Abstract

The utility model discloses a kind of jig that water hole is bored suitable for hub mold mold core, including jig main body, index dials；Index hole is opened up in jig main body, is positioned between the index hole and index dial with pin；Arbor hole is opened up in jig main body.The utility model has the beneficial effects that changing traditional cooked mode to drill again that first draws lines using the above structure.So that workpiece is felt relieved, rapid and convenient is indexed, so that the machining accuracy in mold core water hole and working efficiency be made to be obviously improved.

Description

A kind of jig boring water hole suitable for hub mold mold core

Technical field

The utility model relates to mould manufacturing field more particularly to a kind of controlling suitable for hub mold mold core brill water hole Tool.

Background technique

Statement in this part merely provides background information related with content disclosed by the utility model, thereby increases and it is possible to no Constitute the prior art.

Units of low-pressure casting automobile hub mold is by upper mold, lower die, side form, the components such as mold core composition, mold core water hole, distribution Generally are as follows: 5 equal parts, 6 equal parts, 8 equal parts.Conventional processing methods are first to draw water hole center line in back of work, first when processing Center line drawing in water hole is just being drilled again, when boring next hole equally will centering water hole center line again, repeated with this until will be complete Portion water hole is drilled.It is not difficult to find out that conventional method is processed, each hole will centering water hole center line, efficiency be extremely low again.

Therefore the prior art has much room for improvement and develops.

Utility model content

The technical problem to be solved by the present invention is to provide a kind of special fixture, quickly feel relieved indexing to solve workpiece Problem；It can quickly feel relieved, index, save setting-out process and workpiece centering time, improve processing efficiency.

The technical solution of the utility model is:

A kind of jig boring water hole suitable for hub mold mold core, including jig main body, index dial；It is opened in jig main body If index hole, positioned between the index hole and index dial with pin；Arbor hole is opened up in jig main body.It is set in jig main body There is the T-slot connecting with board.Location hole is equipped in the jig main body.

The utility model has the beneficial effects that

(1) applicability of jig is considered to determine the outer shape of jig according to the outer diameter of each specification mold core.

(2) location hole is bored on jig, for water hole indexing positioning；Arbor hole is done, is felt relieved for mold core；T-slot is milled, is used In locking workpiece；Pin hole or keyway are designed in jig bottom, is connect with board, the quick positioning for jig.

(3) centre shaft designation and nut, for connecting mold core and index dial；Index dial is designed, bores index hole above, is used for water Hole indexing positioning；Traditional cooked mode to drill again that first draws lines is changed using the above structure.Workpiece is set to feel relieved, indexing is quick It is convenient, so that the machining accuracy in mold core water hole and working efficiency be made to be obviously improved.

Specific embodiment

Embodiment:

Refering to fig. 1 to Fig. 5, a kind of jig boring water hole suitable for hub mold mold core, including jig main body 1, index dial 2；Index hole 3 is opened up in jig main body 1, is positioned between the index hole 3 and index dial 2 with pin；It is opened up in jig main body 1 Arbor hole 4.The T-slot 5 connecting with board is equipped in jig main body 1.Location hole 6 is equipped in the jig main body 1.

The manufacturing process of the utility model: index hole is bored in jig main body, is positioned between index dial with pin, is used for Water hole indexing；Arbor hole is done, is felt relieved for mold core；T-slot is milled, for locking workpiece；It can be according to service condition in jig bottom Pin hole or keyway are designed, is connect with board, the quick positioning for jig and board.

Index dial is designed as shown in Figure 1:, bores index hole (respectively 5 equal parts, 6 equal parts, 8 equal parts) above, for water hole point Degree；Centre shaft designation and nut, for connecting mold core and index dial.

This jig of use process of the utility model is in use, first locked index dial and mold core with mandrel；Then by the heart Axis tail portion is put into jig arbor hole；Jig location hole is aligned by turning of work piece with index dial index hole, insertion pin positioning； Two sides screw pressing plate locks workpiece, and drilling can be completed；When boring next hole, pressing plate is unclamped, pin is inserted into down by turning of work piece The positioning of one division hole repeats this operation and is drilled until by all water holes.

In the description of this specification, the description of term " one embodiment " etc. means that the embodiment or example is combined to describe Particular features, structures, materials, or characteristics be contained at least one embodiment or example of the utility model.In this specification In, schematic expression of the above terms are not necessarily referring to identical embodiment or example.Moreover, the specific features of description, Structure, material or feature can be combined in any suitable manner in any one or more of the embodiments or examples.

The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the utility model, for this For the technical staff in field, various modifications and changes may be made to the present invention.It is all in the spirit and principles of the utility model Within, any modification, equivalent replacement, improvement and so on should be included within the scope of protection of this utility model.
