Abstract
The utility model relates to a centrifugal casting mould of cylinder jacket rough of a combustion engine, comprising a mold body connected with a principal axis of a centrifugal casting machine, a back blocking block of the mold body connected with a mandril of the centrifugal casting machine and a front cover. The utility model is characterized in that a sand mold jacket is positioned inside the mold cavity of the mold body. The external surface of the cylinder jacket rough of the combustion engine cast by the centrifugal casting mould is not with a white iron hardened layer; the external surface is bright and clean; the utility model is of large and even volume density and good quality, the mechanical manufacturing of finished products can be carried out without high temperature retreat, thus saving the working hour and the production cost.
Description
Technical field
The utility model relates to mold, is a kind of bad mould for centrifugal casting of cylinder of internal combustion engine toison.
Background technology
Existing cylinder of internal combustion engine cover blank is an alloy cast iron blank, and it is to adopt the mould for centrifugal casting moulding, because the die cavity of mould is metal pattern build chamber, the sand mold cover is not set in the die body die cavity.Use the cylinder of internal combustion engine toison blank outer surface of this die casting that the white iron hardened layer is arranged, must just can carry out machining through high annealing, exist time-consuming, the high deficiency of manufacturing cost.
Summary of the invention
The purpose of this utility model is to provide a kind of cylinder of internal combustion engine cover blank not need high annealing just can carry out machining, low cost of manufacture, the blank outer surface is bright and clean, and volume density is big and evenly, the measured cylinder of internal combustion engine of matter overlaps the blank mould for centrifugal casting.
The utility model is realized by following technical scheme: a kind of cylinder of internal combustion engine cover blank mould for centrifugal casting, it comprises the die body that is connected with the centrifugal casting machine main shaft, with stifled behind the die body that the centrifugal casting machine push rod is connected, protecgulum, its special character is: the die cavity at die body is built-in with the sand mold cover.
Cylinder of internal combustion engine cover blank mould for centrifugal casting of the present utility model, because this mould has at the die body die cavity and is built-in with the sand mold nested structure, the bad outer surface of casting of cylinder of internal combustion engine toison does not have the white iron hardened layer, outer surface is bright and clean, volume density is big and evenly, quality is good, does not need high annealing just can carry out machining and makes finished product, saving of work and time, low cost of manufacture.
Description of drawings Fig. 1 is a structural representation of the present utility model.Fig. 2 is half sand mold cover schematic diagram among Fig. 1.Fig. 3 looks schematic diagram for the left side of Fig. 2.
The specific embodiment
The utility model is described in further detail to utilize embodiment shown in the drawings below.
With reference to Fig. 1, stifled 3 behind the die body 1 of cylinder of internal combustion engine cover blank mould for centrifugal casting, the die body, protecgulum 6 all adopts metal material to make.Die body 1 is connected with centrifugal casting machine main shaft 2 by flange, and back stifled 3 of die body 1 is threaded with push rod 4 in centrifugal casting machine main shaft 2 endoporus, is built-in with sand mold at the die cavity of die body 1 and overlaps 5, and protecgulum 6 is connected with die body 1 front end by screw.
With reference to Fig. 1-3, sand mold cover 5 is the two halves structure.Sand mold cover 5 adopts foundry sand to make through metal die.
