Abstract
The utility model discloses a kind of core group of vertical core assembly, by by vertical for some cores core assembly, and is positioned by same vertically disposed support in conjunction with top cover and base and fixes.Not only make whole core group take horizontal area to reduce, the use to core box can be reduced when volume production, and vertical stacking some cores are together tightr to make integrally-built precision higher by the contact that the impact of gravity is mutual.
Description
Technical field
The utility model relates to automobile engine cylinder-body casting field, especially a kind of core group of improvement.
Background technology
At automobile engine cylinder-body casting field, the core group of employing is generally the core assembly mode of laterally being put side by side by some cores, in this core assembly mode each core rely on be placed in horizontal lengthwise base on arrange.Although this traditional core assembly structure more easily realizes, Problems existing has: 1, take horizontal space more in core box, makes the utilization rate of core box little, has to use a large amount of core boxes when volume production, adds cost; 2, owing to there is no interaction force between each core, make structure comparatively loose, in the Product Process design more and more higher to pouring technology required precision, to find that the core group precision of this horizontally set is difficult to control to better.
Therefore, need a kind of new technical scheme to solve the problem.
Utility model content
The purpose of this utility model is the deficiency existed for prior art, provides a kind of core group of vertical core assembly, can improve core box utilization rate and improve pouring technology precision in cast is produced.
For achieving the above object, the core group of the vertical core assembly of the utility model can adopt following technical scheme:
A core group for vertical core assembly, comprises base, top cover, some cores between base and top cover and support; Described core comprise and top cover against and fixing top core and base abutment fixing bed load core and at least one middle core of pushing up between core and bed load core; Described middle core is fixed on support, and the upper end of support and top cover are fixed, and lower end and the base of support are fixed.
Compared with background technology, the utility model passes through vertical for some cores core assembly, and is positioned by same vertically disposed support in conjunction with top cover and base and fix.Not only make whole core group take horizontal area to reduce, the use to core box can be reduced when volume production, and vertical stacking some cores are together tightr to make integrally-built precision higher by the contact that the impact of gravity is mutual.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, illustrate the utility model further, these embodiments should be understood and be only not used in restriction scope of the present utility model for illustration of the utility model, after having read the utility model, the amendment of those skilled in the art to the various equivalent form of value of the present utility model has all fallen within the application's claims limited range.
As shown in accompanying drawing 1 to Fig. 4, the utility model discloses a kind of core group of vertical core assembly, comprises base 1, top cover 2, some cores between base 1 and top cover 2, support 4, is positioned at the side plate 5 of all core sides.Described some cores bottom-up stacking and mutually against.Described core comprise and top cover 2 against and fixing top core 31 and base 1 against and fixing bed load core 32 and at least one middle core 33 of pushing up between core 31 and bed load core 32.Described middle core 33 is fixed on support 4, and the upper end of support 4 and top cover 2 are fixed, and lower end and the base 1 of support 4 are fixed.
In the present embodiment, described core is provided with 4, comprises cores 33 in the middle of 1 top core 31,1 bed load core 32 and 2, described in the middle of 2 cores 33 comprise 1 upper in the middle of under core 331 and 1 in the middle of core 332.
Described support 4 comprises upper bracket 41 and lower carriage 42, the upper end of described upper bracket 41 is provided with the first projection 411 coordinated with top cover 2 inner surface, the lower end of upper bracket 41 extends the second projection (not shown, position please refer to upper bracket and upper locating piece joint) downwards.Refer to shown in Fig. 3, the lower end of lower carriage 42 is provided with the 3rd projection 421 coordinated with base 1 inner surface, and the upper end of lower carriage 42 extends upward the 4th projection 422; The side of described middle core 331 is provided with locating piece 333, and on this, locating piece 333 is provided with the upper locating slot (not shown, position please refer to upper bracket and upper locating piece joint) coordinating with the second projection of upper bracket 41 and locate.Refer to shown in Fig. 2, the side of described lower middle core 332 is provided with lower locating piece 335, and this lower locating piece 335 is provided with and coordinates the lower locating slot 336 of locating with the 4th projection 422 of lower carriage 42.Described upper locating piece 333 is also located mutually with lower locating piece 335, can be realized equally, do not repeat them here by the male-female engagement of groove and projection.Described all cores are all arranged with the side groove 34 of locating with side plate 5 to same direction, and the side plate 5 of correspondence is provided with the locating convex block (not shown) coordinated with these side grooves 34 coordinates with core to make side plate 5.Upper end and the top cover 2 of described side plate 5 are fixed, and lower end and the base 1 of side plate 5 are fixed.
When the volume production of pouring practice, the core group of this vertical core assembly can take space less in core box in the horizontal, thus can place more core group in a core box, decreases the use amount of core box, reduces the cost using core box.Further, it is more accurate that vertical core assembly can make overall structure precision control under the influence of gravity, and structure is consolidation more, is conducive to the lifting to cast precision.
