Detailed Description

Reference will now be made in detail to the present preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to like elements throughout.

In the description of the present invention, it is to be understood that the positional or orientational relationships, such as those indicated by center, longitudinal, lateral, length, width, thickness, upper, lower, front, rear, left, right, vertical, horizontal, top, bottom, inner, outer, clockwise, counterclockwise, axial, radial, circumferential, and the like, are based on the positional or orientational relationships shown in the drawings and are for convenience of description and simplicity of description only, and are not intended to indicate or imply that the device or element so referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus are not to be considered as limiting.

In the description of the present invention, the meaning of several is one or more, the meaning of a plurality is two or more, and larger, smaller, larger, etc. are understood as excluding the present number, and larger, lower, inner, etc. are understood as including the present number unless specifically defined otherwise. Furthermore, the descriptions of first and second are only for the purpose of distinguishing between technical features, and are not to be construed as indicating or implying relative importance or implying any number or order of indicated technical features.

In the description of the present invention, unless otherwise expressly limited, terms such as set, arranged, mounted, connected, fixed and the like should be construed broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in the present invention in consideration of the detailed contents of the technical solutions.

In the description of the present invention, unless otherwise expressly limited, a first feature may be located on or below a second feature in direct contact with the second feature, or the first feature and the second feature may be in indirect contact via intermediate media. Also, a first feature may be directly above or obliquely above a second feature, or merely that the first feature is at a higher level than the second feature. A first feature may be directly below or obliquely below a second feature, or may simply mean that the first feature is at a lesser elevation than the second feature.

Referring to fig. 1 and 2, the cope flask according to the embodiment of the present invention includes a cope flask 11 and a cope platen, the cope flask 11 has a sand shooting passage 12 therein, and a cope platen body 21 moves up and down in the sand shooting passage 12.

In addition, referring to fig. 3, the cope flask platen according to the embodiment of the present invention includes a main body 21, a plurality of sand shooting port plates 31 are mounted on an end surface of a bottom of the main body 21, each sand shooting port plate 31 has a sand shooting hole 32, the main body 21 has a sand outlet 22 communicating with the corresponding sand shooting hole 32, and each sand shooting port plate 31 is made of steel.

The match steel, also known as polyoxymethylene, has very low coefficient of friction and fine geometric stability, and the inventor uses it on the cope flask clamp plate of molding machine, finds that the molding sand is difficult for the adhesion on match steel matter component, if directly replace into the match steel matter with the whole top board body, then top board body intensity is not enough, is difficult to satisfy the requirement of compaction sand mould. Therefore, the sand shooting port plate 31 is designed as a steel member, the sand shooting port plate 31 is a rectangular plate-shaped member, and the sand shooting port plates 31 are arranged adjacently in sequence and are distributed over the bottom end face of the upper platen body 21. So, can guarantee the intensity of top board body 21, the peculiar material performance of usable race steel again to, in the use, if individual shooting mouth board 31 needs to be changed, can change alone, need not to change whole shooting mouth boards 31, cost of maintenance is low.

In this embodiment, the sand shooting port plate 31 is connected to the upper pressure plate body 21 by bolts, bolt holes 33 are formed around the sand shooting port plate 31, and each bolt hole 33 is a counter bore. In other embodiments, the sand shooting port plate 31 may be connected to the upper platen body 21 using other connection means.

In this embodiment, the aperture of the sand outlet 22 is gradually reduced from top to bottom, and specifically, the axial cross section of the sand outlet 22 is in an isosceles trapezoid shape. The sand outlet 22 with the aperture gradually reduced from top to bottom can play a role in guiding molding sand, so that the molding sand can flow into an upper sand box, the aperture gradually narrows to improve the corresponding injection speed, the molding sand collides with a molding die plate, the upper sand box is filled more uniformly, the compactness of the molding sand after molding compaction is uniform, and the finished product rate of poured products is improved.

While the embodiments of the present invention have been described in detail with reference to the drawings, the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
