Abstract
The utility model provides a kind of communication product mould removable core rod, comprise cover half frame and cover half core, the middle part of described cover half frame is provided with at a groove identical with structure with described cover half core size, described cover half core can be placed in this groove, described cover half core is divided into cover half outer core, cover half inner core and cover half ingate insert, and cover half inner core is connected by the outer core of bolt and cover half; Be connected by the dovetail groove of back draught between cover half inner core with cover half ingate insert.After communication product mould have employed this mold insert structure, the cost changing core rod greatly reduces; Meanwhile, produced die cost also decreases.
Description
Technical field
The utility model relates to electronic equipment, is specially the removable core rod of a kind of communication product mould.
Background technology
At present, communication product is due to needs lift-launch circuit board, therefore very responsive to burr, because if jagged, is easy to the short circuit causing circuit board.Accordingly, the dominant failure mode of the die casting of communication product is the product cavity burr that the be full of cracks of core material causes, and for cover half, the cover half core segment shown in figure below is if there is more be full of cracks, then whole set of die will be faced with and scrap.
Therefore, need to study a kind of device originally extending the service life of whole set of die with smaller one-tenth.
Utility model content
The technical problem that the utility model solves is to provide a kind of communication product mould removable core rod, to solve the shortcoming in above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions:
The removable core rod of a kind of communication product mould, comprise cover half frame and cover half core, the middle part of described cover half frame is provided with at a groove identical with structure with described cover half core size, and the both sides of described cover half frame are also respectively provided with a clamp.Described cover half core can be placed in this groove, and described cover half core is divided into cover half outer core, cover half inner core and cover half ingate insert, and cover half inner core is connected by the outer core of bolt and cover half; Be connected by the dovetail groove of back draught between cover half inner core with cover half ingate insert.
In the utility model, the direction at four angles of described cover half frame is respectively provided with a threaded post, for by cover half frame solid mechanical equipment.
The beneficial effects of the utility model: after communication product mould have employed this Lee mold insert structure, the cost changing core rod greatly reduces; Meanwhile, produced die cost also decreases.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of described cover half frame;
Fig. 2 is that described cover half core launches schematic diagram;
Fig. 3 is described cover half core overall schematic.
In figure: 1-cover half frame, 1.1-groove, 1.2-clamp, 1.3-threaded post
2-cover half core, the outer core of 2.1-cover half, 2.2-cover half inner core, 2.3-cover half ingate insert.
Detailed description of the invention
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
The removable core rod of a kind of communication product mould, comprise cover half frame 1 and cover half core 2, the middle part of described cover half frame 1 is provided with at a groove 1.1 identical with structure with described cover half core 2 size, described cover half core 2 can be placed in this groove 1.1, described cover half core 2 is divided into cover half outer core 2.1, cover half inner core 2.2 and cover half ingate insert 2.3, and cover half inner core is connected by the outer core of bolt and cover half; Be connected by the dovetail groove of back draught between cover half inner core with cover half ingate insert 2.3.
As shown in Figure 1, Figure 2, Figure 3 shows, the core rod of mould is divided into several module composition, the ingate insert 2.3 made is because wash away seriously at ingate position mould more, the problem chapped more easily occurs, therefore prevents by ingate insert 2.3 problem of washing away.Wherein: cover half inner core 2.2 is connected by the outer core 2.1 of bolt and cover half; Ingate insert 2.3 is because of dimensional problem, and the screwed hole that very difficult making is larger, therefore we adopt the dovetail groove of back draught to connect, and all internally gating insert 2.3 has carried out reliably locating so in the two directions.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model, the technical staff of the industry should understand, the utility model is not restricted to the described embodiments, what describe in above-described embodiment and description just illustrates principle of the present utility model, under the prerequisite not departing from the utility model spirit and scope, the utility model also has various changes and modifications, these changes and improvements all fall within the scope of claimed the utility model, the claimed scope of the utility model is defined by appending claims and equivalent thereof.
