Abstract
A kind of digitlization is without molded core technique, and the present invention relates to casting technology fields；Its procedure of processing is as follows：Sandbox is got out, external form sand lump is made with resin sand；Processing is transferred to after sand lump hardening, with the shape for casting special Cutter Body Processing with Machining Center product sand core, obtains core box；Chill, riser, arbor etc. are put well in core box interior, prepare coremaking；Using the core box in step 3, the shape of sand core is made, obtains sand core；Sand core is taken out, remaining sand lump continues the shape of converted products shape in recycle step four, obtains the sand mold of product, you can.Sand core machining accuracy and efficiency is made to improve, and can realize multiple sand core quick manufacturings, while the external form that processing becomes needs can be continued to core box, has saved processing and molding sand cost.
Description
Technical field
The present invention relates to casting technology fields, and in particular to a kind of digitlization is without molded core technique.
Background technology
Present valve body moulding sand mold digitlization is processed respectively without mould processing technology, external form and sand core, and core-making method is first
Sand lump is made, sand lump is processed into the method for sand core to obtain sand core by the method for reusing digital control processing, and the method processing is primary only
Single sand core can be obtained, sand core adds man-hour requirement all to process in all faces, due to the limit in stage property orientation in process
System needs to position and process repeatedly, and less efficient, cost is higher, and external form needs to remake sand lump reprocessing, needs to make
Two sand lumps, not only take time and effort, but also waste raw material, increase processing cost, it would be highly desirable to improve.
Invention content
In view of the defects and deficiencies of the prior art, the present invention intends to provide a kind of reasonable designs, easy to use
Digitlization makes sand core machining accuracy and efficiency improve, and can realize multiple sand core quick manufacturings, while can be right without molded core technique
Core box continues the external form that processing becomes needs, has saved processing and molding sand cost.
To achieve the above object, the technical solution adopted by the present invention is：Its procedure of processing is as follows：
First, sandbox is got out, external form sand lump is made with resin sand；
2nd, processing is transferred to after sand lump hardening, with the shape for casting special Cutter Body Processing with Machining Center product sand core, obtains core box；
3rd, chill, riser, arbor etc. are put well in core box interior, prepares coremaking；
4th, using the core box in step 3, the shape of sand core is made, obtains sand core；
5th, sand core is taken out, remaining sand lump continues the shape of converted products shape in recycle step four, obtains the sand of product
Type, you can.
Further, the step three after twice of cast paint is brushed in the core box, then lets cool iron, riser, core
Bone etc. prepares coremaking.
After above-mentioned technique, the present invention has the beneficial effect that：A kind of digitlization of the present invention without molded core technique,
Sand core machining accuracy and efficiency is made to improve, and can realize multiple sand core quick manufacturings, while processing can be continued to core box to make it
As the external form of needs, processing and molding sand cost have been saved.

Specific embodiment
The present invention is further illustrated below in conjunction with the accompanying drawings.
Referring to as Figure 1-Figure 8, present embodiment the technical solution adopted is that：Its procedure of processing is as follows：
First, sandbox is got out, external form sand lump is made with resin sand（Such as Fig. 1）；
2nd, processing is transferred to after sand lump hardening, with the shape for casting special Cutter Body Processing with Machining Center product sand core, obtains core box（Such as figure
2）；
3rd, chill, riser, arbor etc. after twice of cast paint of core box brush, will be put well, prepare coremaking（Such as Fig. 3, Fig. 4）；
4th, using the core box in step 3, the shape of sand core is made, obtains sand core（Such as Fig. 5, Fig. 6）；
5th, sand core is taken out, remaining sand lump continues the shape of converted products shape in recycle step four, obtains the sand of product
Type, you can（Such as Fig. 7, Fig. 8）.
After above-mentioned technique, present embodiment has the beneficial effect that：A kind of number described in present embodiment
Change without molded core technique, sand core machining accuracy and efficiency is made to improve, and can realize multiple sand core quick manufacturings, while can be to sand core
Box continues the external form that processing becomes needs, has saved processing and molding sand cost.
The above is merely illustrative of the technical solution of the present invention and unrestricted, and those of ordinary skill in the art are to this hair
The other modifications or equivalent replacement that bright technical solution is made, without departing from the spirit and scope of technical solution of the present invention,
It is intended to be within the scope of the claims of the invention.
