Abstract
The utility model discloses a kind of diesel engine machine frame casting mould, it is characterised in that：The mold includes mold（1）, in mold（1）Top be evenly equipped with multiple waste chambers（2）, and these waste chambers（2）Mold（1）Inner cavity be connected, all waste chambers（2）Total measurement (volume) be mold（1）The 5 10% of total measurement (volume)；The waste chamber（2）For cylindric or cubic.This is that one kind is simple in sturcture, ingenious in design, rationally distributed, on the premise of can having high intensity and hardness ensureing casting, the diesel engine machine frame casting mould still with excellent processing performance.
Description
Technical field
The utility model is related to engine manufacturing fields, particularly a kind of diesel engine machine frame casting mould.
Background technology
When carrying out the production of diesel engine machine frame, high trade mark gray cast iron is selected first（HT350）It is cast as raw material
Go out blank, it is then machined to be used cooperatively afterwards with cylinder block, and bent axle is fixed between cylinder body and frame, due to
Frame belongs to the critical component of very core within the engine, therefore very high to the quality requirement of frame.First, frame will have
High intensity and hardness, to ensure the performance of frame and service life；Secondly, frame will ensure very high in mechanical processing
Dimensional accuracy and geometric tolerance.Two above mass property just determines that frame will have on the premise of with high intensity and hardness
There is excellent processing performance.But under normal conditions, for hardness with processability there are certain contradiction, hardness height often means that processing
Property be deteriorated.
If using traditional casting technique and mold, wanted although the intensity and hardness of the casting produced can meet
It asks, but its processing performance is very poor, in mechanical processing, tool wear is serious, efficiency declines, dimensional accuracy can not ensure, product
Uniformity is poor.Expect that the serious casting of hard situation can only directly be scrapped, product rejection rate caused by due to expecting firmly reaches 8%~10%.
Therefore need one kind being capable of solution to the problems described above or device now.
The content of the invention
The utility model is to solve the above-mentioned deficiency present in the prior art, proposes that one kind is simple in structure, design is skilful
It is wonderful, it is rationally distributed, on the premise of can having high intensity and hardness ensureing casting, the still bavin with excellent processing performance
Oil turbine frame casting mould.
The technical solution of the utility model is：A kind of diesel engine machine frame casting mould, it is characterised in that：It is described
Mold include mold 1, be evenly equipped with multiple waste chambers 2 at the top of mold 1, and the inner cavity of each waste chamber 2 with
It is connected between the inner cavity of mold 1, the total measurement (volume) of all waste chambers 2 is the 5-10% of 1 total measurement (volume) of mold.
The waste chamber 2 is cylindric.
The waste chamber 2 is cubic.
The utility model compared with the existing technology, has the following advantages that：
The diesel engine machine frame casting mould of this kind of structure type compared with traditional mold, increases at the top of mold
Multiple waste chambers communicated with its inner cavity are added, a part of molten iron allowed in casting process is filled into waste chamber at first, is utilized
The mode of a part of material is sacrificed to delay the cooling velocity of molten iron and time in dies cavity, is avoided in workpiece surface because of molten iron
The too fast carbide for being cooled into influencing processing performance, and after the casting is completed, then using mach mode by waste material
It removes the part of the cementite generated in chamber.This mold can allow the product quality of cast member to be obviously improved, and reduce waste product
Loss, therefore with more significant economic benefit.
Description of the drawings
Fig. 1 is the structure diagram of the utility model embodiment.
Specific embodiment
Below in conjunction with description of the drawings specific embodiment of the present utility model.As shown in Figure 1：A kind of diesel engine machine frame
Frame casting mould, it includes the mold 1 based on one, the bavin that the shape of this 1 inner cavity of mold is cast as needed
The concrete structure of oil turbine frame is designed, and multiple waste chambers 2 are evenly distributed at the top of this mold 1, and
Each it is connected between the inner cavity of waste chamber 2 and the inner cavity of mold 1, while the total measurement (volume) of all waste chambers 2 accounts for mold 1
Total measurement (volume) 5-10%；Waste chamber 2 can make choice or design according to the concrete structure at 1 top of mold, as waste chamber 2 needs
Be connected on the round table-like part at the top of mold 1, then waste chamber 2 can be designed as it is cylindric, as waste chamber 2 needs to connect
It is connected on the rectangle part at 1 top of mold, then waste chamber 2 can be designed as cubic；No matter how waste chamber 2 sets
Meter, principle are that the part molten iron entered at first in 1 inner cavity of mold uniformly can be introduced into multiple waste chambers 2.
There are a molten iron type to be filled at first cold when carrying out the casting of diesel engine machine frame using traditional moulds, in mold
But and the region that solidifies, since the setting rate of this partial molten iron is fast, it can cause occur cementite in microstructure, and cementite
Characteristic be hard and crisp, be unfavorable for machining；
Using the utility model embodiment casting mould carry out diesel engine machine frame casting when, molten iron can first on
It moves in the multiple waste chambers 2 added, and due to persistently there is the molten iron of overheat guarantor at the part that waste chamber 2 is connected with dies cavity
It holds, therefore speed and the time of molten iron cooled and solidified can be delayed, occur influence processing performance when avoiding solidification in casting
Cementite, and the solidification that takes the lead in, the part in waste chamber 2 be although unfavorable for processing, but required for being not belonging to due to it
Product a part, therefore can be removed in the casting cleaning in later stage,
The total measurement (volume) of all waste chambers 2 accounts for the 5-10% of 1 volume of mold, and this design can both ensure to have enough
The molten iron being quickly cooled down can enter waste chamber 2, and can prevent the waste for raw material.
