Abstract

The invention relates to a core combining method, which includes the steps: (1) preparing sand cores to be combined and providing a basic core and a cover plate core; (2) placing the sand cores on the basic core in a certain order, covering the sand cores with the cover plate core, positioning the sand cores between the basic core and the cover plate core and forming casting cavities among the sand cores and the basic core and among the sand cores and the cover plate core; and (3) forming tight sand cores on the basic core and the cover plate core or on two sides of each of the basic core, the sand cores and the cover plate core and connecting the basic core and the cover plate core or the basic core, the sand cores and the cover plate core into a whole sand core. By the aid of the core combining method, core combining precision can be improved, casting precision is improved from a CT9 grade to a CT6 grade, waste products generated due to core combination are avoided, and the weight of castings can be reduced by 5%. Automated operation can be realized, per-capita productivity can be greatly improved, and manual mould assembly and clamping are omitted.

Description

A kind of core assembly method
Technical field
the present invention relates to the core assembling technology field in casting, particularly relate to a kind of core assembly method.
Background technology
at present, for environmental protection, quality, cast product that product complexity is more and more higher, its conventional core assembly method is: core is divided into two or three core groups by manually combining, simultaneously with pouring into a mould after glue or screw-clamped, there is following shortcoming: 1, clamping force is inhomogeneous, the risk that has runout while simultaneously pouring into a mould, and risk is larger; 2, casting dimension fluctuation is larger, and it is more difficult to control, and only has the allowance of increasing to solve, waste resource; 3, increased casting weight the technique thermal center of foundry goods is strengthened, caused product yield low, machining period increases, and the inner defect possibility producing of foundry goods increases; 4, manual work is unfavorable for automation, is unfavorable for raising the efficiency.
Summary of the invention
the object of the invention is to provide a kind of core assembly method, the method when producing complicated especially product, the technology having, economy, odds for effectiveness.
for achieving the above object, the technical solution used in the present invention is:
a core assembly method, it comprises the following steps:
(1), prepare core to be combined, comprising a basic core, a cover plate core;
(2), core is placed on basic core in certain sequence, cover plate core cap is combined on core, core is between basic core and cover plate core, between core and basic core, form the die cavity of foundry goods between core and cover plate core;
(3), the fastening core that is shaped in basic core, cover plate core or basic core, core, cover plate core both sides, fastening core connects into an integral sand core by basic core, cover plate core or basic core, core, cover plate core.
preferably, in step (3), prepare a core assembly core box, this core assembly core box comprises core box, lower core box, on described upper core box, offers sand-spraying hole,
basic core, core and cover plate core are placed in described lower core box, cover described upper core box, make described upper core box be pressed on cover plate core top, and the sand-spraying hole on described upper core box is positioned at the both sides of basic core, core and cover plate core, by described sand-spraying hole to penetrating sand in core assembly core box, solidifying to form fastening core.
further preferably, described fastening core is shaped by cold-box process.
further preferably, on described core assembly core box, be provided with core positioning key.
preferably, described basic core, cover plate core and core are cold core or inorganic core.
preferably, described core is one or more.
because technique scheme is used, the present invention compared with prior art has following advantages and effect:
1, improve core assembly precision, make casting accuracy bring up to CT6 level from CT9 level, without the waste product occurring because of core assembly, casting weight can fall 5%;
2, can realize automated job, productivity ratio can significantly improve per capita;
3, without artificial mould assembly clamping.
Accompanying drawing explanation
accompanying drawing 1 is basic core, the schematic diagram after combining core, the assembling of cover plate core;
accompanying drawing 2 is basic core, after combining core, the assembling of cover plate core, is placed on the schematic diagram in lower core box;
accompanying drawing 3 is basic core, after combining core, the assembling of cover plate core, is placed on the schematic diagram in core assembly core box;
the schematic diagram that accompanying drawing 4 is integral sand core.
wherein: 1, basic core; 2, core; 3, cover plate core; 4, die cavity; 5, upper core box; 50, sand-spraying hole; 6, lower core box; 7, fastening core.
The specific embodiment
below in conjunction with drawings and Examples, the invention will be further described:
a core assembly method, it comprises the following steps:
(1), prepare core to be combined, comprising one or more cores 2, a basic core 1: provide basis, location to each core 2, a cover plate core 3: all cores 2 are formed and seal and provide seal face, above-mentioned each core is the inorganic core that cold core or precision are higher, and by check, revise after qualified and can use;
(2), as shown in Figure 1: core 2 is placed on basic core 1 in certain sequence, cover plate core 3 is covered on core 2, after assembling, core 2 is between basic core 1 and cover plate core 3, between core 2 and basic core 1, form the die cavity 4 of foundry goods between core 2 and cover plate core 3;
(3), preparation a core assembly core box, this core assembly core box comprises core box 5, lower core box 6, on upper core box 5, offers sand-spraying hole 50, is provided with core positioning key on core assembly core box, this core assembly core box is cold-box, adopts cold-box process to carry out coremaking,
as Fig. 2, shown in 3, basic core 1 after combination is installed, core 2 and cover plate core 3 are placed in lower core box 6, cover core box 5, make core box 5 be pressed on cover plate core 3 tops, and the sand-spraying hole 50 on upper core box 5 is positioned at basic core 1, the both sides of core 2 and cover plate core 3, by sand-spraying hole 50, in core assembly core box, penetrate sand, core sand is basic core 1 in core assembly core box, in the space of core 2 and cover plate core 3 both sides, solidify to form fastening core 7, fastening core 7 is by basic core 1, cover plate core 3 or basic core 1, core 2, cover plate core 3 connects into an integral sand core, as shown in Figure 4, integral sand core is ejected from core assembly core box, complete core assembly one time.
