Abstract

The utility model provides an exhaust structure for an insert of a mold. According to the exhaust structure, the mold does not need to be additionally provided with an exhaust groove, the design cost of the mold is low, the structure is further suitable for a plurality of sets of the molds, and the universality is good. The exhaust structure comprises a mold cavity formed by matching an upper mold and a lower mold, and is characterized in that the mark symbol insert is arranged below the mold cavity, the mark symbol insert comprises an external positioning mark insert and an internal rotatable insert, the internal rotatable insert is sheathed in a cavity in the external positioning mark insert, a gap exists between the internal rotatable insert and the external positioning mark insert, a ventilation hole is formed at the middle and lower part of the internal rotatable insert, and the ventilation hole is communicated with the gap through a connecting hole.

Description

A kind of mold insert exhaust structure of mould

Technical field

The utility model relates to the technical field for the higher die venting structure of requirement on machining accuracy, is specially a kind of mold insert exhaust structure of mould.

Background technology

Existing for the higher mould of requirement on machining accuracy, for example (,) notebook computer shell, when moulding, often run into the not smooth situation of exhaust, need the extra demand that air discharge duct satisfies exhaust that is provided with, the cost of mould design is high; And every mold need be according to the independent designing and arranging air drain of its structure, and versatility is poor.

Summary of the invention

To the problems referred to above, the utility model provides a kind of mold insert exhaust structure of mould, and it makes mould need not the extra air discharge duct that is provided with, and the Mould design cost is low, and this structure can be suitable for many molds, and versatility is good.

A kind of mold insert exhaust structure of mould; Its technical scheme is such: it comprises that upper die and lower die cooperate formed die cavity; It is characterized in that: the below of said die cavity is provided with the label symbol mold insert; Said label symbol mold insert comprises outside positioning mark mold insert, inner rotatable mold insert, and the rotatable mold insert in said inside is set in the said outside positioning mark mold insert internal cavities, has the gap between the rotatable mold insert in said inside, the outside positioning mark mold insert; The middle and lower part of the rotatable mold insert in said inside has passage, and said passage is communicated with said gap through connecting hole.

After adopting the structure of the utility model; Owing to generally all be provided with label symbol for the higher mould of requirement on machining accuracy, the middle and lower part that inner rotatable mold insert is led in the gap between the rotatable internally mold insert of gas, the outside positioning mark mold insert has passage, finally from the passage exhaust; It makes mould need not the extra air discharge duct that is provided with; The Mould design cost is low, and this structure can be suitable for many molds, and versatility is good.
