Description
Technical field
Injection mold field is the utility model is related to, especially a kind of structure of injection mold.
Background technology
At present, the exhaust gap in most molding mold cavity is all that mould has just been defined width in production
Degree, if desired increase exhaust gap width, then need to transform mould structure or by and close other moulds carry out
The regulation of exhaust gap, but by and close other moulds be exhausted the regulative mode in gap the entirety of mould is fixed it is poor,
Easily there is the phenomenon of position skew, influence the quality of product.
Utility model content
The utility model is directed to above-mentioned technical deficiency, there is provided and one kind can be positioned by alignment pin to die, so as to
By the size of the positioning regulation air discharge duct of die, can be needed that the adjustment of groove size is exhausted according to the exhaust of different injection molding materials,
It is simple in construction, the structure of injection mold easy to use.
To reach above-mentioned purpose, the utility model is achieved through the following technical solutions：
A kind of structure of injection mold, including upper die and lower die, upper cores and lower die, described upper mould is positioned at above-mentioned
The top of lower mould, hollow space is provided between described upper die and lower die, described upper cores and lower die are located at hollow space
Interior, described upper cores are located at the top of described lower mould.
Further, described upper die and lower die are provided with first through hole.
Further, the number of described first through hole is at least 3.
Further, described upper cores and lower die are provided with the second through hole.
Further, the number of the second described through hole is at least 3.
Further, be combined with alignment pin in described first through hole and the second through hole, the number of the alignment pin with it is described
First through hole and the second through hole number it is corresponding.
Further, the joint surface of described upper die and lower die is provided with air discharge duct.
Further, the joint surface of described upper cores and lower die is provided with exhaust groove.
The beneficial effects of the utility model are：Die can be positioned by alignment pin, so as to determining by die
It the size of position regulation air discharge duct, can be needed that the adjustment of groove size is exhausted according to the exhaust of different injection molding materials, it is simple in construction, use
It is convenient.
