Description

The split type sprue bush structure of compression mod

Technical field

The utility model is related to die apparatus technical field, especially a kind of split type sprue bush structure of compression mod.

Background technology

At present, because sprue bush is monolithic construction, processing cover half part is thicker or sprue bush length pressure more long During casting mould, cause sprue bush difficulty of processing big, assembling is difficult, and processing, maintenance cost are high.

Utility model content

Technical problem to be solved in the utility model is to provide a kind of split type cast gate noose of compression mod be easy to and process Structure.

The utility model solves the split type sprue bush structure of compression mod that its technical problem is used, the sprue bush structure It is put together by outside cast gate body, inner side cast gate body, the inner side sprue bush body is located at outside cast gate body and spreader Between, and inner side cast gate body is detachably connected by connector with spreader, the middle setting of the outside cast gate body has First interface, the inner side cast gate body is provided with second interface, and the first interface is coaxially disposed with second interface.

It is further that the connector is screw, the inner side cast gate body is provided with screwing through hole.

It is further that the first interface, the section of second interface are circle, and second interface section circle is interior Footpath 1mm bigger than the internal diameter of first interface section circle.

The beneficial effects of the utility model are：By sprue bush structure by outside cast gate body, inner side cast gate body split and Into outside cast gate body, inner side cast gate body are processed respectively, relative to the sprue bush structure of former monoblock type, outside sprue bush Body, the length of inner side cast gate body, volume reduction, reduce difficulty of processing, reduce the process-cycle of sprue bush；It is simultaneously also square Just change, reduce replacing, maintenance cost.Further, cast gate body in inner side is detachably connected by connector with spreader, can Prevent sprue bush from play occur, giving up the throne, so as to prevent running material problem from die joint, improve sprue bush using effect.

Brief description of the drawings

Fig. 1 is dimensional structure diagram of the present utility model；

Fig. 2 is cross-sectional view of the present utility model；

Parts, position and numbering in figure：Outside cast gate body 1, first interface 11, inner side cast gate body 2, second interface 21st, spreader 3, connector 4.

Specific embodiment

The utility model is described in further detail below in conjunction with the accompanying drawings.

As shown in Figure 1 and Figure 2, the split type sprue bush structure of the utility model compression mod, the sprue bush structure is poured by outside Muzzle body 1, inner side cast gate body 2 are put together, the inner side cast gate body 2 be located at outside cast gate body 1 and spreader 3 it Between, and inner side cast gate body 2 is detachably connected by connector 4 with spreader 3, the middle setting of the outside cast gate body 1 There is first interface 11, the inner side cast gate body 2 is provided with second interface 21, and the first interface 11 is same with second interface (21) Axle is set.

Sprue bush structure is put together by outside cast gate body 1, inner side cast gate body 2, outside cast gate body 1, inner side Cast gate body 2 is processed respectively, relative to the sprue bush structure of former monoblock type, outside cast gate body 1, inner side cast gate body 2 Length, volume reduction, reduce difficulty of processing, reduce the process-cycle of sprue bush；It is also convenient for changing simultaneously, reduction replacing, Maintenance cost.Further, inner side cast gate body 2 is detachably connected by connector 4 with spreader 3, can prevent cast gate from extracting Show play, give up the throne, so as to prevent running material problem from die joint, improve sprue bush using effect.

Specifically, connector 4 preferably uses screw, inner side cast gate body 2 to be provided with screwing through hole, screw is logical through screw With spreader 3 be connected inner side cast gate body 2 by hole.Slided in first interface 11, second interface 21 for the ease of material, it is described First interface 11, the section of second interface 21 are disposed as circle, for the ease of process and assemble, as shown in Fig. 2 second interface 21 Internal diameter big 1mm of the internal diameter of section circle than the section circle of first interface 11.
