Abstract
The invention relates to an eight-box split casting process, which is mainly used for casting various engine bodies or machine parts with comparatively complex structures. The process comprises the steps of manufacture of a sand box, molding, casting and sand dropping, and is characterized in that the sand box consists of eight box bodies including an upper box, a lower box, and a front box, a back box, a left box and a right box positioned between the upper box and the lower box, wherein the left box is divided into a left upper box and a left lower box, and the right box is divided into a right upper box and a right lower box; and each core piece inside the sand box is connected and positioned with a box body nearby through a core head. Because the sand box consists of eight parts and each core piece inside the sand box can be positioned with the box body nearby through the core head, the core pieces are mutually independent and do not rely on each other or cause larger accumulated errors, the core pieces are positioned accurately, and the eight-box split sand box is quite convenient and easy to operate in the molding step, so the process saves time and labor, has high working efficiency and low labor intensity, and reduces the production cost of forged pieces.
Description
Technical field
The present invention relates to a kind of casting technique, particularly a kind of eight casees multiple casting technologies are mainly used in the comparatively complicated airframe components of all kinds of engine bodies of casting or other structure.
Background technology
The engine body structure is very complicated, and as the 16V265H diesel engine body of V-structure, oil pipe is the bushing pipe casting, and casing bore, camshaft hole, the horizontal relative size of bolt of drawing require very strict.Appearance and size is 4500*1480*1390mm, thickness 128mm, thinnest part 16mm.Animal economy casting technique difficulty is very big.The mode of nowel moulding and folded case core assembly on the conventional cast process using, the foundry goods that will finish through N Reference Alignment repeatedly, with the process of core assembly is to guarantee the dimensional accuracy of body and requirement on machining accuracy, and cast product is often occurred than mistake on physical dimension.
Utilizing the 16V265H diesel engine body of the localization method casting V-structure of core assembling technology, is to rely on core print that fuse is fixed on the position of regulation.Because the gap value that must exist and the influence of operate miss, be positioned at the deviation that 1 layer chipware can produce 2～3mm, and 2 layers chipware is the benchmark location with 1 layer of chipware, 2 layers of deviation that can produce 4～6mm, and 3 layers chipware is the benchmark location with 2 layers chipware, so 3 layers of deviation that can produce 8～12mm.The shortcoming that this technology also has to waste time and energy, labour intensity is big, efficient is low, make troubles for the postorder machined.
Summary of the invention
The purpose of this invention is to provide a kind of chipware location comparatively accurately, little, the processing ease of error, labour intensity is low, production efficiency is high eight casees multiple casting technologies, overcome the deficiencies in the prior art.
Eight casees multiple casting technologies of the present invention, be made up of following steps: sandbox is made; Moulding; Casting; Knockout; It is characterized in that: described sandbox is formed by eight box body combinations, comprise top box, nowel, the front side case between top box and nowel and rear side case and left side case and right side case, described left side case is divided into left side top box and left side nowel, and the right side case is divided into right side top box and right side nowel; Each chipware that is positioned at the sandbox inboard all is connected the location with wherein casing nearby by core print.
Eight casees multiple casting technologies of the present invention are positioned at the sandbox inboard by means of three-dimensional coordinate and support member with chipware in the wherein said step of overall modelling.
Eight casees multiple casting technologies of the present invention, because sandbox is combined by eight parts, each chipware in it can be located with casing nearby by core print, separate between each chipware, the situation that do not interdepend can not produce big cumulative errors, the chipware accurate positioning, it is very convenient in step of overall modelling to split the pattern sandbox eight the casees, good operation, time saving and energy saving, the operating efficiency height, labour intensity is low, has reduced the production cost of workpiece.
The specific embodiment
Eight casees multiple casting technologies of the present invention are made up of following steps: sandbox is made; Moulding; Casting; Knockout.
Sandbox is formed by eight box body combinations, comprise above top box, below nowel, front side case and rear side case and left side case and the right side case between top box and nowel.Wherein the left side case is divided into left side top box and left side nowel, and the right side case is divided into right side top box and right side nowel.Using the pin-and-hole that cooperatively interacts to insert mutually with bearing pin between each casing is connected.Because sandbox integral body can be divided into eight parts, and is easy to operate in step of overall modelling.Each chipware that is positioned at the sandbox inboard all is connected the location with wherein casing nearby by core print, and each chipware is not related each other, can not exert an influence, and can not produce cumulative errors.
Concrete shape and structure according to casting workpiece, presumable chipware can't be connected with near casing or tie point causes less and can't locate, can on the sandbox body, select a datum mark to set up three-dimensional system of coordinate as initial point, utilize this work mark system that this chipware is carried out centering, and utilize support member location such as clamp, pole.
Claims (2)
1, a kind of eight casees multiple casting technologies, be made up of following steps: sandbox is made; Moulding; Casting; Knockout; It is characterized in that: described sandbox is formed by eight box body combinations, comprise top box, nowel, the front side case between top box and nowel and rear side case and left side case and right side case, described left side case is divided into left side top box and left side nowel, and the right side case is divided into right side top box and right side nowel; Each chipware that is positioned at the sandbox inboard all is connected the location with wherein casing nearby by core print.
2, eight casees multiple casting technologies according to claim 1 is characterized in that: by means of three-dimensional coordinate and support member chipware is positioned at the sandbox inboard in the described step of overall modelling.
