Abstract
The utility model relates to nowel box-closing positioning machine structure on a kind of casting sand type, belongs to the technical field that casting model powder moulding industry mould assembling location coordinates.It comprises top box sand mold and nowel sand mold, four jiaos of alignment pins that are respectively equipped with and downward protrusion one-body molded with top box sand mold of top box sand mold, and four jiaos of described nowel sand mold are formed with respectively the locating hole coordinating with described alignment pin.Its manufacturing process is simple, without manufacturing separately alignment pin core box, removes the making of location-independent pin from, effectively cost-saving, can meet mass production; Can simplify production process, compare with traditional handicraft, this utility model has more operability and simplification, saves the production time; Quality of fit is high, is difficult for dislocation, can more desirably guarantee casting quality.
Description
Technical field
The utility model relates to nowel box-closing positioning machine structure on a kind of casting sand type, belongs to the technical field that casting model powder moulding industry mould assembling location coordinates.
Background technology
In casting industry, in upper and lower sand mold mould assembling process, the conventional alignment pin that uses positions cooperation, and concrete grammar is: when moulding, alignment pin mating holes has all been made at four angles of upper nowel, and manufactures separately sand mold alignment pin.In mould assembling process, first alignment pin is inserted in nowel mating holes, then top box is sling, alignment pin is aimed to top box mating holes and coordinate.This technique has following defect: on upper nowel mould, need Design Orientation pin, and need to manufacture separately alignment pin core box, manufacturing process is relatively loaded down with trivial details; Adopting this alignment pin positioning process, can there is gap in the cooperation between alignment pin and locating hole, and alignment pin easily swings by a small margin, causes foundry goods mould shift, affects product quality.
Summary of the invention
The utility model has solved the existing problem of prior art, provides a kind of manufacturing process simple, without manufacturing separately alignment pin core box, removes the making of location-independent pin from, effectively cost-saving, can meet mass production; Can simplify production process, compare with traditional handicraft, this utility model has more operability and simplification, saves the production time; Quality of fit is high, is difficult for dislocation, can more desirably guarantee nowel box-closing positioning machine structure on the casting sand type of casting quality.
Above-mentioned technical purpose of the present utility model solves by the following technical programs: it comprises top box sand mold and nowel sand mold, four jiaos of alignment pins that are respectively equipped with and downward protrusion one-body molded with top box sand mold of top box sand mold, four jiaos of described nowel sand mold are formed with respectively the locating hole coordinating with described alignment pin.
As preferably, described alignment pin is the frustum structure that the little upper end diameter of lower end diameter is large, and described locating hole is the taper hole structure coordinating with alignment pin, can further improve the quality of fit of top box sand mold and nowel sand mold to improve the quality of products.
As preferably, the lower end circumference of described alignment pin is formed with chamfering, thereby in the time of can avoiding top box sand mold to coordinate with nowel sand mold, alignment pin lower end and locating hole collsion damage.
Therefore, the utlity model has manufacturing process simple, without manufacturing separately alignment pin core box, remove the making of location-independent pin from, effectively cost-saving, can meet mass production; Can simplify production process, compare with traditional handicraft, this utility model has more operability and simplification, saves the production time; Quality of fit is high, is difficult for dislocation, can more desirably guarantee the features such as casting quality.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
The specific embodiment
Below by specific embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: as shown in Figure 1, comprise top box sand mold 1 and nowel sand mold 2, four jiaos of alignment pins 3 that are respectively equipped with and downward protrusion one-body molded with top box sand mold 1 of top box sand mold 1, alignment pin 3 is the frustum structure that the little upper end diameter of lower end diameter is large, and the lower end circumference of alignment pin 3 is formed with chamfering 4.Four jiaos of nowel sand mold 2 are formed with respectively the locating hole 5 coordinating with alignment pin 3, and locating hole 5 is the taper hole structure coordinating with alignment pin 3.
