Abstract
The utility model describes a mold core device and relates to the technical field of molds. The mold core device comprises a mold kernel, a core and a frame. The core and the frame are in an overall structure; the frame covers on the mold kernel; and the core is inserted into the mold kernel. The core of the device is shorter than the existing core; an unformed part is machined and formed manually when a model is cast; the device overcomes the defect that the overlong core is very easy to damage during a production and machining course; the service life of the core is prolonged; and the cost is lowered.
Description
Technical field
The utility model belongs to technical field of mold, particularly a kind of mold cores device.
Background technology
At present, what industry was made greatly develops, to the also further increase of demand of its die industry that relates to, yet existing mold cores causes very easily being damaged in process owing to long, fails to satisfy existing production requirement, reduce service life, increased its cost.Core rod is the precision component for the key running at mold center position; Core is that when casting is in order to form internal structure.
The utility model content
The utility model provides a kind of mold cores device at the deficiencies in the prior art, has avoided the damage of core, has increased service life, reduces production costs.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme: a kind of mold cores device of the utility model, and it comprises framed, core rod and core, core and framed being formed in one, framed covering on core rod, core inserts in the core rod, and described core length is 20cm-30cm.
Beneficial effect: adopt the core shorter than original core, can avoid in the mould use, because core is long, the fracture damage that causes core, the part of moulding does not adopt the artificial machine-shaping of digging in casting, be that 20cm-30cm is best through evidence core length, if core is long or too short, do not reach efficiently, effect cheaply.
Description of drawings
Fig. 1 is the structural representation of a kind of mold cores device embodiment.
The specific embodiment
Shown in Fig. 1, that a kind of mold cores device of the utility model comprises is framed 1, core rod 2, core 3, and core 3 is formed in one with framed 1, and framed 1 covers on core rod 2, core 3 inserts in the core rod 2, its core 3 is compared length with original core to shorten for short core, and its length is 25cm, in process, because core 3 is shorter, and fail the part of moulding, by artificial cutting machine-shaping.
The length of core described above also can be 22cm, 26cm, 30cm etc.
Above-described only is preferred embodiment of the present utility model; should be understood that; for a person skilled in the art; under the prerequisite that does not break away from the utility model structure; can also make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these can not influence effect and practical applicability that the utility model is implemented.
Claims (1)
1. mold cores device, it comprises framed, core rod and core, core and framed being formed in one, framed covering on core rod, core inserts in the core rod, it is characterized in that described core length is 20cm-30cm.
