paper 16 then, be communicated with the overlay film sandbox, on cover plate plate face, plug air-out needle 13 at the venthole place that reserves again.Then at the molten iron that pours into 1380 ℃ temperature by rising head, 8-10 second duration of pouring, in 1-1.5 hour, realize cooling then.This pouring technology is conventional, mainly is to adopt the instrument of said structure to realize that this conventional technology reaches effect preferably.
Effect 1: use above-mentioned instrument, can effectively adapt to the production operation that various sizes are less than normal, the place is tight slightly;
Effect 2: between rising head and mould board, add isolation, avoid broken sand.
Effect 3: adopting this device, is that the front casting mold of motor cover foundry goods is done patrix during cast, does not need to be inverted, and reduces the place usable floor area of cast.
Effect 4: adopt this rising head, effectively reduce the rising head volume, and because this rising head is the fever type rising head, have the feature of high insulating effect, reduce shrinkage factor.
