Abstract
The present invention provides the reticular evaporative pattern that a kind of casting method and the casting method are used, generation and outward appearance so as to suppress the joint flash of the cast product with netted casting wall are cast well, and can be not limited to the configuration of netted casting wall and easily be carried out the assembling operation of sand mold.In casting method of the invention, reticular evaporative pattern is embedded in sand mold and makes to expose in die cavity of the one part to sand mold, to pouring into a mould liquation in sand mold.It is cast in well thereby, it is possible to outward appearance on the common casting wall (square tubular main part) shaped by die cavity and is integrally provided with the cast product (such as gusset) of the netted casting wall (grid wall) instead of reticular evaporative pattern in its embedded drape forming.
Description
Technical field
Netted disappear the present invention relates to what is used with the casting method and the casting method of sand casting cast product
Model is lost, wherein, the cast product has includes the netted of the network structure of trellis and honeycomb
Casting wall.
Background technology
In conventional casting method, the mutual composition surface of sand mold is located at the front end face of netted casting wall, therefore
The edge of the multiple openings having in netted casting wall largely produces joint flash, and so as to generate removing, these fly
The operation of wing waste time and energy and the degraded appearance of cast product problem.In addition, in above-mentioned conventional casting side
In method, concavo-convex and concavo-convex beyond this on netted casting wall in cast product is formed on different faces
In the case of, it is being configured to be separated and knot arranged opposite inside inner side of the netted casting wall with box-shaped casting main body
In the case of structure, following problem is produced：The structure of sand mold becomes complicated and causes the generation part of joint flash to be increased,
And the assembling operation of sand mold is wasted time and energy.
The content of the invention
The object of the present invention is to provide the netted evaporative pattern that a kind of casting method and the casting method are used
Type such that it is able to which the generation and outward appearance for suppressing the joint flash of the cast product with netted casting wall are carried out well
Casting, and the configuration of netted casting wall can be not limited to and the assembling operation of sand mold is easily carried out.
The casting method of the first technical scheme is characterised by, will include the netted of trellis and honeycomb
The reticular evaporative pattern of structure is embedded in the sand mold with curing agent solidification sand, and makes netted evaporative pattern
A part for type will pour into the liquation in sand mold and be filled in die cavity with netted disappearance to exposing in the die cavity of sand mold
The embedded region of model, is integrally provided with instead of netted so as to be cast on the common casting wall shaped by die cavity
The cast product of lost pattern and the netted casting wall in its embedded drape forming.
Second technical scheme makes reticular evaporative pattern based on the casting method described in the first technical scheme
Side in die cavity to exposing, so as to cast the state with the netted casting wall surrounded by common casting wall
Cast product.
3rd technical scheme is shaping the sand mold of sand mold based on the casting method described in the second technical scheme
The inner surface of making type forms multiple model fit recesses, by the sidepiece of reticular evaporative pattern and multiple models
It is chimeric chimeric with recess and be fixed on sand mold making type, be consequently formed for make the sidepiece of reticular evaporative pattern from by
The state that the wall of the sand mold of sand mold making type shaping is protruded, after applying sand mold coating on sand mold, cuts
The sidepiece of disconnected reticular evaporative pattern, using its section as the side of reticular evaporative pattern with the wall of sand mold
It is configured to neat face.
4th technical scheme based on the casting method described in the 3rd technical scheme, with masking glue.Band covers
Lost pattern coating is applied after the sidepiece of lid reticular evaporative pattern in the whole surface of reticular evaporative pattern,
Masking tape is peeled off after making the lost pattern paint solidification, afterwards by the sidepiece and model of reticular evaporative pattern
It is fitted together to chimeric with recess and reticular evaporative pattern is fixed on sand mold making type.
Casting method in 5th the with second to the 4th technical scheme of technical scheme described in any technical scheme is base
Plinth, sand mold by approximately parallelepiped body box structure principal mode and the type of approximately parallelepiped body shape that is housed on the inside of it
Core is constituted, for being with including chip surface mounting device, the support plinth of the movable device of lathe or gusset
Cast product and cast, the side of reticular evaporative pattern is exposed from four sides of core, and will
Gap is vacated and arranged opposite in the side of the inner surface of principal mode or other cores with the four of core sides, so that
Form die cavity.
The casting method of the first technical scheme, makes the part for being embedded in the reticular evaporative pattern of sand mold to sand mold
Die cavity in expose, by the liquation in casting sand mould, instead of reticular evaporative pattern its embedded region into
The netted casting wall of shape, therefore the mutual composition surface of sand mold will not be on netted casting wall.Thereby, it is possible to press down
Fixture has the generation of the joint flash of the cast product of netted casting wall and outward appearance is cast well.In addition, only
By changing burial place of the reticular evaporative pattern in sand mold, it becomes possible to change netted casting in cast product
The configuration of wall, thus it is different from conventional casting method, the configuration of netted casting wall can be not limited to and incited somebody to action
Sand mold is formed as simple structure.Thereby, it is possible to easily carry out the assembling operation of sand mold, and will be conventional
The casting wall of tabular be changed to netted casting wall and lightweight can be realized.
The casting method of the second technical scheme, can suppress the generation of joint flash and outward appearance well casts and has by general
The cast product of the netted casting wall that logical casting wall is surrounded.
In the casting method of the 3rd technical scheme, after applying sand mold coating on sand mold, netted disappearance is cut off
It can be excluded together with foreign matter from the part of sand mold protrusion in the sidepiece of model, it is different therefore, it is possible to prevent
Thing is mixed into the situation of liquation.
According to the casting method of the 4th technical scheme, reticular evaporative pattern is covered by lost pattern with coating, because
This can make the outward appearance on the surface of netted casting wall good.Also, with sand mold making type in reticular evaporative pattern
Model fit covered without coating lost pattern coating with the shielded adhesive tape of sidepiece that recess is fitted together to, because
This can improve positioning precision of the reticular evaporative pattern relative to sand mold making type such that it is able to improve casting product
The shape quality of product.
According to the casting method of the 5th technical scheme, the movable dress of chip surface mounting device, lathe will be included
The support plinth or a part for gusset put replace netted casting wall such that it is able to realize that chip surface is mounted
The lightweight of the support plinth or gusset of equipment etc..
Specific embodiment
