Abstract
A kind of mould with combination exhaust insert structure, comprise framed, low mold frame, upper framed in be provided with upper cores, lower die is provided with in low mold frame, the lower surface of upper cores is provided with die cavity, the upper surface of lower die is provided with lower die cavity, the involutory rear upper die cavity of upper cores, lower die and the involutory forming cavity of lower die cavity; Be provided with an exhaust groove in lower die, in exhaust groove, be filled with some pieces of inserts, be connected in series by alignment pin between insert and be fixed in lower die by this alignment pin.An insert is divided into multiple insert by the utility model, multiple insert being stringed together by alignment pin is fixed on lower die again, the block number that insert is decomposed is more, the gap formed is more, the amount that air passes through is larger, can be solved lack the situations such as material short shot because of broad-minded product injection moulding by the method.
Description
Technical field
The utility model relates to a kind of mould.
Background technology
Existing mould structure generally comprises framed, low mold frame, upper framed in be provided with upper cores, be provided with lower die in low mold frame, the lower surface of upper cores is provided with die cavity, the upper surface of lower die is provided with lower die cavity, the involutory rear upper die cavity of upper cores, lower die and the involutory forming cavity of lower die cavity.Usual injection mold can limit because of product structure; tired gas is formed at the end of Injection Molding; tired gas can be directed at product injection moulding and lack the situation generations such as material; running into this type of property condition usually can in the position of tired gas by design insert; be vented by the gap of insert and lower bolster, but run into tired broad-minded situation and just can not deal with problems completely.
Summary of the invention
In order to overcome the above-mentioned deficiency of existing mold, the utility model provides a kind of mould with combination exhaust insert structure, and exhaust effect is better.
The technical scheme in the invention for solving the technical problem is: a kind of mould with combination exhaust insert structure, comprise framed, low mold frame, described upper framed in be provided with upper cores, lower die is provided with in described low mold frame, the lower surface of described upper cores is provided with die cavity, the upper surface of described lower die is provided with lower die cavity, the involutory rear described upper die cavity of described upper cores, lower die and the involutory forming cavity of lower die cavity;
Be provided with an exhaust groove in described lower die, in described exhaust groove, be filled with some pieces of inserts, be connected in series by alignment pin between described insert and be fixed in described lower die by this alignment pin.
Further, described alignment pin is through the bottom of described insert, and alignment pin penetrates in described lower die.
The beneficial effects of the utility model are: an insert is divided into multiple insert, multiple insert being stringed together by alignment pin is fixed on lower die again, the block number that insert is decomposed is more, the gap formed is more, the amount that air passes through is larger, can be solved lack the situations such as material short shot because of broad-minded product injection moulding by the method.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
A kind of mould with combination exhaust insert structure, comprise framed 1, low mold frame 2, upper cores 3 is provided with in described upper framed 1, lower die 4 is provided with in described low mold frame 2, the lower surface of described upper cores 3 is provided with die cavity, the upper surface of described lower die 4 is provided with lower die cavity, the involutory rear described upper die cavity of described upper cores 3, lower die 4 and the involutory forming cavity of lower die cavity;
Be provided with an exhaust groove in described lower die 4, in described exhaust groove, be filled with some pieces of inserts 5, be connected in series by alignment pin 6 between described insert 5 and be fixed in described lower die 4 by this alignment pin 6.Alignment pin 6 described in the present embodiment is through the bottom of described insert 5, and alignment pin 6 penetrates in described lower die 4, realizes the fixing of insert 5.
An insert is divided into multiple insert by the utility model, multiple insert being stringed together by alignment pin 6 is fixed on lower die 4 again, the block number that insert is decomposed is more, the gap formed is more, the amount that air passes through is larger, can be solved lack the situations such as material short shot because of broad-minded product injection moulding by the method.
