Abstract
The utility model discloses a mold core, which comprises a mold core main body and a sleeve, the central axis position of the sleeve is provided with a hollow cavity, and the mold core main body is placed in the hollow cavity of the sleeve. When the mold core is broken, only the mold core main body in the sleeve needs to be replaced, so that the consumption of the mold core material can be reduced, and the manufacturing cost is reduced.
Description
Technical field
The utility model relates to the die casting industry, particularly a kind of core that is used in the die casting.
Background technology
In the die casting industry, this category feature of moulding hole or groove is mainly finished by core.For very little molding character; the core size that is complementary also can be very little; in order to prevent the core fracture; with core designs one-tenth shape as shown in Figure 1, reinforcement part A and working portion B's designer are formed in one through regular meeting, and the speed when injecting die cavity owing to melt metal is fast, pressure is big; cause the working portion of core to fracture through regular meeting; because the material cost height of core is often changed core, has caused the production cost increase.
The utility model content
For solving the problems of the technologies described above, the utility model provides a kind of core, with the purpose that realizes reducing production costs.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of core comprises core body and department's cover, and the central shaft position of described department cover is provided with cavity, and described core body is placed in the cavity of described department cover.
Preferably, cooperating between the cavity of described core body and described department cover is matched in clearance, and its gap width is 0.1～0.3mm.
Preferably, the gap width between the cavity of described core body and described department cover is 0.2mm.
By technique scheme, the utility model provides a kind of core, and split type core assembly replaces the core of original integral type, when core ruptures, only need the core body in the replacing department cover to get final product, the material that has reduced core uses, and has reduced manufacturing cost.Simultaneously, leave the gap between department's cover and the core body, be beneficial to the discharge of gas, improved the quality of injecting products.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below.
Fig. 1 is the front view of a kind of core of the prior art;
Fig. 2 is the structural representation of the disclosed a kind of core of the utility model embodiment.
The specific embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described.
The utility model provides a kind of core, comprises core body 11 and department's cover 12, and the central shaft position of department's cover 12 is provided with cavity, and core body 11 is placed in the cavity of department's cover 12.Cooperating between the cavity of core body 11 and department cover 12 is matched in clearance, and its gap width is 0.2mm.This split type core assembly replaces the core of original integral type, when core ruptures, only needs the core body in the replacing department cover to get final product, and the material that has reduced core uses, and has reduced manufacturing cost.Simultaneously, leave the gap between department's cover and the core body, be beneficial to the discharge of gas, improved the quality of injecting products.
To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the utility model.Multiple modification to these embodiment will be apparent concerning those skilled in the art, and defined General Principle can realize under the situation that does not break away from spirit or scope of the present utility model in other embodiments herein.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the wideest scope consistent with principle disclosed herein and features of novelty.
Claims (3)
1. a core is characterized in that, comprises core body and department's cover, and the central shaft position of described department cover is provided with cavity, and described core body is placed in the cavity of described department cover.
