The utility model discloses still relate to a core assembling technology. The utility model relates to a core group and core assembly technology make the foundry goods have very high size precision, have reduced the casting defect because of the viscose brings, have also increased the maneuverability of core assembly process simultaneously.
Description
Technical field
The utility model relates to a kind of core group.
Background technology
For the very complicated valve body moulding of inner chamber, often need very many combined formation of core, these cores of assembling are the very things of difficulty under the prerequisite that guarantees size stability and higher operability, core assembly method of the prior art is as shown in Figure 1: it comprises a whole valve pocket core (12) in the middle of being positioned at, and with this as matrix chamber core, a plurality of independently valve pocket cores (11) are assembled to respectively on this matrix core by the mode of viscose glue.This technology is difficult to guarantee the size of foundry goods, and has bigger operation easier, simultaneously, in the process of using sticking bonding each valve pocket core (11) of core agent, is easy to generate defectives such as pore, and the percent defective of the valve body moulding of feasible this explained hereafter of use is high.
The utility model content
The purpose of this utility model is to improve a kind of be used to produce a kind of dimensional accuracy height of complicated valve body class component, the core group that casting is accurate, the core assembly operability is high.
For achieving the above object, the technical scheme that the utility model adopted is:
A kind of core group, comprise a plurality of its be provided with the serial connection hole and by the chamber core that is connected in series successively of serial connection hole, be separately positioned on a plurality of chambeies core of serial connection mutually two ends go up outer core and down outer core, successively pass outer core, a plurality of chambeies core, down outer core the serial connection part, be separately positioned on limit, the left side core and the right edge core of outer core, a plurality of chambeies core, following outer core both sides, upward the airtight cavity of pouring into a mould liquid is held in formation between outer core, right edge core, following outer core, limit, left side core, a plurality of chambeies core.
Because the employing of technique scheme, the utility model compared with prior art has the following advantages:
Core group that the utility model is related and core assembling technology make foundry goods have very high dimensional accuracy, have reduced the casting flaw of bringing because of viscose glue, have also increased the operability of core assembly process simultaneously.

The specific embodiment
Core group as shown in Figure 1 comprises a plurality of chamber cores 21 that it is provided with the serial connection hole and is connected in series successively by the serial connection hole, be separately positioned on the upward outer core 22 and the following outer core 23 at the two ends of a plurality of chambeies core 21 of serial connection mutually, pass outer core 22 successively, a plurality of chambeies core 21, the serial connection part 28 of following outer core 23, the fastening serial connection that is serially connected in that is used for that is arranged on two ends of serial connection part 28 goes up outer core 22 on the part 28, a plurality of chambeies core 21, the securing member 24 of following outer core 23, be separately positioned on outer core 22, a plurality of chambeies core 21, limit, the left side core 25 and the right edge core 26 of following outer core 23 both sides.As shown in Figure 3, the connecting portion of going up between outer core 22, right edge core 26, following outer core 23, limit, the left side core 25 forms the wedge structure, go up to form between outer core 22, right edge core 26, following outer core 23, limit, left side core 25, a plurality of chambeies core 21 and hold the airtight cavity of pouring into a mould liquid, by the wedge structure, make above-mentioned four combination tightr, make the core group form a firm frame-type structure.
Have characteristic face on each chamber core 21 and the last outer core 22, in the core assembly process, characteristic face is used to locate the locus of each chamber core 21 and last outer core 22.
The core assembling technology of above-mentioned core group comprises the steps:
At first, core 23 outside under on special-purpose core assembly and testing tool (not shown), placing, special-purpose core assembly and testing tool comprise a plurality of telescopic supports and test point 27, on following outer core 23, place successively a plurality of chambeies core 21 with on outside core 22, according to predetermined altitude, the characteristic face that uses support and test point 27 and be arranged on outer core 22 and a plurality of chambeies core 21 carries out the location, locus to each chamber core 21, here, scalable being meant supported test point 27 on the left and right directions of Fig. 2, can stretch into outer core 22 and chamber core 21 with the contact characteristic face, or withdraw from away from last outer core 22 and chamber core 21; Then, will be connected in series part 28 and pass outer core 22, a plurality of chambeies core 21, following outer core 23, and use special-purpose core assembly and testing tool to screw and be arranged on the securing member 24 that is connected in series part 28 ends; At last, limit, left side core 25, right edge core 26 are assembled in the both sides of going up outer core 22, a plurality of chambeies core 21, following outer core 23 that assemble, and upward outer core 22, right edge core 26, following outer core 23, limit, left side core 25, a plurality of chambeies core 21 form and hold the airtight cavity of pouring into a mould liquid.
Here, support and test point 27 at first carry out the location, locus to the chamber core 21 of current assembling, last outer core 22, when a plurality of chambeies core 21, go up outer core 22 all assembling finish after, support and chamber core 21 that 27 pairs of test points assemble, go up relative tertiary location between the outer core 22 and carry out secondary and locate.
