Abstract
The utility model discloses the elongated sand core structure of a kind of segmented, include multistage successively one word alignment laminating core section, the involutory surface of adjacent core section is respectively equipped with dowel hole, between adjacent core section, in dowel hole, is also respectively arranged with alignment pin.The utility model reduces the overall size of single core, reduces the labour intensity of workman.
Description
Technical field
The utility model relates to core field, is specially the elongated sand core structure of a kind of segmented.
Background technology
Existing core is elongated integral sand core, and employing is made by hand.Shortcoming is that arbor size and requirement of strength are high, and production cost is high; Make not easily consolidation by hand, core rough surface is uneven; Labor strength is large; Production efficiency is low.
Utility model content
The purpose of this utility model is to provide the elongated sand core structure of a kind of segmented, to solve prior art Problems existing.
In order to achieve the above object, the technical scheme that the utility model adopts is:
The elongated sand core structure of a kind of segmented, it is characterized in that: include multistage successively one word alignment laminating core section, adjacent core section be in alignment with each other laminating involutory surface on be respectively equipped with dowel hole, also be respectively arranged with alignment pin between adjacent core section, and alignment pin insert adjacent core section be in alignment with each other laminating involutory surface in dowel hole.
The described elongated sand core structure of a kind of segmented, is characterized in that: adjacent core section is in alignment with each other in the involutory surface of laminating, and one of them involutory surface is coated with adhesive-layer.
The utility model reduces the overall size of single core, alleviates the weight of single core, relatively little core shooter can be adopted to make segmentation core, enhance productivity; Arbor requires simple; Penetrate core surface strength processed even, consolidation is even, core smooth surface.Replace artificial manufacture by core shooter simultaneously, also reduce the labour intensity of workman.
Accompanying drawing explanation
Fig. 1 is the utility model overall structure schematic diagram.
Fig. 2 is a core segment structure schematic diagram in the utility model detailed description of the invention.
Fig. 3 is another core segment structure schematic diagram in the utility model detailed description of the invention.
Detailed description of the invention
As shown in Figure 1.The elongated sand core structure of a kind of segmented, include two sections successively one word alignment laminating core section 1,2, two core sections 1,2 be in alignment with each other laminating involutory surface on be respectively equipped with dowel hole 4, also be respectively arranged with alignment pin 3 between two core sections 1,2, and alignment pin 3 insert two core sections be in alignment with each other laminating involutory surface in dowel hole 3.Wherein core section 1 involutory surface is coated with adhesive-layer.
