Abstract
The invention relates to a combined mold for an extra-large casting and forging, and belongs to the technical field of large casting molds. A main body is a wooden barrel with a regular shape; an additional part is a part for manufacturing the extra-large casting and forging in a required shape by using lost foam and is arranged on the main body barrel according to the shape of an extra-large workpiece to be cast and forged; the combined mold is arranged in a hollow box consisting of a left part and a right part; half of resin sand is poured outside a left side combined mold body in the box, and the combined mold is pulled out after the left side resin sand is molded; resin sand is poured outside a right side combined mold body in the box, and the combined mold is pulled out after the right side resin sand is molded, so that two shapes of the combined mold, which are mutually matched and consist of the resin sand are manufactured; and the two shapes of the combined mold are combined together. All parts of the combined mold can be freely disassembled and assembled, and are recycled, cost is saved, and efficiency is improved.
Description
Technical field
The present invention relates to ultra-large type forge piece sectional die, belong to massive casting technical field of mold.
Background technology
Production ultra-large type forge piece is generally by the method for casting of molten metal at present, and this just need to have the mould of ultra-large type forge piece.The mould general structure of this ultra-large type forge piece is complicated, makes difficulty, and when workpiece casting has been forged, molding and workpiece come off and be not easy to control, and therefore usually causes forge piece finished product defective and affect production.
Summary of the invention
Defect in view of prior art exists, the object of this invention is to provide a kind of convenient disassembly, can freely assemble and the molding workpiece that comes off is easy to ultra-large type forge piece sectional die.
For achieving the above object, the technology used in the present invention solution is: ultra-large type forge piece sectional die, main body is the wooden cylindrical shell of regular shape, the parts that optional feature is the ultra-large type forge piece required form made with evaporative pattern, according to the shape that will cast the ultra-large workpiece of forging, optional feature is installed in body barrel, then this assembling die is placed in to one by empty van dimerous of left and right, first to external half resin sand of first pouring into of left group mould in chest, after the resin sand sizing of left side, assembling die is extracted out, and then to the external resin sand that falls of the right group mould of chest, after the sizing of right side resin sand, assembling die is extracted out, make the shape of two assembling dies that formed by resin sand of working in coordination, together by the combination of shapes of these two assembling dies finally.
The present invention adopts assembling die to cast and forges superhuge workpiece, not only can combine various superhuge assembling dies, and the de-part of molding is all than being easier to, and all parts of assembling die can freely be dismantled and assemble, realize recycling, saved cost, improved efficiency.
Accompanying drawing explanation
Fig. 1 is ultra-large type forge piece sectional die structural representation.
In figure: 1, cylindrical shell, 2, evaporative pattern, 3, chest, 4, left side resin sand, 5, right side resin sand.
The specific embodiment
Ultra-large type forge piece sectional die as shown in Figure 1, main body is the wooden cylindrical shell 1 of regular shape, the parts that optional feature is the ultra-large type forge piece required form made with evaporative pattern 2, according to the shape that will cast the ultra-large workpiece of forging, evaporative pattern 2 is installed in body barrel 1, then this assembling die is placed in to one by 3 li of left and right empty van dimerous, first to external half resin sand of first pouring into of the interior left group mould of chest 3, after the 4 sand sizings of left side resin, assembling die is extracted out, and then to the external resin sand that falls of the right group mould of chest, after 5 sizings of right side resin sand, assembling die is extracted out, make the shape of two assembling dies that formed by resin sand of working in coordination, together by the combination of shapes of these two assembling dies finally.
