Abstract

The invention discloses a die for casting a crankcase. The die for casting the crankcase comprises an outer die, an inner cavity and a bearing pedestal, wherein the outer die is enclosed by metal side dies and a metal bottom die; the inner cavity is formed by a main body core and an insert; preferably, the metal bottom die has a multi-boss structure; the inserts are commonly positioned through the bottom die and the main body core; and the bearing pedestal is arranged downwards on the bottom die. The invention also discloses a method for casting the crankcase. The method for casting the crankcase comprises the following steps of: enclosing four metal side dies and the metal bottom die to form the outer die; arranging the bearing pedestal downwards on the bottom die; placing the pre-manufactured insert into a positioning groove corresponding to the metal bottom die and placing the main body core to position and fix to manufacture the inner cavity; and casting the crankcase by a turnover gravity casting method. By a device and the method for casting the crankcase disclosed by the invention, finished product ratio and production efficiency are effectively improved in the process of casting a diesel aluminum alloy crankcase, parts of which are embedded with metals with different materials.

Description

A kind of casting mould of crankcase and method
Technical field
The present invention relates to a kind of casting mould and method of crankcase, particularly a kind of casting mould and method of diesel engine aluminium alloy crankcase.
Background technology
At present, the domestic diesel engine aluminium alloy crankcase casting field of inlaying different metals in the part, because local complexity and the intrinsic characteristic of different metals of inlaying the diesel engine aluminium alloy crankcase casting of different metals, the difficulty that the diesel engine aluminium alloy crankcase that makes the part inlay different metals is cast is very big.Produce both at home and abroad similar foundry goods, aluminium alloy gasoline engine for example, the employing high-pressure casting that has, the full sand mold gravitational casting of the employing that has, and be aided with the water pipe cooling means and produce, the casting wasted product rate of being produced is very high, and production efficiency is lower, does not far reach enterprise's requirement.If in casting process, adopt the water pipe cooling, very big potential safety hazard arranged.
Summary of the invention
The purpose of this invention is to provide a kind of crankcase casting mould and method, inlay the low problem of percent defective in the diesel engine aluminium alloy crankcase casting of different metals to solve in the part.
In order to realize above purpose, the invention discloses a kind of crankcase casting mould, comprise external mold and inner chamber, external mold is surrounded by metal side form and metal bed die, and inner chamber is formed with inserting by main body sand core.
Preferably, bed die adopts many boss structures; Insert and locate jointly by bed die and main body sand core; Comprise bearing block, bearing block is arranged on the bed die down.
The invention also discloses a kind of crankcase casting method, adopt crankcase casting mould disclosed by the invention, may further comprise the steps: metal side form and a metal bed die are surrounded an external mold, and bearing block is arranged on the metal bed die down; Previously prepared inserting is arranged in the locating slot of bed die correspondence, places main body sand core positioning and fixing in addition again, make inner chamber; Adopt convertible gravitational casting that crankcase is poured into a mould.
Crankcase casting device disclosed by the invention and method have effectively improved the yield rate and the production efficiency of inlaying in the part in the diesel engine aluminium alloy crankcase casting of different metals.

The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.
Shown in Fig. 1-5, the embodiment of the invention 1 provides a kind of crankcase casting mould, external mold leaves metal pattern by five and constitutes, comprise first side form 1, second side form 2, the 3rd side form 3, the 4th side form 4 and bed die, bed die 5 is the structure of many boss 9, as shown in Figure 2, the inner chamber of external mold is by main body sand core 6 and insert and 7 form, as shown in Figure 3, insert 7 by main body sand core 6 and bed die 5 stationary positioned, insert 5, main body sand core 6 constituted the casting cavity with the cavity that metal pattern surrounds, and also is provided with bearing block 8 on the bed die, bearing block 8 is provided with down.Be fixed on bed die earlier because needing inserts bearing block earlier, traditional bearing block can't be realized up, so adopt bearing block mode down.
This crankcase casting device adopts five karat golds to belong to mode structure, with respect to the sand mold mould, and good cooling results not only, the surface of foundry goods is very attractive in appearance, and surface quality is very desirable; Adopt bed die and the main body sand core positioning and fixing of will inserting jointly, the accurate location in casting process of having guaranteed to insert prevents to move, and improves the workman simultaneously and places the operation of inserting, and has alleviated the labour intensity when producing; Bed die is made many boss structures, changes local cooled and solidified order, need to guarantee the position of feeding to obtain fully effectively feeding, makes the casting wasted product rate of production be controlled in the desirable scope production efficiency height.
The embodiment of the invention 2 provides the method for the crankcase casting mould march axle box casting of a kind of embodiment of employing 1, and concrete grammar is as follows: four metal side forms and a metal bed die are constituted an external mold, and bearing block is arranged on the metal bed die down; Previously prepared inserting is placed in the locating slot of bed die correspondence, places main body sand core stationary positioned in addition again; Adopting convertible gravitational casting that crankcase is poured into a mould gets final product.
This crankcase casting method adopts the five die sinkings structure of signing an undertaking, and helps guaranteeing the presentation quality of crankcase; Bearing block is provided with down, has realized the test manufacture and the production of crankcase; Bed die adopts many boss structures, helps improving aluminium liquid and solidify order in casting process, is convenient to the demoulding; Bed die and the main body sand core stationary positioned of will inserting jointly, accurate location in casting process has guaranteed to insert.
More than disclosed only be several specific embodiment of the present invention, still, the present invention is not limited thereto, any those skilled in the art can think variation all should fall into protection scope of the present invention.
