Abstract
The present invention discloses a kind of chill and is easy to place the core design method and chill laying method of chill, the chill is formed by the filling of multiple steel shots, can not only chilling action be played to casting, and as core is defeated and dispersed together when unpacking, it will not remain in casting chamber, effectively raise the qualification rate of casting.
Description
Technical field
The present invention relates to casting technique field, and in particular to chill and the core design method and chill for being easy to place chill
Laying method.
Background technology
Chill is divided into internal densener and external chill, and internal densener is inserted directly into position that Quench is needed in casting chamber and in cast
Being fused into one with casting, be mainly used in ferrous metal thick and large casting, external chill is divided into direct external chill and indirect external chill again, every
Sand cooling iron is one kind of indirect external chill, as its name suggests, has certain thickness layer of sand phase with being quenched between casting every sand cooling iron
Every, thus be not welded together in cast with casting.
Traditional casting technique production cycle length, complex operation, manual request is high, with the development of science and technology, 3D printing skill
Art is applied in casting field, and still, because 3D printing is integral sand core modularization moulding, the contoured chill of monoblock is not
Easily it is placed in core, and monoblock chill is not easily taken out after cast is unpacked, even if causing to produce qualified products may also
Because during taking chill to casting cause damage the problem of.
The content of the invention
For overcome the deficiencies in the prior art, the present invention provides chill and is easy to place the core design method of chill and cold
Iron laying method, the chill are formed by the filling of multiple steel shots, chilling action can be not only played to casting, and unpacking
When with core it is defeated and dispersed together, will not remain in casting chamber, effectively raise the qualification rate of casting.
The present invention is realized by following scheme：
Chill, the chill are made up of multiple steel shots.
It is easy to place the core design method of chill, the chill is made up of multiple steel shots, comprised the following steps：
Step 1：Three-dimensional cast model is established with 3 d modeling software according to the two-dimentional drawing requirement of casting；
Step 2：Three-dimensional casting technique mould according to the three-dimensional cast model in step 1 with 3 d modeling software designing cast
Type；
Step 3：Three-dimensional core model is designed with 3 d modeling software according to the three-dimensional casting technique model in step 2；
Step 4：Steel shot landfill space is set in the three-dimensional core model；
Step 5：Three-dimensional core model 3D printing according to steel shot landfill space is provided with step 4 goes out core.
Further, step 2 comprises the following steps：
Step 201：Design Fundamentals three-dimensional casting technique model；
Step 202：Running gate system is designed in 3 d modeling software, and it is cold to needing the place of feeding and Quench to place
Iron；
Step 203：According to the running gate system in step 202, the three-dimensional in step 201 is cast with casting simulation software
Process modeling carries out filling type and solidification simulation, and obtains simulating casting；
Step 204：The simulation casting that verification step 203 obtains, then such as qualified, the preliminary three-dimensional casting that step 201 designs
Process modeling is final three-dimensional casting technique model, such as unqualified, then is related in set-up procedure 201, step 202 and step 203
And the relevant parameter arrived, then repeat step 201, step 202 and step 203, qualified up to verifying, the three-dimensional after checking is qualified
Casting technique model is final three-dimensional casting technique model.
Further, the step 203 is simulated by 2/3rds of actual chill volume.
Further, step 3 comprises the following steps：
Step 301：The sand mold of three-dimensional casting technique model described in a covering step 2 is drawn in 3 d modeling software
Type；
Step 302：Using three-dimensional casting technique model described in step 2 as cutter, the sand base is inversely cut, obtains one
Overall three-dimensional core model.
Further, step 3 also includes：
Step 303：The three-dimensional core model of entirety obtained to step 302 carries out modularization cutting.
Further, step 4 includes：On the three-dimensional core model for obtaining step 3 with 3 d modeling software with casting
To being emptied in requisition for the position for placing chill.
Chill laying method, the chill that the method is related to are made up of multiple steel shots, and this method is to place chill
In the core provided with steel shot landfill space, comprise the following steps：
Step 1：Steel shot in filling, there is gap in the steel shot landfill space of core between steel shot and core；
Step 2：Steel shot is sealed with resin sand；
Step 3：After resin sand hardening a coating is brushed on resin sand surface.
Further, the gap between the steel shot and the core is 10mm.
Because 3D printing is integral sand core modularization moulding, the contoured chill of monoblock is not easy to be placed in core, and whole
Block chill is not easily taken out after cast is unpacked, in view of the above-mentioned problems, the invention provides the chill being made up of multiple steel shots, and
By designing the core with steel shot landfill space, easily chill can be put into core, laying method is also very simple
It is single that directly after cast is unpacked, the chill being made up of steel shot can be defeated and dispersed together with core, will not remain in casting chamber,
Effectively raise the qualification rate of casting；In addition, when casting structure complexity, in order to facilitate sand removal and meet core cavity core segment
Requirement, modularization cutting can be carried out to overall three-dimensional core model when designing core, then several pieces of masters are gone out by 3D printing
Body core.
